    [0001] The present invention relates to an electrical connector and an electrical connector device configured such that a mounting retainer is pivoted upon mounting in an associated connector to maintain a mounting state in the associated connector. . In general, in different electrical devices and so on, an electrical connector device has been widely used to connect a terminal portion of any of the various signal transmission media consisting of a flexible printed circuit board. (FPC), a flexible flat cable (FFC), a coaxial cable, or the like, to a printed circuit board. The electrical connector device is configured such that, for example, a first connector (receptacle connector) to be implanted on a printed circuit board and a second connector (plug connector) to which a signal transmission medium such as a coaxial cable is connected fit together so that the second connector is inserted into the first connector. The signal transmission is achieved by means of conductive contact elements (conductive terminals) arranged to form a multiple polarity within a connector main body unit. In this electrical connector device, a structure has often conventionally been adopted in which, in order to reduce an external electromagnetic noise influence on a transmission signal or to reduce the electromagnetic noise emitted to the outside, a surface outside of the connector main body unit (insulating housing) and / or an outer side of the contact elements is covered with a conductive shell or a shielding plate made of a thin plate metal element, thus establishing an electromagnetic shield. [0004] However, particularly in recent years, since a higher frequency of a transmission signal is obtained, it is necessary to eliminate an external electromagnetic noise influence not only from a main part of the contact elements (conducting terminals). ) but also a part connected to the circuit and also reliably prevent external emission of electromagnetic noise from a part connected to the contact elements. [0005] In a conventional electrical connector device, a conductive strip is attached to a portion connecting the contact elements and the circuit, or a conductive shell is extended to cover the connection portion. However, when the conductive strip is used, a relatively expensive method of attaching the conductive strip is added, and productivity tends to decrease. Likewise, for example, the conductive shell of the first connector (receptacle connector) is extended to cover the portion connecting the contact elements, and the circuit may not be visually verifiable by image inspection or the like. This has the disadvantage of making it difficult to examine or verify whether a connection work of the contact elements or the like is performed without hindrance. [0006] We describe in Japanese Unexamined Patent Application Publication Nos. 2007-73426 and 2011-238410 examples of the prior art. [0007] Thus, an object of the present invention is to provide an electrical connector and an electrical connector device of a simple structure allowing an easy and reliable establishment of an electromagnetic shield for a part connected to a circuit. To achieve the above object, an aspect of the present invention provides an electrical connector to be mounted (connected) in an associated connector implanted on a front surface of a circuit, with a terminal portion of a signal transmission medium connected to a connector main body unit, the electrical connector being configured such that a contact element mounted on the connector main body unit is connected to the signal transmission medium, a circuit connection tab of an associated contact element mounted on the associated connector is connected to the circuit, and the contact element is configured to make contact with the associated contact element when mounted in the associated connector. for establishing an electrical connection, and a rotational holding member rotatably provided on the connector main body unit is pivoted from a position of e mounting release to a mounting operation position when mounting in the associated connector to maintain a mounting status in the associated connector. The electrical connector adopts a structure in which the mounting retainer is provided with a plate configured to cover at least the circuit board of the associated contact element when the mounting bracket is pivoted to a mounting operation, a conductor circuit the shielding element connection of the ground connection element 30 is formed in a predetermined position on the front surface of the circuit near a portion to be connected to the circuit connection lug of the circuit. associated contact member, a ground connection unit provided on the mounting holding member is configured to make contact with the circuit ground conducting circuit when the mounting hold member is pivoted to to the mounting operation position, and the ground connection unit of the mounting holding member is formed integrally and contiguously on the armor plate. [0009] Another aspect of the present invention provides an electrical connector device comprising a first connector to which a terminal portion of a signal transmission medium is to be connected and a second connector in which the first connector mounts when the second connector is located on a front surface of a circuit, a first contact element mounted on the first connector which is connected to the signal transmission medium, a circuit connection tab of a second contact element mounted on the second connector which is connected to the circuit, and the first contact element making contact with the second contact element when the first and second connectors are mounted together to make an electrical connection, and a rotatively provided mounting holder on the first connector that is rotated from a mounting release position to a pos ition of mounting operation when mounting in the second connector to maintain a mounting state in the second connector. The electrical connector device adopts a structure in which the mounting holding member of the first connector is provided with a shielding plate which covers at least one circuit connecting lug of the second contact element when the holding member The mounting circuit is pivoted to the mounting operation position, a ground connection conductor circuit is formed in a position near a portion on the front surface of the circuit and the second circuit circuit connection leg is formed. contact element must be connected, a ground connection unit provided on the mounting holding element makes contact with the circuit-conducting conductor circuit of the circuit when the mounting holding element 5 is pivoted to the mounting operation position, and the ground connection unit of the mounting holding member is formed integrally and contiguously on the shielding plate . According to these aspects of the present invention with the structures described above, by pivoting the mounting holding member from the mounting release position to the mounting operation position once the The connectors are mounted together, the shielding plate provided on the mounting holding member externally covering the circuit connecting tab of the associated contact element or the second contact element. Therefore, simultaneously with the rotation operation of the mounting holding member when the connectors are mounted together, an electromagnetic shield with respect to the circuit-connected portion is immediately established. Likewise, the ground connection unit of the mounting holding member is connected to the ground connection conductor circuit disposed near the circuit connecting lug of the associated contact member or the second contact member. , and a ground connection is made in a position near the portion to be electromagnetically shielded. Therefore, favorable characteristics of electromagnetic shielding can be obtained. On the other hand, the circuit-connected portion is not covered with the shielding plate of the mounting hold member until the mounting hold member is pivoted to the operating position of mounting. Therefore, the connected state at the connected portion can be favorably confirmed. Here, as in yet another aspect of the present invention, the ground connection unit provided on the mounting holding member is preferably fixed by mechanical coupling means on the circuit. On the other hand, as in yet another aspect of the present invention, the ground connection unit preferably comprises a plurality of leaf spring members 10 which provide resilient contact with the ground lead circuit, and The mechanical coupling means are preferably arranged to be interposed between the plurality of leaf spring members. According to these aspects of the present invention with the structures described above, the ground connection intended to establish an electromagnetic shielding is reliably and firmly made by the mechanical coupling means, thus further improving the characteristics of the electromagnetic shielding. electromagnetic shielding.

According to these aspects of the present invention with the structures described above, the associated contact element or the second contact element is covered from the outside with the armor plate only or with both the shielding shell element 10 and the armor plate. Therefore, an electromagnetic shielding (shielding) with respect to the associated contact element or the second contact element can be further improved. [0015] Again, as in yet another aspect of the present invention, the associated connector or the second connector is preferably provided with a locking unit which holds the mounting holding member in the operating position. mounting. According to the aspect comprising the structure 20 described above, the mounting state of the two connectors is maintained favorably by the locking unit. [0017] As described above, in the present invention, the shielding plate is provided on the mounting holding member which maintains a mounting state in the associated connector or the second connector, and the plate shielding plate externally covers the circuit connection tab of the associated contact element or the second contact element. Therefore, simultaneously with the rotating operation of the mounting hold member when the connectors are mounted together, an electromagnetic shield with respect to the portion connected to the circuit is immediately established. Also, the ground connection unit provided on the mounting holding member is connected to the ground connection conductor circuit provided in the position near the circuit connection tab of the associated contact element or the second contact element for a ground connection in a position near a portion to be electromagnetically shielded, thereby obtaining favorable electromagnetic shielding characteristics and also allowing a connected state at the connection pads circuit to be favorably confirmed. Therefore, an electromagnetic shield 10 relating to the portion connected to the circuit can be easily and reliably established with a simple structure, and a reliability of the electrical connector and the electrical connector device can be substantially increased in an inexpensive manner.

[0019] An embodiment when the present invention is applied to an electrical connector and an electrical connector device for connecting a plurality of Coaxial cables to a printed circuit board is described in detail below based on the drawings. [General outline of the overall electrical connector structure] [0020] First, an electrical connector device according to the embodiment of the present invention shown in Fig. 1 in Fig. 13 is of a mounting type. horizontal, comprising a plug connector as the first connector to which coaxial cable terminal portions Sc configuring a signal transmission medium are connected, and a receptacle connector 2 as a second connector implanted on a printed circuit board B. As shown in Fig. 1, the plug connector (first connector) 1 is arranged to face the receptacle connector (second connector) 2 as an associated connector mounted in a substantially horizontal direction, and is then moved horizontally to be closer of the receptacle connector 30 along a front surface of the printed circuit board B. With this, as shown in FIG. In Fig. 2, an end portion of the plug connector 1 is inserted into the receptacle connector 2 through its opening, thereby causing the two connectors 1 and 2 to be in the mounting state. [0021] Thus, in the present embodiment, the insertion direction of the plug connector (first connector) 1 in the receptacle connector (second connector) 2 and the extraction direction in an opposite direction approximately correspond to a direction of extension of the front surface of the printed circuit B. In the following, the direction of extension of the front surface of the printed circuit B is taken as a horizontal direction, and a direction perpendicular to the front surface of the circuit printed B is taken as a vertical direction. Also, in the plug connector 1, the insertion direction of the plug connector 1 in the receptacle connector 2 as the associated connector is taken as a forward direction, and the extraction direction in the opposite direction. is taken as a direction towards the back. On the other hand, in the receptacle connector 2 as the associated connector, the extraction direction of the plug connector 1 from the receptacle connector 2 is taken as a forward direction, and its opposite direction is taken as the direction towards the back. The plug connector (first connector 25) 1 and the receptacle connector (second connector) 2 forming the electrical connector device comprise insulative housings 11 and 21, respectively, each as a connector main body unit consisting of an insulating member in an elongated narrow form. In the insulative housing (connector main body unit) 11, a plurality of conductive contact elements (conductive terminals) 12 are arranged as contact elements along a longitudinal direction (vertical direction with respect to the sheet 3027163 12 of paper of Fig. 7) of the insulative housing 11 to form a multiple polarity with appropriate pitches. In the insulative housing (connector main body unit) 21, a plurality of conductive contact elements (conductive terminals) 22 are disposed as contact elements along a longitudinal direction (vertical direction relative to the paper of Fig. 7) of the insulative housing 21 to form the multiple polarity with the appropriate steps. In the connectors 1 and 2 described above, a rear edge portion of the plug connector (first connector) 1 has terminal portions of a plurality of coaxial cables Sc coupled in two upper and lower stages, the coaxial cables Sc being arranged parallel to each other along the longitudinal connector direction to form a multiple polarity. The coaxial cables Sc on the upper and lower stages have an arrangement ratio shifted in position by half a step relative to each other in a multipolar arrangement direction (longitudinal connector direction). At the terminal portion of each coaxial cable Sc, as shown in Fig. 10 and Fig. 11, a coating member is peeled off to provide a central cable conductor (signal line). SCa and an outer cable conductor (shield line) SCb to be exposed coaxially. The central cable conductor SCa disposed along a central axis line of the coaxial cable Sc is connected to the conductive contact elements (conductive terminals) 12 and 22 for signal transmission, thereby forming a signal circuit. The connection structure of the central cable conductor SCa will be further described in detail below. The outer cable conductor SCb arranged to concentrically surround an outer perimeter of the central cable conductor SCa described above is arranged, for each of the two upper and lower multipole arrangement stages 5, of way to penetrate through the inside of a GB ground bar forming a conductive ground element. Each of the two upper and lower ground bars GB in the present embodiment is formed of an elongate narrow block-shaped member extending in a long shape along the multipolar arrangement direction (direction). longitudinal connector) Sc coaxial cables described above. Each ground bar GB is connected to the outer cable conductor (shield line) SCb of the coaxial cable Sc by welding, stamping, pressure welding, or the like in a collective manner. Each of the ground bars GB on the two upper and lower stages provided as described above is connected to a ground circuit formed on the printed circuit B by means of a conductive shell or the like, which will be described further below. [Insulating Housings and Conductive Contact Elements] As described above, these electrical connectors, i.e., the plug connector (first connector) 1 and the receptacle connector (second connector 2, include elongated narrow insulating housings (connector main body units) 11 and 21 extending in an elongate narrow shape in the multipolar arrangement direction (longitudinal connector direction) of the conductive contact elements (conductive terminals). ) 12 and 22, respectively. The conductive contact elements 12 and 22 mounted on the insulating housings 11 and 21, respectively, are formed to have different shapes in a manner corresponding to the coaxial cables Sc on the two upper and lower stages described above, and the conductive contact elements 12 and 22 of two types, with those adjacent to each other in the multipolar arrangement direction (longitudinal connector direction) having different shapes, are arranged alternately. Here, the insulating housing 11 provided on the plug connector 1 is formed to extend in the longitudinal connector direction (multipolar arrangement direction) as described above, and is configured to include as a single piece a main body support unit 11a disposed within the plug connector 1 to form a connector main body unit and a mounting projection 11b provided to extend towards the before from the main body support unit 11a. Inside the insulating housing 11 with respect to the main body support unit 11a above the mounting projection 11b, GC ground contacts are integrated so as to be in contact with the ground rods GB on the two upper and lower stages described above. Furthermore, in a part of the insulating housing 11 described above with respect to the main body support unit 11a above the mounting projection 11b, the conductive contact elements (first contact elements 12 are integrally molded with insert or press-fitting by being exposed from each of the upper and lower surfaces of the insulating housing 11. That is, in the conductive contact elements 12 formed to have two types those of one type are arranged extending substantially horizontally so as to be exposed upwardly from an upper surface of the insulating housing 11 (see Fig. 11 and Fig. 13), and those of the other type are arranged extending substantially horizontally so as to be exposed downwardly from a lower surface of the insulative housing 11 (see Fig. 10 and Fig. 12). The conductive contact elements 12 of these two types are arranged alternately in the multipolar arrangement direction (longitudinal connector direction). On a rear end portion of each of the conductive contact elements (first contact elements) 12 provided on the plug connector (first connector) 1, the central cable conductor (signal line) SCa is connected. by welding when the conductive contact elements 12 abut them both from above and from below. The solder joint between the central cable conductors SCa and the conductive contact elements 12 can be made collectively. In this way, the coaxial cables Sc are connected to the conductive contact elements 12 of the plug connector 1. On both the upper and lower surfaces of the mounting projection 11b provided at a front end of the insulating housing (Connector main body unit) 11 as described above, terminal electrode units 12a forming a front portion of the conductive contact elements described above (first contact elements) 12 are disposed of. to form exposed multipolar electrodes. When the plug connector (first connector) 1 is mounted in the receptacle connector (second connector) 2 as described above, the terminal electrode units 12a forming a forward-extending portion conductive contact elements 12 abut on the conductive contact elements (second contact members) 22 provided on the receptacle connector 2 to form a signal transmission circuit. It should be noted that these conductive contact elements 12 and 22 can be configured for a ground connection. The conductive contact elements (second contact elements) 22 mounted on the insulative housing (connector main body unit) 21 of the receptacle connector (second connector) 2 are configured to be arranged such that those of Two types corresponding to the two types of conductive contact elements (first contact elements) 12 in the plug connector (first connector) 1 described above form a multiple polarity. That is, of the conductive contact elements 22 formed to have two types, those of one type are arranged to extend above the conductive contact elements 12 disposed on the floor (see Fig. 11 and Fig. 13), and those of the other type are arranged to extend below the conductive contact elements 12 disposed on the lower floor (see Fig. 10 and Figs. Figure 12). The conductive contact elements 22 of these two types provided on the receptacle connector 2 are configured to come into elastic contact with the conductive contact elements 12 of both types in the plug connector 1 from above and from below when the Electrical connectors 1 and 2 are mounted together. Likewise, a rear end portion (a right side of FIG. 10 in FIG. 13) of each of the conductive contact members (second contact members) 22 provided on the receptacle connector (second connector) 2 is provided with a circuit connecting tab 22a formed to extend along the surface of the printed circuit B described above.
    [0002] In practical use, these circuit connecting tabs 22a may be collectively subjected to a solder joint after being placed on a signal conduction circuit or a conductive ground connection circuit on the printed circuit board B described therein. above. The conductive contact members (second contact members) 22 in the present embodiment are shaped to be bent to stand upwardly relative to the circuit connecting tabs 22a disposed at the portion of the portion 22a. the rear end described above, and extend in a cantilevered form from an upper end portion of a forward vertical portion (a left side of FIG. 10 in FIG. ). A leading end portion of each of the conductive contact elements 22 is provided with a contact protrusion 22b protruding in a mountain shape downward on the multipolar upper arrangement stage and upward on the multipolar stage of the multipolar stage. lower arrangement. An apex of a lower end side and an upper side of each of the contact protrusions 22b provided on the conductive contact elements 22 is configured to resiliently engage the electrode unit. terminal 12a of the contact conductive member (first contact member) 12 in the plug connector 1 when the plug connector 1 (first connector) mounts into the receptacle connector (second connector) 2 as has been described above. With this resilient contact relationship, the electrical connection between terminal electrode units 12a and contact projections 22b described above is realized. [With respect to conductive shells (shielding shell elements)] [0034] External surfaces of the insulating housings (connector main body units) 11 and 21 provided on the plug connector (first connector) 1 and the receptacle connector (second connector) 2 are covered with conductive shells (shielding shell elements) 13 and 23, respectively, each formed by folding a thin plate metal member into a suitable shape. These conductive shells 13 and 23 are mounted as elements for providing electromagnetic shielding by covering the signal transmission circuit and the ground circuit formed inside the connectors 1 and 2, respectively, and serve also as elements configuring part of the ground circuit. Here, the conductive shell (shielding shell element) 13 provided on the plug connector (first connector) 1 consists of a mounted body of paired shell part elements surrounding the insulating housing (unit of connector main body) 11 from above and from below. Once the two ground rods (ground members) GB are soldered to the coaxial cables Sc, the two upper and lower half shell portions of the conductive shell 13 are fixed to cover the insulating housing. (Connector main body unit) 11 from above and 25 from below. On a top surface and a bottom surface of the conductive shell 13 formed of the shell member members, a plurality of ground connection tabs 13a are formed by cutting along the longitudinal connector direction, i.e. say the multipolar layout direction. Each of these ground connection tabs 12a is formed to scribe upwardly to form a cantilever blade spring shape which protrudes in a diagonal direction toward a space within the connector, and 3027163 19 makes an elastic contact with or is soldered to an upper surface side of the GB ground bar described above. [Conductor shell (shielding shell element) 5 of receptacle connector] [0036] On the contrary, as shown in FIG. 1 and FIG. 2, the conductive shell (shielding shell element) 23 provided on the connector The receptacle (second connector) 2 as the associated connector is provided with hardware holding pieces 23a at both ends in the longitudinal connector direction so as to surround the conductive shell 23 from the outside. The material holding pieces 23a are provided in pairs on one side in the longitudinal connector direction, with a lower edge of each holding hardware piece 23a connected by welding to the ground connection conduction circuit formed on the printed circuit board B, thereby establishing an electrical connection of the ground circuit and firmly securing the entire receptacle connector 2. [0037] Similarly, the two material holding pieces 23a disposed at both ends in the longitudinal connector direction as has been described. above are connected in one piece by an upper shell plate 23b extending flat along the upper surface of the insulative housing (connector main body unit) 21. The conductive shell configured as above 23 and the insulative housing described above 21 form the connector main body unit. [Mounting Holding Element] [0038] Next, as shown in FIG. 2 in FIG. 4, a mounting state of the connectors 1 and 2 with the plug connector (first connector) 3027163 which mounts in the receptacle connector (second connector) 2 is held by the holding force of the mounting holding member 14 provided on the plug connector 1. When the plug connector 1 mounted in the receptacle connector 2 is removed from the receptacle connector 2, a release operation of the mounting holding member 14 is performed, thereby causing the connectors 1 and 2 to be in a removable state. [0039] More particularly, as shown in FIG. 9, the mounting holding member 14 is rotatably mounted on the conductive shell 13 of the plug connector (first connector) 1 described above. Rotation axis units 14a provided at both ends of the mounting holding member 14 in the longitudinal connector direction are rotatably inserted into matched bearing units 13d in a free fit state, the units Coupled bearing housings 13d are provided at both ends of a rear end portion of the conductive shell 13 in the longitudinal connector direction. The paired rotation axis units 14a provided on the mounting holding member 14 are each formed such that its cross-sectional area has a substantially rectangular shape, and configured so that a pressure force a spring regulating member 13e provided on the bearing unit 13d is transmitted to any flat surface forming an outer perimeter surface of the rotational axis unit 14a. Due to this pressing force of the spring regulating member 13e, the rotational axis unit 14a is held in a "mounting release position" or in a "mounting operation position", which will be described further below. Similarly, from the outer end portions on both sides of the rotational axis unit 3027163 21 14a described above in the longitudinal connector direction, paired coupling arms 14b extend approximately along a direction of rotation radius. End portions, i.e. extension end portions, of these coupling arms 14b on one rotational side are connected in one piece together by a shield plate 14c extending into a plate shape along the longitudinal connector direction. With an operator now holding a portion of the shielding plate 14c to apply a suitable rotational force, the entire mounting hold member 14 is rotated between the "mounting release position" and "operating position of FIG. In FIG. 8. As shown in FIG. 2 and the assembly "shown in FIG. 3 shown in FIG. 1 and and FIG. 7, the shielding plate 14c provided on the holding element of FIG. 14 is formed in a shape which is folded to form a staircase shape 20 in a side view, and comprises an upper surface shielding cap 14c1 which covers, from above, the conductive contact elements (second contact members) 22 of the receptacle connector (second connector) 2 described above when the holding element 25 for mounting 14 is rotated to the "mounting operating position". The upper surface shield cap 14c1 extends to form a flat plate shape. From an edge of the upper surface shield cap 14c1 on an outer side of the radius of rotation, a rear surface shield cap 14c2 extends in one piece while being substantially bent at right angles. The rear surface shield cap 14c2 extends downward from the edge of the upper surface shielding cap described above 14c1 when the mounting bracket 14 is rotated to the 'mounting operation'. Furthermore, at a lower edge of the rear surface shielding cap 14c2 5 when the mounting holding member 14 is pivoted to the "mounting operation position", a connection plate 14c3 mass folded substantially at right angles to extend rearward of the receptacle connector 2 is provided in one piece and consecutively. In the following, the structure of each of these components of the shield plate 14c is described in detail below. The upper surface shielding cap 14c1 forming part of the mounting holding member 14 is constituted by a flat plate member extending from end portions of the coupling arms described above 14b in FIG. radius of rotation towards the rear of the receptacle connector (second connector) 2. At the two edge portions of the upper surface shielding cap 14c1 in the longitudinal direction of the connector, the locking plates 14d bent substantially at right angles to extend downward are provided in one piece and consecutively. These locking plates 14d are arranged to face each other in the longitudinal connector direction, and each of the locking plates 14d has a locking engagement hole 14e formed to penetrate therethrough. When the mounting hold member 14 is rotated to the "mount operation position" as described above, a lock unit provided on the receptacle connector 30 (second connector) 2 is engaged. in the blocking engagement hole 14e formed to penetrate through the blocking plate 14. [0044] In more detail, each of the material holding pieces 23a provided on the conductive shell 2327163 23 of the receptacle connector (second connector) 2 is provided with a locking unit 23a1 which fits slightly in the locking engagement hole 14e of the rotatably holding mounting member 14 to the "mounting operating position" described herein. -above. The blocking unit 23a1 consists of a leaf spring member extending outwardly in the longitudinal connector direction. As described above, when the plug connector 1 mounts in the receptacle connector 2 and the mounting retainer 14 is then rotated to a position near the "operating position of 14d, the locking plates 14d provided on the mounting holding member 14 move to pass over the outer extension portions of the locking units 23a. The blocking units 23a1 are then resiliently displaced so as to fall inside the locking engagement holes 14e of the mounting holding member 14 to establish a engaged state, thereby causing the mounting holding member 20 complete to be resiliently held in the "mounting operation position". Thus, with the mounting of the plug connector 1 in the receptacle connector 2, when the mounting holding member 14 is rotated from the "mounting release position 25" to the "operating position" the two connectors 1 and 2 are held in a mounting state without being separated by an external force within a predetermined range. In addition, as described above, the upper surface shield cap 14c1 forming the shield plate 14c of the mounting hold member 14 is provided to extend substantially into a flat plate shape between the parts at the ends of paired coupling arms 14b. As shown in FIG. 3 and FIG. 4 in particular, when the holding element 14 is pivoted to the "mounting operating position" when the connectors 1 and 2 are mounted together, the upper surface shield cap 14c1 has an overlapping arrangement relationship of the conductive contact members (second contact members) 22 of the receptacle connector 2 from above, thereby providing electromagnetic shielding with respect to a signal 10 of transmission. The upper surface shielding cap 14c1 is thus formed in a shape covering the conductive contact elements 22 from above, and the upper surface shielding cap 14c1 has a width dimension in the longitudinal direction of a slightly longer established connector 15. that a multipolar arrangement width in which the conductive contact elements 22 are arranged. With this, the plurality of conductive contact elements 22 in the multipole arrangement is configured to be fully covered over. Likewise, as described above, the rear surface shielding cap 14c2 of the mounting holding member 14 pivoted to the "mounting operation position" is disposed at the level 25 the rear portion of the conductive contact elements (second contact elements) 22 provided on the receptacle connector (second connector) 2. The rear surface shield cap 14c2 as rotated to the "mounting operating position" Is arranged to stand upward from the front surface of the printed circuit board B to a position near an end portion of the circuit connection tabs 22a of the conductive contact elements 22. Thus, with the hood rear surface shielding 14c2 disposed in the position near the circuit connecting tabs 22a of the conductive contact elements 22 and circuit connecting tabs 22a of the conductive contact elements 22b externally inducted by the rear surface shield cap 14c2, an electromagnetic shield with respect to the circuit connecting tabs 22a of the conductive contact elements 22 is established. Furthermore, in the present embodiment, in addition to the upper surface shielding cap 14c1 and the rear surface shielding cap 14c2 forming the shield plate 14c of the plug connector (first connector) 1, as shown in FIG. this has been described above, the material holding pieces 23a of the conductive shell 23 provided on the receptacle connector 2 (second connector) cover the conductive contact elements (second contact elements) 22 on both sides in the direction longitudinal connector. That is, the entire conductive contact members 22 are covered by the shield plate 14c of the plug connector 1 and the conductive shell 23 of the receptacle connector 2, thereby favorably providing electromagnetic shielding relative to each other. to the conductive contact elements 22. When the connectors 1 and 2 are mounted together, the terminal electrode units 12a of the conductive contact elements (first contact elements) 12 and the contact projections 22b of the contact elements The conductive contacts (second contact elements) 22 are in a connected state, and their connected portion is covered with the conductive shells described above 12 and 23 from the outside. In addition, the ground connection plate described above 14c3 extending from the lower edge of the rear surface shielding cap 14c2 forms a "ground connection unit" in the present invention, is formed so as to be contiguous in one piece to the rear surface shield cap 14c2 which forms a portion of the shield plate 14c, and is comprised of a plate member extending along the front surface of the printed circuit board B when the holding element 14 is pivoted to the "mounting operating position" as described above. In the ground connection plate 14c3, a plurality (four) of leaf spring members 14c4 to be in contact with ground connection conductor circuits B1 formed on the front surface of the printed circuit B is formed. . These leaf spring elements 14c4 each consist of an elastic member 15 obtained by cutting off a portion of the mass connection plate described above 14c3 in order to erect in a cantilevered shape, and are arranged to be aligned in parallel in the longitudinal direction of connector. On the front surface of printed circuit board B 20 described above, the plurality (four) of ground connection conductor circuits B1 is formed in parallel in the longitudinal connector direction in positions near the back of the legs. circuit connection 22a provided on the conductive contact elements (second contact elements) 22 of the receptacle connector (second connector) 2. These ground connection conductor circuits B1 are provided in positions corresponding to the leaf spring elements. 14c4 of the ground connection plate 14c3 described above. The ground connection conductor circuits B1 are arranged such that the leaf spring members 14c4 provided on the ground connection plate 14c3 resiliently establish contact with the ground connection conductor circuits B1 from above. when the mounting holding member 14 is rotated to the "mounting operation position" as described above. Thus, with the ground connection plate 14c3 making contact with the ground connection conductor circuits B1 through the leaf spring members 14c4, a ground circuit is formed. Likewise, at a substantially central portion of the ground connection plate 14c3 provided on the mounting holding member 14 as described above in the longitudinal connector direction, a hole 14c5 for attaching a fixing screw 15 as a mechanical coupling means is formed in the holding element 14 to penetrate through. In addition, a circuit mounting hole B2 is formed in the printed circuit board B to penetrate through and to cover a lower side of the ground fixing hole 14c5 provided in the ground connection plate 14c3. [0054] Once that the mounting holding member 14 is pivoted to the "mounting operating position", the fixing screw (mechanical coupling means) is inserted from above into the ground fixing hole 14c5 provided in the ground connection plate 14, and a screw-shaped portion of the fixing screw 15 penetrates through the ground connection plate 14c3 in order to be screwed into the circuit fixing hole B2 in the printed circuit B for fixation. With this operation of mounting and securing the fixing screw 15, the leaf spring elements 14c4 of the ground connection plate 14c3 described above are firmly in contact with the ground connection conductors B1. , thereby increasing electrical connectivity. Here, the fastening screw (mechanical coupling means) in the present embodiment is disposed in a portion between the adjacent leaf spring members 14c4 in the longitudinal connector direction, thereby causing the fixing screw fixing operation described above to be efficiently transferred to the leaf spring elements 14c4 and thus increasing the contact capacity of the leaf spring elements 14c4 with respect to the ground connection conductor circuits [0056] According to the embodiment of the present invention with the structure described above, with the mounting holding member 14 pivoted from the "mounting release position" to the "position 15". assembly operation "once the connectors 1 and 2 are mounted together, the shield plate 14c provided on the mounting holding member 14 externally covers the legs conne circuit 22a of the conductive contact elements (second contact elements) 22 of the receptacle connector (second connector) 2. Consequently, simultaneously with a rotation operation of the mounting holding element 14 when the connectors 1 and 2 are mounted together, an electromagnetic shield with respect to the circuit connecting tabs 22a is immediately established. Similarly, simultaneously with this electromagnetic shielding establishment, the ground connection plate (ground connection unit) 14c3 provided on the mounting holding element 14 is connected to the ground connection conductor circuits B1 arranged near the circuit connecting tabs 22a conductive contact elements (second contact members) 22 of the receptacle connector (second connector) 2. Therefore, a ground connection is made in a position near a subject part. to electromagnetic shielding, thus obtaining favorable characteristics of electromagnetic shielding. Furthermore, the circuit connection tabs 22a, which are parts of the conductive contact elements (second contact elements) 22 to be connected to the printed circuit board B, are not covered with the ground connection plate. (Ground connection unit) 14c3 of the mounting hold member 14. Accordingly, the state connected at the circuit connection tabs 22a is favorably confirmed. Still further, in the present embodiment, the ground connection plate 14c3 provided on the mounting holding member 14 is connected to the ground connection conductor circuits B1 via the spring elements. 14c4, and is fixed by means of the fixing screw (mechanical coupling means) 15. Therefore, a ground connection for electromagnetic shielding can be reliably and firmly made, improving even further. thus electromagnetic shielding characteristics. Although the invention of the present inventor has been specifically described on the basis of the embodiment, the present invention is not intended to be limited to the embodiment described above, and it is unnecessary to that the present invention may be varied in a variety of ways without departing from the essence of the present invention. For example, while the conductive shell 23 is attached to the receptacle connector (second connector) 2 as an associated connector in the embodiment described above, the present invention can be applied in a similar manner to an electrical connector device comprising an associated connector of a type not having a conductive shell attached thereto. That is to say, while the entire contact conductive elements 22 are covered with both the shield plate 14c and the conductive shell 23 of the outside of the printed circuit B in the form of As described above, the entire contact conductive elements 22 can be covered only with the shielding plate 14c of the outside of the printed circuit B. [0063] In addition, in the embodiment described above, with the fixing screw 15 as mechanical coupling means inserted in the ground fixing hole 14c5 and the screw-shaped part of the fixing screw 15 screwed into the circuit fixing hole B2 of the printed circuit B, the 14c3 ground connection is mounted and fixed. However, the present embodiment is not limited thereto, and all the other various mechanical coupling means can be simultaneously adopted. For example, instead of forming the mass attachment hole 14c5 in the ground connection plate 14c3, an elastic locking piece extending from a single holding from the ground connection plate 14c3 can be formed in the position where the ground fixing hole 14c5 is formed, and can be engaged in the circuit fixing hole B2 in the printed circuit B, thereby serving as mechanical coupling means. In this case, an engagement force of the locking piece is provided greater than the contact pressure of the leaf spring members 14c4 formed in the ground connection plate 14c3 to be transmitted to the ground connection conductor circuits. In addition, while the mechanical coupling means in the embodiment described above are arranged in the portion between the leaf spring members 14c4, this is not intended to be 5 restrictive, and a plurality of mechanical coupling means may be provided so as to have the leaf spring elements 14c4 interposed between. Still further, the present invention is not limited to a coaxial cable connector as in the embodiment described above, and may be applied in a manner similar to an insulated cable connector, a connector an electrical connector of a type in which a plurality of coaxial cables and insulating cables are mixed, an electrical connector to which a flexible circuit or equivalent is connected, a circuit circuit connector for interconnecting printed circuit boards, and so on. . As described above, the present embodiment can be applied in a general manner to different electrical connectors for use in different electrical devices.
