    [0001] The present invention relates to an electrical substrate connector which is coupled to an associated connector in a state in which it is mounted on a wiring substrate and to a substrate connection electrical connector device. [0002] In general, in various electrical equipment, for example, a substrate connection electrical connector device 10 called a stack connector which electrically connects to each other paired wiring substrates has been widely used. . The substrate connection electrical connector device of this type is configured to provide, for example, a second electrical connector to which a second wiring substrate is connected over a first electrical connector to which a first wiring substrate is connected. so that the second electrical connector faces it, to cause the two electrical connectors to be in a mutually coupled state by lowering and depressing the second electrical connector from the upper side to the first electrical connector on the lower side from that face state face-to-face, and for electrically connecting the first and second wiring substrates to one another. When the coupling of the two electrical connectors with each other is to be accomplished in this manner, one of the electrical connectors is caused to be in a vertically inverted state, thereby disposing of the two electrical connectors facing each other. the other. However, in a general substrate connection electrical connector device, when one of the electrical connectors is vertically flipped and disposed in the manner described above, a wiring substrate on which the inverted and disposed electrical connector is mounted is positioned above the electrical connector, and the entire electrical connector is therefore in a state in which it is covered and concealed with respect to the upper side by the wiring substrate. Therefore, the position in which the electrical connector of the upper side is positioned relative to the electrical connector disposed on the lower side can not be verified, and a coupling operation can be performed in a state in which the two electrical connectors are not not in mutually appropriate mating positions. When the coupling operation is carried out in the state in which the two electrical connectors are not in the mutually appropriate coupling positions in such a way, the two electrical connectors are not sufficiently mated with each other. the other, and it is conceivable that the mating operation is terminated in a half-concordant state. In this case, insufficient conduction can be caused by shock, etc. that occurs during the use of the equipment. On the other hand, a substrate connection electrical connector device disclosed in Japanese Unexamined Patent Application Publication No. 2013-161578 cited below uses a configuration in which a portion of the operating portions of Unblocking protrudes to an outer side from a longitudinal direction of the two end portions of an electrical connector on the upper side so that the portion of the unlocking operation portions can be visually verified from the upper side. According to such a configuration, the coupling position of the electrical connector of the upper side relative to the associated connector of the lower side can be verified visually.
    [0002] However, the substrate connection electrical connector device is not provided with coupling position control means that function to precisely position the mutual coupling positions of the two electrical connectors.  Consequently, there is always a risk of occurrence of mutual interference and damage of the two electrical connectors in the operation of mutual coupling of the two electrical connectors; and if a coupling is made in a state in which the coupling positions are misaligned, the deblocking operation portions formed of resin may be broken due to interference with fasteners.  [0005] We cite Japanese Unexamined Patent Application Publication No. 2013-161578 as an example of the prior art.  [0006] Therefore, it is an object of the present invention to provide substrate connection electrical connectors and a substrate connection electrical connector device which allow easy and reliable mutual positioning of the two electrical connectors and allow for easy and reliable connection of the electrical connectors.

and that an outer shape of each of the two end portions in the longitudinal direction of the insulative housing extends along an outer shape of the guide surface or an interior area thereof.  According to the electrical substrate connection connector provided with such a configuration according to the fourth aspect, each of the outer shapes 25 of the two end portions of the insulating housing is in overlap with the outer shape of the guide element of the housing. mating or the inner area thereof.  Therefore, the outer shape of the coupling guiding element protrudes towards the outer side of the wiring substrate, and, when the two electrical connectors are mated, the mutual coupling positions of the two electrical connectors can be easily checked by visually checking the outer shape of the coupling guiding element.  Furthermore, according to the invention according to a fifth aspect, the coupling guiding element may have a covering surface which extends continuously from the guiding surface so as to cover each of the two end portions in the longitudinal direction of the insulative housing; and the overlapping surface may have a main covering surface which is arranged to face the associated connector when mating with the associated connector, a cover end surface which covers an end surface in the longitudinal direction of the insulative housing, and overlapping side surfaces which cover both end surfaces in the width direction of the housing of the insulative housing, the direction of the housing width being perpendicular to the longitudinal direction of the insulating housing.  According to the sixth aspect, it is desired that the coupling guiding element is provided in one piece with a substrate connecting portion by folding the guiding element, the substrate connection being soldered to the wiring substrate; the substrate connecting portion is formed to form a plate-shaped member which is approximately perpendicular to a surface of the wiring substrate; and a surface forming a plate thickness of the substrate connecting portion is configured to contact the surface of the wiring substrate.  According to the substrate connection electrical connector provided with such a configuration according to the sixth aspect, the plate-shaped member forming the substrate connecting portion is arranged to stand up from the wiring substrate.  As a result, the bending stiffness against the external force applied to the substrate connection portion upon mating / mutual separation of the two electrical connectors is improved, and the risk that the connecting portion of substrate can be peeled off the wiring especially when a separation of the two electrical connectors is reduced.  Furthermore, according to the invention according to a seventh aspect mutual substrate, in a substrate connection electrical connector device 10 having the substrate connection electrical connector according to any one of the first to sixth aspects and the associated connector in coupling with the electrical substrate connector, it is desired that the associated connector 15 be provided with a coupling-side guide member associated with the mating guide member; and that the mating guide member of the associated side has an associated side guide surface which guides the mating guide member to a zone on the inner side of the mating guide member of the associated side. in a plane perpendicular to a coupling direction.  According to the electrical connector device of the substrate connection provided with such a configuration according to the seventh aspect, the operation of mutual coupling of the electrical connectors can be carried out more easily and precisely by the guiding actions at the same time. Both of the coupling guiding element and the coupling guiding element of the associated side.  Furthermore, according to the invention according to an eighth aspect, it is desired that the coupling guide element of the associated side is provided with an elastic tongue which comes into elastic contact with the guide element.

and 21 having plate frame shapes. flat which form rectangular shapes approximately flat (rectangular shapes).  The insulating housings 11 and 21 are, for example, molded using a resin-based material such as a plastics material, and many contact elements 12 and 22 are disposed thereon along the longitudinal direction of the housings. insulators 11 and 21 so as to form multipolar shapes.  Hereinafter, the longitudinal direction of the insulating housings 11 and 21 is referred to as the "longitudinal connector direction", and the direction perpendicular to the "longitudinal connector

electrical connectors 10 and 20 are mutually coupled, the 3028676 15 electrode rows at the contact members 12 and the electrode rows at the contact members 22 are resiliently coupled with each other.  On the other hand, the plug connector 5 (first electrical connector) 10 and the receptacle connector (second electrical connector) 20, which have been brought into the coupling state as described above, are configured to be regulated in a state in which the coupling positions of each of them are appropriate by means of plug-side coupling guiding elements 13 and associated-side coupling guiding

wall surface of the longitudinal direction distal end side of the insulative housing 11 from the outer side and the paired side cover surfaces 13c and 13c arranged to cover vertical wall surfaces on both sides in the width direction of the insulating housing connector 11 from the outer side are provided.  [0033] Of these, the lap end surface 13b and the lap side surfaces 13c and 13c are formed to extend continuously downwardly from the main lap surface 13a, which extends approximately horizontally with respect to the first wiring substrate P1 on which the plug connector (first electrical connector) 10 is mounted, and a first plug-side guide surface 13d is formed at the portion in the continuity from the main covering surface 13a to the covering end surface 13b.  In addition, second

with the receptacle connector (second connector 10 as an associated connector, the guide surfaces engage the associated-side coupling guide member 23, which is provided to form a portion of the receptacle connector 20 later described from the upper side and slide easily 15 thanks to the guiding actions of the surfaces, which form the curved shapes.  The first plug-side guide surface 13d and the second plug-side guide surfaces 13e and 13e constituting the pin-side coupling guide member 13 in this manner are formed to extend from continuous manner to form an approximately U shape in a plan view as shown in Fig. 2, and the guide surfaces are in a layout relationship such that the second pin-end guide surfaces 13e and 13e are extend respectively from the two end portions of the first plug-side guide surface 13d, which is arranged to extend in the width direction of the connector, towards the connector inner side (central side). connector).  In addition, a fastener 13g, which is to

as shown in Figure 7C.  In a state in which the plug connector (first electrical connector) 10 is mounted on the first wiring substrate P1, the plug-side coupling guide member 13 described above is configured so that that a distal end portion in the longitudinal direction of the connector (outer end portion) of the plug-side coupling guide member 13 protrudes outwardly from an end edge portion

which they protrude from the first wiring substrate P1 to the outer side. and end portions on the outer side of the main overlay surface 13a, the two overlapping side surfaces 13c and 13c, and the second pin-end guide surfaces 13e and 13e are in an exposed state in which they protrude. from the first wiring substrate P1 to the outer side.  In addition, a reinforcing plate Pla for increasing the resistance in a coupling operation is fixed in a laminated form on a rear surface side of the first wiring substrate P1.  Here, at the two end edges forming the outer shape of the first wiring substrate P1 described above, paired cut portions Plb and Plb, which are recessed towards the inner side in the width direction. of the connector, are respectively formed at the portions where the coupling guide members of the plug side 13 of the plug connector (first electrical connector) 10 are arranged.  These cut portions Plb are formed to form approximately rectangular planar shapes.  In particular, as shown in Fig. 8, a cutting width L1 of the cut portions Plb is formed to be larger than a widthwise waist of the connector L2 of the plug connector (first connector 10) so that the entire portions of both ends in the longitudinal direction of the connector of the plug connector 10 are exposed to the outer side through the cut portions Plb.  In addition, in the present

If formed in this manner, the portions of the two longitudinal direction ends of the insulating housing 11 may be arranged so as not to protrude towards the outer side of the plug-side coupling guide members 13. Furthermore, the substrate connection portions 13f, which are to be soldered to the first wiring substrate P1, are provided integrally with the plug-side coupling guide element described above. 13.

The narrow lower surfaces corresponding to the plate-thickness portions of the plate-like elements constituting the The substrate connecting portions 13f are configured to be soldered into a state in which they are in contact with grounded electrical connection passageways (shown omitted) formed on the surface of the first wiring substrate P1 described. above. [On the other hand, the receptacle connector (second electrical connector) 21 shown in FIGS. 11 to 17 is provided with the coupling guide elements of the connector. associated side 23, which correspond to the coupling guide members of the plug side 13 of the plug connector (first electrical connector) 10 described above.

As a result, the coupling operation can be performed while the mutual coupling position relationship of the two electrical connectors 10 and 20 is approached. When the coupling operation is to be terminated, the mutual coupling position relationship of the two electrical connectors 10 and 20 is regulated to a predetermined state by the guiding actions based on the sliding of the first guide surfaces of the plug side. 13d and second plug-side guide surfaces 13e and 13e formed on the plug-side coupling guiding elements 13 and the first associated-side guide surfaces 23d and the associated second-side associated guide surfaces 23e and 23e. on the coupling guide members of the associated side 23 of the receptacle connector (second electrical connector) 20 so that the operation of mutually coupling the two electrical connectors 10 and 20 is performed easily and accurately. In particular, in the present embodiment, since the parts corresponding to the three sides of the approximately U-shaped planar shape formed by the first guide surface of the plug side 13d and the second guide surfaces of the plug side 13e. and 13e are formed of metal, the guiding action of the plug-side coupling guiding member 13 provided at the plug connector (first electrical connector) allows for reliable positioning without damaging the connectors even in a state in which the coupling positions are relatively misaligned. In addition, the outer shapes of the two end portions of the insulating housing 11 are covered with the outer shapes of the plug-side coupling guide members 13 so that the two form the same shapes and protrude towards the outer side of the wiring substrate. Therefore, when mating the two electrical connectors 26 and 20 together, the mutual coupling positions of the two electrical connectors 10 and 20 are easily verified by visually checking the two end portions of the insulating housing 11 having the The same forms as the plug-side coupling guide members 13. [0050] Furthermore, the plate-shaped members forming the substrate connecting portions 13f are arranged to stand up from the first wiring substrate P1. with the substrate width. Therefore, the bending stiffness against the external force applied to the substrate connecting portions 13f upon coupling / removal of the two electrical connectors 10 and 20 is improved, and in particular during mutual withdrawal. of the two electrical connectors 10 and 20, the risk of the substrate connection portions 13f being peeled off from the first wiring substrate P1 is reduced. On the other hand, if a portion of the plug connector (first electrical connector) 10 described above and a portion of the receptacle connector (second electrical connector) 20 serving as an associated connector are configured to have colors or In the case of mutually different shades, the relative positional relationship in the coupling operation of the two electrical connectors 10 and 20 is immediately visually checked according to the different colors, and the operation of mutual coupling of the two electrical connectors 10 and 20 is performed even more easily and accurately. [0052] Above, the invention made by the present inventors has been explained in detail on the basis of the embodiment. However, the present embodiment is not limited to the embodiment described above, and it goes without saying that different modifications can be made in the range not deviating from the spirit of the present invention. this. For example, in the embodiment described above, the cut portions Plb are provided at the end edge portions forming the outer shape of the first wiring substrate P1 so as to bring the plug connector (first electrical connector) 10 to be in the exposed state. However, for example, even when configured to be exposed through a peak hole as shown in Fig. 23, similar work / effects are achieved. In addition, in the embodiment described above, the guide surfaces 13d, 13e, 23d, and 23e provided on the coupling guide members 15 of the plug side 13 and the coupling guide elements. the associated side 23 are formed by the arcuate curved surfaces in cross-section, but may be formed by other inclined surfaces such as flat surfaces inclined to form wedge shapes. Furthermore, the recessed / protruding coupling relationship between the plug-side coupling guiding element 13 and the associated-side coupling guiding element 23 in the embodiment described above. can be arranged in an inverted relationship between the receptacle connector 10 and the plug connector 20. As described above, the present invention can be widely applied to various electrical connector substrate connector devices. used in different electronic / electrical devices.
