    [0001] ELECTRICAL CONNECTOR CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the priority of Japanese Patent Application No. 2014-204906 filed October 3, 2014, the contents of which should be considered as part of this application. FIELD [0002] The present application relates generally to an electrical connector having contacting contacts which are connected to signal terminals provided on a plate-shaped signal transfer member such as a printed circuit board. flexible (FPC) and a flexible flat cable (FFC) for electrically coupling the signal terminals on the signal transfer element with other electrical parts, of the type connected to a signal transfer element and mounted on a card printed circuit board or the like. STATE OF THE PRIOR ART [0003] In order to electrically connect a relatively small signal transfer element, such as a FPC and an FFC mounted on various types of electrical devices, to a printed circuit board on which various parts are mounted. In many cases, an electrical connector is electrically connected and fixed (mounted on) the printed circuit board. With such an electrical connector mounted on such a printed circuit board, when the connection portion of a contact of a conductive material and constituting the electrical connector (the part intended for example to be welded to an electrode on the printed circuit board on which the electrical connector is mounted) and the housing wall surface of an insulating material and facing the connection portion are closely spaced, solder or flux may flow between the connection portion and the housing wall surface during reflow soldering of the printed circuit board to the connecting portion. The same phenomenon occurs when the lower rod extending the connection portion and the housing wall surface, facing the lower rod, are very close together. The solder or flux may flow between the lower rod and the housing wall surface. In addition, the weld or flux may flow between the coupling portion coupling the lower rod to the upper rod facing the lower rod and the housing wall surface facing the coupling portion, sink between the upper rod and the housing wall surface facing the upper rod and adhering to the contact portion provided on the upper rod (the part making contact with a signal terminal of the signal transfer element). Here, the flux contains plant resins such as pine resin which dissolve upstream of the weld and remove the oxides and contaminants present on the surface of the weld and the molten metal part. Since the flux adheres to the contact portion, the transmission between the contact portion and the signal terminal of the signal transfer element is disturbed. An electrical connector to avoid this problem is known and described in the patent literature document 1. [0008] In the electrical connector described in the patent literature document 1, the distance between the connection portion and the wall surface of the The housing facing the connection portion is larger than the distance between the lower rod and the housing wall surface facing the lower rod (see, for example, Fig. 1 of the patent literature 1). This structure prevents solder or flux from flowing between the connecting portion and the housing wall surface. In other words, it prevents capillary action between the connecting portion and the housing wall surface. In the electrical connector described in the patent literature document 1, the solder or the flux do not flow between the connection portion and the housing wall surface and the solder or the flux do not flow either between the lower rod and the upper wall surface. Therefore, the electrical connector described in patent literature 1 is capable of preventing flux from adhering to the contact portion. LIST OF DOCUMENTS CITED LITERATURE PATENT [0010] Patent Literature 1: Japanese Patent Application Kokai No. 2009-81073 not discussed. SUMMARY [0011] In the context of a request for miniaturization of electrical parts, efforts were made, in the design of the electrical connector described in patent literature 1 and similar connectors, to reduce the gap between contacts having an upper rod and a lower rod (smaller spacing). Therefore, efforts have been made to reduce the distance between the connection portion and the housing wall surface facing the connection portion as well as the distance between a contact and the contact-facing housing wall surface. Due to the abovementioned reduction, in the electrical connector described in Patent Literature Document 1, the distance between the connection portion and the housing wall surface and the distance between a contact and the wall surface of the housing. housing are small enough for the solder or flow to flow. In other words, the distance is small enough to cause capillary action. Therefore, the problem with the electrical connector described in the patent literature 1 is that it would not prevent the flow from adhering to the contact portion when the abovementioned reduction is implemented. The present disclosure takes into account the circumstances described below and aims to provide the possibility of preventing the flow to adhere to the contact portion even if the spacing between the contacts is reduced.
    [0002] SOLUTION OF THIS PROBLEM [0014] In order to achieve the above purpose, the electrical connector according to the present disclosure comprises: an insulative housing having an insertion slot into which a plate-shaped signal transfer member can be inserted; and a plurality of conductive contacts each having an upper rod extending from the rear to the front of the insertion slot and having a contact portion engageable with a signal terminal on one side of the a signal transfer member inserted in the housing and a lower rod extending from the rear to the front of the insertion slot, facing the upper rod so as to clamp the signal transfer element in cooperation with the upper rod, and having at the end located at the front of the insertion slot a fully unconnected connection portion which can be connected to a support, wherein the housing comprises: a lower housing extending from the rearwardly at the front of the insertion slot and having a flat plate-shaped mounting surface extending in the arrangement direction of the lower rods and on which the lower rods are mounted; and ribs provided on the mounting surface and extending from the rear to the front of the insertion slot to form grooves for holding the lower rods, and the ends of the ribs located at the front of the insertion slot are arranged so that they are closer to the rear of the insertion slot than the end of the lower housing located at the front of the insertion slot. In addition, it is possible that: the lower rod comprises: a long lower rod on the mounting surface and extending from the rear to the front of the insertion slot; and a curvature disposed between the end of the long lower shank at the front of the insertion slot and the connecting portion and whose surface facing the mounting surface is bent toward the upper shank to form a gap from the mounting surface, and the ends of the ribs at the front of the insertion slot are closer to the rear of the insertion slot than the junction point between the long rod lower and curvature. In addition, it is possible that: the curvature extends beyond the end of the lower housing located at the front of the insertion slot, so that the connection portion is disposed at a distance of the end of the lower housing located at the front of the insertion slot. In addition, it is possible that: the contacts are first contacts inserted in the housing from the insertion slot by moving the front to the back of the insertion slot and whose rods The lower ends are held in the grooves formed by the ribs, and second contacts are provided, each having an upper rod extending from the rear to the front of the insertion slot and having a contact portion adapted to enter. in contact with a signal terminal on one side of the signal transfer element inserted into the housing and a lower rod extending from the rear to the front of the insertion slot, facing the upper rod so as to be able to clamp the signal transfer element in cooperation with the upper rod and having at the end at the rear of the insertion slot a connection part that can be connected to a support , and each inserted into the housing from an insertion opening located on the opposite side to the insertion slot by displacement from the rear to the front of the insertion slot, and whose lower rods are maintained in the grooves formed by the ribs, and the ends of the ribs located in front of the insertion slot are closer to the rear of the insertion slot than the ends of the lower rods of the second contacts. There is further provided an actuator movably attached to the housing, having stops configured to abut the contacts and contacting the contact portion and the signal terminal by pressing the contacts when the stops are moved. In addition, it is possible that: the contacts have an almost H-shaped contour having a connection connecting the upper rod and the lower rod, the stops each comprise a cam portion on which is formed a cam, the The cam portion is clamped by the upper rod and the lower rod located at the rear of the insertion slot relative to the delimitation formed by the coupling, and the actuator pushes the upper rod upwardly to the rear. of the insertion slot by rotating the cam portion, so that the upper rod at the front of the insertion slot with respect to the delimitation formed by the connector pivots to contact the contact portion and the signal terminal. According to the present disclosure, the ends of the ribs forming the grooves for holding the lower rods located at the front of the insertion slot are closer to the rear of the insertion slot than the end of the slot. lower housing comprising the mounting surface, on which the lower rods are mounted, located at the front of the insertion slot. Therefore, when the connection portion is for example welded to an electrode on the support, it is possible to prevent welding or flow from flowing between the lower rod and the rib, even if the solder or flow flows along of the connecting portion and flows between the lower rod and the mounting surface of the lower housing. In other words, it is possible to prevent capillary action between the lower stem and the rib. Therefore, according to the present disclosure, it is possible to prevent the flux from adhering to the contact portion of the upper rod and it is not necessary to space the elements in the spacing direction of the contacts, so that it is possible to prevent flow adhesion even if the spacing between the contacts is reduced.

    [0008] DETAILED DESCRIPTION [0023] An electrical connector 10 according to one embodiment of the present disclosure is described below. Each figure comprises a Cartesian coordinate system in which the direction of the abscissa axis, the direction of the ordinate axis and the direction of the dimension axis coincide respectively with the lateral direction, the longitudinal direction and the direction. the thickness of the electrical connector 10 and which is referred to as necessary. In addition, the direction indicated by the arrow on each axis is indicated by the plus sign and the opposite direction is indicated by the minus sign. As indicated in FIGS. 1 and 2, the electrical connector 10 comprises a virtually rectangular housing 11, multiple contacts 12 arranged in the housing 11, an actuator 13 rotatably mounted on the housing 11 and latches 14 arranged on each longitudinal side of the housing 11. The housing 11 is made of an insulating material such as a resin and disposed on a printed circuit board, for example an electronic device or the like. The housing 11 has an insertion slot 15 in which an FPC 50 can be inserted, which is an example of a plate-shaped signal transfer element. The insertion slot 15 has a large opening at the front and a small opening at the rear. In addition, the housing 11 has a lower housing 11a extending from the rear to the front of the insertion slot 15 and having a flat plate-shaped mounting surface 10 Sa extending into the direction of arrangement of the contacts 12 and on which are mounted the contacts 12. [0027] In addition, the housing 11 has ribs 11b provided on the mounting surface Sa of the lower housing 11a and extending from the rear to the front of the insertion slot so as to form grooves Za in the form of a corresponding recess 15 intended to hold the multiple contacts 12. The FPC 50 intended to be inserted into the insertion slot 15 of the housing 11 has electrodes 51 connected to the circuit. The electrodes 51 comprise first electrodes 51a provided at one end of the FPC 50 and second electrodes 51b provided at a distance from one end of the FPC 50. In addition, the FPC 50 20 has notches 52 intended to be locked in the locks. 14. The contacts 12 are each a conductor formed by a metal plate or the like and are resilient. The contacts 12 comprise first contacts 12a arranged in positions corresponding to the first electrodes 51a of the FPC 50 inserted in the housing 11. In addition, the contacts 12 comprise second contacts 12b arranged at positions corresponding to the second electrodes 51b of the FPC 50 inserted in the housing 11. When assembling the electrical connector 10 (before the attachment of the actuator 13 to the housing 11), the first contacts 12a are inserted into the housing 11 via the insertion slot 15 by moving from the front to the rear of the insertion slot 15. [0031] On the other hand, during the assembly of the electrical connector 10 (before the attachment of the actuator 13 to the housing 11), the second contacts 12b are inserted into the housing 11 via an insertion opening 16 located on the side opposite to the insertion slot 15 by moving the rear towards the front of the insertion slot 15. [0032] At this moment, first contacts 12a and the second contacts 12b are inserted into the grooves Za and the like of the housing 11 and thus fixed to the housing 11. The first contacts 12a and the second contacts 12b are arranged alternately in the longitudinal direction of the housing 11 (direction of the housing). 'Y axis). As shown in Fig. 3 (a cross-sectional view along the line AA shown in Fig. 2), the first contacts 12a each comprise a pair of rods 12a1 and 12a2 (an upper rod 12a1 and a rod lower 12a2 longer than the upper rod 12a1). The upper rod 12a1 and the lower rod 12a2 extend from the rear to the front of the insertion slot 15. The upper rod 12a1 comprises a first contact portion 12aa disposed at the end located at the before the insertion slot 15 so as to be in contact with a first electrode 51a. The lower rod 12a2 faces the upper rod 12a1 so as to be able to clamp the FPC 50 inserted into the housing 11 in cooperation with the upper rod 12a1. The lower rod 12a2 has a first connection portion 12ab welded to an electrode of the printed circuit board, for example an electronic device or the like, at the end located at the front of the insertion slot 15. 12ab first connection part is fully discovered except for the connection surface. In addition, the lower rod 12a2 comprises a long lower rod 12a2 _a mounted on the mounting surface Sa of the lower housing 11a and extending from the rear to the front of the insertion slot 15. The Long lower rod 12a2 _a is held in a groove Za formed by the ribs 11b. In addition, the lower rod 12a2 comprises a curvature 12a2 _b disposed between the end of the long lower rod 12a2 _a located at the front of the insertion slot 15 and the first connection portion 12ab and whose surface facing the mounting surface Sa is bent towards the upper rod 12a1 to form a gap with respect to the mounting surface Sa. The first contacts 12a described above each comprise a pillar 12a2 connecting the upper rod 12a1 and the lower rod 12a2. Due to the connection formed by the pillar 12a3 between the upper rod 12a1 and the lower rod 12a2, the first contacts 12a have a substantially H-shaped contour. The pair of rods (the upper rod 12a1 and the rod bottom 12a2) located on one side of each first contact 12a with respect to the delimitation formed by the pillar 12a3, is disposed on the inner periphery of the insertion slot 15 of the housing 11 and the first contact portion 12aa is partially projecting. In addition, the pair of rods (the upper rod 12a1 and the lower rod 12a2) 20 located on the other side of each first contact 12a relative to the delimitation formed by the pillar 12a3, is disposed on the side of the housing 11 closer to the insertion opening 16. There, the upper rod 12a1 protrudes from the housing 11. [0041] A cam portion 13c, of ellipsoidal cross-section, of the actuator 13 described below is positioned between the pair of rods (the upper rod 12a1 and the lower rod 12a2) located on the other side of each first contact 12a. As the pair of rods located on the other side of each first contact 12a maintains a cam portion 13c of the actuator 13, the actuator 13 can pivot relative to the housing 11. Thus, the part of cam 13c can pivot about the axis 13d in accordance with the rotation of the actuator 13. In addition, the upper rod 12a1 located on the other side of each first contact 12a is inserted into a slot 13e formed directly above of the cam portion 13c. Then, as shown in Figure 4, the second contacts 12b each comprise a pair of rods 12b1 and 12b2 (an upper rod 12b1 and a lower rod 12b2 longer than the upper rod 12b1). The upper rod 12b1 and the lower rod 12b2 extend from the rear to the front of the insertion slot 15. The upper rod 12b1 has a second contact portion 12ba disposed at the end located at the before the insertion slot 15 so as to be able to come into contact with a second electrode 5b. The lower rod 12b2 faces the upper rod 12b1 so as to be able to grip the FPC 50 inserted into the housing 11 in cooperation with the upper rod 12b1. The lower rod 12b2 is held in a groove Za formed by the ribs 11b. In addition, the lower rod 12b2 comprises a second connection portion 12bb soldered to an electrode of the printed circuit board, for example an electronic device or the like, at the end closer to the opening of the insertion 16 of the housing 11 (at the end located at the rear of the insertion slot 15). The second contacts 12b described above each comprise a pillar 12b3 connecting the upper rod 12b1 and the lower rod 12b2. Due to the connection formed by the pillar 12b3 between the upper rod 12b1 and the lower rod 12b2, the second contacts 12b have an almost H-shaped contour. The pair of rods (the upper rod 12b1 and the lower rod 12b2) located on one side of each second contact 12b with respect to the delimitation formed by the pillar 12b3, is disposed on the inner periphery of the insertion slot 15 of the housing 11 and the second contact portion 12ba partially projects. In addition, the pair of rods (the upper rod 12b1 and the lower rod 12b2) located on the other side of each second contact 12b with respect to the delimitation 5 formed by the pillar 12a3, is disposed on the side of the housing 11 closer to the insertion opening 16. In addition, the upper rod 12b1 protrudes from the housing 11. As for the first contacts 12a, a cam portion 13c of the actuator 13 is disposed between this pair of rods ( the upper rod 12b1 and the lower rod 12b2). As a result, the cam portion 13c of the actuator 13 is held by the pair of rods on the other side of the second contact 12b. As shown in Figures 1 and 2, the actuator 13 is for example disposed on the side of the housing 11 closer to the insertion opening 16 (the side facing the insertion slot 15). The actuator 13 has an actuating portion 13a extending in the longitudinal direction of the housing 11 (the direction of the ordinate axis). In addition, as shown in FIG. 2, the actuator 13 comprises abutments 13b disposed at each longitudinal end of the actuating portion 13a. The actuating portion 13a is arranged so that its longitudinal direction coincides almost with the longitudinal direction of the housing 11. The stops 13b are housed in recesses formed in the lateral ends of the housing 11. Therefore, the actuator 13 is fixed to the housing 11 and the recesses serve to retain the housing 11 for the case where the actuator 13 would be subjected to an unforeseen force. In addition, as indicated in FIGS. 3 and 4, the actuator 13 is integrally provided with multiple cam portions 13c extending in one piece from the stops 13b via the slot 13e, actuating the first contacts 12a and second contacts 12b and having a cross section having short and long orthogonal sides. As described above, the cam portions 13c are held by the pair of rods (the upper rod 12a1 and the lower rod 12a2) located on the other side of the first contacts 12a and the pair of rods (the upper rod 12b1 and the lower rod 12b2) located on the other side of the second contacts 12b. In addition, the cam portions 13c are configured to also be able to come into contact with the latches 14. Like the first contacts 12a and the second contacts 12b, the latches 14 each comprise a pair of rods 14a. and 14b (an upper rod 14a and a lower rod 14b longer than the upper rod 14a), as shown in Figure 5 (a cross-sectional view along the line CC shown in Figure 2). In addition, the latches 14 each comprise a pillar 14c connecting the upper rod 14a and the lower rod 14b. Due to the connection formed by the pillar 14c between the upper rod 14a and the lower rod 14b, the latches 14 have a substantially H-shaped contour such as the first contacts 12a and second contacts 12b. The pair of rods located on one side of each latch 14 relative to the delimitation formed by the pillar 14c, is disposed on the inner periphery of the insertion slot 15 of the housing 11. The upper rod 14a of the pair of stems located on one side of each latch 14 is provided at its end with a claw 14d which forms a protrusion intended to be locked in a notch 52 of the FPC 50. [0056] In addition, a cam portion 13c of the actuator 13 is disposed between the pair of rods (the upper rod 14a and the lower rod 14b) located on the other side of each latch 14 relative to the delimitation formed by the pillar 14c (the side closer to the insertion opening 16). Therefore, the cam portions 13c are also held by the pair of rods located on the other side of the latches 14. [0057] The connection operation of the electrical connector 10 having the elements described above is described below. . It is assumed that at least the first connection portions 12ab and second connection portions 12bb are already soldered to electrodes on the printed circuit board in the electrical connector 10. In the electrical connector 10, when the actuator 13 is for example open (the actuator 13 is almost perpendicular to the insertion direction of the FPC 50), as shown in Figures 3 to 5, the pairs of rods of the first contacts 12a, second contacts 12b and latches 14 enclose each a cam portion 13c at two points forming a short side in a cross section. Therefore, the distance between each pair of rods of the first contacts 12a, second contacts 12b and latches 14 is greater than when the actuator 13 is locked (larger than when the actuator 13 is almost horizontal by report to the FPC 50 integration directorate). At this time, the distance between the pair of rods located on one side of each first contact 12a and the distance between the pair of rods located on one side of each second contact 12b is greater than when the actuator 13 is locked. Therefore, the contacts 12 do not apply contact pressure or only a marginal contact pressure on the FPC 50 and the user can insert the FPC 50 in the insertion slot 15 of the housing 11 in order to place the FPC 50 in the housing 11 (displacement in the + x direction). When the operator pivots the actuator 13 open, the actuator 13 becomes almost horizontal with respect to the insertion direction of the FPC 50, that is to say, it is locked as shown in the figures 6A to 6C. Upon rotation of the actuator 13 between the open state and the lock state, the cam portions 13c of the actuator 13 pivot about the axis 13d. When the actuator 13 is locked as shown in Figure 6B (a cross-sectional view along the line DD shown in Figure 6A), the pair of rods (the upper rod 12a1 and the lower rod 12a2) located on the other side of each first contact 12a clamps the cam portion 13c at two points forming a long side in a cross section. Therefore, the upper rod 12a1 located on the other side of each first contact 12a is pushed upwards. Similarly, when the actuator 13 is locked as shown in Figure 6C (a cross-sectional view along the line EE shown in Figure 6A), the pair of rods (the upper rod 12b1 and the lower rod 12b2) located on the other side of each second contact 12b clamps the cam portion 13c at two points forming a long side in a cross section. Therefore, the upper rod 12b1 located on the other side of each second contact 12b is pushed upwards. Then, the upper rod 12a1 located on one side of each first contact 12a and the upper rod 12b1 located on one side of each second contact 12b are pivoted. At this time, the distance between the pair of rods located on one side of each first contact 12a and the distance between the pair of rods located on one side of each second contact 12b are smaller than when the actuator 13 is open. Therefore, the first contact portion 12aa and the first electrode 51a as well as the second contact portion 12ba and the second electrode 5b come into contact (the contacts 12 apply a contact pressure on the FPC 50). In addition, when the actuator 13 is locked, the pair of rods (the upper rod 14a and the lower rod 14b) located on the other side of each latch 14 also encloses the cam portion 13c in two points forming a long side in a cross section. Then, the upper rod 14a located on one side of each latch 14 pivots.
    [0009] At this time, the distance between the pair of rods (the upper rod 14a and the lower rod 14b) located on one side of each latch 14 is smaller than when the actuator 13 is open. Consequently, the claw 14d provided on the upper rod 14a located on one side of each latch 14 is locked in the notch 52. Therefore, the FPC 50 is held in place inside the housing 11 and its displacement in the direction -x which corresponds to the withdrawal direction of the FPC 50 is limited, so that the FPC 50 is fully housed in the housing 11 and the first electrodes 51a and second electrodes 5 lb of the FPC 50 and the electrodes of the card circuit board corresponding to these electrodes are connected. The effect of the present disclosure on the electrical connector 10 described above is described below. As shown in fig. 7 (a cross-sectional view along the F-F line shown in Fig. 2) and in fig. 8 (a cross-sectional view along the line GG shown in Fig. 2), the bend 12a2b extends beyond the end 11aa of the lower housing 11a, so that the first connecting portion 12ab is located away from the end 11aa of the lower housing 11a located at the front of the insertion slot 15. [0067] Thus, the first connecting portion 12ab can be arranged as far as possible from the end 11aa of the lower housing 11a. In addition, the first connection portion 12ab can be fully discovered. Therefore, when the first connection portion 12ab is soldered, for example, to an electrode on the printed circuit board, it is possible to prevent the solder or flux from entering between the long lower rod 12a2a and the mounting surface Sa of the lower housing 11a. It is therefore possible to prevent welding or flux from flowing between the long lower rod 12a2a and the inner wall surfaces of the ribs 11b. Therefore, it is possible to prevent the flux from adhering to the first contact portion 12aa of the upper rod 12a1. Just like the first connection portion 12ab, the second connection portion 12bb is here also disposed at a distance from the end 12c of the housing 11 where the insertion opening 16 is located. In addition, the second part of 12bb connection is also fully discovered. Thus, when the second connection portion 12bb is soldered, for example, to an electrode on the printed circuit board, it is possible to prevent solder or flux from flowing between the lower rod 12b2 and the inner wall surfaces of the ribs 11b. Therefore, it is possible to prevent the flux from adhering to the second contact portion 12ba of the upper rod 12b1. In addition, in the electrical connector 10, the end llba of each rib 11b located in front of the insertion slot 15 is closer to the rear of the insertion slot 15 than the point of insertion. Ta junction between the long lower rod 12a2 _a and the curvature 12a2 b, as shown in FIG. 7. [0071] In the upstream part of the Ta junction point (the part closer to the front of the insertion slot 15), the surface of the curvature 12a2 _b facing the mounting surface Sa is here curved towards the upper rod 12a1. Therefore, the distance between the curvature 12a2 _b and the mounting surface Sa is greater than the distance between the long lower rod 12a2 _a and the mounting surface Sa. In addition, the entire surface of the curvature 12a2 _b is discovery. Therefore, when the first connection portion 12ab is soldered, for example, to an electrode on the printed circuit board, it is possible to prevent the solder or flux adhering to the first connection portion 12ab from penetrating between the long lower rod 12a2a and the mounting surface Sa of the lower housing 11a. It is therefore possible to prevent welding or flux from flowing between the long lower rod 12a2 _a and the mounting surface Sa. Therefore, it is possible to prevent the flux from adhering to the first contact portion 12aa of the upper stem 12al. In addition, in the electrical connector 10, the ribs 1lb forming the grooves Za for holding the lower rods 12a2 and 12b2 are provided on the mounting surface Sa of the lower housing 11a on which are mounted the lower rods 12a2 and 12b2 and are formed integrally with the housing 11. Here, the end llba of each rib 11b located in front of the insertion slot 15 is closer to the rear of the slot of 15 insertion of the end 11aa of the lower housing 11 located at the front of the insertion slot 15. Therefore, the part of the long lower rod 12a2 _a discovered from the end llba faces only Thus, when the first connecting portion 12b is soldered, for example, to an electrode on the printed circuit board, it is possible to prevent solder or flow from flowing between the long lower stem 12a2 _a and the surface Sa mounting and between the long lower rod 12a2 _a and the inner wall surfaces of the ribs 11b. In other words, it is possible to prevent capillary action between the long lower rod 12a2a and the inner wall surfaces of the ribs 11b. Therefore, it is possible to prevent welding or flux from adhering to the first contact portion 12aa of the upper rod 12a1. In addition, the end llba of each rib 11b located at the front of the insertion slot 15 is closer to the rear of the insertion slot 15 than the end 12b2 _s of the lower rod. 12b2 of each second contact 12b, as shown in FIG. 8. Here, the ribs 11b should only be able to hold in place the ends of the lower rods 12a2 and 12b2 in the direction in which the contacts 12a and 12b are disposed. Therefore, the end 12b2 _s of each lower rod 12b2 can be found from the end llba of each rib 11b. As mentioned above, the end llba of each rib llb may be disposed closer to the rear of the insertion slot 15 since the end 12b2 _s of each lower rod 12b2 is uncovered. . Therefore, when the first connection portion 12ab is soldered, for example, to an electrode on the printed circuit board, the effect of preventing solder or flow from flowing between the lower rod 12b2 and the inner wall surfaces ribs 11b is reinforced. As described above, in the electrical connector 10 according to this embodiment, the end llba of each rib 1 lb located at the front of the insertion slot 15 is closer to the back of the insertion slot 15 that the end 11aa of the lower housing 11a located at the front of the insertion slot 15. [0080] Therefore, when the first connecting portion 12ab is welded, for example, to an electrode on the printed circuit board, it is possible to prevent welding or flux from flowing between the long lower rod 12a2 _a and the inner wall surfaces of the ribs 11b, even if, for whatever reason, the weld or the flow flows between the long lower rod 12a2 _a and the mounting surface Sa of the lower housing 11a. Therefore, the electrical connector 10 according to this embodiment can prevent the flow from adhering to the first contact portion 12aa of the upper rod 12al. In addition, in the electrical connector 10 according to this embodiment, the second connection portion 12bb is, like the connection portion 12ab, also disposed remotely from the end 11c of the housing 11 where is located insert opening 16. In addition, the second connecting portion 12bb is also fully discovered. Thus, when the second connection portion 12bb is soldered, for example, to an electrode on the printed circuit board, it is possible to prevent solder or flux from flowing between the lower rod 12b2 and the inner wall surfaces of the ribs 11b. Therefore, it is possible to prevent the flux from adhering to the second contact portion 12ba of the upper rod 12b1. In addition, in the electrical connector 10 according to this embodiment, it is not necessary to space the elements in the direction of arrangement of the contacts 12a and 12b. Therefore, the prevention of flow adhesion as described above can be achieved even if the spacing of the contacts 12a and 12b is reduced. In addition, in the electrical connector 10 according to this embodiment, it is possible to prevent welding or flux from flowing between the long lower rod 12a2 _a and the inner wall surfaces of the ribs 11b and between the rod. bottom 12b2 and the inner wall surfaces of the ribs 11b, so that it is not necessary to form through holes at the lower housing 11a to discharge the solder or flux. In addition, it is not necessary to provide circuit-free areas on the printed circuit board on which the electrical connector 10 is mounted. Therefore, the electrical connector 10 according to this embodiment allows efficient use of the card. printed circuit board. An embodiment of the present disclosure has been described above. However, the present disclosure is not limited to the embodiment described above, but permits various modifications and uses. For example, in the electrical connector 10 according to the embodiment described above, the actuator 13 pivots relative to the housing 11. This is not restrictive. The actuator can also be of the sliding type relative to the housing 11. In such a case, the actuator is fixed to the housing 11 so as to slide from a point closer to the insertion slot 15 to a point closer to the insertion opening 16 and the point closer to the insertion opening 16 at the point closer to the insertion slot 15. When the above actuator is moved up At the point closer to the insertion slot 15, the actuator abuts and presses on the upper rod 12a1 located on one side of each first contact 12a with respect to the delimitation formed by the pillar 12a3 and on the upper rod 12b1 located on one side of each second contact 12b with respect to the delimitation formed by the pillar 12b3. Therefore, the upper rod 12a1 located on one side of each first contact 12a and the upper rod 12b1 located on one side of each second contact 12b are pivoted. At this time, the distance between the pair of rods located on one side of each first contact 12a and the distance between the pair of rods located on one side of each second contact 12b is smaller than when the actuator is moved to the point closer to the insertion aperture 16. Therefore, the first contact portion 12aa and the first electrode 51a come into contact, as well as the second contact portion 12ba and the second electrode 5b. On the other hand, when the actuator above is moved to the nearest point of the insertion opening 16, the actuator is no longer in abutment against the upper rod 12a1 located on the one side of each first contact 12a with respect to the delimitation formed by the pillar 12a3 and the upper rod 12b1 located on one side of each second contact 12b with respect to the delimitation formed by the pillar 12b3. Therefore, the upper rod 12a1 located on one side of each first contact 12a and the rod 12b1 located on one side of each second contact 12b return to a being in which they are no longer under pressure. At this time, the distance between the pair of rods located on one side of each first contact 12a and the distance between the pair of rods located on one side of each second contact 12b is greater than when the actuator is moved to the nearest point of the insertion slot 15. Therefore, the first contact portion 12aa and the second electrode 51a and the second contact portion 12ba and the second electrode 51b are no longer in contact (or in contact lightweight). As mentioned above, the electrical connector 10 may comprise an actuator sliding relative to the housing 11 instead of the actuator 13 pivoting relative to the housing 11. In addition, in the electrical connector 10 according to the embodiment described above, the end 12b2 _s of the lower rod 12b2 of each second contact 12b is discovered from the end llba of each rib 11b. This is not restrictive. For example, the end 12b2 s of each lower rod 12b2 may be aligned with the end llba of each rib 11b or may be disposed closer to the back of the insertion slot 15 than the end llba of each rib 11b. In addition, the electrical connector 10 according to the embodiment described above includes the latches 14. This is not restrictive. In other words, the electrical connector 10 according to the embodiment described above may not include the latches 14.
