Description

  The present invention relates to a socket housing of a socket connector and a base housing of a base connector used in combination with the socket connector.

  The socket connector includes a socket housing, a plurality of socket contacts, and a plurality of cables respectively connected to the plurality of socket contacts. When manufacturing the socket connector, the socket contact and the cable are connected in advance to form an assembly, and the socket contact and cable assembly is arranged in the socket contact arrangement portion of the socket housing to manufacture the socket connector. To do.

However, at the time of manufacturing, the socket contact may not be sufficiently inserted into the socket contact placement portion (half-insertion, incomplete insertion), and the socket contact may not be placed at a normal position (manufacturing failure). In this case, in the combined state of the socket connector and the base connector, the socket contact does not completely contact the base contact. Therefore, the function of the connector may not be exhibited.

  The lock portion 14A includes a hook portion 31 extending in the fourth direction D4, a force point portion 32 extending in the fifth direction D5, and a fulcrum located between the hook portion 31 and the force point portion 32 and connected to the side wall of the socket housing 10. Unit 33. The lock portion 14 </ b> A is configured so that the hook portion 31 and the force point portion 32 can rotate around the fulcrum portion 33. When the force point portion 32 is pressed inward in the third direction D3, the hook portion 31 opens outward in the third direction D3 with the fulcrum portion 33 as the center. The front end portion of the hook portion 31 in the fourth direction D4 forms an engaging protrusion that protrudes inward in the third direction D3.

  The base contact 80 and the socket contact 50 can be shared by the first and second embodiments having different fitting directions. Specifically, as described above, in the base contact 80, the front end 82a and the upper end 82b of the socket side connection portion 82 are both rounded. Further, in the socket contact 50, the front end 53a and the lower end 53b of the socket contact holding piece 53 are rounded. Therefore, the base contact 80 and the socket contact 50 can be applied to both the first embodiment fitted in the first direction D1 and the fourth embodiment fitted in the fourth direction D4.

  Note that the configuration of the base contact 80 and the socket contact 50 for the first embodiment and the base contact 80 and the socket contact 50 for the second embodiment are within a range that does not significantly affect the functions of the base contact 80 and the socket contact 50. The configuration can be made different.

FIG. 26 is a perspective view of the socket connector 2A according to the third embodiment of the present invention combined with the base connector 3A as viewed from the socket connector 2A (corresponding to FIG. 19). 27 is a perspective view of the state shown in FIG. 26 viewed from the base connector 3A side (corresponding to FIG. 20). FIG. 28 is a perspective view of the base connector 3A as viewed from above (corresponding to FIG. 21). FIG. 29 is a side view of the base connector 3A (corresponding to FIG. 22). FIG. 30 is a plan view of the socket connector 2A (corresponding to FIG. 23). FIG. 31 is a rear view of the socket connector 2A (corresponding to FIG. 24). FIG. 32 is a perspective view of the socket connector 2A viewed from below (corresponding to FIG. 25). FIG. 33 is a perspective view of the reinforcing tab 7 in the third embodiment.

  The third embodiment mainly differs from the second embodiment in the number of base contacts 80 and socket contacts 50. However, the description of the second embodiment is incorporated as appropriate for points that are not particularly described in the third embodiment. The third embodiment also has the same effect as the second embodiment.

  In the second embodiment, there are 16 base contacts 80 in the base connector 3A and 16 socket contacts 50 in the socket connector 2A. On the other hand, in the third embodiment, there are eight base contacts 80 in the base connector 3A and eight socket contacts 50 in the socket connector 2A. Specifically, in the third embodiment, the base contact group 81a including the eight base contacts 80a, the socket contact group 51a including the eight socket contacts 50a, and the cable 5a coupled thereto are used in the second embodiment. I do not have.

  In the third embodiment, as shown in FIG. 28, the base housing base 61 of the base housing 60 holds a holding member 72 (described later) on the base end side of the reinforcing tab 7 so as to sandwich and hold it. 69. The fixing member holding portion 69 is recessed so as to extend from the lower portion of the base housing base portion 61 to the inside in the third direction D3.

  As shown in FIGS. 28 and 33, the reinforcing tab 7 includes a fixed piece portion 71 and a held piece portion 72 and has a flat plate shape. The fixed piece 71 is coupled by soldering when the base connector 3A is fixed to a mounting surface (not shown) of the circuit board. The held piece 72 is sandwiched and held by the fixing member holding portion 69 of the base housing 60. Thereby, the reinforcing tab 7 is coupled to the base housing 60 and fixes the base housing 60 to the mounting surface of the circuit board.

  Compared with the power point portion 32 of the second embodiment, the power point portion 32 of the third embodiment protrudes outside the third direction D3 and has a shape that is easy to press.

The embodiments of the socket housing and the base housing of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and can be appropriately changed.
For example, in the first and second embodiments described above, the socket contact group has two rows and the base contact group has two rows, but this is not limitative. The socket contact group and the base contact group may be one row as in the third embodiment, or may be three or more rows.
In the embodiment, in the state where the socket contact 50 is arranged at the normal position of the socket contact arrangement portion 20, the end of the socket contact 50 on the fifth direction D5 side is arranged in the viewing window 25. Although configured, it is not limited to this. Other elements relating to the socket contact 50 can also be arranged in the viewing window 25.
