  Thus, since the slider 41 positions the flexible cables 81a and 81b and sandwiches the flexible cables 81a and 81b with the slider cover 51, the connection loss between the cable ends of the flexible cables 81a and 81b can be prevented, and the flexible cables 81a and 81b can be prevented. The holding force of 81b can be improved.

  Next, the relay connector of the joint connector according to the embodiment of the present invention will be described in detail with reference to FIGS. FIG. 5 is a perspective view of the relay connector of the joint connector according to the embodiment of the present invention. FIG. 6A is a front view of the relay connector according to the embodiment of the present invention. FIG.6 (b) is BB sectional drawing of the relay connector which concerns on embodiment of this invention. Fig.7 (a) is a perspective view which shows the joint terminal of the joint connector which concerns on embodiment of this invention. FIG.7 (b) is a front view which shows the joint terminal of the joint connector which concerns on embodiment of this invention.

  As shown in FIGS. 5 to 7, the relay connector 21 is formed in a cylindrical shape with a material such as synthetic resin, and the connector main body 61 that fits into the connector housing 31 and the cable ends of the flexible cables 81 a and 81 b are connected to each other. And a joint terminal 71 for connecting the two.

  The connector main body 61 is provided on both sides of the connector main body 61 and is connected to the slider support portion fitting portion (fitting portion) 62 into which the connector housing 31 is fitted, and the joint terminal 71 is connected to the slider support portion fitting portion 62. A plurality of joint terminal insertion portions 63, a first lock protrusion 64 that engages with the lock portion 34 of the connector housing 31, and a second lock protrusion 65 are provided.

  As shown in FIG. 6B, the slider support part fitting part 62 is fitted to the slider support part 33 of the terminal support connectors 11a and 11b in a state where the terminal support connectors 11a and 11b are fitted to the connector main body 61. . Specifically, the slider support part fitting part 62 is fitted to the slider support part 33 of the terminal support connectors 11a and 11b via the packing 85 provided with the cable insertion holes 32 of the terminal support connectors 11a and 11b ( (See FIG. 10 described later).

  As described above, the connector main body 61 of the relay connector 21 is formed with the slider support portion fitting portions 62 into which the connector housing 31 is fitted on both sides, so that the connector housing 31 serves as the cable ends of the flexible cables 81a and 81b. The relay connector can be fitted in a supported state. For this reason, it becomes easy to insert the flexible cables 81 a and 81 b into the relay connector 21. Therefore, the fitting operation can be facilitated and the holding force of the flexible cables 81a and 81b can be improved.

  The joint terminal insertion part 63 is provided in communication with the slider support part fitting part 62. When the joint terminal insertion part 63 accommodates the joint terminal 71, the joint terminal 71 is accommodated at the approximate center of the terminal main body 72.

When the terminal support connectors 11a and 11b and the relay connector 21 are fitted, the lock portion 34 gets over the first lock protrusion 64 and is provided between the first lock protrusion 64 and the second lock protrusion 65. By inserting the locking portion 34 of the connector housing 31 between the protrusions 66, the terminal support connectors 11a and 11b and the relay connector 21 are locked (locked).

  Further, the lock portion 34 cannot get over the second lock protrusion 65, and the lock portion 34 is locked between the lock protrusions 66. In addition, since the lock portion 34 cannot get over the second lock protrusion 65, when the terminal support connectors 11a, 11ba, 11b and the relay connector 21 are fitted, the relay connector 21 is more terminally supported than the normal fitting position. Insertion into the connectors 11a and 11b side (one side terminal support connector 11a is the other side terminal support connector 11b side, and the other side terminal support connector 11b is the one side terminal support connector 11a side) can be prevented.

  The first lock protrusion 64 is a member (lock part) having a predetermined elasticity so as to bend and deform toward the flexible cables 81a and 81b so that the lock part 34 can get over and be locked between the lock protrusions 66. 34 may be formed of a member having elasticity enough to be able to get over the first lock protrusion 64 and be locked between the lock protrusions 66; a material such as a synthetic resin.

  Thus, the 1st lock projection 64 and the 2nd lock projection 65 of relay connector 21 engage with lock part 34 provided in terminal support connectors 11a and 11b. For this reason, it is possible to prevent the fitted terminal support connectors 11a and 11b and the relay connector 21 from being easily detached, and to improve the holding force of the flexible cables 81a and 81b.

  In addition, the relay connector 21 is formed with a rail portion 69 that fits with the guide portions 36 of the terminal support connectors 11a and 11b. When the relay connector 21 is fitted into the terminal support connectors 11a and 11b, the rail portion 69 is guided to the inside of the terminal support connectors 11a and 11b by sliding on the rail portion 69, and the terminal support connectors 11a and 11b. It is held at the normal mating position.

  As shown in FIG. 7, the joint terminal 71 is provided in a pair with the terminal main body 72 accommodated in the joint terminal insertion portion 63 of the connector main body 61 and the terminal main body 72 interposed therebetween, and has followability to the flexible cables 81 a and 81 b. And a sandwiching contact portion 73.

  The terminal main body 72 connects a pair of sandwiching contact portions 73, and the sandwiching contact portion 73 is in contact with the sandwiching contact portion 73 a that is in contact with or close to the upper surface side of the relay connector 21 and the lower surface side of the relay connector 21. The holding contact portion 73b is inclined at an angle. The sandwiching contact portion 73a and the sandwiching contact portion 73b are symmetric at the center of the terminal body 72, and the space between the sandwiching contact portion 73a and the sandwiching contact portion 73b is directed from the terminal body 72 toward the tip of the sandwiching contact portion 73. It is narrower.

  When the terminal support connectors 11a and 11b are fitted to the relay connector 21, the slider 41 that supports the cable terminal of the flexible cable 18 is held between the sandwiching contact portion 73a and the sandwiching contact portion 73b.

  Thus, since the slider 41 that supports the cable end of the flexible cable 18 is held between the sandwiching contact portion 73a and the sandwiching contact portion 73b, the conductor portions of the flexible cables 81a and 81b are unlikely to be displaced. Connection loss can be prevented.

  Further, the contact load between the terminal body 72 and the flexible cables 81a and 81b can be adjusted by configuring the slider 41 and the slider cover 51 with resin and changing the resin thickness. In other words, when the sandwiching contact portion 73a and the sandwiching contact portion 73b are formed of an elastic member having a predetermined displacement, the sandwiching contact portion is changed by changing the resin thickness of the slider 41 and the slider cover 51. It is possible to adjust the amount of displacement of the terminal main body 72 at the stage of examining the contact load by giving a width to the amount of displacement between 73a and the sandwiching contact portion 73b.

  By changing the resin thickness of the slider 41, variations in the thickness of the flexible cables 81a and 81b are abundant, the width of the displacement amount of the terminal is increased, and the contact load can be finely adjusted.

  Next, with reference to FIG. 8 to FIG. 10, a case where the relay connector is fitted to the terminal support connector according to the embodiment of the present invention will be described.

  The slider 41 sandwiches the flexible cables 81 a and 81 b with the slider cover 51 with the flexible cables 81 a and 81 b positioned, and the slider cover 51 is supported by the slider support portion 33 of the connector housing 31.

  When the slider cover 51 is supported by the slider support portion 33 of the connector housing 31, the cable ends of the flexible cables 81a and 81b protrude from the slider support portion 33 together with the tip end side of the slider (see FIG. 3A).

  Then, the terminal support connectors 11 a and 11 b are fitted from both sides of the relay connector 21 with the cable ends of the flexible cables 81 a and 81 b protruding from the slider support portion 33.

  The relay connector 21 is provided with a joint terminal 71 for connecting the cable terminals of the flexible cables 81 a and 81 b supported by the connector housing 31. Therefore, when the terminal support connectors 11a and 11b are respectively inserted from both sides of the relay connector 21, the terminal support connectors 11a and 11b protruding from the slider support portion 33 are sandwiched between the sandwich contact portion 73a and the sandwich contact portion 73b of the joint terminal 71. Thus, the terminal support connectors 11a and 11b are electrically connected to each other.

  When the terminal support connectors 11a, 11b and the relay connector 21 are fitted in the normal fitting position, the lock portions of the terminal support connectors 11a, 11b get over the first lock protrusion 64, and the first lock protrusion 64 and the second lock Locking is made between the locking protrusions 66 provided between the protrusions 65.
