The insulator A is manufactured by known injection molding or the like, and requires heat resistance, moldability, and low cost as a material. The connecting member is also an electrically insulating plastic, and is made of the same material as the insulator A.
The receptacle contact is mainly composed of three parts: a contact part that contacts the pin contact 62 of the pin connector 60, a fixing part that is held and fixed to the insulator A, and a connection part that is pressed into the substrate.

The contact body is held and fixed by the projection of the contact body being hooked on the hooked portion of the connector. A groove is provided between the connecting member and the contact body in which the receptacle contact is integrated on the side opposite to the projecting side. This groove is a portion where the tongue piece of the shield plate A catches, and is for preventing the shield plate A from shifting in the width direction.

The shield plate A will be described. The shield plate A is made of metal, is formed by a known technique such as press working, and has a substantially L-shape. The shield plate A
On one of the free ends, there is provided a locking piece A fitted into the engaging portion A of the block. The locking piece A is for preventing the shield plate A from floating by engaging with the engaging portion A. The locking piece A50 protrudes. On the other free end side, a required number of terminals that are pressed into the substrate project. A projection is provided at the tip of the terminal.
This is a portion to be fitted into the locking portion, and fixes the shield plate B by being fitted.

[0032] A hook portion that can be engaged with a hook portion of the coupling tool is provided from a portion that is turned over above the terminal. In addition, a required number of tongue pieces cut and raised in the same manner as the hook portions are provided between the folded portion and the concave portion. This tongue engages with a groove formed between the connecting member and the contact body, thereby forming the shield plate A.
In order to prevent the displacement in the width direction. On the locking piece A side, there is provided a contact portion which is brought into contact with the pin contact 62 on the outer side in the width direction of the pin connector 60 and grounds. This contact portion is curved outward so that it can contact the pin contact 62. In addition, a concave portion is provided near the contact portion at a position where the convex portion of the block can be fitted.

Next, the shield plate B will be described. The shield plate B is made of metal, is formed by a known press working or the like, and has a flat plate shape. The shield plate B
On one of the free ends, there is provided a locking piece B fitted into the engaging portion A of the block. This locking piece B is also for preventing the shield plate B from floating by engaging with the engaging portion A. On the other free end side, a required number of locking portions for engaging with the terminals of the shield plate A are provided. The shield plate B is fixed by hooking the protrusions of the terminals of the shield plate A to the locking portions.

On the locking piece B side, there is provided a contact portion which is brought into contact with a pin contact 62 on the outer side in the width direction of the pin connector 60 to be grounded. This contact portion is curved outward so that it can contact the pin contact 62. In addition, a concave portion is provided near the contact portion at a position where the convex portion of the block can be fitted.

[0035]

According to the present invention, the following remarkable effects can be obtained by adopting the above structure. (1) When the cover 18 is slid, the pressing portion 2 of the cover 18
The push-on push-pull system in which the lock piece 20 can be removed can be achieved simply by the step 6 riding on the step 28 of the lock piece 20. (2) Since the lock connector 20 is provided on the cable connector 10 and the lock receiving member 50 is mounted on the shroud 40 by a push-on push-pull system, the cable connector 10 can be easily mounted on the shroud 40. . (3) The cable connector 10 can be attached and detached only by sliding the cover 18 of the cable connector 10, so that the space does not become larger than before. (4) Although the lock piece 20 of the cable connector 10 has a spring property, even when the lock piece 20 is permanently deformed,
Since the shield plate 16 is provided with a spring piece, the lock piece 2
0 always returns to the original position. (5) By providing the convex portion 37 on the socket connector 12 of the cable connector 10 and providing the groove 53 on the lock receiving member 50, the cable connector 10 is prevented from being inserted in the wrong direction. (6) By providing a plurality of locking holes 44 on the side walls on both sides in the width direction of the shroud 40, it is possible to easily cope with a difference in the number of cores of the cable connector 10. (7) By color-coding the lock receiving member 50, the insertion position of the cable connector 10 having a different number of cores can be easily recognized, and erroneous insertion is prevented.
