[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a connector in which wrinkles are not formed on an outer surface of a protective cover when ultrasonically welding a resin cover and a protective cover of the connector. is there.

[0002]

2. Description of the Related Art A conventional connector of this type will be described with reference to FIG. In the figure, reference numeral 1 denotes a connector. The connector 1 has a molded body 3 in which contact terminals 2, 2,... Are fitted inside a shield case 4, and a front end portion of the shield case 4 (the left end in the figure). Side) to the mating connector (not shown)
And a surface other than the fitting portion 4a and the rear end surface of the shield case 4 is covered with a resin cover 5; The protective cover 6 made of resin is joined to the open part of the rear end face, and the joint part 7 is ultrasonically welded to form the connector 1.

[0003]

SUMMARY OF THE INVENTION A protective cover is joined to an open portion of a rear end surface of a resin cover for covering the above connector,
When the joint portion is ultrasonically welded, the shield case and the protective cover are in close contact with each other, so that wrinkles are generated on the outer surface of the shield case during the welding. In such a case, the appearance of the protective cover is hindered.

Therefore, when the resin cover of the connector and the protective cover are ultrasonically welded, there arises a technical problem to be solved in order to prevent wrinkles from being formed on the outer surface of the protective cover. Aims to solve the problem.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed to achieve the above object, and a metal shield case is fitted to a mold body in which contact terminals are fitted, and a front part is mated with a mating connector. Forming a fitting portion for fitting into, furthermore, the surface of the shield case except for the rear end surface at the rear portion of the fitting portion is covered with a resin cover,
Further, in a connector formed by ultrasonically welding a protective cover to the rear end surface of the resin cover, a space is formed between the protective cover and the shield case, and a dowel is provided in the shield case. Are provided in the space.

[0006]

According to the present invention, a predetermined space is formed between the shield case and the protective cover, and a dowel provided on the shield case is projected from the space to form the space between the protective cover and the shield case. Therefore, when the protective cover and the resin cover are ultrasonically welded to each other, wrinkles on the outer surface of the protective cover as in the related art do not occur.

Further, since the shield case and the protective cover are in contact with each other by the dowels, it is possible to prevent the shield case from moving in the direction of the protective cover when inserting the socket connector into the plug connector.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to FIGS. Incidentally, for convenience of explanation, a configuration belonging to the related art will be described at the same time. In the figure, 10 is a connector,
The connector 10 has a shield case 14 in which a molded body 13 in which guide pins 11, 11 and contact terminals 12, 12,... Are fitted is fitted, and the shield case 14 has a front end (in FIG. (A left side) into a mating opening of a mating connector (not shown).
Further, an outer surface of the shield case 14 except for a rear end surface, which is a rear portion (right side in FIG. 4) of the insertion portion 14 a, is covered with a resin cover 15. . Therefore, the rear end face of the resin cover 15 is open. Therefore, the protective cover 16 made of resin is joined to the opening, and the joint 17 is ultrasonically welded.

Thus, a space 18 is provided between the protective cover 16 and the shield case 14 facing the protective cover, and the shield case 14 is provided with dowels 19, 19 comprising circular bosses or the like. Are provided, and the dowels 19 are protruded into the space 18. Also, the dowels 19, 19 ...
May be formed so as to be in contact with the inner surface of the protective cover 16, but should not be limited to this.

In the drawings, reference numeral 20 denotes an engaging claw, which is formed so as to elastically engage with a notch hole provided in a mating opening of a mating connector. By pressing a pressing piece 21 provided on the surface of the connector 10, the engaging claw 20 is detached from the notch hole so that the connector 10 can be disengaged from the mating connector. I have.

Thus, the protective cover 16 is joined to the rear end face of the resin cover 15 and the joint 17 is ultrasonically welded. Conventionally, since the shield case 14 and the protective cover 16 are in close contact over almost the entire surface, the protective cover 1
6, the shield case 14 is pushed into the space 18 while the dowels 19, 19,... Bite into the inner surface of the protective cover 16 in the embodiment of the present invention. Therefore, the occurrence of the wrinkles is prevented.

The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified one.

[0013]

According to the present invention, as described in detail in the above-described embodiment, the joint between the resin cover for covering the connector and the protective cover to be joined to the opening at the rear end surface of the resin cover is made ultrasonic. At the time of welding, a predetermined space is provided between the shield case facing the protective cover and a dowel provided on the shield case is projected from the space, so that the outer surface of the protective cover is formed on the outer surface of the protective cover as in the related art. No wrinkles are produced, and thus the appearance is not hindered. Further, when the socket connector and the plug connector are inserted and removed, the movement of the shield case within the resin cover of the socket connector can be prevented, and the fitting operation between the connectors can be performed smoothly.
