Description

battery connector

technical field

The utility model relates to a connector, in particular to a battery connector.

Background technique

Please refer to FIG. 4 , a battery connector 200 includes an insulating shell 5 , a metal shell (not shown in the figure) and a plurality of connecting terminals 7 . The insulating case 5 has a main body 51 and an embedded part 52 protruding from the main body 51 . The metal shell is fixed and covered on the embedded part 52 . The insulating shell 5 is provided with a number of terminal grooves 521 extending to the front face, the rear end face and the lower surface. In order to prevent the connection terminal 7 from conducting with the metal shell, the upper front ends of the adjacent two groove walls of the terminal groove 521 are respectively connected with a The supporting beam 522 is enclosed with the groove wall of the terminal groove 521 to form a front opening. The connection terminal 7 has a V-shaped contact portion 71, and a contact point 711 is formed at the bend of the contact portion 71 to movably protrude out of the insulating shell 5. One end of the contact portion 71 is connected to a repeatedly bending elastic Section 72.

However, when the above-mentioned known battery connector 200 is assembled, due to the design of the supporting beam 522, when the connecting terminal 7 is set in the terminal groove 521, it is necessary to use a jig to compress the elastic portion 72 of the connecting terminal 7 to make the connection. The contact portion 71 of the terminal 7 protrudes from the opening of the front end, which is not only complicated and difficult to assemble, but also the elastic portion 72 of the connecting terminal 7 tends to warp and contacts the metal shell to generate electrical conduction.

Utility model content

The purpose of this utility model is to provide a battery connector that is easy to assemble and can prevent the connection terminal from being connected to the metal shell to solve the above-mentioned shortcomings of the prior art.

To achieve the above purpose, the battery connector provided by the utility model includes an insulating shell, an insulating cover, a metal shell and a plurality of connecting terminals. The insulating case has a main body and an embedded part. The insulating case is provided with a number of terminal grooves extending to the lower surface; the connecting terminals are accommodated in the terminal grooves, and the connecting terminals have an elastic part formed by repeated bending and extending. The front end of the elastic part A contact portion is bent and extended, and the rear end of the elastic portion is protruded and bent to form a holding portion; the insulating cover is fastened to the lower surface of the insulating case; the metal shell is held and covered by the insulating case and the insulating cover.

As mentioned above, since the battery connector of the present invention replaces the support beam with the insulating cover, the connecting terminal can be directly placed in the terminal groove and then covered with the insulating cover when assembling without using jigs, so it is easy to complete the assembly action, and Since the insulating cover isolates the connecting terminal and the metal casing, it is possible to avoid conduction between the connecting terminal and the metal casing.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 and FIG. 2 , a battery connector 100 includes an insulating shell 1 , an insulating cover 2 , a metal shell 3 and a plurality of connecting terminals 4 .

Please refer to Fig. 2 and Fig. 3, the insulating case 1 is roughly rectangular, the insulating case 1 has a main body 11, the front end of the main body 11 protrudes to form an embedded part 12, and the front end of the embedded part 12 is flat Aligned, the two outer walls of the embedded part 12 each protrude to form a buckle 121 . The embedded part 12 is provided with several terminal grooves 122 extending to the front end surface, the rear end surface and the lower surface, and a partition wall 123 is formed between two adjacent terminal grooves 122, and the front part of the lower end surface of the partition wall 123 is A cylindrical positioning hole 124 is recessed at the same position. An engaging groove 125 is defined in the middle of the groove wall of the terminal groove 122 and the middle of the partition wall 123 . A retaining portion 126 protrudes from the rear portion of one side of the groove wall of the terminal groove 122, and an L-shaped holding portion 127 protrudes from the rear portion of the terminal groove 122, and the holding portion 127 and the holding portion A holding groove 128 is formed between 126 , and an insertion hole 1281 extending to the upper surface is defined on the bottom wall of the holding groove 128 .
