Embodiment 1

[0069] see figure 1 , which is a plug-in PCBA connection terminal provided by the present invention. The connection terminal includes a first metal terminal 10 and a second metal terminal 20 connected to each other, the first metal terminal is an integral piece made of copper for electrical connection with the PCBA board; the second metal terminal is made of aluminum One-piece piece for electrical connection to a mating connector made of aluminum.

[0070] Please also refer to figure 2 , the first metal terminal has a first connection body 11 . One end of the connecting body is the elastic portion 12 , and the other end is the first connecting portion 13 . The first connecting part is a plate structure, which is formed by extending forward from the connecting body, and a riveting hole 14 is arranged in the first connecting part. The elastic portion protrudes from the surface of the first connection body and forms an L shape with the connection body.

[0071] The elastic ...

Embodiment 2

[0083] See Figure 7 , as a modification of the first embodiment, the present invention also provides another connection terminal. Different from the first embodiment, the connection terminal includes a second metal terminal different from the second metal terminal described in the first embodiment.

[0084] The second metal terminal includes a second connection body 21 . One end of the second connection body is an electrical connection portion 22 , and the other end is a second connection portion 23 . The electrical connection part is a flat plate structure, which is welded by laser after it is pasted on the mating connector.

[0085] The second connecting portion is a plate structure, which is attached to the first connecting portion 13 of the first metal terminal 10 . There are three connection modes between the first connection part and the second connection part, as follows:

[0086] The first, see Figure 8 The first connecting portion of the first metal terminal an...

Embodiment 3

[0093] see Figure 12 , The invention provides an electrical connection assembly. The electrical connection assembly includes plastic parts 30 , bus bars 40 , PCBA board 50 and the connection terminals described in the first embodiment. The plastic part has a sealing holding part 31 that wraps and seals the riveting part. The electrical connection portion of the second metal terminal protrudes outside the seal holding portion. The bus bar has several outwardly extending lugs 41 (see Figure 13 ). The lug corresponding to the connection terminal has a connection hole 42 set on the electrical connection part, and then laser is used to weld the lug and the electrical connection part into one. The PCBA is provided with a socket 51; the wall surrounding the socket is coated with a conductive copper foil layer; the elastic part 12 of the first metal terminal is inserted into the socket, and the shrapnel elastically presses against the wall of the hole.

[0094] The seal holder ...

Abstract

The invention solves the technical problem that the PCBA board of the automobile battery module is soldered and fixedly connected with the connection terminal in the prior art, and the PCBA board cannot be replaced separately. The invention provides a plug-in type PCBA connection terminal. The connecting terminal comprises a first metal terminal and a second metal terminal, wherein one end of thefirst metal terminal is an elastic part and the other end is a first connecting part; The elastic portion has a plurality of elastic pieces arranged in a front-rear arrangement, the elastic pieces areinserted into a PCBA board jack hole, and the elastic pieces are elastic pressed on an inner wall of the jack hole. In addition, the invention also provides an electrical connection assembly, which comprises a plastic member, a bus bar, a PCBA board and the connection terminal. The elastic part of the first metal terminal is inserted into the nickel-plated jack hole of the PCBA board, and the elastic piece is elastically pressed on the inner wall of the jack hole of the PCBA board and electrically connected with the PCBA board. The connecting terminal and the PCBA board are plugged and pulledout by the elastic piece for many times, and the PCBA board is provided with maintainability and convenient replacement by the bolt fixation. The elastic part of the first metal terminal is insertedinto the nickel plated jack hole of the PCBA board.

Description

technical field [0001] The invention relates to a connection terminal, and mainly relates to a terminal connected with a PCBA and an electrical connection assembly. Background technique [0002] The connection between the PCBA and other electronic components in the car battery module generally uses connection terminals. In the prior art, in order to obtain stable connection performance, the connection between the connection terminal and the PCBA needs to be welded and reinforced. If the PCBA board is damaged during use, the entire electrical connection assembly of the battery module needs to be replaced, resulting in high repair costs for the car battery. [0003] The Chinese patent with the application number: CN201520531057.4 discloses "a crimping terminal for connecting PCB boards". It can increase the lateral extrusion between the crimp terminal and the PCBA board, and realize the tight connection between the connector and the PCB board without soldering process, and ...
