DETAILED DESCRIPTION

[0028] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0029] As Figures 1-10 Commonly shown, the embodiment about the integrated busbar novel structure assembly applied to the battery side installation, including the PACK box body 1 that is internally provided with the battery 2, the PACK box body 1 and the battery 2 are both prior art, the application does not limit the type of both, hereby explained.

[0030] ​​In the embodiment, the battery 2 is connected with the integrated busbar assembly 3, which is the same as the existing one, and the battery 2 and the integrated busbar assembly 3 are in a three-way connection relationship of electrical connection, mechanical connection and signal connection. Compared with the traditional integrated busbar, the integrated busbar assembly 3 of the embodiment includes a first mounting bracket 4 and a second mounting bracket 5 which are detachable and rotationally connected under external force. The first mounting bracket 4 and the second mounting bracket 5 are commonly connected with an FPC 6 which is bent by multiple bending plates. This facilitates the manufacturing and installation of the integrated busbar assembly 3, avoids the situation that the traditional battery box is difficult to install power / energy storage batteries and the integrated busbar thereon due to structural limitations, and then the free end of the first mounting bracket 4 is connected with an electrical insulation piece 7, and the aluminum bar 8 is connected to the electrical insulation piece 7.

The FPC 6, the electrical insulation piece 7 and the aluminum bar 8 are all prior art.

[0031] As shown in Figure 9 the end face of the end of the first mounting bracket 4 connected with the second mounting bracket 5 forms an inwardly recessed rotation fitting groove 16. Figure 8 As shown in

The first limiting grooves 12 and the second limiting grooves 13 are matched with the limiting protrusions 17, that is, the limiting protrusions 17 can be matched in the first limiting grooves 12 or the second limiting grooves 13 under the action of external force to form a limiting state. It can be understood that the matching of the limiting protrusions 17 with the first limiting grooves 12 or the second limiting grooves 13 changes the angle at which the first mounting bracket 4 and the second mounting bracket 5 are connected. It should be noted that the limiting grooves shown in the embodiment are two, but in actual processing and application, different numbers of limiting grooves can be opened according to needs, so as to realize more limiting angles at which the first mounting bracket 4 and the second mounting bracket 5 are connected.
