The end of the bracket 31 is inserted into the through slot of the first card slot 332, and the clamping block 331 and the first card slot 332 are clamped together by the cooperation of the limiting boss and the through slot; the second card slot 334 is arranged on the bottom surface of the connecting end of the bracket 31, and a clamping plate is arranged at the bottom, and the second card slot 333 is provided with a groove that cooperates with the clamping plate, and the second card slot 333 is inserted into the second card slot and the clamping block 333 and the second card slot 334 are clamped together by the cooperation of the clamping plate and the groove; the clamping direction of the first card slot 331 and the first card slot 332 is vertically arranged, and the clamping direction of the second card slot 334 and the second card slot 333 is horizontally arranged, and the clamping direction of the first card slot 331 and the second card slot 333 is not in the same direction, and the cooperation of the two buckles can ensure that the voltage collection module 3 is firmly connected. Each voltage collection module 3 is connected by a buckle connection, which has a simple structure, a firm connection, and is easy to disassemble and assemble.

[0033] Among them, Figure 1-2 As shown, the temperature acquisition module 1 includes a bracket 2 11, and the bracket 2 11 is plugged into the bracket 1 31. The bracket 2 11 is provided with connecting grooves 111 on both sides adjacent to the voltage acquisition module 3. The outer side of the bracket 1 31 is provided with a T-block 34 corresponding to the connecting groove 111, and the T-block 34 is plugged into the connecting groove 111. The temperature acquisition component 100 and the voltage acquisition component 200 are assembled by plugging the T-block 34 into the connecting groove 111, which has a simple structure and is easy to disassemble and assemble.

[0034] Example 2

[0035] Based on the structure of Example 1, Figure 1-4As shown, the voltage collection module 3 includes an integrally formed bracket 1 31, and the bracket 1 31 includes at least one connection unit 310 for assembling the output pole module 4 and the voltage collection module 5. The connection unit 310 is arranged in a one-to-one correspondence with the output pole module 4 and the voltage collection module 5, that is, two types of connection units 310 are arranged on the bracket 1 31, namely, the connection unit 1 310A according to the output pole module and the connection unit 2 310B for installing the voltage collection module 5, and the adjacent connection units 310 on the bracket 1 31 are connected by a telescopic structure.

The busbar will be connected to the voltage collection module 3 and the battery cell group through laser welding and welding with the positive and negative poles.

The traditional telescopic method is to set a telescopic convex groove on the busbar. This telescopic convex groove is a rigid telescopic structure set on the busbar. The expansion or contraction still has an impact on the weld between the busbar and the pole, and the effect is not good. The tensile strength of the busbar must be greater than the tensile strength of the bracket 1 (made of insulating plastic). When the battery cell group expands or contracts, the U-shaped telescopic groove 32 will firstly expand the convex groove to adapt to this expansion or contraction, minimizing the impact on the weld. The present invention adopts a method of combining the U-shaped telescopic groove 32 with the telescopic convex groove on the busbar, which can minimize the impact of the expansion or contraction of the battery cell group on the weld, extend the maintenance cycle, and greatly improve the service life of the integrated busbar.
