[0029] Furthermore, the busbar 4 is provided with a limiting hole 41 adapted to the first clamping portion 12. By providing the limiting hole 41, the first clamping portion 12 is limited. When the busbar 4 is clamped in the clamping groove 15, the first clamping portion 12 is clamped in the limiting hole 41, and the busbar 4 is not easy to fall off from the plastic bracket 1, thereby improving the stability of the installation of the CCS collection component.

[0030] Further, the lower end surface of the first clamping portion 12 is provided with a guiding inclined surface 16 facing the busbar 4, and the guiding inclined surface 16 is inclined upward along the direction of the limiting groove 17, and the guiding inclined surface 16 is used to guide the first clamping portion 12 to be clamped in the limiting hole 41. By providing the guiding inclined surface 16, during the installation of the busbar 4, the busbar 4 can follow the guiding inclined surface 16, so that the first clamping portion 12 can be clamped in the limiting hole 41.

[0032] Furthermore, a limiting groove 17 is provided on the side of the second clamping portion 13 facing away from the busbar 4, and the limiting groove 17 is used to limit the position of the second connector 6. By providing the limiting groove 17, during the installation process of the CCS collection component, a positioning function is played, and the second connector 6 can be inserted into the limiting groove 17 before assembly, which can avoid the second connector 6 from being pasted and skewed, thereby improving the reliability and assembly efficiency of the CCS collection component.

[0033] Furthermore, the number of the first clamping parts 12 is two, the number of the second clamping parts 13 is at least two, the two first clamping parts 12 are respectively arranged on the upper parts of the two opposite side walls of the bracket body 11, at least one second clamping part 13 is arranged on one side of the lower end surface of the bracket body 11, and at least one second clamping part 13 is arranged on the other side of the lower end surface of the bracket body 11, and a clamping groove 15 for clamping with the bus 4 is formed between the first clamping part 12 and the second clamping part 13 located on the same side of the first clamping part 12.
