[0002] Since the copper busbar and the plastic-coated component are not integrated, their positions can be flexibly adjusted to facilitate adaptive changes in the holes at both ends, thereby reducing the risk of hole misalignment. At the same time, in order to further enhance the stability of the design, a heat conductive sheet is added between the copper busbar and the aluminum alloy shell. This heat conductive sheet not only has excellent thermal conductivity, but also has the characteristics of insulation and voltage resistance. It can efficiently conduct heat from the copper busbar, thereby ensuring the stable operation of the system. The setting of the three-phase plastic-coated copper busbar assembly is convenient for the purpose of line connection and current guidance and transmission.

At this time, the second combination ring 41 in the movable module 38 is subjected to pressure, which can drive the first combination ring 39 to rotate. At the same time, the second combination ring 41 cooperates with the telescopic adjustment to prevent the problem of jamming, thereby facilitating the regulation work.
