Description

Technical Field

[0001] The utility model relates to the field of lithium battery assembly, in particular to a copper busbar insulating connector. Background Art

[0002] The battery pack is an important component of electric vehicles, used to store and output electrical energy. Its performance and safety have a significant impact on the performance and safety of the entire vehicle. With the diversification of battery pack solutions and the increasing demand for battery pack production capacity, the requirements for copper busbar protection are becoming more stringent.

[0003] Existing copper busbar insulation connectors are mostly adhesive-backed clips and round hole injection-molded clips. The round hole injection-molded clips are injection-molded, which has a complex process and cannot be applied to a variety of copper busbar solutions. The production cycle is slow and the production cost is high. In addition, the tongue is round, and the plastic ages and hardens in the later stage, causing the elastic function to gradually disappear. The tongue will rotate with the deformation of the copper busbar to cause a greater failure form in other parts of the copper busbar. Utility Model Content

[0010] Beneficial effect: Through the cooperation between the buckle, the first clamping plate and the second clamping plate, the buckle is clamped in the clamping slot for fixation, ensuring that the buckle firmly fixes the copper busbar.

[0011] Furthermore, a handle (13) is fixed to a side of the top of the second clamping plate (12) away from the first clamping plate (11).

[0015] Furthermore, the vertical cross-section of the extrusion component (4) is arranged in an inverted V shape.

[0016] Furthermore, a latch tongue (5) is fixed at the intersection of the extrusion components (4).

[0018] Furthermore, the vertical cross-section of the latch tongue (5) is V-shaped.
