Description

Technical Field

[0001] The utility model relates to the technical field of connecting devices, in particular to a connecting device for battery aluminum bar connectors. Background Art

[0002] Battery connectors are conductor connectors that connect the terminals of several independent battery modules, batteries, or battery packs and carry current. They can connect multiple low-voltage batteries to form a high-voltage battery pack to meet the needs of actual applications. Therefore, battery connectors should have good conductivity and compatibility to ensure normal power supply or communication of the system.

[0003] However, in the process of implementing the relevant technical solutions, it was found that there are at least the following technical problems: currently, copper materials are mostly used as connectors, but in order to reduce prices, aluminum materials are used as connectors in some cases. The thermal expansion coefficient of aluminum in the aluminum busbar connection is high and the hardness of aluminum is lower than that of copper busbar. When the aluminum busbar is connected with bolts at the connection, due to the low hardness of aluminum and the vibration of the battery or changes in hot and cold environments, the locking torque of the screw at the connection will be weakened, which will cause the torsional loosening problem at the battery electrical connection. Therefore, a connection device for the battery aluminum busbar connector is needed. Utility Model Content
