Description

Technical Field

[0001] This invention relates to a power transmission device, including an electrical connection assembly of the power transmission device and an electrical connection product including the electrical connection assembly. Background Technology

[0002] In existing technologies, conventional wires with large cross-sections are typically used to transmit current between the battery pack and the power source in new energy electric vehicles. Since the charging current of the battery pack can reach as high as 1000A, this results in a high temperature rise in conventional wires, making it difficult to meet requirements and sometimes even causing fires. Furthermore, conventional wires use copper cores, and large-section copper cores are very expensive.

[0003] In existing technologies, aluminum busbar wires are typically used instead of traditional copper core wires to reduce wire temperature rise and cost. However, existing aluminum busbar wires consist of only a single aluminum busbar. When multiple different conductive components need to be electrically connected separately, multiple aluminum busbar wires are required, which makes electrical connections inconvenient and results in overly large and expensive electrical connection products.
