Description

Technical Field

[0001] The utility model relates to an electric power transmission component, including an electric connection component of the electric power transmission component and an electric connection product including the electric connection component. Background Art

[0002] In the prior art, conventional wires with large cross-sections are usually used to transmit current between the battery pack and the power source of new energy electric vehicles. Since the current when the battery pack is charged is as high as 1000A, the temperature rise of conventional wires is high, which is difficult to meet the requirements and sometimes even causes fires. In addition, conventional wires use copper cores, and the cost of large-section copper cores is very high.

[0003] In the prior art, in order to reduce the temperature rise and cost of wires, aluminum bar wires are usually used to replace traditional copper core wires. However, the aluminum bar wires in the prior art only include a single aluminum bar. When multiple different conductive parts need to be electrically connected separately, multiple aluminum bar wires need to be provided, which makes the electrical connection inconvenient and causes the electrical connection product to be too large and the cost too high.
