[0002] A high-current connector assembly is a connector designed specifically for transmitting high currents and is widely used in industrial environments and electronic equipment that require high-power transmission. Existing high-current connector assemblies are often board-end connectors with a narrow range of applicability. They often cannot meet the needs of servers, power motherboards and other fields. Therefore, a combined high-current connector assembly is needed to meet usage requirements.

However, the assembly process of the board-end connector and the wire-end connector is relatively complicated. The board-end connector cannot be adapted to install wire-end connectors of various specifications. In addition, the terminals in the board-end connector and the wire-end connector have insufficient retention force, which will affect the use of high-current connector components.
