[0002] During battery testing, it is often necessary to use large currents to perform charge and discharge tests on the battery. As the capacity of the battery itself becomes larger and larger, the current used to charge and discharge the battery is also increasing. Larger currents place higher and higher requirements on the overcurrent capability of the connector, and large currents will cause a higher temperature rise on the overcurrent circuit. The larger the current, the higher the temperature rise, especially at the connection point on the circuit, which is also the point with the highest temperature rise due to the large contact resistance at the connection point. At present, during battery testing, it is usually necessary to directly lock the two sections of the wiring harness or lock the connection through a copper adapter, and dissipate heat through natural heat dissipation or air cooling. However, the copper adapter used in the prior art is only suitable for connectors with a smaller temperature rise, and there are technical problems such as inconvenience in disassembly and assembly, and difficulty in collecting battery test voltage.
