Description

Technical Field

[0001] This utility model relates to the field of connector testing fixture technology, and in particular to a test fixture for replaceable core connectors used in photovoltaic modules. Background Technology

[0002] Connectors are required for power testing of photovoltaic modules. However, repeated insertion and removal of the connectors increases contact resistance, affecting the accuracy of power test results. Therefore, connectors need to be replaced periodically, leading to high operating costs. The challenge lies in how to quickly replace them while ensuring good conductivity at the connection points. Currently, methods typically involve directly twisting the metal wires together and soldering them, or using alligator pliers to clamp the new connector wires. However, these methods struggle to control contact resistance at the connection points, easily resulting in inaccurate power test results. Utility Model Content
