[0039] The conductive contact assembly is mounted on the top surface of the tool body 1 , and is electrically connected to the conductive contact tube 3 .

[0040] In the utility model, the tooling body 1 is fixedly installed above the production line. When in use, the conductive contact tube 3 is connected to the conductive joint of the photovoltaic module, and is connected to the IV testing mechanism through the conductive contact component to start the IV test. Among them, the stabilizing component is sleeved on the outer wall of the conductive contact tube 3 and is located between the conductive contact tube 3 and the conductive joint of the photovoltaic module, which can effectively prevent the conductive contact tube 3 from loosening or falling off from the conductive joint of the photovoltaic module, resulting in power abnormality or black screen during the test. At the same time, the protective component can prevent the conductive joint of the photovoltaic module from being greatly deflected during the test, resulting in damage to the conductive contact tube.
