Abstract
The utility model provides a connector for testing the wet leakage current of a photovoltaic cell assembly and belongs to the field of testing components. The connector comprises an external electrode connected with an insulation and voltage-resistance tester, and an insulation sucker, and the center of the back surface of the absorption surface of the insulation sucker is provided with a cylindrical bulge. The external electrode hermetically passes through the cylindrical bulge to extend into the absorption surface of the insulation sucker and then is connected with the upper end of a metal spring electrode. The lower end of the metal spring electrode is connected with a metal contact piece. During testing, no extra junction box is needed, so that the waiting time is shortened. When the testing is completed, the assembly can be transmitted to the operation procedure normally. Since neither adhesives nor junction boxes are adopted during the testing process, the testing cost is reduced. Due to the adoption of the connector, photovoltaic cell assemblies can be tested timely during the operation procedure, so that the purposes of timely detecting problems and shortening reaction time are realized. Therefore, the good control over the product quality is realized.
