Conductive gasket shielding performance testing device

The utility model discloses a device for testing the shielding performance of a conductive gasket in the technical field of electromagnetic compatibility, and aims to solve the problems that the shielding characteristics of different conductive gaskets cannot be quickly and conveniently tested and the shielding characteristics of the conductive gaskets cannot be tested under different pretightening force conditions in the prior art. The device comprises a main body, an injection connector, a test connector, an insulator, a measurement conductor, a pressing assembly, an end cover and a matching resistor. The shielding performance testing device is suitable for testing the shielding performance of the conductive gasket, and the shielding performance of different conductive gaskets can be rapidly and conveniently tested only by replacing the tested conductive gasket; the shielding characteristic test of the conductive gasket under different pre-tightening force conditions can be realized only by adjusting the pr
