Conductive gasket shielding performance testing device

The invention 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 in the prior art, shielding characteristic testing cannot be quickly and conveniently carried out on different conductive gaskets, and the shielding characteristic testing of the conductive gasket under different pretightening force conditions cannot be realized. 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 device is suitable for testing the shielding performance of the conductive gasket, and shielding characteristic testing can be rapidly and conveniently carried out on different conductive gaskets 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 pre-ti
