Device for automatically detecting conduction resistance value of electric connector

The invention relates to an electric connector conduction resistance value automatic detection device, which comprises a test platform, a tester, a test cable, an elastic probe and a clamping mechanism, and is characterized in that one end of the test cable is provided with a tool plug, the tester is provided with a lead, one end of the test platform is provided with a triaxial test mechanism, and the triaxial test mechanism is provided with a CCD camera; the testing device has the advantages that a four-wire method testing loop is formed among the elastic probe, the testing cable, the tester, the lead and the to-be-tested sample, the lead comprises two wires, during testing, the two wires form a voltage loop and a current loop respectively, the resistance value on the voltage loop is extremely large, and the flowing current is extremely small and can be ignored, so that the testing accuracy is greatly improved. The test current on the current loop is the current of the to-be-tested sample, and the measured r
