Elastic electrode for precision resistance measurement

The utility model relates to the technical field of diamond and superhard composite materials, in particular to an elastic electrode for precision resistance measurement, which comprises a fixture and is characterized in that the fixture is provided with a conical lantern ring, mounting holes are arranged on the periphery of the conical lantern ring, a metal net is mounted on the conical inner wall of the middle of the conical lantern ring, and the metal net is provided with a metal wire. The lower part of the metal net is filled with an elastic medium, the upper part of the elastic medium is provided with a conical pressing plate, and the conical pressing plate and the conical lantern ring are matched to fix the metal net, so that the elastic electrode for precision resistance measurement has the advantages that the electrode is simple in structure and convenient to use, the contact area between the carbon tube and the electrode can be increased, and the measurement precision is improved. The interface resis
