The conductive fabric can be used for manufacturing shielding work clothes of professionals engaged in high-radiation work such as electronic and electromagnetic, shielding cloth special for shielding rooms, shielding covers of precise instruments, radiation-proof curtains and the like.

To know whether the conductivity of the conductive fabric meets the design requirements, the resistance of the conductive fabric needs to be tested. At present, a common conductive fabric detection instrument connects a conductive fabric between two electrodes spaced apart from each other in a clamping or pressing manner, and calculates a corresponding resistance according to a voltage and a current measured between the two electrodes. However, the connection between the conductive fabric and the electrode is always one of the important sources of detection errors. In recent years, with the rapid development of the conductive fabric industry and the continuous improvement of the requirement on the detection precision, the detection error is increasingly non-negligible.

When the measuring device is used, the conductive fabric to be measured is flattened and clamped between the pair of electrode assemblies, and the pair of electrode assemblies are electrically connected in the measuring circuit for measurement. Specifically, the lower electrode plate and the upper electrode plate of one set of electrode assembly jointly form a connecting end to be connected into the measuring circuit, and the lower electrode plate and the upper electrode plate of the other set of electrode assembly jointly form a connecting end to be connected into the measuring circuit. Because the briquetting pushes down the pivot with elasticity, can make both ends pressure tend to equal spontaneously when going up the electrode piece and pushing down, on this basis, go up the elastic action of cushion and lower cushion and further make and go up the electrode piece and all equal with lower electrode piece everywhere pressure, make the electrically conductive surface fabric that awaits measuring of centre gripping between last electrode piece and lower electrode piece and go up the electrode piece and form reliable electricity with lower electrode piece and be connected to reduce measuring error.
