标题(英语)

Precision measurement device for film resistor or chip resistor


摘要(英语)

The utility model relates to a measurement device for a resistor, in particular to a precision measurement device for a film resistor or a chip resistor. The measurement device comprises a frame, resistor measurement electrodes, a pressure adjusting mechanism, a spring pressure exerting mechanism and a pulling force mechanism. An upper measuring electrode and a lower measuring electrode are respectively and fixedly connected with the lower surface of the upper pressure head of pressure adjusting mechanism and the upper surface of the lower pressure head of the pressure adjusting mechanism through an insulation material layer, and the lower surface of the lower pressure head of the pressure adjusting mechanism is matched and connected with the upper surface of the pressing block of the spring pressure exerting mechanism through a ball and a concave spherical surface matched with the ball. The measurement device of the utility model can automatically adjust the contact area between an upper plane electrode, a lower plane electrode and a measured resistor, the positioning is flexible, and the maximum contact area between the resistor and the electrodes can be ensured. The spring pressure exerting mechanism can adjust pressure value according to different materials of the measured resistor, the deformation of a chip resistor or a film resistor is reduced, and the precision of the measurement is raised. The precision measurement device for a film resistor or a chip resistor is helpful to realize reliable, accurate and precise measurement for the chip resistor or the film resistor.
