Abstract
The utility model relates to an impedance tester, in particular to a static impedance tester for positive powder materials of cobalt-overlapped type spherical nickel hydroxide. The static impedance tester comprises a cylindrical insulation body made of poly ethylene (PE), wherein, round grooves with the same diameter are arranged at the upper portion and the lower portion of the insulation body, a through hole for being connected with the round grooves is arranged in the middle of the insulation body, and the diameter of the through hole is smaller than that of each round groove. A pure copper ring is installed in the upper groove, and a lower pure copper conductor is installed in the lower groove. The static impedance tester is further provided with an upper pure copper conductor in a screw shape, wherein, the lower end of the upper pure copper conductor penetrates through the pure copper ring and extends into the through hole in the middle of the insulation body, and the upper end of the upper pure copper conductor is adhered to the top plane of the pure copper ring. Compared with the prior art, the static impedance tester for the positive powder materials of the cobalt-overlapped type spherical nickel hydroxide has the advantages of being less in material consumption, high in impedance detection and the like. In addition, the materials are easy to manufacture.
