[0033] On the basis of the base and the capacitor voltage divider body, an upper wiring end, a conductive spring clip and a first pressing block are additionally provided, and the conductive spring clip is embedded and fixed in the upper wire cavity. When the wire is inserted into the upper wire cavity and embedded in the conductive spring clip, the other end of the first pressing block is inserted into the upper wire cavity by swinging, and the conductive spring clip is pressed against the conductive spring clip to clamp and lock the wire, so that the wire at the upper wiring end can be quickly installed and the wiring is convenient, thus solving the problem of inconvenient wiring on the capacitor voltage divider body at present, and facilitating the subsequent high-voltage AC withstand voltage test.

[0034] Similarly, the capacitor voltage divider with convenient wiring also includes a lower wiring end, a metal spring clip and a second pressing block; the lower wiring end is connected to the base and electrically connected to the capacitor voltage divider body; the lower wiring end has a lower wire cavity for inserting a wire; the metal spring clip is embedded and fixed in the lower wire cavity and electrically connected to the lower wiring end, and is used to clamp the wire inserted into the lower wire cavity; a second pressing slot corresponding to the position of the metal spring clip and communicating with the lower wire cavity is opened on the side wall of the lower wiring end; one end of the second pressing block is hinged in one end of the second pressing slot, and the other end can be swung relative to the side wall of the lower wiring end to be embedded in the other end of the second pressing slot and embedded in the lower wire cavity to press and contact the metal spring clip to clamp and lock the wire. In this way, the lower wiring end, the metal spring clip and the second pressing block are arranged, and the lower wiring end, the metal spring clip and the second pressing block are arranged on the lower wiring end. One end of the second pressing block is hinged to one end of the second pressing slot, and then the metal spring clip is embedded and fixed in the lower wire cavity. When the wire is inserted into the lower wire cavity and embedded in the metal spring clip, the other end of the second pressing block is swung and embedded in the lower wire cavity, and the metal spring clip is pressed to clamp and lock the wire, so that the wire at the lower wiring end can be quickly installed and the wiring is convenient, which solves the problem of inconvenient wiring on the capacitor voltage divider body at present, and is conducive to better completion of subsequent high-voltage AC withstand voltage tests.
