Abstract

The utility model discloses a power connector, which comprises a binding post, an insulator, a transparent cover, an unloosening screw, a screw assembly, a square nut and a mounting plate. The binding post is fixed onto the insulator through the screw assembly and the square nut. The transparent cover is buckled on the insulator through the unloosening screw. The mounting plate is connected with the insulator. One positioning surface of the binding post is smaller than the accommodating cavity of the binding post on the insulator in size, so that the product assembly is facilitated. Another positioning surface of the binding post is larger than the accommodating cavity of the binding post on the insulator in size, wherein the positioning surface and the accommodating cavity are in reasonable interference fit with each other. Therefore, the holding force of the binding post on the insulator is ensured. The power connector has the advantages of simple structure, low cost, smaller package dimension, fast installation, multipurpose and the like.
