一种改良结构的触头盒

Abstract

The utility model provides a contact box with an improved structure, which belongs to the technical field of electrical appliances. The contact box solves the technical problems of the conventional contact box that as heat inside the contact box cannot be continuously discharged, the service life of the contact box and the safe operation of a high voltage switch are influenced. The contact box comprises a box body with a wire inlet and a wire outlet, an insert for fixing a static contact and a mounting base, wherein the insert and the wire outlet are correspondingly arranged at the top of the box body, and a heat dissipation port communicating the interior and the exterior of the box body (1) is formed on the box body. The contact box with the improved structure can discharge the heat from the box body in time and can relieve pressure, so as to ensure the service life of the contact box and prevent the occurrence of creepage.
