Problems solved by technology

[0003] However, the existing static contact mounting inserts on the contact box need to determine the threaded holes used with the static contacts during production, and the threaded holes are reserved to fix the static contacts with the contacts and the bolts. Inside, but when installing the bolts, you need to turn your hand in and out through the other end to twist the bolts. Due to the small space of the contact box, the installation is more troublesome, and the reserved threaded holes cannot be adapted to all contacts. Inside the box, during the installation process, it is easy to cause the static contact to shake inside the contact box, and there is a gap. When the voltage is higher, discharge in the gap is more likely to occur, which makes the switchgear a potential safety hazard.

Abstract

The improved contact box comprises a contact box body, an insulating partition plate is fixedly arranged in the contact box body, the insulating partition plate is a circular partition plate, the outer side wall of the insulating partition plate is fixedly connected with the inner side wall of the contact box body, and a static contact is inserted into one end of the contact box body. According to the invention, the push-out assembly is additionally arranged, and the push assembly and the limiting assembly are cooperatively used, so that the placement box can be taken out, the horizontal extrusion plate extends out of the interior of the placement box, and the horizontal extrusion plate can be pushed out of the interior of the placement box; according to the invention, movement of the placing box in the vertical direction and movement of the horizontal extrusion plate in the horizontal direction can be realized, extrusion and limiting effects can be achieved between the static contact and the insulating partition plate after the horizontal extrusion plate extends out, the placing stability of the static contact is improved, and positioning of the horizontal extrusion plate after the horizontal extrusion plate extends out can be realized through cooperation with the anti-reverse-pushing assembly. Therefore, the danger in the use process of the switch cabinet caused by the shaking of the static contact is avoided, and the use safety is effectively improved.

Description

technical field [0001] The invention relates to the technical field of contact boxes, in particular to an improved contact box. Background technique [0002] The main function of the contact box is to insulate and connect the connection part of the incoming and outgoing lines. At present, the general contact box structure includes an epoxy body formed by epoxy material gel, one end is open and the other end is closed. The side wall and bottom of the upper part of the cylinder are respectively provided with outlets and inlets. There is a static contact installation insert on the top of the cavity, and the busbar extends into the insulating cylindrical body through the outlet, and is electrically connected with the static contact installation insert. The outer and inner sides of the cylindrical shape are provided with umbrella skirts, and the bottom of the product is Features four mounting flanges. [0003] However, the existing static contact mounting inserts on the contact...
