Moving contact and connecting assembly thereof

Abstract

The invention discloses a moving contact and a connecting assembly thereof in the field of power supply equipment. The hinge comprises a hinge rod and a plurality of convex blocks, the convex blocks penetrate through the hinge rod and are connected with the hinge rod through a reset spring. The hinge rod is rotatably connected with a plurality of moving contacts, each moving contact is provided with two clamping holes and a through hole for the hinge rods to penetrate through, a channel for the reset spring to enter and exit is formed in each clamping hole, a funnel is arranged at one end, faraway from the corresponding clamping hole, of each channel, and an electromagnet is arranged at the position, close to the corresponding clamping hole, of each moving contact. According to the devicein the scheme, the reset springs on a circuit breaker can be aligned to the clamping holes of the moving contacts, and the moving contacts are prevented from moving along the axial direction of the hinge rod when the moving contact rotates.

Description

technical field [0001] The invention relates to the field of power supply equipment, in particular to a moving contact and a connecting assembly thereof. Background technique [0002] The contact system of circuit breakers currently on the market is generally divided into two parts: the moving contact and the static contact, that is, the static contact is fixed on the base of the circuit breaker, the moving contact is fixed on the moving contact bracket, and the return spring It is fixed on the circuit breaker shell, and the return spring is clamped in the clamping hole of the moving contact, and the moving contact is driven to move within a certain range through the movement of the moving contact bracket, and the contact between the moving contact and the static contact or Separation achieves the purpose of connecting or disconnecting the circuit breaker. When the traditional circuit breaker clamps the return spring into the clamping hole of the moving contact, it is easy ...

AI Technical Summary

Problems solved by technology

When the traditional circuit breaker clamps the return spring into the clamping hole of the moving contact, it is easy to misalign the position, resulting in the return spring not being completely locked into the clamping hole of the moving contact, and manual correction is required. It is hinged on the moving contact bracket, but there is no axial limit between the moving contact and the moving contact bracket

Therefore, when the moving contact rotates, the moving contact will move axially, and there may be poor contact between the moving contact and the static contact, so that the circuit breaker cannot be broken normally.
