AI Technical Summary

Technical Problem

In traditional relays, the insufficient material deformation and mechanical stability of the plastic hook structure lead to inconsistent spacing between the moving and fixed contacts, affecting contact reliability and electrical life.

Method used

The armature is used to form a mechanical stop structure with the vertical part of the armature and the upright plate. The armature is reset to abut against the upright plate to maintain a constant distance between the moving contact and the fixed contact. Combined with the guide structure of the mounting groove and the limiting protrusion, the stable movement of the armature is ensured.

Benefits of technology

It achieves constant contact spacing, improves contact reliability and electrical life, enhances action stability and response speed, and is suitable for high-frequency operation scenarios.

Abstract

This utility model discloses a relay with constant contact spacing, belonging to the field of relay technology. It includes: an L-shaped mounting bracket, a coil assembly mounted on its horizontal plate, an armature with a moving contact, and a spring providing reset force. The armature consists of a horizontal part and a vertical part. The horizontal part is rotatably connected to the vertical plate, the moving contact is located on the horizontal part, and a fixed contact is located on the top of the coil assembly. In the de-energized state, the armature resets to its vertical position, abutting against the vertical plate to form a mechanical stop structure, thereby maintaining a constant distance between the moving and fixed contacts. By setting the vertical part of the armature to form a mechanical stop structure with the vertical plate, precise limiting is achieved in the de-energized state, fundamentally replacing the traditional plastic hook structure. This avoids changes in the position of the fixed contact due to material deformation or fatigue fracture, ensuring that the distance between the moving and fixed contacts remains constant after each armature reset, significantly improving the stability and lifespan of the electrical connection.
