AI Technical Summary

Technical Problem

The existing electromagnetic relay coils will generate a large amount of heat when they are powered on for a long time, affecting the stability of use and service life.

Method used

An electromagnetic relay is designed, which includes a shell, a static contact piece, a moving contact piece, a coil bracket and a coil. By arranging a self-locking plate and a vertical guide groove on the inner wall of the casing, and arranging guide bumps and springs on the edge of the movable contact piece, the coil does not need to conduct electricity for a long time, thereby avoiding the generation of heat.

Benefits of technology

By not requiring the coil to conduct electricity for a long time, heat generation is avoided, the service life and smooth use of the relay are improved, and the effectiveness of conduction and disconnection is ensured.

Abstract

The invention discloses an electromagnetic relay which comprises a shell, a static contact piece fixed in the shell and a movable contact piece arranged in the shell, a coil support and a coil arranged on the coil support are fixed in the shell, and the coil support is matched with the movable contact piece in position. A self-locking plate is arranged on the inner wall of the shell, a vertical guide groove is formed in the side face of the self-locking plate, and an arc-shaped clamping protrusion is arranged in the middle of the side wall of the vertical guide groove. The edge of the movable contact piece is provided with a guide bump, a first spring is fixed between the guide bump and the top wall of the vertical guide groove, and a second spring is fixed on the bottom wall of the vertical guide groove. According to the invention, the structure arrangement is reasonable, the coil does not need to be conducted for a long time, so that the coil can be prevented from generating a large amount of heat, the energy-saving effect can be improved, the service life of the whole structure is prolonged, the effectiveness of conduction and disconnection can be ensured, and the use stability and reliability of the whole structure are improved.
