AI Technical Summary

Technical Problem

Existing electromagnetic relays struggle to balance improving the structural strength of the drive card with increasing the space for coil winding, thus limiting performance improvements.

Method used

An electromagnetic relay was designed, which adopts a push card connection structure that is recessed in the direction away from the coil frame, and sets an arched cavity wall in the receiving cavity of the base to increase the winding space of the coil. At the same time, the structural strength and motion stability of the push card are improved by the limiting structure.

Benefits of technology

This improved the structural strength of the drive card and expanded the coil winding space, enhanced the power consumption performance of the electromagnetic relay, simplified the production process, and reduced costs.

Abstract

This application relates to an electromagnetic relay, including a coil frame and a pusher. A coil is wound on the coil frame. The pusher is correspondingly disposed with respect to the coil frame, and includes a first pusher arm, a second pusher arm, and a connecting structure. The first and second pusher arms are spaced apart, and the connecting structure is disposed between and connected to both the first and second pusher arms. The connecting structure is recessed in the direction away from the coil frame to increase the winding space of the coil. Thus, the first pusher arm is connected to the second pusher arm through the connecting structure, thereby improving the structural strength of the pusher. Because the connecting structure is recessed in the direction away from the coil frame, the winding space of the coil is increased, which is beneficial to improving the power consumption and other performance characteristics of the electromagnetic relay.
