AI Technical Summary

Technical Problem

Existing electromagnetic relays are difficult to install stably in a limited space while also effectively increasing heat dissipation space, which affects their service life.

Method used

The width of the support mounting part of the normally open stationary spring terminal is smaller than that of the contact mounting part. Combined with the multi-point positioning mounting structure on the base, including the cooperation of the side positioning block and the groove, and the upper limit block and the stepped surface, a three-dimensional positioning is formed, which enhances the installation stability and releases heat dissipation space.

Benefits of technology

While ensuring stable installation, it significantly reduces the space occupied by the support installation part, increases the heat dissipation channel, improves heat dissipation performance and extends the life of the relay, and the multi-point positioning enhances the resistance to vibration and impact.
