In electronic equipment and instruments, relays are used to control the switching and protection functions of the circuit. Using an injection molded relay base can ensure a reliable connection between the relay and the circuit board, and provide good electrical contact and thermal management

[0003] In some applications, the relay generates a certain amount of heat when it is working. The relay base can be used as a part of the heat dissipation, and the metal contact with a large contact area can help to dissipate the heat, so as to maintain the normal working temperature of the relay and the surrounding electronic components. However, in the prior art, when some relay bases are used, the relay bases are connected by bolts and nuts, which requires the use of special tools for disassembly, which makes it difficult to repair or replace the relay.
