Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to a composite relay conductive device and a composite relay socket. Background Technology

[0002] A relay is an "automatic switch" that uses a small current to control a large current. It plays a role in circuits such as automatic adjustment, safety protection, and circuit switching.

[0003] In electrical control cabinets, relays are usually used in conjunction with relay sockets. Several relay sockets are fixed on the guide rail with their long sides touching, and the short sides of the relay sockets face the upper and lower wire bars respectively, so that the wiring positions on the short sides can be connected to the upper and lower wire bars.

[0004] In addition to the two leads of the coil, a relay typically has two common leads, two normally open leads, and two normally closed leads. The relay socket usually has eight spring clips to connect to the relay's leads. Whether the connection between the spring clips and the relay socket terminals is achieved using traditional metal sheets or through printed circuit boards, the spring clips and relay socket terminals always correspond one-to-one.

[0005] However, in actual use, existing relays, because the clamping springs correspond one-to-one with the wiring positions, inevitably result in the wiring between the upper wire bar and the lower short side of the relay socket being connected, and the lower wire bar and the upper short side of the relay socket being connected. This leads to a situation where the wiring detours and crosses, resulting in wasted wires, complicated wiring processes, and increased maintenance difficulty. Utility Model Content

[0006] The purpose of this utility model is to provide a composite relay conductive device and a composite relay socket, which can realize the connection of multiple external terminals by one clamping spring.
