technical field

The utility model relates to the technical field of electrical accessories, in particular to a novel combined relay.

Background technique

A relay is an electrical control device, which is an electrical appliance that makes a predetermined step change of the controlled quantity in the electrical output circuit when the change of the input quantity meets the specified requirements. It has a connection between the control system and the controlled system. The interactive relationship is usually used in automated control circuits. It is actually an automatic switch that uses a small current to control the operation of a large current.

Patent No. CN 106486324 A discloses a relay, which can save power and energy during use, and the relay has strong magnetic retention capability and little malfunction.

The above relays have the following disadvantages during use: 1. The relays are usually independent and separate fixed structures. Before use, it is generally necessary to drill holes to install the relays on the surface of the mounting body. When multiple sets of relays need to be installed at the same time, more installation holes must be drilled. It is cumbersome, laborious, and not convenient enough; 2. The relay is generally installed directly on the surface of the installation body and is in direct contact with the external environment. The dust and impurities in the external environment are easy to fall into the interior of the relay, which affects the service life and stability of the relay. Therefore, we propose a new type of combined relay.
