Abstract

The invention discloses a relay device which comprises a casing, a normally-closed terminal, a normally-open terminal, a coil terminal, a solenoid, an electromagnet and a first armature. The lower ofthe first armature makes contact with the electromagnet selectively, the upper of the first armature is vertically connected with a second support, the outer side of the second support is connected with a moving contact, the moving contact is positioned between the normally-closed terminal and the normally-open terminal, a first insertion rod is inserted movably into the outer side of the casing,and connected with a limiting ring, a second spring is connected between the limiting ring and the inner wall of the casing, a blind hole is formed in the lower portion of the inner side of the firstinsertion rod, a second insertion rod is movably inserted into the internal of the blind hole via a third spring, the lower of the second insertion rod is connected with the a first wedge plate, the inner bottom side of the casing is connected with a second wedge plate and a third support, the upper of the third support is movably hinged to a second armature via a hinging wheel, and the internal side of the second armature is vertically connected with a dial rod. The relay device can overcome disadvantages in the prior art, and has functions of power-on reset protection.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a relay device. Background technique [0002] The relay is an electronic control device, which has a control system and a controlled system. It is usually used in automatic control circuits. It is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic adjustment, safety protection, conversion circuit, etc. in the circuit. It is a power switch that cuts off or connects the electrical circuit by responding to electrical signals. It is widely used in vehicles, various mechanical equipment and electronic products. , is an essential and important component in the power system. Chinese utility model patent CN 206564226 U discloses a relay with a manual switch. The relay with this structure adds a manual button, which enables the staff to temporarily control the electrical on-off, but in actual use, staff often ...
