Description

Movable contact plate structure and pulse relay

Technical Field

The utility model belongs to the technical field of relays, and particularly relates to a movable contact plate structure and a pulse relay.

Background

The relay is an electric control device, and when a change in an input amount (excitation amount) reaches a predetermined requirement, a controlled amount is changed in a predetermined step in an electric output circuit. It has an interactive relationship between the control system (also called input loop) and the controlled system (also called output loop). It is commonly used in automated control circuits and is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, the circuit plays roles of automatic regulation, safety protection, circuit switching and the like.

The relay is triggered by adopting the movable contact plates in a matched manner, so that the linkage consistency and stability between the movable contact plates are one of the guarantees that the relay can work normally.

At present, the movable contact plates in many relays are purchased and installed by single parts, and the whole connection is weaker, namely the switching synchronism is poorer.
