Description

Novel electromagnetic relay

Technical Field

The utility model relates to a novel electromagnetic relay, and belongs to the technical field of electromagnetic relays.

Background

Electromagnetic relays generally consist of an iron core, a coil, an armature, a conductive sheet, and the like. As long as a certain voltage is applied to the two ends of the coil, a certain current flows through the coil, so that an electromagnetic effect is generated, and the armature is attracted to the iron core against the pulling force of the return spring under the action of electromagnetic force attraction, so that the movable contact and the fixed contact (normally open contact) of the armature are driven to be attracted. When the coil is powered off, the electromagnetic attraction force is eliminated, and the armature returns to the original position under the reaction force of the spring, so that the movable contact and the original static contact (normally closed contact) are released. The contact point and the conducting strip are core components of the relay, and the current relay contact point is inclined due to the change of the angle during contact, so that the contact between the contact electricity on the conducting strip and the static spring strip is linear contact, the contact point is unstable during contact, and the relay is abnormal during vibration during use, thereby reducing the practicability of the electromagnetic relay.
