Problems solved by technology

Existing relays mainly include coils, iron cores, elastic metal sheets, springs, coil covers, insulating washers, terminal pins, etc. The iron cores and elastic metal sheets of existing relays are fixedly connected, and the connection between the iron core and the elastic metal sheets cannot be guaranteed due to product errors. The fixed connection of the elastic metal sheet is a vertical connection, so the fixed connection often cannot ensure the correct contact position between the contact of the elastic metal sheet and the terminal pin, resulting in a reduction in the service life of the relay

Abstract

The invention discloses a simple relay comprising an iron core and an elastic metal sheet. The lower end of the iron core is provided with a spring. One end of the spring is fixed on the iron core, and an insulating washer is connected at the other end of the spring. The elastic metal sheet is fixedly arranged at the external side of the insulating washer. The iron core and the elastic metal sheet of the relay are enabled to relatively more. When a relay coil is electrified, the iron core moves upwardly and the contact on the elastic metal sheet is contacted with a wiring pin. The spring is arranged between the elastic metal sheet and the iron core so that the contact angle of the contact of the elastic metal sheet is enabled to be automatically adjusted, and reduction of the service life of the relay caused by wrong position of the contact can be avoided.

Description

technical field [0001] The invention belongs to electronic control devices, in particular to a simple relay. Background technique [0002] Relay is an electronic control device, which is usually used in automatic control circuit, and plays the role of automatic adjustment, safety protection and conversion circuit in the circuit. Existing relays mainly include coils, iron cores, elastic metal sheets, springs, coil covers, insulating washers, terminal pins, etc. The iron cores and elastic metal sheets of existing relays are fixedly connected, and the connection between the iron core and the elastic metal sheets cannot be guaranteed due to product errors. The fixed connection of the elastic metal sheet is a vertical connection, so the fixed connection often cannot ensure the correct contact position between the contact of the elastic metal sheet and the terminal pin, resulting in a reduction in the service life of the relay. Contents of the invention [0003] The invention p...
