Relay

Abstract

The invention discloses a relay which comprises an iron core and a contact spring. A spring is arranged at a lower end of the iron core, one end of the spring is fixed on the iron core, the other end of the spring is connected with an insulating washer, and the contact spring is fixedly arranged on an outer side of the insulating washer. The iron core and the contact spring can relatively move, when a relay coil is electrified, the iron core moves upwards contacts on the contact spring to be contacted with wiring pins, and the spring is arranged between the contact spring and the iron core, so that the contact spring can automatically adjust the contacting angle of the contacts, and reduction of the service life of the relay caused by the contacts in incorrect place is avoided.

Description

technical field [0001] The invention belongs to electronic control devices, in particular to a 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, contact reeds, springs, coil covers, insulating washers, terminal pins, etc. The iron cores and contact reeds of existing relays are fixedly connected, and the iron core cannot be guaranteed due to product errors. The fixed connection between the core and the contact reed is a vertical connection, so the fixed connection often cannot ensure the correct contact position between the contact of the contact reed and the terminal pin, resulting in a reduction in the service life of the relay. Contents of the invention The invention aims at the deficiency of the prior art, and provides a relay, which can make...
