Abstract
The invention discloses a kind of electromagnetic relay structure, the electromagnetic relay structure includes electromagnetic relay ontology and baffle, the baffle from electromagnetic relay shell to electromagnetic relay inside stretch out gear between movable contact spring and static contact spring piece；When electromagnetic relay is attracted, movable contact spring does not contact with static contact spring piece with baffle；When electromagnetic relay discharges, when static contact spring piece rebound is beyond initial position, baffle can inhibit static contact spring piece to be moved to movable contact spring, i.e., static contact spring piece is between initial position and attracted position, will not move to close to movable contact spring side；Electromagnetic relay is under release conditions, and movable contact spring does not contact with static contact spring piece with baffle.The present invention is not under conditions of changing relay original performance parameter, when effectively increasing release movable contact spring between static contact spring piece contact at a distance from, shorten the arcing time, prevented arc reignition phenomenon, the ablation situation for reducing contact, extends the electric life of relay.
Description
Technical field
The present invention is the improvement to existing electromagnetic relay structure.
Background technology
Electromagnetic relay is widely used in automatic control equipment, due to the needs of development in science and technology, it is desirable that relay construction
It is more compact, volume smaller, sensitivity higher, functional reliability higher, while low manufacture cost, longer life expectancy, i.e., it to prevent often
Open contact melting welding extends relay life.Relay suction spring load characteristic will be repaiied by usually promoting the above relay performance
Change, by promoting static contact spring piece rigidity, change the increasing counter-force such as extraordinary size prevents contact from restriking to increase release breaking speed, preceding
Person needs to replace reed material increase cost, and the latter can make becoming large-sized for relay, be unfavorable for the miniaturization of relay.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of electromagnetic relay structures, need not change
In the case of becoming relay dynamic characteristic, it can play and inhibit static contact spring piece release rebound, inhibit arc reignition, prevent contact melting welding
Effect.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of electromagnetic relay structure, including electromagnetic relay ontology, shell are described to stretching out baffle inside electromagnetic relay
Baffle is between movable contact spring and static contact spring piece；When electromagnetic relay is attracted, movable contact spring does not contact with static contact spring piece with baffle；Electromagnetism
When relay discharges, when static contact spring piece rebound is beyond initial position, baffle can inhibit static contact spring piece to be moved to movable contact spring, i.e., at static contact spring piece
Between initial position and attracted position, it will not move to close to movable contact spring side；Electromagnetic relay is under release conditions, is moved
Reed does not contact with static contact spring piece with baffle.
Compared with prior art, the present invention has the advantages that：
The present invention is not under conditions of changing relay original performance parameter, movable contact spring and quiet spring when effectively increasing release
Distance between piece contact, shortens the arcing time, has prevented arc reignition phenomenon, reduces the ablation situation of contact, prolongs
The electric life of relay is grown.
