Abstract
The utility model discloses a magnetic latching relay with an iron grating sheet. The magnetic latching relay comprises a base, and a top cover covered on the base, wherein a coil combination is arranged on a right part in the base; a magnetic steel combination is fixed at the middle of the base; a movable spring sheet and a static spring sheet are installed in a slot below the left part of the base; a push sheet is arranged in the base along the inner wall of the upper sidewall; one end of the push sheet is connected with the magnetic steel combination; the end head of the movable spring sheet is connected to the push sheet; and the iron grating sheet is arranged between the movable spring sheet and the static spring sheet. The magnetic latching relay provided by the utility model is capable of accelerating cut-off for a circuit due to the extinguishment of an electric arc, thus ensuring the working stability of the relay, improving the breaking capacity of the relay, and prolonging the service life of the relay.
Description
Technical field
The utility model relates to the relay field, is specially a kind of magnetic latching relay with the iron railings sheet.
Background technology
Development along with World Economics, improving constantly of living standards of the people and quality of life, the quality and quantity of household electrical appliance, communication apparatus, automobile etc. improves constantly, and this just requires better quality, the higher electromagnetic relay of environmental requirement to change, control the circuit in these products.Magnetic keeps magnetic relay mainly input part and output part, to consist of.This two part mainly comprises the moving and static contact spring piece of coil block, pedestal, magnet steel combination, pushing piece, output.The same with the relay of other kinds, circuit is played automatic connection and cutting action.Difference is, the normally closed or normally open of magnetic latching relay is the effect that relies on permanent-magnet steel fully, and the conversion of its on off state triggers and completes by the pulse electrical signal of certain width.
The load of due to magnetic latching relay, bearing in use is larger, easily produce electric arc between moving contact and fixed contact, make the sensitivity of relay minute deenergizing lower, the electric arc that produces between moving contact and fixed contact in working for a long time in addition can strengthen the wearing and tearing of lifting one's head, and seriously reduces the useful life of relay.
The utility model content
The utility model purpose is to provide a kind of magnetic latching relay with the iron railings sheet, to solve the problem that easily produces electric arc between the dynamic and static contact of prior art magnetic latching relay.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
a kind of magnetic latching relay with the iron railings sheet, include pedestal, and cover top cover on pedestal, it is characterized in that: in pedestal, right part is provided with coil combination, be fixed with by fixed card the magnet steel combination that coordinates with coil combination in the middle of pedestal, be provided with a pair of slot in pedestal left part lower sidewalls, movable contact spring with moving contact is installed in one of them slot, the static contact spring piece with fixed contact that coordinates with movable contact spring is installed in another slot, be provided with pushing piece along the upper side wall inwall in pedestal, pushing piece one end and magnet steel are connected, described movable contact spring termination is connected on pushing piece, be provided with the iron railings sheet that is positioned on the movable contact spring direction of motion between movable contact spring and static contact spring piece.
Described a kind of magnetic latching relay with the iron railings sheet is characterized in that: in described pedestal, right part is provided with fixture, and described coil combination is fixed on fixture.
The utility model has the advantages that:
The magnetic latching relay that the utility model provides, be provided with an iron railings sheet that is beneficial to arc extinguishing in the movable contact spring on the movable contact spring direction of motion and the position between static contact, the electric arc that the open circuit of lifting one's head produces is drawn into the iron railings sheet by the iron railings sheet, cooling and the generation cathode effect by the iron railings sheet, accelerate arc extinction and cut off circuit, guarantee the stability of relay work, improved breaking capacity and the useful life of relay.
