Abstract
The utility model discloses a track-type transmission electromagnetic relay composed of an iron core, a yoke, an armature, a pushing card, a movable reed and stationary reeds. The relay is characterized in that a thickened separator plate is arranged on a base, a round hole track for the pushing card going through is arranged in the middle of the separator plate, the movable reed is arranged between the two stationary reeds, the pushing card is column-shaped, a convex column which can be conveniently inserted into a square hole in the middle of the movable reed is made at one end of the pushing card, and a semicircular top block is made at the other end of the pushing card. According to the utility model, the structure of a conventional electromagnetic relay is reformed, and the pushing type of a transmission part of the conventional relay is changed to be the track type, so that the stability of the transmission part of the relay is improved, and the reliability of products is improved.
Description
Technical field
The utility model belongs to the improvement in electric component manufacturing technology field, particularly electromagnetic relay.
Background technology
Relay is the main electric component of control circuit.Relay operation principle is: after relay coil energising, just produce magnetic flux at yoke, iron core, armature and working gas gap in the magnetic circuit forming.Produce thus electromagnetic attraction, attract armature close to pole-shoe face unshakable in one's determination, electric current in coil reaches certain value (pickup value), when suction is enough to overcome the counter-force of return spring and contact spring generation, armature attracted to the position that pole-shoe face is adjacent to, the motion of drive movable contact spring, makes the sound closing of contact, connects controlled circuit.After coil blackout, electromagnetic attraction disappears, and armature returns to initial position under return spring effect, and original state is also recovered in contact, completes the primary relay course of work.In broad terms, every have electric elements that automatically complete relay characteristic ability, is all called relay.Relay is comprised of three parts:
1, electromagnetic system: be a kind of power conversion assembly that relies on working gas gap and armature electromagnetic energy to change mechanical energy into.2, drive system: it is that the kinetic energy of armature is passed to contact shell and makes relay turn back to the assembly of reset condition.3, contact system: the actuator that is output circuit.
JQX-14 electromagnetic relay is widely used in air-conditioning, field of household appliances, along with the fast development of China's household electric appliances, first of the electrical appliance industry Yi Ju world of China, more and more high in the requirement meeting of output and family's electricity quality.The relay of one of components and parts has also been proposed to higher requirement.As shown in Figure 1, this product electromagnetic system is comprised of iron core, yoke, armature.After coil electricity, iron core, yoke, armature complete magnetic circuit closure.Movable is armature, and armature, with the downward adhesive of fulcrum, orders about push card and is moved to the left.Promote movable contact spring, complete the closure with static contact spring piece.On the termination of running part armature horizontal component, have a square hole, the lower end boss of the push card of both arms rod-type is with regard in patchhole, and armature movement, can make push card move left and right.Two movable contact spring centers have square hole, to the supporting member of push card is inserted.This push card unreasonable structure, has affected the reliability of this product.In application, find that JQX-14 electromagnetic relay retrains because push card boss is subject to space and reed material, that does is very little, coordinates and often to occur that push card deviates from from armature square hole or movable contact spring square hole.After deviating from, cannot recover, cause push card stuck, can not complete normal transmission.Make the reliability of relay can not get ensureing, become the defect that this relay is fatal.
In order to improve this product quality requirement, need improve its push card structure, to improve product reliability.
Summary of the invention
The utility model object is by existing electromagnetic relay structural reform, and changing relay running part push-down is rail mounted.To improve the stability of relay running part, reach the object that improves product reliability.
Rail mounted transmission electromagnetic relay, by iron core, yoke, armature, push card, movable contact spring and static contact spring piece, formed, it is characterized in that base upper spacer is thickening type, and in the middle of dividing plate, be shaped with the circular hole track passing for push card, movable contact spring is between two static contact spring pieces, push card is that column type and one end are shaped with the convenient projection that inserts the middle square hole of movable contact spring, and one end is shaped with semicircle jacking block in addition.
The utility model adopts thickening base upper spacer thickness, and original structure is that dividing plate is thinner narrower, so that push card passes promotion contact from both sides.On dividing plate, have a hole to be considered as track, push card is column type.In penetrating track, in track, be free to slide.After mechanism has assembled, being fixed by track up and down of push card.Front and back are withstood to power by movable contact spring and armature respectively.Its slip is realized by the break-make of mechanism's coil, has fundamentally stopped, because vibrating the hidden danger of bringing.In original structure push card, under, left and right all unrestricted, in cooperation, try to achieve stable.Once because of vibration, will cause one by one push card dislocation, stuck.
