Description
Technical field
The utility model relates to a kind of electromagnetic relay, is specifically related to a kind of miniature electro-magnetic relay.
Background technology
At present, along with the development of low-voltage electrical apparatus, the application of electromagnetic relay is more and more extensive, also more and more higher to the requirement of electromagnetic relay.Traditional Design Mode is costly, the cycle is long, and temperature rise during electromagnetic relay steady operation is electromagnetic relay design produce in an important parameter, directly affect stability and the life-span of electromagnetic relay.But the structural design of the armature of existing electromagnetic relay is unreasonable, cause the suction-combining force of iron core to armature more weak, and the small volume of this armature, be unfavorable for heat radiation, thus cause the less stable of existing electromagnetic relay.And the internal structure design of existing electromagnetic relay is not compact, thus cause its anti-seismic performance poor.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides that a kind of compact conformation, anti-seismic performance are good, the miniature electro-magnetic relay of stable performance.
For achieving the above object, the utility model adopts a kind of miniature electro-magnetic relay, comprise base plate, the case be connected with base plate buckle, iron core, coil, bobbin, yoke, armature, movable contact spring, static contact spring piece, described yoke is L-type, and the side of this yoke arranges two is separately fixed at yoke pin on base plate, the upper end of described yoke is provided with locating groove, one end of described armature is installed in the location notch on yoke, and described armature is identical with the width of yoke, the centre of described movable contact spring is provided with U-shaped hole, the both sides place in the corresponding U-shaped hole of described armature is provided with fixing lug boss, described movable contact spring is fixed in two fixing lug boss on armature, and the U-shaped hole of described movable contact spring is upper, lower two ends extend formation moving contact end and electric connecting terminal respectively, and described electric connecting terminal is fixed on two boss of yoke.
The beneficial effects of the utility model are: this miniature electro-magnetic relay is by being improved the structure of the armature of existing electromagnetic relay, the width of armature and yoke is set to formed objects, increase the mating surface between armature and iron core, add the magnetic flux density in magnetic circuit, thus enhance the suction-combining force of iron core to armature, and after the increase of the volume of armature, also heat radiation is convenient to, improve stability and the useful life of this miniature electro-magnetic relay, and the centre of movable contact spring is provided with U-shaped hole, the movable contact spring of this vibrational power flow has good springiness, the advantage that fatigue resistance is high, and this movable contact spring is fixed on armature and yoke by multiple spot, this structural design is compact, and anti-seismic performance is good.
