Description
Technical field
This utility model is related to relay, the stage clip of the relay of specifically a kind of spring structure with pressure, and comprises this
The pusher relay of stage clip.
Background technology
Relay, as the basic control assembly of electrical system, has obtained universality application on electromechanical equipment.Existing continue
The various structures of electrical equipment, also include pusher relay among these.
Shown in Figure 1, existing pusher relay mainly by base 1, be arranged on base 1 and coupled by push rod 8
Magnetic circuit part and contact portion；And magnetic circuit part mainly by the iron core 3 being arranged on base 1, the coil 2 being sleeved on iron core 3,
The yoke 5 being arranged in coil 2 side, the armature 4 being arranged in See-saw effect on yoke 5 and armature 4 back side apply bullet
The stage clip 6 of spring force forms.Its operation principle is about, when leading foot 7 two ends of coil 2 add electric current, the excitatory electricity of coil 2
Stream can produce magnetic flux, and the working gas gap that magnetic flux passes through between iron core 3, yoke 5 and armature 4 forms magnetic circuit, and produces in working gas gap
Raw electromagnetic attraction；When exciting curent rises and reaches a certain value, electromagnetic attraction moment will overcome the bullet of the movable contact spring of contact portion
Property countertorque, so that armature 4 is rotated, thus drive push rod 8 promote contact portion movable contact spring 8, the contact realizing contact portion is closed
Close；When exciting curent is reduced to certain value, the elastic reaction square of contact portion movable contact spring is more than electromagnetic attraction moment, armature 4
Return to original state, the contact of contact portion disconnects.In the whole See-saw effect action of armature 4, stage clip 6 exists to armature 4
Carry out spacing in rotation process, prevent armature 4 from departing from yoke 5.Thus, stage clip is on the relay including aforementioned relay
Important composition part it is desirable to it does not need only have certain elastic compression power, and this thrust is unsuitable excessive, otherwise can
Rotation to armature applies frictional resistance, the mechanical life of impact relay.The mechanical life of relay refers to, in coil pin
End applies rated voltage, and tip side does not apply to load, and make-to-break ratio is set to 300 beats/min, and continues to monitor product action 100
～1,000 ten thousand times（Different series product mechanical life requires different）, confirm whether its electric parameter is qualified.
At present, in the structure design of relay, the structure design of stage clip typically has two ways.
First, being directly riveted on elastic stage clip on yoke, the through hole passing through for stage clip is offered on armature（See figure
Shown in 1；Or, see the Chinese patent literature that Publication No. CN2382124, publication date are on June 7th, 2000）.This mode is not only
It is easily caused yoke to deform in riveting process；And, the armature difficulty of processing of perforate increases, simultaneously whole relay
Assembling difficulty also increases（Need the elastic pressuring spring being riveted is passed through in the perforate of armature on yoke, and make the end of stage clip
Withhold at the armature back side）；In addition, the thrust ratio that the stage clip of this mode is applied to armature is larger, armature can be led to rotate
During be subject to stage clip larger resistance.These factors all can lead to the mechanical parameter of the relay of institute's molding unstable, and then
The mechanical life of relay is caused to have a strong impact on.
Second, being arranged in elastic stage clip on base, the armature that base is assembled is carried out spacing（See Publication No.
CN101777460, publication date are the Chinese patent literature on July 14th, 2010）.This mode is usually to be fixed on stage clip one side
On base, it is not only higher to the assembly technical requirement of part；And, easily produce plastics bits, in order to solve asking of plastics bits
Topic, it will usually be fixed with dispensing at the plug-in mounting position of stage clip, so can increase the manufacturing cost of relay again.
In sum, the design structure of existing stage clip it is existed molding difficulty is big, assembling difficulty is big technical problem,
It is unfavorable for the mechanical parameter stability of the applied relay of effective guarantee, have directly unfavorable shadow to the mechanical life of relay
Ring；In addition, the manufacturing cost of relay can be increased.
