Description
Technical field
The present invention relates to relay, it is specifically a kind of compression spring of relay of spring structure with pressure and includes the compression spring
Pusher relay.
Background technology
Basic control assembly of the relay as electrical system, has obtained generality application on electromechanical equipment.It is existing after
The various structures of electric appliance also include pusher relay among these.
It is shown in Figure 1, existing pusher relay mainly by pedestal 1, be arranged on pedestal 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 pedestal 1, the coil 2 being sleeved on iron core 3,
The armature 4 that be arranged in the yoke 5 of 2 side of coil, is arranged on yoke 5 with See-saw effect and apply bullet at 4 back side of armature
The compression spring 6 of spring force forms.Its operation principle is about, when at 7 both ends of leading foot of coil 2 plus electric current, the excitatory electricity of coil 2
Stream can generate magnetic flux, and magnetic flux forms magnetic circuit by the working gas gap between iron core 3, yoke 5 and armature 4, and is produced in working gas gap
Raw electromagnetic attraction;When excitation current rising reaches a certain value, electromagnetic attraction torque will overcome the bullet of the movable contact spring of contact portion
Property countertorque, rotate armature 4, so as to drive push rod 8 promote contact portion movable contact spring 8, realize that the contact of contact portion is closed
It closes;When excitation current is reduced to certain value, the elastic reaction square of contact portion movable contact spring is more than electromagnetic attraction torque, armature 4
Original state is returned to, the contact of contact portion disconnects.In the entire See-saw effect action of armature 4, compression spring 6 exists to armature 4
/V is carried out in rotation process, prevents armature 4 from departing from yoke 5.Thus, compression spring is on the relay including foregoing relay
Important composition component, it is desirable that it does not need only to have certain elastic compression power, and the pressing force should not be too large, and otherwise can
Frictional resistance is applied to the rotation of armature, influences the mechanical life of relay.The mechanical life of relay refers to, in coil pin
End applies rated voltage, and tip side does not apply load, and make-to-break ratio is arranged to 300 beats/min, and continues to monitor product action 100
~1,000 ten thousand times(The requirement of different series product mechanical life is different), confirm whether its electric parameter is qualified.
At present, in the structure design of relay, generally there are two types of modes for the structure design of compression spring.
First, the compression spring of elasticity is directly riveted on yoke, the through hole passed through for compression spring is offered on armature(See figure
Shown in 1;Alternatively, see Publication No. CN2382124, the Chinese patent literature that publication date is on June 7th, 2000).This mode is not only
Yoke is easy to cause to deform in riveting process;Moreover, the armature difficulty of processing increase of perforate, while entire relay
Assembling difficulty also increases(The elastic pressuring spring that will be riveted on yoke is needed to be passed through out of armature perforate, and makes the end of compression spring
It withholds at the armature back side);In addition, the pressing force that the compression spring of this mode applies armature is bigger, armature can be caused to rotate
It is subject to the larger resistance of compression spring in the process.These factors can cause molding relay mechanical parameter it is unstable, and then
The mechanical life of relay is caused to seriously affect.
Second, the compression spring of elasticity is arranged on pedestal, /V is carried out to the armature assembled on pedestal(See Publication No.
CN101777460, the Chinese patent literature that publication date is on July 14th, 2010).This mode is usually to be fixed on compression spring unilateral side
It is not only higher to the assembly technical requirement of part on pedestal;Moreover, plastics bits are easily generated, in order to solve asking for plastics bits
Topic, it will usually be fixed at the inserting position of compression spring with dispensing, can so increase the manufacture cost of relay again.
In conclusion the design structure of existing compression spring causes it to there is technical issues that shaping difficulty is big, assemble difficulty,
It is unfavorable for the mechanical parameter stability of effective guarantee application relay, there is direct unfavorable shadow to the mechanical life of relay
It rings;In addition, the manufacture cost of relay can be increased.
