Description
Technical field
The utility model is related to relay technical field, the electromagnetism relay of the double lead column pushing blocks of more particularly to a kind of band
Device.
Background technology
The basic functional principle of electromagnetic relay is to convert electrical energy into magnetic energy to be then converted into mechanical energy, be can turn on using machinery
With the controlled circuit of disjunction, the effect of " relay " is realized.
Used as the bridge that input and output are connected in electromagnetic relay, major function is by the rank of magnetic circuit part to pushing mechanism
Iron actuating length passes to movable contact spring, realizes the conversion of contacts status, and it also has concurrently and is dielectrically separated from function simultaneously.So needs fill
Point consideration avoids pushing mechanism during the actuating of relay from occurring, and stuck, the hidden danger such as come off, to improve its action stability.
In the relay design of prior art, the espespecially downward electromagnetic relay of pushing direction, it promotes block header past
Toward being that pushing block afterbody is linked into armature in insertion spring leaf hole, acted by pushing block itself and be oriented to.This structure, although push away
Motion block will not easily be come off or be stuck, but soft flocks is easily produced during pushing block afterbody and armature clamp, promote block header
It is inserted in spring leaf hole or in action process, push card head is also easily scraped with spring leaf hole and produces soft flocks, is not easy to realize certainly
Dynamic makeup is matched somebody with somebody.
Although many products have made design improvement in detail now, such as by the treatment of reed hole flanging, to reduce spring
Film perforation surrounding metal burr.But the around reason of turning over of this foil increased Making mold, and mould and assembling are set
Standby required precision is also higher.
Another electromagnetic relay of prior art is that pushing block is slidably fitted in the mating holes of base, pushing block
Upper end is in contact with armature, and the lower end of pushing block is in contact with movable contact spring, because pushing block is not matched somebody with somebody with armature, movable contact spring clamp
Close, therefore, there is no soft flocks to produce, but, the pushing block of this structure can be interfered with base, be susceptible to pushing block card
Extremely, the phenomenon such as come off, so as to have impact on the stability of the actuating of relay.
Utility model content
The purpose of this utility model is the deficiency for overcoming prior art, there is provided a kind of electromagnetism of the double lead column pushing blocks of band
Relay, by the improvement to the fit structure between pushing block and base, had both eliminated pushing block assembling process and had acted
The drawbacks of journey produces soft flocks, causes that pushing block will not be interfered in action process with base, it is ensured that the actuating of relay again
Stability, it is also, simple with assembling, the characteristics of easily realize Automated assembly.
The utility model solves the technical scheme that its technical problem used：A kind of electromagnetism of the double lead column pushing blocks of band
Relay, including pushing block, armature, movable contact spring and base；The base is divided into upper and lower chamber, the armature by division board
It is separately mounted in the upper and lower chamber of base with movable contact spring；The centre of the pushing block protrudes out be provided with two lead columns downwards, pushes away
Each the protruding out downwards in the both sides of motion block is provided with a promotion convex portion；The division board of the base is provided with two with the pushing block
Lead column slides two pilot holes being engaged respectively, be provided with two allow respectively corresponding promotion convex portion pass through and with promote convex portion
Between have certain interval through hole；The pushing block is arranged on division board by lead column, the upper end of pushing block and armature
It is in contact, the lower end of the promotion convex portion of pushing block is in contact with movable contact spring.
It is linear contact lay, the lower end of the promotion convex portion of the pushing block and movable contact spring between the upper end of the pushing block and armature
Between for point contact.
The lower end of the promotion convex portion of the pushing block is arcuate structure, to cause that the lower end of promotion convex portion of pushing block passes through
It is that point is contacted between arcuate structure and movable contact spring.
The lower end of the promotion convex portion of the pushing block is also connected with a peripheral size connecing more than the sectional dimension for promoting convex portion
Contact portion, to cause that the both sides of pushing block are in I-shape construction, so that increase the creep age distance between movable contact spring and armature, it is described to push away
The lower end of the promotion convex portion of motion block is in contact by the contact site with movable contact spring.
The bottom of the contact site is arcuate structure, with the arc for the lower end of promotion convex portion of pushing block is passed through contact site
It is that point is contacted between shape structure and movable contact spring.
The upper end of the pushing block is plane, with the contact site of pushing block is arcuate structure in the armature, to cause
The upper end of pushing block is linear contact lay using between the arcuate structure and armature of armature.
The lead column is cylindrical structural, and the pilot hole is circular port.
The line between line and two central points of promotion convex portion between the central point of described two lead columns is substantially
Vertically.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is provided with two lead columns as a result of being protruded out downwards in the centre of pushing block, the two of pushing block
Each the protruding out downwards in side is provided with a promotion convex portion, is provided with the division board of base and distinguished with two lead columns of the pushing block
Two pilot holes being engaged of slip, division board be provided with simultaneously two allow respectively corresponding promotion convex portion pass through and with promotion convex portion
Between have certain interval through hole, by pushing block by lead column be arranged on division board on, upper end and the armature phase of pushing block
Contact, the lower end of the promotion convex portion of pushing block is in contact with movable contact spring.This structure of the present utility model, in the middle of pushing block
Two cylindrical type lead columns (if a lead column, can equally there is unstable situation) of position are matched somebody with somebody with the pilot hole of base
Close, realize the guiding movement of pushing block, and be in contact with movable contact spring using the promotion convex portion on pushing block both sides, using on pushing block
End is in contact with armature, the action of armature can be conducted into movable contact spring, realizes being contacting and separating for sound contact, due to promoting
There is gap the promotion convex portion on block both sides with the through hole of base, that is to say, that stretches into base and has been in the promotion convex portion on pushing block both sides
Complete to decontrol state, actuating of relay forces block will not be stuck, and both eliminated pushing block assembling process and action process is produced
The drawbacks of setation is considered to be worth doing, again cause pushing block will not be interfered with base in action process, it is ensured that the actuating of relay it is steady
It is qualitative also, simple with assembling, the characteristics of easily realize Automated assembly.
The utility model is described in further detail below in conjunction with drawings and Examples；But a kind of band of the present utility model
