Description
Technical field
This utility model is related to relay, specifically a kind of pusher relay.
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 7
Magnetic circuit part and contact portion composition.Its operation principle is about：When applying electric current at leading foot 10 two ends of coil 2, line
The exciting curent of circle 2 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
Working gas gap produces electromagnetic attraction；When exciting curent rises and reaches a certain value, electromagnetic attraction moment will overcome contact site transfer
The elastic reaction square of reed 8, makes armature 4 rotate, thus driving push rod 7 to promote the movable contact spring 8 of contact portion, realizes contact portion
The closing of contact；When exciting curent is reduced to certain value, the elastic reaction square of contact portion movable contact spring 8 is more than electromagnetic attraction power
Square, the elastic reaction square of movable contact spring 8 returns to original state, the contact of contact portion by the armature 4 that push rod 7 promotes magnetic circuit part
Disconnect.Thus can clearly be seen that：The push rod of pusher relay is magnetic circuit part（Input）With contact portion（I.e. defeated
Go out）Between moment transmission core component.
In the design structure of existing pusher relay, magnetic circuit part armature and contact portion movable contact spring are respectively equipped with
Convergence hole that is mutually corresponding, installing push rod, the two ends of push rod install respectively and are connected to corresponding linking in the hole, i.e. the one of push rod
End install the linking in the hole being connected on armature, the other end installs the linking in the hole being connected on movable contact spring, with this by armature with
Movable contact spring will transmit the push rod clamping position of moment, as shown in Figure 1.Though this design structure can make push rod be reliably achieved magnetic circuit part
Divide the moment transmission and contact portion between, but it has following technical problem underlying：
1. assembling design structure on armature and movable contact spring for the push rod, no matter in assembling or in the military service of finished product,
The joining place of three easily produces more soft flocks because of friction, especially becomes apparent from an assembling process（Large-sized rod member
It is inserted in the space of small distance, easily occur mutual the friction such as scraping, touch）, and then the finished product of relay product can be affected
Quality and service life；
2. movable contact spring certainly will be pushed aside by the longer push rod of length plug-in mounting between the shorter armature of distance and movable contact spring,
Then by corresponding for the push rod linking in the hole being inserted into armature, then the movable contact spring resetting is connected with push rod, the determining of whole process
Position plug-in mounting can only rely on post workman manually to realize, and the difficulty of automatic assembling is very big, and production cost is high.
Content of the invention
Goal of the invention of the present utility model is：Particularity for above-mentioned existing pusher relay and deficiency, provide
A kind of assembling difficulty is little, will not produce soft flocks, be advantageously implemented automatic assembling, finished product stable mechanical performance and reliable push rod
Formula relay.
The technical solution adopted in the utility model is：A kind of pusher relay, including base and be arranged on base
And the magnetic circuit part that coupled by push rod and contact portion；The end that described push rod couples contact portion movable contact spring has the dynamic spring of coupling
The movable contact spring draw-in groove of piece, the end of described push rod connection magnetic circuit part armature has the armature joint of evagination, the bottom of described armature
There is the nick shaped embedding slot of the armature joint on coupling push rod along middle part.
Preferably, the end of described push rod connection contact portion movable contact spring has two being arranged laterally at a spacing and moves
Reed joint, the push rod end face between two movable contact spring joints is the movable contact spring draw-in groove of coupling movable contact spring.
Preferably, the movable contact spring joint of described push rod and/or armature joint are the convex cone structure of column.
Preferably, described base is provided with the installing rack being erected between magnetic circuit part and contact portion, described
Installing rack is ledge structure, has the placement platform supporting push rod, the height of described placement platform towards the surface of contact portion
It is matched with the coupled position height between armature, push rod and movable contact spring three.
Preferably, the promotion of described movable contact spring couples the card holding trough that position has coupling push rod corresponding end.
The beneficial effects of the utility model are：Above-mentioned relay, on the premise of not affecting push rod transmission moment properties, leads to
Cross to push rod two ends end construction and armature bottom along structure optimization design, thus eliminating the linking on armature and movable contact spring
Hole, makes armature " riding " in one end of push rod, and the other end of push rod then " embraces " movable contact spring, this assembling design structure not only makes
Assembling difficulty is little, is advantageously implemented automatic assembling, and then reduces production cost, and, no matter during in assembling or finished product
In military service, at the linking combination between armature, push rod and movable contact spring, all will not produce soft flocks, relay is internal clean, relay
End product quality is high, stable mechanical performance and reliability, long service life, practical.
