Description
Technical field
The utility model relates to relay technical fields, and in particular to a kind of two tunnel on-off relay of self-sustaining.
Background technique
Now keep relay electric appliance mainly use magnetic keep and mechanical locking based on, also have the holding of motor type after
Electric appliance.Magnetic latching relay is when having external force vibration, it is possible to the problem of meeting generating state changes, while contact force is not
Enough big, slight change in size will cause the great change of state or pressure, cisco unity malfunction when meeting external magnetic field is interfered.Machine
Tool formula guard relay, its structure is complicated, assembly difficulty, when interfering there is also meeting external magnetic field the problems such as cisco unity malfunction
It is phased out out this market.Other motors are to maintain relay, the disadvantage is that volume is big, at high cost, mechanical life is short dynamic
Make the time it is big a series of problems, such as, seldom pass through simple stable structure realize two tunnel on-off.In addition the control of the above relay
Lead-out wire all uses flexible cord mode, and production technology is complicated, poor reliability.
Utility model content
For the defects in the prior art, the utility model provides two tunnel on-off relay of self-sustaining, is tied using symmetrical expression
Structure ensures that volume is smaller, meets the maximization that installation utilizes space, disconnected while realizing two circuits by motor and
Connection, keeps contact force very big, more stable.Production technology is simpler.
In order to achieve the above objectives, two tunnel on-off relay of self-sustaining provided by the utility model, including shell, motor and biography
Dynamic component；The motor is set to the middle part of the shell, and the output shaft of the motor is equipped with worm screw, the worm screw two sides point
There are not the transmission parts, transmission parts described in two groups are symmetrical arranged；The transmission parts include duplicate gear, sector gear,
Push card, dynamic touch panel and static contact panel；The duplicate gear and the sector gear are rotated by shaft respectively to be fixed, the duplex
One of gear of gear is engaged with the worm screw, another gear of the duplicate gear is engaged with the sector gear,
The sector gear and the rear end of the push card are hingedly arranged, and the front end two sides of the push card are respectively equipped with bayonet；It is described
Dynamic touch panel is oppositely arranged with the static contact panel, the free end of the dynamic touch panel set there are two be respectively cooperating with to the card in the bayonet
Foot, the contact of the dynamic touch panel are set to free end front of the dynamic touch panel, the touching of the contact of the static contact panel in the dynamic touch panel
The setting of head swaying direction interval, the push card push the free end of the dynamic touch panel to make the contact of touch panel close to the stationary contact
The contact of plate.
The technical principle and technical effect of this programme are as follows:
The output shaft of motor rotates, and drives one of gear of two sides duplicate gear to rotate simultaneously by worm screw, due to
Two duplicate gears cooperate with worm screw, therefore will rotate synchronously, another gear of duplicate gear can also rotate synchronously, duplex
Another gear of gear drives sector gear rotation, since rear end and the sector gear of push card are hinged, in sector
During wheel rotation, push card is by reciprocal telescopic movement, and the front end of push card is connect with the free end of dynamic touch panel, therefore
Sector gear to be formed when driving push card close to the free end of dynamic touch panel by the contact of touch panel is contacted with static contact panel
Closure, and then realize connection, fit system of this programme due to using worm screw and gear, can only worm screw as main driving, tool
There is self-locking effect, ultimately forms self-sustaining and move the state that touch panel is connected to static contact panel.The transmission mechanism of two sides is symmetricly set on
The two sides of worm screw, therefore when rotary worm, the touch plate of two drive mechanisms will be realized synchronous connection or be disconnected quiet
Touch panel.
Since the front end of push card is equipped with bayonet, while the free end of dynamic touch panel sets the card base due to bayonet cooperation,
When push card drives dynamic touch panel, the relative angle variation of the two is more flexible, is keeping the same of the transmitting of effective power
When, the independence of the two can be kept, it is easier to drive to dynamic touch panel.
Using gear on worm mechanism, the rotary force of motor is converted into motive force, makes the pressure of contact, is much higher than magnetic guarantor
Relay and mechanical guard relay are held, reaches 500 grams or more.Simultaneously as being the promotion that the invention uses gear on worm
Mechanism, its state will not by external force vibration and change, thus the vibration of external force does not have any influence to it.It can be easily real
Existing automatic assembling and automatic test, greatly improve the efficiency.It, being capable of overtravel work since the structure motive force of use is big
Make, not only increases contact force, and under certain dimensional variations, do not affect its pressure and state.Special biography
