Abstract
The utility model discloses an autolock contactor without energy consumption, relating to the autolock running gear without energy consumption which takes the electric energy as the control device, such as the contactor, the relay, the magnetic starter, etc. The utility model comprises the contact part of a contactor, a magnetic system and the claw of an electromagnetic lock. After the contactor is electrified and attracted instantly, the claw of an electromagnetic lock automatically buckles the contactor. After power cut, the coil of the contactor still keeps the working condition. The contactor does not consume the electric energy and produce the noise during operation. With electric energy saving, reliable operation and no noise, the utility model reduces the accident and prolongs the service life of the equipment.
Description
The present invention relates to contactor, relay, magnetic starter etc. and make the no energy consumption self-locking running gear of control appliance with electric energy.
Known contactor, relay, magnetic starter make its armature adhesive by the magnetic force that hot-wire coil produces at work, and conductive contact is switched on thereupon closure.Keep its work, magnet coil will consume certain electric energy, and energising also easily produced fault when coil was long, and adhesive is bad can to produce electric and magnetic oscillation noise, loose contact easy burn-out contact.
The objective of the invention is to design a kind of contactor, relay, magnetic starter of making under the condition that does not influence original performance, magnet coil in service is the no energy consumption self-locking contactor of consumed power not again.
Solution of the present invention is a kind of no energy consumption self-locking contactor, comprise relay, magnetic starter, have existing conductive contact parts, magnetic system and the electromagnetic lock jaw system that increases newly, magnetic system is made up of former insulating base (1), static iron core (2), divided magnetic ring (3), armature (4), coil (5), armature bracket (6), portal frame (7), insulation rotating shaft (8) etc.It is characterized in that the electromagnetic lock jaw system is made up of the coil (12) of lock pawl armature (10), the terminal block (11) of lock pawl iron core frame (9), band pawl, ribbon core, back-moving spring (13) etc.
In the technology of the present invention solution:
Lock pawl iron core frame (9) is fixed on the insulating base (1) with screw.
Coil of ribbon core (12) and terminal block (11) are installed on the lock pawl iron core frame (9).
The lock pawl armature (10) of band pawl is lived with lock pawl iron core frame (9) strand and is connected.
The lock pawl of the lock pawl armature (10) of band pawl is corresponding with the front end of armature bracket (6).
Back-moving spring (13) is assemblied on the lock pawl iron core frame (9) by the sliding bar (14) of being furnished with adjusting nut (15).
Pawl point on the lock pawl armature (10) of band pawl is equipped with roller (16).
Whole lock pawl iron core frame (9) is contained on the contactor insulating base (1), the front end of static iron core (2), the lock pawl armature (10) of band pawl is corresponding with the armature bracket (6) on the contactor, when the adhesive of contactor magnet energising armature (4), the pawl on the lock pawl armature of electromagnet (10) fastens armature (4) automatically it can not be takeoff.
The lead-in wire of the coil (12) on the lock pawl iron core frame (9) inserts the control corresponding power supply by terminal block (11), when needs make armature (4) and static iron core (2) on the contactor magnet when separating, as long as feed low-voltage DC (direct current available backup battery or supply with through methods such as ac buck rectifications) for the coil (12) of the ribbon core on the lock pawl iron core frame (9), coil (12) produces lock pawl armature (10) that magnetic force will the band pawl and inhales and move.Owing to have roller (16) on the pawl point to slide to make the lock pawl to disengage armature bracket (6) on the device, after losing braking, armature (4) takeoffs, and make it with the contact system action of its interlock and cut off the electricity supply.
No energy consumption self-locking contactor, can increase corresponding mechanism in order to manually by closing, manually break power supply, as long as the sliding bar (14) on the pulling lock pawl (10) also can make the contactor action.
Existing assist control contact (often open, normally closed contact) and the combination of external protection equipment on lock pawl iron-core coil (12) and the contactor still can realize automatic control, remote control and various protection, and increase no energy consumption self-retaining function.
Adopt no energy consumption self-locking mode, changed the operational mode that solenoid on original contactor, relay, the magnetic starter needs long-time energising, make them in use more flexible, save electric energy, remove noise, the minimizing accident, prolong equipment life.
Following accompanying drawing has been described two embodiment of the present invention.
Fig. 1 is a kind of end view among the present invention.
Electromagnetic lock pawl iron core frame (9) is fixed on the front end of the static iron core (2) on the contactor insulating base (1) with screw.
