Description
Technical field
The present invention relates to a kind of locker, be specifically related to a kind of locker of electromagnetic switch.
Background technology
Electromagnetic switch is a kind of power supply unit, supply line to be implemented the on-off function device, and is simple in structure because of it, send advantage such as electricity automatically, not only can be used as circuit breaker but also can be used as residual current circuit breaker or the automatic phase diverter switch.
Electromagnetic switch in use because coil is in "on" position all the time during its work, if the voltage height of electrical network burns coil easily, if voltage is low, the adhesive maintenance energy descends and then burns contact easily, and causes switch fault.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of and can overcome above-mentioned defective, can cut off the power supply automatically, can manually cut off the power supply again, improve the locker of the electromagnetic switch of service life of equipment and dependability.
The technical solution adopted for the present invention to solve the technical problems is: the locker of described electromagnetic switch, comprise the moving crane span structure and the adhesive electromagnet that are installed in the housing, the corresponding setting of adhesive electromagnet with moving crane span structure, it is characterized in that: housing is provided with locker, one end of moving crane span structure bottom armature is bent to form latch hook, and latch hook is corresponding with locker.
Described locker comprises installing rack, release electromagnet, catch, hand lever and inserted link, installing rack is fixed in the housing, release electromagnet is arranged on an end of installing rack, the moving iron core of release electromagnet is connected with catch, catch connects inserted link, and inserted link is corresponding with latch hook, and the corresponding position of the top of installing rack and catch is provided with hand lever, the bottom of hand lever contacts with catch, and the first half of hand lever is with the hand lever spring.The hand lever spring conveniently makes hand lever reply.
Be with pagoda spring on the moving iron core of described release electromagnet.
Described installing rack is provided with spacing preiection, and the position of spacing preiection is corresponding with the position of inserted link.Spacing preiection plays the effect to the spacing support of inserted link, makes things convenient for the location of inserted link, and avoids occurring botching routines, and improves job stability.
Described spacing preiection place is coated with circle wheel or bearing.Circle wheel or bearing directly contact with inserted link, reduce friction and improve comfort and useful life.
During use, the energising of starting relay control adhesive electromagnet moves down and the adhesive electromagnetic actuation crane span structure, and then makes the dynamic and static closing of contact of earth leakage protective device.Moving crane span structure is its bottom armature extruding inserted link in folding process, and inserted link at first pushes pagoda spring and retreats, move down into the position of inserted link when latch hook after, pagoda spring is released inserted link and is made inserted link insert latch hook to finish locking to moving crane span structure.Make adhesive electromagnet outage this moment, under the effect of inserted link and latch hook, moving crane span structure can't on move, switch is in "on" position all the time.
During disjunction, release electromagnet energising action drives its moving iron core and moves backward, and moving iron core drives inserted link by catch and retreats, and inserted link separates with latch hook, and moving crane span structure moves upward under the effect of housing spring, drives moving contact and separates with fixed contact.When needing manual separation, break hand lever off with the fingers and thumb, hand lever compressing catch moves backward, and catch drive inserted link retreats with latch hook and separates, and moving crane span structure moves upward under the effect of housing spring, realizes disjunction.Realizing to realize manual separation again under the situation of separating automatically.
The beneficial effect that the present invention had is: can realize that the coil no power just can guarantee steady closure after moving crane span structure and electromagnetic switch locking, the energy that avoids waste, the useful life of improving product.By the setting of hand lever, automatic disjunction can not only be finished and manual disjunction can also be finished, meet safety standard more, improve safety in utilization.
