Description
Technical field
The utility model relates to a kind of locker, is 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 RCCB 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 of electrical network is high, burns coil easily, if voltage is low, the adhesive maintenance energy descends and then burns contact easily, and causes switch fault.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide a kind of and can overcome above-mentioned defective, can cut off the power supply automatically, enable manual outage again, the locker of the electromagnetic switch of raising service life of equipment and dependability.
The utility model solves the technical scheme that its technical problem adopted: 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, and an 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, and installing rack is fixed in the housing, and 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 accomplish the 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 through 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 is retreated with latch hook and separated, 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 utility model had is: after moving crane span structure and electromagnetic switch locking, can realize that the coil no power just can guarantee steady closure, the energy that avoids waste, the useful life of improving product.Through the setting of hand lever, automatic disjunction can not only be accomplished and manual disjunction can also be accomplished, meet safety standard more, improve safety in utilization.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1, housing 1 is equipped with moving crane span structure 2 and adhesive electromagnet 7, adhesive electromagnet 7 and moving crane span structure 2 corresponding settings, and housing 1 is provided with locker, and an end of moving crane span structure 2 bottom armature 4 is bent to form latch hook 5, and latch hook 5 is corresponding with locker.Locker comprises installing rack 3, release electromagnet 8, catch 9, hand lever 10 and inserted link 6, and installing rack 3 is fixed in the housing 1, and release electromagnet 8 is arranged on an end of installing rack 3; The moving iron core 13 of release electromagnet 8 is connected with catch 9; Catch 9 connects inserted link 6, and inserted link 6 is corresponding with latch hook 5, and the top of installing rack 3 and catch 9 corresponding positions are provided with hand lever 10; The bottom of hand lever 10 contacts with catch 9, and hand lever 10 first halves are with hand lever spring 11.Hand lever spring 11 conveniently makes hand lever 10 be returned to the origin-location.Moving iron core 13 upper ring caps of release electromagnet 8 have pagoda spring 12.Installing rack 3 is provided with spacing preiection 14, and the position of spacing preiection 14 is corresponding with the position of inserted link 6.Spacing preiection 14 plays the effect to inserted link 6 spacing supports, makes things convenient for the location of inserted link 6, and avoids occurring botching routines, and improves job stability.Spacing preiection 14 is coated with circle wheel 15.Circle wheel 15 directly contacts with inserted link 6, reduces friction and improves comfort and useful life.
