Abstract
The utility model discloses a contactor relates to electrical components, the concretely relates to contactor structure. Including the shield cover, static contact and moving contact are installed from top to bottom respectively to the shield cover, the moving contact lower part sets up in the through -hole of shield cover bottom, and the moving contact below is provided with the insulating part, is connected with the extension spring between insulating part and the moving contact, the insulating part right side is provided with the lever of a L shape, and lever corner is provided with the pivot as level fulcrum, and lever cross axle tip is articulated with the insulating part, lever montant mid -mounting has a closing electromagnet, and a separating brake spring, separating brake spring force and closing electromagnet suction opposite direction are installed to lever montant top. The utility model provides a current contactor have the poor problem of action reliability.
Description
Technical field
The utility model relates to electric elements, is specifically related to contactor construction.
Background technology
Contactor is divided into A.C. contactor and D.C. contactor, and it is applied to electric power, distribution and electricity consumption.Contactor broadly refers in industrial electro and utilizes coil to flow through current induced magnetic field, makes contact closure, to reach the electrical equipment of control load.The operation principle of contactor is: when after contactor coil energising, coil current can produce magnetic field, and the magnetic field of generation makes fixed core produce the dynamic iron core of electromagnetic attraction attraction, and drive the action of A.C. contactor point, normally-closed contact disconnects, and normally opened contact closes, and both are interlocks.When the coil is de-energized, electromagnetic attraction disappears, and armature discharges suction under the action of the spring, and contact is restored, and normally opened contact disconnects, and normally-closed contact closes.The operation principle of D.C. contactor is somewhat similar with the principle of temperature switch.There is the shortcoming of Reliability of Microprocessor difference in existing contactor.
Summary of the invention
The utility model provides contactor, and the utility model solves the problem that existing contactor exists Reliability of Microprocessor difference.
For solving the problem, the utility model adopts following technical scheme: contactor, comprises radome, and radome is separately installed with fixed contact and moving contact up and down; Moving contact bottom is arranged in the through hole of radome bottom, is provided with insulating part below moving contact, is connected with extension spring between insulating part and moving contact; Be provided with the lever of a L shape on the right side of insulating part, lever corner is provided with the rotating shaft as balance pivot, lever transverse axis end and insulating part hinged; Be provided with a making electromagnet in the middle part of lever montant, lever montant top is provided with a tripping spring, and tripping spring elastic force is contrary with making electromagnet suction direction.
Advantage of the present utility model: structure is simple, reliable in action.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Symbol description in figure: tripping spring 1, making electromagnet 2, rotating shaft 3, flexible conductor 4, insulating part 5, extension spring 6, bellows 7, moving contact 8, fixed contact 9, glass shell 10, radome 11, upper extraction copper bar 12, insulation board 13, lever 14, lower extraction copper bar 15.
Embodiment
By best embodiment, the utility model is described in detail below
.
As shown in Figure 1, contactor, comprises radome 11, and radome about 11 is separately installed with fixed contact 9 and moving contact 8; Moving contact 8 bottom is arranged in the through hole of radome 11 bottom, is provided with insulating part 5 below moving contact 8, is connected with extension spring 6 between insulating part 5 and moving contact; Be provided with the lever 14 of a L shape on the right side of insulating part 5, lever 14 corner is provided with the rotating shaft 3 as balance pivot, lever 14 transverse axis end and insulating part 5 hinged; Be provided with a making electromagnet 2 in the middle part of lever 14 montant, lever 14 montant top is provided with a tripping spring 1, and tripping spring 1 elastic force is contrary with making electromagnet 2 suction direction.
Be provided with lever, during making electromagnet adhesive, lever rotates clockwise, insulating part compression extension spring, and then promotion moving contact contacts with fixed contact; When making electromagnet is separated, under tripping spring effect, lever is rotated counterclockwise, and insulating part is downward, and extension spring pulls moving contact to be separated with fixed contact.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of amplifying out or variation be still among protection range of the present utility model.
