Abstract
Provided is an electromagnetic AC energy-saving contactor. A crank connecting-rod metal support is arranged on a protective frame of an electromagnetic system, wherein a small electromagnet is arranged at one end of the support, and a shaft connection hole of the support and a crank body is arranged at the other end of the support; a connecting-rod shaft connection hole is arranged in the middle of the crank body; and a small prolonged magnet armature is arranged on the crank body. A connecting-rod shaft connection hole is arranged in a guard board of a moving magnet of the electromagnetic system, and a left and right thread adjuster is arranged in the middle of the connecting rod.
Description
Technical field
The utility model relates to a kind of electromagnetic AC contactor, especially a kind of electromagnetic energy-saving noise elimination A.C. contactor.
Background technology
In at present electromagnetic AC contactor extensive use and the industrial automation system.To keep operation just to need to power to solenoid after the common electromagnetic AC contactor adhesive, just can keep in touch the normal operation of device, this contactor is because operation needs to keep energising, so electromagnetic system temperature rise, can cause the useful life of contactor short, contactor generation electromagnetic noise in service is polluted operational environment simultaneously.Two, the solenoid of contactor continues energising also wastes a large amount of electric energy.If with the electric energy addition of electromagnetic contactor waste in all electric equipments of the whole nation, also be a very surprising numeral.Therefore designing a kind of electromagnetic AC energy-saving contactor, is a technical problem that needs at present solution, also is a major contribution to energy-conserving and environment-protective.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of electromagnetic energy-saving. the noise elimination A.C. contactor.
The technical scheme of technical problem to be solved in the utility model is as described below.
A kind of electromagnetic AC contactor, comprise main contacts. auxiliary contact. electromagnetic system, in the Electromagnetic System of Contactor protective frame crank connecting link metallic support is set, end at support is provided with little solenoid, at the other end of support the crank body axis hole that is coupling is set, crank body is coupling therewith, and the shaft-jointed hole connecting rod that is coupling is set at the middle part of crank body, and the connecting rod shaft-jointed hole that arranges on the connecting rod other end and the moving magnet backplate is coupling." 1 " manually control, when pressing starting button QA, the electromagnetic contactor coil gets electric, electromagnetic actuation, the main contacts auxiliary contact are closed, little electromagnet gets electric, and crank body is driven by main electromagnet and is displaced to rear stop by connecting rod simultaneously, and crank body prolongs small magnet armature and little solenoid formation magnetic flux returns network.Unclamp starting button, main magnetic coil is opened network, and little electromagnet keeps adhesive, and stop button is pressed in the closed maintenance operation of contacts of contactor, little electromagnet dead electricity, and the crank body disequilibrium, contactor is reflected back to released state." 2 " automation control { at the auxiliary relay top, fills one second air of time-delay time-delay head, replaces QA}.
Compared with prior art, the utility model is energy-conservation more than 99%, noiseless, long service life.

Embodiment
As shown in the figure, a kind of electromagnetic AC energy-saving contactor comprises main contacts. auxiliary contact. and electromagnetic system.In the Electromagnetic System of Contactor protective frame crank connecting link metallic support is set, end at support is provided with little solenoid, the other end at support arranges the crank body shaft-jointed hole, crank body is coupling therewith, the shaft-jointed hole connecting rod that is coupling is set at the middle part of crank body, and the pitman shaft spindle hole that arranges on the connecting rod other end and the moving magnet backplate is coupling.The effect of silk adjuster is the adhesive stroke accuracy of fine setting contactor main magnet about arranging on the connecting rod, the contact pressure after the assurance main electromagnetic coil dead electricity.
