Abstract
Provided is an electromagnetic DC energy-saving contactor. A crank connecting-rod metal support is arranged in one side of an electromagnetic system, wherein a small electromagnet is arranged in the upper end of the support, and a support-crank shaft connection hole is arranged in the lower end of the support; a connecting-rod shaft connection hole is arranged in the middle of a crank body; a small prolonged small magnet armature is arranged on the crank body; a shaft-connection universal joint is arranged on a lower armature of the contactor; and a left and right screw adjuster is arranged in the middle of a connecting rod.
Description
Technical field
The utility model designs a kind of electromagnetic type D.C. contactor, especially a kind of electromagnetic type DC power saving contactor.
Background technology
The electromagnetic type D.C. contactor is widely used in the industrial automation control system at present, will keep operation just to need to continue to solenoid power supply, the normal operation that could keep D.C. contactor after the adhesive of common electrical magnetic-type D.C. contactor.This D.C. contactor is because operation needs to keep energising; so electromagnetic system temperature rise; often can cause the life-span of contactor short; they are two years old. and the solenoid of D.C. contactor continues energising, also wastes a large amount of electric energy, if with the electric energy addition of the electromagnetic contactor waste in all electric equipments of the whole nation; it also is a very surprising numeral; therefore designing a kind of electromagnetic type DC power saving contactor, is the present technical issues that need to address, 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 type DC power saving contactor.
The technical scheme in the invention for solving the technical problem is as described below.
A kind of electromagnetic type DC power saving contactor comprises main contacts, auxiliary contact, electromagnetic system.Main electromagnetic coil one side at contactor arranges the crank connecting link metallic support, in the support upper end little solenoid is set, support and crank body shaft-jointed hole are set in the support lower end, at the middle part of crank body the connecting rod shaft-jointed hole are set, at the lower armature of the contactor setting universal joint that is coupling." 1 " manually control, when pressing starting button QA, electromagnetic contactor coil J gets electric, electromagnetic actuation, the auxiliary normally opened contact of main contacts is closed, and little electromagnet gets electric, crank body is driven by main electromagnet and is displaced to top dead centre by connecting rod simultaneously, and crank body prolongs small magnet armature and little solenoid formation magnetic flux returns network, unclamps starting button, main magnetic coil is opened network, the closed operation of little electromagnet holding contact is pressed stop button, the small magnet dead electricity, the crank body disequilibrium, contactor is got back to released state." 2 " automation is controlled and need be filled at the auxiliary relay top one second air of a time-delay time-delay head replacement QA.
Compared with prior art, the utility model is energy-conservation more than 99%, long service life.

Fig. 4 is the utility model linking automation control circuit schematic diagram.
Embodiment
As shown in the figure, a kind of electromagnetic type DC power saving contactor comprises main contacts, auxiliary contact, electromagnetic system.Main electromagnetic coil one side at contactor arranges the crank connecting link metallic support, in the support upper end little solenoid is set, support and crank body shaft-jointed hole are set in the support lower end, at the middle part of crank body the connecting rod shaft-jointed hole are set, at the crank body prolongation small magnet armature is set.At the lower armature of the contactor setting universal joint that is coupling.The effect of universal joint is when keeping the crank body linkage dynamic, can lengthwise movement, and again can transverse movement.The effect of silk adjuster is about arranging on the connecting rod. the adhesive stroke accuracy of fine setting contactor main magnet, the contact pressure after the assurance main electromagnetic coil dead electricity.
