Abstract
The utility model relates to a magnetic contactor. The end part of a transmission rod is provided with a touching rod which extends outwards. The touching rod is corresponding to a coil with small power and a supporting bracket which are arranged on a base. Both ends of a rotating arm are respectively provided with a moving armature and a cam wheel and are hinged with the supporting bracket through a spindle on the cam wheel. A torsion spring is arranged between the rotating arm and the supporting bracket. The purpose that the coil with small power is used for replacing a coil with large power and work is obtained. Therefore, the magnetic contactor has the advantage that the magnetic contactor can save power.
Description
The utility model relates to a kind of Magnetic contactor, mainly can cover the arc control device of button main contact by being arranged on pedestal one side, be arranged on the pedestal opposite side the static gag bit that coil is housed, be arranged on the static gag bit homonymy pay contact, be arranged on the moving armature on the static gag bit and be fixed on the moving armature and by coupled rotating shaft control main contact, pay the Magnetic contactor that the drive link of contact folding is formed, belong to the electric equipment technology.
Present Magnetic contactor is to move by being subjected to electric coil generation magnetic field to adsorb moving armature, and realizes the closed power supply purpose that realizes of main contact by the transmission mechanism that links to each other with moving armature.But in whole power supply process, coil is in the energising operating state all the time, especially exists the big weak point of self power consumption in big capacity Magnetic contactor.
The purpose of this utility model just provides the little Magnetic contactor of a kind of self power consumption.
Task of the present utility model realizes by following technical measures: in the drive link end away from rotating shaft an outwardly directed touch pole is set, with the corresponding pedestal of touch pole place, be provided with pair coil and the bearing support of its power of quiet rank less than coil power, in bearing support end the cam that one end has arc notch is set away from pedestal, the other end is the pivoted arm on the moving armature fixedly, wherein the axle on pivoted arm and the cam is fixed the back and is hinged by this axle and bearing support, and being provided with between pivoted arm and bearing support can be with the torsion spring of pivoted arm bullet from static gag bit on the winding mandrel.
During use the normally opened contact in main contact or pair contact is received in pair wire loop, when pressing push-button switch moment, coil electricity, moving armature is adsorbed on the static gag bit by coil, the touch pole termination enters in the bearing support by the arc notch on the cam, and coil electricity is paid in the normally open contact adhesive in main contact or pair contact at this moment, the moving armature at coil place is paid in adhesive, and pivoted arm drives cam rotation and makes cam push down touch pole simultaneously.Coil blackout after loosening button, and pay coil by contact self-locking energising.Press stop button when stopping power supply, pay coil blackout, moving armature is resetted by torsion spring effect drive cam rotation, thereby loosens touch pole, and the moving armature on the coil is resetted.
Because the utility model adopts lower-powered pair of coil band for powerful coil working, thereby has the little advantage of self power consumption.Also has simple in structure, the easy advantage of making simultaneously.
Fig. 1 is a structural representation of the present utility model.

Circuit theory diagrams when Fig. 3 is the utility model work.
Fig. 4 is the structural representation of touch pole end in the utility model.
Be further described below in conjunction with the technical characterictic of accompanying drawing the utility model most preferred embodiment.
A kind ofly can cover the arc control device (1) of button main contact, be arranged on paying contact (16) and the static gag bit (14) of coil (15), the Magnetic contactor that is arranged on the moving armature (3) on the static gag bit (14) and is fixed on that moving armature (3) is gone up and is formed by the drive link (2) of connected rotating shaft (17) control main contact, pair contact folding being housed of pedestal (13) opposite side by being arranged on pedestal (13) one sides.
In drive link (2) end an outwardly directed touch pole (4) is set away from rotating shaft (17), locating with the corresponding pedestal of touch pole (4) (13), be provided with pair coil (10) and the bearing support (7) of its power of static gag bit (8) less than coil (15) power, in bearing support (7) end the cam (5) that one end has arc notch is set away from pedestal (13), the other end is the pivoted arm (9) of moving armature (12) fixedly, wherein the axle (6) on pivoted arm (9) and the cam (5) is fixed the back and is hinged by this axle (6) and bearing support (7), and winding mandrel (6) is set between pivoted arm (9) and bearing support (7) upward also can be with the torsion spring (11) of pivoted arm (9) bullet from static gag bit (8).
For touch pole (4) termination is not better blocked by cam (5) by the camber breach on the cam (5), on touch pole (4) termination, be provided with the flexible pin (19) of spring (18).
Claims (2)
1, a kind of by be arranged on pedestal one side can cover the button main contact arc control device, be arranged on paying contact and the static gag bit of coil being housed of pedestal opposite side, be arranged on the moving armature on the static gag bit, and be fixed on the moving armature also by connected rotating shaft control main contact, pay the Magnetic contactor that the drive link of contact folding is formed, it is characterized in that an outwardly directed touch pole being set in drive link end away from rotating shaft, with the corresponding pedestal of touch pole place, be provided with pair coil and the bearing support of its power of static gag bit less than coil power, in bearing support end the cam that one end has arc notch is set away from pedestal, the other end is the pivoted arm of moving armature fixedly, wherein the axle on pivoted arm and the cam is fixed the back and is hinged by this axle and bearing support, and being provided with between pivoted arm and bearing support also can be with the torsion spring of pivoted arm bullet from static gag bit on the winding mandrel.
2, Magnetic contactor according to claim 1 is characterized in that being provided with the flexible pin of spring on the touch pole termination.
