Abstract
The utility model relates to an electromagnetic button, which is used for an electrical system. The electromagnetic button comprises a casing composed of an installing seat and a base, a button, a reset spring, a movable contact bridge, and a fixed contact head. The internal side of the internal chamber of the casing is provided with a coil and an iron core, and two wire connecting pins of the coil are arranged on the external side of the casing. The utility model makes a switch of the button and the small relay combined into integration. The electromagnetic button not only can have performance of the switch, but also can have the performance of the relay, and the electromagnetic button can act protecting functions of the relay. The utility model can bring convenience to layout and installation of an electric system element, and installation area of the layout can be reduced.
Description
The utility model relates to the push-button switch that a kind of electrical system is used, and particularly a kind ofly has solenoid and has the Electromagnetic push-button of power-off protection function.
In the prior art, the housing, button, back-moving spring, the movable contact bridge that constitute by mount pad and pedestal of push-button switch and stationary contact is first-class forms.They only have switch performance.
The purpose of this utility model is to provide a kind of Electromagnetic push-button, not only has the push-button switch performance, and has relay performance, thereby has power-off protection function.
For achieving the above object, the utility model adopts following technical proposals: the same housing, button, back-moving spring, movable contact bridge and the fixed contact that is made of mount pad and pedestal that include with prior art of the utility model.It is characterized in that positioned coil and iron core in the housing inner chamber; Two leg of coil are positioned at hull outside.Push-button switch and miniature relay are combined into one.
Above-mentioned coil is settled in the yoke, and button is supported on the armature, and the upper end of armature bearing two tabular push rods in front and back, the lower end of two push rods is supported on the rear and front end of a block pressur plate, and pressing plate is supported on the upper end of movable contact bridge top stage clip.With outer conductor two leg and a pair of fixed contact of coil are connected; when pressing the button; promote the movable contact bridge through armature, push rod, pressing plate and stage clip and contact fixed contact realization energising downwards; thereby make coil electricity; iron core holds armature, so when release button, switch still is in closure state; when outage; coil losing electricity, iron core no longer hold armature, under action of reset spring; switch opens; even send a telegram here, switch still is in opening, plays the power-off protection effect again; have only to click button again, switch could be closed again.Behind the coil electricity, can establish a push-button switch in addition and control its outage, then contact just disconnects.
The utility model has following conspicuous advantage compared with prior art: this Electromagnetic push-button is combined into one push-button switch and little relay, and is little but have switch performance, and has relay performance, can play the power-off protection effect.The utility model brings convenience for the layout and the installation of electrical system element, can dwindle the layout erection space.
Accompanying drawing is the structural representation of an embodiment of the utility model.
An optimum implementation of the present utility model is: referring to accompanying drawing, this Electromagnetic push-button includes housing, button 1, back-moving spring 12, movable contact bridge 10 and the fixed contact 11,13 that is made of mount pad 4 and pedestal 9, positioned coil 5 and iron core 17 in the housing inner chamber, two leg 6,16 of coil 5 are positioned at hull outside.Coil 5 is placed in the yoke 8; Button 1 is supported on the armature 18, and armature 18 is supported on the upper end of the two tabular push rods 17 in front and back, and the lower end of two push rods 17 is supported on the rear and front end of a block pressur plate 15, and pressing plate 15 is supported on the upper end of movable contact bridge 10 top stage clips 14.The two tabular push rods 17 in described front and back are placed in the groove of pedestal 9 front and back inwalls, can stably move up and down (not shown) by the groove guiding.Stage clip 14 lower ends are three movable contact bridges 10 and the three pairs of fixed contacts 11,13 side by side in corresponding below side by side, and this is applicable to three-phase alternating current electricity consumption occasion.Between movable contact bridge 10 and the back-moving spring 12 insulation spacer is arranged.Preceding nut 2 of plate and plate back nut 3 are arranged at mount pad 4 tops, then this Electromagnetic push-button can be fixed on the electrical system control board.Button 1 head is placed in preceding nut 2 head cavities of plate.
