Abstract
The invention discloses a thermal electric switch which comprises a heat conducting metal case with a plunger therein. Liquid of big coefficient of thermal expansion is arranged between the heat conducting metal case and the plunger, and the upper portion of the heat conducting metal case is provided with an insulating sleeve which is provided with an insulating protection shade. The insulating sleeve is higher than the top surface of the heat conducting metal case, the two radial sides of the insulating sleeve are respectively provided with a contact with a conductive bridge thereon, and the conductive bridge is connected with the top end of the plunger and is contacted with the insulating protection shade through a spring. When the thermal electric switch is heated, liquid of big coefficient of thermal expansion heats and expands to push a piston to lift and jack up the conductive bridge which is consequently released from the contacts, then a power source is disconnected, and the power source returns to electrifying state. Hydraulic pressure will not age, thus the thermal electric switch can not break down.
Description
Technical field
The application relates to heat-sensitive electric switch.
Background technology
Heat-sensitive electric switch in the market generally is a bimetallic type, and its weak point is that sheet metal is aging malfunctioning easily, causes electrification.
Summary of the invention
The application's purpose is the deficiency that overcomes existing heat-sensitive electric switch, proposes a kind of aging malfunctioning heat-sensitive electric switch that is not easy.
The application's technical scheme is: it comprises a heat-conducting metal housing, plunger is housed in the housing, add the big liquid of thermal coefficient of expansion between housing and the plunger, insulating case is arranged at heat-conducting metal housing top, has an insulation to ensure cover on the insulating case, insulating case is higher than the housing end face, insulating case radially both sides has the contact respectively, places conducting bridge on the contact, and conducting bridge is connected with plunger top, conducting bridge withstands on by spring and ensures on the cover, and the plunger rising broke away from contact and conducting bridge when heated liquid expanded.
In addition,, ensure that in insulation the adjustment screw is arranged at the cover top, adjust screw and withstand on the spring, adjust different temperature by the pressure of adjusting spring by pressing plate in order to adjust the adaptive temperature of different occasions.
The liquid that thermal coefficient of expansion recited above is big adopts ether, alcohol all can.
The application's good effect is: when thermoswitch was heated, the liquid heating that the coefficient of expansion is big was expanded, and promoted piston and rose, and the jack-up conducting bridge makes it break away from the contact, deenergization, and temperature reduces the back and recovers "on" position.Because hydraulic pressure can not wear out, so can not cause malfunctioning phenomenon.
Description of drawings
Fig. 1 is the front view of the embodiment of the present application.
Among the figure: 1-heat-conducting metal housing; 2-liquid, 3-plunger, 4-insulating case, 5-contact, 6-conducting bridge, 7-insulation protection cover, 8-spring, 9-adjustment screw, 10-pressing plate.
Concrete mode
Further specify technical scheme of the present invention below in conjunction with Fig. 1.
As shown in Figure 1, the application's temperature-sensitive is established by cable and is comprised a heat-conducting metal housing 1, plunger 3 is housed in the heat-conducting metal housing 1, add the big liquid 2 of thermal coefficient of expansion between heat-conducting metal housing 1 and the plunger 3, insulating case 4 is arranged at heat-conducting metal housing 1 top, there is an insulation to ensure cover 7 on the insulating case 4, insulating case 4 is higher than heat-conducting metal housing 1 end face, insulating case 4 radially both sides has contact 5 respectively, be placed with conducting bridge 6 on the contact 5, conducting bridge 6 is connected with plunger 3 tops, and conducting bridge 6 withstands on by spring 8 and ensures on the cover 7, and plunger 3 risings break away from contact 5 and conducting bridge 6 during liquid 2 expanded by heating.
In order to adjust the adaptive temperature of different occasions, ensure that in insulation the screw 9 of adjustment is arranged at cover 7 tops, adjust screw 9 and withstand on the spring 8 by pressing plate 10, adjust different temperature by the pressure of adjusting spring 8.
