Abstract
The utility model provides a manual reset temperature sensitive controller, which comprises an insulation casing and a positioning sheet arranged on the end face of the insulation casing. An airtight chamber is formed by the insulation casing and the positioning sheet, the positioning sheet is sleeved on a push rod, one end of the push rod is contacted with a bimetal sheet arranged on the positioning sheet, the other end of the push rod is in a cross structure, and a cross rod of a push rod cross is contacted with a movable contact sheet fixed in the chamber. One end of the movable contact sheet is connected with a movable contact in riveting mode, the other end of the movable contact sheet is connected with a movable contact sheet support in riveting mode to form a three-element device, and the movable contact sheet support penetrates through the insulation casing to be fixedly riveted to the inside of the chamber. A fixed contact is located above the movable contact and contacted with the movable contact, the fixed contact is arranged on a fixed contact support in riveting mode, the fixed contact support penetrates through the insulation casing to be fixedly riveted to the inside of the chamber, and the movable contact, the fixed contact and a wiring terminal are integrated.
Description
Technical field
The utility model relates to a kind of overheat protector and uses the responsive to temperature control device, particularly a kind of hand-reset temp sensing controller.
Background technology
In order to protect household electrical appliance, prevent that household electrical appliance from damaging because components and parts are overheated in using, and installs a temp sensing controller in the household electrical appliance of being everlasting.Along with popularizing of household electrical appliance, temp sensing controller is in the household electrical appliance already, especially in the small household appliances, like the most frequently used mechanical temperature-control and electric actuator spares such as water dispenser, water heater, small power electric heaters.And existing overheat protector adopts the rivet connected mode usually with temp sensing controller, and the electrical equipment connecting portion is many, and with bakelite as supporting member; Contact resistance increases, under the situation of energising continuously since plug connector loosening, install bad or riveted joint firm inadequately; Very easily cause the heating of connector; Bakelite shrinks, the controller action temperature drift, thus cause device to burn.
Summary of the invention
The purpose of the utility model is to provide a kind of simple in structure, hand-reset temp sensing controller that the electrical equipment link is few.
The technical solution that realizes the utility model purpose is: the described a kind of hand-reset temp sensing controller of the utility model, and it comprises insulation crust, is arranged on the spacer on the insulation crust end face; Insulation crust and spacer constitute airtight cavity, and spacer is enclosed within on the push rod, and push rod one end contacts with bimetal leaf on being arranged on spacer; The push rod other end is a cross structure; The cross bar of the push rod cross movable contact spring interior with being fixed on cavity contacts, movable contact spring one end and moving contact riveted joint, and the movable contact spring other end and movable contact spring supporting riveted joint form one three components and parts; Movable contact spring supporting pass insulation crust and rivet clasp in cavity on; Fixed contact is positioned at the moving contact top, and contacts with moving contact, and fixed contact is riveted in the fixed contact supporting; Fixed contact supporting pass insulation crust and rivet clasp in cavity on, moving contact, fixed contact become an integral body with binding post.
Fixed contact supports and movable contact spring supports in order effectively to install at limited space internal fixation, in the airtight cavity of insulation crust and spacer formation, is provided with step, and fixed contact supporting and movable contact spring supporting are placed on also passes through the jag rivet clasp in cavity on the step.
The operation principle of the utility model is: when hand-reset temp sensing controller temperature is elevated to bimetal leaf and beats critical temperature; The bimetal leaf kick; Just promote push rod; Make moving contact and fixed contact break off thereby touch movable contact spring, bimetal leaf maintains the tripping state, makes two contacts maintain off-state.Press reset button and promptly reset, circuit is connected, and plug in this moment again, and electric equipment can normally use.
Problems such as the utility model compared with prior art, and is simple in structure, realizes easily, not only easy to use, and cost is lower, and it is many to have solved existing temp sensing controller connecting portion, is prone to heating, and non-ferrous metal is wasteful.
Description of drawings
Fig. 1 is the hand-reset temp sensing controller structural representation of the utility model, and wherein a is a front view, and b is a left view, and c is a vertical view.
Fig. 2 is the hand-reset temp sensing controller work electrical schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, the described hand-reset temp sensing controller of the utility model comprises binding post 11, insulation crust 4, spacer 3, push rod 10, bimetal leaf 2, movable contact spring supporting 9, fixed contact supporting 5, movable contact spring 8, fixed contact 6, moving contact 7, aluminium lid 1.Insulation crust 4 is selected bakelite or plastic casing for use, and the bakelite shell end face is provided with spacer 3, thereby makes bakelite shell and spacer 3 constitute airtight cavity; Spacer 3 is provided with centre bore; Be enclosed within on the push rod 10 through centre bore, push rod 10 1 ends contact with bimetal leaf 2 on being arranged on spacer 3 end faces, and push rod 10 other ends are cross structure; The cross bar of the push rod 10 crosses movable contact spring 8 interior with being fixed on cavity contacts; Movable contact spring 8 one ends and moving contact 7 riveted joints, movable contact spring 8 other ends and movable contact spring supporting 9 riveted joints form one three components and parts, are installed in the cavity on the step that movable contact spring supporting 9 is placed in the bakelite shell and through the jag rivet clasp.Be installed in the cavity on the step that fixed contact supporting 5 is placed in the bakelite shell and through the jag rivet clasp, fixed contact 6 fixing on it contacts with movable contact spring 8 fixing moving contacts 7, buckles aluminium lid 1 with the entire controller good seal in spacer 3 upper ends at last.
Like Fig. 2, when hand-reset temp sensing controller temperature is elevated to bimetal leaf 2 and beats critical temperature, bimetal leaf 2 kicks; Just promote push rod 10; Thereby the cross cross bar of push rod 10 touches movable contact spring 8 breaks off moving contact 7 and fixed contact 6, and circuit breaks off, and after fixing a breakdown, clicks the push rod rear portion bimetal leaf is resetted; Plug in this moment again, and electric equipment can normally use.
