The utility model provides a capacitor with the temperature protection function and good safety.
Description
Technical field
The utility model relates to a kind of capacitor, the capacitor that uses in especially a kind of household electrical appliance and the light fixture.
Background technology
The capacitor that in household electrical appliance and light fixture, uses, comprise housing and place the interior independent capacitance element of housing, described independent capacitance element comprises mandrel, capacitor element and two electrode end surfaces, the cross section of described capacitor element is annulus, the middle part of capacitor element is a mandrel, the two ends of described capacitor element connect two electrode end surfaces respectively, and described two electrode end surfaces connect the electric wire of drawing separately; In the prior art, generally do not have temperature protective device, in use, because the variation of environmental condition, particularly in hot environment, when temperature surpassed the ceiling temperature of capacitor design, capacitor element can not bear, and is easy to cause explosion.If power supply can not cut off, will cause serious consequences such as short circuit, even fire, cause bigger property loss, even crisis user's life-span.
In addition, when power supply was cut off, the voltage that is stored in the capacitor element still existed, if the user touches this capacitor, then was easy to generate the problem of electric shock human body.
The utility model content
In order to overcome the deficiency that existing capacitor does not have temperature protection function, has potential safety hazard, the utility model provides a kind of have temperature protection function, the capacitor with temperature protection function that fail safe is good.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of capacitor with temperature protection function; comprise housing and place the interior independent capacitance element of housing; described independent capacitance element comprises capacitor element and two electrode tips; the two ends of described capacitor element connect two electrode end surfaces respectively; described two electrode end surfaces connect the electric wire of drawing separately; at described one of them electrode end surface and to draw the ceiling temperature that is provided with between the electric wire with described capacitor element be the fuse of fusing-off temperature; described fuse is connected with described capacitor element, and described fuse is positioned at housing.
Further, parallel discharge resistance on described two electrode end surfaces, described discharge resistance is positioned at housing.
Further again, the cross section of described capacitor element is circular, and the middle part of described capacitor element is a mandrel, and described fuse is positioned at described mandrel; Certainly, described capacitor element can be flat-shaped or other shapes, and when capacitor element when being solid, fuse is installed in the capacitor element side.
Further, described fuse is the temperature fusible link; Certainly, fuse also can adopt the fuse of other types, for example reducible fuse protection device etc.
The described electric wire of drawing is drawn outside the housing.Or: the described electric wire of drawing connects binding post, and described binding post exposes outside the housing.
Technical conceive of the present utility model is: electrode end surface is connected in series fuse with drawing between the electric wire therein; when the ambient temperature of using exceeds the set point of fuse; the set point of described fuse is the design ceiling temperature value of capacitor element; can fuse automatically; cut off the electricity supply, play the protection capacitor element do not break, incombustible protective effect.
Further, parallel discharge resistance on two electrode end surfaces, behind dump, can fall the tele-release that is stored in the capacitor element in a short period of time, promptly capacitor element is as power supply, and discharge resistance is as load, forming the closed-loop path discharges, the voltage of capacitor element is reduced to zero, solved, the problem of electric shock human body behind the human body touch because capacitor element is charged.
The beneficial effects of the utility model mainly show: 1, have temperature protection function, fail safe is good; 2, effectively avoided the problem of electric shock human body

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See figures.1.and.2; a kind of capacitor with temperature protection function; comprise housing 1 and place the interior independent capacitance element of housing; described independent capacitance element comprises capacitor element 2 and two electrode end surfaces 3; the two ends of described capacitor element 2 connect two electrode end surfaces 3 respectively; described two electrode end surfaces 3 connect separately draw electric wire 4; at described one of them electrode end surface 3 and draw that to be provided with between the electric wire 4 with the ceiling temperature of described capacitor element be the fuse 5 of fusing-off temperature; described fuse 5 is connected with described capacitor element 2, and described fuse 5 is positioned at housing 1.
The cross section of described capacitor element 2 is circular, and the middle part of described capacitor element 2 is a mandrel 7, and described fuse 5 is positioned at described mandrel 7; Certainly, described capacitor element can be flat-shaped or other shapes, and when capacitor element when being solid, fuse is installed in the capacitor element side.
Described fuse 5 is the temperature fusible link; Certainly, fuse 5 also can adopt the fuse of other types, for example reducible fuse protection device etc.
Among Fig. 1, the described electric wire 4 of drawing is directly drawn outside the housing 1; Among Fig. 2, draw electric wire 4 and connect binding post, described binding post is exposed at outward outside the housing 1.
When the capacitor of present embodiment is arranged in hot environment; if ambient temperature surpasses the fusing-off temperature of fuse, because the fusing-off temperature of fuse is the ceiling temperature of capacitor element 2, fuse 5 fuses automatically; cut power supply, play that the protection capacitor element does not break, incombustible effect.
With reference to Fig. 3 and Fig. 4, parallel discharge resistance 6 on described two electrode end surfaces, described discharge resistance 6 is positioned at housing.
Among Fig. 3, the described electric wire 4 of drawing is directly drawn outside the housing 1; Among Fig. 4, draw electric wire 4 and connect binding post, described binding post is exposed at outward outside the housing 1.
Because discharge resistance 6 in parallel on two electrode end surfaces, when power supply disconnected, the tele-release that can will be stored in the capacitor element in very short time was fallen, and voltage is reduced to zero, had eliminated the harm to human body and property, had improved fail safe.
Other structures of present embodiment are identical with embodiment 1 with the course of work.
