Abstract
The utility model provides a temperature fuse with double springs. The temperature fuse comprises discs, a first spring arranged between the discs, a temperature-sensing body arranged at the right side of the discs, an electrode arranged at the left side of the discs, a second spring with one end connected with the electrode, ceramic connected with the other end of the second spring, a pin penetrating through the ceramic, a shell arranged outside the discs, the temperature-sensing body, the first spring, the electrode, the second spring and the ceramic, and a seal arranged at a connection position of the shell and the pin. The two discs, positioned at two sides of the first spring, are divided into a first disc and a second disc, the temperature-sensing body is positioned at the right side of the first disc, and the electrode is positioned at the left side of the second disc. The temperature fuse with the double springs is advantaged by good sensitivity, high reliability, and high safety performance.
Description
Technical field
the utility model relates to a kind of Thermal Cutoffs with dual spring.
Background technology
the annual aggregate demand to minitype fuse in the whole world is 28,000,000,000, and the amount of money relates to 800,000,000 dollars.As long as can say in life and have electric place all to need fuse, market is very large.Existing fuse on the market mostly adopts traditional tubulose melt, is to control electric current by the induction to the magnitude of current, thereby fuse can be assert danger cut-out electric current, the bad phenomenon such as capable of preventing short circuit, burning when the magnitude of current is excessive.Along with appearing on the market and the continuous renewal of household electrical appliance of various high-tech products, traditional fuse is because the problem of its volume and operation principle, more and more can not meet the need of market, because the fail safe of electricity consumption is judged in its induction by the magnitude of current, very large defect is arranged in sensitivity, there will be to a great extent error, reduced reliability, thereby security performance is also decreased.
Summary of the invention
the technical problems to be solved in the utility model just is to provide the Thermal Cutoffs with dual spring that a kind of sensitivity is good, reliability is strong and security performance is high.
for addressing the above problem, the utility model adopts following technical scheme: a kind of Thermal Cutoffs with dual spring, comprise the garden sheet, and be arranged on the first spring in the middle of the garden sheet, and be arranged on the temperature sensor on garden sheet the right, and be arranged on the electrode on the sheet left side, garden, reach the second spring that an end is connected with electrode, and the pottery be connected with the second spring other end, and run through ceramic pin, and be arranged on garden sheet, temperature sensor, the first spring, electrode, the second spring and the outer shell of pottery, and be arranged on the sealing of shell and pin junction; Described garden sheet has two, is positioned at the both sides of the first spring, is divided into the first garden sheet and the second garden sheet; Described temperature sensor is positioned at the right of the first garden sheet; Described electrode is positioned at the second Pian left side, garden.
as preferably, described pin extends to the outside of shell.
as preferably, described the second spring has 2, and symmetry is connected to the two ends of electrode.
the beneficial effects of the utility model are: because the Thermal Cutoffs with dual spring is provided with temperature sensor, the first spring and the second spring, it impels spring to change to control electric current by temperature sense, has advantages of that security performance is high, reliability is strong and sensitivity is good.
The accompanying drawing explanation
by the description of a preferred embodiment of the present invention being carried out below in conjunction with accompanying drawing, it is clearer that technical scheme of the present invention and technique effect thereof will become, and easy to understand more.Wherein:
