Ultra-thin-type double-sided chamfering heat protector

Abstract

The invention relates to the heat protector technology field and especially relates to an ultra-thin-type double-sided chamfering heat protector. The protector comprises the heat protector and a lead terminal. A thickness of the heat protector is 2mm. A shell of the heat protector is provided with an insulating layer. The insulating layer adopts a double-sided chamfering design. The heat protector adopts a temperature-sensitive and over-current protection design. The lead terminal adopts an outside leakage design. By using the protector of the invention, a thickness requirement to the heat protector during installation is well satisfied. The protector adapts to a miniaturization demand of an electronic product. The shell is insulated. An unique double-sided chamfering design is used so as to guarantee that cooperation is close and a temperature-sensitive speed is rapid and reliable during installation. The heat protector possesses temperature-sensitive and over-current dual protection performance so that safety performance is high. Because of the outside leakage design of the lead terminal, disadvantages that lead detection efficiency of the heat protector is low, a lead selection is not flexible and so on are overcome and different demands of a market are well satisfied.

Description

technical field [0001] The invention relates to the technical field of thermal protectors, in particular to an ultra-thin double-sided chamfered thermal protector. Background technique [0002] There have been thermal protectors on the market, but the volume is too thick; there is also a casing on the thermal protector. The casing itself is not insulated, but an insulating sleeve is installed on the inner wall of the casing, which forms a closed insulating space with the insulating sheet. No, the thermal protector cannot fully contact the battery; there is also a butterfly-shaped bimetal thermal protector or an overcurrent and overheating composite thermal protector on the market, but it does not have dual protection performance of temperature sensing and overcurrent; The leakage design of the lead terminal of the protector has not been reported in the domestic published literature. Contents of the invention [0003] In order to overcome the existing above-mentioned short...
