Background
The traditional alloy type temperature fuse is mostly applied to small-power electronic products such as mobile phone chargers, power adapters, small household appliances, electronic toys and the like, and can provide over-temperature protection for the products. In the use process, when overcurrent and overheat occur, if power supply is cut off in time, the damage of battery explosion and the like can be caused, and the property and life safety of people is seriously threatened. However, in order to increase the ampacity and the current capacity of the fuse, the traditional products simply increase the diameter of the cylindrical low-melting-point alloy, and have the following defects:
1) the cylindrical low-melting-point alloy is arranged in the insulating outer shell, and the fluxing agent is arranged around the low-melting-point alloy, so that the fuse can generate high temperature rise when large current flows through the fuse, the service life of a product is influenced, and the function failure of the fuse is caused;
2) the low melting point alloy is in a cylindrical shape, the diameter of the cylindrical shape is increased and limited due to the limited inner space of the fuse insulating shell, and the fuse only has small ampere capacity and through-current tolerance, so that when abnormal extra-large current passes through the fuse, the fuse can generate an explosion phenomenon due to the accumulation of instant heat.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a reasonable in design's alloy type heavy current temperature fuse, improve the fail safe nature of big ampere rated current value temperature fuse, have big ampere capacity and through-flow tolerance, when the temperature fuse of this kind of design is passed through to unusual super-large electric current, fuse self can not produce higher temperature rise, also can not produce the bad phenomenon of explosion because of heat accumulation in the twinkling of an eye.
In order to achieve the above purpose, the utility model adopts the following technical proposal: the device comprises a cosolvent sealing resin bottom shell, a high-temperature resistant insulating shell, a sealing resin top cover and a conductive electrode; the two conductive electrodes penetrate through the sealing resin top cover and are inserted into the high-temperature-resistant insulating shell, the sealing resin top cover is covered above the high-temperature-resistant insulating shell, and the cosolvent sealing resin bottom shell is arranged outside the high-temperature-resistant insulating shell in a wrapping mode; and a low-melting-point alloy plate is fixed between the bottoms of the two conductive electrodes.
Furthermore, the low-melting-point alloy plate is of a rectangular sheet structure.
After the structure is adopted, the beneficial effects of the utility model are that: the utility model provides an alloy type heavy current temperature fuse improves the fail safe nature of big ampere of rated current value temperature fuse, has big ampere capacity and through-flow tolerance, and when the temperature fuse of this kind of design was passed through to unusual extra-large electric current, fuse self can not produce higher temperature rise, can not produce the bad phenomenon of explosion because of heat accumulation in the twinkling of an eye yet.
