As a kind of optimal technical scheme of the utility model, first pin is both provided with absolutely with second pin surface
Edge casing.
As a kind of optimal technical scheme of the utility model, the insulating sleeve injects at least 1.5mm in square shell.
As a kind of optimal technical scheme of the utility model, the alloy is fusible alloy.
Compared with prior art, the beneficial effects of the utility model are：The Thermal Cutoffs of this kind of pin tape insulation casing,
By the alloy set in square enclosure, and alloy is fusible alloy, can perceive the external world by pin and shell
Temperature, when fusible alloy reaches operating temperature, starts to fuse, and is received under the action of special resin to the pin at both ends rapidly
Shorten into spherical, so that circuit loop is cut off, the circuit of cut-out is in insulator pin and seals under the protection of resin, has prevented short
The problem of road, by the special resin set in alloy upper end, can provide fluxing action, so as to be shrunk to alloy is fluxing
Ball, by the sealing resin set in special resin upper end, for carrying out closing protection to it, has by being used on pin
The conducting wire of insulating sleeve, has very high safety coefficient, meanwhile, pin and insulating layer length, line footpath, selection etc. can be according to reality
The problem of using making choice, can making pin that there is insulation protection, avoiding two pins mutual conduction in application, improve electricity
Road and the safety and reliability of product, it is scientific and reasonable for structure, it is safe and convenient to use, provide a great help for people.
