Description
Technical field:
The invention belongs to electric protective component technical field, relate to the disconnected device of a kind of built-in type hot melt, can be widely used in, in various types of heaters, thering is good overcurrent protection function, to prevent the generation of fire or accident.
Background technology:
Fuse is to exceed after setting a period of time according to electric current, and the heat producing with himself makes melt fusing, thereby makes circuit disconnect a kind of current protector; Fuse is widely used in high and low voltage electric distribution system and control system and power consumption equipment, as the protector of short circuit and overcurrent, is to apply one of the most general protection device; When use; fuse using metallic conductor as melt is series in protected circuit; when the electric current (overload or short circuit current) of protected circuit exceedes setting; and after certain hour; the heat fusing melt being produced by melt self disconnects circuit, thereby electric power system, various electrical equipment and household electrical appliance are played to certain protective effect.Fuse generally all has inverse time lag characteristic, and when overload current hour, fusing time is long; When overload current is large, fusing time is short; Therefore, within the scope of certain overload current, recover normal to electric current, fuse can not fuse and can also continue to use, once but electric current is excessive exceedes certain threshold values, and fuse can fuse and cannot reuse.Be applied at present the multiple thermal cut-off in each electric appliances such as hair dryer, electric iron, electric rice cooker, electric furnace, transformer, motor, water dispenser, washing machine, air-conditioning and coffee pot, its structure is mainly made up of melt and fusion tube and the outer part such as filled, while fusing due to melt and between the connecting line of two ends, easily produce high tension spark, and filler is also easily breakdown in the time of high temperature, can not effectively prevent that arcing phenomenon from occurring.The disclosed a kind of thermal cut-off of for example Chinese patent 201220504624.3, it is by being all set with arc extinguishing isolation ceramic body on the upper lead-in wire at thermal fuse-link two ends and lower lead-in wire, to prevent that fuse-link and lead-in wire from producing arcing phenomenon; The disclosed a kind of thermal cut-off of Chinese patent 201310352931.3, is placed in U-shaped outer casing bottom by thermal fuse-link, and on the inner casing of U-shaped shell, pastes one deck arc extinguishing pottery slider, to solve the arcing phenomenon between upper lead-in wire and lower lead-in wire and thermal fuse-link; Thermal cut-off in above-mentioned patented technology does not only fundamentally solve the generation of arcing phenomenon, and can not be preferably in practice and live wire end and zero line side realize general.Therefore the present invention seeks to design the disconnected device of a kind of novel built-in type hot melt, can in each electric appliances and circuit, realize generally, and produces that sparks flying off in all directions can effectively avoid thermal fuse-link fusing time.
Summary of the invention:
The object of the invention is to overcome the shortcoming that prior art exists, seek design a kind of built-in type hot melt device that break is provided, can be common to live wire end and zero line side, and be sheathed with the protective sleeve of fire proofing, can effectively prevent that spark from bursting out and arcing phenomenon.
To achieve these goals, the agent structure of the disconnected device of built-in type hot melt the present invention relates to comprises eduction rod, sleeve, Thermal Cutoffs, lower eduction rod, protective sleeve, terminals and boring, the equal integral type in one end of one end of upper eduction rod and lower eduction rod is fixedly shaped with sleeve, sleeve inside hollows out formula and is shaped with cylindric boring, the two ends of Thermal Cutoffs with terminals respectively with upper eduction rod and lower eduction rod on sleeve fixedly sleeved, the peripheral jacket formula of socket place of terminals and sleeve is fixedly shaped with the protective sleeve of Integral hollow structure, to prevent that Thermal Cutoffs from producing spark and arcing phenomenon while fusing.
The upper eduction rod the present invention relates to and the surface of lower eduction rod are all coated with uniform copper layer and nickel dam successively, and the thickness of copper layer is 1-2um, and the thickness of nickel dam is greater than 2um, carry out temperature control 1000-1100 DEG C brightness heat treatment after nickel plating; Protective sleeve is polybutylene terephthalate (PBT) (PBT) pipe box or high polymer polypropylene (PP) pipe box of hollow type tubular structure, has good in electric, heat insulation, explosion-proof and resistance effect; The diameter of boring is more than or equal to the diameter of terminals, so that Thermal Cutoffs and sleeve are fixedly sleeved.
Compared with prior art, by being drilled with boring in the sleeve on eduction rod, thereby the terminals of realizing Thermal Cutoffs termination socket-connect in the present invention, have solved easily breakdown problem of filler in traditional fuse; According to the instructions for use of joining with live wire or zero line, only need to select the model of Thermal Cutoffs just can realize general in different electrical voltage systems; When the protective sleeve of distinctive fire-retardant material can effectively prevent Thermal Cutoffs fusing, sparks flying off in all directions in generation, to such an extent as to initiation fire; This fuse structure is simple, and principle is reliable, and design science is easy to use, of many uses, low cost of manufacture, environmental friendliness.
