Abstract
The utility model provides a spiral winding type safe electric heating line used for manufacturing a safe electric heating cold protective clothing for an electric motor car, and solves the problems that the present electric heating line is easy to break and cause a fire accident. The spiral winding type safe electric heating line comprises an electric heating wire which is coated by a sheath made by an insulated high-temperature-resistant waterproof plastic layer, and is characterized in that: the electric heating wire adopts a copper-based alloy wire which is with an insulated enamelled leather and uses a 48V direct current safe voltage, the electric heating wire is spirally and uniformly winded on a glass fiber core, then the electric heating wire is coated and fixed by the sheath. Compared with the present common enamelled electric heating wire, the structural distribution of the electric heating wire in the utility model is more reasonable; as the electric heating wire is spirally winded on the glass fiber core, the safe electric heating line may have the advantages of softness, break resistance, flame retardation, and uniform and quick heat conduction; as the glass fiber is soft, the safe electric heating line may also have the advantages of high tensile strength and good insulation; and the alloy wire winded on the glass fiber core is not easy to break, thus fire hidden troubles also can be prevented. Therefore, the electric heating line of the utility model has the beneficial effects of good insulating property, no electric leakage, safe and reliable use, softness, and washing fastness, and can be used as the electric heating line for the safe electric heating cold protective clothing.
Description
Technical field
The utility model relates to a kind of heating wire, particularly a kind of spiral wound form safety electric line that is exclusively used in 48V direct current safe voltage.It is mainly used in as thermo electric material and makes electric vehicle safety electric insulated cold wear.
Background technology
At present, be suitable for the common enamel-cover resistive conductor of 22OV civil power, it is mainly used in as thermo electric material and makes commercially available electric blanket, electric pad etc.This enamel-cover resistive conductor, easy to manufacture because of it, use more general.But this thermo electric material is not suitable as the resistive conductor of safety electric insulated cold wear.Because of it is a linear type structure, easy to break, broken string causes fire incident easily, so use dangerous.
The utility model content
The day of the utility model provide a kind of spiral wound form safety electric line of making electric vehicle safety electric insulated cold wear; It has solved easy to break that existing heating wire exists, and broken string causes problems such as fire incident easily, and its structure distribution is reasonable. have softness, anti-folding, fire-retardant advantage; Heat conduction is fast; Good insulation preformance, safe and reliable, can be as the heating wire of safety electric insulated cold wear.
The technical scheme that the utility model adopted is: this spiral wound form safety electric line comprises that with insulation high temperature resistant waterproof plastic layer be the heating wire that crust coats; Its technical essential is: said heating wire adopts the acid bronze alloy silk of the use 48V direct current safe voltage that has the coat of paint that insulate; The heating wire helical form is wrapped on the glass fiber core equably, and suitcase covers fixing in addition then.
Advantage and the good effect that the utlity model has are: because the utility model is mainly used in the spiral wound form safety electric line of making electric vehicle safety electric insulated cold wear; It adopts the acid bronze alloy silk of the use 48V direct current safe voltage that has the coat of paint that insulate; And the heating wire helical form is wrapped on the glass fiber core equably; So compare with existing common enamel-cover heating wire, its structure distribution is more reasonable.Because of being spiral being wrapped on the glass fiber core, so have softness, anti-ly roll over, fire-retardant advantage, heat conduction not only evenly but also fast.Glass fiber is soft, and tensile strength is high, can be incubated again, twines the alloy silk frangible not on it, no disaster hidden-trouble.Because of it is a crust with insulation high temperature resistant waterproof plastic layer, make this heating wire become double hyer insulation again, thus good insulation preformance, leakproof, safe and reliable, it is not afraid of folding, and soft satellite is not afraid of and is washed, can be as the heating wire of safety electric insulated cold wear.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure sketch map of the utility model.
Embodiment
Specify the concrete structure of the utility model according to Fig. 1.The spiral wound form safety electric line that this is used to make electric vehicle safety electric insulated cold wear comprises that with insulation high temperature resistant waterproof plastic layer be heating wire 2, glass fiber core 1, the insulation high temperature resistant waterproof plastic layer 3 that crust coats.Wherein heating wire 2 adopts the acid bronze alloy silk of the use 48V direct current safe voltage that has the coat of paint that insulate, and its sized and length are decided according to the actual requirements, and the thickness of glass fiber core 1 bundle is chosen according to the specification of heating wire 2.With heating wire 2 in the shape of a spiral shape be wrapped in equably on the pre-processed glass fiber core 3, again with insulation high temperature resistant waterproof plastic layer 1 as the crust heating wire 2 that is coated and fixed, promptly process spiral wound form safety electric line.
Claims (1)
1. spiral wound form safety electric line of making electric vehicle safety electric insulated cold wear; Comprise that with insulation high temperature resistant waterproof plastic layer be the heating wire that crust coats; It is characterized in that: said heating wire adopts the acid bronze alloy silk of the use 48V direct current safe voltage that has the coat of paint that insulate; The heating wire helical form is wrapped on the glass fiber core equably, and suitcase covers fixing in addition then.
