Abstract
A silica gel electric heating wire comprises an electric heating wire, wherein the electric heating wire is spirally wound on a core wire formed by twisting glass silk threads, and a silica gel layer is coated outside the core wire formed by twisting the electric heating wire and the glass silk threads. Compared with the prior art, the utility model, because the heating wire is the heliciform and twines on the glass fiber silk thread uniformly, so than orthoscopic heating wire flexibility good, difficult rupture heat conduction not only evenly but also fast. The glass fiber silk thread is soft, the tensile strength is high, the glass fiber silk thread can preserve heat and play an insulating role, so that the heating wire wound on the glass fiber silk thread is not easy to break, and in addition, the outermost layer is a silica gel layer, so that the heating wire is not easy to leak electricity, is not afraid of folding, is soft and portable, greatly improves the insulating property and prolongs the service life.
Description
Technical field
The utility model relates to a kind of electric heating element, particularly relates to a kind of silica-gel electrothermic line, and it is mainly used in and makes electric blanket, electric pad etc.
Background technology
At present, the thermo electric material of usefulness such as commercially available electric blanket, electric pad mostly is common enamel-cover resistive conductor.This resistive conductor is suitable for the 220V civil power, easy to manufacture because of it, cost is lower, technology is uncomplicated, thereby use is comparatively general, and is folding but this thermo electric material is afraid of, especially to being used for the various electric heating products below 75 ℃, as electric blanket, electric pad, electric heating shoes, electrically heated glove etc., the life-span is short, and is dangerous.
Summary of the invention
The purpose of this utility model is to provide a kind of good insulation preformance, non-frangibility, safe and reliable silica-gel electrothermic line.
The technical scheme that adopts:
A kind of silica-gel electrothermic line comprises heating wire, it is characterized in that described heating wire is wrapped on the heart yearn of being twisted with the fingers by glass wire with spirality, and the external packets of the heart yearn of twisting with the fingers at heating wire and glass wire is covered with layer of silica gel.
The utility model compared with prior art since heating wire in the shape of a spiral shape be wrapped in equably on the glass fibre silk thread, so better than orthoscopic heating wire flexibility, frangibility heat conduction is not only evenly but also fast.Glass fibre silk thread softness, the tensile strength height not only is incubated but also can play insulating effect, make not frangibility of the heating wire that twines on it, in addition, because outermost layer is a layer of silica gel, thereby make this heating wire be difficult for electric leakage, be not afraid of folding, soft satellite, improved insulation property and useful life greatly.
Description of drawings
Fig. 1 is a kind of concrete structure schematic diagram of the utility model.
Embodiment
A kind of silica-gel electrothermic line comprises heating wire 1, and its characteristics are that heating wire 1 is wrapped on the heart yearn 2 of being twisted with the fingers by glass wire with spirality,, the external packets of the heart yearn of twisting with the fingers at heating wire 1 and glass wire 2 is covered with layer of silica gel 3.
Claims (1)
1, a kind of silica-gel electrothermic line comprises heating wire, it is characterized in that described heating wire is wrapped on the heart yearn of being twisted with the fingers by glass wire with spirality, and the external packets of the heart yearn of twisting with the fingers at heating wire and glass wire is covered with layer of silica gel.
