Abstract
The utility model discloses a flexible electric heating plate, composed of heating wires, an insulating layer, and leading wires; the utility model is characterized in that the heating wire is in saw-tooth shape, and the surface of the heating wire is coated with a fiber inner layer and a totally-enclosed rubber outer layer. The flexible electric heating plate of the utility model can bend into any shapes, and the flexible electric heating plate is tightly pressed against a heating object. The utility model has the advantages of convenient operation, high safety, long service life, firm adhesion of heating wires, and non looseness.
Description
A kind of flexible electrothermal sheet belongs to electric heating, and it mainly is made up of heating wire, insulating barrier and lead-out wire.
The electric heating piece of household electrical appliance and industrial use is formed fuse by heating wire, the two sides mica-sheet insulation.A kind of electric heating film is arranged now in the world, as Japanese Ban Kou (Co., Ltd.) electric heating piece, its heating wire be by monoblock exothermic material plate corrode "
" the continuous shape of type, two surfaces are wrapped fiber and are soaked rubber-covered again.
Electric heating piece with mica-sheet insulation is harder, can not bend, process trouble, is careful during use, in order to avoid mica is cracked.The a lot of exothermic materials of waste in the electric heating film forming process can not fastening heating wire behind the fiber impregnation, and heating wire is loosening, and end face seal and insulation property are poor around the electric heating film.
In order to overcome the shortcoming of electric heating film, the utility model flexible electrothermal sheet has proposed a kind of new structure, and fixedly heating wire and double seal insulation can bend to arbitrary surface.
The characteristic of flexible electrothermal sheet is: it has two layers of insulation material above again by zigzag heating wire, and the internal layer of being close to heating wire is an insulating batt, and skin is a rubber insulation.
Flexible electrothermal sheet zigzag heating wire turns to flat filament, silk can strengthen heating area arbitrarily after connecting, and the heating wire shape of electric heating film needs the corrosion of monoblock exothermic material, and different heating areas need be with the sheet materials corrosion of different sizes, thereby waste material, increasing cost.Second benefit of the utility model flexible electrothermal sheet be, the outer layer insulation body rubber is to form through sulfuration, the rubber filling of sulfuration back space between hole and the heating wire between fiber, sulfuration is in aggregates mutually between the rubber.Totally-enclosed heating wire, guaranteed insulation property and airtight performance.Heating wire and insulating barrier connect together securely, can not become flexible, and heating wire is difficult for disconnecting in installing and using process, has guaranteed useful life and reliability, fail safe.
Now with embodiment example explanation flexible electrothermal sheet.
Fig. 1 is the flexible electrothermal sheet outline drawing.
Fig. 2 is the flexible electrothermal sheet cross-sectional view.
Fig. 3 is a flexible electrothermal sheet heating wire structure chart.
(1) is the flexible electrical hot body as seen from Figure 1, and (2) are lead-out wires.The structure of flexible electrothermal sheet is Fig. 2, and zigzag heating wire (3) is (Fig. 3) central, and its upper and lower surface has the glass fibre internal layer (4) of insulation again, on the glass layer and around by silicon rubber insulation skin (5) sealing, after vulcanizing flexible electrothermal sheet.If will increase heating area, a section heating wire caloric value is on demand welded, topped then upper glass fibrage, silicone rubber insulation layer forms through sulfuration again.
Flexible electrothermal sheet is made simple, and is easy to use, because the soft flexibility of rubber and fiber, thereby flexible electrothermal sheet flexural deformation is on demand used.
Claims (2)
1, a kind of flexible electrothermal sheet, by heating wire, insulating barrier and lead-out wire are formed, and it is characterized in that two layers of insulation material is arranged on the zigzag heating wire again, and the internal layer of being close to heating wire is an insulating batt, and skin is totally enclosed rubber insulation.
2, flexible electrothermal sheet according to claim 1 is characterized in that the insulating barrier internal layer is a glass fibre, and insulating outer layer is a silicon rubber.
