Abstract
Disclosed in the utility model is a heating cable having a water-resistant function. The heating cable is characterized in that the cable comprises a nichrome alloy conductor as a thermal wire and a copper conductor as a cold wire. Silicone rubber insulation layers for insulation are coated on the surfaces of the nichrome alloy conductor and the copper conductor; a polyester tape is wrapped at the outer sides of the nichrome alloy conductor and the copper conductor; the space between the polyester tape and the silicone rubber insulation layers is filled with a water-blocking filling layer; a composite alumunium-plastic tape successively formed by an alumunium film layer, a glue layer and a polyester film layer is coated at the outer surface of the polyester tape; and a sheath layer is coated at the outer surface of the composite alumunium-plastic tape. According to the heating cable having the water-resistant function provided by the utility model, the water-resistant property of the cable is substantially enhanced; a water soaking phenomenon of the cable core due to the water contact of the cable during the using process can be avoided, thereby reducing the potential safety hazard and prolonging the service life of the cable.
Description
Technical field
The utility model relates to field of cables, is specifically related to a kind of heating cable with water-proof function.
Background technology
Heating cable utilizes the nichrome conductor to carry out heating power, reach the effect of heating or insulation, heat energy is passed to heated body by the mode of heat conduction (convection current) with the far-infrared radiation mode of the 8-13um that sends, on the one hand, mainly apply to residential architecture, road snow melt, eaves roofing snow melting ice-melt etc., on the other hand, mainly be used in interior decoration, the underfloors such as bedroom, parlor and toilet that are laid in are by being the heat energy heating to electric energy conversion.Be solid resistance wire conductor after insulating exruded, then use composite band wrapped, carry out at last sheathing.In the long-term use procedure of existing product, on the one hand, insulation is easily worn out, the phenomenon of be full of cracks, reduce the useful life of cable, also easily cause the accidents such as electric leakage, fire, on the other hand, cable is in moist the chance in the water environment for a long time, cable is easily intake, and potential safety hazard easily occurs, affects the cable physical life.
Because the above-mentioned use limitation of cable, in dwelling house or large public building (Basketball hall, the football shop etc.) interior decoration, cable laying is exposed to exterior portion without any under the safeguard procedures, in case aging, as to chap and intake phenomenon, easily cause security incident, and need to dismantle floor etc. when repairing, from newly laying, cost is larger.
Summary of the invention
The utility model purpose provides a kind of heating cable with water-proof function, this heating cable with water-proof function strengthens the water resistance of cable greatly, the cable core water inlet phenomenon of avoiding cable in use to cause because touching water, reduce potential safety hazard, prolonged the useful life of cable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of heating cable with water-proof function, it is characterized in that: comprise one as the nichrome conductor of thermal wire and the copper conductor of a cold wire, this nichrome conductor and copper conductor surface all are coated with the silicone rubber insulation layer as insulation, one polyester belt is wrapped in described nichrome conductor and the copper conductor outside, be filled with the packed layer that blocks water between described polyester belt and the silicone rubber insulation layer, successively by aluminum film layer, the aluminium-plastic tape that glue layer and laminated polyester film form is coated on the polyester belt outer surface, and a restrictive coating is coated on described aluminium-plastic tape outer surface.
Further improve technical scheme in the technique scheme as follows:
1, in the such scheme, one is covered with the copper conductor of tin layer between described polyester belt and aluminium-plastic tape as ground connection and plated surface.
2, in the such scheme, described copper conductor forms by the multiply tinned copper wire is stranded.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utlity model has the heating cable of water-proof function, greatly strengthen the water resistance of cable, the cable core water inlet phenomenon of avoiding cable in use to cause because touching water has reduced potential safety hazard, has prolonged the useful life of cable; Secondly, overcome the defective of the easy phenomenon that wears out, chaps of existing like product insulation, thereby avoided the cable partial fracture, reduced potential safety hazard, prolonged the useful life of cable.
Description of drawings
Accompanying drawing 1 is for the utlity model has the heating cable structural representation of water-proof function.
In the above accompanying drawing: 1, nichrome conductor; 2, copper conductor; 3, silicone rubber insulation layer; 4, polyester belt; 5, aluminium-plastic tape; 51, aluminum film layer; 52, glue layer; 53, laminated polyester film; 6, restrictive coating; 7, copper conductor; 8, the packed layer that blocks water.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: a kind of heating cable with water-proof function, comprise one as the nichrome conductor 1 of thermal wire and the copper conductor 2 of a cold wire, this nichrome conductor 1 and copper conductor 2 surfaces all are coated with the silicone rubber insulation layer 3 as insulation, one polyester belt 4 is wrapped in described nichrome conductor 1 and copper conductor 2 outsides, be filled with the packed layer 8 that blocks water between described polyester belt 4 and the silicone rubber insulation layer 3, successively by aluminum film layer 51, the aluminium-plastic tape 5 that glue layer 52 and laminated polyester film 53 form is coated on polyester belt 4 outer surfaces, and a restrictive coating 6 is coated on described aluminium-plastic tape 5 outer surfaces.
One is covered with the copper conductor 7 of tin layer 4 between described polyester belt 4 and aluminium-plastic tape 5 as ground connection and plated surface.
Above-mentioned copper conductor 7 forms by the multiply tinned copper wire is stranded.
When adopting above-mentioned heating cable with water-proof function, greatly strengthen the water resistance of cable, the cable core water inlet phenomenon of avoiding cable in use to cause because touching water has reduced potential safety hazard, has prolonged the useful life of cable; Secondly, overcome the defective of the easy phenomenon that wears out, chaps of existing like product insulation, thereby avoided the cable partial fracture, reduced potential safety hazard, prolonged the useful life of cable.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection range of the present utility model.
