Abstract
The utility model discloses an electric heating semiconductive thin film heating element, consisting of an electric heating semiconductive thin film, an electrode, a leading-out wire of electrode and a surface insulation layer; the utility model is characterized in that the electric heating semiconductive thin film is the polytetrafluoroethylene plastics electric heating semiconductive thin film; the electrode consists of a silver paste coating and a copper foil; the silver paste coating, the copper foil and the electric heating semiconductive thin film are also seamed and fastened by thin lines; the insulation layer which is made of hot melt insulation materials in the hot melt way is the closely coated on the heating thin film and the electrode and has the outer layer covered by a reinforced insulation layer. The electric heating semiconductive thin film heating element of the utility model has the advantages that connections of the electrode and the leading-out wire are much more fixed than those of the prior electric heating semiconductive thin film heating element.
Description
Technical field
The utility model relates to the electric heating element technical field, particularly relates to a kind of electric heating semiconductor film heating element.
Background technology
The polytetrafluoroethylplastic plastic electric heating semiconductor film has softness, folding, corrosion-resistant, advantage such as heating is fast, heating is even, energy-conservation, so the planar heat producing body that the polytetrafluoroethylplastic plastic electric heating semiconductor film is made has purposes very widely.But also just owing to the characteristic of polytetrafluoroethylplastic plastic semiconductive thin film, feasible bigger with its difficulty of processing of making heater element, especially the insulation on the installation connection of electrode and heater element surface is more difficult.
The polytetrafluoroethylplastic plastic electric heating semiconductor film heating element generally is made of electric heating semiconductor film, electrode, electrode outlet line and surface insulation layer.The manufacture method of existing polytetrafluoroethylplastic plastic electric heating semiconductor film heating element is: the square matrix material that electric heating semiconductor film is cut into preseting length and width; At the two ends of electric heating semiconductor film square matrix material brush silver slurry, be covered with Copper Foil again as electrode; After treating that the silver slurry solidifies, lead-out wire is welded on the copper foil electrode with scolding tin; Paste adhesive plaster or micarex or materials such as epoxy resins insulation plate or plastic plate as insulation processing with glue or adhesive sticker on electric heating semiconductor film square matrix material two sides again.But the electric heating piece of making like this, between its electrode and the electric heating semiconductor film and the fastness that is connected between outer layer insulation material and electric heating semiconductor film, the electrode not high, phenomenon such as therefore cause easily that the electric heating semiconductor film heating element insulating reliability is poor, electrode and lead-out wire easily come off has seriously influenced the application of electric heating semiconductor film heating element thus.
The utility model content
The purpose of this utility model provides a kind of electric heating semiconductor film heating element, and the fastness that is connected of the insulating reliability of this electric heating semiconductor film heating element, electrode and lead-out wire all obviously improves than existing electric heating semiconductor film heating element.
The technical solution of the utility model is as follows:
A kind of electric heating semiconductor film heating element is by electric heating semiconductor film, electrode, electrode outlet line and surface insulation layer constitute, it is characterized in that described electric heating semiconductor film is the polytetrafluoroethylplastic plastic electric heating semiconductor film, described electrode is made of silver slurry coating and Copper Foil, banded silver slurry coating is positioned at the two ends of polytetrafluoroethylplastic plastic electric heating semiconductor film, Copper Foil posts on silver slurry coating, Copper Foil, silver slurry coating and electric heating semiconductor film three are with fine rule sewn reinforcement in addition, the described insulating barrier tight covering electric heating semiconductor film that to be one deck form with melt process and the hot melt insulating material of electrode, described insulating barrier also has one deck reinforced insulation layer outward.
If electric heating semiconductor film heating element is used for the occasion of working temperature below 80 ℃, then insulating barrier uses ethylene-vinyl acetate copolymer (EVA) hot melt film, and reinforced insulation layer uses the cotton yarn cloth.
If electric heating semiconductor film heating element is used for the occasion of 50 ℃～200 ℃ of working temperatures, then insulating barrier uses polyurethane-hot melt film or polyester hot melting film, and reinforced insulation layer uses epoxy resins insulation plate or plastic plate or polyester sheet or rubber slab or micarex.
The electrode of the electric heating semiconductor film heating element that the utility model provides is made of silver slurry coating and Copper Foil, and again with fine rule sewn reinforcement in addition, so electrode combines firmly the lead-out wire convenient welding with electric heating semiconductor film; Because of melt process insulating barrier that is shaped and the combination of elements compact and firm that is capped, therefore significantly improved the insulation property of heater element on the one hand again, further improved electric heating semiconductor film and electrode and the be connected fastness of electrode on the other hand with lead-out wire.
Description of drawings
Fig. 1 is the structure principle chart of the utility model electric heating semiconductor film heating element.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Present embodiment is used to make electric heating clothes, electric heating cushion etc., 40 ℃～70 ℃ of working temperatures.
As shown in Figure 1, electric heating semiconductor film heating element is by polytetrafluoroethylplastic plastic electric heating semiconductor film 1, silver slurry coating 2, Copper Foil 3, fine rule 4, electrode outlet line 5, insulating barrier 6 and reinforced insulation layer 7 constitute, banded silver slurry coating 2 is positioned at the two ends of polytetrafluoroethylplastic plastic electric heating semiconductor film 1, Copper Foil 3 posts on silver slurry coating 2, Copper Foil 3, silver slurry coating 2, electric heating semiconductor film 1 three uses the fine rule sewn reinforcement, lead-out wire 5 is welded on the Copper Foil 3, insulating barrier 6 is ethylene-vinyl acetate copolymer (EVA) hot melt film, and reinforced insulation layer 7 is a cotton yarn matter cloth.
If electric heating semiconductor film heating element is used for the occasion of 50 ℃～200 ℃ of working temperatures, then insulating barrier 6 uses polyurethane-hot melt film or polyester hot melting film, and reinforced insulation layer 7 uses epoxy resins insulation plate or plastic plate or polyester sheet or rubber slab or micarex.
