Abstract
The utility model provides an electro-thermal film. The electro-thermal film comprises a base film, a metal film, electrodes, etc. The electro-thermal film is characterized in that a top film of a protective sleeve and an upper portion of a bottom film of the protective sleeve form a sealing layer (C) in a heat-sealing manner; a middle portion of an electric wire penetrates through the sealing layer (C); the base film is positioned in a cavity formed by the protective sleeve, a sealing layer (A) and the sealing layer (C). The beneficial effects of the electro-thermal film are that the sealing layer (C) added onto the protective sleeve enables the inside of the protective sleeve to form two cavities which are not communicated with each other; a pulling effect on a cable affects intactness of a sealing layer (B) and damages sealing performance of the cavity formed by the sealing layer (B), the protective sleeve and the sealing layer (C), however, since the electric wire inside the cavity is in a loose state, the pulling effect on the cable does not affect the sealing performance of the electric wire and the sealing layer (C), and thus does not damage the sealing performance of the cavity among the sealing layer (A), the protective sleeve and the sealing layer (B), and the base film is enabled to be always in a vacuum sealing state, thereby substantially improving service life of the electro-thermal film.
Description
Technical field
The utility model belongs to the heating equipment field, relates in particular to a kind of Electric radiant Heating Film.
Background technology
Common Electric radiant Heating Film generally adopts adds sheath outside basal membrane of electrothermal membrane, the burn into of avoiding aqueous vapor to reach the protection basement membrane prolongs the basement membrane purpose in useful life.When making this Electric radiant Heating Film with sheath, need and will be evacuated in the sheath, then the teleblem with sheath adopts the bonding formation sealants of mode such as heat-sealing, the sealing in maintenance film chamber with counterdie.Because the sealant of sheath upper end accompanies cable, in the transportation and use procedure of Electric radiant Heating Film, cable produces slip because pullling with sheath easily, causes sealant the crack to occur, causes film chamber sealing to descend, and reduces the useful life of Electric radiant Heating Film.Pull problem for solving cable, the Electric radiant Heating Film that has is added clips in the outside of cable and sheath junction.But this Electric radiant Heating Film is not and fundamentally solve cable and do not pull problem, and clips also scratches the sheath of Electric radiant Heating Film, the useful life of reducing Electric radiant Heating Film easily in transportation.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of Electric radiant Heating Film, comprise basement membrane, metal film, electrode, sheath, cable, connector, basement membrane is positioned at sheath, metal film is positioned between basement membrane and sheath, epilamellar two electrodes are connected with two wires in the cable respectively, the teleblem of sheath and the heat-sealing of the lower end of counterdie form sealant A, the upper end heat-sealing forms sealant B, sealant B is run through in the cable bottom, the cable upper end is connected with connector, it is characterized in that the teleblem of described sheath and the top heat-sealing of counterdie form sealant C, sealant C is run through at described electric wire middle part, and described basement membrane is positioned at described sheath, in the cavity that forms between described sealant A and sealant C.
The cavity that forms between described sheath, described sealant B and described sealant C is the sealed vacuum chamber.
The beneficial effects of the utility model are: added sealant C at sheath, so that formed two disconnected cavitys in the sheath, the effect of pullling of cable only can have influence on the integrity of sealant B, destroy sealant B, the sealing of the cavity that forms between sheath and sealant C, but because the electric wire in this cavity is in relaxed state, the effect of pullling of cable can not have influence on the sealing of electric wire and sealant C, also just can not be to sealant A, the sealing of cavity causes damage between sheath and sealant B, so that basement membrane is in the vacuum seal state always, significantly promote the useful life of Electric radiant Heating Film.Sealant C processing is simple, making is easy, need not to add other devices in Electric radiant Heating Film, is convenient to its popularization, can not have a negative impact to Electric radiant Heating Film simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Among the figure, 1, basement membrane; 2, metal film; 3, electrode; 4, sheath; 5, cable; 6, connector; 7, electric wire; 8, sealant A; 9, sealant B; 10, sealant C.
As shown in Figure 1, basement membrane 1 is positioned at sheath 4, metal film 2 is positioned at 4 of basement membrane 1 and sheaths, two electrodes 3 on the basement membrane 1 are connected with two wires 7 in the cable 5 respectively, the teleblem of sheath 4 and the heat-sealing of the lower end of counterdie form sealant A8, the upper end heat-sealing forms sealant B9, the top heat-sealing forms sealant C10, sealant C10 is run through at the electric wire middle part, sealant B9 is run through in the cable bottom, cable 5 upper ends are connected with connector 6, and basement membrane 1 is positioned at sheath 4, in the cavity that forms between sealant A8 and sealant C10, sealant B9, the cavity that forms between sheath 4 and sealant C10 is the sealed vacuum chamber.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
