Above-mentioned flexible heater film goes out in the wire encapsulation construction, and the one side of described dielectric film scribbles adhered layer.
Above-mentioned flexible heater film goes out in the wire encapsulation construction, and the described dielectric film of part extends the back side that is pasted on flexible heater film.
Above-mentioned flexible heater film goes out in the wire encapsulation construction, and described dielectric film comprises one or more described perforates.
Above-mentioned flexible heater film goes out in the wire encapsulation construction, and described perforate is to be positioned at the middle U-shaped perforate that a round hole or an end are positioned at dielectric film central authorities, the other end exposes the dielectric film edge of dielectric film.
Above-mentioned flexible heater film goes out in the wire encapsulation construction, and the insulating barrier of described dielectric film is one or more in polyester film, polyimide film, glass fibre, the polyvinyl fluoride.
The utility model also provides a kind of dielectric film of flexible heater film outlet encapsulation, comprises the perforate that size and cable to be welded mate.
In the dielectric film of above-mentioned flexible heater film outlet encapsulation, described perforate be positioned in the middle of the dielectric film, round hole that diameter and cable mate.
In the dielectric film of above-mentioned flexible heater film outlet encapsulation, described perforate is that an end is positioned at dielectric film central authorities, the other end exposes the U-shaped perforate that dielectric film edge, width and cable diameter are complementary.
Flexible heater film of the present utility model goes out wire encapsulation construction and dielectric film, can effectively protect the connection of flexible heater film outlet, has improved the insulating properties and the sealing of flexible heater film outlet.

Embodiment
As shown in Figure 3, be the schematic diagram of the dielectric film of flexible heater film outlet of the present utility model encapsulation.Two perforates 21 are set in the centre of dielectric film 20.Wherein, dielectric film 20 can be single-layer insulation material, also can be the sandwich construction that comprises insulating barrier, and insulating layer material can be in polyester film, polyimide film, glass fibre, the polyvinyl fluoride one or more.And the diameter of each perforate 21 and be connected the cable size coupling of each end points of resistor disc, it is just seamless to make that cable inserts after this perforate 21.Dielectric film 20 can be located near the bottom margin position in the position of perforate 21, makes the distance of bottom margin of the edge of perforate 21 and dielectric film 20 be not less than the thickness of flexible heater film 10.And the spacing of two perforates 21 is generally in 5 times of diameter of perforate 21, also can be provided with arbitrarily as required.Certainly, the quantity of perforate 21 also is not limited to two, and can be set to 1,3 or more according to the quantity of connection cable.
As shown in Figure 4, be the schematic diagram of another embodiment of the dielectric film of flexible heater film outlet of the present utility model encapsulation.Two U-shaped perforates 21 are set on dielectric film 20.In the present embodiment, U-shaped perforate 21 be arranged in parallel, and with the edge-perpendicular of dielectric film 20, its centre position from dielectric film 20 extends to the edge of dielectric film 20 and forms opening.The width of each perforate 21 and the diameter of cable coupling, it is just seamless to make that cable inserts after this perforate 21.And the spacing of two perforates 21 is generally in 5 times of width of perforate 21, also can be provided with arbitrarily as required.Certainly, two perforates 21 are not limited to the edge-perpendicular with dielectric film 20, and two perforates 21 also are not limited to be arranged in parallel, and the quantity of perforate 21 also is not limited to two, and can be set to 1,3 or more according to the quantity of connection cable.
In another embodiment of the present utility model, an adhered layer also can be established in the back side of dielectric film 10, thereby can make this dielectric film 10 directly to be affixed on the flexible heater film in use, thus hermetically-sealed cable and solder joint.And that the shape of dielectric film 20 also is not limited to is square, can be circular, oval or other shapes, as long as it can cover solder joint.
As shown in Figure 5, flexible heater film of the present utility model goes out the wire encapsulation construction schematic diagram.The perforate 21 that cable 13 inserts on the dielectric film, dielectric film 20 then is attached on the flexible heater film 10, and wraps up solder joint, cable.The part of dielectric film 20 could be adhered to the back side of flexible heater film 10, thereby has improved the insulating properties and the sealing of flexible heater film 10 outlets.When welding, can make cable 13 to be welded insert perforate 21 earlier, then cable 13 is welded on the flexible heater film 10, at last dielectric film 20 is attached to flexible heater film 10 surfaces, and covers solder joint.Because cable 13 is fixed in the perforate 21, in installing and using process, the swing of cable 13 also is limited in the perforate 21, thereby can not make heating film outlet cracking.
