The design has the ground plane, and the security can be improved to in use ground plane ground connection, avoids the potential safety hazard of leaking electricity and causing, simultaneously, the ground plane also can play the shielded effect, shields electromagnetic radiation.

Description

A kind of line with heating function

Technical field

This utility model relates to technical field of electric wires and cables, specifically a kind of line with heating function.

Background technology

In the winter time, all warm oneself with floor heating in family or public market etc., and its warm source is to give off from underground Come the interior space and reach the effect of heating.Electricity floor heating is to heat by being laid on the heating of underground heating cable Ground.Heating cable in floor heating at present mainly uses the cable that metal exothermic material is made, this heating electric The quality of cable is harder, can be destroyed such as repeatedly bending in work progress, here it is require at work progress Middle builder's extreme care, it is to avoid repeatedly bending cable.Owing to the civilian electricity of China is the alternating current of 50HZ, Therefore, can produce the electromagnetic wave field of a mechanical periodicity when using this heating cable, user then can be long-term Being in such a electromagnetic wave field, human body is produced many harmful effects, the most existing heating cable needs To set up screen layer in inside, not only to cause the construction of cable complex, and production and processing cost is the highest.

Carbon fiber is the new material of a kind of excellent in mechanical performance, and its proportion is less than the 1/4 of steel, and tensile strength is but Being 7-9 times of steel, tensile modulus of elasticity is also higher than steel.The specific heat of carbon fiber and electric conductivity are between nonmetal and golden Between genus, carbon fiber has the incomparable many superiority of the electric heating element such as metal, PTC as electric heating element Energy.Make the heat generating wire cable of all size with carbon fiber, there is carbon and the two-fold advantage of fiber and characteristic, Compare all to account for metallic cable at aspects such as safety, energy-conservation, comfortablenesses and have great advantage, be tradition floor heating The optimal substitute products of cable.

But existing carbon fiber heating cable simple in construction, if there is drain conditions, can cause the person Damage greatly, safety can not meet demand.

Utility model content

The utility model proposes a kind of line with heating function, solve asking of carbon fiber cable poor stability in prior art Topic.

The technical solution of the utility model is achieved in that

A kind of line with heating function, including inner wire be wrapped in the restrictive coating outside inner wire；Described inner wire includes Carbon fiber exothermic part, described carbon fiber exothermic part outer wrap insulating barrier, and described insulating barrier outer wrap Ground plane for ground connection.

Further, described ground plane is braiding copper mesh.

Further, described insulating barrier is cross-linked polyethylene layer.

Further, described restrictive coating is low smoke and zero halogen restrictive coating or polyester restrictive coating.

Further, described inner wire includes that sealing coat, described sealing coat are positioned at described insulating barrier and described connect Between stratum.

Further, described sealing coat is low smoke and zero halogen sealing coat or polyester sealing coat.

Further, the quantity of described inner wire is one.

Further, the quantity of described inner wire is two.

Further, two described inner wire pair twists in the shape of a spiral are inside described restrictive coating.

The beneficial effects of the utility model are:

The design of this utility model structure is simple, easy to use；Being designed with ground plane, in use ground plane connects Ground, can improve safety, it is to avoid the potential safety hazard that electric leakage causes；Meanwhile, ground plane can also play screen The effect covered, masks electromagnetic radiation.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by right In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that below, Accompanying drawing in description is only embodiments more of the present utility model, for those of ordinary skill in the art, On the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model The scope of protection.

Embodiment 1

As it is shown in figure 1, the line with heating function in the present embodiment, including inner wire 1 with to be wrapped in inner wire 1 outside Restrictive coating 2；Described inner wire 1 includes carbon fiber exothermic part 3, described carbon fiber exothermic part 3 outer wrap Insulating barrier 4, described insulating barrier 4 outer wrap sealing coat 5, and described sealing coat 5 outer wrap and is used for The ground plane 6 of ground connection.

In the present embodiment, described ground plane 6 is braiding copper mesh；Described sealing coat 5 is low smoke and zero halogen sealing coat, Actual application can also be polyester sealing coat；Described insulating barrier 4 is cross-linked polyethylene layer；Described restrictive coating 2 For low smoke and zero halogen restrictive coating, it is also possible to for polyester restrictive coating.Here inner wire 1 quantity is one.

In the present embodiment, cross-linked polyethylene layer is possible not only to insulation, it is also possible to be effectively improved the high temperature resistant of cable Grade.Ground plane 6 in use ground connection, can improve safety, it is to avoid the potential safety hazard that electric leakage causes； Meanwhile, ground plane 6 can also play the effect of shielding, masks electromagnetic radiation.Restrictive coating 2 protects inside Line 1, uses low smoke and zero halogen material, environment-protecting asepsis evil.

Embodiment 2

As Figure 2-3, the line with heating function in the present embodiment, its structure is substantially the same manner as Example 1, distinguishes In: in the present embodiment, the quantity of described inner wire 1 is two, and two described inner wire 1 are the most right Twist in described restrictive coating 2 internal.

Carbon fiber exothermic part 3 pair twist structure in the shape of a spiral, can make line with heating function from becoming loop, carbon fiber exothermic part 3 The electromagnetic radiation produced cancels each other out, and effectively overcomes electromagnetic radiation.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.
