Description

A kind of electric wire

Technical field

This application involves electric wire field more particularly to a kind of electric wires.

Background technique

Electric wire is usually the connecting line being applied to inside commercial electronic, electric appliance and equipment and instrument.Existing electric wire is logical It is often to be made of wire core and insulating bag covering layer, but since electronic equipment is because of prolonged work, amount of heat can be generated, Mechanical wiring inside equipment and the electric wire of surrounding are also in for a long time simultaneously in the environment of high temperature, and insulation is easily caused to be wrapped up Layer softening, or even be burned.

Utility model content

This application provides a kind of electric wires, to solve that big calorimetric can be generated since electronic equipment is because of prolonged work It measures, the electric wire of mechanical wiring and surrounding inside equipment is also in for a long time simultaneously in the environment of high temperature, easily causes to insulate Wrapping layer softening, or even the problem of be burned.

The application provides a kind of electric wire, including core main body, and the core body outer surface from the inside to the outside according to Insulating layer, thermal insulation layer, flame-retardant layer and the tensile layer of secondary setting；

Insulation hole is equipped with inside the thermal insulation layer；

The core main body includes a center-filled core wire and three conductors；

Three conductor loops are arranged around center-filled core wire, and the outer surface of three conductors is tangent two-by-two；

The outer surface of the center-filled core wire is tangent with the outer surface of three conductors respectively.

Further, the center-filled core wire is Kevlar core wire, and the Kevlar core wire is by more Kevlar tow It closes.

Further, wearing layer 7 is enclosed on the tensile layer.

Further, the flame-retardant layer is made of the polyolefine material of low-smoke non-halogen flame-retardant.

Further, the outside of the wearing layer is additionally provided with sheath.

From the above technical scheme, it this application provides a kind of electric wire, is thermally shielded using thermal insulation layer, and in order to Heat dissipation radiates in the insulation hole of thermal insulation layer setting, reduces the temperature of electric wire, while it is resistance to using flame-retardant layer to increase electric wire The fire-retardant intensity of fire, the case where preventing insulating layer from causing to soften due to high temperature, or even burn.

Detailed description of the invention

In order to illustrate more clearly of the technical solution of the application, letter will be made to attached drawing needed in the embodiment below Singly introduce, it should be apparent that, for those of ordinary skills, without any creative labor, It is also possible to obtain other drawings based on these drawings.

Fig. 1 is a kind of structural schematic diagram of electric wire provided by the present application.

Wherein, 1- conductor, 2- center-filled core wire, 3- insulating layer, 4- thermal insulation layer, 5- flame-retardant layer, 6- tensile layer, 7- are wear-resisting Layer, 8- insulation hole.

Specific embodiment

Referring to Fig. 1, the application provides a kind of electric wire, including core main body, and the core body outer surface by It is interior to the insulating layer 3 set gradually outside, thermal insulation layer 4, flame-retardant layer 5 and tensile layer 6, it is preferable that OK a karaoke club layer be nylon tensile layer 6,

Insulation hole 8 is equipped with inside the thermal insulation layer 4；

The core main body includes a center-filled core wire 2 and three conductors 1；Optionally, conductor 1 is copper wire；

Three conductors 1 are arranged around center-filled core wire 2, and the outer surface of three conductors 1 is tangent two-by-two, and three A conductor 1 is tangent two-by-two, can increase the anti-pressure ability and tensile capacity of electric wire；

The outer surface of the center-filled core wire 2 is tangent with the outer surface of three conductors 1 respectively.

From the above technical scheme, it this application provides a kind of electric wire, is thermally shielded using thermal insulation layer 4, and is Heat dissipation radiates in insulation hole 8 that thermal insulation layer 4 is arranged, reduces the temperature of electric wire, while increasing electricity using flame-retardant layer 5 The intensity of sub-line fire resistant flame retardant prevents insulating layer 3 from causing to soften due to high temperature, or even the case where burn.

Further, the center-filled core wire 2 is Kevlar core wire, and the Kevlar core wire is by more Kevlar tow It closes.Kevlar core wire has the advantages that tensile property is good, intensity is high, can increase the tensile capacity of electric wire.

Further, wearing layer 7 is enclosed on the tensile layer 6.

Further, the flame-retardant layer 5 is made of the polyolefine material of low-smoke non-halogen flame-retardant.

Further, the outside of the wearing layer 7 is additionally provided with sheath.
