Abstract

The utility model discloses a kind of strong electric wire of crushing resistance, including sheath, some bundle cores are equipped with the sheath, it is trapezoidal often to tie core composition one；It is described often tie that core formed in horizontal direction in sheath it is trapezoidal set to be mutually reverse, often tied in vertical direction in sheath core formed it is trapezoidal consistent；The often bundle core is externally provided with insulation screen, and protective layer is equipped with the outside of insulation screen；Filler is equipped with the gap often tied between core；The utility model often ties the trapezoidal stability for adding its structure of core composition, reaches the effect of pressure resistance.

Description

A kind of strong electric wire of crushing resistance

Technical field

It the utility model is related to a kind of strong electric wire of crushing resistance.

Background technology

Electric wire is transmitting electricity（Magnetic）Can, information and the wire product for realizing electromagnetic energy conversion, the electric wire electricity of broad sense Cable is also referred to simply as cable, and the cable of narrow sense refers to insulated cable, it may be defined as：The aggregate being made of following part；One Or a plurality of insulated core, and the clad that each of which may have, total protective layer and outer jacket, cable can also have additional The conductor not insulated.To transmit electricity（Magnetic）Can, information and the wire product for realizing electromagnetic energy conversion.It is most on the market at present Several electric wires, which exists to be trampled during subsequent use again of constructing still, either to be extruded, so as to cause it to be stepped on Flat or flattening, core that is heavy then may causing the inside are broken, and thus the circuit can be allowed not work normally, together When, during use, also it is easier to roll, needs to improve.

Utility model content

Purpose of utility model：In view of the problems of the existing technology, the utility model provides a kind of stable structure, resistance to compression The strong and wear-resisting electric wire of property.

Technical solution：A kind of strong electric wire of crushing resistance, including sheath, the sheath is interior to be equipped with some bundle cores, often It is trapezoidal to tie core composition one；It is described often tie that core formed in horizontal direction in sheath it is trapezoidal set to be mutually reverse, That often ties that core formed in vertical direction in sheath is trapezoidal consistent；The often bundle core is externally provided with insulation screen, exhausted Protective layer is equipped with the outside of edge shielded layer；Filler is equipped with the gap often tied between core.

Specifically, the filler is asbestos.

Specifically, the sheath is silicon rubber.

Specifically, the core is at least worked out by four groups of copper wires.

Specifically, the angle of the trapezoidal side edges for often tying core composition and broadside is 60 °.

Specifically, the length for often tying the trapezoidal narrow side that core is formed is 1/5th of width edge length.

Beneficial effect：Compared with prior art, the utility model has the advantage of：Often tie the trapezoidal to be upper narrow of core composition Lower width, and 1/5th that the length of narrow side is width edge length, form the structure of class triangle, add the stabilization of its structure Property, reaches the effect of pressure resistance.

Brief description of the drawings

Fig. 1 is the structure diagram of the utility model.

Embodiment

With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate.

As shown in Figure 1, the electric wire that a kind of crushing resistance is strong, including sheath 1, core 2, filler（It is not shown）, insulation Shielded layer 4 and protective layer 5, sheath 1 is interior to be equipped with some bundle cores 2, which is silicon rubber, often ties core 2 and forms a ladder Shape, the length for often tying the trapezoidal narrow side that core 2 is formed is 1/5th of width edge length, and the angle of side and broadside is 60 °； Often tie that core 2 formed in horizontal direction in sheath 1 it is trapezoidal set to be mutually reverse, it is every in vertical direction in sheath 1 Bundle core 2 is formed trapezoidal consistent, and is often equipped with certain interval 3 between bundle core 2, and filler, the filling are equipped with gap 3 Thing is asbestos；The often bundle core 2 is externally provided with insulation screen 4, and protective layer 5 is equipped with the outside of insulation screen 4.

Above-mentioned core 2 is at least worked out by four groups of copper wires.
