Description

A kind of cable

Technical field

This utility model belongs to technical field of electric wires and cables, especially relates to a kind of cable.

Background technology

The existing construction of cable includes many conductors, is coated on the insulating barrier outside each conductor, braid and four parts of restrictive coating, wherein, conductor constitutes insulated wire cores with insulating barrier, and braid is wrapped in the outside of many insulated wire cores, and restrictive coating is coated on the outer surface of braid.In building site, factory, under the working environment such as mining site, cable can run into curling, pull, mobile, hang the situations such as wiring, cable is in stress for a long time, and cable jacket be may result in traditional cable jacket cracking failure by force phenomenon frequently, reduces service life.But conductive core is embedded in insulating body, conductive core easily produces relative motion at insulating body, and conductive core is easily with respect to displacement, poor structural reliability；And existing cable typically uses the polrvinyl chloride with flame retardant effect as protective layer and insulating barrier, and pvc material is the most aging, and resistance to elevated temperatures is poor；Therefore improved.

Summary of the invention

The purpose of this utility model is the deficiency existed for above-mentioned prior art, it is provided that a kind of cable, and it has, and tensile strength is big, invulnerability is strong, structural reliability is high, high stability, heat-resisting quantity and the feature of rub resistance.

In order to realize above-mentioned purpose, this utility model be the technical scheme is that a kind of cable, including cable core, packed layer and external sheath layer；Described packed layer is wrapped in outside cable core, and described external sheath layer is wrapped in outside packed layer；Described cable also includes spy's many dragons core；Described spy many dragons core includes that Teduolong wire and insulating barrier, described insulating barrier are wrapped in outside Teduolong wire；Described cable core includes metallic conductor and metal dielectric layer；Described metal dielectric layer is wrapped in outside metallic conductor；Male-female engagement spline structure it is provided with between described metal dielectric layer and packed layer；Described external sheath layer is made up of polyvinyl chloride layer and layer of polyester fiber from inside to outside.

It is provided with screen layer between described packed layer and external sheath layer.

The outer surface of described external sheath layer is provided with corrosion-resistant coating.

After using said structure, compared to the prior art this utility model has the advantage, that this utility model simple in construction, by the setting of spy's many dragons core, can improve tensile strength and the invulnerability of cable, the most not affect the pliability of cable, durable in use；Being provided with male-female engagement spline structure between insulating barrier and packed layer so that cable core is difficult to relative displacement, structural reliability is high；External sheath layer uses polyvinyl chloride layer and layer of polyester fiber to constitute, and polyester fiber has, and intensity is high, high temperature resistant, toughness is high, the performance of rub resistance so that cable has more preferable stability, heat-resisting quantity and rub resistance.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

The following stated is only preferred embodiment of the present utility model, the most therefore limits protection domain of the present utility model, further illustrates this utility model with embodiment below in conjunction with the accompanying drawings.

Embodiment, as shown in Figure 1, a kind of cable, including cable core 10, packed layer 11 and external sheath layer；Packed layer 11 is wrapped in outside cable core 10, and external sheath layer is wrapped in outside packed layer 11；The material of packed layer 11 can be gasket for packing, such as PP rope etc..Screen layer 20 it is provided with so that there is good shielding properties and anti-tampering effect between packed layer 11 and external sheath layer.Cable also includes spy's many dragons core 12, and special many dragon cores 12 include Teduolong wire 13 and insulating barrier 14, and insulating barrier 14 is wrapped in outside Teduolong wire 13, and the material of insulating barrier 14 can select PVC, PE, XLPE, polypropylene PP, fluoroplastics F, rubber etc.；By the setting of spy's many dragons core 12, tensile strength and the invulnerability of cable can be improved, the most do not affect the pliability of cable, durable in use, increase the service life.Cable core 10 includes metallic conductor 15 and metal dielectric layer 16, and metal dielectric layer 16 is wrapped in outside metallic conductor 15, and the material of metallic conductor 15 can select copper, aluminum, alloy etc., metal dielectric layer 16 is wrapped in the outside of metallic conductor 15, is combined into metallic conductor core, the material of metal dielectric layer 16 can select PVC, PE, XLPE, polypropylene PP, fluoroplastics F, rubber etc..Being provided with male-female engagement spline structure 17 between metal dielectric layer 16 and packed layer 11 so that cable core 10 is difficult to relative displacement, structural reliability is high.External sheath layer is made up of polyvinyl chloride layer 18 and layer of polyester fiber 19 from inside to outside, and polyester fiber has, and intensity is high, high temperature resistant, toughness is high, the performance of rub resistance so that cable has more preferable stability, heat-resisting quantity and rub resistance.The outer surface of external sheath layer is provided with corrosion-resistant coating 21 so that cable can not corroded, and increases the service life.

Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this utility model, although this utility model being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
