Description

Extendible photoelectricity composite cable

Technical field

The utility model relates to a kind of optical cable, relates in particular to a kind of extendible photoelectricity composite cable, belongs to technical field of electric wires and cables.

Background technology

Extendible photoelectricity composite cable needs on rolling disk or guide wheel, to reel repeatedly, and retractable operation such as under certain operating load, carry out field emergency, mooring, pull is bearing pressure repeatedly, draws, turns round, bends, combined stress such as mill.The characteristics of such cable be to have that softness, tensile strength are big, good stability, mobility strong and good bending property.

The type cable majority in the market is exactly to adopt power cable and signal cable to separate, and has increased the complexity and the working strength of the folding and unfolding of cable like this.Also handlebar power cable and signal cable design in cable recently, but in the utilization process, the problem of existence is that the optical fiber of signal optical cable is easily broken, also runs into the phenomenon that the power core also ruptures once in a while; Also have problems such as sheath cracky, the useful life of cable is shorter, and mechanical performance is relatively poor, can not satisfy user's demand.

Summary of the invention

The utility model is for avoiding above-mentioned existing in prior technology weak point; A kind of extendible photoelectricity composite cable is provided; The characteristics of combined stresses such as it has the pressure of bearing, draw, turn round, bend, mill; Can be under mal-condition, operating state such as be in folding and unfolding, mooring under certain operating load for a long time, pull.

The utility model adopts following technical scheme for the technical solution problem:

The design feature of the utility model extendible photoelectricity composite cable is: cable core is to be coated in the external sheath layer by three power insulated wire cores, ground core and two optical cable core units jointly after stranded; Said power insulated wire cores is to constitute the power line core conductor by thin tinned wird thigh strand of multiply and multiple strand, on said power line core conductor, extrudes polyesters thermoplastic elastomer (TPE) TPE insulating barrier and constitutes the power insulated wire cores; Said ground core is that to be that the center is stranded with aramid fiber silk strand rope form the thin tin-coated copper of multiply; Said optical cable core unit is to fill out core and center part with two secondary coating fibers, two to be star twisting and to set gradually reinforcing element and restrictive coating at the skin of intertwist body; With said ground core is the center, constitutes cable core with three power insulated wire cores and optical cable core unit by the stranded stranding of dextrad, outside said cable core, extrudes the external sheath layer that polyesters thermoplastic elastomer (TPE) TPE forms.

The design feature of the utility model extendible photoelectricity composite cable also is:

Said power line core conductor adopts thin tinned wird thigh strand of the 6th type of multiply and regular multiple stranded conductor structure, and strand twists with to twist direction again identical.

Said ground core is to adopt the 6th type of thin tin-coated copper of multiply, is the structure that tangles of just restoring to norm at center with aramid fiber silk strand rope.

Said optical fiber adopts single model optical fiber.

The external diameter of said optical cable core unit is identical with the external diameter of power insulated wire cores.

Compared with present technology, the utility model beneficial effect is embodied in:

1, insulating barrier has adopted the very high polyesters thermoplastic elastomer (TPE) TPE insulating material of excellent electrical properties, mechanical performance in the utility model; Its material mechanical tensile strength is not less than 16Mpa; Elongation at break is not less than 700%, thereby has absorbed a part of external force, has protected the fail safe of conductor;

2, the utility model external sheath layer adopts polyesters thermoplastic elastomer (TPE) TPE protective cover material, has the advantage of plastics and rubber concurrently, has superior low-temperature pliability, high-wearing feature, good especially toughness, good anti-chemistry and hydrolytic resistance, high-tensile.The variation of simultaneous temperature is very mild to the variation of modulus of elasticity;

3, conductor adopts the 6th type of conductor in the utility model, conductor thigh strand and regular multiple stranded conductor structure, and strand twist with to twist direction again identical, make the cable bending property good, improved the flexibility of cable;

4, in the utility model the ground core be the center structure that tangles of just restoring to norm with aramid fiber silk strand rope, improved cable carrying, the stressed uniformity of tension;

5, optical fiber adopts single mode in the utility model, has improved fiber bandwidth, has increased the stability of transmission range and signal transmission;
