Description

A kind of multi-functional composite cable

Technical field

The utility model is related to composite cable technical field, more particularly to a kind of multi-functional composite cable.

Background technology

Typically by several or the cable of at least two similar ropes being twisted of several groups of every group of conducting wires, every group of conducting wire it Between mutually insulated, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation.Cable has interior logical Electricity, the feature of external insulation.

Optoelectronic composite cable makees transmission line suitable for broadband access network system, is a kind of new access way, its light harvesting Fine, transmission of electricity copper wire can solve the problems, such as broadband access, equipment electricity consumption, signal transmission in one.

Traditional cable and optical fiber are mostly split, and optoelectronic composite cable structure is less, and scheming logical photoelectric compound cable has Outer diameter is small, light-weight, and occupying little space, (series of problems that could be solved with more cables under normal conditions can use one herein Root composite rope replaces), it the communication cable of data is transmitted, pays much attention to communication quality, and come from external electromagnetism and do It disturbs, it is easy to cause error in data.

Common photoelectric compound cable is simple in structure, and function is single, especially for some to the anti-interference of composite cable Property the higher field of requirement, the shielded layer of common cable mostly worked out using tinsel, and cable shield is susceptible to outer Foreskin bulge or the problem of pierce through core.

How above-mentioned technical problem is solved into the striving direction of those skilled in the art.

Utility model content

The purpose of this utility model is that：In order to solve common photoelectricity meet cable shield effectiveness is bad, dampproof effect is poor The problem of, the utility model provides a kind of isolation effect good, moisture-proof multi-functional composite cable.

The utility model specifically uses following technical scheme to achieve these goals：

A kind of multi-functional composite cable, including control line group, signal line group, speaking wire group, source line group and light unit, control Inner insulating layer, internal shield, aluminium foil are wrapped in successively outside line group processed, signal line group, speaking wire group, source line group and light unit Layer, external shielding layer and external insulation layer are provided with center reinforcemen and screen coaxial line in inner insulating layer.

Further, the material of the inner insulating layer is polybutylene terephthalate (PBT), the gap in inner insulating layer Place is filled with optical fiber cream.

Further, the material of the external insulation layer is the cross-linking radiation polyolefin or irradiation friendship that thickness is 1.5 ~ 2.5mm Join EP rubbers material.

Further, internal shield is along the silver-plated braiding copper mesh layers of the line length direction setting of cable, the silver-plated braiding Copper mesh layers are the silver-plated braiding copper mesh layers that the crisscross silver-gilt copper wire being process by braiding is formed.

Further, external shielding layer includes the copper foil layer that thickness is 1.2um, and the aluminium foil that thickness is 10um is coated on copper foil layer Layer, is provided through the through hole of copper foil layer and aluminium foil layer on shielded layer, and the through hole is into array distribution, pitch of holes 210- 320um, through-hole diameter 21-320um.

Further, the center reinforcemen is worked out by the zinc-coated wire of a diameter of 0.2 ~ 0.3mm.

The beneficial effects of the utility model are as follows：

1st, the utility model is simple in structure, collect control line group, signal line group, speaking wire group, source line group and light unit in The advantages of integral, can realize multiple functions；The setting of internal shield and external shielding layer can realize double layer screen, shielding effect Fruit is good, while the cable overall structure is uncomplicated, has the advantages that lighter weight, is adapted in use to.

2nd, external shielding layer includes the copper foil layer that thickness is 1.2um, and the aluminium foil layer that thickness is 10um, shielding are coated on copper foil layer It is provided through the through hole of copper foil layer and aluminium foil layer on layer, the through hole is into array distribution, pitch of holes 210-320um, through hole A diameter of 21-320um, this structure of shielded layer can ensure shielded layer under identical thickness, using this structure than tradition List copper material is more saved using layers of copper structure, saved cost, on the other hand, aluminium foil quality is lighter, so as to also reduce shielding The weight of layer, shielded layer are evenly equipped with through hole, exoperidium occur when working out cable shield this configuration avoids tinsel is used Bulge or the problem of pierce through core.
