Description

A kind of Aviation cable

Technical field

The present invention relates to composite cable technical field, more particularly to a kind of Aviation cable.

Background technology

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 cash 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 External diameter is small, in light weight, and occupy little space (series of problems that could be solved with more cables under normal circumstances, can use one herein Root composite rope replaces), the communication cable of data is transmitted, pay much attention to communication quality, and the electromagnetism for coming from outside is done Disturb, it is easy to cause error in data.

But in aerospace field, its anti-shielding ability of existing cable, signal is easily interfered, while also exists The shortcomings that moistureproof refractory ability is poor, tensile strength is weak.

The content of the invention

It is an object of the invention to：In order to solve common photoelectricity meet cable shield effectiveness it is bad, moisture effect is poor asks Topic, the present invention provide a kind of isolation effect good, moistureproof Aviation cable.

The present invention specifically uses following technical scheme to achieve these goals：

A kind of Aviation cable, including a plurality of power line, a plurality of optical fiber cable and a strengthening core, a plurality of power line, a plurality of light Plastic-coated steel belt layer, inner insulating layer, screen layer A, flame retardant coating, damp-proof layer, armor are enclosed with successively outside fine line and a strengthening core And external insulation layer, the gap in plastic-coated steel belt layer are filled with waterproof paste, every power line includes setting gradually from inside to outside There are copper conductor, conductor shield and crosslinked polyetylene insulated layer.

Further, the bar optical fiber cable includes optical fiber cable core, and optical fiber cable core outer wrapping Loose tube.

Further, it is cross-linking radiation polyolefine material that thickness is 0.8~1.6mm that the material of described inner insulating layer, which is, Or cross-linking radiation EP rubbers material.

Further, the flame retardant coating includes copper mesh, expanded granular layer, the mica layer set gradually from inside to outside, institute It is 0.25-0.63mm to state mica layer thickness, and the filament diameter of the copper mesh is 0.26-0.96mm.

Further, screen layer A includes the copper foil layer that thickness is 1.1um, and it is 10um~15um to be coated with thickness on copper foil layer Aluminium foil layer.

Further, screen layer A is the spiral wound screen layer that material is tinned copper wire.

Further, the strengthening core of copper-coated aluminium composite material by being made up.

Beneficial effects of the present invention are as follows：

1st, the present invention is simple in construction, and shield effectiveness is good, and damp-proof and fireproof performance is good, and overall structure is uncomplicated, lighter weight The advantages of, it is beneficial to use suitable for aviation.

2nd, screen layer A includes the copper foil layer that thickness is 1.1um, and the aluminium foil that thickness is 10um~15um is coated with copper foil layer Layer, this structure of screen layer can ensure screen layer under identical thickness, layers of copper used than traditional list using this structure Structure more saving copper material, has saved cost, and on the other hand, aluminium foil quality is lighter, so as to also reduce the weight of screen layer, the knot Structure avoids the problem of occurring exoperidium bulge when working out cable shield using tinsel or pierce through core.

Brief description of the drawings

Fig. 1 is the structural representation of the present invention.
