Abstract
A kind of Anti-interference cable is related to Aviation cable field.The Anti-interference cable, insulated wire cores add gas barrier layer outside, can effectively prevent high temperature air, water, oil vapour enter inside cable conductor；Gas barrier layer is set as fan-shaped, the roundness of insulated wire cores is ensure that, the position of insulated wire cores is made to fix, improve the stability of cable.An at least drainage thread is additionally provided between inner sheath and shielded layer, it can be ensured that shielded layer remains excellent interference free performance, meet bonding requirement after laying and in being used for a long time.
Description
Technical field
The utility model is related to Aviation cable field, more particularly to a kind of Anti-interference cable.
Background technology
The electric wire used under the hot environment of aerospace, it is poor to the shield effectiveness of water body and gas, lead to electricity
Cable is easily corroded, and existing method is the thick insulating layer of setting, and this structural volume is big, weight is heavy and is being subjected to outer space high energy electricity
It insulate after son radiation and is easy cracking aging, safety and reliability are poor.
Invention content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of Anti-interference cable, which sets
It counts reasonable, simple in structure, has the advantages that small, shield effectiveness is good.
Technical solution used by the utility model is：A kind of Anti-interference cable, is characterized in that, setting inside cable
There are four insulated wire cores, each insulated wire cores include multiple conductors and fan-shaped insulating layer, and multiple conductors are set in sector
It sets, fan-shaped insulating layer is wrapped in multiple conductors；Gas barrier layer, four insulated wires are further respectively had outside each fan-shaped insulating layer
The outer gas barrier layer of core is in contact, and excircle is rounded；Be enclosed with gas barrier layer insulated wire cores twist together after again outside them
Side is enclosed with inner restrictive coating, shielded layer and external sheath layer successively, and at least one drainage is additionally provided between inner sheath and shielded layer
Line.
In said program, gas barrier layer is sleeve structure.
In said program, the gas barrier layer is polyimides material.
The utility model has the beneficial effects that：The Anti-interference cable, insulated wire cores are added gas barrier layer outside, be can effectively prevent
High temperature air, water, oil vapour enter inside cable conductor；Gas barrier layer is set as fan-shaped, ensure that the roundness of insulated wire cores,
So that the position of insulated wire cores is fixed, improves the stability of cable.At least one drainage is additionally provided between inner sheath and shielded layer
Line, it can be ensured that shielded layer remains excellent interference free performance, meet bonding and want after laying and in being used for a long time
It asks.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without creative efforts, can also be according to these
Attached drawing obtains other attached drawings.
Fig. 1 is the structural schematic diagram of Anti-interference cable in the utility model embodiment；
Number explanation is as follows in figure：1 conductor, 2 insulating layers, 3 gas barrier layers, 4 inner sheaths, 5 shielded layers, 6 oversheaths, 7 drainages
Line, 8 cables.
Specific implementation mode
Keep the above objects, features, and advantages of the utility model more obvious and easy to understand, below in conjunction with the accompanying drawings 1 and specific
Embodiment is described in further detail the utility model.
The Anti-interference cable that the present embodiment kind uses, cable 8 are internally provided with four insulated wire cores, and each insulated wire cores are equal
Including multiple conductors 1 and insulating layer 2, multiple conductors 1 are arranged in fan-shaped, and fan-shaped insulating layer 2 is wrapped in multiple conductors 1,
Gas barrier layer 3 is further respectively had outside each sector insulating layer 2, gas barrier layer 3 is sleeve structure, is extruded into using polyimides material
Type, gas barrier layer 3 plays the role of blocking water, choke.The gas barrier layer 3 of four insulated wire cores 8 is in contact with each other, and excircle is rounded,
The structure can ensure the roundness of cable core 8, and the position of insulated wire cores is made to fix, and improve the stability of cable.It is enclosed with
Four insulated wire cores 8 of gas barrier layer 3 are enclosed with inner restrictive coating 4, shielded layer 5 and outer successively on the outside of them again after twisting together
Restrictive coating 6, wherein shielded layer 5 are made using fluoropolymer, and inner sheath 4 and oversheath 6 are all made of Ceramic silicon rubber
Material can effectively improve the heat resistance of core 8.The present embodiment is additionally provided at least one between inner sheath 4 and shielded layer 5
Drainage thread 7, it can be ensured that shielded layer 5 remains excellent interference free performance, meet shielding and connect after laying and in being used for a long time
Ground requirement.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with the power
Subject to the protection domain that profit requires.
