Description

A kind of depopulated helicopter gondola connection ruggedized cable

Technical field

This utility model is related to electric wire field, and in particular to reinforced electricity is used in a kind of depopulated helicopter gondola connection Cable.

Background technology

With the extensive application of depopulated helicopter, in order to meet the use needs in each field, various functions gondola becomes The necessary equipment of depopulated helicopter.Connection unmanned plane is become increasingly conspicuous with the cable importance of gondola.Existing cable is in weight, anti-song There is certain deficiency in the performances such as, anti-interference, uvioresistant, also insulated wire cores are easily broken core.

Utility model content

In order to overcome the deficiencies in the prior art, there is provided a kind of from heavy and light, the anti-performance that circumnutates be good, interference free performance It is good, the depopulated helicopter gondola connection ruggedized cable of anti-ultraviolet.

For achieving the above object, the utility model discloses a kind of depopulated helicopter gondola connection ruggedized cable, bag Cable core is included, described cable core is combined by trident polyethylene support and six roots of sensation insulated wire cores；Described trident polyethylene Six roots of sensation insulated wire cores are separated by support two-by-two carries out pair twist, and a tin plated steel wire is provided with insulated wire cores；It is outer wrapped in cable core Aluminum-plastic composite membrane lapping layer, extrudes proof copper-wire braided screen layer outside aluminum-plastic composite membrane lapping layer, extrudes anti-purple in cable core outermost layer Outside line polyolefin jacket, is provided with single line convex ridge on uvioresistant polyolefin jacket, and the height of single line convex ridge is not less than 0.5mm, Width is not less than 2mm.

Preferably, described insulated wire cores are by twisted copper conductors and to be extruded in the outer thickness of twisted copper conductors be 0.1mm- The ultra-thin teflon insulation layer of 0.2mm is constituted.

Preferably, three channelizing lines are equidistantly provided with described proof copper-wire braided screen layer.

Preferably, described copper conductor stranded is formed by the ultra-fine copper free wire of a diameter of 0.06mm-0.08mm.

The beneficial effects of the utility model are：

1st, using politef thinwalled insulation, cable weight itself is significantly reduced, mitigates unmanned plane load, increased stagnant Between space-time.

2nd, technique and insulated wire cores special stand are twisted again using ultra-fine copper free wire multilamellar, the relative slip of control conductor reaches The anti-performance that circumnutates of high-quality, significantly extends the service life of cable.

3rd, shielded by aluminum-plastic composite membrane and ultra-fine proof copper-wire braided economic benefits and social benefits, the combinative structure of built-in metal channelizing line to be reaching More preferable interference free performance.

4th, by the feature of environmental protection and uvioresistant work(of whole cable are realized using environment-friendly type uvioresistant polyolefin oversheath Energy.

5th, this utility model has very strong load-carrying properties, and the conductor central layer of cable has a zinc-coated wire, conductor Stress point is concentrated on tin plated steel wire, not easily broken core, is not easily broken.

6th, sheath is provided with single line convex ridge, for the identification of cable, brings very big convenience to maintenance.

Description of the drawings

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

Specific embodiment

Below in conjunction with the accompanying drawings and specific embodiment, further elucidate this utility model, it should be understood that these embodiments are only used for Illustrate this utility model rather than limit scope of the present utility model, after this utility model has been read, art technology Modification of the personnel to the various equivalent form of values of the present utility model falls within the application claims limited range.

As shown in figure 1, this utility model provides a kind of depopulated helicopter gondola connection ruggedized cable, including cable core, Described cable core is combined by trident polyethylene support and six roots of sensation insulated wire cores；Described insulated wire cores are by twisted copper conductors 2 and it is extruded in the outer thickness of twisted copper conductors and constitutes for the ultra-thin teflon insulation layer 3 of 0.1mm-0.2mm；Described three Six roots of sensation insulated wire cores are separated by fork-shaped polyethylene support 1 two-by-two carries out pair twist, and a tin plated steel wire 8 is provided with insulated wire cores； In the outer wrapped aluminum-plastic composite membrane lapping layer 4 of cable core, proof copper-wire braided screen layer 5 is extruded outside aluminum-plastic composite membrane lapping layer, in cable core Outermost layer extrudes uvioresistant polyolefin jacket 6, and single line convex ridge 8 is provided with uvioresistant polyolefin jacket, single line convex ridge Highly it is not less than 0.5mm, width is not less than 2mm.

Further improve, in described proof copper-wire braided screen layer, be equidistantly provided with three channelizing lines 7, reach preferably anti-dry Immunity energy.

Further improve, described copper conductor stranded is formed by the ultra-fine copper free wire of a diameter of 0.06mm-0.08mm.

The above is only preferred implementation of the present utility model, it is noted that for the ordinary skill people of this area For member, on the premise of without departing from this utility model principle, some modifications and improvement can also be made, these also should be regarded as category In protection domain of the present utility model.
