Abstract
The utility model discloses a multicore naval ship control cable; a conductor is formed by twisting a plurality of tinned copper wire bundles; the conductor is extruded by a PVC insulating layer; the PVC insulating layer is wrapped by a braided tinned copper wire dividing shielding layer so as to form a wire core; a plurality of wire cores form a cable core wrapped by a polypropylene tape; the polypropylene tape is extruded by an inner sheath wrapped by a braided tinned copper wire armoring layer; no signal interference can be generated between the wire cores, so signal transmission is accurate and reliable; the outer armoring layer can effectively prevent the cable from being affected by outer force.
Description
Technical field
The utility model belongs to electric wire field, is specifically related to a kind of multicore naval vessel control cables.
Background technology
Naval vessel industry is the grand strategy industry of national economy, as the electric wire cable of naval vessel nerve and blood vessel, is directly connected to fail safe, reliability, advance and the fight capability on naval vessel.Along with developing rapidly of China's national defense modernization construction, improve naval vessel power supply, control system safely etc. the measure of aspect will be directly connected to ship survivability.How research improves naval vessel control cables performance, with reduce control cables manufacturing cost, expand the applicable scope of naval vessel control cables, this still can keep ship survivability effective guarantee personnel's safety to have important realistic meaning for naval vessel when the signal disturbed condition.
Utility model content
In order to overcome the deficiency of phase mutual interference between the each heart yearn of existing naval vessel control cables, the utility model provides a kind of multicore naval vessel control cables, and this control cables has not produce between heart yearn and disturbs and carry signal feature and prevent that cable is damaged by exterior mechanical accurately.
Scheme of the present utility model is as follows: a kind of multicore naval vessel control cables, conductor is formed by multiply tin-coated copper wire harness strand, at described conductor, extrude polyvinyl chloride insulation layer outward, vinyl chloride insulation layer weaves tinned wird sub-shield outward) formation core, wrapped polypropylene tape after multiply core stranding, at polypropylene tape skin, extrude one deck inner sheath, inner sheath weaves tinned wird armour outward.
Further, described conductor is formed by 8-20 thigh tin-coated copper wire harness strand.
Further, described multiply core quantity is 10-30.
Further, described multiply core quantity is 19.
Further, described inner sheath is vinyl chloride inner sheath.
The utility model is for transmission of control signals cable, existing control cables is mainly comprised of heart yearn, insulating barrier, screen and sheath, insulating barrier is coated on the outer also many strandings of heart yearn, cable core outer wrapping screen, the effect of screen is to avoid external electromagnetic field on carrying the impact of signal, due to the signal difference that the each heart yearn in cable core is carried, each heart yearn also can cause interference each other, causes the signal of carrying to occur deviation.Owing to taking such scheme, between each heart yearn, can not produce signal and disturb, the transmission number of delivering letters is accurately, reliably.And the impact that outer field armour can effectively stop external force to produce cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 conductor, 2 polyvinyl chloride insulation layers, 3 sub-shields, 4 polypropylene tapes, 5 inner sheaths, 6 armours.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of multicore naval vessel control cables, conductor is formed by multiply tin-coated copper wire harness strand, outside described conductor 1, extrude polyvinyl chloride insulation layer 2,3 layers of formation core of the outer braiding tinned wird of vinyl chloride insulation layer 2 separated-shielding, wrapped polypropylene tape 4 after multiply core stranding, at polypropylene 4, be with skin to extrude one deck inner sheath 5, the outer braiding tinned wird of inner sheath 5 armour 6.
In concrete enforcement, described conductor 1 is formed by 8-20 thigh tin-coated copper wire harness strand; Described multiply core quantity is 10-30, and under entering, described multiply core quantity is 19; Described inner sheath 5 is vinyl chloride inner sheath.
The utility model cable makes by following technical process: the stranded multiply tin-coated copper of accurate stranding machine twisted wire is as conductor 1, at conductor 1 external application normal temperature extrusion equipment, extrude polyvinyl chloride insulation layer 2, braiding machine braiding tinned wird sub-shield 3,19 insulated wire cores are carried out stranding wrapped polypropylene band 4 on cabler, extrude polyvinyl chloride inner sheath layer 5 with normal temperature extrusion equipment, restrictive coating weaves one deck tinned wird armour 6 outward, is final finished cable.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection range of the present utility model.
