Abstract

A tensile-resistance abrasion-resistance mobile control cable is characterized in that a conductor is formed by intertwisting a plurality of bare flexible copper wires or tinned flexible copper wires; an insulated layer made of wrapped rubber-plastic alloy on the conductor forms an insulated core; every three to seven insulated cores surround a fiber cable-laid rope to be intertwisted into a unit cable core in the left direction; thin and non-woven cloth bands are overlapped on the unit cable core to form a unit group; seven unit groups are intertwisted into a cable in the left direction according to a structure of one plus six to form an integrated cable core; an inner lining formed by wrapping and a strengthening layer weaved by fiber yarns are installed at the outer surface of the integrated cable core; and an outer restrictive coating is wrapped at the outer surface of the strengthening layer. The cable has double functions of signal control and electric energy transmission, and has the advantages of inflaming retarding, resistance to bending, strong tensile resistance, abrasion resistance, flexibility, mechanical shock resistance, long service life, and the like.

Description

The tension wear-resisting type moves control cable

Technical field

The utility model relates to a kind of electrical equipment cable, relates in particular to a kind of tension wear-resisting type and moves control cable, belongs to technical field of electric wires and cables.

Background technology

Because the particularity of its environment, its electrical equipment all needs certain specific (special) requirements with cable.For mobile class cable, not only to satisfy the electric property requirement, and need performances such as tension, resistance to wear, anti-extraneous mechanical impact force and softness sometimes.

Chinese patent 200820063959.X has adopted steel wire as tensile elements, but needs the high flexibility removal cable just undesirable.

Chinese patent 200520072377.4 adopts on the conductors and adds the steel wire reinforcing element, adopts the metal wire knitted reinforcing element between inner covering and the oversheath, has also that cable is heavy, flexibility is poor, a shortcoming such as anti-bending not.

Chinese patent 200620073107.X reinforcing element is stranded with conductor in ground wire, mainly is the communication class cable that is applied to use in the electric component.

Tensile type cable tension original paper mainly is wire and cordage etc. at present, and majority is placed in the middle of conductor or the sheath, and the core arrangement architecture of cable does not have much variations basically.This class cable all exists some problems or deficiency in manufacturing and use, be necessary to be improved in design with in making.

Summary of the invention

The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of tension wear-resisting type to move control cable, have the dual-use function of signal controlling and electric energy transmitting, and have advantages such as fire-retardant, anti-bending, strong, wear-resisting, soft, the anti-mechanical shock of anti-drag force and long-life.

The utility model technical solution problem adopts following technical scheme:

The design feature that the utility model tension wear-resisting type moves control cable is that conductor adopts many soft bare copper wires or zinc-plated soft copper skein silk to close to form, the insulating barrier that extrudes the rubber and plastic alloy material on described conductor constitutes insulated wire cores, per 3～7 thoroughly do away with the edge core is twisted into the unit cable core around the fiber strand rope by left-hand, overlapping wrapped thin nonwoven fabric belts constitutes the unit group on the unit cable core, seven unit groups are pressed the stranded stranding of left-hand by " 1+6 " structure, constitute comprehensive cable core, set gradually the inner covering that extrudes formation and the reinforced layer of filament braiding at the outer surface of described comprehensive cable core, be extruded with external sheath layer in the appearance of reinforced layer.

The design feature that the utility model tension wear-resisting type moves control cable also is:

Described conductor adopts the 5th class conductor or the 6th class conductor structure.

The stranded lay ratio of described unit cable core insulated wire cores is 14-16, and the stranded lay ratio of described comprehensive cable core unit group is 20-25.

Described inner covering and external sheath layer adopt thermoplastic polyester composite elastic body material to extrude formation.

The reinforced layer count of described filament braiding is 40-60%.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, in the utility model insulated wire cores subdivision group, and constitute comprehensive cable core by seven unit groups, the element that the carrying pulling force is arranged respectively in every unit group on the one hand, make whole cable stressed evenly, reduce stress concentration point, improved the useful life of cable, this structure has optimum stabilization and flexibility on the other hand;

2, insulating barrier has adopted the very high rubber and plastic alloy material of excellent electrical properties, mechanical performance in the utility model, its material mechanical tensile strength is not less than 30Mpa, elongation at break is not less than 250%, thereby has absorbed a part of external force, has protected the fail safe of conductor;

3, the reinforced layer of fiber strand rope and filament braiding in the utility model as the element of carrying external broach, plays the purpose of protection cable;

4, conductor adopts the 5th class conductor or the 6th class conductor in the utility model, makes the cable bending property good, has improved the flexibility of cable.

5, the utility model inner covering and external sheath layer adopt thermoplastic polyester composite elastic body material to extrude formation, and its material has high mechanical properties, high flexibility, satisfies the needs of tension external force, mechanical pressure and mobile occasion.
