Abstract

The invention relates to the technical field of cables, in particular to a cable easy to bend. The cable easy to bend comprises a cable body, the cable body comprises a plurality of conductor wire materials, an insulating layer, a steel wire braiding layer and a protecting layer sequentially from inside to outside, a plurality of glue lines are contained between every two conductor wire materials, the diameter of the glue lines is far less than that of the conductor wire materials, and the conductor wire materials and the glue lines are wrapped in the insulating layer. When the cable is used, the conductor wire materials press the glue lines, and the conductor wire materials are buffered when the conductor wire materials are bent, so that friction among the conductor wire materials is reduced, and wear and broken line phenomena caused by the friction are avoided. The cable easy to bend has the advantages of being simple in structure, reasonable in arrangement, low in production cost and the like.

Description

A kind of flexible cable

Technical field

The present invention relates to a kind of cable technical field, particularly a kind of flexible cable.

Background technology

In the every field that cable is widely used in producing, living, some cables will be accompanied by mechanical device and do round bending motion; In such bending motion process, between the heart yearn of cable inside, will produce friction, so long-term bending motion can cause heart yearn wearing and tearing broken string.For fear of this phenomenon, a lot of producers all improve from the material aspect of cable, have used some expensive wire rods and outer layer insulation skin, have so just extended the useful life of cable; But this cable cost is higher, can not be used widely.Therefore, how to provide the problem such as cable of a kind of long service life, low cost to become the focus of research in the industry.

Summary of the invention

The object of the invention is to defect and deficiency for prior art, a kind of flexible cable simple in structure, reasonable in design, easy to use is provided.

For achieving the above object, the technical solution used in the present invention is:

The flexible cable of one of the present invention; comprise line body; described line body is from interior some strip conductor wire rods, insulating barrier, steel wire braid and the protective layer of containing successively outward; between every two strip conductor wire rods, contain and accompany some tree laces; the diameter of described tree lace is far smaller than the diameter of conductor wires, and described some strip conductor wire rods and described some tree laces are insulated layer and are wrapped in.

Further, between described insulating barrier and described steel wire braid, be provided with screen, described screen is netted copper litz wire.

Further, the little wire of multiply is contained in described conductor wires inside.

Adopt after said structure, beneficial effect of the present invention is: the flexible cable of one of the present invention, comprise line body, described line body contains some strip conductor wire rods outward successively from interior, insulating barrier, steel wire braid and protective layer, between every two strip conductor wire rods, contain and accompany some tree laces, the diameter of described tree lace is far smaller than the diameter of conductor wires, described some strip conductor wire rods and described some tree laces are insulated layer and are wrapped in, use time of the present invention, oppress tree lace by conductor wires, can make conductor wires be cushioned in the time of bending, thereby the friction between minimizing conductor wires, avoid the wearing and tearing and the broken string phenomenon that therefore cause.The advantages such as the present invention has simple in structure, arranges rationally, and cost of manufacture is low.

6, steel wire braid; 7, protective layer.

Embodiment

Below in conjunction with accompanying drawing, the present invention is further illustrated.

As shown in Figure 1; the flexible cable of one of the present invention; comprise line body 1; described line body 1 is from interior some strip conductor wire rods 2, insulating barrier 4, steel wire braid 6 and the protective layer 7 of containing successively outward; between every two strip conductor wire rods 2, contain and accompany some tree laces 3; the diameter of described tree lace 3 is far smaller than the diameter of conductor wires 2, and described some strip conductor wire rods 2 and described some tree laces 3 are insulated layer 4 and are wrapped in.Like this, in the time that conductor wires is bending, conductor wires 2 can be cushioned by compressing tree lace 3, thereby avoids the friction between conductor wires 2, the wearing and tearing of stopping therefore to cause or broken string phenomenon.In addition, conductor wires 2 can be coated some oil or talcum powder with tree lace 3, to reduce the frictional force between conductor wires 2 and tree lace 3, extends the useful life of conductor wires 2.

As the novel a kind of optimal way of this reality, between described insulating barrier 4 and described steel wire braid 6, be provided with screen 5, described screen 5 is netted copper litz wire, to be applicable to the application of different places.

As the novel a kind of optimal way of this reality, the little wire of multiply is contained in described conductor wires 2 inside, and the little wire of multiply also can be coated some oil or talcum powder, to reduce the frictional force between the little wire of multiply, extends the useful life of little wire.

In the time that use is of the present invention, not only can avoid conductor wires wear and rupture in the time of frequent bending, the useful life of extended line body; And be not subject to the signal limitations in place, easy to utilize.In addition, this is simple in structure, reasonable in design, low cost of manufacture.

The above is only preferred embodiments of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
