This flexible cable includes the sheath and sets up at the inside sinle silk of being no less than one of sheath, still contains flexible core pipe, flexible core pipe with the coaxial setting of sheath and be located the sheath inside, the sinle silk setting is between flexible core outside of tubes wall and sheath inner wall, the packing has flexible filler, flexible filler cladding sinle silk between flexible core outside of tubes wall and the sheath inner wall. This application is established coaxial flexible core pipe and fill flexible filler between flexible core pipe and sleeve pipe in the cable, the flexibility of cable is better.

Description

A kind of flexible cable

Technical field

This utility model relates to field of cables, particularly relates to a kind of flexible cable.

Background technology

Cable is to be placed in, by the conductor wire core of one or more mutually insulated, the insulated conductor constituted in sealing sheath. Protection cover layer can be added outside it, be used for transmitting, distributing electric energy or transmit the signal of telecommunication. Cable to realize interior road transmission exterior insulation, for this, need to be provided with the overcoat of multilamellar outside wire, such as insulating barrier, sealant and protective layer. Therefore, cable is generally flexible poor, occurs bending will damage cable. But, the cable of some field application needs it to possess certain flexibility, and such as robotic gun field, owing to the not fixed track of welding gun moves, cable will unavoidably bend.

Utility model content

This utility model provides a kind of flexible better flexible cable.

For reaching this purpose, this utility model by the following technical solutions:

This utility model provides a kind of flexible cable, including sheath and be arranged on the core no less than within sheath, also comprise flexible core pipe, described flexible core pipe and described sheath are coaxially disposed and are positioned at inside sheath, described core is arranged between flexible core tube wall and jacket inner wall, being filled with flexible filler between flexible core tube wall and jacket inner wall, described flexible filler is coated with described core.

Further technical scheme is, described core circumferential array centered by the axis of flexible core pipe is arranged.

Further technical scheme is, the described core arranged outside of circumferential array has band, and described band outer wall and described jacket inner wall gluing are fixed.

Further technical scheme is, described core is that some copper cash are coated with anti-elater core cylindrical one-tenth, is coated with insulating barrier outside each described core.

Further technical scheme is, described flexible filler is cotton thread.

Further technical scheme is, described flexible core pipe is polypropylene PP pipe.

Further technical scheme is, described sheath is rubber tube.

The beneficial effects of the utility model are:

This utility model in the cable in set coaxial flexible core pipe and between flexible core pipe and sleeve pipe filling flexible implant, cable flexible better.

Accompanying drawing explanation

The structural representation of the flexible cable that Fig. 1 provides for this utility model preferred embodiment.

In figure:

1, sheath; 2, core; 3, flexible core pipe; 4, flexible filler; 5, band; 21, copper cash; 22, anti-elater stem stem.

Detailed description of the invention

The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention.

Preferred embodiment

Present embodiments provide a kind of flexible cable, as shown in Figure 1, this flexible cable includes sheath 1 and is arranged on the core 2 no less than within sheath 1, also comprise flexible core pipe 3, flexible core pipe 3 and sheath 1 are coaxially disposed and are positioned at sheath 1 inside, core 2 is arranged between flexible core pipe 3 outer wall and sheath 1 inwall, is filled with flexible filler 4 between flexible core pipe 3 outer wall and sheath 1 inwall, and flexible filler 4 is coated with core 2.

Core 2 is coated with anti-elater stem stem 22 for some copper cash 21 and is formed, and is coated with insulating barrier outside each core 2. Anti-elater is mainly made up of polyaryl fiber, has hot strength height, wettability height, dimensionally stable, the advantage such as heat-resisting and wear-resisting, is used for filling enhancing core 2.

Core 2 circumferential array centered by flexible core pipe 3 axis is arranged. Core 2 arranged outside of circumferential array has band 5, and band 5 outer wall and sheath 1 inwall gluing are fixed. Core 2 can be a wire (as above-mentioned) can also be one group of wire, and often group wire includes multiple conducting wires, i.e. circumferential array many groups wire between flexible core pipe 3 outer wall and sheath 1 inwall. Preferably, flexible filler 4 use by cotton fiber rub with the hands spin elongated and can the cotton thread of any complications, the advantage such as cotton thread has that cost is low, moisture absorption and softness.

The concrete material of flexible core pipe 3 and sheath 4 is not limit, as long as can bending, having certain flexibility. In the present embodiment preferably, flexible core pipe 3 is that polypropylene PP manages; Sheath 1 is rubber tube.

The present embodiment set in cable coaxial flexible core pipe 3 and between flexible core pipe 3 and sleeve pipe filling flexible implant 4, cable flexible better.

Know-why of the present utility model is described above in association with specific embodiment. These describe and are intended merely to explanation principle of the present utility model, and can not be construed to the restriction to this utility model protection domain by any way. Based on explanation herein, those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes fall within protection domain of the present utility model.
