Abstract
The invention provides a flexible cable and belongs to the cable field. The objective of the invention is to solve problems of an existing cable such as poor flexibility. The flexible cable comprises a sheath and at least one line core in the sheath; the flexible cable also comprises a flexible core tube; the flexible core tube is coaxial with the sheath and is located in the sheath; the line cores are arranged between the outer wall of the flexible core tube and the inner wall of the sheath; a flexible filler is arranged between the outer wall of the flexible core tube and the inner wall of the sheath in a filling manner; and the flexible filler coats the line cores. According to the flexible cable of the invention, the coaxial flexible core tube is arranged in the cable, and the flexible filler is arranged between the flexible core tube and the sheath in a filling manner, and therefore, the flexibility of the cable is better.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of flexible cable.
Background technology
Cable is placed in by the conducting wire center of one or more mutually insulated the insulated conductor that sealing sheath forms.Protection cover layer can be added outside it, for transmission, distribute electric energy or transmit the signal of telecommunication.Cable will realize the transmit outer insulation of interior road, and for this reason, wire outside need be provided with the overcoat of multilayer, as insulating barrier, sealant and protective layer.Therefore, cable is general flexible poor, and bending occurs will damage cable.But the cable of some field application needs it to possess certain flexibility, and as robot welding gun field, because the not fixed track of welding gun moves, cable will unavoidably bend.
Summary of the invention
The invention provides a kind of flexible better flexible cable.
For reaching this object, the present invention by the following technical solutions:
The invention provides a kind of flexible cable, comprise sheath and the line heart being no less than being arranged on sheath inside, also comprise flexible core pipe, described flexible core pipe and described sheath coaxially arrange and are positioned at sheath inside, the described line heart is arranged between flexible core tube wall and jacket inner wall, flexible filler is filled with, the coated described line heart of described flexible filler between flexible core tube wall and jacket inner wall.
Further technical scheme is, described line heart circumferential array centered by the axis of flexible core pipe is arranged.
Further technical scheme is, the described line heart arranged outside of circumferential array has band, and described band outer wall and described jacket inner wall glue together fixing.
Further technical scheme is, the described line heart is that the coated anti-elater core cylindrical of some copper cash becomes, and is coated with insulating barrier outside each described line heart.
Further technical scheme is, described flexible filler is cotton thread.
Further technical scheme is, described flexible core pipe is that polypropylene PP manages.
Further technical scheme is, described sheath is rubber tube.
Beneficial effect of the present invention is:
Establish coaxial flexible core pipe in the present invention in the cable and between flexible core pipe and sleeve pipe filling flexible filler, the flexibility of cable is better.
Accompanying drawing explanation
The structural representation of the flexible cable that Fig. 1 provides for the preferred embodiment of the present invention.
In figure:
1, sheath; 2, the line heart; 3, flexible core pipe; 4, flexible filler; 5, band; 21, copper cash; 22, anti-elater stem stem.
Embodiment
Technical scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
Preferred embodiment
Present embodiments provide a kind of flexible cable, as shown in Figure 1, this flexible cable comprises sheath 1 and is arranged on the line heart 2 being no less than of sheath 1 inside, also comprise flexible core pipe 3, flexible core pipe 3 arranges with sheath 1 is coaxial and is positioned at sheath 1 inside, the line heart 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, the flexible filler 4 covering thread heart 2.
The line heart 2 is formed for the coated anti-elater stem stem 22 of some copper cash 21, is coated with insulating barrier outside each line heart 2.Anti-elater is made primarily of polyaryl fiber, has that hot strength is high, wettability is high, dimensionally stable, an advantage such as heat-resisting and wear-resisting, for filling the splicing thread heart 2.
The line heart 2 circumferential array centered by flexible core pipe 3 axis is arranged.The line heart 2 arranged outside of circumferential array has band 5, and band 5 outer wall and sheath 1 inwall glue together fixing.The line heart 2 can be a wire (as above-mentioned) also can be one group of wire, often organizes wire and comprises 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 uses rubs by cotton fiber spin elongated with the hands and can the cotton thread of complications arbitrarily, the advantages 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 to bend, have certain flexibility.Preferred in the present embodiment, flexible core pipe 3 is managed for polypropylene PP; Sheath 1 is rubber tube.
The present embodiment in cable, establish coaxial flexible core pipe 3 and between flexible core pipe 3 and sleeve pipe filling flexible filler 4, the flexibility of cable is better.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present invention, and these modes all will fall within protection scope of the present invention.
