Problems solved by technology

[0002] Most of the existing towline cables are multi-stranded structures or single-core structures, both of which have their own shortcomings: because the multi-stranded structures are on different planes, the cables follow the towline When continuously reciprocating in all directions, the force on the conductors on each surface is different. If the cable is used for a long time, the conductor on the frequently stressed surface of the cable is prone to fatigue fracture, which shortens the service life of the cable; Towline cables with a core structure usually lay many cables at one time, sometimes dozens of them. This method is not conducive to the installation of the cables, and it is easy to cause wrong wiring. Moreover, the cables will be kinked and broken after long-term use. question

Embodiment Construction

[0015] A flexible towline cable of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 with figure 2 As shown, a flexible towline cable includes: a plurality of wires with coplanar axes, the same outer diameter and closely arranged side by side, a plurality of ribbon-shaped connectors 9 connected between the wires, each ribbon-shaped connector 9 forms a telescoping cavity between the two wires connected to it, and an adhesive that is arranged to connect the wires in the telescoping cavity; the conductor 8 includes a cable core 1, a non-woven wrapping cloth 5 on the outside of the core, and The sheath 2 outside the non-woven fabric wrapping cloth 5; the wire core includes a tensile wire body 3, four sets of core wires 4 arranged outside the tensile wire body 3, and tensile wires arranged between adjacent core wires 4. Wire body 3; the core wire 4 includes a core wire wire 41 and a core wire insulati...

Abstract

The invention provides a flexible towline cable, which comprises a plurality of wires, which have coplanar axes and the same outer diameter and are closely arranged in parallel, and a plurality of strip-shaped connectors connected between the wires, wherein a telescopic cavity is formed between each strip-shaped connector and two wires in connection therewith; and an adhesive is arranged in the telescopic cavity for connecting each wire; a conductor comprises a cable core, a non-woven wrapping cloth on the outer side of the cable core and a sheath outside the non-woven wrapping cloth. The flexible towline cable in the invention has the advantages of novel structural design, good stability and reliability, long service life and good bending resistance and can effectively solve the problem that the existing towline cable is easily broken; the cable is set in a flat shape; the axes of the wires are on the same plane; the wires with the same outer diameter are closely arranged in parallel,so that the wires of the cable are uniformly stressed in the reciprocal dragging movement and the service life is longer.

Description

technical field [0001] The invention relates to a cable, in particular to a flexible drag chain cable. Background technique [0002] Most of the existing towline cables are multi-stranded structures or single-core structures, both of which have their own shortcomings: because the multi-stranded structures are on different planes, the cables follow the towline When continuously reciprocating in all directions, the force on the conductors on each surface is different. If the cable is used for a long time, the conductor on the frequently stressed surface of the cable is prone to fatigue fracture, which shortens the service life of the cable; Towline cables with a core structure usually lay many cables at one time, sometimes dozens of them. This method is not conducive to the installation of the cables, and it is easy to cause wrong wiring. Moreover, the cables will be kinked and broken after long-term use. question. Contents of the invention [0003] In order to solve the a...
