Wherein: sheath 10, accommodation space 12, cable 14, jacket 15, conductor 16, insulation layer 18, first strap 20, wrapping layer 22, filler 24, air tube 26, second strap 28, and partition 30.

Detailed Description

The technical scheme of the patent is further described in detail below with reference to the specific embodiments.

Embodiment one: as shown in fig. 1 and 2, the assembled drag chain cable of the present utility model includes a sheath 10 and a cable 14 which is detachable and movable in the sheath 10, the sheath 10 can move back and forth and can bend and form a steering arc between two ends in the length direction, the sheath 10 can be provided with one or more accommodating spaces 12 along the length direction, the outer layer of the cable 14 is wound with an outer cover 15 made of PTFE film material, the cable 14 includes a plurality of conductors 16 wound with an insulating layer 22, the space between the conductors 16 and the outer cover 15 is also provided with a filler 24 made of cotton thread from inside to outside in the first tape 20 and the winding layer 22, and the space between the conductors 16 and the first tape 20 can be one wire or a plurality of wires.

Embodiment two: as shown in fig. 3, the difference from the first embodiment is that the air pipe 26 made of TPU is further included, a second wrapping band 28 is wound on the outer peripheral wall of the air pipe 26, the second wrapping band is made of PTFE film, and the air pipe 28 is also inserted into the accommodating space 12 of the sheath 10.

Embodiment III: as shown in fig. 4, the difference from the first embodiment is that the adjacent accommodating spaces 12 are all communicated, a partition portion 30 is provided between two adjacent accommodating spaces 12, and the surface of the partition portion 30 abutting against the accommodating space 12 is an arc surface.

In the first embodiment, the outer cover 15 uses the PTFE film as the insulating layer, and is wound obliquely according to the front and back three layers, so that the outer protective layer of the conventional cable 14 is omitted, the diameter of the cable 14 is reduced, the aperture and the specification of the sheath 10 are manufactured according to the specification of the cable 14, so that the sheath 10 and the cable 14 are more adaptive, meanwhile, compared with the conventional sheath 10, the aperture and the specification of the sheath 10 manufactured by the method are also reduced, the bending radius is smaller, the height in the operation process is reduced, the space utilization is improved, the method is suitable for more occasions, especially places with smaller space, and then the cable 14 passes through the accommodating space 12 of the sheath 10, and the PTFE film material is wound to play the roles of tensile protection and lubrication, so that the penetration of the cable 14 is easier.
