Description

High-efficient cable of easy wiring

Technical Field

The utility model relates to a cable especially relates to a high-efficient cable of easy wiring.

Background

In some electrical devices, the cable needs to be frequently bent and fixed during internal wiring. At present, a common cable has certain elasticity, so that the common cable is difficult to rebound after being bent and wired, the common cable cannot be well fixed, the common cable is easy to disorder and the appearance is also influenced. At present, most of the solutions are to use a cable tie to tie the cables, but the method not only causes the disorder of wiring and influences the appearance, but also causes the difficulty in heat dissipation when the wires are tied together, reduces the load which can be passed by the cables and influences the service life of the cables.

SUMMERY OF THE UTILITY MODEL

To the defect of above-mentioned prior art, the utility model provides a high-efficient cable of easily laying wire improves the tensile strength performance of conductor compliance assurance cable.

The utility model discloses technical scheme as follows: the utility model provides an easy high-efficient cable of wiring, from interior to exterior includes cavity pipe, conductor layer, non-woven fabrics around covering, inner sheath layer and oversheath layer in proper order, the conductor layer includes a plurality of centers on the insulating heart yearn of cavity pipe transposition, be equipped with a plurality of axially extended iron wires in the middle of the oversheath layer.

Preferably, the iron wires are located at circumferentially equally divided positions of the outer sheath layer.

Preferably, the number of the iron wires is 2-5.

Preferably, the pipe wall of the hollow conduit is provided with a plurality of through holes.

Preferably, a twisting pitch of the insulating core wire twisted around the hollow conduit is 10 to 12 times.

The utility model provides a technical scheme's advantage lies in:

the hollow guide pipe is arranged in the cable to form an air guide channel, so that the heat dissipation effect of the cable can be enhanced to improve the load of the cable. Set up double-deck sheath and set up the iron wire at the outer sheath layer, can reduce the ribbon to the extrusion of insulating heart yearn simultaneously in the model of buckling that keeps the cable, be favorable to complicated spatial position's wiring and guarantee the cable life-span.

Detailed Description

The present invention is further described in connection with the following examples, which are intended to illustrate the invention and not to limit the scope of the invention, which, after reading the present invention, are intended to cover modifications of the invention in its various equivalent forms by those skilled in the art, which fall within the scope of the appended claims.

The high-efficiency cable easy to wire related to this embodiment includes from inside to outside in proper order including hollow pipe 1, conductor layer, non-woven fabrics around covering 2, inner sheath layer 3 and oversheath layer 4, please combine shown in fig. 2, and hollow pipe 1 is inside to constitute airflow channel, is provided with a plurality of through-hole 1a on the pipe wall of hollow pipe 1. The plurality of insulating core wires 5 are twisted around the hollow conduit at a twisting pitch of 10-12 times to form a conductor layer. The conductor of the insulated core wire 5 adopts a VDE0295, 5-class flexible conductor, and the insulating layer of the insulated core wire 5 adopts a PVC material with the hardness of 90-95A. During cabling, the conductor layer is wrapped with flexible non-woven fabrics to form a non-woven fabric wrapping layer 2. Extrude PVC inner sheath layer 3 outside non-woven fabrics is around covering 2 and play the effect of protection insulating heart yearn 5. Extrude the PVC oversheath layer 4 that one deck hardness is 70 ~ 75A again outside inner sheath layer 3, drag four iron wires 6 according to circumferential equipartition position evenly distributed simultaneously in outer sheath layer 4, iron wire 6 is cable axial extension, and 6 quantity of iron wire are 2 ~ 5 generally, and single iron wire 6 is difficult to reach fine design effect, and 6 too many then influence the flexibility of cable of iron wire. Therefore, the cable is designed into a flexible wire, the wire is easy to bend, the minimum bending radius is 2 OD, and the problems of core wire breakage and the like are avoided. In use, a portion of the heat in the core wire is removed by the air flowing in the hollow conduit 1, so that the load through which the cable can pass is greatly increased. Iron wire 6 that sets up in outer restrictive coating 4 makes the electric wire when the wiring, and the electric wire plays the fixed action after buckling certain angle, avoids the electric wire to kick-back and warp, fixes the electric wire, has solved the indiscriminate problem of wiring.
