Abstract

The invention discloses a high tensile and bend resistant movable cable conductor. The cable conductor comprises a tensile wire layer positioned in an inner layer and formed by adopting a plurality of strands of aramid silk fiber strands and multiple strands and a conductor layer formed by respectively enwinding a plurality of homocentric tinning annealed copper wires or annealed bare copper wires on the tensile wire layer. The enwinding directions of each layer of tinning annealed copper wires or annealed base copper wires are opposite from inside to outside. The invention can be taken as the conductor of various movable cables; the cables can freely move, have smaller bending radius, and can freely move along with a movable device, and the conductor service life thereof can be improved to tens of times.

Description

A kind of high tensile, anti-crooked removal cable conductor

Technical field:

The present invention relates to cable conductor, a kind of high tensile of more specifically saying so, anti-crooked removal cable conductor.

Background technology:

Constantly increase along with China's economic construction constantly develops various mobile power equipment consumptions, the consumption of removal cable strengthens day by day.

At present, China uses the place of removal cable to have much all has a lot of mobile devices to need a large amount of removal cables as industries such as harbour, harbour, mine, metallurgy, mobile device needs to move around in the course of the work, be to connect between mobile device and the electrical power control cabinet at a distance with long cable, when mobile device work is arrived foremost, need retreat move left and right, in this process, cable will form the serious bending of the figure of eight, " N " font or serpentine and draw.The inner ring core of bending cable is subjected to very big pressure; the outer ring core is subjected to very big pulling force; and in when mobile device is walked; cable is formed longitudinal pulling force again; this makes cable conductor be easy to broken string; therefore require mobile device system should possess defencive function to the cable bending; but mobile device is difficult to accomplish at work; the structure of former conductor is a burst strand; the multiple concentric stranding again that twists afterwards; do not possess counter-bending ability yet; therefore just must consider to make cable conductor itself have certain counter-bending ability and resistance to tension; i.e. crooked certain certain radius of cable at a certain temperature; continuously several thousand times even up to ten thousand times and when being subjected to huge pulling force; cable still can keep normal operation; the conductor of cable does not break; but, also do not have a kind of conductor up to now with mobile device private cable of excellent bending resistance and stretching resistance performance.

Summary of the invention:

For overcoming the defective of prior art, the object of the present invention is to provide the removal cable conductor of excellent properties such as a kind of soft degree is good, high strength, high tensile, anti-bending, to adapt to the demand of different operating environment.

Technical solution problem of the present invention adopts following technical scheme:

A kind of high tensile, anti-crooked removal cable conductor, described cable conductor comprises: is in the employing multiply aramid fiber silk fiber thigh strand of internal layer and twists formed tension silk layer again, and,

Adopt many tin annealed copper wires or soft bare copper wire with one heart, layering is wound in the conductor layer on the described tension silk layer.

And the tin annealed copper wire that from-inner-to-outer is every layer or the winding direction of soft bare copper wire are opposite.

Compared with the prior art, beneficial effect of the present invention is embodied in:

1, the cable conductor tension silk layer among the present invention is to spin synthetic fibre silk fiber thigh strand and multiple strand with multiply high strength, and burst strand with twist again that direction is identical to be constituted, its tensile strength is 2～5 times of steel wire, be tens of times of copper wire, its percentage elongation is less than 4%, and the percentage elongation of copper wire is about 15～25%, and this kind high strength spins that the synthetic fibre silk fiber is high temperature resistant, bending resistance is strong, is fit to do the tension silk of various removal cable conductors.

2, the cable conductor layer among the present invention adopts thin tin annealed copper wire or soft bare copper wire layering to be wrapped on the high strength aramid fiber silk fiber, the winding direction that from-inner-to-outer is every layer is opposite, outermost winding direction is that left-hand twines, this version makes the envoy apart from very little, its length of conductor monofilament expansion back is 1.3～1.5 times of raw footage, cable is when crooked and dilatory, conductor layer is just as a spring, most active force all concentrates on high strength and spins on the tension silk layer that the synthetic fibre silk fiber makes, thereby has avoided cable conductor to be broken and bend disconnected effectively.

3, the present invention can be used as the conductor of various removal cables, and cable can move freely, and bending radius is little, and cable can move freely with mobile device, and the conductor of cable can be brought up to original more than tens of times useful life.

Description of drawings:

Fig. 1 is a structural representation of the present invention.

Number in the figure: 1 is tension silk layer, and 2 is conductor layer.

Below pass through embodiment, and the invention will be further described in conjunction with the accompanying drawings.

Embodiment, non-limiting examples is as described below:

Embodiment: referring to Fig. 1, the cable conductor of present embodiment comprises, be in the tension silk layer 1 of internal layer, it is to spin synthetic fibre silk fiber thigh strand and multiple strand with multiply high strength, and burst strand with twist again that direction is identical to be constituted, its tensile strength is 2～5 times of steel wire, be tens of times of copper wire, its percentage elongation is less than 4%, and the percentage elongation of copper wire is about 15～25%, this kind high strength spins that the synthetic fibre silk fiber is high temperature resistant, bending resistance is strong, is fit to do the tension silk of various removal cable conductors.

Conductor layer 2 adopts thin tin annealed copper wire or soft bare copper wire layering to be wrapped on the tension silk layer 1, the winding direction that from-inner-to-outer is every layer is opposite, outermost winding direction is a left-hand, this version makes that pitch is very little, its length of conductor monofilament expansion back is 1.3～1.5 times of raw footage, cable is when crooked and dilatory, conductor layer is just as a spring, most active force all concentrates on high strength and spins on the tension silk layer 1 that the synthetic fibre silk fiber makes, thereby has avoided cable conductor layer 2 to be broken and bend disconnected effectively.

Claims (2)

1, a kind of high tensile, anti-crooked removal cable conductor is characterized in that described cable conductor comprises: be in the employing multiply aramid fiber silk fiber thigh strand of internal layer and twist formed tension silk layer (1) again, and,

Adopt many tin annealed copper wires or soft bare copper wire with one heart, layering is wound in the conductor layer (2) on the described tension silk layer.
