The insulating layer of the conductor and its outside that are twisted.The interior outer jacket of the cable is all made of elastomeric material, in addition, on the outside of conductor
Insulating layer be elastomeric material, while playing good insulation effect, together form Pleiotropic Protections with interior outer jacket,
It is suitable as arm and various connecting lines in robot device, torsibility is can be applied to and resistance to shroud bending stress exists simultaneously
Various occasions, cable it is not easy to break and abrasion, long service life.
With the extensive use of express elevator, high speed crane and industrial robot, to the resistance to bend(ing) energy of cable, bending resistance
More stringent requirements are proposed for folding endurance energy, wear-resisting property, mechanical strength, flexibility, load etc..Novel resist bending flexible cable requirement
It is able to bear the speed of service of 120-180m/min, 150 meters of vertical run height or more, there is good acid resistance, weather-proof
Property, alkali electroless corrosion and fuel tolerance capability, and shine upon down non-reflective, operating temperature is generally at -40 DEG C -90 DEG C；Use the longevity
Life requires to be 3 to 20 years.Traditional resist bending flexible cable is used for original workplace, and normal service life is generally at 24
Month or more, and it is used for after high speed goes up and down occasion, the case where the deformation that is easily distorted, sheath cracking, insulated wire cores are broken core
Probability and frequency greatly increase, or even some comes into operation in half a year there have been torsional deformation, serious curtailment service life,
Bring great security risk and economic loss.
Summary of the invention
In view of the deficiencies of the prior art, the invention proposes a kind of resist bending flexible cables, it is therefore intended that it is soft to make up tradition
Property cable high speed lifting operating condition in be easily distorted deformation, sheath cracking and insulated wire cores break core deficiency.

Discarded use after the bad phenomenons such as breakdown no longer carries out repair process to insulated wire cores.
The invention has the following beneficial effects:
(1) conducting wire of resist bending flexible cable of the present invention be first by 10 or more monofilament according to same direction bundle strand at primary stock
5 strands or more of primary strand is twisted into strand unit, the direction of lay phase of the direction of lay of strand unit and primary strand by line
Together, then by 5 strands or more of strand unit it being twisted into final conducting wire again, when twisting again, the strand unit direction of lay of same layer is identical, and
It is identical that direction is twisted again with the layer, and adjacent layer twists contrary again, and outermost layer twists direction again as the right side.This structure can guarantee to lead
Under the premise of body has excellent flexibility, good resistance to twisting property, utmostly improve conductor holds lotus ability, is promoted
Break resistance and anti-torsion performance of the cable in high speed lifting operating condition.
(2) resist bending flexible cable of the present invention has abandoned the filling such as traditional PP filling rope, the rope made of hemp, cotton cord, PVC packing
Material uses insulating materials instead and extrudes packing, and substitutes flexible carbon steel cord in the center of packing setting aramid line.Aramid fiber
Line is twisted by the fine sub-thread twisting aramid yarn of 3 strands or more 2000D or 3000D long, and the intensity of aramid line is flexible carbon steel wire
4-6 times of rope, modulus are 2-3 times of flexible carbon steel cord, and toughness is 2 times of flexible carbon steel cord, the contraction at 150 DEG C
Rate is 0.On the one hand improve the load-carrying ability of packing in the center of packing setting aramid line, reduce insulated wire cores by
Drawing force, on the other hand enhance whole flexibility, the structural stability, rounding property of cable core, thus make cable core have it is stronger
