Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of inner and outer pipes hollow elasticity bend resistance control cables, avoiding bending damage to cable, and the impact on electric current or signal transmission quality.
A kind of inner and outer pipes hollow elasticity bend resistance control cables that the present invention proposes, comprising:
Interior pipe is hollow-core construction; Outer tube, is set in outside interior pipe; Multiple hollow pipe is provided with between inner and outer tubes; Rest is between the inner and outer pipe sections filled with padded coaming;
Multiple conductor, is located in interior pipe; Described conductor comprises: heart yearn, is positioned at conductor center; Insulating barrier, is located at outside described heart yearn; Armour, is located at outside described insulating barrier; In interior pipe, clearance spaces fills padded coaming.
Preferably, the first watertight composition is provided with at described outer wall of inner tube.
Preferably, the second watertight composition is provided with at described outer tube outer wall.
Preferably, the distance between outer wall of inner tube to outer tube wall and hollow pipe diameter matches.
Preferably, hollow pipe is evenly distributed on circumferentially or is evenly distributed on multilayer circumferentially;
Preferably, hollow pipe is hollow dielectric resilience pipe.
Preferably, in hollow pipe, resilient support arms is provided with.
Preferably, the cross section of resilient support arms is criss-cross fashion.
Preferably, insulating barrier is polyvinyl chloride insulation layer or elastic polyurethane layer.
Preferably, armour is steel-tape armouring, LWA light wire armoured or thicker wire armouring.
In the present invention, multiple conductor is located in interior pipe, arranges hollow pipe between inner and outer tubes, and when whole cable is by external force bending, hollow pipe crimp, plays cushioning effect to external force; And after external force disappears, hollow pipe recovers under natural resiliency effect, ensure that the straight of whole cable, does not affect electric current or signal transmission quality.

Embodiment
The embodiment of the present invention 1 proposes a kind of inner and outer pipes hollow elasticity bend resistance control cables, as shown in Figure 1, comprising: interior pipe 1, is hollow insulated tube, uses elastic insulating material to make; Outer tube 2, be set in outside described interior pipe 1, be provided with multiple hollow pipe 10 between interior pipe 1 and outer tube 2, hollow pipe 10 is evenly arranged, such as even distribution circumferentially or be evenly distributed on multilayer circumferentially; Many conductors 1, are located in described interior pipe 1; Described conductor comprises: heart yearn 3, and it also can form to improve heart yearn intensity for multiple conducting wires is stranded for solid conductor; Insulating barrier 4, is located at described heart yearn 3 outer to make to insulate between each heart yearn, such as polyvinyl chloride insulation layer or elastic polyurethane layer; Armour 5, is located at outside described insulating barrier 4, and be layer of metal protection, to increase the mechanical strength of cable, improve erosion prevention, avoid heart yearn to be damaged when transporting and install, armour 5 can be steel-tape armouring, LWA light wire armoured or thicker wire armouring; Rest between interior pipe 1 and outer tube 2 is filled with padded coaming 11, and in interior pipe 1, clearance spaces fills padded coaming 6, such as asbestos material etc., produces loss to avoid the mutual friction of heart yearn phase.
In the embodiment of the present invention 2, in order to increase the water resistance of cable, can watertight composition be set up, as shown in Figure 2, being provided with the first watertight composition 7 at described interior pipe 1 outer wall, avoid cable to grow water infiltration cable core service time, produce corrosion.
In the embodiment of the present invention 3, be provided with the second watertight composition 8 at described outer tube 2 outer wall, as shown in Figure 3, avoid the water in environment enter cable core from outer wall and produce corrosion.
In the embodiment of the present invention 4, simultaneously at interior pipe 1 outer wall the first watertight composition 7 is set and at outer tube 2 outer wall second watertight composition 8, as shown in Figure 4.
In the embodiment of the present invention 5, be provided with resilient support arms 9 in described hollow pipe, such as, the cross section of resilient support arms is criss-cross fashion etc., as shown in Figure 5, is out of shape under pressure, restore to the original state after distress resolves, the cushioning effect of hollow pipe can be ensured further.
