Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this practicality
It is new, it is not used to limit the utility model.
The application principle of the utility model is explained in detail below in conjunction with the accompanying drawings.
Machinery as shown in Figure 1 makes cable with dragging, including core component and exterior cover sheets 6, the core component bag
Include multiple power wire cores 1 and multiple control conductor groups 5.
The control conductor group 5 includes more control conductors 2 and a tensile elements 3, and the tensile elements 3 are located at
The center location of control conductor group 5, control conductor 2 are circumferentially arranged around tensile elements 2, and in the outermost of control conductor group 5
Layer cladding layer protective layer 4, can increase control conductor 2 by the way that more control conductors 2 are wrapped in a control conductor group 5
Tensile property.And the macromolecular fibre rope that the tensile elements 3 at 5 center of control conductor group are superhigh intensity, such as nylon or
Aramid fiber rope, the cordage are stranding into by multiply fiber harness.The pull-off force of the tensile elements line 3 is not less than cable
100 times of dead weight, can bear the gravity of most of external force that control conductor is subject to and cable itself, be effectively reduced control line
The external stress that core conductor is subject to；Simultaneously because the very light softness of polymer fiber material, therefore cable bend will not be made
With impacting.
The power wire core 1 and control conductor 2 include the bullet of internal metallic conductor 11,21 and coated metal conductor
Property insulating outer layer 12,22.
The problem of in order to avoid the Long-term bend of cable causes the local stress of cable uneven and produces fracture, this practicality
New cable design is pancake, and relative to round cable, pancake cable is more soft, using smaller restoring force just
Cable can be made to restore to the original state.In order to make cable surface more flat, reduction local stress is excessive, and the cladding is elastic insulated outer
The outside diameter of the power wire core 1 of layer 12 is identical with the outside diameter of control conductor group 5.In same level, 1 He of power wire core
Control conductor group 5 replaces arranged at equal intervals in exterior cover sheets successively, and this symmetrical balance structure can guarantee that cable is being born
When frequent U-bend is bent, internal each element uniform force and relative displacement will not be produced.So as to avoid cable Long-term bend from sending out
The problem of shape that changes.
Multipair semi-circular recesses 7, each pair semi-circular recesses 7 are set in the upper and lower surface of the exterior cover sheets 6 at the same time
In the center of 5 line of adjacent power core 1 and control conductor group, the internal diameter of the semi-circular recesses 7 is 2.0mm-
5.0mm.This design can effectively disperse the transverse direction between power wire core 1 or control conductor group 5 and outer jacket during cable U-bend
Mechanical stress, enhances the resist bending and wear-resisting property of protective coverings of cable.Semi-circular recesses are correspondingly arranged up and down so that scattered to answer
Power is more uniformly distributed, and is not easy to cause to damage to local.
The outer jacket 6 is wrapped up power wire core 1 and control conductor group 5 inside it by the way of screw extruding
In space, integrative-structure is formed.Internal core can be effectively fixed, displacement, deformation are not susceptible in BENDING PROCESS.
In the embodiment of the utility model, the metallic conductor 11,21 inside the power wire core 1 and control conductor 2 has
Soft copper silk bundle strand forms, a diameter of 0.20mm-0.50mm of soft copper silk used, elongation at break 25%-35%, metallic conductor
11,21 synnema lay ratio is 16-20 times, and it is 10-12 times to be twisted lay ratio, and the metallic conductor inside all cores is according to same
One direction bundle strand.
In order to reduce influence of the extraneous stress to metallic conductor 11,21, the elastic insulated outer layer 12,22 of setting uses butyronitrile
Elastomer blends or EP rubbers mixture, the protective layer 4 and exterior cover sheets 6 are neoprene mixture, gather
One kind in ester elastomer mixture, butyronitrile elastomer blends.These high molecular materials can absorb and dispersive stress, reach
The effect of buffering, and quickly metallic conductor can be driven to return to reset condition after external force elimination, it is effectively protected inside
Power wire core and control conductor.
The advantages of basic principle and main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Simply illustrate the utility model principle, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed scope is defined by the appending claims and its equivalent thereof.
