Preferably, the resistance to compression layer includes cushion collar and rigidized cover, the cushion collar is set in outside collet, described to add Gu it is set in outside cushion collar.

By using above-mentioned technical proposal, the stop of rigidized cover and cushion collar can be once received when cable receives impact and is divided Dissipate so that impact force will not be conducted to cable easily, so as to be effectively protected to cable core.

Preferably, the cushion collar is made of foamed plastic.

By using above-mentioned technical proposal, foamed plastic can be made of all thermoplasticity and thermosetting plastics, be fabricated to This is relatively low, and there are many stomatas in expanded material, more preferable to the cushioning effect of ambient pressure.

Preferably, the rigidized cover is made of steel wire.

By using above-mentioned technical proposal, steel wire intensity is higher, and deformation is not susceptible to when being impacted, can be in outside Play the role of further protection to cushion collar.

Preferably, the oversheath is made of polytetrafluoroethylene (PTFE).

By using above-mentioned technical proposal, the corrosion resistance of polytetrafluoroethylene (PTFE) and its powerful, and be practically insoluble in all molten Agent, can the very effective various impurity by external environment obstruct in Exterior cable so that the environment inside cable can be held Cleaning is held in continuation of insurance.

Preferably, some cables core are provided centrally with strengthening core.

By using above-mentioned technical proposal, strengthening core can carry out cable core inside cable certain support, and Improve the tension and bending resistance of cable entirety.

Preferably, the strengthening core is made of zinc-coated wire.

By using above-mentioned technical proposal, the toughness and elasticity of zinc-coated wire are extremely strong, have very outstanding tensile strength, The tension and bending resistance of cable can further be improved.

Preferably, the cable core is made of red copper.

By using above-mentioned technical proposal, the other impurities contained in red copper are less, its electric conductivity is preferable, can be into one Step reduces loss of the electric energy during transmission.

In conclusion the utility model has the advantages that：

1st, by adding rigidized cover in Exterior cable, external force can sufficiently be divided under the action of external force is subject to Dissipate so that be not easy to influence the cable core inside cable from extraneous pressure, even if being subject to extraneous larger pressure, cable Core can also be normally carried out work；

2nd, the oversheath made of polytetrafluoroethylene (PTFE) is arranged in the most external of cable, can causes the outermost structure of cable With higher stability, it will not be influenced be subject to moist or other adverse circumstances and produce corrosion, be further ensured that cable Being capable of steady operation.
