To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：

A kind of high reliability data connecting line with shock-absorbing capacity, including the insulating barrier for wrapping up successively from outside to inside, prevents Fire screen absciss layer, thin aluminium powder layer, metal protection layer and silicone rubber inner sheath；The outer wall of insulating barrier passes outwardly connecting portion and is connected with steel Cable protection layer, is inserted with the steel wire rope parallel with insulating barrier in wirerope protective layer；Filler layer, silicon are provided with inside silicone rubber inner sheath Rubber inner sheath is provided with four silicone rubber projections that section is arc along inner surface, and it is empty that each silicone rubber lobed interior is provided with buffering Chamber, between adjacent silicon rubber bumps draw-in groove is formed, and is provided with each draw-in groove while the twisted-pair feeder being against on filler layer.

Further, insulating barrier includes one layer of composite fire band and respectively the inside and outside all composite fire bands One gold mica tape, the second gold mica tape, the first gold mica tape, composite fire band and the second gold mica tape are wrapped in successively metal to be prevented Insulating barrier is formed on the outer peripheral face of sheath.

Further, insulating barrier outside be provided be added with capsaicin only nibble layer, can solve the problem that cable be easily subject to Mus, Biting for ant etc., causes cable failure, the problem of product reliability difference.

Compared with prior art, the beneficial effects of the utility model：

This utility model strengthens the structural strength of whole data connecting line by arranging wirerope protective layer, steel wire rope, to prolong The service life of long data connecting line；Twisted-pair feeder is four silicone rubber projections by being arranged at silicone rubber inner sheath along inner surface It is secured firmly in it, by increasing frictional force, improve integrally-built stability, and silicone rubber it is raised in arrange Buffer cavity, increased the shock-absorbing capacity of structure, reduce impact, destruction of the outside huge power to twisted-pair feeder, also contribute to number According to the radiating of connecting line；Filler layer is provided with inside silicone rubber inner sheath, is allowed to fix multiple twin with silicone rubber male cooperation Line, it is further to lift its stability.
