Abstract
The invention relates to the technical field of optical cable, in particular to a shock resistant optical cable which is composed of a cable core, a protective layer outside the cable core and a jacket layer wrapped outside the protective layer. The invention is characterized in that a plurality of grooves are distributed on the jacket layer along the axial direction of the cable core; and on any cross section, gaps exist between the bottom of the grooves and the outer edge of the protective layer. In the invention, with the existence of grooves, when the optical cable is shocked, force is dispersed to the grooves; therefore, the optical cable can bear stronger shock force; the performance of optical cable is more stable, and the consumption of the jacket layer of optical cable is smaller and cost is lower; and after external force withdraws, the elasticity jacket layer is easy to restore.

Summary of the invention
The objective of the invention is to address the above problem, a kind of shock proof optical cable is provided, it is realized by the following technical solutions:
A kind of shock proof optical cable, it mainly by cable core, be positioned at the outer protective layer of cable core, be coated on that the outer restrictive coating of protective layer constitutes; It is characterized in that: restrictive coating upper edge cable core axial distribution has a plurality of grooves; On arbitrary cross section, be gapped between the outward flange of bottom portion of groove and protective layer.
Above-mentioned described shock proof optical cable, its feature also is: described cable core is optical cable core or cable conductor or the compound cable core of photoelectricity.
Further, above-mentioned described shock proof optical cable, its feature also is; When described cable core is optical cable core, comprise an optical fiber in the cable core at least; When described cable core is cable conductor, comprise a conductor wire core in the cable core at least; When described cable core is the compound cable core of photoelectricity, comprise a conductor wire core and an optical fiber in the cable core at least.
Further, above-mentioned described shock proof optical cable, its feature also is: described optical fiber is positioned at protection tube, and protection tube is metal or nonmetallic; Described conductor wire core is made of conductor and insulating barrier, and conductor is positioned within the insulating barrier.
Above-mentioned described shock proof optical cable, its feature also is: described protective layer is one or more layers; During one deck, its material is steel band or aluminium strip or glass fiber tape; During multilayer, internal layer is waterstop or polyester belt or nonwoven fabrics or mica tape or water blocking yarn or aramid yarn, and skin is steel band or aluminium strip or glass fiber tape.
Above-mentioned described shock proof optical cable, its feature also is: described restrictive coating is plastics, preferred low density polyethylene (LDPE) or medium density polyethylene or high density polyethylene (HDPE) or low smoke and zero halogen polyethylene or low-smoke low-halogen polyethylene or or smokeless halogen-free polyvinyl.
Above-mentioned described shock proof optical cable, its feature also is: described a plurality of grooves are equal-sized or unequal.
Above-mentioned described shock proof optical cable, its feature also is: described a plurality of grooves are to be arranged on the restrictive coating symmetrical or asymmetricly.
Above-mentioned described shock proof optical cable, its feature also is: the minimum value in the gap between the outward flange of described groove and protective layer is 0.3mm.
Above-mentioned described shock proof optical cable, its feature also is: the one-tenth-value thickness 1/10 of described restrictive coating is 0.8mm-3.0mm.
Among the present invention because the existence of groove, so optical cable when being subjected to impulsive force, power is dispersed to groove; Therefore, optical cable can bear higher impact force; The performance of optical cable is more stable, and simultaneously, the restrictive coating of optical cable consumes still less, and cost is lower; And after external force was withdrawn, restrictive coating is elastic return very easily.
