Edge layer and insulation screen, are provided with multiple supporting elements between the insulation screen and buffer layer, the supporting element material is
Elastic insulated rubber, can resist impact capacity well, and the outside protective layer of the buffer layer is followed successively by corrugated aluminium sheath and outer shield
Layer, the outer sheath material be polyvinyl chloride, between the insulating layer and insulation screen be equipped with waterstop, the insulating layer and
The second waterproof yarn is filled between waterstop.
As a further solution of the present invention: the steel strand wires are constituted by the steel wire of surface zinc-plated processing is twisted.
As a further solution of the present invention: the cable core is twisted by more copper free wires.
As a further solution of the present invention: the electrostatic screen layer is copper strip shielding.
As a further solution of the present invention: the insulating layer material is polyvinyl chloride.
As a further solution of the present invention: filling fire-proof high-temperature resistant material between the supporting element.
Compared with prior art, the utility model has the beneficial effects that the utility model passes through the first waterproof yarn of setting, the
Two waterproof yarns and waterstop, play block-water effect；It is provided with elastic insulated supporting element simultaneously, there can be preferably protecting against shock ability,
The service life for extending cable, reduces cost.
Detailed description of the invention

Yarn, 14- waterstop.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment one:
Referring to Fig. 1, in the utility model embodiment, a kind of cable of waterproof and protecting against shock, including sleeve 2, the set
Steel strand wires 1 are placed in 2 inside of cylinder, and the steel strand wires 1 are constituted by the steel wire of surface zinc-plated processing is twisted, and the steel strand wires 1 improve
The tensile capacity of cable is cable core 3 outside the sleeve 2, and the cable core 3 is twisted by more copper free wires, the sleeve 2
For separating steel strand wires 1 and cable core 3, prevent steel strand wires 1 and cable core 3 from rubbing, the cable core 3 is successively arranged the outward
One waterproof yarn 4, electrostatic screen layer 5, insulating layer 6 and insulation screen 7, the first waterproof yarn 4 can play the work that blocks water well
With the electrostatic screen layer 5 is copper strip shielding, and the electrostatic screen layer 5 can resist the interference of external information, the insulating layer 6
Be for protecting between core, the insulation of core and the external world, 6 material of insulating layer be polyvinyl chloride, the insulation screen 7
Multiple supporting elements 8 are provided between buffer layer 10,8 material of supporting element is elastic insulated rubber, can resist punching well
Ability is hit, fills fire-proof high-temperature resistant material 9 between the supporting element 8, improves fireproofing of cable ability, the buffer layer 10 is outward
