Field, more particularly, to a kind of rat destruction cable.The resistance to compression that cross section is in vortex shape is equipped between the protective jacket and core group
Shielded rack, has the gap in vortex shape on the resistance to compression shielded rack, equipped with can send out after several shakings in the gap
The small bell of sound is filled with foamed plastic layer, the resistance to compression shielded rack and protection between the resistance to compression shielded rack and core group
Be successively arranged from the inside to the outside between set buffer layer and it is anti-tear sting layer, it is described it is anti-tear sting be equipped between layer and protective jacket and meet air after
Can spontaneous coagulation glue layer, be coated with rat destruction dye layer on the protective jacket outer wall.Disadvantage is that: this kind of rat destruction cable
Crushing resistance it is poor, internal structure is subject to be damaged.
Utility model content
The purpose of the utility model is to provide a kind of good cables of crushing resistance.
In order to realize above-mentioned purpose of utility model, a kind of resistance to compression cable of the utility model is adopted the following technical scheme that
A kind of resistance to compression cable, it is characterised in that: the cylindrical spring body including being set to center, periphery are radial outward
Multiple boss are protruding with, the elastomer periphery is coated with fixing sleeve, and the fixing sleeve, which corresponds at boss, to be provided in radiation
The isolation board of shape is provided with conductor between the isolation board of adjacent lands, and the isolation board end is contacted with separation layer inner ring, same convex
Support plate is provided between the isolation board of platform two sides, described support plate one end is contacted with boss, and the other end is contacted with separation layer inner ring,
Flame-retardant layer, protective layer, wearing layer are also successively coated with outside the separation layer.
When utility model works, pressure is applied to this kind of cable outer surface, pressure is transferred to elastomer, and elastomer generates
Power so that be transferred to support plate by boss by the trend of deformation, and power is being transferred to separation layer by support plate, so that pressure be let out
It goes.
Compared with prior art, the utility model has the beneficial effects that: external force is passed through branch by the deformation by elastomer
Fagging is transferred to separation layer inner ring, will be applied to the external force venting of conductor, maintains the stabilization of structure, improve the resistance to compression of cable
Ability.
The conductor includes the core of surface cladding insulating layer, the insulating layer, fixing sleeve, isolation board and separation layer inner ring
Filled layer is provided in the region of formation.
The separation layer inner ring corresponds to support plate and opens up fluted, and the support plate end is set in groove.
Rubber pad is provided between the slot bottom and support plate end of the groove.
There are four the boss, is distributed on the circumference of elastomer.
The elastomer is elastic rubber.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein, 1 elastomer, 2 boss, 3 fixing sleeves, 4 isolation boards, 5 insulating layers, 6 cores, 7 separation layers, 8 filled layers, 9 is recessed
