The utility model discloses further set up to: the filling layer is evenly divided into four areas by the isolation blocks.

Through adopting above-mentioned technical scheme, when receiving external force extrusion, because the spacing block separates the filling layer for four regions, and then avoid a plurality of silica gel strips to drunkenness at will and produce and pile up, effectively improved structural stability.

The utility model discloses further set up to: the isolation blocks are made of TPE materials.

Through adopting above-mentioned technical scheme, the spacer block uses the material to be the TPE material, outside the effect of isolation filler, and self also has higher elasticity, can provide good buffering effect equally.

The utility model discloses further set up to: the sheath adopts the TPE material to make, and a plurality of spacer block integrated into one piece is close to the one side of shielding layer in the sheath.

Through adopting above-mentioned technical scheme, integrated into one piece can make the cable when receiving external force, and the spacing block can also can exert cushioning effect better with the power dispersion that receives, and the sheath is the TPE material with the spacing block the same in addition, and itself has when higher elasticity, also has good wearability and corrosion resistance.

The utility model discloses further set up to: the shielding layer is formed by wrapping aluminum foil mylar.

By adopting the technical scheme, the aluminum foil mylar has an anti-interference effect and also has higher flexibility.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the use of the filler and the filling layer has high elasticity and good buffer effect. And the buffer layer adopts a double-layer arrangement mode, so that the buffer effect is further improved.

2. Adopt spacing block and sheath integrated into one piece's mode, dispersed the external force that receives, and because the spacing block material is TPE high elastic material, except the effect of keeping apart the filling layer, the cushioning effect that itself is also good.

3. The sheath is made of TPE materials, has high elasticity, high wear resistance and strong corrosion resistance, and further prolongs the service life of the cable.
