Drawings

FIG. 1 is a schematic view of the present invention;

in the figure: the cable comprises a cable core group 1, an inner sheath layer 2, a lining framework 3, a separator 4, a flame-retardant filling layer 5, a shielding layer 6, an armor layer 7, an outer sheath layer 8, an elastic lug 9, a pressing block 10, a first groove 11 and a second groove 12.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

As shown in fig. 1, a resistance to compression molded lines cable, including the cable core, a plurality of cable cores are formed with cable core group 1, the cladding of cable core group outside has the inoxidizing coating, be provided with insulating filling layer between the inboard a plurality of cable cores of inoxidizing coating, a plurality of cable core group outsides are provided with inner sheath layer 2, inner sheath layer center is provided with inside lining skeleton 3, be provided with a plurality of separators 4 between inside lining skeleton and the inner sheath layer, the separator is the arc along its length direction's two sides, be provided with a plurality of cable core groups between the adjacent separator, the cable core group, the separator, be provided with fire-retardant filling layer 5 between the inner sheath layer, inner sheath layer periphery side is provided with shielding layer 6, shielding layer outside is provided with armor 7, the armor layer outside is provided with oversheath layer 8, be equipped with a plurality of elastic convex block 9 on the oversheath layer inner wall, elastic convex block supports the armor. Furthermore, a pressing block 10 is further arranged on the inner wall of the inner sheath layer, and the cable core group is at least contacted with one of the pressing block or the separator. The cable core group and briquetting or separator contact can make the briquetting or the separator of contact take place deformation when receiving the extrusion, play the power of unloading cushioning effect, have protected the cable core, simultaneously, because the separator both sides are the arc, have increased the effect of buffering, have improved compressive property.
