Has the advantages that: compared with the prior art, the utility model has the advantages of it is following: the utility model discloses, with few materials, the dead weight is light, possesses good shock resistance ability and compressive capacity.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of a first wrapping layer;
the cable comprises a conductor 1, an insulating layer 2, a second wrapping layer 3, a first wrapping layer 4, an outer sheath 5 and a central bearing core 6.
Detailed Description
The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.
As shown in figure 1, the novel central force-bearing flexible communication cable comprises a conductor 1, an insulating layer 2, a second winding layer 3, a second winding layer 4, an outer sheath 5 and a central force-bearing core 6. The central bearing core 6 is positioned in the center of the cable and comprises an annular edge, wherein the edge is made of insulating materials, and a honeycomb structure is fully distributed in the edge. The honeycomb structure has strong stability and improves the bearing capacity of the cable. And materials are saved, and the production cost is reduced.
The conductor 1, the insulating layer 2 and the second wrapping layer 3 form a pair-twisting unit. Insulating layer 2 wraps conductor 1 and constitutes a sinle silk, and two sets of sinle silks are twisted in pairs, and the second wraps two sets of sinle silks around covering 3 parcel. The 12 pairs of twisted units are twisted on the outer ring of the central bearing core 6, and the 12 pairs of twisted units 3 are uniformly distributed around the central bearing core 6 and face each other on the cross section. The pair twist unit is externally sleeved with a first wrapping layer 4. The first wrapping 4 is a double wrapping, as shown in fig. 2. The wrapping directions are opposite, and one is anticlockwise and the other is clockwise. Make originally compact, closely knit around the covering. The phenomena of bulging, concave-convex and the like are not easy to occur on the surface of the finished cable product. The outer lane of first covering 4 is around a polyurethane outer sheath 5, is equipped with the buffer ring in the outer sheath 5, and the buffer ring is a wavy airtight curve. The composition unit of the curve is an S-shaped structure formed by two semicircles, and the S-shaped structure circularly forms the curve. The buffer ring is a styrene thermoplastic elastomer, and can provide buffer when being impacted by the outside, reduce the impact force on the inner conductor and improve the flexibility of the cable. The semicircular arc-shaped part is in contact with the two walls of the outer sheath, so that abrasion of the buffer ring on the two walls when the buffer ring plays a buffer role is reduced when the buffer ring is impacted.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
