Problems solved by technology

The bifurcated cable is bulky and difficult to coil and construct; it is easy to crush the connecting rib when coiling; moreover, the manufacture of this kind of cable is quite troublesome, and the qualified rate of finished products is extremely low
When a problem occurs in a single branch, the entire cable is basically scrapped

Abstract

The invention belongs to the technical field of a cable, and especially relates to an easily assembled self-supporting cable. The cable is composed of a cable part and a supporting wire part. The cable part comprises a cable core and a sheath layer. The cable core comprises power transmission conductors or optical fibers. The supporting wire part comprises tensile elements and a supporting wire protective layer. The cable part and the support wire part are mutually independent. A composite groove is arranged in the sheath layer. The composite groove is composed of a vertical groove and a horizontal groove. The horizontal groove does not contact with the edge of the sheath layer. Connection convex strips are connected out of the supporting wire protective layer. The connection convex strips are composed of vertical convex strips and horizontal convex strips. The supporting wire part is formed integrally. The vertical convex strips can be placed in the vertical slot. The horizontal convex strips can be placed in the horizontal groove. After assembly, the connection convex strips cannot be drawn out along the axis direction of the vertical groove. The cable has the advantages that the manufacturing method is simple, the yield of the finished product is high, the universality is high, the construction and winding are more convenient, the capacity of the cable can extended flexibly, the construction is convenient, and the comprehensive cost is low.

Description

[0001] This application is a divisional application for an invention patent application entitled: An easy-to-assemble self-supporting cable, the application date is: July 21, 2014, and the application number is: 201410346478.X. technical field [0002] The invention belongs to the technical field of cables, in particular to an easy-to-assemble self-supporting cable. Background technique [0003] As the basic industry of the national economy, wire and cable are developing more and more rapidly; cables usually have overhead, pipeline, direct burial, submarine and other laying methods. The overhead laying method is divided into non-self-supporting and self-supporting. In the self-supporting laying, since there is no need to install additional load-bearing steel strands, it can be laid at one time, so the construction cost and maintenance cost are greatly saved. Self-supporting cables in the prior art usually have hanging wires, connecting ribs, and cable parts; an integrated ...
