Problems solved by technology

This kind of skeleton cable in the prior art has significant disadvantages: it is difficult to identify without stripping the sheath of the optical cable, and it is often necessary to accurately know the position of the optical fiber or optical fiber ribbon or the slot where the electric wire is located during construction. In the prior art, it can only be judged accurately after cutting it, which will cause considerable damage to the cable

Abstract

The invention belongs to the technical field of cables, and relates to a skeleton type cable, which includes a skeleton, a reinforcement, a cable core, and a sheath; outside the skeleton, there are inner skeleton grooves; the inner skeleton grooves are parallel to each other and parallel to the reinforcement; It is characterized in that: there are adjacent first grooves and second grooves on the inner skeleton that are not connected to each other; the first groove and the second groove are located between two adjacent inner skeleton grooves; Along the outer skeleton strip protruding from the outer edge of the sheath, the outer skeleton strips are distributed parallel to each other and parallel to the reinforcement, and the outer skeleton strip corresponds to the position of the inner skeleton groove; on the projection of the bottom surface of any inner skeleton groove, The bottom surface of the outer skeleton strip at the corresponding position is located within the bottom surface of the inner skeleton groove or as large as the bottom surface of the inner skeleton groove; the midpoint of the bottom line of the outer skeleton strip at the corresponding position, the midpoint of the bottom line of the inner skeleton groove, and the The centers are on the same straight line. The invention has the following beneficial effects: simple manufacture, easy batch production, convenient construction, and more effective protection for cables.

Description

[0001] This application is a divisional application of the invention patent application with the invention name: a skeleton type cable, the patent application number: 201210103170.3, and the application date: April 7, 2012. technical field [0002] The invention belongs to the technical field of cables, in particular to a skeleton type cable with a skeleton groove or a skeleton strip on the sheath. Background technique [0003] Skeleton cables have been widely used, especially in terms of optical cables. The People's Republic of China Communication Industry Standard YD / T981.1-2009 Optical Fiber Ribbon Cables for Access Networks Part 1: Skeleton Type stipulates many kinds of optical cables with skeletons. , Skeleton optical cable is usually composed of a skeleton, a central strength member, a cable tie, a moisture barrier, a sheath, an optical fiber or an optical fiber ribbon, and there are multiple skeleton grooves on the skeleton, and the optical fiber or optical fiber ribbo...
