Abstract
The invention belongs to the technical field of cables and relates to a skeleton-type cable. The skeleton-type cable comprises a skeleton, a reinforcer, cable cores and a jacket. Inner skeleton grooves are formed outside the skeleton; and the inner skeleton grooves are parallel to each other and are parallel to the reinforcer. The skeleton-type cable is characterized in that an inner skeleton is provided with a first groove and a second groove which are adjacent to and are not communicated with each other; the first groove and the second groove are positioned in the two adjacent inner skeleton grooves; the outer edge of the jacket is provided with outer skeleton bars protruding out of the outer edge of the sheath; the outer skeleton bars are distributed in parallel and are parallel to the reinforcer; the outer skeleton bars correspond to the positions of the inner skeleton grooves; on the projection of the bottom surface of any one inner skeleton groove, the bottom surface of the outer skeleton bar at the corresponding position is positioned in the bottom surface of the inner skeleton groove or has the same size with the bottom surface of the inner skeleton groove; and the middle points of the bottom lines of the outer skeleton bars at the corresponding positions, the middle points of the bottom lines of the inner skeleton grooves and the center of the reinforcer are positioned on the same straight line. The skeleton-type cable has the following beneficial effects of simplicity for manufacturing, easiness for batch production, convenience for construction and more effective protection on the cable.
Description
the application is that denomination of invention is: a kind of skeleton type cable, number of patent application are: 201210103170.3, the applying date is: the divisional application of the application for a patent for invention on April 7th, 2012.
Technical field
the invention belongs to technical field of cables, especially relate to the skeleton type cable on a kind of sheath with skeleton grooves or skeleton bar.
Background technology
skeleton type cable is widely used, particularly optical cable aspect, the communication industry standard YD/T981.1-2009 of People's Republic of China (PRC) Access Network optical fibre band optical cable part 1: skeleton, just specify the good multiple optical cable with skeleton, slotted core cable is normally made up of skeleton, central reinforce member, band and moisture-proof layer, sheath, optical fiber or fibre ribbon, on skeleton, have multiple skeleton grooves, optical fiber or fibre ribbon are placed in skeleton grooves, and skeleton grooves is one-way spiral or forward and reverse spiral.For skeleton cable, the substantially same slotted core cable of structure, what only in skeleton grooves, place is communication or power lead.For the ease of identification, conventionally on skeleton, there is skeleton grooves mark line.This skeleton type cable of the prior art has significant shortcoming: at optical cable not stripping sheath in the situation that, very not easy to identify, and in construction, often need accurately to know the position of optical fiber or fibre ribbon or electric wire place groove, in prior art, only have after being cut and could judge exactly, quite large for the injury of cable.
