Photoelectric comprehensive cable with irregular filling ropes

Abstract

The invention belongs to the technical field of cables, and in particular relates to a photoelectric comprehensive cable with irregular filling ropes. The photoelectric comprehensive cable comprises a reinforcing part, a plurality of transmission conductors which are arranged at the outer side of the reinforcing part and are sequentially tangential to each other or arranged at small intervals, optical fiber communication units positioned in outer gaps between the adjacent transmission conductors, protecting layers for wrapping the transmission conductors and the optical fiber communication units, and protecting cover layers which wrap the protecting layers by extrusion molding. The photoelectric comprehensive cable is characterized in that the irregular filling ropes are arranged in the outer gaps between the adjacent transmission conductors; each optical fiber communication unit is clamped into the corresponding irregular filling rope. According to the photoelectric comprehensive cable with the irregular filling ropes, the irregular filling ropes are manufactured from special material; the photoelectric comprehensive cable has the beneficial technical effects of being simple in structure, low in cost, outstanding in performance, convenient to construct and the like.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a photoelectric composite cable with special-shaped filling ropes. Background technique [0002] With the rapid development of the communication industry, the application of optical fiber cables and wires and cables is increasing. The use of photoelectric composite cables can make electricity and light directly enter the home, and operators do not need to apply for additional power loads. Therefore, they are more and more favored by operators. However, the existing photoelectric composite cable mainly has the following problems: (1) When the outer gap between the adjacent conductors is large, in order to make the composite cable round and round, the loose tube for containing the optical fiber also needs to be made into a large size. Increased cost; (2) The wire and the loose tube are stranded to form a cable core, and the outside of the cable core is wrapped with a yarn-like mat...

Problems solved by technology

However, the existing photoelectric composite cables mainly have the following problems: (1) When the outer gap between the adjacent conductors is large, in order to make the composite cable round and round, the loose tube that accommodates the optical fiber also needs to be made into a large size. Increased cost; (2) The wire and the loose tube are twisted to form a cable core, and the outside of the cable core is wrapped with a yarn-like substance, which is easy to damage the loose tube, causing abnormal optical signal transmission, and when the temperature changes significantly, the wrapping The substance damages the loose tube, thereby affecting optical communication, and the dressing material itself is expensive; (3) It is not easy to remove the loose tube by twisting the wire and the loose tube, and the dressing material needs to be cut before taking it out. It is easy to damage the cable core, and it is not easy to restore; and it is very troublesome to take out the loose tube
