By such scheme, in pancake oversheath, be provided with inner sheath, described inner sheath is coated on outside non-metal reinforcement member.
By such scheme, the middle part of described pancake oversheath lateral cross section is butterfly, two ends are circular, in the middle part of butterfly and circular two ends are linked into one, optical communication element is installed in the middle part of butterfly, install power line and digital signal line in the one end at circular two ends, the other end installs ground wire and level signal line.
By such scheme, described pancake oversheath lateral cross section is kidney ellipsoid (track type), power line and digital signal line is installed in one end, circular two ends, the other end installs ground wire and level signal line, described optical communication element is installed in separately middle part, or merges with ground wire and level signal line and be installed in the other end in oversheath.
By such scheme, described optical communication element is optical fiber and/or fibre ribbon, and the core number of optical fiber or fibre ribbon is 4 cores, 6 cores, 8 cores or 12 cores.
By such scheme, described non-metal reinforcement member is aramid yarn, polyester fibers or glass fiber yarn.
By such scheme, described power and ground forms and coated insulation layer by multiply copper conductor is stranded.
By such scheme, described oversheath is made up of the macromolecular material of anti-flammability and the excellent polyurethane of flexility or other function admirable.
The beneficial effects of the utility model are: 1, structure is simple, arrange rationally, have good mechanical performance and environmental performance, can use under comparatively mal-condition; 2, optical communication element is transmission medium, and transmission range is long, transmission capacity is large, and transmission speed is fast, can meet the super 5Gbps HD video within 200m and audio signal transmission requirement; 3, in composite rope, each unit arranges rationally, and the electric capacity between ground wire and digital signal line is minimum, and the interference of external electromagnetic signal on level signal line and digital signal line can be cancelled out each other, and meets the procotol requirement of HDMI cable completely; 4, not only optical communication element has fabulous difference and to continue performance, and other communication units also have good welding performance, greatly facilitates composite rope later stage joint and connector makes; 5, composite rope volume is little, lightweight, bending property is excellent, be highly suitable for the connection conduction between electronic devices and components and product, and computer hardware, crawl space in components and parts, make optoelectronic communication and consumption electronic products rapider in the operation at photoelectricity interface.
