Description
Technical field
The utility model relates to cable technology field, and a kind of optoelectronic composite cable is provided.
Background technology
Existing cable is simple in structure, and shielding properties is poor mostly, cannot meet diamagnetic, anti-radio frequency, and anlistatig requirement, and present much cables do not merge optical cable.
From 1836, produce in the world Article 1 lv power cable (the wrapped copper conductor of rubber belt) so far, electric wire has developed into a large product category of many uses, various in style.China's wires and cables industry, through the development of more than 70 years, has also been obtained larger progress.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.At present approximately 5000 of the state-owned and above enterprises of scale of China's wires and cables industry, wherein large enterprise has 19, and the gross output value accounts for 11% of whole market share.
Electric wire is to carry the energy, the indispensable basic equipment of transmission of information, and from the today in social informatization, electrified fast development, electric wire has become one of most important basic product in economic construction.Wires and cables industry is again supporting industry, and product must meet the requirement of the each main industry of national economy to electric wire performance, and national economy thinks that most industries are all relevant to electric wire, and its industrial status is very important.China's wires and cables industry is still in developing stage at present, and as the important guide's industry of the development of the national economy, the growth of electric wire production and marketing index is generally higher than total value of production in national economy outline.
Summary of the invention
The object of the present invention is to provide a kind of screening ability strong, stretch-proof, has a kind of optoelectronic composite cable of cable and properties of optical fiber cable.
The present invention is in order to realize technique scheme, by the following technical solutions:
A kind of optoelectronic composite cable, its spy is, comprise at least 2 sub-thread cables, sub-thread circuit comprises at least 3 conductors 4, the outer all wrap insulate layers 6 of conductor, sub-thread cable conductively-closed layer 9 wraps up, filler 5 is filled in gap between screen 9 and sub-thread cable, and described screen 9 outer wrapping inner restrictive coatings 8, are provided with at least 3 optical fiber 1 in inner restrictive coating 8, optical fiber 1 is wrapped with water blocking layer 2, and inner restrictive coating 8 is wrapped with external sheath layer 3.
Described water blocking layer 2 comprises bonding successively reinforced layer, basic unit, water blocking layer and cover layer, described reinforced layer is copper mesh, basic unit and cover layer are nonwoven fabrics, water blocking layer is mica tape or glass fibre, water blocking layer 2 is subject to not allow to produce deformation after water, thereby can not push optical fiber because water blocking layer 2 expands, cause Optical Fiber Transmission rate to decline.
Described filling filler 7 is fireproof water-resisting tape, and it comprises mica layer, and mica layer two sides is adhering glass fiber mesh respectively, and the film that bonding one deck consists of water-proofing powder on fiberglass gridding forms water blocking layer.
Described filling filler 7 is glass fibre.
The utility model by the following technical solutions, so possess following beneficial effect:
The utility model watertight composition is not easy to expand, thereby avoided watertight composition, expanded by water, pushes optical fiber, thereby affects the problem of Optical Fiber Transmission efficiency.
The utility model screening ability is strong, diamagnetic, anti-radio frequency.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
