Abstract
The invention relates to the technical field of optical cables, and relates to a multi-core waterproof optical cable. The multi-core waterproof optical cable comprises an optical cable sheath. Multiple optical fibers are arranged inside the optical cable sheath in parallel and in a penetrating way. Each optical fiber is coated with a loose casing, a water-blocking glass fiber and a polyethylene sheath sequentially from inside to outside. Water-blocking glass fibers fill the space between the optical cable sheath and the multiple polyethylene sheaths. The multi-core waterproof optical cable has an excellent waterproof effect, and has high resistance to high temperature.
Description
Technical field
The present invention relates to the technical field of optical cable, especially a kind of multicore waterproof cable.
Background technology
Optical cable is one of requisite communication apparatus in our daily life, due to long-term being buried under the ground of the optical cable had, so be subject to the erosion of underground moisture vapor for a long time, easily can occur the phenomenon of communication quality difference; Some optical cables work for a long time under the sun, there will be the phenomenon that aging, sheath comes off, and then easily cause short circuit and fire hazard accident, there is very large security hidden trouble.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problem proposed in above-mentioned background technology, the invention provides a kind of multicore waterproof cable, not only possesses excellent waterproof effect, also possess good resistance to elevated temperatures simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of multicore waterproof cable, there is cable jacket, the interior parallel of described cable jacket is equipped with organizes optical fiber more, and the described outside often organizing optical fiber is coated with Loose tube from the inside to the outside successively, block water glass fibre and pe sheath; The glass fibre that blocks water is filled with in space between cable jacket and multiple pe sheath.
Further, in order to improve the resistance to elevated temperatures of optical cable, therefore the cable jacket described in technique scheme is made up of PE material.
Further, in order to improve structural strength and the plasticity of optical cable, therefore the inwall of the cable jacket described in technique scheme is attached with plastic-coated aluminium strip.
Further, in order to improve the structural stability of optical cable, therefore the quantity of the optical fiber described in technique scheme is three groups, and the cross sectional shape of described cable jacket is equilateral triangle.
Beneficial effect of the present invention: multicore waterproof cable of the present invention, often the glass fibre that blocks water organized outside optical fiber can resist the erosion of external water source, what many groups outer fiber was arranged jointly block water, and glass fibre also can play the effect of waterproof on the whole, effectively avoid optical cable to be subject to the erosion of external moisture, and then ensure the work that optical cable is normally orderly; Simultaneously, by adopting the cable jacket of PE material, the resistance to elevated temperatures of whole optical cable is greatly improved, and effectively avoid optical cable under high-temperature work environment, occur the phenomenon that aging, sheath comes off and cause short circuit and fire hazard accident, use safety problem obtains guarantee.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Label in accompanying drawing is: 1, optical fiber, 2, Loose tube, 3, block water glass fibre, 4, pe sheath, 5, cable jacket, 6, plastic-coated aluminium strip.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Multicore waterproof cable of the present invention as shown in Figure 1, has cable jacket 5, and the interior parallel of cable jacket 5 is equipped with many group optical fiber 1, often organize optical fiber 1 outside is coated with Loose tube 2 from the inside to the outside successively, block water glass fibre 3 and pe sheath 4; The glass fibre 3 that blocks water is filled with in space between cable jacket 5 and multiple pe sheath 4.
Wherein, cable jacket 5 is made up of PE material, plays a protective role, be convenient to the installation of optical fiber and move the combination of many groups optical fiber 1 of entirety.The inwall of cable jacket 5 is attached with plastic-coated aluminium strip 6, improves structural strength and the plasticity of optical cable.The quantity of optical fiber 1 is three groups, and the cross sectional shape of cable jacket 5 is equilateral triangle, improves the structural stability of optical cable.
Because optical cable is very fragile, frangibility, therefore be coated with Loose tube 2 in the outside of optical fiber 1, Loose tube 2 can play the effect of a protection to optical cable.The outside of Loose tube 2 is coated with the glass fibre 3 that blocks water, and can play the effect of a waterproof, prevents the erosion of external humidification air from impacting optical cable.The block water outside of glass fibre 3 is coated with pe sheath 4, can be independent to the effect often organizing optical fiber and play a protection.
Be filled with the glass fibre 3 that blocks water in space between cable jacket 5 and multiple pe sheath 4, this glass fibre 3 that blocks water can play the effect of a waterproof to many groups optical fiber 1 of entirety, ensures the normal communication of optical fiber 1.
This multicore waterproof cable, often the glass fibre 3 that blocks water organized outside optical fiber 1 can resist the erosion of external water source, the outside common glass fibre 3 that blocks water arranged of many groups optical fiber 1 also can play the effect of waterproof on the whole, effectively avoid optical cable to be subject to the erosion of external moisture, and then ensure the work that optical cable is normally orderly; Simultaneously, by adopting the cable jacket 5 of PE material, the resistance to elevated temperatures of whole optical cable is greatly improved, and effectively avoid optical cable under high-temperature work environment, occur the phenomenon that aging, sheath comes off and cause short circuit and fire hazard accident, use safety problem obtains guarantee.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on instructions, must determine its technical scope according to right.
