The optical fiber coaxial composite cable includes a coaxial cable and an optical cable, wherein the coaxial cable and the optical cable are connected together parallelly after being stranded respectively; the coaxial cable includes an internal conductor, an insulation layer, an external conductor layer, and an external sheath from internal to external; the optical cable includes an optical fiber, nonmetal reinforcement elements, an internal sheath, and an external sheath from internal to external; the external sheath of the coaxial cable and the external sheath of the optical cable are connected together parallelly through hanging ribs; the cross section of the internal sheath is in a butterfly shape, and the nonmetal reinforcement elements are distributed at two sides of the optical cable in a symmetrical manner and arranged in the internal sheath; and the interval between the internal sheath and the external sheath is hollow. In the optical fiber coaxial composite cable, a coaxial cable unit is integrated with a butterfly-shaped introducing optical cable unit, so that mounting space is saved effectively, secondary wiring is avoided, construction cost is reduced, and simultaneous optical fiber communication and radio frequency signal transmission are achieved.

Description

A kind of fiber-coaxial composite rope

Technical field

The utility model belongs to a kind of optoelectronic composite cable, relates to a kind of fiber-coaxial composite rope; Be applicable in community, the access of the fiber broadband in building, radio signal transmission.

Background technology

Intelligent building is the sign of modern city, and in recent years, along with in succession the building up of fiber optic network and each floor height speed broadband access network, computer network are day by day universal, optical fiber possesses high performance communication media and has been widely applied among intelligent building as a kind of.But the appearance of optical fiber does not allow traditional copper cable exit the market of comprehensive wiring yet.In modern new building, although design be reserved with corresponding hidden pipe, staple shaft, due to limited space, add the cables such as various power cord, telecommunication cable, optical cable intersection, repeatedly lay, increased difficulty and the architectural engineering expense of laying.Particularly the optical fiber in Dui Lao building is changed, and often needs traditional coaxial cable and existing optical fiber to carry out, because the structure of old-fashioned building and inconvenient laying-out thereof simultaneously.

Utility model content

The purpose of this utility model is intended to overcome deficiency of the prior art, by coaxial cable unit and butterfly leading in cable unit are combined, effectively save installing space, avoid secondary wiring, reduce operating expenses, can carry out optical fiber communication and radio signal transmission simultaneously.

Technical solution of the present utility model is: a kind of fiber-coaxial composite rope, comprise coaxial cable and optical cable, and described coaxial cable and optical cable are respectively after stranding and connect together.

In technique scheme, described coaxial cable comprises inner wire, insulating barrier, outer conductor layer, oversheath from the inside to the outside successively.

In technique scheme, described optical cable comprises optical fiber, non-metal reinforcement member, inner sheath, oversheath from the inside to the outside successively.

In technique scheme, between the oversheath of described coaxial cable and the oversheath of optical cable by hanging muscle and connecting together.

In technique scheme, the cross section of described inner sheath is butterfly, and described non-metal reinforcement member is symmetrically distributed in the both sides of optical fiber and is arranged in inner sheath.

In technique scheme, between described inner sheath and oversheath, be hollow.

The utility model compared with prior art has following feature and beneficial effect:

While using this product laying-out, a set of circuit can comprise coaxial cable and optical cable, effectively saves and lays time and pipeline space, reduces cable secondary and lays difficulty, reduces operating expenses;

Adopt low-smoke and halogen-free flame retardant polyolefin jacket; there is fire-retardant, low cigarette, Halogen, low toxicity, the harmful heavy metals such as not leaded, cadmium, the nonflammable and very high security feature of the little grade of smog injury during breaking out of fire; can not work the mischief to environment, meet the requirement of people to ecology and environmental protection simultaneously.

Accompanying drawing explanation

The utility model will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is the utility model example structure schematic diagram;

Fig. 2 is vertical (radially) sectional structure schematic diagram of the utility model embodiment;

Wherein: the 1st, inner wire, the 2nd, insulating barrier, the 3rd, outer conductor layer, the 4th, optical fiber, the 5th, non-metal reinforcement member, the 6th, inner sheath, the 7th, oversheath.

Embodiment

Below in conjunction with specific embodiments and the drawings, the utility model is further described.

As shown in Figure 1 and Figure 2, fiber-coaxial composite rope, main body comprises coaxial cable part and fiber optic cable part.Coaxial cable unit comprises inner wire 1 from inside to outside, insulating barrier 2 and outer conductor layer 3.Inner wire 1 is single circular copper wire or copper covered steel wire, and insulating barrier 2 is that physical blowing polyethylene is extruded in outside inner wire 1, and outer conductor layer 3 consists of aluminum-plastic composite membrane and tin-plating round copper wire braiding or aluminum-plastic composite membrane and aluminium alloy wire braiding, is coated on outside insulating barrier 2.Butterfly leading in cable unit comprises optical fiber 4 from inside to outside, non-metal reinforcement member 5 and inner sheath 6.Optical fiber 4 is arranged on the center of butterfly leading in cable inner sheath 6, and two non-metal reinforcement members 5 are arranged in butterfly leading in cable inner sheath 6 and symmetry is positioned at optical fiber 4 both sides, and the material of inner sheath 6 adopts low smoke halogen-free flame-retardant polyolefin plastics.Coaxial cable becomes splayed configuration with butterfly leading in cable, on its surface, extrudes oversheath 7, and the material of oversheath 7 adopts low smoke halogen-free flame-retardant polyolefin plastics.Position between inner sheath 6 and oversheath 7 is hollow.

The production process of above-mentioned fiber-coaxial composite rope is: vinyon is coated on to the outer formation insulating barrier 2 of inner wire 1 through physical blowing, the outer conductor layer 3 consisting of aluminum-plastic composite membrane and tin-plating round copper wire braiding or aluminum-plastic composite membrane and aluminium alloy wire braiding in insulating barrier 2 outer wrapping again, makes coaxial cable unit.Optical fiber 4 and non-metal reinforcement member 5 are passed to extruder head simultaneously, extrude one deck butterfly inner sheath 6, make butterfly leading in cable unit.The coaxial cable unit having made and butterfly leading in cable unit are passed to plastic extruding machine machine simultaneously, extrude oversheath 7, knot forms splayed configuration, and zero type at two is respectively coaxial cable unit and butterfly leading in cable unit, and centre connects by hanging muscle.
