[background technology]

With the rapid development of Process of Urbanization Construction, existing optical fiber cable is mainly used for network, computer and radio and television The signal transmission of network, mostly all cannot be conductive, it is difficult to meet the use demand of communication terminal device while power supply.In order to enhance The use function of optical cable meets the needs of some application requirements supplies of electric power of the optical cable in transmission process, and also to save Laying resource is saved, has had photoelectric mixed cable at present.However photoelectric mixed cable common at present is mostly by light unit and gold Belong to lead unit layer and twist the layer-twisted type structure in a cable core, this structure using same cable core not only influences each list in cable The flexibility of member configuration and economy, and make troubles to the branch connection of light unit in transmission.

[utility model content]

The purpose of this utility model seeks to solve above-mentioned deficiency and provide a kind of partition type optoelectronic composite cable, can both expire Sufficient optical signal transmission can meet electric signal transmission again, can solve the demand connected up at this stage.

A kind of partition type optoelectronic composite cable is designed to achieve the above object, including two copper conductors 1, tight tube fiber 3, aramid fiber Fiber reinforcement core 4, block water band 5 and fire-retardant oversheath 6；1 periphery of every copper conductor is enclosed with insulating sheath 2, two Aramid fiber is equipped at a 2 adjacent segment of insulating sheath enhances core 4, the insulating sheath 2, the periphery of aramid fiber enhancing core 4 Be enclosed with the band 5 that blocks water, 5 periphery of band that blocks water is enclosed with fire-retardant oversheath 6, the insulating sheath 2 and block water band 5 it Between gap location be equipped with several tight tube fibers 3.

Optical fiber in the tight tube fiber 3 is the insensitive optical fiber of super shellfish bending loss.

For the tight tube fiber 3 using the hard-pressed bale material of Fypro, outer diameter is 500 μm.

The shape of triangle is made of high-strength flexible aramid fiber for the aramid fiber enhancing core 4.

The electric unit outer diameter that the copper conductor 1, insulating sheath 2 are formed is 3.0mm, wall thickness 0.5mm.

The fire-retardant oversheath 6 is formed by thermoplastic polyolefin elastomer material through extrusion molding.

The overall diameter dimensions of the optical cable are 7.5mm, and the wall thickness of the optical cable is 0.65mm.

The utility model compared with the existing technology, has the following advantages that：

(1) due to using the insensitive optical fiber of super shellfish bending loss inside tightly packaged fiber, so that the performance of incoming fiber optic It greatly improves, very positive effect is suffered to entire cable outer diameter, bending loss and anti-side pressure；

(2) tightly packaged fiber is by the way of the hard-pressed bale material of package Fypro, since material property has optical fiber Stronger protection makes optical fiber have the performances such as certain lateral pressure resistant, anti-aging, oil resistant, uvioresistant, such both to have reduced tightly The outer diameter cun of bag optical fiber, while also improve the performance requirement of optical fiber；

(3) non-metal reinforced layer of triangle is made of high-strength flexible aramid fiber, it not only can be in cable interior Isolated area is formed in space so that 2 electric units and 24 light units can be located at respective corresponding space and not interfere with each other, and have Effect prevents optical fiber from being squeezed in production and construction by electric unit and bringing additional optical transmission loss；And the setting of insulating sheath It is also prevented from optical fiber and is subject to electrostatic interference in transmission process；The cable configuration told can once remove can both construct light unit and Electric unit avoids the trouble that branch's wiring is removed in repetition；And the presence of electric conductor also allows optical cable to have certain stretch-proof Effect, allows entire optical cable to meet larger pulling force characteristic, and entire optical cable is allowed to have good tensile resistance and meet and is appointed The bending property in meaning direction；

(4) fire-retardant oversheath is formed by thermoplastic polyolefin elastomer material through extrusion molding, has centainly anti-aging, resistance to Oily, anti-ultraviolet performance, while ensure that entire optical cable meets single flame retardant property requirement, the entire outer diameter ruler of the optical cable Very little is about 7.5mm, and the wall thickness of the optical cable is about 0.65mm, and entire optical cable can more easily be used in computer room, interior etc. There is the occasion that photoelectricity lays special installation environment simultaneously.
