Abstract
The utility model discloses a network and optical fiber combination cable. The network and optical fiber combination cable comprises fours sets of twisted-pair groups. Each set of twisted-pair group is formed by twisting two alloy conductors coated with insulating layers and wrapping a polyurethane thin film strip, a cross-shaped support is made from a thermoplastic elastomer through the extrusion moulding process, the fours sets of twisted-pair groups are distributed in each region of the support, an optical fiber bundle sleeved with a loose sleeve is arranged at the center of the support, a strengthening element which is formed by twisting polyester silk is arranged at the center of the optical fiber bundle, the outside of the support and the outside of the fours sets of twisted-pair groups are coated with a shielding layer, a flame retardant layer and a sheath layer successively. According to the utility model, the advantage of reasonable structural design is realized, the fours sets of twisted-pair groups are divided through the support, and the optical fiber bundle is further arranged at the same time, so the synchronous transmission of optical signals and the electrical energy is realized, and advantages of stable signal transmission, less outside influence and less own influence are realized.
Description
Technical field:
The utility model relates to cable, relates in particular to a kind of network and optical fiber combination cable.
Background technology:
Four pairs of traditional unit networks line structure compactedness are poor, and transmission of information is single, and the signal transmission is subjected to the external interference effect, and signal transmission quality is low.
In order to guarantee up to 200MHZ data transfer performance, alloy conductor adopts the solid mild alloy conductor of high conductivity, insulating barrier adopts the polyolefine material of low dielectric constant, two of even structure is thoroughly done away with the edge single line twist together formation pair twist group, gathering for four groups becomes whole piece data-signal transmission link again.
The utility model content:
In order to remedy the defective of prior art problem, the purpose of this utility model provides a kind of network and optical fiber combination cable, reasonable in design, and signal transmission quality is good, is subjected to extraneous impact with self very little.
The technical solution of the utility model is as follows:
Network and optical fiber combination cable, it is characterized in that: comprise four groups of pair twist groups, every group of mutually stranded and wrapped polyurethane film band formation of alloy conductor that the pair twist group adopts two wrap insulate layers, there is thermoplastic elastomer (TPE) to be extruded into criss-cross bracing frame, four groups of pair twist groups are distributed in the regional of bracing frame, the bracing frame center is provided with the fiber bundle of the loose sleeve pipe of suit, the fiber bundle center is provided with the reinforcement of the stranded bunchy of dacron thread, and bracing frame and four groups of pair twist groups are enclosed with successively outward and are enclosed with successively screen, flame retardant coating, restrictive coating.
Described network and optical fiber combination cable is characterized in that: described screen adopts the wrapped formation of copper strips, and the wrapped rate of putting up is not less than 65%.
The utility model has the advantages that:
The utility model reasonable in design by bracing frame is cut open four groups of pair twist components, is set up fiber bundle simultaneously, transmits when realizing light signal and electric energy, and stable signal transmission is subjected to the external world and self affects little.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Network and optical fiber combination cable, comprise four groups of pair twist groups, every group of pair twist group adopts the alloy conductor 1 mutually stranded and wrapped polyurethane film band 3 of two wrap insulate layers 2 to consist of, there is thermoplastic elastomer (TPE) to be extruded into criss-cross bracing frame 4, four groups of pair twist groups are distributed in the regional of bracing frame 4, bracing frame 4 centers are provided with the fiber bundle 6 of the loose sleeve pipe 5 of suit, fiber bundle 6 centers are provided with the reinforcement 7 of the stranded bunchy of dacron thread, and bracing frame 4 and four groups of pair twist groups are enclosed with successively outward and are enclosed with successively screen 8, flame retardant coating 9, restrictive coating 10.
