Abstract

The utility model discloses data network cable, which comprises four twisted-pair groups. Two alloy conductors coated with insulation layers are mutually twisted and are wrapped with a layer of polyurethane thin film tape to form each twisted-pair group. A frame is provided. The frame is cross-shaped through extrusion of thermoplastic elastomer. The four twisted-pair groups are distributed in each section of the frame to form a cable core. An inner shielding layer, a fireproof layer, an outer shielding layer and a sheath layer are sequentially coated outside the cable core. The data network cable is reasonable in structure and design; and through separating the four twisted-pair groups by the frame and simultaneously arranging two layers of shielding outside the cable core, the signal transmission of the cable can be stable and little affected by the outside and the cable itself, thereby improving the quality of the signal transmission.

Description

A kind of data network cables

Technical field:

The utility model relates to cable, relates in particular to a kind of data network cables.

Background technology:

Four pairs of traditional unit networks line structure compactedness are poor, and the signal transmission receives the external interference effect, and signal transmission quality is low.

In order to guarantee transmission performance up to the 200MHZ data; Alloy conductor adopts the solid mild alloy conductor of high conductivity; Insulating barrier adopts the polyolefine material of low dielectric constant; Two insulated single lines of even structure are twisted together formation pair twist group, and gathering for four groups becomes whole piece data link again.

The utility model content:

The purpose of the utility model provides a kind of data network cables, reasonable in design, and signal transmission quality is good, receives extraneous influence with self very little.

The technical scheme of the utility model is following:

Data network cables; It is characterized in that: comprise four groups of pair twist groups; Every group of each other stranded and wrapped one deck polyurethane film band formation of alloy conductor that the pair twist group adopts two wrap insulate layers includes skeleton, and skeleton is that thermoplastic elastomer (TPE) is extruded into cross; Four groups of pair twist groups are distributed in each zone formation cable core of skeleton, and cable core is enclosed with successively outward and is enclosed with internal shield, fireprotection layer, outer shielding layer, restrictive coating successively.

Described data network cables is characterized in that: described internal shield copper wire braiding constitutes, and count is not less than 88%.

Described data network cables is characterized in that: described outer shielding layer adopts the wrapped formation of copper strips, and the wrapped rate of putting up is not less than 45%.

The utility model has the advantages that:

The utility model reasonable in design through skeleton is severed four groups of pair twist components, is provided with double layer screen simultaneously outside cable core, make that the cable signal transmission is stable, receive extraneous with self influence little, thereby improved signal transmission quality.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Embodiment:

Referring to Fig. 1:

Data network cables; Comprise four groups of pair twist groups; Every group of pair twist group adopts the wrapped one deck polyurethane film band 3 in alloy conductor 1 mutual stranded back of two wrap insulate layers 2 to constitute, and includes skeleton 4, and skeleton 4 is extruded into cross for thermoplastic elastomer (TPE); Four groups of pair twist groups are distributed in each zone formation cable core of skeleton 4, and cable core is enclosed with successively outward and is enclosed with internal shield 5, fireprotection layer 6, outer shielding layer 7, restrictive coating 8 successively.

The braiding of internal shield 5 copper wires constitutes, and count is not less than 88%.

Outer shielding layer 7 adopts the wrapped formation of copper strips, and the wrapped rate of putting up is not less than 45%.
