Description

Super six types of communication cables of no filling

Technical Field

The utility model relates to a super six types of communication cable technical field specifically are a super six types of communication cable of nothing packing.

Background

In the information society, communication cables are indispensable, the research and development project is based on the manufacturing technology of the existing communication cables of companies, and filling in the middle of the super six types of communication cables and shielding layers covering the outside of the cables are eliminated through design and process optimization.

In the conventional structure of the super-six types of communication cables, filling is added to the centers of the wire pairs during cabling, or shielding layers are coated outside the wire pairs (as shown in figures 2-3); the crosstalk between the wire pairs can meet the six-class standard, but the filling or the shielding layer coated outside the wire pairs is inconvenient for users to install and use.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a super six types of communication cables of no packing to solve the problem among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a super six types of communication cables of no filling, includes four line pairs, polyester area, four the line pair is located the polyester area, the polyester area outside is provided with the aluminium foil, the aluminium foil outside is provided with the outer quilt.

Preferably, the pair twist pitch of the wire pair is 3-5mm.

Preferably, the pair pitch of the wire pair is 4mm.

Preferably, the wire pair comprises a conductor and an insulating layer, and the insulating layer adopts a PP layer.

Preferably, the aluminum foil further comprises a ground wire, and the ground wire is positioned between the aluminum foil and the polyester tape.

Compared with the prior art, the beneficial effects of the utility model are that: the shielding layer filled in the middle of the super-six communication cables and externally coated by the wire pairs is eliminated, and the problem that the super-six communication cables are inconvenient to install and use by users in the prior art is solved on the basis of meeting the performance requirements of the super-six communication cables;

the pair-twisting pitch of the cable is reduced, the conventional pair-twisting pitch is about 10mm, and the conventional pair-twisting pitch is changed into 3-5mm at this time to improve the crosstalk performance; the core wire material is changed from PE to PP, so that the condition that the core wire is easy to flatten due to the reduction of the pair-twisting pitch is improved.
