Detailed Description

The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

Examples

As shown in fig. 1, a novel communication cable of S type shielding network, including cable tegillum 1, be equipped with a plurality of conductors 4 in the 1 intracavity of cable tegillum, the outer all cladding of a plurality of conductors 4 has insulating layer 3, still be equipped with wheat stretching strap shielding layer 2 between a plurality of conductors 4, a plurality of conductors 4 are stranded conductor or single conductor, wheat stretching strap shielding layer 2 is aluminium wheat stretching strap shielding layer or moulds wheat stretching strap shielding layer, insulating layer 3 is the polyolefin material, wheat stretching strap shielding layer 2, conductor 4 all sets up in S type mould with insulating layer 3, and wheat stretching strap shielding layer 2 is used for shielding two liang of a plurality of conductors 4, wheat stretching strap shielding layer 2 comprises aluminium foil paper, polyethylene glycol terephthalate.

Twisting core wires: the proper paying-off tension, the proper taking-up tension and the proper back twist rate are adopted, and the paying-off tension difference of the two core wires in the pair twisting process is controlled in a proper range, so that the uniform stress of the core wires in the pair twisting process and the subsequent process is ensured, the poor transmission performance is prevented, and the uniformity of the cable is ensured. A suitable twist-pair pitch in order to prevent interference between pairs.

Cabling: paying off the twisted core wire semi-finished product, and adopting electromagnetic tension control to ensure that the cable advances with stable tension and clamping force, and shielding blue, white, orange, white, green, white and brown, brown and white line pairs by using an aluminum foil mylar tape made of aluminum foil and polyethylene glycol terephthalate through an S mould made of special materials so as to better prevent the interference between the line pairs; during cabling, the core wire pair and the aluminum foil respectively enter the corresponding S-shaped die holes, the die holes limit the core wire pair and the aluminum foil, the core wire can be tightly wrapped by the aluminum foil with uniform tension step by step, the cabling take-up wire can be quite round and complete due to the stable and uniform rotation and pre-twisting of the take-up reel, the core wire is wrapped by 360 degrees by the shielding, and the aluminum foil wraps the core wire to form an S-shaped structure.

Sheath extrusion: the proper sheath thickness and the sheath extrusion mode are designed, the cable appearance is ensured to be round, the connector head is convenient to manufacture at the later stage, the flame retardance and the flexibility of a cable product are ensured by adopting a flame-retardant and flowable material, and the cable is ensured to move forwards with stable tension and clamping force by adopting active paying-off of a semi-finished product in the sheath extrusion process; the wire storage frame with the large wheel diameter ensures that the bending radius is suitable for transferring the wires in the moving process, so that the stress concentration cannot be caused to influence the wire diameter position and the transmission performance, the wire arrangement is neat, and the abnormal extrusion of the wire take-up shaft is prevented, so that the stable electrical performance of the wire take-up shaft is ensured.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the content of the present invention within the protection scope of the present invention.
