Detailed Description

As shown in fig. 1, the invention discloses a metalized cross-shaped framework high-speed network cable, which comprises an insulating layer 1, a twisted pair 2, a metalized framework 3 and a shielding layer 4, wherein the twisted pair is composed of eight conductors, and each two conductors are paired and twisted with each other; the twisted pair is wrapped by the shielding layer 4, the insulating layer 1 is wrapped by the shielding layer 4, the metalized framework 3 is installed in the shielding layer 4, and each pair of wires is separated by the metalized framework 3.

The metallized framework is an insulating cross framework, and four pairs of wires of the twisted pair are respectively arranged in four grooves of the insulating cross framework; without the cruciform separation, one pair of wires in the cable may become trapped in a gap between two wires of another pair, and the spacing between the pairs is reduced, which exacerbates the crosstalk problem.

In the present invention, there are two implementation manners of the shielding layer 4, the first implementation manner: the shielding layer 4 comprises an electromagnetic shielding film and an aluminum foil layer, and the electromagnetic shielding film and the aluminum foil layer are wrapped on the twisted pair wires and distributed from inside to outside. The shielding layer 4 can prevent external electromagnetic interference, and ensures the stability of signal transmission.

The second implementation mode comprises the following steps: the shielding layer 4 is of a braided red copper structure, is non-magnetic, wear-resistant and good in sound insulation, and can effectively filter electron beams.

The metallized cross framework high-speed network cable comprises a super-five type network cable with the cable core diameter of 0.45 mm-0.51 mm.

The metallized cross framework high-speed network cable comprises a super six type network cable with a single-stranded bare copper wire of 23AWG (arrayed waveguide grating) and approximately equal to 0.573 millimeter, and also comprises a super six type network cable with a single-stranded bare copper wire of 24AWG and approximately equal to 0.511 millimeter in thickness.

The invention has the beneficial effects that: the high-speed mesh wire with the metalized cross-shaped framework adopts the metalized framework, reduces the crosstalk between wire pairs, and improves the frequency response of a cable with one or more signal wire twisted pairs.
