High speed data cable
A high-speed data and cable technology, applied in the direction of double-stranded/four-stranded cable, etc., can solve the problem of easy position movement, different or random changes in the space occupied by the wire group, slow production speed, etc. It can improve the crosstalk problem and external signal interference problem, improve the crosstalk problem between groups, and be suitable for high-frequency and high-speed transmission.

Example Embodiment
[0030] Implementation example 1
[0031] Please see Figure 1 and Figure 2, a high-speed data cable, which contains four sets of insulated wire pairs (first insulated wire pair 1, second insulated wire pair 2, third insulated wire pair 3, third insulated wire pair 4 ), the sheath layer 5 covering all insulated wire pairs; it is characterized in that each group of insulated wire pairs includes two insulated wire cores twisted with each other and the two insulated wire cores are wrapped together and make two A covering layer 13 with a fixed insulated core position; each insulated core is composed of a conductor 10 in the inner layer, a shielding tape 11 covering the conductor, and an insulating layer 12 covering the shielding tape; shielding The tape is composed of a bonded inner layer 110, a shielding layer 111, and a bonded outer layer 112 that are sequentially bonded together. The thickness of the bonded inner layer is greater than the thickness of the bonded outer layer; the bon...
Example Embodiment
[0032] Implementation example 2
[0033] Please refer to Fig. 3 and refer to Figs. 1 and 2. A high-speed data cable is basically the same as Embodiment 1, except that the covering layer is plastic.
Example Embodiment
[0034] Implementation example 3
[0035] Please refer to Figure 4 and refer to Figure 3, a high-speed data cable, basically the same as the second embodiment, except that the axis of the insulated wire pair is perpendicular to each other, and the edge of the coating has a position indicating groove. On the one hand, the position indicating slot can provide a reference during production to ensure the accuracy of the placement of insulated wire pairs during production; on the other hand, it can be better stripped to make the removal of the insulation layer more convenient.
