Problems solved by technology

This structure will inevitably lead to problems of large attenuation and loop loss, because after the first and second wire cores 11, 12 are twisted, looseness will appear between the first and second wire cores 11, 12, and due to twisting The resulting voids are neither regular nor uniform, which affects the ability of the data cable to transmit signals, resulting in large attenuation

Embodiment 1

[0019] As shown in Figure 1, according to common sense in the industry, there are one pair, two pairs, four pairs, eight pairs, and sixteen pairs of wire pairs 1 of a data cable, or even hundreds of pairs. In view of this, one pair cannot be cited as an example in Fig. 1 of the present invention and the rest. Since the structures of the wire pairs 1 in the same data cable are completely identical, the applicant only chooses one for description. Each wire pair 1 includes first and second wire cores 11, 12, and the first wire core 11 includes a first conductor 111 and a first insulating layer 112 extruded outside the first conductor 111. Similarly, the second wire core 12 includes The second conductor 121 and the second insulating layer 122 extruded outside the second conductor 121 . The first and second wire cores 11 and 12 are adjacent to each other, more specifically, the first and second wire cores 11 and 12 are kept parallel to each other along the length direction in a st...

Embodiment 2

[0021] See Figure 2 and image 3 The pair of wire pairs 1 shown in the figure shows the situation that the second shielding layer 4 is wrapped around the two wire pairs 1 . If there are four pairs or six pairs or eight pairs or even 100 pairs of wire pairs 1, then the second shielding layer 4 wraps four pairs or six pairs or eight pairs of wire pairs or even hundreds of pairs of wire pairs 1, and the second shielding layer 4 The material of layer 4 is as described for the first shielding layer 3 . The effect of the second shielding layer 4 can block the gaps of the third shielding layer 5 located outside it, because the third shielding layer 5 is a structure of wire weaving, and there are many holes, so that the outer surface is uneven and affects The shielding effect, therefore, the second shielding layer 4 is used to improve the smoothness or smoothness so as to improve the shielding effect, and the outer sheath 2 is arranged outside the third shielding layer 5 . In this em...

Abstract

The invention relates to a high speed parallel symmetrical data cable, and belongs to the technical field of signal transmission cables. The data cable comprises at least a pair of line pairs and an outer sheath. Each pair of line pairs comprises a first conductor core and a second conductor core; the first core comprises a first conductor and a first insulating layer extruded and wrapped outside the first conductor; the second conductor core comprises a second conductor body and a second insulating layer extruded and wrapped outside the second conductor body; the first conductor core and the second conductor core are leaned mutually and parallel in the length direction; each line pair is externally wrapped with a first screening layer; and the outer sheath is positioned outside the first screening layer. The invention has the advantages that an uneven interval generated by pair twinning in the prior art is eliminated; the consistent distance between the first conductor core and the second conductor core is ensured; and the ideal characteristic impedance of the first conductor core and the second conductor core is ensured, so that the attenuation and the loop loss are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of signal transmission cables, in particular to a high-speed parallel symmetrical data cable. Background technique [0002] Data cables have been widely seen in literature, especially Chinese patent literature. For example, the utility model patent authorization announcement number CN2845120Y recommends a data cable with a conductive plastic shielding layer, and CN201051425Y introduces a data cable with an independent sub-shield. , CN2758948Y discloses an anti-jamming high-speed data cable, CN1183553C discloses a high-speed data cable with individually shielded twisted pairs, CN201081801Y discloses a star-quad data cable, CN101174495A discloses an armored data cable, CN2758946Y recommends A kind of shielding high-speed data cable and CN2609126Y have taught a kind of high-shielding outdoor data cable. In the above-mentioned documents, except for CN201081801Y and CN101174495A, they all focus on improving the ...
