[0003] As of June 2015, Intel released the third-generation Thunderbolt interface product (Thunderbolt 3). Although this Thunderbolt interface has been available for many years, there is currently no mature wire on the market that can completely match the Thunderbolt interface. The existing wires are always It has the disadvantage of poor shielding effect or not soft enough, so it needs to be improved

Embodiment 1
[0041] refer to figure 1 , is a special high-frequency flexible wire for lightning interface disclosed in the present invention, comprising: a wire body, a soft filler and an insulating outer layer 1 .
[0042] The main body of the wire is twisted by a super-fine coaxial cable 2, a pair of twisted wires 3, a core wire group 4, and a ground wire 5. There are 8 super-fine coaxial cables 2 (in other embodiments, it can also be 6, 7, 9 or 10), there is 1 pair of twisted wires 3, 6 ground wires 5 (in other embodiments, it can also be 4 or 5), and the core wire group 4 includes: 2 The first core wire 41, one second core wire 42 and three third core wires 43 are surrounded by the ultra-fine coaxial wire 2 in a circle, and the twisted pair 3 and the first core wire 41 are surrounded by the ultra-thin coaxial wire 2 Inside, the second core wire 42 and the third core wire 43 are sandwiched between adjacent ultra-fine coaxial wires 2; soft fillers are filled in the gaps in the wire body...
Embodiment 2
[0054] refer to figure 1 and Figure 4 , is a cable manufacturing method disclosed in the present invention, which is used to produce the high-frequency soft wire dedicated to the lightning interface as described in Embodiment 1. The cable manufacturing method includes:
[0055] S1, prepare ultra-fine coaxial cable 2, twisted wire 3, first core wire 41, second core wire 42, third core wire 43, ground wire 5 and soft filler;
[0056] S2, choose 8 ultra-fine coaxial cables 2 (in other embodiments, it can also be 6, 7, 9 or 10), 1 pair of twisted wires 3, 6 ground wires 5 (in other embodiments 4 or 5), 2 first core wires 41, 1 second core wire 42, 3 third core wires 43 and soft fillers are twisted together by a stranding machine to obtain a wire The main body, wherein the ultra-fine coaxial wire 2 is surrounded by a circle, the pair of twisted wires 3 and the first core wire 41 are surrounded by the ultra-fine coaxial wire 2 inside, and the second core wire 42 . The third core...

Abstract
The invention relates to a dedicated high-frequency soft wire for Thunderbolt and a preparation method of the wire. The wire comprises a wire body, soft fillers and an isolating insulation outer layer; the wire body is composed of 6-10 ultra-fine coaxial wires, one twisted wire, a core wire group and 4-6 ground wires that are twisted together, wherein the core wire group comprises two first core wires, one second core wire and three third core wires, the ultra-fine coaxial wires enclose the twisted wire and the first core wires in a cycle, and the second core wire and the third core wires aresandwiched between the adjacent ultra-fine coaxial wires; and the soft fillers fill gaps of the wire body that is wrapped by the isolating insulation outer layer. The wire containing multiple conductors apart from each other is designed to highly complex Thunderbolt, and has effects of round and firm structure, soft texture, difficult breakage, good shielding effect and stable signal transmission.
Description
technical field [0001] The invention relates to the technical field of wires and cables, in particular to a high-frequency soft wire material and a cable manufacturing method for a lightning interface. Background technique [0002] Thunderbolt is a high-speed I / O interface standard (code-named "Light Peak") developed by Intel in 2009. Its purpose is to serve as a general interface between computers and other devices, replacing and unifying a large number of performances on computers. Uneven expansion interfaces (such as SCSI, SATA, USB, FireWire, PCI Express, etc.). [0003] As of June 2015, Intel released the third-generation Thunderbolt interface product (Thunderbolt 3). Although this Thunderbolt interface has been available for many years, there is currently no mature wire on the market that can completely match the Thunderbolt interface. The existing wires are always It has the disadvantage of poor shielding effect or not soft enough, so it needs to be improved. Conte...
