Problems solved by technology

[0004] The chemical foaming method is mainly realized by an extruder. Due to the small size of the mold, the sensitivity to temperature control, the ratio of the foaming material, and the quality of the foaming material batch, the extruder used for chemical foaming is in the process of forming. The electrical uniformity (foaming stability) of the foamed insulating layer is difficult to guarantee
Although the physical foaming method has advantages in obtaining better foaming stability, however, physical foaming is relatively high in terms of equipment cost and process cost, and the production efficiency is not ideal
[0005] In view of this, how to obtain high-quality data cables under the premise of pursuing economy and overcome the problems caused by the difficulty in ensuring the stability of the covering insulation layer of data cables during manufacturing is the original intention of this patent

Embodiment 1

[0037] A structural diagram of a high-frequency data cable that is beneficial to manufacture in this embodiment is shown in Figure 1 to Figure 3 . The high-frequency data line includes four pairs of circumferentially distributed sub-cables 10 and sub-cables positioned at the center of the circumference to form 5 sets of signal lines, and electronic wires 24 and ground wires 23 formed by other four sub-cables; The metal foil shielding layer 20 , the metal shielding layer 21 , and the sheath 22 cover, wherein the ground wire 23 is located between the metal foil shielding layer 20 and the metal shielding layer 21 .

[0038] The set of cables 10 in this embodiment includes two cores, which are composed of a conductor 11 contained in the basic components and an outer conductor coating 12. Because the conductor coating 12 is not a key element of this patent, it is not included. I will repeat. The core and the foamed insulator 13 implemented according to the spirit of the inventio...

Embodiment 2

[0042] A structural diagram of a high-frequency data cable that is beneficial to manufacture in this embodiment is shown in Figure 4 to Figure 6 .

[0043] Compared with Embodiment 1, the main difference of this implementation is that the foamed insulator 13 of this embodiment covers a core, and the implementation of the coating described in the spirit of the invention of this patent corresponds to the case of an independent core.

Abstract

The invention discloses a high-frequency data cable being convenient to make and a making method thereof. The high-frequency data cable is formed by a plurality of sub cables; the sub cables include conductor core parts or core parts with conductors inside and insulators coating the core parts; and the insulators coat the core parts by non-foamed adhesion layers, wherein the insulators are foamedlayers. With the method provided by the invention, the corresponding high-frequency data cable is easy to make; and the cable has the high-stability electrical characteristics in the length direction,so that the excellent inherent frequency characteristics are obtained.

Description

technical field [0001] This patent relates to the field of data cables, focusing on high-frequency data cables, and can control the data exchange requirements of transmission bandwidth measured in Gbit / s, especially the data exchange requirements of transmission bandwidth measured in tens or even hundreds of Gbit / s. It relates to a high-frequency data cable which is favorable for manufacture and a manufacture method thereof. Background technique [0002] High-definition video, especially ultra-high-definition video represented by 4K and above, is entering thousands of households. During the popularization period of the new wave of high-definition video, the data lines for transmitting high-definition video also put forward correspondingly higher requirements. The data bandwidth of incoming high-definition data cables has grown to more than 30Git / s. For example, the transmission bandwidth of DisplayPort 1.4 can reach 32Gbit / s, the transmission bandwidth of Thunderbolt 3 can ...
