Problems solved by technology

[0004] 1. Poor shielding performance, usually only aluminum foil shielding, or even no shielding layer, the signal transmission is easy to leak during use, the anti-interference ability is poor, and the influence of the surrounding environment increases sharply;
[0005] 2. The hardness of the cable is relatively high, it is not easy to bend, and the service life is short;

Embodiment 1

[0037] like figure 1 As shown, the flexible data line includes a plurality of conductors, and the plurality of conductors are annealed copper wires, and each conductor in the plurality of conductors is provided with an insulating layer 3, and the insulating layer 3 is FEP; the ground wire 4; filling 5, the filling 5 is aramid yarn; shielding layer 6, the shielding layer 6 internally wraps the plurality of conductors, ground wires 4 and filling 5; braiding layer 7, the braiding layer 7 is wrapped in the shielding Outside the layer 6, the braided layer 7 includes copper wires and nylon wires, the diameter of the copper wires is 0.04-0.10mm, the filling denier of the nylon wires is 150D-500D, and the weaving density of the braided layer is greater than 95%; and The outer drape 8 is wrapped on the outside of the braided layer 7 , the outer drape 8 is TPE, and the Shore hardness of the TPE is 72A.

[0038] The shielding effect is ensured by using the shielding layer 6 and the brai...

Embodiment 2

[0050] On the basis of the above embodiment, it also includes a cotton braided layer 9 wrapped around the outside of the outer drape 8; the cotton braided layer 9 is a double-layer mixed twisted polyester yarn layer. The outer diameter of the cotton braided layer 9 is 3.2mm. The denier of polyester yarn is 100-300D.

[0051] The cable cotton braid is made of high-quality wear-resistant twisted polyester yarn. The workmanship is double braided, a technique used in rope making that gives the cable great strength and extra elasticity. This makes the cable more wear-resistant, more flexible, lighter and less susceptible to damage from the external environment. Mixing is conducive to the selection of color types, and the scheme is more diverse.

[0052] The flexible data cable provided by the present invention has the following advantages:

[0053] 1. The anti-fatigue and anti-stress ability of the cable is significantly improved, and the service life is increased; using R=5mm,...

Abstract

The invention relates to a data line and particularly relates to a flexible data line. The flexible data line includes multiple conductors, a ground wire, a filler, a shielding layer, a braiding layer and an outer sheath, wherein the multiple conductors are soft copper wires, each of the multiple conductors is provided with an insulation layer, the multiple conductors, the ground wire and the filler are externally wrapped in the shielding layer, the shielding layer is externally wrapped in the braiding layer, and the braiding layer is externally wrapped in the outer sheath. The flexible data line has advantages of good shielding effect, easy bending, small volume, convenient carrying and large tension strength.

Description

technical field [0001] The invention relates to a data line, especially a flexible data line. Background technique [0002] In today's era of diversified technology, with the popularization and development of entertainment equipment and peripheral products such as smartphones, tablet computers, and Bluetooth audio, USB cables have also undergone changes from version 1.1 to version 4.0. The requirements of the wire are becoming more and more diversified, the transmission frequency is getting higher and higher; the transmission rate is getting faster and faster; the size of the wire is getting smaller and smaller; the carrying capacity of the wire is getting bigger and bigger. Among them, USB2.0 wire is the largest consumer electronic wire in the current market base, and its branches are also numerous, such as USB A-Ligthing structure, USB A-Type-C structure, USB C-Lighting structure, etc., which are affected by production methods and even life. With the change of the way, co...
