Example 1

Fig. 1 shows a schematic cross-sectional view of a cable body of the super-flexible data cable according to the present embodiment, and fig. 2 shows a schematic structure of a wrapping layer of the super-flexible data cable according to the present embodiment. As shown in fig. 1 and 2, the present embodiment provides an ultra-flexible data cable, the cable body of which includes an outer sheath 10, a total shielding layer 20, a first filling layer 30, and a cable core 40. The ultra-flexible data cable has high flexibility and bending resistance, so that the ultra-flexible data cable has longer service life, the intermittent disconnection problem caused by ageing of wires with excessive bending times is effectively reduced, and the use experience is optimized.

Specifically, the cable core 40, the total shielding layer 20 and the outer sheath 10 are sequentially arranged from inside to outside in a covering manner, and a first filling layer 30 is filled between the total shielding layer 20 and the cable core 40. The cable core 40 includes at least a data transmission line set 410; the total shielding layer 20 is coated on the periphery of the cable core 40, and is used for greatly increasing the anti-interference performance of the data transmission line group 410, reducing the leakage of transmission signals, and simultaneously effectively preventing the external electromagnetic environment from interfering with internal signals; the outer sheath 10 is made of PVC, PVDF, PE and other materials, so that the waterproof and wear-resistant performances of the ultra-flexible data cable are improved. In particular, to improve the bending resistance of the ultra-flexible data cable, the outer sheath 10 preferably uses a soft rubber material having a hardness conforming to the short a 50.

In detail, the total shielding layer 20 includes a shielding tape layer 21 directly covering the first filler layer 30 and the cable core 40, and a wrapping layer 22 surrounding the shielding tape layer 21. In this embodiment, the shielding tape layer 21 is an aluminum foil mylar tape for first layer interference shielding of the cable core 40. The wrap 22 surrounds the shield tape layer 21 to provide a second layer of interference shielding to the cable core 40. Wherein the wrapping layer 22 comprises a plurality of copper foil wires spirally wound on the shield tape layer 21. Compared with the tinned copper wires commonly adopted in the prior art, the copper foil wire has high flexibility and bending strength, and the material cost is equivalent, so that the ultra-flexible data cable improves bending resistance under the condition of relatively stable cost. Besides, compared with a conventional braiding structure, the wrapping structure can effectively reduce friction between copper foil wires when the cable is bent, and the flexibility and bending resistance of the ultra-flexible data cable are improved. In particular, a first drain wire 23 is further disposed between the shielding tape layer 21 and the wrapping layer 22, and is used for draining, so that the signal transmission performance of the cable core 40 is better ensured.

In the present embodiment, the first filler layer 30 filled between the total shielding layer 20 and the cable core 40 includes several ballistic filament kevlar, i.e. aramid fibers. The first filling layer 30 serves as a supporting material, so that the mechanical strength and tensile property of the ultra-flexible data cable are effectively improved, and the bending resistance is increased. Meanwhile, since the first filling layer 30 fills the gap between the data transmission line group 410 and the shielding tape layer 21, the first filling layer 30 also plays a role in protecting the cable core 40, reducing stress generated by external factors, and improving the service life of the ultra-flexible data cable.

In order to further improve the flexibility of the super-flexible data cable, the present embodiment also optimizes the structure of the cable core 40. As shown in fig. 1, the cable core 40 at least includes a data transmission line group 410, where the data transmission line group 410 includes a plurality of signal pairs, the signal pairs include a signal conductor 413, and a second filling layer 414 is further filled in a middle portion of the signal conductor 413. In this embodiment, the data transmission line group 410 includes a first signal pair 411 and a second signal pair 412, where the first signal pair 411 is a high-speed data transmission signal pair, and the second signal pair 412 is a low-speed data transmission signal pair. In this embodiment, the cable core 40 includes two first signal pairs 411 and one second signal pair 412, and each of the first signal pairs 411 and the second signal pairs 412 includes two signal conductors 413, where the signal conductors 413 are tin-plated copper wires. The middle of the signal conductor 413 is filled with a second filling layer 414. The second filler layer 414 is the same as the first filler layer 30 and is a filament-proof kevlar fiber for increasing the bending resistance of the signal conductor 413 in the cable core 40. It should be noted that, at both ends of the cable core 40, the second filling layer 414 cannot protrude out of the signal conductor 413, so as to avoid the adverse effect of the second filling layer 414 on the welding of the signal conductor 413.

In order to improve the overall bending resistance of the signal pair, the signal pair further comprises cotton wires 415, and the cotton wires 415 are in twisted connection with the signal conductors 413. Because cotton 415 has higher flexibility, the tensile resistance of the signal pair can be effectively increased, the bending resistance of the signal pair can be improved, and the service life of the signal pair can be prolonged. In this embodiment, the first signal pair 411 includes one cotton thread 415 and the second signal pair includes two cotton threads 415.

Further, at least one signal pair also includes a second drain line 416. In this embodiment, the first signal pair 411 includes a second drain wire 416, and the second drain wire 416, the cotton wire 415, and the two signal conductors 413 are twisted. In particular, the second drain wire 416 further includes copper foil wire and a third filler layer. In this embodiment, the second drain wire 416 includes four copper foil wires that surround the periphery of the third filler layer. The third filler layer is the same as the first filler layer 30 and is a ballistic kevlar fiber, i.e. an aramid fiber. Meanwhile, the structure of the first drain line 23 is the same as that of the second drain line 416. Therefore, the first drain wire 23 and the second drain wire 416 have good flexibility and bending resistance while having a disturbance reducing function, so that the quality of the ultra-flexible data cable is further ensured, and the service life is prolonged.

In summary, the present embodiment provides an ultra-flexible data cable, in which the wrapping layer 22 of the ultra-flexible data cable is a wrapping structure formed by wrapping copper foil wires with excellent flexibility, elasticity and bending strength, and the combination of the copper foil wires and the wrapping structure effectively increases the flexibility and bending resistance of the ultra-flexible data cable during bending. The wrapping structure reduces the mutual friction force between copper foil wires, delays the aging or damage progress of the ultra-soft data cable along with the increase of bending times, prolongs the service life, avoids the intermittent disconnection problem between the ultra-soft data cable and equipment, and optimizes the use experience.

On this basis, the first filling layer 30, the cotton wires 415, the second filling layer 414 and the third filling layer sequentially increase the flexibility and bending resistance of the whole super-flexible data cable, the whole signal pair, the signal conductor 413 and the drainage wire, so that the mechanical strength of each component of the super-flexible data cable is improved, the quality of the super-flexible data cable is further improved, and the super-flexible data cable has high bending fatigue strength.

It should be noted that the above is not a specific limitation on the type and number of signal pairs in the cable core 40, and those skilled in the relevant art may make corresponding modifications thereto.

Example 2

Referring to fig. 1 and 2, the ultra-flexible data cable of the present embodiment is the same as the ultra-flexible data cable of the first embodiment, and further includes a cable core 40 on the basis of the first embodiment, and the same points of the present embodiment as those of the first embodiment are referred to as the first embodiment, and the improvement will be further described.

As shown in fig. 1, the cable core 40 includes a power cord 420 in addition to the data transmission line set 410. In the present embodiment, the cable core 40 is provided with two power lines 420 for providing electric energy, and the two power lines 420 are respectively a positive line and a negative line of the power supply. In particular, the power line 420 includes a power conductor 421 and a fourth filler layer 422 disposed in the middle of the power conductor 421. The fourth packing layer 422 is identical to the first packing layer 30 and comprises a number of ballistic filament kevlar, i.e. aramid fibers. The fourth filling layer 422 increases the bending fatigue strength of the power line 420, and effectively reduces the risk of loss or even breakage of the power line 420 due to excessive bending times.

The first signal pair, the second signal pair and the outer layer of the power line are provided with inner jackets. The inner sheath is not identified in fig. 1. It is understood that the inner sheath is made of an insulating material such as TUR, PE, PVC or a shielding material, preferably a soft rubber material with high flexibility, so as to reduce mutual friction between different types of wire cores and avoid adverse effects on normal transmission performance of electric energy or data signals.

Example 3

Referring to fig. 1 and 2, the whole super-flexible data cable of the present embodiment is the same as the super-flexible data cable of the second embodiment, and the structure of the super-flexible data cable is further refined on the basis of the second embodiment, and the same points of the present embodiment and the second embodiment refer to the second embodiment, and the improvement points are further described below.

Fig. 3 is a schematic structural diagram of the super-flexible data cable according to the present embodiment. As shown in fig. 3, the super-flexible data cable includes a cable main body 100, and the cable main body 100 in this embodiment is the same as the cable main body 100 in the second embodiment, and both ends of the cable main body 100 are connected with the data input part 50 and the data output part 60, respectively. The data input part 50 and the data output part 60 are each provided with a connection terminal 70 for connection of different devices, so that data signals can be exchanged or transmitted between the different devices through the cable body 100. In the present embodiment, the connection terminal 70 is a USB interface. It will be appreciated that the connection terminal 70 may also be other interfaces for data signal transmission, and that those skilled in the relevant art may make alternatives and modifications thereto.

In this embodiment, the overall shape of the data input portion 50 is approximately conical to facilitate the user's grip. In particular, the data input portion 50 and the outer sheath 10 are integrally formed, and are formed of a material such as PVC, PVDF, PE. Preferably, the data input 50 is a soft rubber material having a hardness corresponding to that of the short a 50. Therefore, the data input portion 50 increases flexibility of the ultra-flexible data cable at the data input end, and effectively reduces risk of bending abrasion and even breakage of the ultra-flexible data cable during frequent plugging with the device.

Of course, in some embodiments, different kinds of materials or split connection may be used between the data input portion 50 and the outer sheath 10, and the structure of the data input portion 50 and the outer sheath 10 is not limited in particular.

The foregoing is merely illustrative and explanatory of the utility model as it is described in more detail and is not thereby to be construed as limiting the scope of the utility model. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the spirit of the utility model, and that these obvious alternatives fall within the scope of the utility model.
