Description

Technical Field

[0001] The utility model relates to the technical field of 3C digital accessories, in particular to a magnetic data cable. Background Art

[0002] When using electronic devices such as mobile phones and tablets, data cables are required for charging or data transmission with computers and other devices. Ordinary data cables are inconvenient for subsequent use because the cables are soft and easy to bend, and are easy to spread out or even get tangled. They also take up a lot of space, so they need to be stored when not charging or transmitting data. Some manufacturers have produced magnetic data cables, which can be positioned by magnets without being scattered by adding magnets and other structures to the data cables. However, the mutual attraction force between the magnets on the data cables is small, which is not enough to achieve automatic adsorption and storage. Therefore, the existing magnetic data cables still need to be manually wound before they can be stably magnetically adsorbed and stored. And when not manually wound, the magnets in different areas of the data cable may be attracted to each other, which has an adverse effect on the storage of the data cable. Therefore, compared with other storage methods (such as tying with a fixing belt), it does not actually achieve convenience for users. Utility Model Content

[0003] Therefore, in order to overcome at least some of the defects and shortcomings in the prior art, an embodiment of the utility model provides a magnetic data cable that can automatically reset after being stretched, completes rapid storage, and is more convenient to use.

[0009] In one embodiment, the first adsorption surface and the second adsorption surface are parallel to each other.

[0010] In one embodiment, the preset winding shape is a planar spiral line that is wound circle by circle from the center to the periphery.

In one embodiment, the pre-forming layer includes a magnetic material constituting the magnetic attraction portion; or the pre-forming layer is made of a soft rubber material having magnetic properties.

[0012] In one embodiment, the wire body further includes a magnetic material layer constituting the magnetic attraction portion, and the magnetic material layer is wrapped outside the pre-forming layer or the pre-forming layer is wrapped outside the magnetic material layer.

[0013] In one embodiment, the wire body further includes a protective layer, which is wrapped outside the pre-forming layer or is integrally formed with the pre-forming layer.

[0014] In one embodiment, the magnetic attraction parts are continuously distributed on the wire body.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solution in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0030] like Figure 1 The magnetic data line 100 provided by the embodiment of the utility model includes a line body 10 and a magnetic attraction portion 30. Figure 3As shown, the wire body 10 includes a wire core 11 and a pre-shaped layer 12 wrapped outside the wire core 11, and the pre-shaped layer 12 has elastic recovery ability. Figure 3 or Figure 4 ) is arranged on the line body 10.

[0031] Both ends of the wire body 10 are provided with data connectors 20 electrically connected to the wire core 11, for example. The data connector 20 can be a micro USB, type-C, mini USB or Lightning connector, etc., and is set according to the electronic device to be adapted.

[0032] The pre-molding layer 12 is, for example, soft rubber, such as TPE (Thermoplastic Elastomer).

[0033] In some embodiments, the wire body 10 may have a preset winding shape, and may automatically reset to the preset winding shape after being stretched through the elastic recovery ability of the predetermined forming layer 12, and at least part of the wire body 10 in the preset winding shape is magnetically attracted to each other through the magnetic attraction portion 30. Specifically, the preset winding shape of the wire body 10 may be, for example, a spiral winding, an S-shaped winding, or the like.

[0034] When the pre-forming layer 12 is made of a soft rubber material such as TPE, it can be formed into a long strip by extrusion molding or the like, and then wound according to a preset shape, and then baked to shape.

[0035] Since the predetermined shaping layer 12 wraps the wire core 11, the wire body 10 can automatically reset under the elastic restoring force of the predetermined shaping layer 12, thereby realizing rapid storage. When the wire body 10 has a preset winding shape, the entire wire body 10 will be wound along with the predetermined shaping layer 12 according to the preset winding shape. Figure 1 The figure shows the storage state of the magnetic data line 100. When the magnetic data line 100 is used, the line body 10 can be stretched to Figure 2 In the stretched state shown in FIG. 1 , after use, the stretching force applied to the wire body 10 is removed, and the wire body 10 can be automatically retracted to the elastic recovery capacity of the predetermined shaping layer 12. Figure 1 The storage state shown is automatically restored to the preset winding shape.

[0036] The magnetic attraction part 30 can be a magnet or magnetic powder coated on the surface of the wire 10, or a soft magnetic patch. The magnetic attraction part 30 can be set on the wire 10 by pasting, sleeve setting, etc. A plurality of magnetic attraction parts 30 can be set only corresponding to a part of the area of ​​the wire 10, so that several magnetic attraction parts 30 at specific positions under a preset winding shape can be adsorbed to each other to fix the wire 10 and prevent it from being scattered. Alternatively, the magnetic attraction parts 30 can be continuously distributed on the wire 10, so that any length position on the wire 10 has a magnetic attraction force, and any two contacting surfaces on the wire 10 under the preset winding shape can be magnetically attracted together to achieve more stable adsorption.

[0037] In some implementations, reference Figure 3 As shown, the pre-forming layer 12 includes a magnetic material constituting the magnetic attraction portion 30, or the pre-forming layer 12 is made of a soft rubber material having magnetism. The soft rubber material having magnetism is, for example, a mixture of TPE rubber material and magnetic powder. After the magnetic material such as magnetic powder is mixed into the TPE, it is extruded and formed, and then the pre-forming layer 12 is obtained by winding and shaping according to a preset winding shape. The magnetic portion 30 can be continuously distributed on the wire body 10, and the total thickness of the material wrapped outside the wire core 11 can also be reduced. In some embodiments, materials such as magnet sheets can also be mixed into the molding material of the pre-forming layer 12, so that the magnet sheets and the molding material are prepared and molded as one piece.

[0038] In some embodiments, the wire body 10 further includes a magnetic material layer constituting the magnetic attraction portion 30, and the magnetic material layer is wrapped outside the pre-forming layer 12 or the pre-forming layer 12 is wrapped outside the magnetic material layer. Figure 4 The structure in which the pre-forming layer 12 is wrapped outside the magnetic material layer is shown. In this case, the pre-forming layer 12 can protect the magnetic attraction portion 30. When the magnetic material layer is wrapped outside the pre-forming layer 12, the influence of the material thickness on the magnetic attraction effect can be reduced, and the magnetic attraction stability can be ensured.

[0039] The magnetic data cable 100 provided by the embodiment of the utility model can make the cable body 10 have a preset winding shape through the predetermined shaping layer 12 wrapped outside the cable core 11, and can automatically reset to the preset winding shape through the elastic recovery ability of the predetermined shaping layer after being stretched, and is fixed by the magnetic attraction part. Therefore, it can be automatically stored without manual winding, which is convenient for users to use and provides a better user experience.

[0040] In some embodiments, Figure 1 and Figure 2 As shown, the preset winding shape is a spring shape. In some embodiments, referring to Figure 3 and Figure 5 , the wire body 10 has a spring-like axial direction ( Figure 5The first adsorption surface 101 and the second adsorption surface 102 are opposite to each other in the direction of the midpoint dashed line), and the magnetic attraction portion 30 is arranged corresponding to at least one of the first adsorption surface 101 and the second adsorption surface 102. That is, the magnetic attraction portion 30 can be arranged corresponding to the first adsorption surface 101 alone, or the magnetic attraction portion 20 can be arranged corresponding to the second adsorption surface 102 alone, or the magnetic attraction portion 30 can be arranged on both the first adsorption surface 101 and the second adsorption surface 102. In the preset winding state, the wire body 10 can be regarded as being arranged according to Figure 5 In the orientation shown, the first adsorption surface 101 and the second adsorption surface 102 are respectively the upper and lower surfaces of each circle of the wire body 10, and the upper surface of each circle 10 is adjacent to the lower surface of the circle adjacent to it, that is, the first adsorption surface 101 and the second adsorption surface 102 of the adjacent circles are adjacent. When the magnetic attraction portion 30 is provided for the corresponding first adsorption surface 101 and the second adsorption surface 102, the first adsorption surface 101 and the second adsorption surface 102 adjacent to each other can be magnetically attracted. When the magnetic attraction portion 30 is provided only for the first adsorption surface 101 (or the second adsorption surface 102), each circle of the wire body 10 is magnetically connected through the magnetic attraction portion 30 on another circle of the wire body 10 adjacent to it.

[0041] The first adsorption surface 101 and the second adsorption surface 102 are both planes, that is, the line body 10 is Figure 3 More specifically, the first adsorption surface 101 and the second adsorption surface 102 are parallel to each other, and the above arrangement makes the adsorption area of ​​the wire body of the adjacent loops larger and the adsorption more stable.

[0042] Or, in other embodiments, referring to Figure 6 , the preset winding shape is a planar spiral line that is wound in circles from the center to the periphery. The wire body 10 has a first adsorption surface 101 and a second adsorption surface 102 that are opposite to each other in the radial direction (direction from the center to the periphery) of the preset winding shape, and the magnetic attraction portion 30 is arranged corresponding to at least one of the first adsorption surface 101 and the second adsorption surface 102. When the preset winding shape is a planar spiral line, the wire body 10 can be regarded as a plurality of circles stacked inside and outside, and the second adsorption surface 102 and the first adsorption surface 101 are respectively the inner and outer surfaces of each circle of the wire body 10, and the outer surface of each circle is adjacent to the inner surface of the adjacent outer circle, that is, the first adsorption surface 101 and the second adsorption surface 102 of the adjacent circles are adjacent. When the corresponding first adsorption surface 101 and the second adsorption surface 102 are both provided with the magnetic attraction portion 30, the first adsorption surface 101 and the second adsorption surface 102 that are adjacent to each other can be magnetically attracted to each other. When the magnetic attraction portion 30 is only provided corresponding to the first attraction surface 101 (or the second attraction surface 102 ), each coil of wire 10 is magnetically connected via the magnetic attraction portion 30 on another coil of wire 10 adjacent thereto.

[0043] The above two configurations of the first adsorption surface 101 and the second adsorption surface 102 of the wire body 10 can make the adjacent contact surfaces on the wire body 10 in the preset winding state contact more closely and the magnetic attraction more stable. The magnetization can be performed after the predetermined forming layer 12 is formed into a preset winding shape, so that the magnetic part 30 can be set corresponding to the first adsorption surface 101 and the second adsorption surface 102.

[0044] In some embodiments, the wire body 10 further includes a protective layer 13, such as Figure 3 As shown, the protective layer 13 is wrapped around the pre-forming layer 12 or is integrally formed with the pre-forming layer 12. The protective layer 13 can be, for example, a woven mesh layer formed by weaving a braided fabric, and the protective layer 13 can be used to enhance the toughness of the wire body 10 to prevent it from being broken.

[0045] The magnetic data cable 100 provided in the above embodiment of the utility model can automatically recover to a preset winding shape after being stretched through the elastic recovery ability of the predetermined shaping layer 12, and the shape is fixed through the magnetic attraction part 30, so that it can be quickly stored and used more conveniently.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
