Description

[Technical Field]

[0001] The present invention relates to the field of data cable technology, and more particularly to magnetically retractable data cables. [Background technology]

[0002] Data cables are commonly used power-carrying components in electronic equipment. Data cables are long and are generally wrapped around one another when carried. Therefore, when using the device, it is necessary to untie the cable, which is very troublesome, and the appearance is unattractive, messy, and takes up space.

[0003] To facilitate the storage of data cables, magnetically suctioned retractable data cables have been developed. Patent Document 1 discloses a magnetically storable data cable, the cable body of which includes, from the inside to the outside, a wire core, an insulating layer, a magnetically suction material layer, an aluminum foil layer, and an outer braided layer. This structure uses a magnetic attraction material layer to achieve adhesion by wrapping, and an aluminum foil layer to prevent the magnetic powder from falling off. However, the aluminum foil layer is relatively hard and tends to take shape, making it difficult to wind the data cable because the aluminum foil layer itself is relatively hard, and even after winding, the cable body is fixed in its curved shape by the aluminum foil layer. Therefore, when the data cable is unfolded, a partial bend remains in the cable body, and once the cable is straightened, it becomes difficult to rewind it, which causes inconvenience in use. Furthermore, the braided layer is usually made thick to protect the magnetic attraction material layer and the internal wire core, but the braided layer lacks elasticity, making the magnetic attraction winding data cable body stiffer, making it difficult to wind and unwind during use, and also making it uncomfortable to touch. In addition, the surface has a mesh pattern, which makes it easy for dust to accumulate, affecting the aesthetics and cleanliness of the product after prolonged use. In response to the above problems, the present invention provides an innovative design for the data cable. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] CN221428166U specification Summary of the Invention [Problem to be solved by the invention]

[0005] The prior art has the drawback that the aluminum foil layer is hard and easily fixed in shape, and the thick, inelastic braided layer makes it difficult to wind and unfold, makes it uncomfortable to the touch, and furthermore, dust easily accumulates in the mesh, making it difficult to look good and clean. [Means for solving the problem]

[0006] This invention relates to a magnetically retractable data cable that uses cotton paper between the magnetically attractive intermediate coating layer and the braided layer to provide insulation, and a transparent silicone outer jacket on the outside of the braided layer. This makes the magnetically attractive wire more flexible, improving the feel when wound and unwrapped, and also provides a protective barrier around the braided layer, improving the cable's visual aesthetics.

[0007] The magnetically retractable data cable of the present invention comprises a retractable magnetically attracted wire and data connectors installed on both ends of the magnetically attracted wire. The wire body has a wire core and an insulating layer surrounding the wire core, the outside of the insulating layer is covered with a magnetically attracting intermediate covering layer, a braided layer is provided on the outside of the magnetically attracting intermediate covering layer, and cotton paper is provided between the magnetically attracting intermediate covering layer and the braided layer. The outer braided layer is covered with a clear silicone outer covering.

[0008] Compared with the conventional technology, the present invention has the following advantages: In this invention, cotton paper is placed between the magnetically attractive intermediate coating layer and the braided layer to provide insulation, and a transparent silicone outer coating is placed on the outside of the braided layer. On the one hand, this makes the magnetically attractive wire more flexible, improving the feel when wound up and unwrapped. On the other hand, the transparent silicone outer coating hermetically covers and protects the braided layer, and the braided pattern of the inner layer can be seen through the silicone outer coating, further improving the visual aesthetic. [Brief explanation of the drawings]

[0009] [Figure 1] 1 is a schematic diagram of a magnetically retractable data cable according to an embodiment of the present invention; [Figure 2] 1 is a cross-sectional view of a magnetically retractable data cable according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention will be described in detail below in combination with drawings and specific embodiments. As shown in FIGS. 1 and 2, the magnetically retractable data cable 1 of the present invention comprises a retractable magnetically attracted line body 10 and data connectors 20 installed on both ends of the magnetically attracted line body 10. The wire body 10 has a wire core 11 and an insulating layer 12 that covers the outside of the wire core 11. The outside of the insulating layer 12 is covered with a magnetically attracting intermediate coating layer 13 , and the magnetically attracting intermediate coating layer 13 is filled so as to fill the gaps between the insulating layers 12 of the respective wire cores 11 . A braided layer 15 is provided on the outside of the magnetically attractive intermediate coating layer 13, and cotton paper 14 is provided between the magnetically attractive intermediate coating layer 13 and the braided layer 15 to prevent magnetic particles from falling off. The cotton paper 14 has flexibility and can prevent the wire 10 from curling and becoming deformed.

[0011] The outside of the braided layer 15 is covered with a transparent silicone outer covering 16 . The transparent silicone jacket 16 is a transparent silicone jacket mixed with dyes of different colors, and the transparent silicone jacket 16 exhibits different transparent colors such as purple transparent, blue transparent, etc., thereby making the data cable more distinctive. The transparent silicone outer cover 16 hermetically encases the braided layer 15, thereby protecting the braided layer 15 and realizing dust and dirt resistance, and further allowing the braided pattern of the inner layer to be seen through the silicone outer cover, thereby realizing visual aesthetics.

[0012] The thickness of the transparent silicone jacket 16 is much greater than the thickness of the braided layer 15, and the braided layer 15 does not affect the flexibility of the silicone, so the feel of the wire body 10 of the entire data cable is not affected. The transparent silicone jacket 16 hermetically encases the braided layer 15, making the data cable body 10 more flexible, more comfortable to the touch, and easier to unfold the wound data cable.

[0013] In one embodiment, the magnetically attractive intermediate coating layer 13 is an extruded mixture of plastic and magnetic powder. In another embodiment, the magnetically attracting intermediate coating layer 13 may be an extruded mixture of magnetically attracting particles and a silicone material.

[0014] To sum up, the key design points of this invention are as follows: In this invention, cotton paper is placed between the magnetically attractive intermediate coating layer and the braided layer to provide insulation, and a transparent silicone outer coating is placed on the outside of the braided layer. This makes the magnetically attractive wire more flexible, improving the feel when wound up and unwrapped. On the other hand, the transparent silicone outer coating hermetically covers and protects the braided layer, and the braided pattern of the inner layer can be seen through the silicone outer coating, achieving a visually aesthetic look.

[0015] The drawings of the embodiments disclosed in the present invention only show the structures according to the disclosed embodiments, and other structures can refer to the general design. Unless contradictory, the same and different embodiments of the present invention may be combined with each other.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the invention shall fall within the protection scope of the invention. [Explanation of symbols]
