Whether at home, in the office, or traveling, transmission cables are used very frequently. Therefore, the storage and user experience of transmission cables have gradually become issues of concern.

[0003] Traditional magnetic transmission lines suffer from poor magnetic attraction due to their structural design, making them difficult to store. Utility Model Content

[0004] This application provides a magnetic transmission line that enhances the magnetic attraction effect of the magnetic transmission line and makes it easier to store.

[0005] This application provides a magnetically attached transmission line, comprising: At least one wire core; A first filler layer is disposed around at least one of the wire cores; The second filling layer includes a first filling portion and a second filling portion, wherein the first filling portion and the second filling portion are disposed on both sides of the first filling layer along a first direction; An outer protective layer is disposed around the first filling layer and the second filling layer; In this configuration, one of the first filling layer and the second filling layer is a magnetic layer, and the other is a flexible filling layer. The cross-section of the magnetic transmission line has a width greater than its width along the first direction than its width along the second direction, and the first direction is perpendicular to the second direction.

[0006] In some embodiments, the second filling layer further includes a third filling portion, which is connected to the first filling portion and the second filling portion; The first filling layer is disposed around the third filling portion, and the third filling portion is disposed around at least one of the wire cores.

[0007] In some embodiments, the first filling portion, the third filling portion, and the second filling portion are integrally formed.

[0008] In some embodiments, the outer sheath has a first end face and a second end face opposite each other along the second direction, both the first end face and the second end face being planar, and the first end face being parallel to the second end face.

[0009] In some embodiments, the outer sheath has a third end face and a fourth end face opposite to each other along the first direction, and the first end face, the third end face, the second end face, and the fourth end face are connected in sequence; Both the third end face and the fourth end face are planar, and the third end face is parallel to the fourth end face; or, both the third end face and the fourth end face are arc surfaces.

[0010] In some embodiments, the wire cores are multiple; All of the said wire cores are located inside the first filler layer; or At least one of the wire cores is located inside the first filler layer, and at least one of the wire cores is located inside the first filler portion; or At least one of the wire cores is located inside the first filler layer, and at least one of the wire cores is located inside the second filler portion; or At least one of the wire cores is located inside the first filling layer, at least one of the wire cores is located inside the first filling portion, and at least one of the wire cores is located inside the second filling portion.

[0011] In some embodiments, the core located inside the first filler layer comprises a plurality of metal wires electrically insulated from each other.

[0012] In some embodiments, the wire core further includes a metal shielding layer disposed around the periphery of the plurality of metal wires.

[0015] In this embodiment of the magnetic transmission line, the width of the cross-section along the first direction is greater than the width along the second direction. Therefore, the first filling portion, the first filling layer, and the second filling portion can be arranged sequentially, providing ample space for the placement of the magnetic layer. For example, when the first filling layer is a magnetic layer, its width can be set larger to enhance magnetic performance and thus improve the magnetic effect of the magnetic transmission line. When the second filling layer is a magnetic layer, it can be distributed on both sides of the magnetic transmission line, meaning the magnetic layer is divided into a first filling portion and a second filling portion. By placing magnetic layers on both sides of the transmission line, the overall magnetic performance of the magnetic layers can be enhanced, thereby improving the magnetic effect of the magnetic transmission line. Therefore, the magnetic transmission line of this embodiment enhances the magnetic effect and makes the magnetic transmission line easy to store. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] This application provides a magnetically attached transmission cable. This magnetically attached transmission cable can be a data cable and / or a charging cable, used for data transmission and / or charging of electronic devices. Furthermore, this magnetically attached transmission cable has a magnetic attraction function; when the cable is wound, the parts that are in contact with each other are attracted to each other magnetically, making it easy to store.

[0027] refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the first cross-sectional structure of the magnetic transmission line 100 according to an embodiment of this application. Figure 2 This is a schematic diagram of a second cross-sectional structure of the magnetic transmission line 100 according to an embodiment of this application. The magnetic transmission line 100 includes a core 10, a first filling layer 20, a second filling layer 30, and an outer sheath 40.

[0028] In this configuration, there are one or more wire cores 10, meaning at least one. When there are multiple wire cores 10, they are spaced apart. For example... Figure 1 and Figure 2 As shown, the magnetic transmission line 100 may include three spaced-apart cores 10. The cores 10 are used to transmit data or current, realizing data transmission and / or charging functions. Each core 10 includes at least one metal wire, which may be, for example, a copper wire. In practical applications, the metal wire can be formed from a single metal wire or from multiple metal wires wound together. A metal wire formed from multiple wound metal wires can improve data transmission and current transmission capabilities.

[0029] A first filling layer 20 is disposed around at least one wire core 10. A second filling layer 30 includes a first filling portion 31 and a second filling portion 32. The first filling portion 31 and the second filling portion 32 are disposed on both sides of the first filling layer 20 along a first direction X. One of the first filling layer 20 and the second filling layer 30 is a magnetic layer, and the other is a flexible filling layer. In one example, such as... Figure 1 As shown, the first filling layer 20 can be a magnetic layer, and the second filling layer 30 can be a flexible filling layer. In another example, such as Figure 2 As shown, the first filling layer 20 can be a flexible filling layer, and the second filling layer 30 can be a magnetic layer.

[0030] The magnetic layer is formed of a magnetic material, which enables the magnetic transmission line 100 to have a magnetic function. In some embodiments, the magnetic material may also have flame-retardant properties, so the magnetic layer can also be understood as a flame-retardant magnetic layer, which can improve the safety of the magnetic transmission line 100.

[0031] The flexible filler layer can be formed from a highly flexible material such as TPE (thermoplastic elastomer, also known as synthetic rubber), giving the magnetic transmission line 100 high flexibility. It requires no shaping, does not spring back during use, and offers superior practicality, while also extending the lifespan of the magnetic transmission line 100. In some embodiments, the flexible filler layer also possesses flame-retardant properties, further enhancing the safety of the magnetic transmission line 100.

[0032] In practical applications, the magnetic layer and the flexible filler layer can be extruded in one step using a specially designed one-piece extrusion die, resulting in better adhesion between the two materials. No secondary extrusion is required during production, making the production process more energy-efficient and environmentally friendly.

[0033] In practical applications, when there are multiple cores 10, based on the structural design of the first filling layer 20, the first filling part 31, and the second filling part 32 described above, the multiple cores 10 can have various arrangement methods. (See also...) Figures 1 to 5 , Figure 3 This is a schematic diagram of a third cross-sectional structure of the magnetically attracted transmission line 100 according to an embodiment of this application. Figure 4 This is a schematic diagram of the fourth cross-sectional structure of the magnetically attracted transmission line 100 according to an embodiment of this application. Figure 5 This is a schematic diagram of the fifth cross-sectional structure of the magnetically attracted transmission line 100 according to an embodiment of this application.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, it can be configured such that at least one wire core 10 is located inside the first filling layer 20, at least one wire core 10 is located inside the first filling portion 31, and at least one wire core 10 is located inside the second filling portion 32.

[0035] In some embodiments, such as Figure 3 As shown, it can be configured such that multiple wire cores 10 are all located inside the first filler layer 20.

[0036] In some embodiments, such as Figure 4 As shown, it can be configured such that at least one wire core 10 is located inside the first filling layer 20, and at least one wire core 10 is located inside the first filling portion 31.

[0037] In some embodiments, such as Figure 5 As shown, it can be configured such that at least one wire core 10 is located inside the first filling layer 20, and at least one wire core 10 is located inside the second filling portion 32.

[0038] Continue to refer to Figure 2In some embodiments, the core 10 located inside the first filler layer 20 includes a plurality of metal wires 11, which are electrically insulated from each other. For example, an insulating layer may be wrapped around each metal wire, or insulating material may be filled between adjacent metal wires to make the plurality of metal wires electrically insulated from each other.

[0039] In some embodiments, the conductor 10 further includes a metal shielding layer, for example... Figure 2 The metal shielding layer 12 is shown. The metal shielding layer 12 is disposed around the periphery of the plurality of metal wires 11. When there are multiple wire cores 10, a metal shielding layer can be disposed around the metal wire of each wire core 10. Specifically, when a wire core 10 includes a single metal wire, the metal shielding layer can be disposed around that single metal wire; when a wire core 10 includes multiple metal wires, the metal shielding layer can be disposed around all of the metal wires, for example... Figure 2 The metal shielding layer 12 shown is disposed around the three metal wires 11. Understandably, in practical applications, the metal wires and the metal shielding layer are electrically insulated. In one example, the metal shielding layer may be, for example, a shielding layer formed of aluminum foil. The metal shielding layer can be used to shield external electromagnetic signals and reduce external electromagnetic interference experienced by the metal wires when transmitting data or current.

[0040] Continue to refer to Figure 1 The outer sheath 40 is disposed around the first filling layer 20 and the second filling layer 30, enclosing the wire core 10, the first filling layer 20, and the second filling layer 30. The outer sheath 40 provides protection for the magnetic transmission line 100, preventing damage caused by scratches, bumps, etc. during use. In some embodiments, the outer sheath 40 also has flame-retardant properties, which can improve the safety of the magnetic transmission line 100 in use.

[0041] In practical applications, the outer sheath 40 can be a braided sheath, or a mesh sheath. The outer sheath 40 can be made of highly resilient and skin-friendly fiber materials, making the cable softer, more flexible, and providing a better user experience. For example, the outer sheath 40 can be made of materials such as TPE or TPE composites, PVC (polyvinyl chloride) or PVC composites, or silicone.

[0042] In this embodiment, the cross-section of the magnetic transmission line 100 has a width d1 along the first direction X and a width d2 along the second direction Y. The first direction X and the second direction Y are perpendicular, and the width d1 is greater than the width d2. That is, the widths of the cross-section of the magnetic transmission line 100 along the mutually perpendicular first direction X and second direction Y are different, and the cross-section of the magnetic transmission line 100 is generally flat. The magnetic transmission line 100 is a flat wire, for example... Figure 1As shown, the cross-section of the magnetic transmission line 100 can be a rounded rectangle.

[0043] Understandably, since the width d1 is greater than the width d2, that is, the width along the first direction X is larger, the first filling portion 31, the first filling layer 20, and the second filling portion 32 can be arranged sequentially, providing ample space for the magnetic layer. For example, when the first filling layer 20 is a magnetic layer, its width can be set larger to enhance magnetic performance and thus improve the magnetic effect of the magnetic transmission line 100. When the second filling layer 30 is a magnetic layer, it can be distributed on both sides of the magnetic transmission line 100, i.e., the magnetic layer is divided into the first filling portion 31 and the second filling portion 32. By providing magnetic layers on both sides of the transmission line, the overall magnetic performance of the magnetic layer can be enhanced, thereby improving the magnetic effect of the magnetic transmission line 100. Therefore, the magnetic transmission line 100 of this embodiment can enhance the magnetic effect and make the magnetic transmission line 100 easier to store.

[0044] In some embodiments, continue to refer to Figure 1 The outer sheath 40 has a first end face 41 and a second end face 42 along the second direction Y. Both the first end face 41 and the second end face 42 are planar, and the first end face 41 is parallel to the second end face 42. Therefore, the magnetic transmission line 100 can be formed into a flat wire, facilitating user use and storage. In practical applications, one of the first end face 41 and the second end face 42 forms the S pole of the magnetic layer, and the other forms the N pole. For example, the first end face 41 can form the S pole, and the second end face 42 can form the N pole. It is understandable that since both the first end face 41 and the second end face 42 are planar, the magnetic attraction between the contacting parts of the magnetic transmission line 100 is better when stored, preventing the magnetic transmission line 100 from spreading out due to poor magnetic attraction.

[0045] The outer sheath 40 has opposing third end faces 43 and fourth end faces 44 along the first direction X. The first end face 41, third end face 43, second end face 42, and fourth end face 44 are connected sequentially. In some embodiments, such as... Figure 1 As shown, both the third end face 43 and the fourth end face 44 are planar, and the third end face 43 and the fourth end face 44 are parallel. Therefore, the magnetic transmission line 100 can be made to have a flat shape and be easy to use.

[0046] In some embodiments, reference Figure 3 The third end face 43 and the fourth end face 44 are both curved surfaces, for example, they can be semi-circular. Setting the third end face 43 and the fourth end face 44 as curved surfaces can make the surface of the magnetic transmission line 100 smooth, improve the user's tactile feel, and enhance the user experience.

[0047] In some embodiments, reference Figure 6 , Figure 6 This is a schematic diagram of the sixth cross-sectional structure of the magnetic transmission line 100 according to an embodiment of this application.

[0048] The second filling layer 30 also includes a third filling portion 33. The third filling portion 33 is connected to the first filling portion 31 and the second filling portion 32. In some embodiments, the first filling portion 31, the third filling portion 33, and the second filling portion 32 are integrally formed, for example, by one-time extrusion forming using an integral forming extrusion die. In practical applications, the shape and size of the first filling portion 31, the third filling portion 33, and the second filling portion 32 can be set according to requirements.

[0049] The first filling layer 20 is disposed around the third filling portion 33, which is disposed around at least one wire core 10, thus enabling the first filling layer 20 to be indirectly disposed around at least one wire core 10. This arrangement results in the first filling layer 20 forming two parts, located on opposite sides of the third filling portion 33. When the first filling layer 20 is a magnetic layer, the two parts located on opposite sides of the third filling portion 33 can respectively form the S pole and N pole of the magnetic layer.

[0050] In some embodiments, reference Figure 7 , Figure 7 This is a schematic diagram of the magnetic transmission line 100 in the winding state according to an embodiment of this application.

[0051] The magnetic cable 100 also includes interfaces 50 at both ends. These interfaces 50 can be various types, such as USB, USB Type-C, Lightning, HDMI, and DP, to meet the needs of different usage scenarios. The interfaces 50 at both ends of the magnetic cable 100 can be different types of interfaces or the same type of interface. The portion between the two interfaces 50 constitutes the cable portion of the magnetic cable 100, such as... Figure 7 The image shows the wire in its wound state, i.e., its stored state.
