Please refer to Figures 1 and 2, which are schematic diagrams of the first embodiment of the portable transmission cable 1 of the present invention. As shown in the figure, the portable transmission cable 1 of the present invention includes a transmission cable 100, at least one magnetic member 70, a first connection port 101 and a second connection port 102. The first connection port 101 is disposed at one end of the transmission cable 100 and electrically connected to the transmission cable 100. The second connection port 102 is disposed at the other end of the transmission cable 100 and electrically connected to the transmission cable 100. By the way, the first connection port 101 may be the same as or different from the second connection port 102, and the first connection port 101 and the second connection port 102 may be interfaces that comply with standard specifications, such as Mini USB, Micro USB, USB Type-C, Lightning, Thunderbolt, etc.

The transmission line 100 includes a core 10, a shielding member 30 and a protective member 11. The shielding member 30 covers the core 10, and the protective member 11 covers the shielding member 30. At least one magnetic member 70 is disposed outside the core 10 or the shielding member 30.

Specifically, the shielding member 30 may be a hollow column. The magnetic member 70 is disposed on at least one of the inner and outer sides of the shielding member 30, and the magnetic member 70 extends relative to the length direction of the shielding member 30. When the transmission line 100 is wound and stored, the transmission line 100 is wound and stacked, and the magnetic member 70 forms an overlapping magnetic field in the stacking area of the transmission line 100. The transmission line 100 is wound and stacked by magnetic force so as to facilitate storage without being messy.

In other words, the transmission line 100 has a shielding member 30 and a magnetic member 70. The shielding member 30 may be made of aluminum foil, which may form a columnar thin layer extending along the length direction of the transmission line 100. The shielding member 30 may shield the internal signal from radiating to the outside. The magnetic member 70 may be arranged on at least one side of the inner side and the outer side of the shielding member 30, and the magnetic member 70 may extend relative to the length direction of the shielding member 30. When the transmission line 100 is wound and stored, the transmission line 100 is wound in layers, and the magnetic field generated around the transmission line 100 will have an overlapping area (as shown in the dotted area A in Figure 2). The overlapping magnetic fields can attract each other, so that the upper and lower wires (transmission line 100) are tightly stacked together. Among them, the attractive force can be adjusted accordingly according to the addition ratio of electromagnetic powder and the magnetization power. The distribution of the electromagnetic field after the transmission line 100 is stored and rolled is shown in Figure 6. The entire winding area is full of electromagnetic fields, and the wires are naturally stacked together without spreading out, achieving a convenient storage effect.

Thus, the transmission line 100 is provided with a magnetic part 70 on at least one side of the inner side and the outer side of the shielding part 30, wherein the magnetic part 70 can generate an electromagnetic field using magnetic powder. During the winding and storage process of the transmission line 100, the curled data line 100 is stacked up and down, and the magnetic part 70 can form an overlapping magnetic field in the stacking area of the transmission line 100. Under the action of the magnetic field, the stacking area of the transmission line 100 is adsorbed together, which is convenient for storage. At the same time, it can meet the curling of any size of the transmission line 100, making storage easier.

By the way, the protective member 11 is arranged on the outer surface of the transmission line 100, which can protect the inner core wire and the middle quilt of the transmission line 100. The protective member 11 mainly protects the middle quilt and the shielding member 30 and other structures inside it, and reduces the impact of the environment on the magnetic member 70. The protective member 11 can adjust the appearance of the transmission line 100 and the resistance of the transmission line 100 to harsh environments. The resistance to harsh environments includes fire resistance, UV resistance, aging resistance, high and low temperature resistance, etc.

In this embodiment, the magnetic member 70 is set on the wire core 10 as a demonstration. The magnetic member 70 can be laid on the inner side of the shielding member 30, or filled between different wires inside the shielding member 30, to ensure that the entire winding area of the transmission line 100 is full of electromagnetic fields, and the wires are naturally stacked together without being scattered, achieving a convenient storage effect.

Specifically, the wire core 10 includes a ground wire 20, two signal wires and a power wire 60; wherein the two signal wires may be a first signal wire 40 and a second signal wire 50. The number of the magnetic component 70 is one, which is disposed on the ground wire 20. The ground wire 20 includes a ground wire conductor 21 and a ground wire insulator 22. The magnetic component 70 is coated on the outer periphery of the ground wire conductor 21, and the ground wire insulator 22 is coated on the outer periphery of the magnetic component 70.

In the embodiment, the magnetic member 70 can be formed of electromagnetic powder. While the transmission line 100 is designed to be convenient for storage, a conductive material is added to the ground wire insulator 22 to form a conductive layer, so that the insulating rubber material of the ground wire insulator 22 changes from non-conductive to conductive, and the aluminum foil and the ground wire 20 can be connected. By adding conductive material to the ground wire 20, the conduction between the aluminum foil and the ground wire 20 is guaranteed, and the subsequent processing is convenient, ensuring that the ground wire 20 does not need to be twisted and soldered when it is connected to the connector in the future.

By the way, electromagnetic powder and conductive material can be mixed into the rubber of the ground wire insulator 22 to form a composite layer of the magnetic component 70 and the conductive layer. After the ground wire conductor 21 is twisted, another layer of rubber mixed with electromagnetic powder and conductive material is pressed on the outside of the ground wire conductor 21 to make the ground wire insulator 22 a conductor, so that the ground wire 20 can be connected to the aluminum foil (shielding component 30). At the same time, the ground wire insulator 22 doped with electromagnetic powder will generate an electromagnetic field after magnetization. As shown in FIG2 , the magnetic field can pass through the aluminum foil and the outer wall of the transmission line 100, and form a magnetic field around the outside of the transmission line 100. When the wire is stored and bent, the protective member 11 of the transmission line 100 will be stacked up and down, and the magnetic field generated around the wire will appear an overlapping area (as shown in area A in FIG2 ). The overlapping magnetic fields can generate attraction to each other, so that the upper and lower wires are tightly stacked together. Among them, the attraction force can be adjusted accordingly according to the addition ratio of electromagnetic powder to the glue material in the ground wire insulator 22 and the magnetizing power. The electromagnetic field distribution after the wire is stored and curled is shown in Figure 6. The entire winding area is full of electromagnetic fields, and the wires are naturally stacked together without spreading, achieving a convenient storage effect.

Please refer to Figure 3, which is a structural schematic diagram of the second embodiment of the present invention. In this embodiment, the configuration and operation of the components with the same component symbols are the same or similar to those of the aforementioned embodiments, and the same or similar parts will not be repeated here. In this embodiment, the number of magnetic components 70 is plural, for example, four, which can be changed according to actual application. Among them, the magnetic component 70 is a magnetic wire configured along the length direction of the transmission line 100, and the magnetic wire can be formed by electromagnetic powder, for example.

In this embodiment, each magnetic member 70 is disposed between the shielding member 30 and two of the grounding wire 20, at least two signal wires, and the power wire 60. That is, the magnetic member 70 is located between the grounding wire 20, the first signal wire 40, and the shielding member 30; the magnetic member 70 is located between the first signal wire 40, the power wire 60, and the shielding member 30; the magnetic member 70 is located between the power wire 60, the second signal wire 50, and the shielding member 30; the magnetic member 70 is located between the second signal wire 50, the grounding wire 20, and the shielding member 30.

Please refer to FIG. 4, which is a schematic diagram of the structure of the third embodiment of the present invention. In this embodiment, the configuration and operation of the components with the same component symbols are the same or similar to those of the aforementioned embodiments, and the same or similar parts will not be repeated here. In this embodiment, the number of magnetic components 70 is plural, for example, three, which can be changed according to actual application. The magnetic component 70 is a magnetic wire arranged along the length direction of the transmission line 100, and the magnetic wire can be formed by electromagnetic powder, for example. In this embodiment, the ground line 20, the first signal line 40, the second signal line 50 and the power line 60 are arranged in a ring shape along the inner side of the shielding member 30, so that the ground line 20, the first signal line 40, the second signal line 50 and the power line 60 surround an area, and the magnetic member 70 is disposed in the area.

By the way, the first signal line 40 includes a first signal line conductor 41 and a first signal line insulator 42 wound around the first signal line conductor 41. The second signal line 50 includes a second signal line conductor 51 and a second signal line insulator 52 wound around the second signal line conductor 51. The power line 60 includes a power line conductor 61 and a power line insulator 62 wound around the outer periphery of the power line 60. The power line conductor 61 is mainly used for power supply. In addition, the specific number and arrangement of the ground line 20, the first signal line 40, the second signal line 50 and the power line 60 are not limited.

The following will explain the relevant implementation when the magnetic member 70 is disposed outside the shielding member 30.

Please refer to Figure 5, which is a schematic diagram of the fourth embodiment of the portable transmission line of the present invention. In this embodiment, the configuration and operation of the components with the same component symbols are the same or similar to those of the aforementioned embodiments, and the same or similar parts will not be repeated here. As shown in the figure, in this embodiment, the magnetic component 70 is arranged between the shielding component 30 and the protective component 11.

That is to say, the magnetic member 70 can be arranged on the outer side of the shielding member 30, and the magnetic member 70 can extend along the length direction and circumferential direction of the outer surface of the shielding member 30, ensuring that the entire winding area of the transmission line 100 is full of electromagnetic field, and the wires are naturally stacked together without being scattered, achieving a convenient storage effect.

When the middle or ground wire insulator 22 of the transmission line 100 is magnetized by the magnetic member 70, an electromagnetic field force is generated, and the magnetic field force passes through the protective member 11 to form a magnetic field around the outside of the wire. When the transmission line 100 is stored and curled, different sections of the transmission line 100 are stacked up and down. The magnetic field generated around the transmission line 100 will form an overlapping area. The overlapping magnetic fields can attract each other, allowing the adjacent sections of the transmission line 100 to be tightly stacked together, realizing simple and quick storage of the transmission line 100, preventing the transmission line 100 from being easily crushed or damaged due to being placed on the ground in a mess, thereby causing a short circuit in the wire, shortening the service life of the wire, and avoiding the risk of causing a fire.

Please refer to Figure 7, which is a schematic diagram of the structure of the fifth embodiment of this invention. In this embodiment, the configuration and operation of the components with the same component symbols are the same or similar to those of the aforementioned embodiments, and the same or similar parts will not be repeated here.

As shown in the figure, in this embodiment, there are multiple magnetic members 70, preferably, the magnetic members 70 are magnetic lines or columns along the length direction of the transmission line 100. Among them, multiple magnetic members 70 are arranged between the shielding member 30 and the protective member 11. In other words, the magnetic member 70 can be arranged as multiple columns surrounding the shielding member 30 and the protective member 11, and the multiple magnetic members 70 can be arranged in a row in the length direction of the shielding member 30. Thus, when the transmission line 100 is stored and rolled up, different sections of the transmission line 100 will be stacked up and down, and the magnetic field generated around the transmission line 100 will have an overlapping area (the magnetic field is similar to the dotted area A in Figure 2). The overlapping magnetic fields can attract each other, so that different sections of the transmission line 100 are tightly stacked up and down, realizing simple and fast storage of the transmission line 100, preventing the transmission line 100 from being easily crushed or damaged due to being placed on the ground in a mess, thereby causing a short circuit of the wire, shortening the service life of the wire, and avoiding the risk of causing a fire.

Please refer to Figure 8, which is a schematic diagram of the structure of the sixth embodiment of this invention. In this embodiment, the configuration and operation of the components with the same component symbols are the same or similar to those of the aforementioned embodiments, and the same or similar parts will not be repeated here.

As shown in the figure, in this embodiment, when the at least one magnetic member 70 is disposed outside the shielding member 30, the at least one magnetic member 70 covers the shielding member 30, and a waterproof coating 80 is further disposed on the outer side of the at least one magnetic member 70. In other words, the waterproof coating 80 is paved on the outer wall surface of the magnetic member 70. In this way, the magnetic member 70 can be formed as the protective member 11 of the transmission line 100 as in the aforementioned embodiment.

Alternatively, the protective member 11 of the transmission line 100 can be integrated into one component by pressing a layer of electromagnetic powder, thereby ensuring that the overall structure and process are simpler. By providing a waterproof coating 80 on the outermost layer of the transmission line 100, the waterproof performance of the transmission line 100 is further improved, and the service life of the transmission line 100 is extended.

Please refer to Figure 9, which is a schematic diagram of the structure of the seventh embodiment of this invention. In this embodiment, the configuration and operation of the components with the same component symbols are the same or similar to those of the aforementioned embodiments, and the same or similar parts will not be repeated here.

As shown in the figure, in this embodiment, the at least one magnetic member 70 is wrapped around the outer periphery of the protective member 11, and a waterproof coating 80 is further provided on the outer side of the at least one magnetic member 70. There are multiple magnetic members 70, preferably, the magnetic member 70 is a magnetic wire or column along the length direction of the transmission line 100. There are multiple magnetic members 70 surrounding the protective member 11.

In summary, the portable transmission cable of this invention can be extruded and formed at one time during the wire drawing stage, and does not require subsequent assembly, saving costs. When the transmission cable is stored, no matter what size the wire is wound, the electromagnetic field is distributed throughout the winding area, which can generate attraction between the wires, allowing the wires to automatically adsorb together and not spread out, thereby achieving the storage effect. At the same time, electromagnetic powder and conductive materials are added inside the wire, and the appearance of the wire is the same as other wires, which does not affect the appearance, and the wire diameter can be made smaller. In short, under the action of the magnetic field, the overlapping parts of the transmission line are adsorbed together, which is convenient for storage, and can also meet the curling of any size of the transmission line, making storage easier.

The above is for illustrative purposes only and is not intended to be limiting. Any equivalent modification or change made to the invention without departing from the spirit and scope of the invention shall be included in the scope of the patent application attached hereto.
