Abstract
Description
[Technical field]
[0001] The present invention relates to the technical field of electronic devices, and in particular to a manufacturing method for a magnetic signal cable. [Background technology]
[0002] A signal cable is a charging component commonly used in electronic devices, and the signal cable is long and usually bundled or tangled when carried, so that the wires often need to be untangled when used, which is very troublesome, unsightly, and takes up space. Conventional signal cables available on the market generally have the disadvantage of being inconvenient to store, and when the signal cable is not in use, the signal cable looks messy when stored due to the flexibility characteristics of the signal cable, and especially in application scenarios where the signal cable needs to be stored in a small space such as a handbag, pocket, or backpack, the messy signal cable not only takes up a larger storage space, but also significantly affects the user's ability to pick up other items in the same space, which is inconvenient to use, very messy in appearance, and poor user experience.
[0003] To make storing signal cables easier, magnetically stored signal cables have been introduced.
[0004] For example, Patent Document 1 discloses a magnet-stored signal cable in which magnet blocks are fitted into wires, and when the signal cable is bent, the magnet blocks are magnetically attracted to each other to store the signal cable.
[0005] Furthermore, for example, Patent Document 2 discloses a magnet-stored signal cable in which one or more magnetic attraction parts are provided on a wire body, the wire body is wound so as to be stacked in a coil shape and stored together, and after winding, the magnetic attraction parts between the upper and lower layers attract each other to fix the wound wire body.
[0006] Furthermore, for example, Patent Document 3 discloses a magnetic signal cable that is convenient for storage, in which a magnetic ring is fitted into the signal cable body, and when the signal cable is to be stored, the signal cable can be neatly stored through the magnetic ring.
[0007] However, in the technical means disclosed in the above prior patent, when the signal cable is folded and stored, a magnetic attraction part (or a magnet block or a magnetic ring) is used to attract the signal cable between the upper and lower layers after winding and fix the winding. During winding, it is necessary to align and attract the magnetic attraction part (or the magnet block or the magnetic ring) between the signal cables of the upper and lower layers, which makes the operation during winding complicated and makes it difficult to control the coil diameter after winding due to the distance restriction of the magnetic attraction part (or the magnet block or the magnetic ring).

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0033] Hereinafter, the technical means in the embodiments of the present invention will be described in detail with reference to the drawings in the embodiments of the present invention, but it goes without saying that the described embodiments are only some of the embodiments of the present invention and do not include all of the embodiments. All other embodiments obtained by those skilled in the art on the basis of the embodiments of the present invention without any creative activity are all within the scope of protection of the present invention.
[0034] An "embodiment" referred to in this specification means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. Thus, phrases appearing in various places throughout this specification do not necessarily refer to the same embodiment, nor are they mutually exclusive independent or alternative embodiments with other embodiments. Those skilled in the art shall explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0035] As shown in Fig. 1, Fig. 1 is a first flow diagram of a manufacturing method for a magnetic signal cable provided in an embodiment of the present invention. The manufacturing method for a magnetic signal cable may include step 101, step 102, step 103 and step 104.
[0036] Step 101: Prepare a plurality of metal wires. The plurality of metal wires can be understood as at least two metal wires, for example, five metal wires. The material of the plurality of metal wires can be the same, for example, the plurality of metal wires are all made of metallic copper. It goes without saying that the material of the plurality of metal wires is not limited to metallic copper. For example, the plurality of metal wires can be made of an alloy material of copper and other metals. It should be understood that the plurality of metal wires defined in the embodiment of the present invention are within the scope of the embodiment of the present invention as long as they are metallic wire materials that can be used for signal transmission.
[0037] In an alternative embodiment of the present invention, the outer surface of each metal line is covered with an insulating layer to prevent the metal lines from causing signal interference with each other during operation, which also makes it easier to perform other operations on the metal lines in the next step.
[0038] Step 102: Form at least one layer of a rubber layer, which is a mixture of rubber and magnetic powder, around the plurality of metal wires.
[0039] It should be noted that in the process of molding a layer of rubber around metal wires, the metal wires must first be positioned.
[0040] For example, first, the same ends of the multiple metal wires, for example, ends A, are fixed to a first housing member, and the multiple metal wires are wound around the first housing member.
[0041] Next, the other ends of the multiple metal wires, for example, end B, are fixed to the second housing member, so that the multiple metal wires can be positioned, for example, the multiple metal wires are straightened.
[0042] A layer of rubber is then molded around the metal wires.
[0043] The step of forming a layer of rubber around the plurality of metal wires may use a tool such as a rubber coating machine, which may include a mold. The step of forming a layer of rubber around the plurality of metal wires may include the following steps:
[0044] First, a mold is defined around the plurality of metal wires. The mold is used to control the shape and size of the rubber layer, for example, the cross-sectional shape and size of the rubber layer. The cross-sectional shape and size of the rubber layer are described below with reference to the structure diagram of the magnetic signal cable.
[0045] Next, injecting a rubber liquid into the mold, and the rubber liquid is coated around the plurality of metal wires. It is noted that the rubber liquid is a mixture of at least rubber and magnetic powder, for example, the rubber liquid is a mixture of rubber and magnetic powder. Before injecting the rubber liquid into the mold or before injecting the rubber liquid into the mold, the rubber liquid needs to be heated so that the rubber liquid can flow effectively and coat evenly around the plurality of metal wires.
[0046] and removing the mold after the rubber liquid has formed a rubber layer, thereby forming a single rubber layer around a plurality of metal wires.
[0047] Finally, winding the rubber layer and the metal wires together around the second housing member, for example, by disconnecting the A-ends of the metal wires from the first housing member, connecting a motor to the second housing member, and rotating the second housing member with the motor to wind the rubber layer and the metal wires together around the second housing member.
[0048] By controlling the mold, the rubber layer has a first surface and a second surface, and the first surface and the second surface are disposed opposite each other.
[0049] Step 103: Magnetizing the rubber layer so that the rubber layer has magnetic properties.
[0050] It should be noted that in the step of magnetizing the rubber layer, the metal wires and the rubber layer also need to be positioned. The specific positioning method can be referred to the method in step 102, and the detailed description thereof will be omitted here.
[0051] After the metal wires and the rubber layer thereon are positioned, a magnetization operation can be performed with a tool such as a magnetizer, such that the first surface has a first magnetic pole and the second surface has a second magnetic pole.
[0052] The polarity of the first magnetic pole is opposite to the polarity of the second magnetic pole, for example, the polarity of the first magnetic pole is a south pole and the polarity of the second magnetic pole is a north pole, and further for example, the polarity of the first magnetic pole is a north pole and the polarity of the second magnetic pole is a south pole. The polarity of the first magnetic pole being opposite to the polarity of the second magnetic pole can also be said to be that the first magnetic pole and the second magnetic pole attract each other.
[0053] Step 104: baking the magnetic rubber layer at a preset temperature for a preset time to stabilize the magnetic pole of the rubber layer. After step 104 is completed, it can be seen that a magnetic signal cable is obtained. The magnetic signal cable is shown in Figure 2 and Figure 3, where Figure 2 is a diagram showing the appearance of a magnetic signal cable manufactured using the manufacturing method of a magnetic signal cable shown in Figure 1 of an embodiment of the present invention, and Figure 3 is a cross-sectional view of a magnetic signal cable manufactured using the manufacturing method of a magnetic signal cable shown in Figure 1 of an embodiment of the present invention.
[0054] In step 104, the metal wires and the magnetic rubber layer are put into an oven together, and the magnetic rubber layer is baked at a preset temperature for a preset time, so that the magnetic rubber layer can be shaped, so that the magnetic rubber layer becomes softer and the magnetic pole becomes more stable, which not only makes it easier to wind the magnetic signal cable, but also improves the mutual attraction and stability of the magnetic signal cable after winding, and improves the stacking stability.
[0055] The preset temperature may be in the range of 80°C to 110°C, and the preset temperature may be, for example, 85°C, 90°C, 95°C, and the like.
[0056] The preset time may be in the range of 25 minutes to 35 minutes, and the preset time may be, for example, 29 minutes, 30 minutes, 31 minutes, etc.
[0057] In the embodiment of the present invention, the rubber layer after magnetization is defined as a magnetic layer, but a rubber layer having magnetism can also be understood as a magnetic layer. The rubber layer after baking is defined as a magnetic attraction layer, and a rubber layer with a stable magnetic pole can also be understood as a magnetic attraction layer. The first surface of the rubber layer can be understood as a first surface of the magnetic layer or a first surface of the magnetic attraction layer. The second surface of the rubber layer can be understood as a second surface of the magnetic layer or a second surface of the magnetic attraction layer.
[0058] 2 and 3, since the mold limits the shape and size of the rubber layer, the width L1 of the first surface 121A is 3 mm or more, and the width L2 of the second surface 122A is 3 mm or more. For example, the width L1 of the first surface 121A is 3 mm, 3.2 mm, 3.5 mm, etc. For example, the width L2 of the second surface 122A is 3 mm, 3.2 mm, 3.5 mm, etc.
[0059] In alternative embodiments of the invention, the width L1 of the first surface 121A and the width L2 of the second surface 122A are equal, such as 3 mm, 3.2 mm, 3.5 mm, etc.
[0060] In an alternative embodiment of the invention, the first surface 121A is a planar surface and the second surface 122A is a planar surface.
[0061] In an alternative embodiment of the invention, the first surface 121A and the second surface 122A are parallel to each other.
[0062] It will be understood that an embodiment of the present invention allows the magnetic signal cable 10A to be manufactured using the magnetic signal cable manufacturing method described above, so that the magnetic signal cable 10A can include a plurality of metal wires 11A and a magnetic attraction layer 12A.
[0063] The outer surface of each metal wire 11A is covered with a single insulating layer 14A. The metal wires 11A may be spaced apart from one another. For example, the magnetic attraction layer 12A may be formed not only around the metal wires 11A, but also between the metal wires 11A.
[0064] In an alternative embodiment of the present invention, the magnetic attraction layer 12A has a first arcuate surface 123A and a second arcuate surface 124A, the first arcuate surface 123A and the second arcuate surface 124A are arranged opposite each other, the first arcuate surface 123A connects the first surface 121A and the second surface 122A, and the second arcuate surface 124A connects the first surface 121A and the second surface 122A.
[0065] It should be noted that when the magnetic signal cable 10A is wound and stacked, as shown in Figures 2 and 3, the magnetic signal cable 10A can form several turns of magnetic attraction windings, and the first and second faces of two adjacent turns of magnetic attraction windings are adjacent to each other and face each other. For example, several turns of magnetic attraction windings include a first magnetic attraction winding 15A and a second magnetic attraction winding 16A, and the first magnetic attraction winding 15A and the second magnetic attraction winding 16A are stacked and adjacent to each other, and the two adjacent faces of the first magnetic attraction winding 15A and the second magnetic attraction winding 16A, for example, the first face 121A and the second face 122A, have opposite polarities and can be attracted to each other. Since the two adjacent faces of the first magnetic attraction winding 15A and the second magnetic attraction winding 16A are shielded, the first face 121A and the second face 122A will be used as reference for the description.
[0066] It should be noted that the above manufacturing method of the magnetic signal cable may further include other steps between each step. For example, after the step of magnetizing the rubber layer and before the step of baking the magnetic rubber layer at the preset temperature within the preset time, the manufacturing method of the magnetic signal cable further includes the step of winding the magnetic rubber layer and the plurality of metal wires in a jig, forming the magnetic rubber layer into several turns of magnetic adsorption windings, and arranging the first and second surfaces of two adjacent turns of the magnetic adsorption windings adjacent to each other, and the step of baking the magnetic rubber layer at the preset temperature within the preset time includes the step of baking the magnetic rubber layer wound on the jig at the preset temperature within the preset time.
[0067] Also, for example, after the step of molding a single rubber layer around the plurality of metal wires and before the step of magnetizing the rubber layer, the manufacturing method of the magnetic signal cable further includes the step of molding a single protective layer on an outer surface of the rubber layer.
[0068] Also, for example, after the step of magnetizing the rubber layer and before the step of baking the magnetic rubber layer at the predetermined temperature for a predetermined time, the manufacturing method of the magnetic signal cable further includes a step of cutting the magnetic rubber layer and the plurality of metal wires.
[0069] Also, for example, after the step of magnetizing the rubber layer and before the step of baking the magnetic rubber layer at the predetermined temperature for a predetermined time, the manufacturing method of the magnetic signal cable includes the steps of welding a first connector to one end of the plurality of metal wires and welding a second connector to the other end of the plurality of metal wires.
[0070] An example will be given below with reference to the drawings.
[0071] In another alternative embodiment of the present invention, refer to Fig. 4, which is a second flow diagram of the manufacturing method of the magnetic signal cable provided in the embodiment of the present invention. The manufacturing method of the magnetic signal cable may include step 201, step 202, step 203, step 204, step 205, step 206, step 207, step 208 and step 209.
[0072] Step 201: Prepare a plurality of metal wires. Step 201 can refer to step 101, and detailed description thereof will be omitted here.
[0073] Step 202: A rubber layer, which is a mixture of at least one rubber and magnetic powder, is formed around the plurality of metal wires. Step 202 can be performed by referring to step 102, and a detailed description thereof will be omitted here.
[0074] Step 203: Form a protective layer on the outer surface of the rubber layer. The thickness of the protective layer is 0.6 mm or less. The protective layer can protect the rubber layer, for example, after the rubber layer is magnetized, the protective layer can reduce or eliminate the weak current in the rubber layer, thereby preventing the rubber layer from cracking and cracking. It should be noted that the thickness of the protective layer should not be too thick. Specifically, the thickness of the protective layer is 0.6 mm or less. If the thickness of the protective layer exceeds 0.6 mm, the magnetic force will be greatly weakened after the rubber layer is magnetized, which will affect the convenience of storage of the magnetic signal cable.
[0075] The step of forming a layer of protective layer on the outer surface of the rubber layer includes forming a layer of protective layer on the outer surface of the rubber layer over a layer of braided wire, it being noted that the protective layer is not limited to a braided wire, and other protective layer structures may be used.
[0076] It should be noted that in the step of forming a protective layer by covering a layer of braided wire on the outer surface of the rubber layer, the metal wires and the rubber layer also need to be positioned. The specific positioning method can be referred to the method of step 102, and the detailed description thereof will be omitted here.
[0077] Step 204: magnetizing the rubber layer so that the rubber layer has magnetic properties. Step 204 may refer to step 103, and detailed description thereof will be omitted here.
[0078] Step 205: Cutting the magnetic rubber layer and the plurality of metal wires. The magnetic rubber layer and the plurality of metal wires are cut together using a cutting machine to obtain a plurality of wires with a required length specification.
[0079] This step can be omitted because multiple metal wires can be cut beforehand and other steps can be performed. However, in the actual processing and manufacturing process, other steps are performed for each magnetic signal cable, which reduces efficiency. Therefore, the embodiment of the present invention performs the cutting step after the magnetization operation of the rubber layer is completed, thereby improving efficiency.
[0080] Step 206: Welding a first connector to one end of the plurality of metal wires, the first connector being capable of being used to plug into a mobile device, such as a mobile phone or a laptop computer.
[0081] Step 207: Welding a second connector to the other end of the plurality of metal wires, the second connector being capable of being used to plug into a power device, such as a charger.
[0082] It should be noted that the order of steps 206 and 207 may be reversed, for example, first welding the second connector to the other end of the plurality of metal wires, and then welding the first connector to one end of the plurality of metal wires.
[0083] It can be understood that before performing step 206 and step 207, it is necessary to first remove the magnetic rubber layer on both ends of the multiple metal wires. For example, remove the magnetic rubber layer part at one end of the multiple metal wires, and remove the magnetic rubber layer part at the other end of the multiple metal wires. In an actual manufacturing process, a cable stripper is used to remove the magnetic rubber layer part at one end of the multiple metal wires, and a cable stripper is used to remove the magnetic rubber layer part at the other end of the multiple metal wires.
[0084] Next, the first connector can be welded and fixed to one end of the plurality of metal wires using a wire welding machine, and the second connector can be welded and fixed to the other end of the plurality of metal wires using a wire welding machine.
[0085] In an actual manufacturing process, the first connector and one end of the plurality of metal wires can be injection molded in an injection molding machine, and the second connector and the other end of the plurality of metal wires can be injection molded in an injection molding machine.
[0086] Step 208: The magnetic rubber layer and the multiple metal wires are wound in a jig, and the magnetic rubber layer is formed into a wound layer structure of several turns, with the first and second surfaces of two adjacent wound layer structures facing each other adjacently.
[0087] Referring to Figures 5 and 6, Figure 5 is a schematic diagram of a jig provided in an embodiment of the present invention, and Figure 6 is a schematic diagram of a magnetic signal cable provided in an embodiment of the present invention wound around a jig during a manufacturing process.
[0088] The fixture 20 may have a spiral barrier structure 21 on its periphery, forming a groove structure 22 on the periphery of the fixture 20. The metal wires of the magnetic signal cable, the magnetic rubber layer, and the protective layer may be disposed in the groove structure 22. In another alternative embodiment of the present invention, the metal wires of the magnetic signal cable, the magnetic rubber layer, and the protective layer may be disposed in the groove structure 22.
[0089] In an alternative embodiment of the present invention, the outer surface of the magnetic rubber layer can conform to the groove structure 22 so that the barrier structure 21 can confine the outer surface of the rubber layer.
[0090] In another alternative embodiment of the present invention, the outer surface of the protective layer conforms to the recessed groove structure 22 so that the barrier structure 21 The outer surface of the protective layer can be limited.
[0091] Step 209: The magnetic rubber layer wound around the jig is baked at a preset temperature for a preset time. Step 209 may refer to step 104, and the detailed description thereof will be omitted here. It should be noted that if the magnetic rubber layer is wound around a jig, such as the jig 20, and then baked, the magnetic pole of the rubber layer can be further increased and made more stable. It can also be understood that the magnetic pole of the magnetic attraction layer is made more stable, and the magnetic pole of the magnetic attraction layer is prevented from being confused and causing disorderly lamination. This makes the magnetic pole of the magnetic attraction layer more stable, and the magnetic attraction winding formed after winding can be stably laminated.
[0092] Referring to Fig. 7, Fig. 7 is a diagram showing the appearance of a magnetic signal cable manufactured using the manufacturing method of a magnetic signal cable shown in Fig. 4 according to an embodiment of the present invention, and Fig. 8 is a cross-sectional view of a magnetic signal cable manufactured using the manufacturing method of a magnetic signal cable shown in Fig. 4 according to an embodiment of the present invention. The magnetic signal cable 10B can be manufactured using the manufacturing method of the magnetic signal cable described above, so that the magnetic signal cable 10B can include a plurality of metal wires 11B, a magnetic attraction layer 12B, and a protective layer 13B.
[0093] The outer surface of each metal wire 11A is covered with a single insulating layer 14A. The metal wires 11B may be spaced apart from one another. For example, the magnetic attraction layer 12B may be formed not only around the metal wires 11B but also between the metal wires 11B.
[0094] Since the mold limits the shape and size of the rubber layer, the width L3 of the first surface 121B is 3 mm or more, and the width L4 of the second surface 122B is 3 mm or more. For example, the width L3 of the first surface 121B is 3 mm, 3.2 mm, 3.5 mm, etc. For example, the width L4 of the second surface 122B is 3 mm, 3.2 mm, 3.5 mm, etc.
[0095] In alternative embodiments of the invention, the width L3 of the first surface 121B and the width L4 of the second surface 122B are equal, such as 3 mm, 3.2 mm, 3.5 mm, etc.
[0096] In an alternative embodiment of the invention, the first surface 121B is a planar surface and the second surface 122B is a planar surface.
[0097] In an alternative embodiment of the invention, the first surface 121B and the second surface 122B are parallel to each other.
[0098] In an alternative embodiment of the present invention, the magnetic attraction layer 12B has a first arcuate surface 123B and a second arcuate surface 124B, the first arcuate surface 123B and the second arcuate surface 124B are arranged opposite each other, the first arcuate surface 123B connects the first surface 121B and the second surface 122B, and the second arcuate surface 124B connects the first surface 121B and the second surface 122B.
[0099] It should be noted that when the magnetic signal cable 10B is wound and stacked, as shown in Figures 7 and 8, the magnetic signal cable 10B can form several turns of magnetic attraction winding, and the first and second faces of two adjacent turns of magnetic attraction winding are adjacent to each other and face each other. For example, several turns of magnetic attraction winding include a first magnetic attraction winding 15B and a second magnetic attraction winding 16B, and the first magnetic attraction winding 15B and the second magnetic attraction winding 16B are stacked and adjacent to each other, and the two adjacent faces of the first magnetic attraction winding 15B and the second magnetic attraction winding 16B, for example, the first face 121B and the second face 122B, have opposite polarities and can attract each other. Since the two adjacent faces of the first magnetic attraction winding 15B and the second magnetic attraction winding 16B are shielded, the first face 121B and the second face 122B will be used as reference for the description.
[0100] As shown in Figures 6 to 8, the magnetic signal cable 10B may include a first connector 17B and a second connector 18B so that the magnetic signal cable 10B can be used as a charging cable. It is understood that other connectors may be used at both ends of the magnetic signal cable 10B.
[0101] The above describes in detail the manufacturing method of the magnetic signal cable provided in the embodiment of the present invention, the magnetic signal cable manufactured by the method, and the jig used in the manufacturing process, and the present specification uses specific examples to explain the principle and implementation method of the present invention. The above description of the embodiment is only used to help understand the method and core technical idea of the present invention, and those skilled in the art will be able to change the specific implementation and application scope based on the idea of the present invention. In short, the contents of this specification should not be understood as limitations on the present invention. [Explanation of symbols]
