Description

Technical field:

[0001] The utility model relates to the technical field of wires and cables for communication transmission and power supply, in particular to a magnetically adsorbable and retractable wire and cable. Background technology:

[0002] Wires and cables are essential devices for communication, transmission and power supply. They are very long and are usually stacked and tangled together when carried. Therefore, they often need to be tied manually when used, which is very troublesome, unsightly and takes up space. Existing wires and cables on the market generally have the defect of being inconvenient to store. When the wires and cables are idle, they appear messy due to their flexible nature when stored. Especially in application scenarios where the wires and cables need to be stored in narrow spaces such as electrician tool bags and backpacks, the messy wires and cables not only occupy a larger storage space, but also seriously affect the user's access to other items in the same space.

[0003] When in use, the power cables in the cable system often need to be laid in the air. Considering that the power cables will pose a safety hazard when they are too tight, a certain length of cable is usually reserved for bundling according to the sag and pressure of the cables. Over time, various cables are mixed and entangled together, becoming very messy and difficult to manage, which brings many difficulties to the work of power workers, and is visually unsightly and has a poor user experience. Wires are also very common in life. Places such as kitchens where electrical appliances are concentrated are prone to problems such as entanglement, and in severe cases may even pose a safety hazard. Areas such as office areas where there are many wires are also prone to problems such as entanglement, which are difficult to organize and have a poor user experience.

[0004] Later, people proposed a wire with a magnetic suction function, so that the wire can be stored when in use. For example, the patent announcement number CN213717212U discloses a magnetic suction data cable that is easy to store, which includes: a data cable body and a first data cable connector and a second data cable connector distributed at both ends of the data cable body. The data cable body is sleeved with multiple sections of data cable sleeves. A magnetic suction ring is sleeved on the data cable body between the first section of the data cable sleeve and the first data cable connector, between the last section of the data cable sleeve and the second data cable connector, and between two adjacent sections of the data cable sleeves. The data cable sleeve is a silicone hose. This magnetic suction data cable that is easy to store has the advantages that existing products do not have, such as convenient storage, neat and beautiful appearance, small space occupation, and novel appearance.

[0005] However, this existing magnetic wire has the following shortcomings due to its structural design characteristics:

[0006] 1. It realizes magnetic absorption by setting multiple magnetic rings with magnetic force around the wire. There is a problem that, on longer wires, except for the positions where the magnetic rings are set, most of the segments do not have magnetic absorption ability, so that when magnetic absorption is performed, the magnetic absorption can only be performed by aligning the magnetic rings. The adsorption method is limited, and automatic adsorption and multi-line parallel adsorption cannot be achieved. When this solution needs to be applied to wires and cables, there will still be problems that also exist in conventional wires, such as manual wiring and length adjustment for storage, which is not convenient to use.

[0007] 2. The magnetic ring is formed by two magnetic half rings that are plugged in and spliced ​​together, and then a transparent fluorescent ring is wrapped around the magnetic ring for reinforcement. This also brings problems, that is, the structure is not simplified enough, which affects the production speed, and the production cost is relatively higher, which is not convenient for production management. In addition, the wires are often tangled together during use. For such a plug-in splicing structure, once the transparent fluorescent ring is worn, the two magnetic half rings will also fall off. The service life needs to be strengthened, and its durability in various different scenarios also needs to be verified.

[0008] In view of this, the inventor proposes the following technical solution. Utility model content:

[0009] The utility model aims to overcome the deficiencies of the prior art and to provide a wire and cable which is magnetic, absorbable and retractable, has a relatively low production cost, and is fireproof and durable.

[0010] In order to solve the above technical problems, the utility model adopts the following technical solution: a magnetically adsorbable and retractable wire and cable, comprising a wire body, characterized in that:

[0011] The wire body includes a wire core, a protective layer wrapped around the outer periphery of the wire core, a first soft magnet fixed on one side of the protective layer and having magnetic force to achieve magnetic absorption, and a second soft magnet fixed on the other side of the protective layer and having magnetic force to achieve magnetic absorption.

[0012] Furthermore, in the above technical solution, the protective layer is integrally formed and wrapped around the wire core, and a first avoidance surface and a second avoidance surface are respectively formed on both sides of the protective layer.

[0013] Furthermore, in the above technical solution, the first soft magnetic body is correspondingly pasted on the first avoidance surface; the second soft magnetic body is correspondingly pasted on the second avoidance surface.

[0014] Furthermore, in the above technical solution, the first soft magnetic body and the second soft magnetic body are integrally extruded with the protective layer.

[0015] Furthermore, in the above technical solution, the wire core includes a metal conductor and an insulating layer integrally formed and wrapped around the outside of the metal conductor, and the protective layer is integrally formed and wrapped and wound around the insulating layer.

[0016] Furthermore, in the above technical solution, the ratio of the longitudinal cross-sectional area of ​​the protective layer to the first soft magnetic body and the second soft magnetic body is at least 6:1.

[0017] Furthermore, in the above technical solution, a third soft magnet and a fourth soft magnet each having magnetic force to achieve magnetic absorption are respectively arranged on the outside of the protective layer, and the third soft magnet is respectively connected to the first soft magnet and the second soft magnet, and the fourth soft magnet is respectively connected to the first soft magnet and the second soft magnet.

[0018] Furthermore, in the above technical solution, the molding on the first soft magnetic body helps the wire body to be adsorbed stably on the first adsorption surface, and the molding on the second soft magnetic body helps the wire body to be adsorbed stably on the second adsorption surface.

[0019] Furthermore, in the above technical solution, a connector is provided at one end of the wire body, and the connector is at least one of an electric plug and a data connector.

[0020] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: in the utility model, by respectively arranging the first soft magnet and the second soft magnet on both sides of the protective layer, the first soft magnet and the second soft magnet are extruded and shaped together with the protective layer at one time, or the first soft magnet and the second soft magnet are extruded and formed separately from the protective layer, wherein, when the protective layer is extruded and formed, the positions of the first soft magnet and the second soft magnet are reserved in advance, and the first soft magnet and the second soft magnet are combined through secondary pasting and introduction processes, and further, the combined wire body is wound according to a predetermined pattern, and after the wire is wound, it is baked and shaped, and further, the shaped wire body is placed in a magnetizing device for magnetization, and after the magnetization is completed, a finished wire body that can be automatically adsorbed, automatically stored, and automatically magnetically wound back to a predetermined pattern is obtained; this scheme eliminates the need for a magnetic attraction ring, and magnetic absorption is achieved through the first soft magnet and the second soft magnet, and any segment of the wire body has magnetic force, can be adsorbed and stored, and can automatically be magnetically attracted and automatically wound. Returning to the established style, it can also achieve multi-line parallel adsorption, and this solution is suitable for application to wires and cables. The utility model can effectively solve and improve the problems of traditional wires that are easy to knot and entangle, difficult to organize and not portable. Through magnetic force, it can be quickly organized, automatically adsorbed, and can be long or short. The multi-line integration, detachable and combinable mode can adapt to various work scenes, without manual wire tying and length adjustment for storage, which can bring great convenience to people's lives and greatly reduce the work pressure of power workers; in addition, after eliminating the magnetic suction ring, it can avoid the assembly method of plugging and splicing two magnetic suction half rings, and adopt extrusion molding, so that the structure is simple and durable, without small parts, easy to produce and manage, and reasonable production cost, and once magnetized, the magnetism will not be reduced after long-term use, and the integral extrusion or bonding molding method enables the first soft magnet and the second soft magnet to be firmly set on the protective layer without falling off. Even if it is subject to certain wear, it will not lose the magnetic suction function. It is suitable for a variety of different work scenes and can solve the user's pain points.

[0028] The utility model is further described below in conjunction with specific embodiments and drawings.

[0029] See Figures 1 to 6 As shown, a magnetically absorbable and retractable wire and cable includes a wire body 10, characterized in that:

[0030] The wire body 10 includes a wire core 110, a protective layer 120 wrapped around the outer periphery of the wire core 110, a first soft magnetic body 310 fixed to one side of the protective layer 120 and having magnetic force to achieve magnetic absorption, and a second soft magnetic body 320 fixed to the other side of the protective layer 120 and having magnetic force to achieve magnetic absorption. The wire core 110 has two or more cores.

[0031] In terms of structural implementation, the utility model realizes the magnetic absorption function of the wire body 10 by respectively arranging the first soft magnetic body 310 and the second soft magnetic body 320 on both sides of the protective layer 120, and the first soft magnetic body 310 and the second soft magnetic body 320 are extruded and shaped together with the protective layer 120 at one time; or, the first soft magnetic body 310 and the second soft magnetic body 320 are extruded and formed separately from the protective layer 120, wherein the protective layer 120 is extruded and formed, and the first soft magnetic body 310 and the second soft magnetic body 320 are extruded and formed separately from the protective layer 120. 0 is reserved first, the first soft magnetic body 310 and the second soft magnetic body 320 are combined through secondary pasting and introduction process, further, the combined wire body 10 is overlapped and wound according to the established style (such as: the wire body 10 in the middle part is folded into a spiral shape), and after winding, it is baked and shaped, and further, the shaped wire body 10 is placed in a magnetizing device for magnetization. After the magnetization is completed, the finished wire body 10 that can be automatically adsorbed, automatically stored, and automatically magnetically reeled back into the established style is obtained;

[0032] This solution eliminates the need for a magnetic ring, and achieves magnetic absorption through the first soft magnet 310 and the second soft magnet 320. Any segment of the wire body 10 has magnetic force, and any segment can be freely absorbed and stored, and can automatically be magnetically absorbed and automatically rolled back into a predetermined style, and can also achieve parallel absorption of multiple wires. Applying this solution to wires and cables can effectively solve and improve the problems of traditional wires being easy to knot, entangled, difficult to organize and not portable. Through magnetic force, they can be quickly organized, automatically absorbed, and can be long or short. The multi-wire integration, detachable and combinable method can adapt to various work scenarios, and there is no need to manually tie the wires and adjust the length for storage, which can bring great convenience to life. It is not only beneficial, but also can greatly reduce the work pressure of power workers. In addition, after eliminating the magnetic ring, the assembly method of two magnetic half rings plugged together can be avoided, and extrusion molding is adopted, so that the structure is simple and durable, without small parts, easy to produce and manage, and reasonable production cost. Moreover, once magnetized, the magnetism will not be reduced after long-term use. The integral extrusion or bonding molding method allows the first soft magnet 310 and the second soft magnet 320 to be firmly set on the protective layer 120 without falling off. Even if part of it is worn to a certain extent, it will not lose the magnetic attraction function. It is suitable for a variety of different working scenarios and can solve the user's pain points.

[0033] In the first embodiment of the present invention, see Figures 1 to 5 As shown, the protective layer 120 is integrally formed and wrapped around the core 110, and the first avoidance surface 121 and the second avoidance surface 122 are formed on both sides of the protective layer 120. The first soft magnetic body 310 is correspondingly attached to the first avoidance surface 121; the second soft magnetic body 320 is correspondingly attached to the second avoidance surface 122.

[0034] The wire core 110 includes a metal conductor 41 and an insulating layer 40 integrally formed and wrapped around the metal conductor 41 . The protective layer 120 is integrally formed and wrapped around the insulating layer 40 .

[0035] The ratio of the longitudinal cross-sectional area of ​​the protective layer 120 to the first soft magnetic body 310 and the second soft magnetic body 320 is at least 6:1. The longitudinal cross-sectional area is the cross-sectional area obtained by radially cutting the wire body 10.

[0036] The first soft magnetic body 310 is formed with a first adsorption surface 311 that helps the wire body 10 to be adsorbed stably, and the second soft magnetic body 320 is formed with a second adsorption surface 321 that helps the wire body 10 to be adsorbed stably. The first adsorption surface 311 and the second adsorption surface 321 can help the wire body 10 to be stable when adsorbed, rolled back and overlapped. According to tests, the arc surface is prone to shaking due to uneven force when automatically adsorbed, rolled back and overlapped. After adding the first adsorption surface 311 and the second adsorption surface 321, the wire body 10 is more stable and more beautiful in appearance when automatically adsorbed, rolled back and overlapped.

[0037] A connector 20 is disposed at one end of the wire body 10 , and the connector 20 is at least one of an electrical plug and a data connector.

[0038] In the second embodiment of the present utility model, see Figures 2 to 5 As shown, compared with the first embodiment, the only difference is the molding method. The first soft magnet 310 and the second soft magnet 320 are integrally extruded with the protective layer 120. The rest of the structure is consistent with the first embodiment, and the assembly process is consistent with the first embodiment, which will not be repeated.

[0039] In the third embodiment of the present invention, see Figure 6 As shown, the wire core 110 includes a metal conductor 41 and an insulating layer 40 integrally formed and wrapped around the outside of the metal conductor 41, the protective layer 120 is integrally formed and wrapped around the insulating layer 40; the protective layer 120 is wrapped around the outside of the insulating layer 40; the outside of the protective layer 120 is also provided with a third soft magnetic body 330 and a fourth soft magnetic body 340 respectively having magnetic force to achieve magnetic absorption, and the third soft magnetic body 330 is respectively connected to the first soft magnetic body 310 and the second soft magnetic body 320, and the fourth soft magnetic body 340 is respectively connected to the first soft magnetic body 310 and the second soft magnetic body 320. In this embodiment, in terms of structure, only the soft magnetic layer 50 is completely wrapped around the protective layer 120. This solution is suitable for scenarios with high magnetic force requirements for the wire body 10, such as data cables for mobile devices.

[0040] In the fourth embodiment of the present utility model, see Figure 7 As shown, compared with implementation one, a layer of fiber braid 200 is added on top of the structural shape of implementation one. The fiber braid 200 can well protect the protective layer 120, the first soft magnet 310 and the second soft magnet 320 from being damaged, can effectively enhance the strength of the cable, improve durability, and can also enrich the color appearance, making the product more popular with users.

[0041] In summary, in terms of structural implementation, the utility model realizes the magnetic absorption function of the wire body 10 by respectively arranging the first soft magnetic body 310 and the second soft magnetic body 320 on both sides of the protective layer 120, and the first soft magnetic body 310 and the second soft magnetic body 320 are extruded and shaped together with the protective layer 120 at one time, or the first soft magnetic body 310 and the second soft magnetic body 320 are extruded and formed separately from the protective layer 120, wherein when the protective layer 120 is extruded and formed, the positions of the first soft magnetic body 310 and the second soft magnetic body 320 are reserved in advance, and the first soft magnetic body 310 and the second soft magnetic body 320 are respectively extruded and formed. The first soft magnetic body 310 and the second soft magnetic body 320 are combined through secondary pasting and introduction process. Further, the combined wire body 10 is wound according to the predetermined pattern. After the winding is completed, it is baked and shaped. Further, the shaped wire body 10 is placed in a magnetizing device for magnetization. After the magnetization is completed, a finished wire body 10 that can be automatically adsorbed, automatically stored, and automatically magnetically wound back into a predetermined pattern is obtained. This solution eliminates the magnetic attraction ring, and magnetic absorption is achieved by the first soft magnetic body 310 and the second soft magnetic body 320. Any segment of the wire body 10 has magnetic force. The utility model can effectively solve and improve the problems of traditional electric wires being easy to get tangled and entangled, being difficult to organize and not portable. It can quickly organize and automatically absorb through magnetic force. It can be long or short. The multi-wire integration, detachable and combinable mode can adapt to various work scenes. There is no need to manually tie the wires and adjust the length for storage. It can bring great convenience to people's lives and greatly reduce the work pressure of power workers. In addition, in the free After removing the magnetic ring, the assembly method of two magnetic half rings plugged together can be avoided, and extrusion molding is adopted, so that the structure is simple and durable, without small parts, easy to manage and have reasonable production costs. Moreover, once magnetized, the magnetism will not diminish after long-term use. The one-piece extrusion or bonding molding method allows the first soft magnet 310 and the second soft magnet 320 to be firmly set on the protective layer 120 without falling off.
