Description

Technical field:

[0001] The utility model relates to the technical field of wire materials for communication transmission and power supply, in particular to a wire material with magnetic force that can be automatically curled. Background technology:

[0002] Wire is a metal product. It can be a small diameter wire or other shaped material. It is usually continuous and very long. Wire can be supplied in coils, so it is also called coil or round. Wire is widely used, including but not limited to electrical, electronic, construction, transportation, machinery and other fields, used as connectors, supports or as raw materials. Wires and cables are common wires in life. They are necessary devices for communication, transmission and power supply. Because wires and cables are very long, they are generally stacked and entangled when carried. Therefore, they often need to be manually tied when used, which is very troublesome, unsightly and space-consuming. Traditional wires and cables are easy to knot and entangle, and not easy to store. When using, the cables need to be manually tied and the length adjusted according to the scene for use or storage management. When a single line or multiple lines are needed, it is necessary to use cable ties to tie the lines, which makes the work scene more and more messy. The messy wires and cables not only occupy a larger storage space, but also cause safety problems in serious cases.

[0003] When in use, manual wire winding and storage is not only slow, but also often uneven winding occurs during the storage process, resulting in uneven center distribution, which increases the cost of wire storage and the difficulty of transportation; in addition, if the wire is not fully stretched before winding, the stress remaining on the surface and inside of the wire will cause the wire wound onto the reel to curl and deform, and it cannot be tightly combined with the reel, which will also affect the quality and efficiency of wire winding.

[0004] For such problems, some people have proposed technical solutions, such as the Chinese utility model patent with patent announcement number CN209844470U, which discloses an FFC flat cable that is easy to store, including a cable and a cover plate. A fixed seat is provided at the rear end of the cable, and the left end of the fixed seat is connected to the movable rod through a lifting groove, and the left end of the movable rod is connected to the connecting plate through a card slot and a card block, and a handle is fixed to the left end of the connecting plate. At the same time, sliders are fixed to the upper and lower ends of the connecting plate, and the sliders are connected to the fixed seat through a movable groove. The right end of the lower surface of the cover plate is connected to the movable rod through a fixed column and a fixed groove. This existing cable is easy to install and fix, and the length of the cable can be retracted by setting a movable rod.

[0005] However, this existing flat cable has the following shortcomings due to its own structural design characteristics:

[0006] 1. This technical solution is only applicable to flat cables and is not applicable to other types of wires and cables.

[0007] 2. In this technical solution, the connecting plate is pushed to the right through the structure of the slider and the connecting rod, which makes it easier to store the cables. Such a structure is limited to storing the wires into coils, but cannot achieve automatic adsorption and multi-wire parallel adsorption. When this solution needs to be applied to wires and cables, there will still be problems that also exist in conventional wires, such as the need for manual wiring and length adjustment for storage. The problem of needing to use cable ties to organize the cables needs to be strengthened, and the functionality needs to be strengthened.

[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 provide a wire material with magnetic force that can automatically curl.

[0010] In order to solve the above technical problems, the utility model adopts the following technical solution: a wire material with magnetic force that can be automatically curled, including a wire material body, characterized in that:

[0011] The wire body includes a wire core, a protective layer wrapped around the outer periphery of the wire core, and a soft magnetic strip passing through the protective layer and having magnetic force to achieve magnetic absorption. The protective layer is formed with a plurality of through holes for the soft magnetic strip to pass through.

[0012] Furthermore, in the above technical solution, the plurality of through holes are respectively distributed around the wire core, and a soft magnetic strip is correspondingly inserted into each through hole.

[0013] Furthermore, in the above technical solution, the molding of one side of the protective layer helps the wire body to be adsorbed stably on the first adsorption surface, and the molding of the other side of the protective layer helps the wire body to be adsorbed stably on the second adsorption surface.

[0014] Furthermore, in the above technical solution, the soft magnetic strip is extruded as one piece; the protective layer is also extruded as one piece.

[0015] Furthermore, in the above technical solution, the cross-sectional shape of the protective layer is a lotus root core shape, and correspondingly, the cross-sectional shape of the soft magnetic strip is one of an ellipse and a polygon.

[0016] Furthermore, in the above technical solution, the ratio of the longitudinal cross-sectional area of ​​the protective layer to that of the soft magnetic strip is 6:1.

[0017] 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.

[0018] Furthermore, in the above technical solution, a connector is provided at one end of the wire body, and the connector is an electrical plug.

[0019] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: in the utility model, the scheme of achieving the magnetic absorption effect by pulling and inserting the soft magnetic strip is highly feasible, has a simple and practical structure, is easy to manufacture, and can be applied to most types of wires and cables, especially small-sized wires with relatively lower magnetic requirements, such as data cables, etc. Such small-sized wires have relatively lower magnetic requirements when stored due to their own small mass, and since the cost of the soft magnetic strip is higher than that of the protective layer, in order to optimize the production cost, the protective layer is made into a lotus core shape, and then the soft magnetic strip is pulled and inserted, which can not only achieve the magnetic absorption effect, but also reduce the material used for the soft magnetic strip and reduce the cost; at the same time, in this scheme, any segment of the wire body has magnetic force and can absorb It has storage, automatic magnetic attraction, automatic rewinding into a set style, and can also achieve parallel attraction of multiple lines. This solution is suitable for application to wires and cables and other wires, which can effectively solve and improve the problems of traditional wires being easily knotted and entangled. It can be quickly sorted and automatically adsorbed through magnetic force, and can be long or short. There is no need to manually tie the wires and adjust the length for storage, which can bring great convenience to people's lives and greatly reduce the work pressure of power workers. In addition, once the wire body is magnetized, the magnetism will not diminish after long-term use. The combination of the protective layer and the soft magnetic strip is extruded into one piece and then inserted for the second time, so that the protective layer can well protect the soft magnetic strip, and the soft magnetic strip will not wear out and lose magnetism, and will not lose the magnetic attraction function after long-term use. It is suitable for a variety of different work scenarios, easy to manage in production, and has a reasonable production cost. Description of the drawings:

[0025] The utility model is further described below in conjunction with specific embodiments and drawings.

[0026] See Figures 1 to 5 As shown, a wire material having magnetic force and capable of automatically curling includes a wire material body 100, characterized in that:

[0027] The wire body 100 includes a wire core 20, a protective layer 30 wrapped around the outer periphery of the wire core 20, and a soft magnetic strip 40 passing through the protective layer 30 and having magnetic force to achieve magnetic absorption. The protective layer 30 is formed with a plurality of through holes 50 for the soft magnetic strip 40 to pass through.

[0028] In terms of structural implementation, the utility model reserves a plurality of through holes 50 in the protective layer 30, makes the protective layer 30 into a lotus core shape, and then inserts the soft magnetic strips 40 into the through holes 50 in a pulling manner, and one soft magnetic strip 40 is correspondingly inserted into each through hole 50, wherein the soft magnetic strips 40 and the protective layer 30 are extruded and formed as one piece respectively, and then combined into one piece by pulling and inserting; further, the assembled wire body 100 is wound according to a predetermined pattern (such as: the middle part of the wire body 100 is overlapped in a spiral shape), and after the wire is wound, it is baked and shaped, and finally, the shaped wire body 10 is placed in a magnetizing device for magnetization, and after the magnetization is completed, a finished wire body 100 that can automatically adsorb, automatically store, and automatically magnetically reel back into a predetermined pattern is obtained.

[0029] The above-mentioned scheme of achieving the magnetic absorption effect by pulling and inserting the soft magnetic strip 40 is highly feasible, has a simple and practical structure, is easy to manufacture, and can be applied to most types of wires and cables, especially small-sized wires with relatively lower magnetic requirements, such as data cables, etc. This type of small-sized wire has a relatively low mass, so that when it is stored, the requirement for magnetic force is relatively low. Moreover, since the cost of the soft magnetic strip 40 is higher than that of the protective layer 30, in order to optimize the production cost, the protective layer 30 is made into a lotus core shape, and then pulled and inserted into the soft magnetic strip 40, which can not only achieve the magnetic absorption effect, but also reduce the material used for the soft magnetic strip 40 and reduce the cost. At the same time, in this scheme, any segment of the wire body 100 has magnetic force, can be adsorbed and stored, and can automatically be magnetically absorbed and automatically rolled back into a predetermined style. , and can also realize the adsorption of multiple lines in parallel. This solution is suitable for application to wires such as wires and cables, which can effectively solve and improve the problems of traditional wires being easy to get tangled and entangled, difficult to organize and not portable. Through magnetic force, it can be quickly organized, automatically adsorbed, and can be long or short, 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, once the wire body 100 is magnetized, the magnetism will not be reduced after long-term use. The combination of the protective layer 120 and the soft magnetic strip 40 is extruded into one piece and then inserted for the second time, so that the protective layer 120 can well protect the soft magnetic strip 40, and the soft magnetic strip 40 will not be worn out and lose magnetism, and will not lose the magnetic attraction function after long-term use. It is suitable for a variety of different work scenarios, easy to manage in production, and has a reasonable production cost.

[0030] The plurality of through holes 50 are respectively distributed around the wire core 20 , and a soft magnetic strip 40 is correspondingly inserted into each through hole 50 .

[0031] The molding of one side of the protective layer 30 helps the wire body 100 to be stably adsorbed to the first adsorption surface 310 , and the molding of the other side of the protective layer 30 helps the wire body 100 to be stably adsorbed to the second adsorption surface 320 .

[0032] The soft magnetic strip 40 is formed by integral extrusion; the protective layer 30 is also formed by integral extrusion.

[0033] The cross-sectional shape of the protective layer 30 is a lotus root core shape, and correspondingly, the cross-sectional shape of the soft magnetic strip 40 is one of an ellipse and a polygon.

[0034] Preferably, the ratio of the longitudinal cross-sectional area of ​​the protective layer 30 to the soft magnetic strip 40 is 6:1. The longitudinal cross-sectional area is the cross-sectional area obtained by radial cutting of the wire body 10; in addition, after a large number of experimental comparisons, when the ratio of the longitudinal cross-sectional area of ​​the protective layer 30 to the soft magnetic strip 40 is controlled to 6:1, the balance of magnetic force can be achieved, that is, it is convenient to unfold and straighten the wire body 100, and the magnetic force is sufficient during magnetic absorption.

[0035] The wire core 20 includes a metal conductor 210 and an insulating layer 220 integrally formed and wrapped around the metal conductor 210 . The protective layer 30 is integrally formed and wrapped around the insulating layer 220 .

[0036] A connector 60 is disposed at one end of the wire body 100 , and the connector 60 is an electrical plug.

[0037] In summary, in terms of structural implementation, the utility model reserves a plurality of through holes 50 in the protective layer 30, makes the protective layer 30 into a lotus core shape, and then inserts the soft magnetic strip 40 into the through hole 50 in a pulling manner, and a soft magnetic strip 40 is correspondingly introduced into each through hole 50, wherein the soft magnetic strip 40 and the protective layer 30 are extruded and formed as one piece respectively, and then combined into one piece by pulling and inserting; further, the assembled wire body 100 is overlapped and wound according to a predetermined style (such as: the middle part of the wire body 100 is folded into a spiral shape), and after the wire is wound, it is baked and shaped, and finally, the shaped wire body 10 is placed in a magnetizing device for magnetization, and after the magnetization is completed, a finished wire body 100 that can be automatically adsorbed, automatically stored, and automatically magnetically reeled back into a predetermined style is obtained;

[0038] This solution of achieving the magnetic absorption effect by pulling and inserting the soft magnetic strip 40 is highly feasible, has a simple and practical structure, is easy to manufacture, and can be applied to most types of wires and cables, especially small-sized wires with relatively lower magnetic requirements, such as data cables. Such small-sized wires have relatively lower magnetic requirements when being stored due to their own small mass, and since the cost of the soft magnetic strip 40 is higher than that of the protective layer 30, in order to optimize production costs, the protective layer 30 is made into a lotus core shape, and then pulled and inserted into the soft magnetic strip 40, which can not only achieve the magnetic absorption effect, but also reduce the material used for the soft magnetic strip 40 and reduce costs. At the same time, in this solution, any segment of the wire body 100 has magnetic force, can be absorbed and stored, and can automatically absorb and automatically reel. The fixed style can also realize the parallel adsorption of multiple lines. This solution is suitable for application to wires such as wires and cables, which can effectively solve and improve the problems of traditional wires that are easy to get tangled and entangled. Through magnetic force, it can be quickly sorted, automatically adsorbed, and can be long or short. There is no need to manually tie the wires and adjust the length for storage, which can bring great convenience to people's lives and greatly reduce the work pressure of power workers. In addition, once the wire body 100 is magnetized, the magnetism will not diminish after long-term use. The combination of the protective layer 120 and the soft magnetic strip 40 that are extruded as a whole and then inserted for the second time enables the protective layer 120 to protect the soft magnetic strip 40 very well, and the soft magnetic strip 40 will not wear out and lose magnetism, and will not lose the magnetic attraction function after long-term use. It is suitable for a variety of different work scenarios, easy to manage in production, and has a reasonable production cost.
