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 double-stranded wire material which can be absorbed and stored with magnetic properties. Background technology:

[0002] As society progresses, science and technology become more and more advanced. All of this is based on the application of electricity. Electricity has brought light and convenience to our lives. As the carrier of electricity, wires and cables are very common. Wherever there is electricity, wires and cables must exist. Their important position in life is self-evident. Wires and cables are a kind of metal product. They can be metal wires with smaller diameters or other shapes of materials. They are usually continuous lengths and very long. Wires and cables can be supplied in rolls, so they are also called coils or coils. Wires and cables are widely used, including but not limited to electrical, electronic, construction, transportation, machinery and other fields, used as connectors, supports or as raw materials.

[0003] Since wires and cables are very long, they are usually stacked and tangled together when carried, so they often need to be tied manually when used, which is very troublesome, unsightly, and takes up space. Traditional wires and cables are easy to get tangled and tangled, and are not easy to store. When using, the cables must be tied manually and the length adjusted according to the scene for use or storage management. When a single line or multiple lines are needed, cable ties are needed to organize the lines, which easily makes the work scene more messy. The messy wires and cables not only occupy a larger storage space, but in serious cases, they may even cause safety problems.

[0004] In order to prevent the wires from getting tangled together, people wrap the wires around poles, which makes it easier for people to use. Since manual wire winding and storage is not only slow, but also often results in uneven winding during the storage process, people usually use wire storage devices to wrap the wires around poles to reduce the storage cost and transportation difficulty of wires and cables.

[0005] For example, the Chinese utility model patent with patent announcement number CN209038772U discloses a wire storage device for preventing electric wires from being entangled, which includes: a bottom rod, a bearing, a support rod and a fixed rod. Two fixed rods are provided, and a fixed rod is clamped between the bottom rods. A support rod is welded in the middle of the top of the bottom rod, and a bearing is welded on the top of the support rod. A butt plug is welded on the inner ring of the bearing. Among them, the fixed rod can fix the two bottom rods together, so that the butt plug and the active rod cooperate to clamp the wire take-up rod. After the wire is taken up, the wire take-up rod can be removed from between the butt plug and the active rod, and a new wire take-up rod can be replaced for continued use. It has the advantages of simple structure and convenient use.

[0006] However, the existing wire storage device clamps the wire take-up rod by cooperating with the docking bolt and the active rod, thereby making the wire take-up rod detachable. Such a structure is usually more suitable for storing large coils of wire and is often used for sorting wire coils before leaving the factory. It is difficult to neatly store shorter wires after cutting and segmenting, and is not convenient to use.

[0007] In view of this, the inventor proposes the following technical solution. Utility model content:

[0008] The utility model aims to overcome the shortcomings of the prior art and provide a double-stranded wire material that can be absorbed and stored with magnetic properties.

[0009] In order to solve the above technical problems, the utility model adopts the following technical solution: a double-stranded magnetically adsorbable wire, including a wire body, characterized in that:

[0010] The wire body includes a first wire core group, a second wire core group, a soft magnetic body arranged between the first wire core group and the second wire core group, and a protective layer, wherein the protective layer is wrapped around the periphery of the soft magnetic body, the first wire core group and the second wire core group;

[0011] A first magnetic attraction portion and a second magnetic attraction portion are respectively protruded from two sides of the soft magnetic body.

[0012] Furthermore, in the above technical solution, the cross-sectional shape of the soft magnetic body is an I-shape, and correspondingly, the first wire core group and the second wire core group both have cross-sectional shapes that are compatible with the soft magnetic body.

[0013] Furthermore, in the above technical solution, the ratio of the longitudinal cross-sectional area of ​​the protective layer to the soft magnetic body is 5:1.

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

[0015] Furthermore, in the above technical solution, a avoidance hole is formed in the protective layer, and the first wire core group, the second wire core group and the soft magnetic body are correspondingly inserted into the avoidance hole.

[0016] Furthermore, in the above technical solution, one side of the protective layer is molded to help the wire body to adsorb stably to the first adsorption surface, and the first adsorption surface is close to the first magnetic attraction part; the other side of the protective layer is molded to help the wire body to adsorb stably to the second adsorption surface, and the second adsorption surface is close to the second magnetic attraction part.

[0017] Furthermore, in the above technical solution, the protective layer forms a first avoidance portion thinner than the protective layer at the first adsorption surface; and the protective layer forms a second avoidance portion thinner than the protective layer at the second adsorption surface.

[0018] Furthermore, in the above technical solution, the first wire core group includes a first metal conductor and a first insulating layer integrally formed and wrapped around the first metal conductor, and the second wire core group includes a second metal conductor and a second insulating layer integrally formed and wrapped around the second metal conductor.

[0019] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: in the utility model, by reserving an avoidance hole on the protective layer, the soft magnet, the first wire core group and the second wire core group are pulled into the avoidance hole, wherein the soft magnet is located between the first wire core group and the second wire core group, and separates the first wire core group from the second wire core group; compared with most of the existing wires on the market, the wire winding classification at the factory is omitted, and any segment of the wire body has magnetic force, can be adsorbed and stored, and can automatically be magnetically attracted and automatically rolled back into a predetermined style. Therefore, for wires with shorter lengths after cutting and segmenting, they can still be automatically magnetically attracted and automatically rolled back into a predetermined style, without the need to use wire storage equipment, and are highly practical.

[0020] This technical solution of separating the first wire core group and the second wire core group by a soft magnet is particularly suitable for wires whose cores are divided into multiple strands. It can not only achieve the magnetic absorption effect, but also has a simple and practical structure and is easy to manage. At the same time, this solution can effectively solve and improve the problems that traditional wires are easy to get tangled and entangled, difficult to organize and not portable. Through magnetic force, they can be quickly organized, automatically adsorbed, and can be long or short. The multi-wire 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, once the wire body is magnetized, the magnetism will not be reduced after long-term use. Moreover, the protective layer is made of fireproof and moisture-proof material. In terms of structure, the protective layer is wrapped around the outer periphery of the soft magnet, the first wire core group and the second wire core group, which can maximize the protective effect of the protective layer, protect the soft magnet from being worn and demagnetized, and will not lose the magnetic absorption function after long-term use. It is suitable for a variety of different work scenes such as outdoor, damp, and underground, with a wide range of uses and a long service life. Description of the drawings:

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

[0026] See Figures 1 to 4 As shown, a double-stranded magnetically absorbable wire includes a wire body 10, which is characterized by:

[0027] The wire body 10 includes a first wire core group 210, a second wire core group 220, a soft magnetic body 30 disposed between the first wire core group 210 and the second wire core group 220, and a protective layer 40, wherein the protective layer 40 is wrapped around the periphery of the soft magnetic body 30, the first wire core group 210 and the second wire core group 220;

[0028] A first magnetic attraction portion 310 and a second magnetic attraction portion 320 are respectively protruded from two sides of the soft magnetic body 30 .

[0029] In terms of structural implementation, the utility model reserves an avoidance hole 410 on the protective layer 40, so that the soft magnetic body 30, the first wire core group 210 and the second wire core group 220 are pulled into the avoidance hole 410, wherein the soft magnetic body 30 is located between the first wire core group 210 and the second wire core group 220, and the first wire core group 210 and the second wire core group 220 are separated; further, the assembled wire body 10 is wound according to a predetermined pattern (such as: the middle part of the wire body 10 is overlapped in a spiral shape), and after winding, it is baked and shaped, and finally Finally, the shaped wire body 10 is placed in the magnetizing equipment for magnetization. After the magnetization is completed, the finished wire body 10 which can be automatically adsorbed, automatically stored, and automatically magnetically wound back into a predetermined style is obtained. Compared with most of the existing wires on the market, the wire winding classification at the factory is omitted, and any segment of the wire body 10 has magnetic force and can be adsorbed and stored, and can be automatically magnetically attracted and automatically wound back into a predetermined style. Therefore, for the wire with a shorter length after cutting and segmenting, it can still be automatically magnetically attracted and automatically wound back into a predetermined style, without the need to use wire storage equipment, and the practicability is strong.

[0030] This technical solution of separating the first wire core group 210 and the second wire core group 220 by the soft magnet 30 is particularly suitable for wires whose cores are divided into multiple strands. It can not only achieve the magnetic absorption effect, but also has a simple and practical structure and is convenient for production management. At the same time, this solution can effectively solve and improve the problems that traditional wires are easy to get tangled, entangled, difficult to organize and not portable. Through magnetic force, they can be quickly organized, automatically adsorbed, and can be long or short. The multi-wire integration, detachable and combinable method can adapt to various work scenes, without manual wire tying and length adjustment for storage, which can bring great benefits to people's lives. It is convenient and can greatly reduce the work pressure of power workers. In addition, once the wire body 10 is magnetized, the magnetism will not diminish after long-term use. Moreover, the protective layer 40 is made of fire-proof and moisture-proof material. Structurally, the protective layer 40 is wrapped around the periphery of the soft magnetic body 30, the first wire core group 210 and the second wire core group 220, which can maximize the protective effect of the protective layer 40 and protect the soft magnetic body 30 from being worn and demagnetized. The magnetic attraction function will not be lost after long-term use. It is suitable for various different working scenes such as outdoor, damp, underground, etc. It has a wide range of use and a long service life.

[0031] The cross-sectional shape of the soft magnetic body 30 is an I-shaped shape. Correspondingly, the first wire core group 210 and the second wire core group 220 both have cross-sectional shapes that match the soft magnetic body 30 .

[0032] Preferably, the ratio of the longitudinal cross-sectional area of ​​the protective layer 40 to the soft magnetic body 30 is 5:1. 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 40 to the soft magnetic body 30 is controlled to 5:1, sufficient magnetic force can be ensured.

[0033] The protective layer 40 is formed by integral extrusion; the soft magnetic body 30 is formed by integral extrusion.

[0034] The protective layer 40 is formed with an avoidance hole 410 , and the first wire core group 210 , the second wire core group 220 and the soft magnetic body 30 are correspondingly arranged in the avoidance hole 410 .

[0035] The molding of one side of the protective layer 40 helps the wire body 10 to be stably adsorbed on the first adsorption surface 60, and the first adsorption surface 60 is located on a side close to the first magnetic attraction portion 310; the molding of the other side of the protective layer 40 helps the wire body 10 to be stably adsorbed on the second adsorption surface 70, and the second adsorption surface 70 is located on a side close to the second magnetic attraction portion 320.

[0036] The protective layer 40 has a first avoidance portion 610 formed at the first adsorption surface 60 , which is thinner than the protective layer 40 ; the protective layer 40 has a second avoidance portion 720 formed at the second adsorption surface 70 , which is thinner than the protective layer 40 .

[0037] The first wire core group 210 includes a first metal conductor 211 and a first insulating layer 212 integrally formed and wrapped around the outside of the first metal conductor 211, and the second wire core group 220 includes a second metal conductor 221 and a second insulating layer 222 integrally formed and wrapped around the outside of the second metal conductor 221. During production, the soft magnetic body 30 is first extruded into an integral form, and then the first wire core group 210 and the second wire core group 220 are respectively pasted on both sides of the soft magnetic body 30, wherein the first insulating layer 212 and the second insulating layer 222 have a cross-sectional shape adapted to the soft magnetic body 30, and after pasting, they are correspondingly pulled into the avoidance hole 410 on the protective layer 40, and the assembly of the wire body 10 is completed.

[0038] A connector 80 is disposed at one end of the wire body 10 .

[0039] In summary, in terms of structural implementation, the utility model reserves an avoidance hole 410 on the protective layer 40, so that the soft magnetic body 30, the first wire core group 210 and the second wire core group 220 are pulled into the avoidance hole 410, wherein the soft magnetic body 30 is located between the first wire core group 210 and the second wire core group 220, and the first wire core group 210 and the second wire core group 220 are separated; further, the assembled wire body 10 is wound according to a predetermined pattern (such as: the middle part of the wire body 10 is overlapped in a spiral shape), and after winding, it is baked for a predetermined time. Finally, 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 reeled into a predetermined style is obtained. Compared with most of the existing wires on the market, the wire winding classification at the factory is omitted, and any segment of the wire body 10 has magnetic force and can be adsorbed and stored, and can be automatically magnetically attracted and automatically reeled into a predetermined style. Therefore, for wires with shorter lengths after cutting and segmenting, they can still be automatically magnetically attracted and automatically reeled into a predetermined style, without the need to use wire storage equipment, and the practicability is strong.

[0040] This technical solution of separating the first wire core group 210 and the second wire core group 220 by the soft magnet 30 is particularly suitable for wires whose cores are divided into multiple strands. It can not only achieve the magnetic absorption effect, but also has a simple and practical structure and is convenient for production management. At the same time, this solution can effectively solve and improve the problems that traditional wires are easy to get tangled, entangled, difficult to organize and not portable. Through magnetic force, they can be quickly organized, automatically adsorbed, and can be long or short. The multi-wire integration, detachable and combinable method can adapt to various work scenes, without manual wire tying and length adjustment for storage, which can bring great benefits to people's lives.
