DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of the present application.

[0025] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a class, and are not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0026] Air-core inductor, also known as air-core inductor, is a non-magnetic core inductor. It is composed of winding and annular hollow structure, and the winding is usually composed of coil and the like. When the current through the winding changes, a changing magnetic field will be generated around it, which will generate an induced electromotive force in the coil, thereby hindering the change of current. Therefore, air-core inductor has been widely used in many fields, such as radio frequency power amplifier, etc., which has the functions of current blocking, tuning and frequency selection, etc.

[0027] The present application provides a winding device 100, please refer to Figure 1 and Figure 2The winding device 100 is used for winding the hollow inductor 200. Further, the winding device 100 can wind the wire bundle to form the winding of the hollow inductor 200.

[0028] The wire bundle can be an enameled wire, a bare metal wire, or the like. The enameled wire is provided with a surface insulation, and the enameled wire can be directly wound to form the hollow inductor 200. The bare metal wire can be a copper wire, an aluminum wire, or the like. The bare metal wire is wound to form the hollow inductor 200, and an insulation material can be filled between two adjacent turns to form the hollow inductor 200. Therefore, the embodiment is not limited to the material of the wire bundle, the number of turns, and the shape of the hollow inductor 200.

[0029] In the embodiment, please continue to refer to Figure 1 The winding device 100 can be a rigid member. For example, the winding device 100 can be a copper rod, a steel rod, a carbon fiber rod, or the like. The embodiment is not limited to the structure and specific material of the rigid member. Further, the rigidity of the winding device 100 can be higher than that of the wire bundle. The winding device 100 can easily wind the wire bundle to form the hollow inductor 200, and the winding device 100 itself does not deform, so that the winding device 100 can be repeatedly used.

[0030] Please continue to refer to Figure 1 The winding device 100 can include a plurality of winding portions 110. The number of the winding portions 110 is greater than or equal to 2, for example, 2, 5, 10, or 15, or the like. The circumferences of the plurality of winding portions 110 are different. The circumference can be the circumference of the outer surface of the winding portion 110. For example, for a cylindrical winding portion 110, the circumference is the length of one turn along the circumference of the winding portion 110. The winding portion 110 is used for winding the wire bundle to form the hollow inductor 200. For example, as shown in Figure 2 The wire bundle is wound around the axis of the winding portion 110, and the winding direction can be clockwise or counterclockwise. The plurality of winding portions 110 with different circumferences can wind the wire bundle to form hollow inductors 200 with different circumferences. Further, the operator can manufacture inductors with different circumferences and numbers of turns, so that the inductors meet the parameter requirements, for example, the inductance value of the manufactured hollow inductor 200 meets the requirements.

[0031] The plurality of winding portions 110 are sequentially connected end to end, and the plurality of winding portions 110 are integrated. The plurality of winding portions 110 can be integrated in one winding device 100. When different sizes of hollow inductors 200 need to be manufactured, the operator can wind the wire bundle on the winding portions with different circumferences, without the need to replace the winding rod with another diameter. The operation is simple, convenient for production, and improves the production efficiency. Compared with a plurality of winding rods, the winding device 100 has higher integration, smaller volume, and lighter weight, and is more convenient to carry and store, greatly saving the debugging time of the radio frequency power amplifier.

[0032] In the embodiment, please continue to refer toFigure 1 The winding device 100 has a first end 120 and a second end 130 away from each other. Further, the first end 120 and the second end 130 can be distributed along the length direction of the winding device 100. In the direction from the first end 120 to the second end 130, the circumferences of the plurality of winding portions 110 gradually increase, that is, the circumference of the winding device 100 changes gradiently along its own length direction. This arrangement can make it more convenient for the user to take out the completed hollow inductor 200, and avoid the hindrance of the winding portions 110 of different circumferences to the taking out of the hollow inductor 200. In addition, the gradually changing winding device 100 can also make it more convenient for the operator to find the winding portion 110 of the corresponding circumference, thereby improving the winding efficiency of the winding device 100.

[0033] In some other cases, in the direction from the first end 120 to the second end 130, the circumferences of the plurality of winding portions 110 gradually increase to a maximum value, and then gradually decrease from the maximum value. In other words, the winding device 100 can have a structure of small at both ends and large in the middle. This arrangement can meet the case of simultaneous operation of two operators, that is, the winding device 100 is fixedly arranged, and two operators operate at opposite ends of the winding device 100, thereby further improving the winding efficiency of the winding device 100.

[0034] In the embodiment, please continue to refer to Figure 2 The winding portion 110 can be cylindrical. This arrangement can be wound by the winding device 100 to obtain a cylindrical hollow inductor 200. The cylindrical hollow inductor 200 has a wider range of application, and it is an ideal shape in inductor theory, and its inductance value is more convenient to calculate. Further, the plurality of winding portions 110 can be cylindrical, and the diameters of the plurality of winding portions 110 are different, so as to wind the wire bundle to form hollow inductors 200 of different sizes in cylindrical shape.

[0035] In addition, in some other embodiments, the winding portion 110 can be rectangular and the like, and the embodiment does not limit the shape of the winding portion 110. Therefore, the plurality of winding portions 110 can be rectangular, and the side lengths of the plurality of winding portions 110 are different, so as to wind the wire bundle to form hollow inductors 200 of different sizes in rectangular shape, which will not be described in detail here.

[0036] In the embodiment, please refer to Figure 1The number of the winding portions 110 can be 2-20, such as 2, 5, 10, 15, 20, etc., and the embodiment is not limited. The number of the winding portions 110 should not be too large. Too many winding portions 110 can result in too long length of the winding device 100, which is inconvenient to carry. Or, under the same length, too many winding portions 110 can result in the length of each winding portion 110 being reduced, which affects the application range of the winding device 100. This setting can make the winding device 100 have an adaptive number of winding portions 110, and the portability and application range of the winding device 100 can be balanced to improve the use effect of the winding device 100.

[0037] In an embodiment, the diameter of the winding portion 110 can be 0.5-10 mm, such as 0.5 mm, 4 mm, 7 mm, or 10 mm, etc., and the embodiment is not limited. The diameter of the winding portion 110 should not be too small or too large. When the diameter of the winding portion 110 is too small, the strength of the winding portion 110 with too small diameter is limited, and it is prone to deformation or breakage. When the diameter of the winding portion 110 is too large, the volume of the winding portion 110 is too large, and the weight is too heavy. This setting can make the winding portion 110 have an appropriate diameter value, and the winding portion 110 with an appropriate diameter can ensure the structural strength of the winding device 100 and improve the winding success rate of the winding device 100.

[0038] Please refer to Figure 1 The diameter difference between the two adjacent winding portions 110 is 0.2-1 mm, such as 0.2 mm, 0.5 mm, 0.8 mm, or 1 mm, etc., and the embodiment is not limited. For example, as shown in Figure 3 , the diameter of one of the two adjacent winding portions 110 is d1, and the diameter of the other is d2, and the absolute value of the difference between d1 and d2 is 0.2-1 mm. The diameter difference between the two adjacent winding portions 110 should not be too large or too small. If the diameter difference between the two adjacent winding portions 110 is too large, the height difference between them is too large, which is prone to narrow space. It is difficult for the hand to enter the narrow space to wind the wire harness, which can shorten the effective winding range of a single winding portion 110 and reduce the application range of the winding device 100. If the diameter difference between the two adjacent winding portions 110 is too small, the size difference between them is not obvious, and the parameter value of the air-core inductor 200 wound by the two is too small. Instead, the winding device 100 also needs more complex production process and higher precision requirement, which will increase the manufacturing cost and bring weak effect. This setting can make the two adjacent winding portions 110 have an appropriate diameter difference, improve the use range of the winding device 100, reduce the manufacturing cost, and improve the use effect.

[0039] In some other cases, the length of the winding portion 110 can be 1-3 cm, such as 1 cm, 2 cm or 3 cm, and the embodiment is not limited in this regard. The length of the winding portion 110 should not be too large or too small, and the appropriate length of the winding portion 110 can improve the proportion of the effective working area and avoid the winding device 100 being too long or too short.

[0040] For example, referring to Figure 4 , the number of winding portions 110 can be 10, and the diameters of the 10 winding portions 110 are 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm and 5 mm, respectively. Further, the winding device 100 can include a first winding portion 161, a second winding portion 162, a third winding portion 163, a fourth winding portion 164, a fifth winding portion 165, a sixth winding portion 166, a seventh winding portion 167, an eighth winding portion 168, a ninth winding portion 169 and a tenth winding portion 170 distributed in the direction from the first end 120 to the second end 130, and the diameters of the first winding portion 161, the second winding portion 162, the third winding portion 163, the fourth winding portion 164, the fifth winding portion 165, the sixth winding portion 166, the seventh winding portion 167, the eighth winding portion 168, the ninth winding portion 169 and the tenth winding portion 170 are 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm and 5 mm, respectively. The diameter difference between the adjacent two winding portions 110 is constant, and the change level is clear, which facilitates the winding operation of the operator.

[0041] Preferably, referring to Figure 5 , the winding portion 110 is provided with an identification line 140, and the identification line 140 is used to show the length of the air-core inductor 200 wound on the winding portion 110. For example, the identification line 140 can be a plurality of length identifiers, such as scales, numerical values, etc., for example, the numerical values can be 0, 5 mm, 10 mm, etc. The plurality of length identifiers are distributed along the length direction of the winding portion 110. When winding the air-core inductor 200, the operator can clearly observe the length of the wound air-core inductor 200, ensure that the wound air-core inductor 200 meets the parameter requirements, and improve the controllability of the winding work.

[0042] It can be understood that the identification line 140 can enable the operator to observe the length value of the air core inductor 200 faster, so as to quickly calculate the inductance value of the air core inductor 200, so that the prepared air core inductor 200 can meet the preset requirement of the inductance value. For example, the inner diameter of the air core inductor 200 is equal to the outer diameter of the corresponding winding part 110, and the material of the wire bundle determines its own magnetic permeability. The identification line 140 can clearly show the length value of the air core inductor 200. The inductance value of the air core inductor 200 can be quickly calculated by the length value, the inner diameter, the magnetic permeability and the like of the air core inductor 200, thereby improving the controllability of the air core inductor 200.

[0043] In the embodiment, please refer to Figure 1 , one of the two adjacent winding parts 110 is nested and slides in the remaining one, so that the winding device 100 can be telescopic. As shown in Figure 6 , the winding device 100 can include a first winding part 161 and a second winding part 162 distributed in sequence along the direction from the first end 120 to the second end 130, and the diameter of the first winding part 161 is smaller than that of the second winding part 162. The second winding part 162 has a movable cavity 1621, and the first winding part 161 is slidingly fitted in the movable cavity 1621, so that the first winding part 161 and the second winding part 162 can be telescopic. When the winding device 100 works, the first winding part 161 extends out of the second winding part 162, and the first winding part 161 and the second winding part 162 can wind different sizes of air core inductors 200, respectively. When the winding device 100 is idle, the first winding part 161 extends into the second winding part 162, reducing the volume of the winding device 100, so that the winding device 100 is convenient to store and tends to be portable design. This setting can not only ensure the application range of the winding device 100 when working, but also reduce the volume of the winding device 100 when idle, so that the winding device 100 is convenient to carry.

[0044] It can be understood that the plurality of winding parts 110 of the winding device 100 can be telescopic, for example, the winding device 100 further includes a third winding part, a fourth winding part, and even more, and the plurality of winding parts are telescopic in sequence, further reducing the volume of the winding device 100 when idle, and significantly improving the portability of the winding device 100.

[0045] In the embodiment, please refer to Figure 2The winding section 110 may be provided with a fixing structure 150, which includes, but is not limited to, fixing holes, fixing slots, and snap-fits, etc., and this embodiment is not limited to these. The fixing structure 150 is used to selectively fix or release the end of the wire harness. For example, the fixing structure 150 can be a snap-fit ​​structure, allowing the operator to fix one end of the wire harness in the fixing structure 150. The operator holds the winding device 100 with one hand and drives the wire harness to wind with the other hand. After the wire harness is wound, the operator controls the fixing structure 150 to release the hollow inductor 200 and removes the hollow inductor 200. This setting can prevent the end of the wire harness from becoming loose, which could lead to winding failure, and can improve the tightness of the winding. In addition, when the winding device 100 is fixed to the operating table, fixing one end of the wire harness by the fixing structure 150 allows the operator to operate with one hand, improving the winding effect of the winding device 100.

[0046] In some other cases, the winding device 100 may also be equipped with a grip (not shown), located at either the first end 120 or the second end 130. The grip is ergonomic and improves the holding effect of the winding device 100. Combined with the fixing structure 150, the grip allows the operator to hold the device with one hand while winding the wire harness with the other. This eliminates the need for the operator to fix the winding device 100 before use, thus increasing its flexibility.

[0047] The technical solution adopted by this utility model can achieve the following beneficial effects: Multiple winding sections 110 with different circumferences are integrated into a single winding device 100. When it is necessary to manufacture hollow inductors 200 of different sizes, the operator can simply wind the wire harness around the winding sections of different circumferences without needing to switch to a winding device 100 of a different diameter. This operation is simple, facilitates production, and improves production efficiency. Compared to multiple winding devices 100, the winding device 100 of this embodiment has a higher degree of integration, smaller size, lighter weight, and is easier to carry and store.

[0048] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0049] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
