Description

Technical Field

[0001] The present invention relates to the technical field of winding components, and in particular to a winding component and a method for manufacturing the winding component. Background Art

[0002] Winding components are used in various electronic products for various purposes, for example, in on-board chargers for electric vehicles (EVs), plug-in hybrid vehicles (PHVs), or commuter (vehicles), or as transformers such as leakage transformers in LLC circuits.

[0003] On the one hand, with the development of technology, the requirements for miniaturization and integration of winding components are getting higher and higher. On the other hand, according to actual needs, sometimes a winding component includes multiple coils, and multiple conductors need to be led out from the multiple coils and connected to the terminals. In the prior art, there is usually an inconvenience in connecting the conductors to the terminals, which causes the connection process in the manufacturing process to be complicated, thereby reducing the production efficiency.

[0004] In addition, when the conductor led out from the coil is connected to the terminal, there is a risk of contacting other coils. Although in the prior art, there are technical means to sleeve the conductor led out from the coil in order to avoid the above risks. However, since the sleeve has a certain volume, the volume of the winding assembly will increase, and since the operation process of sleeve is complicated, the production efficiency will decrease and the mass production cost will increase. In addition, in the prior art, there is also a method of leading the conductor led out from the coil along the opposite sides so that the conductors do not contact each other and the conductors do not contact other coils.

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Features modified by "first", "second", etc. in the description and claims of the present invention may explicitly or implicitly include one or more features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] It is known that "winding portion" may refer to electronic components containing coils, such as inductors and transformers. In addition, "winding portion" may also refer to a magnetic component assembled from one or more coils and corresponding core components. According to the function that the "winding portion" needs to achieve, the "winding portion" may also include a core portion, which may be an iron core, a magnetic core, etc. Since the present invention is based on the situation where the winding component is connected to the terminal and then installed in the circuit. Therefore, the "winding assembly" in the present invention may refer to a winding portion including a terminal. Since the present invention adopts the technical means of assembling the winding portion, the base portion and the terminal, the "winding assembly" in the present invention may also refer to the assembly of the base portion, the terminal and the winding portion of the embodiment of the present invention.

[0040] It is known that the existing terminals are currently commonly used conductive parts that connect electronic components to external conductors (or circuits), and they can have various shapes. In the embodiments of the present invention, the shape and constituent materials of the terminals are not limited, as long as they are conductive. The "conductor" in the present invention refers to the conductor that constitutes the coil, which includes a wire with a circular or approximately circular cross-section, a flat wire wire that constitutes a flat coil, or a conductive approximately annular sheet (plate), etc., as long as it can constitute a coil, the present invention does not limit its shape or material.

[0041] Refer to the following Figure 1 and Figure 2 The winding assembly according to the embodiment of the present invention is described.

[0042] Figure 1 1 is a schematic diagram of the structure of a winding assembly according to an embodiment of the present invention.

[0043] Figure 2 2 is a schematic diagram of the structure of a winding assembly according to an embodiment of the present invention, wherein the winding assembly is removed. Figure 1 Schematic diagram of the core 6 and the base 4 of the winding assembly.

[0044] like Figure 1 and Figure 2As shown, in one embodiment of the present invention, the winding assembly includes: a winding part 1, including a coil 2, from which a conductor 3 is led; a base part 4, mounted on the winding part 1; and a terminal 5, mounted on the base part 4, and the terminal 5 is mounted on the side of the base part 4 opposite to the winding part 1, and the conductor 3 is led from the coil 2 along the thickness direction of the base part 4 on the side of the base part 4 opposite to the winding part 1 and connected to the terminal 5. As described above, since the terminal 5 and the conductor 3 are both arranged on the side of the base part 4 opposite to the winding part 1, compared with the prior art in which the terminal and the conductor are arranged on the side of the base part, the miniaturization of the winding assembly can be achieved, and the connection process in the manufacturing process can be simplified. Optionally, when the conductor 3 includes a plurality of conductors, the conductors that need to be interconnected among the plurality of conductors can be connected to the same terminal, and preferably the terminal includes a plate-shaped portion extending along the plane where the base part 4 is located, and the conductor that needs to be interconnected is connected to the plate-shaped portion of the terminal extending along the plane where the base part 4 is located, so that the conductors connected to the terminal are interconnected with each other.

[0045] Optionally, during the process of installing the terminal 5 and leading out the conductor 3 , the projections of the terminal 5 and the conductor 3 in a direction perpendicular to the plane where the base portion 4 is located can be located within the range of the base portion 4 .

[0046] Optionally, the winding portion 1 includes a coil 2 and a core 6. In other embodiments, the winding portion 1 may not include the core 6 depending on the function to be achieved, and the present invention is not limited thereto. The conductor 3 led out from the coil 2 may be provided separately from the coil 2, or may be integrally formed with the coil 2, as long as the conductor 3 is conductive and can be connected between the coil 2 and the terminal 5. The conductor 3 may be formed of any conductive material and may have any shape. Figure 2 As shown, the conductor 3 on the left side of the figure is a sheet integrally formed with the coil 2 on the left side, and the conductor 3 on the right side is a linear conductor led out from the coil 2 on the right side. In the present invention, the base portion 4 is a roughly plate-shaped component that can be installed on one side of the winding portion 1. The base portion can be made of insulating materials such as resin and plastic, but the present invention is not limited to this. By installing the terminal 5 on the base portion 4 and mounting the base portion 4 on the winding portion 1, the terminal 5, the base portion 4 and the winding portion 1 can be assembled into the winding assembly of the present invention. Through such an assembly, the winding assembly can be packaged, which can be beneficial to the miniaturization of electronic components and improve the efficiency of circuit assembly. The terminal 5 is installed on the side of the base portion 4 opposite to the winding portion 1. After the conductor 3 is led out from the coil 2, it extends along the thickness direction of the base portion 4 and is connected to the terminal 5 on the side of the base portion 4 opposite to the winding portion 1.

[0047] Alternatively, if Figure 2As shown, the conductor 3 on the left is vertically drawn out from the coil and extends from one side of the base 4 to the opposite side, and is connected to the corresponding terminal 5. Optionally, in the direction perpendicular to the plane where the base 4 is located, the projection area of ​​the conductor 3 on the left does not exceed the projection area of ​​the coil 2 on the left, so that when it is connected to the base 4, the projection area of ​​the conductor 3 on the left does not exceed the projection area of ​​the coil 2 on the left. Figure 2 When the other winding parts or other coils on the right are assembled to form a winding assembly, the conductor 3 led out from the coil 2 on the left will not have the risk of contacting the other coils and conductors on the right. Since the above operation is achieved without the help of other components such as insulating sleeves, it is helpful to miniaturize the winding assembly. At the same time, due to the simple operation, the production efficiency of the winding assembly can be improved and the mass production cost can be reduced.

[0048] In order to miniaturize the winding assembly, it is preferred that the projection area of ​​the base 4 and the projection area of ​​the winding 1 in the vertical direction of the base 4 be substantially equal. Figure 1 and Figure 2 As shown, in the vertical direction of the base part 4, the projection area of ​​the conductor 3 does not exceed the range of the projection area of ​​the base part 4. Since the terminal 5 is installed on the side of the base part 4 opposite to the winding part 1, the projections of the conductor 3 and the terminal 5 in the direction perpendicular to the plane where the base part 4 is located can be optionally located within the range of the base part 4. The above structure can avoid the increase of the projection area of ​​the winding assembly in the direction perpendicular to the plane where the base part 4 is located, which is conducive to the miniaturization of the winding assembly.

[0049] Optionally, the axial direction of the coil 2 is parallel to the plane where the base portion 4 is located. This enables the conductor 3 to reach the base portion 4 installed on one side of the winding portion 1 at the shortest distance. Moreover, the shorter the path that the conductor 3 takes from the coil 2 to the terminal 5, the lower the risk of contacting other coils or contacting conductors led out from other coils, but the present invention is not limited to this.

[0050] Optionally, the terminal 5 can be installed approximately vertically on the side of the base portion 4 opposite to the winding portion 1. By installing the terminal 5 approximately vertically to the base portion 4, the projection of the terminal 5 in the direction perpendicular to the plane where the base portion 4 is located can be minimized, which is conducive to the miniaturization of the winding assembly, but the present invention is not limited to this, as long as the projection of the terminal 5 in the direction perpendicular to the plane where the base portion 4 is located is within the range of the projection area of ​​the base portion 4.

[0051] Optionally, the base portion 4 is integrally formed.

[0052] In addition, in the embodiment of the present invention, the connection between the terminal and the conductor only needs to be electrically connected, and preferably the two are welded or fused so that the two are fixed relative to each other while being conductive, but the present invention is not limited thereto. Optionally, the corresponding terminals and conductors are welded or fused uniformly after the winding assembly is assembled.

[0053] Please refer to the attached Figures 3 to 7 A winding assembly according to another embodiment of the present invention will be described.

[0054] Figure 3 is one of the structural schematic diagrams of a winding assembly according to another embodiment of the present invention. Figure 4 is a second structural schematic diagram of a winding assembly according to another embodiment of the present invention, which is to remove Figure 3 Schematic diagram of the core 6 and the base 4 of the winding assembly. Figure 5 yes Figure 1 Schematic diagram of the structure of the first coil and the second coil. Figure 6 It is a schematic structural diagram of a pedestal portion in an embodiment of the present invention. Figure 7 It is a partially enlarged schematic diagram of the structure of the base portion in the embodiment of the present invention.

[0055] like Figure 3 and Figure 4 As shown, the coil 2 includes a first coil 2a and a second coil 2b, at least one first conductor 3a is led out from the first coil 2a, and at least one second conductor 3b is led out from the second coil 2b; the terminal 5 includes a first terminal 5a and a second terminal 5b; and one of the first conductor 3a and the second conductor 3b is led out from the first coil 2a and the second coil 2b along the thickness direction of the base part 4 on the side opposite to the winding part 1 and connected to the first terminal 5a and the second terminal 5b, respectively, without contacting the other. As described above, since the first terminal 5a and the second terminal 5b and the first conductor 3a and the second conductor 3b are all arranged on the side opposite to the winding part 1 of the base part 4, compared with the prior art in which the terminals and conductors are arranged on the side of the base part, the winding assembly can be miniaturized and the connection process in the manufacturing process can be simplified.

[0056] like Figure 5 As shown, the first coil 2a is composed of a bobbin and a conductor for winding the coil, and the second coil 2b is composed of two sheet-shaped conductors sandwiching one insulating sheet. Figure 4 The winding portion in the embodiment is composed of three first coils 2a and four second coils 2b and Figure 3 The core 6 is composed of three first coils 2a and four second coils 2b arranged in a mutually spaced manner.

[0057] Alternatively, if Figure 6 As shown, the base 4 includes an opening 7, and the second conductor 3b is led out from the second coil 2b along the thickness direction of the base 4 on the side opposite to the winding part 1 through the opening 7 and connected to the second terminal 5b.

[0058] like Figure 4As shown, the conductor sheet constituting each second coil 2b is in the shape of having two flanges, which are equivalent to the second conductor 3b led out from the coil as described above, and the two conductors of each second coil 2b respectively pass through the opening 7 of the base 4 along the thickness direction of the base 4 (in this embodiment, the direction perpendicular to the base 4) and are respectively connected to the corresponding two second terminals 5b. In the direction perpendicular to the plane where the base 4 is located, since the projection area of ​​the second conductor 3b does not exceed the scope of the projection area of ​​the second coil 2b, when it is assembled with the first coil 2a, there is no risk of the second conductor 3b contacting the first coil 2a.

[0059] Alternatively, if Figure 6 As shown, the base portion 4 further includes a conductor guide portion 8 for collecting and guiding the first conductors 3 a so that the first conductors 3 a extend within the range of the base portion 4 and are connected to the first terminal 5 a .

[0060] like Figure 7 As shown, the conductor guide portion 8 includes a collection portion 8a and an extension portion 8b. After each first conductor 3a is led out from the first coil 2a, it passes through the base portion 4 in the thickness direction to the opposite side and is collected at the collection portion 8a. In this process, the first conductor 3a is in a straightened state. After reaching the collection portion 8a, it is guided to extend along the extension portion 8b and reach the first terminal 5a. Since the base portion 4 has a certain thickness, the collection portion 8a has a certain height difference relative to the lead-out point of the first conductor 3a from the first coil 2a. When each first conductor 3a is led out from the first coil 2a to the collection portion 8a, it extends along the thickness direction of the base portion 4 as a whole. By adjusting the height of the base portion 4 relative to the winding portion 1 and the position of the collection portion 8a relative to the winding portion 1, the first conductor 3a can be led out from the first coil 2a to the collection portion 8a. The height of the winding portion 1 and the position of the collection portion 8a relative to the winding portion 1 can prevent the first conductor 3a from contacting other coils (the second coil 2b in this embodiment) on the path from the first coil 2a to the collection portion 8a. In this embodiment, since the first coil is formed by winding the first conductor on a bobbin, the bobbin can be an insulating material such as resin. By making the outer diameter of the cross section of the bobbin larger than or equal to the outer diameter of the second coil 2 b , the risk of the first conductor 3 a contacting the second coil 2 b can be further reduced.

[0061] As described above, the first conductor 3a and the second conductor 3b are led out from the corresponding coil of the winding part 1 and pass through the pedestal part in the thickness direction of the pedestal part, and the projection of the extension path in the direction perpendicular to the plane where the pedestal part 4 is located is within the range of the pedestal part. Therefore, when the first conductor 3a is not in contact with the second coil 2b and the second conductor 3b is not in contact with the first coil 2a, the projection area of ​​the winding assembly in the direction perpendicular to the plane where the pedestal part 4 is located is not increased, which is conducive to the miniaturization of the winding assembly. In addition, since the above operation is not achieved with the help of other components such as insulating sleeves, it further contributes to the miniaturization of the winding assembly and is easy to operate. Since the connection part between the first conductor 3a led out from the first coil 2a and the first terminal 5a and the connection part between the second conductor 3b led out from the second coil 2b and the second terminal 5b are on the same side of the pedestal part 4, the connection process is easy, which can improve the production efficiency of the winding assembly and reduce the mass production cost.

[0062] Alternatively, if Figure 7 As shown, the base portion 4 further includes a partition wall 9, which is configured as a wall-like structure protruding from the base portion 4 along the thickness direction of the base portion 4 and is used to separate the first conductor 3a and the second conductor 3b. Figure 7 , Figure 3 and Figure 4 As shown, if the partition wall 9 protrudes from the side of the base part 4 close to the winding part 1, the partition wall 9 can separate the first conductor 3a and the second conductor 3b led out from the winding part 1. If the partition wall 9 protrudes from the opposite side of the side of the base part 4 close to the winding part 1, the partition wall 9 can separate the first conductor 3a in the opening 7 passing through the base part 4 and the second conductor 3b located in the conductor guide part. If the partition wall includes both a portion protruding from the side of the base part close to the winding part 1 and a portion protruding from the opposite side of the side of the base part 4 close to the winding part 1, it can have both of the above-mentioned two separation functions, and the present invention is not limited to this. Optionally, the partition wall 9 can be integrally formed with the base part 4, but the present invention is not limited to this.

[0063] Combine the following Figures 1 to 8 A method for manufacturing a winding assembly according to an embodiment of the present invention is described.

[0064] Figure 8 is a flow chart of a method for manufacturing a winding assembly according to an embodiment of the present invention.

[0065] Reference Figures 1-2 and Figure 8In an embodiment of the present invention, a method for manufacturing a winding assembly may include: step S801, mounting the base portion 4 on the winding portion 1. Specifically, when the base portion 4 is mounted on one side of the winding portion 1, the two can be fixed by various means such as snapping. The positional relationship between the winding portion 1 and the base portion 4 can be that the winding portion 1 is on top or other relationships, which is not limited by the present invention; step S803, installing the terminal 5 on the side of the base portion 4 opposite to the winding portion 1. Optionally, the base portion 4 includes a terminal mounting portion for mounting the terminal 5. The present invention There is no limitation on this; and step S805, leading out the conductor 3 from the coil 2 along the thickness direction of the base portion 4 on the side of the base portion 4 opposite to the winding portion 1 and connecting it to the terminal 5. Optionally, the base portion 4 may include an opening portion 7 whose size and shape are set to allow the terminal 5 and the conductor 3 to easily pass through. When the base portion 4 is mounted on the winding portion 1, the conductor 3 led out from the winding portion 1 passes through the opening portion 7 of the base portion 4 to reach the other side of the base portion 4, and then, the conductor 3 is connected to the terminal 5. The connection means is as described above, which may be welding or melting, etc.

[0066] In an optional embodiment, the method for manufacturing the winding assembly may further include: making the projections of the conductor 3 and the terminal 5 in the direction perpendicular to the plane where the base 4 is located both located within the range of the base 4. Specifically, since the terminal 5 is installed on the side of the base 4 opposite to the winding part 1, the conductor 3 is led out from the coil 2, extends along the thickness direction of the base 4, and is connected to the terminal 5 on the side of the base 4 opposite to the winding part 1. According to the path of the conductor 3, it can be deduced that the projection area of ​​the conductor 3 in the direction perpendicular to the plane where the base 4 is located will not exceed the range of the projection area of ​​the base 4. Therefore, it is only necessary to limit the projection of the terminal 5 in the direction perpendicular to the plane where the base 4 is located. Since the terminal 5 is installed on one side of the base 4, it is only necessary to limit the positional relationship of the terminal 5 relative to the base 4 when it is installed. When the terminal 5 is located within the range of the base 4 as a whole, it is preferred that the terminal 5 is vertically installed on the side of the base 4 opposite to the winding part 1, but the present invention is not limited thereto.

[0067] According to the manufacturing method of the above-mentioned winding assembly, by making the projections of the terminal 5 and the conductor 3 in a direction perpendicular to the plane where the base portion 4 is located within the range of the base portion 4 (which can be further limited to within the range of the winding portion 1), it is possible to prevent the conductor from contacting other coils or conductors led out from other coils when the winding portion is assembled with other winding portions or other coils to form a winding assembly. Under such a premise, since the above-mentioned operation does not require the aid of other components such as an insulating sleeve to be implemented, it is helpful to miniaturize the winding assembly. At the same time, due to the simple operation, the production efficiency of the winding assembly can be improved and the mass production cost can be reduced.

[0068] In another optional embodiment, the coil 2 includes a first coil and a second coil, at least one first conductor is led out from the first coil, and at least one second conductor is led out from the second coil, the terminal 5 includes a first terminal and a second terminal, and the manufacturing method of the winding assembly also includes the following steps: when one of the first conductor and the second conductor is not in contact with the other, the first conductor and the second conductor are respectively led out from the first coil and the second coil along the thickness direction of the base portion 4 on the side opposite to the winding portion 1 and connected to the first terminal and the second terminal. Specifically, the base portion 4 may include an opening portion 6 whose size and shape are set to allow the first terminal and the second terminal and the first conductor and the second conductor to easily pass through. Since the first coil and the second coil are constructed as a structure in which the conductors led out from the coils extend to one side, while the base portion 4 is mounted on one side of the winding portion 1 (i.e., the side on which the conductors extend out from the coils), the first conductor led out from the first coil and the second conductor led out from the second coil are passed through the opening portion 6 of the base portion 4 in the thickness direction to the other side of the base portion 4 while one of the first conductor and the second conductor is not in contact with the other, and then the first conductor and the second conductor are connected to the first terminal and the second terminal, respectively.

[0069] Reference Figures 3 to 7 In an optional embodiment, the coil 2 includes a first coil 2a and a second coil 2b, at least one first conductor 3a is led out from the first coil 2a, and at least one second conductor 3b is led out from the second coil 2b, the terminal 5 includes a first terminal 5a and a second terminal 5b, the base portion 4 includes an opening portion 7 and a conductor guide portion 8, and the manufacturing method of the winding assembly also includes the following steps: the second conductor 3b is led out from the second coil 2b through the opening portion 7 along the thickness direction of the base portion 4 on the side of the base portion 4 opposite to the winding portion 1 and connected to the second terminal 5b; and the first conductor 3a is gathered and guided by the conductor guide portion 8 so that the first conductor 3a extends within the range of the base portion 4 and is connected to the first terminal 5a. In an optional embodiment, the first coil 2a and the second coil 2b are as follows Figure 5 The structure shown in the figure is specifically described as described above. When the base part 4 is mounted on the winding part 1, since the base part 4 includes the opening part 7 and the second coil 2b is configured such that each coil has two flanges (equivalent to the second conductor 3b led out from the second coil 2b), at this time, the second conductor 3b passes through the opening part 7 and reaches the other side of the base part 4 and is connected to the second terminal 5b. The projection of the extension path of each second conductor 3b in the direction perpendicular to the plane where the base part 4 is located will not exceed the range of the projection of each second coil 2b.

[0070] In addition, the base 4 also includes a conductor guide 8, and the conductor guide 8 includes a collection portion 8a and an extension portion 8b. After each first conductor 3a is led out from the first coil 2a, it passes through the base 4 in the thickness direction to the opposite side, is gathered at the collection portion 8a, and then is guided to extend along the extension portion 8b. By adjusting the height of the base 4 relative to the winding portion 1 and the position of the collection portion relative to the winding portion 1, the first conductor 3a can be led out from the first coil 2a and reach The collection portion 8a does not contact the second coil 2b on the path. Please refer to the above description for details, and the present invention will not repeat them.

[0071] When the first conductor 3a is not in contact with the second coil 2b and the second conductor 3b is not in contact with the first coil 2a, the projection area of ​​the winding assembly in the direction perpendicular to the plane where the base portion 4 is located is not increased, which is conducive to the miniaturization of the winding assembly. In addition, since the above operation is not achieved with the help of other components such as the insulating sleeve, it helps to further miniaturize the winding assembly and simplifies the manufacturing process, thereby improving the production efficiency of the winding assembly and reducing the mass production cost.

[0072] In summary, the present invention provides a winding assembly and a method for manufacturing the winding assembly, wherein the winding assembly is structured such that the terminal is mounted on the side of the base portion opposite to the winding portion, and the conductor is led out from the coil along the thickness direction of the base portion on the side of the base portion opposite to the winding portion and connected to the corresponding terminal, thereby further miniaturizing the components and simplifying the connection process in the manufacturing process, thereby improving production efficiency. In addition, the conductors can be effectively insulated from each other and from other coils.
