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] With the development of technology, the requirements for the miniaturization and integration of winding components are getting higher and higher. There are currently two mainstream installation methods when installing multiple winding components, namely, combined installation by flying wire method and bolt method. In order to install the winding components on the circuit board, winding components with terminals are now commonly used. In other words, the terminals need to be electrically connected to the conductors of the winding components in the winding assembly. However, in actual operation, since the conductor (for example, cable) is flexible, it is difficult to fix it relative to the terminal, and the conductor is prone to falling off and loosening.

[0003] For example, in Patent Document 1, when fixing the terminal to the conductor of the winding component, the terminal needs to be wrapped with coil insulation paper, which has the problems of complex process and low production efficiency.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] It is known that "winding component" refers to an electronic component containing windings, including inductors, transformers, etc. In addition, a "winding component" may also be an integrated electronic device containing multiple windings. Since the present invention is based on the situation where a winding component is connected to a terminal and then installed on a circuit board. Therefore, the "winding assembly" in the present invention may refer to a winding component including a terminal. In addition, the "winding assembly" in the present invention may refer to a combination of a pedestal and a winding component of an embodiment of the present invention. In addition, in the case where the winding component is an electronic component including multiple windings, fixing the conductors leading out from the multiple windings on the pedestal can make the combination of the multiple windings more stable.

[0047] It is known that existing terminals are conductive parts that connect electronic components to external conductors (circuits), and they can have different 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 winding, which includes a conductor with a circular or approximately circular cross-section, a flat conductor wire that constitutes a flat coil, etc. As long as it can constitute a winding, the present invention does not limit its shape or material.

[0048] Combine the following Figures 1 to 7 , Figures 10 to 12 A winding assembly according to an embodiment of the present invention is described.

[0049] In the present invention, the winding assembly includes at least one winding component 4 (such as Figure 3 As shown), a plurality of terminals and a pedestal. The winding component 4 can be any element including a winding. The winding component 4 includes a plurality of conductors 8, and the conductors 8 are connected to the terminals 7 (for example, the conductors 8 are clamped on the horizontal portion 73 of the terminals 7), wherein the conductors 8 refer to conductors constituting a coil, including a coil using a wire or a plate-shaped conductor. In an optional embodiment, referring to Figure 2 The horizontal portion 73 of the terminal 7 can be further connected to the conductor 8 by welding or fusing. Figure 1 As shown, the pedestal includes an opening 6, which passes through the pedestal and includes an area on the pedestal surrounded by a surrounding portion 10. When the pedestal is applied to a winding assembly, as shown in FIG. Fig.10 As shown, the conductor 8 of the winding component 4 is passed through the opening 6 and exposed in the opening 6. Optionally, the pedestal may not include the surrounding portion 10 according to actual production needs.

[0050] like Figure 1 and Fig.10 As shown, the base also includes a terminal support portion 5, which is arranged in the opening portion 6 and is used to install the terminal 7 (such as Figure 2 As shown in FIG. 1 , the terminal support portion 5 has a groove that matches a portion of the terminal 7, namely the first vertical portion 71, to accommodate and support the terminal 7. However, the terminal support portion 5 is not limited to Figure 1 The structure shown will suffice as long as it can cooperate with the terminal and support the terminal.

[0051] Optionally, a groove is formed in the terminal support portion, and its shape and size correspond to the terminal. In an embodiment of the present invention, during the process of manufacturing the winding assembly, when the terminal is installed on the terminal support portion, a portion of the terminal (for example, a portion of the first vertical portion in the embodiment of the present invention) extends outward (away from the side of the winding component) in a direction perpendicular to the plane where the pedestal is located.

[0052] Optionally, the pedestal further comprises a terminal separation portion 3 disposed between adjacent terminal support portions 5. Fig.10 As shown, the terminal separator 3 is arranged between the two terminal support parts 5 and extends from one side of the terminal support part 5. In the present invention, the terminal separator not only insulates the two adjacent terminals 7 and the conductor 8, but also limits the movement of the two adjacent terminals 7 and the conductor 8 on a plane parallel to the pedestal, especially along the direction in which the horizontal part of the terminal 7 extends. The terminal separator 3 can be made of any insulating material, preferably the terminal separator 3 is made of the same insulating material as the pedestal, and more preferably the terminal separator 3 is made of the same insulating material as the pedestal and is integrally formed with the pedestal.

[0053] In the embodiments of the present invention, the Figure 2 The terminal of the structure shown in FIG. 1 is a terminal of the structure shown in FIG. 1 , but the terminal of the present invention is not limited to such a structure, and a terminal of any structure can be adopted. Figure 2 The structure of the terminal of the winding assembly of the embodiment of the present invention is described. The terminal 7 includes at least a first vertical portion 71, a second vertical portion 72 extending from the lower part of the first vertical portion 71, and a horizontal portion 73 extending from the lower part of the second vertical portion 71. The first vertical portion 71 and the second vertical portion 72 can form an "L" shape, but the present invention is not limited to this. In addition, the terminal is plate-shaped as a whole and has a certain thickness, which can cooperate with the groove of the terminal support portion and be supported on the terminal support portion. The horizontal portion 73 can be used to connect with the conductor 8 led out from the winding component 4. Using a terminal that is roughly "L" shaped can make it easier to fix relative to the pedestal, and because it is an "L" shaped terminal, it can be configured as a structure with one end extending outward perpendicular to the plane of the pedestal, which is convenient for installation. By including the third vertical portion 74, the terminal 7 can further limit the movement of the conductor 8 in the direction in which the horizontal portion 73 extends, thereby further preventing the conductor 8 from falling off and loosening. However, the present invention is not limited thereto, and the terminal and the conductor may be electrically connected in any manner as long as the conductor 8 can be connected to the terminal 7 and the terminal 7 can be supported in the terminal support portion 5 .

[0054] In addition, if Figure 1 As shown, the pedestal further includes a conductor guide portion 13, which is configured to accommodate and guide the conductor 8 exposed in the opening portion 6, and the conductor guide portion 13 is arranged opposite to the terminal support portion 5. However, the present invention is not limited thereto, and optionally, the pedestal may not include the conductor guide portion 13, the terminal support portion may be any number of two or more, and the terminal support portion and the conductor guide portion may not be arranged opposite to each other.

[0055] like Fig.10As shown, a total of 6 terminal support portions 5 and 4 conductor guide portions 13 are provided in the opening portion 6. For example, when the winding component 4 is an inductor element including only one winding, the pedestal may only include Fig.10 The two terminal support parts 5 on the right side of the winding component 4 only need to electrically connect the two conductors 8 led out from the winding component 4 to the terminals 7, and install the two terminals 7 in the two terminal support parts 5. Fig.11 As shown, the terminal supporting portion 5 and the conductor guiding portion 13 may also be arranged adjacent to each other.

[0056] like Figure 1 As shown, the conductor guide 13 is disposed in the opening 6, and the conductor guide 13 is configured to accommodate and guide the conductor 8 passing through the opening 6. The present invention does not limit the number of the conductor guides 13, and the number can be set according to actual needs.

[0057] Optionally, the conductor guide portion 13 further includes a barrier portion 2, and the barrier portion 2 is configured to prevent the conductor 8 led out from the winding component 4 from contacting the winding component 4. Figure 4 As shown, the corresponding conductor 8 is held on the barrier 2. The barrier 2 prevents the corresponding conductor 8 from contacting the winding component 4 below the pedestal. The barrier 2 can be made of any insulating material, preferably the barrier 2 is made of the same insulating material as the pedestal, and more preferably the barrier 2 is made of the same insulating material as the pedestal and is integrally formed with the pedestal. The barrier 2 can be as follows Figure 1 The structure shown is a flat plate-like structure, but it is not limited thereto. For example, it may also be a groove with a certain curvature, as long as it can prevent the corresponding conductor 8 from contacting the winding component 4.

[0058] Optionally, the conductor guide 13 further includes a conductor stopper 1 for holding the conductor 8. The number of the conductor stoppers 1 can be any number according to actual needs. In addition, as long as the conductor 8 can be held, the conductor stopper 1 can be of any shape and structure. In an embodiment of the present invention, the conductor stopper 1 has the following features: Figure 5 The structure shown. Figure 4 and Figure 5, the conductor stopper 1 of the conductor guide 13 includes a guide surface 11 and a buckling surface 12, and the buckling surface 12 includes a first buckling surface 12a and a second buckling surface 12b. When the conductor 8 is installed in the conductor guide, the conductor 8 is placed on the baffle 2. At this time, the second buckling surface 12b of the conductor stopper 1 and the side surface opposite to the conductor stopper 1 jointly restrict the movement of the conductor 8 in the horizontal direction. The first buckling surface 12a of the conductor stopper 1 and the baffle 2 jointly restrict the movement of the conductor 8 in the vertical direction. Therefore, the conductor 8 can be reliably fixed by the conductor guide 13, thereby preventing the conductor 8 from falling off and loosening. In addition to the structure shown in this embodiment, the conductor stopper 1 can also be constructed as any other suitable structure, as long as the structure can keep the conductor 8 in the conductor guide 13. The conductor stopper 1 can be made of any insulating material, preferably the conductor stopper 1 is made of the same insulating material as the pedestal, and more preferably the conductor stopper 1 is made of the same insulating material as the pedestal and is integrally formed with the pedestal.

[0059] Optionally, the terminal support portion 5 further includes a terminal stop portion 9, and the terminal stop portion 9 is used to limit the terminal 7 in the terminal support portion 5. Figure 1 and Fig.10 As shown, a terminal stopper 9 is formed on one of the pair of side surfaces of the terminal support portion 5. The terminal stopper 9 can stop the terminal 7 installed in the terminal support portion 5, thereby further preventing the terminal 7 from being disengaged in the direction in which the second vertical portion 72 extends. Figure 1 and Fig.10 It is shown that the terminal stopper 9 is provided on only one of the two side surfaces of the terminal support portion 5, but the present invention is not limited thereto, and the terminal stopper 9 can be provided on both side surfaces at the same time. The terminal stopper 9 can be made of any insulating material, preferably the terminal stopper 9 is made of the same insulating material as the base, and more preferably the terminal stopper 9 is made of the same insulating material as the base and is integrally formed with the base.

[0060] Optionally, the pedestal is integrally formed. In the present invention, the pedestal is a roughly plate-shaped component that can be installed on one surface of the winding assembly. The pedestal can be made of insulating materials such as resin and plastic, but the present invention is not limited thereto. One or more mounting positions can be formed on the pedestal, each mounting position including a terminal support portion 5. Optionally, each mounting position also includes a conductor guide portion 13. And the terminal support portion 5 and the conductor guide portion 13 can fix multiple terminals 7 and multiple conductors 8. In the present invention, the number of mounting positions, the number of terminal support portions and conductor guide portions, and the number and arrangement of terminal support portions and conductor stop portions can be determined according to actual wiring requirements. In one embodiment, the number of mounting positions, the number of terminal support portions and conductor guide portions, and the number and arrangement of terminal support portions and conductor stop portions can be determined according to the number of conductors. In addition, the terminal support portion and the conductor guide portion are arranged relative to each other, and an opening portion 6 is provided between the terminal support portion and the conductor guide portion. In an embodiment, the pedestal can be configured to allow the conductor 8 to pass through the opening portion 6.

[0061] In addition, if Figure 1 and Fig.10 The left side of the base shows two terminal support parts 5 and two conductor stop parts 9 arranged opposite to the terminal support parts 5, wherein the two terminal support parts 5 are arranged in alignment, and the two conductor stop parts 9 are also arranged in alignment. Figure 1 and Fig.10 The middle part of the base shows two terminal support parts 5 and two conductor stop parts 9, wherein the terminal support parts 5 are arranged in an aligned manner, while the conductor stop parts 9 are arranged in a non-aligned manner. That is to say, the arrangement of the terminal support parts and the conductor stop parts in the present invention is not particularly limited, but can be appropriately adjusted according to the requirements of wiring.

[0062] According to the present invention, the conductor guide portion is used to accommodate and fix the conductor and includes a conductor stopper 1, a barrier portion 2, and a side surface of an opening portion 6 opposite to the conductor stopper. Figure 1 and Fig.10 The conductor stopper 1 of the conductor guide portion 13 can be selectively aligned or not aligned in its arrangement direction as required.

[0063] In an alternative embodiment, the number of terminal support portions 5 provided on one side of the opening may be changed according to wiring requirements. Figure 1 It is shown that two terminal support parts 5 are provided on one side of the opening, but more terminal support parts 5 can be provided on one side of the opening according to wiring requirements, or only one terminal support part 5 can be provided. In addition, the arrangement of the terminal support parts 5 can be changed according to wiring requirements. Figure 1The terminal support portions 5 are shown to be arranged in an aligned arrangement, but may also be arranged in an unaligned arrangement (as described below with reference to Figure 7 described above).

[0064] In an optional embodiment, if Figure 7 As shown, the terminal support parts 5 are not aligned in the direction in which the terminal support parts 5 are arranged. The position of each terminal support part 5 can be determined according to the wiring requirements. In the present invention, optionally, a part of the terminal support parts 5 are not aligned in the direction in which they are arranged and a part of the terminal support parts 5 are aligned in the direction in which they are arranged, or the terminal support parts 5 are all not aligned in the direction in which they are arranged, or the terminal support parts 5 are all aligned in the direction in which they are arranged.

[0065] Similarly, in an optional embodiment, the number and arrangement of the conductor guides 13 and the conductor stoppers 1 can also be changed according to wiring requirements. Figure 1 It is shown that four conductor guides 13 and four conductor stoppers 1 are arranged opposite to the terminal support portion, but more conductor guides 13 and conductor stoppers 1 may be arranged according to wiring requirements, or only one conductor guide 13 and conductor stopper 1 may be arranged. Figure 1 The conductor guide portion 13 and the conductor stop portion 1 are shown to be arranged in an aligned arrangement (eg, Figure 1 ), but can also be arranged to be misaligned (e.g., Figure 1 The middle part of the pedestal is shown).

[0066] In an optional embodiment, if Figure 7 As shown, the conductor stopper 1 of the conductor guide portion is not aligned in the direction in which the conductor stopper 1 is arranged. The position of each conductor stopper 1 of each conductor guide portion can be determined according to the wiring requirements. In the present invention, optionally, a part of the conductor stopper 1 of the conductor guide portion is not aligned in the direction in which it is arranged and a part of the conductor stopper 1 is aligned in the direction in which it is arranged, or the conductor stopper 1 of the conductor guide portion is not aligned in the direction in which it is arranged, or the conductor stopper 1 of the conductor guide portion is aligned in the direction in which it is arranged. In addition, the barrier portion 2 of the conductor guide portion can be continuous (for example, Figure 1 The left part of the pedestal is shown), or it can be discontinuous (for example, Figure 1 Therefore, the present invention has no limitation on the arrangement of the barrier portion 2, as long as it can carry the conductor and set the conductor stop portion.

[0067] In another optional embodiment, if Figure 6 and Fig.12As shown, a plurality of conductor accommodating spaces with height differences are formed on the barrier portion 2. Optionally, a conductor partition wall 14 is formed between adjacent conductor accommodating spaces in the plurality of conductor accommodating spaces. Figure 6 and Fig.12 As shown, the conductor guide 13 is divided into two upper and lower conductor accommodating spaces by a conductor partition wall rising from the barrier 2. The upper conductor accommodating space is composed of one side (one side of the conductor guide) where the opening 6 is connected to the conductor guide 13, the barrier 2 and the conductor partition wall 14, and plays a role in accommodating and limiting the conductors accommodated therein, and the lower conductor accommodating space is composed of the barrier 2, the conductor partition wall 14 and the other side of the conductor guide, and plays a role in accommodating and limiting the conductors accommodated therein. The upper and lower conductor accommodating spaces are configured so that the barrier 2 of the two conductor accommodating spaces has a height difference. The size of the height difference is such that the two conductors placed in the left and right conductor accommodating spaces with a height difference do not contact each other. That is, the height difference is determined according to the diameter of the conductor 8. Although in the embodiment of the present invention, the conductor partition wall 14 is used to separate the conductor guide 13 into a plurality of conductor accommodating spaces, the present invention is not limited thereto, and other structures can also be used to replace the conductor partition wall to achieve separation, for example, the conductor stopper can be used to achieve separation. In addition, the conductor partition wall 14 may not be provided, for example, the baffle 2 may be formed into a groove shape with a certain curvature to hold the conductor placed in the conductor accommodating space. The conductor partition wall 14 may be formed of any insulating material, preferably the conductor partition wall 14 is formed of the same insulating material as the pedestal, and more preferably the conductor partition wall 14 is formed of the same insulating material as the pedestal and is integrally formed with the pedestal.

[0068] like Figure 6 and Fig.11 As shown, the pedestal includes 6 terminal support parts 5 and 1 conductor guide part 13, wherein at least one terminal support part 5 can be arranged adjacent to the conductor guide part 13, while the other terminal support parts 5 are neither adjacent to nor strictly opposite to the conductor guide part 13. As mentioned above, the present invention is not limited thereto, and according to actual needs, the terminal support parts can be any number of two or more, the conductor guide parts can be any number, and the positional relationship between the terminal support parts and the conductor guide parts can be selected according to the wiring requirements, and is not limited to the situation shown in the embodiments of the present invention.

[0069] Optionally, the conductor 8 includes at least one main conductor and at least one secondary conductor. When the winding component is an inductor, it may have only one single-layer coil, that is, two conductors, one of which may be the main conductor and the other the secondary conductor. When the winding component is a transformer component, it may have at least one primary coil and one secondary coil, the conductor of the primary coil may be the main conductor and the conductor of the secondary coil may be the secondary conductor. Of course, the present invention is not limited to this, and other settings may be made according to actual needs.

[0070] Combine the following Figures 8 to 9 , Fig.13 A method for manufacturing a winding assembly according to an embodiment of the present invention is described.

[0071] Reference Figure 8 In an embodiment of the present invention, the method for manufacturing a winding assembly may include: step S801, connecting the conductor 8 led out from the winding component 4 to the terminal 7, for example, clamping the conductor 8 on the horizontal portion 73 of the terminal 7. Specifically, for example, when connecting the conductor 8 led out from the winding component 4 to the terminal 7, the end of the conductor 8 of the winding component 4 is fixed relative to the terminal 7; step S803, passing the terminal 7 through the opening portion 6 to mount the winding component 4 on the pedestal, wherein the pedestal has a through opening portion 6, and the winding component 4 can be fixed by various means such as snapping when mounted on the pedestal, and the positional relationship between the winding component 4 and the pedestal is not particularly limited, and the size and shape of the opening portion 6 of the pedestal can be set so that the terminal 7 can easily pass through; step S805, fixing the terminal 7 connected with the conductor 8 in the opening portion 6, specifically, installing the first vertical portion 71 of the terminal 7 to the terminal support portion 5 of the opening portion 9, wherein the groove of the terminal support portion 5 is set to be slightly larger than the accommodated portion of the terminal 7, and a pair of opposite side surfaces of the terminal support portion 5 can limit the movement of the terminal 7.

[0072] In an alternative embodiment, reference Fig. 9 (Steps S901, S903, S905), the manufacturing method of the winding assembly may further include: in the process of fixing the terminal 7 connected to the conductor 8 in the opening portion 6, further fixing the conductor 8 with the conductor stopper 1, and the specific fixing method refers to the previous description of the conductor stopper 1, which will not be repeated here.

[0073] In an optional embodiment, the method for manufacturing the winding assembly may further include: finally, welding or soldering the connection between the conductor 8 and the terminal 7 to complete the manufacture of the winding assembly. Since the opening of the base of the present invention is larger than that of the prior art (capable of passing the terminal), the terminal and the conductor can be welded or soldered in a centralized manner in the final process, thereby improving production efficiency.

[0074] The above method achieves reliable connection between the conductor and the terminal by fixing the conductor and the terminal on the pedestal through simple operation on the conductor and the terminal. The manufacturing method has simple process and high production efficiency in production. In addition, since this manufacturing method only adds one layer of pedestal thickness to the volume of the winding component and hardly increases the occupied area of ​​the component, it is also conducive to the miniaturization of the winding assembly.

[0075] In an optional embodiment, as described above, a terminal stopper 9 may be formed on at least one of a pair of opposite side surfaces of the terminal support portion 5. In this case, the method for manufacturing the winding assembly may further include: when fixing the terminal 7 connected with the conductor 8 in the opening portion 6, specifically, when installing the first vertical portion 72 of the terminal 7 to the terminal support portion 5, the first vertical portion 71 of the terminal 7 is located on a side of the terminal stopper 9 away from the opening portion, that is, stopped by the terminal stopper 9. With reference to the above description of the pedestal, the terminal stopper 9 can stop the terminal 7 installed in the terminal support portion 5, thereby preventing the terminal 7 from being disengaged along the direction in which the second vertical portion 72 extends.

[0076] In an optional embodiment, as described above, a plurality of conductor accommodating spaces with height differences may be formed on the barrier portion 2 of at least one conductor guide portion 13. In this case, referring to Fig.11 and Fig.13 In one embodiment, the manufacturing method of the winding assembly may include: step S1301, connecting the conductor 8 led out from the winding component 4 to the terminal 7, specifically, electrically connecting the conductor 8 to the horizontal portion 73 of the terminal 7; step S1303, passing the terminal 7 through the opening portion 6 to mount the winding component 4 on a pedestal, wherein the pedestal has a through opening portion 6, and the size and shape of the opening portion 6 of the pedestal are set to enable the terminal 7 to pass through easily; step S1305, fixing the terminal 7 connected with the conductor 8 in the opening portion 6, and holding the conductor 8 in a plurality of conductor accommodating spaces of the conductor guide portion 13, specifically, the conductor 8 can be held in the conductor guide portion 13 by means of a conductor stopper or a conductor partition wall, and the specific situation can refer to the above description, and optionally, the conductors held in different conductor accommodating spaces of the same conductor guide portion 13 can be selectively crossed, such as Fig.11 As shown, the space can be more fully utilized by crossing, which is conducive to the miniaturization of the pedestal and the winding assembly. Due to the height difference of the conductor accommodating space, it can be further ensured that the conductors accommodated in the adjacent conductor accommodating spaces do not contact each other and are insulated. In addition, the order of the operation of installing the terminal 7 on the terminal support portion 5 and the operation of installing the conductor 8 on the conductor guide portion 13 is not particularly limited.

[0077] The above manufacturing method has simple process and high production efficiency in production, and is conducive to the miniaturization of winding components. In addition, when the winding component is a transformer, and its conductor includes a main conductor of the primary coil and a secondary conductor of the secondary coil, it is preferred that the main conductor and the secondary conductor are insulated from each other without contact, and it is further preferred that there is a certain distance between the terminal support portion corresponding to the main conductor and the terminal support portion corresponding to the secondary conductor, and it is further preferred that all the terminals corresponding to the main conductors are installed on the terminal support portion on the same side, in order to achieve the effect of primary and secondary circuit isolation, that is, high and low voltage isolation. By Fig.11 By keeping the conductor in a conductor accommodating space with a height difference as shown, the effect of insulating the main conductor and the secondary conductor from each other without contact can be achieved. By reasonably configuring the positions of the terminal support parts, a certain distance can be made between the terminal support parts corresponding to the main conductor and the terminal support parts corresponding to the secondary conductor. Furthermore, all the terminals corresponding to the main conductors can be installed on the terminal support parts on the same side, thereby achieving the effect of high and low voltage isolation.
