Description
Technical Field

[0002] An inductor is one of the three fundamental passive components in electronic circuits, capable of converting electrical energy into magnetic energy and storing it. The structure of an inductor is similar to a transformer, but it has only one winding. An inductor has a certain inductance, impeding only changes in current. If no current is flowing through the inductor, it will attempt to impede the current flow when the circuit is closed; if current is flowing through the inductor, it will attempt to maintain a constant current when the circuit is open. Inductors are also known as chokes, reactors, or dynamic reactors.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: This invention avoids short circuit defects caused by insufficient insulation between powder particles leading to short circuits between terminals, and improves the insulation performance of inductor products. This structural method can achieve high reliability and heat resistance for short circuit protection in cold-pressed integrated inductors, hot-pressed integrated inductors, and copper-iron co-fired inductors. The resulting integrated inductor provides a safe and failure-proof prerequisite for circuit boards to connect to higher voltages and higher temperatures. While improving the voltage withstand capability of inductor products, it can also reduce losses and improve high insulation reliability. The present invention allows for adjustment of the distance between the middle block, side block, and vertical block via the first and second insert rods, thereby adjusting the wrapping range of the entire wrapping assembly. It is suitable for limiting the wrapping of different inductive short-circuit protection assemblies and can wrap and protect the soft magnetic body surface of the inductive short-circuit protection assembly.

When multiple sets of inductive short-circuit protection components are assembled, the rotating column is inserted into the insertion hole of another set of middle blocks. At the same time, when the threaded head is rotated and inserted, it can spiral into the screw hole, thereby completing the locking of adjacent wrapping components.

[0019] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown in the figure, this disclosure proposes an inductor short-circuit protection structure, including: an inductor short-circuit protection component 1, which includes a first short-circuit protection device 11, a second short-circuit protection device 12, and a third short-circuit protection device 13. Each of the first, second, and third short-circuit protection devices 11, 12, and 13 is composed of an insulating composite material 14, terminals 15, and copper sheets 16. A wrapping component 2 is provided on the outer surface of the inductor short-circuit protection component 1. Locking components 3 are provided at the top and bottom of the wrapping component 2. Adjacent inductor short-circuit protection components 1 are locked together through the wrapping component 2 and the locking components 3. The wrapping component 2 corresponds to the inductor short-circuit protection component 1. A pressing component 4 is provided at the position of terminal 15, and a moving component 5 is provided outside the pressing component 4 for the wrapping component 2. The pressing component 4 and the moving component 5 are movably connected. The wrapping component 2 includes a middle block 21, and there are four sets of the middle blocks 21. The four sets of the middle blocks 21 are located at the top and bottom of the middle of both sides of the inductor short-circuit protection component 1. Side blocks 22 are provided at both ends of the middle blocks 21. Vertical blocks 26 are fixed at the bottom of the four right-angled sides of the side blocks 22. The middle blocks 21, side blocks 22 and vertical blocks 26 wrap around the outside of the inductor short-circuit protection component 1. The locking component 3 includes a fixing post 34, and there are two sets of the fixing post 34. The inductor short-circuit protection component 1 has two intermediate blocks 21 on one side with fixed posts 34 rotatably mounted on their surfaces. A screw cylinder 37 is provided at one end of the fixed post 34 facing the other side of the inductor short-circuit protection component 1. A threaded head 310 is fixed at the end of the screw cylinder 37 away from the fixed post 34, and the threaded head 310 is threadedly inserted into the surface of the intermediate block 21. The moving component 5 includes a moving frame 54, with a slider 55 slidably connected inside the moving frame 54. A rotating post 56 is rotatably mounted inside the slider 55. The pressing component 4 includes vertical plates 41, with four sets of vertical plates 41. The four sets of vertical plates 41 are respectively connected to the top of the inductor short-circuit protection component 1 near both ends of the moving frame 54. The bottom vertical surface is pressed into contact, and a horizontal plate 45 is slidably inserted into the surface of the vertical plate 41. The horizontal plate 45 is in sliding contact with the top and bottom horizontal surfaces of both ends of the inductor short-circuit protection component 1. When using the device, the inductor short-circuit protection component 1 is installed inside the wrapping component 2. After adjusting the wrapping range of the wrapping component 2, it covers the outer surface of the soft magnetic body of the inductor short-circuit protection component 1. According to the position of the terminal 15 and the copper sheet 16 of the inductor short-circuit protection component 1, the bent terminal 15 is protected and covered by the moving component 5 and the pressing component 4. When in use, the pressing component 4 is removed, and multiple sets of inductor short-circuit protection components 1 are spliced together by the locking component 3 for easy handling and splicing installation.
[0021] like Figure 1 , Figure 2 and Figure 12 As shown, in some embodiments, the first short-circuit protection device 11, the second short-circuit protection device 12, and the third short-circuit protection device 13 are all soft magnetic bodies. The insulating composite material 14 of the first short-circuit protection device 11 and the third short-circuit protection device 13 is fixed in the middle of the soft magnetic body. The terminals 15 of the first short-circuit protection device 11 are bent from both ends to the top of the soft magnetic body. The terminals 15 of the second short-circuit protection device 12 and the third short-circuit protection device 13 extend from the same side and are bent on the side of the soft magnetic body. The first short-circuit protection device 11 and the third short-circuit protection device 13 have two terminals 15, and the second short-circuit protection device 12 has four terminals 15. The insulating composite material 14 of the second short-circuit protection device 12 has two forms: in one form, the insulating composite material 14 is fixed to the terminals 15 of the second short-circuit protection device 12. On the surface of the 5-exit end, another type of insulating composite material 14 is fixed inside the soft magnetic body between the two terminals 15. The copper sheet 16 of the first short-circuit protection device 11 is fixed in the middle position of the insulating composite material 14, and both ends of the copper sheet 16 of the first short-circuit protection device 11 are fixedly connected to the terminals 15. The copper sheet 16 of the third short-circuit protection device 13 is connected to the terminals 15 and fixed inside the soft magnetic body. The copper sheet 16 of the second short-circuit protection device 12 is two sets of U-shaped fixed inside the soft magnetic body, and both ends of the copper sheet 16 are fixedly connected to the corresponding terminals 15 on the outside of the second short-circuit protection device 12. Among them, a round enameled copper coil 17 is fixed inside the soft magnetic body of the third short-circuit protection device 13, and the copper sheet 16 of the two terminals 15 of the third short-circuit protection device 13 is electrically connected to the round enameled copper coil 17.
[0022] It is understandable that the copper sheet 16 conductor of the first short-circuit protection device 11 is plated with copper-nickel-tin on the surface of the terminal 15 near the top side of the soft magnetic body; an insulating composite material 14 is added between the bent wire end of the copper sheet 16 conductor and the first terminal 15 after metal plating, or on the bottom surface, to prevent short circuit between terminals 15. In the third short-circuit protection device 13, the round enameled copper coil 17 and the bent wire end of the copper sheet 16 are exposed outside the body, and the surface is plated with conductive metal to form an SMD soldered conductive terminal 15. The bent wire end of the conductor and the first terminal 15 after metal plating are added with an insulating composite material 14 to prevent short circuit between terminals 15. The structure and method of this short-circuit protection inductor can avoid short circuit failure caused by insufficient insulation between powder particles and short circuit between terminals 15, and improve the insulation performance of the inductor product. This structural method can achieve high reliability and heat resistance for short circuit protection in cold-pressed integrated inductors, hot-pressed integrated inductors, and copper-iron co-fired inductors. The resulting integrated inductor provides a safe and failure-proof prerequisite for circuit boards to be used with higher voltage and higher temperature connections. While improving the voltage resistance of inductor products, it can also reduce losses and improve high insulation reliability.
[0023] like Figure 3 As shown, in some embodiments, the wrapping assembly 2 further includes: a first insert 23, a first spring 24, a second insert 27, and a second spring 28. The two ends of the intermediate block 21 are fixed with the first insert 23, and the other end of the first insert 23 is slidably inserted into the side block 22. The surface of the first insert 23 is sleeved with the first spring 24, and the two ends of the first spring 24 are fixedly connected to the first insert 23 and the intermediate block 21, respectively. The bottom of the vertical block 26 at the upper end of the inductive short-circuit protection assembly 1 is fixed with the second insert 27, and the surface of the second insert 27 is sleeved with the second spring 28. The bottom of the second insert 27 is inserted into the lower vertical block 26, and the two ends of the second spring 28 are fixedly connected to the second insert 27 and the vertical block 26. The vertical block 26 is fixed with a side plate 25 at a position corresponding to the side of the inductive short-circuit protection assembly 1, and the side plate 25 is in contact with the side of the inductive short-circuit protection assembly 1.
[0024] It is understandable that the distance between the middle block 21, the side block 22 and the vertical block 26 can be adjusted by the first insertion rod 23 and the second insertion rod 27, thereby adjusting the wrapping range of the entire wrapping assembly 2. This is suitable for limiting the wrapping of different inductor short-circuit protection assemblies 1 and can wrap and protect the soft magnetic body surface of the inductor short-circuit protection assembly 1.
[0025] like Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the locking assembly 3 further includes: a stud 35, a screw ring 36, a third insert rod 38, and a third spring 39. The upper end of the inductive short-circuit protection assembly 1 has a fixed post 34 with the stud 35 facing the screw cylinder 37, and the screw cylinder 37 has a screw ring 36 rotatably mounted on the end near the stud 35. The stud 35 is threaded through the screw ring 36 and inserted into the inside of the screw cylinder 37. The lower end of the inductive short-circuit protection assembly 1 has a fixed post 34 with the third insert rod 38 facing the screw cylinder 37, and the other end of the third insert rod 38 is slidably inserted into the lower screw cylinder 37. The third insert rod 38... A third spring 39 is sleeved on the surface of the component. The two ends of the third spring 39 are fixedly connected to the fixed post 34 and the third insertion rod 38. The outer end of the intermediate block 21 connected to the fixed post 34 is rotatably mounted with a rotating post 31, and the rotating post 31 is fixedly connected to the fixed post 34. A transmission belt 33 is sleeved on the surface of the two rotating posts 31. The intermediate block 21 on the other side of the inductive short-circuit protection component 1 has an insertion hole 311 at the position where the threaded head 310 is inserted. The outer end of the rotating post 56 has a screw hole 32, and after the rotating post 56 is inserted into the insertion frame, the threaded head 310 is threaded into the screw hole 32.
[0026] It should be noted that the middle blocks 21 on both sides of the individual set of wrapping components 2 are connected and locked by fixing posts 34 and screw cylinders 37. The lower end is inserted through the third insert rod 38, and the upper end is inserted into the screw cylinder 37 through the stud 35. The threaded head 310 at the other end of the screw cylinder 37 is threaded into the middle block 21, thus locking the middle blocks 21 and side blocks 22 on both sides. According to the width of the inductive short-circuit protection component 1, the distance between the two middle blocks 21 is adjusted by rotating the screw ring 36 to engage with the stud 35, thus allowing the stud 35 to be retracted into the screw cylinder 37, thereby allowing it to wrap around the inductive short-circuit protection component 1. On both sides, when multiple sets of inductive short-circuit protection components 1 are assembled, the rotating post 31 is inserted into the insertion hole 311 of another set of intermediate blocks 21. At the same time, when the threaded head 310 is rotated and inserted, it can spiral into the screw hole 32, thereby locking the adjacent packaged components 2. Then, multiple sets of inductive short-circuit protection components 1 can be spliced and installed. It can be used for splicing and receiving inductive short-circuit protection components 1 after production, or for splicing and installation. The belt of the transmission belt 33 connecting the two rotating posts 31 can be replaced with a belt of different sizes according to the height of the inductive short-circuit protection components 1 to maintain the transmission connection of the pulleys of the two connecting rotating posts 31.
[0027] like Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, in some embodiments, the moving component 5 further includes: a plug plate 51, an adjusting screw 52, and a connecting rod 53. The plug plate 51 is slidably inserted into the side plate 25 facing the moving frame 54. The adjusting screw 52 is threadedly inserted into the outer surface of the side plate 25 at the upper end of the inductive short-circuit protection component 1. The plug plate 51 is rotatably connected to the front end of the adjusting screw 52. The top and bottom of both ends of the moving frame 54 are rotatably connected to the connecting rod 53, and the other end of the connecting rod 53 is rotatably connected to the plug plate 51 through a rotating shaft. The top of the slider 55 is threadedly inserted with a locking bolt 59, and the bottom of the locking bolt 59 is in pressing contact with the moving frame 54. The pressing component 4 further includes: a first protruding plate 42, a connecting plate 43, and a second protruding plate 44. The vertical plate 41 is provided with a connecting plate 43 on the side away from the inductive short-circuit protection component 1, and the connecting plate 43 is fixedly connected to the horizontal plate 45. The inductive short-circuit protection component 1 is... A first protruding plate 42 is slidably inserted into the vertical plate 41 at the end, and a second protruding plate 44 is slidably inserted into the connecting plate 43 at the upper end of the inductive short-circuit protection component 1; wherein, slots are provided on the vertical plate 41 and connecting plate 43 at the lower end of the inductive short-circuit protection component 1 corresponding to the positions of the first protruding plate 42 and the second protruding plate 44, and a triangular plate 46 is fixed at the end of the vertical plate 41 near the horizontal plate 45; wherein, the triangular plate 46 cooperates with the horizontal plate 45 to bend the terminal 15 of the second short-circuit protection device 12, a connecting seat 58 is fixed at the inner end of the rotating column 56, and a bidirectional screw 57 is rotatably installed at the center of the connecting seat 58, and screw blocks 48 are threaded on both ends of the bidirectional screw 57, and a rotating seat 47 is rotatably connected between the screw blocks 48 and the connecting plate 43; wherein, the two ends of the rotating seat 47 are rotatably connected to the screw blocks 48 and the connecting plate 43 through two rotating shafts in different directions.
[0028] It should be noted that the cooperation between the pressing component 4 and the moving component 5 is for use with three different models of inductor short-circuit protection components 1. For example, when installed on the first short-circuit protection device 11, after the wrapping component 2 wraps around the first short-circuit protection device 11, since the terminals 15 of the pressing component 4 are located at both ends, the pressing components 4 at both ends need to be used. First, the two sets of vertical plates 41 are brought closer together by the bidirectional screw 57, and the two sets of vertical plates 41 are aligned with the same vertical line by the rotating column 56. The first protruding plate 42 and the second protruding plate 44 are pulled out to connect the two vertical plates 41 and the connecting plate 43. By rotating the adjusting screw 52, the insert plate 51 is retracted into the side plate 25, and at the same time, the moving component is driven. As frame 54 moves, because vertical plate 41 is connected to screw block 48 via rotating seat 47, vertical plate 41 also moves towards both ends of the first short-circuit protection device 11, which can vertically bend the protruding copper sheet 16 and terminal 15. Then, by manually pushing horizontal plate 45, the terminal 15 and copper sheet 16 are horizontally bent to form the shape of the first short-circuit protection device 11. It can automatically bend the terminal 15 and copper sheet 16, and vertical plate 41 and horizontal plate 45 protect the outer surface of the bent copper sheet 16 and terminal 15. When it is necessary to connect terminal 15, slide block 55 moves along moving frame 54 to misalign the vertical plate 41 and horizontal plate 45 with the terminal 15. The actual state is as follows. Figure 7 and Figure 8 As shown; when used in conjunction with the second short-circuit protection device 12, because the terminals 15 of the second short-circuit protection device 12 protrude from one side and there are four of them, and the adjacent terminals 15 bend in opposite directions, it can be simply understood that the two middle terminals 15 bend towards the middle and the two outer terminals bend outward. After the moving frame 54 moves outward on the insert plate 51, the pressing assembly 4 moves away from the second short-circuit protection device 12, and the vertical plate 41 and the horizontal plate 45 are rotated to a horizontal state with the rotating column 56. The position of the two vertical plates 41 is adjusted by rotating the bidirectional screw 57, and the vertical plate 41 and the horizontal plate 45 are rotated to the position as shown by the rotating seat 47. Figure 10 As shown, the triangular plate 46 is positioned between the two terminals 15. Then, as the triangular plate 46 moves towards the second short-circuit protection device 12 along with the moving frame 54, the terminals 15 and copper sheet 16 contact and press against the inclined surfaces on both sides of the triangular plate 46, bending them to both sides until they contact the horizontal plate 45. The middle of the horizontal plate 45 is aligned with the central axis of the triangular plate 46. The horizontal plate 45 then presses and bends the terminals 15, providing protection. When using the third short-circuit protection device 13, since the third short-circuit protection device 13 has two terminals 15 that extend from the same side and bend vertically, it is necessary to rotate the rotating shaft of the rotating seat 47 and the screw block 48 to reverse the directions of the two sets of vertical plates 41 and horizontal plates 45. Figure 11As shown, the terminal 15 and copper sheet 16 are bent at right angles by the vertical plate 41 and the horizontal plate 45. The two horizontal plates 45 contact the top and bottom of the third short-circuit protection device 13 respectively, bending and covering the terminal 15. The distance between the two vertical plates 41 is adjusted by the bidirectional screw 57 according to the position of the terminal 15, so that it corresponds to the position where the terminal 15 protrudes. The moving component 5 and the pressing component 4 in this solution can be used for three different models of inductor short-circuit protection components 1. They need to be adjusted before use. For example, the first short-circuit protection device 11 needs to protect the terminals 15 at both ends, while the second short-circuit protection device 12 and the third short-circuit protection device 13 protect the terminal 15 protruding from one side. The dimensions of the vertical plate 41 and the horizontal plate 45 in this solution are not fixed. Different dimensions can be used to adapt to more inductor short-circuit protection components 1.
[0029] Working principle: When using the device, the inductive short-circuit protection component 1 is installed inside the wrapping component 2. The distance between the middle block 21, side block 22, and vertical block 26 can be adjusted by the first insertion rod 23 and the second insertion rod 27, thereby adjusting the wrapping range of the entire wrapping component 2. It is suitable for limiting the wrapping of different inductive short-circuit protection components 1 and can wrap and protect the soft magnetic body surface of the inductive short-circuit protection component 1. The middle blocks 21 on both sides of a single wrapping component 2 are connected and locked by the fixing post 34 and the screw cylinder 37. The lower end is inserted through the third insertion rod 38, and the upper end is inserted into the screw cylinder 37 through the screw post 35. The threaded head 310 at the other end of the screw cylinder 37 is threaded into the middle block 21, thus completing the locking of the middle blocks 21 and side blocks 22 on both sides. Based on the width of the inductor short-circuit protection component 1, the screw ring 36 is rotated to engage with the stud 35, causing the stud 35 to retract into the screw cylinder 37. This adjusts the distance between the two intermediate blocks 21, allowing them to wrap around both sides of the inductor short-circuit protection component 1. When assembling multiple sets of inductor short-circuit protection components 1, the rotating post 31 is inserted into the insertion hole 311 of another set of intermediate blocks 21. Simultaneously, when the threaded head 310 is rotated and inserted, it spirals into the screw hole 32, thus locking adjacent wrapping components 2. This allows multiple sets of inductor short-circuit protection components 1 to be spliced and installed. This method can be used for splicing and receiving inductor short-circuit protection components 1 after production, or for splicing and installation. The belt of the drive belt 33 connecting the two rotating posts 31 is adjusted according to the inductor short-circuit protection component. The height of component 1 is changed to different sizes of belts to maintain the transmission connection between the pulleys of the two connecting columns 31. The cooperation between the pressing component 4 and the moving component 5 is for the use of three different models of inductor short-circuit protection components 1. For example, when installed on the first short-circuit protection device 11, after the wrapping component 2 wraps around the first short-circuit protection device 11, since the terminals 15 of the pressing component 4 are located at both ends, the pressing components 4 at both ends need to be used. First, the two sets of vertical plates 41 are brought closer by the bidirectional screw 57, and the two sets of vertical plates 41 are made to be on the same vertical line by the rotating column 56. The first protruding plate 42 and the second protruding plate 44 are pulled out to connect the two vertical plates 41 and the connecting plate 43. By rotating the adjusting screw 52, the insert plate 51 is retracted. Inside the side plate 25, the moving frame 54 is also moved. Because the vertical plate 41 is connected to the screw block 48 through the rotating seat 47, the vertical plate 41 will also move towards both ends of the first short-circuit protection device 11, which can vertically bend the protruding copper sheet 16 and terminal 15. Then, by manually pushing the horizontal plate 45, the terminal 15 and copper sheet 16 are bent laterally to form the shape of the first short-circuit protection device 11. It can automatically bend the terminal 15 and copper sheet 16, and the vertical plate 41 and horizontal plate 45 protect the outer surface of the bent copper sheet 16 and terminal 15. When it is necessary to connect the terminal 15, the slider 55 is moved along the moving frame 54 to misalign the vertical plate 41 and horizontal plate 45 with the terminal 15. The actual state is as follows. Figure 7 and Figure 8As shown; when used in conjunction with the second short-circuit protection device 12, because the terminals 15 of the second short-circuit protection device 12 protrude from one side and there are four of them, and the adjacent terminals 15 bend in opposite directions, it can be simply understood that the two middle terminals 15 bend towards the middle and the two outer terminals bend outward. After the moving frame 54 moves outward on the insert plate 51, the pressing assembly 4 moves away from the second short-circuit protection device 12, and the vertical plate 41 and the horizontal plate 45 are rotated to a horizontal state with the rotating column 56. The position of the two vertical plates 41 is adjusted by rotating the bidirectional screw 57, and the vertical plate 41 and the horizontal plate 45 are rotated to the position as shown by the rotating seat 47. Figure 10 As shown, the triangular plate 46 is positioned between the two terminals 15. Then, as the triangular plate 46 moves towards the second short-circuit protection device 12 along with the moving frame 54, the terminals 15 and copper sheet 16 contact and press against the inclined surfaces on both sides of the triangular plate 46, bending them to both sides until they contact the horizontal plate 45. The middle of the horizontal plate 45 is aligned with the central axis of the triangular plate 46. The horizontal plate 45 then presses and bends the terminals 15, providing protection. When using the third short-circuit protection device 13, since the third short-circuit protection device 13 has two terminals 15 that extend from the same side and bend vertically, it is necessary to rotate the rotating shaft of the rotating seat 47 and the screw block 48 to reverse the directions of the two sets of vertical plates 41 and horizontal plates 45. Figure 11 As shown, the terminal 15 and copper sheet 16 are bent at right angles by the vertical plate 41 and the horizontal plate 45. The two horizontal plates 45 contact the top and bottom of the third short-circuit protection device 13 respectively, bending and covering the terminal 15. The distance between the two vertical plates 41 is adjusted by the bidirectional screw 57 according to the position of the terminal 15, so that it corresponds to the position where the terminal 15 protrudes. The moving component 5 and the pressing component 4 in this solution can be used for three different models of inductor short-circuit protection components 1. They need to be adjusted before use. For example, the first short-circuit protection device 11 needs to protect the terminals 15 at both ends, while the second short-circuit protection device 12 and the third short-circuit protection device 13 protect the terminal 15 protruding from one side. The dimensions of the vertical plate 41 and the horizontal plate 45 in this solution are not fixed. Different dimensions can be used to adapt to more inductor short-circuit protection components 1.
