Description

Technical Field

[0001] The present invention relates to the technical field of inductors, and in particular to a combined inductor which is easy to replace. Background Art

[0002] Combined inductors are composed of multiple inductor units. These units can be of the same specifications or different specifications. They can be reasonably combined to meet different electrical performance requirements.

[0003] The working principle of the combined inductor is based on Faraday's law of electromagnetic induction. When current passes through a coil, a magnetic field is generated. The change in the magnetic field induces an electromotive force in the coil, thereby hindering the change of current. When multiple inductance units are combined together, they will affect each other. By reasonably designing the connection method of the magnetic circuit and the coil, various functions and performance optimizations can be achieved, such as increasing inductance, reducing losses, and enhancing anti-interference capabilities.

[0004] The existing Chinese patent with publication number CN112233878B discloses a combined inductor that is easy to replace, but the above patent also has the following defects: First, the above patent fixes the frame on the inductor by inserting it into the slot. However, when the coil is actually wound on the frame, the coil will gradually become thicker due to the increase in the number of windings. Ultimately, the overly thick coil will affect the insertion of the frame into the slot. Second, the spacing between adjacent slots in the above patent is a fixed value, so only a skeleton of a specified length can be installed. If the skeleton is too short or too long, it cannot be installed in the slot; Third, the combined inductor is composed of multiple groups of small inductors. The above patent is a common-mode inductor, not a combined inductor. Therefore, when assembling the combined inductor, it is necessary to control the spacing between adjacent small inductors. In the traditional combined inductor, several small inductors are fixedly set and the spacing between them cannot be adjusted. Therefore, after installation, the coils on adjacent small inductors will rub against each other.

[0005] Therefore, in order to solve the above problems, it is necessary to provide a combined inductor that is easy to replace. Summary of the invention

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] refer to Figures 1 to 16 The illustrated embodiment of the present invention is a combined inductor which is easy to replace, comprising a plurality of small inductors 1, each of which comprises a frame 2 and a coil 3 wound on the frame 2, the frame 2 being provided with two contact pins 4, and a base 51, the base 51 being provided with a plurality of groups of mounting seats 5 equally spaced in the horizontal direction, each group of mounting seats 5 comprising a top pressing seat 6 and a bottom spring pressing seat 7 distributed up and down, the bottom spring pressing seat 7 comprising a sliding frame 8, a lifting and lowering pressure plate 9 and two abutting blocks 10, the sliding frame 8 being connected to the base 51 in a sliding manner in the horizontal direction, the lifting and lowering pressure plate 9 being arranged above the sliding frame 8 (combined with the lifting and lowering pressure plate 9). Figure 4 and Figure 8 ), and the lifting and lowering pressure plate 9 is elastically connected to the sliding frame 8, two stop blocks 10 are symmetrically arranged on the lifting and lowering pressure plate 9, each stop block 10 is slidably connected to the lifting and lowering pressure plate 9 in the horizontal direction, and a translation driving member for driving the two stop blocks 10 to translate synchronously is provided between the lifting and lowering pressure plate 9 and the sliding frame 8, the top clamping seat 6 includes a fixed frame 11 and two elastic sheets 12, the fixed frame 11 is connected to the sliding frame 8, the fixed frame 11 includes a top plate 13 located directly above the lifting and lowering pressure plate 9, a plurality of limit blocks 14 are provided on the top plate 13, and the two elastic sheets 12 are symmetrically arranged on the top plate 13, and a spacing adjustment mechanism for adjusting the spacing between adjacent mounting seats 5 is also provided on the base 51.

[0021] The combined inductor of the device is composed of a plurality of small inductors 1. The two ends of the coil 3 on each small inductor 1 are respectively welded to two contact pins 4, and the skeleton 2 of the small inductor 1 is hollow. In actual use, it is necessary to install a plurality of small inductors 1 on the corresponding mounting base 5 in sequence. The specific operation process is as follows (taking the installation of a single small inductor 1 as an example). Press down the lifting and lowering plate 9. At this time, the translation drive member will synchronously drive the two blocks 10 to move toward each other. When the two blocks 10 are close to each other, The vertical frame 2 is placed on the lifting and pressing plate 9. In this process, since the frame 2 is hollow, the lower end of the frame 2 will be set outside the two abutments 10. When the lower end of the frame 2 is placed on the lifting and pressing plate 9, the two elastic sheets 12 are pressed toward each other. In the initial state, the two elastic sheets 12 expand outward toward both sides respectively. When the two elastic sheets 12 are pressed toward each other, the two elastic sheets 12 will generate elastic force to expand outward. When the two elastic sheets 12 approach each other and approach verticality, the lifting and pressing plate 9 is released. At this time, the lifting and pressing plate 9 will rise elastically. In the process of the lifting and pressing plate 9 rising, the translation drive member will synchronously drive the two stop blocks 10 to move backwards, so that the two stop blocks 10 will press against the two inner walls of the frame 2 respectively, and then the lower end of the frame 2 will be pressed from the inside to the outside through the two stop blocks 10. At the same time, with the upper part of the lifting and pressing plate 9, the two elastic sheets 12 will be inserted downward into the upper end of the frame 2. After the elastic sheet 12 is inserted into the frame 2, the elastic sheet 12 is released, so that the two elastic sheets 12 will expand outward again through elasticity, and then the two elastic sheets 12 will be pressed from the inside to the outside. The upper end of the skeleton 2 is pressed tightly, and when the lifting and pressing plate 9 rises to the top of the skeleton 2 and contacts the limit block 14, the skeleton 2 stops moving. At this time, the skeleton 2 is fixed. When it is necessary to remove the skeleton 2 from the mounting seat 5, press the lifting and pressing plate 9 downward and remove the skeleton 2 from the lifting and pressing plate 9. In summary, the mounting seat 5 of the device can be used to quickly disassemble and assemble the small inductor 1, wherein the spacing between adjacent mounting seats 5 is adjusted by the spacing adjustment mechanism of the device, so as to facilitate the installation of skeletons 2 of different sizes.

[0022] In order to show how the lifting plate 9 is elastically connected to the sliding frame 8, the following features are set: The sliding frame 8 includes a flat plate 15, and the lifting and pressing plate 9 is horizontally arranged directly above the flat plate 15. Four vertical No. 1 limit shafts 16 are fixedly arranged at the bottom of the lifting and pressing plate 9. Each No. 1 limit shaft 16 passes downward through the flat plate 15. A No. 1 spring 17 is sleeved on each No. 1 limit shaft 16. The two ends of the No. 1 spring 17 respectively contact the lifting and pressing plate 9 and the flat plate 15. The lower end of each No. 1 limit shaft 16 is screwed with a No. 1 limit nut 18 that contacts the flat plate 15 upward.

[0023] In the initial state, the No. 1 spring 17 releases its elastic force to push up the lifting and lowering pressure plate 9, so that the lifting and lowering pressure plate 9 will be in an ascending state. At this time, the No. 1 limiting nut 18 arranged at the lower end of the No. 1 limiting shaft 16 will conflict upward with the bottom of the flat plate 15, so as to prevent the No. 1 limiting shaft 16 from separating from the flat plate 15 through the No. 1 limiting nut 18. When the skeleton 2 presses downward on the lifting and lowering pressure plate 9, the lifting and lowering pressure plate 9 will descend and compress the No. 1 spring 17, so that the No. 1 spring 17 generates elastic force. Then, when the lifting and lowering pressure plate 9 is released, the No. 1 spring 17 will release its elastic force again to drive the lifting and lowering pressure plate 9 to rise.

[0024] In order to show how the two abutments 10 are slidably connected to the lifting and lowering plates 9, the following features are provided: The four end corners of the top of the lifting and pressing plate 9 are formed with vertical upward protrusions 19, and a horizontal support plate 20 is provided above the lifting and pressing plate 9. The support plate 20 is fixed on the four protrusions 19. Both ends of the lifting and pressing plate 9 are provided with horizontal limit slides 21, and the limit slides 21 are located between the corresponding two protrusions 19. Each limit slide 21 is provided with a slider 22, and one side of the slider 22 is formed with a horizontal second limit shaft 23 (such as Fig.12 As shown in the figure, two symmetrical blocks 24 are formed on the top of the lifting and pressing plate 9, and the No. 2 limit shaft 23 passes through the block 24. A No. 2 spring 25 is sleeved on the No. 2 limit shaft 23. The two ends of the No. 2 spring 25 respectively conflict with the block 24 and the slider 22, and a No. 2 limit nut 52 is screwed on one end of the No. 2 limit shaft 23 passing through the block 24. Strip avoidance grooves 26 are provided at both ends of the support plate 20, and the block 10 is arranged in the strip avoidance groove 26, and the block 10 is fixedly connected to the corresponding slider 22.

[0025] In the initial state, the No. 2 spring 25 releases its elastic force to drive the slider 22 to extend outward. During this process, the slider 22 will drive the corresponding stop block 10 to extend, and finally both the stop blocks 10 will be in the extended state. At this time, the distance between the two stop blocks 10 is the largest. Before the skeleton 2 is placed on the lifting and pressing plate 9, the lifting and pressing plate 9 is pressed downward first. During this process, the translation drive component will synchronously drive the two sliders 22 to move toward each other. When the two sliders 22 move toward each other, the two stop blocks 10 will move toward each other. At the same time, each slider 22 will compress the corresponding No. 2 spring 25, so that the No. 2 spring 25 generates elastic force. When the distance between the two stop blocks 10 is After shrinking, the vertical skeleton 2 is placed on the support plate 20 on the top of the lifting and pressure plate 9. During this process, the two blocks 10 approaching each other will be inserted upward into the lower end of the skeleton 2. Thereafter, the lifting and pressure plate 9 is released, and the lifting and pressure plate 9 will rise due to the elastic force of the No. 1 spring 17. During the rising process of the lifting and pressure plate 9, the translation drive component will synchronously drive the two blocks 10 to move backwards, so that the two blocks 10 will respectively stick to the two inner walls of the lower end of the skeleton 2. Finally, the blocks 10 will remain in a state of being tightly attached to the inner wall of the lower end of the skeleton 2 through the elastic force of the No. 2 spring 25, so that the two blocks 10 will press the lower end of the skeleton 2 from the inside to the outside.

[0026] In order to show the specific structure of the translation drive, the following features are set: The translation drive member includes two symmetrical No. 1 inclined wedge blocks 27, which are respectively fixed at the two ends of the plate 15, and each No. 1 inclined wedge block 27 is vertical. The bottom of the slider 22 is formed with a No. 2 inclined wedge block 28 that matches the No. 1 inclined wedge block 27.

[0027] When the lifting and lowering plate 9 is pressed down, the second inclined wedge block 28 provided on the lifting and lowering plate 9 will contact with the No. 1 inclined wedge block 27 downward. Thereafter, as the lifting and lowering plate 9 descends, the No. 2 inclined wedge block 28 will be driven to retract by the No. 1 inclined wedge block 27, so that the slider 22 connected to the No. 2 inclined wedge block 28 will drive the corresponding stop block 10 to retract. Finally, during the descending process of the lifting and lowering plate 9, the two stop blocks 10 will approach each other, so as to facilitate the lower end of the skeleton 2 to be sleeved on the two stop blocks 10. When the lower end of the skeleton 2 is sleeved on the two stop blocks 10, the lifting and lowering plate 9 is released. Thereafter, the lifting and lowering plate 9 rises. During the rising process of the lifting and lowering plate 9, the No. 2 inclined wedge block 28 will gradually separate from the No. 1 inclined wedge block 27, so that the No. 2 spring 25 will drive the slider 22 to extend outward through the elastic force, and finally the two stop blocks 10 will move back to back and press against the two inner walls of the lower end of the skeleton 2 respectively.

[0028] In order to facilitate pressing the two elastic sheets 12 inwardly, the following features are provided: The top plate 13 is provided with a lifting and pressing member, which includes a lifting frame and two rollers 29. The lifting frame includes a lifting plate 30 and four groups of sliding rods 31 distributed in a matrix (such as Figure 4As shown, the lifting plate 30 is horizontally arranged above the top plate 13, and four sets of slide bars 31 are fixed to the bottom of the lifting plate 30. Each set of slide bars 31 vertically passes through the top plate 13 downward, and the four sets of slide bars 31 are arranged in pairs beside the two elastic sheets 12, and each roller 29 is horizontally arranged between the corresponding two sets of slide bars 31 (as shown in FIG. Figure 6 as shown).

[0029] In the initial state, the two elastic sheets 12 expand outwards to both sides due to elastic force. Before installing the frame 2 on the mounting seat 5, the lifting frame is pressed downwards first. During this process, the lifting frame will drive the four sets of slide bars 31 to descend, so that the two rollers 29 will press the two elastic sheets 12 respectively, so that the two elastic sheets 12 expanding outwards will be pressed by the rollers 29 and gradually move inwards. Finally, the two elastic sheets 12 will be pressed to a vertical state by the two rollers 29. After that, the frame 2 is placed on the lifting and pressing plate 9. When the lower end of the frame 2 is pressed tightly by the two abutting blocks 10, , release the lifting and lowering pressure plate 9. At this time, the lifting and lowering pressure plate 9 will gradually rise. During the rising process of the lifting and lowering pressure plate 9, the two vertical elastic sheets 12 will gradually insert into the upper end of the frame 2. When the top of the frame 2 conflicts with the two rollers 29, pull the lifting frame upward, so that the two rollers 29 will gradually rise. Then, during the rising process of the rollers 29, the two elastic sheets 12 will expand outward to both sides again due to the elastic force. Finally, when the frame 2 rises to conflict with the limit block 14, the two elastic sheets 12 will press the upper end of the frame 2 from the inside to the outside.

[0030] In order to show how the sliding frame 8 is slidably connected to the base 51, the following features are provided: Both sides of the base 51 are fixed with a vertical frame plate 32 (such as Figure 7 As shown in the figure, a plurality of fixing rods 33 are arranged between the two vertical frame plates 32 and are evenly distributed in the horizontal direction. Each fixing rod 33 is horizontal, and the two ends of each fixing rod 33 are respectively fixedly connected to the two vertical frame plates 32. The sliding frame 8 also includes a plurality of sliding sleeves 34 corresponding to the fixing rods 33, each sliding sleeve 34 is fixed to the bottom of the corresponding flat plate 15, and each sliding sleeve 34 is slidably mounted on the corresponding fixing rod 33.

[0031] Each sliding frame 8 is horizontally displaced by sliding the sliding sleeve 34 on the fixed rod 33. When the distance between adjacent mounting seats 5 is adjusted by the distance adjustment mechanism, the mounting seats 5 will be horizontally displaced through the corresponding sliding frame 8, and finally the distance adjustment is achieved.

[0032] In order to show the specific structure of the spacing adjustment mechanism, the following features are set: The spacing adjustment mechanism includes a slide plate 35 and an adjustment screw 36 (such as Fig.15As shown in the figure, the slide plate 35 is horizontally arranged between the two vertical frame plates 32, and a plurality of guide slides 37 are formed at the bottom of the slide plate 35. A plurality of strip slide seats 38 corresponding to the guide slides 37 are fixedly arranged on the base 51, and each guide slide bar 37 slides horizontally in the corresponding strip slide seat 38. The adjusting screw 36 is horizontally connected to the base 51 for rotation. A threaded sleeve 39 sleeved on the adjusting screw 36 is fixedly arranged at the bottom of the slide plate 35, and a connecting plate 40 connecting a plurality of sliding sleeves 34 is fixedly arranged at the bottom of the sliding frame 8. A guide slide pin 41 is formed at the bottom of the connecting plate 40. A strip straight groove 42 is provided in the middle of the slide plate 35, and a plurality of strip oblique grooves 43 are provided at both ends of the slide plate 35. The guide slide pin 41 located in the middle penetrates downward into the corresponding strip straight groove 42, and the guide slide pins 41 located on both sides penetrate downward into the corresponding strip oblique groove 43.

[0033] When assembling the combined inductor, if the number of the small inductors 1 is odd, the small inductor 1 located in the middle will correspond to the strip straight groove 42 on the slide plate 35, and the small inductors 1 located on both sides will correspond to the strip oblique groove 43 on the slide plate 35. When adjusting the spacing of the small inductors 1, the adjusting screw 36 is rotated, and the slide plate 35 slides in the horizontal direction. During this process, the guide pin 41 located in the middle will slide in the strip straight groove 42, and the guide pin 41 located on both sides will slide in the strip oblique groove 43, so that the small inductors 1 located in the middle will slide in the strip straight groove 42. The sliding rack 8 at the top will not translate, while the sliding racks 8 at both sides will translate, thereby adjusting the spacing between adjacent small inductors 1. When assembling the combined inductor, if the number of small inductors 1 is even, then the plurality of small inductors 1 are evenly divided into two groups, and the two groups of small inductors 1 are respectively installed on the sliding racks 8 at both sides, and the middle sliding rack 8 is left empty and not installed. Therefore, when the adjusting screw 36 is rotated, the slide plate 35 will drive the plurality of small inductors 1 to translate, thereby finally achieving the spacing adjustment of the small inductors 1.

[0034] When adjusting the distance of the mounting seat 5, in order to ensure that the mounting seat 5 can be stably translated, the following features are set: The fixing frame 11 further includes a vertical plate 44 formed at the bottom of the top plate 13, the lower end of the vertical plate 44 is fixedly connected to the corresponding flat plate 15, and a vertical strip back plate 45 (such as Fig.13 As shown), each vertical plate 44 is formed with a plurality of horizontal limit strips 46, and the strip back plate 45 is provided with a plurality of strip slide grooves 47 corresponding to the limit strips 46, and each limit strip 46 slides in the corresponding strip slide groove 47.

[0035] When adjusting the spacing between adjacent small inductors 1, each sliding frame 8 will translate, thereby driving the fixed frame 11 to translate together. During this process, the vertical plate 44 on the fixed frame 11 will slide on the strip back plate 45 through the limiting strip 46 sliding in the strip slide groove 47, thereby maintaining the stability of the fixed frame 11 through the strip back plate 45.

[0036] In actual use, in order to prevent the contact pins 4 on the small inductor 1 from affecting the disassembly and assembly of the frame 2, the following features are set: A bracket 48 (such as Fig.11 As shown in FIG. 1 , two symmetrical slots 49 are provided on the bracket 48 , and the two contact pins 4 on each small inductor 1 correspond to the two slots 49 , respectively. A vertically upward conductive strip 50 is fixed in each slot 49 .

[0037] When the lower end of the skeleton 2 is pressed tightly by the two abutments 10, the lifting and pressing plate 9 will drive the skeleton 2 to rise. During this process, the two elastic sheets 12 will be inserted downward into the upper end of the skeleton 2. At the same time, the two contact pins 4 at the upper end of the skeleton 2 will be respectively inserted into the corresponding two slots 49. Finally, when the upper end of the skeleton 2 is pressed tightly by the two elastic sheets 12, the contact pins 4 on the skeleton 2 will contact the conductive strips 50 in the corresponding slots 49. Therefore, when the skeleton 2 is completely fixed, each contact pin 4 will be connected to the corresponding conductive strip 50. In actual use, the external wires can be welded to the conductive strip 50. Therefore, when the small inductor 1 is disassembled and assembled, there is no need to separate the external wires from the contact pins 4, thereby further improving the efficiency of disassembling and assembling the small inductor 1.

[0038] Working principle: The combined inductor of the device is composed of a plurality of small inductors 1. The two ends of the coil 3 on each small inductor 1 are respectively welded to two contact pins 4, and the skeleton 2 of the small inductor 1 is hollow. In actual use, it is necessary to install a plurality of small inductors 1 on the corresponding mounting base 5 in sequence. The specific operation process is as follows (taking the installation of a single small inductor 1 as an example). Press down the lifting and lowering plate 9. At this time, the translation drive member will synchronously drive the two blocks 10 to move toward each other. When the two blocks 10 are close to each other, The vertical frame 2 is placed on the lifting and pressing plate 9. In this process, since the frame 2 is hollow, the lower end of the frame 2 will be set outside the two abutments 10. When the lower end of the frame 2 is placed on the lifting and pressing plate 9, the two elastic sheets 12 are pressed toward each other. In the initial state, the two elastic sheets 12 expand outward toward both sides respectively. When the two elastic sheets 12 are pressed toward each other, the two elastic sheets 12 will generate elastic force to expand outward. When the two elastic sheets 12 approach each other and approach verticality, the lifting and pressing plate 9 is released. At this time, the lifting and pressing plate 9 will rise elastically. In the process of the lifting and pressing plate 9 rising, the translation drive member will synchronously drive the two stop blocks 10 to move backwards, so that the two stop blocks 10 will press against the two inner walls of the frame 2 respectively, and then the lower end of the frame 2 will be pressed from the inside to the outside through the two stop blocks 10. At the same time, with the upper part of the lifting and pressing plate 9, the two elastic sheets 12 will be inserted downward into the upper end of the frame 2. After the elastic sheet 12 is inserted into the frame 2, the elastic sheet 12 is released, so that the two elastic sheets 12 will expand outward again through elasticity, and then the two elastic sheets 12 will be pressed from the inside to the outside. The upper end of the skeleton 2 is pressed tightly, and when the lifting and pressing plate 9 rises to the top of the skeleton 2 and contacts the limit block 14, the skeleton 2 stops moving. At this time, the skeleton 2 is fixed. When it is necessary to remove the skeleton 2 from the mounting seat 5, press the lifting and pressing plate 9 downward and remove the skeleton 2 from the lifting and pressing plate 9. In summary, the mounting seat 5 of the device can be used to quickly disassemble and assemble the small inductor 1, wherein the spacing between adjacent mounting seats 5 is adjusted by the spacing adjustment mechanism of the device, so as to facilitate the installation of skeletons 2 of different sizes.
