[0015] The beneficial effects of the present invention are as follows: The present invention is a filter inductor that can be modularly installed and is convenient for adapting to different usage requirements, effectively solving the problem of fixing the connecting cable in high-current applications. The specific beneficial effects are as follows: After the operator first determines the required inductance, the number of single-turn notched coils in the coil group is adjusted. First, rotate the rotating peeling column at the end far from the second bending fixing plate. The fitting inclined surfaces between the two groups of rotating peeling columns are offset, so that one rotating peeling column is far away from the multiple groups of rotating peeling columns at the other end until the fixed notches of the two groups of rotating peeling columns are mutually abutted. Then, by continuing to rotate, the next group of rotating peeling columns can be further peeled off. Due to different torques, the next rotating peeling column can be sequentially rotated and separated, avoiding disconnection of the single-turn notched coils in the middle of the coil group. During the process of the rotating peeling columns moving away from each other, the clamping clips at the edge are driven to disengage from the guiding tube, and at the same time, the fixed notches on the clamping clips clamping the single-turn notched coils are disengaged from the fixed protrusions on the adjacent single-turn notched coils, so that the winding length of the coil group can be shortened. The number of turns of the winding coil directly determines the actual size of the inductance. By adjustably reducing the number of winding turns and through measurement, the inductance change caused by reducing one turn to multiple turns can be obtained. During use, disassembly and adjustment are carried out to achieve precise change of multi-stage control of the inductance. In order to assist in connecting the two ends of the coil group to the circuit board when the single-turn notched coil on the coil group is detached, during detachment, the fixed notch on the single-turn notched coil at the end of the coil group is connected by an extension post to the second bent fixing plate to the circuit board, and the fixed convex notch at the other end abuts against the adjacent rotating rocker. The rotating rocker is expanded by the thrust of the thrust spring to increase the angle with the serrated plate. The other end of the rotating rocker abuts against the energizing plate to contact the energizing plate. Since the energizing plate contacts the circuit board through the first bent fixing plate, when adjusting the number of single-turn notched coils in the coil group, the connection of both ends to the circuit board is synchronously achieved.
[0016] In the future, to adapt to different inductance requirements, after detaching the first bent fixing plate and the second bent fixing plate from the clamped extrusion semi-circular plate and detaching the circular magnet from the connecting fixing rod, different coil groups with different winding numbers and circular magnets of different sizes can be replaced, which is beneficial to modular assembly and is also convenient for replacement and adjustment.
[0017] To adapt to different wiring requirements, such as rigid wires, flexible wires, and wires with terminals: when facing wires with terminals, they can be fixed by fixing nuts; when facing rigid wires or flexible wires, the rigid wires or flexible wires are passed through the through-tube until they contact the pressure plate, and then continue to pass through the pressure spring below the extrusion pressure plate until the constraint ring contacts the long rod part, causing the long rod part to move inward, so that the extrusion protrusion squeezes the wire. Then, when pulling out of the through-tube, the wire drives the extrusion protrusion to rotate inward, further squeezing the wire, and the fixation of the wire can be achieved.
[0018] The device has a simple structure. By effectively setting a modular coil group, the adjustment of different inductances can be realized, further achieving the applicability to different equipment requirements. At the same time, modular structural installation can be realized, effectively solving the problem of fixing cable connection, and having good practicality and economy, which is beneficial to the popularization and use of the device.

The serrated plate 52 is arranged on the side of the power-on plate 51 far from the circuit board 11. The power-on plate 51 and the serrated plate 52 are spaced by a spacer column 54.

A number of connecting columns 253 are provided between the restraint ring 25 and the pressure plate 251.
[0025] In implementation, when facing a wire with terminals, it can be fixed through the fixing nut 23; when facing a hard wire, when facing a hard wire and a soft wire, they are passed into the wire-passing tube 24 until they contact the pressure plate 251, and then continue to pass through the pressure spring 252 below the pressure plate 251 until the restraint ring 25 contacts the long rod portion 2432, then the long rod portion 2432 is constrained to move inward, so that the extrusion protrusion 2431 extrudes the wire, and then it moves out of the wire-passing tube 24. The wire drives the extrusion protrusion 2431 to rotate inward, further extruding the wire, and thus the fixation of the wire can be achieved.
[0026] Beneficially, a protective sleeve 17 is provided outside the coil group. The protective sleeve 17 abuts against the outer peripheral side of the single-turn notch coil 31 and supports the coil group. At the same time, it can be fixed to the circuit board 11. The attached drawing adopts a simple drawing method, and specifically refer to the actual usage method. At the same time, a connection fixing rod 151 is provided in the middle of the circular magnet 15. The connection fixing rod 151 is fixedly connected to the circuit board 11. The connection fixing rod 151 clamps the circular magnet 15 and fixes it between two coil groups, which is convenient for replacing the circular magnet 15 and the coil group below.
[0027] Beneficially, a splitting member 4 is further provided on one side of the coil group. The splitting member 4 includes a guiding tube 33. A clamping clip 34 is provided on the single-turn notched coil 31. The clamping clip 34 has a C-shaped structure. The middle part of the clamping clip 34 clamps the single-turn notched coil 31. The guiding tube 33 penetrates through and is slidably connected to the clamping clips 34 on a plurality of single-turn notched coils 31. A rotating peeling column 35 is provided in the middle of the clamping clip 34. The rotating peeling column 35 is rotatably connected to the clamping clip 34. The splitting member 4 further includes a rotating shaft 32. The rotating shaft 32 penetrates through and is slidably connected to the rotating peeling column 35. The rotating shaft 32 penetrates through and is slidably connected to the rotating peeling column 35. Fitting inclined surfaces 351 are provided at both ends of the rotating peeling column 35. Fixed notches 352 are provided on the fitting inclined surfaces 351. The fitting inclined surfaces 351 between adjacent rotating peeling columns 35 are mutually abutted and fitted.
[0028] Meanwhile, abrasive paste; or a friction surface; or wax liquid is provided between the rotating peeling column 35 and the rotating shaft 32 to increase the frictional force for fixation. The rotational torque increases sequentially to prevent the rotating peeling column 35 in the middle from rotating during the rotation of one end.
[0029] In implementation, first rotate the rotating peeling column 35 at the end far from the second bending fixing plate 531. The fitting inclined surfaces 351 between the two groups of rotating peeling columns 35 are displaced, causing the rotating peeling column 35 at one end to move away from the multiple groups of rotating peeling columns 35 at the other end until the fixed notches 352 of the two groups of rotating peeling columns 35 are mutually abutted. Then, by continuing to rotate, the next group of rotating peeling columns 35 can be further peeled off. Due to the different torques, the next rotating peeling column 35 can be sequentially rotated and separated, preventing the single-turn notched coils 31 in the middle of the coil group from being disconnected. During the process of the rotating peeling columns 35 moving away from each other, the clamping clips 34 at the edge are driven to disengage from the guiding tube 33, and at the same time, the fixed notches 311 on the clamping clips 34 clamping the single-turn notched coils 31 are disengaged from the fixed protrusions 312 on the adjacent single-turn notched coils 31, thus shortening the winding length of the coil group.
[0030] The working principle of the present invention: After the staff first determines the required inductance, they adjust the number of single-turn notched coils 31 in the coil group. First, they rotate the rotating stripping column 35 away from one end of the second bent fixed plate 531, and the fitting inclined surface 351 between the two groups of rotating stripping columns 35 is offset, so that the rotating stripping columns 35 at one end are away from the multiple groups of rotating stripping columns 35 at the other end, until the fixed notches 352 of the two groups of rotating stripping columns 35 abut against each other, and then the next group of rotating stripping columns 35 can be further stripped by continuing to rotate. Due to the difference in torque, the next rotating stripping column 35 can be rotated and separated in sequence, avoiding the occurrence of a problem in the coil group. The single-turn gap coil 31 at the bottom is disconnected, and in the process of rotating the stripping rods 35 away from each other, the clamping clip 34 at the edge is driven to separate from the guide tube 33, and at the same time, the clamping clip 34 clamps the fixed notch 311 on the single-turn gap coil 31 to separate from the fixed protrusion 312 on the adjacent single-turn gap coil 31, so that the winding length of the coil group can be shortened. The number of winding coils directly determines the actual size of the inductance. By reducing the number of winding turns, the inductance change caused by reducing one turn to multiple turns can be obtained through measurement. When in use, it can be disassembled and adjusted to achieve accurate changes in multi-stage control of inductance. In order to assist the single-turn notch coil 31 on the coil group to be detached, the two ends of the coil group are connected to the circuit board 11. When detached, the fixed recess 311 on the single-turn notch coil 31 at the end of the coil group is connected to the second bent fixed plate 531 to the circuit board 11 by the extension column 532, and the fixed protrusion 312 at the other end abuts against the adjacent rotating seesaw 522, so that the rotating seesaw 522 is expanded by the thrust of the thrust spring 523 to expand the angle with the serrated plate 52, and the other end of the rotating seesaw 522 abuts against the power-on plate 51 to contact the power-on plate 51. Since the power-on plate 51 contacts the circuit board 11 through the first bent fixed plate 53, when the number of single-turn notch coils 31 is adjusted in the coil group, the connection of the two ends to the circuit board 11 is achieved simultaneously.
[0031] In the future, in order to adapt to different inductance requirements, the first bent fixing plate 53 and the second bent fixing plate 531 can be separated from the clamped extruded semicircular plate 551, and the circular magnet 15 can be separated from the connecting fixing rod 151, so that the coil groups with different winding numbers and the circular magnets 15 of different sizes can be replaced, which is beneficial to modular assembly and easy to replace and adjust.
[0032] In order to adapt to different wiring requirements, such as hard wires, soft wires and wires with terminals: when facing wires with terminals, they can be fixed by fixing the nut 23; when facing hard wires or soft wires, the hard wires or soft wires are passed into the wire tube 24 until they contact the pressure plate 251, and then continue to pass the pressure spring 252 under the extrusion pressure plate 251 until the restraining ring 25 contacts the long rod 2432, and the long rod 2432 is restrained to move inward, so that the extrusion protrusion 2431 squeezes the wire, and then it is separated from the wire tube 24 outward, and the wire drives the extrusion protrusion 2431 to rotate inward, further squeezing the wire, and the wire can be fixed.
