Description

Technical Field

[0001] The invention relates to the technical field of inductors, and in particular to an inductor with a splicable iron core. Background Art

[0002] Inductors are mainly composed of skeletons, windings, shielding covers, packaging materials, magnetic cores or iron cores, etc. Among them, the spliced ​​iron core of the inductor is a key component to improve the performance of the inductor. It can not only enhance the inductance effect, but also optimize the working efficiency and application range of the inductor in the circuit. The spliced ​​iron core design allows the size and inductance of the inductor to be adjusted according to actual needs, which helps to improve the flexibility and adaptability of the use of the inductor.

[0003] In the case of an inductor in the form of a splicable iron core, when the two iron cores are assembled and spliced ​​for use, the two winding coils on the two iron cores need to be connected and wired. Most existing inductors lack a mechanism for wiring the two winding coils, and the wiring is usually done by twisting and rubbing the hands directly, which is troublesome and inconvenient to operate. In addition, the two winding coils connected by twisting and rubbing are also troublesome to disassemble and disconnect, which is not conducive to improving the efficiency of splicing and disassembling the two iron cores.

[0004] Although some inductors are equipped with special wiring mechanisms, these wiring mechanisms still require additional manual effort to connect and disconnect when the two-part spliced ​​core assembly is disassembled and assembled, and the operation is still cumbersome and inconvenient. Summary of the invention

[0005] In view of this, the present invention provides an inductor with a splicable iron core to solve the problem that although some inductors are equipped with special wiring mechanisms, these wiring mechanisms still require additional manual effort to connect and disconnect, and the operation is still relatively troublesome and inconvenient.

[0006] The technical solution proposed by the present invention is: an inductor with a spliced ​​core, specifically comprising: a base, a main core, a spliced ​​core and a frame, wherein the spliced ​​core is butt-jointed and plug-in assembled with the main core;

[0007] The main iron core and the spliced ​​iron core are both wound with winding coils; the skeleton as a whole is composed of a top disk and two upright support rods symmetrically welded to the outer circumference of the disk, and the spliced ​​iron core is lifted and slidably on the bottom of the disk by a spring; the main iron core and the spliced ​​iron core are both threadedly fastened with a mounting ring at one end that is butted against each other, wherein an ear plate is formed on the upper mounting ring, and a Z-shaped mounting rod is formed on the lower mounting ring; an electric pole is installed through the head end of the ear plate, and an electric pole is threadedly fastened to the head end of the Z-shaped mounting rod, one end of the two winding coils is connected to the electric pole through a soft wire for electrical conduction, and the other end is connected to the electric pole through a soft wire for electrical conduction; when the spliced ​​iron core is butt-jointed with the main iron core, the electric pole is connected to the electric pole for electrical conduction.

[0008] Furthermore, the main body core is threadedly fastened to the top of the base, and an annular positioning member is slidably mounted on the outer side of the base;

[0009] The outer edge of the circumference of the base is symmetrically provided with two slots, and the outer circle of the circumference of the base is symmetrically fixed with two U-shaped mounting sleeves, and the two U-shaped mounting sleeves and the two slots are arranged in a staggered manner;

[0010] The annular positioning member as a whole is composed of two semicircular rings and two symmetrically arranged arc-shaped connecting frames, and the head and tail ends of the two semicircular rings are fixedly connected together by the two arc-shaped connecting frames. The two semicircular rings are slidably matched with the two U-shaped mounting sleeves, and a tension spring is arranged between the arc-shaped connecting frame and the U-shaped mounting sleeve.

[0011] Furthermore, a rectangular positioning sleeve is fixedly provided at the bottom of the two vertical support rods, the two rectangular positioning sleeves are plugged into and matched with the two slots, and the head ends of the two semicircular rings are correspondingly plugged into and matched with the two rectangular positioning sleeves.

[0012] Furthermore, a vertically supported sliding column is hoisted at the bottom center of the skeleton disc, and the top end of the spliced ​​iron core is slidably matched with the sliding column through spring pushing.

[0013] Furthermore, the power connection rod is a sliding power connection rod, which is pushed by a spring and slides through the head end of the ear plate, and a circular power connection block is welded at the bottom of the sliding power connection rod. When the spliced ​​iron core and the main iron core are docked and combined, the circular power connection block is in contact with the head end of the power connection column.

[0014] Furthermore, the power connection rod is a power connection pole, which is threadedly fastened and penetrated through the head end of the ear plate. When the spliced ​​iron core and the main iron core are docked and combined, the two power connection poles are separated from each other up and down.

[0015] Furthermore, two ear blocks are fixedly arranged at intervals on the vertical support rod near one side of the ear plate, and a vertical drive shaft is slidably installed through the two ear blocks, and a V-shaped rod is welded to the bottom end of the vertical drive shaft;

[0016] The fixed sleeve of the part of the vertical drive shaft located between the two ear blocks is provided with a force ring, two arc-shaped spring pieces are symmetrically connected between the force ring and the upper ear block, and two arc-shaped elastic plates are symmetrically fixed at the bottom of the V-shaped rod;

[0017] Two hexagonal short shafts are symmetrically fixed on the narrow side of the vertical support rod close to the ear plate, two semicircular electrical connection sleeves are symmetrically slidably installed on the two hexagonal short shafts, and two connecting rods are symmetrically rotatably connected between the two semicircular electrical connection sleeves and the top of the vertical driving shaft.

[0018] Furthermore, when the spliced ​​core is connected to the main core, the two arc-shaped elastic plates are in contact with the base to drive the two semicircular electrical connection sleeves to slide towards each other and to abut and engage with the two electrical connection posts, thereby connecting the two electrical connection posts to conduct electricity.

[0019] The inductor with a splicable iron core provided by the present invention has the following beneficial effects:

[0020] In the present invention, the sliding connecting rod and the connecting column are mechanisms for connecting the two winding coils. The connection and disconnection of the two winding coils can be completed by simply sliding the sliding connecting rod up and down. Compared with the existing technology that lacks a special wiring mechanism and directly relies on hands to twist and rub the wiring, the operation is more convenient and efficient, which helps to improve the efficiency of assembling and disassembling the two iron cores.

[0021] In addition, when the spliced ​​iron core slides up and down and is disassembled and spliced ​​with the main iron core, the sliding power connection rod and the circular power connection block at its bottom can be driven to contact and separate from the power connection column, automatically connecting and disconnecting the two winding coils. Compared with the existing technology, it can save the trouble of additional manual operation of the wiring mechanism to connect and disconnect the two winding coils when disassembling and assembling the two iron cores. The operation is simple and time-saving, which helps to further improve the efficiency of splicing and disassembling the two iron cores.

[0022] In addition, the two crank slider mechanisms and the two connecting posts together constitute a mechanism for wiring the two winding coils. As a wiring mechanism, the two semicircular connecting sleeves thereon only apply lateral extrusion thrust to the two connecting posts and the spliced ​​iron core when they are abutted and engaged with the two connecting posts. This protects the spliced ​​iron core from the influence of the upward unstable thrust, helps to ensure the stability of the splicing of the two iron cores, and avoids increasing the butt gap between the two iron cores and the resulting hysteresis.

[0023] In addition, the two arc-shaped elastic plates can provide the spliced ​​iron core with room for continuous sliding down and docking with the main iron core. Compared with the method of setting the bottom end of the vertical drive shaft to directly abut against the base to drive the two semicircular power-connecting sleeves to abut and engage with the two power-connecting posts, it can avoid that when the two semicircular power-connecting sleeves are in pre-contact with the two power-connecting posts, the vertical drive shaft is limited and kept static in a state of hard abutment and contact between the bottom end and the base, which hinders the continuous sliding of the spliced ​​iron core and causes the spliced ​​iron core to be unable to dock and fit with the main iron core normally, which helps to ensure the normal and effective implementation of the automatic connection function of the two winding coils by the wiring mechanism.

[0045] 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 accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0046] Please refer to Figures 1 to 5 ; Example

[0047] The present invention provides an inductor with a spliced ​​core, comprising: a base 1, a U-shaped mounting sleeve 101, a slot 102, an annular positioning piece 2, an arc-shaped connecting frame 201, a main core 3, a spliced ​​core 4, an annular insulating pad 401, a plug post 402, a skeleton 5, an upright support rod 501, a hexagonal short axis 5011, a rectangular positioning sleeve 5012, an ear block 5013, a sliding column 502, an upright driving shaft 503, a force ring 5031, an arc-shaped spring piece 5032, a V-shaped rod 5033, an arc-shaped elastic plate 5034, a connecting rod 504, a semicircular power connection sleeve 505, an L-shaped slide plate 5051, a winding coil 6, a mounting ring 7, an ear plate 701, a Z-shaped mounting rod 702, a power connection column 703 and a sliding power connection rod 704, and the spliced ​​core 4 is butt-jointed and plug-in assembled with the main core 3;

[0048] Among them, winding coils 6 are wound on both the main iron core 3 and the spliced ​​iron core 4; the skeleton 5 is composed of a top disk and two upright support rods 501 symmetrically welded to the outer circle of the disk, and the spliced ​​iron core 4 is lifted and slidably on the bottom of the disk by spring pushing; the main iron core 3 and the spliced ​​iron core 4 are both threadedly fastened with a mounting ring 7 at one end of the butt joint, wherein an ear plate 701 is formed on the upper mounting ring 7, and a Z-shaped mounting rod 702 is formed on the lower mounting ring 7; an electric pole is installed through the head end of the ear plate 701, and an electric pole 703 is threadedly fastened to the head end of the Z-shaped mounting rod 702, one end of the two winding coils 6 is connected to the electric pole through a soft wire for electrical conduction, and the other end is connected to the electric pole 703 through a soft wire for electrical conduction; when the spliced ​​iron core 4 is butt jointed with the main iron core 3, the electric pole and the electric pole 703 are connected and electrically conductive.

[0049] Preferably, the main body core 3 is threadedly fastened to the top of the base 1, and an annular positioning member 2 is slidably mounted on the outer side of the base 1;

[0050] Two slots 102 are symmetrically provided on the outer circumference of the base 1, and two U-shaped mounting sleeves 101 are symmetrically fixed on the outer circumference of the base 1. The two U-shaped mounting sleeves 101 and the two slots 102 are arranged alternately, and the angle between them is 90°.

[0051] The annular positioning member 2 is composed of two semicircular rings and two symmetrically arranged arc-shaped connecting frames 201, and the head and tail ends of the two semicircular rings are fixedly connected together by two arc-shaped connecting frames 201. The two semicircular rings are slidably matched with two U-shaped mounting sleeves 101, and a tension spring is arranged between the arc-shaped connecting frame 201 and the U-shaped mounting sleeve 101.

[0052] Preferably, a rectangular positioning sleeve 5012 is fixedly provided at the bottom of the two vertical support rods 501, and the two rectangular positioning sleeves 5012 are plugged and matched with the two slots 102, and the head ends of the two semicircular rings are correspondingly plugged and matched with the two rectangular positioning sleeves 5012. Through the two semicircular rings, the annular positioning member 2 can plug and position the two rectangular positioning sleeves 5012 and the frame 5 with the base 1 together (refer to Figure 1 ), so that the spliced ​​core 4 is kept in the state of docking and combination with the main core 3, and the annular positioning member 2 rotates with the base 1 as the axis and is reset by pulling the tension spring. It only needs to be twisted forward and backward to drive the two semicircular rings and the two rectangular positioning sleeves 5012 to be plugged in and separated, and the skeleton 5 and the spliced ​​core 4 are tightened and loosened. Compared with the traditional inductor in which the skeleton 5 and the spliced ​​core 4 are set as a threaded fastening form, the spliced ​​core 4 is more convenient to tighten and disassemble.

[0053] Preferably, a vertical supporting slide column 502 is hoisted at the bottom center of the skeleton 5 disk, and the top of the spliced ​​core 4 is slidably matched with the slide column 502 through a spring push. After the skeleton 5 is positioned, the spring on the slide column 502 can push the spliced ​​core 4 and the main core 3 tightly together, reducing the docking gap between the two cores and the resulting hysteresis, which helps to ensure the magnetic flux of the two cores in the docking state and the overall operating efficiency of the inductor.

[0054] An annular insulating pad 401 is glued and fixed to the top of the spliced ​​iron core 4, and the bottom end of the spring on the sliding column 502 is in contact with the annular insulating pad 401; a vertical shaft hole is opened at the center of the main iron core 3, and a plug column 402 is welded at the bottom center of the spliced ​​iron core 4, and the plug column 402 is plugged into the vertical shaft hole.

[0055] Preferably, the power connecting rod is a sliding power connecting rod 704, which is pushed by a spring and slides through the head end of the ear plate 701, and a circular power connecting block is welded at the bottom of the sliding power connecting rod 704. When the spliced ​​iron core 4 and the main iron core 3 are docked and combined, the circular power connecting block abuts against the head end of the power connecting post 703, and the two winding coils 6 can be connected and energized. Then, the sliding power connecting rod 704 and the power connecting post 703 are the mechanisms for wiring the two winding coils 6 in the present invention. The connection and disconnection of the two winding coils 6 can be completed by the simple action of sliding the sliding power connecting rod 704 up and down, which is compared with the lack of a special The existing technology of the door wiring mechanism directly relies on the hands to twist and rub the wiring, which is convenient and efficient to operate, and helps to improve the efficiency of splicing and disassembling the two iron cores. When the spliced ​​iron core 4 slides up and down and is disassembled and spliced ​​with the main iron core 3, the sliding power connection rod 704 and the circular power connection block at its bottom can be driven to contact and separate from the power connection column 703, and automatically connect and disconnect the two winding coils 6. Compared with the existing technology, it can save the trouble of additional manual operation of the wiring mechanism to connect and disconnect the two winding coils 6 when disassembling and assembling the two iron cores. It is simple and time-saving to operate, and helps to further improve the efficiency of splicing and disassembling the two iron cores.

[0056] When the sliding connecting rod 704 is in contact with the connecting post 703, it is pushed back by the connecting post 703 to drive the spring compressed thereon to slide upward (refer to Figure 1 and Figure 2 ), at this time, the compressed spring will exert the upward reverse thrust after compression on the ear plate 701, the upper mounting ring 7 and the spliced ​​core 4, exerting an upward movement tendency on the spliced ​​core 4. This upward reverse thrust and movement tendency will counteract and offset a part of the downward pressing force exerted on the spliced ​​core 4 by the spring on the slide column 502, affecting the stability of the splicing of the two cores, and possibly expanding the joint gap between the two cores and the resulting hysteresis.

[0057] In view of the above problems, improvements are made on the basis of the first embodiment, as follows:

[0058] Embodiment 2, as Figures 6 to 10 As shown:

[0059] An inductor with a spliced ​​core also includes: a power connection rod is a power connection post 703, the power connection post 703 is threadedly fastened and penetrated through the head end of the ear plate 701, when the spliced ​​core 4 is docked and combined with the main core 3, the two power connection posts 703 are separated from each other up and down.

[0060] Preferably, two ear blocks 5013 are fixedly arranged at intervals on the vertical support rod 501 near the ear plate 701, and the vertical drive shaft 503 is slidably installed through the two ear blocks 5013, and a V-shaped rod 5033 is welded to the bottom end of the vertical drive shaft 503;

[0061] The part of the vertical drive shaft 503 between the two ear blocks 5013 is fixedly sleeved with a force ring 5031, and two arc-shaped spring pieces 5032 are symmetrically connected between the force ring 5031 and the upper ear block 5013, and two arc-shaped elastic plates 5034 are symmetrically fixed at the bottom of the V-shaped rod 5033;

[0062] Two hexagonal short shafts 5011 are symmetrically fixed on the narrow side of the vertical support rod 501 near the ear plate 701, and two semicircular power-connecting sleeves 505 are symmetrically slidably installed on the two hexagonal short shafts 5011. Two connecting rods 504 are symmetrically rotatably connected between the two semicircular power-connecting sleeves 505 and the top of the vertical drive shaft 503. The two connecting rods 504, the vertical drive shaft 503 and the two semicircular power-connecting sleeves 505 are connected together to form two crank slider mechanisms. Through these two mechanisms, the vertical drive shaft 503 can slide up and down to drive the two semicircular power-connecting sleeves 505 to slide towards each other and contact and separate from the two power-connecting posts 703, so as to connect and disconnect the two winding coils 6 (refer to Figure 6 and Figure 7 );

[0063] An L-shaped slide plate 5051 is threadedly fastened on the two semicircular electrical connection sleeves 505 . The two L-shaped slide plates 5051 are supported toward each other and slideably cooperate with the two hexagonal short shafts 5011 . The tail ends of the two connecting rods 504 are rotatably connected with the two L-shaped slide plates 5051 .

[0064] Preferably, when the spliced ​​core 4 is docked and combined with the main core 3, the two arc-shaped elastic plates 5034 are in contact with the base 1 to drive the two semicircular power-connecting sleeves 505 to slide close to each other and abut against and engage with the two power-connecting posts 703, so that the two power-connecting posts 703 are connected to conduct electricity. Through the power transmission of the two arc-shaped elastic plates 5034, when the skeleton 5 and the spliced ​​core 4 slide down and are inserted and spliced ​​with the main core 3, the vertical drive shaft 503 can be pushed back by the base 1 to slide upward, and the two semicircular power-connecting sleeves 505 are driven to slide close to each other and abut against and engage with the two power-connecting posts 703, so that the two winding coils 6 are automatically connected (refer to Figure 6 ), and when the skeleton 5 and the spliced ​​core 4 slide up and are disassembled from the main core 3, and the two arc-shaped elastic plates 5034 are disengaged from the base 1, the two arc-shaped spring plates 5032 can rebound and drive the vertical drive shaft 503 to slide downward and reset, control the two semicircular power connection sleeves 505 to slide away from each other and disengage from the two power connection posts 703, and automatically disconnect the two winding coils 6.

[0065] The two crank slider mechanisms and the two connecting posts 703 together constitute a mechanism for wiring the two winding coils 6. As a wiring mechanism, the two semicircular connecting sleeves 505 thereon only apply lateral extrusion thrust to the two connecting posts 703 and the spliced ​​core 4 when they are abutted and engaged with the two connecting posts 703. Compared with the first embodiment, the spliced ​​core 4 can be free from the influence of the upward unstable thrust, which helps to ensure the stability of the splicing and fitting of the two cores, and avoid increasing the butt gap between the two cores and the resulting hysteresis.

[0066] The vertical drive shaft 503 transmits the reverse thrust driving force through the elastic contact with the base 1 through two arc-shaped elastic plates 5034. In the process of the spliced ​​core 4 and the main core 3 sliding down and docking, when the two arc-shaped elastic plates 5034 are in advance pressed in contact with the base 1 and reversely drive the two semicircular power connection sleeves 505 and the two power connection posts 703 to abut and clamp together, and the spliced ​​core 4 and the main core 3 have not yet slid down and abutted against the spliced ​​core 4, the skeleton 5 can continue to slide down and press and bend the two arc-shaped elastic plates 5034 until the spliced ​​core 4 and the main core 3 abut against each other, so that the two arc-shaped elastic plates 5034 can provide continuous force for the spliced ​​core 4. Compared with setting the bottom end of the vertical drive shaft 503 to directly abut against the base 1 to drive the two semicircular power connection sleeves 505 to abut and engage with the two power connection posts 703, the movable margin for sliding down and docking with the main iron core 3 can avoid the vertical drive shaft 503 being abutted against the limit when the two semicircular power connection sleeves 505 are in pre-contact with the two power connection posts 703, and being kept stationary in a state of hard abutment and contact between the bottom end and the base 1, thereby hindering the continuous sliding of the spliced ​​iron core 4, causing the spliced ​​iron core 4 to be unable to dock and fit with the main iron core 3 normally, and helping to ensure the normal and effective implementation of the automatic connection function of the two winding coils 6 by the wiring mechanism.

[0067] A connecting ring is welded to the tail end of the lower connecting column 703. When the main iron core 3 is used alone, the head end of the upper winding coil 6 and the connecting ring are connected to the circuit as the input and output ends of the inductor; when the spliced ​​iron core 4 is docked and combined with the main iron core 3 for use, the head ends of the two winding coils 6 are connected to the circuit as the input and output ends of the inductor.

[0068] It is worth noting that, except for the main iron core 3 and the spliced ​​iron core 4 , the power connection column 703 and the sliding power connection rod 704 , all the components of the present invention are made of insulating materials.

[0069] Working principle of the first embodiment: When in use, the annular positioning member 2 can insert and position the two rectangular positioning sleeves 5012 and the frame 5 with the base 1 through the two semicircular rings (refer to Figure 1), so that the spliced ​​core 4 is kept in the state of docking and combination with the main core 3, and the annular positioning member 2 rotates with the base 1 as the axis and is reset by pulling the tension spring. It only needs to be twisted forward and backward to drive the two semicircular rings and the two rectangular positioning sleeves 5012 to plug and separate, and the skeleton 5 and the spliced ​​core 4 are tightened and loosened. After the skeleton 5 is positioned, the spring on the sliding column 502 can push the spliced ​​core 4 and the main core 3 tightly together, reducing the docking gap between the two cores and the resulting hysteresis;

[0070] When the spliced ​​core 4 is docked and combined with the main core 3, the circular power connection block comes into contact with the head end of the power connection post 703, so that the two winding coils 6 can be connected and energized. When the spliced ​​core 4 slides up and down and is disassembled and spliced ​​with the main core 3, the sliding power connection rod 704 and the circular power connection block at its bottom can be driven to contact and separate from the power connection post 703, automatically connecting and disconnecting the two winding coils 6.

[0071] Working principle of the second embodiment:

[0072] The two connecting rods 504, the vertical drive shaft 503 and the two semicircular power-connecting sleeves 505 are connected together to form two crank slider mechanisms. Through these two mechanisms, the vertical drive shaft 503 can slide up and down to drive the two semicircular power-connecting sleeves 505 to slide towards each other and contact and separate from the two power-connecting posts 703, thereby connecting and disconnecting the two winding coils 6.

[0073] Through the power transmission of the two arc-shaped elastic plates 5034, when the frame 5 and the spliced ​​core 4 slide down and are inserted and spliced ​​with the main core 3, the vertical drive shaft 503 can be pushed back by the base 1 to slide upward, and the two semicircular power connection sleeves 505 are driven to slide close to each other and abut against the two power connection posts 703, so that the two winding coils 6 are automatically connected (refer to Figure 6 ), and when the skeleton 5 and the spliced ​​core 4 slide up and are disassembled from the main core 3, and the two arc-shaped elastic plates 5034 are disengaged from the base 1, the two arc-shaped spring plates 5032 can rebound and drive the vertical drive shaft 503 to slide downward and reset, control the two semicircular power connection sleeves 505 to slide away from each other and disengage from the two power connection posts 703, and automatically disconnect the two winding coils 6;

[0074] The vertical drive shaft 503 transmits the reverse thrust driving force through the elastic contact with the base 1 through two arc-shaped elastic plates 5034. In the process of the spliced ​​iron core 4 and the main iron core 3 sliding down and docking, when the two arc-shaped elastic plates 5034 are in advance pressed into contact with the base 1 to reversely drive the two semicircular power connection sleeves 505 and the two power connection poles 703 to abut and be connected together, and the spliced ​​iron core 4 and the main iron core 3 have not yet slipped down and abutted against the spliced ​​iron core 4, the skeleton 5 can continue to slide down to press and bend the two arc-shaped elastic plates 5034 until the spliced ​​iron core 4 and the main iron core 3 abut against and fit together.
