Description

Technical Field

[0001] The utility model relates to the technical field of magnetic cores, and more specifically, to a magnetic core without a middle column. Background Art

[0002] A magnetic core without a middle column is usually called a toroidal magnetic core or an open magnetic core. It is a special type of magnetic core. Different from traditional toroidal magnetic cores or E-shaped and U-shaped magnetic cores with a central column, this magnetic core has no middle column, and magnetic flux flows along the circumferential path around the magnetic core. The design of the magnetic core without a middle column can select different materials and sizes according to the requirements of specific applications to achieve the best electrical and magnetic properties.

[0003] When the existing magnetic cores without a middle column are in use, most of them directly wind coils around the magnetic core. The coils will exert a force on the magnetic core, causing the magnetic core to deform, reducing the magnetic properties of the magnetic core. At the same time, uneven winding will occur during coil winding, resulting in uneven distribution of magnetic flux in the magnetic circuit, thus affecting the performance and efficiency of the device. In addition, when one coil is damaged, it will affect other coils, reducing the practicability of the device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a magnetic core without a middle column to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides a magnetic core without a middle column, which includes a base. A magnetic core body is arranged inside the base. Outer sides of both sides of the magnetic core body are provided with outer shells. The outer shells are composed of an installation ring, a docking ring, and a connection ring. A first fixing plate is fixedly connected to the lower sides of the installation ring and the connection ring. A first docking plate is fixedly connected to the upper sides of the docking ring and the connection ring. The first fixing plate and the first docking plate are rotatably connected. A plurality of partition plates are sleeved outside the installation ring, the docking ring, and the connection ring. One side of the partition plate is rotatably connected, and a disassembly mechanism is arranged at the other end of the partition plate. The disassembly mechanism is used to disassemble the partition plate. An installation mechanism is arranged at one end of the installation ring and the docking ring away from the first docking plate. The installation mechanism is used to install the magnetic core body.

[0006] As a further improvement of this technical solution, the disassembly mechanism includes a first fixing block and a second fixing block. The first fixing block and the second fixing block are respectively fixedly connected to one side of two partition plates. Two moving rods are slidably connected inside the second fixing block. Springs are fixedly connected to adjacent ends of the moving rods. Two card slots adapted to the moving rods are opened inside the first fixing block.

[0007] As a further improvement of the technical solution, the installation mechanism includes a second docking plate and a second fixing plate. The second docking plate is fixedly connected to the upper sides of the docking ring and the connecting ring. The second fixing plate is fixedly connected to the lower sides of the installation ring and the connecting ring. A groove is formed inside the second fixing plate. Elastic pieces are fixedly connected to both sides inside the groove. A plug rod is fixedly connected to the lower side of the second docking plate, and the plug rod is arranged inside the groove. A convex block is fixedly connected inside the two elastic pieces, and the convex block is located on both sides of the plug rod.

[0008] As a further improvement of the technical solution, two circular grooves are formed on the outer side of the plug rod. The circular grooves correspond to the positions of the convex blocks, and the convex blocks are clamped inside the circular grooves.

[0009] As a further improvement of the technical solution, two wire pins are inserted inside the base, and one side of the wire pins is fixedly connected to one side of the partition plate.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: By pulling up the second docking plate upward, the fixing of the convex block on the plug rod is released. The magnetic core body is placed inside the housing. The coil is sequentially wound around the magnetic core body through the spaces between the installation ring, the docking ring, and the connecting ring. The provided housing prevents the coil from exerting a force on the magnetic core body, causing the magnetic core body to deform, and improves the magnetic performance of the magnetic core body. At the same time, by pressing the two moving rods to squeeze the springs, the fixing of the first fixing block is released, and the partition plate is disassembled. The multiple partition plates provided are sleeved on the housing, making the coil winding more uniform, and at the same time playing an isolation effect between the coils, preventing one coil from being damaged and affecting other coils, and improving the practicability of the device.

[0022] Embodiment 1

[0023] Please refer to Figures 1 - 5As shown in the figure, this embodiment provides a magnetic core without a middle column, including a base 1. Inside the base 1, a magnetic core body 12 is arranged. On both outer sides of the magnetic core body 12, there are outer shells. The outer shells are composed of a mounting ring 14, a docking ring 15, and a connecting ring 16. On the lower sides of the mounting ring 14 and the connecting ring 16, there is a first fixing plate 25 fixedly connected. On the upper sides of the docking ring 15 and the connecting ring 16, there is a first docking plate 24 fixedly connected. The first fixing plate 25 and the first docking plate 24 are rotatably connected. A plurality of partition plates 13 are sleeved outside the mounting ring 14, the docking ring 15, and the connecting ring 16. One side of the partition plate 13 is rotatably connected, and the other end of the partition plate 13 is provided with a disassembly mechanism 3. The disassembly mechanism 3 is used to disassemble the partition plate 13, facilitating the addition of partition plates 13 as needed. The partition plates 13 play an isolation effect between the coils. At one end of the mounting ring 14 and the docking ring 15 away from the first docking plate 24, there is an installation mechanism 2. The installation mechanism 2 is used to install the magnetic core body 12. By arranging the outer shell, the coil is tightly wound on the surface of the outer shell, and at the same time, the coil does not exert a force on the magnetic core body 12, avoiding deformation of the magnetic core body 12 and improving the magnetic performance of the magnetic core body 12.

[0024] The disassembly mechanism 3 includes a first fixing block 31 and a second fixing block 32. The first fixing block 31 and the second fixing block 32 are respectively fixedly connected to one side of two partition plates 13. Inside the second fixing block 32, two moving rods 33 are slidably connected. The adjacent ends of the moving rods 33 are fixedly connected with springs 34. Inside the first fixing block 31, there are two card slots adapted to the moving rods 33. By pressing the two moving rods 33 simultaneously to compress the springs 34, the moving rods 33 are moved into the second fixing block 32, releasing the fixation of the first fixing block 31. Pulling the first fixing block 31 to open the partition plate 13 realizes the disassembly of the partition plate 13. By arranging a plurality of partition plates 13 sleeved on the outer shell, the coil is wound more evenly, playing an isolation effect between the coils, avoiding damage to one coil affecting other coils, and improving the practicability of the device.

[0025] The installation mechanism 2 includes a second docking plate 21 and a second fixing plate 22. The second docking plate 21 is fixedly connected to the upper sides of the docking ring 15 and the connecting ring 16. The second fixing plate 22 is fixedly connected to the lower sides of the installation ring 14 and the connecting ring 16. A groove is formed inside the second fixing plate 22. Elastic pieces 27 are fixedly connected to both sides inside the groove. A plug rod 23 is fixedly connected to the lower side of the second docking plate 21. Two circular grooves are formed on the outer side of the plug rod 23. The circular grooves correspond to the positions of the convex blocks 26, and the convex blocks 26 are clamped in the circular grooves. The plug rod 23 is arranged inside the groove. The convex blocks 26 are fixedly connected to the inside of the two elastic pieces 27. The convex blocks 26 are located on both sides of the plug rod 23. Pull the second docking plate 21 upward. The second docking plate 21 drives the plug rod 23 to move upward, so that the convex blocks 26 are separated from the inside of the circular grooves, releasing the fixation of the convex blocks 26 on the plug rod 23. Rotate the second docking plate 21 to open the docking ring 15. Place the magnetic core body 12 inside the installation ring 14 and the docking ring 15. On the contrary, close the second docking plate 21 and insert the plug rod 23 into the second fixing plate 22. The plug rod 23 squeezes the elastic pieces 27 to move to both sides until the convex blocks 26 are clamped with the plug rod 23. Then wind the coil through the spaces between the installation ring 14, the docking ring 15 and the connecting ring 16 around the magnetic core body 12 in sequence. Through the provided outer shell, the coil is tightly wound on the surface of the outer shell. At the same time, the coil does not exert force on the magnetic core body 12, avoiding deformation of the magnetic core body 12 and improving the magnetic performance of the magnetic core body 12.

[0026] Two wire pins 11 are inserted into the base 1. One side of the wire pins 11 is fixedly connected to one side of the partition 13. The provided base 1 plays a role in supporting the magnetic core body 12, avoiding the position deviation of the magnetic core body 12 and improving the stability of the device.

[0027] When the non-center-column magnetic core of this embodiment is specifically used, pull the second docking plate 21 upward. The second docking plate 21 drives the plug rod 23 to move upward, so that the convex blocks 26 are separated from the inside of the circular grooves, releasing the fixation of the convex blocks 26 on the plug rod 23. Rotate the second docking plate 21 to open the docking ring 15. Place the magnetic core body 12 inside the installation ring 14 and the docking ring 15. On the contrary, close the second docking plate 21 and insert the plug rod 23 into the second fixing plate 22. The plug rod 23 squeezes the elastic pieces 27 to move to both sides until the convex blocks 26 are clamped with the plug rod 23. Then wind the coil through the spaces between the installation ring 14, the docking ring 15 and the connecting ring 16 around the magnetic core body 12 in sequence. Through the provided outer shell, the coil is tightly wound on the surface of the outer shell. At the same time, the coil does not exert force on the magnetic core body 12, avoiding deformation of the magnetic core body 12 and improving the magnetic performance of the magnetic core body 12;

[0028] Press the two moving rods 33 simultaneously to squeeze the spring 34, causing the moving rods 33 to move into the interior of the second fixed block 32, releasing the fixation on the first fixed block 31. Pull the first fixed block 31 to open the partition 13, achieving the disassembly of the partition 13. By arranging multiple partitions 13 sleeved on the outer shell, the coils are wound more evenly, further improving the performance of the device, achieving an isolation effect between the coils, avoiding the damage of one coil affecting other coils, and improving the practicability of the device.
