Description

Technical Field

[0001] This utility model relates to the field of inductor technology, specifically a novel common-mode inductor. Background Technology

[0002] Common mode inductors are commonly used electronic components in the electrical field. Existing common mode inductors include a magnetic core, a coil, and a bracket. The bottom of the magnetic core is mounted on the bracket, which is fixed on a circuit board. The two ends of the coil are connected to the circuit board through pins fixed on the bracket.

[0003] The Chinese Patent Network discloses a common-mode inductor, publication number CN210245209U. Although the common-mode inductor can be mounted on the circuit board from the side of the magnetic core, reducing its size and improving its installation stability, and the electrodes are directly set at both ends of each coil, making its connection structure simple and easy to process, the connection part and winding part in this patent are integrated. This means that when installing two sets of coils, the two sets of coils may obstruct each other, making it inconvenient to install the coils, which is a significant drawback.

[0004] Therefore, a novel common-mode inductor is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a novel common-mode inductor.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel common-mode inductor, comprising:

[0008] Two symmetrically arranged connecting parts;

[0009] Two connecting holes are symmetrically provided on each of the two connecting parts;

[0010] Two opposing connection holes are connected to a winding part, and a coil is installed on the outer wall of the winding part;

[0011] A fixing component is provided on the outer wall of the connecting part, and the fixing component is used to fix the winding part.

[0012] Preferably, the fixing component includes a first threaded hole formed on the outer wall of the connecting part, and the first threaded hole communicates with the connecting hole;

[0013] A second threaded hole is provided on the outer wall of the winding part, and threaded parts are internally connected to the first threaded hole and the second threaded hole.

[0014] Preferably, a rotating bar is fixed to one end of the threaded component.

[0015] Preferably, the outer wall of the winding portion is symmetrically provided with two limiting portions, which are respectively located at both ends of the coil.

[0016] Preferably, a limiting groove is provided on the outer wall of the winding part, and a plurality of locking holes are provided at the bottom of the limiting groove;

[0017] Both of the inner walls of the limiting parts are fixed with limiting blocks located inside the limiting grooves;

[0018] One end of the limiting block is fixed with a connecting ear, the top of the connecting ear has a through hole, a locking rod is movably inserted in the through hole, the top of the locking rod is fixed with a pull plate, and the bottom of the locking rod is engaged in one of the locking holes.

[0019] Preferably, a spring is provided on the outer wall of the lever, one end of the spring is fixed to the pull plate, and the other end of the spring is fixed to the connecting lug.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention employs a separate design for the connecting part and the winding part, allowing the coil to be installed separately onto the outer walls of the two winding parts. The winding parts are then inserted into the connecting holes, and the threaded components are connected to the first and second threaded holes via a swivel, thus connecting and fixing the connecting part and the winding part. Compared to existing designs, this invention, by separating the connecting part and the winding part and installing the coils separately onto the outer walls of the winding parts before connecting the connecting part and the winding part, prevents the coils from interfering with each other during installation, thereby facilitating coil installation.

[0022] This utility model has two limiting parts symmetrically arranged on the outer wall of the winding part. The two limiting parts are respectively located at both ends of the coil. Therefore, the coil can be limited by the two limiting parts, thereby improving the installation stability of the coil.

[0023] Furthermore, by pulling the pull plate, the pull plate drives the locking rod to move. After the bottom of the locking rod disengages from one of the locking holes, it can drive the two limiting parts to move, thereby adjusting the distance between the two limiting parts. After the distance between the two limiting parts is adjusted, the pull plate is released. At this time, the locking rod will be driven to move under the action of the spring. After the bottom of the locking rod is engaged in one of the locking holes, the two limiting parts can be fixed. Compared with the existing ones, this utility model can adjust the distance between the two limiting parts, so that it can meet the use of coils of different sizes, and has higher practicality.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] Example 1:

[0032] Please see Figure 1-3 This utility model provides a technical solution: To achieve the above objectives, this utility model provides the following technical solution: A novel common-mode inductor, comprising: two symmetrically arranged connecting portions 1; two symmetrically opened connecting holes 2 on each of the two connecting portions 1; a winding portion 3 connected to the two opposing connecting holes 2, and a coil 4 installed on the outer wall of the winding portion 3; a fixing component provided on the outer wall of the connecting portion 1, the fixing component being used to fix the winding portion 3, the fixing component including a first threaded hole 17 opened on the outer wall of the connecting portion 1, the first threaded hole 17 communicating with the connecting holes 2; a second threaded hole 5 opened on the outer wall of the winding portion 3, a threaded component 6 being threadedly connected to the first threaded hole 17 and the second threaded hole 5, and a rotating bar 7 fixed to one end of the threaded component 6.

[0033] Specifically, this utility model adopts a separate design for the connecting part 1 and the winding part 3, so the coil 4 can be installed separately onto the outer wall of the two winding parts 3. Then, the winding part 3 is inserted into the connecting hole 2, and the threaded part 6 is threaded into the first threaded hole 17 and the second threaded hole 5 by the rotating bar 7. This connects and fixes the connecting part 1 and the winding part 3. Compared with the existing ones, this utility model adopts a separate design for the connecting part 1 and the winding part 3, and then installs the coil 4 separately onto the outer wall of the winding part 3 before connecting the connecting part 1 and the winding part 3. This prevents the coil 4 from interfering with each other during installation, thereby facilitating the installation of the coil 4.

[0034] Example 2:

[0035] Please see Figure 1 , 3 4. This utility model provides a technical solution: a novel common-mode inductor, wherein two limiting parts 8 are symmetrically arranged on the outer wall of the winding part 3, and the two limiting parts 8 are respectively located at both ends of the coil 4. A limiting groove 9 is opened on the outer wall of the winding part 3, and multiple locking holes 16 are opened at the bottom of the limiting groove 9. A limiting block 10 located inside the limiting groove 9 is fixed on the inner wall of each of the two limiting parts 8. A connecting ear 11 is fixed at one end of the limiting block 10, and a through hole 12 is opened at the top of the connecting ear 11. A locking rod 13 is movably inserted in the through hole 12. A pull plate 14 is fixed at the top of the locking rod 13, and the bottom of the locking rod 13 is locked in one of the locking holes 16. A spring 15 is provided on the outer wall of the locking rod 13. One end of the spring 15 is fixed to the pull plate 14, and the other end of the spring 15 is fixed to the connecting ear 11.

[0036] Specifically, this utility model provides two limiting parts 8 symmetrically arranged on the outer wall of the winding part 3. The two limiting parts 8 are respectively located at both ends of the coil 4. Therefore, the coil 4 can be limited by the two limiting parts 8, thereby improving the installation stability of the coil 4.

[0037] Furthermore, by pulling the pull plate 14, the pull plate 14 drives the locking rod 13 to move. After the bottom of the locking rod 13 disengages from one of the locking holes 16, it can drive the two limiting parts 8 to move, thereby adjusting the distance between the two limiting parts 8. After the distance between the two limiting parts 8 is adjusted, the pull plate 14 is released. At this time, the locking rod 13 will be driven to move under the action of the spring 15. After the bottom of the locking rod 13 is engaged in one of the locking holes 16, the two limiting parts 8 can be fixed. Compared with the existing ones, this utility model can adjust the distance between the two limiting parts 8, so that it can meet the use of coils 4 of different sizes, and has higher practicality.

[0038] Working principle:

[0039] Firstly, by adopting a separate design for the connecting part 1 and the winding part 3, the coil 4 can be installed separately onto the outer wall of the two winding parts 3. Then, the winding part 3 is inserted into the connecting hole 2, and the threaded part 6 is threaded into the first threaded hole 17 and the second threaded hole 5 by the rotating bar 7. This connects and fixes the connecting part 1 and the winding part 3. Compared with the existing design, this utility model adopts a separate design for the connecting part 1 and the winding part 3, installs the coil 4 separately onto the outer wall of the winding part 3, and then connects the connecting part 1 and the winding part 3. This prevents the coil 4 from interfering with each other during installation, thereby facilitating the installation of the coil 4.

[0040] Secondly, by symmetrically providing two limiting parts 8 on the outer wall of the winding part 3, and the two limiting parts 8 being respectively provided at both ends of the coil 4, the coil 4 can be limited under the action of the two limiting parts 8, thereby improving the installation stability of the coil 4.

[0041] Finally, by pulling the pull plate 14, the pull plate 14 drives the locking rod 13 to move. After the bottom of the locking rod 13 disengages from one of the locking holes 16, it can drive the two limiting parts 8 to move, thereby adjusting the distance between the two limiting parts 8. After the distance between the two limiting parts 8 is adjusted, the pull plate 14 is released. At this time, the locking rod 13 will be driven to move under the action of the spring 15. After the bottom of the locking rod 13 is engaged in one of the locking holes 16, the two limiting parts 8 can be fixed. Compared with the existing ones, this utility model can adjust the distance between the two limiting parts 8, so that it can meet the use of coils 4 of different sizes, and has higher practicality.
