Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to an adjustable inductor structure for high-frequency transformers. Background Technology

[0002] A high-frequency transformer is a transformer operating at frequencies between several kilohertz and several hundred megahertz. It achieves voltage transformation by adjusting the coil turns ratio to meet the different voltage requirements of various devices. It converts mains voltage into the specific DC voltage required by electronic equipment, efficiently transmitting power to the load and ensuring normal operation. It possesses unique characteristics, wide applications, specific structures and operating principles, and multiple classification methods. Existing high-frequency transformers use a fixed, non-adjustable inductor structure to ensure stable operation. This results in the fixed inductor being unable to flexibly adapt to the varying load requirements under different operating conditions, making it difficult to match diverse loads. Therefore, this invention proposes an adjustable inductor structure for high-frequency transformers. Utility Model Content

[0003] The purpose of this invention is to address the problem that in the background technology, the inductor structure of high-frequency transformers is fixed and cannot be adjusted in order to ensure stable operation. This results in the fixed inductor being unable to flexibly adapt to the different needs brought about by load changes under different operating conditions, making it difficult to match diverse loads. Therefore, this invention proposes an adjustable inductor structure for high-frequency transformers.

[0004] The technical solution of this utility model is as follows: an adjustable inductor structure for a high-frequency transformer, comprising: a set of bases for support, an iron frame fixedly disposed on the upper surface of the bases, and a coil wound around the outer wall of the iron frame; an iron core disposed through the iron frame, and an electromagnetic adjustment component for adjusting the permeability of the iron core disposed inside the iron frame.

[0005] Optionally, the electromagnetic adjustment assembly includes guide frames fixedly mounted on both sides of the iron core, with fixed blocks fixedly mounted on opposite sides of the guide frames, and guide rods fixedly mounted on both sides of the fixed blocks. Baffles are movably sleeved on the outer walls of the guide rods, and the baffles are slidably mounted inside the guide frames. A spring is sleeved on the outer wall of the guide rod, with one end of the spring fixedly connected to the fixed block and the other end of the spring fixedly connected to the baffle.

[0006] Optionally, the electromagnetic adjustment assembly further includes a push block slidably disposed between the baffles, a threaded rod rotatably disposed on the upper surface of the push block, a support frame being threadedly sleeved on the outer wall of the threaded rod, and the lower end of the support frame being fixedly connected to the iron frame.

[0007] Optionally, a conductive plate is embedded in the upper surface of the base, and multiple connecting terminals are fixedly connected to the bottom surface of the conductive plate. The connecting terminals penetrate the base and extend to the outside, and terminal connection points are provided on the upper surface of the conductive plate.

[0008] Optionally, coil terminals are provided at both ends of the coil, and one end of the coil terminal is soldered to the terminal connection point with solder wire.

[0009] Optionally, a mounting hole groove is provided on one side of the base.

[0010] Optionally, the base has multiple heat dissipation slots on its side.

[0011] Optionally, the sliding surfaces of the baffle and the push block are respectively inclined.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes a rotating threaded rod to drive a pusher block, which in turn moves a baffle horizontally to both sides within the guide frame. Guided by a guide rod and spring, the baffle blocks the sides of the iron core, thus obstructing the magnetic field and creating magnetic reluctance. This alters the position of the magnetic field, demonstrating remarkable flexibility in handling complex and varied operating conditions. Whether under light, full, or overload conditions, the high-frequency transformer can precisely match the current load requirements by conveniently adjusting the inductance, maintaining stable operation and significantly expanding its applicability while ensuring the continuity and reliability of power transmission.

[0027] Example

[0028] like Figure 1 and Figure 2As shown in the figure, an adjustable inductor structure for a high-frequency transformer proposed by the present utility model includes a group of bases 1 for support, and the bases 1 are symmetrically arranged. The upper surface of the base 1 is fixedly provided with an iron frame 2, which can stably support the iron frame 2. A coil 3 is wound around the outer wall of the iron frame 2, and a magnetic field can be generated around it after being energized. A core 4 is disposed through the inside of the iron frame 2, and an electromagnetic adjustment component 5 for adjusting the magnetic permeability of the core 4 is arranged inside the iron frame 2, which is convenient for adjusting the inductor of the transformer.

[0029] As Figure 3 and Figure 4 shown in the figure, the electromagnetic adjustment component 5 includes guiding frames 51 fixedly arranged on both sides of the core 4, and the guiding frames 51 are symmetrically arranged. Fixed blocks 52 are respectively fixedly arranged on the opposite surfaces of the guiding frames 51. Guide rods 53 are fixedly arranged on both sides of the fixed blocks 52. Flap pieces 54 are respectively movably sleeved on the outer walls of the guide rods 53, which is convenient for guiding the flap pieces 54 to move stably horizontally, and the flap pieces 54 are slidably arranged inside the guiding frames 51. A spring 55 is sleeved on the outer wall of the guide rod 53. One end of the spring 55 is fixedly connected to the fixed block 52, and the other end of the spring 55 is fixedly connected to the flap piece 54, which is convenient for pulling the flap piece 54 to reset.

[0030] Furthermore, the electromagnetic adjustment component 5 further includes a push block 56 slidably arranged between the flap pieces 54, and the push block 56 is arranged in a "冂" - shaped structure, which is convenient for simultaneously pushing the flap pieces 54 to move horizontally. A threaded rod 57 is rotatably arranged on the upper surface of the push block 56. A support frame 58 is threadedly sleeved on the outer wall of the threaded rod 57, and the support frame 58 is arranged in a "冂" - shaped structure. The lower end of the support frame 58 is fixedly connected to the iron frame 2, which is convenient for driving the push block 56 to push the flap pieces 54 to move horizontally relative to each other or in the opposite direction.

[0031] As Figure 1 and Figure 2 shown in the figure, a conductive plate 6 is embedded on the upper surface of the base 1. A plurality of connection terminals 7 are fixedly connected to the bottom surface of the conductive plate 6, and the connection terminals 7 penetrate through the base 1 and extend to the outside, which is convenient for connecting with an external circuit. Terminal connection points 8 are arranged on the upper surface of the conductive plate 6, which is convenient for connecting with the coil 3.

[0032] Secondly, coil terminals 9 are respectively arranged at both ends of the coil 3. One end of the coil terminal 9 is soldered to the terminal connection point 8 with tin wire to ensure the stability of the connection.

[0033] Furthermore, an installation hole groove 10 is formed on one side of the base 1, which is convenient for stably installing the base 1.

[0034] In addition, a plurality of heat dissipation grooves 11 are formed on the side of the base 1, which is convenient for dissipating the heat of the base 1 and improving the service life.

[0035] Finally, the sliding surfaces of the baffle 54 and the push block 56 are inclined to facilitate the push block 56 to push the baffle 54 to move horizontally relative to or opposite to each other.

[0036] The working principle of this embodiment is as follows: The entire device is supported by a set of bases 1, and the iron frame 2 fixed on its upper surface provides a stable installation foundation for subsequent components. The coil 3 wound on the outer wall of the iron frame 2 is the key part for realizing the mutual conversion of electrical energy and magnetic energy. When current passes through the coil 3, a magnetic field is generated around it. The iron core 4 that runs through the inside of the iron frame 2 plays an important role in enhancing the magnetic permeability and concentrating magnetic lines of force during the operation of the transformer, which can greatly improve the efficiency of electromagnetic conversion.

[0037] In the electromagnetic adjustment assembly 5, the guide frame 51 is fixed on both sides of the iron core 4, providing guidance and support for other components. The fixing block 52 is fixed to the opposite side of the guide frame 51. The guide rod 53 extends from both sides of the fixing block 52. The baffle 54 is movably sleeved on the outer wall of the guide rod 53 and can slide inside the guide frame 51. The spring 55 is sleeved on the guide rod 53, with one end fixed to the fixing block 52 and the other end fixed to the baffle 54. In the initial state, the elastic force of the spring 55 keeps the baffle 54 in a certain position.

[0038] Furthermore, the push block 56 is slidably disposed between the baffles 54, and its sliding surface is inclined. When the threaded rod 57 is rotated, since the threaded rod 57 is threadedly engaged with the support frame 58, the threaded rod 57 rotates and drives the push block 56 to move up and down. When the push block 56 moves upward, its inclined surface contacts the inclined surface of the baffle 54, which pushes the baffle 54 to move horizontally along the guide rod 53. The spring 55 pulls the baffle 54 to move horizontally relative to each other, thereby reducing the obstruction of the baffle 54 on both sides of the iron core 4. Conversely, when the push block 56 moves downward, the push block 56 pushes the baffle 54 to move horizontally in the opposite direction. The baffle 54 is guided by the guide rod 53, making the horizontal opposite movement more stable, thereby increasing the obstruction of the baffle 54 on both sides of the iron core 4. This changes the magnetic field distribution around the iron core 4, thereby adjusting the magnetic permeability of the iron core 4, and ultimately achieving the adjustment of the inductance.

[0039] In terms of electrical connection, the conductive plate 6 embedded in the upper surface of the base 1 bears the important responsibility of current transmission. Multiple connection terminals 7 on its bottom surface extend through the base 1 to the outside, facilitating connection with external circuits. The terminal connection points 8 on the upper surface of the conductive plate 6 are used to connect the coil 3. The coil terminals 9 at both ends of the coil 3 are soldered to the terminal connection points 8 with solder wire, ensuring that current can flow smoothly into and out of the coil 3, achieving efficient transmission of electrical energy.

[0040] In addition, the mounting hole slot 10 opened on one side of the base 1 facilitates the installation of the entire device, enabling it to be securely installed in the required equipment; while the multiple heat dissipation slots 11 opened on the side of the base 1 can dissipate the heat generated during the operation of the transformer in a timely manner, ensuring the stable operation of the device and avoiding performance degradation or damage due to overheating.

[0041] In summary, this adjustable inductance structure for high-frequency transformers achieves efficient and stable transformer inductance adjustment by flexibly controlling the permeability of the iron core 4 through the electromagnetic adjustment component 5, combined with reasonable electrical connections and heat dissipation design.

[0042] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
