Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency transformer equipment, in particular to a skeleton for an assembled high-frequency transformer. Background Art

[0002] In the design of high-frequency transformers, the skeleton is a crucial component. The main functions of the high-frequency transformer skeleton are to provide support and positioning for the windings, and at the same time optimize the magnetic circuit and insulation. However, the use of an assembled structure makes the repair and maintenance of the transformer more convenient. Damaged components can be replaced or repaired individually without disassembling the entire transformer;

[0003] For traditional skeletons of assembled high-frequency transformers, usually after the windings are installed on the skeleton, an insulating glue (such as epoxy resin) is applied to the contact surface between the windings and the skeleton. After the insulating glue is applied, it undergoes a certain curing process, changing from a liquid state to a solid state, forming a firm bonding layer that can firmly fix the windings on the skeleton and prevent the windings from moving or loosening during the operation of the transformer;

[0004] Traditional skeletons of assembled high-frequency transformers have the following problems: During the operation of the transformer, the insulating glue may thermally expand or contract due to temperature changes, which may cause cracks or peeling in the bonding layer between the windings and the skeleton, affecting the stability of the connection between the windings and the skeleton. Moreover, once the glue is cured, a firm bonding layer is formed between the windings and the skeleton of the transformer, making the disassembly work very difficult when the windings need to be repaired or replaced. For this reason, we propose a skeleton for an assembled high-frequency transformer. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a skeleton for an assembled high-frequency transformer, which can ensure the stable connection of the assembled high-frequency transformer skeleton, reduce the maintenance requirements, and at the same time improve the convenience of adjustment and maintenance, and can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A skeleton for an assembled high-frequency transformer, including a winding cylinder, and blocking plates are respectively installed at the left and right ends of the winding cylinder, including a fixing mechanism;

[0007] Fixing mechanism: It includes cams, connecting columns, extrusion blocks, connecting holes, and second sliding holes. The connecting holes are all opened on the inner wall of the wire blocking plate connection port, and the second sliding holes are all opened at the left and right ends of the inner wall of the winding cylinder. The inner walls of the second sliding holes are all slidably connected with connecting columns, and the connecting columns are all fitted and installed with the adjacent connecting holes. One end of the connecting column close to the center of the winding cylinder is fixedly connected with an extrusion block. The cams are all rotatably connected to the left and right ends inside the winding cylinder. The cams on the same side are all fitted and installed with the adjacent extrusion blocks, which can ensure the stable connection of the assembled high-frequency transformer skeleton, reduce the maintenance requirements, and improve the convenience of adjustment and maintenance at the same time, thereby improving the overall efficiency and reliability of the high-frequency transformer.

[0008] Furthermore, it also includes support seats. The support seats are all fixedly connected to the bottom end of the wire blocking plate, and evenly distributed pins are welded on the lower surface of the support seats to ensure the stability and reliability of electrical connection.

[0009] Furthermore, the fixing mechanism also includes second springs. The second springs are all fixedly connected to the upper surface of the extrusion block and the adjacent end of the inner wall of the winding cylinder, and the second springs are all sleeved on the outer surface of the connecting column to ensure that the connecting column can smoothly retract to the appropriate position when the pressure is released.

[0010] Furthermore, the fixing mechanism also includes a knob and a rotating shaft. The rotating shaft is rotatably connected between the left and right inner walls of the winding cylinder. The left and right ends of the rotating shaft are both fixedly connected to the inside of the adjacent cams. The left end of the rotating shaft is fixedly connected with a knob to drive the fixing mechanism.

[0011] Furthermore, it also includes a positioning mechanism. The positioning mechanism includes first sliding holes, positioning columns, and positioning holes. The first sliding holes are respectively opened at the upper and lower ends of the right side surface of the knob. The inner walls of the first sliding holes are all slidably connected with positioning columns. The number of the positioning holes is four, and the four positioning holes are all opened on the left side surface of the winding cylinder. The positioning holes are all fitted and installed with the laterally adjacent positioning columns, so that it can accurately maintain or adjust the position during rotation.

[0012] Furthermore, the positioning mechanism also includes first springs. The first springs are all fixedly connected to the upper and lower ends of the right side surface of the knob and the adjacent end of the left side surface of the winding cylinder, and the first springs are all sleeved on the outer surface of the positioning column to help the knob return to the initial position or other preset positions.

[0013] Furthermore, chamfer structures are provided at the right end of the positioning column and the edge of the positioning hole to improve the smoothness during positioning.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The skeleton for the assembled high-frequency transformer has the following advantages:

[0015] 1. By rotating the knob, the positioning post is driven to move out of the corresponding positioning hole, and the spring is compressed. As a result, the knob can rotate freely. The rotation of the knob drives the rotating shaft, and the rotating shaft drives the cam to rotate. The cam presses the extrusion block, causing the connecting post to insert into the connecting hole, fixing the wire retaining plate on the winding bobbin. Subsequently, the positioning post locks the knob in the new positioning hole, ensuring the stable connection of the wire retaining plate, thereby ensuring the stable connection between the winding and the skeleton all the time, reducing the maintenance and repair required due to unstable connection, and significantly improving the performance and reliability of the skeleton for high-frequency transformers.

[0016] 2. When adjustment or maintenance is needed, rotate the knob in the reverse direction to unlock it, causing the positioning post to disengage from the positioning hole. This makes the eccentric end of the cam move away from the extrusion block. The release of this pressure causes the connecting post to withdraw from the connecting hole under the action of the second spring, and the wire retaining plate is released from fixation. The wire retaining plate and the winding bobbin can be easily removed, enabling more convenient and rapid adjustment or maintenance of the skeleton for assembled high-frequency transformers, avoiding unnecessary damage to the skeleton for assembled high-frequency transformers during adjustment or disassembly, and making the adjustment and maintenance operations more convenient and flexible.

DETAILED DESCRIPTION OF THE EMBODIMENTS

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

[0024] Please refer to Figures 1-5 , this embodiment provides a technical solution: a bobbin for an assembled high-frequency transformer, including a winding cylinder 1, wire blocking plates 2 are respectively installed at the left and right ends of the winding cylinder 1. Copper wires or aluminum wires are wound around the winding cylinder 1, and then the connection ports on the wire blocking plates 2 are installed at the left and right ends of the winding cylinder 1. It also includes support seats 5, the support seats 5 are fixedly connected to the bottom ends of the wire blocking plates 2, and evenly distributed pins 6 are welded on the lower surfaces of the support seats 5. After assembly, the copper wires are connected to the pins 6 to ensure that all electrical connections are correct, and check the stability and functionality of the overall structure to confirm that the performance of the transformer meets the requirements, including a fixing mechanism 4;

[0025] Fixing mechanism 4: It includes a cam 42, a connecting column 43, a pressing block 44, a connecting hole 46, and a second sliding hole 47. The connecting holes 46 are all opened on the inner wall of the connecting port of the wire blocking plate 2. The second sliding holes 47 are all opened at the left and right ends of the inner wall of the winding cylinder 1. The inner walls of the second sliding holes 47 are all slidably connected with the connecting columns 43. The connecting columns 43 are all installed in cooperation with the adjacent connecting holes 46. One end of each connecting column 43 close to the center of the winding cylinder 1 is fixedly connected with a pressing block 44. The cams 42 are all rotatably connected to the left and right ends inside the winding cylinder 1. The cams 42 on the same side are all installed in cooperation with the adjacent pressing blocks 44. The fixing mechanism 4 further includes a second spring 45. The second springs 45 are all fixedly connected to the upper surfaces of the pressing blocks 44 and the adjacent ends of the inner wall of the winding cylinder 1. The second springs 45 are all sleeved on the outer surfaces of the connecting columns 43. The fixing mechanism 4 further includes a knob 41 and a rotating shaft 48. The rotating shaft 48 is rotatably connected between the left and right inner walls of the winding cylinder 1. The left and right ends of the rotating shaft 48 are both fixedly connected to the inside of the adjacent cams 42. The left end of the rotating shaft 48 is fixedly connected with a knob 41. It further includes a positioning mechanism 3. The positioning mechanism 3 includes a first sliding hole 31, a positioning column 32, and a positioning hole 34. The first sliding holes 31 are respectively opened at the upper and lower ends of the right side surface of the knob 41. The inner walls of the first sliding holes 31 are all slidably connected with the positioning columns 32. The number of the positioning holes 34 is four. The four positioning holes 34 are all opened on the left side surface of the winding cylinder 1. The positioning holes 34 are all installed in cooperation with the laterally adjacent positioning columns 32. Chamfer structures are provided at the right ends of the positioning columns 32 and the edges of the positioning holes 34. The positioning mechanism 3 further includes a first spring 33. The first springs 33 are all fixedly connected to the upper and lower ends of the right side surface of the knob 41 and the adjacent ends of the left side surface of the winding cylinder 1. The first springs 33 are all sleeved on the outer surfaces of the positioning columns 32. Rotate the knob 41. The rotation of the knob 41 contacts the chamfer of the positioning hole 34 through the chamfer surface thereon, so that the positioning column 32 moves along the inner wall of the first sliding hole 31. This process will also compress the first spring 33, so that the knob 41 can rotate freely without being hindered by other parts. The rotation of the rotating shaft 48 drives the cam 42 to rotate. During the rotation of the cam 42, its eccentric end will gradually contact the pressing block 44 and apply pressure to it, so that the connecting column 43 moves along the inner wall of the second sliding hole 47 into the connecting hole 46, and at the same time compresses the second spring 45. When the eccentric end of the cam 42 completely contacts the pressing block 44, the connecting column 43 will completely insert into the connecting hole 46. This process fixes the wire blocking plate 2 on the winding cylinder 1 to ensure the stable position of the wire blocking plate 2. After the connecting column 43 completely inserts into the connecting hole 46, the positioning column 32 will move into the next positioning hole 34. In this way, the knob 41 and the cam 42 are locked in the new position. The locking of the positioning column fixes the knob 41 in the current position, and the cam 42 also remains in contact with the pressing block 44, thus ensuring the firm installation of the wire blocking plate and preventing loosening or displacement during use. When maintenance is required, rotate the knob 41 in the reverse direction to release its locked state with the positioning column 32.This rotation causes the positioning post 32 to disengage from its current positioning hole 34. The reverse rotation of the knob 41 causes the rotation direction of the rotating shaft 48 to change, which in turn causes the eccentric end of the cam 42 to gradually move away from the extrusion block 44. The release of this pressure causes the connecting post 43 to withdraw from the connecting hole 46 under the action of the second spring 45. As the connecting post 43 withdraws from the connecting hole 46, the wire blocking plate 2 is released from fixation. At this time, the wire blocking plate 2 and the winding bobbin 1 can be easily removed. The knob 41 continues to rotate in the reverse direction until the knob 41 and the positioning post 32 return to their initial positions, thus being in a state of release from fixation, which facilitates other adjustments or maintenance.

[0026] The working principle of a skeleton for an assembled high-frequency transformer provided by the present utility model is as follows: First, a copper wire or an aluminum wire is wound around the winding bobbin 1. Then, the connection ports on the wire blocking plate 2 are installed at the left and right ends of the winding bobbin 1. Then, the knob 41 is rotated. The rotation of the knob 41 contacts the chamfer of the positioning hole 34 through the chamfered surface thereon, causing the positioning post 32 to move along the inner wall of the first sliding hole 31. This process also compresses the first spring 33, enabling the knob 41 to rotate freely without being obstructed by other parts. The rotation of the rotating shaft 48 drives the cam 42 to rotate. During the rotation of the cam 42, its eccentric end gradually contacts the extrusion block 44 and applies pressure thereto, causing the connecting post 43 to move along the inner wall of the second sliding hole 47 into the connecting hole 46 while compressing the second spring 45. When the eccentric end of the cam 42 fully contacts the extrusion block 44, the connecting post 43 completely inserts into the connecting hole 46. This process fixes the wire blocking plate 2 on the winding bobbin 1, ensuring the stable position of the wire blocking plate 2. After the connecting post 43 completely inserts into the connecting hole 46, the positioning post 32 moves to the next positioning hole 34, so that the knob 41 and the cam 42 are locked in a new position. The locking of the positioning post fixes the knob 41 in its current position, and the cam 42 also remains in contact with the extrusion block 44, thus ensuring the firm installation of the wire blocking plate and preventing loosening or displacement during use. After assembly, the copper wire is connected to the pin 6, ensuring that all electrical connections are correct, and checking the stability and functionality of the overall structure to confirm that the performance of the transformer meets the requirements. When maintenance is required, the knob 41 is rotated in the reverse direction to release its locking state with the positioning post 32. This rotation causes the positioning post 32 to disengage from its current positioning hole 34. The reverse rotation of the knob 41 causes the rotation direction of the rotating shaft 48 to change, which in turn causes the eccentric end of the cam 42 to gradually move away from the extrusion block 44. The release of this pressure causes the connecting post 43 to withdraw from the connecting hole 46 under the action of the second spring 45. As the connecting post 43 withdraws from the connecting hole 46, the wire blocking plate 2 is released from fixation. At this time, the wire blocking plate 2 and the winding bobbin 1 can be easily removed. The knob 41 continues to rotate in the reverse direction until the knob 41 and the positioning post 32 return to their initial positions, thus being in a state of release from fixation, which facilitates other adjustments or maintenance.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included within the patent protection scope of the present utility model.
