Description

Technical Field

[0001] The present invention relates to the field of high-frequency transformers, and in particular to a high-frequency transformer based on a quick-plug winding connection structure. Background Art

[0002] In the field of power electronics, switching power supplies are widely used in various electronic devices to provide the necessary power conversion for their stable operation. High-frequency transformers are the core elements of switching power supplies. Currently, most high-frequency transformers adopt a skeleton integrated design to streamline the structure and improve production efficiency. Under this integrated architecture, the magnetic core is usually inserted into the slot and fixed to the skeleton with tape or glue.

[0003] In actual use, fixing the magnetic core by dispensing glue is not conducive to later disassembly and maintenance. When the magnetic core is fixed with tape, the tape is easily fatigued and loosened because high-frequency transformers are often subjected to unavoidable vibration shocks due to the influence of the external environment (such as strong vibration caused by the operation of industrial equipment and collisions caused by daily use of consumer electronic products). This causes the two magnets in the magnetic core of the high-frequency transformer to shift slightly. This displacement will cause the air gap between the two magnets in the magnetic core to change (the air gap refers to the air gap deliberately left between the two E-shaped magnets in the magnetic core. Its function is to prevent core saturation, adjust inductance, enhance energy storage capacity, and improve heat dissipation performance by increasing magnetic resistance, so that the magnetic core and related electromagnetic components can work more stably and effectively). This will cause fluctuations in magnetic circuit characteristics, resulting in unstable magnetic resistance and inductance, which in turn leads to increased output voltage ripple and poor stability. It may even cause core saturation, resulting in a surge in excitation current, heating of the winding, reduced efficiency, and the risk of burnout. It will also cause output waveform distortion and affect system reliability. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the prior art, the present invention provides an injection mold equipped with an injection molding structure that automatically optimizes the plastic recycling ratio. It can effectively solve the problem in the prior art that high-frequency transformers used in switching power supplies mostly adopt a skeleton-integrated design. In actual use, they are affected by the vibration of industrial equipment, collision of electronic products, etc., and traditional gluing or tape fixation is insufficient to constrain the magnetic core, which will cause the magnet in the magnetic core to shift, thereby changing the air gap between the two magnets in the magnetic core, and then causing magnetic circuit fluctuations, causing power supply filtering and energy storage to malfunction, and may also cause core saturation and winding burning, affecting system reliability.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A high-frequency transformer based on a quick-plug winding connection structure, comprising:

[0007] The skeleton adopts a modular design and consists of three parts: a winding drum, a terminal seat and a connecting seat. The two ends of the winding drum are fixedly connected to the sockets. The terminal seat and the connecting seat are both provided with sockets and are symmetrically plugged into the winding drum through the sockets. The terminal seat and the connecting seat are also locked and connected to the winding drum through a tightening mechanism.

[0008] Pins, wherein the pins are arranged in a straight line in front and back as a group, two groups are fixedly connected symmetrically up and down at the left end of the terminal seat, and each pin is connected to a winding mechanism that assists in connecting the coil to the pin.

[0009] The magnetic core includes an E-shaped magnet, and slots are provided on the terminal seat and the connecting seat. The terminal seat, the connecting seat and the winding drum are symmetrically connected with the E-shaped magnet, and the E-shaped magnet is provided with a locking mechanism that cooperates with the tightening mechanism.

[0010] Among them, the winding mechanism includes a rotating drum, which is rotatably mounted on the pin and its right end is connected to the terminal seat through a lifting assembly. The left end of the rotating drum is fixedly connected to a lead seat that assists in winding the coil lead wire around the pin.

[0011] Furthermore, a wire hole is formed through the lead base, and the width of the wire hole gradually increases from left to right. A clamping component is also fixedly connected to the lead base to keep the coil lead wire taut during the winding process.

[0012] Furthermore, the lifting assembly includes a screw, and a mounting groove corresponding to the rotating cylinder is opened on the terminal seat. The screw is located in the mounting groove and is fixedly connected to the right end of the rotating cylinder. The screw is rotatably sleeved on the pin, and the screw and the pin can rotate relative to each other. The screw is connected to the terminal seat through a thread, and a rotating ring is fixedly sleeved on the screw, and a slot hole matching the rotating ring is opened on the side wall of the terminal seat cavity.

[0013] Furthermore, the clamping assembly includes a stop block, which is arranged in the wire hole. The right end of the stop block is fixedly connected to a short rod. The short rod passes through the lead seat and the rotating drum and is slidingly connected to both of them. The short rod and the rotating drum are connected by a pressure spring.

[0014] Furthermore, the clamping mechanism connected to the terminal seat includes a locking cavity, and there are two locking cavities fixed and connected symmetrically at the upper and lower left end of the winding drum. A slot matching the locking cavity is opened on the terminal seat, and multiple locking plates are evenly rotated and connected inside the locking cavity and close to the E-shaped magnet. A convex strip matching the locking plate is fixedly connected to the E-shaped magnet, and a locking assembly is connected inside the locking cavity and away from the E-shaped magnet.

[0015] Furthermore, the lock assembly includes a pressure block, which is slidably connected to the locking cavity up and down, and a spring seat is fixedly connected to the end of the pressure block away from the lock plate. The movable section of the spring seat is slidably connected to the locking cavity, and a stepped groove corresponding to the spring seat is slidably opened on the terminal seat, and a cylindrical seat is slidably connected in the stepped groove. The installation method of the tightening mechanism connected to the connecting seat is the same as the tightening mechanism connected to the terminal seat.

[0016] Furthermore, the locking mechanism includes a folding plate, two of which are symmetrically arranged on the left and right sides, and trapezoidal grooves are symmetrically opened on the edges of the left end faces of the terminal seat and the connecting seat. The folding plate is inserted into the corresponding trapezoidal groove, and the two horizontal sections of the folding plate that are symmetrical on the upper and lower sides are connected with interlocking components that cooperate with the columnar seat.

[0017] Furthermore, the interlocking assembly includes a wedge block No. 1, which is fixedly connected to the end of the cylindrical seat away from the spring seat, and a wedge block No. 2 that cooperates with the wedge block No. 1 is fixedly connected to the folding plate, and the upper end of the wedge block No. 2 is rotatably connected to a bolt, and the bolt and the folding plate are connected by a threaded connection.

[0018] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0019] When the E-shaped magnet is inserted into the slot and the hollow space of the winding drum in this embodiment, as the longitudinal section in the middle of the E-shaped magnet is completely inserted into the hollow space of the winding drum, the locking plate abuts against the left end of the corresponding convex strip under the action of the pressure block and the spring seat. Subsequently, when the upper and lower horizontal sections of the folding plate are aligned and inserted into the corresponding trapezoidal slots, the inclined surface of the No. 2 wedge block will contact the inclined surface of the No. 1 wedge block and exert pressure on it, thereby driving the No. 1 wedge block on the left and the corresponding column block to move toward the direction of the left spring seat, making way for the No. 2 wedge block on the left. In this process, the left spring seat will be compressed. When the No. 2 wedge block on the left moves to the left When the left side wedge block is to the right side, the left spring seat is reset, driving the left cylindrical seat and the left No. 1 wedge block to reset. Here, the end of the left No. 1 wedge block away from the left spring seat will be blocked by the folding plate and will not be completely reset. Therefore, it will continue to exert a certain pressure on the left cylindrical block, the pressure block and the spring seat, driving the left lock plate to further deflect to the right, thereby further pressing against the convex strip to ensure the locking effect. In this process, the adaptive expansion and contraction of the spring seat will make the deflection angle of the lock plate adaptively adjusted, and will also keep the air gap between the middle longitudinal sections of the two E-shaped magnets unchanged, thereby avoiding the influence of external vibration on the performance of the high-frequency transformer.

DETAILED DESCRIPTION

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The present invention will be further described below with reference to the embodiments. Example

[0031] See Figure 1-Figure 7 , a high-frequency transformer based on a quick-plug winding connection structure, comprising:

[0032] Skeleton 1, the skeleton 1 adopts a modular design and consists of three parts: a winding drum 11, a terminal seat 12 and a connecting seat 13. The winding drum 11 adopts a hollow design. Unlike the conventional winding drum 11, two ends thereof are fixedly connected with two sockets 121 for plugging into the terminal seat 12 and the connecting seat 13. Both the terminal seat 12 and the connecting seat 13 are provided with sockets 122 corresponding to the sockets 121. The two are symmetrically plugged into the left and right ends of the winding drum 11 and are connected to the winding drum 11 through a tightening mechanism 14.

[0033] Pins 2, the pins 2 are arranged in a straight line in front and back as a group, and two groups are fixedly connected symmetrically at the left end of the terminal block 12. The pins 2 and the terminal block 12 are jointly connected with a winding mechanism 21, and the winding mechanism 21 is used to connect the pins 2 and the lead wires of the coil.

[0034] The magnetic core 3 includes an E-shaped magnet 31, two of which are symmetrically arranged on the left and right. A slot 32 that cooperates with the E-shaped magnet 31 is provided on the terminal seat 12 and the connecting seat 13. During assembly, the front and rear longitudinal sections of the E-shaped magnet 31 are inserted into the corresponding slots 32, and the longitudinal section near the middle is inserted into the interior near the winding drum 11. The E-shaped magnet 31 is provided with a locking mechanism 33 that cooperates with the tightening mechanism 14.

[0035] Among them, the winding mechanism 21 includes a rotating drum 211, which is rotatably mounted on the pin 2 and its right end is connected to the terminal seat 12 through a lifting assembly 212. The left end of the rotating drum 211 is fixedly connected to a lead seat 213, and a wire hole 214 is opened on the lead seat 213. The width of the wire hole 214 gradually increases from left to right to facilitate the insertion of the coil lead wire. The lead seat 213 is also fixedly connected to a clamping assembly 215 that keeps the coil lead wire taut during the winding process.

[0036] During the specific implementation, the enameled wire and the insulating tape are wound on the bobbin 11 in layers according to the processing requirements through an external winding machine to form a coil, and the lead wire of appropriate length is reserved. Then, the terminal seat 12 and the connecting seat 13 are respectively inserted into the left and right ends of the bobbin 11, and the two E-shaped magnets 31 are symmetrically inserted into the slots 32. Then, each lead wire is passed through the corresponding wire hole 214 and manually pulled to tighten it. Then, the lifting assembly 212 is operated to rotate the drum 211, driving the lead seat 213 to synchronously revolve around the pin 2, so that The lead wire is wound around the corresponding pin 2. While the drum 211 rotates, it will also move to the right relative to the pin 2 driven by the lifting component 212, thereby ensuring that the lead wire is evenly wound from left to right on the pin 2. At the same time, during the winding process, the clamping component 215 cooperates with the lead holder 213 to apply a certain resistance force to the lead wire, so that the lead wire always remains taut during the winding process, ensuring the normal progress of the winding process. Compared with conventional soldering and crimping methods, this wiring method has higher connection strength and will not damage the pin 2 during disassembly.

[0037] The lifting assembly 212 includes a screw 2121, and a mounting groove corresponding to the rotating cylinder 211 is opened on the terminal seat 12. The screw 2121 is located in the mounting groove and is fixedly connected to the right end of the rotating cylinder 211. The screw 2121 is rotatably sleeved on the pin 2, and the screw 2121 and the pin 2 can rotate relative to each other. The screw 2121 is connected to the terminal seat 12 by a thread, and a rotating ring 2122 is fixedly sleeved on the screw 2121. The side wall of the cavity of the terminal seat 12 is provided with a slot hole matching the rotating ring 2122.

[0038] The clamping assembly 215 includes a stop block 2151, which is arranged in the wire hole 214. The right end of the stop block 2151 is fixedly connected to a short rod 2152. The short rod 2152 passes through the lead seat 213 and the rotating drum 211 and is slidably connected to both. The short rod 2152 and the rotating drum 211 are connected by a pressure spring 2153.

[0039] The clamping mechanism 14 connected to the terminal seat 12 includes a locking cavity 141, and two locking cavities 141 are fixed and connected symmetrically at the upper and lower ends of the left end of the winding drum 11. A slot that matches the locking cavity 141 is opened on the terminal seat 12, and a plurality of locking plates 142 are evenly rotated and connected inside the locking cavity 141 and close to the E-shaped magnet 31. A convex strip 143 that matches the locking plate 142 is fixedly connected to the E-shaped magnet 31, and a locking assembly 144 is connected inside the locking cavity 141 and away from the E-shaped magnet 31.

[0040] The lock assembly 144 includes a pressure block 1441, which is slidably connected to the locking cavity 141 up and down. The pressure block 1441 is fixedly connected to the end away from the lock plate 142 with a spring seat 1442. The movable section of the spring seat 1442 is slidably connected to the locking cavity 141. A stepped groove corresponding to the spring seat 1442 is slidably opened on the terminal seat 12, and a cylindrical seat 1443 is slidably connected in the stepped groove. The installation method of the tightening mechanism 14 connected to the connecting seat 13 is the same as the tightening mechanism 14 connected to the terminal seat 12.

[0041] The locking mechanism 33 includes a folding plate 331, and two folding plates 331 are symmetrically arranged on the left and right. Trapezoidal grooves 332 are symmetrically opened on the edges of the left end faces of the terminal seat 12 and the connecting seat 13. The folding plates 331 are inserted into the corresponding trapezoidal grooves 332. The two horizontal sections of the folding plates 331 that are symmetrical on the upper and lower sides are connected with interlocking components 333 that cooperate with the columnar seat 1443.

[0042] The interlocking assembly 333 includes a wedge block No. 1 3331, which is fixedly connected to the end of the cylindrical seat 1443 away from the spring seat 1442. A wedge block No. 2 3332 that cooperates with the wedge block No. 1 3331 is fixedly connected to the folding plate 331. The upper end of the wedge block No. 2 3332 is rotatably connected to a bolt, and the bolt and the folding plate 331 are connected by a threaded connection.

[0043] In specific implementation, the assembly of the high-frequency transformer includes the following steps:

[0044] 1. Winding: Fix one end of the enameled wire at the starting position of the winding drum 11 to ensure that the starting end of the enameled wire will not loosen, start the external winding machine, and wind the enameled wire evenly and tightly on the winding drum 11 according to the number of turns and winding direction required by the design. During the winding process, pay attention to keeping the tension of the enameled wire moderate to avoid loosening the coil due to being too loose or damaging the enameled wire due to being too tight. Some high-frequency transformers need to have multiple layers of coils wound on the winding drum 11. After each layer is wound, interlayer insulation treatment is required. Generally, a layer of insulating paper is evenly spread on the wound layer of coil, and then the next layer is wound to prevent short circuit between layers.

[0045] 2. Assembly: Arrange the lead wires of each coil on the winding bobbin 11, and plug the terminal block 12 and the connecting block 13 into the left and right ends of the winding bobbin 11 respectively. The fit between the socket 121 and the socket 122 is an interference fit to ensure the stability of the connection. After the winding bobbin 11, the terminal block 12 and the connecting block 13 are connected, the E-shaped magnet 31 needs to be connected. Taking the connection of the left E-shaped magnet 31 as an example, align the three longitudinal sections of the left E-shaped magnet 31 with the corresponding slots 32 on the terminal block 12 and the hollow part of the winding bobbin 11, and plug the left E-shaped magnet 31 into them.

[0046] During the above-mentioned process of plugging in the left E-shaped magnet 31, as the middle longitudinal section of the left E-shaped magnet 31 is fed from left to right in the hollow of the winding drum 11, when the convex strip 143 thereon contacts the locking plate 142, it will drive the locking plate 142 to deflect to the right. During this period, the spring seat 1442 will adaptively expand and contract, so that the pressure block 1441 can adaptively move up and down, and then the deflection angle of the locking plate 142 will also change to avoid affecting the feeding of the left E-shaped magnet 31. After the right end face of the transverse section of the left E-shaped magnet 31 contacts the socket 121 at the left end of the winding drum 11, the left E-shaped magnet 31 is installed to the specified position. At this time, the locking plate 142 is abutted against the left end of the corresponding convex strip 143 under the action of the pressure block 1441 and the spring seat 1442.

[0047] Then align the upper and lower horizontal sections of the left folding plate 331 and insert them into the corresponding trapezoidal groove 332 on the terminal seat 12. During this process, the inclined surface of the left second wedge block 3332 will contact the inclined surface of the left first wedge block 3331 and apply pressure to it, thereby driving the left first wedge block 3331 and the corresponding columnar block to move in the direction of the left spring seat 1442 to make way for the left second wedge block 3332. During this process, the left spring seat 1442 will be compressed. When the left second wedge block 3332 moves to the right side of the left first wedge block 3331, the left spring seat 1442 will be compressed. The seat 1442 is reset, driving the left cylindrical seat 1443 and the left wedge block No. 1 3331 to reset (here, the end of the left wedge block 3331 away from the left spring seat 1442 will be blocked by the folding plate 331 and will not be completely reset, so it will exert pressure on the left cylindrical block, the pressure block 1441 and the spring seat 1442, driving the left locking plate 142 to further deflect to the right, thereby further pressing the ridge 143, and thus ensuring the stability of the E-shaped magnet 31), thereby locking the left wedge block 3332, and finally achieving the locking of the left E-shaped magnet 31.

[0048] When the lock needs to be released, the bolt is tightened with an external wrench to move the No. 2 wedge 3332 away from the cylindrical seat 1443, thereby releasing its lock on the No. 1 wedge 3331. The folding plate 331 can then be pulled out, and the lock of the left E-shaped magnet 31 is also released, and it can be pulled out from the slot 32 and the winding reel 11.

[0049] 3. Wiring: After the E-shaped magnet 31 is installed and locked, each lead wire is passed through the wire hole 214 of the corresponding lead seat 213, and manually pulled to make it tight, then the dial ring 2122 is rotated to make the rotating drum 211 and the screw 2121 rotate synchronously. The rotation of the rotating drum 211 drives the lead seat 213 to revolve around the pin 2, so that the lead wire is wound around the corresponding pin 2. When the bolt rotates, it moves to the right relative to the pin 2, thereby driving the rotating drum 211 and the lead seat 213 to move to the right synchronously, so that the lead wire can be evenly wound from left to right. At the same time, during the winding process, the block 2151 presses against the Driven by the spring 2153 and the short rod 2152, the lead wire is always kept against the left end of the wire hole 214, so that the lead wire is always kept taut against the drum 211 during the winding process, thereby ensuring that the lead wire is tightly wound. When the drum 211 feeds to the rightmost end, the short rod 2152 will contact and abut against the terminal seat 12, further tightening the wire end of the lead wire, thereby avoiding the loosening of the lead wire due to vibration. This wiring method has higher connection strength than conventional soldering and crimping methods. When disassembling, just rotate the dial ring 2122 in the opposite direction to release the abutment on the lead wire without damaging the lead wire and pin 2.

[0050] It is worth noting that the high-frequency transformer based on the quick-plug winding connection structure has the following advantages:

[0051] 1. The high-frequency transformer in this embodiment adopts a modular design. On the one hand, the production of different modules can be divided and carried out in parallel, and then quickly assembled to improve overall production efficiency. On the other hand, compared with conventional integrated high-frequency transformers, in some application scenarios where the system needs to be upgraded, maintained or expanded, this modular high-frequency transformer can easily achieve system expansion and upgrade by adding or replacing corresponding modules.

[0052] 2. In the process of locking the E-shaped magnet 31 by the folding plate 331 of this embodiment, on the one hand, the E-shaped magnet 31 is fixed from the outside by the cooperation between the second wedge block 3332 and the first wedge block 3331. On the other hand, the uppermost and lowermost horizontal sections of the folding plate 331 will also press the first wedge block 3331. Through the cylindrical seat 1443, the spring seat 1442 and the pressure block 1441, the locking plate 142 is further pressed against the convex strip 143, thereby locking the E-shaped magnet 31 from the inside, further improving the locking effect. At the same time, the adaptive expansion and contraction of the spring seat 1442 will make the deflection angle of the locking plate 142 adaptively adjusted, so that the air gap between the middle longitudinal sections of the two E-shaped magnets 31 remains unchanged, thereby avoiding the influence of external vibration on the performance of the high-frequency transformer.

[0053] 3. In this embodiment, when the dial ring 2122 is manually rotated, the rotating drum 211 and the screw 2121 will be driven to rotate synchronously. The rotation of the rotating drum 211 drives the lead holder 213 to revolve around the pin 2, thereby winding the lead wire around the corresponding pin 2. When the bolt rotates, it will move to the right relative to the pin 2, thereby driving the rotating drum 211 and the lead holder 213 to move to the right synchronously, so that the lead wire can be evenly wound around the corresponding pin 2 from left to right. At the same time, in the above process, the block 2151 always presses the lead wire against the shorter end of the lead holder 213 under the drive of the pressure spring 2153 and the short rod 2152, so that the lead wire is always kept taut during the winding process, and when the rotating drum 211 is fed to the rightmost end, the short rod 2152 will contact and press against the terminal seat 12, further tightening the lead wire, thereby avoiding the loosening of the lead wire caused by vibration. This wiring method has higher connection strength than conventional soldering and crimping methods.

[0054] 4. When the high-frequency transformer needs to be updated and maintained, if the E-shaped magnet 31 needs to be removed, it is only necessary to tighten the bolt with an external wrench to drive the No. 2 wedge 3332 to move away from the cylindrical seat 1443, thereby releasing its lock on the No. 1 wedge 3331, and then the folding plate 331 can be pulled out, and the lock of the left E-shaped magnet 31 is also released, and it can be pulled out from the slot 32 and the winding drum 11. If the lead wire needs to be removed from pin 2, it is only necessary to rotate the dial ring 2122 in the opposite direction to release the contact of the block 2151 with the lead wire. At the same time, the lead wire will automatically be untied from pin 2 as the lead seat 213 and the rotating drum 211 rotate, without damaging the lead wire and pin 2.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
