Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a high-frequency transformer that is easy to install and fix. Background Technology

[0002] High-frequency transformers are core electronic components in switching power supplies, inverters, and various high-frequency power equipment. Their performance and operational stability are directly related to the reliability of the entire system. Under high-frequency operating conditions, transformers generate a large amount of heat due to core losses and winding copper losses. If the heat cannot be dissipated in time, the transformer temperature will be too high, which will affect the working efficiency and service life. Therefore, in structural design, transformers are usually equipped with a mounting shell with ventilation openings to promote air circulation and heat dissipation.

[0003] However, while ventilation openings facilitate heat dissipation, they also provide a channel for dust and suspended particles from the external environment to enter the equipment. Once this dust adheres to the surface of the transformer body or the windings, it will severely hinder the conduction and dissipation of heat, causing localized overheating. In addition, if conductive dust is present in the environment, it can cause short circuits between windings, posing a serious safety hazard to the equipment. Therefore, existing technologies usually install dust filters at the ventilation openings. However, after long-term use, the dust filters will become clogged with dust, affecting the ventilation effect and requiring regular cleaning. The dust filters in existing structures are mostly fixed with screws or integrated clips, which are cumbersome to disassemble and require the use of special tools, causing many inconveniences to on-site maintenance work and reducing maintenance efficiency.

[0004] Therefore, this utility model proposes a high-frequency transformer that is easy to install and fix, in order to overcome the shortcomings of the prior art. Summary of the Invention

Figure 5 and Figure 6The dustproof mechanism 3 includes an air inlet 301 on the mounting shell 4, an mounting groove 302 inside the air inlet 301, a dustproof net 303 slidably connected inside the mounting groove 302, a connecting plate 304 connected to the dustproof net 303, a handle 305 fixedly connected to the front side of the connecting plate 304, the dustproof mechanism 3 also includes a fixing block 306, a push plate 310 and a limiting plate 311, the limiting plate 311 is set at the bottom of the push plate 310, a cavity 307 is provided inside the fixing block 306, a vertical rod 309 is connected to the push plate 310 and slidably passes through the fixing block 306 and extends into the cavity 307, a spring 308 is provided inside the cavity 307 for resetting the push plate 310.

[0024] Please refer to Figure 3 and Figure 4 The fixing mechanism 2 includes a rotating plate 204 rotatably connected to the mounting shell 4. Screws 209 are slidably connected to the rotating plate 204. A sliding groove 205 is formed inside the rotating plate 204, and a rod 207 is slidably disposed within the sliding groove 205. The rod 207 is engaged with a spring 206 for driving the rod 207 to reset. The rod 207 is also fixedly connected to a lever 208 located outside the rotating plate 204. The mounting shell 4, which engages with the rotating plate 204, has a positioning hole 210 and a positioning hole 211. By moving the lever 208, the rod 207 can be moved within the sliding groove 205. 05 Slides and compresses the spring 206, causing the end of the insertion rod 207 to exit from the positioning hole 210 or the positioning hole 211. At this time, the rotating plate 204 can rotate relative to the mounting shell 4. When the rotating plate 204 rotates to a predetermined angle, the lever 208 is released. Under the elastic force of the spring 206, the insertion rod 207 is pushed out and inserted into the corresponding positioning hole 210 or the positioning hole 211, thereby locking the angle of the rotating plate 204. This locking structure, in which the insertion rod 207 selectively matches the positioning hole, ensures that the mounting shell 4 can stably switch and be fixed in either horizontal or vertical mounting positions.

[0025] Please refer to Figure 5 and Figure 6The dustproof mechanism 3 has an installation groove 302 inside the air inlet 301. The dustproof net 303 is installed in the installation groove 302 by sliding connection. One end of the dustproof net 303 is fixedly connected to a connecting plate 304. The front side of the connecting plate 304 is fixedly connected to a handle 305 for easy pulling. The dustproof mechanism 3 also includes a fixing block 306, a push plate 310 and a limiting plate 311. The fixing block 306 is fixed to the mounting shell 4 and has an internal cavity 307.

At the bottom of 10, the upright 309 is connected to the push plate 310 and slidably passes through the fixing block 306 with its end extending into the cavity 307. The cavity 307 is also provided with a second spring 308 for resetting the push plate 310. In its natural state, the second spring 308 pushes the push plate 310 out, causing the limiting plate 311 to abut against the front of the connecting plate 304, thereby limiting and locking the dustproof net 303. This structure, which releases the lock by pressing the push plate to move the limiting plate, realizes the quick disassembly and assembly of the dustproof net 303, greatly facilitating cleaning and maintenance.

[0026] As a preferred embodiment, in order to achieve a stable fixation of the transformer body 1 within the mounting housing 4, refer to Figure 2 and Figure 4 The bottom of the transformer body 1 is fixedly connected with a positioning bolt 201. The bottom of the mounting shell 4 is provided with a mounting groove 202 for the positioning bolt 201 to pass through. After the positioning bolt 201 passes through the mounting groove 202, it is locked from the outside of the mounting shell 4 by a nut 203. The transformer body 1 is firmly fixed to the bottom of the mounting shell 4 by the cooperation of the bolt and the nut 203.

[0027] As another preferred embodiment, in order to provide effective protection for the transformer body 1 inside the mounting housing 4, refer to Figure 1 and Figure 2 The opening end of the mounting shell 4 is covered by a cover plate 5. The cover plate 5 and the mounting shell 4 are respectively provided with a hook 6 and a latch 7 that cooperate with each other. By fastening the hook 6 onto the latch 7, the cover plate 5 and the mounting shell 4 can be quickly locked and closed.

[0028] As a preferred embodiment of the fixing mechanism 2, in order to facilitate the operation of the insertion rod 207 to unlock the rotating plate 204 and to accommodate the fixing point positions of the screws 209 on different mounting surfaces, refer to Figure 3 The fixing mechanism 2 also includes a lever 208 fixedly connected to the insertion rod 207. The lever 208 is located outside the rotating plate 204. The user can directly move the lever 208 to drive the insertion rod 207 to move within the sliding groove 205. Furthermore, the elongated through hole on the rotating plate 204 allows the screw 209 to form a sliding connection with the rotating plate 204, allowing the screw 209 to adjust its position within a certain range.

[0029] As a preferred embodiment of the dustproof mechanism 3, in order to ensure the smooth and stable pulling process of the dustproof net 303, and to facilitate the operator in pulling the dustproof net 303 and to achieve reliable limiting, refer to Figure 5 The air inlet 301 has two mounting grooves 302 formed by guide rails on both sides. The two side frames of the dustproof net 303 are slidably connected to the inside of the mounting grooves 302. The front end of the dustproof net 303 is fixedly connected to a connecting plate 304. A handle 305 for hand gripping is fixedly connected to the connecting plate 304. In the locked state, the front end of the limiting plate 311 abuts against the rear side of the connecting plate 304.

[0030] As a further optimization of the unlocking structure of the dustproof mechanism 3, in order to construct a compact and resiliently elastic quick-unlocking device, refer to Figure 5 and Figure 6 The dustproof mechanism 3 also includes a fixing block 306 fixed to the mounting shell 4. The interior of the fixing block 306 forms a hollow cavity 307. The limiting plate 311 is disposed at the bottom of the push plate 310. The lower end of the upright rod 309 is connected to the push plate 310 and can slide upward through the fixing block 306. The upper end of the upright rod 309 extends into the cavity 307. Inside the cavity 307, a second spring 308 is sleeved on the upright rod 309 to reset the push plate 310. The two ends of the second spring 308 abut against the shoulder of the upright rod 309 and the inner top wall of the cavity 307, respectively.

[0031] Working principle: When assembling the entire device, the transformer body 1 is first placed inside the mounting shell 4, so that the multiple positioning bolts 201 at the bottom of the transformer body 1 pass through the mounting grooves 202 opened at the bottom of the mounting shell 4. Then, the nuts 203 are screwed into the positioning bolts 201 from the outside of the mounting shell 4, thereby firmly fixing the transformer body 1 inside the mounting shell 4. Then, the cover plate 5 is covered over the opening end of the mounting shell 4, and the multiple hooks 6 on the cover plate 5 are engaged with the multiple latches 7 on the mounting shell 4 to complete the encapsulation of the entire device and provide comprehensive mechanical protection for the transformer body 1 inside. During on-site installation, the fixing mechanism 2 of this utility model provides great convenience. The user first determines the installation direction according to the nature of the mounting surface. If it is necessary to fix the device on a horizontal surface, the operator needs to move the lever 208 set on the outside of the rotating plate 204. Since the lever 208 is fixedly connected to the insertion rod 207, moving the lever 208 will cause the insertion rod 207 to slide in the sliding groove 205 inside the rotating plate 204 and compress the spring 206 in the sliding groove 205, so that the end of the insertion rod 207 is retracted from the original locked position. At this time, the rotating plate 204 can rotate freely relative to the mounting shell 4. Rotate the rotating plate 204 to a horizontal position so that the insertion rod 207 is aligned with the positioning hole opened on the mounting shell 4. 1. Release the lever 208. Under the restoring force generated when the elastic potential energy stored in the spring 206 is released, the insertion rod 207 will quickly and reliably insert into the positioning hole 210, thereby firmly locking the rotating plate 204 in the horizontal installation position. If it is necessary to fix the device to a vertical wall, repeat the above operation. Simply rotate the rotating plate 204 to the vertical position, align the insertion rod 207 and insert it into the positioning hole 211 to lock it. After the position is locked, the user can use the screw 209 that is slidably connected on the rotating plate 204 to firmly fix the entire mounting shell 4 to the target mounting surface. This rotatable and bidirectional locking structure completely solves the problem of the single installation method of traditional transformers. During long-term operation of the device, the heat generated by the transformer body 1 needs to be dissipated in a timely manner, while preventing external dust from entering. The dustproof mechanism 3 of this utility model can solve these two problems in a coordinated manner. During operation, external cold air enters through the air inlet 301 on the mounting shell 4, forming convection inside and carrying away the heat generated by the transformer body 1 during operation. The dustproof net 303, which is slidably connected in the mounting groove 302 inside the air inlet 301, can effectively filter and block dust in the air, protecting the cleanliness of the internal components. When the dustproof net 303 needs to be cleaned due to excessive dust accumulation, the quick-disassembly structure shows a great advantage. The operator only needs to press the push plate 310 inward by hand, and the push plate 310 will drive the upright rod 309 connected to the push plate 310 to slide upward within the fixing block 306, and Spring 308, which enters the cavity 307 and compresses the interior, causes the limiting plate 311, which is integrated with the push plate 310, to rise upwards, thus disengaging from the contact limit of the connecting plate 304 at the front end of the dustproof net 303. At this time, the lock on the dustproof net 303 is released, and the operator can directly grasp the handle 305 on the connecting plate 304 to easily pull the dustproof net 303 out of the mounting slot 302 for cleaning or replacement. After cleaning, the dustproof net 303 is pushed back to its original position along the mounting slot 302, and then the push plate 310 is released. Under the elastic force of spring 308, the push plate 310, the upright 309, and the limiting plate 311 automatically reset, causing the limiting plate 311 to re-lock the connecting plate 304, thus completing the re-locking of the dustproof net 303. The whole process requires no tools and is extremely simple and quick to operate.
