[0002] Miniature transformers are small and lightweight transformers commonly used in electronic devices and circuits for voltage conversion, electrical isolation, and signal transmission. Compared to traditional high-power transformers, miniature transformers are mainly used in low-power applications, with common power ranges from a few milliwatts to tens of watts. They are widely used in consumer electronics, communication equipment, medical instruments, industrial control, automotive electronics, and other fields.

[0003] Patent CN209045320U discloses a practical miniature transformer, including a main housing with an iron core inside. A primary coil and a secondary coil are wound around the iron core. Several junction boxes are located at the lower end of the main housing. Input terminals are located in the junction box on the left, and output terminals are located in the junction box on the right. The input terminals are connected to the primary coil. This patent proposes to improve the moisture resistance of the main housing by placing alumina powder in a placement tank. However, in actual use, the alumina powder absorbs moisture from the main housing, causing it to clump inside the placement tank, making it difficult to clean. Furthermore, the heat generated during the operation of the miniature transformer causes the moisture absorbed by the alumina powder to evaporate easily, making the internal environment of the miniature transformer humid and hot, which can negatively impact its operation.

[0004] Therefore, a miniature transformer with moisture-proof function is needed. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents, where alumina powder absorbs moisture from the main housing and clumps inside the placement tank, making it difficult to clean, and where the heat generated during the operation of the micro transformer causes the moisture absorbed by the alumina powder to evaporate easily, making the internal environment of the micro transformer humid and hot, thus affecting the use of the micro transformer, this utility model provides a micro transformer with moisture-proof function.

[0006] The technical implementation scheme of this utility model is as follows: a miniature transformer with moisture-proof function includes a miniature transformer body, a protective shell, a filter screen and rubber rings. The protective shell is slidably arranged on the miniature transformer body. Heat dissipation vents are opened on both the left and right sides of the protective shell. A filter screen is embedded in the heat dissipation vents. Multiple rubber rings are arranged on both the front and rear sides of the protective shell. It also includes a storage frame and a sealing plug. The storage frame is slidably arranged on both the left and right sides of the protective shell. The storage frame is used to place dehumidifier. A sealing plug is inserted into the storage frame.

[0007] Furthermore, it also includes a mounting block, heat sink, mounting shell, and fan. The mounting block is fixedly connected inside the protective shell, and multiple heat sinks are installed inside the mounting block. The mounting shell is fixedly connected to the top of the mounting block, and two fans are installed inside the mounting shell.

[0008] Furthermore, it also includes a fixing block, a locking block, a guide rod, an elastic element, a rotating shaft, and a limiting block. Fixing blocks are installed on both the left and right sides of the micro transformer body. Two guide rods are fixedly connected to the fixing blocks. The two guide rods are slidably mounted with locking blocks. Elastic elements are sleeved on the guide rods. The two ends of the elastic elements are connected to the fixing blocks and the locking blocks, respectively. Two rotating shafts are fixedly connected to both the left and right sides of the micro transformer body. Limiting blocks are rotatably mounted on the rotating shafts. The limiting blocks are in contact with the locking blocks.

[0009] Furthermore, it also includes a dustproof net, with a dustproof net installed on the top of the mounting housing.

[0010] Furthermore, it also includes mounting brackets, with two mounting brackets slidingly mounted on the miniature transformer body.

[0011] Furthermore, it also includes two mounting holes on both the left and right sides of the miniature transformer body.

[0012] Compared with the prior art, this utility model provides a miniature transformer with moisture-proof function, which has the following beneficial effects: 1. The desiccant inside the storage frame absorbs the moisture inside the protective shell, thereby achieving the purpose of moisture prevention, protecting the electronic components inside the miniature transformer body, and avoiding the miniature transformer being easily affected during use; and when the desiccant reaches saturation, the storage frame can be pulled outward to pull it out from inside the protective shell, and then the sealing plug can be pulled out to open the storage frame, thereby facilitating the cleaning and replacement of the desiccant.

[0013] 2. The heat sink conducts heat out of the micro transformer, and the fan accelerates air circulation, thereby expelling this heat to the outside, achieving efficient heat dissipation and preventing excessive temperature from affecting the normal operation of the micro transformer.

[0014] 3. By releasing the locking block, the elastic element returns to its original shape, causing the locking block to move inward and engage with the protective shell, thereby limiting the protective shell and preventing it from loosening. Attached Figure Description

Detailed Implementation

[0021] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example 1: A miniature transformer with moisture-proof function, please refer to... Figures 1-4 The device includes a miniature transformer body 1, a protective shell 2, a filter screen 4, and rubber rings 5. The protective shell 2 is slidably mounted on the miniature transformer body 1. Heat dissipation vents 3 are provided on both the left and right sides of the protective shell 2. Filter screens 4 are embedded in the heat dissipation vents 3 to prevent dust from entering while allowing air circulation. Several rubber rings 5 ​​are provided on both the front and rear sides of the protective shell 2. Storage frames 10 are slidably mounted on both the left and right sides of the protective shell 2. The storage frames 10 are used to hold dehumidifiers and are sealed with sealing plugs 11 to prevent moisture from entering the storage frames 10 and maintain a dry environment inside the storage frames 10. Two fixing brackets 19 are slidably mounted on the miniature transformer body 1 to limit the connection of power cords and signal lines, preventing loosening. Two mounting holes 20 are provided on both the left and right sides of the miniature transformer body 1 for easy installation and fixing.

[0023] When the miniature transformer is needed, first place the miniature transformer body 1 in a suitable position on the electronic device, then insert the bolts into the mounting holes 20 and tighten them with a tool to fix the miniature transformer body 1 to the base plate of the electronic device. Next, pick up the protective shell 2 and put it on the miniature transformer body 1 to wrap it. The protective shell 2 not only provides physical protection but also plays a certain role in electromagnetic shielding. Then, thread the power cord and signal wires through the rubber ring 5 and connect them correctly to the corresponding terminals of the miniature transformer. Afterward, pull the storage frame 10 outward to pull it out from inside the protective shell 2, and then remove the sealing plug 11. To open the storage box 10, place the desiccant inside and then reinsert the sealing plug 11. Close the storage box 10 and push it inwards to push it back into the protective shell 2. When using the miniature transformer, the desiccant inside the storage box 10 absorbs moisture from inside the protective shell 2, thus achieving moisture protection and protecting the electronic components inside the miniature transformer body 1, preventing the miniature transformer from being easily affected during use. When the desiccant reaches saturation, pull the storage box 10 outwards to pull it out of the protective shell 2, then pull out the sealing plug 11 to open the storage box 10, making it easy to clean and replace the desiccant.

[0024] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 3 The protective shell 2 is fixedly connected to the mounting block 6. The mounting block 6 is equipped with several heat sinks 7 to increase the heat dissipation area. The top of the mounting block 6 is fixedly connected to the mounting shell 8. The mounting shell 8 is equipped with two electric fans 9. The top of the mounting shell 8 is equipped with a dustproof net 18 to prevent dust and other foreign objects from entering the electric fans 9 and affecting the normal use of the electric fans 9.

[0025] When the miniature transformer operates for a long time, it generates heat. The heat sink 7 conducts the heat out of the miniature transformer. Then, the fan 9 is turned on. When the fan 9 is running, it accelerates the air circulation, thereby expelling this heat to the outside, thus achieving the purpose of efficient heat dissipation and avoiding excessive temperature from affecting the normal operation of the miniature transformer.

[0026] Please see Figure 1 , Figure 4 and Figure 5 The micro transformer body 1 has fixed blocks 12 installed on both the left and right sides. Two guide rods 14 are fixedly connected to the fixed blocks 12. The two guide rods 14 are slidably provided with a locking block 13. An elastic element 15 is sleeved on the guide rods 14. The two ends of the elastic element 15 are respectively connected to the fixed blocks 12 and the locking blocks 13. Two rotating shafts 16 are fixedly connected to both the left and right sides of the micro transformer body 1. A limit block 17 is rotatably provided on the rotating shaft 16. The limit block 17 is in contact with the locking block 13.

[0027] When the protective shell 2 is fitted onto the micro transformer body 1, first rotate the limiting block 17 outward, then pull the locking block 13 outward, compressing the elastic element 15. Then, fit the protective shell 2 onto the micro transformer body 1. When the protective shell 2 contacts the micro transformer body 1, release the locking block 13. The elastic element 15 returns to its original state, causing the locking block 13 to move inward and engage with the protective shell 2, thereby limiting the protective shell 2 and preventing it from loosening. Finally, rotate the limiting block 17 inward so that it contacts the locking block 13 and limits its movement.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
