Description
Technical Field
[0001] This utility model relates to the field of switching power supply technology, specifically a switching power supply with wiring protection. Background Technology
[0002] A switching power supply is a high-efficiency power conversion device that converts input electrical energy into pulse signals by periodically switching high-frequency switching transistors (such as MOSFETs). The pulse signals are then stored and released by magnetic energy components (inductors / transformers) and filtered by capacitors before outputting stable DC power. Its core utilizes pulse width modulation (PWM) to adjust the switching duty cycle for precise voltage control. Compared to traditional linear power supplies, it offers advantages such as high conversion efficiency (up to 90% or more), small size, low heat generation, and wide voltage range adaptability. It is widely used in computers, communication equipment, industrial control systems, and consumer electronics.
[0003] In switching power supplies, terminals are usually provided at the ends for connecting power supply cables. However, in the prior art, these terminals are generally exposed, which means that the connection between the power supply cable and the terminal is exposed to the environment for a long time. This makes them very susceptible to moisture and easy to accumulate dust and dirt. Utility Model Content
[0004] The purpose of this invention is to provide a switching power supply with wiring protection to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a switching power supply with wiring protection, comprising a switching power supply body, a protective mechanism provided on the front of the switching power supply body, and a disassembly mechanism provided on the front of the protective mechanism; The protective mechanism includes a rectangular box, which is fixedly connected to the bottom of the switching power supply body. A partition is fixedly connected to the inner wall of the rectangular box. Springs are fixedly connected to the left and right sides of the partition. A rectangular block is fixedly connected to the end of the spring away from the partition. A locking block is fixedly connected to the side of the rectangular block away from the spring. A protective cover is movably connected to the front of the switching power supply body. A right-angle plate is fixedly connected to the bottom of the protective cover. A limit sleeve is fixedly connected to the bottom of the right-angle plate.
[0006] Preferably, the limiting sleeve has an opening inside, and the locking block is movably connected to the inner wall of the opening, so that the locking block can limit the limiting sleeve through the opening, thereby ensuring the stability of the protective cover during the limiting process.
[0007] Preferably, the rectangular block's shape matches the shape of the inner wall of the rectangular box, and the rectangular block is slidably connected to the inner wall of the rectangular box, allowing the rectangular block to move stably and compress the spring.
[0008] Preferably, the rectangular box has movable openings on both the left and right sides, and the card block passes through the movable openings and moves, so that the card block can move through the movable openings.
[0009] Preferably, the disassembly mechanism includes a push shaft, which is fixedly connected to the front of the rectangular block. An insert block is rotatably connected to the outer wall of the push shaft, and a limit shaft is fixedly connected to the front of the rectangular box, further improving the convenience of the disassembly process.
[0010] Preferably, the insert has a slot inside, and the size of the slot is larger than the size of the limiting shaft, so that the insert can be inserted into the outer wall of the limiting shaft.
[0011] Preferably, the push shaft passes through the insert block, and the rectangular box has a slot on its front side, through which the push shaft passes, allowing the push shaft to move through the slot.
[0012] Compared with the prior art, this utility model provides a switching power supply with wiring protection, which has the following beneficial effects: 1. This switching power supply with wiring protection, through the set protective mechanism, the spring automatically resets and pushes the locking block into the limit sleeve through-hole to form an interference fit, and together with the right angle plate tightly against the switching power supply body to form a continuous sealing surface, ensuring the stability of the protective cover while eliminating the risk of accidental reset during maintenance. In addition, the protective cover can prevent the connection parts of the power connection wire and the terminal from being exposed to the environment for a long time, avoiding the situation of being corroded by environmental moisture and easily accumulating dust and dirt.
[0013] 2. This switching power supply with wiring protection, through the set disassembly mechanism, the rotating plug drives the push shaft to move axially, and the linkage of the rectangular block compresses the spring to make the locking block accurately pull out from the limit sleeve. Then the rotating plug is locked into the limit shaft to form a mechanical self-lock, realizing the quick disassembly of the protective cover, improving the convenience of operation, completely solving the pain points of long disassembly time and limited space of traditional tools, and significantly improving maintenance efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0018] This utility model provides the following technical solution: Example 1 Combination Figures 1 to 4 A switching power supply with wiring protection includes a switching power supply body 1, a protective mechanism 3 on the front of the switching power supply body 1, and a disassembly mechanism 2 on the front of the protective mechanism 3, realizing the integrated design of quick disassembly and assembly of the protective cover and stable protection, which significantly improves the convenience of maintenance. The protective mechanism 3 includes a rectangular box 31, which is fixedly connected to the bottom of the switching power supply body 1. A partition 32 is fixedly connected to the inner wall of the rectangular box 31. Springs 33 are fixedly connected to the left and right sides of the partition 32. A rectangular block 34 is fixedly connected to the end of the spring 33 away from the partition 32. A locking block 35 is fixedly connected to the side of the rectangular block 34 away from the spring 33. A protective cover 36 is movably connected to the front of the switching power supply body 1. A right-angle plate 37 is fixedly connected to the bottom of the protective cover 36. A limit sleeve 38 is fixedly connected to the bottom of the right-angle plate 37. The spring 33 pushes the locking block into the limit sleeve 38 to ensure that the protective cover 36 is tightly locked.
[0019] Furthermore, the limiting sleeve 38 has an opening inside, and the locking block 35 is movably connected to the inner wall of the opening, so that the locking block 35 can limit the limiting sleeve 38 through the opening, thereby ensuring the stability of the protective cover 36 during the limiting process. The guiding design of the opening of the limiting sleeve 38 facilitates installation and positioning.
[0020] Furthermore, the rectangular block 34 is shaped to match the inner wall of the rectangular box 31. The rectangular block 34 is slidably connected to the inner wall of the rectangular box 31. The sliding cooperation between the rectangular block 34 and the rectangular box 31 makes the movement of the card block 35 smoother.
[0021] Furthermore, the rectangular box 31 has movable openings on both the left and right sides, and the locking block 35 passes through the movable opening and moves. The movable opening structure avoids interference with the movement of the locking block and extends the service life of the mechanism; the tight gap design prevents dust from entering the box.
[0022] Example 2 See Figures 1 to 4 Furthermore, based on Embodiment 1, the disassembly mechanism 2 includes a push shaft 21, which is fixedly connected to the front of the rectangular block 34. An insert block 22 is rotatably connected to the outer wall of the push shaft 21. A limit shaft 23 is fixedly connected to the front of the rectangular box 31. The linkage design of rotating the insert block 22 to drive the push shaft 21 enables the protective cover to be unlocked with one hand. The limit shaft 23 fixes the insert block 22 to prevent accidental reset.
[0023] Furthermore, the insert 22 has a slot inside, and the size of the slot is larger than that of the limiting shaft 23. The matching structure between the slot of the insert 22 and the limiting shaft 23 simplifies the operation process; the through design of the push shaft 21 ensures transmission stability.
[0024] Furthermore, the push shaft 21 passes through the insert block 22, and the rectangular box 31 has a slot on its front side. The push shaft 21 passes through the slot, allowing the push shaft 21 to move through the slot.
[0025] In actual operation, when this device is in use, if it is necessary to disassemble the protective cover 36 and inspect and maintain the wiring position of the switching power supply body 1, the plug 22 can be rotated first. The plug 22 rotates along the axis of the push shaft 21, and then pushes the two push shafts 21 closer to each other. The push shafts 21 can drive the rectangular block 34 to move. The rectangular block 34 compresses the spring 33, and the locking block 35 can be pulled out from the inside of the limiting sleeve 38. After the locking block 35 is completely pulled out from the inside of the limiting sleeve 38, the plug 22 is rotated again so that the plug 22 can be locked into the inside of the limiting shaft 23. Thus, under the mutual cooperation of the plug 22 and the limiting shaft 23, the locking block 35 can be guaranteed not to be pushed by the elastic action of the spring 33. Then the protective cover 36 can be removed to facilitate further inspection and maintenance of the wiring position of the switching power supply body 1.
[0026] After the maintenance is completed, the insert 22 can be rotated again to prevent it from getting stuck on the outer wall of the limiting shaft 23. Then, the compressed spring 33 will push the rectangular block 34 to move, so that the rectangular block 34 can drive the locking block 35 to be inserted into the inside of the limiting sleeve 38, thereby limiting the limiting sleeve 38 and realizing the limiting installation of the protective cover 36, ensuring the stability of the protective cover 36 during the protection process.
[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
