Its function is to convert a voltage at a certain level into the voltage or current required by the user through different architectures.
[0003] In power electronic equipment, switching power supplies are important power supply devices. Their wiring process is usually cumbersome and prone to errors or loose connections due to improper operation. Traditional switching power supply wiring methods often require manual tightening of screws to secure the wires, which not only increases the difficulty of operation but also makes the wiring unreliable due to human factors. Therefore, a switching power supply structure that facilitates wiring is proposed. Utility Model Content

When the limiting rod leaves the inner side of the limiting groove, the pin and the socket are separated.
[0013] Preferably, the above-mentioned clamping mechanism includes a support frame, the support frame having a first groove inside, a slide plate slidably connected to the inner side of the first groove, a pressure plate fixed to the bottom of the slide plate, and a rubber layer adhered to the bottom of the pressure plate.
[0014] Preferably, the above-mentioned fixture has a second sliding groove inside, the outer side of the pressure plate is slidably connected to the inner side of the second sliding groove, the top of the slide plate is fixed with a pull rod that passes through the top of the support frame, the outer side of the pull rod is sleeved with a spring, and the two ends of the spring are respectively connected to one side of the slide plate and the first sliding groove.

[0028] Example
[0029] Please see Figure 1-5 This utility model provides a technical solution: a switching power supply structure that is easy to wire, including a switching power supply body 1, a power cord 6 connected to one end of the switching power supply body 1, a heat dissipation hole 5 on one side of the switching power supply body 1, and a fan 7 installed on the inner wall of the switching power supply body 1 opposite to the heat dissipation hole 5; when the fan 7 is working, it blows outside air towards the inside of the switching power supply body 1, and the air exchanges heat with the electronic components inside the switching power supply body 1, blowing the high-temperature air out from the heat dissipation hole 5; a connecting component 2 is provided on one side of the switching power supply body 1, and a wire 3 is provided on one side of the connecting component 2; a mounting foot 4 is installed at the bottom of the switching power supply body 1, and a screw hole is provided on one side of the mounting foot 4.
[0030] The connecting component 2 includes a guiding mechanism, a clamping mechanism and a plastic connecting rod 24. One end of the plastic connecting rod 24 is fixed with a pin 25 that is electrically connected to the wire 3. Several fixing brackets 21 are fixed on one side of the switching power supply body 1. The fixing brackets 21 are made of insulating plastic. A through hole is opened on one side of the fixing bracket 21, and a socket 214 is installed inside the through hole.
[0031] The guiding mechanism includes a limiting rod 28 made of insulating plastic. A second magnet 27 is embedded at one end of the limiting rod 28. The hand is held on the outside of the limiting rod 28 and the plastic connecting rod 24, and the limiting rod 28 is inserted into the limiting groove 213. At the same time, the plastic connecting rod 24 is inserted into the through hole. A limiting groove 213 is opened on one side of the fixing bracket 21. A first magnet 26 is embedded in the inner wall of the limiting groove 213. One side of the limiting rod 28 is fixed to one side of the plastic connecting rod 24, which is also made of insulating plastic. When the limiting rod 28 is inserted into the limiting groove 213, the first magnet 26 and the second magnet 27 attract each other. At this time, the pin 25 is inserted into the socket 214, and the pin 25 and the socket 214 are electrically connected. When the limiting rod 28 leaves the limiting groove 213, the pin 25 and the socket 214 are separated.
[0032] The clamping mechanism includes a support frame 22, which has a first groove 212 inside. The support frame 22 is made of insulating plastic. A sliding plate 210 is slidably connected to the inside of the first groove 212. The sliding plate 210, pressure plate 29, and pull rod 23 are all made of insulating plastic. The pressure plate 29 is fixed to the bottom of the sliding plate 210, and a rubber layer is bonded to the bottom of the pressure plate 29. A second groove 215 is opened inside the fixing frame 21. Under the elastic force of the spring 211, the sliding plate 210 is pushed to slide inside the first groove 212, while the pull rod 23 drives the pressure plate 210 to slide. The plate 29 slides inside the second slide groove 215, so that the bottom of the pressure plate 29 is pressed against the outside of the plastic connecting rod 24. The outside of the pressure plate 29 is slidably connected to the inside of the second slide groove 215. The top of the slide plate 210 is fixed with a pull rod 23 that passes through the top of the support frame 22. A spring 211 is sleeved on the outside of the pull rod 23. The two ends of the spring 211 are respectively connected to one side of the slide plate 210 and the first slide groove 212. The rubber layer increases the friction between the pressure plate 29 and the plastic connecting rod 24 to prevent the pin 25 from loosening after it is engaged with the socket 214.
[0033] One side of the mounting bracket 21 is fixed to one side of the switching power supply body 1, the bottom of the support bracket 22 is fixed to the top of the mounting bracket 21, the input end of the socket 214 is electrically connected to the output end of the switching power supply body 1, and one side of the plastic connecting rod 24 is fixed to one side of the wire 3.
[0034] In this embodiment, the switching power supply body 1 is a PSA500-600-I model manufactured by Hangzhou Pinshen Power Technology Co., Ltd. Since the structure and operating principle of this model of switching power supply body 1 are existing technologies, their structure and operating principle will not be described in detail here.
[0035] Working principle: First, connect the screw hole through hole bolt of mounting foot 4 to the operating table. When fan 7 is working, it blows the outside air to the inside of the switching power supply body 1. The air exchanges heat with the electronic components inside the switching power supply body 1 and blows the hot air out from the heat dissipation hole 5.
[0036] When the switching power supply body 1 is working, the power line 6 is connected to the high voltage DC power supply. The switching power supply body 1 converts the high voltage DC power supply into a high frequency pulse signal by controlling the conduction and cutoff of the switching transistor. The high frequency pulse signal is sent to the primary winding of the high frequency transformer. The transformer uses the principle of electromagnetic induction to transfer the electrical energy on the high voltage side to the low voltage side, and at the same time realizes the voltage transformation. On the low voltage side, the high frequency pulse signal is converted into DC voltage by the rectifier circuit. The DC voltage is further smoothed by the filter circuit to eliminate the high frequency components in the pulse signal and obtain a stable low voltage DC output voltage. The low voltage DC output voltage output terminal is electrically connected to the socket 214.
[0037] When it is necessary to connect the wire 3 at the output end, simply pull the lever 23 upwards to make the pressure plate 29 leave the inside of the through hole. At this time, take the wire 3, hold it with your hand on the outside of the limiting rod 28 and the plastic connecting rod 24, insert the limiting rod 28 into the limiting groove 213, and at the same time make the plastic connecting rod 24 into the inside of the through hole. When the first magnet 26 and the second magnet 27 attract each other, the pin 25 is inserted into the inside of the socket 214. The guide mechanism provides directional limit when the pin 25 and the socket 214 are connected.
[0038] When the pulling force of the lever 23 is released, the spring force of the spring 211 pushes the slide plate 210 to slide inside the first slide groove 212. At the same time, the lever 23 drives the pressure plate 29 to slide inside the second slide groove 215, so that the bottom of the pressure plate 29 is pressed tightly against the outside of the plastic connecting rod 24. Meanwhile, the rubber layer increases the friction between the pressure plate 29 and the plastic connecting rod 24, preventing the pin 25 from loosening after it is engaged with the socket 214.
[0039] In summary, by pulling the lever 23 upwards to move the pressure plate 29 away from the inside of the through hole, and holding the limit rod 28 and the plastic connecting rod 24 on the outside, the limit rod 28 is inserted into the limit groove 213 and the plastic connecting rod 24 is inserted into the through hole, ensuring that the pin 25 and the socket 214 can be correctly aligned. When the first magnet 26 and the second magnet 27 are magnetically attracted, the pin 25 is inserted into the inside of the socket 214. The guide mechanism provides directional limit when the pin 25 and the socket 214 are connected, ensuring that the pin 25 can be accurately inserted into the socket 214, avoiding tilting or jamming of the pin 25 during insertion. The use of magnetic force to achieve automatic alignment and auxiliary connection further improves the reliability of the connection.
[0040] When the tension of the lever 23 is released, under the elastic force of the spring 211, the slide plate 210 and the lever 23 drive the pressure plate 29 to automatically reset and press against the outside of the plastic connecting rod 24. No manual operation is required to tighten it again. The bottom of the pressure plate 29 is pressed against the outside of the plastic connecting rod 24, which can further fix the position of the wire 3 connection and prevent the pin 25 and the socket 214 from loosening due to vibration, shaking or other reasons during use. This ensures the reliability of the connection and helps maintain the normal operation of the entire circuit system.
