Description

Technical Field

[0001] This invention relates to the field of electronic transformer technology, specifically to an electronic transformer with a self-locking mounting device. Background Technology

[0002] An electronic transformer is a power conversion device that uses power electronic conversion technology to convert industrial frequency AC power into high frequency AC power through switching circuits, high-frequency transformers, rectifiers, and filters. It then converts the output voltage and frequency to meet the required specifications. It eliminates the bulky iron core structure of traditional industrial frequency transformers and features small size, light weight, high efficiency, low heat generation, and good voltage regulation. It can perform functions such as voltage boosting, voltage reduction, isolation, and voltage regulation, and is widely used in power supply systems for power adapters, LED drivers, home appliances, industrial control equipment, new energy sources, and various electronic devices.

[0003] Electronic transformers with self-locking installation devices integrate an automatic locking and positioning structure on the basis of traditional electronic transformers, eliminating the need for additional fasteners. Through its own elastic buckles, guide limits, or self-locking mechanisms, it can directly and quickly connect with the mounting base, frame, or housing to achieve axial and radial locking, effectively preventing loosening, displacement, and vibration-induced detachment. It eliminates complex assembly steps such as bolts and nuts, improving installation efficiency and structural stability, while ensuring reliable electrical connections. It is suitable for industrial control, power equipment, and other scenarios with high requirements for seismic resistance and assembly efficiency.

[0004] However, the existing electronic transformer with a self-locking mounting device has the following shortcomings:

[0005] Currently available electronic transformers with self-locking installation devices generally suffer from a dilemma in balancing locking force and structural stability. Some, in order to ensure the firmness of the welded feet, prevent the electronic transformer from moving significantly even after it has been released from the self-locking state. Most, in pursuit of ease of installation, have locking structures that are usually not rigid enough and have large gaps between the parts. Under vibration conditions, they are prone to loosening, shaking, or even displacement, resulting in poor installation stability and reduced electrical connection stability, which increases the failure rate and maintenance costs of subsequent electronic products.

[0006] Therefore, we propose an electronic transformer with a self-locking mounting device to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an electronic transformer with a self-locking installation device. During installation, the electronic transformer is first pried open by removing the retaining plates on both sides of the base plate. The transformer is then aligned with the sliding column and column groove and inserted downwards. The retaining plates are released to allow it to rub against the side wall. As the transformer moves downwards, the meshing of the gear blocks drives the gears and rotating rod to rotate, causing the torsion spring to deform and store energy, gradually increasing the clamping force on the retaining plates. The short metal leg is precisely inserted into the welding ring through the funnel-shaped guide opening. Once in place, the retaining plate is pressed against the top by the torsion spring. A ratchet and pawl mechanism prevents reverse ejection. A secondary locking is achieved through the pull rod, retaining strip, and retaining groove to prevent loosening due to severe vibration. When the transformer is pressed down, the rubber plate deforms and pushes the short metal leg, improving the reliability of the electrical connection. Ultimately, this achieves fast, self-locking, and highly stable installation. This solution solves the problem of balancing convenience and robustness in traditional self-locking structures, preventing loosening and displacement, while simplifying the installation process, facilitating overall disassembly and assembly, and improving maintenance efficiency.

[0020] 1. During the installation of the electronic transformer in this invention, first, the clamping plates on both sides of the base plate are opened, the transformer is aligned with the sliding column and column groove, and then inserted downwards. The clamping plates are released to allow it to rub against the side wall of the transformer. During the downward movement of the transformer, the gear and rotating rod are rotated by the meshing of the toothed blocks, causing the torsion spring to deform and store energy, gradually increasing the clamping force on the clamping plate. The short metal leg is precisely inserted into the welding ring through the funnel-shaped guide port. After the transformer is in place, the clamping plate is pressed against the top under the action of the torsion spring. At the same time, the ratchet and pawl mechanism prevents it from reversing and popping out. Then, the rotating rod and clamping plate are locked a second time by the cooperation of the pull rod, the clamping strip and the clamping groove to prevent loosening under severe vibration. When the transformer is pressed down, the rubber plate deforms and pushes the short metal leg, enhancing the reliability of the electrical connection. Finally, the installation is completed quickly, self-locking and highly stable. This solves the problem that the convenience and firmness of traditional self-locking are mutually exclusive. At the same time, it avoids the problems of easy loosening and displacement of traditional self-locking structures and the relatively cumbersome self-locking method. It also realizes the free detachment of the entire electronic transformer, improving the convenience of maintenance. Attached Figure Description

The mounting base plate 201 is provided with multiple welding rings 230 on the inner side of the mounting base plate 201. Sliding columns 202 are provided on both sides of the electronic transformer sample 1. The inner side of the sliding column 202 is provided with a groove 203. The inner side of the groove 203 is provided with multiple tooth blocks 204. The top two sides of the mounting base plate 201 are provided with The structure includes a vertical beam 205 with a groove 206 on its inner side. A sliding column 202 slides within the groove 206. A rotating rod 207 is rotatably connected to the inner side of the vertical beam 205. A gear 208 is mounted on the outer side of the rotating rod 207, located inside the vertical beam 205 and meshing with multiple gear blocks 204. A second wheel groove 231 is formed at the top of the vertical beam 205, with a ratchet 213 mounted inside the groove 231. The ratchet 213 is mounted on the outer side of the rotating rod 207, and a pawl 214 is rotatably connected to the inner side of the second wheel groove 231, meshing with the ratchet 213.

A spring plate 232 is installed on the top of the second wheel groove 231, and a pressure spring 215 is installed on the bottom of the spring plate 232. The bottom of the pressure spring 215 is installed on the top of the pawl 214. A locking plate 209 is rotatably connected to the outside of the rotating rod 207. Both sides of the locking plate 209 are provided with ring grooves 210. Two spring holes 211 are provided on the outside of the rotating rod 207. The two spring holes 211 correspond to the two ring grooves 210 respectively. Two torsion springs 212 are sleeved on the outside of the locking plate 209. One end of the two torsion springs 212 is installed on the inside of the spring holes 211 respectively, and the other end of the two torsion springs 212 is installed on the outside of the locking plate 209.

[0032] The overall effect of Embodiment 1 is as follows: When installing the electronic transformer, firstly, the clamping plates 209 on both sides of the mounting base plate 201 are pushed aside. Holding the electronic transformer, the sliding column 202 is aligned with the column groove 206 on the mounting base plate 201. Then, the electronic transformer is inserted from top to bottom. After releasing the clamping plates 209 on both sides, one end of the clamping plate 209 is pressed against both sides of the electronic transformer and maintains friction with it. As the electronic transformer continues to be inserted downward into the inner side of the vertical beam 205, the toothed blocks 204 in the groove 203 inside the sliding column 202 drive the transformer through meshing. Gear 208 rotates inside the vertical beam 205. The rotating gear 208 drives the spring hole 211 on the rotating rod 207 to rotate. At this time, the torsion spring 212 connected inside the spring hole 211 deforms under the action of rotation and stores elastic potential energy, providing power for subsequent locking and resetting. As multiple tooth blocks 204 continuously drive gear 208 and rotating rod 207 to rotate, the torsion spring 212 continuously stores energy, and the force on the clamping plate 209 gradually increases, so that the clamping force of the clamping plate 209 on the outside of the electronic transformer gradually increases. Before it is fully in place, Align the short metal legs of the electronic transformer with the funnel-shaped guide opening 227. Guided by the funnel-shaped guide opening 227, the short metal legs are quickly and accurately inserted into the welding ring 230. After the electronic transformer is fully in place, the clamping plate 209 rotates under the action of the torsion spring 212, and its end presses against the top of the electronic transformer to achieve clamping. During this process, while the rotating rod 207 rotates, the ratchet 213 on its outer surface rotates synchronously. After the electronic transformer is fully in place, the pawl 214 limits the ratchet 213 to prevent the torsion spring 212 from driving the rotating rod 207. 7. Reverse gear 208 to prevent the electronic transformer from popping upwards. When this device is connected to the circuit board, the mounting base 201 is fixed to the circuit board with screws, and the solder ring 230 is fixed to the circuit with solder. The short metal leg on the electronic transformer model 1 is electrically connected by inserting into the solder ring 230. Since the short leg is not substantially fixed to the circuit board, it can freely insert and detach from the solder ring 230, so that the entire electronic transformer model 1 can be completely detached from the circuit board, making maintenance and repair more convenient.

[0033] Example 2, according to Figure 3 - Figure 8As shown, pads 226 are installed on both sides of the top of the mounting base plate 201. Multiple funnel-shaped guide openings 227 are provided on the top of the pads 226. A rubber plate 228 is placed in the middle of the top of the mounting base plate 201, located at the bottom of the electronic transformer sample 1. A groove 229 is provided at the bottom of the pads 226, and the two sides of the rubber plate 228 are located inside the grooves 229 on both sides. A spring hole 218 is provided on the inner side of one end of the rotating rod 207. One end of the rotating rod 207 is provided with a first slot 219, the other side of the rotating rod 207 is provided with a second slot 220, the outer side of the plate 209 is provided with a third slot 224, the second slot 220 corresponds to the third slot 224, the inner side of the spring hole 218 is provided with a rotating shaft 221, the other end of the rotating shaft 221 is provided with a tension spring 222, the other end of the tension spring 222 is provided with a locking strip 223, and the other end of the locking strip 223 is provided with a pull rod 225.

[0034] The overall effect of Embodiment 2 is as follows: to ensure the reliable operation of the pawl 214, the pressure spring 215 at the top presses the pawl 214 against the ratchet 213 to prevent vibration from causing the pawl 214 to disengage. After the above actions are completed, pull the lever 225 to pull the locking strip 223 out of the first locking slot 219. Rotate the lever 225 to align the locking strip 223 with the second locking slot 220. After releasing the lever 225, under the action of the tension spring 222, the locking strip 223 is locked into the second locking slot 220 and the corresponding third locking slot 224, fixing the rotating rod 207 to the locking plate 209. Before this, although the locking plate 209 presses the electronic transformer under the action of the torsion spring 212, and the ratchet 213 and pawl 214 can prevent... While preventing reverse rotation, the transformer still rotates backward under severe vibration, failing to guarantee sufficient stability. Once the locking plate 209 is fixed to the rotating rod 207, the locking plate 209 is locked along with the rotating rod 207, preventing rotation and improving overall stability. This completes the installation of the electronic transformer, achieving stable self-locking. When the electronic transformer is pressed down, the rubber plate 228 is slightly compressed and deformed, extending inward into the plate groove 229. The extended part contacts the short metal leg in the funnel-shaped guide opening 227. Through its own deformation, the short metal leg is pushed to both sides, improving the tightness of the contact between the short metal leg and the welding ring 230, preventing vibration from causing the electrical connection to loosen, and further enhancing the overall installation stability of the electronic transformer.

[0035] The working principle of the entire device is as follows: When installing the electronic transformer sample 1, firstly, the clamping plates 209 on both sides of the mounting base plate 201 are pushed open to both sides. The electronic transformer sample 1 is then manually held, and the sliding column 202 is aligned with the column groove 206 on the mounting base plate 201. The electronic transformer sample 1 is then inserted from top to bottom. At this time, the clamping plates 209 are released, so that one end of the clamping plate 209 is tightly pressed against both sides of the electronic transformer sample 1 and continuously rubs against them. As the electronic transformer sample 1 continues to be inserted downwards into the inner side of the vertical beam 205, the gear 204 inside the groove 203 on the inner side of the sliding column 202 meshes with the groove, causing the gear 208 to rotate inside the vertical beam 205. The rotating gear 208 drives the spring hole 211 on the rotating rod 207. As the device rotates, the torsion spring 212 connected to the inner side of the spring hole 211 deforms due to the rotation, storing elastic potential energy to provide driving force for subsequent locking and resetting. With multiple toothed blocks 204 continuously driving the gear 208 and rotating rod 207 to rotate several times, the torsion spring 212 continues to store energy, and the pressure exerted by the torsion spring 212 on the clamping plate 209 continuously increases, causing the clamping plate 209 to gradually increase its pressure on the outside of the electronic transformer sample 1. Before fully resetting, the short metal leg of the electronic transformer sample 1 is aligned with the funnel-shaped guide opening 227, and its short metal leg is quickly and accurately inserted into the welding ring 230 through the funnel-shaped guide opening 227. After the electronic transformer sample 1 is fully resetting, the clamping plate 209 is actuated by the torsion spring 212. This causes one end of the clamping plate 209 to rotate to the top of the electronic transformer sample 1 and press it down. During this process, while the rotating rod 207 rotates, the ratchet 213 on the other side of its outer surface continues to rotate. After the electronic transformer sample 1 is fully returned to its original position, it is limited by the pawl 214 to prevent the torsion spring 212 from reversing due to its own potential energy, the rotating rod 207 and gear 208 from rotating, and the electronic transformer sample 1 from being ejected in the opposite direction to the inside of the vertical beam 205. In order to ensure the timeliness and stability of the pawl 214's response, it is pressed down by the pressure spring 215 at its top, so that the pawl 214 is tightly attached to the ratchet 213, preventing the pawl 214 from shifting due to vibration during subsequent use. After this action is completed, in order to further increase the stability of this structure... By pulling the lever 225, the locking strip 223 is pulled out of the inner range of the first locking slot 219. At this time, the lever 225 is rotated, causing the locking strip 223 to rotate and rotate to the position corresponding to the second locking slot 220. Then, the lever 225 is released, and the elasticity of the tension spring 222 causes the locking strip 223 to engage with the inner side of the second locking slot 220 and the corresponding third locking slot 224, thereby fixing the rotating rod 207 and the locking plate 209. Before this operation, although the locking plate 209 is continuously pressed downward by the torsion spring 212, and the ratchet 213 and pawl 214 prevent the rotating rod 207 and the locking plate 209 from reversing, the locking plate 209 can still rotate backward when subjected to significant vibration.Therefore, the electronic transformer sample 1 cannot be made to be in a strong stable state. When the clamping plate 209 is fixed to the rotating rod 207, the clamping plate 209 is affected by the rotating rod 207, and the synchronous ratchet 213 and pawl 214 benefit, so that the clamping plate 209 cannot rotate, thereby further improving its stability. At this time, the installation of the electronic transformer sample 1 is completed, and a stable self-locking effect is achieved. Among them, when the electronic transformer sample 1 is pressed down, the rubber plate 228 is pressed and slightly deformed, so that the two sides of the rubber plate 228 are respectively... The rubber plate 228 extends deeper into the inner side of the groove 229, and the extended portion contacts the short metal leg of the electronic transformer sample 1 inside the funnel-shaped guide opening 227. At this point, its extension pushes the short metal leg of the electronic transformer sample 1 to both sides, increasing the contact and force between the short metal leg and the inner side of the welding ring 230. This prevents subsequent vibrations of electronic products from causing loosening or shaking of the electrical connection. Furthermore, this pushing and pressurizing method further ensures the overall installation stability of the electronic transformer sample 1.
