[0030] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by referring to examples. In the following description, many specific details are set forth to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring these embodiments. Additionally, all embodiments can be used in combination with each other.

[0031] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a new type of leadless electronic transformer that is easy to install. The electronic transformer includes: a transformer housing 1, a bottom plate 5, and positioning buckles 7.

[0032] Both ends of the transformer housing 1 are fixedly connected with mounting brackets 2. The lower surface of the mounting bracket 2 is fixedly connected with a plug-in board 3, and a positioning groove 22 is formed on the surface of the plug-in board 3;

[0033] Specifically, both ends of the upper surface of the bottom plate 5 are fixedly connected with support seats 6. A plug-in slot 11 is formed inside the support seat 6. A chamfer is provided at the open end of the plug-in slot 11. Weight-reducing grooves 10 are formed on the surfaces of both the support seat 6 and the plug-in board 3. A sliding hole 13 is formed on the surface of the support seat 6. The plug-in board 3 is movably inserted into the inner cavity of the plug-in slot 11 and is adapted thereto. The chamfer is provided to ensure that the plug-in board 3 can be inserted into the inner cavity of the plug-in slot 11 more smoothly from top to bottom. After the plug-in board 3 is inserted into the inner cavity of the plug-in slot 11, the plug-in board 3 cannot slide in the horizontal direction;

[0034] In addition, four positioning buckles 7 are provided, and the four positioning buckles 7 are respectively arranged at both ends of the two support seats 6. The positioning buckles 7 are slidably installed in the inner cavity of the sliding hole 13. The positioning buckles 7 can slide horizontally. A sleeve 14 is fixedly connected to the surface of the support seat 6, and the sleeve 14 corresponds to the sliding hole 13. The middle part of the positioning buckle 7 movably passes through the sleeve 14 and is adapted thereto. Moreover, in order to reduce the friction force when the positioning buckle 7 slides, a ball 27 is movably embedded in the lower surface of the middle part of the positioning buckle 7. The first sliding groove 18 and the second sliding groove 19 are formed inside the sleeve 14. The size of the first sliding groove 18 is the same as that of the sliding hole 13. The second sliding groove 19 is provided for guiding the sliding of the positioning buckle 7.

[0035] Furthermore, a positioning end 20 is fixedly connected to one end of the positioning buckle 7. The first sliding groove 18 is adapted to the positioning end 20. Therefore, the positioning end 20 can only slide in the inner cavity of the first sliding groove 18 and the inner cavity of the sliding hole 13. The upper surface of the positioning end 20 is inclined. The positioning end 20 is located in the inner cavity of the positioning groove 22 and is adapted to it. When the positioning buckle 7 slides, the positioning end 20 at one end of the positioning buckle 7 can slide along the inner cavities of the first sliding groove 18 and the sliding hole 13 and finally insert into the inner cavity of the positioning groove 22, so that after the plug-in board 3 is inserted into the inner cavity of the plug-in groove 11, its position is fixed and it will not slide in the vertical direction and cause separation from the inner cavity of the plug-in groove 11.

[0036] Secondly, a thrust spring 17 is arranged at the other end of the positioning buckle 7. A fixing plate 15 is fixedly connected to the outside of the support seat 6. A convex block 16 with a hollow structure is arranged in the middle of the fixing plate 15. One end of the thrust spring 17 is fixedly installed in the inner cavity of the convex block 16. A spring installation groove 25 is formed on the other end surface of the positioning buckle 7. A spring sleeve column 26 is fixedly connected to the inner cavity of the spring installation groove 25. The end of the thrust spring 17 is located in the inner cavity of the spring installation groove 25 and is fixedly sleeved with the spring sleeve column 26. Therefore, the thrust spring 17 can generate a thrust on the positioning buckle 7, so that after the positioning end 20 at one end of the positioning buckle 7 is inserted into the inner cavity of the positioning groove 22, it will not easily separate from the inner cavity of the positioning groove 22.

[0037] Moreover, a reinforcing connecting plate 4 is arranged on one side of the plug-in board 3. The upper end of the reinforcing connecting plate 4 is fixedly connected to the mounting frame 2. A reinforcing limiting groove 23 is formed on the surface of the reinforcing connecting plate 4. An avoidance groove 24 is formed on the lower end surface of the reinforcing connecting plate 4. The avoidance groove 24 is buckled on the outer side of the upper end of the sleeve 14. The setting of the avoidance groove 24 is used to prevent the reinforcing connecting plate 4 from colliding with the sleeve 14 during the downward movement. A horizontally arranged reinforcing limiting plate 21 is fixedly connected to the upper end of the positioning buckle 7. The reinforcing limiting plate 21 is slidably inserted into and adapted to the reinforcing limiting groove 23. A reinforcing connecting groove 12 is formed on the upper end surface of the support seat 6. The lower end of the reinforcing connecting plate 4 movably penetrates through the inner cavity of the reinforcing connecting groove 12 and extends below the reinforcing connecting groove 12. Therefore, when the mounting frame 2 moves vertically downward, the reinforcing connecting plate 4 can pass through the inner cavity of the reinforcing connecting groove 12, and when the positioning buckle 7 moves horizontally, the reinforcing limiting plate 21 can be inserted into the inner cavity of the reinforcing limiting groove 23, thereby further strengthening the position of the mounting frame 2 and preventing the position of the mounting frame 2 from moving.

[0038] Furthermore, a connecting rod 8 is arranged outside the support base 6. Two ends of the connecting rod 8 are respectively fixedly connected to two adjacent positioning buttons 7. A cam post 9 is sleeved outside the middle part of the connecting rod 8, and a rubber pad is arranged between the cam post 9 and the connecting rod 8. Therefore, when the cam post 9 is rotated, one end of the cam post 9 will abut against the side surface of the reinforcing connecting plate 4, so that the positioning button 7 moves reversely and compresses the thrust spring 17. When the positioning button 7 slides reversely, the positioning end 20 at one end of the positioning button 7 can be separated from the positioning groove 22, ensuring that the plug-in plate 3 can be vertically pulled out from the inner cavity of the plug-in groove 11, and further facilitating the removal of the transformer housing 1.

[0039] When installing the device, first move the mounting bracket 2 from top to bottom, driving the plug-in plate 3 to insert into the inner cavity of the plug-in groove 11. At the same time, the reinforcing connecting plate 4 passes through the reinforcing connecting groove 12. During the downward sliding of the plug-in plate 3 in the inner cavity of the plug-in groove 11, the plug-in plate 3 presses the inclined surface on the positioning end 20 at one end of the positioning button 7. At this time, the positioning button 7 slides horizontally, and the reinforcing limiting plate 21 on the positioning button 7 does not hinder the downward sliding of the reinforcing connecting plate 4 until the plug-in plate 3 slides to the bottom of the plug-in groove 11. At this time, the positioning button 7 corresponds to the positioning groove 22, and the positioning button 7 slides under the thrust of the thrust spring 17, so that the positioning end 20 at one end of the positioning button 7 inserts into the inner cavity of the positioning groove 22 to prevent the plug-in plate 3 from separating from the inner cavity of the plug-in groove 11. In addition, when the positioning button 7 slides, the reinforcing limiting plate 21 can also insert into the inner cavity of the reinforcing limiting groove 23, further strengthening the fixation of the position of the mounting bracket 2.

[0040] When disassembling, rotate the cam post 9 so that the end of the cam post 9 abuts against the surface of the reinforcing connecting plate 4. After the cam post 9 is abutted by the reinforcing connecting plate 4, it drives the positioning button 7 to slide reversely and compresses the thrust spring 17. At this time, the positioning end 20 at one end of the positioning button 7 is separated from the inner cavity of the positioning groove 22, and the reinforcing limiting plate 21 on the positioning button 7 is separated from the inner cavity of the reinforcing limiting groove 23. Then, by vertically moving the transformer housing 1 upward, the plug-in plate 3 can be pulled out from the inner cavity of the plug-in groove 11, and the reinforcing connecting plate 4 is separated from the reinforcing connecting groove 12. Therefore, the device is more convenient to disassemble.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
