Description

Technical Field

[0001] This utility model relates to the field of electronic transformers, and in particular to a split-type electronic transformer. Background Technology

[0002] A split-type electronic transformer is a specially designed power device that divides a traditional integrated electronic transformer into multiple independent parts. These parts typically include high-voltage and low-voltage sides, which are connected by specific electrical connections. This design makes the transformer more flexible and convenient to transport, install, and maintain, and is particularly suitable for applications with limited space or requiring distributed power supply. Split-type electronic transformers operate based on the principle of electromagnetic induction, enabling efficient transmission and conversion of electrical energy. They play a vital role in various fields and are an indispensable key component in the modern electronics industry.

[0003] In existing technologies, current electronic transformers exhibit the following problems during practical use:

[0004] Because most electronic transformers on the market are fixed by welding and screws, it is difficult to disassemble them after welding. Screws require auxiliary tools for fixing and disassembling electronic transformers. Since electronic transformers are small in size, the screws and screwdrivers used for installation are also small, making it difficult to install and fix them. All of these factors increase the difficulty of installing electronic transformers. Furthermore, it is not convenient to disassemble them when they need to be repaired or replaced in the future, thus causing inconvenience to the installation, disassembly and use of electronic transformers.

[0005] Because electronic transformers lack external protective measures, they are prone to damage when subjected to impacts, external dust, or electromagnetic interference during use. This not only affects the normal use of the electronic transformer but also shortens its service life. Utility Model Content

[0006] The main objective of this invention is to provide a split-type electronic transformer that can effectively solve the problems in the background technology.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A split-type electronic transformer includes an electronic transformer body and a mounting base. The electronic transformer body is fixedly connected to the top surface of the mounting base via a mounting mechanism, which includes side plates, fixing plates, screws, trapezoidal plates, clamping plates, triangular plates, and compression springs. Side plates are fixedly connected to both sides of the top surface of the mounting base, and a set of symmetrical fixing plates are fixedly connected inside the side plates. The screws are movably connected to the inside of the side plates and located between the fixing plates via rotating rods at both ends. The trapezoidal plates are movably connected to the screws via screw holes on the top surface. The clamping plates are movably connected to the fixing plates via connecting rods on the inner side walls, and triangular plates are fixedly connected to the inner end of the connecting rods. The compression springs are sleeved on the outside of the connecting rods and fixedly connected between the fixing plates and the triangular plates. An electromagnetic shielding cover is also sleeved on the outside of the electronic transformer body.

[0009] Furthermore, a set of symmetrical side plates are fixedly installed on the top surface of the mounting base, and slots are respectively provided on the front and rear walls of the side plates.

[0010] Furthermore, the inner walls of the electromagnetic shielding cover are respectively fixedly installed with inserts corresponding to the slots, and the inserts are inserted into the slots.

[0011] Furthermore, a set of symmetrical slots are provided on the side wall of the side plate, and an inner cavity communicating with the slots is provided inside the side plate. A set of symmetrical fixing plates are fixedly installed inside the inner cavity, and a connecting hole is provided on the side wall of the fixing plate. Sliding grooves are provided on the two inner side walls of the inner cavity, and a rotating hole is provided on the top and bottom surfaces of the inner cavity.

[0012] Furthermore, insert plates are fixedly installed on the left and right side walls of the electronic transformer body, and the insert plates are inserted into the sockets. The side walls of the insert plates are provided with snap-fit ​​openings.

[0013] Furthermore, rotating rods are fixedly installed at the upper and lower ends of the screw, and the rotating rods are movably installed in the rotating holes. A knob is fixedly installed at the top of the upper rotating rod. A screw hole is opened on the top surface of the trapezoidal plate and is threadedly connected to the screw through the screw hole. Sliding strips are fixedly installed on both sides of the trapezoidal plate and are movably installed in the sliding groove. The trapezoidal plate presents an isosceles trapezoidal shape.

[0014] Furthermore, a connecting rod is fixedly installed on the inner side wall of the card plate, and the connecting rod is inserted into the connecting hole. A right-angled triangular plate is fixedly installed on the inner end of the connecting rod, and a compression spring is sleeved on the outside of the connecting rod and fixedly installed between the triangular plate and the opposite wall of the fixed plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, the installation mechanism involves inserting the insert plates on both sides of the electronic transformer body into the sockets. Rotating the knob drives the screw to rotate, causing the trapezoidal plate to move downwards through the screw hole along the screw, pressing the triangular plates on both sides below. This causes the triangular plates to compress the compression springs, tightening them and pushing the connecting rod through the fixing plate, thus inserting the locking plate into the socket. This fixes the electronic transformer body onto the top surface of the mounting base, facilitating quick installation. Reverse rotation of the knob moves the trapezoidal plate upwards, relieving pressure on the triangular plates. The reverse elastic extension force of the compression springs pushes the triangular plates, causing them to move through the connecting rod and pull the locking plate out of the socket. The transformer body can be removed from the mounting base for repair or replacement by removing the middle part, which facilitates the disassembly and use of the transformer body. Finally, the electromagnetic shielding cover is inserted into the outside of the transformer body through the insert strip. The electromagnetic shielding cover can prevent the transformer body from being damaged by impacts or dust during use. According to the material characteristics of the electromagnetic shielding cover, it can shield the external electromagnetic field and prevent the transformer body from being damaged by electromagnetic interference. This effectively protects the transformer body, ensures its normal use, and extends its service life. Attached Figure Description

[0024] 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.

[0025] like Figure 1 - Figure 6 As shown, a split-type electronic transformer includes an electronic transformer body 1 and a mounting base 2. The electronic transformer body 1 is fixedly connected to the top surface of the mounting base 2 via a mounting mechanism 3. The mounting mechanism 3 includes a side plate 8, a fixing plate 12, a screw 16, a trapezoidal plate 19, a clamping plate 22, a triangular plate 24, and a compression spring 25. The side plates 8 are fixedly connected to both sides of the top surface of the mounting base 2, and a set of symmetrical fixing plates 12 are fixedly connected inside the side plates 8. The screw 16 is movably connected to the inside of the side plates 8 and located between the fixing plates 12 via rotating rods 17 at both ends. The trapezoidal plate 19 is movably connected to the screw 16 via a screw hole 20 on the top surface. The clamping plate 22 is movably connected to the fixing plate 12 via a connecting rod 23 on the inner side wall. The triangular plate 24 is fixedly connected to the inner end of the connecting rod 23. The compression spring 25 is sleeved on the outside of the connecting rod 23 and fixedly connected between the fixing plate 12 and the triangular plate 24. An electromagnetic shielding cover 4 is also sleeved on the outside of the electronic transformer body 1.

[0026] like Figure 5 As shown, a set of symmetrical side plates 8 are fixedly installed on the top surface of the mounting base 2, and slots 9 are respectively opened on the front and rear walls of the side plates 8. The slots 9 on the side plates 8 are used to cooperate with the installation of the electromagnetic shielding cover 4.

[0027] like Figure 3 As shown, the inner walls of the electromagnetic shielding cover 4 are respectively fixedly installed with inserts 7 corresponding to the slots 9, and the inserts 7 are inserted into the slots 9. After the inserts 7 are inserted into the slots 9, the electromagnetic shielding cover 4 can be fitted onto the outside of the electronic transformer body 1, and the electromagnetic shielding cover 4 can protect the electronic transformer body 1.

[0028] like Figure 5As shown, a set of symmetrical sockets 10 are provided on the side wall of the side plate 8. The sockets 10 are used to cooperate with the positioning and installation of the electronic transformer body 1. The side plate 8 has an inner cavity 11 that communicates with the sockets 10. The inner cavity 11 is used to accommodate the components of the mounting mechanism 3 and the movement of the components. A set of symmetrical fixing plates 12 are fixedly installed inside the inner cavity 11. The side wall of the fixing plate 12 has a connecting hole 13. The connecting hole 13 on the side wall of the fixing plate 12 can ensure the left and right movement of the connecting rod 23. The two inner side walls of the inner cavity 11 have sliding grooves 14. The sliding grooves 14 are used to cooperate with the slider 21 to achieve sliding operation. The top and bottom surfaces of the inner cavity 11 have rotation holes 15. The rotation holes 15 are used to cooperate with the rotating rod 17 to achieve rotation operation.

[0029] like Figure 2 As shown, plug plates 5 are fixedly installed on the left and right side walls of the electronic transformer body 1, and the plug plates 5 are inserted into the plug socket 10. The side wall of the plug plate 5 is provided with a slot 6. Inserting the plug plate 5 into the plug socket 10 can position the electronic transformer body 1 on the top surface of the mounting base 2. The slot 6 on the side wall of the plug plate 5 is used to cooperate with the slot plate 22 to achieve limited installation.

[0030] like Figure 3 and Figure 6 As shown, rotating rods 17 are fixedly installed at the upper and lower ends of the screw 16, and the rotating rods 17 are movably installed in the rotating hole 15. A knob 18 is fixedly installed at the top of the upper rotating rod 17. A screw hole 20 is opened on the top surface of the trapezoidal plate 19 and is threadedly connected to the screw 16 through the screw hole 20. Slide strips 21 are fixedly installed on the two side walls of the trapezoidal plate 19 and are movably installed in the slide groove 14. The trapezoidal plate 19 has an isosceles trapezoidal shape. Rotating the knob 18 drives the screw 16 to rotate through the rotating rod 17, so that the trapezoidal plate 19 moves up and down along the screw 16 through the screw hole 20, which can apply or release the squeezing force on the triangular plate 24.

[0031] like Figure 3 and Figure 6 As shown, a connecting rod 23 is fixedly installed on the inner wall of the clamping plate 22, and the connecting rod 23 is inserted into the connecting hole 13. A right-angled triangular plate 24 is fixedly installed on the inner end of the connecting rod 23, and a compression spring 25 is sleeved on the outside of the connecting rod 23 and fixedly installed between the triangular plate 24 and the opposite wall of the fixing plate 12. When the triangular plate 24 is subjected to compressive force, it will force the compression spring 25 to perform a compression operation, and push the clamping plate 22 through the connecting rod 23 to insert the clamping plate 22 into the bayonet 6, so as to achieve the purpose of limiting and fixing the electronic transformer body 1.

[0032] The specific operating principle of the mounting mechanism 3 and the electromagnetic shielding cover 4 in conjunction with the electronic transformer body 1 is as follows:

[0033] After the mounting base 2 is pre-fixed to the base surface of the required installation location of the electronic transformer body 1, when installing the electronic transformer body 1, insert the insert plates 5 on both sides of the electronic transformer body 1 into the insert slots 10 opened on the side wall of the side plate 8, and then rotate the knob 18 located on the top surface of the side plate 8. The knob 18 will drive the rotating rod 17 to rotate in the rotating hole 15, so that the rotating rod 17 drives the screw 16 to rotate, allowing the isosceles trapezoidal plate 19 to move downward along the screw 16 through the screw hole 20 opened on the top surface. During the movement, the sliding strips 21 installed on the two side walls of the trapezoidal plate 19 will slide in the sliding groove 14. Furthermore, the trapezoidal plate 19 will compress the right-angled triangular plates 24 located on both sides below. After being compressed, the triangular plates 24 will force the compression spring 25, which is fitted outside the connecting rod 23 and fixed between the fixing plate 12 and the triangular plates 24, to tighten. The triangular plates 24 will push the connecting rod 23 through the connecting hole 13 opened on the side wall of the fixing plate 12. The connecting rod 23 will push the locking plate 22 to move outward until the locking plate 22 is inserted into the slot 6 opened on the side wall of the insert plate 5 and the knob 18 cannot be turned. This completes the installation and fixing of the electronic transformer body 1. Then, the electromagnetic shielding is applied. The electromagnetic shielding cover 4 is fitted onto the outside of the electronic transformer body 1, allowing the inserts 7 on both sides of the inner wall of the electromagnetic shielding cover 4 to be inserted into the slots 9. This allows the electromagnetic shielding cover 4 to be fitted, preventing damage to the electronic transformer body 1 from external factors such as impacts, dust, and electromagnetic interference during use. When disassembly of the electronic transformer body 1 is required, the electromagnetic shielding cover 4 can be removed from the outside of the electronic transformer body 1. Then, the knob 18 is rotated in the opposite direction, causing the screw 16 to rotate via the rotating rod 17, allowing the trapezoidal plate 19 to pass smoothly through the screw hole 20. After the screw 16 moves upward and stops pressing on the triangular plates 24 on both sides, the compression spring 25 will perform an elastic recovery and extension operation, and push the triangular plates 24 outward and inward. This causes the triangular plates 24 to drive the clamping plate 22 into the inner cavity 11 through the connecting rod 23, until the clamping plate 22 is removed from the clamping slot 6. The electronic transformer body 1 can then be removed from the top surface of the mounting base 2. This solves the problems of the existing electronic transformer body 1 being inconvenient to disassemble and use and lacking protection, which makes it prone to damage. This achieves the purpose of ensuring the normal use of the electronic transformer body 1 and extending its service life.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
