Description
Technical Field
[0001] This utility model relates to the field of surface mount transformers, and more particularly to a multifunctional surface mount transformer. Background Technology
[0002] Multifunctional surface mount transformers are miniaturized, high-performance electronic components that encapsulate the coil and core together as a single unit, featuring a compact structure and small footprint.
[0003] There are various types of transformers on the market, and the multi-functional surface mount transformer is one of them. The copper core windings inside the surface mount transformer are generally installed with screws, making it difficult to disassemble quickly. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of slow disassembly speed in existing technologies by proposing a multifunctional patch transformer.
[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:
[0006] A multifunctional surface mount transformer includes a pair of frames, each frame having a pair of slots. A pair of locking blocks are engaged within each pair of slots, with each pair of locking blocks fully conforming to the inner walls of the slots. Each frame also has a pair of sliding grooves and a pair of movably mounted sliding plates, each pair of sliding plates corresponding one-to-one with the two pairs of sliding grooves. Each sliding plate has a fixed slider, and each pair of sliders is slidably connected to the two pairs of sliding grooves. Each groove has a fixed spring, with one end of each pair of springs fixedly connected to the two pairs of sliders.
[0007] Preferably, each of the card blocks has a pair of fixing slots, and each fixing slot has multiple elongated slots.
[0008] Preferably, an iron core is provided between a pair of the frame bodies, the surface of which is wound with copper wire, and a skeleton is fixedly provided on each of the frame bodies.
[0009] Preferably, the skeletons are all cylindrical, with the end faces of a pair of skeletons touching each other, and the outer walls of the skeletons touching the inner walls of the iron core.
[0010] Preferably, each side of the frame is provided with a storage slot, and each storage slot is fixed with a heat-conducting plate, and each heat-conducting plate is fixed with multiple heat dissipation fins.
[0011] Preferably, a pair of fixing plates are fixedly provided at the lower end of the frame, and multiple cable trays are provided on the upper and lower surfaces of the fixing plates, and multiple pins are fixedly provided on the fixing plates.
[0012] Preferably, the pin adopts a 90° bent structure.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this utility model, the sliding plate slides to both sides, and the sliding plate drives the slider to slide along the slide groove. The slider compresses the spring until the sliding plate completely disengages from the contact with the card block. The clamp is used to clamp the card block out through the fixing groove. The long groove prevents slippage during clamping. After the card block is disengaged from the frame, a pair of frames and the iron core can be directly disassembled. The screw installation method is eliminated, making the assembly and disassembly of the surface mount transformer simpler and speeding up the maintenance rate of the surface mount transformer.
[0015] 2. In this utility model, the core of the surface mount transformer generates a certain amount of heat during use. The heat is transferred to the heat conduction plate through the frame, and the heat conduction plate transfers the heat to multiple heat dissipation fins. The heat dissipation fins quickly transfer the heat to the air, thereby cooling the surface mount transformer. This prevents the surface mount transformer from generating excessively high temperatures, provides corresponding protection for the surface mount transformer, and increases the service life of the device.
[0016] 3. In this utility model, the 90° bent pins allow the surface mount transformer to fit better on the circuit board, greatly improving the stability of the pins and making them less prone to bending deformation during use. Attached Figure Description

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.
[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] Example: This example provides a multifunctional surface mount transformer, see [link to example]. Figure 1-4 Specifically, it includes a pair of frame bodies 1, each frame body 1 having a pair of slots 11, and a pair of locking blocks 12 locking within each pair of slots 11, with the locking blocks 12 completely fitting against the inner walls of the slots 11. Each frame body 1 also has a pair of sliding grooves 13, and each frame body 1 has a pair of movable sliding plates 14, with each pair of sliding plates 14 corresponding to one pair of sliding grooves 13. Each sliding plate 14 has a fixed slider 15, and the two pairs of sliders 15 slide relative to the two pairs of sliding grooves 13. The connection is as follows: springs 16 are fixedly installed in the slide groove 13, and one end of each pair of springs 16 is fixedly connected to each pair of sliders 15. Each block 12 has a pair of fixing grooves 2, and multiple long grooves 21 are opened in each fixing groove 2. An iron core 3 is provided between a pair of frame bodies 1. Copper wire 31 is wound on the surface of the iron core 3. A skeleton 32 is fixedly installed on each frame body 1. The skeleton 32 is cylindrical. The end faces of a pair of skeletons 32 are in contact with each other, and the outer wall of the skeleton 32 is in contact with the inner wall of the iron core 3.
[0026] Slide the sliding plate 14 to both sides. The sliding plate 14 drives the slider 15 to slide along the slide groove 13. The slider 15 compresses the spring 16 until the sliding plate 14 completely disengages from the contact with the locking block 12. Use a clamp to clamp the locking block 12 out through the fixing groove 2. The long groove 21 prevents slippage during clamping. After the locking block 12 is separated from the frame 1, the pair of frames 1 and the iron core 3 can be directly disassembled. The screw installation method is eliminated, making the assembly and disassembly of the surface mount transformer simpler and speeding up the maintenance rate of the surface mount transformer.
[0027] Each side of the frame 1 has a storage slot 4, and each storage slot 4 has a heat-conducting plate 41 fixedly installed inside the storage slot 4. Each heat-conducting plate 41 has multiple heat dissipation fins 42 fixedly installed on the heat-conducting plate 41.
[0028] During the use of the surface mount transformer, the core 3 will generate a certain amount of heat. The heat is transferred to the heat conduction plate 41 through the frame 1. The heat conduction plate 41 transfers the heat to multiple heat dissipation fins 42. The heat dissipation fins 42 quickly transfer the heat to the air, thereby cooling the surface mount transformer. This prevents the surface mount transformer from generating excessively high temperatures, provides corresponding protection for the surface mount transformer, and increases the service life of the device.
[0029] A pair of fixing plates 5 are fixedly installed at the lower end of the frame 1. Multiple cable trays 51 are opened on the upper and lower surfaces of the fixing plates 5. Multiple pins 52 are fixedly installed on the fixing plates 5. The pins 52 adopt a 90° bent structure.
[0030] The cable tray 51 can organize and arrange the connecting wires connected to the pin 52. The 90° bend of the pin 52 can make the surface mount transformer fit better on the circuit board, greatly improving the stability of the pin 52 and making the pin 52 less prone to bending deformation during use.
[0031] Specifically, the working principle and operation method of this utility model are as follows:
[0032] Slide the sliding plate 14 to both sides. The sliding plate 14 drives the slider 15 to slide along the slide groove 13. The slider 15 compresses the spring 16 until the sliding plate 14 completely disengages from the contact with the locking block 12. Use a clamp to clamp the locking block 12 out through the fixing groove 2. The long groove 21 prevents slippage during clamping. After the locking block 12 is separated from the frame 1, the pair of frames 1 and the iron core 3 can be directly disassembled. The screw installation method is eliminated, making the assembly and disassembly of the surface mount transformer simpler and speeding up the maintenance rate of the surface mount transformer.
[0033] During the use of the surface mount transformer, the core 3 will generate a certain amount of heat. The heat is transferred to the heat conduction plate 41 through the frame 1. The heat conduction plate 41 transfers the heat to multiple heat dissipation fins 42. The heat dissipation fins 42 quickly transfer the heat to the air, thereby cooling the surface mount transformer. This prevents the surface mount transformer from generating excessively high temperatures, provides corresponding protection for the surface mount transformer, and increases the service life of the device.
[0034] The 90° bend of pin 52 allows the surface mount transformer to fit better on the circuit board, greatly improving the stability of pin 52 and making it less prone to bending deformation during use.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
