Description

Technical Field

[0001] This utility model relates to the field of transformers, and specifically to a transformer that is easy to assemble and disassemble. Background Technology

[0002] Transformers operate on the principle of electromagnetic induction. A transformer mainly consists of an insulating frame, an iron core, and two sets of coils: a primary coil and a secondary coil. When alternating current is applied to the primary coil, the iron core generates an alternating magnetic field, which induces an electromotive force in the secondary coil. Currently, transformers are typically mounted on circuit boards by soldering their leads to the board for fixation. However, when a transformer fails, it is usually the internal structure that is damaged, with the leads rarely being damaged. This necessitates disassembling and soldering the transformer down, then soldering a new one onto it. This results in inefficient and time-consuming assembly and disassembly of transformers.

[0003] To address the aforementioned technical problems, Chinese utility model patent CN 219626430 U discloses a transformer, including a transformer body 1. A first fixing rod 2 is symmetrically installed at the lower end of the transformer body 1. Several plug-in rods 3 are installed at the lower end of the first fixing rod 2. A second fixing rod 11 is located below the first fixing rod 2. Several plug-in slots 12 are formed at the upper end of the second fixing rod 11, corresponding to the positions of the plug-in rods 3. Several pins 13 are installed at the lower end of the second fixing rod 11. The first fixing rod 2 and the second fixing rod 11 are fixed together by a pull ring 8, a pull plate 7, a pull rod 6, a compression spring 9, a mating block 10, and a locking hole 101. Disassembly and assembly only require removing and reassembling the transformer body, eliminating the need for repeated welding and desoldering, saving time and effort. However, in actual production, the following problems were found with the above-mentioned technical solution: the design of the structure below the transformer body increases the overall height of the transformer, making it unsuitable for the current miniaturized design requirements of existing housings, and the transformer body is prone to falling off during use. Therefore, there is a need for a transformer that reduces the overall height of the transformer and has a robust connection. Utility Model Content

[0004] The purpose of this invention is to provide a transformer that is easy to assemble and disassemble, in order to solve the technical problems of high overall height and unstable connection of transformers in the prior art.

[0005] To achieve the above objectives, the present invention provides a transformer that is easy to assemble and disassemble, employing the following technical solution: A transformer that is easy to assemble and disassemble includes a transformer body and a mating block. The transformer body includes an insulating frame, a primary winding, a secondary winding, and an iron core. The insulating frame has a first protrusion and a second protrusion, and pins are provided on both the first and second protrusions. The mating block has a receiving groove for accommodating the first and second protrusions. The bottom of the receiving groove is used for contact and limiting engagement with the first and second protrusions. A conductive rod is provided on the mating block for welding and fixing to a circuit board, and the conductive rod has a socket for conductive connection of the pins. An elastic locking structure is provided between the transformer body and the mating block to fix the transformer body to the mating block.

[0006] The number of mating blocks is two. The mating blocks include a first mating block and a second mating block that are arranged in a one-to-one correspondence with the first protrusion and the second protrusion. Each mating block is provided with the receiving groove and the conductive rod.

[0007] The elastic locking structure includes an elastic plate disposed on each protrusion, the elastic plate being provided with locking protrusions, and the groove wall of the receiving groove being provided with locking holes for the locking protrusions to engage.

[0008] The pin is an L-shaped pin, which is integrally fused to the corresponding protrusion. The horizontal section of the L-shaped pin is used for the cable connector of the corresponding wire group to be wound and connected, and the vertical section of the L-shaped pin is used for conductive insertion with the conductive rod. The first protrusion and the second protrusion are both provided with grooves for the cable connector of the corresponding wire group to pass through.

[0009] Each mating block has a guide plate in its receiving groove for cooperating with the guide movement of the wire trough.

[0010] The upper part of the guide plate is symmetrically provided with inclined surfaces to facilitate the insertion of the guide plate into the wire groove.

[0011] After the transformer body and the mating block are installed in place, there is a gap between the upper end of the guide plate and the bottom of the cable tray to avoid the cables in the cable tray.

[0012] The first and second mating blocks have grooves above the receiving grooves to avoid the horizontal section of the L-shaped pin on the corresponding protrusion and the cable wrapped around the horizontal section.

[0013] The beneficial effects of this utility model are as follows: During installation, the mating block is soldered to the circuit board via a conductive rod. The transformer body is then inserted into the mating block, and a conductive connection is achieved through a pin-hole conductive connection structure formed by the pins on the transformer body and the conductive rod on the mating block. Furthermore, the presence of the receiving groove can offset the dimensions occupied by the existing first and second protrusions, reducing the overall height of the transformer and mating block in the prior art. A flexible locking structure ensures a secure and stable connection between the transformer body and the mating block. During disassembly, the transformer body can be easily replaced by simply detaching it from the mating block using the flexible locking structure. Attached Figure Description

Detailed Implementation

[0015] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0016] It should be noted that, unless otherwise defined, the technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The use of "belonging" in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this invention.

[0017] An embodiment of this utility model of a transformer that is easy to assemble and disassemble, such as... Figures 1-4As shown, the transformer includes a transformer body and a mating block. The transformer body includes an insulating frame 1, a primary winding group 2, a secondary winding group 3, and an iron core 4. The insulating frame 1, primary winding group 2, secondary winding group 3, and iron core 4 are all existing technologies and will not be described in detail in this embodiment. The lower end of the insulating frame 1 has a first protrusion 5 and a second protrusion 6. Pins 7 are provided on both the first protrusion 5 and the second protrusion 6. The pins 7 are L-shaped pins, which are integrally fused to the corresponding protrusions. That is, the L-shaped pins are placed in the mold in advance during the injection molding of the insulating frame, and the two are fused together after solidification.

[0018] The mating block is provided with a receiving groove for accommodating the first protrusion and the second protrusion. The bottom of the receiving groove is used for contact and limiting engagement with the first protrusion and the second protrusion. The mating block is provided with a conductive rod 15, which is used for soldering and fixing to the circuit board. The conductive rod 15 has a socket for conductive connection of the pin 7. In this embodiment, there are two mating blocks. Specifically, the mating blocks include a first mating block 8 and a second mating block 9, which are arranged in a one-to-one correspondence with the first protrusion 5 and the second protrusion 6. Each mating block is provided with the aforementioned receiving groove 13 and conductive rod 15.

[0019] An elastic locking structure is provided between the transformer body and the mating block to fix the transformer body to the mating block. In this embodiment, the elastic locking structure includes an elastic plate 10 disposed on each protrusion, a locking protrusion 11 disposed on the elastic plate 10, and a locking hole 18 disposed on the groove wall of the receiving groove 13 for the locking protrusion 11 to engage. Specifically, each protrusion is provided with a groove 21, and the protruding portion outside the groove forms the elastic plate 10. In this embodiment, the horizontal section 19 of the L-shaped pin 7 is used for winding and connecting the cable connector of the corresponding wire group, and the vertical section 20 of the L-shaped pin is used for conductive insertion with the conductive rod 15.

[0020] Both the first protrusion 5 and the second protrusion 6 are provided with cable grooves 12 for the cable connectors of the corresponding cable groups to pass through. Each mating block's receiving groove 13 is provided with a guide plate 14 for guiding and moving with the cable groove 12, serving a positioning and installation function. The upper part of the guide plate 14 is symmetrically provided with inclined surfaces 16 to facilitate insertion of the guide plate 14 into the cable groove 12. After the transformer body and the mating block are installed in place, there is a gap between the upper end of the guide plate and the bottom of the cable groove to avoid the cables in the cable groove. The receiving grooves of the first and second mating blocks have grooves 17 above the groove walls to avoid the horizontal sections of the L-shaped pins on the corresponding protrusions and the cables wound around those horizontal sections.

[0021] In use, the mating block is first soldered onto the circuit board, specifically via conductive rods. Then, the transformer body is inserted into the mating block. Conductive connection is achieved through a pin-hole conductive connection structure formed by the pins on the transformer body and the conductive rods on the mating block. Simultaneously, a flexible locking structure secures the transformer body to the mating block. For disassembly, simply use the flexible locking structure to detach the transformer body from the mating block. For example, the transformer body can be removed by pressing the locking protrusion against the locking hole to squeeze the elastic plate and disengage it. A new transformer body can then be directly replaced. Subsequent disassembly and assembly require no further soldering, making the process convenient.
