Abstract
Description
Technical Field
[0001] This utility model belongs to the field of high-frequency transformer technology, and specifically relates to a rust-resistant high-frequency transformer. Background Technology
[0002] High-frequency transformers are electronic transformers with high operating frequencies. To be precise, they are electronic transformers with operating frequencies higher than 20kHz (or 10kHz). They are mainly used in high-frequency switching power supplies as high-frequency switching power supply transformers, and are also used in high-frequency inverter power supplies and high-frequency inverter welding machines as high-frequency inverter power supply transformers.
[0003] The working principle of a high-frequency transformer is based on electromagnetic induction. When an alternating current flows through the primary coil, an alternating magnetic flux is generated in the iron core (or magnetic core), inducing a voltage (or current) in the secondary coil. A transformer consists of an iron core (or magnetic core) and coils. The coils have two or more windings; the winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils. After prolonged operation, the surface of a high-frequency transformer often accumulates high temperatures. If this heat cannot be effectively and promptly dissipated from the transformer surface, it will penetrate into the transformer's interior, causing internal components to also be affected by high temperatures. This continuous high-temperature environment accelerates the aging process of the transformer's internal materials, damages its insulation performance, and may lead to electrical faults. Utility Model Content
[0004] The purpose of this invention is to provide a corrosion-resistant high-frequency transformer, addressing the problem in existing equipment where, after prolonged operation, the surface of the transformer often accumulates high temperatures. If this heat cannot be effectively and promptly dissipated from the transformer surface, it will penetrate into the transformer's interior, causing internal components to also suffer from high temperatures. This sustained high-temperature environment accelerates the aging process of the transformer's internal materials, damages its insulation performance, and may lead to electrical faults.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rust-resistant high-frequency transformer, comprising a magnetic core and a connecting plate installed inside the magnetic core, wherein the surface of the connecting plate is provided with terminals, a secondary winding is installed on one side of the magnetic core, a primary winding is provided at the bottom end of the secondary winding, and pins are installed on the bottom surface of the connecting plate;
[0006] The magnetic core is connected to heat sinks on both sides, heat sinks are installed on the surface of the heat sinks, docking plates are connected to both ends of the heat sinks, docking seats are connected to the surface of the docking plates, an elastic plate is connected to the inner wall of the opening at one end of the docking plate, a linkage plate is connected to the other end of the elastic plate, and a buckle is connected to the other side of the linkage plate.
[0007] As a preferred embodiment of the rust-resistant high-frequency transformer of this utility model, the secondary winding is a galvanized copper sheet, and the primary winding is a Teflon triple-insulated wire coil.
[0008] As a preferred embodiment of the rust-proof high-frequency transformer of this utility model, the heat sink plate is fitted and connected to the docking seat through a docking plate, and both the heat sink plate and the heat sink fins are made of copper.
[0009] As a preferred embodiment of the rust-proof high-frequency transformer of this utility model, the elastic plate is made of flexible PVC material, and the elastic plate and the buckle form an elastic linkage structure.
[0010] As a preferred embodiment of the rust-proof high-frequency transformer of this utility model, the inner side of the docking seat is connected to the surface of the magnetic core, and a slot is provided near the buckle of the docking seat. The buckle and the slot on the side of the docking seat form an interlocking structure.
[0011] As a preferred embodiment of the rust-proof high-frequency transformer of this utility model, the inner wall of the magnetic core is connected with a winding post, which passes through the secondary winding and the primary winding and is located inside the two magnetic cores.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention connects the mating plates at both ends of the heat sink to the mating seats on both sides of the magnetic core, thereby assembling the heat sink on both sides of the magnetic core. Simultaneously, the snap-fit mechanism inside the mating plate presses against the linkage plate, causing the elastic plate to deform. The snap-fit then engages with the opening on one side of the mating seat, facilitating the stable installation of the heat sink. At the same time, the bottom surface of the heat sink contacts the top of the secondary winding of the high-frequency transformer, guiding and transferring the heat generated by the winding assembly, and then dissipating it, ensuring the normal temperature around the high-frequency transformer and preventing damage to the high-frequency transformer due to overheating.

[0021] 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.
[0022] Please see Figure 1-5 The present invention provides the following technical solution: a rust-proof high-frequency transformer, including a magnetic core 1 and a connecting plate 2 installed inside the magnetic core 1. The surface of the connecting plate 2 is equipped with a terminal block 3. A secondary winding 4 is installed on one side of the magnetic core 1. A primary winding 5 is provided at the bottom end of the secondary winding 4. A pin 51 is installed on the bottom surface of the connecting plate 2.
[0023] Heat sinks 6 are connected to both sides of the magnetic core 1. Heat sinks fins 7 are installed on the surface of the heat sinks 6. Abutment plates 8 are connected to both ends of the heat sinks 6. Abutment seats 9 are connected to the surface of the abutment plates 8. An elastic plate 10 is connected to the inner wall of the opening at one end of the abutment plates 8. A linkage plate 11 is connected to the other end of the elastic plate 10. A buckle 12 is connected to the other side of the linkage plate 11.
[0024] Preferably, the secondary winding 4 is made of galvanized copper sheet, and the primary winding 5 is made of Teflon triple-insulated wire disc.
[0025] In practical use, the secondary winding 4 made of galvanized copper sheet is used to ensure that the high-frequency transformer has a rust-proof effect inside.
[0026] Preferably, the heat sink 6 is fitted and connected to the docking seat 9 via the docking plate 8, and both the heat sink 6 and the heat sink fins 7 are made of copper.
[0027] In practical use, the heat sink 6 and heat sink 7 are used to facilitate the dissipation of high temperature inside the high-frequency transformer, ensuring the service life of the high-frequency transformer.
[0028] Preferably, the elastic plate 10 is made of flexible PVC material, and the elastic plate 10 and the buckle 12 form an elastic linkage structure.
[0029] In practical use, the reciprocating deformation of the elastic plate 10 drives the buckle 12 on one side of the linkage plate 11 to move, thereby causing the buckle 12 to engage and connect to the slot on the side of the docking seat 9.
[0030] Preferably, the inner side of the docking seat 9 is connected to the surface of the magnetic core 1, and a slot is provided on the docking seat 9 near the buckle 12. The buckle 12 and the slot on the side of the docking seat 9 form an interlocking structure.
[0031] In practical use, the buckle 12 is fitted into the slot on the side of the docking seat 9, which makes it easy to install the heat sink 6 stably.
[0032] Preferably, the inner wall of the magnetic core 1 is connected to a winding post 101, which passes through the secondary winding 4 and the primary winding 5 and is located inside the two magnetic cores 1.
[0033] In practical use, by passing the winding post 101 through the secondary winding 4 and the primary winding 5, the two magnetic cores 1 are assembled, ensuring that the high-frequency transformer has a small size and high efficiency.
[0034] The working principle of this utility model is as follows: First, the secondary winding 4 installed inside the high-frequency transformer is made of galvanized copper sheet, which improves the anti-rust effect. By connecting the docking plates 8 at both ends of the heat sink 6 with the docking seats 9 on both sides of the magnetic core 1, the heat sink 6 is assembled on both sides of the magnetic core 1. At the same time, the buckle 12 inside the docking plate 8 presses the linkage plate 11, and the elastic plate 10 deforms. The elastic plate 10 rebounds and causes the buckle 12 to fit into the opening on one side of the docking seat 9, thus facilitating the stable installation of the heat sink 6. At the same time, the bottom surface of the heat sink 6 contacts the top of the secondary winding 4 of the high-frequency transformer, guiding and transferring the heat generated by the winding assembly, and then dissipating it to ensure the normal temperature around the high-frequency transformer and avoid damage to the high-frequency transformer due to overheating. In addition, the winding post 101 passes through the secondary winding 4 and the primary winding 5, so that the two magnetic cores 1 are stably connected, ensuring the high-frequency transformer has a small size and high efficiency.
