Description

Technical Field

[0001] The utility model relates to the technical field of general parts of transformers or inductors, and in particular to a high-efficiency, low-voltage, high-current, and high-frequency transformer. Background Art

[0002] High-power power supplies are widely used in industry, among which high-frequency transformers are very important components of high-power power supplies. The Chinese utility model patent, authorization announcement number "CN214123668U", discloses a low-voltage, high-current high-frequency transformer, including a primary high-voltage winding, a secondary low-voltage winding and a magnetic core. The primary high-voltage winding is arranged inside the magnetic core, and the secondary low-voltage winding is connected to the primary high-voltage winding and exposed outside the magnetic core; the primary high-voltage winding includes at least one group of copper foils, and the secondary low-voltage winding includes at least six groups of copper foils, and the six groups of copper foils are wound in parallel.

[0003] The above technical solution uses a primary high-voltage winding composed of a group of copper foils to make the low-voltage, high-current, high-frequency transformer have the function of high voltage and low current; the secondary low-voltage winding composed of six groups of copper foils is used to make the low-voltage, high-current, high-frequency transformer have the function of low voltage and high current, so that the transformer can work in a high-frequency environment of more than 100KHz, with wide practicality and low loss. The low-voltage, high-current, high-frequency transformer uses copper foil to make the winding, so that it has good heat dissipation, avoiding the occurrence of large heat and large magnetic leakage during the operation of the transformer. In order to prevent rainwater from entering the low-voltage, high-current, high-frequency transformer, a rain shield is set outside the low-voltage, high-current, high-frequency transformer to cover the heat dissipation holes. However, since the low-voltage, high-current, high-frequency transformer is set outside, dust from the outside enters the low-voltage, high-current, high-frequency transformer through the heat dissipation holes, which is easy to cause damage to the low-voltage, high-current, high-frequency transformer. Therefore, a dust net needs to be set to prevent dust from entering. Since the rain shield covers the dust net, it is extremely inconvenient to clean the dust on the dust net. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a high-efficiency, low-voltage, high-current, high-frequency transformer, which can solve the problem that the rain shield covers the dustproof net, making it extremely inconvenient to clean the dust on the dustproof net.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A high-efficiency low-voltage high-current high-frequency transformer, comprising a low-voltage high-current high-frequency transformer body;

[0007] The dustproof and rainproof components are arranged on the main body of the low-voltage, high-current, and high-frequency transformer. The dustproof and rainproof components include a base, a rainproof cover, two springs, two hemispheres, two limit columns, two connecting plates, a sliding hole, a sliding rod, a screw, a threaded hole one, a semicircular plate, a groove one, a threaded hole two and a dustproof net. The base is on the main body of the low-voltage, high-current, and high-frequency transformer. The groove one is arranged on the base, the threaded hole two is arranged inside the groove one, and the threaded hole one is arranged on the semicircular plate. There are four dustproof and rainproof components, and the four dustproof and rainproof components are all arranged in the upper groove of the main body of the low-voltage, high-current, and high-frequency transformer.

[0008] The utility model also includes the following features:

[0009] Preferably, the inner surfaces of the four threaded holes one are respectively threadedly connected to the surfaces of the corresponding screws, and the inner surfaces of the four threaded holes two are respectively threadedly connected to the surfaces of the corresponding screws.

[0010] Preferably, the surfaces of the four semicircular plates are in contact with the surface of the corresponding groove one, and the four rain covers are adhered to the corresponding semicircular plates, respectively.

[0011] Preferably, the four dustproof nets are respectively adhered to the corresponding bases, and the four sliding holes are respectively arranged on the corresponding bases.

[0012] Preferably, the eight connecting plates slide inside the corresponding sliding holes respectively, one ends of the eight springs are adhered to the corresponding connecting plates respectively, and the other ends of the eight springs are adhered to the corresponding bases respectively.

[0013] Preferably, the four sliding rods are respectively adhered to the corresponding external brackets of the base, and the eight connecting plates slide along the corresponding sliding rods respectively.

[0014] Preferably, the eight limiting columns are respectively adhered to the corresponding connecting plates, and the eight hemispheres are respectively adhered to the corresponding limiting columns.

[0015] Preferably, the surface of the low-voltage, high-current, high-frequency transformer body is provided with four grooves 2, each of which has two limit grooves inside, and the inner surfaces of the eight limit grooves are in contact with the surfaces of the corresponding limit columns respectively.

[0016] The technical effects achieved by the utility model are:

[0017] (1) The high-efficiency, low-voltage, high-current, high-frequency transformer is provided with screws in the dust and rainproof assembly. By loosening the screws, the rainproof cover can be removed from the surface of the base, so that the rainproof cover and the dustproof net can be cleaned separately. This can avoid the problem that the rainproof cover blocks the dustproof net and it is difficult to clean the dust on the dustproof net, thereby improving the convenience of cleaning the dustproof net with the rainproof cover.

[0018] (2) In the high-efficiency low-voltage, high-current, high-frequency transformer, since the process of cleaning the dust screen and the rain cover is relatively slow, cleaning the rain cover and the dust screen one by one will delay the normal operation of the low-voltage, high-current, high-frequency transformer body too much. Therefore, two connecting plates in the dust and rainproof assembly are used to make the two connecting plates move relative to each other through external force, so that the rain cover and the dust screen can be removed from the surface of the low-voltage, high-current, high-frequency transformer body, and then the clean rain cover and the dust screen can be replaced and reinstalled on the low-voltage, high-current, high-frequency transformer body, so that multiple rain covers and multiple dust screens that need to be cleaned can be cleaned together, thereby minimizing the time when the low-voltage, high-current, high-frequency transformer body stops working and minimizing the power supply impact caused by stopping the low-voltage, high-current, high-frequency transformer body.

[0024] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically explained in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the scope of protection of the specific request of the utility model. As used in this article, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors;

[0025] Combination Figures 1 to 5 As shown, the specific features of the high-efficiency low-voltage high-current high-frequency transformer are described in detail below: A high-efficiency low-voltage high-current high-frequency transformer comprises a low-voltage high-current high-frequency transformer body 1;

[0026] The dustproof and rainproof assembly is arranged on the main body 1 of the low-voltage, high-current, and high-frequency transformer. The dustproof and rainproof assembly includes a base 2, a rainproof cover 3, two springs 4, two hemispheres 5, two limit columns 6, two connecting plates 7, a sliding hole 8, a sliding rod 9, a screw 10, a threaded hole 11, a semicircular plate 12, a groove 13, a threaded hole 2 14 and a dustproof net 15. The base 2 is on the main body 1 of the low-voltage, high-current, and high-frequency transformer. The groove 13 is arranged on the base 2. The threaded hole 2 14 is arranged inside the groove 13. The threaded hole 11 is arranged on the semicircular plate 12. There are four dustproof and rainproof assemblies, and the four dustproof and rainproof assemblies are all arranged on the main body 1 of the low-voltage, high-current, and high-frequency transformer.

[0027] The inner surfaces of the four threaded holes 11 are respectively threadedly connected to the surfaces of the corresponding screws 10 , and the inner surfaces of the four threaded holes 2 14 are respectively threadedly connected to the surfaces of the corresponding screws 10 .

[0028] The surfaces of the four semicircular plates 12 are in contact with the surfaces of the corresponding grooves 13 , respectively, and the four rain shields 3 are adhered to the corresponding semicircular plates 12 , respectively.

[0029] The four dustproof nets 15 are respectively adhered to the corresponding bases 2 , and the four sliding holes 8 are respectively arranged on the corresponding bases 2 .

[0030] The eight connecting plates 7 slide inside the corresponding sliding holes 8 respectively, one ends of the eight springs 4 are adhered to the corresponding connecting plates 7 respectively, and the other ends of the eight springs 4 are adhered to the corresponding bases 2 respectively.

[0031] The four slide bars 9 are respectively adhered to the corresponding external brackets of the base 2 , and the eight connecting plates 7 slide along the corresponding slide bars 9 .

[0032] The eight limiting columns 6 are respectively adhered to the corresponding connecting plates 7 , and the eight hemispheres 5 are respectively adhered to the corresponding limiting columns 6 .

[0033] The surface of the low-voltage, high-current, high-frequency transformer body 1 is provided with four grooves 2 17 , each of which has two limiting grooves 16 inside. The inner surfaces of the eight limiting grooves 16 are in contact with the surfaces of the corresponding limiting columns 6 .

[0034] When it is necessary to clean the dust net 15 and the rain cover 3, first, drive the two connecting plates 7 to move relative to each other. The relative movement of the two connecting plates 7 drives the corresponding limit columns 6 to move respectively. The relative movement of the two limit columns 6 drives the corresponding hemispheres 5 to move relative to each other. When the two hemispheres 5 move out of the corresponding groove 2 17, remove the base 2 from the surface of the low-voltage, high-current, high-frequency transformer body 1, then loosen the screws 10 with a tool, and then remove the semicircular plate 12 from the inside of the groove 13.

[0035] By setting the screw 10 in the dust and rain proof assembly and loosening the screw 10, the rain cover 3 can be removed from the surface of the base 2, so that the rain cover 3 and the dust net 15 can be cleaned separately. This can avoid the problem that the rain cover 3 blocks the dust net 15 and it is difficult to clean the dust on the dust net 15, thereby improving the convenience of cleaning the dust net 15 with the rain cover 3.

[0036] Since the process of cleaning the dustproof net 15 and the rainproof cover 3 is relatively slow, cleaning the rainproof cover 3 and the dustproof net 15 one by one will delay the normal operation of the low-voltage, high-current, high-frequency transformer main body 1 too much, so the two connecting plates 7 in the dustproof and rainproof assembly are used, and the two connecting plates 7 are moved relative to each other through external force, so that the rainproof cover 3 and the dustproof net 15 can be removed from the surface of the low-voltage, high-current, high-frequency transformer main body 1, and then the clean rainproof cover 3 and the dustproof net 15 are replaced and reinstalled on the low-voltage, high-current, high-frequency transformer main body 1, so that the multiple rainproof covers 3 and multiple dustproof nets 15 that need to be cleaned can be cleaned together, thereby minimizing the time when the low-voltage, high-current, high-frequency transformer main body 1 stops working, and minimizing the power supply impact caused by stopping the low-voltage, high-current, high-frequency transformer main body 1.

[0037] Working principle: When it is necessary to clean the dust net 15 and the rain cover 3, first, drive the two connecting plates 7 to move relative to each other, and the two connecting plates 7 respectively drive the corresponding limit columns 6 to move, and the relative movement of the two limit columns 6 respectively drives the corresponding hemispheres 5 to move relative to each other. When the two hemispheres 5 move out of the corresponding groove 2 17, remove the base 2 from the surface of the low-voltage, high-current, high-frequency transformer body 1, then loosen the screws 10 with a tool, and then remove the semicircular plate 12 from the inside of the groove 13.
