Description

Technical Field

[0001] This utility model relates to the field of high-frequency transformer technology, specifically to an anti-interference high-frequency transformer for electrical appliances. Background Technology

[0002] Anti-interference high-frequency transformers are power transformers with operating frequencies exceeding intermediate frequencies. 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. Their application range is quite wide.

[0003] Currently, most of the anti-interference high-frequency transformers used in existing electrical appliances are small-sized components. Therefore, they are often stacked together during actual transportation. However, the large stacking pressure can easily cause the pins inside the high-frequency transformer to fall off or deform, delaying subsequent use.

[0004] In recent years, with the further development of related technologies, existing technologies have proposed to detach the pins from the high-frequency transformer. During subsequent transportation, the pins are first removed and then reassembled upon arrival at the destination. Although this method can prevent the pins from falling off or deforming, the subsequent assembly operation is relatively troublesome and can easily delay the efficiency of use. Utility Model Content

The end of the drive shaft is fitted with a bearing seat fixed to the top of the protective shell through a bearing.

[0007] An L-shaped protective plate is connected to the middle of the drive shaft, and the L-shaped protective plate can protect the pins in the corresponding direction by using the central axis of the drive shaft as the rotation base axis. Several auxiliary baffles are installed on the surface of the L-shaped protective plate, and the auxiliary baffles can be connected to the surface of the pins by the flipping axis of the L-shaped protective plate. A locking component is provided between the two drive shafts.

[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] Please see Figures 1-5 An anti-interference high-frequency transformer for electrical appliances includes a winding 1 and an iron core clamp 2 fitted on the outside of the winding 1. Several pins 3 are installed on both sides of the top of the winding 1. A protective shell is fitted on the outside of the iron core clamp 2, and a drive shaft 4 is provided on both sides of the top of the protective shell. The end of the drive shaft 4 is fitted with a bearing seat fixed to the top of the protective shell through a bearing.

[0026] An L-shaped protective plate 5 is connected to the middle of the drive shaft 4, and the L-shaped protective plate 5 can protect the pins 3 in the corresponding direction by using the central axis of the drive shaft 4 as the rotation base axis. Several auxiliary baffles 6 are installed on the surface of the L-shaped protective plate 5, and the auxiliary baffles 6 can be connected to the surface of the pins 3 by the flipping axis of the L-shaped protective plate 5. A locking component is provided between the two drive shafts 4.

[0027] The locking component includes two composite spur gear plates 71 in opposite positions and two gear rings 72. The two gear rings 72 are respectively engaged with one end of the two composite spur gear plates 71, and the inner sides of the middle of the two gear rings 72 are respectively fixedly sleeved on the corresponding end surfaces of the two drive shafts 4. The bottom of the composite spur gear plates 71 is engaged with a slide rail 73 fixed to the top of the protective housing. The other end of each of the two composite spur gear plates 71 is provided with a clearance groove, and the two clearance grooves in opposite positions combine to form an installation space. A screw 74 is engaged in the installation space, and the two ends of the screw 74 respectively pass through... The other end of the two composite straight tooth plates 71 is threaded with a nut 75. The two nuts 75, which are in opposite positions, can close and lock the two composite straight tooth plates 71 during the process of meshing and supporting their respective screws 74. Both ends of the screws 74 are fitted with springs 76 and damping rings 77 that are movably sleeved in the installation space. The two ends of the springs 76 are respectively fixed to the surface of the other end of the composite straight tooth plate 71 and the inner wall of the corresponding clearance groove, thereby extending the damping and buffering effect of the L-shaped protective plate 5 and the composite straight tooth plate 71 during the flipping process.

[0028] In use, for the transportation requirements of the anti-interference high-frequency transformer formed by winding 1, core clamp 2, and multiple pins 3, the other ends of the two composite straight tooth plates 71 can be pinched first and the two composite straight tooth plates 71 can be moved close together under the guidance of their respective corresponding slide rails 73 until the two composite straight tooth plates 71 are attached together. During the movement of the two composite straight tooth plates 71, the two gear rings 72 simultaneously mesh with their respective composite straight tooth plates 71 and drive the corresponding L-shaped protective plates 5 to rotate synchronously through their respective corresponding drive shafts 4 until the two L-shaped protective plates 5 cover and protect the pins 3 set on both sides of the top of winding 1. The auxiliary baffles 6 inside the two L-shaped protective plates 5 contact their respective pins 3 to increase the compressive strength of the pins 3. Then, the screw 74 is fitted with the other end of the two composite straight tooth plates 71 with a preset clearance space. Then, the two 75 are threadedly connected to the two screws 74 to realize the limiting lock of the L-shaped protective plates 5 and the composite straight tooth plates 71.

[0029] Please see Figures 1-5Both the L-shaped protective plate 5 and the auxiliary baffle 6 are made of thermally conductive materials. Thus, after the L-shaped protective plate 5 finishes covering and protecting the pin 3, the L-shaped protective plate 5 and the auxiliary baffle 6 can work together to conduct heat and assist in heat dissipation for the entire device. The front end face of the auxiliary baffle 6 is coplanar with the front end face of the L-shaped protective plate 5, and the rear end face of the auxiliary baffle 6 is coplanar with the rear end face of the auxiliary baffle 6 to avoid structural interference. The side structure of the L-shaped protective plate 5 away from the winding 1 is set as a semi-cylindrical structure to avoid scratches. There is a clearance between the front and rear end surfaces of the L-shaped protective plate 5 and the corresponding bearing seats to avoid excessive friction between adjacent structures and improve the smoothness of the L-shaped protective plate 5's reciprocating flipping process. The surface of the L-shaped protective plate 5 has several through-hole strip grooves 8. When the L-shaped protective plate 5 is not flipped, the strip grooves 8 and the top space of the protective shell form a hot and cold air exchange channel, thus expanding another heat dissipation technology and ensuring the reliability of the entire device during use.

[0030] When using the anti-interference high-frequency transformer formed by winding 1, core clamp 2 and multiple pins 3 and the corresponding structure, disassemble 75 and reset the two composite straight tooth plates 71 and L-shaped protective plates 5.

[0031] Then, during the heat generation process of the anti-interference high-frequency transformer, multiple auxiliary baffles 6 and L-shaped protective plates 5 can be used to further conduct heat dissipation of the heat transmitted by the whole device. At the same time, the hot and cold air exchange channels formed by multiple strip slots 8 and the top of the iron core clamp plate 2 can also assist the whole device in heat dissipation by hot and cold air convection.
