[0002] An electronic transformer is a power conversion device that uses electronic devices (such as transistors, power MOSFETs, etc.) to convert input AC power into power output of different voltages, currents or frequencies.
[0003] In the current existing technology, the electronic transformer is an important component of the power adapter. The coil of the voltage transformer is welded on the circuit board by pins, and the pins play a role of fixing and supporting. The pins on both sides of the electronic transformer coil are first bent and then trimmed to make the length of the pins neat, and then they are welded and fixed to the circuit board by welding.
[0004] In the current prior art, electronic transformers are widely used in electric vehicle chargers, which change the voltage, current and frequency of the input power supply to adjust the output power supply. However, electric vehicle chargers often bump and fall, and the coil of the electronic transformer is only fixed by pin welding, which has a poor fixing effect and can easily cause the coil of the electronic transformer to shift and cause the pin to become unsoldered. Therefore, an electronic transformer protection device is proposed to address the above problems. Utility Model Content

[0023] Specific examples are given below.
[0024] See also Figure 1-5As shown, an electronic transformer protection device comprises a base 11; a fixing frame 13 is provided on the top of the base 11; a card slot is provided on the top of the fixing frame 13; a pair of card plates 12 are fixedly connected to the top side of the base 11; fixing bolts 14 are provided on both sides of the base 11; a plurality of guide holes 32 are provided on both sides of the base 11; through holes are provided on both sides of the bottom of the fixing frame 13; a stud 15 is threadedly connected to the bottom end of the fixing bolt 14; when in use, the bottom plate is placed at the bottom of the electronic transformer coil core, clamped by the card plates 12 on both sides, the base 11 is padded on the circuit board, and the electronic transformer coil The pins are located on both sides of the base 11; corresponding mounting holes are opened on the circuit board, and the studs 15 are located at the bottom of the mounting holes (the back of the circuit board). Then the fixing frame 13 is clamped on the electronic transformer coil, and then the bolts are passed through the through holes and guide holes 32 to connect with the studs 15, and then they are fixed by bolts. This setting can improve the fixing effect of the electronic transformer coil, thereby reducing the situation where the coil of the electric vehicle charger shakes and causes the pins to become unsoldered when it falls, especially for fixing the coil of a high-power charger. The overall mass of the coil of a high-power charger is larger, and the pins are more likely to become unsoldered when they fall.
[0025] Further, such as Figure 3-4 As shown, both sides of the fixing frame 13 are provided with sliding grooves; vertical rods 21 are slidably connected in the sliding grooves; through grooves are provided at the bottom of the fixing frame 13 and at positions corresponding to the vertical rods 21; both sides of the vertical rod 21 are hinged with connecting rods 22; the ends of the connecting rods 22 are hinged with cross rods 23; the cross rod 23 is slidably connected to the sliding grooves; one end of the cross rod 23 away from the connecting rod 22 is fixedly connected with a fixing piece 24; when in use, in the initial state, the fixing pieces 24 on both sides are opened, which can facilitate the fixing piece 24 to be put on the electronic transformer coil. After the fixing frame 13 is bolted, its extrusion will push the vertical rod 21 to move upward, and then the cross rods 23 on both sides are pulled by the connecting rod 22 to move, so that the fixing piece 24 is closed, so that the electronic transformer coil can be fixed from both sides, thereby improving the fixing effect and reducing its shaking.
[0026] Further, such as Figure 2 As shown, a vertical cylinder 31 is fixedly connected to the inside of the through hole; the bottom of the vertical cylinder 31 is inserted into the guide hole 32 and slidably connected thereto; the fixing bolt 14 passes through the vertical cylinder 31; when in use, when the fixing frame 13 is connected to the base 11, the vertical cylinder 31 will be inserted into the guide hole 32 of the base 11, so as to connect and position the fixing frame 13 and the base 11, and then the staff only needs to operate the fixing bolts 14 and the studs 15 to tighten and fix them, so that it can be used conveniently.
[0027] Further, such as Figure 5As shown, a through groove 41 is provided inside the card plate 12; a spring piece 42 is fixedly connected to the inner wall of the through groove 41; the spring piece 42 is made of plastic material; when in use, the base 11 is stuck at the bottom of the electronic transformer coil, and it relies on the plastic spring piece 42 at the bottom to clamp the bottom of the electronic transformer coil core, which can play a certain fixing role and prevent it from falling off.
[0028] Further, such as Figure 1-2 As shown, a pair of elastic pads 5 are fixedly connected to one side of the fixing plate 24 close to the fixing frame 13; the elastic pad 5 is made of silicone material; a rubber gasket 6 is arranged on the top of the stud 15; the fixing bolt 14 passes through the rubber gasket 6. When in use, the elastic pad 5 is used to play a protective role, so that the fixing plate 24 and the winding of the electronic transformer coil are in elastic contact, thereby reducing the excessive extrusion thereof. The elastic pad 5 is used to pad the front and back of the circuit board, which can play a protective role, thereby reducing the damage to the circuit board caused by over-tightening of the fixing bolt 14, and when shaking occurs, it can play a certain role in buffering and shock absorption, thereby reducing the damage to the bottom circuit board.
[0029] Working principle: when in use, the bottom plate is placed at the bottom of the core of the electronic transformer coil, clamped by the clamping plates 12 on both sides, the base 11 is padded on the circuit board, and the pins of the electronic transformer coil are located on both sides of the base 11; a corresponding mounting hole is opened on the circuit board, and the stud 15 is located at the bottom of the mounting hole (the back of the circuit board), and then the fixing frame 13 is clamped on the electronic transformer coil, and then the bolts are passed through the through holes and guide holes 32 to connect with the stud 15, and then it is fixed by bolts. This setting can improve the fixing effect of the electronic transformer coil, thereby reducing the situation where the coil shakes and the pins are desoldered when the electric vehicle charger falls, especially for fixing the coil of a high-power charger. The overall mass of the coil of a high-power charger is larger, and the pins are more likely to be desoldered when they fall. In the initial state, the fixing plates 24 on both sides are opened, which can easily put the fixing plates 24 on the electronic transformer coil. After the fixing frame 13 is fixed with bolts, its extrusion will push the vertical rod 21 upward, and then pull the cross bars 23 on both sides to move through the connecting rod 22, so that the fixing plate 24 can be moved. When the fixing frame 13 is connected to the base 11, the vertical tube 31 thereof will be inserted into the guide hole 32 of the base 11, so as to connect and position the fixing frame 13 and the base 11. After that, the staff only needs to operate the fixing bolts 14 and the studs 15 to tighten and fix them, so that it can be convenient to use. When the base 11 is stuck at the bottom of the electronic transformer coil, it relies on the plastic spring sheet 42 at the bottom, which can clamp the bottom of the iron core of the electronic transformer coil, which can play a certain fixing role and make it not easy to fall off. When in use, the elastic pad 5 is used to play a protective role, so that the fixing sheet 24 and the winding of the electronic transformer coil are in elastic contact, thereby reducing the situation of excessive extrusion. The elastic pad 5 is used to pad the front and back of the circuit board, which can play a protective role, thereby reducing the damage to the circuit board caused by over-tightening of the fixing bolts 14, and when shaking occurs, it can play a certain buffering and shock-absorbing role, reducing the damage to the bottom circuit board.
