Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic device technology, and in particular to a highly drop-resistant integral molded inductor. Background Technology
[0002] Industries using high-power toroidal wound inductors for fixing include: frequency converter power supply industry, UV curing power supply industry, induction heater industry, etc. This high-power toroidal wound inductor fixing device has advantages such as low cost, rapid heat dissipation, firm fixing, strong drop resistance and vibration resistance, and has a wide range of applications.
[0003] Currently, most toroidal wire-wound inductors are directly fixed to the PCB board by soldering the inductor leads. Since toroidal wire-wound inductors have a certain mass, when the toroidal wire-wound inductor is soldered to the PCB board with only two leads, if the PCB board is dropped and vibrates, causing the inductor to vibrate, the inductor's two leads may bend and break, easily causing the inductor to detach. This can lead to short circuits and open circuits in the inductor coil, affecting the normal operation of the circuit, increasing the failure rate of the inductor, and reducing its lifespan. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a high-drop-resistant integral molded inductor. This inductor can solve the problem that when the PCB board is dropped and vibrates, causing the inductor to vibrate, the inductor's two pins to bend and break, which can easily cause the inductor to fall off. This can lead to short circuits and open circuits in the inductor coil, affecting the normal operation of the circuit, increasing the failure rate of the inductor, and reducing its service life.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-drop-resistant integral molded inductor, comprising a PCB mounting plate and an inductor fixing device; the inductor is fixedly mounted on the top of the PCB mounting plate, and two pins are fixedly connected to the bottom of the inductor; two mounting slots are opened on the top of the PCB mounting plate, located on the left and right sides of the two pins, and mounting blocks are fixedly mounted inside the two mounting slots; the inductor fixing device includes a lateral support plate, two fixing blocks, and a triangular reinforcing support plate; the lower end of the lateral support plate is fixedly connected to the top of the mounting blocks, the surface of the lateral support plate is in contact with the surface of the inductor, and two fixing holes are opened on the upper end of the lateral support plate.
[0006] Preferably, the lower ends of both pins are soldered to the surface of the PCB mounting plate.
[0007] Preferably, each of the two mounting blocks has two bolts installed inside.
[0008] Preferably, the bottom of the PCB mounting plate has four threaded slots, and the lower ends of the four bolts are threaded into the four threaded slots respectively.
[0009] Preferably, both fixing blocks are fixedly connected to the surface of the inductor, and the two fixing blocks are slidably engaged inside the two fixing holes.
[0010] Preferably, the triangular reinforcing support plate is fixedly connected to the surface of the lateral support plate, and the lower end of the triangular reinforcing support plate is fixedly connected to the top of the mounting block.
[0011] Preferably, the two mounting blocks have the same structure.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This high-drop-resistant, one-piece molded inductor prevents vibration when the PCB mounting board is dropped and vibrates, as the four fixing blocks are locked inside the four fixing holes and cannot vibrate up and down. This ensures the stability of the inductor's fixed mounting on the PCB surface, preventing the two leads from bending or breaking, and preventing the inductor from falling off due to vibration. This also avoids short circuits and open circuits in the inductor coil, ensuring normal circuit operation, enhancing the inductor's drop resistance, reducing the inductor's failure rate, and extending its service life.

[0024] Please see Figure 1-4This utility model provides a technical solution: a high-drop-resistant integral molded inductor, including a PCB mounting plate 1 and an inductor fixing device. An inductor 2 is fixedly mounted on the top of the PCB mounting plate 1, and two pins 3 are fixedly connected to the bottom of the inductor 2. The lower ends of the two pins 3 are soldered to the surface of the PCB mounting plate 1. Two mounting slots 4 are formed on the top of the PCB mounting plate 1, located on the left and right sides of the two pins 3. Mounting blocks 5 are fixedly mounted inside each of the two mounting slots 4, and two bolts 6 are installed inside each of the two mounting blocks 5. Four threaded slots 7 are formed on the bottom of the PCB mounting plate 1, and the lower ends of the four bolts 6 are respectively... The threaded connection is inside the four threaded slots 7. The inductor fixing device includes a lateral support plate 8, two fixing blocks 10, and a triangular reinforcing support plate 11. The lower end of the lateral support plate 8 is fixedly connected to the top of the mounting block 5. The surface of the lateral support plate 8 is in contact with the surface of the inductor 2. Two fixing holes 9 are opened at the upper end of the lateral support plate 8. Both fixing blocks 10 are fixedly connected to the surface of the inductor 2. The two fixing blocks 10 are slidably engaged inside the two fixing holes 9. The triangular reinforcing support plate 11 is fixedly connected to the surface of the lateral support plate 8. The lower end of the triangular reinforcing support plate 11 is fixedly connected to the top of the mounting block 5. The two mounting blocks 5 have the same structure.
[0025] After the worker solders the inductor 2 to the top of the PCB mounting plate 1 using two pins 3, they then remove the side support plate 8 and move it so that the two fixing blocks 10 engage with the two fixing holes 9, and the bottom mounting block 5 slides into the mounting slot 4. Finally, the worker uses a wrench to rotate the bolt 6, so that the lower end of the bolt 6 engages with the threaded groove 7, thus fixing the mounting block 5 into the mounting slot 4 using the two bolts 6. The worker then fixes the other mounting block 5 into the other mounting slot 4 in the same way, thereby fixing the side support plate 8 onto the inductor 2. On the left side, the inductor 2 can be supported and fixed by the two side support plates 8. When the PCB mounting plate 1 is dropped and vibrates, causing the inductor 2 to vibrate, the four fixing blocks 10 are stuck inside the four fixing holes 9 and cannot vibrate up and down, thus preventing the inductor 2 from vibrating. This ensures the stability of the inductor 2 fixedly mounted on the surface of the PCB mounting plate 1, thereby preventing the two pins 3 from bending and breaking, preventing the inductor 2 from vibrating and falling off, and thus avoiding short circuits and open circuits in the inductor 2 coil. This ensures the normal operation of the circuit, enhances the drop resistance of the inductor 2, reduces the failure rate of the inductor 2, and extends the service life of the inductor 2.
[0026] During the process of supporting the inductor 2, the two lateral support plates 8 are supported by two triangular reinforcing support plates 11 on the surface of the two lateral support plates 8, which enhances the stability of the two lateral support plates 8 in supporting the inductor 2, ensures the stability of the connection between the lateral support plates 8 and the mounting block 5, and enhances the strength of the support device.

[0034] Threaded slots 7: Four slots are formed on the surface of the PCB mounting plate 1. The lower ends of the four bolts 6 are threaded into them for installation and fixation.
[0035] Lateral support plates 8: Two, fixedly connected to the top of the two mounting blocks 5, to support and fix the inductor 2 and ensure the stability of the inductor 2;
[0036] Fixed holes 9: Four, opened at the upper end of the two side support plates 8. The four fixed blocks 10 are inserted into the four fixed holes 9 to prevent the inductor 2 from vibrating up and down and to fix the vertical position of the inductor 2.
[0037] Fixed blocks 10: Four of them are fixedly connected to the left and right sides of the inductor 2 respectively, and are slidably locked inside the four fixed holes 9 to position the inductor 2 vertically.
