Description

Technical Field

[0001] This utility model relates to the field of MOSFET technology, specifically a protection device for multiple MOSFETs. Background Technology

[0002] MOSFETs are metal-oxide-semiconductor field-effect transistors, also known as metal insulators. During processing and transportation, they are easily damaged by compression and bending, which affects their normal use later. Therefore, protective devices are used to store them.

[0003] However, existing protection devices still have the following technical problems in use:

[0004] In existing protection devices, after storing the MOSFET, the MOSFET is prone to displacement inside the protection device, which can cause wear and tear on the MOSFET. Furthermore, when it is necessary to remove the MOSFET from inside the protection device, it is inconvenient to remove it due to its small size.

[0005] Therefore, a protection device for multiple MOS transistors is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a protection device for multiple MOSFETs to solve the problems mentioned in the background art.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A protection device for multiple MOSFETs includes a protection box 1. Limiting blocks 2 are fixed to the left and right ends of the inner wall of the protection box 1. Limiting rods 3 are fixed to the lower sides of the two limiting blocks 2. The lower ends of the two limiting rods 3 are fixedly connected to the lower end of the inner wall of the protection box 1. A placement plate 4 is slidably connected to the outside of the two limiting rods 3. A first spring 5 is sleeved on the outside of the limiting rods 3. The two first springs 5 ​​are tension springs that apply an upward tension to the placement plate 4. The lower end of the first spring 5 is fixedly connected to the upper side of the placement plate 4, and the upper end of the first spring 5 is fixedly connected to the lower side of the limiting block 2.

[0027] The upper side of the placement plate 4 is provided with evenly arranged placement slots. The left and right ends of the inner wall of the placement slot are fixed with clamping mechanisms. The bottom of the placement slot is provided with an insertion hole. The MOS transistor 6 is inserted into the placement slot. The left and right width of the placement slot is much larger than the width of the MOS transistor 6, so that the placement slot is suitable for different models of MOS transistor 6.

[0028] The MOSFET 6 has a fixing mechanism inside. The upper end of the protective box 1 is fitted with a cover 7. The side wall of the cover 7 is provided with a symmetrical pressing mechanism. The fixing mechanism is used to limit and fix the MOSFET 6 to the left and right.

[0029] The protective box 1 has threaded mounting bolts on the upper left and right sides. The cover 7 is fixedly connected to the protective box 1 by the mounting bolts. The mounting bolts are used to connect and fix the protective box 1 and the cover 7.

[0030] A protective layer 8 is fixed to the lower end of the inner wall of the placement slot. The protective layer 8 is used to protect the bottom side of the MOS transistor 6 to avoid wear. The side wall of the protective layer 8 is provided with a hole that fits the MOS transistor 6, so that the MOS transistor 6 can be inserted.

[0031] The clamping mechanism includes a fixing block 9, which is fixedly connected to the inner wall of the placement groove. A slider 10 is slidably connected inside the fixing block 9. A second spring 11 is fixed to the side wall of the slider 10. The other end of the second spring 11 is fixedly connected to the inner wall of the fixing block 9. A rubber extrusion block 12 is fixed to the side of the slider 10 away from the second spring 11. The other side of the rubber extrusion block 12 contacts the side wall of the MOS transistor 6. The two second springs 11 drive the slider 10 on the side wall to move, and the slider 10 drives the rubber extrusion block 12 on the side wall to move. The two rubber extrusion blocks 12 work together to clamp and limit the MOS transistor 6 from left to right.

[0032] The fixing mechanism includes a crossbar 13 that passes through the MOS transistor 6. The left and right ends of the crossbar 13 are threaded with connecting bolts 14. The lower ends of the two connecting bolts 14 are threaded to the upper side of the placement plate 4. The fixing mechanism is used to limit the evenly arranged multiple MOS transistors 6, thereby ensuring that they do not move up and down.

[0033] The pressing mechanism includes a fixing rod 15, which is fixedly connected to the lower side of the cover 7. An arc-shaped plate 16 is fixed to the lower end of the fixing rod 15. The lower side of the arc-shaped plate 16 contacts the upper side of the crossbar 13. When the cover 7 is fixed to the upper end of the protective box 1, the fixing rod 15 and the arc-shaped plate 16 will press against the upper end of the crossbar 13, thereby causing the lower placement plate 4 to move down. When the cover 7 is removed, the placement plate 4 will move upward under the pulling force of the first spring 5, thereby causing the multiple MOS transistors 6 inside to move to the upper end of the protective box 1, making it convenient to quickly remove the MOS transistors 6.

[0034] Working principle:

[0035] When it is necessary to place the MOS transistor 6 inside the protective box 1, simply insert the MOS transistor 6 into the placement slot and clamp and fix it using the clamping mechanism. Then, pass the crossbar 13 through the inside of the MOS transistor 6 and fix the crossbar 13 to the placement plate 4 using the connecting bolt 14 to limit the position of the MOS transistor 6 and prevent it from moving and causing friction damage.

[0036] When it is necessary to remove the MOSFET 6, remove the mounting bolts, open the upper cover 7, release the pressure of the fixing rod 15 and the arc plate 16 on the crossbar 13, and the placement plate 4 moves upward under the tension of the first spring 5, thereby causing multiple MOSFETs 6 to move upward and to the upper end of the protective box 1, disassemble the crossbar 13 and take out the MOSFET 6.
