Description

Technical Field

[0001] The utility model relates to the technical field of MOS tubes, in particular to a protection device for multiple MOS tubes. Background Art

[0002] MOS tube is a metal, oxide, semiconductor field effect transistor, or metal-insulator, semiconductor. In most cases, the two regions are the same, and even if the two ends are swapped, it will not affect the performance of the device. Such a device is considered to be symmetrical. It not only has a simple structure but also is easy to operate.

[0003] When the existing protection device for multiple MOS tubes falls during use, the pins on the MOS tubes are prone to friction with the protection device. Since the pins are relatively fragile, they are easily bent, making it difficult to effectively protect the pins on the MOS tubes. In addition, the existing protection device is inconvenient when the MOS tube needs to be taken out, and it is easy to cause the MOS tube to fall when it is taken out, which reduces the practicability of the device and is not conducive to the normal use of the device.

[0004] Therefore, it is necessary to provide a protection device for multiple MOS tubes to solve the above technical problems. Utility Model Content
