[0028] Reference Figure 1-5 As shown, this utility model provides a technical solution: a highly stable digital transistor, including a transistor body 1 and a mounting base 3, with three pins 2 fixedly connected to the surface of the transistor body 1.
[0029] The following is a detailed explanation of its overall setup and function.
[0030] In this implementation scheme: two connecting plates 5 are fixedly connected to the surface of the mounting base 3, and a limiting frame 8 is slidably connected inside the connecting plates 5. By setting an elastic pad 6, wear between the transistor body 1 and the mounting base 3 can be avoided, further improving the safety of using the transistor body 1. By setting the above structure, a detachable transistor body 1 structure is provided, which not only improves the stability of using the transistor body 1, but also allows for flexible disassembly and replacement of the transistor body 1, improving the installation and use effect of the digital transistor. A positioning block 4 is fixedly connected to the lower surface of the transistor body 1, and a positioning hole 7 is opened on the surface of the mounting base 3. The size of the positioning hole 7 matches the size of the positioning block 4. Aligning the positioning block 4 on the transistor body 1 with the positioning hole 7 allows for positioning of the transistor body 1. A guide block 13, which has a trapezoidal structure, is fixedly connected to the lower end of the positioning block 4. By setting the guide block 13 with a trapezoidal structure, the efficiency of inserting the positioning block 4 into the positioning hole 7 is improved. A spring piece 9 is fixedly connected to the inner side of the limiting frame 8. The limiting frame 8 will move under the elastic force of the spring piece 9, thereby realizing the locking operation of the transistor body 1 at the upper position.
[0031] Specifically, a rotating rod 10 is rotatably connected inside the limiting frame 8, and a support foot 11 is fixedly connected to one end of the rotating rod 10. The support foot 11 is supported on the surface of the connecting plate 5, providing temporary support for the limiting frame 8 after it is pulled out. A rotating block 12 is fixedly connected to the other end of the rotating rod 10. Rotating the rotating block 12 causes the rotating rod 10 to twist. An elastic pad 6 is glued to the surface of the mounting base 3. By setting the elastic pad 6, wear between the transistor body 1 and the mounting base 3 can be avoided, further improving the safety of using the transistor body 1.
[0032] Working principle: When installing the digital transistor, the mounting base 3 is first fixed to the circuit board using glue or other connection methods. After fixing the mounting base 3, the two limiting frames 8 are pulled to the side furthest from each other. The rotating block 12 is rotated, which drives the rotating rod 10 to twist. This drives the support foot 11 to rotate, supporting the support foot 11 on the surface of the connecting plate 5. This provides temporary support for the pulled-out limiting frames 8. When installing the transistor body 1, the positioning block 4 on the transistor body 1 can be aligned with the positioning hole 7. By setting the guide block 13 with a ladder structure, the efficiency of the positioning block 4 being inserted into the positioning hole 7 is improved, thus achieving the positioning of the transistor body 1. Then, the rotation is performed again. The rotating block 12 rotates the support foot 11 off the surface of the connecting plate 5. The limiting frame 8 moves under the elastic force of the spring piece 9, thereby locking the transistor body 1 on the upper side and achieving stable installation of the transistor body 1. This improves the stability of using the transistor body 1 on the circuit board. By setting the elastic pad 6, wear between the transistor body 1 and the mounting base 3 can be avoided, further improving the safety of using the transistor body 1. By setting the above structure, a detachable transistor body 1 structure is set, which not only improves the stability of using the transistor body 1, but also enables flexible disassembly and replacement of the transistor body 1, improving the installation and use effect of digital transistors.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
