Description

Technical Field

[0001] The utility model relates to the technical field of MOS tubes, in particular to a MOS tube structure with quick plug-in. Background Art

[0002] MOS tube is called Metal-Oxide-Semiconductor Field Effect Transistor, which is a field effect transistor that can be widely used in analog and digital circuits. It can be divided into enhancement MOS tube and depletion MOS tube according to its structure, and can be divided into N-channel and P-channel MOS tube according to the channel material.

[0003] MOS tubes can be fixed on PCB boards in many ways. The most commonly used method is welding, but in addition to welding, there are also many other methods: surface mounting, through-hole mounting, fixture fixing, adhesive, screw fixing, etc. The choice of fixing method depends on the application, power level, size, thermal management requirements and PCB layout of the MOS tube. In actual applications, multiple fixing methods may be used in combination according to specific circumstances.

[0004] However, in real life, there are some devices that require multiple MOS tubes to be plugged into a PCB board. However, in this case, simply using a manual installation method to install the MOS tubes on the PCB board one by one requires a certain amount of time and effort. In general, the more MOS tubes are installed, the more likely problems will occur during the installation process. In view of this, a MOS tube structure with quick plug-in is provided to overcome the above defects. Utility Model Content

[0025] As a further implementation scheme of the above technical scheme: first push blocks 2 are fixedly connected to both sides of the bottom of the first connecting member 1, and second push blocks 18 are fixedly connected to both sides of the bottom of the second connecting member 17. The number of the first push blocks 2 is two, and the number of the second push blocks 18 is two. This makes it convenient to control the opening and closing of the first connecting member 1 and the second connecting member 17 by the two push blocks, and facilitates people to install and disassemble the MOS tube clamped by the connecting members.

[0026] As a further implementation scheme of the above technical scheme: one side of the first push block 2 is fixedly connected to a fixed block 6, one side of the fixed block 6 is fixedly connected to a rotating rod 4, and the rotating rod 4 is rotatably connected to a cross bar 5, so that it is convenient to fix the cross bar 5 through the rotating rod 4, so that the cross bar 5 can rotate on the rotating rod 4.

[0027] As a further implementation scheme of the above technical scheme: a slider 13 is fixedly connected to one side of the cross bar 5, and the number of the sliders 13 is two. A slide groove 12 is respectively provided on one side of the first push block 2 and the second push block 18. The cross section of the slide groove 12 is semi-elliptical, so that it is convenient to drive the two sliders 13 arranged on one side of the cross bar 5 to slide in the slide groove 12 by rotating the cross bar 5, and drive the first connecting member 1 and the second connecting member 17 to separate.

[0030] Working principle:

[0031] When the utility model is used, because the fixed block 6 is fixed to one side of the first push block 2, and one side of the fixed block 6 is fixedly connected to the rotating rod 4, and the rotating rod 4 is rotatably connected to the cross bar 5, the cross bar 5 is rotated at this time to rotate the cross bar 5, and while the cross bar 5 rotates, the two sliders 13 fixed on one side of the cross bar 5 are driven to slide in the slide grooves 12 opened on the one side of the first push block 2 and the second push block 18. Because the two slide grooves 12 opened on the one side of the first push block 2 and the second push block 18 are combined into an ellipse, when the slider 13 moves along the slide groove 12 from the upper and lower sides of the slide groove 12, the slider 13 can slide in the slide groove 12. After the first push block 2 and the second push block 18 move to the middle position on the left and right sides of the slide groove 12, the first push block 2 and the second push block 18 will move to both sides while the slider 13 rotates, so that the first push block 2 and the second push block 18 can be separated. When the first push block 2 and the second push block 18 are separated, the connecting rod 11 arranged on the other side of the first push block 2 will slide in the connecting hole 14 opened on one side of the second push block 18, and limit the first push block 2 and the second push block 18 to prevent the position of the first push block 2 and the second push block 18 from shifting. When the first push block 2 and the second push block 18 are separated, the bottom The first connecting piece 1 and the second connecting piece 17 fixedly connected to the top of the first push block 2 and the second push block 18 at the ends are separated synchronously. At this time, the MOS tube body 7 to be installed is placed inside the first connecting piece 1 and the second connecting piece 17, so that one side of the MOS tube body 7 is in contact with one side of the first heat conducting plate 9, and the fixing hole 8 opened on the top of the MOS tube is aligned with the block 10 opened on one side of the first heat conducting plate 9, so that the block 10 slides to the inside of the fixing hole 8, and the cross bar 5 is rotated to turn the slider 13 back to its original position, and the first connecting piece 1 and the second connecting piece are connected. The member 17 is closed under the rebound effect of the return spring 15 fixed to one end of the connecting rod 11, and drives one side of the second heat conducting plate 16 to contact with the other side of the MOS tube. The first heat conducting plate 9 and the second heat conducting plate 16 contacting with both sides of the MOS tube body 7 guide the heat generated by the MOS tube body 7 during operation through the heat sink 3 provided on the other side thereof, and then the guided heat is dissipated into the air through the heat sink 3, so as to avoid the MOS tube body 7 from being overheated during operation, thereby affecting the performance of the MOS tube body 7 and reducing the service life of the MOS tube.

[0032] In the present invention, the components such as the return spring 15, the first heat conducting plate 9, the heat sink 3, etc. are all existing and practical, and their working principles are consistent with similar products on the market, so they will not be described in detail here.
