Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a diode and transistor packaging structure, including a base plate 1, a fixing groove 2 is provided inside the base plate 1, a collector plate 3 is fixedly connected to the inside of the fixing groove 2 by threads, a collector terminal 5 is fixedly connected to the upper end of the collector plate 3, a positioning post 6 is fixedly connected to the upper end of the fixing groove 2, a transmitter terminal 4 is fixedly connected to the lower end of the collector plate 3, and the same positioning post 6 is fixedly connected to the lower end of the fixing groove 2. The collector terminal 5 and the transmitter terminal 4 are both sleeved inside the positioning post 6, and a sealing cover 7 is covered on the upper end of the base plate 1.

[0018] In this embodiment, the collector plate 3 can be fixed by the fixing groove 2 opened in the base plate 1. At the same time, the positioning posts 6 set at the upper and lower ends of the fixing groove 2 can be used to position and limit the collector end 5 and the transmitter end 4. Then, the sealing cover 7 is closed to fix the collector plate 3, the transmitter end 4 and the collector end 5 as a whole. This design adopts the cover-close method for encapsulation, which is convenient for disassembly, inspection and maintenance. At the same time, the positioning component can be set to achieve good positioning and accurate installation, and can also make the overall fixing effect better and prevent it from falling off.

[0019] Specifically, the surface of the sealed cover 7 is fixedly connected to a heat dissipation device 9 by a fixing screw 10.

[0020] In this embodiment, the heat dissipation device 9 can dissipate heat from the heat collection area 3, preventing excessive temperature from affecting its service life.

[0021] Specifically, the heat dissipation device 9 includes a fixing plate 11, a heat-conducting plate 12, and heat dissipation fins 13.

At the same time, the heat dissipation fins 13 dissipate heat from the heat-conducting plate 12, so that the heat collection plate 3 can dissipate heat quickly. This design can dissipate heat quickly, thereby effectively avoiding excessive internal temperature and providing good protection.
