[0002] Compared with ordinary diodes, Schottky diodes have a lower voltage drop when current flows through them, thereby improving system efficiency and recovering quickly. Wires can be connected as input and output options when switching the power supply. However, ordinary Schottky diodes only have round holes welded on the cathode sheet inside, and the connected copper wire harnesses are often directly entangled with them without reinforcement tools. If they cannot be locked and fixed, the thin copper wires can easily fall out of the round holes, causing problems such as circuit interruption.

[0003] Now, a new type of high withstand voltage Schottky diode is proposed to solve the above problems. Utility Model Content

[0010] Preferably, the front shell and the rear shell are in the same plane, and the plug block is embedded in the inside of the plug hole.

[0026] Embodiment 2: The four corners of the front of the rear shell 25 are all provided with plug holes 26, and the guide rod 21 is welded to the rear of the inner side of the plug hole 26, and the four corners of the rear of the front shell 1 are all welded with plug blocks 22, and the plug block 22 is provided with a cavity 23 inside, the guide rod 21 is embedded in the cavity 23, and a stopper 24 is welded in front of the guide rod 21. A second spring 20 is welded between the inner side of the plug hole 26 and the plug block 22, and the stopper 24 is embedded in the cavity 23.

[0027] Specifically, Figure 1 and Figure 3 As shown, the front casing 1 and the rear casing 25 are forcibly pushed apart, the former is embedded in the insertion hole 26 by means of the plug 22, and is connected to the inner side of the insertion hole 26 by the second spring 20.
