[0002] A triode (bidirectional controllable high-voltage device) usually refers to a thyristor (SCR), also known as a silicon-controlled rectifier. It is a semiconductor device with bidirectional conduction properties and can control the switch of a high-voltage circuit. When testing a silicon triode (also known as a transistor), testers need to use high voltage to conduct a breakdown test on the triode to detect whether the performance of the triode is qualified.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1

[0030] Refer to Figure 3 、 Figure 4 This embodiment provides a bidirectional controllable high-voltage test mechanism for a silicon triode, including an equipment box 1, a bearing plate 2, a reset structure 3, a triode body 7, and a clamping structure 8. A bearing plate 2 is arranged inside the equipment box 1, and six groups of reset structures 3 are arranged on the lower surface of the bearing plate 2. The reset structure 3 facilitates the reset of the bearing plate 2. The reset structure 3 includes a telescopic tube 4, a telescopic rod 5, and a spring 6. The telescopic rod 5 is movably arranged inside the telescopic tube 4, and a spring 6 is arranged at the lower end of the telescopic rod 5. A triode body 7 is arranged above the bearing plate 2.

[0031] Among them, a threaded hole is provided on the outer surface of one end of the equipment box 1, two groups of sliding grooves are provided on the inner bottom of one end of the equipment box 1, a rubber pad 12 is fixedly connected to the inner wall of the other end of the equipment box 1, and one side of the rubber pad 12 away from the inner wall of the equipment box 1 fits on the outer surface of the triode body. The rubber pad 12 plays a role in protecting the triode body 7. A number of heat dissipation holes are respectively provided on the outer surfaces of both sides of the other end of the equipment box 1, a heat dissipation fan 13 is fixedly connected to the inner wall of one side of the other end of the equipment box 1, and the heat dissipation fan 13 is electrically connected to an external power supply. The bearing plate 2 is located between the heat dissipation holes on the outer surfaces of both sides of the other end of the equipment box 1. When the triode body 7 is subjected to a high-voltage discharge test, air enters from the heat dissipation holes on one side outer surface of the equipment box 1 and passes through the inside of the equipment box 1, and the heat inside the equipment box 1 is discharged from the heat dissipation holes on the other side outer surface of the equipment box 1. The heat dissipation fan 13 is started, and after the heat dissipation fan 13 is started, the air flow inside the equipment box 1 is accelerated, so that the temperature of the triode body 7 is reduced, preventing the triode body 7 from being damaged due to high temperature.

[0032] Among them, the lower end of the telescopic tube 4 is fixedly connected to the inner bottom of the equipment box 1, the lower end of the spring 6 is fixedly connected to the inner bottom of the telescopic tube 4, the lower end of the telescopic rod 5 is fixedly connected with a pressing piece 14, the lower surface of the pressing piece 14 is fixedly connected to the upper end of the spring 6, the upper end of the telescopic rod 5 passes through the upper end of the telescopic tube 4 and is fixedly connected to the upper surface of the bearing plate 2, a rubber pad 12 is fixedly connected to the upper surface of the bearing plate 2, and the lower surface of the triode body 7 fits on the upper surface of the rubber pad 12. The rubber pad 12 plays a role in protecting the triode body 7. Press the triode body 7, so that the triode body 7 presses the bearing plate 2 through the rubber pad 12, the bearing plate 2 presses the telescopic rod 5, the telescopic rod 5 enters the inside of the telescopic tube 4, and the telescopic rod 5 presses the spring 6 through the lower pressing piece 14 at the lower end. The spring 6 is compressed to generate an elastic force, so that the triode body 7 enters the inside of the equipment box 1, releasing the limit on the triode body 7. Under the elastic force of the spring 6, the telescopic rod 5 extends out of the sleeve, so that the bearing plate 2 rises, facilitating the triode body 7 to extend above the equipment box 1 and facilitating the taking of the triode body 7.

[0033] The working principle of this embodiment is as follows:

[0034] First, the operator places the triode body 7 on the upper surface of the rubber pad 12 on the upper surface of the carrier plate 2. The operator presses the triode body 7, causing the triode body 7 to squeeze the carrier plate 2 through the rubber pad 12. The carrier plate 2 squeezes the telescopic rod 5, and the telescopic rod 5 enters the inside of the telescopic tube 4. The telescopic rod 5 squeezes the spring 6 through the lower extrusion piece 14 at the lower end. The spring 6 generates elastic force under extrusion. After the triode body 7 enters the equipment box 1, the clamping structure 8 clamps and limits the triode body. When the triode body 7 is subjected to a high-voltage discharge test, air enters from the heat dissipation holes on the outer surface of one side of the equipment box 1 and passes through the inside of the equipment box 1, and discharges the heat inside the equipment box 1 from the heat dissipation holes on the outer surface of the other side of the equipment box 1. The operator starts the cooling fan 13. After the cooling fan 13 starts, it speeds up the air circulation inside the equipment box 1, reducing the temperature of the triode body 7 and preventing the triode body 7 from being damaged due to high temperature. When the high-voltage test of the triode body 7 is completed, the operator releases the limit of the clamping structure 8 on the triode body 7. Under the elastic force of the spring 6, the telescopic rod 5 extends out of the sleeve, causing the carrier plate 2 to rise, facilitating the triode body 7 to extend above the equipment box 1 for the operator to easily pick up the triode body 7.

[0035] Embodiment 2

[0036] Refer to Figure 1 、 Figure 2 and Figure 3 This embodiment is based on the previous embodiment. The difference from the previous embodiment is that a clamping structure 8 is provided on one side of the carrier plate 2. The clamping structure 8 facilitates clamping, fixing, and limiting the triode body 7. The clamping structure 8 includes a clamping plate 9, a pushing plate 10, and a threaded rod 11. A pushing plate 10 is provided on one side of the clamping plate 9, and a threaded rod 11 is provided on the side of the pushing plate 10 away from the clamping plate 9.

[0037] A rubber pad 12 is fixedly connected to the side of the clamping plate 9 away from the pushing plate 10. The rubber pad 12 plays a role in protecting the triode body 7, and the side of the rubber pad 12 away from the clamping plate 9 fits against the outer surface of the triode body.

[0038] One end of the pushing plate 10 is fixedly connected to one side of the clamping plate 9, and two sliding blocks 15 are fixedly connected to the lower surface of the end of the pushing plate 10 away from the clamping plate 9. The sliding blocks 15 play a role in assisting the sliding of the pushing plate 10.

[0039] Among them, two groups of sliding blocks 15 are respectively slidably connected to the inside of two groups of sliding grooves at the bottom of the device box 1. Through holes are provided on the side surfaces of the two groups of sliding blocks 15. Slide bars 17 are respectively slidably connected to the inside of the through holes on the side surfaces of the two groups of sliding blocks 15. Both ends of the two groups of slide bars 17 are respectively fixedly connected to the inner walls of the two ends of the two groups of sliding grooves at the bottom of the device box 1. The sliding block 15 can slide on the outer surface of the slide bar 17 through the through hole on the side surface, and the slide bar 17 can limit the sliding block 15 inside the sliding groove at the bottom of the device.

[0040] Among them, the threaded rod 11 is threadedly connected to the inside of the threaded hole on the outer surface of one end of the device box 1. One end of the threaded rod 11 is rotatably connected to the end of the push plate 10 away from the clamping plate 9. The other end of the threaded rod 11 extends to the outer surface of the device box 1. A runner 16 is fixedly connected to the end of the threaded rod 11 extending to the outer surface of the device box 1. The runner 16 facilitates the operator to hold and rotate.

[0041] The working principle of this embodiment is as follows:

[0042] The operator first places the triode body 7 between the rubber pads 12 on one end inside of the device box 1 and the rubber pad 12 on one side of the clamping plate 9. The operator holds and rotates the runner 16. When the runner 16 rotates, it drives the threaded rod 11 to rotate. When the threaded rod 11 rotates, it is threadedly connected to the threaded hole on the outer surface of one end of the device box 1, so that one end of the threaded rod 11 pushes the push plate 10 to move. The push plate 10 slides along the sliding groove at the inner bottom of the device box 1 through the sliding block 15 on the lower surface. The push plate 10 pushes the rubber pad 12 to fit against the outer surface of the triode body 7, so as to fix the triode body, which facilitates the operator to perform high-voltage discharge to conduct a high-voltage test on the triode body 7.
