Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage diodes, in particular to a detection mechanism for batch testing of high-voltage diodes. Background Art

[0002] A high-voltage diode is a silicon crystal diode that conducts only under high voltage. It is generally used in series with a large capacitor. When power is turned on, the capacitor charges slowly. When the trigger voltage of the high-voltage trigger diode is reached, it turns on instantly. Then, after a switch in the start-up circuit, the capacitor discharges. If the voltage value is not enough to turn it on, it returns to a high-impedance state. When the capacitor is charged to the set value, the cycle is triggered.

[0003] When high-voltage diodes are shipped out of the factory, their functions and performances need to be verified. In the prior art, batch verification and testing are not possible. In view of this, we propose a detection mechanism for batch testing of high-voltage diodes. Utility Model Content

[0009] Preferably, an upper pressure plate for limiting the high-voltage diode is provided on the top of the lower test plate, and a through hole is opened on the top of the upper pressure plate to accommodate the upper part of the high-voltage diode, so that the bottom of the upper pressure plate fits with the lower test plate, and the upper pressure plate is in a cross shape to fit the four terminals.

[0010] Preferably, limiting mechanisms are provided on both sides of the upper pressing plate to limit the movement of the upper pressing plate;

[0012] Preferably, second handles are connected to both sides of the top of the bottom plate for taking and placing the detection mechanism, because during the testing process, the detection mechanism needs to be completely immersed in insulating oil for testing.

[0013] Preferably, a first handle is provided on the top of the upper pressing plate, which is inclined at forty-five degrees and is used to move the upper pressing plate to limit the high-voltage diode.
