Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof detection of diode aluminum shells, in particular to an explosion-proof effect detection device. Background Art

[0002] The diode is an electronic device made of semiconductor materials. It is a structure consisting of a PN junction plus corresponding electrode leads and a tube shell (aluminum shell) package. The diode has unidirectional conductivity. When it is turned on, the current flows from the anode through the tube to the cathode. The explosion-proof performance of the diode aluminum shell is related to the stability of the diode's operation.

[0003] Explosion-proof is the process of resisting a certain force impact while maintaining its own functions as much as possible. Most of the diode aluminum shells need to undergo multiple explosion-proof tests before they can be subsequently assembled and put into use. Otherwise, if they are damaged by external forces during such processes, it will be difficult to preserve the integrity of the internal diode aluminum shell;

During the explosion-proof test, although the current situation of fixed explosion-proof components is broken, the detection plate filled with diode aluminum shells needs to be placed in the detection equipment as a whole during the explosion-proof detection of the diode aluminum shell. The gap between the two cannot be quickly adjusted according to the explosion intensity of the explosion point below, and there is uneven force in the explosion-proof detection of the diode aluminum shell.
