cause |
The lead wire breaks through the insulating plate pasted on the noise suppression
shield plate and the primary and secondary sides come into contact. |

consideration |
Safety standards have regulations regarding AC adapter drop tests
and case thickness. However, there are no clear regulations regarding strength. It is left to the judgment of the manufacturer. The AC adapter may be stepped on by the user or placed on top of it. Shouldn't we have assumed a case that would be handled roughly? |
important point |
Were the material and thickness of the insulating plate attached
to the shield plate appropriate? Safety standards specify the thickness of the primary-secondary insulator. Was the case strength appropriate? |
best way |
Ribs and bosses on the case increase strength. Change the material and thickness of the insulation plate to an appropriate one. |
