I've noted a number of fuse holders that appear to be made of that same 
cheap thermal plastic people complain about in the mini din connectors.
Once hot the plastic softens, the spring pushes the fuse and the holder 
gets reshaped.  The same is very common with the cigarette plugs we find 
of some portable equipment and chargers.
