Canon patent for lubricating body cap


The Canon patent describes a body cap that keeps the lens mount of a DSLR lubricated. To be honest I can’t grab the utility of this, except that it could concern the electric contacts (keeping them clean) . Since we get this patent literature translated by a machine, I am never sure the translated words are any helpful.
