Disclosed is a vacuum housing for a magnetic resonance apparatus having a
recess for leading through lead wires to elements located inside the
vacuum housing, and a first lead-through bushing module. The first
lead-through bushing module is provided with a first closing plate which
is configured so as to vacuum-tightly seal the recess along with a second
closing plate. The first bushing module is also provided with a first
structural component that is to be at least partially led through the
recess during assembly of the lead-through bushing module and whose size
defines a minimum size of the recess, which is greater than the size of
the first closing plate.
