ABSTRACT:
A flexible, high pressure housing is included in an equipment encloure between sections of a signal communication cable. The housing includes an axially compressed length of corrugated tubing in which the corrugations have been collapsed against the another. Housing ends are sealed to maintain a predetermined interior pressure in spite of variations in pressure outside the housing. Also included in the enclosure are structures for applying the outside pressure to the housing so that it is resiliently transversely flexible in response to similar outside and inside pressures but rigid in response to outside pressures much greater than inside pressures.
