CABLE WITH FLEXIBLE HIGH PRESSURE EQUIPMENT ENCLOSURE

摘要

CABLE WITH FLEXIBLE HIGH PRESSURE EQUIPMENT ENCLOSURE A flexible, high pressure housing (12) (FIG. 5) is included in an equipment enclosure (11) between sections (10) of a signal communication cable. The housing includes an axially compressed length of corrugated tubing in which the corrugations have been collapsed against one another. Housing ends are sealed (25) to maintain a predetermined interior pressure in spite of variations in pressure outside the housing. Also included in the enclosure are structures (13) 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.
