Self-sealing vacuum hose swivel fitting

摘要

A fitting (10) secures a vacuum hose (20) to a wand or tank of a vacuum cleaner. The hose is swivelably and pneumatically sealed within the fitting through use of a sealing surface (18) on the fitting in engagement with a flexible lip (28) at the end portion (24) of the vacuum hose. A ring (30) engageable with the fitting compresses the end portion in order to bias the flexible lip into engagement with the sealing surface. The electrical terminations including slip rings (144) are used to terminate a hose (120) with electrical conductors therein to cooperating electrical connections.
