Abstract
An improved swivel connector for use in connecting one end of a flexible vacuum cleaner hose to the suction inlet of the canister portion of a canister vacuum cleaner. The hose is provided with electrical conductors and the swivel connector is mounted on the end of the hose and arranged to effect an automatic connection and disconnection of the electrical conductors of the hose to a power source in the canister as an incident of connection and disconnection, respectively, of the suction hose end to the suction inlet of the canister. The swivel connector includes a pigtail for effecting the connection between the relatively swivelable parts of the connector. Stops are provided for limiting the amount of swiveling permitted so as to prevent strain from being applied to the pigtail ends, while providing substantial permitted angle of swiveling, as desired.
