Abstract
Abstract A canister vacuum cleaner having electrical conductors extending from electrical circuitry in the canister through the connection of the suction hose thereto through electrical conductors embodied in the suction hose to electrical apparatus associated with a nozzle, such as a brush motor therein. The electrical connection between the hose end and the canister is provided by a first electrical connector mounted to the hose end, and a second electrical connector mounted to the base portion of the canister housing. Both the hose suction connector and the first electrical connector at the hose end are freely installable through a suction inlet passage formed in the cover and are then connected to a source of suction and a second electrical connector mounted in the base. Forces developed in connecting and disconnecting the first electrical connector from the second electrical connector are accommodated by the base portion of the canister housing by virtue of the mounting of the second electrical connector thereto in alignment with the suction inlet opening, whereby automatic connection of the electrical connectors is effected as an incident of the installation of the suction hose connector in the suction inlet opening and there is no need for electrical circuitry in the cover. The cover is relatively lightweight and inexpensive as a result of the improved arrangement and is easily removable since there is no need to break an electrical connection.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
140 words
In a vacuum cleaner having a canister including a base defining a suction space and a cover removably closing said space, a suction hose having an end defining a suction connector, means formed on said cover defining a suction inlet opening for receiving the hose end connector to conduct dirt laden air to said space, and electrical conductor means carried by the suction hose and having a first electrical connector associated with said suction connector, the improvement comprising: a second electrical connector complementary to said first electrical connector mounted to said base to have electrical connected association with said first electrical connector as an incident of said suction connector being installed in said inlet opening, said cover being substantially free of forces developed in effecting electrical connection and disconnection of said first electrical connector relative to said second electrical connector.
Claim 2
Dependent Claim
140 words
In a vacuum cleaner having a canister including a base defining a suction space and a cover removably closing said space, a suction hose having an end defining a suction connector, means formed on said cover defining a suction inlet opening for receiving the hose end connector to conduct dirt laden air to said space, and electrical conductor means carried by the suction hose and having a first electrical connector associated with said suction connector, the improvement comprising: a second electrical connector complementary to said first electrical connector mounted to said base to have electrical connected association with said first electrical connector as an incident of said suction connector being installed in said inlet opening, said cover being substantially free of forces developed in effecting electrical connection and disconnection of said first electrical connector relative to said second electrical connector.
