Vacuum cleaning apparatus

Abstract

Abstract ABSTRACT OF THE DISCLOSURE A vacuum cleaning apparatus is provided herein comprising a current-carrying vacuum hose provided with a hose connector at one end thereof which has a pigtail-free shielded electrical con- nector assembly which is installed and self locked in position af- ter assembly of the hose connector. This shield which is fixed to the support structure for shielding one of the electrical connectors is one having an axial length, measured substantially parallel to the longitudinal axis which is at least equal to the axial length of the second male electrical connector. The shield further has a roughly U-shaped cross section at least axial position thereof along its axial length. The shield and support structure are made of an electrically insulating polymeric material as a single piece. The electrical connector assembly including the shield, the support structure and the male electrical connectors comprise a single unit locked to the hose connector. Such pigtail-free shielded electrical connector assembly is particularly adapted to be directly connected with a female electrical connector in a housing assembly of a canister-type vacuum cleaner. This provides an economical cons- truction which is also of optimum safety due to its self-locking character and shielding of its protruding metal male electrical connector.
