Abstract
A plug retainer for use in a vacuum cleaner having a handle removably connected to a wand. The plug retainer is arranged to effectively preclude discharge of static electricity from the dirty suction air to the electrical conductors and interconnected plugs so as to avoid spurious operation of electrostatic discharge sensitive control structure of the vacuum cleaner, which may include microprocessor control elements. The plug retainer structure includes a locking tongue and an integral static shield extending over a substantial area between the connected male and female plugs of the control wiring.
