Abstract
A female electrical connector which has a cross section distinguished by a deep keyway allowing it to be accepted by a complementarily shaped appliance receptacle having a discriminator blade which interfits with the keyway but which rejects other connector arrangements. The disclosed connector discourages possibly unsafe consumer practices in cord set use while affording a degree of manufacturing standardization with other connector and receptacle arrangements.
