Abstract: A zero insertion force connector, typically used for connecting a flexible printed circuit (FPC) or a flexible flat cable (FFC) to a printed circuit board, is made up of an insertion aperture formed on one side of a housing, a pressure plate insertion aperture formed on a different side of the housing, a pressure plate, and a sigmoid contact member. When the pressure plate is inserted into the pressure plate insertion aperture, a finger piece of the sigmoid contact member resiliently changes position, and a tongue piece of the sigmoid contact member makes electrical contact with an inserted FPC or FFC. Since the tongue piece of the sigmoid contact member is arranged so that the tongue piece does not come into contact with the FPC or FFC unless the pressure plate is inserted, there is no requirement to force the FPC or FFC into the insertion aperture.

Abstract: An electrical cord connector includes a strap which is adapted to be placed over an extension cord, the strap having a plurality of retaining slots which are designed to receive a tab from a retaining member secured to a receptacle, whereby the plug end of the extension cord may be inserted in and secured to the receptacle by the strap and tab assembly. The cord connector and retainer is equally well suited for securing the plug either to a standard wall receptacle or to a second extension cord.
