ABSTRACT:
A bow contact has a gradually curved bow portion coupled by a reverse curved transition portion to a substantially linear attaching portion, and in free unstressed condition the latter portion defines an acute angle with a line drawn between the opposed remote ends of the contact, whereby when the contact is deformed to position the attaching portion in flat abutting engagement with a support surface creating a pre-stressed moment in the transition portion a region of zero moment is established in the attaching portion, which remains at zero moment and in flat abutting engagement with the support surface over a wide range of deformations of the bow portion. The bow contacts may be incorporated in an electrical connector arrangement to provide connections between respective conductors of a multiple conductor electrical cable and corresponding connector pins of a male electrical connector, for example, using a printed circuit board interface, and may similarly be incorporated in an output connector for a printed circuit board.
