Abstract: A female electrical connector formed of sheet metal to receive a cylindrical male pin. The connector is configured as hyperboloid of revolution with the generatrices comprising a plurality of flat and straight beam members disposed between a pair of cylindrical ferrules. The beam members bear against the inserted pin along a contact length so the bearing therebetween is a surface of each beam member partially wrapping around the pin to effect electrical continuity therebetween.The beam members are automatically formed when the ferrules are rolled into cylinders without any part of the tooling touching the beams.

Abstract: An electrical connector contacts assembly having a solid elongated pin member and a hollow socket member each having like cross-sections for closely removably inserting the pin through the socket. The socket body is twisted into a helical configuration while the pin is straight-sided. The assembly of the members reconfigures the more resiliant socket into the configuration of the pin setting up torsional stresses that create a uniformly distributed torsional force load between the pin and socket for achieving low electrical resistance therebetween.

Abstract: Connector assembly having a housing with multiple terminal receiving channels therein, each channel open at one end and closed at the other end with apertured closing members, conductive wires having access to the terminals through the aperture. The housing, and conductive wires are encapsulated within a dielectric plastic.
