Abstract: An electrical connector assembly 10 includes a receptacle member 12 and a pin header 60. The receptacle member 12 has housing means 14 including an inner body portion 22 and two opposed outer side walls 24, which together define elongate cavities 36 between inner body section 22 and respective outer side walls 24; and a plurality of first contact terminal members 40 disposed in inner body portion 22 and a plurality of second contact terminal members 46 disposed in the elngate cavities 36.

Abstract: A high speed, high density, controlled impedance connector for use between printed circuit boards is disclosed. The connector provides for both power and signal transmission. Closely spaced signal terminals are surrounded by dielectric sleeves positioned in an array, and the plural dielectric sleeves are in turn surrounded by an outer unitary cast conductive housing. The essentially coaxial configuration of the contacts permits minimal variations in the impedance along the length of the signal paths in the connector. The connector is fabricated by first positioning the dielectric sleeves in spaced relationship on prescribed centerlines and subsequently casting or molding the conductive outer housing around the sleeve array.

Abstract: An adaptor to couple a connector to a conductor of a flat, high performance, electrical cable is disclosed. The adaptor includes two mating halves through which the conductors pass. The adaptor is formed with an internal recess and further includes a ferrule therein to allow an electrical ground connection to an EMI shield of the cable. The adaptor is also formed with external threads whereby a threaded nut may be employed to maintain the adaptor halves operatively couples. The connector can then be attached to components of an electrical system without significant radiation occurring at the interconnection.
