Abstract

A contact sub-assembly is provided for an electrical connector. The contact sub-assembly includes a printed circuit and an array of mating contacts. Each mating contact includes a terminating end portion and a mating interface. The contact sub-assembly also includes an array of circuit contacts that is discrete from the array of mating contacts. Each circuit contact is engaged with and electrically connected to the printed circuit. Each circuit contact is separably engaged with and electrically connected to the terminating end portion of a corresponding one of the mating contacts such that the array of circuit contacts electrically connects the array of mating contacts to the printed circuit.
