1. An electrical connector, comprising:a housing; and
a plurality of terminals supported by the housing, at least two of said plurality of terminals comprise:
an electrically conductive base;
a contact beam that extends from said base and is monolithic with said base, said contact beam including a contact portion; and
a mounting portion that extends from said base and is monolithic with said base for mounting said terminal to a substrate, wherein at least a portion of the mounting portion extends from the housing to form an interface to the substrate;
said plurality of terminals are arranged cylindrically around an insertion axis to form a receptacle for receiving a plug therein, wherein:
contact portions of said at least two terminals face said insertion axis and any two of said at least two terminals lie on a chord across said receptacle; and
the chord intersects the electrical connector only at the two terminals.
