A terminal assembly is provided for terminating a center conductor of a coaxial cable. The terminal assembly includes a terminal body having a pin at one end and a cavity at the other end for accommodating a center conductor therein. A contact member is supported within the cavity. The contact member includes plural inwardly directed cantilevered beams extending from a contact base for deflectable engagement with the inserted center conductor. The terminal body includes an inwardly directed shoulder for engagement with the beams at a location between the base and the distal ends of the beams. The location defines a deflection fulcrum at a location distal from the base so as to provide increased contact engagement force between the distal ends of the beams and the center conductor.
