Right angle coaxial jack connector

A right angle coaxial jack connector for intermating ground and signal paths of a coaxial plug connector to a printed circuit board including a metallic shell having a plurality of metallic grounding pins protruding from the shell bottom surface adapted to fit within holes of printed circuit board to electrically ground said shell to the ground circuit of said board and to mechanically hold said jack to said board through being soldered thereto, said shell further including a central bore leading to a rear face, an insulating sleeve fitted in said bore including a sleeve bore coaxially positioning a connector signal contact within said shell, a keyway in the said rear face of said shell adapted to receive the insulating sleeve carrying the said signal contact inserted along the shell bore axis into position within said shell, the said signal contact having a forward end adapted to mate with a coaxial plug connector and a rear end at right angles to the axis of the said shell bore adapted to extend into a printed circuit board to be connected to a signal trace thereof, the said rear end of said signal contact extending between the said ground pins, an insulating disc surrounding the rear end of said signal contact to hold said contact coaxially positioned within said shell, a metallic cap fitted into the rear face of said shell to close off the said keyway and seal the said shell in conjunction with the said insulating sleeve and disc against entry of contamination within the said shell and reduce radiation emitted from the said plug connector or transmitted from the exterior of said shell to provide improved RF characteristics.
