ABSTRACT:
A device for terminating a coaxial cable to a printed circuit board with a minimum of impedance mismatch is disclosed. The terminator includes a conductive body having a plurality of legs which are designed to pass through holes in the printed circuit board to mechanically attach a coxial cable to the board and electrically terminate the shield of the coaxial cable to an appropriate circuit on the board. The coaxial cable is mechanically connected to the conductive body by a heat shrinkable sleeve, the shielding of the cable being first exposed so that it can make an electrical connection with the conductive body. The center conductor of the cable is bent at right angles with the axis of the cable such that it too will pass through a hole in the printed circuit board and be electrically connected to an appropriate circuit on the board. This bend is made within the confines of a pair of tabs formed on the conductive body which hold the dielectric surrounding the center conductor and in effect form a continuation of the shield so that the impedance of the termination is kept relatively constant.
