A surge protection element (50) for a conventional cable connector (10) includes a printed circuit board (50) preferably shaped as two concentric rings (58,54) connected by two spokes (56,57). The outer ring (54) is electrically connected to the grounded portion of the cable connector body. A printed circuit trace (62) on one of the spokes is separated from a printed circuit trace (66) on the inner ring (58) by a spark gap. If a high voltage surge is carried by the coaxial cable transmission line, a spark is formed in the gap. As a consequence, the high voltage surge is transferred to the surge protection element (50) which in turn conducts the electricity to the grounded body of the connector (10). |
