Tip for weapons used in fencing - has button with dead travel before registering electrically by stem contacting bottom terminal

摘要

The end of the fencing weapon (1) is hollow and has an insulating plug (3) in the bottom, with a terminal (4) electrically connected to the scoreboard. The tip is inside an insulating sleeve (9), sliding in the bore and another terminal (8), having a long stem, is retained by the sleeve. A ferrule (10) around the stem holds a washer (15) against a ring (16) fixed to the bore wall. Springs (12, 14) retain washer and ferrule. On contacting an opponent, the first part of the tip's travel retains the washer against the ring and is not electrically registered. Electrical registering only occurs when the stem (8) contacts the bottom terminal (4).
