Patent ID: 7367810

Claim:
A strain gauge interfacing cable connector which selectively connects terminals or connecting pins of a measurement equipment with terminals or connecting pins of a strain gauge sensor, said measurement equipment being compatible with four types of interfacing wiring, 120Ω quarter bridge wiring, 350Ω quarter bridge wiring, half bridge wiring, and full bridge wiring, said strain gauge interfacing cable connector comprising: a DIP switch having 4-pole switching mode, a cable containing seven electric wires, all one ends of which are connected with terminals or connecting pins of the measurement equipment via a commercial connector, four other ends of which are connected with equipment-side four switching poles or terminals of the DIP switch respectively, and three other ends of which are connected with three terminals or connecting pins of the strain gauge sensor respectively; an electric wire contained in said cable, one end of which is commonly connected with second, third and fourth sensor-side switching poles or terminals of the DIP switch in a way of parallel connection, and the other end of which is connected with a terminal or pin of the strain gauge sensor; a jump wire contained in said cable, one end of which is connected with equipment-side fourth terminal or pole of the DIP switch and the other end of which is connected with sensor-side first terminal or pole of the DIP switch, whereby the DIP switch can be manipulated to select one of the four types of interfacing wiring; and a shield wire contained in said cable, one end of which is connected with a shield terminal or pin of the measurement equipment, and the other end of which is connected with a shield terminal or pin of the strain gauge sensor.
