<P>PROBLEM TO BE SOLVED: To allow opening/closing of a current clamp by an operation or drive at a place separated from the current clamp in a current measurement probe. <P>SOLUTION: A current measurement probe 10 includes a current clamp 12, a connection tube section 14 and a measuring device 16. The connection tube section 14 is configured in double structure of a fixed tube 54 including a signal line 52 and an operation tube 56 movable in an axial direction at the outside of the fixed tube 54. The current clamp 12 is constituted of a fixed side clamp 22 and a movable side clamp 24, which are connected by a rotational axis 26 of the fixed side clamp 22 and a rotational hole 27 of the movable side clamp 24 as rotation parts. On the movable side clamp 24, an opening/closing force point section 28 is arranged at a position separated from the rotation part by a predetermined rotation radius, so as to be pushed or returned by a slider 40 prepared at a tip of the operation tube 56. The current clamp 12 is thereby opened and closed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
