Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
89 words
An electrical probe, comprising: an insulative body having a longitudinal axis; a pair of rotatable tip electrodes extending from said body, said tip electrodes being spaced apart at a pivotal end and being disposed at substantially a right angle to the longitudinal axis of said body; and means for simultaneously rotating said tips, wherein said tips are substantially parallel in the open position of said probe and being rotated toward each other through a substantially ninety-detree arc to provide a gripping function in the closed position of said probe.
Claim 2
Dependent Claim
89 words
An electrical probe, comprising: an insulative body having a longitudinal axis; a pair of rotatable tip electrodes extending from said body, said tip electrodes being spaced apart at a pivotal end and being disposed at substantially a right angle to the longitudinal axis of said body; and means for simultaneously rotating said tips, wherein said tips are substantially parallel in the open position of said probe and being rotated toward each other through a substantially ninety-detree arc to provide a gripping function in the closed position of said probe.
Claim 3
Dependent Claim
20 words
A probe in accordance with claim 1 further comprising a resilient member disposed between said body and said tip electrodes.
Claim 4
Dependent Claim
41 words
A probe in accordance with claim 1 wherein said rotating means comprises cam arms formed in the longitudinal axes of said tip electrodes, and a sliding collar operatively connected to said body and having cam surface for engaging said cam arms.
Claim 5
Dependent Claim
45 words
A probe in accordance with claim 1 wherein said rotating means comprises lever arms formed at an angle with respect to the longitudinal axes of said tip electrodes, and a lever operatively connected to said body and having slots therein for engaging said lever arms.
