Schweitzer, Jr, E O

An automatic clamping mechanism is described for mounting a circuit condition monitoring device to an electrical cable, comprising: a housing for the monitoring device; a pair of clamp members projecting in generally parallel-spaced relationship from spaced locations on the housing; at least a portion of the projecting end of each of the clamp members being pivotal toward the other of the clamp members, so that each of the members encircle at least a portion of the cable when the cable is positioned between the inwardly pivoted members; biasing means associated with each of the clamp members for biasing and projecting portions toward each other; and trigger means including an elongated laterally deformable trigger member extending between the projecting portions for maintaining a spacing between the projecting portions greater than the diameter of the conductor. The trigger member is longitudinally non-compressible in the absence of a lateral deformation to prevent the projecting portions from pivoting toward each other, but longitudinally compressible upon lateral deformation resulting from lateral engagement with the conductor to allow the clamp members to encircle the conductor.
