CLAMP INCLUDING FIXED AND MOVABLE JAWS FOR MEASURING A GROUND LOOP CURRENT

摘要

A clamp for measuring a ground loop current includes a first jaw secured to a fixed support and a second jaw pivotally mounted on the fixed support, and pivotable between a position closing the clamp and an open position, and an elastic element for returning the movable jaw to the closed position. The clamp includes a device scaling down the force required for opening the clamp, by application of the force to a trigger. The device is mounted between the elastic return element and the trigger, upon opening the clamp.

1. A clamp for measuring a ground loop current, the clamp comprising:
a support; a first jaw secured to the support; a second jaw pivotaly mounted on the support, and movable between a closed position of the clamp in which an end of the second jaw is urged into contact with an end of the first jaw, and an open position of the clamp; an elastic element urging the second jaw toward the closed position; a lever, including first and second arms, that pivot around an axis on the support, wherein the second jaw is located on the first arm and the second arm forms a trigger for pivoting of the lever between the closed and open positions of the clamp; and a device for scaling-down force required for opening the clamp and applied to the trigger, relative to force required for maintaining the second jaw in the open position, wherein the device is mounted between the elastic element and the trigger.
