Abstract

Improved safety device for connection and disconnection of electric meters and auxiliary devices, connected through measuring transformers and in their verification without cutting off the power supply, essentially characterized by the fact of consisting of a plurality of juxtaposed and joined insulating molded tablets laterally, that in two laterally opposite portions they lodge terminals for the connection of as many terminals of conductors corresponding to different circuits and that are retained with the help of screws incorporated in the terminals which comprise a transverse hole for the plug of pegs belonging to cables for connecting test devices, to whose terminals are connected, on one side thereof, two fixed contacts, and on the opposite side of one of them another fixed contact adjacent to another fixed contact counterpart associated with a short circuit board and subject to the tablet, finding the two pairs of contacts housed in an intermediate open area of the tablet where the cam consists of a disk with two diametrically opposed recesses, all the cams corresponding to the various pads being joined to a common axis being attached to a control arranged on one side of the block and each tablet comprising two pins external to the cam and diametrically aligned with it and to which are joined pairs of mobile bridge contacts combined with the fixed, against which spikes act the two smooth portions of the cam so that the contacts mobiles are separated from the fixed ones against which the first ones are applied when the pegs fit in the recesses of the cam to close the corresponding circuit, whose pegs are requested against the cam by respective springs housed in cavities of the wafer.
