Earthing conductor element for switchboard terminal blocks and associated terminal block for earthing earth wires

A conductor element for switchboard terminal blocks comprising a conductor body, the conductor element comprising:

• a conductor lamina extending in a longitudinal direction and designed to electrically connect together two wires in the longitudinal direction;
• a substantially vertical shaped body extending in the longitudinal direction, connected to the conductor lamina and having a bottom body section, the bottom body section including:
• a bottom free edge extending in the longitudinal direction, the bottom free edge including a first edge section for resting in a vertical direction on a first flange of two folded flanges of a DIN-standard rail;
• a first end proximal to said first edge section and including a bottom edge having a first tooth for engaging with the first flange of the DIN-standard rail;
• a second end opposite to the first end;
• wherein the bottom free edge has a second edge section proximal to said second end and aligned in the vertical direction with the first edge section, for conductively resting in the vertical direction on a second flange of the two folded flanges of the DIN-standard rail;
• a flat-lamina spring including a head and two flat-pin legs which are separated by an interspace;
• wherein said second end is adapted to engage and retain the flat-lamina spring;
• and
• wherein the respective free ends of the two flat-pin legs are resiliently deformable so as to be arranged, during use, to contact and push on the second folded flange of the DIN-standard rail for engaging therewith, and to allow operation of the flat-lamina spring for disengagement from the rail.
