Support frame for electrical modules or sub-assemblies - is earthed by means of metal blocks which have slotted recess in one side face

摘要

The support frame or carrier comprises side plates (10), ending on the rearward side in a free vertical end-edge, and transverse carriers which have an end flange on the rearward side. The module carrier is earthed by means of metal blocks (30) which have a slotted recess (38) provided in one sideface. The width of the recess (38) is matched to the max. thickness of the a side-plates (10) and the max. thickness of the end-flange (21) of the transverse carrier (20) so that it can be selectively fixed on the end-edge (11) of the side-plate (10) or on the end-flange (21) of the carrier (20). ADVANTAGE - Simplified earthing system.
