Installation distributor housing for in-built electrical appts. - provides alternating, rotationally symmetrical projections and recesses for coupling identically profiled intermediate pieces between base plate and cover

摘要

An installation distributor for use with electrical equipment has two identical head units (1) that fit onto an intermediate module (2). The units are box-shaped. The head units have projections (5) and recesses (6) that engage mating surfaces on the intermediate module (5). The surfaces of both the head units and the intermediate modules are symmetrical. Edges of the units are grooved to locate together and are held in a latched position. ADVANTAGE - Simple construction allowing parts to latch together force fittingly in number required without additional coupling pieces.
