Supply voltage contact rail arrangement for assembly group carrier

摘要

The invention concerns a device for providing supply voltage to a mounting rack (10) multipoint connector (20), characterised in that the multipoint connector (20) pins are divided into two groups: one first group connected to a bus system (22) lines (24) and optionally to an element supplying voltage to the system and a second group of pins. Said second group pins project sufficiently from the rear connecting wall (18) to enable the voltage transmission card (28) to be plugged in, which itself is connected to at least a conducting bar (36) guiding the system power supply.
