Abstract: A collective connection device for wire conductors of electrical power distribution systems accommodates a compact arrangement of a multiple number of smaller and larger terminal blocks on a busbar. The busbar of the device is divided into two primary decks respectively located at the first and second ends of the busbar and upper and lower centrally located decks which form an electrical bridge between the primary end decks.

Abstract: This invention proceeds from the type of stackable connectors for printed circuit boards, and it addresses the problem of being able to fasten such terminals in pricise and stable position to a printed circuit board, so that the solder connections of the terminals can be soldered to the conductive tracks with no problems. It is suggested to provide such connectors with a narrow-base catch peg that is located next to the solder connection of the terminal in the direction of stacking, with the width dimension measured across the solder connection and the narrow-base catch peg being equal to or smaller than the grid spacing of the conductive tracks of the printed circuit board.
