Abstract: The invention relates to a terminal adaptor for a busbar system for the electrically conductive connection of connecting lines to the busbars, in which in each case one contact piece per busbar is held aligned with the busbars in a plastic adaptor part which can be placed on the busbars, in which each contact piece can be electrically conductively connected by means of a U-shaped bracket to the associated busbar, the bracket gripping behind the busbar with terminal ends which are integrally formed on the free ends of its side limbs and a terminal screw which can move in a threaded hole of the web of the bracket clamping the busbar to the contact piece, and in which the contact pieces are provided outside the clamping region of the bracket with threaded holes and/or holes for connection of the connecting lines by means of connecting screws. As a result of the special arrangement of the contact pieces and of the brackets, as well as of the terminal contacts for the connecting lines, a terminal adaptor is produced which requires a minimum amount of space in the longitudinal direction of the busbars, even in the case of a three-conductor busbar system.
