Connection housing for aligned bus bars
First Claim
1. In a connecting means, for the electrical coupling of ends of first bus bars of rectangular section, placed parallel at the interior of a protection sheath, to other similar bus bar ends placed opposite to said first bus bars, said means comprising conductive clips which are each applied resiliently on the ends of two bars situated in a same plane, and housings in insulating members disposed between the bus bar ends and parallel to the bars serving for the support and insulation of the said clips, the improvement that, with each pair of ends of coplanar bars there is associated at least one clip constituted by two rigid contact bridges perpendicular to said plane, the extremities of which bridges, placed opposite to each other and carrying contact buttons, are submitted locally to the action of a resilient element which urges them together, respective arms of said contact bridges being disposed at each side of a rotary locking element which has cam surfaces cooperating when in a predetermined position with said arms to separate them, said rotary locking element being pivoted in two bearings on insulating elements at each side of a housing for said clips.

Abstract
A connection means serves for the electrical coupling of ends of bus bars situated in protection sheaths, and has clips under the action of resilient members and associated with each phase to be connected, the clips being actuated by as many locking means as there are phases to be coupled. The heads of the locking means have a shape and arrangement such that the mechanical association of the upstream and downstream sheath ends can only be effected in the open state of the clips, while the positive closing of the device can only be effected in the inverse state.
