Abstract: An electrical connection tower as a push-in part with a plurality of receptacle outlet inserts for system voltage connections and for information connections, an annular surround which is recessed in a table top engaging with guides in rails of the connection tower and a cover arranged on the top of the connection tower closing off the top side of the annular surround. The technical problem is that of providing a connection tower with a flush termination of the equipment plate in the unused state and ease of handling. The cover can be swung up counter to a prestressing force about a hinge pin aligned parallel to the plane of an insert plate of a receptacle outlet insert on the insertion side of the insert plates.
Abstract: An adapter box having a base structure that has an annular sealing ridge on the cover side and with a cover that has a sealing effect with an annular sealing strip in conjunction with the sealing ridge. The technical problem is complete sealing of the adapter box in the area of the cover and of a connector so that jet-proofing is attained. The sealing strip (54) has a trough-shaped section (35) overlapping the sealing ridge (7), and the sealing ridge (7) has two tongues (32) separated by a gap (33). Each window (11) formed as a cutout in a wall (3) has a contour consisting of straight sections (12) and centric arc sections (13) with the same radius, which together form in each case a one nth partial arc, with n=3, 4 . . . , of the full arc. The collar (18) of the sealing flange has an external contour identical with the contour of the window (11).
