Busbar Adapter

A busbar adapter (100) comprising:

• a lower-deck element (200, 200′) with a lower side having at least one fastening element (220) for fastening the busbar adapter (100) to one or more busbars, and
• an upper-deck element (400, 400′, 400″) for fastening electrical appliances, that can be releasably connected to the lower-deck element (200, 200′),
• characterized in that
• one of the upper-deck element (400, 400′, 400″) and the lower-deck element (200, 200′), has an end wall (440, 442) having at least one opening (460, 462) and the other of the upper-deck element (400, 400′, 400″) and the lower-deck element (200, 200′) has an end wall (240, 242) having at least one projection (260, 262),
• the lower-deck element (200, 200′) and the upper-deck element (400, 400′, 400″) arranged such that the upper-deck element (400, 400′, 400″) can be placed onto the lower-deck element (200, 200′) in a motion direction relative to the lower-deck element (200, 200′), so that the upper-deck element (400, 400′, 400″) can be brought into an operating position, this relative motion direction comprising at least one motion component being one of parallel and anti-parallel to a longitudinal axis (A) of the lower-deck element (200, 200′), so that in the operating position of the busbar adapter (100) the at least one projection (260, 262) protrudes at least partly into the at least one opening (460, 462), and
• the busbar adapter (100) further comprising a locking device (300, 300′) with a locking position that prevents the upper-deck element (400, 400′, 400″) from shifting relative to the lower-deck element (200, 200′) in one of a direction parallel and anti-parallel to the longitudinal axis (A) of the lower-deck element (200, 200′).
