The lid part is formed to extend over the box part front side and parts of its upper side, leaving a gap between the lid part and the box part rear wall (30), which has several through apertures (31, 32) for cables and on it are firmly located contacts which at a distance from the upper edge has counterpoised pins (43) extending into the box part. The box part (20) rear wall (30) near to its upper edge also has a backwardly extending flange (33). The box part on its under side has fixtures (40, 41) for an externally installable branch outlet. The box part on its inside, preferably near to the rear wall upper edge, has stirrups (45, 48) for union or tension straps. Distance ribs (48) are formed on the inside of the box part rear wall, at least near to its upper edge. |
