A housing for electrical components is formed by a series of extruded panels connected edge to edge. The first edge includes a slot defined by an inner wall and an outer wall and the second edge includes a blade inserted into the slot, the blade and the flexible wall including co-operating shoulders. The blade and slot are at an angle to the outer surface where a rib engages into an outer recess to seal the outer surface at the joint. A bridging member spans the joint to prevent spreading, while locking the flexible wall and carrying internal components. The housing can form a post or a receptacle on top of the post. The bridging members connect to end plates by screws extending though the plates so as to form an internal structure for the housing. Some of the connected panels can include cooling fins forming a cooling duct. |
