Industrial box for electrical elements

摘要

The box has a base (11), cover and walls (12). The walls have overlapping edges and chamfered corner pieces (13) designed to join in a sealed way to the lateral walls (12). The lateral edges (12b) of the lateral walls, formed from a single piece of folded material, are chamfered with respect to the plane of the walls. The angle pieces (13) are over-moulded on the chamfered edges. Theses edges (12b, 12c) have holes in them through which the over-moulded material passes and fixes the external and internal parts together, thus enabling the angle pieces to resist any effort to extract them towards the exterior (C1).
