Abstract: A housing for electrical and electronic components includes several flat-shaped wall panels held together by specially shaped corner joints. The corner joints are formed from simply assembled, economically manufactured sections designed for different sized housing, and provide a simple, secure and tight connection of the housing wall panels which cannot be seen form the housing exterior. The corner joints comprise two interlocking extruded sections, one of which can simply be fixed to an adjoining wall panel as a connecting section and the other is a cover section which can quickly and securely be fixed to the connecting section. The cover section has a rounded corner which blends smoothly into the wall panels. The fixing of the inner connecting section is achieved in an sturdy manner by screws and the external cover section fits conveniently and easily onto the connecting section. This housing, besides being a simple and sturdy construction, offers the advantage of flap packing for despatch.
