Abstract: A heat transferring device comprises two massive thermally conductive bodies arranged vertically on top of one another and spaced apart by a variable distance. One or more spreading elements are positioned between the thermally conductive bodies and respectively comprise two horizontally movable wedges with wedge tips pointing in opposite directions and a spring pressing apart the wedges. The thermally conductive bodies have corresponding sliding surfaces extending parallel to the wedge surfaces. Motion of the wedges in the horizontal direction is converted into vertical motion of the thermally conductive bodies to thereby automatically adapt the height of the entire device to a respective installation situation.

Abstract: A housing for electrical devices is composed of four sheet metal parts, namely a base part, two side parts and a lid. The base part is bent in a U-shape and has a rectangular bottom plate with two opposing connecting edges. Each of the side parts has a lower connecting edge and can be placed laterally against the base part. The lid has a connecting edge and an opposing edge that is folded over. Connecting links and mounting tabs offset inwardly in a Z-shape are arranged on the connecting edges. The mounting tabs engage partially in cutouts of the connecting links, thus forming a hinge-like positive connection of two adjacent housing parts.
