Flush-mounted cabinet - _ [- ■ -''- . "■ '... ν.

UP distributors are known which are made from sheet steel and are subsequently given an insulating material lining. Such an insulating lining., Has been proposed.,. by applying (pouring, painting or spraying) an isolating agent or by drawing in a ;; Foil -in suction; -or -: .- Printing process. The known methods are / therefore complex / and costly. Still they are. Fastening means for ■; _ rates interfering with metal, especially; made of insulating material ".

The innovation has set itself the task of the aforementioned disadvantages through a flush-mounted cabinet, which consists of a wall box, Blind frame and SKir consists in eliminating that too connecting parts of the cabinet made of plastic-coated sheet steel, e.g. the front and side parts of Wall box or frame or the bars for fasteners of the wall box are preferably connected to one another by high-frequency welding so that after welding the plastic coating is retained.

According to the innovation, a particular advantage of the cabinet is that the sheet metal parts to be connected have elevations (warts or the like.) preferably opposite to the punching burr, which are created by the embossing of the projection during the welding process and which at least are so high that when fully welded the plastic layer no penetration of the machining burr of the

The size of the area of the elevations is so large that the maximum tearing force of the weld / -by- the adhesion. is given by the plastic layer on the sheet metal and not by the welding point itself. \ v ^{:; ':} -' ^y '' - * ^-: - ■ ;. - ^" '" ■
