I claim: 1. An electronic device, comprising: a front wall; a built-in housing part comprising a cover, a base, side walls, and a rear wall; a printed circuit board arranged transversely in relation to said rear wall and connected to at least two housing element of the built-in housing part, said b
I claim: 1. An electronic device, comprising: a front wall; a built-in housing part comprising a cover, a base, side walls, and a rear wall; a printed circuit board arranged transversely in relation to said rear wall and connected to at least two housing element of the built-in housing part, said board carrying electronic subassemblies and components of a built-in device as well as a plug socket wherein access to contacts of said plug socket is facilitated through an opening in said rear wall, said board further comprising at least one through-hole for fastening, in combination with an appropriate size screw, said board in said housing, said at least one through-hole having a larger diameter than a shank diameter of said screw, said larger diameter being a product of a sum of production tolerances of at least said board and housing; guiding surfaces formed on said plug socket, said guiding surfaces being substantially parallel to said rear wall; wherein said housing is comprised of a steel sheet joined together so as to form a cover component and a base component, said cover component preferably being formed by a cut-to-size blank comprising a cover plate, said side walls and said rear wall and in that at least one guide strip is formed directly on said rear wall; and a guide strip is formed on a plate which is formed onto the rear wall and serves for connecting said rear wall to said side wall. 2. The device according to claim 1, wherein said plug socket is aligned substantially parallel to said printed circuit board. 3. The device according to claim 1, wherein said guiding surfaces are formed on said plug socket at substantially right angles to the direction of said plug-in contacts. 4. The device according to claim 1, wherein said guide is formed by cooperation of said rear wall and guide strips attached to a built-in housing part. 5. The device according to claim 1, wherein said guide strips are formed on opposite sides of said opening and at right angles to a fastening plane of said printed circuit board. 6. The device according to claim 1, wherein a guiding surface assigned to said rear wall is formed on the plug socket. 7. The device according to claim 1, wherein said guide strips are formed by opposing tongues protruding into said opening, alternately provided essentially planar to the rear wall and parallel to the rear wall, and in that guide rails corresponding to a distance between said tongues, provided transversely to the guiding direction, are formed on said plug socket. 8. An electronic device comprising: a front wall, a built-in housing part comprising a cover, a base, side walls and a rear wall a printed circuit board, arranged transversely in relation to said rear wall connected to at least two housing elements of said built-in housing part and carrying electronic subassemblies and components of said built-in device and a plug socket, access to contacts of said plug socket aligned parallel to said printed circuit board and available through an opening provided in the rear wall of said built-in housing part, guiding surfaces formed on said plug socket at right angles to a direction of said contacts, wherein said guiding surfaces are associated, within the built-in housing part, with a guide parallel to said rear wall, without any play, and in that holding-down means, allowing relative movements between said printed circuit board and said side walls, are provided for fastening of said printed circuit board on a support formed by lugs provided on said side walls of said built-in housing part; wherein said housing is comprised of a steel sheet joined together so as to form a cover component and a base component, said cover component preferably being formed by a cut-to-size blank comprising a cover plate, said side walls and said rear wall and in that at least one guide strip is formed directly on said rear wall; and a guide strip is formed on a plate which is formed onto the rear wall and serves for connecting said rear wall to said side wall.
