Abstract
Abstract A expandable housing for an electronic device allows additional modules to be received in a simple manner so as to build on a base module and which is suitable for use in a vehicle. The housing comprises a frame, in which provisions are made for receiving a printed circuit board, a base assigned to the frame and a cover, which base and cover are identically constructed, as well as a hood which is fastenable at the frame and serves to hold cables. The frame, cover and base are connected with one another by means of groove-and-tongue connections and are held together, in addition, by through-screws.
