Title: Frame for the mounting of interchangeable electrical units

Abstract: A novel article of manufacture for mounting interchangeable electrical units having oppositely directed projections is disclosed. The article consisting of a one-piece mounting frame formed of insulating synthetic plastic material has a row of openings extending between front and rear surfaces into each of which a unit may be inserted until arrested by an abutment provided in each opening. A frame stiffening member having recesses to receive first projections of the units while the units are being inserted into each opening extends along one side of the row of openings and faces another stiffening member located on the other side of the row and having elastic tongues which are yieldable from a first to a second position by the second projections of the units during insertion. Upon insertion, the tongues reassume their first positions, thereby retaining the units. Passages are provided in the frame for insertion of a tool to deflect the corresponding tongues and demount the units.
