Guide rail for lateral guiding and holding, steekable

The invention relates to a guide rail to the side Guiding and holding of pluggable flat modules, which are arranged parallel to one another with a high packing density. and printed circuit boards grouped together in wiring fields sufficient heat dissipation by means of ventilation and / ' or convection guaranteed

The individual circuit parts are used in larger electronic systems summarized in pluggable flat modules and electrically connected to one another. The printed circuit boards are
