Fastening device for fastening an electronic component

A rack for storing electronic components, comprising:

• at least two spaced-apart, vertically extending sheet-metal angled rails having a row of holes, the mutually facing first legs of which delimit an opening and to which at least one electronic component is fastened;
• wherein the electronic component has a width substantially corresponding to the opening and at least two fastening tabs which project outwards at a front side at their edges are arranged adjacent to the first legs, and have holes aligned with holes of the row of holes;
• and
• wherein a fastening device is fastened to the first legs, the fastening device including a plate configured to be placed on a side wall of the component, the plate having a fastening section bent along a bending line, the fastening section having at least one first fastening bolt that extends away from the plate and penetrates the hole of the fastening tab;
• wherein the component is supported in a positive-locking manner against gravity on the fastening devices;
• and
• wherein the plate has a positive-locking element which acts in a direction of the bending line and can be brought into positive-locking engagement with the component in order to support the component against gravity.
