Electronic panel

Claim 1

An electronics panel comprising: a unitary extrusion of substantially constant cross section adapted to be horizontally mounted to a supporting vertical structure, said extrusion including a back plate having a front surface and a back surface adapted to be mounted flush to the supporting structure, a top plate projecting forwardly from the front surface of the back plate at a position spaced downwardly from the top edge of the back plate, a front plate parallel to the back plate and projecting downwardly from the forward edge of the top plate with the lower edge of the front plate spaced upwardly from the lower end of the back plate and being structurally unconnected to the back plate to produce a space between them, said extrusion further having a clip near the juncture of the front surface of the back plate and the bottom surface of the top plate and a snap near the lower edge of the back plate; and a circuit board having parallel edges, one edge inserted in the clip and the other engaged by the snap to secure the circuit board to the extrusion, said circuit board including a row of connector elements near the edge of the board engaged by the snap so that the connector elements are exposed below the lower edge of the front plate and allow for passage of air upwardly between the front and back plates of the extrusion to cool the circuit board.
