US Patent 7184273 Electronic device with protective housing having enhanced rigidity

An electronic device includes a printed circuit board, a housing in which the printed circuit board is accommodated, a cover covering an end opening of the housing, and a connector disposed on the printed circuit board which has an end exposed through an aperture of the cover outside the housing. The housing has an improved structure characterized by at least one protrusion formed on an inner face of a top wall of the housing, a bend in the top wall of the housing, and a table protruding outwardly from one wall of the housing on which a nameplate is attached. When the connector is rotated around a portion of the inner circumference of the cover defining the aperture, the at least one protrusion or the bend stops the rotation of the connector. The improved housing structure ensures a high rigidity of the housing and easy assembly of the electronic device.
