Claim:
An electronic device comprising: a housing comprising a window defined thereon; a circuit board received in the housing; an infrared receiving device received in the housing and electrically connected with the circuit board; and a protection cover engaged in the window of the housing to cover the infrared receiving device, the protection cover comprising a blocking plate, a side wall extending outwardly from the blocking plate, and two clasping ears respectively located at two opposite sides of the side wall, the blocking plate being attached to the housing, the two clasping ears of the protection cover being clasped onto the housing; wherein the side wall defines a through hole in the centre thereof, and portions of the side wall between the clasping ears and the blocking plate are removed to communicate with the through hole, for encouraging elasticity in the side wall to avoid a fracture of the side wall by deformation during assembly when the protection cover engages in the window.
