ABSTRACT:
A bulb socket mounting structure inhibits a bulb socket mounted on a panel from being turned to prevent the bulb socket from unintentionally coming off the panel. The bulb socket mounting structure includes a bulb socket with a fixing flange and a locking piece extending from the fixing flange. The locking piece includes a bending portion extended tangentially off an outer cylindrical surface of the fixing flange with a hook at the end of the bending portion away from the fixing flange. The panel forms an engaging recess at a predetermined position to fixedly engage the hook of the locking piece. A relief groove has an inclined guide surface at the end abutting the engaging recess. When the bulb socket is inserted into a mounting hole formed in the panel, the hook engages the relief guide. From this position, the bulb socket rotates toward a socket locking position. The hook of the locking piece moves along the relief groove without bending the locking piece. Immediately before being engaged with the engaging recess, the hook slides up the inclined guide surface while bending the locking piece. Finally the bending locking piece is restored when the bulb socket enters the socket locking position where the hook engages the engaging recess.
