Abstract

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.

Claim 4
Dependent Claim 56 words
The bulb socket mounting structure according to claim 2, wherein the locking piece includes a hook extending from the end of the locking piece furthest from the mounting section and extending toward the lamp panel to engage with the engaging section, the hook having an inclined surface relative to a bottom surface of the engaging section.
Claim 5
Dependent Claim 55 words
The bulb socket mounting structure according to claim 1, wherein the locking piece includes a base portion extending radially out from an outer cylindrical surface of the mounting section and a bending portion connected to a radial outward end of the base section and extending tangential to the outer cylindrical surface of the mounting section.
Claim 6
Dependent Claim 52 words
The bulb socket mounting structure according to claim 4, wherein the locking piece further includes a hook extending toward the lamp panel from an unconnected end of the bending portion, the hook engaging with the engaging section, the hook having an inclined surface relative to a bottom surface of the engaging section.
Claim 7
Dependent Claim 38 words
The bulb socket mounting structure according to claim 5, wherein the hook further includes a steep surface, wherein the steep surface has a greater incline than the inclined surface relative to the bottom surface of the engaging section.
Claim 8
Dependent Claim 217 words
A bulb socket mounting structure, comprising: a lamp panel having a mounting hole; a bulb socket having a mounting section where a lamp is mounted, the mounting section inserting into the mounting hole, the bulb socket moving between a socket inserting position and a socket locking position, said socket inserting position being an initial inserted position of the mounting section in the mounting hole, said socket locking position being a position where the bulb socket is fixedly mounted to the lamp panel and inhibited from being removed from the lamp panel; locking means for locking the bulb socket to the lamp panel; and engaging means for engaging with said locking means, wherein one of the mounting section of the bulb socket and the lamp panel includes the locking means, another of the mounting section of the bulb socket and the lamp panel includes the engaging means, the locking means bending to permit the bulb socket to rotate from the socket inserting position to the socket locking position, the locking means engaging with the engaging means to stop the bulb socket when the bulb socket reaches the socket locking position; and a relief groove provided near an inlet of the engaging means so the locking means is prevented from being bent until immediately before engaging the engaging means.
