LAMP SOCKET AND LUMINAIRE

PROBLEM TO BE SOLVED: To provide a lamp socket capable of preventing breakage of a contact part. SOLUTION: A socket body 9 is rotatable with respect to a support body 10 between an open position allowing insertion of lamp pins 4 and a close position allowing contact parts of a conductive plate to contact and be electrically connected to the lamp pins 4. Lock projecting parts 49 elastically locking the lamp pins 4 to normal connection positions are projected on the inside surfaces sandwiching the lamp pins 4 in a guide slit 35 of the support body 10. When the socket body 9 is intended to be rotated from the open position to the close position when the lamp pins 4 are located on the side close to an operation window 34 relative to the lock projection parts 49 of the support body 10, the socket body 9 abuts on the lamp pins 4 before the contact parts of the conductive plate abuts on the lamp pins 4, and the rotation of the socket body 9 in the direction toward the close position is blocked. Accordingly, the contact parts of the conductive plate are prevented from being broken by being excessively deformed. COPYRIGHT: (C)2009,JPO&INPIT
