Securing mechanism used in miniature Christmas light bulb sockets

摘要

A securing mechanism used in Christmas light bulb series mainly comprises a light bulb socket having a pair of longitudinal guide rails formed on two side wall surface thereof and a plurality of transverse ribs disposed between two guide rails. The transverse ribs have a triangular cross section with an inclined top side and a horizontal bottom side. The securing mechanism also includes a U-shaped fastener that has horizontal locking ribs disposed on the inner wall surfaces on two ends thereof. The locking ribs have a cross section with a horizontal top side and an inclined bottom side. The fastener mounts on a support frame and holds on two sides of the socket to secure and locate a socket at arbitrary position along the support frame with a desired inclination angle.
