ABSTRACT:
A watertight lamp socket for lamp belt mainly including a seat having an internally threaded upper portion and a downward opened lower recess portion, a conductor extending across the lower recess portion of the seat, and a bottom cover screwed to a bottom of the lower recess portion to clamp the conductor between the seat and the bottom cover. A sealing member is put around a joint of the lamp socket and a lamp screwed into the internally threaded upper portion of the seat, so that a contact surface between the lamp and the sealing member is watertight. Two contact holes are provided on a top of the lower recess portion of the seat for two screws to downward extend therethrough and pierce into the conductor, so that current is supplied from the conductor via the screws to two conducting spring plates connected to the screws and to the lamp. The contact holes have downward flanges tightly pressing against the conductor to prevent any rainwater or moisture from permeating into the contact holes via the flanges to wet the screws and the conducting spring plates.
