ABSTRACT:
A lamp base structure of a series of Christmas lamps, wherein a through hole and an engaging hole are installed on the central portion and the near rim portion of the groove seat, respectively, while a central conducting piece and an outer conducting piece are installed in the through hole and the engaging hole. An engaging groove is formed on the inner peripheral wall of the lamp base corresponding to said engaging hole. A bent portion is formed between the upper end penetrating portion and the lower end portion of the outer conducting piece, and the penetrating portion is shifted toward the center of the lamp base groove. An engaging block is engaged in the gap of the engaging hole above the bent portion of the outer conducting piece, wherein the width of said groove engaging hole corresponds to the length of the bent portion between the lower end portion and the upper end penetrating portion of the outer conducting piece. A protrusion is located on the upper end penetrating portion of the outer conducting piece. A gap is located between the protrusion and the lower end portion. An engaging block fits snugly in the gap and has a length greater than 1 mm. Thus the present invention will attain a preferred water-proof effect.
