Abstract

An improved structure for a decorative lamp, in which an end opening of a cylinder part under the socket for inserting power wires is provided with two sets of positioning slots having different depth; each of the positioning slots is furnished with a guide slot between the inside and the opening thereof; the diameter of the guide slot is slightly less than that of the positioning slot; the set of deep positioning slots is used for laying and fastening two power wires respectively; a fixing cap to be assembled with cylinder part of the socket is furnished with two semi-circular posts in the central part thereof; the outer part of the fixing cap is provided with a round flange; at least two positioning studs are furnished between the bottom part of the semi-circular posts and the round flange; the positioning studs are to be mated with the shallow positioning slots on the end opening of the cylinder part of the socket. The round flange of the fixing cap is provided with at least two pairs of high flange studs opposite to the end opening of the deep positioning slots on the socket respectively; between two high flange studs, there is a round slot. The power wires pulled out of the socket are to be laid through the round slots between the high flange studs so as to be fastened in place respectively.
