Patent ID: 6851830

Claim:
An electric connecting structure for a lamp for assembling a lamp rod and wire connecting boxes; comprising: a plurality of wire connecting boxes; each of the wire connecting box having a plurality of inserting holes annularly arranged around a periphery of the wire connecting box; a plurality of retaining seats; an inner side of each wire connecting box being installed with a respective retaining seat; a connecting hole being formed axially in the retaining seat; each of the retaining seats being locked to one inserting hole of each wire connecting box through a positioning stud; a receptacle at rear sides of retaining seats; a conductive seat being installed in the receptacle; each of two sides of the receptacle having a through hole; a positioning screw passing through each of the through hole so as to lock the receptacle into the positioning holes of the retaining seats; a plurality of braking pieces; each braking piece being mounted to a respective retaining seat; a plurality of connectors; a rear end of each connector being locked to a lamp rod; each connector having a braking inclined surface at a rear side thereof; a channel being formed at a middle section of the braking inclined surface; a front end of the channel having a stop wall; each of the two sides of the channel being formed with at least one via hole; and the front end thereof having a stop edge; wherein each connector is embedded into a connecting hole of the retaining seat; and the braking pieces are buckled to a bottom of the braking inclined surface so that the connector is positioned firmly; the positioning studs and positioning screws are protruded from the wall of the connecting holes based on positions of the wire connecting boxes; the stop wall of the channel of the connector is at a position with respect to the positioning studs on the wall of the connecting holes of the retaining seats; in assembly, the stop wall is removed so that the positioning studs of the wire connecting box in that position slide through the channel, but can not slide through the positioning screws of another wire connecting box at another position; the step edge at the via hole of each connector is configured with respect to the positioning screws at the connecting hole of each retaining seat; in assembly, the stop edge is removed, so that the positioning screws of the wire connecting box in that position slides through the via hole, but can not slide through the positioning stud of another wire connecting box at another position; therefore, the electric connecting structure for a lamp is formed by above components and assembly way, furthermore, in assembly, the lamp rod is inserted into the wire connecting box so that the connector and the retaining seat are connected correctly.
