Abstract

A lamp holder having two ribs perpendicularly raised from the periphery thereof at two opposite sides, and two smoothly arched clamping plates respectively connected to the ribs, the smoothly arched clamping plates each defining with the periphery of the lamp holder two clamping holes at two opposite sides of the ribs for holding a respective lead wire.

Claims

1. A lamp holder for a decorative light string comprising:

a) a lamp holder base having an opening to accept a lamp bulb therein, the lamp holder base having a circular cross-sectional configuration with a convexly curved outer surface;

b) first and second longitudinal ribs extending radially outwardly from diametrically opposite sides of the lamp holder base, each rib having a distal end; and

,

c) an arcuate clamping plate on the distal end of each rib, each arcuate clamping plate extending beyond opposite sides of the associated rib in a circumferential direction so as to form with a portion of the convexly curved outer surface of the lamp holder base, two clamping holes opening in opposite circumferential directions, each configured to clamp a wire of the light string therein.

2. The lamp holder of claim 1 further comprising a convexly curved entrance portion formed on each opposite circumferential side of each arcuate clamping plate, the convexly curved entrance portions bounding, with the convexly curved outer surface, openings of the clamping holes.
