Abstract
A male terminal cap and a female terminal cap are mounted on the two ends of a strip light shade to form an extensible strip light shade. Electrical contacts are formed in the terminal caps for electrical coupling when two light shades are connected through mechanical coupling of the terminal caps.
Claims12
An extensible light shade, comprising:
- a first light shade, having a first end and a second end;
- a male terminal cap, mounted on said first end, and having a male fastener and a first metal contact located at a periphery of said male fastener, said first metal contact having a first planar contacting surface;
- and
- a female terminal cap, mounted on said second end, and having a female fastener and a second metal contact located at a periphery of said female fastener, said second metal contact having a second planar contacting surface;
- whereby said male fastener of said first light shade is rotatably insertable into a female fastener of a second light shade at a predetermined angle for locking engagement therewith, said male fastener of said light shade thereby fastens with said female fastener of said second light shade, and a metal contact located at a periphery of said female fastener of said second light shade mechanically contacts and electrically connects with said first metal contact of said first light shade;
- a third metal contact, mounted in said male terminal cap, and wherein the first and third metal contacts surround the male fastener;
- and a fourth metal contact, mounted in said female terminal cap, and wherein the second and forth metal contacts surround said female fastener.
