  • Patent number: 6616484
    Abstract: A plug has a plug casing, an inner tube received in the plug casing and having two recesses oppositely defined in a top of the inner tube to receive therein a first blade and a second blade, a fuse tube having therein a spring, a fuse retainer with legs extending out therefrom and a fuse. The spring abuts the fuse retainer and the legs securely clamp the fuse. A fuse engaging ring is connected to the fuse tube. A connecting ring is engaged with the inner tube to electrically connect to the first connecting leg of the fuse engaging ring. After the connection of the connecting ring to the inner tube which has the fuse tube, the spring, the fuse retainer and the fuse therein, the fuse electrically connects to the fuse engaging ring and therefore the connecting ring.

  • Publication number: 20020109990
    Abstract: A decorative light plug has a female connector integrally formed on the decorative light and a cover. A flange is formed on an outer periphery of the female connector. The cover has a blind hole defined to enclose a distal end of the decorative light, a pair of keyways formed in the blind hole to correspond to a pair of keys formed on the outer periphery of distal end of the female connector and an annular groove defined to correspond to the flange on the female connector. After the distal end of the decorative light is pressed into the blind hole of the cover, the flange is received in the annular groove. A ring outside the cover facilitates the detachment of the cover from the female connector.
