  • Patent number: 9799996
    Abstract: An assembly of plural conductive slots sharing an overheating destructive fixing element is disclosed, including a first conductive element, a second conductive element and an overheating destructive fixing element. The first conductive element includes a front end, a rear end, plural conductive slots and a contact portion. The conductive slots include a front end conductive slot and a rear end conductive slot, between which a control section is defined. The contact portion is disposed on the control section, and the second conductive element contacts the contact portion by the overheating destructive fixing element, allowing the plural conductive slots to share the overheating destructive fixing element. Furthermore, when any one conductive slot reaches each own limiting working temperature respectively, the overheating destructive fixing element is destructed by reaching a pre-determined temperature.

  • Publication number: 20100210141
    Abstract: The present invention is to provide a socket structure of current-rectifiable lamp string and especially is aimed at a socket set with rectification diodes. Its features are that one pin of the left and right rectification diodes along with wires inside the socket are clamped on the left and right terminals and the other pins are rivet-assembled with one conductive connector to form a mutually conducting status. It thus can solve the problem of inconvenience in constructing caused by the former welding method.

  • Patent number: 7750789
    Abstract: A breaker switch includes a connector housing having plug-in contacts and a socket housing having sockets. The connector housing has a fuse chamber having an opening through which a fuse can be inserted into the fuse chamber. A lever pivotably mounts the housings such that the connector housing is movable with the lever relative to the socket housing between starting and final positions. In the starting position the housings disengage such that the contacts and sockets disengage. In the final position the housings engage such that the contacts and sockets engage. A cover is movably connected to the connector housing to move between opened and closed positions. The cover opens the fuse chamber opening when opened and closes the fuse chamber opening when closed. When the cover is opened the cover prevents the connector housing from moving to the final position thereby preventing the contacts and sockets from electrically connecting.

  • Patent number: 7740504
    Abstract: A power circuit breaker having a simple structure with a small number of components is provided. The power circuit breaker includes: a circuit receiver which receives a pair of circuit terminals connected to an end of an opened power circuit; and a plug body having a fuse to be mounted on the circuit receiver to close the power circuit. In the fuse, a pair of terminals extending from a housing, which receives a fuse element of the fuse, is bent approximately at right angles at the middle of the terminal. A central curving portion of the bent part is provided with a notch. A cross section of the terminal exposed within the notch is pressed by a jig, which fits with the notch, so that the fuse is press-fit into the plug body.

  • Patent number: 7410377
    Abstract: A plug and socket system for electrical coupling of mains power, and safety socket cap devices are disclosed. The devices are an in line plug device FIG. 2 with a removable Semi hollow plug spigot 6 that houses removable electrical pin means 9/10. A wire clamping means FIG. 12/5; is attached to the Semi hollow plug spigot in one embodiment to retain wires to the pin terminals. A locking latch means FIG. 2/7, locks both the socket and the plug together FIG. 1 by a cantilevered latch FIG. 8, which is pushed into the socket and then is held in position by an internal slot inside the socket FIG. 10/9. The latch is released by using leverage with one or more fingers inside a finger hold FIG. 1/4, while depressing a button FIG. 1/3 or series of buttons FIG. 9/2 and the two devices can be separated. A water-resistant seal is created by the inclusion of an ‘O’ ring FIG. 4/11. The Semi hollow plug spigot depth FIG. 3/14 into the socket device and the locking of the two devices creates a tamper proof chamber.
