  • Publication number: 20100124849
    Abstract: In one embodiment, an electrical box can comprise: a container formed from a base having sides extending therefrom to define a cavity; a cover configured to cover the cavity when in a closed position; and a female electrical connector disposed in the cavity when the cover is in the closed position. A socket of the female electrical connector can be capable of receiving a male electrical connector. Even when the electrical box is connected to live wiring, when the cover is in an open position, current cannot flow to the socket, and when the cover is in a closed position, current can flow to the socket. In another embodiment, an electrical box can comprise: a container; a cover configured to cover the cavity when in a closed position; and a female electrical connector physically connected to the cover such that the female electrical connector moves as the cover is opened.

  • Publication number: 20090218131
    Abstract: In an embodiment, a conduit connector can comprise: a body comprising a box engagement region capable of engaging an opening in an enclosure and a spring configured to engage the connector and the enclosure. The box engagement region can have a root surface, a leading tab, and a follower tab wherein the root surface and leading tab can be located between a leading edge and a secondary edge. A leading tab perimeter edge and a follower tab perimeter edge define a tab perimeter diameter that is larger than an opening in the enclosure. When the leading tab is inserted into the enclosure the spring can be disposed to engage the secondary edge and the enclosure.
