Abstract

An electrical socket includes a sliding rail unit and a receptacle unit disposed slidably on the sliding rail unit. The receptacle unit includes a base and a receptacle seat mounted rotatably on the base. The receptacle seat is rotatable on the base between a conducting position, where the receptacle unit is retained on the sliding rail unit, and a non-conducting position, where the receptacle unit is removable from the sliding rail unit.

Dependent claims

An electrical socket comprising:

a sliding rail unit including a sliding rail seat and two parallel power wires extending along a longitudinal direction of said sliding rail seat, said sliding rail seat having two elongated hollow power wire-mounting walls each defining a mounting space for mounting a respective one of said power wires therein, and two parallel slide slots disposed respectively adjacent to said power wire-mounting walls, each of said power wire-mounting walls being formed with a retaining groove communicated with a corresponding one of said slide slots and a corresponding one of said mounting spaces in said power wire-mounting walls;
and
a receptacle unit disposed above said sliding rail unit and including
a base,
two spaced-apart conducting plates disposed on said base, each of said conducting plates having a wire engaging portion extending into the corresponding one of said slide slots in said sliding rail seat, and a prong-engaging portion disposed above said wire-engaging portion, and
a receptacle seat mounted rotatably on said base and having a top wall that is formed with two power prong-engaging holes, said receptacle seat being disposed at a conducting position, where said power prong-engaging holes in said top wall of said receptacle seat are aligned respectively with said prong-engaging portions of said conducting plates, and where said wire-engaging portions of said conducting plates extend respectively through said retaining grooves in said power wire-mounting walls to contact respectively and electrically said power wires so as to prevent removal of said receptacle unit from said sliding rail unit, said receptacle seat being rotatable on said base to a non-conducting position, where each of said power prong-engaging holes in said receptacle seat is deflected from a corresponding one of said prong-engaging portions of said conducting plates, and where said conducting plates are removed from said retaining grooves in said power wire-mounting walls and said power wires so as to allow for removal of said receptacle unit from said sliding rail unit;
wherein said base of said receptacle unit includes a base wall disposed slidably on said power wire-mounting walls, and an insert rod fixed on said base wall, said receptacle seat being sleeved rotatably on said insert rod;
and
wherein said receptacle seat further includes a rotary button sleeved rotatably on an end of said insert rod of said base and formed with said power prong engaging holes, and a driving block sleeved rotatably on said insert rod of said base and disposed between said base and said rotary button, said driving block being rotatable synchronously with said rotary button about said insert rod of said base and having two opposite pushing surfaces and two opposite non positioning surfaces, a distance between said non-pushing surfaces being smaller than that between said pushing surfaces, said pushing surfaces pressing respectively against said wire engaging portions of said conducting plates when said receptacle seat is disposed at said conducting position, said non-pushing surfaces being aligned respectively with said wire-engaging portions of said conducting plates when said receptacle seat is disposed at said non-conducting position.
