Abstract

A common two-prong and three-prong socket AC power receptacle has several sockets that are provided on a top and one side surface on a casing. One end of the casing has a switch. The sockets on the top surface of the casing are three-prong ones and those on the side surface are two-prong. Some sockets are directly connected to a power cord. The others are connected in series to a switch, where the switch can control whether they are on or off. This design can provide users more socket space to use and better controls.

Dependent claims

A common two-prong and three-prong socket AC power receptacle, which comprises:

a casing, which has a top surface, a side surface, a first end, and a second end;
a plurality of three-prong sockets (12) on the top surface;
a plurality of two-prong sockets (14) on the side surface;
a first wire (181);
a second wire (182);
a ground wire (183);
a first electrode plate (20);
a second electrode plate (30);
a third electrode plate (40);
and
a ground plate (50);
wherein the first electrode plate (20), the second electrode plate (30), the third electrode plate (40) and the ground plate (50) are mounted in the casing (10);
the casing (10) has a switch (16) on the first end of the casing and a power cord (18) extending from the second end of the casing, some sockets (12, 14) are directly connected to the first wire (181) and the second wire (182) in the power cord (18), respectively, and therefore provide power all the time, and the others are connected with the switch (16) in series with one leg of the circuit, and whether or not they provide power is thus controlled by the switch (16);
the first electrode plate (20) comprises a plurality of clip contact sets (22) at positions corresponding of the sockets, the first electrode plate (20) being connected between the first wire (181) in the power cord (18) and the switch (16);
the second electrode plate (30) is formed with a plurality of clip contact sets (32) at positions corresponding to some of the sockets, the second electrode plate (30) being connected between the second wire (182) of the power cord (18) and the switch (16);
the third electrode plate (40) comprises a plurality of clip contact sets (42) at positions corresponding to some of the sockets, the third electrode plate (40) being connected with the switch (16);
and
the ground plate (50) is formed with contacts (52) at positions corresponding to ground holes in the three-prong socket sets (12) and is connected with a ground wire (183) in the power cord (18).
