ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an electrical socket, more particularly to an electrical socket having a plurality of receptacle units that are coupled together and that are independently rotatable relative to each other.
2. Description of the Related Art
FIG. 1
illustrates a conventional electrical socket
1
that can be mounted on a stake
10
for outdoor use. The electrical socket
1
includes a housing that is composed of two housing halves which are coupled together, and three receptacle units
12
that are mounted in the housing and that respectively have outlets
121
aligned along a length of the housing for receiving power plugs. A switch
13
is mounted on the housing, and is electrically connected to the receptacle units
12
and an electric wire
14
. A bottom opening
112
is formed in the housing. The stake
1
includes a cone-shaped body
101
and an engaging flange
102
which projects from a top end of the cone-shaped body
101
through the bottom opening
112
and into the housing to engage a periphery of the bottom opening
112
.
Since the outlet
121
in the receptacle units
12
are disposed along a line, it is relatively inconvenient to plug different power plugs that come from different directions. Moreover, the periphery of each outlet
121
tends to accumulate dirt after being in use for a period of time.
SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to provide an electrical socket that is capable of overcoming the drawbacks described above.
Accordingly, an electrical socket of this invention comprises: a pair of insulative housings coupled together, at least one of the housings being turnable relative to the other one of the housings about an axis, one of the housings being formed with a socket outlet that is adapted to receive a power plug; a conductor set including a pair of spaced apart conductors that are mounted in one of the housings and that are adapted to connect electrically with the power plug; a conductive contact member set including a pair of spaced apart contact members that are selectively mounted in one of the housings; and a conductive resilient member set including a pair of spaced apart spring members that are selectively mounted in the other one of the housings, and that respectively and resiliently bridge the contact members, at least one of the resilient member set and the contact member set being rotatable relative to the other one of the resilient member set and the contact member set about the axis with the spring members respectively and resiliently in sliding contact with the contact members when the associated one of the housings rotate relative to the other one of the housings about the axis.
