(57) A compact rotary power supply plug corresponding to 200 V of the European and U.
S. standards and formed with reduced number of parts into a simple structure can be
provided. A plug supporting piece (10) is pivotably provided on one end of an insertion
plug storing recess (3) provided at a surface of a housing (1). Insertion plugs (11,11)
made of a metal conductive material are supported at the plug supporting piece (10)
and projected therefrom. A contact (19) in electrical connection with each insertion
plug (11) is provided at the bottom surface (10b) of the plug supporting piece (10).
Each contact (19) is contacted to a connection terminal (20) in the housing (1) when
the plug supporting piece (10) is upraised together with the insertion plugs (11,
11). The insertion plugs (11, 11) are pushed down together with the plug supporting
piece (10) and stored into the recess (3). The housing (1) includes a housing main
body (1a) and a housing lid body (1b) fitted with one another, half bodies (12b, 12b)
of bearings (12, 12) provided on both sides of the recess (3) for rotatably supporting
the shaft (10a, 10a) of the plug supporting piece (10), projection pieces (13, 13)
for the bearings on both sides of the main body and the other half bodies (12a, 12a)
of the bearings provided at the tip ends of the projection pieces (13, 13). The plug
storing recess (3) is provided at an outer surface of the lid body (1b). The housing
main body (1a) is fitted with the lid body (1b) for joining both half bodies of the
bearings to form the bearings (12, 12).
