Patent number: 6568942Abstract: An electric appliance has a body member and a detachable electric cord. The body member includes a connecting portion having at least one pin member extended therefrom. The electric cord includes at least a first plug member and a second plug member which are electrically connected with each other. The first plug member is electrically connectable to an electric source. The second plug member is releasably engageable with the connecting portion of the body member by a magnetic attracting force between them. The pin member includes a tapered end surface, and the second plug member includes at least one aperture sized to receive the pin of the connecting portion of the body member. The width of the aperture is greater than the width of the pin member by a factor in the range of 1.1 to 5.Type: GrantFiled: February 9, 2001Date of Patent: May 27, 2003Assignee: Eastern Sources Housewares (Hong Kong) LimitedInventors: Wing Chung Joseph Lau, Leung Chi Ho
