Abstract
An electrical male plug for use with an electrical double outlet comprising two sets of prong-receiving sockets respectively connected in pairs to a same electric power source. The plug has two sets of prongs that are positioned to respectively engage at the very same time the two sets of prong-receiving sockets of the double outlet. The prongs of the two sets of prongs are electrically connected in pairs to a same electrical conductor that may be part of a high power-consuming appliance. In use, the electrical load supported by each of said prongs when theplug is used is divided by two.

ELECTRiCAL MALE PLUG
BACKGROUND OF THE INVENTION
a) Field ot the invention Tho present invention relates to an electrical male plug for use with an electrical double outlet. More particularly, the invention relates to an electrical male plug ~;ull l,ul i~il ,g two sets of prongs that are connected to the same conductor and are positioned to engage at the very same time the two set of prong-receiving sockets of the double outlet so as to split in two the current circulating through each of said prongs and thus to reduce the risk of accident due to overheating when the load connected to the conductor is hi3her than the one that can be supported by one set of prongs engaged into one set of prong-receiving sockets of the electrical double outlet exclusively.
b) Brief des~,. . . of the prior ar~
A great number of electrical domestic ~,u~ such as water kettles, mobile bd~ JUdld heaters, toasters and the like are known to draw a great amountof power supplied by the AC wall outlets to which they are connected. Therefore,high currents flow across the electrical cu,~ uliu, Ib between these d,UUI;dl ,~ and 2 o the electrical supply wiring whose maximum supply capacity is often almost reached.
The effects of these high currents are particularly noticeable at the level of the prongs of the appliance plug when these prongs are plugged into the ~u" ~ ul~dil ,y sockets of the AC wall outlet. It has been ~Ap~ "~.l that non-negligible heat is generated within the plug and adjacent outlet, such a heat being perhaps caused by the illlp~dd"ce in the ",e~;l,d"i~al contacts between the prongs and the sockets. Such a heat might prove damaging to the sockets of the wall outlet and to the appliance plug, without l"~"`i lill9 the potential danger of fire or shock.
