Abstract:
1. An electric connection device for electrically connecting an electrical appliance to a power source, comprising: a live wire connecting unit having a live wire plughole and including a live wire connection terminal electrically connected to said live wire plughole; a neutral wire connecting unit having a neutral wire plughole and including a neutral wire connection terminal electrically connected to said neutral wire plughole; a ground wire connecting unit having a ground wire plughole and including a ground wire connection terminal electrically connected to said ground wire plughole; an electric circuit arrangement comprising a live wire access terminal and a neutral wire access terminal; and a control unit adapted to be shifted between an idle state and an activation state, whereby in said idle state, said live wire connecting unit and neutral wire connecting units are not connected to the power source and, in said activation state, said control unit electrically connect said live wire connecting unit and said neutral wire connecting unit to the power source, so as to electrically connect an electric circuit between said electric connection device, the power source and the electrical appliance, wherein said control unit comprises: a push member extending into said ground wire plughole; two micro-switches arranged in such a manner that when said live wire plughole, said neutral wire plughole and said ground wire plughole respectively receive three plug pins of the electrical appliance until the three plug pins are respectively electrically connected to said live wire connection terminal, said neutral wire connection terminal and said ground wire connection terminal, said control unit is in said activation state that said push member is arranged to be pushed by one of the three plug pins which is received in said ground wire plughole to switch on said two micro-switches to electrically connect said live wire connection terminal with said live wire access terminal, and to electrically connect said neutral wire connection terminal with said neutral wire access terminal respectively, so as to electrically connect said electric circuit between said electric connection device, the electrical appliance and the power source, wherein when said control unit is in said idle state, even though said live wire plughole and said neutral plughole respectively receive the plug pins and the plug pins are electrically connected to said live wire connection terminal and said neutral wire connection terminal respectively, said live wire connection terminal and said neutral wire connection terminal are not electrically connected to said live wire access terminal and said neutral wire access terminal of said electrical circuit arrangement; and a reposition arrangement adapted to switch off said two micro-switches of said control unit when the plug pin of the electrical appliance is removed from said ground wire plughole, wherein said live wire connection terminal and said neutral wire connection terminal are electrically disconnected with said live wire access terminal and said neutral wire access terminal respectively.
