ABSTRACT:
A safety electric connector includes a main housing, a first plug and a second plug. The first and second plugs are in two different types and can be extended or retracted. The main housing has a chamber therein and a pair of socket holes formed on a top surface thereof. The main housing comprises two first conductive arms, two second conductive arms, two switching members and two connecting members therein. The connecting members and the switching members can be connected or disconnected. One of the plugs is moved to switch the switching member for controlling disconnection/connection of the connecting members and the switching members. Accordingly, the plug which is extended alone has a normal converting function. When both the plugs are pushed out simultaneously, only one plug has the converting function and the other plug doesn't conduct electricity. Therefore, the present invention can avoid any electric shock accidents when both plugs are pushed out, ensuring the safety of the connector when in use.
