Abstract: A communication box includes a box body and a box lid. The box body has an accommodation space therein. The box lid includes a lid body and two engaging members. Upper and lower ends of the two engaging members are detachably connected to the box body. The two engaging members are respectively and pivotally connected two opposing sides of the lid body, so that the two engaging members are rotatable relative to the lid body. Compared the conventional communication box, the communication box of the present invention can be opened in different ways. Through one of the two engaging members, either side of the box lid can be opened. Alternatively, the box lid can be detached from the box body through disengagement of the two engaging members. The present invention can be used in different occasions and is convenient for operation, without limitation of space.

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.
