Abstract: An electronic device with a plug guard that can be connected to an external power source and other digital source respectively by a power plug and a digital data plug and has an electronic device and a plug guard. The electronic device has an outer surface and an integrated external interface socket. The integrated external interface socket is formed in the outer surface and has a power segment and at least one digital data segment formed in-line and communicating with each other. The plug guard is mounted securely on the outer surface of the electronic device adjacent to the digital data segments to keep the power plug from being plugged into the digital data segment.

Abstract: An auxiliary device for a connector has a body, a wire unit and plug. The wire unit is mounted securely in the body and extends out of the body from a first end of the body. The plug is formed on a second end of the body and is perpendicular to the wire unit. Therefore, the position of the wire unit is fixed when the plug is inserted into a socket.

Abstract: An electrical connecting assembly has an electrical appliance and a connector. The electrical appliance has at least one surface, a positive electrode plug and a negative electrode plug. The plugs are mounted separately on the surface. The connector connects to the electrical appliance and has two electrical wires and an anti-error sheath. The electrical wires respectively have a positive electrode socket and a negative electrode socket. The positive and negative electrode sockets connect respectively to the positive and negative electrode plugs. The anti-error sheath connects to one of the sockets and has a socket sheath with mounting key protruding longitudinally from the socket sheath. The mounting key ensures that the socket on the wire on which the anti-error sheath is connected can only be plugged onto the correct plug.
