A plug fixing structure is applied to fixing a power plug inserted into a power socket of an electronic device. The power plug has a plug portion and a main body portion. A first engaging structure is formed on an outer periphery of the power socket. The plug fixing structure includes a sleeve casing jacketing the main body portion to expose the plug portion and a first resilient arm having a first arm portion and a first front hook. The first arm portion protrudes from an outer surface of the sleeve casing. The first front hook extends from the first arm portion toward the first engaging structure. The first front hook is engaged with the first engaging structure when the plug portion is inserted into the power socket along a first axis, so as to constrain movement of the power plug along the first axis relative to the power socket.

An electrical extension cord device having an electrical port at one end and an electrical connector at an opposite end. The electrical port can include a cap or cover removable connected to the electrical port having an electrical plug or receptacle. The cap or cover and the electrical port have cooperating sealing surfaces to ensure watertight or waterproof sealing when the cap or cover is installed “on” the electrical port to prevent water or moisture reaching the plug.

An electrical port device having an electrical port and a cap or cover removable connected to the electrical port having a plug. The cap or cover and the electrical port have cooperating sealing surface to ensure a tight waterproof sealing when the cap or cover is installed on the electrical port to prevent water or moisture reaching the plug.

The present subject matter relates to Alternating Current (AC) inlet units. An AC inlet unit includes a socket to receive a power supply cord and a ground pin and a second pin, each disposed in the socket. The AC inlet unit further includes a lead connected to the second pin. The lead is disposed farther from the ground pin as compared to the second pin.

An alternating current/direct current input device includes an appliance input socket and an information and communications technology (ICT) device. The ICT device is powered by the appliance input socket. The appliance input socket includes a ground contact, a positive electrode contact, a negative electrode contact, and a signal switch. A contact depth of the signal switch in the appliance input socket is less than a contact depth of the positive electrode contact or the negative electrode contact in the appliance input socket. The signal switch is configured to generate a control signal when a direct current connector is separated from the appliance input socket. The control signal can be used to enable the ICT device to disconnect the appliance input socket from a conductive electrode of the direct current connector after the ICT device enters a no load state.

The invention relates to a travel adapter, comprising a housing, at least one receptacle of a first standard and at least one plug of a second standard. The receptacle of the first standard has at least one first contact socket and one second contact socket. The plug of the second standard has at least one first contact pin and one second contact pin. The plug is arranged on the housing. The receptacle is rotatably mounted in the housing. The plug or the first contact pin and the second contact pin are pivotally arranged on the housing in such a way that the plug or the first contact pin and the second contact pin can be pivoted out of the housing. The invention also relates to a set and an additional travel adapter.
