An electrical connector includes a male electrical plug, a female socket, a housing, and a control system. The male electrical plug, which is supplied with power, is electrically connected to the female socket. The housing contains the male electrical plug, the female socket, and a control system. The control system includes a temperature sensor and a transceiver with the temperature sensor sensing a temperature at a location within the housing and the transceiver transmitting a signal representative of the temperature to an alarm device remotely located from the electrical connector. The electrical connector can include one or more switches that are remotely controllable by the alarm device to interrupt the electrical connection between the male plug and the female socket.

An electrical plug provides protection against electrical surges with a replaceable surge protector cartridge that is readily removable and replaceable along an exterior of the plug. Surge protector circuitry in the cartridge can absorb an electrical surge received at the plug from an electrical mains source, and the electrical plug can maintain electrical continuity from plug prongs to an electrical cord both before and after the surge protector has absorbed an electrical surge.

The present disclosure provides an electrical plug including a first temperature detection element and a second temperature detection element. When the processor determines that the temperature of the contact pins is greater than or equal to a temperature threshold according to a first detection signal outputted by the first temperature detection element and a second detection signal outputted by the second temperature detection element, the processor disables the electrical plug to transmit the input power to a load. When one of the temperature detection elements fails, the electrical plug determines whether the temperature of the electrical plug is greater than or equal to the temperature threshold according to the other one of the temperature detection elements. The electrical plug meets the redundant design required for functional safety to avoid unexpected hazards caused by the failure of a single temperature detection element. Therefore, the stability of the electrical plug is enhanced.

A plug adapter includes a housing, a conductive terminal assembly and a phase detection module. The conductive terminal assembly and the phase detection module are installed in the housing. The conductive terminal assembly includes a live conductive member, a neutral conductive member, and an earth conductive member. The live conductive member is integrally formed with a live conductive socket and a live conductive pin. The neutral conductive member is integrally formed with a neutral conductive socket and a neutral conductive pin. The earth conductive member is integrally formed with an earth conductive socket and an earth conductive pin. The plug adapter is not easy to burn out due to overheating.

The present application provides a pass-through plug, including: a first housing, comprising a plurality of sockets; a second housing, configured to be connected with the first housing; and a tamper resistant assembly, trapped between the first housing and the second housing and configured to selectively block the plurality of sockets when the plurality of sockets are not simultaneously operated. The provided pass-through plug can reduce the potential risk of people accidentally inserting conductive objects into the socket holes.
