Power supply expansion structure with socket and plug and power supply expansion device

Abstract

The invention provides a power supply expansion structure with a socket and a plug. The power supply expansion structure with the socket and the plug mainly comprises a circuit board, a plug unit, a socket unit, a fuse unit and a protection unit. The plug unit and the socket unit are arranged on two opposite faces of the circuit board, and the fire wire terminal, the neutral line terminal and the earth terminal of the plug unit and the fire wire jack assembly, the neutral line jack assembly and the earth jack assembly of the socket unit are correspondingly arranged and electrically connected. The protection unit is arranged on the socket unit in a covered mode and provided with a movable blocking door used for shielding the socket unit. In addition, the invention further provides a power supply expansion device with the power supply expansion structure. The power supply expansion structure can accord with socket / plug specifications and safety standards of British standards, is combined with the circuit board to provide circuit configuration with an extended function at the same time, and simplifies electric conduction or circuit configuration of internal electrical connection.

Description

[0001] technical field [0002] The invention relates to a power expansion structure and a power expansion device, in particular to a power expansion structure and a power expansion device with a socket and a plug. Background technique [0003] In the known technology, the types of power connectors include independent sockets, independent plugs, power adapters, expansion power supply units that increase the number of sockets, or expansion power supply units with integrated functions; wherein, independent sockets and independent plugs are used between different devices or The electrical connection between the device and the power supply for power supply or power transmission; the power adapter usually has a plug for connecting to an AC power socket, combined with another socket of another specification to convert the input power to the voltage and / or output after current conversion; the expansion power supply device used to increase the number of sockets has a plug for conne...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned known power connectors, the independent socket and the independent plug only have the function of single power output or input; while the power adapter with both socket and plug structure and the expansion power supply device with increased number of sockets are only for power supply applications, and applications that do not have other additional extended functions; in addition, extended power supply devices with integrated functions, such as power line network devices, are plugged into indoor AC power outlets to provide their extended functions. Most of the extended power supply devices do not There are additional sockets, so the use of the original AC power socket is limited; in addition, the expansion power supply device combined with the socket and plug structure takes up a lot of space on the circuit board due to the socket and plug configuration, resulting in the device being unable to The miniaturization and the limitation of the space for laying out the circuit on the circuit board, and the wiring configuration of the electrical correspondence between the socket and the plug structure are complicated, which is not conducive to the reduction of processing and assembly and manufacturing costs
