In line terminals, control unit determines the actuation and disconnection of relay according to the connected state of detection switch.This structure is used and opened
The state of test plug is closed, when plug is inserted into, promotes connecting key to make access terminal and picks out terminal conducting, when plug is extracted, bullet
Property component reset connecting key, disconnect access and terminal and pick out terminal, i.e., realize that plug detects by mechanical movement, existing can not
The problems such as leaning on, reporting by mistake.
The Chinese invention patent application of Publication No. CN103236613A discloses a kind of power outlet, each by being arranged on
Range sensor at group jack carries out ranging in real time, then is according to the corresponding breaker of testing result control by control module
It is no to work, to ensure the power supply safety of power outlet.This device due to need set range sensor, it is complicated,
It is of high cost, meanwhile, range sensor needs to carry out ranging in real time, is constantly in working status, both waste of energy, also have impact on makes
With service life and use reliability.
Accordingly, it is desirable to provide a kind of power outlet simple in structure, reliable operation with plug detection function, to adapt to
The work requirements of various power control systems.
The content of the invention
