Description
Technical field
The utility model belongs to plug and socket of power source measuring technology, particularly relates to a kind of signal pickup assembly of plugs and sockets plug number of times proving installation.
Background technology
For electrical equipments such as plugs and sockets, need to carry out plug experiment, with the serviceable life of test plug socket, now existing special automatic plug testing apparatus is carried out, in test process, need to gather plug number of times and add up, prior art mainly through the current and voltage signals when Real-time Collection plug switches on power by AC-DC conversion after directly deliver to controller, carry out counting by controller to process, but after the long plug of plugs and sockets, when causing the two contact owing to loosening, current/voltage is connected and can be produced the contour low-frequency disturbance of spark instantaneously, even produce strong peak current, the accuracy having had a strong impact on controller counting produces miscount, even burn out the input port of controller.
Summary of the invention
The technical problems to be solved in the utility model: the signal pickup assembly that a kind of plugs and sockets plug number of times proving installation is provided, to solve current and voltage signals when prior art Real-time Collection plug switches on power by directly delivering to controller after AC-DC conversion, carry out counting by controller to process, but after the long plug of plugs and sockets, when causing the two contact owing to loosening, current/voltage is connected and can be produced the contour low-frequency disturbance of spark instantaneously, even produce strong peak current, the accuracy having had a strong impact on controller counting produces miscount, even burn out the problems such as the input port of controller.
Technical solutions of the utility model:
A kind of signal pickup assembly of plugs and sockets plug number of times proving installation, it comprises plug turn-on voltage collection terminal and controller input port, plug turn-on voltage collection terminal is connected with voltage reduction module wire, voltage reduction module is connected with rectification module wire, rectification module is connected with filtration module wire, filtration module is connected with shaping circuit wire, and shaping circuit is connected with controller input port wire.
Filtration module is RC filtering circuit.
The beneficial effects of the utility model:
After plug turn-on voltage gathers by the utility model, after step-down rectifier, filtering is carried out by filtering circuit, low-and high-frequency interference in elimination signal, eventually pass the signal that shaping circuit obtains the use of applicable controller, signal stabilization after rectifying and wave-filtering is reliable, solve current and voltage signals when prior art Real-time Collection plug switches on power by directly delivering to controller after AC-DC conversion, carry out counting by controller to process, after the long plug of plugs and sockets, when causing the two contact owing to loosening, current/voltage is connected and can be produced the contour low-frequency disturbance of spark instantaneously, even produce strong peak current, the accuracy having had a strong impact on controller counting produces miscount, even burn out the problems such as the input port of controller.
accompanying drawing illustrates:
