Description
Technical field
The utility model relates to the servicing unit of power supply product signal testing, particularly relates to a kind of power supply product measurement jig be connected between measuring instrument and power supply product.
Background technology
Improve the common requirements that the power supply product testing efficiencies such as charger are electron trades, at present, under manual hand manipulation's condition, to such as wiring between the electronic device test system comprising power supply product and measuring instrument, record data can not meet the demand that industry is efficiently tested, one-time detection instrument can only test a power supply product, and on replacing power supply product to be measured, there is very large inconvenience, all need repetition and measuring instrument wiring at every turn, cause the working strength of tester very big, work efficiency is low, and the great majority measurement jig be connected between power supply product to be measured and measuring instrument can only be applied to a certain product to be tested specifically at present, the test of other products cannot be applied to, availability is lower, and cannot Timeliness coverage and duplicated record to abnormal conditions, inconvenient to cause investigation when going wrong.
Utility model content
The purpose of this utility model solves measuring instrument to concentrate monitoring in real time, labor intensity of operating staff greatly, the problem that test job efficiency is low and test products is single to can not conveniently realize during power supply product signal testing to the remote computer of test signal.
To achieve these goals, the utility model provides a kind of power supply product measurement jig, be connected between measuring instrument and power supply product and carry out signal testing transmission, comprise MCU single-chip microcomputer, some relays, some connection terminals, stop button, button A, button B, A/B change-over switch and USB communication interface, MCU single-chip microcomputer receives communication signal by USB communication socket, button A and button B starts MCU single-chip microcomputer respectively by A/B change-over switch, stop button stops MCU single-chip microcomputer to run, MCU single-chip microcomputer passes through relay corresponding to button A or button B and connection terminal receives and transmission power supply product signal.
Also comprise hummer, MCU single-chip microcomputer connection control hummer.
Also comprise some supply sockets and/or joint card extender, connect plug or the out splice going splice of power supply product and measuring instrument.
Button A and button B is respectively arranged with pilot lamp.
The beneficial effects of the utility model are the test present situations for power supply products such as current chargers, this measurement jig can realize order or synchronism detection transmission multiple product signal between measuring instrument and power supply product to be measured, improve client's production efficiency, strengthen the convenience of operation, and reduce costs on this basis, whole test transmission only needs the wiring of connection test macro and measurement jig, make determinand power supply product and between measurement jig, be connected easy, support dissimilar charger test, test variety range is larger.
