Hold, in order to prevent the electric shock problem because its attaching plug after electrical equipment shutdown produces with dangerous voltage for a long time, existing electrical equipment will carry out the discharge test of attaching plug usually.In the prior art, the discharge test method of electrical equipment normally draws wire to oscillograph at the power plug head end of electrical equipment, then in the process of electrical equipment work, extract attaching plug, and then the discharge scenario of electrical equipment is detected by non-ripple device, usually, the power plug voltage of electrical equipment was down to the safe voltage of below 36V in 1 second, and it is qualified to be only.But, this kind of the prior art relies on power plug head end to draw wire and relies on staff to extract the discharge test method of attaching plug, operate comparatively loaded down with trivial details, test data is not accurate enough, and is difficult to realize discharge scenario that is complete, that reflect electronic product clearly within the extremely short time.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of operation more simple and accurately, realize can within the extremely short time discharge test box of discharge scenario that is complete, that reflect electronic product clearly.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of discharge test box, comprises insulation box body, and insulation box body one end is provided with attaching plug, and insulation box body is provided with change-over switch, and the insulation box body other end is provided with the first binding clip, the second binding clip, the 3rd binding clip and the 4th binding clip; Described attaching plug has the first conductor wire and the second conductor wire, wherein, the first conductor wire, after change-over switch, is electrically connected with the first binding clip and the 3rd binding clip respectively, second conductor wire, after power switch, is electrically connected with the second binding clip and the 4th binding clip respectively; Described first binding clip and the second binding clip are in order to the plug terminal of clamping connection electrical equipment, and described 3rd binding clip and the 4th binding clip are in order to the oscillographic monitoring terminal of clamping connection.
Described attaching plug also has the 3rd conductor wire, and the 3rd conductor wire is electrically connected with insulation box body earth terminal.
Described insulation box body comprises upper casing and lower casing, and this upper casing and lower casing are screwed connection.
The beneficial effects of the utility model are: one, the utility model have a change-over switch, can complete blocked operation within the extremely short time; What two, the utility model can make the plug terminal of electrical equipment be more prone to is connected to oscillographic monitoring terminal, and accurate and accurate for the figure of whole discharge process is presented on oscillograph; Three, the utility model is easy to connect, easily operates; After four, adopting insulation box body, make discharge test more safe and reliable.
