Ground.
Described detection backshank end is provided with the round platform big compared with shank.
Solve above-mentioned second technical problem, the technical solution used in the present invention is:
One kind is judged between crimp plug and electric energy measuring equipment binding post when being tested using described crimp plug
The crimping detection method of contact condition, is characterized in that: comprise the following steps:
After electric energy measuring equipment runs to detection station, ejection module promotes push pedal so that detection pin is moved to s1, detection
Pin keeps the accuracy in direction in insulation fairlead slide inside；
During ejection module promotes detection pin mobile, the longer detection pin in pencil center first touches electric energy meter to s2
Amount appliance terminal；Ejection module continues to push away forward, after detection pin top is to electric energy measuring equipment binding post, can compress
Spring, until ejection operation terminates；
After s3 ejection detection pin, read the input port i of microprocessor2, i3…inLevel signal；If these inputs
Mouth reads high level, shows binding post also good contact of its corresponding detection pin and electric energy measuring equipment；
