Efficiently, the contact engaging and separating force of safe and accurate test multi-core electrical connector becomes a urgent problem.
There are many method in relation to the test of electric connector contact engaging and separating force domestic at present, and Chinese patent 201510251268.7 describes
The shortcomings that a kind of high-tension switch cabinet Mume flower contact plug force checking device and its experimental method, the device is only to single contact
Contact engaging and separating force is detected, and is only applicable to the detection of the larger contact contact engaging and separating force of size.201410490368.0 He of Chinese patent
Chinese patent 201210147855.8 describes plug force test device, but both complicated, and cost of manufacture is high, can only be right
The contact engaging and separating force of single plug-in unit is tested, and clamping is cumbersome every time, inefficient.Chinese patent 201510257895.1 is situated between
The electric connector contact that continued plugs characteristic tester, which can measure curve of the contact engaging and separating force with change in displacement well, but
It installs, operate contact engaging and separating force more complicated, and that single plug-in unit can only be tested.
