[0002] During the factory test of the generator set control box (or diesel engine control box), the automatic test equipment needs to be connected to the control box to be tested. In the past, the tester manually connected the test wires on the automatic test equipment to the corresponding wiring terminals of the control box to be tested one by one. After the test, they need to be removed one by one. In the wiring process, the wrong position connection often occurs. In addition, there are many models of control boxes to be tested. It is difficult to avoid the situation of wrong line number position connection if the tester relies entirely on manual wiring.

[0003] Although application number 201721185508.9 provides a controller pin docking device, including a PLC controller, a base, an aluminum profile support, a needle bed, a sliding guide rail, a pneumatic solenoid valve and a cylinder, the test object is different. During the test, the controller to be tested needs to be placed above the needle bed, and the docking device does not limit the controller to be tested, and the stability is poor.
