[0022] As Figure 1As shown, the wiring device adopts a box type structure, and the front panel of the box mainly has two interfaces: the on-board cable input / output upper interface 2 and the on-board cable input / output lower interface 3. The main function is to install the wiring device between the on-board device and the on-board cable, and to terminate the on-board cable to the on-board cable input / output upper interface 2. The on-board device is connected to the on-board cable input / output lower interface 3 by using the test equipment connection cable 4, so as to realize the unified access of the interaction signals between the on-board device and the on-board cable into the wiring device, and then the next step of carding, testing or excitation.

[0023] As shown in Figure 2 , the core wire positioning test end on the rear panel of the box is composed of a core wire terminal seat 5, a core wire definition plate 6 and a core wire terminal 7. The box body includes a device box fixing seat 8, which can stably fix the box on the installation platform. The signals that need to be tested or excited in the test process are led to the core wire terminal seat 5 printed with the core wire definition number after being processed by the box. The core wire definition number clearly marks the specific definition of the signal, such as pin number, so that the tester can quickly locate it. The core wire terminal seat 5 is equipped with a three-way structure and a core wire terminal 7 that can be quickly plugged and unplugged. When the signal is a bus signal, an oscilloscope or other test resources can be externally connected to locate the signal characteristics.

During the test, there are reserved signals between the on-board device and the on-board cable that do not need to be tested. At this time, the on-board device and the on-board cable are connected through the direct connection signal line channel 11. The signals that need to be tested are respectively sent to the signal carding module 13 through the bus test channel 9 and the discrete signal line channel 10 for bundling and classification processing. The processed signals are sent to the on-board cable input / output lower interface 3 through the on-board cable input / output channel 12, and are respectively sent to the corresponding core wire definition plate 6 through the discrete quantity test / excitation wire harness channel 14 and the bus test wire harness channel 16.
