Background
The shielding effectiveness is an important performance index for measuring the radiation interference and radiation leakage of the shielding cable. Therefore, it is necessary to test the shielding performance of the cable. The wire injection method is a commonly used means for detecting the shielding efficiency of the cable, and at present, a single cable test and a cable test with a connector are already available in a cable test experiment adopting the wire injection method, but the test for the cable with the plug is extremely lacked, and even no one is willing to study how to test the whole shielding effect of the cable with the plug.
The reasons for the above problems are mainly two-fold. Because a length of cable is usually tested in the prior art, and the industry commonly uses such a testing method, it is difficult for a tester to think of connecting a plug to a cable before testing. Secondly, if the plug is connected to the cable and then tested, a testing device with different sockets is used for testing cables with plugs of different specifications, so that the cost is high; moreover, because the test device is usually made of copper, the quality is high, the installation and wiring of the test device are very complicated, and a large amount of time is usually needed for installation and adjustment of the test device, so that the detection efficiency is greatly reduced, and the test personnel generally think that the test device is unnecessary. However, the shielding performance of the cable reaches the standard, and the poor shielding performance of the connection part of the cable and the plug exists, so that the use of other electronic equipment is possibly interfered in the use process of an automobile, and the service life of the equipment is seriously reduced or even potential safety hazards are caused.
