Description

Technical Field

[0001] The utility model relates to the technical field of testing multifunctional interfaces and the field of financial technology, and more specifically, to an automatic testing device for multifunctional interfaces. Background Art

[0002] As more and more electronic devices are equipped with Universal Serial Bus (USB) multi-function interfaces, in order to ensure that the USB interface can work properly and the hot-swap life of the USB interface, it is necessary to perform a plug-in test on the USB interface during factory inspection.

[0003] In the related art, CN206460108U discloses a multifunctional automated interface test device, which includes a chassis, a drive device and a plug-in mechanism. The chassis is a stepped structure, which is divided into a first step and a second step. The device to be tested is fixed on the first step, and the drive device is arranged in the second step. The drive device includes a motor and a control system. The plug-in mechanism includes a moving column and a transverse plug-in column. The moving column is connected to the motor, a slide groove is arranged on the upper surface of the second step, and the moving column can be slidably arranged in the slide groove. A plug-in head is arranged at one end of the transverse plug-in column, and the plug-in head can be plugged into a test port such as a network port of the device to be tested, so that multiple devices can be plugged in and out at the same time. A display screen and a pause button are arranged on the first side of the second step, and the display screen and the pause button are electrically connected to the control system respectively. An LED light is also arranged on the front side of the first step opposite to the moving column, and the LED light is connected to the control system. The display screen and the LED light have an alarm function when used together. Although the interface testing device in the related technology can replace manual testing of the network port and other test ports of the device to be tested, there is a problem that the plug head cannot be aligned and plugged into the test port of the device to be tested. In the absence of staff to monitor the test process, it is easy for the test port being tested to enter the test of the next test port before reaching the required number of tests, so that the test results of the test port that is not tested normally cannot accurately reflect the actual performance of the test port, thereby reducing the test efficiency.
