Thus, after the male plug 300 is located in the limiting groove 601, the cylinder 5 can be controlled (specifically, a control button of the cylinder is pressed, for example, an expansion rod in the cylinder is controlled to move up or down), so that the press block 52 moves upward by a predetermined stroke, and the male plug 300 in a state of being separated from the electrical connection sheet 61 is pressed upwards to be attached to the electrical connection sheet 61, thereby realizing electrical connection of the male plug and the female plug.
Since there is a certain angle (about 45 degrees) between the flexible circuit board 200 and the display screen 100 in a suspended state due to gravity, it is preferable that the angle between the guide channel 401 and the test panel 31 is 30-45 degrees. Thus, it is advantageous for the operator to put the flexible wiring board 200 into the guide passage 401, and the putting process is simplified as much as possible.
By combining the above embodiments, the utility model abandons the original structure of inserting during testing, realizes the electric connection between the male plug and the female plug through the electric connecting sheet in a fitting mode, so as to increase the loading and unloading speed of the male plug and the female plug during testing, and sets two detection areas to be detected on one testing panel, and the testing of two screens to be detected can be alternately completed in one detection period, thereby increasing the continuity of the testing and greatly improving the testing speed.
