AI Technical Summary
In cars or motorcycles, the flexible circuit board of the display screen and the motherboard printed circuit board are connected through a connector. If the relative position of the two cases vibrate and cause displacement, the flexible circuit board is prone to twist and break due to rigid connection or the connector falls off the motherboard, resulting in reduced connection reliability.
A circuit board that prevents falling off is designed. By opening a left buffer groove and a right buffer groove on the left and right sides of the flexible circuit board, and penetrate from the upper surface to the lower surface, the printed circuit board and the flexible circuit board are displaced or deformed at the buffer groove, while the connector does not displace, thereby avoiding falling off.
It effectively prevents the connector from falling off the printed circuit board, improving the product's connection reliability and competitiveness.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.
[0034] See also Figures 1 to 4, a circuit board for preventing falling off provided by the utility model comprises a printed circuit board 1 and a flexible circuit board 2, a first connecting device 3 is arranged on the upper surface of the printed circuit board 1, a second connecting device 4 is arranged on the lower surface of the flexible circuit board 2, the first connecting device 3 is connected to the second connecting device 4, a left buffer groove 21 is opened to the right on the left side of the flexible circuit board 2, a right buffer groove 22 is opened to the left on the right side of the flexible circuit board 2, the left buffer groove 21 and the right buffer groove 22 are both penetrated from the upper surface of the flexible circuit board 2 to the lower surface, that is, the left buffer groove 21 and the right buffer groove 22 are both penetrated from the top to the bottom or from the bottom to the top, so that the flexible circuit board 2 can be bent and deformed at the left buffer groove 21 and the right buffer groove 22.
