[0002] A large number of metal wires are arranged on the surface of the circuit board to connect the circuits. However, such metal wires are generally thin. Therefore, as a precision electronic device, the circuit board is easily damaged by electrostatic discharge or impact or friction from external objects.

[0003] The utility model patent with patent authorization announcement number CN 217825483 U discloses a 5G circuit board with a surface metal wire protection structure, including a circuit board, a base is provided at the bottom of the circuit board, and a protection mechanism is provided above the circuit board; the protection mechanism includes a guard plate, a plurality of abutment columns are fixedly connected to the bottom surface of the guard plate, both ends of the guard plate are fixedly connected to a connecting plate, two symmetrical card blocks are fixedly connected to the outer side wall of the connecting plate, a movable seat is provided on one side of the connecting plate, and two symmetrical card slots are provided on a side wall of the movable seat close to the connecting plate.

[0004] However, the above device still has some shortcomings in actual use.
