7. A manufacturing method of a circuit board structure for preventing high-frequency signals from leaking is characterized by comprising the following steps:

the method comprises the following steps: when a high-frequency signal leaks, the chip (2) controls the output power of the electron (81) to be reduced until a magnetic field generated by current flowing through the coil (85) is reduced, so that the current of the electron (81) passing through the coil (85) is reduced, the magnetic field generated by the iron core (84) is reduced, when the magnetic field is reduced, the magnetic force generated by the iron core (84) cannot adsorb the black iron (88), the black iron (88) can rotate upwards under the action of the tension spring (89), when the black iron (88) rotates upwards, the black iron is limited by the limiting column (810), the upward movement distance is limited, so that the black iron (88) can be adsorbed by the electrified coil (85) and the iron core (84), when the black iron (88) is separated from the upper part of the iron core (84), the rotation can rotate around the fixing pin (87), and when the fixing pin (87) rotates, the end of the black iron (88) far away from the fixed pin (87) is driven to rotate upwards;

step two: when the black iron (88) rotates, the rotating pin (912) and the connecting rod (913) can be pulled upwards to move upwards until the black iron (88) abuts against the limiting column (810), when the rotating pin (912) and the connecting rod (913) move upwards, as the side wall of the connecting rod (913) is abutted with the guide block (914), the guide block (914) can play a guiding function on the movement of the connecting rod (913), when the connecting rod (913) moves, the connecting rod (913) can pull the moving rod (91) to move downwards in the moving groove, when the moving rod (91) moves downwards, the moving rod (91) can drive the first push head (93), the first push head (93) can be separated from the side wall of the second push head (94), and after the second push head (94) is separated from the extrusion of the first push head (93), the first push head (93) can drive the fixing rod (95) to move downwards until the second push head (94) is connected with the connecting head (96) through the fixing rod (95), and the connecting head (96) can be separated from each other Separating, so that no signal is transmitted between the contact head (96) and the connecting head (98), thereby achieving the function of breaking and interrupting the signal output;

step three: after the chip (2) controls the coil (85) to be electrified, the coil (85) generates a magnetic field through the iron core (84) so as to attract the black iron (88) downwards, when the black iron (88) moves downwards, the black iron (88) can push the movable pin (911) and the connecting rod (913) to move downwards, the fixed pin (87) and the connecting rod (913) are attached to the side wall of the guide block (914) to rotate downwards, therefore, the movable rod (91) can be pushed to move, the movable rod (91) can drive the first pushing head (93) to move when moving, the first pushing head (93) can jack the second pushing head (94) to move upwards when moving, the second pushing head (94) can push the fixed rod (95) to drive the connector (98) to move upwards until the connector (98) is attached to the contact head (96), thereby enabling the two contacts (96) to be connected to a signal by the connector (98).
