NOVELTY - The utility model claims a graphene capacitor with over-voltage protection, the binding post comprises a hollow insulating shaft for passing through the circuit board and conductor sleeved in the column body, the conductor passes through the shell to be connected with the graphene electrode, one end of the column body is fixed on the shell, and further provided with a cross fixing bracket at the end; the central position of the cross-shaped fixing bracket is provided with a slide, the slide is sliding connected with sliding rod, one end of the conductive shell is connected with one end of the cylinder opposite to the shell is provided. and there is cylindrical folded outwards at the end, the turnover is the graphene film, the folded part folded outwards after set in a circular ring. The utility model with over-voltage protection of the graphene capacitor by mini electromagnet, sliding sleeve, sliding rod, it can effectively realize that one effect of the over-voltage protection.
