摘要： The present invention is the field of electrical elements, related to the technology for improving the connection performance of the static contact device for strong current in high voltage switches, especially for a type of static contact device for strong current in high voltage earthing switches. It includes a base, with two Contact Pieces standing face-to-face on it and vertical to its upper end surface. Outside each of the two Contact Pieces, there is a supporting plate, the lower end of which is firmly fixed on the base. Two groups of coaxially stacking Belleville springs are set between each supporting plate and the contact piece on the same side. By way of setting two groups of Belleville springs on one side, the present invention enlarges the contact surface between the Contact Piece and the moving contact blade, effectively reinforcing the gripping for each other. Compared with the scheme in which a single group of Belleville springs is used on one side with equal pressure, this new scheme can prolongs the products' service life as well as ensure good connection performance of the static contact.
