High-capacity electrical connection structure, linear bus system and right-angle bus system

The invention discloses a high-capacity electric connection structure, a linear type bus system and a right-angle type bus system. The structure comprises a supporting piece, a shielding conductor, a buffer pad, a guide sleeve, a conducting rod and an electric contact assembly. The whole shielding conductor is of a U-shaped structure, and the two ends of the shielding conductor are of chamfer flaring structures. One end of the supporting piece is spliced with the inner surface of the bottom of the U-shaped structure; the connector end of the conducting rod is limited in the inner cavity of the U-shaped structure through the chamfered flaring structure and the other end of the supporting piece; the joint end of the conducting rod is connected with the inner cavity of the U-shaped structure through a buffer pad, a guide sleeve and an electric contact assembly, and the buffer pad is a deformable device; and the guide sleeve is in interference fit with the surface of the inner cavity. Therefore, while the insulat
