CONDUCTOR CONNECTION STRUCTURE AND SWITCH GEAR USING SAME

摘要

A conductor connection structure in electric device bus connection application, or the like, wherein a connection surface (4a) of one conductor (4) and a connection surface of another conductor are brought together and fastened with a fastening member using a through-hole (5) provided on each of the connection surfaces. The conductor connection structure is constituted such that a circular or polygonal groove (7) concentric to the through-hole (5) is formed on the connection surface (4a) of one conductor (4) by embossing, and a protrusion (6) is formed due to bulging of material from the groove (7). When the two conductors are fastened, the protrusion (6) is in line-contact with the connection surface of the other conductor.
