PRESSURE BONDING TERMINAL, CONNECTION STRUCTURE, AND METHOD FOR MANUFACTURING CONNECTION STRUCTURE

摘要

The purpose of the present invention is to provide a pressure bonding terminal, a pressure bonding connection structure, and a manufacturing method for a pressure bonding connection structure that are capable of avoiding pressure bonding cracking during pressure bonding and capable of stabilizing pressure bonding resistance. The present invention is characterized by: a barrel part (200) that allows pressure bonding connection of an aluminum core wire (101) exposed at the tip of a coated wire (100), which is coated by an insulating coating (102), being formed in a cylindrical shaped by bending a location for the barrel part in a terminal base material with a terminal extending shape around the terminal axis; a welding part (230b) to which an end part (230a) is welded to the end part (230a) faced by the location for the barrel part being formed along the longitudinal direction (X) of the coated wire (100); and the welding part (230b) being formed on an upper surface recessed part (234a) and a protruding part (234T), which have an amount of deformation larger than other parts in the circumferential direction of a conductor pressure bonding part (232) when the conductor pressure bonding part (232) undergoes plastic deformation with the pressure bonding of the conductor pressure bonding part (232).
