Press bond terminal and method for pressing and bonding terminal

摘要

An object of the invention is to improve electrical connection performance by increasing a pressure of contact between an electric wire and a terminal. A conductor press bond part (11) of a terminal is formed in substantially a U-shaped cross section opened upward by a base plate (11A) and a pair of conductor crimp pieces (11B, 11B) extended upward from both right and left lateral edges of the base plate (11A). A range from the base plate (11A) to the root of the pair of conductor crimp pieces (11B, 11B) is formed as a curved wall (11H) with substantially a circular arc shape, and when a radius of curvature of an inner surface of the curved wall (11H) is R and a radius of a conductor of the electric wire is r, the curved wall is set so as to satisfy R

主权项

1. A press bond terminal having a conductor press bond part connected by being pressed and bonded to a distal end of a conductor of an electric wire, the conductor press bond part being formed in substantially a U-shaped cross section opened upward by a base plate and a pair of conductor crimp pieces extended upward from both right and left lateral edges of the base plate, the press bond terminal being electrically connected to the electric wire by inserting the conductor of the electric wire between the pair of conductor crimp pieces in the case of being pressed and bonded to the electric wire and inward rounding the pair of conductor crimp pieces to crimp the conductor crimp pieces so as to wrap the conductor with the base plate by a press bond operation of a lower mold and an upper mold of a press bond device in its insertion state,
wherein a range from the base plate to the root of the pair of conductor crimp pieces is formed as a curved wall with substantially a continuously circular arc shape and when a radius of curvature of an inner surface of the curved wall is R and a radius of the conductor of the electric wire is r, the curved wall is set so as to satisfy R
