  • Terminal joining structure and terminal joining method
    Patent number: 8235735
    Abstract: A terminal joining structure includes a terminal having a tubular barrel portion and a flange portion that is integrally formed at the axis-direction end of the barrel portion, a conductor substrate on which is opened a through-hole for inserting the barrel portion, and a ring that fits on the barrel portion on the opposite side of the conductor substrate. On the barrel portion is formed a taper that increases in diameter toward the flange portion. The diameter of the larger-diameter portion of the taper is larger than the inner diameter of the through-hole. The terminal is caulked to cause radially outward expansion of an end part of the barrel portion, which passes through the ring, on the opposite side of the conductor substrate and is fixed to the conductor substrate together with the ring.
