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.

Terminal joining structure and terminal joining method

A method for manufacturing CRT interior parts made of material such as of iron or steel has the steps of: introducing hydrocarbon and air into a conversion furnace, thereby producing an exothermic gas; cooling the exothermic gas to a predetermined temperature higher than a dew point of the exothermic gas; and introducing the exothermic gas at a temperature higher than the dew point into a blackening furnace which houses the CRT interior parts, thereby producing a blackened film on a surface of each of the CRT interior parts. The blackened film is mainly consisting of Fe.sub.3 O.sub.4. The temperature of the exothermic gas, when introduced in the blackening furnace, may be higher than a boiling point of each component composing the exothermic gas.
