Patent ID: 7172439

Claim:
A DVD integrated CRT television having a main substrate to which a connector can be mounted, the DVD integrated CRT television comprising: a sub-substrate formed with respect to a same work substrate of high fire-resistant material of which the main substrate is formed, the sub-substrate being separated from the main substrate by cutting the work substrate after forming of the substrates; a holding substrate provided between the main substrate and the sub-substrate in the work substrate, and formed in the same manner as the main substrate and the sub-substrate, the holding substrate being separated from the main substrate and the sub-substrate by cutting the work substrate after the forming of the holding substrate and the main substrate, and the holding substrate having a printed surface including an indicator which indicates properties of a raw substrate formed by causing the holding substrate as well as the main substrate and the sub-substrate to be subjected to silk screen printing; connector pins including substantially cylindrical standing-up portions having substantially fixed diameters to which the connector coupled to a degaussing coil provided around a CRT can be fitted on, substantially cylindrical press-fitting portions having substantially fixed diameters and the lengths larger than at least two times a thickness of the work substrate, and flange portions provided between the standing-up portions and the press-fitting portions and having diameters larger than those of the standing-up portions and the press-fitting portions; substantially square-shaped pin holes formed in the holding substrate so as to have intervals between opposite sides thereof which are smaller than diameters of the press-fitting portions and so as to have diagonal lengths larger than the diameters of the press-fitting portions, the press-fitting portions being inserted through the substantially square-shaped pin holes from the side of the printed surface until the flange portions are abutted against the holding substrate; through-holes formed in the main substrate, the press-fitting portions projecting from the holding substrate being inserted through the through-holes so as to penetrate from the side of a component-mounted surface of the main substrate to the side of a pattern surface of the main substrate in such a manner that the surface of the holding substrate which is opposite to the printed surface of the holding substrate comes into close contact with the component-mounted surface of the main substrate; and pads formed on the pattern surface of the main substrate and capable of being soldered to the press-fitting portions penetrating the pattern surface.
