ABSTRACT:
A structure is provided by a welding method of connecting a connection terminal piece to lead wires extending from a deflection yoke coil for deflecting electron beams. The lead wires are led out from a winding body and consist of one or more conductive cores each of which has a coating layer of a self fusing layer and a high thermal-resistance insulation layer therearound. The welding method includes the steps of burning and eliminating said self fusing layer and said high thermal-resistance insulation layer of said lead wires from said conductive cores by heating through a burning method, and fusing and solidifying a filler metal wherein said filler metal is disposed between said connection terminal piece and said lead wires and has conductive and adhesive properties. The burnt materials of said self fusing layer and said high thermal-resistance insulation layer are extracted out of said lead wires during said burning and eliminating step. The fused and solidified filler metal fills the spaces between said conductive cores and said connection terminal piece, thereby welding said conductive cores and said connection terminal piece.
