ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electron gun assembly for a color picture tube, and more particularly to a welding and fixing structure between a cathode support eyelet and a cathode support eyelet support structure.
一般、同一平面内において、３個のカソードを

FIG. 1 shows a cross-sectional view of a conventional in-line integrated electron gun assembly, particularly the G 1 electrode and the cathode portion, and FIG. 2 shows the cathode portion as seen from the G 1 electrode side of FIG. 1.

レツト４Cを２点の溶接により固定されている。 In these figures, 1 is a G 1 electrode, 2 is a G 1 electrode support, 3 is a cathode system, 4 is a cathode support eyelet, and 5 is a cathode support eyelet support, and the cathode support eyelet 4 is approximately connected to the cathode support eyelet 4. It is held at the center, and both ends thereof are embedded and fixed in bead glass 6. Incidentally, the subscripts C and S of each reference symbol indicate a center electron gun and a side electron gun, respectively. Furthermore, as shown in these figures, conventionally the cathode support eyelets 4 C and 4 S that support the cathode systems 3 C and 3 S , respectively, are
The cathode support eyelet support structures 5 C and 5 S are welded and fixed at the parts indicated by the cross marks, and in particular, the central electron gun is held between the two cathode support eyelet support structures 5 C , and the cathode support eyelet 4 C is fixed by welding at two points.

等により、容易に発生するという欠点があつた。 However, according to the electron gun structure having the above configuration, as shown in FIG. 3, the cathode support eyelet support structure 5C is deformed into the shape shown by the solid line, as opposed to the design specification of the shape shown by the dotted line. In other words, this shape deformation occurs due to thermal stress during welding and the bead glass 6 and side support eyelet 4 during logistics such as transportation of the electron gun assembly.
There is a drawback that unnecessary external force is applied to the cathode support eyelet support 5S and the cathode support eyelet support 5S, and this force is easily generated due to stress deformation caused by concentration on the cathode support eyelet support 5C .
したがつて本発明は、上記従来の欠点を解決し

However, detailed explanation will be omitted. In Figures 4 and 5, the central cathode support eyelet 4C
The two cathode support eyelet supports 5 C1 and 5 C2 that support and fix the cathode support eyelet 4 C are curved portions 5 C that tightly sandwich the circumferential surface of the cathode support eyelet 4 C.
1 ′ and 5 C2 ′ have different curved surface lengths, and in particular are formed so that the curved portion 5 C1 ′ is short and the curved portion 5 C2 ′ is long, and this cathode support eyelet support body 5 C1 , 5 C2 The arm portions 5 C1 ″ and 5 C2 ″ are configured to face each other and come into close contact with each other. and,
The cathode support eyelet 4 C is welded and fixed to the cathode support eyelet support 5 C1 ′ within the curved part 5 C1 ″ at the part indicated by the cross mark, and the cathode support eyelet supports 5 C1 and 5 C2 are in close contact with each other. An electron gun is constructed by welding and fixing the part between the arm parts 5 C1 '' and 5 C2 '' shown by an x.
