本考案は小型陰極線管のフアンネルに関するも

ている。(Prior Art) The cone of the funnel constituting the cathode ray tube is made of glass, and the anode terminal (commonly known as an anode button) is attached by making a hole in the middle of the funnel. Recently, small cathode ray tubes have come to be used as viewfinders in video cameras, and in pursuit of making them smaller and lighter, attempts are being made to make the cone of the funnel out of metal.

しまうからである。(Problems to be Solved by the Invention) FIG. 2 is a side view showing part of a cathode ray tube using a funnel whose cone portion is made of metal. 1 is a funnel cone, 2 is an anode terminal, and 3 is a panel with a phosphor attached.
The cone part 1 of the funnel and the anode terminal 2 are joined by resistance welding, laser welding, beam welding, etc., but the work is difficult because the joint part is slanted, and the cone part is thin. Power adjustment management was difficult. This is because if the power is too low, there will be insufficient bonding force, and if the power is too high, holes will form.

The cone portion 11 of the funnel is formed by press working from a plate material. The choice between deep drawing or burring depends on the material of the funnel plate, the processing method after processing, etc.
Since this is not the main point of this invention, it will be omitted. A flange portion 11a for joining the panels is formed on the cone portion 11 of the funnel, but in this embodiment, the anode terminal portion 4 is integrally formed with the flange portion 11a.
was formed. FIG. 3 is a side view of a funnel in which a panel 3 is joined with a seal member 5 to the embodiment shown in FIG. The anode terminal portion has been bent, and its appearance is almost the same as the conventional example shown in FIG.

There are no longer any quality issues associated with this. Of course,
The equipment required for joining work is no longer required, and funnels can now be manufactured easily, inexpensively, and with consistent quality.
