Abstract

Purity convergence adjustment magnet structure of the present invention has a radius of the spacer between the 2-pole and 4-pole magnet in order to prevent the glue or paint applied to the 2-pole magnet from flowing into the 4-pole or 6-pole magnet. Since it is larger than the four-pole magnet to prevent the inflow of the glue or paint applied to the two-pole magnet to the four poles, the problem of landing failure due to the inflow of the glue or the like.

The present invention relates to a magnet structure for adjusting the purity convergence of a color brown tube, and in particular, a silicon structure for adjusting the purity convergence that prevents the silicone or paint used for fixing the adjusted purity magnet from entering the convergence magnet. It is about.

As shown in FIG. 1, the conventional magnet structure 10 includes a pair of ring-shaped two-pole 12, four-pole 13, and six-pole magnets 14, and a ring-shaped shape interposed between the pairs. The magnets and spacers are mounted on the outer circumferential surface of the spacers 15, the magnet holder 11 to which the magnets and the spares are mounted on the outer circumferential surface, and the inner circumferential surface thereof is inserted into the CRT neck portion, and the magnets and the spacers are axially oriented. Rocker 16 to be secured by a screw, a band 17 to fix the holder 11 to the neck portion, and a screw 18.

A pair of two-pole magnets 12 of the magnet structure is called a purity magnet for landing modification, and a pair of four-pole and six-pole magnets 13 and 14, respectively, are used to concentrate the electron beam at the center of the screen. This is called a convergence control magnet.

The 2-pole magnet 12 needs to be fixed after the purity adjustment is finished, while the 4-pole 6-pole and the magnets 13 and 14 should be disassembled to allow for later convergence adjustment on the TV maker side. do. Conventionally, in order to fix the two-pole magnet 12, the two-pole magnet 12 is fixed, and then a silicone, paint, or the like is coated on a predetermined portion of the two-pole magnet 12, so that paint, silicon, etc. Firm to fix the two-pole magnet (12). However, since it is difficult to paint only the two-pole magnet 12 accurately, it may be possible to paint up to four or six-pole magnets 13 and 14, and silicon or paint painted on the two-pole magnet 12 may be four-pole or six-pole. It flows up to the pole magnets (13) and (14) and is fixed not only to the two pole magnets (12) but also to the four or six pole magnets (13) and (14), so that four or six poles can be adjusted for future convergence. The magnets 13 and 14 were shocked to free the 4-pole or 6-pole magnets 13 and 14. At this time, there is a problem in that landing failure occurs because the purity control is incorrectly impacted by the two-pole magnet 12 that is accurately adjusted to the purity.

An object of the present invention is to provide a magnetic structure for adjusting the purity convergence that can prevent the silicon or paint applied to the two-pole magnet to be introduced into the four-pole or six-pole magnet to solve the above problems.

As a means for achieving the above object, the purity structure of the magnet for adjusting the convergence according to the present invention is a silicon or paint painted on the two-pole magnet by making the radius of the spacer between the two-pole and four-pole magnet larger than the two-pole and four-pole magnet It is characterized by preventing the inflow into the four poles.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a side view showing a state in which the purity convergence structure is coupled according to the present invention. As shown, the purity convergence magnet structure according to the present invention is provided between the two-pole magnet 12 and the four-pole magnet 13. The radius of the spacer 20 is larger than the radius of the two-pole magnet 12 and the four-pole magnet 13 is formed. The dipole magnet 12 is coated with fixing means 21 made of silicon, paint, or the like after the purity adjustment is completed. Unexplained reference numerals in the drawings are the same as those of the conventional structure for adjusting the purity convergence, so that description thereof is omitted.

As shown in FIG. 3, the structure for adjusting purity convergence according to the present invention is configured to fix the dipole magnet 12 while the fixing means 21 of silicon, paint, etc. painted on the dipole magnet 12 is hardened. Since the spacers 20 having a larger radius than the two-pole magnets 12 and the four-pole magnets 13 are interposed therebetween, the fixing means 21 such as silicon and paint are four-pole or six-pole magnets 13 (14). In addition to being prevented from entering), the worker can eliminate the worry of painting not only the 2-pole magnet 12 but also the 4-pole or 6-pole magnet 13 and 14.

As described above, the magnetic structure for adjusting the purity convergence of the present invention solves the problem of landing failure due to the inflow of the fixing means such as the glue into the four-pole and six-pole magnets, and it is more preferable for the operator to paint only the two-pole magnet. It has an effect of facilitating.
