6c is not shown).
そして、バンド２に一体に爪？ａ、７ｂ、７ｃ、７ｄを
設け、ここに消磁コイル８ａ、８ｂを取付けるようにし
ている。And the claws on Band 2? a, 7b, 7c, and 7d are provided, and degaussing coils 8a, 8b are attached thereto.
この装置は消磁コイル８ａ、８ｂを用いているので消磁
効果は良いが、消磁コイル８ａ、８ｂは高価であるので
カラーテレビのコストに大きな影響を与える。Since this device uses degaussing coils 8a and 8b, the degaussing effect is good, but since the degaussing coils 8a and 8b are expensive, they have a large impact on the cost of the color television.
そこで本考案は消磁コイルを除去し、代りに陰極線管の
前面部を磁気遮蔽しようとするものであり、以下本考案
の一実施例について図面を参照して説明する。Therefore, the present invention eliminates the degaussing coil and instead attempts to magnetically shield the front portion of the cathode ray tube.One embodiment of the present invention will be described below with reference to the drawings.
第２図、第３図、第４図に示すようにエスカッション９

１４ ａ、 １４ ｂ。Escutcheon 9 as shown in Figures 2, 3 and 4.
4 bosses 1°at 10b on the cathode ray tube mounting part,
10c and 10d, the cathode ray tube 11 is attached to the iron band 12, and the mounting pieces 13a and 13b of this band 12 are attached.
, 13c, 13d (13c is not shown) with screws 14a, 14b.
１４ｃ、１４ｄによってボス１０ａ、１０ｂ、１０ｃ、
１０ｄに固定できるようにする。Bosses 10a, 10b, 10c, by 14c, 14d,
It can be fixed at 10d.
上記４本のボス１０ａ、１０ｂ、１０ｃ、１０ｄの内側
になるようにエスカッション１の後面にリング状のリブ
１５を猛威する。A ring-shaped rib 15 is provided on the rear surface of the escutcheon 1 so as to be inside the four bosses 10a, 10b, 10c, and 10d.
このリブ１５の相対向スる部分の間隔はエスカッション
１の前方に行くほど少し狭くなるようにリブ１５の内壁
が傾斜して構成されている。The inner wall of the rib 15 is configured to be inclined so that the distance between the opposing portions of the rib 15 becomes slightly narrower toward the front of the escutcheon 1.
このリブ１５の内壁に当接するようにリング状の磁気遮
蔽体１６を設ける。A ring-shaped magnetic shield 16 is provided so as to come into contact with the inner wall of this rib 15.
磁気遮蔽板１６は硅素鋼板等の高透磁率材料によって作
られる。The magnetic shielding plate 16 is made of a high magnetic permeability material such as a silicon steel plate.
リブ１５に磁気遮蔽体１６を押し込むと、磁気遮蔽体１
６は弾力性があるので押し込むほどしつかりとリブ１５
に固定される。When the magnetic shield 16 is pushed into the rib 15, the magnetic shield 1
6 is elastic, so the more you push it in, the more firmly the rib 15
Fixed.
上記バンド１２に一体に突片１７ａ、 １７ｂ、１７
ｃ、 １７ｄを設け、ボス１０ａ、１０ｂ、１０ｃ、
１０ｄにバンド１２を取付けたとき、この突片１７ａ〜
１７ｄが磁気遮蔽板１６の後端に当るので、磁気遮蔽板
１６はバンド１２とエスカッションの間に固定される。Projecting pieces 17a, 17b, 17 are integrated with the band 12.
c, 17d, bosses 10a, 10b, 10c,
When the band 12 is attached to 10d, these projecting pieces 17a~
17d corresponds to the rear end of the magnetic shielding plate 16, so the magnetic shielding plate 16 is fixed between the band 12 and the escutcheon.
バンド１２を前方の方へ延長して磁気遮蔽板とすること
も考えられるが、バンドは強度の点から鉄で作られるの
で、磁気遮蔽効果が少なく実用的でない。Although it is possible to extend the band 12 toward the front and use it as a magnetic shielding plate, since the band is made of iron from the viewpoint of strength, the magnetic shielding effect is small and is not practical.
以上のように本考案によれば消磁コイルを用いずにリン
グ状の磁気遮蔽体を用いるのでコストが安くつくもので
あり、磁気遮蔽体の取付けに際しビス等を用いる必要が
ないので製造の作業性も良いものである。As described above, according to the present invention, the ring-shaped magnetic shield is used without using a degaussing coil, so the cost is low, and there is no need to use screws when attaching the magnetic shield, which improves manufacturing workability. is also good.
