ンバンド４を巻きつけ固定することにより防爆陰
極線管が形成される。 Explosion-proofing of cathode ray tubes is carried out after the electron gun is sealed in the valve, then exhaust aging is performed, and the tube is completed. That is, as shown in Figure 1,
An uncured thermosetting adhesive or adhesive tape is wrapped around the outer periphery of the panel 1 constituting the front part of the cathode ray tube envelope, and then a steel rim band 3 to which the steel lug 2 is welded is attached to the lug 2. are arranged so as to correspond to each corner of the rectangular panel 1, and are wound and attached onto the adhesive or adhesive tape sown, and a steel tension band 4 is further wound on top of this rim band. By attaching and fixing, an explosion-proof cathode ray tube is formed.

めて固定することもある。 Winding and fixing of the tension band is generally performed as follows. A rim band with lugs is placed on top of the adhesive or adhesive tape wrapped at a predetermined position around the panel's periphery, and then the drum of a tension band feeder is rotated to the outside of the rim band to supply this material. Wrap the steel tension band supplied from the drum, hold the tip of the tension band set in place with a holding plate, and then rotate the drum of the tension band feeder in the opposite direction to release the rim band. A predetermined tension is applied to the tension band wrapped around the outside. With tension applied in this manner, the feeder drum side of the tension band wound around the outside of the rim band is fixed using another tension band holding plate. Next, the feeder drum side is cut off using a tension band cutter, and both ends of the tension band wound around the outside of the rim band are welded using a welding device. Instead of welding both ends together, fixing metal fittings may be caulked to secure the ends.

すればよいが、板厚を厚くするとコストが高くな
るという問題がある。 When installing a steel tension band in this manner, if the drum of the feeder is reversely rotated to apply tension to the tension band, friction will occur between the tension band and the lug and rim band, resulting in a loss of tension. In particular, the lugs have an acute angular shape and protrude from the rim band, so friction is large and causes a large loss of tension, making it impossible to apply a predetermined tension. If the tension band is pulled further to apply sufficient tension, the tensile strength of the band will be exceeded and the band will break. In order to improve this problem, the thickness of the plate can be increased, but there is a problem in that increasing the thickness of the plate increases the cost.

That is, the present invention is characterized in that a lug-equipped rim band having a self-lubricating surface is used, and a tension band is wound and fixed onto the lug-equipped rim band.
以下本発明を実施例について説明する。 The present invention will be described below with reference to Examples.

Using a resin molded rim band with lugs made of nylon resin integrally molded with the The lugs 11 are arranged so as to correspond to each corner of the panel, and a steel tension band is supplied from the drum of a tension band feeder and wrapped around the rim band with lugs in the same manner as in the conventional method. It was fixed under tension.

を行つたが、不合格となるものはなかつた。 In this way, an explosion-proof cathode ray tube using a lug-equipped rim band resin molded body made of nylon resin has a tension of 580 kg when using conventional steel lugs and rim bands. The tension could be increased to 650Kg.
This is interpreted to be because the resin molded rim band with lugs made of nylon resin has excellent self-lubricating properties. It was able to provide a sufficient explosion-proof effect, and 100 pieces were subjected to the specified impact test, and none failed.

ある。 Note that the rim band resin molded body with a ram, which is formed by integrally molding the lugs and the rim band described above, not only has self-lubricating properties on the surface around which the tension band is wound, but also has the ability to withstand the pressure caused by the tension band attached thereon. The material must be sufficiently durable. It is also necessary to maintain sufficient mechanical strength to hold the valve. In addition to the above, examples of such materials include linearly polymerized nylon, MoS 2 -filled nylon, graphite nylon, glass fiber nylon, Teflon, tetrafluoroethylene resin, phenolic resin, ceramic-containing fluororesin, vinyl chloride, polyester, polyacetal, etc. is suitable. Furthermore, in the past, the lugs and rim band were formed by cutting and forming a steel plate, plating, and then welding the lugs and rim band, but if the above-mentioned materials are used, they can be easily formed as one piece, and the process Another advantage is that it simplifies the process.

る。 In this way, the explosion-proof cathode ray tube of the present invention is provided with a lug rim band whose surface is self-lubricating, which reduces friction with the tension band that is wrapped around and fixed on the rim band. Therefore, it is possible to obtain an explosion-proof cathode ray tube that can sufficiently prevent implosion and has good characteristics.
