JPS61259438A - Fixing member of internal magnetic shield for cathode-ray tube - Google Patents

Abstract

PURPOSE:To prevent a frame deformation and improve color purity, without processing a transmission hole with high precision, by putting an elastic fitting part, which is formed on one side and inserted into the transmission hole of a fixture, in conformity with the size of the transmission hole of the frame. CONSTITUTION:A fixing member 1 of an internal magnetic shield for a CRT is formed by bending both ends of a strip-shaped copper plate respectively in an assigned shape. A pointed end of one end part 1a fixed at a frame 3 is opened with it turning inside so as to become larger than a transmission hole 6, to support the frame 3, with a clipping part 14 having folding-back strips 12 and 13 of an elastic fitting part 15. A hook part 8 is formed at the end part 1b, for being hung at a side edge of a transmission hole 7 of the inter nal magnetic shield 4. With the hook part 8 of the fixing member 1 being hung at the transmission hole 7, the pointed end of the fitting part 15 is lowered facing the transmission hole 6 of the frame 3, reducing the width so that a slant surface 11 makes contact to the side edge of the passing hole 6, passing through the transmission hole 6, and then restored to the original state with its own elastic force.

ねくことがあるという問題点もあった。In addition, since the mounting member (υ) has a simple shape and the protrusion (2) is small, there is a risk of misreading the direction of the protrusion (2) or using the two pieces overlapped. In this case, the internal magnetic shield (4) may come off the frame (3), and in the latter case, there is a problem in that its shadow may appear on the edge of the cathode ray tube screen.Furthermore,
Internal magnetic shield (4) while pulling the mounting bracket α
Because it is bent at the edge of the through hole (7), the frame (
There is also the problem that the color selection electrode (9) may be locally deformed when a load is applied locally to 3), leading to a decrease in color purity.

ことを目的とする。This invention was made in the ninth attempt to solve these problems, and it does not require high precision in the through holes (6) formed in the frame (3), and it also eliminates the need for deformation of the frame (3) and, ultimately, the color of the frame (3). The object is to obtain a mounting member (1) that does not cause a decrease in purity.

- The end of the frame narrows when it is inserted into the through hole of the frame, and after passing through, it expands with its own elastic force to prevent it from being pulled out, and it also holds the frame from within the through hole. An elastic engagement part is formed with a clip part consisting of two bent sides, and the other end has a
A hook portion is formed to be hung on the edge of the through hole of the internal magnetic shield.

〔作用〕[Effect]

取付金具のフレームの透孔に挿入される一方の側に形成

じて挾まることができるので、フＶ−ムの透孔の大きさ
が高精度であることを要しない。The elastic engagement part formed on one side of the mounting bracket that is inserted into the through hole of the frame can be clamped depending on the size of the through hole of the frame, so that it can be inserted into the through hole of the frame. The size does not need to be highly accurate.

また、フレームの透孔に装着され九ときは、クリップ部

とはない。Further, when the frame is attached to the through hole of the frame, the frame is elastically held by the clip portion from inside the through hole, so that it will not fall off even if a tensile force is applied in the longitudinal direction.

ない。In addition, since the mounting bracket is attached to the frame by the clip, even when the other end of the mounting member is bent at the edge of the through hole of the internal magnetic shield, the tensile stress is alleviated by the elastic force. Therefore, no deformation occurs in the frame, and therefore no deterioration in color purity occurs due to this.

Insert the hook part (8) into the fully transparent hole (7) of 1) and hang it, and while keeping this state, insert the elastic engagement part μ of the mounting member (υ).
When the tip of s faces the through hole (6) of the T frame (3) and is pushed down, the sloped opening υ comes into contact with the side edge of the through hole (6), its width is narrowed, and finally the through hole (6) ) after passing through 9,
It returns to its original shape due to its own elastic force. At this time, the frame (3) and the internal magnetic shield (4) are held between the bent sides UZ and a3 forming the clip portion a4.

ない。In addition, the stress applied to the frame (3) can be reduced by simply applying a small pressure to press fit the elastic engagement part 4 of the mounting member (υ) into the through hole (6), and the elastic engagement part (4) itself can be removed. You can bend it to narrow its width and insert it into the through hole (6).
There is no deformation of the frame (3), and therefore no deterioration of color purity due to deformation of the color selection electrodes.
