100b : 클립100b: Clip

본 고안은 음극선관의 마스크 프레임에 인너쉴드(inner shield)를 고정시키는데 사용되는 클립에 관한 것이다.The present invention relates to a clip used to secure an inner shield to a mask frame of a cathode ray tube.

일반적으로, 음극선관의 내부에는 외부의 지자계(地磁界)로부터 전자비임을 보호하기 위하여 인너쉴드가 설치되는데, 이 인너쉴드를 마스크 프레임에 고정시키는 용도로 클립을 사용한다.In general, an inner shield is installed inside the cathode ray tube to protect an electron beam from an external geomagnetic field, and a clip is used to fix the inner shield to a mask frame.

종래에는 제 1 도(a)에 도시된 바와 같이 클립(100a)은 한가닥의 판 스프링으로 형성되어 있다. 이 클립(100a)은 중심을 기준으로 대칭되게 굴곡되고 양단이 대략 V자형으로 지향되어 있다.Conventionally, as shown in FIG. 1 (a), the clip 100a is formed of a single leaf spring. This clip 100a is bent symmetrically about its center and is oriented approximately V-shaped at both ends.

제 1 도 (b)(c)에 도시된 바와 같이 마스크 프레임(12)이 판넬(10)에 고정되어 있으며, 이 마스크 프레임(12) 및 체결되는 인너쉴드(14)의 상응되는 위치에 이 클립(100a)을 체결할 수 있도록 둘레에 다수개의 구멍(12', 14')이 형성되어 있다.As shown in FIG. 1 (b) (c), the mask frame 12 is fixed to the panel 10, and the clip is placed at the corresponding position of the mask frame 12 and the inner shield 14 to be engaged. A plurality of holes 12 ', 14' are formed in the circumference so as to fasten the 100a.

클립을 체결하고자 하는 경우에는 마스크 프레임(12)과 인너쉴드(14)의 구멍(12', 14')을 일치시키고, 클립(100a)의 중앙 만곡부위를 인너쉴드(14)측에서부터 구멍(12', 14')에 끼워 고정한다.When the clip is to be fastened, the holes 12 'and 14' of the mask frame 12 and the inner shield 14 coincide, and the center curved portion of the clip 100a is opened from the inner shield 14 side. ', 14') to fix it.

도면중 미설명 부호 11은 마스크 프레임(12)을 고정시키는 핀, 13은 마스크 프레임(12)에 있는 새도우마스크, 30은 전자총이다.In the figure, reference numeral 11 denotes a pin for fixing the mask frame 12, 13 a shadow mask in the mask frame 12, and 30 an electron gun.

이와 같은 클립(100a)을 사용하여 필요한 부위마다 마련된 구멍(12', 14')을 통하여 마스크 프레임(12)에 인너쉴드(14)를 고정하는 것이다.Using the clip 100a, the inner shield 14 is fixed to the mask frame 12 through holes 12 'and 14' provided for each required portion.

그러나, 상기와 같은 종래의 클립은 인너쉴드를 지지할 수는 있으나, 밀착성이 없어 프레임과 인너쉴드가 견고하게 고정되지 못하였다. 따라서, 클립이 점차 벌어져 인너쉴드의 지자계 차폐 효과가 떨어지는 문제점이 있었다.However, the conventional clip as described above can support the inner shield, but because the adhesion is not firmly fixed to the frame and the inner shield. Therefore, there is a problem that the clip is gradually opened and the geomagnetic shielding effect of the inner shield is inferior.

이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 클립과 인너쉴드간의 체결력을 향상시킬 수 있는 음극선관의 인너쉴드 체결용 클립을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, and an object thereof is to provide an inner shield fastening clip of the cathode ray tube that can improve the fastening force between the clip and the inner shield.

상기와 같은 목적을 달성하기 위한 본 고안은 판스프링을 교차되게 일체로 형성하여 상, 하 좌우 대칭으로 힘을 받을 수 있도록 한 것을 특징으로 한다.The present invention for achieving the above object is characterized in that the plate spring is integrally formed to intersect to receive the force in the up, down, left and right symmetry.

이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 첨부된 예시도면 제 2 도에 도시된 바와 같이 음극선관의 마스크 프레임에 인너쉴드를 고정시키는 클립에 있어서, 클립(100b)이 판스스프링을 십자형으로 일체로 형성되게 된 구조로 되어 있다.The present invention has a structure in which the clip 100b is formed integrally with the leaf spring crosswise in the clip for fixing the inner shield to the mask frame of the cathode ray tube as shown in FIG.

이와 같이 구성된 본 고안에 따른 클립(100b)을 사용하여 제 2 도(다)에 도시된 바와 같이 인너쉴드(14) 및 마스크 프레임(12)의 구멍(12', 14')에 끼워 체결하면, 수평 및 수직방향으로 힘이 분산되어 인너쉴드(14)가 견고하게 밀착되는 효과가 있는 것이다.When the clip 100b according to the present invention configured as described above is fitted into the holes 12 'and 14' of the inner shield 14 and the mask frame 12, as shown in FIG. The force is dispersed in the horizontal and vertical directions so that the inner shield 14 is firmly in close contact.
