본 고안은 음극선관의 마스크 프레임에 관한 것으로, 특히 게터 지지스프링 용접시 정확한 위치에 용접할 수 있도록한 구조를 가진 마스크 프레임에 관한 것이다.The present invention relates to a mask frame of a cathode ray tube, and more particularly to a mask frame having a structure that can be welded in the correct position when the getter support spring welding.

현재 사용되고 있는 음극선관용 마스크 프레임에는 게터 지지스프링의 용접부를 마킹한 상태에서 작업자가 이미 마킹한 부위에 게터스프링을 마스크 프레임에 용접하여 부착하였다.In the mask frame for cathode ray tubes currently used, the getter spring was welded to the mask frame and attached to a portion already marked by the worker while marking the welded portion of the getter support spring.

이러한 종래의 기술은 마스크 프레임에 게터 지지스프링 용접시, 위치 변동이 발생하여 고주파 유도가열에 의한 게터플레싱(Flashing)때 고주파 코일 위치와 게터의 위치가 불일치하게되어 게터플레싱처리가 안되는 경우가 종종 발생되는 문제점이 있었다.In this conventional technique, when the getter support spring is welded to the mask frame, a position change occurs, and when the getter flashing by the high frequency induction heating occurs, the position of the high frequency coil and the getter does not match and the getter flashing process is not performed. There was often a problem that occurred.

따라서 본 고안은 전술한 문제점을 해소하기 위하여 안출된 것으로, 그 목적은 마스크 프레임의 게터 지지스프링 용접부위를 정확하게 셋팅하여 게터 지지스프링을 정확한 위치에 간단하게 용접할 수 있도록하여 고주파 코일과 일치되도록하는 음극선관용 마스크 프레임을 제공하는 것이다.Therefore, the present invention has been devised to solve the above-mentioned problem, and its purpose is to accurately set the getter support spring welding part of the mask frame so that the getter support spring can be simply welded to the correct position to match the high frequency coil. It is to provide a mask frame for a cathode ray tube.

이와 같은 목적을 달성하기 위하여 본 고안은 판넬 내부에 끼워지는 마스크 프레임에 있어서, 프레임의 좌우 절곡면에 결합부를 형성하여 게터 스프링을 절곡된 용접면에 삽입하여 용접할 수 있도록 구성되는 음극선관용 마스크 프레임을 제공함에 그 특징이 있다.In order to achieve the above object, the present invention is a mask frame that is fitted inside the panel, the mask frame for the cathode ray tube configured to be welded by inserting the getter spring into the bent welding surface by forming a coupling portion on the left and right bent surface of the frame It is characterized by providing.

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

첨부된 예시도면 제 1 도 내지 제 2 도에서 알 수 있는 바와 같이 마스크 프레임(20) 후부의 절곡면 좌우측에 결합부(21)를 형성하되, 결합부(21)가 마스크 프레임(20)의 절곡면에 턱을 이루도록하는데, 이는 게터스프링(30)의 절곡된 용접면과 결합부(21)가 일치되도록 형성한 다음 판넬(10)의 내면부에 마스크 프레임(20)을 결합하고, 마스크 프레임(20)의 후부 절곡면에 형성된 결합부(21)에 게터스프링(30)의 절곡된 용접면을 삽입하여 스폿용접한다.As shown in FIGS. 1 to 2, the coupling parts 21 are formed on the left and right sides of the rear face of the mask frame 20, and the coupling parts 21 are bent in the mask frame 20. It forms a jaw on the surface, which is formed so that the bent welding surface of the getter spring 30 and the coupling portion 21 coincides with the mask frame 20 to the inner surface of the panel 10, the mask frame ( The bent welding surface of the getter spring 30 is inserted into the coupling portion 21 formed at the rear bent surface of 20 to perform spot welding.

이상에서 설명한 바와 같이 본 고안은 마스크 프레임에 부착되는 게터의 부착위치를 절곡형성하므로 게터스프링의 부착위치 설정이 용이하며 스폿용접시 게터 스프링의 위치가 어긋나지 않으므로 고주파 코일의 위치와 게터의 위치가 정확히 일치되어 게터 플레싱의 효과를 향상시킨다.As described above, the present invention bends the attaching position of the getter attached to the mask frame, so that the setting position of the getter spring can be easily set, and the position of the getter spring is not misaligned during spot welding. Match to improve the effect of getter fleshing.
