본 고안은 음극선관용 전자총의 핀조립체에 관한 것으로, 특히 듀메트선이 스템에 매입되는 핀조립체의 내부도입선에 판상선단부를 형성하여 전자총 전극조립체를 구성하고 있는 지지편과의 용접성을 양호하게 하는 동시에 전극조립체와 스템의 접속강도를 안정되게 유지할 수 있도록 한 음극선관용 전자총의 핀조립체에 관한 것이다.The present invention relates to a pin assembly of an electron gun for a cathode ray tube, and in particular, a plate-like tip is formed on an inner lead of a pin assembly in which a dumet wire is embedded in a stem, thereby improving weldability with a supporting piece constituting the electron gun electrode assembly. The present invention relates to a pin assembly of an electron gun for a cathode ray tube, which can stably maintain the connection strength between an electrode assembly and a stem.
일반적으로 음극선관용 전자총은 그 전형적인 형태를 제1도에서 보인 바와 같이, 비드글라스(1)에 의하여 음극지지체(2), 제1 및 제2그리드 전극(3)(4), 제3 및 제4그리드전극(5)(6)이 착설되고 음극선 지지체(2)의 하측에는 다수개의 지지편(7)이 착설되어 스템(8)에 고정된 내부도입선(9)이 용접으로 접속되어 있다. 그리고, 이 내부도입선(9)은 제2도 및 제3도에서 보인 바와 같이 핀조립체(10)의 일부를 구성한다.In general, an electron gun for a cathode ray tube, as shown in FIG. 1, has a cathode support (2), first and second grid electrodes (3) (4), third and fourth by a bead glass (1). Grid electrodes 5 and 6 are mounted, and a plurality of support pieces 7 are mounted below the cathode ray support 2, and an internal lead wire 9 fixed to the stem 8 is connected by welding. The inner lead wire 9 constitutes a part of the pin assembly 10 as shown in FIGS. 2 and 3.
즉, 핀조립체(10)는 외부도입선(11), 직경이 작은 듀메트선(12)과 상기 언급된 내부도입선(9)으로 구성되며 모두 봉상의 형태로 되어 있고 듀메트선(12)의 부분이 스템(8)에 매입 고정된다. 그리고 봉상의 내부도입선(11)은 지지편(7)에 대하여 봉상의 두 용접전극에 의하여 스폿트 용접된다.That is, the pin assembly 10 is composed of an outer lead line 11, a small diameter demetr line 12 and the aforementioned inner lead line 9, all of which are in the form of rods and are part of the demetr line 12. It is fixed to this stem 8 embedded. And the rod-shaped inner lead wire 11 is spot-welded by the rod-shaped two welding electrodes with respect to the support piece 7.
그러나 이러한 핀조립체(10)에 있어서는 내부도입선(11)의 선단을 지지편(7)에 봉상의 용접전극으로 용접하기에는 매우 번거러우며 내부도입선(11)의 중심을 안정되게 가압하는 것이 어려워 용접불량의 원인이 되기도 한다. 따라서 내부도입서(11)과 지지편(7)의 접속상태가 불량하게 하거나 용접스플라쉬가 발생하게 되는 문제점이 있다. 내부도입선(11)과 지지편(7)의 접속상태가 불량하면 전극지지체와 스템(8)이 정렬되지 않고 경사져 결국 전자짐이 음극선관의 축과 경사지게 발사되어 찌그러진 빔스포트를 형성함으로써 음극선관의 해상도를 크게 저하시키는 원인이 되며, 용접 스플라쉬의 발생은 전극간의 방전을 유발하여 음극선관에 치명상을 줄 수 있는 요인이 된다.However, in such a pin assembly 10, it is very cumbersome to weld the tip of the inner lead wire 11 to the support piece 7 with a rod-shaped welding electrode, and it is difficult to pressurize the center of the inner lead wire 11 stably, resulting in poor welding. It can also cause. Therefore, there is a problem in that the connection state between the internal guide 11 and the support piece 7 is poor or a welding splice is generated. If the connection between the inner lead wire 11 and the support piece 7 is poor, the electrode support and the stem 8 are not aligned and are inclined so that the electron baggage is inclined with the axis of the cathode ray tube to form a crushed beam spot. The resolution is greatly reduced, and the generation of a welding splice causes a discharge between the electrodes, which causes a fatal wound on the cathode ray tube.
본 고안에 있어서는 종래의 이와 같은 점을 감안하여 안출한 것으로, 내부도입선의 선단에 판상선단부를 형성하여 지지편에 대한 용접이 양호하고 안정되게 이루어질 수 있도록 한 것인 바, 이를 제1도, 제4도 및 제5도에 관련하여 보다 상세히 설명하면 다음과 같다.In the present invention, in view of such a conventional point of the present invention, a plate-like tip portion is formed at the tip of the inner lead wire to be welded to the support piece can be made good and stable, this is shown in FIG. More detailed description with reference to FIGS. 4 and 5 are as follows.
비드글라스(1)에 의하여 음극지지체(2)와 제1-제4그리드 전극(3)(4)(5)(6)이 착설되고 음극선지지체(2)의 하측에 다수개의 지지편(7)이 착설되어 스템(8)에 고정된 핀조립체(10)의 내부도입선(9)이 용접으로 접속되게한 것에 있어서, 내부도입선(9)의 선단에 판상선단부(20)를 형성하여 판상의 지지편(7)에 용접으로 접속되게 하여서된 구조이다.The bead glass 1 installs the cathode support 2 and the first-fourth grid electrodes 3, 4, 5, and 6, and a plurality of support pieces 7 below the cathode support 2. In this installation, the inner lead wire 9 of the pin assembly 10 fixed to the stem 8 is connected by welding, and a plate-shaped support piece is formed by forming a plate-shaped tip portion 20 at the tip of the inner lead wire 9. It is a structure made to be connected to (7) by welding.
이와 같은 본 고안은 스템(8)에 매입고정된 핀조립체(10)의 내부도입선(9)을 지지편(7)에 용접시 그 판상선단부(20)가 지지편(7)과 같이 판상으로 되어 있어 봉상의 용접전극으로 안정되게 가압할수 있으므로 용접상태가 양호하게될 수 있고 용접된 기계적인 강도가 충분히 유지될 수 있어 전자빔의 진로를 변경시키지 아니하며 용접스프라쉬의 발생을 크게 줄일 수 있는 이점이 있는 것이다.The present invention is such that the plate tip 20 is plate-like like the support piece 7 when the inner lead wire 9 of the pin assembly 10 embedded in the stem 8 is welded to the support piece 7. Since it can be stably pressurized by the rod-shaped welding electrode, the welding state can be improved, and the welded mechanical strength can be maintained sufficiently so that the course of the electron beam is not changed and the generation of welding splash can be greatly reduced. It is.
