본 고안은 비데오카메라의 뷰파인더등에 사용되는 초소형음극선관용 전자총의 직열형음극 구조체에 관한 것으로서 특히, 히이터의 저항값의 용이한 한편 히이터의 이상변형(異狀變形)에 의한 히이터의 위치변동이 극소화 될 수 있도록 지지체의 설치구조가 개량된 것에 관한 것이다.The present invention relates to a direct-cathode cathode structure of an electron gun for an ultra-small cathode ray tube used in a viewfinder of a video camera. In particular, the heater's resistance value is easily minimized while the heater's positional variation due to the abnormal deformation of the heater is minimized. The installation structure of the support is improved so that it can be.

저소비전력으로 출화시간이 매우 짧은 일반적인 직렬형 음극 구조체는 제 1 도에 도시된 바와 같이 전자방사물질(50)이 직접 부착되는 W형의 히이터(40)와, 히이터(40)를 그 양단에서 지지하는 한쌍의 지지체(20a)(20a)를 하부에서 몰입파지하여 그 위치를 고정시키는 인슐레이터(10a)등으로 구성된다.In general, the series-type cathode structure having a very short firing time with low power consumption supports the W-type heater 40 to which the electron-emitting material 50 is directly attached, and the heater 40 at both ends thereof, as shown in FIG. And an insulator 10a for immersing and holding the pair of supports 20a and 20a at the bottom to fix the position thereof.

이러한 종래의 음극 구조체는 도시된 바와 같이 히이터(40)를 지지하는 지지체(20a)(20)가 인슐레이터(10a)몸체에 서로 정면으로 마주보도록 되어 있기 때문에 이들의 변형에 의해 히이터도 같이 그 정상위치를 벗어나게 되어있다.In the conventional cathode structure, as shown, the supporters 20a and 20 supporting the heater 40 face each other in front of the body of the insulator 10a. It is supposed to escape.

즉, 상기 지지체(20a)와 히이터(40) 사이에는 지지체의 위치변동에 따른 히이터의 위치이탈을 억제하기 위한 완충수단은 마련되어 있지 않기 때문에 지지체(20a)의 미세한 변형에 의해서도 히이터의 위치변동이 발생된다.That is, since no buffer means is provided between the support body 20a and the heater 40 for suppressing the positional deviation of the heater due to the positional change of the support body, the positional change of the heater occurs even by the minute deformation of the support body 20a. do.

또한 상기한 지지체(20a)의 간격 특히 직각으로 절곡형성된 접속단부(30a)간의 간격이 변동될 수 없도록 고정되어 있어서 미세한 히이터의 저항값 즉 히이터의 양 접속위치의 간격이 변동불능이다. 따라서 한 정류의 음극구조체는 동일기종에만 전용할 수 밖에 없게 된다.In addition, the interval between the support body 20a, in particular, the interval between the connection end portions 30a, which are bent at right angles, is fixed so as not to fluctuate, so that the resistance value of the fine heater, that is, the distance between the two connection positions of the heater, cannot be changed. Therefore, the cathode structure of a rectifier can only be converted to the same model.

본 고안은 지지체의 변형에 따른 히이터의 위치변동이 최대한으로 억제됨과 아울러 위치교정이 용이하며, 아울러 히이터의 전기저항을 용이하게 변경할 수 있는 음극선관용 전자총의 직열형 음극구조체를 제공함에 그 목적이 있다.The object of the present invention is to provide a direct cathode structure of an electron gun for a cathode ray tube which can suppress the positional change of the heater according to the deformation of the support to the maximum and facilitate the position correction, and can easily change the electric resistance of the heater. .

본 고안의 다른 목적은 제조단가가 저렴하며, 제조 가공이 용이한 음극선관용 전자총이 직열형 캐소오드 구조체를 제공함에 있다.Another object of the present invention is to provide a cathode-type cathode structure with an electron gun for a cathode ray tube, which is low in cost and easy to manufacture.

이하 첨부된 도면을 통하여 본 고안을 더욱 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

제 2 도에 본 고안의 한 실시예가 도시되어 있는 바, 종래의 음극구조체와는 달리 히이터(40)의 양단부를 지지하는 지지체(20b)가 인슐레이터(10b)의 몸체에 원형공간부(11b)을 중앙으로 하여 그 양측의 대각선 방향으로 엇갈리게 형성된 관통공(12b)에 고정된채 히이터(40)의 양단이 용접되는 각 상단부의 접속단부(30b)는 서로 반대방향을 바라보도록 되어 있다. 그리고 제 3b 도에 도시되어 있는 바와 같이 양측지지체(20b)가 삽입 파지되는 관통공(12b)의 개구부 둘레에는 상기 지지체(20b)를 둘러 싸도록 된 환형공간부(13b)가 요철형성되어서 이에 지지체(20b)를 고착시키는 접착제(60)가 일정량 고일수 있도록 되어 있다.2 shows an embodiment of the present invention, unlike the conventional cathode structure, a support 20b for supporting both ends of the heater 40 has a circular space portion 11b formed on the body of the insulator 10b. The connecting end portions 30b of the upper end portions of the upper ends of the heaters 40, which are welded to both ends of the heater 40, are fixed to the through holes 12b staggered in the diagonal directions on both sides thereof so as to face opposite directions. As shown in FIG. 3B, an annular space portion 13b formed around the support 20b is formed around the opening of the through hole 12b in which both side supports 20b are inserted and gripped, thereby supporting the support. The adhesive 60 for fixing the 20b can be fixed in a fixed amount.

이와 같이 구성된 음극구조체에 있어서 상기 지지체(20b) 상단의 접속단부(30b)(30b)가 서로 다른 방향을 바라보도록 되어 있어서, 상기 접속단부(30b)을 시계방향 또는 반시계방향으로 각각 비틀므로써 히이터의 용접간격을 용이하게 변형시킬수 있고, 경우에 따라서 히이터의 위치가 이탈되었을 때에도 상기 접속단부(30b)를 변형시킴으로써 용이하게 위치를 바로잡을 수 있다. 여기에서 히이터 용접간격을 변경시킬 수 있다함은 히이터의 저항값을 변경하여 여러종류의 음극선관에의 사용이 가능하다는 것을 말하는 것으로서, 동일한 제원의 음극선관에 사용될 때에도 히이터의 저항값을 변경함으로써 소비전력의 조절이 가능하게 된다.In the negative electrode structure configured as described above, the connection end portions 30b and 30b of the upper end of the support 20b face each other in a different direction, so that the heater is twisted in the clockwise or counterclockwise direction, respectively. It is possible to easily change the welding spacing, and in some cases, even when the position of the heater is displaced, the position can be easily corrected by deforming the connection end portion 30b. Here, the change in the heater welding interval means that the heater can be used for various types of cathode ray tubes by changing the resistance value of the heater, and it is consumed by changing the resistance value of the heater even when used for cathode ray tubes of the same specification. The power can be adjusted.

한편 상기한 인슐레이터에는 상기 지지체를 용착시키는 접착제가 일정량 담길 수 있도록 환형공간부가 형성되어 있어서, 종래와 같이 지지체 주위에 돔형으로 접착제를 고착 성형할 필요가 없고 일정량의 접착제를 상기 환형공간부에 고이게 하여만 두면 된다. 따라서 종래와 같이 지지체 주위에 접착제를 돔형으로 형성시키기 위하여 주의를 기울일 필요가 없게 되고, 흘러내린 접착제에 의해 지지체의 용접부위가 오염되지 않으므로 이에 의한 제품의 불량발생률이 저감된다.On the other hand, the insulator has an annular space portion formed to contain a predetermined amount of the adhesive for welding the support, so that there is no need to fix the adhesive in a dome shape around the support as in the prior art, and a certain amount of adhesive is accumulated in the annular space portion. You just have to leave. Therefore, it is not necessary to pay attention to form the dome around the support as in the prior art, and the welded portion of the support is not contaminated by the spilled adhesive, thereby reducing the defective rate of the product.

이와 같은 본 고안은 인슐레이터의 한정된 공간내에서 히이터의 용접간 거리 즉 저항값을 변경할수 있도록 되어 있어서 여러 규칙의 제품으로의 변경이 용이함은 물론, 지지체가 제조되는 과정에서 발생된 고정위치의 오차를 손쉽게 바로 잡을 수 있고, 접착제가 고인채 고착될 수 있는 환형공간부를 구비하고 있어서 접착제 본딩작업이 매우 간편한 특징을 가진다.This invention is designed to change the distance between the welding of the heater, the resistance value within the limited space of the insulator, so that it is easy to change to the product of various rules, as well as the error of the fixed position generated in the process of manufacturing the support Easily corrected, and has an annular space that can be fixed while the adhesive is stuck, the adhesive bonding operation is very easy.
