본 고안은 음극선관의 각종 전·자기적 특성의 검사 및 교정 작업시 검사대상 음극선관에 해당 검사장치의 전원을 인가함에 있어서, 특히 음극선관의 급전핀들중 그 인가전압값의 빈번한 측정체크가 요구되는 특정 급전핀에 대한 인가전압을 보다 간편용이하게 측정할 수 있도록 하기 위해 안출된 음극선관 검사장치용 소켓에 관한 것이다.The present invention requires the frequent measurement check of the applied voltage value among the feed pins of the cathode ray tube, especially when applying the power of the inspection apparatus to the cathode ray tube to be inspected during the inspection and calibration of various electric and magnetic characteristics of the cathode ray tube. The present invention relates to a socket for a cathode ray tube inspection device, which is designed to more easily measure an applied voltage to a specific feed pin.

일반적으로 완성된 음극선관은 이의 전·자기적 특성을 검사 조정하여 주는 과정을 거치게 되는데 이를 통상적으로 ITC(Intergrated Tube Component)조정작업이라 칭한다. 이러한 ITC조정작업은 이를 위한 적정의 검사장치를 이용하여 수행하게되는데, 그 검사방법은 다음과 같다.In general, the finished cathode ray tube undergoes a process of inspecting and adjusting its electric and magnetic properties, which is commonly referred to as ITC (Intergrated Tube Component) adjustment work. This ITC adjustment is carried out using a suitable inspection apparatus for this purpose. The inspection method is as follows.

즉, 완성된 음극선관의 네트부에 있는 복수개의 급전핀들에 검사장치로부터의 소켓을 결합하여 준 다음, 검사장치를 작동시켜 이의 소켓을 통하여 각 급전핀에 적정의 전압을 인가시켜 줌으로써, 전자총의 각 그리드에 요구되는 바의 전압이 걸리도록 하여 이들 그리드 전극들간에 전자빔의 접속 및 가속에 필요한 전자기적 렌즈들이 형성되도록 해준다.That is, the socket from the inspection apparatus is coupled to the plurality of feeding pins in the net portion of the completed cathode ray tube, and then the inspection apparatus is operated to apply an appropriate voltage to each feeding pin through the socket. The voltage required for each grid is applied to allow the formation of the electromagnetic lenses needed to connect and accelerate the electron beam between these grid electrodes.

상기 과정에서, 음극선관의 각 급전핀들중 통상적으로 3번핀(또는 L3)단자)으로 불리우는 한 급전핀에는 소위 전자총의 포커스전압인 EC3 전압이 인가되게 되는데, 이 급전핀에 걸리는 포커스전압은 관련 전자총의 각 부위에 대한 인가전압중 가장 높은 기준전압이 되기 때문에, 관련 검사작업시 상기 급전핀에 걸리는 포커스전압이 요구되는 전압값 범위로 인가되는지의 여부를 측정체크해 주어야 하게 된다.In the above process, one of the feed pins of the cathode ray tube, commonly referred to as pin 3 (or L3 terminal), is supplied with an EC3 voltage, which is a focus voltage of an electron gun, and the focus voltage applied to the feed pin is related to an electron gun. Since the reference voltage is the highest among the voltages applied to each part of the circuit, it is necessary to check whether or not the focus voltage applied to the feed pin is applied within the required voltage value range during the related inspection operation.

종래에는 상기 급전핀에 걸리는 포커스전압을 체크하기 위하여 해당 음극선관의 네트부 후단에 결합되어 그 네크부 후단상의 각 급전핀에 전원을 인가하는 소켓이 음극선관측의 급전핀들과의 결합단자부가 있는 부위와 상기 부위의 음극선관과의 결합 반대측을 덮어 보호하는 부위로 분리형성되고 목적한 급전핀상의 포커스전압측정시에는 상기 소켓의 두 부위들을 분리한 상태로 전압측정을 한 후 이들 부위를 다시 결합해주어야 했기 때문에 매우 번거롭고 시간이 많이 소요되는 문제점이 있었다.Conventionally, a socket coupled to a net end of a corresponding cathode ray tube to check a focus voltage applied to the feed pin, and to supply power to each feed pin on the rear end of the neck portion, has a coupling terminal portion with a feed pin of a cathode ray tube side. When the focus voltage is measured on the feed pin, the two parts of the socket are separated and the voltage is measured again. Because it had to be very troublesome and time-consuming problems.

따라서, 본 고안의 목적은 상기한 취지의 음극선관 검사시 상술한 포커스전압이 걸리는 급전핀에 대한 인가전압체크를 전원 소켓을 일일히 분해조립하지 않고도 간편용이하게 할 수 있는 더욱 개선된 음극선관 검사장치용 소켓을 제공함에 있다.Accordingly, an object of the present invention is to further improve the cathode ray tube inspection, which can make the applied voltage check for the feed pin to which the above-mentioned focus voltage is applied when the cathode ray tube inspection as described above can be easily performed without disassembling and assembling the power socket. In providing a socket for a device.

상기의 목적을 달성하기 위한 본 고안은 소켓본체의 일측에 상기 포커스전압이 인가되는 급전핀과 대응되는 위치헤 형성한 통공과, 간단히 회동조작으로 상기 통공을 개폐할 수 있는 개폐판을 구비한 것에 특징이 있다.The present invention for achieving the above object is provided with a through hole formed in a position corresponding to the feed pin to which the focus voltage is applied to one side of the socket body, and an opening and closing plate that can open and close the through hole simply by a rotation operation. There is a characteristic.

이하, 본 고안의 바람직한 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 소켓본체(200)가 음극선관(100)의 네크부(110)에 있는 복수개의 급전핀(111)이 결합되는 터미널블럭(210)과, 상기 네크부(110)에 끼워지는 홀더(201)와, 상기 터미널블럭을 지지하는 지지판(202)과, 상기 터미널블럭에 결합되는 각 급전핀과 대응토록 구비되는 복수개의 단자(220)와, 상기 각 단자에 검사장치의 전원을 인가하는 전선(230)을 포함하여 구성되는 음극선관 검사장치용 소켓에 있어서, 상기 소켓본체(200)의 일측에 음극선관(100)측의 급전핀(111)들중 포커스전압이 인가되는 급전핀과 대응 결합되는 단자(220)에 예컨대 전압측정용 탐침과 같은 전압측정수단을 소켓본체(200) 외부로부터 접근시킬 수 있도록 천공형성한 통공(240)과, 간단한 회동조작에 의해 상기 통공(240)을 개폐할 수 있도록 소켓본체(200)에 결합설치된 개폐판(250)을 구비하여서 된 것이다. 상기 개폐판(250)은 그 일측이 통공(240)을 덮어 가릴 수 있는 정도의 폭을 가지는 판상의 몸체로 되고, 이의 한쪽을 힌지핀(251)을 중심으로 회동가능하게 소켓본체(200)를 구속시켜 설치한다.The present invention is a socket body 200 is a terminal block 210 to which a plurality of feed pins 111 in the neck portion 110 of the cathode ray tube 100 is coupled, and a holder fitted to the neck portion 110 ( 201, a support plate 202 for supporting the terminal block, a plurality of terminals 220 provided to correspond to each of the power supply pins coupled to the terminal block, and a wire for applying a power supply to the respective terminals. In the socket for a cathode ray tube inspection apparatus comprising a 230, the one of the socket body 200 of the feed pins 111 of the feed pins 111 of the cathode ray tube 100 side correspondingly coupled with the feed pin is applied A through-hole 240 is formed so as to access the terminal 220, for example, a voltage measuring means such as a voltage measuring probe from the outside of the socket body 200, and to open and close the through-hole 240 by a simple turning operation. It is equipped with an opening and closing plate 250 coupled to the socket body 200 so that A. The opening and closing plate 250 is a plate-shaped body having a width of one side thereof to cover the through hole 240, one side thereof is rotatable around the hinge pin 251 to the socket body 200 Restraint and install.

상기와 같이 구성하여서 되는 본 고안은 완성된 음극선관의 전·자기적 특성의 검사시 소켓본체(200)의 홀더(201)를 음극선관(100)의 네크부(110)에 끼우되 이의 터미널블럭(210)이 음극선관(100)측의 각 급전핀(111)에 결합되도록 한 다음, 검사장치의 전원을 전선(230)을 통하여 각 단자(220)에 인가시키면 이 단자(220)와 서로 대응결합되어 있는 각 급전핀(111)에 소망되는 전압이 인가되는 것이다.The present invention constituted as described above, the holder 201 of the socket body 200 is inserted into the neck portion 110 of the cathode ray tube 100 during the inspection of the electric and magnetic properties of the completed cathode ray tube, but the terminal block thereof After the 210 is coupled to each of the feed pins 111 on the cathode ray tube 100 side, the power of the inspection apparatus is applied to each terminal 220 through the wire 230 to correspond to each other. The desired voltage is applied to each of the feed pins 111 coupled.

이때, 상기 음극선관(100)의 급전핀(111)들중 3번핀에 인가되는 포커스전압을 측정체크하고자 할 때에는, 상술한 바와 같이 소켓본체(200)에 제공되어 있는 통공(240)을 통하여 소켓본체(200)를 분해하지 않고도 목적한 전압측정작업을 간편히 할 수 있는 것이다.At this time, when the focus voltage applied to the third pin of the feed pins 111 of the cathode ray tube 100 is to be measured, the socket through the through hole 240 provided in the socket body 200 as described above. It is possible to simplify the desired voltage measurement work without disassembling the main body 200.

즉, 상기 소켓본체(200)의 통공(240)은 상기 3번핀과 대응결합되는 단자(220)의 위치에 형성제공되어 있으므로 평상시에는 개폐판(250)을 제1도의 이점쇄선으로 도시된 바와 같은 위치로 하여 통공(240)을 덮어두었다가(먼지와 같은 이물이 소켓본체(200)내부로 침투하지 못하도록)측정시에 이를 제1도의 실선도시위치로 회동시켜 통공(240)이 열리게한 후 전압측정기의 검사봉(300)을 제2도의 예와 같이 상기 통공(240)을 통하여 단자(220)에 접근 연결시켜 준다.That is, since the through hole 240 of the socket body 200 is provided at the position of the terminal 220 corresponding to the third pin, the opening and closing plate 250 is normally shown as an advantage chain line of FIG. After covering the through hole 240 in a position (so that foreign matter such as dust does not penetrate into the inside of the socket main body 200), it is rotated to the solid line illustrated in FIG. 1 to open the through hole 240 to open the voltage meter. The test rod 300 is connected to the terminal 220 through the through hole 240 as in the example of FIG.

이렇게 하면 상기 단자에 인가되는 전압값이 측정되므로, 결과적으로 상기 단자와 연결된 급전핀인 3번핀에 걸리는 포커스전압이 측정되는 것이다.In this case, since the voltage value applied to the terminal is measured, the focus voltage applied to pin 3, which is a feed pin connected to the terminal, is measured.

측정이 끝나면 상기 개폐판(250)을 다시 제1도의 이점쇄선 도시위치로 회동시켜 통공(240)을 닫아주도록 한다.After the measurement, the opening and closing plate 250 is rotated again to the position shown in Fig. 1 of the dashed chain to close the through hole 240.

이상에서와 같은 본 고안의 소켓은 상술한 구성, 작용에 의한 음극선관의 전자기적 특성검사시 그 급전핀들 중 한 급전핀에 걸리는 포커스전압이 측정을 소켓본체를 분해하지 않고도 간편신속하게 행할 수 있게 된 신규유용한 고안인 것이다.In the socket of the present invention as described above, the focus voltage applied to one of the feed pins during the electromagnetic characteristic inspection of the cathode ray tube by the above-described configuration and action enables the measurement to be performed quickly and easily without disassembling the socket body. It is a new useful design.
