Description
본 발명은, 액정표시패널의 백라이트용 광원 등으로서 사용되는 냉 음극관을 위한 접속구조 및 이것을 이용하는 단자부재, 및 이 단자부재의 연쇄체에 관한 것이다.The present invention relates to a connection structure for a cold cathode tube used as a light source for a backlight of a liquid crystal display panel, a terminal member using the same, and a chain member of the terminal member.
액정표시패널의 백라이트 유닛은, 예컨대, 백라이트용 광원으로서의 냉 음극관(형광램프)과, 이 냉 음극관으로부터의 가시광을 액정표시패널의 각 부에 도입하는 도광판과, 이 도광판과 액정표시패널과의 사이에 끼워장착되어서 빛을 확산시키는 광확산판(광확산 시트)과, 도광판의 배후에 배치되어서 액정표시패널측에 빛을 반사하는 반사판(반사 시트)을 구비하고 있다.The backlight unit of the liquid crystal display panel includes, for example, a cold cathode tube (fluorescent lamp) as a light source for a backlight, a light guide plate for introducing visible light from the cold cathode tube to each part of the liquid crystal display panel, and the light guide plate between the liquid crystal display panel. And a reflecting plate (reflective sheet) disposed behind the light guide plate and reflecting light on the liquid crystal display panel side.
냉 음극관은, 예컨대, 도광판의 끝면을 따르도록 곧은 관형상으로 형성되고, 이 양끝에 리드단자를 보유하고 있다. 이 양끝의 리드단자에, 피복전선으로 이루어지는 급전선이 접속된다. 이 급전선을 통해서, 고주파 전력 급전장치로부터, 예컨대, 주파수 50Hz, 전압 1200V(rms)의 고주파 전압이, 냉 음극관의 양끝의 리드단자에 인가된다. 이것에 의해, 냉 음극관 내부에서 방전이 발생하고, 이 방전을 수반하여 발생한 적외선이 냉 음극관의 내벽에 형성된 형광체층을 여기함으로써, 가시광이 발생한다.The cold cathode tube is, for example, formed in a straight tubular shape along the end face of the light guide plate, and has lead terminals at both ends thereof. A feeder wire made of a coated wire is connected to the lead terminals at both ends. Through this feed line, a high frequency voltage of, for example, a frequency of 50 Hz and a voltage of 1200 V (rms) is applied to the lead terminals of both ends of the cold cathode tube. Thereby, discharge generate | occur | produces inside a cold cathode tube, and visible light generate | occur | produces when the infrared rays which generate | occur | produced with this discharge excite the fluorescent substance layer formed in the inner wall of a cold cathode tube.
리드단자와 급전선의 접속은, 땜납 접합에 의해서 달성되는 것이 일반적이다. 즉, 급전선을 구성하는 피복전선의 끝부의 피복을 미세 길이정도 박리하고, 이것에 의해, 내부의도선을 노출시킨다. 이 도선과 리드단자가 땜납에 의해 접합된다. 도선이 꼬인 선으로 이루어져 있는 경우에는, 이것을 미리 땜납통 안에 경사지게 하여 꼬인 선을 통합하고, 그 상태로 도선과 리드단자의 땜납 접합을 행하는 것이므로 작업효율이 향상한다.Connection of the lead terminal and the feeder is generally achieved by solder bonding. That is, the coating | cover of the edge part of the covering wire which comprises a feeder line is peeled about fine length, and this exposes an internal conductor wire. This lead wire and lead terminal are joined by soldering. In the case where the conductor is made of twisted lines, it is inclined in the solder container beforehand to integrate the twisted lines, and solder joining of the conductor and the lead terminal is performed in this state, thereby improving work efficiency.
액정표시패널을 이용한 제품에는, 노트북형 퍼스널 컴퓨터나 휴대용 정보단말(소위 PDA(Personal Digital Assistant)) 등이 있다. 이들 제품의 소형화 및 박형화는, 시장에서의 강한 요구이다. 이에 수반하여, 액정표시패널의 백라이트 유닛에 대해서도 소형화가 요구되어 있다. 보다 구체적으로는, 냉 음극관의 세선화가 권장되고 있으며, 관외경 2mm 정도의 냉음극관이 사용되기에 이르렀다.Products using a liquid crystal display panel include a notebook personal computer, a portable information terminal (so-called PDA (Personal Digital Assistant)), and the like. Miniaturization and thinning of these products are strong demands in the market. In connection with this, miniaturization is also required of the backlight unit of a liquid crystal display panel. More specifically, the thinning of the cold cathode tube is recommended, and a cold cathode tube with an outer diameter of about 2 mm has been used.
이와 같은 세선화된 냉 음극관에 대해서 상기 종래의 접속구조를 적용하기에는, 조립작업성, 특히, 냉 음극관에 대한 급전선의 접속작업의 작업성이 아주 나쁘다.In order to apply the conventional connection structure to such thin cold cathode tube, the assembly workability, in particular, the workability of connecting the feed line to the cold cathode tube is very poor.
이 문제는, 예컨대, 냉 음극관의 끝부에 구금을 설치하고, 이 구금을 클립형상의 소켓에 끼워붙이는 구조(예컨대, 일본 특개평5-28803호 공보 참조)를 채용함으로써 개선할 수 있다. 그러나, 이 구조는, 소켓을 배치하는 공간을 필요로 하기때문에, 소형화의 요구에 역행한다. 또한, 구금를 소켓에 끼워붙이는 접속구조에서는, 1000V 이상의 고전압의 인가 시에 있어서의 확실한 도통성을 확보하지 못할 우려가 있고, 안정한 접속구조가 아니다.This problem can be solved by, for example, providing a structure at the end of the cold cathode tube and adopting a structure in which the structure is fitted to the clip-shaped socket (see, for example, Japanese Patent Laid-Open No. 5-28803). However, this structure requires space for arranging sockets, and thus counters the demand for miniaturization. In addition, in the connection structure in which the cap is fitted in the socket, there is a fear that reliable conductance at the time of applying a high voltage of 1000 V or higher may not be secured, and it is not a stable connection structure.

본 발명의 목적은, 접속부에 큰 공간을 필요로 함이 없이 조립작업성을 향상할 수 있는 냉 음극관의 접속구조를 제공하는 것이다.An object of the present invention is to provide a connection structure of a cold cathode tube capable of improving assembly workability without requiring a large space in the connection portion.
또한, 본 발명의 다른 목적은, 이와 같은 냉 음극관의 접속구조에 적용된 단자부재를 제공하는 것이다.Another object of the present invention is to provide a terminal member applied to the connection structure of such a cold cathode tube.
본 발명에 또 다른 목적은, 상기 단자부재의 연쇄체를 제공하는 것이다.Another object of the present invention is to provide a chain member of the terminal member.
본 발명의 냉 음극관의 접속구조는, 리드단자(12, 13)를 보유하는 냉 음극관 (10)과, 관통구멍(53)을 보유하고, 이 관통구멍에 상기 리드단자가 관통된 상태로 상기 냉 음극관에 땜납 접합된 단자부재(5, 6, T, 5A)와, 이 단자부재가 압착된 급전선(21, 22)를 보유한다. 또한, 괄호 안의 영자, 숫자는, 후술하는 실시형태에서의 대응구성요소 등을 표시한다. 단, 본 발명이 해당 실시형태에 한정되는 것을 의도하는 것은 아니다. 이하, 이 사항에는 동일하다.The cold cathode tube connecting structure of the present invention includes a cold cathode tube 10 having lead terminals 12 and 13, and a through hole 53, and the cold terminal tube having the lead terminal penetrated therethrough. The terminal members 5, 6, T, 5A soldered to the cathode tube, and the feed lines 21, 22 on which the terminal members are crimped are held. In addition, alphabetic characters and numerals in parentheses indicate corresponding elements in the embodiments to be described later. However, this invention is not intended to be limited to the said embodiment. Hereinafter, this matter is the same.
이 구성에 의하면, 급전선에 압착된 단자부재의 관통구멍에 냉 음극관의 리드단자를 관통한 후에, 이 리드잔자와 단자부재를 땜납 접합함으로써, 냉 음극관에 급전선을 접속한 어셈블리를 조립할 수 있다. 따라서, 급전선과 냉 음극관의 리드단자를 단지 땜납 접합한 종래기술에 비교하여, 조립작업성을 현격하게 향상할 수 있다. 또한, 냉 음극관에 구금을 고정하고, 이 구금을 클립형상의 소켓에 끼워붙이는 구성에 비교하면, 냉 음극관의 리드단자 부근에 확보해야하는 공간이 현격하게 작아진다. 따라서, 소형화에 대한 요구에도 대응할 수 있다.According to this configuration, after the lead terminal of the cold cathode tube passes through the through-hole of the terminal member crimped to the feed line, the lead residue and the terminal member are solder-bonded to assemble an assembly in which the feed line is connected to the cold cathode tube. Therefore, the assembly workability can be remarkably improved as compared with the prior art in which the lead terminals of the feed line and the cold cathode tube are solder-bonded. In addition, the space to be secured in the vicinity of the lead terminal of the cold cathode tube is significantly smaller than that in the structure in which the detention is fixed to the cold cathode tube and the detention is fitted into the clip-shaped socket. Therefore, the demand for miniaturization can also be met.
상기 급전선은, 도체부(21w)와 이 도체부를 피복하는 피복부(21i)를 보유하는 피복전선이어도 좋다. 이 경우, 피복전선의 상기 도체부에 상기 단자부재가 압착되어 있어도 좋다.The feed wire may be a coated wire having a conductor portion 21w and a covering portion 21i covering the conductor portion. In this case, the terminal member may be crimped to the conductor portion of the coated wire.
이 구성에서는, 피복전선의 도체부에 단자부재가 압착되어 있음으로써, 급전선과 단자부재의 전기접속을 확실하게 행할 수 있다.In this structure, the terminal member is crimped | bonded by the conductor part of a covered wire, and electrical connection of a feeder wire and a terminal member can be reliably performed.
특히, 냉 음극관의 리드단자와 단자부재를 접합하는 땜납(28)을 단자부재와 급전선의 접속부(도체부)까지 미치게 함으로써, 단자부재와 급전선의 사이의 전기접속을 보다 확실하게 행할 수 있다.In particular, by extending the solder 28 for joining the lead terminal of the cold cathode tube and the terminal member to the connecting portion (conductor portion) of the terminal member and the feeder line, the electrical connection between the terminal member and the feeder line can be more reliably performed.
상기 단자부재는, 상기 도체부에 압착되는 도체압착부(51)를 보유하고, 상기 피복부에 압착되는 피복압착부를 보유하고 있지 않은 것이어도 좋다.The terminal member may have a conductor crimping portion 51 pressed against the conductor portion, and may not have a cover crimping portion pressed against the covering portion.
본 발명에서는, 단자부재에는 도체용 몸통만이 구비되어 있어서, 피복전선의 피복부에 압착되는 피복용 몸통이 설치되어 있지 않다. 이것에 의해서, 단자부재 자신을 아주 소형으로 구성할 수 있으므로, 냉 음극관의 리드단바 부근에 설치해야할 접속공간을 보다 작게 할 수 있다.In the present invention, only the conductor body is provided in the terminal member, and the covering body pressed against the covering portion of the covering wire is not provided. As a result, the terminal member itself can be configured to be very compact, so that the connection space to be provided near the lead end bar of the cold cathode tube can be made smaller.
상기 냉 음극관은, 표시패널의 백라이트용 광원으로서 이용되는 것이어도 좋다.The cold cathode tube may be used as a light source for backlight of a display panel.
본 발명의 냉 음극관의 접속구조에서는, 냉 음극관의 리드단자 부근에 큰 공간을 필요로 하지 않기 때문에, 표시패널의 백라이트 유닛을 소형으로 구성하는 것이 가능하고, 또한 표시패널이 짜넣어진 표시장치의 소형화에 기여할 수 있다.In the connection structure of the cold cathode tube of the present invention, since a large space is not required near the lead terminal of the cold cathode tube, it is possible to configure the backlight unit of the display panel in a small size, and to provide a display device in which the display panel is incorporated. It can contribute to miniaturization.
상기 냉 음극관의 접속구조에 적용되는 단자부재의 발명은, 냉 음극관의 리드단자와, 냉 음극관으로의 급전을 위한 급전선을 전기접속하기 위한 단자부재이며, 냉 음극관의 리드단자가 관통되는 관통구멍(53)이 형성된 냉 음극관 접속부 (52)와, 급전선의 도체부에 압착되는 도체압착부(51)를 포함한다.The invention of the terminal member applied to the connection structure of the cold cathode tube is a terminal member for electrically connecting a lead terminal of the cold cathode tube and a feed line for feeding power to the cold cathode tube, and a through hole through which the lead terminal of the cold cathode tube passes ( 53 includes a cold cathode tube connecting portion 52 formed therein, and a conductor crimping portion 51 pressed against the conductor portion of the feed line.
이 단자부재는, 급전선이 피복전선으로 이루어지는 경우에, 그 도체부에 압착되는 도체압착부만을 보유하고, 피복부에 압착되는 피복압착부를 보유하고 있지 않는 것이 바람직하다. 이것에 의해서, 단자부재를 아주 소형으로 형성할 수 있다.When the feed line is made of a coated wire, the terminal member preferably has only a conductor crimp portion that is crimped to the conductor portion, and does not have a cover crimp portion that is crimped on the cover portion. Thereby, the terminal member can be formed very compact.
본 발명의 단자부재 연쇄체는, 띠형상 연결부재(40)에 대해서, 그 띠형상 연쇄부재의 길이방향에 교차하는 방향을 따르는 자세로 상기 복수의 단자부재(T)가 각각 결합되어서 형성된 것이다.The terminal member chain body of the present invention is formed by coupling the plurality of terminal members T with respect to the belt-shaped connecting member 40 in a posture along a direction crossing the longitudinal direction of the belt-shaped chain member.
이 구성에 의하면, 복수의 단자부재는 각 한끝이 띠형상 연결부재에 연결되어 있다. 각각의 단자부재는, 단자부재의 도체압착부가 급전선의 도체부에 압착되기 전 또는 압착된 후에 띠형상 연결부재로부터 분리된다. 이 때, 각 단자부재에 관해서 1개소의 절단에 의해 해당 단자부재는 띠형상 연결부재로부터 분리되게 된다.According to this configuration, each of the plurality of terminal members is connected at one end to the strip-shaped connecting member. Each terminal member is separated from the strip-shaped connecting member before or after the conductor pressing portion of the terminal member is pressed against the conductor portion of the feed line. At this time, the terminal member is separated from the belt-shaped connecting member by one cutting of each terminal member.
종래로부터 이용되고 있는 일반적인 단자부재 연쇄체에서는, 단자부재가 길이방향 양끝이 다른 단자부재에 연결되어 있다. 즉, 복수의 단자부재가 직렬로 연결되어서 다른 단자부재 연쇄체를 형성하고 있다. 이와 같은 구성의 경우, 각각의 단자부재를 단자부재 연쇄체로부터 분리되기 위해서는, 2개소의 절단부위가 필요로된다. 이 2개소에서의 절단처리가 행해짐으로써, 절단 후의 각각의 단자부재의 길이의 제어가 곤란하게 되는 경우가 있다.In a conventional terminal member chain, which is conventionally used, both terminal members are connected to different terminal members in both longitudinal directions. That is, a plurality of terminal members are connected in series to form another terminal member chain. In such a configuration, in order to separate each terminal member from the terminal member chain, two cut portions are required. By performing the cutting process at these two places, it may become difficult to control the length of each terminal member after cutting.

도 1은, 본 발명의 일실시형태에 관한 냉 음극관의 접속구조를 나타내는 사시도이다. 냉 음극관(10)은, 가느다랗고 긴 곧은 관형 밸브(11)와, 이 밸브(11)의 양끝으로부터 인출된 세선형상의 리드단자(12, 13)를 구비하고 있다. 냉 음극관 (10)은, 예컨대, 액정표시패널의 백라이트 유닛에 짜넣어지는 백라이트용 광원으로서 이용된다.1 is a perspective view showing a connection structure of a cold cathode tube according to one embodiment of the present invention. The cold cathode tube 10 is provided with a thin long straight tubular valve 11 and fine wire lead terminals 12 and 13 withdrawn from both ends of the valve 11. The cold cathode tube 10 is used, for example, as a light source for backlight incorporated in a backlight unit of a liquid crystal display panel.
밸브(11)는, 예컨대 관외경이 1.7 ~ 2.0mm, 전장 250 ~ 300mm 정도의 가느다랗고 긴 납유리제 튜브로 이루어져 있다. 밸브(11)의 내부에는, 가령, 전리매체로서, 소정량의 수은과, 소정압의 아르곤(Ar) 및 네온(Ne)으로 이루어지는 혼합된 희석 가스가 밀봉되어 있다. 또한, 밸브(11)의 관내벽에는, 적외선의 조사에 의해 여기되어서 가시광을 발광하는 형광체층이 형성되어 있다. 밸브(11)의 내부의 양끝 부근에는, 리드단자(12, 13)에 각각 접속된 1쌍의 내부전극이 설치되어 있다. 이들 내부 전극 간에서의 방전에 의해 적외선을 발생시키면, 이 적외선에 의해 밸브(11)의 관내벽의 발광체층이 여기되어서, 가시광이 발생하는 구성으로 되어 있다.The valve 11 is made of, for example, a thin long lead glass tube having a tube outer diameter of 1.7 to 2.0 mm and a total length of 250 to 300 mm. In the valve 11, for example, a mixed dilution gas composed of a predetermined amount of mercury and a predetermined pressure of argon (Ar) and neon (Ne) is sealed as an ionizing medium. Moreover, the phosphor layer which is excited by irradiation of infrared rays and emits visible light is formed in the inner wall of the valve 11. Near both ends of the inside of the valve 11, a pair of internal electrodes connected to the lead terminals 12 and 13 are provided, respectively. When infrared rays are generated by the discharge between these internal electrodes, the light emitting layer on the inner wall of the valve 11 is excited by the infrared rays, so that visible light is generated.
리드단자(12, 13)에 고주파 전력공급장치(30)로부터의 고주파 전력을 급전하기 위해서, 피복전선으로 이루어지는 급전선(21, 22)의 각 한끝이 리드단자(12, 13)에 각각 접속되어 있다. 급전선(21, 22)의 각 다른끝은 커넥터(31)에 접속되어 있어서, 이 커넥터(31)가 고주파 전력공급장치(30)에 장착되도록 되어 있다.In order to feed the high frequency power from the high frequency power supply device 30 to the lead terminals 12 and 13, one end of each of the feed lines 21 and 22 made of the coated wire is connected to the lead terminals 12 and 13, respectively. . The other ends of the feed lines 21 and 22 are connected to the connector 31 so that the connector 31 is attached to the high frequency power supply device 30.
급전선(21, 22)의 리드단자(12, 13)측의 끝부에는, 단자부재(5, 6)가 각각 압착되어 있다. 이 단자부재(5, 6)와 리드단자(12, 13)와 각각 땜납 접합됨으로써, 리드단자(12, 13)와 급전선(21, 22)의 사이의 전기적 접속이 달성되어 있다. 이 실시형태에서는, 급전선(21, 22)은, 리드단자(12, 13)로부터, 냉 음극관(10)의 길이방향과 교차하는 방향으로 인출되어 있다.Terminal members 5 and 6 are crimped to the ends of the lead terminals 12 and 13 of the feeder lines 21 and 22, respectively. By soldering the terminal members 5, 6 and the lead terminals 12, 13, respectively, electrical connection between the lead terminals 12, 13 and the feed lines 21, 22 is achieved. In this embodiment, the feed lines 21 and 22 are drawn out from the lead terminals 12 and 13 in the direction crossing the longitudinal direction of the cold cathode tube 10.
냉 음극관(10)의 양끝 부근에는 수지제의 절연캡(23, 24)이 끼워 넣어지고, 리드단자(12, 13)와 급전선(21, 22)의 접속부의 보호가 도모되도록 되어 있다.Insulating caps 23 and 24 made of resin are sandwiched between both ends of the cold cathode tube 10 to protect the connection portions of the lead terminals 12 and 13 and the feed lines 21 and 22.
도 2는, 급전선(21) 및 단자부재(5)의 구성을 설명하기 위한 사시도이다. 급전선(21)은, 피복전선으로 이루어져 있어서, 도전선 금속(예컨대 동)으로 이루어지는 와이어 형상의 도체부(21w)(가령, 꼬인 선형상의 것)와, 이 도체부(w)를 피복하는 피복부(21i)로 구성되어 있다. 피복부(21i)는, 절연재료(전형적으로는 수지재료)로 이루어진다.2 is a perspective view for explaining the configuration of the feeder line 21 and the terminal member 5. The feed line 21 is made of a coated wire, and includes a wire-shaped conductor portion 21w (for example, twisted linear one) made of a conductive wire metal (for example, copper), and a coating portion covering the conductor portion w. It consists of 21i. The coating portion 21i is made of an insulating material (typically a resin material).
급전선(21)은, 그 한끝에 있어서 피복부(21i)가 미세 길이정도 노출되어 있다. 이 노출된 도체부(21w)에 단자부재(5)가 단자 자동압착장치(도시않함)를 이용하여 압착된다.At one end of the feed line 21, the covering portion 21i is exposed to a fine length. The terminal member 5 is crimped | bonded to this exposed conductor part 21w using a terminal automatic crimping device (not shown).
단자부재(5)는, 도체부(21w)에 압착되는 도체용 몸통(51)와, 이 도체용 몸통(51)에 연결되어 접촉된 냉 음극관 접속부(52)를 보유하고 있다. 도체용 몸통 (51)는, 와이어 형상의 도체부(21w)를 따르는 단면 U자형상을 보유하고 있다. 이 도체용 몸통(51) 내에 도체부(21w)를 배치한 상태로, 단자 자동압착장치에 의해 도체용 몸통(51)를 코킹함으로써, 도 2(b)에 나타내는 바와 같이 단자부재(5)를 급전선(21)의 도체부(21w)에 압착할 수 있다.The terminal member 5 has a conductor body 51 pressed against the conductor portion 21w and a cold cathode tube connection portion 52 connected to and in contact with the conductor body 51. The conductor body 51 has a cross-sectional U-shape along the wire-shaped conductor portion 21w. By caulking the conductor body 51 by the terminal automatic crimping device in a state where the conductor portion 21w is disposed in the conductor body 51, the terminal member 5 is shown in Fig. 2B. The conductor portion 21w of the feeder line 21 can be crimped.
냉 음극관 접속부(52)는, 도체부(21w)의 길이방향을 따르는 거의 원판형상으로 형성되어 있어서, 그 거의 중앙에는 관통구멍(관통구멍)(53)이 형성되어 있다. 거의 원판형상의 냉 음극관 접속부(52)는, 그 직경이, 냉 음극관(10)의 밸브(11)의 관외경에 거의 같지만 이보다 약간 작게 이루어지도록 그 크기가 정해져 있다. 또한, 도체용 몸통(51)의 도체부(21w)를 따르는 길이는, 단자부재(5)의 급전선(21)에 대한 압착이 확실하게 행해지는 필요최소한의 길이로 정해져 있다.. 이 실시형태에서는, 도체용 몸통(51) 및 냉 음극관 접속부(52)를 포함하는 단자부재(5)의 전장(도체부(21w)의 길이방향을 따르는 전장)이, 약 2.5mm 또는 그 이하로 되도록 도체용 몸통(51) 및 냉 음극관 접속부(52)의 크기가 정해져 있다.The cold cathode tube connection part 52 is formed in substantially disk shape along the longitudinal direction of the conductor part 21w, and the through hole (through hole) 53 is formed in the substantially center. The substantially disk-shaped cold cathode tube connecting portion 52 is sized so that its diameter is made substantially the same as the tube outer diameter of the valve 11 of the cold cathode tube 10 but slightly smaller than this. In addition, the length along the conductor portion 21w of the conductor body 51 is determined to be the minimum length necessary for reliably crimping the power supply line 21 of the terminal member 5. In this embodiment, , The conductor body such that the overall length of the terminal member 5 including the conductor body 51 and the cold cathode tube connecting portion 52 (the overall length along the longitudinal direction of the conductor portion 21w) is about 2.5 mm or less. The size of 51 and the cold cathode tube connection part 52 is determined.
피복전선에 압착되는 통상의 단자부재에는, 피복전선의 도체부에 압착되는 도체밸브와, 피복부에 압착되는 피복몸통(피복압착부)가 구비되어 있지만, 이 실시형태에 관한 단자부재(5)에는, 소형화를 위해서, 피복몸통은 구비되어 있지 않다.The normal terminal member to be crimped to the coated wire is provided with a conductor valve which is pressed to the conductor portion of the coated wire and a sheathing body (coated crimp) to be crimped to the sheathed portion, but the terminal member 5 according to this embodiment. For the sake of miniaturization, the covering body is not provided.
도 3은, 단자부재(5)가 압착된 급전선(21)을 냉 음극관(10)의 리드단자(12)에 접속하여 냉 음극관 어셈블리를 조립하는 조립작업을 설명하기 위한 사시도이다. 이 조립작업은, 자동화가 곤란하고, 통상은, 수작업에 의해서 행해진다.3 is a perspective view for explaining the assembling operation of assembling the cold cathode tube assembly by connecting the feed line 21 on which the terminal member 5 is compressed to the lead terminal 12 of the cold cathode tube 10. This assembling work is difficult to automate, and is usually performed by manual labor.
우선, 도 3(a)(b)에 나타내는 바와 같이, 급전선(21)에 압착된 상태의 단자부재(5)의 관통구멍(53)에 냉 음극관(10)의 리드단자(12)가 관통시켜진다. 이 상태에서, 도 3(c)에 나타내는 바와 같이, 땜납(28)(도 3(c)에서는 단면을 나타낸다.)에 의해서 단자부재(5)와 리드단자(12)가 접합된다. 이 때, 단자부재(5)는 그 전장이 아주 짧게 형성되어 있으므로, 땜납(28)의 일부는, 도체용 밸브(51) 및 이 도체용 몸통(51)에 압착되어 있는 도체부(21w)에도 미친다. 따라서, 땜납(28)은, 리드단자(12)와 단자부재(5)를 전기적 및 기계적으로 접속함과 아울러, 단자부재(5)와 급전선(21)의 도체부(21w)의 전기적 접속의 확보에도 기여할 수 있다.First, as shown in Fig. 3 (a) (b), the lead terminal 12 of the cold cathode tube 10 passes through the through hole 53 of the terminal member 5 in a state of being pressed against the feed line 21. Lose. In this state, as shown in Fig. 3C, the terminal member 5 and the lead terminal 12 are joined by the solder 28 (the cross section is shown in Fig. 3C). At this time, the terminal member 5 is formed with a very short length, so that a part of the solder 28 is also pressed against the conductor valve 51 and the conductor portion 21w that is pressed against the conductor body 51. Crazy Therefore, the solder 28 connects the lead terminal 12 and the terminal member 5 electrically and mechanically, and ensures the electrical connection between the terminal member 5 and the conductor portion 21w of the feed line 21. Can also contribute.
급전선(22)과 리드단자(13)의 접속구조는, 급전선(21)과 리드단자(12)와의 접속구조와 마찬가지이다. 즉, 단자부재(6)는, 단자부재(5)와 마찬가지의 구성을 보유하고 있다. 또한, 이 단자부재(6)의 냉 음극관 접속부에 형성된 관통구멍에 리드단자(13)가 관통되어서, 단자부재(6)와 리드단자(13)가 땜납 접합됨으로써, 리드단자(13)와 급전선(22)의 전기적 및 기계적 접합이 달성된다. 단자부재(5, 6)를 리드단자(12, 13)에 접합한 후에는, 리드단자(12, 13)의 불필요 부분(밸브(11)와는반대측의 부분)이, 필요에 따라서 절단된다.The connection structure of the feed line 22 and the lead terminal 13 is the same as that of the feed line 21 and the lead terminal 12. That is, the terminal member 6 has the same structure as the terminal member 5. Further, the lead terminal 13 penetrates through the through hole formed in the cold cathode tube connecting portion of the terminal member 6, and the terminal member 6 and the lead terminal 13 are solder-bonded, whereby the lead terminal 13 and the feed line ( 22) electrical and mechanical bonding is achieved. After the terminal members 5 and 6 are joined to the lead terminals 12 and 13, unnecessary portions of the lead terminals 12 and 13 (parts opposite to the valve 11) are cut as necessary.
이상과 같이, 본 실시형태의 냉 음극관의 접속구조에 의하면, 급전선(21, 22)에 압착된 상태의 단자부재(5, 6)의 관통구멍(53)에 리드단자(12, 13)를 관통함으로써, 이 리드단자(12, 13) 상에 단자부재(5, 6)를 임시 지지할 수 있다. 이와 같이 임시 지지된 단자부재(5, 6)의 리드단자(12, 13)에 대한 땜납 접합은, 양호한 작업성으로 행할 수 있다. 그 결과, 냉 음극관(10)에 급전선(21, 22)이 접속된 냉 음극관 어셈블리를 양호한 작업효율로 조립할 수 있다.As described above, according to the connection structure of the cold cathode tube of the present embodiment, the lead terminals 12 and 13 penetrate the through-holes 53 of the terminal members 5 and 6 in the state of being pressed against the feed lines 21 and 22. By doing so, the terminal members 5 and 6 can be temporarily supported on the lead terminals 12 and 13. The solder joint to the lead terminals 12 and 13 of the terminal members 5 and 6 temporarily supported in this way can be performed with good workability. As a result, the cold cathode tube assembly in which the feed lines 21 and 22 are connected to the cold cathode tube 10 can be assembled with good working efficiency.
또한, 냉 음극관의 끝부에 구금을 설치하고, 이 구금을 클립형상의 소켓에 끼워부착시키는 구성의 경우와 비교하면, 냉 음극관(10)의 끝부에 있어서 급전선 (21, 22)의 접속을 위하여 확보해야할 공간이 현격하게 작아진다. 또한, 리드단자 (12, 13) 및 단자부재(5, 6)의 사이, 및 단자부재(5, 6) 및 급전선(21, 22)의 도체부 (21w)의 사이가 각각 땜납(28)에 의해서 전기접속되고나서, 리드단자(12, 13)와 급전선(21, 22)의 사이의 도통을 확보할 수 있다. 이것에 의해서, 고주파 전력공급장치(30)로부터 발생되는 고주파 전력(예컨대 주파수 51kHz, 전압 1200V(rms))을 냉 음극관(10)의 내부 전극에 확실하게 인가할 수 있다.In addition, as compared with the case where a detention is provided at the end of the cold cathode tube and the detention is fitted into a clip-shaped socket, it is secured for the connection of the feed lines 21 and 22 at the end of the cold cathode tube 10. The space to do is significantly smaller. In addition, between the lead terminals 12 and 13 and the terminal members 5 and 6, and between the terminal members 5 and 6 and the conductor portions 21w of the feed lines 21 and 22, respectively, are applied to the solder 28. By the electrical connection, the conduction between the lead terminals 12, 13 and the feed lines 21, 22 can be ensured. As a result, high frequency power (for example, frequency 51 kHz, voltage 1200 V (rms)) generated from the high frequency power supply device 30 can be reliably applied to the internal electrode of the cold cathode tube 10.
도 4는, 단자 자동압착장치에 의해서 급전선(21, 22)에 압착되기 전의 단자부재(5, 6)의 공급형태인 단자부재 연쇄체의 구성을 나타내는 사시도이다. 이 단자부재 연쇄체는, 상기 단자부재(5, 6)로서 이용될 단자부재(T)(단자부재(5, 6)와 동일 구성을 보유하고 있다.)가, 띠형상 연결부재(40)의 일방측에 거의 일정한 간격으로 결합되어서 구성되어 있다.4 is a perspective view showing the structure of a terminal member chain which is a supply form of the terminal members 5 and 6 before being crimped to the feed lines 21 and 22 by the terminal automatic crimping device. The terminal member chain member has a terminal member T (having the same configuration as that of the terminal members 5 and 6) to be used as the terminal members 5 and 6 of the belt-shaped connecting member 40. It is composed of one side coupled to almost constant interval.
각각의 단자부재(T)는, 냉 음극관 접속부(52)와 띠형상 연결부재(60)의 일방측에 돌출설치된 돌기부(41)가 연결접촉함으로써, 띠형상 연결부재(40)에 결합되어 있다. 돌기부(41)는, 도체용 몸통(51)에 대향하는 위치에 있어서 냉 음극관 접속부 (52)에 연결접촉되어 있다. 이것에 의해, 각각의 단자부재(T)는, 띠형상 연결부재 (40)의 길이방향에 직교하는 자세로 지지되어 있다.Each terminal member T is coupled to the belt-shaped connecting member 40 by the cold cathode tube connecting portion 52 and the protrusion 41 protruding from one side of the belt-shaped connecting member 60. The projection part 41 is in contact with the cold cathode tube connecting portion 52 at a position facing the conductor body 51. As a result, each terminal member T is supported in a posture perpendicular to the longitudinal direction of the belt-shaped connecting member 40.
띠형상 연결부재(40)에는, 단자부재(T)의 간격과 동일한 간격으로 공작물 이송구멍(42)이 그 길이방향을 따라 배열되어서 형성되어 있다. 공작물 이송구멍 (42)은, 단자 자동압착장치에 있어서, 이 단자부재 연쇄체를 공작물 이송고리에 의해서 자동적으로 반송하면서, 복수개의 급전선에 대해서 각각 단자부재(T)를 순차 압착하여 갈 목적으로 사용된다.The strip | belt-shaped connection member 40 is formed by arrange | positioning the workpiece feed hole 42 along the longitudinal direction at the same interval as the space | interval of the terminal member T. As shown in FIG. In the terminal automatic crimping device, the workpiece conveying hole 42 is used for the purpose of sequentially pressing the terminal member T with respect to a plurality of feed lines while automatically conveying the terminal member chain by the workpiece conveying ring. do.
단자 자동압착장치에서는, 예컨대, 공작물 이송구멍(42)을 이용하여 압착처리대상의 단자부재(T)를 위치결정한 상태로, 단자부재(T)의 도체용 몸통(51)에 급전선의 도체부가 배치된다. 이 상태로, 적당한 다이를 이용하여 도체용 몸통(51)을 상하로부터 코킹함으로써, 도체용 몸통(51)가 급전선의 도체부에 압착된다. 이 압착처리 후에, 단자 자동압착장치에 구비된 절단기구에 의해, 돌기부(41)와 냉 음극관 접속부(53)의 사이가 절단된다. 이렇게 하여, 단자부재(T)가 압착된 상태의 급전선이 얻어진다.In the terminal automatic crimping device, for example, the conductor portion of the feed line is disposed on the conductor body 51 of the terminal member T in a state where the terminal member T to be crimped is positioned using the workpiece conveying hole 42. do. In this state, the conductor trunk 51 is crimped to the conductor section of the feeder line by caulking the conductor trunk 51 from above and below using a suitable die. After this crimping process, the cutting | disconnection between the protrusion part 41 and the cold cathode tube connection part 53 is cut | disconnected by the cutting tool provided with the terminal automatic crimping apparatus. In this way, a feed line in the state where the terminal member T is crimped is obtained.
이 실시형태의 단자부재 연쇄체에서는, 상기한 바와 같이, 연쇄체로부터 각각의 단자부재(T)를 분리하는 절단조작이 1개소에서만 행해진다. 따라서, 절단위치의 오차에 기인하는 단자부재(T)의 전장의 분균형이 억제되기 때문에, 치수정밀도가 양호한 단자부재(T)가 압착된 급전선을 얻을 수 있다. 또한, 각각의 단자부재 (T)를 분리할 때의 절단위치는, 띠형상 연결부재(40)의 폭방향의 위치를 규제함으로써 확실하게 정할 수 있다. 이것에 의해서도, 단자부재(T)의 치수정밀도의 향상을 도모할 수 있다.In the terminal member chain body of this embodiment, as mentioned above, the cutting operation which isolate | separates each terminal member T from a chain body is performed in only one place. Therefore, since the balance of the electric field of the terminal member T resulting from the error of a cutting position is suppressed, the feed line to which the terminal member T with dimensional precision is crimped | bonded can be obtained. In addition, the cutting position at the time of separating each terminal member T can be reliably determined by restrict | limiting the position of the strip | belt-shaped connection member 40 in the width direction. By this, the dimensional accuracy of the terminal member T can be improved.
도 5는, 본 발명의 다른 실시형태에 관한 냉 음극관의 접속구조를 설명하기 위한 사시도이다. 이 도 5에 있어서, 상기 도 1 내지 도 3에 나타낸 각부와 동등한 부분에는, 도 1 내지 도 3의 경우와 동일한 참조부호를 붙여서 나타낸다. 이 실시형태에서는, 급전선(21)의 도체부(21w)에 압착된 단자부재(5A)는, 도체부(21w)의 길이방향에 대해서 거의 직교하는 방향으로 구부림가공된 냉 음극관 접속부(52A)를 보유하고 있다. 이 냉 음극관 접속부(52A)의 관통구멍(53)에 냉 음극관(10)의 리드단자(12)를 관통하여, 이 리드단자(12)와 단자부재(5A)를 땜납 접합함으로써, 상기 제 1의 실시형태의 경우와 마찬가지로 냉 음극관 어셈블리를 양호한 작업성으로 조립할 수 있다.5 is a perspective view for explaining a connection structure of a cold cathode tube according to another embodiment of the present invention. In FIG. 5, the same parts as those shown in FIGS. 1 to 3 are denoted by the same reference numerals as in the case of FIGS. In this embodiment, the terminal member 5A squeezed to the conductor portion 21w of the feed line 21 is connected to the cold cathode tube connecting portion 52A bent in a direction substantially perpendicular to the longitudinal direction of the conductor portion 21w. Holds. The lead terminal 12 of the cold cathode tube 10 penetrates the through hole 53 of the cold cathode tube connecting portion 52A, and the lead terminal 12 and the terminal member 5A are solder-bonded to each other so that the first hole can be soldered. As in the case of the embodiment, the cold cathode tube assembly can be assembled with good workability.
이 실시형태의 구성에서는, 냉 음극관 접속부(52A)가 도체용 몸통(51)에 대해서 거의 직각으로 구부려져 있음으로써, 급전선(21)을 냉 음극관(21)의 길이방향을 따르는 방향으로 인출할 수 있다. 도 5의 예에서는, 급전선(21)은, 몸통(11)로부터 이반하는 방향으로 인출되어 있지만, 리드단자(12)를 도 5의 경우와는 반대측으로부터 관통구멍(53)에 관통되게 함으로써, 급전부(21)를 밸브(11)의 중앙을 따르는 방향으로 인출된 자세로 리드단자(12)에 접속할 수 있다.In the structure of this embodiment, since the cold cathode tube connection part 52A is bent at substantially right angle with respect to the trunk | drum 51 for conductors, the feed line 21 can be drawn out in the direction along the longitudinal direction of the cold cathode tube 21. have. In the example of FIG. 5, the feed line 21 is pulled out in the direction opposite to the body 11, but the feed terminal 21 penetrates the through hole 53 from the side opposite to the case of FIG. The entirety 21 can be connected to the lead terminal 12 in a posture drawn out in the direction along the center of the valve 11.
이상, 본 발명의 2개의 실시형태에 관해서 설명하였지만, 본 발명은 다른 형태로 실시할 수 있다. 예컨대, 상기 실시형태에서는, 곧은 관형상의 밸브 (11)를 보유하는 냉 음극관을 예로 들었지만, 가령, U자 형상 등의 다른 형상의 냉 음극관에 대해서도 본 발명을 적용할 수 있다. 또한, 액정표시패널에서는, 필요한 휘도를 확보하기 위하여, 2개의 냉 음극관이 병렬설치되어서 이용되는 경우가 있지만, 이와 같은 형태의 백라이트용 광원에 대해서도 본 발명을 적용할 수 있다.As mentioned above, although two embodiment of this invention was described, this invention can be implemented with another aspect. For example, in the said embodiment, although the cold cathode tube which has the straight tubular valve 11 was mentioned as an example, the present invention can be applied also to the cold cathode tube of other shapes, such as a U-shape. In addition, in the liquid crystal display panel, two cold cathode tubes may be used in parallel in order to secure necessary luminance. However, the present invention can also be applied to such a backlight light source.
또한, 상기 제 2의 실시형태에서는, 도체용 몸통(51)에 대해서 냉 음극관 접속부(52)가 거의 직각으로 절곡된 예를 나타내었지만, 이 절곡각도는, 90도 미만의 예각을 하여도 좋고, 90도보다 큰 둔각으로 하여도 좋다.In addition, in the said 2nd Embodiment, although the example where the cold cathode tube connection part 52 was bent at substantially right angle with respect to the trunk | drum 51 for conductors was shown, this bending angle may be an acute angle of less than 90 degree | times, The obtuse angle may be larger than 90 degrees.
그 외, 특허청구의 범위에 기재된 사항의 범위에서 설계변경을 실시할 수 있다.In addition, design changes can be made within the scope of the matters described in the claims.
본 발명의 실시형태에 관해서 상세하게 설명했지만, 이들은 본 발명의 기술적 내용을 명확하게 하기 위해서 이용된 구체예에 지나지 않고, 본 발명은 이들 구체예에 한정하여 해석될 필요는 없으며, 본 발명의 정신 및 범위는 첨부한 청구범위에 의해서만 한정된다.Although embodiment of this invention was described in detail, these are only the specific examples used in order to clarify the technical content of this invention, and this invention is not limited to these specific examples, Comprising: The spirit of this invention And scope is defined only by the appended claims.
