본 고안은 음극선관 고정용 러그(LUG)에 관한 것으로 특히 TV 혹은 모니터(Monitor)의 샤시에 음극선관을 장착함에 있어서, 기구적인 정합 차이에 의한 샤시와 음극선관 사이의 틈새를 적절하게 조정할 수 있도록 함과 아울러 미끄러짐 현상을 방지할 수 있도록 한 음극선관 고정용 러그(LUG)에 관한 것이다.The present invention relates to a cathode ray tube fixing lug (LUG), in particular in the case of mounting the cathode ray tube on the chassis of a TV or monitor, so that the gap between the chassis and the cathode ray tube due to the mechanical matching difference can be properly adjusted. In addition, the present invention relates to a cathode ray tube fixing lug (LUG) capable of preventing slippage.
일반적인 음극선관의 장착구조가 제1도 및 제2도에 도시되어있는 바, 이를 간단히 살펴보면 다음과 같다.The mounting structure of a typical cathode ray tube is shown in FIGS. 1 and 2, which will be briefly described as follows.
도시한 바와 같이, 음극선관(1)은 러그(2)라는 고정 부재에 의해 샤시(3)에 고정되어 있다.As shown, the cathode ray tube 1 is fixed to the chassis 3 by a fixing member called a lug 2.
부연하면, 일측이 음극선관(1)에 결합되는 러그(2)의 나사공(2a)을 샤시(3)에 형성된 보스(4)의 나사공(4a)에 일치시킨 후, 나사(5)등을 이용하여 상기 음극선관(1)을 샤시(3)에 장착 고정하는 것이다.In other words, after one side of the lug 2 coupled to the cathode ray tube 1 coincides with the screw hole 4a of the boss 4 formed in the chassis 3, the screw 5 or the like. Using to fix the cathode ray tube 1 to the chassis (3).
상기 러그(2)는 통상 음극선관(1)의 네모서리에 각각 1개씩 장착되어 있으며, 제3도에 도시한 바와같이 두께 약 1㎜ 내외의 아연 강판재를 소정의 길이로 절단된 후, 일측부에 나사공(2a)을 형성하여 L자형으로 절곡 형성한 구조로 되어 있다.One lug 2 is mounted to each of the four corners of the cathode ray tube 1, and as shown in FIG. 3, after cutting the zinc steel sheet having a thickness of about 1 mm to a predetermined length, The screw hole 2a is formed in the side part, and it is a structure which bend | folded and formed in L shape.
또한, 상기 러그(2)는 음극선관(1)과 샤시(3)와의 틈새(α)를 최소화시켜 주기 위해 제4도에 도시한 바와같이 음극선관(1)이 중심에서 소정 거리(a)에 위치 설정되어 있는 기준점(b)과 러그(2) 상단부와의 간격(Zo)을 4개소 러그(2)들 상호간의 가능한 범위내에서 일치시켜 주고 있다. 이를 통칭 Zo점 관리기준치라 하고 있으며 음극선관(1)에 러그(2)를 장착시키는 공정상의 어려움으로 인하여 통상 4개소의 러그(2)들 상호간에는 어느정도(1∼2㎜)의 공차를 허용하고 있는 실정에 있다.In addition, the lug 2 has the cathode ray tube 1 at a predetermined distance a from the center as shown in FIG. 4 in order to minimize the gap α between the cathode ray tube 1 and the chassis 3. The distance Zo between the positioned reference point b and the upper end of the lug 2 is matched within the possible range between the four lugs 2. This is commonly referred to as the Zo point management reference value, and due to the difficulty in attaching the lug 2 to the cathode ray tube 1, a tolerance of a certain degree (1 to 2 mm) is generally allowed between four lugs 2. There is a situation.
이러한 이유로 허용하고 있는 공차는 샤시(3)에 음극선관(1)을 조립할 때, 상기 샤시(3)와 음극선관(1)의 사이에 틈새(α)를 발생시키는 주요인으로 작용하고 있으며, 이와같은 틈새(α)는 TV 혹은 모니터 셋트(Monitor Set)의 외관을 해칠 뿐만아니라 사용자의 실수 등으로 인해 물등의 액체가 샤시(3)의 내부로 인입될 가능성이 있고, 이에 따라 각종 회로에 치명적인 손상을 끼칠 수 있는 결함이 있었다.For this reason, the allowable tolerance acts as a main factor in generating a gap α between the chassis 3 and the cathode ray tube 1 when assembling the cathode ray tube 1 to the chassis 3. The gap α not only impairs the appearance of the TV or monitor set, but may also cause liquid such as water to enter the chassis 3 due to a user's mistake, thereby causing a fatal damage to various circuits. There was a defect that could be caused.
뿐만아니라 러그(2)의 보스(4) 접촉 부위가 평면으로 되어 있고 탄력성이 없는 관계로 조립시 러그(2)와 보스(4) 사이에 고무링(도시되지 않음) 및 와샤(도시되지 않음)류등을 추가 사용하여 두기구물간, 즉 러그(2)와 샤시(3)간의 미끄러짐을 방지시켜 주는 등 공정상의 번거로움도 있었다.In addition, since the contact portion of the boss 4 of the lug 2 is flat and has no elasticity, a rubber ring (not shown) and a washer (not shown) are provided between the lug 2 and the boss 4 when assembled. The use of additional materials, such as preventing the slip between the two components, that is, the lug (2) and the chassis (3) was also a cumbersome process.
본 고안은 상기한 바와 같은 종래 러그가 가지는 결함을 해소하기 위하여 안출한 것으로, 러그를 종래의 L형 구조에서 샤시에 구비된 보스와의 접촉부위를 재절곡 형성하여 체결 압력과 두절곡 평면간의 간격으로 Zo치를 적절하게 조절할 수 있도록 함과 아울러 두절곡 평면간의 탄력에 의해 러그와 보스와의 미끄러짐을 방지할 수 있도록 한 것인 바, 이를 첨부한 도면에 의하여 보다 상세히 설명하면 다음과 같다.The present invention devised to solve the defects of the conventional lugs as described above, the lug is formed in the conventional L-shaped structure by re-bending the contact portion with the boss provided in the chassis, the gap between the clamping pressure and the bending plane In order to be able to properly adjust the Zo value as well as to prevent the slip between the lug and the boss by the elasticity between the two bending plane, as described in more detail by the accompanying drawings as follows.
즉, 본 고안에 의한 음극선관용 러그는 제5도 및 제6도에 도시한 바와 같이 샤시 (3)의 보스(4)와 접촉되는 러그(10)의 접촉 부위(10a)(10b)를 재절곡 형성하여 겹면으로 형성한 것으로, 실제 러그(10)의 두절곡평면(10a)(10b)이 샤시(3)의 보스와 결합하도록 한 것이며, 각 절곡평면(10a)(10b)간의 간격(β)은 최소 Zo점 관리규격인 1㎜이상 유지될 수 있도록 되어 있다.That is, the lug for cathode ray tube according to the present invention, as shown in FIGS. 5 and 6, re-bending the contact portions 10a and 10b of the lug 10 in contact with the boss 4 of the chassis 3. It is formed to form a lap surface, the actual bending surface 10a (10b) of the lug 10 is to be combined with the boss of the chassis 3, the interval (β) between each bending plane (10a) (10b) The minimum Zo point can be maintained above 1mm.
상기 러그(10)의 재질은 일정 수준 이상의 탄력성을 가진 것을 사용할 수 있으며, 그 재질을 이에 꼭 한정할 필요는 없다.The material of the lug 10 may be used having a certain level or more of elasticity, it is not necessary to limit the material thereto.
도면에서 종래 구성과 동일한 부분에 대해서는 동일 부호로 표시하였다.In the drawings, the same parts as in the conventional construction are denoted by the same reference numerals.
이와 같이 구성된 본 고안에 의한 음극선관용 러그를 이용하여 음극선관(1)을 샤시(3)에 장착 고정하는 과정 즉, 음극선관(1)에 부착된 러그(10)의 나사공(10c)을 샤시(3)에 형성된 보스(4)의 나사공(4a)에 일치시킨 후, 나사(5)를 이용하여 장착 고정하는 과정은 종래와 동일 유사하나, 본 고안은 러그(10)를 샤시(3)의 보스(4)에 나사(5)를 이용하여 체결할때 제6도에 도시한 바와같이, 두 절곡평면(10a)(10b)간의 간격β 범위내에서 체결압력의 적정 안배로 틈새(α)발생요인인 Zo치를 소정의 보정량(△)으로 보정시켜줄 수 있을 뿐만아니라, 상기 두절곡 평면(10a)(10b)간의 탄력에 의해 러그(10)와 보스(4)와의 미끄러짐 현상을 방지할 수 있는 것이다.The process of fixing the cathode ray tube 1 to the chassis 3 using the cathode ray tube lug according to the present invention configured as described above, that is, the screw hole 10c of the lug 10 attached to the cathode ray tube 1 is fixed to the chassis. After matching the threaded hole (4a) of the boss (4) formed in (3), the process of mounting and fixing using the screw (5) is similar to the conventional one, but the present invention is the lug (10) to the chassis (3) As shown in FIG. 6, when tightening with the screw 4 to the boss 4 of the boss 4, the clearance α with an appropriate arrangement of the tightening pressure within the range β between the two bent planes 10a and 10b. Not only can the Zo factor, which is a generation factor, be corrected to a predetermined correction amount △, but also the slippage between the lug 10 and the boss 4 can be prevented by the elasticity between the two bending planes 10a and 10b. will be.
이상에서 설명한 바와같이, 본 고안에 의한 음극선관 고정용 러그에 의하면, 샤시와 음극선관 사이의 틈새를 제거시켜 주므로 TV 및 모니터의 외관 품질 향상을 기할 수 있을 뿐만아니라 사용자의 실수등에 의한 회로의 치명적인 손상을 방지할 수 있는 효과가 있다.As described above, according to the cathode ray tube fixing lug according to the present invention, the gap between the chassis and the cathode ray tube is eliminated, so that the appearance quality of the TV and the monitor can be improved, and the circuit of the circuit caused by the user's mistake can be caused. It has the effect of preventing damage.
또한, 샤시 조립시 별도의 와샤 및 고무링등의 삽입 고정이 불필요하므로 조립 공정을 단순화시킬 수 있는 효과가 있다.In addition, since it is unnecessary to insert and fix a separate washer and rubber ring when assembling the chassis, there is an effect of simplifying the assembly process.
