제5(a)도, 제5(b)도는 코일조정전과 조정후의 상태를 나타낸 측면도이다.5 (a) and 5 (b) are side views showing states before and after coil adjustment.

본 고안은 텔리비젼튜너등에 사용되는 코일에 관한 것이며, 특히 동조주파수의 조정이 용이하며 코일형상의 파괴가 적고, 진동등에 의한코일의 흔들림이 적은 것을 제공하는데 있다.The present invention relates to a coil used in a television tuner and the like, and in particular, provides easy adjustment of the tuning frequency, less breakage of the coil shape, and less vibration of the coil due to vibration.

종래의 텔리비젼 튜너에 사용되는 코일은 제2(a)도에 나타낸 바와같이, 절연피복을 한 금속선을 밀착 권회한 코일(L)을 사용한다든가 또는 제3(a)도에 나타낸 것처럼 절연피복을 한 금속선을 성기게 감은(간격을 유지하여 감은 것) 코일(L)을 사용하여 이것을 제1도와 같이 텔리비젼튜너(1)의 웨이퍼(2)에 부착하고, 이 코일(L)의 권선부분(3)의 선간의 간격을 넓히거나 좁혀서 동조주파수의 조정을 행하는 것이었다.Coils used in conventional television tuners may use coils L wound tightly on an insulated coating metal wire as shown in FIG. 2 (a) or insulated coating as shown in FIG. 3 (a). Using a coil L wound around a metal wire (coated at intervals), it is attached to the wafer 2 of the television tuner 1 as shown in FIG. 1, and the winding portion 3 of this coil L is The tuning frequency was adjusted by increasing or decreasing the interval between the lines.

그러나 전자의 밀착하여 감은 코일(L)은 조정시, 권선부분(3)의 선간의 간격이 넓어지므로, 제2(b)도와 같이 취부단자(4), (4)를 기부(基部)로 하여 중앙부가 부풀어 올라 코일(L)형상의 파괴를 일으킴과 동시에 기계적으로 불안정하게 되고, 진동등에 의한 코일이 흔들림이 크고, 하울링현상을 일으키는 결점이 있을뿐만이 아니라 코일(L)의 흔들림을 없애기 위하여 접착제를 도포해야하며, 또 후자의 성기게감은 코일(L)은 권선부분(3)의 스프링백이크고, 조정시에 있어서 선간의 간격을 넓히거나 혹은 좁혀서 최량의 동조점에서 조정구(凋整具)를 제거하여도 스프링백에 의해 권선부분(3)의 간격폭이 크고 동조점이 엇갈려서 조정이 곤란하고, 조정에 숙련을 요할 뿐만이 아니라 권선부분(3)의 선간의 간격은 넓혀진 곳의 부분의 선간은 접근하지만 종합적으로는 주파수의 조정범위(인덕턴스의 가변범위)가 적어지며 조정에 시간이 걸린다는 결점이 있다.However, the coil L wound by close contact with the electrons has a wider distance between the wires of the winding part 3 during adjustment. Thus, as shown in FIG. 2 (b), the mounting terminals 4 and 4 are used as bases. The central part swells up, causing coil L shape breakage and mechanical instability. The coil is shaken by vibrations, and there is a flaw that causes howling, as well as the adhesive to remove the shake of coil L. In addition, the latter coarse coil (L) has a large spring back of the winding part (3), and at the time of adjustment, the gap between the lines is widened or narrowed to remove the adjusting tool at the best tuning point. Even though the gap width of the winding part 3 is large and the tuning point is staggered by spring back, adjustment is difficult and not only requires skill in adjustment, but also the distance between the parts of the part where the winding part 3 is widened approaches. comprehensively Has the disadvantage that the adjustment range of frequency (variable range of inductance) is small and adjustment takes time.

본 고안은 상기한 종래의 결점을 해소하려고 한 것으로서, 이러한 본 고안을 제4도, 제5도에 나타낸 실시예에 의거하여 설명하면, (L)은 코일전체를 나타내며, 코일은 양단에 취부단자(4), (4)를 중앙에 권선부분(3)을 설치함과 동시에 권선부분(3)은 중앙부를 성기게 감은 부분(6)으로 하고, 양측에 밀착되게 감은 부분(7), (7)을 설치한 구성으로 하여 코일(L)은 취부단자(4), (4)가 텔리비젼튜너(1)의 웨이퍼(2)에 취부되어 있다.The present invention is intended to solve the above-described drawbacks. When the present invention is described based on the embodiments shown in Figs. 4 and 5, (L) denotes the entire coil, and the coil is mounted at both ends. (4), (4) is installed in the center of the winding section (3) and the winding section (3) is the coarse winding portion (6) in the center portion, the winding portion (7), (7) in close contact with both sides ), The mounting terminals 4 and 4 are mounted on the wafer 2 of the television tuner 1.

또 이 코일(L)의 조정은 제5(b)도에 나타낸 것처럼 권선부분(3)의 성기게 감은 부분(6)에 가까운 밀착되게 감은 부분(7)의 선간의 간격을 조정구등으로 넓힘으로써 행하여지며, 그리고 코일(L)은 밀착되게 감은 부분(7)을 넓히기 때문에 스프링백도 적고, 인덕턴스의 가변범위가 커져 조정작업이 용이하고, 또한 밀착되게 감은 부분(7)의 넓혀진 부분은 성기게 감은 부분(6)측으로 변위되므로 코일(L)의 형상의 파괴가 적고 기계적으로도 안정하고 진동등에 의한흔들림이 적으며, 하우링현장이 적어져서 접착제를 사용하지 않아도 충분히 견딜수 있으나 필요에 따라서는 접착제를 사용하여도 좋다.The coil L is adjusted by widening the interval between the lines of the closely wound portion 7 close to the roughly wound portion 6 of the winding portion 3 as shown in FIG. And the coil (L) widens the close wound portion (7) because there is less springback, the inductance variable range is large, easy to adjust, and the widened portion of the closely wound portion (7) is wound roughly It is displaced to the part 6 side, so the shape of the coil L is less destroyed, mechanically stable, less vibration is caused by vibration, etc., and the howling field is small, so it can withstand the need without using adhesive, but if necessary, adhesive is used. You may also do it.

즉 본 고안에 의하여 권선부분(3)의 선간의 간격을 넓히거나 좁혀서 조정을 행함에 있어서, 코일(L)의 권선부분(3)은 중앙부를 성기게 감은 부분(6)으로 하고, 그 양측에 밀착되게 감은 부분(7), (7)을 설치하여 구성한 것이므로 동조주파수의 조정이 용이하고 작업성이 좋으며, 또 코일(L)형상의 파괴가 적고, 진동등에 의한 코일(L)의 흔들림이 적은 고성능의 코일을 얻을수 있는 것이 특징이다.In other words, in the present invention, the winding portion 3 of the coil L is formed to be the portion 6 wound coarse in both sides of the coil L. It is composed of the parts (7) and (7) wound tightly, so it is easy to adjust the tuning frequency, workability is good, and there is little breakage of the coil L shape, and the vibration of the coil L due to vibration is small. It is characterized by high performance coils.
