본 고안은 UHF, VHF가 일체로 조합되어진 전자동조튜너에 관련된 것으로서, 이는 특히 UHF튜너측의 입력 부트리머판 미조구조에 관한 것이다.The present invention relates to a fully tuned tuner in which UHF and VHF are integrally combined, and more particularly, relates to an input boot reamer plate structure on the UHF tuner side.

일반적인 UHF, VHF 일체형 전자동조튜너에서 분포정수회로방식의 UHF 입력측 구조는 입력동조, 단간동조, 발진회로의 리액턴스값을 철편형트리머를 이용하여서 되고 이는 제 1 도와 같은 예의 구성으로 되어 있다.In the general UHF and VHF integrated tuner, the UHF input side structure of the distribution constant circuit method is made of the iron trimmer for reactance values of the input tuning, inter-stage tuning, and oscillation circuit.

즉, 여기서는 금속틀(12)내측에 실드판(14)과 프린트기판(15)이 고정되어지고, 이 프린트기판(15)에는 트리머판(11)이 연설되어진 중심도체(13)가 복수개의 격실에 각기 배치되어져서 상기 중심도체(13)가 UHF공진회로의 일부로서 사용되어진다.That is, in this case, the shield plate 14 and the printed board 15 are fixed to the inner side of the metal frame 12, and the printed circuit board 15 has a plurality of compartments including a central conductor 13 on which the trimmer plate 11 is extended. The center conductor 13 is used as part of the UHF resonant circuit, respectively.

그리고, 이러한 중심도체(13)와 트리머판(11)은 기판(15)의소정개소에 각기 천설한 취부구멍에 1매씩 삽입하여 납땜 처리에 의해 고정되어지고, RF회로의 응답특성조정시 그 미세조정(이하 편의상 미조라 약칭한다)을 위해 중심도체(13)로부터 연설되어진 트리머판(11)을 조정집게등을 이용한 미조정을 행하게 된다.Then, the center conductor 13 and the trimmer plate 11 are inserted into each of the mounting holes formed in the predetermined positions of the substrate 15 and fixed by soldering, and are finely adjusted when adjusting the response characteristics of the RF circuit. For adjustment (hereinafter abbreviated as Mizo for convenience), the trimmer plate 11 that is delivered from the center conductor 13 is fine-tuned using an adjustment forceps.

그러나, 상기 트리머판(11)을 미조정할시에는 중심도체(13)까지 연동하므로 어느 특정부위를 조정하면 타부위가 변경되어서는 현상이 생겨 수차례 미세조정이 행하여져야만 한다는 불편함이 있었다.However, when the trimmer plate 11 is finely adjusted, the center conductor 13 is interlocked. Therefore, if any particular portion is adjusted, the other portion may be changed, which may cause inconvenience.

본 고안의 목적은 상기와 같은 종래 기술의 결점을 해소하고 그 조정작업이 용이하게 이뤄질 수 있는 UHF튜너 입력측 트리머판 미조구조를 제공하는데 있다.An object of the present invention is to provide a UHF tuner input side trimmer plate microstructure that can solve the above-mentioned drawbacks of the prior art and can be easily adjusted.

이러한 목적을 달성하기 위한 본 고안은 금속틀내의 트리머판과 대향된 실드판측의 소정 개소에 트리머판 미조구조를 마련하여 중심도체측에의 트리머판을 이용하여 미조할 필요가 없는 구성을 그 특징으로 하는 것이다.The present invention for achieving the above object is characterized by the configuration that does not need to be trimmed by using a trimmer plate on the center conductor side by providing a trimmer plate rough structure at a predetermined position on the shield plate side facing the trimmer plate in the metal frame. It is.

이하에서 이를 좀더 상세히 설명하면 다음과 같다.This will be described in more detail below.

제 2 도는 본 고안의 미조구조가 마련된 실드판(14)을 나타내고 있다. 즉 여기서는 중심도체(13)의 일측으로부터 연설되어진 트리머판(11)의 평판부와 대향된 위치에의 장방형 미조편(1)이 실드판(14)측의 삭설홈(1b)으로 형성되어진다.2 shows the shield plate 14 provided with the structure of the present invention. In other words, here, the rectangular micro-pieces 1 at positions opposed to the flat plate portions of the trimmer plate 11 protruded from one side of the center conductor 13 are formed as cutting grooves 1b on the shield plate 14 side.

또, 상기 미조편(1)에는 조정집게등의 핀홀(1a)을 천설한 것으로 할 수도 있다. 이러한 구성에 본 고안은 UHF튜너측의 RF회로 응답특성조정시 그 미조를 행할때는 중심도체(13)일측으로부터 연설 되어진 트리머판(11)의 평판부와 대향된 위치의 미조편(1)을 소망하는데로 움직여서 그 특성조정을 행하면 된다.In addition, the fine piece 1 may be provided with pinholes 1a, such as adjusting forceps. In this configuration, the present invention desires an uncoated piece (1) at a position opposite to the flat portion of the trimmer plate (11) that is spoken from one side of the center conductor (13) when the RF circuit response characteristic of the UHF tuner is adjusted. You can move to and adjust the characteristics.

이러한 본 고안에 의해서는 UHF회로특성조정시 중심도체의 트리머판을 움직일 필요가 없으므로 그 UHF튜너의 특성안정화와, 조정작업의 용이성으로 인한 원가절감도 기할수 있는 유익한 특징이 있는 것이다.According to the present invention, it is not necessary to move the trimmer plate of the center conductor when adjusting the characteristics of the UHF circuit, and thus, there is an advantageous feature to stabilize the characteristics of the UHF tuner and reduce the cost due to the ease of adjustment.
