Abstract

본 발명은 길이방향으로 관통구멍을 형성한 후 일측 단부면인 개방면을 제외한 전체 표면에 전극을 도포한 유전체 몸체로 이루어진 공진기가, 개방면측 관통구멍으로 장착된 입출력 단자를 매개로 인쇄회로 기판에 연결됨으로서 형성되는 유전체 필터에 관한 것으로, 상기 입출력 단자는 개방면의 인쇄회로기판측 모서리를 감싸면서 구부러져 그 단부가 몸체와 인쇄회로기판의 사이에 위치하고, 상기 입출력 단자의 연결 꼬리가 위치하는 부분의 외포면 전극은 제거됨을 특징으로 하여, 공진기가 이루는 전체의 길이를 종래보다 작게 하고 그 공진기의 장착 면적을 줄여 유전체 필터의 크기를 소형화 할 수 있다.The present invention is characterized in that a through hole is formed in the longitudinal direction and then a resonator formed of a dielectric body having an electrode on an entire surface excluding an open end which is an end surface is connected to a printed circuit board Output terminal is bent while being wrapped around the side of the printed circuit board on the open side, and the end of the bent portion is positioned between the body and the printed circuit board, and a portion where the connection tail of the input / output terminal is located The size of the dielectric filter can be reduced by reducing the overall length of the resonator and reducing the mounting area of the resonator.

Description

유전체 필터의 공진기The resonator of the dielectric filter

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제 3 도는 본 발명에 따른 유전체 필터를 도시한 정단면도로서,3 is a front sectional view showing a dielectric filter according to the present invention,

제 3a도는 공진기를 직접 인쇄회로기판에 장착하는 경우.Figure 3a shows the case where the resonator is mounted directly on the printed circuit board.

제 3b도는 공진기를 기판형 캐패시터를 개재하여 인쇄회로기판에 장착하는 경우.Fig. 3b shows a case where the resonator is mounted on a printed circuit board via a substrate-type capacitor.
