One end of the signal terminal 14 is made is coupled to the fastening hole 18 formed in the PCB substrate 16, the end of the signal terminal 14 protruding to the outside of the fastening hole 18 is the PCB board 16 It is kept fixed by soldering on one side of it.

상기와 같은 종래의 구조에서는 다음과 같은 문제점이 발생하게 되는 바 즉, 튜너로 부터 발신되는 입력신호는 고주파이므로 소우필터와 신호단자 사이로 유기되는 상기의 고주파신호는 소우필터의 고유특성을 떨어뜨리게 되며 따라서 인접채널의 간섭 및 사운드간섭을 유발하는 문제점이 있어왔다.In the conventional structure as described above, the following problems occur, that is, since the input signal transmitted from the tuner is a high frequency, the high frequency signal induced between the saw filter and the signal terminal degrades the unique characteristics of the saw filter. Therefore, there has been a problem of causing interference and sound interference of adjacent channels.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로 소우필터에 발생하는 인접채널의 영상 및 음성주파수 간섭과 함께 소우필터의 단자땜 부위와 소우필터케이스 사이의 간섭을 줄일 수 있는 전자제품용 소우필터의 PCB패턴 구조를 제공함에 고안의 목적이 있는 것이다.The present invention was devised to solve the above problems, and the saw for electronic products which can reduce the interference between the soldering terminal of the saw filter and the saw filter case together with the image and audio frequency interference of the adjacent channel generated in the saw filter. The purpose is to provide a PCB pattern structure of the filter.

상기의 목적을 달성하기 위하여 본 고안은 PCB기판과 고정이 이루어지는 소우필터케이스와 신호단자의 내측으로 피복점프단자를 추가로 설치하되 피복점프단자의 양측끝단은 PCB기판에 형성된 체결공으로 결합하여 돌출된 피복점프단자의 끝단부는 납땜으로 PCB기판의 일측면에 고정시킨 것으로 이하 첨부된 도면을 통하여 본 고안을 상세히 설명하면 다음과 같다.In order to achieve the above object, the present invention additionally installs the jump filter case which is fixed to the PCB substrate and the inside of the signal terminal and the signal terminal, but both ends of the coated jump terminal are coupled to each other by a fastening hole formed on the PCB substrate. The end of the coated jump terminal is fixed to one side of the PCB by soldering. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안 전자제품용 소우필터의 PCB패턴 구조의 설치상태도를 나타낸다.Figure 1 shows the installation state of the PCB pattern structure of the saw filter for electronic products of the present invention.

PCB패턴구조는 PCB기판(16)의 상부로 소우필터(10)가 내장된 소우필터케이스(12)가 신호단자(14) 및 피복점프단자(100)에 의하여 연결설치되어 이루어진다.The PCB pattern structure is formed by connecting the saw filter case 12 having the saw filter 10 to the upper portion of the PCB 16 by the signal terminal 14 and the coated jump terminal 100.

전체적인 구조는 전술한 제2도 에서와 동일하게 되나 소우필터케이스(12)와 PCB기판(16)의 사이로 피복점프단자(100)가 추가로 설치되어 있다.The overall structure is the same as in FIG. 2, but the cover jump terminal 100 is additionally provided between the saw filter case 12 and the PCB substrate 16. FIG.

피복점프단자(100)의 일측면은 소우필터케이스(12)와 밀착상태를 유지하고 있으며 피복점프단자(100)의 타측면은 PCB기판(16)의 상부일측면과 밀착상태를 유지하고 있다.One side of the coated jump terminal 100 maintains close contact with the saw filter case 12, and the other side of the covered jump terminal 100 maintains close contact with the upper one side of the PCB substrate 16.

피복점프단자(100)의 양끝단은 PCB기판(16)에 형성된 체결공(20)과 결합상태를 유지하고 있으며 체결공(20) 외측으로 돌출된 피복점프단자(100)의 끝단부는 PCB기판(16)과 납땜에 의하여 고정상태를 유지하고 있다.Both ends of the coated jump terminal 100 maintain the coupling state with the fastening hole 20 formed in the PCB substrate 16, and the end of the coated jump terminal 100 protruding outward from the fastening hole 20 is the PCB substrate ( 16) and it is fixed by soldering.
