본 발명은 전기부품의 취부방법, 상술한다면, 프린트기판에 전기부품을 취부할 때에 전기부품의 취부 위치부근에 예를들면 전기부품의 조정용등의 개공(開孔)을 프린트기판에 설치할 필요가 있는 전기부품의 프린트 기판에의 취부방법에 관하여 침지(浸漬) 납땜공정에서 발생하는 열, 용제의 소상(遡上) 등에서 전기 부품을 보호하는 것을 목적으로 한다.The present invention provides a method of mounting an electrical component, and if it is described above, when attaching the electrical component to a printed circuit board, it is necessary to install a hole in the printed circuit board near the mounting position of the electrical component, for example, for adjusting the electrical component. An object of the present invention is to protect an electrical component from heat generated in an immersion soldering process, a small phase of a solvent, and the like, on the method of mounting the electrical component on a printed board.

이 종류의 전기부품의 취부구조에는 예를들면 소형의 가변콘덴서의 취부구조가 있다. AM방송 동조용등에 이용되는 상기의 소형가변콘덴서는, 그단자 및 조작축을 동일방향으로 돌출시켜 놓고, 이 가변 콘덴서를 프린트 기판에 취부 후, 프린트 기판의 개공에 대향한 상기 조작축을 프린트 기판의 이면측에서 조작하도록 하여 소형가변 콘덴서 탑재기기의 스페이스 팩터의 향상과 취부 작업성의 향상을 도모하고 있다.The mounting structure of this kind of electric component includes, for example, a mounting structure of a small variable capacitor. The small variable capacitor used for AM broadcasting tuning, etc. protrudes the terminal and the operation shaft in the same direction, attaches the variable capacitor to the printed circuit board, and then attaches the operating shaft facing the opening of the printed board to the back of the printed board. By operating from the side, it is possible to improve the space factor and the mounting workability of the small variable capacitor mounted equipment.

그리고, 종래의 이 종류의 전기부품의 취부방법은, 제1도 및 제2도에 나타난 바와 같이, 프린트 기판(1)에 조작축(4)를 조작하기 위한 개공(3)을 미리 친설해 놓고, 소형의 가변콘덴서(2)의 접속용의단자(5), 어스용의 단자(6)를 프린트기판(11)에 각각 삽통하고, 침지납땜(자동납땜)에 의해 프린트 기판(1)의 이면에 도전패턴과 각 단자(5),(6)를 일거에 납땜으로 접속, 고정하고 있었다. 그렇지만 조작축(4) 및 가변콘덴서(2)의 일부가 개공(3)을 사이에 두고 땜납조(槽)에 향해있기 때문에, 제1도시와 같이 조작축(4)에 내열 캡(7)을 씌우던지 제2도시와 같이 개공(3)을 폐쇄하는 내열 테이프(8)을 이용하여 땜납이나 용제가 조작축(4)에 부착하던지, 혹은 축수부(軸受部) 등에서 가변콘덴서(2)의 내부에 침입하여 성능을 약화시키는 것을 방지하고 있었다.In the conventional method for attaching an electric component of this type, as shown in FIGS. 1 and 2, the opening 3 for operating the operation shaft 4 on the printed board 1 is provided in advance. The terminal 5 for connection of the small variable capacitor 2 and the terminal 6 for earth are respectively inserted into the printed circuit board 11, and the back surface of the printed circuit board 1 is immersed (automatic soldering). The conductive patterns and the terminals 5 and 6 were connected to each other by soldering and fixed. However, since a part of the operating shaft 4 and the variable capacitor 2 faces the solder bath with the opening 3 interposed therebetween, the heat resistant cap 7 is attached to the operating shaft 4 as shown in FIG. The solder or the solvent adheres to the operation shaft 4 using the heat-resistant tape 8 which closes the opening 3 as shown in FIG. 2, or the inside of the variable capacitor 2 in the bearing part. It was prevented from infiltrating and degrading performance.

따라서, 납땜 전에, 내열 캡(7) 혹은 내열 테이프(8)를 피착(被着)하는 공정과, 납땜후에 캡(7) 혹은 테이프(8)를 떼어내는 공정을 요하고 작업이 번잡하므로, 당초부터 캡 또는 테이프(8) 등의 여분의 부품을 필요한다고 하는 결점이 있었다.Therefore, the process requires the process of depositing the heat-resistant cap 7 or the heat-resistant tape 8 before soldering, and the process of removing the cap 7 or the tape 8 after soldering. There is a drawback that a spare part such as a cap or a tape 8 is required.

본 발명은 상기의 결점을 해소하기 위하여 된 것으로, 이하 본 발명을 제3도∼제5도에 나타난 한 실시예에 의해 설명한다.This invention is made | formed in order to solve the said fault, Hereinafter, this invention is demonstrated by the Example shown to FIG. 3 thru | or FIG.

도면에서(2)는 소형의 가변콘덴서, (4)는 조작축, (5)는 주변회로와의 접속용의단자, (6)은 탄성을 갖는 어스용의단자, (1)는 가변콘덴서 (2)를 취부하기 위한 프린트기판, (9)는 단자(5)를 삽통하기 위한 소공, (10)은 단자(6)를 삽통하기 위한 소공, (11)은 조작축(4)과 대응하는 위치에 설치된 슬릿(12)으로 감싸여진 절제예 정부이다.In the drawing, reference numeral 2 denotes a small variable capacitor, 4 denotes an operation shaft, 5 denotes a terminal for connection to a peripheral circuit, 6 denotes an earth terminal having elasticity, and 1 denotes a variable capacitor ( 2) a printed board for mounting, (9) a hole for inserting the terminal (5), (10) a hole for inserting the terminal (6), (11) a position corresponding to the operation shaft (4) It is a government of restraint wrapped in slits 12 installed in the.

취부에 즈음해서는, 우선 가변콘덴서(2)의 각 단자(5),(6)를 각각 소공(9),(10)에 각각 삽입하고, 가변콘덴서(2)의 대좌부(台座部)(2a)를 프린트기판(1)에 당접시켜 위치결정함과 동시에 어스용의 단자(6)의 절곡부(6a)의 탄력성으로 가변콘덴서(2)를 프린트판기(1)에 가고정 한다. 이때, 조작축(4)은 각 단자(5),(6)보다도 그 돌출길이를 짧게 설정하고 있기 때문에, 프린트기판(1)에 당접하는 일은 없다.At the time of attachment, first, each terminal 5, 6 of the variable capacitor 2 is inserted into the small holes 9, 10, respectively, and the pedestal part 2a of the variable capacitor 2 is inserted. ) Is brought into contact with the printed circuit board 1, and the variable capacitor 2 is temporarily fixed to the printed board 1 by the elasticity of the bent portion 6a of the terminal 6 for earth. At this time, since the protruding length of the operation shaft 4 is set shorter than that of the respective terminals 5 and 6, the operation shaft 4 does not contact the printed circuit board 1.

그런뒤, 가변콘덴서(2)와 다른 전기부품(도시하지 않았다)을 재치(載置)한 상기 프린트기판(1)을 벨트컨베이어 등으로 땜납조에 반송하여, 상기 프린트기판(1)의 이면측에 돌출한 각단자(5),(6)와 프린트기판(1)의 이면의 도전패턴(도시하지 않았다)을 땜납(15)으로 접속, 고착한다. 이때, 슬릿(12)의 폭은 대단히 가늘기 때문에 슬릿(12)에서 땜납 및 용제가 프린트기판(1)의 상부에 침입할 우려는 없다. 또, 종래와 같이 개공(3)을 천설한 상태에서 침지납땜을 행하지 않기 때문에 열, 증기등에 의해 프린트기판(1) 윗면에 재치(載置)한 가변콘덴서(2) 및 다른 열등에 민감한 전기부품을 손상하는 일도 없다.Thereafter, the printed circuit board 1 on which the variable capacitor 2 and other electric parts (not shown) are placed is conveyed to a solder tank by a belt conveyor or the like, and then to the rear surface side of the printed board 1. The protruding angular terminals 5 and 6 and the conductive pattern (not shown) on the back surface of the printed board 1 are connected and fixed with solder 15. At this time, since the width of the slit 12 is very thin, there is no fear that the solder and the solvent enter the upper portion of the printed board 1 in the slit 12. In addition, since the immersion soldering is not performed in the state where the opening 3 is laid as in the related art, the variable capacitor 2 placed on the upper surface of the printed circuit board 1 by heat, steam or the like and other sensitive electric parts There is no damage to it.

그리고 상기 슬릿(12)으로 둘러싸인 절제예정부(11)를 슬릿(12)에 적당한 칼등, 드라이버의 선단 등을 취입하여 제거함에 의해 개공(3)을 설치하고, 이 개공(3)을 통하여, 예를들면 상기 조작축(4)에 프리(13)를 고정하면 조립은 종료한다.Then, the opening 3 is provided by removing and removing the ablation preliminary section 11 surrounded by the slit 12 by inserting a suitable knife or the like into the slit 12 and removing the tip of the driver. For example, if the free 13 is fixed to the operation shaft 4, the assembly is completed.

또 전술한 실시예에서는 가변콘덴서(2)(전기부품)의 아래측에 절제예정부(11)를 설치한 예를 설명했지만, 절제예정부(11)를 제6도에 도시한 바와 같이 전기부품(14)의 근방에 설치하는 것도 있고, 슬릿의 형상도 제4도시의 연속한 형상의 슬릿외에, 미싱눈금 모양의 다수 개의 적은 슬릿으로 형성하는 것도 있고 요하건대 절제예정부(11)를 제거하기 쉽게하는 형상이면 좋고, 각종의 변형이 생각되어지는 바이다.In addition, in the above-described embodiment, the example in which the ablation preliminary section 11 is provided below the variable capacitor 2 (electrical component) has been described. However, the ablation preliminary section 11 is shown in FIG. Some may be provided in the vicinity of (14). In addition to the slit of the continuous shape shown in Fig. 4, the slits may be formed of a plurality of small slits in the form of missing scales. It may be a shape that facilitates, and various deformations are considered.

이상 기술한 바와 같이 본 발명에 의하면, 침지납땜시에 절제예정부가, 전기부품을 보호하고 있는 구성이기 때문에 땜납이나 용제가 전기 부품에 부착하거나 납땜시의 열이나 증기로 전기부품을 손상하게 할우려가 없고, 또한 침지 납땜시에 종래와 같이 별개의 보호용의 부품을 필요로 하지 않기 때문에 보호용의 별도 부품을 취부, 제거작업공정에 비해 슬릿에 의해 절제하기 쉽게 되어 있는 절제예정부를 간단히 제거하여 개공을 설치한다고 하는 간단한 한 공정으로 끝나므로, 작업성도 좋다고 하는 실용가치가 큰 효과를 갖는다.As described above, according to the present invention, the ablation preliminary government protects the electrical components during immersion soldering, so that the solder or the solvent adheres to the electrical components, or the heat or steam during the soldering damages the electrical components. In addition, since separate protective parts are not required as in conventional soldering soldering, separate parts for protection can be easily removed by removing the preliminary preliminary section, which is easier to remove by the slit than in the removal process. Since it ends with a simple process of installation, the practical value that workability is also good has a big effect.
