일반적으로 튜너의 섀시는 종이 에폭시 또는 유리 에폭시계의 판 위에 동박을 입혀서 필요한 회로를 인쇄하고 그 이외의 부분은 제거한 후 다수 개의 코일 및 콘덴서, 그리고 IC 칩 등을 부착하여 소정의 동조기능을 수행하는 인쇄회로기판을 지지·고정하는 수단으로 이용된다.In general, the tuner's chassis is printed on a sheet of paper-epoxy or glass-epoxy-based plate to print the necessary circuit, and removes the other parts, and then attaches a plurality of coils, capacitors, and IC chips to perform a predetermined tuning function. Used as a means for supporting and fixing a printed circuit board.
도 1은 종래 기술에 따른 튜너의 섀시를 나타내는 인쇄회로기판을 포함한 사시도이다.1 is a perspective view including a printed circuit board showing a chassis of a tuner according to the prior art.
도 1에 나타낸 바와 같이, 종래 기술에 따른 튜너의 섀시(10)는 인쇄회로기판의 면적에 대응하는 크기를 가지며 코킹편(21)이 형성된 외측 섀시부(20)와, 상기 외측 섀시부(20)의 내부에 구비되어 인쇄회로기판의 하면을 지지하며 상기 인쇄회로기판에 성형된 고정구멍에 끼워지는 고정핀(31)이 형성된 내측 섀시부(30)로 이루어진다.As shown in FIG. 1, the chassis 10 of the tuner according to the related art has an outer chassis 20 having a size corresponding to the area of a printed circuit board and having a caulking piece 21 formed therein, and the outer chassis 20. The inner chassis portion 30 is formed in the inner chassis portion 30 to support the lower surface of the printed circuit board and to have a fixing pin 31 fitted into the fixing hole formed in the printed circuit board.
이때, 상기 외측 섀시부(20)의 코킹편(21)은 코킹시 인쇄회로기판의 상면에 면 접촉될 수 있도록 세로방향으로 이루어진다.At this time, the caulking piece 21 of the outer chassis 20 is made in the longitudinal direction so as to be in surface contact with the upper surface of the printed circuit board when caulking.
상기 구성으로 이루어진 종래 기술에 따른 튜너의 섀시의 결합동작을 설명하면 다음과 같다.Referring to the coupling operation of the chassis of the tuner according to the prior art made of the above configuration as follows.
먼저, 섀시(10) 위에 결합시키고자 하는 인쇄회로기판을 위치시킨 후, 내측 섀시부(30)에 돌출 성형된 고정핀(31)이 인쇄회로기판의 고정구멍에 끼워질 수 있도록 인쇄회로기판을 상기 섀시(10)의 내측 섀시부(30) 위에 안착시킨다.First, after placing the printed circuit board to be bonded on the chassis 10, the printed circuit board is mounted so that the fixing pin 31 protrudingly formed in the inner chassis portion 30 can be fitted into the fixing hole of the printed circuit board. It rests on the inner chassis portion 30 of the chassis 10.
그 후, 코킹기를 이용하여 섀시(10)의 외측 섀시부(20)에 구비된 코킹편(21)을 내측으로 코킹하여 절곡시키고 납땜함으로써 인쇄회로기판을 섀시(10)에 고정하게 된다.Thereafter, the caulking piece 21 provided in the outer chassis 20 of the chassis 10 is caulked, bent, and soldered to the inside of the chassis 10 to fix the printed circuit board to the chassis 10.
그런데, 종래 기술에 따른 튜너의 섀시(10)는 코킹편(21)을 절곡시키기 위하여 코킹기를 사용하므로 작업시간이 길어짐은 물론 설비추가로 인한 생산비용이 높아지고, 리플로우(reflow) 작업 후 코킹부에 냉땜이 발생하는 문제점이 있었다.By the way, the chassis 10 of the tuner according to the prior art uses a caulking machine to bend the caulking piece 21, so that the work time is long, as well as the production cost due to the addition of equipment, caulking unit after the reflow operation There was a problem in that cold soldering occurred.
본 발명은 종래 기술의 문제점을 해결하기 위하여 제안된 것으로서, 그 목적으로 하는 바는 외측 섀시부의 내측에 돌출 성형되어 인쇄회로기판을 끼움 고정할 수 있도록 한 엠보싱을 형성함으로써 코깅기 및 납땜작업 없이 인쇄회로기판을 섀시에 견고하게 고정되도록 하여 작업의 생산성을 향상시키고 코킹부에 발생하는 냉땜을 없애도록 하는데 있다.The present invention has been proposed to solve the problems of the prior art, and its object is to print without cogging and soldering work by forming an embossing that is protruded to the inside of the outer chassis to fix the printed circuit board. The circuit board is firmly fixed to the chassis to improve the productivity of the work and to eliminate the cold solder generated in the caulking portion.

상기와 같은 목적을 달성하기 위하여 본 발명은 외측 섀시부와 내측 섀시부로 이루어져 인쇄회로기판을 지지·고정하는 튜너의 섀시에 있어서, 상기 외측 섀시부의 내측에 돌출 성형하여 인쇄회로기판을 견고하게 끼움 고정할 수 있도록 한 엠보싱을 구비하는 것을 그 기술적 구성상의 기본 특징으로 한다.In order to achieve the above object, the present invention is a tuner chassis consisting of an outer chassis and an inner chassis to support and fix a printed circuit board, and protrudes and molds the printed circuit board to the inside of the outer chassis. It is a basic feature in the technical configuration that the embossing is made possible.
위와 같이 구성된 본 발명의 바람직한 실시예를 도면을 참조하면서 상세히 설명하면 다음과 같다.Referring to the preferred embodiment of the present invention configured as described above in detail with reference to the drawings as follows.
도 2는 본 발명에 따른 튜너의 섀시를 나타내는 인쇄회로기판을 포함한 사시도이고, 종래 구성과 동일 작용을 하는 동일 구성에 대해서는 동일 명칭 및 동일 부호를 병기 사용하기로 한다.2 is a perspective view showing a printed circuit board showing a chassis of a tuner according to the present invention, and the same name and the same reference numeral will be used for the same configuration having the same function as the conventional configuration.
도 2 에 나타낸 바와 같이, 본 발명의 튜너의 섀시는 인쇄회로기판의 면적에 대응하는 크기로 형성된 외측 섀시부(20)와, 상기 외측 섀시부(20)의 내부에 구비되어 인쇄회로기판의 하면을 지지하며 상기 인쇄회로기판에 성형된 고정구멍에 끼워지는 고정핀(31)이 형성된 내측 섀시부(30)로 이루어진다.As shown in FIG. 2, the chassis of the tuner according to the present invention includes an outer chassis 20 formed in a size corresponding to the area of the printed circuit board, and a lower surface of the printed circuit board in the outer chassis 20. It consists of an inner chassis portion 30 is formed with a fixing pin 31 is inserted into the fixing hole formed in the printed circuit board.
이때, 상기 외측 섀시부(20)의 내측에는 인쇄회로기판의 효율적인 삽입을 돕고, 후 공정의 인쇄회로기판 반전시 인쇄회로기판이 섀시에서 이탈되지 않도록 한 엠보싱(100)이 형성된다.In this case, an embossing 100 is formed inside the outer chassis 20 to assist the efficient insertion of the printed circuit board and prevent the printed circuit board from being separated from the chassis when the printed circuit board is inverted in a later process.
상기 구성으로 이루어진 종래 기술에 따른 튜너의 섀시의 결합동작 및 작용을 설명하면 다음과 같다.Referring to the coupling operation and action of the chassis of the tuner according to the prior art made of the above configuration as follows.
먼저, 섀시(10) 위에 결합시키고자 하는 인쇄회로기판을 위치시킨 후, 내측 섀시부(30)에 돌출 성형된 고정핀(31)이 인쇄회로기판의 고정구멍에 끼워질 수 있도록 인쇄회로기판을 상기 섀시(10)의 내측 섀시부(30) 위에 안착시킨다.First, after placing the printed circuit board to be bonded on the chassis 10, the printed circuit board is mounted so that the fixing pin 31 protrudingly formed in the inner chassis portion 30 can be fitted into the fixing hole of the printed circuit board. It rests on the inner chassis portion 30 of the chassis 10.
그리고, 상기 인쇄회로기판을 외측 섀시부(20)의 내측에 형성된 엠보싱(100)에 누름 가압하여 섀시(10)에 고정되도록 함으로써 결합을 완료하게 된다.Then, the printed circuit board is pressed to the embossing 100 formed inside the outer chassis 20 to be fixed to the chassis 10, thereby completing the coupling.
이때, 상기 엠보싱(100)은 인쇄회로기판의 상면과 밀착되어 섀시(10)와의 견고한 고정을 가능하게 하며, 후 공정을 위한 인쇄회로기판의 반전시 인쇄회로기판이 섀시(10)에서 이탈되는 것을 방지하게 된다.At this time, the embossing 100 is in close contact with the upper surface of the printed circuit board to enable a firm fixing with the chassis 10, the printed circuit board is released from the chassis 10 during the reversal of the printed circuit board for the subsequent process. Will be prevented.
이상에서 살펴본 바와 같이 본 발명에 따른 튜너의 섀시에 의하면, 외측 섀시부에 형성된 코킹편을 제거하고 내측에 엠보싱을 형성하여 코킹기 없이 인쇄회로기판을 섀시에 견고하게 고정되도록 함으로써 작업공정의 단축 및 설비의 절감에 따라 작업의 생산성이 향상되고, 납땜작업 없이 인쇄회로기판을 섀시에 고정되도록 함으로써 리플로우 작업 후에도 냉땜이 발생되지 않는 효과가 있다.As described above, according to the chassis of the tuner according to the present invention, by eliminating the caulking piece formed in the outer chassis portion and forming an embossing on the inner side to shorten the work process by firmly fixing the printed circuit board to the chassis without caulking and As the equipment is reduced, the productivity of the work is improved, and the printed circuit board is fixed to the chassis without soldering, so that cold soldering does not occur even after reflowing.
