종래 바톰 샤시에 장설된 인쇄회로기판을 수리하고자 할 때에는 일일이 나사를 풀어 인쇄회로기판을 바톰 샤시로 부터 분해하고 이를 뒤집어서 수리하여야 하였으므로, 수리시 그 분해 작업이 매우 번거롭고 불편하며 이로 인하여 그 시간이 많이 소요되는 등의 폐단이 따랐던 것이다.In order to repair a printed circuit board installed in a conventional bottom chassis, it was necessary to disassemble the printed circuit board from the bottom chassis and repair it by unscrewing one by one. Therefore, the disassembly work is very cumbersome and inconvenient during repair. This was followed by the discontinuance.

따라서 본 고안은 상기한 바와 같은 종래 폐단을 해결코저 안출된 것으로서 특히 바톰 샤시에 일정한 형상의 인쇄회로기판 수리부를 천공하고, 천공된 판은 일단부를 절곡시켜 이를 방향을 바꿔 다시 바톰 샤시에 체결 고정하므로서 인쇄회로기판 수리시 천공된 판만을 분해하여 인쇄회로기판이 고정된 상태에서 바로 수리 등을 할 수 있도록 한 개량 바톰 샤시를 제공하는데 그 목적이 있는 것으로 이하 첨부된 도면에 의거 상세히 설명하면 다음과 같다.Therefore, the present invention is designed to solve the conventional closed end as described above, and in particular, perforated printed circuit board repair portion of a certain shape in the bottom chassis, and the perforated plate is bent at one end by changing the direction to be fixed back to the bottom chassis The purpose of the present invention is to provide an improved bottom chassis for disassembling only a perforated plate when repairing a printed circuit board, thereby allowing the printed circuit board to be repaired in a fixed state. .

바톰 샤시(1)의 일측에 나사 체결홈(2)을 가진형 체결부(3)(3a) 및 타측에 상기 체결부(3)(3a)보다 외곽으로형 익편(4)(4a)를 형성하여서 된 보조판(5)이 천공되게 하되, 보조판(5)이 천공된 다음에 형성되는 체결부 자리(3′)(3′a) 외측으로 재치요홈(6)을 형성시키고, 상기 익편자리(4′)(4′a) 내측에는 상기 체결부(3)(3a)의 나사 체결홈(2)이 일치되는 부분에 나공(7)을 천공하여, 보조판(5)은 일측에 형성된형 익편(4) 및 (4a)를형으로 시켜 절곡편(8)으로 형성시킨 다음, 이 보조판(5)의 방향을 바꿔서 즉 절곡편(8)이 재치요홈(5)으로형 체결부(3) 및 (3a)가 나공(7)으로 위치되게 한 후 상기 체결부(3) 및 (3a)를 통하여 나공(7)에 나사(9)를 체결하여 고정토록 된 음향기기용 개량 바톰 샤시인 것이다.With screw fastening groove (2) on one side of bottom chassis (1) On the other side of the type fastening portion (3) (3a) and outward from the fastening portion (3) (3a) The auxiliary plate 5 formed by forming the die blades 4 and 4a is perforated, but the recess 6 is formed outside the fastening portion 3'3'a formed after the auxiliary plate 5 is perforated. ) And perforations (7) in the portion where the screw fastening groove (2) of the fastening portion (3) (3a) coincides inside the wings 4 '(4'a), the auxiliary plate ( 5) formed on one side Mold blades (4) and (4a) To form a bent piece (8), and then change the direction of the auxiliary plate (5), that is, the bent piece (8) to the mounting groove (5) Improved for sound equipment fixed by fixing the screw (9) to the hole (7) through the fastening portion (3) and (3a) after the type fastening portion (3) and (3a) is located in the hole (7) It's a bottom chassis.

미 설명 부호 11은 천공부, 12는 인쇄회로기판, 13은 나사이다.Reference numeral 11 is a perforation part, 12 is a printed circuit board, and 13 is a screw.

위와 같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

먼저 바톰샤시(1)를 음향기기 본체에 장설하기 전에 보조판(5)을 프레스 등으로서 천공시키고, 이어서 바톰 샤시(1) 일측에 재치요홈(6)을 형성시킨 다음 바톰샤시(1)의 천공부(11)로 부터 인출되는 보조판(5)의 일측형 익편(4)(4a)를 절곡시켜형의 절곡편(8)을 형성시킨 후, 상기 바톰샤시(1)의 익편자리(4′)(4′a) 내측에 체결부(3)(3a)의 나사 체결홈(2)과 일치되도록 나공(7)을 천공하며, 이 상태에서 보조판(5)의형 체결부(3)(3a)가 바톰샤시(1)의 나공(7)에 위치되도록 하여 나사(9)로서 체결 고정하고, 절곡편(8)은 바톰샤시(1)의 재치요홈(6)에 재치되게 한 다음 인쇄회로기판(12)을 나사(13)로서 고정시키는 것으로 이 상태에서 인쇄회로기판(12)을 수리하여야 할 경우에는 인쇄회로기판(12)이 조립되어 있는 상태에서 보조판(5)의 체결부(3)(3a)에 체결된 나사(9)만을 풀어 보조판(5)을 바톰샤시(1)로 부터 분리한 다음 바톰샤시(1)의 저면에서 천공부(11)를 통하여 인쇄회로기판(12)을 수리하면 되는 것이다.First, before the bottom chassis 1 is installed in the main body of the acoustic apparatus, the auxiliary plate 5 is punched by a press or the like, and then, a recess groove 6 is formed on one side of the bottom chassis 1, and then the perforated portion of the bottom chassis 1 is formed. One side of the auxiliary plate 5 withdrawn from (11) By bending the mold blade (4) (4a) After forming the bent piece (8) of the die, so as to coincide with the screw fastening groove (2) of the fastening portion (3) (3a) inside the flap 4 '(4'a) of the bottom chassis (1). Perforations (7), in this state of the auxiliary plate (5) The fastener (3) (3a) is positioned in the hole (7) of the bottom chassis (1) to be fastened and fixed as a screw (9), the bending piece (8) is a mounting groove (6) of the bottom chassis (1) The printed circuit board 12 is fixed by the screws 13 and the printed circuit board 12 is repaired in this state. Loosen only the screw (9) fastened to the fastening portion (3) (3a) of the) and separate the auxiliary plate (5) from the bottom chassis (1) and then print through the perforations (11) at the bottom of the bottom chassis (1) The circuit board 12 may be repaired.

상술한 바와 같이 본 고안은 인쇄회로기판(12) 수리시 바톰샤시(1)로 부터 인쇄회로기판(12)을 분해하지 않고 수리할 수 있으므로서 인쇄회로기판(12) 분해시 야기되는 부품의 파손과 망실 등을 미연에 방지할 수 있고 수리를 극히 간편하게 할 수 있는 등의 효과가 있는 것으로 특히 보조판(5)은 바톰 샤시(1)를 그대로 이용하는 것이므로 재료비 등이 절감되면서 제작이 극히 간편한 잇점이 있는 유용한 고안인 것이다.As described above, the present invention can repair the printed circuit board 12 without disassembling the printed circuit board 12 from the bottom chassis 1 when the printed circuit board 12 is repaired. It is possible to prevent the loss and loss in advance and to make the repair extremely simple. In particular, the auxiliary plate 5 uses the bottom chassis 1 as it is, so the material cost is reduced and the production is extremely easy. It is a useful design.
