본 고안은 변, 복조 장치의 케이스와 결합구조에 관한 것으로서, 특히 나사와 같은 별도의 체결부재를 사용치 않고 자체 탄성력을 탄성록킹편으로 간단하며서도 견고하게 결합토록 하여 조립과 분해 또한 용이토록 한 것이다.The present invention relates to a case and a coupling structure of a side and a demodulation device. In particular, it is easy to assemble and disassemble by easily and firmly combining its elastic force with an elastic locking piece without using a separate fastening member such as a screw. will be.
종래에는 인쇄회로기판을 내설한 케이스(10′) 후방에 커버(30′)를 결합시키기 브라켓트를 이용하여 케이스 측면 및 후면을 위하여 나사부재로서 체결하면서, 커버(30′)에 돌출된 결합구(31′)로서 케이스 저면에 형성된 록킹홈(11′)에 삽입시켜 내측에 인쇄회로기판(20′)이 설치된 케이스와 커버를 결합하였다.Conventionally, the coupling 30 protruding from the cover 30 'while being fastened as a screw member for the side and the back of the case by using a bracket for coupling the cover 30' to the rear of the case 10 'having the printed circuit board ( 31 ') was inserted into the locking groove 11' formed at the bottom of the case, and the case and the cover having the printed circuit board 20 'installed therein were combined.
그러나 이는 케이스의 후면과 측면을 나사부재로 고정시키면서 커버에 돌출한 결합구로서 다시 한번 더 고정 시켜야 하는 필요이상의 작업공정이 필요하므로해서 조립과 해체시의 번거로움이 뒤따랐고, 분해 및 조립시에는 록킹홈과 결합될 록킹홈에 고정시키기 위한 결합구의 신장된 커버 부위의 파손이 빈번하여 조립시 인쇄회로 기판에 부착된 부품의 손상을 초래하였다.However, this is a coupler that protrudes to the cover while fixing the back and side of the case with a screw member, which requires more work than needed to fix it once more, which is cumbersome when assembling and disassembling. Breakage of the elongated cover portion of the coupler for fastening to the locking groove to be combined with the locking groove frequently caused damage to the components attached to the printed circuit board during assembly.
뿐만 아니라, 조립완료후 케이스와 커버 사이의 유동이 발생하여 제품의 신뢰도를 실추시키는 등 사용상의 문제점을 지니고 있었다.In addition, there was a problem in use, such as flow between the case and the cover after assembly is completed, which degrades the reliability of the product.
따라서, 본 고안은 상기와 같은 종래의 문제점을 해결하면서 제품의 신뢰도를 상승시키기 위하여 각 연결 부위를 별도의 체결부재를 사용치 않고 탄성력을 가지는 탄성체결편으로서 변, 복조 장치의 케이스와 커버를 결합시키기 위한 것이다.Therefore, the present invention combines the case and the cover of the demodulation device as an elastic fastening piece having elastic force, without using a separate fastening member for each connection portion to increase the reliability of the product while solving the conventional problems as described above. It is to let.
이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.
콘넥터(21)가 부착된 인쇄회로기판(20)을 양측내측면에 가이드홈(11)을 형성한 케이스(10) 내측으로 삽입설치하고, 그 후방을 콘넥터 노출구(31)를 구비한 커버(30)로서 고정 설치함에 있어서, 상기 케이스(10)의 저면 후방에 걸림홈(12)를 형성하고, 케이스(10) 내측에 삽입 설치된 인쇄 회로기판(20)의 콘넥터(21)상부에는 고정편(22)이 형성되었고, 커버(30)의 상부 콘넥터 노출구(31) 상측에는 상기 고정편(22)에 결합될 삽입 안내용 경사면(33)을 구비한 록킹편(32)이 형성되고 하측에는 스피커 구멍(36)이 천공되면서 케이스의 걸리홈(12)과 록킹될 록킹부(35)를 구비한 결합구(34)가 형성된 것이다.The printed circuit board 20 with the connector 21 is inserted into the case 10 having the guide grooves 11 formed on both inner side surfaces thereof, and a cover having the connector exposure opening 31 at the rear thereof. In the fixed installation 30, the locking groove 12 is formed on the rear of the bottom of the case 10, and the fixing piece is formed on the upper portion of the connector 21 of the printed circuit board 20 inserted into the case 10. 22 is formed, a locking piece 32 having an insertion guide inclined surface 33 to be coupled to the fixing piece 22 is formed above the upper connector exposure opening 31 of the cover 30 and a speaker below. As the hole 36 is drilled, a coupling hole 34 having a locking groove 12 of the case and a locking portion 35 to be locked is formed.
이상과 같이 구성된 본 고안의 작용상태를 설명하면 다음과 같다.Referring to the working state of the present invention configured as described above are as follows.
콘넥터(21)가 부설된 인쇄회로기판(20)을 케이스(10) 내측 양측에 형성된 가이드홈(11)내로 삽입하고, 커버(30)를 삽입시키면서 콘넥터 노출구(31) 하측에 형성된 결합구(34)의 자체 탄성력에 의해 케이스(10) 저면에 형성된 걸림홈(12) 내로 결합구의 록킹부(35)가 삽입되어 결합이 이루어지게 됨과 동시, 상기 콘넥터 노출구(31) 상측에 형성된 록킹편(32)이 인쇄회로기판(20) 말단부에 설치된 콘넥터 상부에 횡단 설치된 고정편(22)에 걸리게 되어 커버의 콘넥터 노출구(31)로 인쇄회로기판(20) 말단부에 설치된 콘넥터(21) 후미가 돌출되도록 고정되는 것이며, 이를 보수 및 점검을 목적으로 분해시에는 커버(30)의 콘넥터 노출구(31)로 후미 돌출된 콘넥터를 도면 제2의 “A”와 같이 하방으로 누루게 되면 록킹편(32)에 걸려 있던 고정편(22)이 이탈하고 되고, 케이스(10) 저면 걸림홈(12)에 걸려 록킹된 결합구의 록킹부(35)를 “B”와 같이 상부로 밀어 올리게 되면 케이스 저면 걸림홈(12)에 걸려있던 록킹부(35)가 이탈하게 되어 록킹이 해제된 상태에서 커버(30)를 후방으로 빼낸뒤, 커버의 내측 양측의 가이드홈(11)내에 위치한 인쇄회로기판(20)을 후방으로 빼내게 되면 인쇄회로기판은 커버의 가이드홈(11)내에서 슬라이딩 안내 되면서 분해가 완료되는 것이다.Inserting the printed circuit board 20 in which the connector 21 is installed into the guide grooves 11 formed on both sides of the case 10 and inserting the cover 30, the coupling hole formed on the lower side of the connector exposed port 31 ( The locking piece 35 of the coupling hole is inserted into the locking groove 12 formed on the bottom surface of the case 10 by the self-elastic force of 34, and the locking piece 35 formed on the connector exposure opening 31 is formed at the same time. 32 is caught by the fixing piece 22 which is transversely installed on the upper part of the connector installed at the end of the printed circuit board 20, and the rear end of the connector 21 provided at the end of the printed circuit board 20 protrudes through the connector exposure opening 31 of the cover. When disassembling for the purpose of maintenance and inspection, if the connector protrudes downward from the connector exposing port 31 of the cover 30 downward as shown in "A" of the drawing 2, the locking piece 32 Fixed piece 22 hanging on the When the locking portion 35 of the coupler that is locked by the surface locking groove 12 is pushed upward, as shown by the letter “B”, the locking portion 35 held by the bottom locking groove 12 of the case is separated and the locking is released. After the cover 30 is pulled out in the back state, and the printed circuit board 20 located in the guide grooves 11 on both inner sides of the cover is pulled out, the printed circuit board is removed from the guide groove 11 of the cover. The disassembly is completed by sliding guide.
이상과 같이 구성되고 작용하는 본 고안은, 커버의 상측에 형성된 록킹편으로 케이스내에 삽입된 인쇄 회로 기판을 고정시키면서, 하측의 결합구로는 케이스를 고정하게 되므로 한동작으로 동시에 케이스와 인쇄회로 기판을 견고하게 고정시킬 수 있고 별도의 체결 부재가 필요없이 자체 탄성력을 가진 각각의 록킹편과 결합구로서 결합구조를 형성하여 생산원가를 절감시킬뿐만 아니라 분해 조립이 용이하면서 작업시간을 단축시키므로서 작업능률을 향상시키는 매우 유용한 고안이다.The present invention is constructed and functioned as described above, while fixing the printed circuit board inserted into the case by the locking piece formed on the upper side of the cover, and fixing the case with the lower coupling holes at the same time, the case and the printed circuit board It can be fixed firmly and forms a joining structure as each locking piece and coupling device with its own elastic force without the need for a separate fastening member, which not only reduces the production cost but also facilitates disassembly and assembly, and shortens working time. It is a very useful design to improve it.
