본 고안은 오디오나 비디오 및 카세트, 라디오와 같은 각종 전자제품과 이어폰 및 헤드폰 마이크, 스피커등을 전기적으로 연결시켜 주기 위한 플러그에 관한 것으로 특히 플러그와 코드선의 접속을 용이하게 하고, 공정단축과 단락방지를 통하여 생산성 향상과 제품의 신뢰성을 높일 수 있도록 한 전자제품용 코드플러그에 관한 것 이다.The present invention relates to a plug for electrically connecting various electronic products such as audio, video, cassette, radio, earphone, headphone microphone, speaker, etc., and in particular, facilitates the connection of the plug and the cord, and prevents shortening of the process and short circuit. It is about the code plug for electronic products that can improve productivity and increase the reliability of the product.
일반적으로 오디오나 비디오 및 카세트, 라디오과 같은 각종전자제품과 이어폰 및 헤드폰, 마이크, 스피커등을 전기적으로 연결할때는 상기한 전자제품에 잭공(Jack Holc)을 형성하고, 여기에 이어폰 및 헤드폰 마이크, 스피커등의 코드선과 접속된 플러그를 결합함으로서 각각의 전자제품에서 발생된 음성신호가 잭공과 플러그 및 코드선을 통하여 이어폰과 헤드폰, 마이크, 스피커에 전달하게 된다.In general, when the electronics such as audio, video, cassette, radio, and earphones, headphones, microphones, speakers, etc. are electrically connected to each other, a jack hole is formed in the above electronic products, and earphones, headphones, microphones, speakers, etc. By combining the cord and the plug connected, the voice signal generated from each electronic product is transmitted to the earphone, headphone, microphone and speaker through the jack hole, the plug and the cord.
이러한 플러그를 형성함에 있어 종래에는 제1도 및 제2도에서 보는 바와 같이 잭공에 강제 압입되는 플러그(7')의 팁(1')후단에 길이가 길며 원형으로 된 접속핀(2')을 삽입하여 고정시킨 다음 이 접속핀(2') 둘레에 절연체인 합성수지(3)와 오른쪽단자인 금속링(4') 및 다시 절연체인 합성수지(5'), 어스단자인 금속링(6')을 차례로 형성하여 왼쪽단자인 팁(2')파 접속핀(2') 및 각각의 금속링(4')(6')을 합성수지(3')(5')를 통하여 절연시키고, 이중 외측의 합성수지(5')후단부 일측에 개구부(5'a)를 형성하여 그 내부의 금속링(4')이 외부로 노출되게 하며, 외측의 금속링(6') 주연에는 돌기(6')를 형성함으로서 이어폰 및 헤드폰 마이크, 스피커등과 연결된 코드선(11')을 상기 외부로 돌출된 접속편(2')후단과 개구부(5'a)내의 금속링(4')및 외측금속링(6')의 돌기(6'a) 후단부에 각각 납땜(Soldering)으로 접속, 고정시켜 플러그(7')선단부를 전자제품의 젝공에 강제로 압입시키면, 이들 전자제품과 이어폰 및 헤드폰, 마이크, 스피커가 전기적으로 도통하여 음성신호를 전달하였던 것이다.In forming such a plug, as shown in FIGS. 1 and 2, a long, circular connecting pin 2 'is formed at the rear end of the tip 1' of the plug 7 'which is forcibly pressed into the jack hole. Insert and fix it. Then, around this connecting pin (2 '), put a synthetic resin (3), an insulator, a metal ring (4') on the right side, a synthetic resin (5 '), and an earth terminal (6'). Formed in turn, the left terminal (2 ') wave connecting pin (2') and each metal ring (4 ', 6') is insulated through synthetic resin (3 ', 5'), double outer synthetic resin (5 ') Opening portion 5'a is formed at one end of the rear end to expose the inner metal ring 4' to the outside, and a protrusion 6 'is formed around the outer metal ring 6'. Cords 11 'connected to earphones, headphone microphones, speakers, etc., and the metal ring 4' and the outer metal ring 6 'in the rear end of the connecting piece 2' and the opening 5'a. At the rear end of the projection (6'a) When the plug 7 'tip was forcibly pressed into the hole of the electronic product by connecting and fixing them by soldering, respectively, these electronic products, earphones, headphones, microphones, and speakers were electrically connected to each other to transmit voice signals.
이때 플러그(7')와 코드선(11')을 연결할때는 제3도와 같이 코드선(11')내의 각각의 리드선(8')(9')(10')선단부 피복을 벗겨낸 다음, 피복이 벗겨진 스트립(strip)부위를 접속핀(2') 후단과 개구부(5')내의 금속링(4'), 외측금속링(6')의 돌기(6') 후단부에 밀착시키고 여기에 인두(15)로 땜납(16)을 용융시켜 접속하였던 것이다.At this time, when connecting the plug 7 'and the cord wire 11', the coating of the ends of the respective lead wires 8 ', 9', 10 'in the cord wire 11' is peeled off as shown in FIG. The stripped strip is brought into close contact with the rear end of the connecting pin 2 ', the metal ring 4' in the opening 5 'and the rear end of the projection 6' of the outer metal ring 6 ', The solder 16 was melted and connected by (15).
따라서 이와같이 플러그(7')와 코드선(11')을 연결하면, 먼저 플러그(7')를 고정시켜 유동이 방지되게 한다음, 코드선(11')을 구성하고 있는 각각의 리드선(8')(9')(10')의 선단부피복을 벗겨 이를 접속핀(2')과 금속링(4') (6')에 밀착시키고, 여기에 납땜으로 고정시켜야 함으로서 둘이상의 작업인원이 필요하여 인건비 상승과 생산성저하 및 원가상승을 초래하였던 것이다.Therefore, when the plug 7 'and the cord wire 11' are connected in this way, the plug 7 'is first fixed to prevent the flow, and then the respective lead wires 8' constituting the cord wire 11 '. Peel off the cover of the tip of 9 'and 10' and attach it to the connecting pin 2 'and the metal ring 4' and 6 ', and fix it with solder. This has led to higher labor costs, lower productivity, and higher costs.
또한 플러그(7')의 접속핀(2')은 통상 그 직경이 1mm내, 외인데 여기에 납땜을 하게 되면, 상호접착면적이 작고, 납땜 위치가 부정확하며, 접속이 제대로 이루어지지 않아 사용중 조그만 외력이 작용하더라도 접속부위에서 단락되는 사례가 번번히 발생하였던 것이다.In addition, the connecting pin 2 'of the plug 7' is usually less than 1 mm in diameter, but when soldering to it, the interconnection area is small, the soldering position is incorrect, and the connection is not made properly. Even if an external force is applied, a case of short-circuit occurs frequently.
본 고안은 이러한 제반문제점을 해졀하기 위하여 외측합성수지의 후단부 양측에 개구부를 형성하여 코드선의 피복을 벗기지 않고도 직접 스포트 용접(spot welding)으로 접속 가능하게 하고, 후단으로 돌출된 접속핀을 단조가동등을 통하여 반원형이나 사각형 및 요홈형상으로 형성함으로서 코드선과 접속면적을 넓혀 접속이 용이하도록 안출한 것이다.In order to solve these problems, the present invention forms openings on both sides of the rear end of the outer synthetic resin to enable direct spot welding without removing the coating of the cord wires, and the connecting pin protruding to the rear end is forged, etc. By forming a semi-circle, a square, and a groove through the shape of the wire and the connection area is widened to facilitate the connection.
