도 2 및 도 3에 도시한 바와 같이 본 고안에 적용되는 입출력 플러그는 플라스틱 등의 재질로 된 하우징(도시생략)으로 구성되되, 그 내부에 핸드폰 또는 PDA의 입출력 단자에 결합하여 핸드폰의 전원공급용 커넥터로 이용하거나, 또는 외부장치와 연결되어 PDA의 데이터를 외부로 전송하거나 PDA의 데이터를 외부로부터 수신할 수 있도록 일측에 접촉핀(11)(12)을 구비한 상태로 돌출 형성된 도킹부(10)와, 내부에 외부전원과 연결되는 연결 케이블(도시생략)을 구비한 상태로 상기 도킹부(10)의 접촉핀(11)(12)과 결합되어 상호 조립되는 인쇄회로기판(20)이 포함된다.As shown in Figure 2 and 3, the input and output plugs applied to the present invention is composed of a housing (not shown) made of a material such as plastic, it is coupled to the input and output terminals of the mobile phone or PDA therein for power supply of the mobile phone Docking portion 10 protruded with a contact pin 11, 12 on one side to be used as a connector, or connected to an external device to transmit the data of the PDA to the outside or to receive the data of the PDA from the outside. ) And a printed circuit board 20 coupled with the contact pins 11 and 12 of the docking unit 10 while having a connection cable (not shown) connected to an external power source therein. do.
상기 도킹부(10)의 접촉핀(11)(12)은 핸드폰과의 결합부위 반대편 쪽으로 좌측부터 순서대로 상하 교차한 형태로 소정 길이 돌출 형성되고, 케이블의 일측은 상기 접촉핀(11)(12)에 부합되도록 구성되어 인쇄회로기판(20)에 설치된다.The contact pins 11 and 12 of the docking part 10 are formed to protrude a predetermined length in the form of vertically crossing from the left side to the opposite side of the coupling part with the mobile phone, and one side of the cable is the contact pins 11 and 12. It is configured to conform to the installed on the printed circuit board 20.
즉, 상기 접촉핀(11)(12) 사이에 인쇄회로기판(20)을 삽입하면 인쇄회로기판(20) 상하부에 상부핀(11)과 하부핀(12)이 위치하여 서로 지그재그식 교차 형태로 압입 결합되어 적절한 텐션을 갖는 텐션부(22)를 형성하고, 상기 텐션부(22)의 텐션력에 의해 인쇄회로기판(20)이 도킹부(10)에 고정 결합되는 것이다.That is, when the printed circuit board 20 is inserted between the contact pins 11 and 12, the upper pin 11 and the lower pin 12 are positioned above and below the printed circuit board 20 so that they cross each other in a zigzag cross shape. It is press-fitted to form a tension part 22 having an appropriate tension, and the printed circuit board 20 is fixedly coupled to the docking part 10 by the tension force of the tension part 22.
이때, 상기 텐션부(22)중 인쇄회로기판(20)의 최상단 위치에는 상부핀(11)과 하부핀(12)의 결합상태를 고정하도록 납땜을 이용한 납땜부(21)가 형성되고, 상기 납땜부(21)는 텐션부(22)에 강한 조임이나 헐거움이 발생되지 않도록 텐션부(22)의 시작위치로부터 최대한 인쇄회로기판(20)의 케이블 고정부(도시생략) 쪽으로 이격된 위치에 형성되며, 텐션부(22)의 시작위치와 납땜부(21) 사이에는 디핑시 납의 흐름이 정지되도록 소정 높이를 갖는 도피부(24)가 형성됨과 동시에, 이격에 의한 상부핀(11)과 하부핀(24)의 쇼트를 방지할 수 있도록 소정 길이의 이격부(25)가 자연스레 형성된다. 상기 텐션부(22)의 길이는 납땜부(21)의 도피부(24) 및 이격부(25)의 형성을 위해 기존의 텐션부(22)에 비해 최소 1.5배 정도 되도록 길게 형성하는 것이 바람직하다.In this case, a soldering unit 21 using soldering is formed at the uppermost position of the printed circuit board 20 of the tension unit 22 to fix the coupling state of the upper pin 11 and the lower pin 12. The part 21 is formed at a position separated from the start position of the tension part 22 toward the cable fixing part (not shown) of the printed circuit board 20 as much as possible so that no strong tightening or loosening occurs in the tension part 22. In addition, between the start position of the tension portion 22 and the soldering portion 21 is formed with an escape portion 24 having a predetermined height to stop the flow of lead when dipping, at the same time the upper pin 11 and the lower pin ( A spacing 25 of a predetermined length is naturally formed so as to prevent the short of 24. The length of the tension portion 22 is preferably formed to be at least 1.5 times longer than the existing tension portion 22 to form the escape portion 24 and the spacer portion 25 of the soldering portion 21. .
한편, 상기 접촉핀(11)(12)은 도 3에 도시한 바와 같이, 조립 후 외관검사시육안만으로 조립상태(역삽 또는 오삽인지의 여부)를 쉽게 확인할 수 있도록 상부핀(12)이 하부핀(11)에 비해 소정 길이 짧게 형성해도 된다.On the other hand, the contact pins (11, 12), as shown in Figure 3, the upper pin 12 is a lower pin so that the assembly state (whether it is a reverse or wrong shovel) can be easily confirmed only with the naked eye during the appearance inspection after assembly. You may form a predetermined length short compared with (11).
이와 같이 구성된 핸드폰용 입출력 플러그의 제작공정은 다음과 같다.The manufacturing process of the input / output plug for a mobile phone configured as described above is as follows.
일측에 핸드폰의 입출력 단자에 연결되는 접촉핀(11)(12)이 구비된 도킹부(10)에 케이블이 구비된 인쇄회로기판(20)을 삽입하여 인쇄회로기판(20)의 상측에는 상부핀(11), 하측에는 하부핀(12)이 밀착되도록 도킹부(10)와 인쇄히로기판(20)을 결합한다. 이때, 상기 접촉핀(11)(12)과 인쇄회로기판(20)은 서로 나란히 일렬로 정렬된 상태가 되고, 인쇄회로기판(20)은 적절한 텐션력에 의해 고정되는 것이다.Inserting the printed circuit board 20 provided with a cable into the docking unit 10 having the contact pins 11 and 12 connected to the input and output terminals of the mobile phone on one side, the upper pin on the upper side of the printed circuit board 20 (11), the lower side is coupled to the docking portion 10 and the printing hero substrate 20 so that the lower pin 12 is in close contact. In this case, the contact pins 11 and 12 and the printed circuit board 20 are aligned in parallel with each other, and the printed circuit board 20 is fixed by an appropriate tension force.
이후, 상기 텐션부(22)의 최상단부에 납땜에 의해 납땜부(21)를 형성하여 접촉핀(11)(12)과 인쇄회로기판(20)이 서로 단리되는 것을 방지한다. 이때, 텐션부(22)의 시작위치로부터 납땜부(21) 사이의 텐션부는 소정 길이의 이격부(25)가 되며, 상기 이격부(25) 위치의 접촉핀(11)(12)은 소정 높이 상하로 각각 이격되어 자연스레 소정 높이의 도피부(24)를 형성하게 된다.Thereafter, a soldering portion 21 is formed at the uppermost end of the tension portion 22 by soldering to prevent the contact pins 11 and 12 and the printed circuit board 20 from being isolated from each other. At this time, the tension portion between the soldering portion 21 from the start position of the tension portion 22 becomes a spaced portion 25 of a predetermined length, and the contact pins 11 and 12 at the spaced portion 25 position have a predetermined height. They are spaced apart from each other up and down to naturally form an escape portion 24 of a predetermined height.
상술한 본 고안은 특정한 실시예를 들어 설명하였으나 본 고안은 이에 한정하는 것은 아니며 본 고안의 기술적 사상의 범주 내에서는 수정 및 변형 실시가 가능하다.The present invention described above has been described with reference to specific embodiments, but the present invention is not limited thereto, and modifications and variations can be made within the scope of the technical idea of the present invention.
즉, 텐션부 및 도피부의 길이는 제품에 알맞게 적절한 텐션의 유지를 위해 조정하여 제작할 수 있다.That is, the length of the tension portion and the escape portion can be produced by adjusting the appropriate tension to maintain the product.
이상에서 설명한 바와 같이, 본 고안의 입출력 플러그의 핀 구조에 따르면, 인쇄회로기판 상의 납땜부분을 텐션부의 시작위치로부터 최대한 이격시킴으로써 삽입시 강한 조임에 의한 제품불량률을 최소화함은 물론 헐거움에 의한 전면 핀의 정렬불량을 억제할 수 있고, 이에 따라 텐션부에는 소정 길이의 도피부 및 이격부가 자연스레 형성됨으로 디핑시 중간 부분에서 납의 흐름을 정지시켜 핀과 핀의 쇼트를 방지할 수 있는 효과를 얻을 수 있다.As described above, according to the pin structure of the input / output plug of the present invention, the soldering part on the printed circuit board is spaced apart from the start position of the tension part as much as possible to minimize the defective rate of the product due to the strong tightening during insertion, as well as the front pin due to looseness. The misalignment can be suppressed, and accordingly, the tension portion and the spaced portion are naturally formed in the tension portion, thereby stopping the flow of lead in the middle part during dipping, thereby obtaining an effect of preventing the short between the pin and the pin. have.
