Description

이동통신단말기용 플러그 커넥터{PLUG CONNECTOR FOR A MOBILE COMMUNICATION DEVICE}PLUG CONNECTOR FOR A MOBILE COMMUNICATION DEVICE}

본 발명은 이동통신단말기용 전기커넥터에 관한 것으로, 특히 이동통신단말기용 플러그 커넥터에 관한 것이다.The present invention relates to an electrical connector for a mobile communication terminal, and more particularly to a plug connector for a mobile communication terminal.

일반적으로, 전기커넥터는 복수개의 전자기기를 전기적으로 연결하는 데에 사용된다. 특히, 이동통신단말기에 데이터 케이블이나 전원케이블 및 이어폰을 연결하기 위한 커넥터는 이동통신단말기에 구비되는 소켓 커넥터와, 케이블에 구비되어 소켓에 탈착가능하게 끼워지는 플러그 커넥터로 구성된다. In general, electrical connectors are used to electrically connect a plurality of electronic devices. In particular, the connector for connecting the data cable, power cable and earphone to the mobile communication terminal is composed of a socket connector provided in the mobile communication terminal, and a plug connector provided in the cable detachably inserted into the socket.

종래 플러그 커넥터는 등록실용신안 제418058호(공고일.2006.06.09) 「접속력을 향상시킨 핀이 구성된 핀홀더」에 개시된 바와 같이, 접속핀은 인쇄회로기판의 단자에 전기적으로 접속될 뿐만 아니라 인쇄회로기판의 외측면을 지지하기도 한다. 따라서, 접속핀의 갯수가 줄어들게 되면 지지력이 감소하는 문제점이 있었다. Conventional plug connectors are disclosed in Korean Utility Model Registration No. 418058 (published on 06.09.2006), `` Pinholders with Pins with Improved Connection Force, '' where the connecting pins are not only electrically connected to the terminals of the printed circuit board but also printed.

For example, if the number of connection pins is 20, 10 connection pins are divided and supported on the top and bottom surfaces of the printed circuit board to support the printed circuit board with only the connection pins. If the number of pins is reduced, the bearing capacity is greatly reduced.

또한, 종래의 플러그 커넥터가 이어폰 잭의 단자부로 사용될 경우 플러그 커넥터의 외부셸의 접지가 제대로 되지 않아 노이즈가 발생되는 문제점이 있었다. In addition, when the conventional plug connector is used as the terminal portion of the earphone jack, there is a problem that noise is generated because the outer shell of the plug connector is not properly grounded.

이하, 첨부된 도면을 참조하여 본 발명에 따른 이동통신단말기용 플러그 커넥터의 바람직한 실시예를 상세히 설명한다. Hereinafter, exemplary embodiments of a plug connector for a mobile communication terminal according to the present invention will be described in detail with reference to the accompanying drawings.

도 6과 도 7에 도시된 바와 같이, 본 발명에 따른 이동통신단말기용 플러그 커넥터는 이동통신단말기용 소켓 커넥터(100)에 탈착가능하게 끼워지는 부품으로, 통상 소켓 커넥터(100)는 이동통신단말기의 인쇄회로기판(PCB)에 결합되고, 플러그 커넥터는 이동통신단말기로 연결하고자 하는 기기의 인쇄회로기판(1)에 결합된다.6 and 7, the plug connector for a mobile communication terminal according to the present invention is a component that is detachably fitted to the socket connector 100 for a mobile communication terminal, and the socket connector 100 is a mobile communication terminal. It is coupled to the printed circuit board (PCB), the plug connector is coupled to the printed circuit board 1 of the device to be connected to the mobile communication terminal.

도 1 내지 도 7을 참조하면, 본 발명의 일실시예에 따른 이동통신단말기용 플러그 커넥터는, 서로 소정간격을 두고 구비되는 복수개의 접속핀(10), 상기 접속핀(10)을 지지하는 절연체(20), 및 상기 절연체(20)를 감싸는 외부셸(30)을 포함한다.1 to 7, a plug connector for a mobile communication terminal according to an embodiment of the present invention includes a plurality of connection pins 10 provided at predetermined intervals from each other, and an insulator supporting the connection pins 10. 20, and an outer shell 30 surrounding the insulator 20.

상기 접속핀(10)은 절연체(20)에 지지되는 핀몸체(11)와, 상기 핀몸체(11)의 선단에 연장된 아암부(12), 상기 아암부(12)의 선단에 잘록하게 형성된 손목부(13), 상기 손목부(13)의 선단에 연장된 접촉부(14), 및 상기 핀몸체(11)의 후단으로 연장된 후단절곡부(15)를 포함한다.The connecting pin 10 is formed to have a pin body 11 supported by the insulator 20, an arm part 12 extending at the tip of the pin body 11, and a tip of the arm part 12. Wrist portion 13, a contact portion 14 extending to the front end of the wrist portion 13, and a rear end bending portion 15 extending to the rear end of the pin body (11).

본 실시예에 따른 플러그 커넥터는 20개(10개×2)의 접속핀(10)이 인쇄회로기판(1)에 접속된다. In the plug connector according to the present embodiment, twenty (10 × 2) connecting pins 10 are connected to the printed circuit board 1.

상기 핀몸체(11)는 절연체(20)를 관통하여 결합된다. 상기 핀몸체(11)는 스토퍼(11a)를 돌출되게 구비하여 접속핀(10)이 인쇄회로기판(1) 쪽으로 밀리지 않도록 지지하게 된다. The pin body 11 is coupled through the insulator 20. The pin body 11 is provided with a stopper (11a) to protrude so that the connecting pin 10 is not pushed toward the printed circuit board (1).

상기 접촉부(14)는 소켓 커넥터(100)의 접속단자(110)와 접촉한다. 상기 손목부(13)는 아암부(12)와 접촉부(14)의 사이에 잘록하게 형성되어 접촉부(14)가 소켓 커넥터(100)의 접속단자(110)에 접촉될 때 접촉성을 높이게 된다. The contact part 14 contacts the connection terminal 110 of the socket connector 100. The wrist part 13 is formed to be narrow between the arm part 12 and the contact part 14 to increase contactability when the contact part 14 contacts the connection terminal 110 of the socket connector 100.

상기 아암부(12)는 탄성적으로 변형하여 상기 접촉부(14)가 소켓 커넥터(100)의 접속단자(110)에 접촉할 수 있도록 한다. The arm part 12 is elastically deformed to allow the contact part 14 to contact the connection terminal 110 of the socket connector 100.

상기 절연체(20)는 접속핀(10)을 수용하는 핀수용홈(21)을 구비하고, 상기 핀수용홈(21)의 내측벽 일측에 접속핀(10)에 대응하는 복수개의 리세스(22)가 형성되어 있다. The insulator 20 includes a pin receiving groove 21 accommodating the connection pin 10, and a plurality of recesses 22 corresponding to the connection pin 10 on one side of an inner wall of the pin receiving groove 21. ) Is formed.

상기 접촉부(14)의 일측에는 상기 리세스(22)에 삽입되는 가이드부(16)가 아래쪽으로 돌출되게 형성되어 있다. One side of the contact portion 14 is formed so that the guide portion 16 inserted into the recess 22 protrudes downward.

상기 가이드부(16)는 접촉부(14)의 아래쪽으로 돌출되어 형성됨으로써 항상 리세스(22)에 삽입된 상태로 절연체(20)에 결합된다. 즉, 상기 가이드부(16)는 상기 접촉부(14)가 소켓 커넥터(100)의 접속단자(110)와 접속하고 있을 때 뿐만 아니라 접속하고 있지 않을 때에도 항상 리세스(22)에 삽입되어 접속핀(10)이 측방으로 움직이지 않도록 가이드하게 된다. 그로 인해 접속핀(10)이 인접하는 다른 접속핀(10)과 단락(short)되지 않게 된다. The guide portion 16 is formed to protrude downward from the contact portion 14 so that it is always coupled to the insulator 20 while being inserted into the recess 22. That is, the guide part 16 is always inserted into the recess 22 not only when the contact part 14 is connected to the connecting terminal 110 of the socket connector 100 but also when not being connected to the connecting pin ( 10) is guided not to move to the side. As a result, the connecting pin 10 is not shorted with another adjacent connecting pin 10.

여기서, 상기 아암부(12)는 핀몸체(11)의 길이방향을 따라 평행하게 연장되어 형성되고, 상기 접촉부(14)는 손목부(13)에 의해 상대적으로 위쪽으로 돌출될 뿐 아암부(12)에 대하여 위쪽으로 들려지게 형성된 것은 아니며, 이와 동시에 상기 가이드부(16)가 접촉부(14)의 선단에서 손목부(13) 보다 아래쪽으로 돌출되어 있다. Here, the arm portion 12 is formed to extend in parallel along the longitudinal direction of the pin body 11, the contact portion 14 is only projected relatively upward by the wrist portion 13 arm portion 12 The guide portion 16 protrudes downward from the front end of the contact portion 14 than the wrist portion 13 at the same time.

따라서, 소켓 커넥터(100)의 접속단자(110)가 핀수용홈(21)으로 진입하여 접촉부(14)와 접촉시 핀몸체(11)에 대한 아암부(12)와 접촉부(14)의 모멘트가 최소화되어 접속핀(10)이 들뜨지 않게 된다. Accordingly, when the connecting terminal 110 of the socket connector 100 enters the pin receiving groove 21 and contacts the contact portion 14, the moment of the arm portion 12 and the contact portion 14 with respect to the pin body 11 is reduced. Minimized so that the connecting pin 10 is not raised.

즉, 상기 접촉부(14)와 가이드부(16)가 아암부(12)에 대하여 거의 평행한 연장선상에 형성됨과 동시에 그 연장선과 소켓 커넥터(100) 접속단자(110)의 진입방 향이 높이차가 작아 모멘트가 최소화되는 것이다.That is, the contact portion 14 and the guide portion 16 are formed on an extension line that is substantially parallel to the arm portion 12, and the height difference between the extension line and the socket connector 100 connecting terminal 110 is small. The moment is minimized.

한편, 접속핀(10)의 후단절곡부(15)가 절연체(20)의 외부로 돌출되어 결합됨으로써 핀몸체(11)가 절연체(20)의 중심에 배치될 수 있고, 이는 상기 접속핀(10)의 아암부(12)과 소켓 커넥터(100) 접속단자(110)의 진입방향의 높이차를 작게 한다. Meanwhile, the rear end bent portion 15 of the connecting pin 10 protrudes out of the insulator 20 to be coupled to the pin body 11, which may be disposed at the center of the insulator 20, which is the connecting pin 10. Height difference of the arm part 12 of the ()) and the socket connector 100 connection terminal 110 in the entry direction is made small.

상기 접속핀(10)은 후단절곡부(15)의 절곡된 방향에 따라 제1접속핀(10a)과 제2접속핀(10b)으로 구분되어 구비된다. 상기 제1접속핀(10a)은 인쇄회로기판(1)의 상부면 쪽으로 절곡되어 형성되고, 상기 제2접속핀(10b)은 인쇄회로기판(1)의 저면 쪽으로 절곡되어 형성된다. The connecting pin 10 is divided into a first connecting pin 10a and a second connecting pin 10b according to the bent direction of the rear bent portion 15. The first connection pin 10a is bent toward the upper surface of the printed circuit board 1, and the second connection pin 10b is bent toward the bottom surface of the printed circuit board 1.

상기 제1접속핀(10a)은 인쇄회로기판(1)의 상부면 단자에 전기적으로 접촉될 뿐만 아니라 상부면을 지지하는 역할을 하고, 상기 제2접속핀(10b)은 인쇄회로기판(1)의 저면 단자에 전기적으로 접촉될 뿐만 아니라 저면을 지지하는 역할을 한다. The first connecting pin 10a not only electrically contacts the upper surface terminal of the printed circuit board 1, but also supports the upper surface, and the second connecting pin 10b is the printed circuit board 1. It is not only in electrical contact with the bottom terminal of the but also serves to support the bottom.

상기 제1접속핀(10a)과 제2접속핀(10b)은 각각의 후단절곡부(15)가 서로 반대방향으로 배치되지만 각각의 핀몸체(11)는 동일한 높이로 절연체(20)에 결합된다. 상술한 바와 같이 제1접속핀(10a)과 제2접속핀(10b)의 각 후단절곡부(15)가 절연체(20)의 외부로 돌출됨으로써 각각의 핀몸체(11)는 절연체(20)의 중심에 위치할 수 있게 되고, 이는 아암부(12)를 핀수용홈(21)의 중앙에 위치시키게 된다. 그로 인해 아암부(12)의 높이를 소켓 커넥터(100) 접속단자(110)의 진입높이와 비슷하게 배치할 수 있게 되는 것이다.The first connecting pins 10a and the second connecting pins 10b have respective rear bent portions 15 arranged in opposite directions, but each pin body 11 is coupled to the insulator 20 at the same height. . As described above, each of the rear bent portions 15 of the first connecting pin 10a and the second connecting pin 10b protrudes out of the insulator 20, so that each of the pin bodies 11 is formed of the insulator 20. It can be located in the center, which will position the arm portion 12 in the center of the pin receiving groove (21). Therefore, the height of the arm portion 12 can be arranged to be similar to the entry height of the connection terminal 110 of the socket connector 100.

또한, 상기 후단절곡부(15)는 절연체(20)의 외측면에 지지되어 접속핀(10)이 핀수용홈(21) 쪽으로 이동하지 않도록 한다.In addition, the rear bent portion 15 is supported on the outer surface of the insulator 20 so that the connecting pin 10 does not move toward the pin receiving groove 21.
