Description

내구성이 향상된 리셉터클 커넥터 및 이의 제조 방법Durable receptacle connector and its manufacturing method
본 발명은 리셉터클 커넥터에 관한 것이다. 더욱 상세하게는 휴대용 단말기 등과 같은 전자기기의 내의 인쇄회로기판에 실장되는 리셉터클 커넥터에 관한 것이다.The present invention relates to a receptacle connector. More particularly, the present invention relates to a receptacle connector mounted on a printed circuit board in an electronic device such as a portable terminal.
커넥터는 휴대용 단말기 등과 같은 전자기기에 널리 적용되는 부품이다. 최근에 전자기기가 소형화됨에 따라 커넥터는 점점 작고 얇아지고 있다. 또한 회로기판에 실장되는 전자소자의 밀도가 높아짐에 따라 커넥터 장치에 구비되는 접촉핀(Contact)의 수도 많아지고 접촉핀 간의 배열 피치(Pitch) 또한 매우 좁아지고 있다.The connector is a component widely applied to an electronic device such as a portable terminal. With the recent miniaturization of electronic devices, connectors are becoming smaller and thinner. In addition, as the density of electronic devices mounted on a circuit board increases, the number of contact pins provided in the connector device increases, and the arrangement pitch between the contact pins also becomes very narrow.
통상적으로 커넥터는 다수의 리셉터클 접촉핀(Receptacle contact)이 리셉터클 인슐레이터(Receptacle insulator)에 설치된 리셉터클 커넥터와, 리셉터클 접촉핀과 일대일 접촉하는 다수의 플러그 접촉핀(Plug contact)이 플러그 인슐레이터(Plug insulator)에 설치된 플러그 커넥터로 구성된다.In general, a connector includes a receptacle connector having a plurality of receptacle contact pins installed in a receptacle insulator, and a plurality of plug contact pins having a one-to-one contact with the receptacle contact pins to a plug insulator. It consists of a plug connector installed.
리셉터클 접촉핀과 플러그 접촉핀은 각각 리셉터클측 케이블 및 플러그측 케이블에 연결되거나 회로기판에 실장된다. 리셉터클에 플러그를 끼워 리셉터클 접촉핀과 플러그 접촉핀이 상호 접촉되도록 하면 리셉터클측 케이블과 플러그측 케이블 또는 회로기판들의 회로가 전기적으로 연결된다. 그리하여 외부 기기와 데이터 통신을 하거나 전원이 공급된다.The receptacle contact pin and the plug contact pin are respectively connected to the receptacle side cable and the plug side cable or mounted on a circuit board. When the plug is inserted into the receptacle so that the receptacle contact pin and the plug contact pin contact each other, the circuit of the receptacle side cable and the plug side cable or the circuit boards are electrically connected. Thus, data communication or power is supplied to the external device.
그런데 커넥터는 사용 시에 열충격을 받으므로, 장시간 사용하면 열변형이 발생할 수 있다. 이로 인하여 플러그 커넥터와 리셉터클 커넥터의 접촉이 불량해지고, 단락으로 발화 또는 영구 변형이 발생할 수 있다.However, since the connector is subjected to thermal shock during use, thermal deformation may occur when used for a long time. This may result in poor contact between the plug connector and the receptacle connector, and may cause fire or permanent deformation due to a short circuit.
