Field of the Invention The present invention relates to a connector for connecting a circuit of a SIM (subscriber identification module) card to a circuit of a printed circuit board. In particular, an end portion of a terminal connected to a circuit of a SIM card is formed in a dome shape, and thus The present invention relates to a SIM card connector and a method of manufacturing the SIM card connected to a terminal in various directions without damaging the SIM card.
일반적으로 심(SIM;가입자정보모듈)카드란 전화번호부 등 다양한 가입자의 개인정보가 저장된 칩으로 이를 국제로밍용 CDMA(코드분할다중접속) 단말기에 연결하면 CDMA나 GSM(유럽식 이동통신방식)등과 같은 이동전화의 기술 규격에 관계없이 어느 지역에서나 자신의 전화번호로 자유롭게 이동전화를 사용할 수 있는 카드를 말한다. 이러한 심카드를 이용해 국제로밍 서비스를 받기 위해서는 단말기에 내장된 커넥터에 심카드를 직접 꽂아 연결해야 한다.In general, SIM (Subscriber Information Module) card is a chip that stores personal information of various subscribers such as phone book, and when connected to CDMA (Code Division Multiple Access) terminal for international roaming, CDMA or GSM (European mobile communication method) Regardless of the technical specifications of the mobile phone, it refers to a card that allows the user to use the mobile phone freely in his / her phone number in any region. In order to use the SIM card for international roaming service, the SIM card must be directly plugged into the connector embedded in the terminal.
종래에 심카드를 접속하기 위한 심카드 커넥터가 도 6 내지 도 8에 도시되어 있다. 도시된 바와 같이 종래의 심카드 커넥터는, 심카드의 회로접점과 접촉되도록 상측에 ‘∩’형상인 접촉부(1a)를 갖고 하측에 인쇄회로기판에 용접되는접지부(1b)를 갖는 복수 개의 터미널(1)과, 이 터미널(1)들이 고정되는 하우징(2)으로 구성된다.Conventionally, a sim card connector for connecting a sim card is shown in FIGS. 6 to 8. As shown, a conventional sim card connector has a plurality of terminals having a contact portion 1a having a '∩' shape on the upper side and a ground portion 1b welded to a printed circuit board on the lower side so as to be in contact with the circuit contact of the sim card. (1) and a housing (2) to which these terminals (1) are fixed.
이 때, 복수 개의 터미널(1)은 하우징(2)으로의 자동공급을 위해 성형단계에서 하나의 연결패널(1c)과 일체로 형성된 상태이며, 이 연결패널(1c)은 도 8에 도시된 것처럼 터미널(1)을 하우징(2)에 완전 삽입하기 전 다이(Die Plate)와 펀치(Punch)에 의해 커팅되어 터미널(1)들과 분리된다. 각 터미널(1)들은 연결패널(1c)과 분리된 후 하우징(2) 내로 완전 삽입된다.At this time, the plurality of terminals (1) is formed integrally with one connection panel (1c) in the molding step for automatic supply to the housing (2), as shown in Figure 8 Before the terminal 1 is fully inserted into the housing 2, it is cut by a die plate and a punch and separated from the terminals 1. Each terminal 1 is separated from the connecting panel 1c and completely inserted into the housing 2.
그리고, 각 터미널(1)의 상측 단부에는 하우징(2)의 상측에 걸려 접촉부(1a)가 하우징(2)의 상방으로 너무 돌출되지 않도록 하는 걸림돌기(1d)가 양측으로 형성된다.Then, at the upper end of each terminal 1, engaging projections 1d are formed on both sides so as to be caught on the upper side of the housing 2 so that the contact portion 1a does not protrude too far above the housing 2.
그러나, 종래에 전술한 바와 같이 구성된 커넥터는, 심카드의 회로접점과 접촉되는 터미널의 접촉부가 ‘∩’형상으로 형성되므로, 심카드가 전후 방향 또는 상방향에서만 접촉 가능하며 측방향에서 접촉할 경우 터미널의 접촉부 및 심카드의 회로접점이 손상되는 문제점을 가진다.However, in the connector constructed as described above, since the contact portion of the terminal which is in contact with the circuit contact of the SIM card is formed in a '∩' shape, the SIM card can be contacted only in the front-back direction or the upper direction and the side contact is made. There is a problem that the contacts of the terminal and the circuit contacts of the sim card are damaged.

이상과 같이 본 발명의 바람직한 실시예에 따른 심카드 커넥터를 첨부된 도면을 참조로 설명하였으나, 본 발명은 본 명세서에 상세히 설명된 실시예와 도면에 한정되지 아니하며, 발명의 기술사상 범위 내에서 다양한 변형이 이루어질 수 있다.As described above with reference to the accompanying drawings SIM card connector according to a preferred embodiment of the present invention, the present invention is not limited to the embodiments and drawings described in detail herein, various within the scope of the technical spirit of the invention Modifications can be made.
이상에서 상세히 설명한 바와 같이 본 발명 심카드 커넥터에 따르면, 심 카드의 회로와 접속되는 터미널의 단부를 돔형으로 형성함으로써, 심카드를 측방향, 전후방향 및 상방향중 어느 방향으로 삽입하더라도 심카드 및 터미널의 손상없이 심카드와 터미널이 서로 접속될 수 있는 장점이 있다.According to the sim card connector of the present invention as described in detail above, by forming the end of the terminal connected to the circuit of the sim card in the dome shape, the SIM card and the SIM card in any of the lateral, front and rear directions, There is an advantage that the SIM card and the terminal can be connected to each other without damaging the terminal.
또한, 본 발명에 따르면, 터미널들이 하우징에 삽입 고정될 때 터미널들의 탄력부가 하우징의 삽입홈 내에 충분히 고정되므로 터미널의 접촉부가 필요 이상으로 하우징의 상측으로부터 돌출되는 것을 방지할 수 있는 장점도 있다.Further, according to the present invention, since the resilient portions of the terminals are sufficiently fixed in the insertion groove of the housing when the terminals are inserted into and fixed to the housing, there is also an advantage of preventing the contact portion of the terminal from protruding from the upper side of the housing more than necessary.
그리고, 본 발명 심카드 커넥터의 제조방법에 따르면, 터미널을 하우징에 고정하기 전에 미리 터미널과 연결패널을 연결하는 연결부의 상면 또는 저면에 커팅홈을 형성함으로써, 터미널을 하우징에 고정한 후 별도의 다이나 펀치 없이도 연결패널을 터미널로부터 간편하게 분리할 수 있으며, 그에 따라 단말기에 내장된 인쇄회로기판에 용접되는 터미널 접지부의 평탄도를 유지할 수 있다.According to the manufacturing method of the SIM card connector of the present invention, before fixing the terminal to the housing, a cutting groove is formed on the upper or lower surface of the connecting portion connecting the terminal and the connection panel in advance, thereby fixing the terminal to the housing and then a separate dyna punch. The connection panel can be easily removed from the terminal without maintaining the flatness of the terminal ground welded to the printed circuit board embedded in the terminal.
