본 발명은 인쇄회로 기판용의 커넥터핀에 관한 것으로, 더욱 상세하게는 인쇄회로 기판에 핀을 끼우고 압입하여, 상기 기판에 핀이 끼워지는 삽입홀 패턴 전면을 핀이 감싸주게 되어 충격과 진동에 의한 안정성이 좋아지는 인쇄회로 기판용의 땜납없는 핀에 관한 것이다. The present invention relates to a connector pin for a printed circuit board, and more particularly, by pinning and inserting a pin into a printed circuit board, the pin surrounds the entire surface of the insertion hole pattern into which the pin is inserted into the board. The present invention relates to a solderless pin for a printed circuit board with improved stability.

인쇄회로기판(PCB,Printed circuit board)은 전자기기의 소형화와 대량생산 화에 많은 도움을 주고 있다. 이러한 인쇄회로기판은 표면 교차 접속이 불가능하므로, 회로에서 점프를 해야할 경우등에는 다른 배선 방법을 강구해야한다.Printed circuit boards (PCBs) have helped in miniaturization and mass production of electronic devices. Since these printed circuit boards cannot be surface-cross connected, other wiring methods should be taken when jumping from the circuit is required.

한편, 인쇄회로기판상의 회로와 접속되는 다른 회로가 있을때에는 일반적으로 커넥터를 이용하게 되는데, 상기 커낵터에는 인쇄회로기판에 형성된 핀홀에 삽입되어 결합되는 핀이 다수 형성되어 있다. 이와 같이 형성된 커넥터를 상기 핀이 핀홀에 삽입되도록 결합시키고, 다른 커넥터를 상기 커넥터와 결합시켜 다른 회로와 접속시키게 되는 것이다. On the other hand, when there are other circuits connected to the circuit on the printed circuit board is generally used a connector, the connector is formed with a plurality of pins that are inserted into the pin hole formed in the printed circuit board. The connector thus formed is coupled to insert the pin into the pinhole, and the other connector is coupled to the connector to be connected with another circuit.

그런데, 여기서 사용되는 커넥터의 핀은 도 1에 도시된바와 같이, 그 횡단면은 내경이 1차 축소되어 마련된 1차 단차부(1a)와, 상기 1차 단차부와 연장되어 마련되되 그 양측이 둥근 타원모양의 변형부(1b)와, 상기 변형부(1b)와 연결되어 그 끝단이 다시 내경이 축소된 2차단차부(1c)가 마련된다. 또한, 상기 핀(1)이 삽입되는 핀홀(3)이 PCB(2)에 마련된다. By the way, the pin of the connector used here, as shown in Figure 1, the cross section is provided with an extension of the primary stepped portion (1a) and the primary stepped portion is provided that the inner diameter is primarily reduced, the both sides are rounded An elliptic deformable portion 1b and a secondary stepped portion 1c connected to the deformable portion 1b and whose end is reduced in diameter again are provided. In addition, a pinhole 3 into which the pin 1 is inserted is provided in the PCB 2.

이러한 상기 커넥터의 핀(1)에 PCB(2)를 직접 누름으로 해서 PCB(2)의 응력이 가해지면서 PCB(2)의 휨현상이 발생하게 되고, 상기 PCB(2)위에 고정된 민감한 전기소자들이 응력을 받아서 불안해지게된다. 또한, 압입후 핀(1)과 핀홀(3)이 패턴(4)이 맞닿는 면적이 작기 때문에 큰 전류를 흘리는데 있어 문제가 발생하게 된다. By pressing the PCB (2) directly to the pin (1) of the connector is the stress of the PCB (2) is applied to the bending phenomenon of the PCB (2) occurs, the sensitive electrical elements fixed on the PCB (2) You get stressed and uneasy. In addition, since the area where the pins 1 and the pinholes 3 contact the pattern 4 after the press-fitting is small, a problem arises in flowing a large current.

본 발명은 이러한 문제를 해결하기 위해 안출된 것으로, 커넥터 핀의 구조를 변형하여, PCB에 가해지는 응력을 감소시킴과 동시에 전기소자의 안정성이 보장되 는 인쇄회로기판의 커넥터핀을 제공하는 것이다. SUMMARY OF THE INVENTION The present invention has been made to solve this problem, and provides a connector pin of a printed circuit board that is modified by the structure of the connector pin, reducing the stress applied to the PCB and at the same time ensure the stability of the electrical device.

이와 같은 문제점을 해결하기 위한 본 발명은,The present invention for solving such a problem,

다른 회로와의 접속을 위해 인쇄회로기판에 장착되는 커넥터핀에 있어서,In a connector pin mounted on a printed circuit board for connection with other circuits,

상기 핀은 PCB에 마련된 핀홀에 끼워지는 부분이 내경이 축소되어 단차지게 마련된 것을 특징으로 한다.The pin is characterized in that the part is fitted into the pin hole provided in the PCB is reduced in diameter to be stepped.

이러한 본 발명에 따른 인쇄회로기판용 커넥터핀은 도 2에 도시된 바와 같이, 상기 PCB(12)의 핀홀(13)에 삽입되는 부분의 내경(17)이 축소되어 단차지게 마련되며, 그 끝단은 둥근모양으로 마련된다. 상기 핀(10)이 PCB(12)의 핀홀(13)에 삽입되는 부분의 내경(17)이 축소되어 마련되어 있기 때문에 PCB(12)에 응력이 작용하지 않게 된다. As shown in FIG. 2, the connector pin for the printed circuit board according to the present invention is provided to be stepped by reducing the inner diameter 17 of the portion inserted into the pinhole 13 of the PCB 12. It is provided in a round shape. Since the inner diameter 17 of the portion where the pin 10 is inserted into the pinhole 13 of the PCB 12 is reduced, the stress is not applied to the PCB 12.

또한, 상기 핀(10)이 PCB(12)의 핀홀(13)에 삽입된후, 상기 핀홀(13)을 통과한 핀(10)을 커넥터 누름기구(11)를 이용해서 눌러주게 되는데, 이로 인해서 상기 핀(10)이 압입되어 핀(10)이 핀홀 패턴(14) 전면을 감싸주므로, 전도성이 훨씬 좋아지게 된다.In addition, after the pin 10 is inserted into the pinhole 13 of the PCB 12, the pin 10 passing through the pinhole 13 is pressed using the connector pressing mechanism 11, thereby Since the pin 10 is pressed in and the pin 10 surrounds the entire surface of the pinhole pattern 14, the conductivity becomes much better.

이상에서 설명한 바와 같이, PCB의 핀홀에 삽입되는 핀이 내경이 축소된 단차부가 마련되어 상기 단차부가 핀홀에 삽입되면서, 상기 PCB에 응력이 작용하지 않게 되어 전기소자의 안정성을 보장할 뿐만아니라, 압입후에는 기구를 이용하여 핀을 눌러 상기 핀이 핀홀 패턴 전면을 감싸주게 되므로 전도성이 훨씬 좋아지게 되며, 상기 핀홀에 핀이 튼튼하게 고정되며, 충격이나 진동으로부터 안정성이 확보가 되는 작용효과가 있다. As described above, as the pin inserted into the pinhole of the PCB is provided with a stepped portion having a reduced inner diameter, the stepped portion is inserted into the pinhole, so that the stress is not applied to the PCB, thereby ensuring the stability of the electric device and after the press-fitting. Since the pin is pressed using a mechanism to surround the front surface of the pinhole pattern, the conductivity becomes much better, the pin is firmly fixed to the pinhole, and there is an effect of securing stability from shock or vibration.
