Description

인쇄회로기판용 커넥터 핀 구조{connector pin structure for PCB(printed circuit board)}Connector pin structure for printed circuit board

본 발명은 인쇄회로기판용 커넥터 핀 구조에 관한 것으로, 더욱 상세하게는 다른 회로와의 접속을 위해 인쇄회로기판에 장착되는 커넥터의 핀이 인쇄회로기판의 핀홀에 안정적으로 접속될 수 있도록 발명된 인쇄회로기판용 커넥터 핀 구조에 관한 것이다.The present invention relates to a connector pin structure for a printed circuit board, and more particularly, a printing invented so that a pin of a connector mounted on a printed circuit board for connection with another circuit can be stably connected to the pinhole of the printed circuit board. It relates to a connector pin structure for a circuit board.

인쇄회로기판(PCB, printed circuit board)은 전자기기의 소형화와 대량생산화에 많은 도움을 주고 있다. 이러한 인쇄회로기판은 표면 교차 접속이 불가능하므로, 회로에서 점프를 해야할 경우 등에는 다른 배선 방법을 강구해야 한다.Printed circuit boards (PCBs) are helpful in miniaturization and mass production of electronic devices. Since such a printed circuit board cannot be surface-cross connected, another wiring method must be taken when a jump in the circuit is required.

한편, 인쇄회로기판상의 회로와 접속되는 다른 회로가 있을 때에는 일반적으로 커넥터을 이용하게 되는데, 상기 커넥터에는 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, a connector is generally used, and the connector has a plurality of pins inserted into and coupled to the pinholes formed on 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 그 횡단면이 일반적으로 사각형태로 이루어져 있어서, 상기 핀이 인쇄회로기판의 핀홀에 삽입되어 결합되더라도 접속상태가 불안정하게 되고, 특히 현재와 같은 고집적회로의 인쇄회로기판에 사용되는 경우에는 미세한 접촉상태의 변화에 따라 작동불량을 야기시키는 문제가 있었다.By the way, the pin of the connector used here is generally rectangular in cross-section, even if the pin is inserted into the pinhole of the printed circuit board, the connection state becomes unstable, in particular, the printed circuit board of the high-integrated circuit When used in the case of a problem that causes a malfunction due to the change in the fine contact state.

그러므로 최근에는 상기한 문제를 해결하기 위해 핀의 형태를 도 1에서 도시하는 바와 같이 약간 개량된 형태로 구성하기도 한다. 즉, 핀(4)이 인쇄회로기판(1)의 핀홀(3)에 삽입되어 결합되는 부분에 약간 넓적한 고정부(5)를 형성하고, 상기 고정부(5)의 중앙 부분에 여유구멍(6)을 관통형성하여서 커넥터(2)의 핀(4)이 핀홀(3)에 압입되어 삽입될때 상기 고정부(5)가 탄성 또는 약간의 소성변형을 일으키면서 핀(4)이 종래의 사각형태보다는 견고하게 삽입고정된다. 이때상기 여유구멍(6)은 고정부(5)가 탄성 또는 소성변형될 수 있도록 형성되는데, 핀(4)이 핀홀(3)에 삽입되면, 초기 보다 그 폭이 감소하게 된다. 그러나 이와 같이 개량된 형태의 구조 또한 도 2에서 도시하는 바와 같이 핀(4)과 핀홀(3)이 접촉되는 부분이 고정부(5)의 양 측면으로 제한되므로 개량의 효과가 크지 않다.Therefore, in recent years, in order to solve the above problem, the shape of the pin may be slightly improved as shown in FIG. 1. That is, a slightly wider fixing portion 5 is formed in a portion where the pin 4 is inserted into and coupled to the pinhole 3 of the printed circuit board 1, and the clearance hole 6 is formed in the center portion of the fixing portion 5. The pin 4 is elastic or slightly plastically deformed when the pin 4 of the connector 2 is press-fitted into the pinhole 3 so that the pin 4 is formed in a rectangular shape. It is firmly inserted and fixed. At this time, the clearance hole 6 is formed so that the fixing portion 5 can be elastic or plastic deformation, when the pin 4 is inserted into the pin hole 3, the width is reduced than the initial. However, the structure of the improved form as shown in FIG. 2 is also limited in both sides of the fixing portion 5 as the pin 4 and the pinhole 3 is in contact with the improvement effect is not large.

본 발명은 상기의 문제를 해결하기 위해 안출된 것으로, 다른 회로와의 접속을 위해 인쇄회로기판에 장착되는 커넥터의 핀이 인쇄회로기판의 핀홀에 안정적으로 접속될 수 있도록 발명된 인쇄회로기판용 커넥터 핀 구조를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, the connector for the printed circuit board invented so that the pin of the connector mounted on the printed circuit board for the connection with other circuits can be stably connected to the pinhole of the printed circuit board. The purpose is to provide a fin structure.

상기의 목적을 달성하기 위한 본 발명은, 다른 회로와의 접속을 위해 인쇄회로기판에 장착되는 커넥터의 핀에 있어서, 인쇄회로기판의 핀홀에 고정되는 부분에 넓적한 고정부가 형성되고, 상기 고정부의 중앙 부분에는 두 지점에서 길이방향을 따라 평행하게 절개된 후 절개부위가 일측방향으로 볼록하게 프레스가공된 탄성부가 형성된 구조로 이루어진 것을 특징으로 한다.The present invention for achieving the above object, in the pin of the connector to be mounted on the printed circuit board for connection with other circuits, a wide fixing portion is formed in a portion fixed to the pinhole of the printed circuit board, The central portion is characterized by consisting of a structure formed in the elastic portion is cut in parallel in the longitudinal direction at two points and then the incision is convex in one direction.

첨부된 도면, 도 3은 본 발명에 의한 인쇄회로기판용 커넥터 핀 구조를 보이는 사시도이고, 도 4는 본 발명에 의한 인쇄회로기판용 커넥터 핀의 요부 배면 사시도이다.3 is a perspective view showing the structure of the connector pin for a printed circuit board according to the present invention, Figure 4 is a perspective view of the main portion of the back of the connector pin for a printed circuit board according to the present invention.

본 발명은 상기 도면에서 도시하는 바와 같이 인쇄회로기판(10)에 커넥터(20)가 장착될때 핀홀(11)에 삽입 고정되는 부분에 넓적한 고정부(31)가 형성되며, 상기 고정부(31)의 중앙 부분에는 탄성부(32)가 형성된 구조로 이루어진다.In the present invention, as shown in the drawing, when the connector 20 is mounted on the printed circuit board 10, a wide fixing portion 31 is formed at a portion inserted and fixed to the pinhole 11, and the fixing portion 31 The central portion of the elastic portion 32 is formed of a structure formed.

여기서 상기 탄성부(32)는 상기 고정부(31)의 중앙부분 두 지점에서 길이방향을 따라 평행하게 절개하는 랜싱가공(lancing)-판재를 일부 자르고 남겨두는 가공으로, 스크랩이 전혀 발생하지 않으며, 프레스가공과 병행하여 절단된 면을 밴딩하거나 신장성형하는게 일반적이다)후에 그 절개부분을 일측방향으로 볼록하게 되도록 프레스가공하여 형성한다. 이와 같이 형성된 탄성부(32)는 전후방향으로 탄성력을 가지게 된다.Here, the elastic part 32 is a process of cutting and leaving a part of the lancing processing (lancing) -plate which is cut in parallel along the longitudinal direction at two points of the central part of the fixing part 31, and no scrap is generated. After bending or extending the cut surface in parallel with the press working), the cut is formed by press working so as to be convex in one direction. The elastic portion 32 formed as described above has elastic force in the front-rear direction.

상기와 같은 구조로 이루어진 본 발명에 의한 핀(30)이 형성된 커넥터(20)를 인쇄회로기판(10)에 장착하게 되면, 핀(30)이 인쇄회로기판(10)의 핀홀(11)에 삽입될 때 상기 고정부(31)가 내측으로 탄성 또는 소성변형되면서 핀홀(11)에 삽입되게 되며, 이와 동시에 일측으로 볼록하게 형성된 탄성부(32) 또한 탄성변형되면서 핀홀(11)에 밀착되게 된다.When the connector 20 having the pin 30 according to the present invention having the structure as described above is mounted on the printed circuit board 10, the pin 30 is inserted into the pinhole 11 of the printed circuit board 10. When the fixing part 31 is inserted into the pinhole 11 while being elastically or plastically deformed at the inside, and at the same time, the elastic part 32 convexly formed to one side is also elastically deformed and is in close contact with the pinhole 11.

그러므로 커넥터(20)의 장착이 완료되면, 핀(30)은 도 5에서 도시하는 바와 같이 핀홀(11)에 세 부분 즉, 고정부(31)의 양 측면과 탄성부(32)의 전면이 밀착된 상태로 고정된다.Therefore, when the mounting of the connector 20 is completed, the pin 30 has three parts, ie, both sides of the fixing part 31 and the front surface of the elastic part 32, close to the pinhole 11 as shown in FIG. 5. Is fixed.

이와 같이 결합이 완료되면, 본 발명에서는 핀(30)의 고정부(31) 양 측면과 탄성부(32)가 동시에 탄성력으로 핀홀(11)에 밀착지지되므로, 종래의 사각단면을가진 핀이나 고정부에 여유구멍이 형성된 핀 구조에 비해 접촉면적이 넓고 지지력이 좋아 불량접촉을 방지할 수 있다.When the coupling is completed as described above, in the present invention, since both sides of the fixing part 31 and the elastic part 32 of the pin 30 are closely attached to the pinhole 11 by elastic force at the same time, the pin having a conventional rectangular cross section or high Compared to the fin structure with clearance holes in the government, the contact area is wider and the bearing capacity is good, preventing bad contact.

이상의 명백한 설명과 같이 본 발명은 인쇄회로기판과 커넥터의 접속시 핀의 세 부분 즉, 고정부의 양 측면 부분과 탄성부의 전면이 핀홀에 탄성 또는 소성변형상태로 완전 밀착되어 고정되므로 완전한 결합상태를 이루어 작동불량발생률을 현저히 감소시킬수 있는 효과가 있다.As described above, in the present invention, the three parts of the pins, that is, both side portions of the fixing part and the front surface of the elastic part, are completely adhered to the pinhole in a state of elasticity or plastic deformation, so that the connection between the printed circuit board and the connector is completed. This can significantly reduce the malfunction rate.
