Description

인쇄회로기판용 접촉식 커넥터구조{A contact type connector for printed circuit board}Contact connector structure for printed circuit boards {A contact type connector for printed circuit board}

본 발명은 이동통신 단말기의 인쇄회로기판(이하, "PCB"라 칭함)에 설치된 커넥터에 관한 것으로, 특히 좁은 간격으로 다수의 핀들이 실장된 커넥터에 외부 부품을 접촉하였을 때 부품의 들뜸이나, 형상의 변형을 방지할 수 있는 인쇄회로기판용 접촉식 커넥터 구조에 관한 것이다. The present invention relates to a connector installed on a printed circuit board of the mobile communication terminal (hereinafter referred to as "PCB"), in particular, when the external components contact the connector mounted with a plurality of pins at a narrow interval, the shape of the component, It relates to a contact connector structure for a printed circuit board that can prevent the deformation of the.

일반적으로, 휴대폰이나 PDA등과 같은 단말기에는 다수의 부품을 실장하기 위한 인쇄회로기판이 설치되며, 이 인쇄회로기판에는 각종 데이터를 디스플레이하는 액정표시장치가 접촉식 커넥터를 매개로 접속되어 있다.In general, a terminal such as a mobile phone or a PDA is provided with a printed circuit board for mounting a plurality of components, and a liquid crystal display for displaying various data is connected to the printed circuit board via a contact connector.

이러한 PCB의 구조를 도1 및 도2를 참조하여 간략히 설명한다.The structure of such a PCB will be briefly described with reference to FIGS. 1 and 2.

도1은 종래 기술에 따른 PCB용 커넥터의 구성을 나타낸 단면도이며, 도2는 종래 기술에 따른 PCB용 커넥터에 LCD를 접촉시킨 상태를 나타낸다.1 is a cross-sectional view showing the configuration of a PCB connector according to the prior art, and FIG. 2 shows a state in which the LCD is brought into contact with the PCB connector according to the prior art.

도1에 도시된 바와 같이, 상기 PCB(100)에는 좁은 간격(narrow pitch)으로 많은 핀(102)들을 실장한 접촉식 커넥터(101)가 설치되어 있으며, 상기 커넥터(101)에는 각종 부품이 끼워져 전기적 접촉을 수행한다.As shown in FIG. 1, the PCB 100 is provided with a contact connector 101 mounted with many pins 102 at a narrow pitch, and various components are inserted into the connector 101. Perform electrical contact.

상기 좁은 간격의 많은 핀(102)들을 갖는 종래의 접촉식 커넥터(101)에 그에 적합한 부품, 예를들어 15핀 커넥터에 그에 맞는 15핀홀을 갖는 부품을 접촉시키기 위해서는 상기 부품의 양쪽 끝을 PCB(100)상에 고정시키게 된다. 이 경우, 커넥터(101)에 실장된 각각의 핀(102)들에 반발력이 발생하게 되고, 이러한 반발력은 핀들을 커넥터(101)의 중앙으로 오므라들게 하는 현상을 유발하여 결국 커넥터(101)의 중앙부분에서 부품이 들뜨는 현상이 발생한다.In order to contact a conventional contact connector 101 having a large number of pins 102 with a narrow gap therefor, a suitable component, for example, a component having a 15-pin hole corresponding to a 15-pin connector, may be connected to both ends of the PCB. 100). In this case, a repulsive force is generated in each of the pins 102 mounted on the connector 101, and this repulsive force causes the pins to retract to the center of the connector 101, resulting in the center of the connector 101. The lifting of parts occurs in the part.

이는 근본적으로 접촉시킬 부품을 커넥터의 양 끝에서만 고정시키는데 원인이 있으며, 이로 인해 커넥터(101)의 끝단은 부품과 강하게 접촉할 수 있으나, 중간부분은 지지해 주는 것이 없으므로 핀(102)들의 반발력에 의해 부품이 들어올려지게 되어 부품의 들뜸이나, 심할 경우에는 부품의 형상변형을 일으키는 문제점이 있다. 이를 해결하기 위해서는 커넥터(101)의 중간부분도 PCB에 고정시켜야 하는데, 대부분의 경우 실제 커넥터의 중간부분에 지지시키기 위한 부재를 설치하는데 많은 문제점이 발생하고, 이로 인해 접촉자체가 불가능해질 수 있다. This essentially causes the parts to be contacted to be fixed only at both ends of the connector, so that the end of the connector 101 can be in strong contact with the part, but the middle part has no support, so the repulsive force of the pins 102 As a result, the component is lifted, and there is a problem that the component is lifted up or, in the case of severe, causing the shape deformation of the component. In order to solve this problem, the middle portion of the connector 101 should also be fixed to the PCB. In most cases, many problems occur in installing a member for supporting the middle portion of the actual connector, which may make the contact itself impossible.

도2는 PCB(100)의 접촉식 커넥터(101)에 액정 표시장치인 LCD(103)를 접촉한 상태를 보여주고 있다. 2 shows a state in which the LCD 103, which is a liquid crystal display, is brought into contact with the contact connector 101 of the PCB 100. As shown in FIG.

도면에 도시된 바와 같이 상기 PCB(100)상에 장착된 커넥터(101)에 LCD(103)를 접촉시켰을 경우에 핀(102)들의 반발력에 의해 커넥터(101)의 중간부분이 들뜨게 되는 현상을 볼수 있다. 이러한 들뜸현상은 오랜 시간 동안 방치하였을 경우에 상기 LCD의 형상변형을 일으킬 수 있으며, 결국에는 크랙으로 이를 수도 있는 것이다.As shown in the figure, when the LCD 103 is brought into contact with the connector 101 mounted on the PCB 100, the middle part of the connector 101 is lifted due to the repulsive force of the pins 102. have. This lifting phenomenon may cause shape deformation of the LCD when left for a long time, and may eventually lead to cracking.

현재 적용하는 커넥터 방식은 상기에서 제시한 문제점을 해결하기 위한 방법으로써 보통 15핀 이상의 커넥터는 사용하지 않고 있으며, 이 밖에 납땜(soldering) 방식이나 제브라(zebra)방식이 제안되어 있다. 그러나, 전자의 납땜방식은 부품 자동실장이 불가능하기 때문에 수작업공정이 추가되어야 하는 문제점이 있으며, 후자의 제브라 방식은 원가가 상승하는 문제점이 있다. The currently applied connector method is a method for solving the above problems, and usually a connector of 15 pins or more is not used. In addition, a soldering method or a zebra method has been proposed. However, the former soldering method has a problem that a manual process is added because the automatic mounting of parts is impossible, the latter zebra method has a problem that the cost increases.

따라서, 본 발명은 상기한 바와 같은 제반 문제점을 해결하기 위하여 제안된 것으로, PCB상에 커넥터 설치시 커넥터 핀의 높이를 달리하여, 즉 외곽에서 중간부로 갈수록 핀의 높이를 낮게 함으로써 핀들간의 반발력을 감소시킴으로써 외부 부품을 커넥터에 실장하였을 때에는 커넥터핀 전체가 평행하게 부품과 접촉할 수 있도록 한 인쇄회로기판용 접촉식 커넥터구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been proposed to solve the above problems, by reducing the height of the connector pin when installing the connector on the PCB, that is, by lowering the height of the pin from the outer to the middle portion to reduce the repulsive force between the pins The purpose of the present invention is to provide a contact connector structure for a printed circuit board in which the entire connector pin is in contact with the component in parallel when the external component is mounted on the connector.

상기 목적을 달성하기 위한 본 발명은, 각종 부품을 실장하기 위한 인쇄회로기판용 접촉식 커넥터상에 소정 피치간격으로 다수의 핀이 직립되게 실장되되, 상기 핀들이 양끝단에서 중간부로 갈수록 점차적으로 소정 높이만큼 낮은 높이를 갖는 것을 특징으로 하는 인쇄회로기판용 접촉식 커넥터구조를 제공한다.The present invention for achieving the above object, a plurality of pins are mounted upright at a predetermined pitch interval on the contact connector for a printed circuit board for mounting a variety of parts, the pins are gradually predetermined from both ends to the middle portion Provided is a contact connector structure for a printed circuit board having a height as low as a height.

이하, 본 발명의 바람직한 실시예를 도3 및 도4를 참조하여 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to FIGS. 3 and 4.

본 발명에 의한 인쇄회로기판용 커넥터구조는 핀들간의 반발력을 최소화하여 각종 부품을 커넥터에 접촉시 들뜸을 방지할 수 있도록 구현한 것으로, 본 발명의 실시예에서는 도3에 도시된 바와 같이 각종 부품을 실장하기 위한 인쇄회로기판(1)용 접촉식 커넥터(2)상에 소정 피치간격으로 다수의 핀(3)이 직립되게 실장되되, 상기 핀(3)들이 양끝단에서 중간부로 갈수록 점차적으로 소정 높이만큼 낮은 높이를 갖도록 설계되어 있다.The connector structure for a printed circuit board according to the present invention is implemented to prevent the lifting of the various parts in contact with the connector by minimizing the repulsive force between the pins, in the embodiment of the present invention as shown in Figure 3 A plurality of pins 3 are mounted upright on a contact connector 2 for a printed circuit board 1 to be mounted at a predetermined pitch interval, and the pins 3 gradually become a predetermined height from both ends to the middle part. It is designed to have a height as low as possible.

이와같이 커넥터(2)의 양끝단부의 핀들과 중간부의 핀들간에 높이차를 부여함으로써, 부품을 실장하였을 경우에, 커넥터(2)의 중간측으로 오무라드는 현상이 방지된다.By providing a height difference between the pins at both ends of the connector 2 and the pins at the middle of the connector 2 in this way, when the component is mounted, the phenomenon of squeaking toward the middle of the connector 2 is prevented.

따라서, 도4에 도시된 바와 같이 일예로 액정표시장치인 LCD(4)를 PCB(1)상의 커넥터(2)에 접촉시켰을 경우에, 상기 LCD(4)의 양끝단부와 커넥터(2)의 양끝단 핀들이 강하게 접촉함과 동시에 커넥터(2)의 중간부에 위치한 핀들은 그의 높이가 양끝단부 핀들의 높이보다 낮게 형성되어 있으므로 반발력이 저하되어 오무라드는 것이 아니라, 반대로 상승하게 됨으로써 상기 LCD(4)는 전체면에 걸쳐 평행하게 커넥터핀(3)들과 접촉하게 되는 것이다. Therefore, as shown in FIG. 4, when the LCD 4, which is a liquid crystal display device, is brought into contact with the connector 2 on the PCB 1, for example, both ends of the LCD 4 and both ends of the connector 2 are shown. However, since the pins are in strong contact with each other and the pins positioned at the middle of the connector 2 are lower than the heights of the pins at both ends thereof, the repulsive force is not lowered, and the pins are raised. ) Is to be in contact with the connector pins 3 in parallel across the entire surface.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능하다는 것이 본 발명이 속하는 분야에서 통상의 지식을 가진 자에게 있어서 명백할 것이다.The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and it is common in the field of the present invention that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

전술한 바와 같이 본 발명에 따르면, 인쇄회로기판상에 다수의 부품을 실장하기 위한 커넥터에 있어서, 좁은 간격으로 실장된 다수의 핀들중에서 양끝단부의 핀들높이보다 중간부의 핀들 높이를 점차적으로 작게 형성하여 중간부분에서의 각 핀들간의 반발력을 감소시킴으로써, 부품 실장시 들뜸없이 전면에 걸쳐 평행하게 접촉할 수 있으며, 이에 따른 가격상승이나, 추가적인 수작업공정을 없앨 수 있는 효과가 있다.As described above, according to the present invention, in the connector for mounting a plurality of components on a printed circuit board, among the plurality of pins mounted at narrow intervals, the height of the middle pins is gradually smaller than the height of the pins at both ends. By reducing the repulsive force between the pins in the middle part, it is possible to contact in parallel across the front without lifting during component mounting, thereby increasing the price or eliminate the additional manual process.
