Description
본 발명은 패드결합요홈이 형성된 회로기판에 관한 것으로, 특히 전기적 접속을 하고자 인쇄기판 중 한쪽 인쇄기판에는 엣지 컨넥터(이하, '컨넥터'라 함)에 상하 2열로 다수의 연결단자핀을 형성하고, 상기 컨넥터에 상하로 배열된 컨넥터 연결단자핀 사이에 결합시켜 전기적으로 연결하는 패드결합요홈이 형성된 회로기판에 관한 것이다.The present invention relates to a circuit board having a pad coupling recess, and in particular, one of the printed circuit boards has a plurality of connection terminal pins formed in two rows of upper and lower edge connectors (hereinafter referred to as 'connectors') in one of the printed boards for electrical connection. The present invention relates to a circuit board having a pad coupling groove for coupling and electrically connecting between connector connecting terminal pins arranged up and down on the connector.
각종 전기 전자 혹은 전자응용기기의 전자회로는 각종 능동소자 및 수동부품 또는 기구를 포함하는 인쇄회로기판(이하, '회로기판'이라 함)상에 배치하여 형성된다.Electronic circuits of various electric and electronic applications are formed on a printed circuit board (hereinafter, referred to as a "circuit board") including various active elements and passive components or mechanisms.
서로 떨어진 회로기판과의 접속을 위하여 다양한 형상의 리셉터클타입(암형) 컨넥터 및 이에 결합하는 플러그타입(숫형) 컨넥터가 널리 사용되고 있다.Various types of receptacle type (female) connectors and plug type (male) connectors coupled thereto are widely used for connecting to separate circuit boards.
도 1은 종래의 회로기판 결합을 나타낸 컨넥터의 사시도이다.1 is a perspective view of a connector showing a conventional circuit board coupling.
일반적으로, 컨넥터의 복수의 단자를 회로기판(10)의 단부 근방의 접속패드(14)에 접속하기 위해서는 개별적으로 납땜을 하거나, 일괄적으로 플로우 납땜(flow solder)을 하여 한쪽 기판에는 리셉터클(암형) 컨넥터(12)를 장착하고 이와 접속되는 다른 기판에는 플러그(숫형) 컨넥터(12')를 장착하여 양 컨넥터를 결합함으로써 양 회로기판을 전기적으로 결합시킨다.In general, in order to connect the plurality of terminals of the connector to the connection pad 14 near the end of the circuit board 10, soldering is performed individually or flow soldering is performed on one board to receptacle (female type). 2) The connector 12 is mounted, and a plug (male) connector 12 'is mounted on the other substrate connected thereto to electrically connect both circuit boards by coupling the two connectors.
최근 전자기기가 소형화되고 회로구성 기술이 발달됨에 따라 점점 더 소형화된 컨넥터가 요구되고 이에 부응하여 컨넥터의 핀과 핀간의 거리가 작아지는 추세이나, 컨넥터의 구성상 적정한 기계적 강도와 절연상의 문제로 컨넥터가 전자기기의 소형화에 장해 요인으로 부각되고 있으며, 특히 회로기판과 컨넥터의 접속을 위하여 접속패드와 일치시켜 납땜 등으로 접속하여야 하나 접속패드사이의 이격거리가 적어서 컨넥터 접속이 제품의 불량요인으로 작용하고 생산원가를 상승시키게 되고, 컨넥터가 전자제품 소형화에 장해요인으로 작용하고 있다.Recently, as electronic devices have been miniaturized and the circuit construction technology has been developed, more and more miniaturized connectors are required and the pin-to-pin distances of the connectors become smaller in response to these problems.However, due to the proper mechanical strength and insulation problems in the connector configuration, Is an obstacle to the miniaturization of electronic devices. Especially, in order to connect the circuit board and the connector, it must be connected with the connection pad by soldering, etc., but the distance between the connection pad is small, so the connector connection acts as a bad factor of the product. In addition, the cost of production increases, and connectors are acting as a barrier to miniaturization of electronic products.
도 1에 도시된 바와 같이, 양면회로기판과 컨넥터를 결합하기 위하여 컨넥터의 연결단자핀(13)을 절곡하여 회로기판 일면의 접속패드(14)에 납땜에 의하여 접속하고 하면에 접속패드와의 접속을 위해서는 회로기판을 천공하여 연결단자핀을 하면의 접속패드와 연결하여 컨넥터를 회로기판상에 배치시킨다. 그러나, 이는 연결핀과의 접속을 위하여 회로기판 천공 등의 작업공정의 어려움과 회로기판상에 컨넥터가 탑재됨으로써 제품의 높이가 증가하는 문제점을 내포하고 있다.As shown in FIG. 1, the connecting terminal pin 13 of the connector is bent to connect the double-sided circuit board and the connector, and connected to the connection pad 14 on one side of the circuit board by soldering, and the connection with the connection pad on the lower surface. To do this, drill the circuit board and connect the connector pins with the connection pads on the bottom to place the connector on the circuit board. However, this implies the difficulty of a work process such as punching a circuit board for connection with a connecting pin and increasing the height of a product by mounting a connector on the circuit board.
이를 개선하기 위하여, 도 2에 도시된 바와 같이, 접속패드가 형성된 양면 회로기판을 연결단자핀의 길이를 컨넥터케이스(11)보다 길게 하고 길게 인출된 연결단자핀(13)의 상하 열 사이에 삽입하고 연결단자핀과 접속패드를 일치시켜 납땜 등의 처리를 하여 컨넥터를 회로기판에 고정한다. 그러나, 이는 접속패드의 중심부에 연결단자핀(13)을 일치시켜 납땜을 하기 위하여 작업자의 숙련도가 요구되고, 컨넥터핀의 간격이나 크기는 국제표준규격으로 동일하지만 컨넥터 케이스(11)는 제작사 마다 사내규격을 사용하므로 각기 달라 크기나 모양으로 패드와 컨넥터핀의 중심을 다수의 제품에 맞출 수 없어 이를 일치시키기 위하여 별도의 지그가 필요하다는 문제점이 있다. 또한, 제품의 높이는 낮출 수 있으나 길이가 길어지는 단점과 회로기판상에 접속패드를 위한 도체부가 형성됨으로서 회로기판은 전체적으로 접속패드의 두께만큼 두껍게 되며 이 접속패드 상부에 연결단자핀이 접속되므로 회로기판을 연결단자핀 사이로 삽입하면 접속패드 단부는 연결단자핀의 접촉부와 일치되나 연결단자핀 단부는 벌어지게 되어 접속패드와 이격하게 되어 양호한 접속이 되지 않기 때문에 납땜 시에도 이격부에 납땜불량이 생기는 등의 문제점을 가지고 있다.In order to improve this, as shown in FIG. 2, the double-sided circuit board on which the connection pad is formed is inserted between the upper and lower rows of the connection terminal pins 13 with the length of the connection terminal pins longer than that of the connector case 11. Solder the connectors to the circuit board by matching the connector pins with the connection pads. However, this requires the operator's skill in order to match the connection terminal pin 13 to the center of the connection pad and requires soldering. The connector pins have the same spacing and size as the international standard, but the connector case 11 is manufactured in-house for each manufacturer. Since the standard uses different sizes and shapes, the center of the pad and the connector pin cannot be matched to many products, so there is a problem in that a separate jig is required to match them. In addition, the height of the product can be lowered, but the length is long, and the conductor part for the connection pad is formed on the circuit board, so that the circuit board becomes thick as the thickness of the connection pad as a whole, and the connection terminal pin is connected to the upper part of the circuit board. Is inserted between the connecting terminal pins, the connection pad end is matched with the contact part of the connecting terminal pin, but the connecting terminal pin end is opened so that it is spaced apart from the connection pad, so that poor connection is not possible even during soldering. Has a problem.
본 발명의 목적은 컨넥터와 회로기판을 접속함에 있어 컨넥터케이스 내부에 형성된 연결핀 사이로 접속패드 형성부를 삽입함으로써 납땜의 필요가 없는 구조의 패드결합요홈이 형성된 회로기판을 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a circuit board having a pad coupling groove having a structure that does not require soldering by inserting a connection pad forming portion between connecting pins formed inside a connector case when connecting a connector and a circuit board.

A circuit board inserted between a connector having a pin and a row of connection terminal pins of the connector and having a connection pad connected to the connection terminal pin at an end thereof, wherein a center portion of the connection pad is formed so that the connection terminal pins can be coupled to each other. The pad coupling groove is not formed, and the pad coupling groove and the connection terminal pin are elastically coupled to enter the center portion so as not to be eccentrically left and right along the pad coupling groove, thereby coupling the connector and the circuit board.
이하에서는 첨부한 도면을 참조하여 본 발명의 양호한 실시예에 따라 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail according to a preferred embodiment of the present invention.
도 3은 본 발명에 따른 회로기판의 결합사시도이고, 도 4는 본 발명에 따른 접속패드와 연결단자핀의 결합상태를 도시한 분리 사시도이고, 도 5a는 본 발명에따른 접속패드의 부분사시도이며, 도 5b 및 도5c는 본 발명에 따른 접속패드의 부분확대도이다.Figure 3 is a perspective view of a bonded circuit board according to the present invention, Figure 4 is an exploded perspective view showing a coupling state of the connection pad and the connection terminal pin according to the present invention, Figure 5a is a partial perspective view of the connection pad according to the present invention. 5B and 5C are partially enlarged views of a connection pad according to the present invention.
먼저, 도 3에 도시된 바와 같이, 회로기판(10)의 단부에 형성된 접속패드와 이에 결합하는 직사각형의 절연체로 된 컨넥터케이스(11)와 이 케이스 내부에 상 하 2열로 다수의 연결 단자핀(13)이 고정 배치되어 있다.First, as shown in FIG. 3, a connector case 11 formed of a connection pad formed at an end of a circuit board 10 and a rectangular insulator coupled thereto, and a plurality of connection terminal pins in two rows above and below the case are formed. 13) is fixedly arranged.
이때, 상하 연결단자핀(13)간의 거리는 회로기판(10)의 두께와 같거나, 0.1mm 정도 작으며 본 분야에서 통상적으로 사용되는 기판의 두께인 1.6 mm이다.At this time, the distance between the upper and lower connection terminal pin 13 is equal to the thickness of the circuit board 10, or less than about 0.1mm is 1.6 mm, the thickness of the substrate commonly used in the art.
상기 연결단자핀(13)은 상기 컨넥터 케이스(11) 후방으로 케이스를 관통하여 다른 전자회로와 납땜으로 연결되어 있다.The connection terminal pin 13 penetrates the case to the rear of the connector case 11 and is connected to another electronic circuit by soldering.
미도시되었지만 회로기판과의 기계적 접속을 공고히 하기 위하여 케이스 양측면에 부착고정부를 배설할 수도 있다.Although not shown, attachment fixing parts may be provided on both sides of the case to secure mechanical connection with the circuit board.
다음은 상기 2열로 배설된 연결단자핀(13)의 상하 열 사이에 결합되는 회로기판의 접속패드구조로서 접속패드는 회로기판 양면에 배설된 회로기판의 전자회로와 연결되어 회로기판 양면에 형성되고, 패드간 간격은 접속될 상기 컨넥터의 연결단자핀의 좌우 간격과 동일하고, 회로기판의 두께는 상기 컨넥터의 연결단자핀 상하 간격과 동일하거나 크다.Next, the connection pad structure of the circuit board coupled between the upper and lower rows of the connection terminal pins 13 arranged in two rows, the connection pad is connected to the electronic circuit of the circuit board disposed on both sides of the circuit board and formed on both sides of the circuit board. The spacing between the pads is equal to the left and right spacing of the connecting terminal pins of the connector to be connected, and the thickness of the circuit board is equal to or greater than the upper and lower spacing of the connecting terminal pins of the connector.
접속되는 회로기판의 접속패드는 회로기판상에 소정의 두께의 납 등의 도전체로 형성되고 형성된 접속패드의 중앙부위에 상기 컨네터의 연결접속핀(13)의 폭과 길이만큼 도전막이 형성되어 있지 않은 패드결합요홈(16)이 형성되어 있다. 이 패드결합요홈(16)은 접속패드(14)의 도전막의 두께만큼의 요홈이 형성된 것이며 이때 도전막의 두께는 본 분야에서 관용적으로 실시되는 소정의 두께이나 통상적으로 0.04mm가 적합하므로 회로기판 접속패드의 중앙부에는 단자핀과 결합하는 패드결합요홈(16)이 깊이(C)가 0.04mm 의 요홈으로 형성된다.The connection pad of the circuit board to be connected is formed of a conductor such as lead having a predetermined thickness on the circuit board, and a conductive film is formed on the center portion of the connection pad formed by the width and length of the connection connecting pin 13 of the connector. Pad coupling groove 16 is formed. The pad coupling groove 16 is formed with grooves equal to the thickness of the conductive film of the connection pad 14, and the thickness of the conductive film is a predetermined thickness or conventional 0.04 mm, which is conventionally practiced in the art, so that the circuit board connection pad is suitable. The center portion of the pad coupling groove 16 is coupled to the terminal pin is formed with a groove (C) of depth 0.04mm.
상기 패드결합요홈(16)은 도 5b에 도시된 바와 같이, 패드결합요홈(16)의 단부(A) 폭은 상기 컨넥터의 연결단자핀(13) 폭의 90~100%로 동일하거나 적게하며, 단부에서 회로기판내부로 갈수록 좁아지게 하여 컨넥터의 연결단자핀(13)의 단부가 접속되는 패드결합요홈(16) 내측(B)의 폭은 연결단자핀(13) 폭의 40~50%로 하여 패드결합요홈(16)의 형상이 사다리꼴의 요홈이 되도록 하거나, 도 5c에 도시된 바와 같이, 단부(A)와 내측(B)의 폭이 연결단자핀(13)의 폭의 40~80%로 되는 일자형 요홈으로 할 수도 있다.As shown in FIG. 5B, the width of the end A of the pad coupling recess 16 is equal to or smaller than 90 to 100% of the width of the connector pin 13 of the connector. The width of the inner side (B) of the pad coupling groove 16 to which the end of the connecting terminal pin 13 of the connector is connected is 40 to 50% of the width of the connecting terminal pin 13. The shape of the pad coupling groove 16 is a trapezoidal groove, or as shown in Figure 5c, the width of the end (A) and the inner side (B) is 40 to 80% of the width of the connecting terminal pin (13) It can also be a straight groove.
상기한 컨넥터케이스 내부에 배설된 연결단자핀(13)의 상하열 사이에 패드결합요홈(16)이 형성된 접속패드(14)가 형성된 회로기판(10) 단부를 연결단자핀(13)의 상하열 사이에 삽입하면 연결단자핀(13)은 패드결합요홈(16)에 결합되어 좌우 이동이 제한된다.The upper and lower rows of the connection terminal pins 13 are connected to the ends of the circuit board 10 on which the connection pads 14 having the pad coupling grooves 16 are formed between the upper and lower rows of the connection terminal pins 13 disposed in the connector case. When inserted between the connecting terminal pin 13 is coupled to the pad coupling groove 16 is limited to the left and right movement.
즉, 연결단자핀(13)의 끝부분은 패드결합요홈(16)이 사다리꼴로 형성됨에 따라 접속패드(14) 상부와 부분 중첩되면서 전기적 접속이 이루어지며, 패드결합요홈(16)입구에서는 연결단자핀(13)이 도전부가 형성되지 않은 회로기판과 접속되면서 패드결합요홈(16)입구에 삽입되게 되어 연결단자핀(13)의 탄성력과 패드결합요홈(16)의 양측에 도전체에 의하여 형성된 걸림턱에 의하여 컨넥터와 접속패드는 전기적 결합과 기계적 결합이 이루어져 회로기판과 컨넥터간의 접속시 별도의 납땜공정이 불필요하고 접속에 따른 제품의 크기를 최소화할 수 있는 접속패드와의 중심불일치에 따른 불량을 감소시킬 수 있다.That is, the end of the connection terminal pin 13 is overlapped with the upper part of the connection pad 14 as the pad coupling groove 16 is formed in a trapezoidal shape to make an electrical connection, and at the inlet of the pad coupling groove 16, the connection terminal is provided. The pin 13 is inserted into the pad coupling groove 16 inlet while being connected to a circuit board on which the conductive part is not formed, and the elastic force of the connection terminal pin 13 and the engagement formed by the conductors on both sides of the pad coupling groove 16. The connector and the connection pad are made of electrical coupling and mechanical coupling by the jaw, so there is no need for a separate soldering process when connecting between the circuit board and the connector, and defects due to mismatch between the connection pads can be minimized. Can be reduced.
본 발명은 구체적으로 설명하지는 않았으나 패드결합요홈(16)의 사다리꼴높이(도 5b에서 h로 표시)는 단자핀(13)의 길이와 동일하거나 적게하여 접촉부위를 증가시킬 수 있음은 본 분야의 당업자라면 당연히 예측할 수 있고, 컨넥터와 회로기판의 결합시 결합의 편의를 위하여 도 3 및 도 5a에 도시된 바와 같이 접속패드가 설치된 회로기판의 양 측면에 단차(17)를 형성하여 접속패드부가 형성된 회로기판부의 폭이 컨넥터 케이스내부 폭보다 적게 함으로서 연결단자핀(13)이 형성된 커넥터 케이스(11) 내부에 결합하게 할 수 있는 것은 본 분야의 한 응용 예로서 본 발명의 범주에 포함됨은 자명한 사실이다.Although the present invention is not described in detail, the trapezoidal height of the pad coupling groove 16 (indicated by h in FIG. 5B) may be increased by the same or smaller length of the terminal pin 13 so as to increase the contact area. If it can be predicted, of course, for the convenience of coupling when the connector and the circuit board, as shown in Figs. 3 and 5a to form a step 17 on both sides of the circuit board is provided with a connection pad to form a connection pad portion It is obvious that the width of the substrate portion is smaller than the inner width of the connector case so that the connection terminal pin 13 can be coupled to the inside of the connector case 11 in which the connection terminal pin 13 is formed. .
이상에서와 같이 본 발명에 따르면 회로기판과 컨넥터가 부착되어 있는 전자부품을 바로 연결시킴으로서 회로기판으로부터 전기적신호를 입출력하기 위하여 컨넥터를 회로기판과 결합하는 전자부품을 소형화할 수 있고, 납땜에 따른 공정이 불필요하게 되어 생산원가절감 및 획기적인 불량감소 등 제품의 신뢰성 향상에 기여한다.As described above, according to the present invention, by directly connecting the circuit board and the electronic component to which the connector is attached, it is possible to miniaturize the electronic component that couples the connector to the circuit board in order to input and output electrical signals from the circuit board. This becomes unnecessary, contributing to improving the reliability of the product, such as reducing production cost and drastically reducing defects.
또한, 컨넥터 케이스의 크기나 구조가 각 제조사별로 다른 규격을 사용하므로 그 부위에 연결이 되는 컨넥터는 세트된 전용규격을 사용해야 케이스외형에 의해 접촉점의 중심이 맞게 되어 있으나, 본 제품은 연결요홈에 의하여 각기 연결핀이 각기 독립된 중심점을 ??아 연결되어, 컨넥터의 외형에 영향을 받지 않음으로패드가 형성된 회로기판의 폭을 기존의 컨넥터의 내부폭의 크기를 기존의 컨넥터 중에서 최소 크기에 맞게 하면 어느 회사제품이든 케이스외형에 관계없이 접촉 중심의 연결이 가능하여 다수의 각기 다른 제품의 컨넥터와 연결될 수 있다.In addition, since the size and structure of the connector case use different specifications for each manufacturer, the connector connected to the part should use the set dedicated standard, but the center of the contact point is made by the case shape. Since the connecting pins are connected to each other through independent center points, they are not affected by the external shape of the connector.If the width of the pad-formed circuit board is adjusted to the minimum size among the existing connectors, Whether it is a company product or a case, the contact center connection is possible, so it can be connected to the connector of many different products.
본 발명의 실시예에 나타난 구성을 컴퓨터의 저장장치로 사용되는 하드디스크에 적용할 경우 연결단자핀의 길이 만큼(본 분야에서 관용적으로 사용되는 10~20 Gbyte의 하드디스크의 경우 5mm 정도) 축소되며 연결핀이 50개인 경우에는 50개소에서 발생 할 수 있는 불량개소를 줄일 수 있어 제품의 신뢰성이 향상되고 생산공정의 감소로 제품생산원가를 낮추어 경쟁력을 제고시킬 수 있고 다수의 회사에서 생산되는 하드디스크를 마음대로 선택 사용할 수 있다.When the configuration shown in the embodiment of the present invention is applied to a hard disk used as a storage device of a computer, it is reduced by the length of the connection terminal pin (about 5 mm in the case of a 10-20 Gbyte hard disk conventionally used in the field). In the case of 50 connecting pins, it is possible to reduce the defects that can occur at 50 places, which improves the reliability of the product and reduces the production cost, thereby improving the competitiveness by lowering the production cost, and hard disks produced by many companies. Can be used at will.
