상기와 같은 목적은, 각종 전기 및 전자 부품들이 탑재되며, 다른 전기 부품과의 전기적인 접속을 위한 다수의 접속핀을 가진 단자부가 마련되어 있는 인쇄회로기판 조립체의 고정 구조에 있어서, 상기 단자부의 접속핀이 억지 끼워맞춤되고, 상기 단자부의 접속핀과 대향하는 방향에서 다른 전기 부품에 연결된 전선의 접속핀이 억지 끼워맞춤되며, 상호 통전 가능하게 연결하는 연결 부재를 구비하는 인쇄회로기판 조립체의 고정 구조에 의해 달성된다.The purpose of the above, in the fixed structure of the printed circuit board assembly is equipped with a terminal portion having a plurality of connection pins for mounting electrical and electronic components, and electrical connection with other electrical components, the connection pin of the terminal portion The interference fit, the connection pins of the electric wires connected to the other electrical components in the direction opposite to the connection pins of the terminal portion, the interference fit, and the fixing structure of the printed circuit board assembly having a connection member for connecting with each other. Is achieved.

이 연결 부재에는 단자부의 접속핀이 억지 끼워맞춤되는 일측에서 전선의 접속핀이 억지 끼워맞춤되는 타측까지 관통하는 다수의 접속구가 일체로 형성되어 있고, 그 접속구의 중심선에 대하여 수직방향의 외주면 상에 걸림턱이 형성되어 있다.The connecting member is integrally formed with a plurality of connecting holes penetrating from one side to which the connecting pin of the terminal part is press-fitted to the other side to which the connecting pin of the wire is press-fitted, on the outer circumferential surface perpendicular to the center line of the connecting port. A locking jaw is formed.

이하, 첨부된 도면을 참조하여 본 고안의 바람직한 실시예를 보다 상세하게설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

본 고안의 바람직한 실시예를 도시한 도 2를 참조하면, 인쇄회로기판 조립체(1)의 상면에는 각종 전자 및 전기 부품이 탑재되어 있으며, 그 하면의 일측에는 단자부가 마련되어 있다. 이 단자부에는 다수의 접속핀(5)이 일정 간격으로 밀집되어 있다. 이 접속핀(5)은 후술할 잭(20)에 꽂혀진다.Referring to FIG. 2, which shows a preferred embodiment of the present invention, various electronic and electrical components are mounted on an upper surface of a printed circuit board assembly 1, and a terminal part is provided on one side of the lower surface thereof. In this terminal portion, a plurality of connecting pins 5 are concentrated at regular intervals. This connecting pin 5 is plugged into the jack 20 which will be described later.

인쇄회로기판 조립체(1)의 하면과 소정거리를 두고 통전용 잭(20)이 배치되어 있다. 이 잭(20)은 인쇄회로기판 조립체(1)의 단자부의 접속핀(5)과 상호 접속되며, 본체(2)의 일부에 억지 끼워맞춤되어 외부의 충격에 의한 자발적인 이탈이 불가능하게 되어 있다. 이러한 자발적인 이탈을 방지하기 위해 잭(20)의 외주면에는 걸림턱(7;7')이 나란하게 상하로 형성되어 있다.The power supply jack 20 is disposed at a predetermined distance from the lower surface of the printed circuit board assembly 1. The jack 20 is interconnected with the connecting pins 5 of the terminal portion of the printed circuit board assembly 1, and is forcibly fitted to a part of the main body 2 so that spontaneous detachment due to external impact is impossible. In order to prevent such spontaneous departure, the locking jaw (7; 7 ') is formed in the upper and lower side by side on the outer peripheral surface of the jack (20).

이들 걸림턱중 하나(7))는 상방향에서 가해지는 가압력을 충분히 버틸 수 있도록 큰 치수로 되어 있고, 대향하는 다른 하나(7')는 자발적인 이탈을 방지하도록 작은 치수로 되어 있다. 세부적으로 언급하면, 인쇄회로기판 조립체(1)는 본체(2)에 마련된 잭(20)을 향하여 가압되고, 이때 인쇄회로기판 조립체(1)의 단자부의 접속핀(5)이 잭(20)의 접속구((6) 속으로 억지 끼워맞춤된다. 따라서, 이러한 가압력에 의해 잭(20)이 본체(2)에 충분히 지지될 수 있도록, 잭(20)의 외주면에 형성되어 있는 큰 치수의 걸림턱(7)에 의해 잭(20)이 본체(2)의 하방향으로 이탈되는 것을 방지한다. 다른 한편, 인쇄회로기판 조립체(1)가 잭(20)과 결합된 후에 외부의 충격에 의해 본체(2)로부터 상방향으로 이탈되는 것을 방지하도록, 그리고 교체 및 수리를 위해 강한 외력에 의해 본체(2)로부터 분리될 수 있도록, 작은 치수의걸림턱(7')이 잭(20)의 외주면에 형성되어 있다.One of these latching jaws 7 is of large size to sufficiently withstand the pressing force exerted in the upward direction, and the other of the opposing ones 7 'is of small size to prevent spontaneous release. Specifically, the printed circuit board assembly 1 is pressed toward the jack 20 provided in the main body 2, whereby the connecting pin 5 of the terminal portion of the printed circuit board assembly 1 is connected to the jack 20. It is forcibly fitted into the connection port 6. Therefore, the large-sized locking jaw formed in the outer circumferential surface of the jack 20 so that the jack 20 can be fully supported by the main body 2 by this pressing force. 7) prevents the jack 20 from being disengaged in the downward direction of the main body 2. On the other hand, after the printed circuit board assembly 1 is engaged with the jack 20, the main body 2 is caused by an external impact. In order to prevent upward departure from the main body 2 and to be separated from the main body 2 by a strong external force for replacement and repair, a small-sized locking jaw 7 'is formed on the outer peripheral surface of the jack 20. have.

잭(20)에는 상방향에서 하방향으로 억지 끼워맞춤되는 인쇄회로기판 조립체(1)의 단자부의 접속핀(5)과 하방향에서 상방향으로 억지 끼워맞춤되는 전선의 접속핀(5')을 위한 다수의 접속구(6)가 형성되어 있다. 이 접속구(6)는 접속핀(5;5')이 끼워져서 쉽게 빠지는 것을 방지하기 위해 그 내주면에 중심선 방향을 따라 다수의 마찰용 띠(6)가 형성되어 있다. 접속구(6)는 인쇄회로기판 조립체(1)의 단자부의 접속핀(5)의 길이와 전선의 접속핀(5')의 길이를 모두 합한 길이 보다 적어도 동일하거나 더 길다.The jack 20 has connection pins 5 'of the terminal portion of the printed circuit board assembly 1 forcibly fitted from the upper direction to the downward direction and connecting pins 5' of the wires that are forcibly fitted upward from the downward direction. Many connection ports 6 are formed. In order to prevent the connecting pins 5 and 5 'from being easily pulled out by the connecting holes 6, a plurality of friction bands 6 are formed on the inner circumferential surface thereof in the center line direction. The connector 6 is at least equal to or longer than the length of both the length of the connecting pin 5 of the terminal portion of the printed circuit board assembly 1 and the length of the connecting pin 5 'of the electric wire.

한편, 인쇄회로기판 조립체(1)가 상방향에서 하방향으로의 가압력에 의해 잭(20)에 결합될 때, 인쇄회로기판 조립체(1)의 단자부의 접속핀(5)이 잭(20)에 완전히 억지 끼워맞춤이 된 후에도 계속하여 가압됨에 따라 본체(2)로부터 잭(20)이 분리되는 것을 방지하기 위해, 본체(2)로부터 상향으로 연장된 리브(12)에는 계단면(9)이 형성되어 있다. 또한, 인쇄회로기판 조립체(1)가 잭(20)에 완전 결합된 후에 충격에 의해 분리되는 것을 방지하기 위해, 본체의 리브(12)의 상부에 훅 부재(15)가 형성되어 있다. 이 훅 부재(15)는 소정의 탄성을 보유하고 있으며, 이에 따라 인쇄회로기판 조립체(1)의 교체 및 수리시 강한 외력에 의해 훅 부재(15)는 인쇄회로기판 조립체(1)와의 걸림이 해제될 수 있다.On the other hand, when the printed circuit board assembly 1 is coupled to the jack 20 by the pressing force from the upward direction to the downward direction, the connecting pin 5 of the terminal portion of the printed circuit board assembly 1 is connected to the jack 20. A stepped surface 9 is formed in the rib 12 extending upward from the main body 2 to prevent the jack 20 from being separated from the main body 2 as it continues to be pressurized even after the complete interference fit. It is. In addition, the hook member 15 is formed on the upper portion of the rib 12 of the main body in order to prevent the printed circuit board assembly 1 from being separated by the impact after being fully coupled to the jack 20. The hook member 15 has a predetermined elasticity, and accordingly, the hook member 15 is released from the printed circuit board assembly 1 due to a strong external force during the replacement and repair of the printed circuit board assembly 1. Can be.

이하 인쇄회로기판 조립체(1)을 본체(2)에 조립하는 과정을 살펴보면, 사출성형법에 의해 제조된 본체(2)에 잭(20)이 억지 끼워맞추고 나서, 이 잭(20)의 하측에서 전선의 접속핀(5')이 잭(20)의 접속구(6)에 억지끼워맞춰진다. 다음에, 인쇄회로기판 조립체(1)를 잭(20)의 상측에서 잭(20)의 접속구(6)에 억지끼워맞춰진다. 이때, 별도의 체결수단을 이용하지 않더라도, 잭(20)의 접속구(6)와 이 접속구(6)에 억지끼워맞춰진 인쇄회로기판 조립체(1)의 단자부의 접속핀(5)과의 마찰 결합력에 의해, 인쇄회로기판 조립체(1)가 외부 충격에 의해서도 잭(20)으로부터 쉽게 분리되지 않는다.In the following, the process of assembling the printed circuit board assembly 1 to the main body 2 will be described. After the jack 20 is forcibly fitted to the main body 2 manufactured by the injection molding method, an electric wire is provided under the jack 20. Is connected to the connector 6 of the jack 20. Next, the printed circuit board assembly 1 is fitted to the connector 6 of the jack 20 on the upper side of the jack 20. At this time, even if a separate fastening means is not used, the frictional coupling force between the connection port 6 of the jack 20 and the connection pin 5 of the terminal portion of the printed circuit board assembly 1 fitted into the connection port 6 is prevented. As a result, the printed circuit board assembly 1 is not easily separated from the jack 20 even by an external impact.

상기된 바와 같은 본 고안에 따르면, 잭을 통하여 단자부 접속핀과 다른 전기부품에 연결된 전선의 접속핀이 일체로 용이하게 결합될 수 있어서 인쇄회로기판의 조립이 용이하다.According to the present invention as described above, the connection pin of the wire connected to the terminal connection pin and other electrical components through the jack can be easily combined integrally, so that the assembly of the printed circuit board is easy.
