Description

접지 기능을 구비하는 ＦＰＣ/ＦＦＣ용 커넥터{CONNECTOR FOR FPC/FFC}FPC / FFC connector having a grounding function {CONNECTOR FOR FPC / FFC}

본 발명은 FPC 또는 FFC 결합용 커넥터 및 이에 사용되는 FPC, FFC에 관한 것으로서, 보다 상세하게는 FPC 또는 FFC를 결합하기 위한 걸림터미널에 있어서 돌출되는 접지 구성을 구비함으로써, 걸림터미널이 록킹 기능을 할 뿐만 아니라 접지 기능까지도 할 수 있도록 하기 위한 커넥터와 플렉시블 케이블에 관한 것이다.
The present invention relates to a connector for connecting an FPC or an FFC and an FPC or FFC used therefor. More particularly, the present invention provides a grounding structure that protrudes from a latching terminal for coupling an FPC or an FFC, The present invention also relates to a connector and a flexible cable for providing a grounding function.

본 발명은 플렉시블 케이블 커넥터에 관한 것으로서, 보다 상세하게는 결합 상태를 견고하게 보강하면서도 접지 성능, 기능을 추가한 플렉시블 케이블 커넥터에 관한 것이다. 일반적으로 플렉시블 케이블은 FPC(Flexible Printed Circuit), FFC(Flexible Flat Cable)로 구분되는 얇은 필름 형태의 케이블인데, 복잡한 회로를 유연한 절연 필름 위에 형성한 연성 인쇄 회로 내지는 케이블로서 휨, 겹침, 접힘, 말림, 꼬임 등의 유연성 때문에 각종 전자제품에 널리 사용되고 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible cable connector, and more particularly, to a flexible cable connector to which a grounding performance and a function are added while firmly reinforcing a coupled state. Generally, a flexible cable is a thin film type cable divided into an FPC (Flexible Printed Circuit) and an FFC (Flexible Flat Cable). A flexible printed circuit or a cable having a complex circuit formed on a flexible insulation film is used as a flexible printed circuit or a cable. Because of its flexibility, such as twisting, it is widely used in various electronic products.

이러한 플렉시블 케이블을 인쇄회로기판에 전기적으로 접속하기 위하여, 인쇄회로기판에는 플렉시블 케이블 커넥터가 장착된다.
In order to electrically connect such a flexible cable to a printed circuit board, a flexible cable connector is mounted on the printed circuit board.

도 1은 일반적인 커넥터의 외관을 나타내는 도면이다. 도 1을 참조하면, 베이스(10)에는 다수의 터미널(30)이 일렬로 배치되고, 케이블이 접속되는 방향으로는 액츄에이터(20)가 회동되며 가압할 수 있도록 구비된다.1 is a view showing the appearance of a general connector. Referring to FIG. 1, a plurality of terminals 30 are arranged in a row on a base 10, and an actuator 20 is pivoted and pressurized in a direction in which cables are connected.

커넥터에 결합된 FPC(미도시) 등의 플렉시블 케이블은 터미널 사이의 밀착 압력에 의해 구속되기 때문에 쉽게 빠지는 문제점이 있고, 이를 보완하기 위해 액츄에이터(20)를 도입하여 회동에 따른 압착력으로 결합된 FPC 접속단이 커넥터에 구속되도록 한 것이다.A flexible cable such as an FPC (not shown) coupled to the connector is easily restrained because it is restrained by the close contact pressure between the terminals. In order to compensate for this problem, the actuator 20 is inserted, And the end is constrained to the connector.

그런데 이러한 액츄에이터(20)의 회동 체결 이전에 케이블에 외측 방향의 힘이 가해지거나, 또는 액츄에이터(20)의 압착력보다 큰 힘이 작용되는 경우에는 여전히 쉽게 빠질 수밖에 없는 문제가 있다.However, there is a problem that when the actuator 20 is subjected to a force exerted in the outward direction before the rotation of the actuator 20, or when a force larger than the force of the actuator 20 is applied, the actuator 20 can not be easily removed.

따라서 상기와 같이 FPC 접속단과 커넥터가 일정한 압력에 의해 쉽게 빠지는 구성은 안전성을 요하는 정밀 기계나 장치에 적용할 수 없는 문제는 물론이고, 특히 FPC의 접속단이 조금만 빠지더라도 회로가 차단되는 정교하고 미세한 기계나 장치에는 적용할 수 없으므로 상기 FPC의 접속단과 커넥터의 상호 결합에 대해 더욱 정확한 구속력이 요구되고 있다.Therefore, the configuration in which the FPC connection end and the connector are easily removed by a certain pressure as described above can not be applied to a precision machine or an apparatus requiring safety, and in particular, a problem that the circuit is cut off It can not be applied to a fine machine or a device, and therefore, a more accurate binding force is required for the mutual coupling of the connector and the connector of the FPC.

따라서 커넥터에는 케이블을 걸어 결합시키기 위한 걸림터미널을 구비하고, 케이블에는 이에 맞물리는 걸림홈을 형성함으로써, 케이블을 삽입하기만 하더라도 1차적인 고정이 가능하고, 최종 체결 후에는 쉽게 이탈을 방지하도록 하는 것이 바람직한데, 이러한 걸림터미널은 결합의 기능 외에는 다른 기능을 수행하지 않고 있다.
Thus, the connector is provided with a latching terminal for latching the cable, and the cable is provided with a latching groove which engages with the cable, so that the cable can be fixed only once, and after the final fastening, , Which does not perform any other function than the function of the engagement.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

도 2는 본 발명의 터미널들을 나타내는 도면이다. 도 2를 참조하면, (a)는 제1터미널(30), (b)는 제2터미널(40), (c)는 걸림터미널(50)을 나타내는 것이고, 대부분 H 와 같은 형상을 기본 구조로 포함하고 있다.2 is a diagram showing terminals of the present invention. Referring to FIG. 2, (a) shows a first terminal 30, (b) shows a second terminal 40, (c) shows a latching terminal 50, .

제1터미널(30), 제2터미널(40)은 교대로 상호간의 사이사이에 배치되며, 내측으로 FFC, FPC 등의 플렉시블 케이블(100)을 수용하며 상하방으로 접속하게 된다. 제1,2터미널(30, 40)이 집적된 양 측방 단부에는 걸림터미널(50)이 각각 배치되는데, 걸림터미널(50)은 상부연장부(51), 연결부(53), 하부연장부(52)를 기본 구조로 구성되고, 상부연장부(51) 또는 하부연장부(52)의 단부에는 사이 공간으로 돌출되는 돌출부(54)를 구비한다. 한편, 연결부(53)와 돌출부(54)의 사이에는 상부연장부(51) 또는 하부연장부(52)로부터 사이 공간으로 돌출되는 돌출접촉부(55)가 구비된다.
The first terminal 30 and the second terminal 40 are alternately arranged between each other, and the flexible cable 100 such as an FFC or an FPC is accommodated inwardly and connected to the upper and lower sides. A latching terminal 50 is disposed at both side ends of the first and second terminals 30 and 40. The latching terminal 50 includes an upper extension portion 51, a connection portion 53, a lower extension portion 52 And an end portion of the upper extension portion 51 or the lower extension portion 52 is provided with a protrusion 54 projecting into the space. A protrusion contacting portion 55 protruding from the upper extending portion 51 or the lower extending portion 52 is provided between the connecting portion 53 and the protruding portion 54.

도 3은 본 발명의 커넥터와 플렉시블 케이블이 결합되기 전의 상태를 나타내는 도면이다. 도 3을 참조하면, 커넥터의 베이스(10)에는 제1,2터미널(30, 40)이 교차로 배치되어 결합되고, 양 측단에는 걸림터미널(50)이 각각 1개씩 배치되어 있다.3 is a view showing a state before the connector of the present invention and the flexible cable are coupled. Referring to FIG. 3, the first and second terminals 30 and 40 are arranged in an alternating manner on the base 10 of the connector, and one of the engagement terminals 50 is disposed on each of the opposite ends.

플렉시블 케이블(100)에는 제1,2터미널(30, 40)과 접촉하기 위한 도체 부분인 제1단자(130), 제2단자(140)가 장형으로 형성되어 있으며, 본체(110) 필름의 양 측방으로는 내입된 홈 형태의 걸림홈(120)이 형성되어 있다.The flexible cable 100 has a first terminal 130 and a second terminal 140 which are conductive portions for contacting the first and second terminals 30 and 40. The flexible cable 100 has a length And an engaging groove 120 in the form of an inward groove is formed laterally.

At this time, since the engaging terminal 50 is not in contact with or connected to the conductor terminal of the flexible cable 100 at all, it does not perform any other function except for holding the engaging groove 120.

도 5는 본 발명의 걸림터미널과 플렉시블 케이블의 결합 상태를 나타내는 도면이다. 도 5를 참조하면, 걸림터미널(50)의 상방연장부(51)의 연결부(53)와 돌출부(54) 사이 공간에는 하방으로 돌출되는 돌출접촉부(55)를 구비한다.Fig. 5 is a view showing the engagement state of the engagement terminal and the flexible cable according to the present invention. Referring to FIG. 5, a protruding contact portion 55 protruding downward is formed in a space between the connection portion 53 and the protruding portion 54 of the upwardly extending portion 51 of the latching terminal 50.

이러한 돌출접촉부(55)는 상방연장부(51)로부터 필요한 길이만큼 돌출됨으로써, 그 하방에 삽입되는 플렉시블 케이블(100)의 도체 단자와 접촉될 수 있도록 한다.The projected contact portion 55 protrudes from the upwardly extending portion 51 by a required length so as to be brought into contact with the conductor terminal of the flexible cable 100 inserted below the projected contact portion 55. [

플렉시블 케이블(100)에는 별도의 그라운드단자(150)를 형성하되, 그라운드단자(150)는 플렉시블 케이블(100)이 커넥터에 삽입될 때, 걸림터미널(50)이 위치되는 양단부측을 상하로 마주볼 수 있도록 하는 위치에 구비된다. 따라서 플렉시블 케이블(100)이 커넥터에 삽입되면, 걸림터미널(50)의 돌출부(54)가 먼저 접촉되기 시작하고, 돌출부(54)가 걸림홈(120)에 내입되면서 하강하면, 상방연장부(51)가 하강하면서 돌출접촉부(55)도 하방 이동되면서 그라운드단자(150)에 접촉된다.The ground terminal 150 is formed on the flexible cable 100 so that the ground terminal 150 faces the opposite ends of the flexible terminal 100 in the vertical direction when the flexible cable 100 is inserted into the connector. And the like. Therefore, when the flexible cable 100 is inserted into the connector, the protruding portion 54 of the locking terminal 50 starts to contact first, and when the protruding portion 54 is lowered while being inserted into the locking groove 120, The protruding contact portion 55 is also moved downward and is brought into contact with the ground terminal 150.

걸림터미널(50)은 회로기판의 접지측에 접속됨으로써, 그라운드단자(150)를 접지시키고, 이에 노이즈를 제거하는 기능을 수행할 수 있게 된다.
The latching terminal 50 is connected to the ground side of the circuit board, thereby grounding the ground terminal 150, thereby performing a function of removing noise.

도 6은 일반적인 플렉시블 케이블을 나타내는 도면이고, 도 7은 본 발명의 플렉시블 케이블을 나타내는 도면이다. 도 6을 참조하면, FFC, FPC 등의 플렉시블 케이블(100)은 필름형 본체(110)에 제1단자(130), 제2단자(140)가 교대로 나란히 배치되어, 각각 터미널들에 접속되도록 구성된다.Fig. 6 shows a general flexible cable, and Fig. 7 shows a flexible cable according to the present invention. Referring to FIG. 6, a flexible cable 100 such as an FFC or an FPC has a first terminal 130 and a second terminal 140 which are alternately arranged side by side in a film-type body 110 so as to be connected to terminals .

도 7을 참조하면, 제1,2단자(130,140)의 외측으로 그라운드단자(150)가 배치된다. 그라운드단자(150)는 걸림홈(120)의 선단측, 즉 도면상의 확대 원형 부분 기준으로는 걸림홈(120)의 좌측부분에까지 연장되어 접지접촉부(152)를 형성하여야 한다. 즉 걸림홈(120)의 내입 너비 A에는 돌출부(54)가 위치될 때, 접지접촉부(152)는 B와 같은 너비의 전부 또는 일부 걸치도록 형성됨으로써, 동일 선상에 위치되는 돌출접촉부(55)와 접속이 가능하게 된다.
Referring to FIG. 7, a ground terminal 150 is disposed outside the first and second terminals 130 and 140.
