Description

커넥터{Connector}Connector {Connector}

본 발명은 플렉시블 케이블을 접속하기 위한 커넥터에 관한 것으로, 보다 상세하게는 플렉시블 케이블의 접속부의 이물을 제거할 수 있으며, 접촉 신뢰성을 높일 수 있는 커넥터에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting a flexible cable, and more particularly, to a connector capable of removing foreign substances from a connecting portion of a flexible cable and improving contact reliability.

플렉시블 케이블을 접속하기 위한 커넥터는, 플렉시블 케이블을 커넥터에 삽입할 때 삽입저항력이 아예 없는 무삽입력 커넥터와, 약간의 삽입저항력이 있는 저삽입력 커넥터로 구분할 수 있다.
The connector for connecting the flexible cable can be divided into a non-insertion input connector having no insertion resistance at all when the flexible cable is inserted into the connector, and a low insertion input connector having a slight insertion resistance.

무삽입력 커넥터는 대한민국 등록특허 10-1012619호에 개시된 것을 그 일례로 들 수 있는데, 도 1에 도시된 바와 같이 하우징(10)과, 접속단자(20)의 회전지지부(21)를 중심으로 회전가능한 가압부재(30)를 구비하고 있다. 이와 같은 커넥터는 가압부재(30)와 접속단자(20)의 접촉부(22) 사이에 플렉시블 케이블을 삽입한 후 가압부재(30)를 회전시켜 가압부재(30)의 가압면(31)이 플렉시블 케이블의 상면을 하방으로 누르면 플렉시블 케이블의 접속부와 접속단자(20)의 접촉부(22)가 서로 접촉을 유지할 수 있게 된다. The non-insertable input connector may be one disclosed in Korean Patent Registration No. 10-1012619. As shown in FIG. 1, the non-insertable input connector rotates around the housing 10 and the rotation support part 21 of the connection terminal 20. The pressing member 30 is provided as much as possible. Such a connector inserts a flexible cable between the pressing member 30 and the contact portion 22 of the connecting terminal 20 and rotates the pressing member 30 so that the pressing surface 31 of the pressing member 30 is a flexible cable. When pressing the upper surface of the lower side of the flexible cable connection portion and the contact portion 22 of the connection terminal 20 can be maintained in contact with each other.

상기 종래 기술의 무삽입력 커넥터는 가압부재(30)의 가압면(31)과 접속단자(20)의 접촉부(22) 사이의 거리 및 가압부재의 강성 등을 조절함에 따라 충분한 접촉력을 얻을 수 있는 반면, 접속단자(20)의 접촉부(22)와 접촉하는 플렉시블 케이블의 접속부가 산화 또는 이물에 의해 오염되는 경우 접촉 신뢰성이 극히 낮아지는 문제점이 있었다.
The conventional insertless input connector can obtain a sufficient contact force by adjusting the distance between the pressing surface 31 of the pressing member 30 and the contact portion 22 of the connecting terminal 20 and the rigidity of the pressing member. On the other hand, when the connection portion of the flexible cable contacting the contact portion 22 of the connection terminal 20 is contaminated by oxidation or foreign matter, the contact reliability is extremely low.

저삽입력 커넥터는 대한민국 등록특허 10-1138124호에 개시된 것을 그 일례로 들 수 있는데, 도 2에 도시된 바와 같이 플렉시블 케이블을 하우징에 유지된 가압단자(40)의 가압부(42)와 접속단자(20)의 접촉부(22) 사이 간극으로 끼워 넣게 된다. 이때 플렉시블 케이블의 접속부는 접촉부(22)와 슬라이딩 접촉을 이루면서 오염을 제거할 수는 있지만, 통상 이와 같은 저삽입력 커넥터의 접속단자는 판재를 굽힘가공하여 제작하므로 슬라이딩 면적이 넓고 이에 따라 오염에 더 취약한 문제점이 있다. 그리고 접촉력이 가압부(42)와 접촉부(22) 사이의 간극 및 가압단자(40)와 접속단자(20)의 강성에 좌우될 뿐만 아니라, 삽입을 용이하게 하려면 접촉력이 낮아지고 접촉력을 높이려면 삽입이 어려워지는 문제점이 있었다.
The low insertion force connector may be an example of what is disclosed in Korean Patent No. 10-1138124. As shown in FIG. 2, the pressing portion 42 and the connection terminal of the pressing terminal 40 holding the flexible cable in the housing are illustrated. The gap between the contact portions 22 of the 20 is inserted. At this time, the connection portion of the flexible cable can remove the contamination while making sliding contact with the contact portion 22, but the connection terminal of such a low insertion force connector is usually manufactured by bending the plate material, so the sliding area is wider and consequently more contaminated. There is a vulnerability. In addition, the contact force depends not only on the clearance between the pressing portion 42 and the contact portion 22 and the rigidity of the pressing terminal 40 and the connecting terminal 20, but also the contact force is lowered to facilitate the insertion, and the insertion force is increased to increase the contact force. There was a problem that became difficult.

The lower arm 210 is deformed toward the lower side because the pressing member is formed to have a longer distance from the rotary support 21 to the upper surface of the flexible cable, the contact portion 22 is the flexible cable by the elastic force according to this deformation. The contact force is formed by pressing (1) upward. At this time, the support portion 405 of the pressing member 30 is spaced apart from the pressing member supporting surface 101 of the housing 10.

도 7(b) 및 도 8(b)의 상태에서 가압부재(30)를 화살표 방향으로, 즉 작동부(403)를 눌러 하우징의 후방을 향해 밀게 되면, 가압부재(30)의 회전축부(401)는 상부 아암(200)의 슬라이딩 지지부(23)와 슬라이딩 접촉을 일으키게 된다. 이때, 도 7(c) 및 도 8(c)와 같이 가압부재(30)는 하측으로 향해 좀 더 이동되며, 이러한 이동량은 회전지지부(21)보다 낮은 위치에 형성된 슬라이딩 지지부(23)에 의해서 유도된다. 이때, 가압부재(30)의 지지부(405)는 하우징(10)의 가압부재 지지면(101)과 슬라이딩 접촉을 이루게 된다. 이러한 슬라이딩 접촉을 이루면 가압면 위치가 낮아지는 것을 방지할 수도 있어 바람직하지만, 플렉시블 케이블은 가압부재와 하부 아암의 접촉부 사이에서 유지되고 있으므로, 반드시 슬라이딩 접촉을 이루어야만 본 발명의 목적을 달성할 수 있는 것은 아니다.
7 (b) and 8 (b), when the pressing member 30 is pushed toward the rear of the housing in the direction of the arrow, that is, by pressing the operating portion 403, the rotating shaft portion 401 of the pressing member 30 is pressed. ) Causes sliding contact with the sliding support 23 of the upper arm 200. At this time, as shown in Fig. 7 (c) and 8 (c) the pressure member 30 is moved further toward the lower side, this movement amount is guided by the sliding support 23 formed in a lower position than the rotation support 21 do. At this time, the support 405 of the pressing member 30 is in sliding contact with the pressing member supporting surface 101 of the housing 10. The sliding contact may be prevented from lowering the position of the pressing surface. However, since the flexible cable is held between the contact portion of the pressing member and the lower arm, the sliding contact must be made to achieve the object of the present invention. It is not.

하우징(10)의 후방을 향해 밀려 들어가는 가압부재(30)는 도 7(c)와 같이 하우징 후벽(12)에 닿게 되면 더 이상 밀려 들어가지 않게 되어 최종결합위치에 도달하게 된다.
When the pressing member 30 pushed toward the rear of the housing 10 touches the rear wall 12 of the housing as shown in FIG. 7 (c), the pressing member 30 is no longer pushed in to reach the final coupling position.

플렉시블 케이블(1)의 걸림부(2a)는 가압부재(30)의 체결부(404)와 결합되어 있으므로, 가압부재(30)을 하우징 후방으로 밀게 되면, 플렉시블 케이블 역시 하우징 후방으로 밀려 들어가게 된다.
Since the locking portion 2a of the flexible cable 1 is coupled with the fastening portion 404 of the pressing member 30, when the pressing member 30 is pushed to the rear of the housing, the flexible cable is also pushed to the rear of the housing.

이에 따라, 접속단자(20)의 접촉부(22)와 접속되어 있는 플렉시블 케이블 하면의 접속부는 접촉부(22)에 의해 그 표면이 긁혀지면서 표면의 오염물이 제거되어 접촉 신뢰성이 높아지게 된다.
As a result, the contact portion of the lower surface of the flexible cable connected to the contact portion 22 of the connection terminal 20 is scratched by the contact portion 22, and contaminants on the surface are removed, thereby increasing contact reliability.

본 실시예에서는 가압부재(30)를 하우징 후방으로 밀어 넣을 때, 회전지지부(21)에 비해 낮은 위치에 형성된 슬라이딩 지지부(23)에 의해 가압부재(30)가 하측으로 좀 더 이동되므로 접촉부(22)와 플렉시블 케이블의 접속부와의 접촉력이 더 높아지게 된다. In the present embodiment, when the pressing member 30 is pushed to the rear of the housing, the pressing member 30 is moved further downward by the sliding support 23 formed at a lower position than the rotation supporting portion 21, so that the contact portion 22 ) And the contact between the flexible cable connection becomes higher.

그러나, 회전지지부(21)와 슬라이딩 지지부(23)의 높이가 같더라도, 도 7(b)와 같이 가압부재의 회전을 완료한 상태에서 접촉부(22)와 플렉시블 케이블의 접속부와의 접촉력이 충분히 유지될 수 있는 경우에는 슬라이딩 지지부(23)의 위치가 회전운동지지부(21)의 위치보다 낮을 필요는 없다.
However, even if the height of the rotation support part 21 and the sliding support part 23 is the same, the contact force between the contact part 22 and the connection part of a flexible cable is fully maintained in the state which completed rotation of a pressing member like FIG.7 (b). If possible, the position of the sliding support 23 need not be lower than the position of the rotary motion support 21.

또한, 가압부재(30)를 가압방향으로 회전시킨 후 하우징 후방으로 밀어 가압부재가 최종결합위치에 도달하기 전까지, 상기 회전축부(401)와 분리벽(402)과 작동부(403) 사이의 통공(406)은 상기 상부 아암(200)의 선단이 작동부(403)의 후벽(407)과 맞닿지 않는 크기를 가져야만 가압부재(30)가 도 7 및 도 8과 같이 작동하게 되는 것이다.
In addition, after the pressing member 30 is rotated in the pressing direction and pushed toward the rear of the housing until the pressing member reaches the final engagement position, the hole between the rotating shaft portion 401, the separation wall 402 and the operating portion 403 The pressure member 30 operates as shown in FIGS. 7 and 8 only when the tip of the upper arm 200 has a size that does not contact the rear wall 407 of the operation unit 403.
