예컨대, 첨부 도면 중, 도 1a는 종래의 평면 케이블용 하우징 컨넥터의 구조를 보여주는 평면도이고, 도 1b는 도 1a의 부분단면도이다. For example, in the accompanying drawings, FIG. 1A is a plan view showing the structure of a housing connector for a conventional flat cable, and FIG. 1B is a partial cross-sectional view of FIG. 1A.

상기 도면을 참조하면, 종래의 평면 케이블용 하우징 컨넥터(10)는 케이블(20)이 접속되어 안착되는 하우징부재(30)과, 상기 하우징부재(30)의 외측에 결합하여 하우징부재(30)를 보호하는 셀부재(40)와, 상기 하우징부재(30)의 전면 양측에 구비되어 PCB본체(미도시)와 결합한 후 이탈되는 것을 방지하는 고정레버(50) 로 구성된다.Referring to the drawings, the housing connector 10 for a conventional flat cable is coupled to the housing member 30 and the housing member 30 to which the cable 20 is connected and seated to the housing member 30 It is composed of a cell member 40 to protect, and a fixed lever 50 provided on both sides of the front surface of the housing member 30 to prevent the separation after being coupled with the PCB body (not shown).

이와 같이 구성되는 종래의 하우징 컨넥터(10)의 하우징부재(30) 내측에는 삽입홀(미도시)이 형성되어 있어, 평면 케이블(FFC)의 컨택트(31) 부분이 삽입/고정되며, 이 결합체(10)가 PCB본체와 연결되는 것이다.An insertion hole (not shown) is formed inside the housing member 30 of the conventional housing connector 10 configured as described above, so that the contact 31 portion of the flat cable (FFC) is inserted / fixed, and the combination ( 10) is connected to the PCB body.

그러나, 상기와 같은 종래의 평면 케이블용 하우징 컨넥터는 다음과 같은 문제점이 있었다.However, the conventional housing connector for flat cables has the following problems.

먼저, 도 2를 및 도 3을 참조하면, 본 발명인 평면 케이블용 하우징 컨넥 터(100)는 하우징부재(110)와, 하우징보호셀(120)과, 레버부(130) 및 상부커버(140)로 구성된다.First, referring to Figures 2 and 3, the housing connector 100 for a flat cable of the present invention is the housing member 110, the housing protection cell 120, the lever 130 and the upper cover 140 It consists of.

-하우징부재(110)Housing member 110

상기 하우징부재(110)는 평면 케이블(200)의 컨택트(210) 부분이 내삽되어, PCB 본체(미도시)에 결합하는 장치로서, 이 하우징부재(110)의 내측에는 하우징부재(110)의 후방으로부터 평면 케이블(200)의 컨택트(210) 부분을 삽입할 수 있는 삽입구(111)가 형성되어 있다.The housing member 110 is a device in which a portion of the contact 210 of the flat cable 200 is interpolated and coupled to a PCB main body (not shown). The housing member 110 has a rear side of the housing member 110 inside the housing member 110. The insertion hole 111 into which the contact 210 portion of the flat cable 200 can be inserted is formed.

한편, 상기 하우징부재(110)에 삽입/결합하는 평면 케이블(200)은 평각형태의 도체를 일정간격으로 나열시켜 형성되는 도체면을 폴리에스터 등의 특수재질로 만든 필름(film)으로 코팅한 케이블로서, PCB 본체의 회로 내 또는 초소형의 전자 제품, 프린터, 스캐너, 핸드폰 등의 PCB 본체와 이 PCB 본체와 연결되어 데이터 통신을 담당하는 것이며, 이 평면 케이블(200)은 신호도체(211)와, 이 신호도체(211)의 외곽 양측면으로 접지도체(212)를 갖는다.On the other hand, the flat cable 200 to be inserted / coupled to the housing member 110 is a cable coated with a film made of a special material such as polyester on the conductor surface formed by arranging the conductors of the flat form at a predetermined interval For example, the PCB main body is connected to the PCB main body, such as a circuit board of a PCB main body or an ultra small electronic product, a printer, a scanner, a mobile phone, and the like, and is responsible for data communication. The flat cable 200 includes a signal conductor 211, The ground conductors 212 are provided on both outer sides of the signal conductor 211.

종래에는 상기 평면 케이블(200)은 하우징부재(110)에 접속된 후에 평면 케이블(200)의 컨택트(210) 부분이 하우징부재(110)로부터 유동이 발생하거나 이탈되는 문제점이 있었고, 이러한 점을 개선하기 위해 평면 케이블(200)의 가이드면에 접착제 나 양면 테이프를 붙여 이러한 유동 및 이탈 발생을 방지하였다.Conventionally, after the flat cable 200 is connected to the housing member 110, the contact 210 portion of the flat cable 200 has a problem in which a flow occurs or escapes from the housing member 110. In order to prevent the occurrence of such flow and departure by attaching an adhesive or double-sided tape to the guide surface of the flat cable (200).

이 과정에서 접착제 또는 양면 테이프를 붙이는 추가 공정에 따른 하우징 컨넥터의 생산성이 떨어지고, 설령 접착제 또는 양면 테이프를 이용하여 접착하더라도 완전한 접착이 이루어지지 않아 불량률이 높았다.In this process, the productivity of the housing connector was decreased due to the additional process of attaching the adhesive or the double-sided tape, and even if the adhesive was used by the adhesive or the double-sided tape, the defect rate was high because the complete adhesion was not achieved.

이러한 평면 케이블(200)의 하우징부재(110) 내에서의 유동 및 이탈 문제를 없애기 위해 본 발명에 따른 하우징 컨넥터(100)의 전면에는 상기 평면 케이블(200)의 컨택트(210)가 삽입된 후, 삽입된 컨택트(210) 부분이 안착될 수 있는 케이블안착홈(112)이 형성된다.After the contact 210 of the flat cable 200 is inserted into the front surface of the housing connector 100 according to the present invention in order to eliminate the flow and departure from the housing member 110 of the flat cable 200, A cable seating groove 112 through which the inserted contact 210 portion may be seated is formed.

따라서, 상기 평면 케이블(200)의 하우징부재(110)의 삽입구(111)를 통해 삽입된 후, 평면 케이블(200)의 컨택트(210) 부분은 상기 케이블안착홈(112)에 안착되어 좌/우 또는 전방으로 유동하지 않게 된다. 또한, 이러한 케이블안착홈(112)이 형성됨으로 인해, 상기 하우징부재(110)의 내부에 평면 케이블(200)을 삽입/결합시에 상기 케이블안착홈(112)이 가이드 역할을 하게 되어 조립이 매우 용이하게 된다.Therefore, after being inserted through the insertion hole 111 of the housing member 110 of the flat cable 200, the contact 210 portion of the flat cable 200 is seated in the cable seating groove 112 and left / right Or does not flow forward. In addition, since the cable seating groove 112 is formed, the cable seating groove 112 acts as a guide when the flat cable 200 is inserted / coupled into the housing member 110, thus assembling is very easy. It becomes easy.
