Description

커넥터{CONNECTOR}Connector {CONNECTOR}

본 발명은 커넥터에 관한 것으로서, 더욱 상세하게는, 터미널부가 하우징의 접속홀부에 덜삽입되더라도 푸쉬안내부를 이용하여 덜삽입된 터미널부를 푸쉬하여 이탈방지부재에 걸리게 하므로 터미널부의 이탈을 방지하고, 유동방지부를 구비하여 터미널부의 삽입을 최대치로 유지시켜 암수 단자간 유효접촉거리를 최대로 확보함으로써, 전기적 접촉 신뢰성을 높일 수 있는 커넥터에 관한 것이다.The present invention relates to a connector, more specifically, even if the terminal portion is less inserted into the connection hole of the housing, it pushes the less inserted terminal portion using the push guide portion to catch the release preventing member, thereby preventing the terminal portion from falling off and preventing flow. The present invention relates to a connector capable of increasing electrical contact reliability by providing a portion to keep the insertion of the terminal portion at a maximum value to secure an effective contact distance between male and female terminals.

최근들어서 점차적으로 일반차량, 하이브리드 자동차나 전기 자동차는 고전압/고전류를 사용하게 되므로, 차량의 외부로부터 공급되는 전원을 차량 내부의 부품에 안정적으로 공급 및 분배하기 위한 전기장치를 필요로 하게 된다. 뿐만 아니라, 차량의 전자제어를 위하여 많은 부품들이 모듈 형태로 제작되고 있으며, 사용전류나 전기신호를 전송하기 위하여 커넥터가 연결된 전선이나 통신선들의 사용이 급격히 증가하였다.In recent years, since a general vehicle, a hybrid vehicle, or an electric vehicle gradually uses high voltage / high current, an electric device for stably supplying and distributing power supplied from the outside of the vehicle to parts inside the vehicle is required. In addition, many components are manufactured in the form of modules for electronic control of vehicles, and the use of wires or communication lines to which connectors are connected to transmit electric current or electrical signals has rapidly increased.

이러한, 커넥터(CONNECTOR)는 자동차의 부품을 전기적으로 연결하기 위하여 사용되며, 자동차의 부품에 장착되었 을 때 전기적인 불량이 발생하지 않도록 여러 가지 안전검사를 거치게 된다. 그리고, 통상의 커넥터는 상호 탈착되는 암하우징과 숫하우징을 구비하며, 상호 결합된 암하우징과 숫하우징이 고정부재의 결합을 통해 분리되는 것이 방지된다.The connector (CONNECTOR) is used to electrically connect parts of a vehicle, and when mounted on parts of a vehicle, various safety tests are performed to prevent electrical defects. In addition, the conventional connector is provided with a male housing and a male housing that are detached from each other, and the mutually coupled female housing and the male housing are prevented from being separated through the coupling of the fixing member.

이때, 커넥터의 하우징에는 터미널부가 삽입되어 결합되기 전에 터미널부의 걸림을 유지하고 터미널부의 덜삽입을 검지하는 TPA(이하, 이탈방지부재라 함)가 설치된다.At this time, the housing of the connector is installed with a TPA (hereinafter referred to as an anti-separation member) that maintains the jamming of the terminal portion and detects less insertion of the terminal portion before being inserted and coupled.

이러한 이탈방지부재의 주된 기능은 터미널부의 위치 확인을 통한 터미널부의 덜삽입 검지 및 터미널부의 이탈을 하우징 내부의 란스부에 걸리는 1차 걸림과 더불어 2차 걸림을 통해 이중으로 고정시켜주는 역할을 수행한다.The main function of the departure prevention member serves to fix the insertion of the terminal part less through detection of the position of the terminal part and to fix the separation of the terminal part in a double way through the primary and secondary jams on the lance in the housing. .

그런데, 종래에는 터미널부의 완전한 덜삽입이 이루어지는 경우에는 이탈방지부재가 터미널부의 전체면에 간섭되어 쉽게 덜삽입에 대해 검지가 가능하지만, 터미널부의 덜삽입 거리가 1mm 이하의 경우에는 덜삽입의 검지가 어려워지는 단점이 있다.However, in the prior art, when the terminal part is completely inserted, the release preventing member interferes with the entire surface of the terminal part to easily detect less insertion, but when the terminal part has a less insertion distance of 1 mm or less, detection of less insertion It has the disadvantage of becoming difficult.

또한, 커넥터가 소극의 경우에는 큰 관계가 없지만, 다극일수록 커넥터의 너비가 길어져 중간지점에서의 덜삽입 발생의 경우에는 양측 사이드의 이탈방지부재의 걸림후크구조는 록킹이 이루어지더라도 중간부위가 볼록하게 튀어나온 배불뚝이 결합이 이루어짐으로써, 터미널부가 이탈방지부재에 걸림이 유지되지 못하여 이탈되는 문제점이 있다.In addition, although the connector does not have a great relationship in the case of a negative electrode, in the case of multi-pole, the width of the connector becomes longer, so in the case of less insertion at the intermediate point, the locking hook structure of the release preventing member on both sides is convex even though the locking is made. Since the bent pot protruding is made to be coupled, there is a problem in that the terminal portion is detached because the jam is not maintained in the departure preventing member.

따라서, 이를 개선할 필요성이 요청된다.Therefore, there is a need to improve this.

도 4에 도시된 바와 같이, 가압경사면부(424)의 경사각도는 진입경사면부(422)의 경사각도에 비해 수평면에 대하여 더 경사지게(크게) 형성된다. 이로써, 터미널부(200)는 가압경사면부(424)에서 수축되었던 팽창력이 수평방향 푸쉬 탄성 가압이동력으로 전환되어 진입이 촉진되어 이탈방지부재(300)에 걸려진다. 이때, 이탈방지부재(300)에 유동방지돌부(500)가 있는 경우에는 가압경사면부(424)를 통해 유동방지돌부(500)에 걸림 장착된다.4, the inclination angle of the pressing inclined surface portion 424 is formed to be inclined (larger) relative to the horizontal surface compared to the inclination angle of the inclined inclined portion 422. As a result, the terminal portion 200 is converted into a horizontal push elastic pressing movement force, which has been contracted in the pressing slope surface portion 424, is promoted to enter, and is caught by the departure preventing member 300. In this case, when the flow prevention protrusion 500 is provided on the departure prevention member 300, the flow prevention protrusion 500 is fastened to the flow prevention protrusion 500 through the pressure inclined surface 424.

한편, 가압경사면부(424)의 시작부위는 연통부(310)의 상측면에 배치됨으로써, 기존에는 연통부(310)에 터미널부(200)의 단턱부(210)가 덜삽입된 상태로 배치되는 경우, 걸림이 유지되지 못하여 터미널부(200)가 빠지는 데 반하여, 본 발명의 가압경사면부(424)에 터미널부(200)의 단턱부(210)가 도달하면, 푸쉬 탄성 가압력에 의해 수평방향으로 이동하여 자동적으로 걸림이 이루어지므로 터미널부(200)의 이탈을 간편하게 방지할 수 있다.On the other hand, the starting portion of the pressing inclined surface portion 424 is disposed on the upper side of the communication portion 310, so that the existing stepped portion 210 of the terminal portion 200 is less inserted into the communication portion 310 In the case that the terminal part 200 is pulled out because the jam cannot be maintained, when the stepped part 210 of the terminal part 200 reaches the pressure inclined surface part 424 of the present invention, the horizontal direction is caused by the push elastic pressing force. By moving to the automatic jam is made, it is possible to easily prevent the departure of the terminal unit 200.

즉, 가압경사면부(422)는 터미널부(200)의 진입시 상하간격이 오므려지도록 압축되였다가, 수평안내면부(426)에서 수축된 상태로 진입되고, 가압경사면부(424)에 다다르면서, 수축되었던 터미널부(200)가 확장될려는 탄성력으로 전환되어 가압경사면부(424)에서 수평방향 푸쉬이동력을 받아 자동적으로 가압경사면부(424)를 지나 이탈방지부재(300)의 걸림부위에 걸려 이탈이 방지된다. 이로써, 터미널부(200)는 덜삽입이 이루어더라도 가압경사면부(424)에 도달하기만 하면 자동적으로 푸쉬 가압탄성력을 받으면서 이탈방지부재(300)의 걸림부위에 걸려진다.That is, the pressurized inclined surface portion 422 is compressed to close the vertical gap when entering the terminal portion 200, enters the contracted state in the horizontal guide surface portion 426, and reaches the pressurized inclined surface portion 424, The terminal portion 200, which has been contracted, is converted into an elastic force to be expanded, receives a horizontal push movement force from the pressure inclined surface portion 424, automatically passes through the pressure inclined surface portion 424, and is caught and detached from the engaging portion of the departure preventing member 300 This is prevented. As a result, even if less insertion is made, the terminal unit 200 is automatically caught by a push-pressing elastic force and is caught in the locking portion of the departure-preventing member 300 as long as it reaches the pressing inclined surface portion 424.

이때. 유동방지돌부(500)가 가압경사면부(424)와 접하여 있는 경우, 터미널부(200)의 단턱부(210)는 가압경사면부(424)를 거쳐 유동방지돌부(500)에 의해, 더 진입되는 상태로 이탈방지부재(300)에 걸려지게 된다. At this time. When the flow prevention protrusion 500 is in contact with the pressure inclined surface portion 424, the stepped portion 210 of the terminal portion 200 passes through the pressure inclined surface portion 424, by the flow prevention protrusion 500, further entering In the state it is caught in the departure prevention member 300.

이탈방지부재(300)에는 터미널부(200)의 유동을 방지하도록 터미널부(200)의 단턱부(210)를 밀어주는 유동방지돌부(500)가 구비될 수 있다.The departure preventing member 300 may be provided with a flow prevention protrusion 500 that pushes the stepped portion 210 of the terminal portion 200 to prevent the flow of the terminal portion 200.

이때. 유동방지돌부(500)는 이탈방지부재(300)의 걸림 측면으로부터 더 돌출되도록 유동방지구간(b)의 두께만큼 형성됨으로써, 터미널부(200)의 덜삽입시 최대치로 삽입되도록 안내해주고, 이는 암수단자 간의 유효접촉거리를 최대한 확보 가능하게 함에 따라 전기적인 접촉 가능성을 최고로 확보할 수 있게 해준다.At this time. The flow prevention protrusion 500 is formed by the thickness of the flow prevention section (b) so that it protrudes further from the locking side of the departure prevention member 300, thereby guiding it to be inserted at the maximum value when the terminal 200 is inserted less, which is male and female. As the effective contact distance between terminals can be secured as much as possible, the possibility of electrical contact can be secured to the maximum.

하우징(100)에는 이탈방지부재(300)가 장착홈부(120)에 결합시 유동방지돌부(500)가 걸리는 것을 방지하도록 삽입을 안내하는 회피홈부(600)가 형성될 수 있다. 회피홈부(600)는 유동방지돌부(500)에 대응되게 형성된다.The housing 100 may be formed with an escape groove 600 to guide the insertion to prevent the flow prevention protrusion 500 from being caught when the release preventing member 300 is coupled to the mounting groove 120. The avoidance groove 600 is formed to correspond to the flow prevention protrusion 500.

따라서, 본 발명의 일 실시예에 따른 커넥터는, 터미널부가 하우징의 접속홀부에 삽입되어 이탈방지부재를 관통하여 결합함에 있어 터미널부가 하우징의 접속홀부에 덜삽입되더라도 푸쉬안내부를 이용하여 덜삽입된 터미널부를 푸쉬하여 이탈방지부재에 걸리게 함으로써, 하우징에서 터미널부의 덜삽입에 따른 이탈을 방지할 수 있다. 또한, 본 발명은, 유동방지부를 이용하여 터미널부의 삽입을 최대치로 유지시켜 암수 단자간 유효접촉거리를 최대로 확보함으로써, 단자간 전기적 접촉 신뢰성을 높일 수 있다.Therefore, in the connector according to an embodiment of the present invention, the terminal portion is inserted into the connection hole portion of the housing and penetrates through the separation preventing member, so that the terminal portion is less inserted using the push guide portion even though the terminal portion is less inserted into the connection hole portion of the housing. By pushing the portion to be caught in the release preventing member, it is possible to prevent departure due to less insertion of the terminal portion in the housing. In addition, according to the present invention, it is possible to increase the electrical contact reliability between terminals by keeping the insertion of the terminal portion at a maximum by using a flow prevention portion to secure the effective contact distance between the male and female terminals to the maximum.
