본 발명은 조인트 커넥터에 관한 것으로서, 더욱 상세하게는, 피메일하우징에 구비된 록킹부를 이용하여 피메일터미널이 삽입되면 1차 록킹을 수행하고, 피메일하우징을 메일캡에 결합하면서 메일캡에 구비된 이탈방지가압부재를 이용하여 록킹부를 가압하여 피메일터미널의 2차 록킹을 수행함으로써, 작업공수를 줄여주고, 부품수를 감소시켜 제조비용을 절감할 수 있는 조인트 커넥터에 관한 것이다.The present invention relates to a joint connector, and more particularly, when a female terminal is inserted using a locking part provided in a female housing, the first locking is performed, and the female housing is provided on the male cap while being coupled to the male cap. The present invention relates to a joint connector capable of reducing the number of working man-hours and reducing the number of parts by performing the secondary locking of the female terminal by pressurizing the locking part by using the separation preventing pressing member.

일반적으로, 조인트 커넥터는 피메일하우징이 메일캡에 결합됨으로써 둘 사이에 각각 구비된 터미널 사이가 전기적으로 연결된다. 이때, 피메일하우징에는 다수개의 터미널이 구비될 수도 있다. 그리고, 메일캡에는 다수개의 터미널 사이를 서로 연결하기 위한 버스바 타입(busbar type)의 터미널이 구비된다.In general, in the joint connector, the female housing is coupled to the male cap, so that the terminals respectively provided between the two are electrically connected. In this case, a plurality of terminals may be provided in the female housing. In addition, the mail cap is provided with a busbar type terminal for connecting a plurality of terminals to each other.

메일캡의 내부에 복수개의 단자핀들이 연결된 버스바가 구비되어 하나의 회로에서 복수의 회로로 전류를 분기하거나 반대로 복수개의 회로에서 하나의 회로로 전류를 통합하는 기능을 제공한다.A bus bar to which a plurality of terminal pins are connected is provided inside the male cap to provide a function of branching current from one circuit to a plurality of circuits or conversely integrating current from a plurality of circuits to one circuit.

Collision prevention surface portion 410 is formed to be inclined at both ends of the end portion of the pressing member 400 to prevent tooth.

피메일하우징(100)의 둘레에는 메일캡(300)의 내주면에 밀착되어 방수기능을 수행하는 씰링부재(500)가 구비된다.A sealing member 500 that is in close contact with the inner circumferential surface of the male cap 300 is provided around the female housing 100 to perform a waterproof function.

씰링부재(500)는 피메일하우징(100)의 둘레에 설치되는 씰링본체(510)와, 씰링본체(510)의 둘레에 형성되는 리브돌기(520)를 포함한다.The sealing member 500 includes a sealing body 510 installed around the female housing 100 and a rib protrusion 520 formed around the sealing body 510.

리브돌기(520)는 씰링본채(510)의 중심부에 형성되는 중간리브돌기(530)와, 중간리브돌기(530)의 좌우 양측에 각각 형성되는 외측리브돌기(540)를 포함한다.The rib protrusion 520 includes an intermediate rib protrusion 530 formed in the center of the sealing main body 510 and an outer rib protrusion 540 formed on both left and right sides of the intermediate rib protrusion 530, respectively.

중간리브돌기(530)는 좌우 대칭으로 형성된다,The intermediate rib protrusion 530 is formed symmetrically left and right,

외측리브돌기(540)는 중간리브돌기(530)에 접하지 않는 반대측 경사면이 중간리브돌기(530)에 접하는 경사면보다 더 길게 형성되는 것을 특징으로 한다. 그 이유는 씰링부재(500)가 메일캡(300)의 내측면에 접촉될 때 접촉면적을 증진시키거나, 외부 충격으로 급격하게 부딪치는 것을 방지하여 씰링부재(500)의 손상을 줄이기 위함이다.The outer rib protrusion 540 is characterized in that the opposite inclined surface not in contact with the intermediate rib protrusion 530 is formed longer than the inclined surface in contact with the intermediate rib protrusion 530. The reason is to reduce damage to the sealing member 500 by increasing the contact area when the sealing member 500 contacts the inner surface of the male cap 300 or by preventing a sudden bump due to external impact.

메일캡(300)에는 씰링부재(500)가 접촉 설치되는 수용공간을 제공하도록 피메일하우징(100)의 외경이 확장되는 외경확장부(550)가 형성된다.The male cap 300 is formed with an outer diameter expansion part 550 in which the outer diameter of the female housing 100 is expanded to provide an accommodation space in which the sealing member 500 is installed in contact.

외경경확장부(550)는 협소부위에서 확장부위로 갈수록 점차 경사지게 형성된다.The outer diameter expansion part 550 is formed to be gradually inclined from the narrow area to the expansion area.

이하, 첨부도면을 참조하여 본 발명의 일 실시예에 따른 조인트 커넥터의 작용 및 효과를 살펴보도록 한다.Hereinafter, the action and effect of the joint connector according to an embodiment of the present invention will be described with reference to the accompanying drawings.

도 6 및 도 7에 도시된 바와 같이, 피메일터미널(10)을 피메일하우징(100)의 접속홀부(110)에 삽입하면, 피메일터미널(10)이 진입할수록 분리부(210)를 지나 록킹돌기부(240)를 타고 넘게 되고, 탄성지지부(220)는 끼움홈부(230)측으로 젖혀지면서 진입한다.As shown in FIGS. 6 and 7, when the female terminal 10 is inserted into the connection hole 110 of the female housing 100, the female terminal 10 passes through the separation unit 210 as the female terminal 10 enters. It goes over the locking protrusion 240, and the elastic support 220 enters while being tilted toward the fitting groove 230.

연이어, 피메일터미널(10)이 진입이 더 이루어지면서, 록킹돌기부(240)가 걸림홈부(12)에 삽입되는 순간 젖혀졌던 탄성지지부(220)가 탄성 복원되어 록킹돌기부(240)가 걸림홈부(12)에 걸리면서 1차 록킹된다.Subsequently, as the female terminal 10 further enters, the elastic support part 220 that was bent at the moment when the locking protrusion 240 is inserted into the locking groove 12 is elastically restored so that the locking protrusion 240 becomes the locking groove ( 12) and locked first.

그 다음, 도 8 및 도 9에 도시된 바와 같이, 피메일터미널(10)이 설치된 피메일하우징(100)을 조인트핀터미널(310)이 설치된 메일캡(300)에 삽입하여 결합하면, 조인트핀터미널(310)의 단자핀(312)이 피메일터미널(10)에 삽입되어 접속되고, 이탈방지부재(400)가 끼움홈부(230)로 진입하여 탄성지지부(220)를 양측으로 벌려준다.Then, as shown in Figs. 8 and 9, when the female housing 100 in which the female terminal 10 is installed is inserted into the male cap 300 in which the joint pin terminal 310 is installed and coupled, the joint pin The terminal pin 312 of the terminal 310 is inserted into and connected to the female terminal 10, and the separation preventing member 400 enters the fitting groove 230 to open the elastic support 220 to both sides.

이때, 피메일하우징(100)과 메일캡(300)이 체결되면서 이탈방지부재(400)는 탄성지지부(220)를 최대한 벌려주게 되고, 탄성지지부(220)에 구비된 록킹돌기부(240)가 걸림홈부(12)에 가압 밀착되어 피메일터미널(10)이 2차 록킹되면서 피메일하우징(100)과 메일캡(300)의 체결이 완료된다.At this time, as the female housing 100 and the mail cap 300 are fastened, the separation preventing member 400 opens the elastic support 220 to the maximum, and the locking protrusion 240 provided on the elastic support 220 is caught. The female terminal 10 is secondarily locked by being pressed against the groove 12, thereby completing the fastening of the female housing 100 and the male cap 300.

따라서, 본 발명의 일 실시예에 따른 조인트 커넥터는, 피메일하우징에 구비된 록킹부를 이용하여 피메일터미널이 삽입되면 1차 록킹을 수행하고, 피메일하우징을 메일캡에 결합하면서 메일캡에 구비된 이탈방지가압부재를 이용하여 록킹부를 가압하여 피메일터미널의 2차 록킹을 수행함으로써, 작업공수를 줄여주고, 부품수를 감소시켜 제조비용을 절감할 수 있다.Therefore, the joint connector according to an embodiment of the present invention performs primary locking when a female terminal is inserted using a locking part provided in the female housing, and is provided on the male cap while coupling the female housing to the male cap. The second locking of the female terminal is performed by pressing the locking part by using the separated release preventing pressurizing member, thereby reducing the number of working man-hours and reducing the number of parts, thereby reducing manufacturing cost.

본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다.Although the present invention has been described with reference to the embodiments shown in the drawings, this is only illustrative, and those of ordinary skill in the field to which the technology pertains, various modifications and other equivalent embodiments are possible. I will understand.
