Each terminal provided as described above is to send or receive a signal by a plug connected from other electronic products, so that the image or audio can be connected to other electronic devices.

따라서 종래에는 도1내지 도3에 도시한 바와 같이 잭(21)의 전방에 안내부(23)에 의하여 지지되는 접지부(22)를 돌출시키고, 상기 안내부(23)의 안쪽으로 각종 단자가 삽입될 수 있는 접속홈(24)을 형성하며, 상기 접속홈(24)의 내부 후방에 탄발력을 갖는 접촉구(25)에 일체인 접촉편(25b)과 접속구(26)가 서로 접하도록 구성하였다. 또한 접촉구(25)의 후방에 구비한 접촉부(25a)와, 접속구(26)의 후방에 구비한 접속부(26a)를 고정홈(27)에 삽입하여 고정시킨 것이며, 상기 잭(21)의 후방에 접속방지판(29)을 고정시킬 수 있는 고정돌기(28)를 구성한 것이었다. 그리고, 접촉부(25a)와 접속부(26a)에 전기적으로 연결하기 위한 접속연결구(30)와, 접지부(22)에 연결한 접지구(31)를 인쇄회로기판에 연결하는 것이었다.Therefore, in the related art, as illustrated in FIGS. 1 to 3, the ground part 22 supported by the guide part 23 protrudes in front of the jack 21, and various terminals are provided inside the guide part 23. Forming a connection groove 24 that can be inserted, the contact piece 25b and the connection port 26 integral with the contact hole 25 having a resilient force in the inner rear of the connection groove 24 is configured to contact each other It was. Moreover, the contact part 25a provided in the back of the contact hole 25 and the connection part 26a provided in the back of the connection port 26 were inserted and fixed in the fixing groove 27, and the rear of the said jack 21 was carried out. The fixing protrusion 28 which can fix the connection preventing plate 29 to the structure was comprised. Then, the connecting connector 30 for electrically connecting the contact portion 25a and the connecting portion 26a and the grounding hole 31 connected to the ground portion 22 were connected to the printed circuit board.

상기와 같이 구성된 종래에는 잭(21)을 사용하기 위하여 각종 단자를 삽입하게 되면 안내부(23)의 내부인 접속홈(24)에 플러그가 삽입되어 접촉구(25)의 접촉편(25b)을 안내부(23)의 방향으로 밀게 되었고, 이때 접촉구(25)의 접촉편(25b)이 밀리면서 접속홈(24)에 삽입된 플러그를 감싸게 되고, 상기 접촉편(25b)에 의해 감싸인 플러그는 잭(21)과 전기적으로 연결되었다. 상기 접촉구(25)와 접속구(26)는 접속연결구(30)에 의하여 플러그에 전기적 신호를 전달하게 되었다. 또한 플러그의 외면부는 잭(21)의 접지부(22)에 연결되어 접지구(31)를 통하여 외부와 접지되었다. 상기와 같이 연결된 플러그를 잭(21)에서 이탈시키게 되면 접촉구(25)와 접속구(26)를 외측으로 밀었던 힘이 제거되고, 접촉구(25)의 접촉편(25b)과 접속구(26)는 탄발력에 의하여 원상태로 회복되면서 접하게 되었다. 상기와 같이 접하게 된 접촉편(25b)와 접속구(26)는 단자가 비삽입 상태에서도 전기를 통하는 상태가 유지되었다.In the conventional configuration configured as described above, when various terminals are inserted in order to use the jack 21, the plug is inserted into the connection groove 24 which is the inside of the guide portion 23, thereby contacting the contact piece 25b of the contact hole 25. Pushed in the direction of the guide portion 23, at this time, the contact piece 25b of the contact hole 25 is pushed to wrap the plug inserted into the connection groove 24, the plug wrapped by the contact piece 25b Is electrically connected to the jack 21. The contact port 25 and the connector 26 are to transmit an electrical signal to the plug by the connector 30. In addition, the outer surface portion of the plug is connected to the ground portion 22 of the jack 21 and grounded to the outside through the grounding hole (31). When the plug connected as described above is released from the jack 21, the force pushing the contact hole 25 and the connection port 26 outward is removed, and the contact piece 25b and the connection port 26 of the contact hole 25 are removed. Was brought back to the original state by force. The contact piece 25b and the contact port 26 which were brought into contact with the above were maintained in a state where electricity was transmitted even when the terminal was not inserted.

그러나 상기 잭(21)에 어린이가 장난으로 젓가락등의 가늘고 긴 도체를 삽입하거나 이용자의 부주의로 인하여 드라이버등의 도체가 접속홈(24)에 삽입된 경우 잭(21)의 후방에 구비된 인쇄회로기판에 도체가 접하게 되어 전기가 통하게 되고, 이때 도체체 접하고 있던 이용자가 전기에 의한 감전이 유발되었다.However, when a child inserts an elongated conductor such as a chopstick or the like into the jack 21 or a conductor such as a driver is inserted into the connecting groove 24 due to user's carelessness, the printed circuit provided at the rear of the jack 21. The conductor was brought into contact with the substrate, and electricity was passed through. At this time, the user who was in contact with the conductor caused an electric shock.

인쇄회로기판의 각종 소자나 회로에 도체가 접하게 될 때 인쇄회로기판을 통하고 있던 전기는 미세한 전류에서부터 전원에서 인가받은 강한 전류가 포함되어 있으며, 상기 여러 전류 중에서 상기 강한 전류등이 이용자에게 도체에 의하여 전달 될 경우 전기적인 쇼크를 주거나 제품에 대한 좋지않은 감정을 유발하여 잭(21)에 대하여 좋지 않은 감정이 발생되었다.When a conductor comes into contact with various elements or circuits of a printed circuit board, electricity flowing through the printed circuit board includes a strong current applied from a small current to a power source. Among the various currents, the strong current is supplied to the conductor. When delivered by the electric shock or caused a bad feeling for the product caused a bad feeling for the jack 21.

따라서 상기와 같은 경우를 예방하기 위하여 잭(21)의 후방에 구비된 고정돌기(28)에 결합된 접속방지판(29)에 의하여 도체가 삽입되더라도 잭(21)의 후방에 위치한 인쇄회로기판에 도체가 접하지 않게 되어 전기적인 연결이 방지되었다. 그러나 상기의 경우 어린이나 부주의 한 이용자가 잭(21)의 접속홈(24)에 도체를 삽입시킨 경우 고정돌기(28)에 의하여 고정된 접속방지판(29)이 도체가 삽입되는 충격에 의하여 고정돌기(28)에서 이탈되는 경우도 발생되었다. 또한 상기와 같이 고정돌기(28)와 접속방지판(29)이 잭(21)에 구비된 경우 추가로 부품이 필요하게 되며, 조립공정이 증가되는 단점이 있었다.Therefore, in order to prevent such a case, even if the conductor is inserted by the connection preventing plate 29 coupled to the fixing projection 28 provided at the rear of the jack 21 to the printed circuit board located at the rear of the jack 21. The conductors are not in contact, preventing electrical connections. However, in the above case, when the child or careless user inserts the conductor into the connecting groove 24 of the jack 21, the connection preventing plate 29 fixed by the fixing protrusion 28 is fixed by the impact of the conductor being inserted. There was also a case of departure from the projections 28. In addition, when the fixing protrusion 28 and the connection preventing plate 29 is provided in the jack 21 as described above, additional components are required, and there is a disadvantage in that the assembling process is increased.

그리고 상기 잭(21)은 플러그가 접속홈(24)에 삽입될 때 플러그를 안내하여 주는 구성이 되어 있지 않아 플러그가 오삽입되어 접촉면(25b)을 안내부(23)의 방향과 반대인 접속구(26)의 방향으로 밀어 잭(21)의 불량 원인이 되었다. 또한 플러그가 여려번 반복하여 잭(21)의 접속홈(24)에 삽입되는 경우 접촉구(25)가 탄발력을 상실하여 플러그의 삽입 시 플러그와 접촉편(25b)이 전기적인 연결이 되지 않는 경우도 발생하였다.In addition, the jack 21 is not configured to guide the plug when the plug is inserted into the connection groove 24, so that the plug is misinserted so that the contact surface 25b is opposite to the direction of the guide portion 23 ( It was pushed in the direction of 26 to cause a failure of the jack 21. In addition, when the plug is repeatedly inserted into the connecting groove 24 of the jack 21 several times, the contact hole 25 loses elasticity, and thus the plug and the contact piece 25b are not electrically connected when the plug is inserted. A case also occurred.

따라서 본 발명은 상기와 같은 단점을 효과적으로 제거하기 위하여 접속부에 일체인 삽입방지편과, 접촉구에 일체인 안내편과 날개편 및 볼록구에 의하여 어린이나 이용자의 부주의로 도체가 잭에 삽입되었을 때 삽입방지편에 막히게 되어 감전되는 경우를 사전에 방지할 수 있으며, 플러그의 삽입을 원할히 하고, 플러그와 단자의 접촉성을 향상시키며, 생산원가를 절약하며, 조립성을 향상하는 것에 그 목적이 있다.Therefore, the present invention, when the conductor is inadvertently inserted into the jack by the child and the user by the insertion prevention piece integral to the connecting portion, the guide piece integral to the contact and the wing piece and the convex port in order to effectively eliminate the above disadvantages. The purpose of this is to prevent the electric shock due to blockage of the insertion prevention piece, to facilitate the insertion of the plug, to improve the contact between the plug and the terminal, to reduce the production cost, and to improve the assembly. .

따라서 본 발명은 플러그가 삽입되는 접속홈의 내부에 접촉구에 일체로 날개편과 안내편 및 볼록구를 형성하며, 잭이 후방에 접속부와 일체로 삽입방지편을 연결 구성하고, 상기 삽입방지편을 접속홈에서 이어지는 통로에 수직으로 삽입방지편을 구비하며, 상기 삽입방지편의 중앙에 삽입방지턱을 형성함으로써, 이용자의 감전사고를 예방하고, 생산성을 향상시키도록 한 것이다.Therefore, the present invention forms a wing piece, a guide piece and a convex ball integrally with the contact hole in the connection groove into which the plug is inserted, and the jack is configured to connect the insertion prevention piece integrally with the connection part at the rear, and the insertion prevention piece The insertion prevention piece is provided perpendicularly to the passage leading from the connection groove, and by forming an insertion prevention jaw in the center of the insertion prevention piece, it is to prevent the electric shock accident of the user, to improve the productivity.
