콘센트의 공용접지 연결구조{The common grounding connection method of the socket}The common grounding connection method of the socket

본 발명은 콘센트의 공용접지와 접지연결단자의 연결구조에 관한 것으로, 특히 연결을 위한 가공의 용이성과 연결작업의 용이성은 물론 연결된 상태에서의 긴밀한 연결성을 갖도록 한 것이다.The present invention relates to a connection structure of a common ground and a ground connection terminal of an outlet, and in particular, it is intended to have a close connection in a connected state as well as ease of processing for connection and ease of connection work.

현재 공용접지와 접지연결단자는 콘센트의 플러그가 연결되는 단자와는 별도로 접지를 위하여 사용되어지는데 콘센트의 플러그가 삽입되는 부분에 노출되어지는 복수의 공용접지와 상기 복수의 공용접지와 연결되어지는 접지연결단자로 이루어지는 것이다.Currently, the common ground and the ground connection terminal are used for grounding separately from the terminal to which the plug of the outlet is connected. A plurality of common grounds exposed at a portion where the plug of the outlet is inserted and a ground connected to the plurality of common grounds It is made of a connecting terminal.

따라서 이러한 공용접지와 접지연결단자는 전도가 가능한 금속재질을 사용하게 되고, 일정한 폭과 길이로 이루어지는 것이다.Therefore, such a common ground and ground connection terminal is made of a metal material capable of conduction, and is made of a constant width and length.

또한 연결된 상태에서 유동되지 않게 연결결합되어야 하는데 이는 국가기술표준원에서 고시한 전기생활용품안전법에 의하여 규정되어 있는 것이다.In addition, it must be connected and not flowed in the connected state, which is prescribed by the Electrical Appliances Safety Act announced by the National Institute of Technology and Standards.

따라서 공용접지와 접지연결단자가 연결된 상태에서 분리 불가능하게 결합연결되어야 하기 위하여 종래에는 용접의 방식을 사용하였으나 이럴 경우에 용접공정의 추가에 따른 원가의 상승과 동시에 용접시 발생되는 용접열에 의한 형태의 변형등의 문제점이 있을 수 있고, 용접이 불량할 경우에 분리되어지는 문제점등이 발생될 수 있는 것이다.Therefore, the welding method has been used in the prior art in order to be inseparably coupled while the common ground and the ground connection terminal are connected. There may be problems such as deformation, and separation problems may occur when welding is poor.

따라서 공용접지에는 관통홀의 테두리를 따라서 돌출관을 직립되게 구비하고, 상기 돌출관에 끼움되어지게 접지연결단자에는 끼움홀을 구비한 상태에서 상기 돌출관에 끼움홀을 끼움토록 한 후 상기 돌출관을 말아줌으로서 공용접지와 접지연결단자가 임의적인 빠짐이 방지토록 하면서 연결결합토록 한 것이다.Therefore, the common ground is provided with a protruding pipe upright along the periphery of the through-hole, and the fitting is provided with a fitting hole in the ground connection terminal to be fitted to the protruding pipe. As it is rolled up, the common ground and the ground connection terminals are prevented from randomly falling out, and the connection is made.

그러나 이럴 경우에 문제점이 돌출관을 커얼링가공법에 의하여 말아줄 경우에 공용접지와 접지연결단자가 긴밀한 밀착상태가 되지 못하게 되면서 유동에 의한 스파크 등의 발생으로 화재등의 우려가 존재하였던 것이다.However, in this case, when the protruding pipe was rolled up by the caulling process, the common ground and the ground connection terminals could not be in close contact, and there was a fear of fire due to the occurrence of sparks due to flow.

따라서 본원출원인이 이러한 문제점을 개선하고자 공용접지에는 원형으로 천공된 관통홀의 테두리에 상측으로 직립되는 복수의 직립편을 구비한 상태에서 상기 직립편이 삽입가능하게 접지연결단자에는 끼움홀을 구비한 후 상기 직립편의 외측으로 끼움홀을 삽입토록 한 후 상기 직립편을 외측으로 벌려 접지연결단자의 끼움홀의 외측을 가압토록 함으로서 공용접지와 접지연결단자가 회전되지 않으면서도 견고하고 긴밀한 연결상태를 유지토록 하여 종래의 문제점을 해소하였던 것이다.Therefore, in order to improve this problem, the applicant of the present application is provided with a fitting hole in the ground connection terminal so that the upright piece is insertable in a state where the common ground is provided with a plurality of upright pieces upright on the edge of the through-hole drilled in a circle. After inserting the fitting hole to the outside of the upright piece, open the upright piece to the outside to press the outside of the fitting hole of the ground connection terminal, so that the common ground and the ground connection terminal are not rotated to maintain a tight and close connection state. The problem was solved.

그러나 이러한 것의 단점은 공용접지에 직립편을 구비할 경우에 프레스 가공으로 관통홀을 형성하면서 동시에 직립편을 구비토록 하기 위한 부분따내기에 해당되는 노칭가공과 완전한 분리를 위한 쉬어링 가공과 따내기에 해당되는 블랭킹이나 아웃커팅작업에 의하여 절첩부를 구비토록 한 후 상기 절첩부을 직립되게 굽힘가공하여 직립편을 구비하게 되는데 이럴 경우에 관통홀이 원형으로 이루어지게 되면서 직립편을 형성하는 절첩부의 폭에 제한이 따르게 되는 것이고, 또한 상기 직립편에 끼움되어지는 끼움홀이 끼움된 상태에서 직립편을 좌우로 벌려주고 가압해야 하는 등의 제조상의 공정이 추가되어지면서 원가가 상승하게 되는 문제점이 존재하게 되는 것이다.However, the disadvantages of this are that when the upright piece is provided on the common ground, the through hole is formed by press working, and at the same time, the notching process corresponding to the partial picking to have the upright piece and the shearing process for complete separation and the shearing process are provided. After the folded portion is provided by a blanking or outcutting operation, the folded portion is bent to provide an upright piece. In this case, the through-hole is formed in a circular shape and the width of the folded portion forming the upright piece There will be a limitation, and there will also be a problem that the cost increases as manufacturing processes are added such as the need to spread and press the upright piece from side to side in a state in which the fitting hole fitted into the upright piece is fitted. will be.

따라서 본 발명에서는 이러한 문제점을 해소하기 위하여 프레스 가압공정만으로 가공 및 연결결합이 가능토록 한 것이다.Therefore, in the present invention, in order to solve this problem, it is possible to process and connect with only a press pressing process.

이를 위하여 공용접지에는 내측이 중공상으로 이루어지면서 상측으로 상면이 막힌 상태의 돌부만을 구현토록 하고, 접지연결단자에는 상기 돌부가 끼움되어지게 끼움홀을 구비한 후 상기 끼움홀에 돌부를 삽입토록 한 후 돌부의 상측에서 상면의 중심을 가압하여 돌부의 중심의 외측이 균일하게 벌어지면서 눌림부가 동일하게 눌림이 가능토록 함으로서 공용접지와 접지연결단자의 연결결합이 견고하면서 치밀하게 연결이 가능토록 한 것이다.To this end, the inside of the common ground is made of a hollow shape, and only the protrusion having the top surface blocked toward the upper side is implemented. The ground connection terminal is provided with a fitting hole to fit the protrusion, and then a protrusion is inserted into the fitting hole. After pressing the center of the upper surface from the upper side of the projection, the outer side of the center of the projection spreads evenly, so that the pressing section can be pressed equally, so that the connection between the common ground and the ground connection terminal is firm and tightly connected. .

따라서 간단한 프레스 공정만으로 공용접지에 돌부를 구비토록 하고, 상기 돌부에 끼움홀이 구비되는 접지연결단자를 끼움토록 한 후 프레스 가압만으로 연결결합됨으로 저렴한 생산이 가능하게 되면서 연결결합상태가 우수한 제품을 제공할 수 있게 되는 것이다.Therefore, a simple press process is provided to provide a protrusion on a common ground, and a ground connection terminal equipped with a fitting hole is provided on the common ground. You can do it.

이하 첨부도면에 의거 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도1 내지 도7에 도시된 바와 같이 본 발명의 구성은 공용접지(10)에는 내측이 중공상(12)으로 이루어지게 상측으로 상면이 막힌 돌부(11)를 구비하고, 상기 상면이 막힌 돌부(11)에 끼임되어지게 끼움홀(21)을 구비한 접지연결단자(20)로 이루어진다.As shown in Figures 1 to 7 the configuration of the present invention, the common ground (10) is provided with a projection (11) with an upper surface clogged upward so that the inner side is made of a hollow (12), and the upper surface is blocked ( 11) It is made of a ground connection terminal (20) having a fitting hole (21) to be pinched.

본 발명에서 상기 공용접지(10)의 돌부(11)에 접지연결단자(20)의 끼움홀(21)이 끼움된 상태에서 돌부(11)의 상측에서 상면의 중심을 프레스의 슬라이더에 장착된 상부금형(일명:펀치)(30)이 하강하면서 가압할 경우에 상부금형(30)의 구조를 중앙은 선단이 뾰족하게 돌출되는 돌출가압부(31)와 그 외측으로는 내입되게 만곡되어진 내입만곡면(32)이 환형태로 이루어지도록 한 후 돌부(11)의 상면을 가압하면 뾰족하게 돌출된 가압부(31)가 돌부(11)의 상면중앙을 가압하게 되면 돌부(11)의 상면 중앙이 눌림되어지면서 그 외측이 균일하게 외측으로 벌어지면서 눌림되어지게 눌림부(11a)가 구비되고, 이렇게 외측으로 펼쳐지면서 눌림되는 눌림부(11a)의 상측을 상부금형(30)의 내입만곡면(32)으로 누름토록 하면 접지연결단자(20)의 끼임홀(21)의 외측을 상기의 눌림부(11a)의 하단면이 접지연결단자의 끼임홀의 상면과 밀착되어 누름토록 되면서 공용접지(10)와 접지연결단자(20)가 연결결합되는 것이다.In the present invention, in the state where the fitting hole 21 of the ground connection terminal 20 is fitted to the protrusion 11 of the common ground 10, the center of the upper surface at the upper side of the protrusion 11 is mounted on the slider of the press. When the mold (aka: punch) 30 is pressed while descending, the center of the structure of the upper mold 30 is a protruding pressing portion 31 at which the tip is sharply protruding, and an inward curved surface that is curved to be inscribed outside. When the upper surface of the projection 11 is pressed after making the ring 32, the center of the upper surface of the projection 11 is pressed when the pressing portion 31 protruding sharply presses the center of the upper surface of the projection 11 As the outer side is uniformly spread outward, the pressing portion 11a is provided to be pressed, and thus the upper side of the pressing portion 11a that is pressed while being spread outward is inward curved surface 32 of the upper mold 30. When pressed to the outside of the pinhole (21) of the ground connection terminal 20, the pressing portion (11) The lower surface of a) is in close contact with the upper surface of the pinhole of the ground connection terminal, so that the common ground 10 and the ground connection terminal 20 are connected and coupled.

따라서 공용접지(10)의 돌부(11)에 끼임되어진 접지연결단자(20)의 끼임홀(21)의 테두리 외측이 돌부(11)의 눌림부(11a)에 의하여 눌림되어지면서 임의적인 빠짐도 방지되면서 긴밀한 연결결합상태를 유지할 수 있게 되는 것이다.Therefore, the outside of the rim of the fitting hole 21 of the ground connection terminal 20 sandwiched between the protruding portion 11 of the common ground 10 is pressed by the pressing portion 11a of the protruding portion 11 to prevent an arbitrary fall. In this way, it is possible to maintain a close connection state.

이때 프레스의 볼스터(도시생략)에는 상기한 구조의 상부금형(30)과 대응가능하게 하부금형(일명:다이)(40)이 고정되어지는 것이고 이때 도시된 바와 같이 상부금형(30)의 뾰족하게 돌출된 가압부(31)에 의하여 공용접지(10)의 돌부(11)의 상면의 중앙이 가압될 경우에 프레스의 볼스터에 장착되는 하부금형(40)은 상부금형(30)의 가압부(31)에 의하여 정확하게 돌부(11)가 가압될 수 있는 구조로 이루어지게 되는 것이다.At this time, the lower mold (aka: die) 40 is fixed to the upper mold 30 of the above structure to be fixed to the bolster (not shown) of the press. At this time, the upper mold 30 is sharply shown. When the center of the upper surface of the protruding portion 11 of the common ground 10 is pressed by the protruding pressing portion 31, the lower mold 40 mounted on the bolster of the press is the pressing portion 31 of the upper mold 30 ) Will be made of a structure that can be pressed accurately the projection (11).

이를 위하여 하부금형(40)에는 공용접지(10)의 돌부(11)의 내측으로 형성되는 중공상(12)에 끼움가능하게 돌축(41)을 구비하고 상기 돌축(41)은 상부금형(30)의 가압시 탄성작용토록 함으로서 돌부(11)가 가압될 경우에 형태변형이 없이 지지되면서도 상부금형(30)의 뾰족한 형태의 가압부(31)의 가압시 상면의 중앙이 정확하게 가압되면서 파손등이 없이 눌림부(11a)를 정확하게 구현될 수 있게 되는 것이다.To this end, the lower mold 40 is provided with a protrusion 41 so as to be fitted into the hollow 12 formed inside the protrusion 11 of the common ground 10, and the protrusion 41 is an upper mold 30 When the protrusion 11 is pressed by the elastic action during pressing, the center of the upper surface is accurately pressed when the pressing portion 31 of the pointed shape of the upper mold 30 is pressed while the shape of the upper mold 30 is pressed without damage. It will be possible to accurately implement the pressing portion (11a).

본 발명에서의 상부금형(30)의 중앙에 뾰족하게 돌출된 가압부(31)는 돌부(11)의 상면의 중앙을 가압하게 되는 것이고, 본 발명에서 상기 돌부(11)의 상면의 형태를 만곡되어진 형태로 가공할 경우에 가압부(31)로 가압할 경우에 눌림부(11a)의 눌림되어지는 면적이 돌부의 상면이 만곡되어질 경우에는 평면보다도 돌부(11)의 상면의 면적이 많아지기 때문에 많아 질 수 있는 장점이 있는 것이다.In the present invention, the pressing portion 31 protruding sharply in the center of the upper mold 30 is to press the center of the upper surface of the projection 11, and in the present invention, the shape of the upper surface of the projection 11 is curved. When processing into the pressed form, when the pressing portion 31 presses the pressed area of the pressing portion 11a, when the upper surface of the projection is curved, the area of the upper surface of the projection 11 is larger than the flat surface. There is an advantage that can be increased.

그러나 이렇게 뾰족하게 돌출된 가압부(31)로 인하여 정확하게 중앙을 가압할 수 없게 될 경우에는 도2에 도시된 바와 같이 돌부(11)의 상면을 거의 평면으로 할 경우에는 가압부(31)의 가압이 좀더 용이한 반면에 돌부(11)의 상면이 눌림될 경우에 눌림부(11a)의 눌림폭이 작아지게 되지만 용이한 눌림이 가능토록 할 수 있게 되는 것이고, 가공시 불량률도 줄일 수 있게 되는 장점이 있는 것이다.However, when it is impossible to accurately press the center due to the sharply projecting pressing portion 31, as shown in FIG. 2, when the upper surface of the projection 11 is almost flat, the pressing portion 31 is pressed. On the other hand, when the upper surface of the projection 11 is pressed, the pressing width of the pressing portion 11a is reduced, but it is possible to facilitate the pressing, and the defect rate can be reduced during processing. There is this.

또한 본 발명에서의 공용접지(10)에 구현되는 돌부(11)는 프레스 공법에 의하여 구현가능토록 되는 것이고, 이러한 방식은 드로잉공법에 의하여 구현가능하거나 또는 프레스의 가압만으로도 구현가능하게 될 수 있는 것이다.In addition, the protrusion 11 implemented on the common ground 10 in the present invention is to be implemented by the press method, and this method can be implemented by the drawing method or can be realized only by pressing the press. .
