본 고안은 전등핀에 관한 것으로서, 보다 상세하게는 전등의 외부로 노출된 리드선과 소켓단자사이를 전기적으로 연결하기 위해 전등에 설치되는 핀에 관한 것 이다.The present invention relates to a light pin, and more particularly to a pin installed in the light to electrically connect between the lead wire and the socket terminal exposed to the outside of the light.

전등은 소켓에 지지되고, 소켓을 통해 동작전압을 공급받을 수 있도록 소켓단자와 전등의 리드선사이를 연결하는 전등핀이 안출되어 사용되고 있다.The lamp is supported by the socket, and a light pin connecting between the socket terminal and the lead wire of the lamp is used to receive the operating voltage through the socket.

도7은 종래의 전등핀의 단면도이다.7 is a cross-sectional view of a conventional light pin.

종래의 전등핀은, 도7에 도시된 바와 같이, 도입관부(111)와, 도입관부(111)의 전단으로부터 연장 형성된 지지관부(112)와, 도입관부(111)의 외표면에 둘레방향을 따라 돌출 형성된 걸림플랜지(114)를 갖고 있다.As shown in FIG. 7, the conventional light pin has a circumferential direction on an outer surface of the introduction tube portion 111, the support tube portion 112 extending from the front end of the introduction tube portion 111, and the introduction tube portion 111. It has a latching flange 114 which protrudes along.

도입관부(111)는 지지관부(112)의 인접영역은 내경이 점점 감소하도록 형성되어 있다. 이에 따라 도입관부(111)와 지지관부(112)의 연결영역에는 단턱(111a)이 형성된다.The introduction pipe part 111 is formed so that the inner diameter of the support pipe part 112 is gradually reduced. Accordingly, the stepped portion 111a is formed in the connection region between the introduction pipe portion 111 and the support tube portion 112.

지지관부(112)는 내경이 일정하도록 도입관부(111)로부터 연장 형성되어 있고, 종단 외표면에는 경사면이 형성되어 있다.The support pipe part 112 is extended from the inlet pipe part 111 so that an internal diameter may be constant, and the inclined surface is formed in the terminal outer surface.

그리고 지지관부(112)는 도입관부(111)보다 작은 직경을 갖도록 형성된다. And the support tube 112 is formed to have a diameter smaller than the introduction tube portion (111).

이러한 구성을 갖는 종래의 전등핀은 황동과 같은 도전성 금속재질의 관소재(201)를 절단한 후(도8 참조), 아래와 같은 공정을 거쳐 제작된다.The conventional electric light pin having such a configuration is manufactured by cutting the tubular material 201 made of a conductive metal such as brass (see FIG. 8), and then performing the following process.

먼저 드릴공정으로 통해 도입관부(111)의 내경을 확장한다(도9 참조).First, the inner diameter of the introduction pipe portion 111 is expanded through a drill process (see FIG. 9).

다음에 지지관부(112)의 외표면에 경사면을 형성한다.Next, an inclined surface is formed on the outer surface of the support pipe portion 112.

마지막으로 가압소성공정을 통해 도입관부(111)의 외표면에 걸림플랜지(114)를 형성한다.Finally, the engaging flange 114 is formed on the outer surface of the introduction pipe part 111 through a pressurizing firing process.

종래의 전등핀을 사용하는 방법을 도10을 참조하여 설명하면 다음과 같다.A method of using a conventional light pin will be described with reference to FIG. 10.

먼저 한 쌍의 절연체(211a)가 걸림플랜지(114)의 후방영역에 배치되도록 전등핀을 램프캡(211b)에 설치한다.First, the light pin is installed in the lamp cap 211b so that the pair of insulators 211a are disposed in the rear region of the locking flange 114.

다음에 도입관부(111)의 후방영역을 외측으로 절곡시킨다.Next, the rear region of the introduction pipe section 111 is bent outward.

다음에 리드선(211c)이 도입관부(111)를 통과하여 지지관부(112)에 도달하도록 램프캡(211b)을 램프(211d)에 결합시킨다.Next, the lamp cap 211b is coupled to the lamp 211d so that the lead wire 211c passes through the introduction tube part 111 to reach the support tube part 112.

다음에 펀치핀(204)으로 지지관부(112)를 가압하여 리드선(211c)을 지지관부(112)의 내표면에 가압상태로 접촉시킨다.Next, the support pipe portion 112 is pressed with the punch pin 204 to bring the lead wire 211c into contact with the inner surface of the support pipe portion 112 in a pressurized state.

그런데 종래의 전등핀에 따르면, 도입관부(111)의 내경을 확장하는 공정, 지지관부(112)의 외표면에 경사면을 형성하는 공정 및 도입관부(111)의 외표면에 걸림플랜지(114)를 형성하는 공정을 각각 별도로 거쳐 제조하여야 하기 때문에 제조공정이 복잡하다는 문제점이 있었다.By the way, according to the conventional light pin, the step of expanding the inner diameter of the introduction tube portion 111, the step of forming a slope on the outer surface of the support tube portion 112 and the engaging flange 114 on the outer surface of the introduction tube portion 111. There is a problem in that the manufacturing process is complicated because it must be manufactured separately through each forming process.

그리고 지지관부(112)의 두께가 도입관부(111)보다 크기 때문에 펀치핀(204)이 쉽게 손상된다는 문제점이 있었다.And since the thickness of the support pipe 112 is larger than the introduction pipe 111, there was a problem that the punch pin 204 is easily damaged.

또한 펀치핀(204)의 가압점에서 리드선(211c)과 지지관부(112사이의 전기적 연결이 이루어지기 때문에 리드선(211c)과의 전기적 접촉이 불량해지거나 전기적 접촉면적이 작아진다는 문제점이 있었다. In addition, since the electrical connection is made between the lead wire 211c and the support tube 112 at the pressing point of the punch pin 204, there is a problem that the electrical contact with the lead wire 211c becomes poor or the electrical contact area becomes small.

따라서 본 고안의 목적은, 제조공정이 간단하고 펀치핀의 손상을 줄일 수 있으며며, 리드선과의 전기적 연결이 안정적으로 이루어질 수 있도록 한 전등핀을 제공하는 것이다.Therefore, an object of the present invention is to provide a light pin that can simplify the manufacturing process and reduce damage to the punch pin, and to make the electrical connection with the lead wire stable.

상기 목적은, 본 고안에 따라, 전등의 외부로 노출된 리드선과 소켓단자사이를 전기적으로 연결하기 위해 상기 전등에 설치되는 전등핀에 있어서, 일정한 내경을 갖는 도입관부와; 상기 도입관부와 동일한 두께를 가지고, 상기 도입관부의 전단으로부터 내경이 점점 감소하도록 연장 형성된 지지관부와; 상기 도입관부의 외표면에 둘레방향을 따라 돌출 형성된 걸림플랜지를 포함하는 것을 특징으로 하는 전등핀에 의해 달성된다.The above object is, according to the present invention, in the light pin is installed on the lamp to electrically connect between the lead wire and the socket terminal exposed to the outside of the lamp, the introduction pipe portion having a constant inner diameter; A support tube portion having the same thickness as that of the introduction tube portion and extending from the front end of the introduction tube portion to gradually decrease the inner diameter; It is achieved by a light pin characterized in that it comprises a locking flange protruding along the circumferential direction on the outer surface of the introduction tube.

여기서 소켓단자에 용이하게 삽입할 수 있도록, 상기 지지관부와 동일한 두께를 가지고, 일정한 내경을 갖도록 상기 지지관부의 전단으로부터 연장 형성된 삽입안내관부를 더 포함하도록 구성하는 것이 바람직하다.Here, it is preferable to further include an insertion guide tube portion extending from the front end of the support tube portion to have the same thickness as the support tube portion and to have a constant inner diameter so that the socket terminal can be easily inserted.

그리고 램프캡에 용이하게 설치할 수 있도록, 상기 도입관부의 외표면 상기 걸림플랜지의 후방영역에는 둘레방향을 따라 절곡보조홈을 함몰형성하는 것이 바람직하다.And it is preferable to form a recessed auxiliary groove bent in the circumferential direction in the rear region of the engaging flange of the outer surface of the introduction pipe portion to facilitate installation in the lamp cap.

이하에서, 첨부도면을 참조하여 본 고안을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안의 실시예에 따른 전등핀은, 이들 도면에 도시된 바와 같이, 일정한 내경을 갖는 도입관부(11)와, 도입관부(11)의 전단으로부터 연장형성된 지지관부(12)와, 지지관부(12)의 전단으로부터 연장 형성된 삽입안내관부(13)와, 도입관부(11)의 외표면에 둘레방향을 따라 돌출 형성된 걸림플랜지(14)를 갖고 있다.As shown in these drawings, the lamp pin according to the embodiment of the present invention has an introduction pipe portion 11 having a constant inner diameter, a support tube portion 12 extending from a front end of the introduction tube portion 11, and a support tube portion ( The insertion guide tube part 13 extended from the front end of 12), and the engaging flange 14 which protruded along the circumferential direction on the outer surface of the introduction tube part 11 are provided.

도입관부(11)는 외표면 걸림플랜지(14)의 후방영역에 절곡보조홈(11a)이 둘레방향을 따라 함몰 형성되어 있다.The introduction pipe part 11 is formed in the rear region of the outer surface engaging flange 14, the bent auxiliary groove (11a) is formed in the circumferential direction.

지지관부(12)는 도입관부(11)와 동일한 두께를 가지고, 내경이 점점 감소하도록 도입관부(11)로부터 연장 형성되어 있다.The support pipe part 12 has the same thickness as the inlet pipe part 11, and is extended from the inlet pipe part 11 so that an inner diameter may gradually decrease.

삽입안내관부(13)는 지지관부(12)와 동일한 두께를 가지고, 일정한 내경을 갖도록 지지관부(12)로부터 연장 형성된다.The insertion guide tube portion 13 has the same thickness as the support tube portion 12 and extends from the support tube portion 12 to have a constant inner diameter.

이러한 구성을 갖는 본 고안의 실시예에 따른 전등핀은 황동과 같은 도전성 금속재질의 관소재(201)를 절단한 후(도3 참조), 아래와 같은 가압소성공정을 거쳐 제작된다.The electric light pin according to the embodiment of the present invention having such a configuration is manufactured by cutting the tubular material 201 made of a conductive metal material such as brass (see FIG. 3), and then performing a pressure firing process as follows.

먼저 절단한 관소재(201)를 우금형(202)에 탑재한다(도4 참조).First, the cut tubular material 201 is mounted on the right mold 202 (see Fig. 4).

다음에 좌금형(203)과 우금형(202)이 접근하도록 양방향에서 직선상으로 압력을 가한다(도5 참조).Next, pressure is applied in a straight line in both directions so that the left mold 203 and the right mold 202 approach (see FIG. 5).

마지막으로 도입관부(11)의 외표면 걸림플랜지(14)의 후방영역을 압착하여 절곡보조홈(11a)을 함몰 형성한다.Finally, the rear region of the outer surface engaging flange 14 of the inlet pipe part 11 is pressed to form a recessed auxiliary recess 11a.

본 발명의 실시예에 따른 전등핀을 사용하는 방법을 도6을 참조하여 설명하면 다음과 같다.The method of using the light pin according to the embodiment of the present invention will be described with reference to FIG.

먼저 한 쌍의 절연체(211a)가 걸림플랜지(14)와 절곡보조홈(11a)사이에 개재하도록 전등핀을 램프캡(211b)에 설치한다.First, a light pin is installed in the lamp cap 211b so that a pair of insulators 211a are interposed between the locking flange 14 and the bending auxiliary groove 11a.

다음에 도입관부(11)의 절곡보조홈(11a) 후방영역을 외측으로 절곡시킨다.Next, the rear region of the bending auxiliary groove 11a of the introduction pipe portion 11 is bent outward.

다음에 리드선(211c)이 도입관부(11)를 통과하여 지지관부(12)에 도달하도록 램프캡(211b)을 램프(211d)에 결합시킨다.Next, the lamp cap 211b is coupled to the lamp 211d so that the lead wire 211c passes through the introduction pipe portion 11 and reaches the support tube portion 12.

다음에 펀치핀(204)으로 도입관부(지지관부에 접하는 영역)를 가압하여 리드선(211c)을 도입관부(11)의 내표면에 가압상태로 접촉시킨다. 여기서 펀치핀(204)의 가압동작이 충분한 경우 리드선(211c)은 도입관부(11)이외 지지관부(12)에도 접촉되기 때문에 리드선(211c)과 지지관부(12)사이의 전기적 접촉 면적이 넓어지게 된다. 그리고 펀치핀(204)의 가압동작이 부족하더라고 리드선(211c)의 종단이 지지관부(12)에 접촉됨으로써, 리드선(211c)과 지지관부(12)사이의 전기적 접촉을 유지할 수 있게 된다.Next, the lead pin 211c is brought into contact with the inner surface of the inlet pipe 11 by pressing the inlet pipe section (the area in contact with the support pipe section) with the punch pin 204. In this case, when the pressing operation of the punch pin 204 is sufficient, the lead wire 211c contacts the support tube part 12 as well as the introduction tube part 11 so that the electrical contact area between the lead wire 211c and the support tube part 12 is widened. do. In addition, even if the pressing operation of the punch pin 204 is insufficient, the end of the lead wire 211c comes into contact with the support tube portion 12, thereby maintaining electrical contact between the lead wire 211c and the support tube portion 12.

전등핀이 소켓단자에 접촉되도록 전등(211)은 소켓에 지지된다.The lamp 211 is supported by the socket so that the lamp pin contacts the socket terminal.

한편 전술한 실시예에서는 형광등에 본 고안의 전등핀을 사용하는 경우를 설명하고 있으나, 삼파장등과 같이 다른 전등에 본 고안의 전등핀을 사용할 수 있음은 물론이다.Meanwhile, in the above-described embodiment, the case where the light pin of the present invention is used for a fluorescent lamp has been described, but the light pin of the present invention can be used for another light such as a three-wavelength light.
