* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 플러그 본체 12 : 코드(Cord)1: Plug body 12: Cord

13 : 핀 14 : 압착부13: pin 14: crimping portion

15 : 핀홀더 16 : 심선15: pin holder 16: core

17 : 단락 방지용 핀17: short circuit prevention pin

본 고안은 플러그의 단락 방지 구조에 관한 것으로, 특히 단락 방지용 핀에 의해서 코드의 심선이 서로 붙어 단락되는 현상 및 플러그를 손으로 잡을 때 감전되는 것을 방지하는 데 목적이 있다.The present invention relates to a short circuit prevention structure of a plug, and in particular, the purpose of preventing the electric shock when the core wires of the cord by the short circuit prevention pins are attached to each other and short-circuited.

종래 기술 구성은 첨부도면 제 1 도에서 보는 바와 같이 핀홀더(4)에 핀(3)이 나일론수지로 몰딩되어 있고, 핀홀더(4) 압착부(5)의 구멍에 심선이 넣어져 프레스로 압착되어 있으며, 핀홀더(4) 및 코드(2)는 플러그 본체(1)로서 몰딩되어 있다.In the prior art configuration, as shown in FIG. 1 of the accompanying drawings, the pin holder 4 is molded with a nylon resin, and the core wire is inserted into the hole of the crimping portion 5 of the pin holder 4. It is crimped | bonded and the pin holder 4 and the cord 2 are molded as the plug main body 1.

사용자가 플러그를 콘센트에서 꼽으면 전류는 플러그핀(3)을 거쳐 핀홀더(4)의 압착부(5)를 통해 코드(2)의 심선(16)에 전달되어 기기로 흐르게 된다.When the user plugs the plug into the outlet, the electric current is transmitted to the core wire 16 of the cord 2 through the crimping portion 5 of the pin holder 4 via the plug pin 3 and flows to the device.

따라서 종래에는 핀홀더(4) 압착부 압착불량 및 몰딩불량 또는 소비자가 플러그를 콘센트에서 뽑을 때 플러그를 잡고 뽑지 않고 코드(2)를 잡고 뽑았을 때 핀홀더(4)에서 심선(6)이 빠져 나와 서로 단락되는 현상 및 소비자가 물이 젖은 손으로 플러그를 잡았을 때 심선(6)이 플러그본체(1)의 표면가까이 빠져나와 거의 붙어 있는 경우에는 감전을 당할 위험이 야기 되었다.Therefore, in the related art, the core wire 6 is pulled out from the pin holder 4 when the pin holder 4 is poorly crimped and poorly molded, or when the consumer pulls out the plug when the plug is unplugged. The short circuit with me and when the consumer grips the plug with wet hands causes the electric shock to occur when the core wire 6 comes close to the surface of the plug body 1 and is almost stuck.

이러한 종래의 문제점을 개선하여 본 고안에서는 단락방지용 핀을 핀홀더에 일체형으로 형성하였다.In order to improve such a conventional problem, in the present invention, a short circuit prevention pin is integrally formed with a pin holder.

이하 첨부도면에 의거 상세히 설명하면 다음과 같다.Hereinafter will be described in detail based on the accompanying drawings.

본 고안 플러그의 기술 구성은 첨부도면 제 2 도에서 보는 바와 같이 핀홀더(15)에 핀(13)이 나일론수지로 몰딩되어 있고, 핀폴더(15) 압착부(14)의 구멍에 심선(16)이 넣어져 프레스로 압착되어 있으며, 핀홀더(15) 및 코드(12)는 플러그본체(11)에 몰딩 형성하였다.As shown in FIG. 2, the pin 13 is molded into the pin holder 15 by nylon resin, and the core wire 16 is formed in the hole of the crimping portion 14 of the pin folder 15. As shown in FIG. ) Was pressed into a press, and the pin holder 15 and the cord 12 were molded in the plug body 11.

또한 단락 방지용 핀(17)을 핀홀더(15)에 일체형으로 형성하여서 된 것이다.In addition, the short-circuit prevention pin 17 is formed integrally with the pin holder 15.

상기와 같이 구성된 본 고안의 동작 설명은 사용자가 플러그를 콘센트에 꼽으면 전류는 플러그핀(13)를 거쳐 핀홀더 압착부(14)를 통해 코드(12)의 심선(16)에 전달되어 거기로 흐르게 된다.Description of the operation of the present invention configured as described above, when the user plugs the plug into the outlet, the current is transmitted to the core wire 16 of the cord 12 through the pin holder crimp 14 through the plug pin 13 to flow there. do.

이때 핀홀더(15) 압착불량 및 몰딩불량 등에 의해서 심선(16)이 밖으로 빠져 나왔을 때 일체형으로 형성된 핀홀더(15)의 단락 방지용 핀(17)에 의해서 차단하게된다.At this time, when the core wire 16 comes out of the pin holder 15 due to poor crimping and molding failure, it is blocked by the short-circuit preventing pin 17 of the pin holder 15 integrally formed.

그러므로 본 고안은 핀홀더(15)에 단락 방지용 핀(17)이 일체형으로 형성되어 핀홀더(15)의 압착불량 및 몰딩불량 등에 의해서 심선(16)이 밖으로 빠져나왔을 때 단락 방지용 핀(17)에 의해서 차단되어 단락되는 것을 방지되도록 되어 있다.Therefore, the present invention is formed in the pin holder 15, the short-circuit prevention pin 17 is integrally formed in the short-circuit prevention pin 17 when the core wire 16 is pulled out due to poor crimping and molding failure of the pin holder 15, etc. Is prevented from being blocked by a short circuit.

또한 소비자가 물이 젖은 손으로 플러그를 잡았을 때, 심선(16)이 플러그본체(11)의 표면 가까이서 거의 붙어 있는 현상도 방지되기 때문에 감전 당할 위험성도 적은 효과가 있다.In addition, when the consumer grasps the plug with wet hands, the core wire 16 is prevented from sticking close to the surface of the plug main body 11, thereby reducing the risk of electric shock.
