In addition, the present invention relates to a power plug having a fuse that can prevent a fire caused by heating of the power plug.
종래에는 각종 전자제품에 제품의 안전을 위하여 퓨즈를 내장함으로서 제품에 갑작스런 과전류가 발생하는 경우 상기 퓨즈가 단락되어 각종 전자제품을 안전하게 보호할수 있도록 하였으나, 이는 퓨즈가 제품내에 설치됨으로서 단락된 퓨즈를 교체하기 위해서는 전자제품을 일일이 분해해야되는 불편이 있었다.Conventionally, in the case of a sudden overcurrent generated in a product by incorporating a fuse for the safety of the product in various electronic products, the fuse is short-circuited to safely protect various electronic products. However, the fuse is installed in the product to replace the shorted fuse. In order to disassemble electronic products, there was an inconvenience.
이를 감안하여 본 출원인에 의하여 퓨즈가 구비된 전원플러그(실용신안등록제166003호)가 개발되어 전원플러그의 전원접지봉에 과전류를 차단할수 있는 퓨즈가 내장된 구성으로 전자제품을 과전류로부터 효과적으로 보호할수 있게 되었고 단락된 퓨즈의 교체도 용이하게 할수 있었으나, 전원플러그가 접촉부위의 접촉저항등에 의해 비정상적으로 가열되는 고온발생으로 화재가 발생하는 것은 차단할수 없었다.In consideration of this, the present inventors have developed a power plug (utility model registration No. 166003) equipped with a fuse to effectively protect electronic products from overcurrent with a built-in fuse that can block overcurrent in the power grounding rod of the power plug. The shorted fuse could be easily replaced, but the fire could not be blocked due to the high temperature that the power plug was abnormally heated by the contact resistance of the contact portion.
본 고안은 이러한 문제점을 해결하기 위하여 전원플러그에 결합및 분리가능한 전원접지봉을 구비하고 그 전원접지봉에 퓨즈를 내장하되 전자제품에 인가되는 과전류 및 전원플러그 자체의 고온발생을 차단할수 있는 퓨즈가 구비된 전원플러그를 제공함에 있다.The present invention is provided with a power grounding rod that can be coupled and detached to the power plug in order to solve this problem, and the fuse is embedded in the power grounding rod, but is provided with a fuse that can block the over-current applied to the electronic products and the high temperature generation of the power plug itself In providing a power plug.
본 고안은 플러그몸체에 분리결합할 수 있게 구성된 전원접지봉과, 상기 전원접지봉내에 과전류 및 고온발생을 차단하는 퓨즈로 이루어진 전원플러그로 구성된다.The present invention consists of a power supply grounding rod configured to be separated and coupled to the plug body, and a power plug consisting of a fuse to block the occurrence of overcurrent and high temperature in the power grounding rod.
이하 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
플러그몸체(10)와 전원접지봉(20)(20')을 구비하는 통상의 전원플러그에 있어서, 상기 플러그몸체(10)의 결속구(14)에 외측을 향하도록 나선홀(14a)을 형성하여 원통형의 전원접지봉(20)을 결합하고, 후단에는 전선(30)이 결속된 전선접속단자(32)을 연결하며, 결속구(14)에 결합되는 전원접지봉(20)은 퓨즈(28)가 내장된 부도체 연결구(26)의 선,후단에 전도체로 된 선,후단캡(22)(24)으로 결속되고 후단캡(24)은 결속구(14)와의 나사결합을 위한 나선부(24a)가 일체로 형성된다.In a typical power plug having a plug body 10 and a power grounding rod 20, 20 ', a spiral hole 14a is formed in the binding hole 14 of the plug body 10 to face outward. Combine the cylindrical power supply ground rod 20, the rear end is connected to the wire connection terminal 32, the wire 30 is bound, the power supply ground rod 20 is coupled to the binding hole 14 fuse 28 is built-in Wires of the insulated conductors 26, the wires of which are conductors at the rear end, and the rear end caps 22, 24 are bound together, and the rear end cap 24 has a spiral portion 24a for screwing with the binding holes 14. Is formed.
상기의 퓨즈(28)는 전자제품에 인가되는 과전류 및 전원플러그 자체가 비정상적으로 가열되어 고온발생하는 경우에 단락되는 전류퓨즈및 온도퓨즈로 이루어진 퓨즈소자로 구성되며 그 퓨즈소자는 구리, 금, 은, 니켈, 알루미늄, 주석으로 부터 선택된 금속 또는 이들의 합금으로 이루어진 전류퓨즈금속재료가 심선(28a)으로 구성되고 그 심선(28a)에 주석, 비스무스, 인듐, 납으로 부터 선택된 금속또는 이들의 합금으로 이루어져서 낮은 용융점을 갖는 온도퓨즈금속재료가 도금층(28b)으로 형성된 것이다.The fuse 28 is composed of a fuse device consisting of a current fuse and a temperature fuse that is short-circuited when an overcurrent applied to the electronic device and the power plug itself are abnormally heated to generate a high temperature, and the fuse device includes copper, gold, and silver. , A current fuse metal material composed of a metal selected from nickel, aluminum, tin, or an alloy thereof is composed of a core wire 28a, and the core wire 28a is a metal selected from tin, bismuth, indium, lead, or an alloy thereof. The heat fuse metal material having a low melting point is formed of the plating layer 28b.
그리고 플러그몸체(10)의 중앙을 관통하여 예비퓨즈홀(12)이 형성되어 여분의 예비퓨즈를 보관하기 위해 전원접지봉(20)을 삽입보관하도록 되어 있다.Then, a preliminary fuse hole 12 is formed through the center of the plug body 10 to insert and store the power grounding rod 20 to store the extra preliminary fuse.
이와같은 본 고안의 작용에 대하여 설명하면 다음과 같다.Referring to the operation of the present invention as follows.
플러그를 구성하는 플러그몸체(10)의 결속구(14)에 나선홀(14a)이 형성되어 있고 퓨즈(28)가 내장된 전원접지봉(20)의 후단캡(24)에는 상기 결속구(14)에 나사결합되는 나선부(24a)가 형성되어 있어 이들을 나사결합하면 통상의 전원플러그가 구성되므로 이러한 플러그몸체(10)를 콘센트에 접속시키면 콘센트의 전원이 플러그몸체를 통하여 전자제품에 통전이 이루어진다.The binding hole 14 is formed in the rear end cap 24 of the power grounding rod 20 in which the spiral hole 14a is formed in the binding hole 14 of the plug body 10 constituting the plug and the fuse 28 is incorporated. Screws are formed in the spiral portion (24a) is formed by screwing them together so that the normal power plug is configured, so when the plug body 10 is connected to the outlet, the power of the outlet is energized through the plug body to the electronics.
이때 전자제품에서 비정상적인 과전류가 인가되면 전원접지봉(20)의 퓨즈(28)가 단락되어 전원을 차단하는 수단으로 전자제품을 보호하게 된다.At this time, if an abnormal overcurrent is applied from the electronic product, the fuse 28 of the power supply ground rod 20 is short-circuited to protect the electronic product as a means of cutting off the power.
또한, 전원플러그가 비정상적인 가열에 의해 고온이 발생하는 경우에 전원접지봉(20)의 퓨즈가 단락되어 전원플러그의 접촉저항등에 의한 고온발생을 차단하는 수단으로 전원플러그 과열에 의한 화재발생을 방지하게 된다.In addition, when a high temperature occurs due to abnormal heating of the power plug, the fuse of the power grounding rod 20 is short-circuited to prevent high temperature caused by contact resistance of the power plug, thereby preventing fire from overheating of the power plug. .
즉, 본 고안의 전원접지봉(20)에 구비된 퓨즈(28)는 전류퓨즈와 온도퓨즈를 함께 갖는 퓨즈소자로 구비되어 과전류발생시에는 심선(28a)에 구비된 전류퓨즈가 먼저 용융된 다음 도금층(28b)의 온도퓨즈가 용융되는 수단으로 단락되고, 과열온도가 발생하는 경우에는 도금층(28b)의 온도퓨즈가 먼저 용융된 다음 심선(28a)의 전류퓨즈가 용융되는 수단으로 단락되어 전자제품에 인가되는 과전류뿐만 아니라 전원플러그가 접촉불량등에 의한 접촉저항등으로 고온으로 가열되는 것을 차단하게 된다.That is, the fuse 28 provided in the power supply ground rod 20 of the present invention is provided as a fuse device having a current fuse and a temperature fuse together, and when an overcurrent occurs, the current fuse provided in the core wire 28a is first melted, and then the plating layer ( The temperature fuse of 28b) is short-circuited by means of melting, and when an overheating temperature occurs, the temperature fuse of the plating layer 28b is first melted and then the current fuse of the core wire 28a is short-circuited and applied to the electronic product. In addition to the overcurrent, the power plug is blocked from being heated to high temperatures due to contact resistance caused by poor contact.
그리고 본원 고안의 전원접지봉(20)에 구비된 퓨즈(28)가 단락된 상태에서 전자제품에 인가되는 과전류 및 전원플러그 자체가 고온발생하게 된 원인을 해결한 다음 플러그몸체(10)에 결합되는 전원접지봉(20)을 분리하여 교체사용하면 된다.And the power supply coupled to the plug body 10 to solve the cause of the high current generated in the overcurrent and the power plug itself applied to the electronic products in the short circuited state of the fuse 28 provided in the power supply ground rod 20 of the present invention The ground rod 20 can be removed and replaced.
이와같이 본 고안의 퓨즈가 구비된 전원플러그는 플러그몸체에 퓨즈가 구비된 전원접지봉을 설치하여 평상시에는 접속플러그로서 사용하고 전원플러그에 의해 통전되는 전자제품에서 과전류가 인가되는 경우에는 퓨즈가 단락되어 전자제품을 보호하는 기능을 수행하게 될뿐만 아니라 전원플러그가 접촉저항등에 가열되어 야기되는 고온에 의해 화재가 발생하는 것을 방지할수 있는 이점이 있다.In this way, the power plug with a fuse of the present invention has a power grounding rod equipped with a fuse in the plug body, which is normally used as a connection plug, and when an overcurrent is applied from an electronic product energized by the power plug, the fuse is short-circuited. Not only does it protect the product, it also has the advantage of preventing fire from being caused by the high temperature caused by the power plug being heated by contact resistance.
그리고 이러한 전자제품에 인가되는 과전류 및 전원플러그의 고온발생을 하단하는 퓨즈가 플러그몸체에 쉽게 분리결합할 수 있도록 한 전원접지봉에 구비되어 사용이 편리한 이점이 있다.And there is an advantage that the fuse is provided on the power supply ground rod that can be easily separated and coupled to the plug body overcurrent and high-temperature generation of the power plug applied to these electronic products has an advantage.
