Description
본 고안은 사용중 안전성이 요구되는 선풍기형 히터, 전기스토브 및 인버터 스탠드 등과 같은 전기제품에 사용되는 안전스위치에 관한 것으로, 더 상세하게는 안전스위치의 단자구조를 개선하여 전선을 연결하기 위한 납땜 또는 잭 연결작업을 편리하게 수행하고, 또한 이를 통해 제품의 생산성을 향상시킬 수 있도록 한 안전스위치에 관한 것이다.The present invention relates to a safety switch used in electrical appliances such as a fan type heater, an electric stove and an inverter stand that require safety during use. More specifically, soldering or jacks for connecting electric wires by improving the terminal structure of the safety switch. The present invention relates to a safety switch that makes it easy to connect and improves the productivity of the product.
일반적으로 선풍기형 히터, 전기스토브, 인버터 스탠드 등과 같은 전기제품에는 제품 사용시 부주의로 인하여 전기제품이 넘어졌을 때 전기에너지의 공급을 차단하여 화재와 같은 2차 사고를 미연에 방지하기 위하여 안전스위치가 설치되고 있다.In general, electric appliances such as fan heaters, electric stoves, inverter stands, etc. are installed with safety switches to prevent secondary accidents such as fire by cutting off the supply of electric energy when electrical appliances fall down due to inadvertent use of the product. It is becoming.
이러한 안전스위치는 전기제품의 베이스 하부로 돌출되어지게 설치된 푸시봉이 바닥면에 의해 눌려 접지편을 접지단자에 접지시켜서 전기에너지를 통전시키게 된다.The safety switch is pushed by the bottom surface push bar is installed to protrude to the base of the electrical appliance to ground the ground piece to the ground terminal to energize the electrical energy.
상기 접지편과 접지단자의 접지로 공급되는 전기에너지를 이용하여 전기제품을 사용하게 되는데, 사용중 부주위로 인해 전기제품이 넘어질 경우, 안전스위치에 의해 전기에너지가 자동으로 차단되어 진다.An electric product is used by using the electric energy supplied to the grounding piece and the ground of the ground terminal. When the electric product falls down due to the sub surroundings during use, the electric energy is automatically cut off by the safety switch.
즉, 전기제품이 넘어지면 베이스 하부면으로부터 돌출되어서 바닥면에 눌려 있던 푸시봉이 자유로운 상태가 되어 접지편이 자체 탄성에 의해 접지단자로부터 이격되어 떨어진다.That is, when the electrical appliance falls down, the push rod, which protrudes from the bottom surface of the base and is pressed on the bottom surface, becomes free, and the ground piece is separated from the ground terminal by its elasticity.
이와 같이 전기제품이 넘어지면 접지편이 접지단자로부터 자동적으로 이격됨으로서 전기제품에 전기에너지의 공급이 차단되어지게 되고, 따라서 전기제품이 넘어져 발생될 수 있는 화재사고를 미연에 방지할 수 있는 것이다.As such, when the electrical appliance falls, the grounding piece is automatically spaced apart from the ground terminal, thereby blocking the supply of electrical energy to the electrical appliance, thereby preventing fire accidents that may occur due to the electrical appliance falling down.
상기와 같은 기능을 수행하는 종래의 안전스위치는 도 1 내지 도 3에 도시된 바와 같이, 하부가 개방된 공간부(1a)의 양측으로 접지단자(2)와 접지편(3)이 접촉가능하게 설치되고, 공간부(1a)의 각 모서리에 겹합공(1b)이 형성되며, 양측으로 나사공(1c)이 천공된 본체(1); 상기 결합공(1b)에 끼워지는 결합봉(4a) 및 나사공(1c)에 대응하는 나사공(4b)을 구비하여 본체(1)의 하부에 결합되고, 저면 일측으로 안내관(4c)이 돌출된 커버(4)와; 상기 커버(4)의 안내관(4c)에 스프링(5a) 탄력을 받도록 출몰가능하게 결합되고, 접지편(3)을 접지단자(2)에 접지시키는 작동봉(5b)이 구비된 푸시봉(5)을 포함하여 구성된다. 이때, 상기 접지단자(2)와 접지편(3)에 일체로 형성되어 외부로 돌출되는 전선연결단자(2a)(3a)는 본체(1)를 관통하여 수직상부로 돌출되고, 상기 연결단자(2a)(3a)에는 납땜 또는 잭을 통해 전선이 각각 연결된다.In the conventional safety switch that performs the above function, as shown in FIGS. 1 to 3, the ground terminal 2 and the grounding piece 3 are in contact with both sides of the space part 1a of which the lower part is open. A main body 1 installed and having overlapping holes 1b formed at respective corners of the space part 1a and having screw holes 1c drilled at both sides thereof; A coupling rod 4a fitted to the coupling hole 1b and a screw hole 4b corresponding to the screw hole 1c are coupled to the lower portion of the main body 1, and the guide tube 4c is disposed at one side of the bottom surface. A protruding cover 4; A push rod having a working rod 5b coupled to the guide tube 4c of the cover 4 so as to receive elasticity of the spring 5a and grounding the ground piece 3 to the ground terminal 2. 5) is configured to include. In this case, the wire connecting terminals 2a and 3a which are integrally formed on the ground terminal 2 and the ground piece 3 and protrude to the outside protrude upwardly through the main body 1, and the connecting terminal ( The wires are respectively connected to 2a) and 3a through soldering or a jack.
그러나, 이와 같이 구성된 종래의 안전스위치는 구조적으로 연결단자(2a)(3a)가 본체(1)의 수직상부로 돌출되기 때문에, 전선을 연결하기 위한 납땜 또는 잭의 연결작업이 매우 불편하여 작업성이 떨어지는 문제점이 있었으며, 또한 이로 인해 생산성이 저하되는 문제점이 있었다.However, in the conventional safety switch configured as described above, since the connecting terminals 2a and 3a protrude upwardly to the vertical part of the main body 1, the soldering or jacking work for connecting the electric wires is very inconvenient and workable. There was a problem falling, and there was also a problem that the productivity is lowered.
즉, 안전스위치의 조립시 먼저 안전스위치를 전기제품의 베이스에 나사조립으로 고정한 상태에서 연결단자(2a)(3a)에 납땜 또는 잭으로 전선을 연결하는 과정에서, 연결단자(2a)(3a)가 본체(1)의 수직상부로 돌출되어 본체(1)와 커버(4)에 의해 가려지고 또한 베이스와 연결단자(2a)(3a) 사이의 작업공간이 작기 때문에 납땜작업 또는 잭 연결작업이 매우 까다롭고 불편하여 작업성이 좋지 않은 문제점이 있었다.That is, when assembling the safety switch, in the process of connecting the wires by soldering or jacks to the connection terminals 2a and 3a while the safety switch is fixed by screw assembly to the base of the electrical appliance, the connection terminals 2a and 3a. Is protruded vertically to the upper part of the main body 1 and is covered by the main body 1 and the cover 4, and the working space between the base and the connecting terminals 2a and 3a is small. Difficult and uncomfortable there was a problem of poor workability.
또한 종래에는 안전스위치의 본체(1)와 커버(4)의 결합이 단순히 결합공(1b),결합봉(4a)을 통해 조립되었기 때문에, 구조적으로 유통과정에서 충격 등에 의해 쉽게 분리되는 문제점이 있었다.In addition, in the related art, since the coupling between the main body 1 and the cover 4 of the safety switch is simply assembled through the coupling hole 1b and the coupling rod 4a, there is a problem that the structure is easily separated by an impact during distribution. .
본 고안의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해 안출한 것으로, 사용중 안전성이 요구되는 선풍기형 히터, 전기스토브 및 인버터 스탠드 등과 같은 전기제품에 사용되는 안전스위치의 단자구조를 개선하여 전선을 연결하기 위한 납땜 또는 잭 연결작업을 편리하게 수행하고, 또한 이를 통해 제품의 생산성을 향상시킬 수 있도록 한 안전스위치를 제공하는데 있다.The object of the present invention is to solve the above-mentioned drawbacks as described above, by improving the terminal structure of the safety switch used in electrical appliances such as electric heaters, electric stoves and inverter stands that require safety during use, It is to provide a safety switch that can easily perform soldering or jacking work to connect the power supply, and thereby improve the productivity of the product.
본 고안의 또 다른 목적은 안전스위치의 결합구조를 개선하여 본체와 커버가 쉽게 분리되는 것을 방지할 수 있도록 한 안전스위치를 제공하는데 있다.Still another object of the present invention is to provide a safety switch that can prevent the main body and the cover from being easily separated by improving the coupling structure of the safety switch.
상기 목적을 달성하기 위해 본 고안은 본체의 전면 양측에 단자인출공을 각각 형성하되, 접지단자와 접지편에 단자인출공을 통해 외측으로 평탄하게 돌출되는 연결단자를 각각 일체로 형성한 것이다.In order to achieve the above object, the present invention is to form a terminal lead-out hole on both sides of the front of the main body, respectively, the ground terminal and the grounding piece is formed integrally with the connection terminal protruding outward through the terminal lead-out hole.
