본 고안은 열 흡수형 퓨우즈에 관한 것으로, 엘레멘트에 스프링과 납으로 형성된 열흡수부를 연결하여 엘레멘트의 열화를 방지토록 설치한 것이다.The present invention relates to a heat absorbing fuse, it is installed to prevent the deterioration of the element by connecting the heat absorbing portion formed of the spring and lead to the element.
종래의 일반적인 퓨우즈는 도면 제2도에서와 같이 유리관 양측에 캡이 형성되고 내부에는 은과 동으로 합금된 엘레멘트로 연결하여 사용하였으나, 엘레멘트는 열전도량이 작으므로 단시간내에 심한 파형의 변화를 일으키는 서어지(surge)전류에 의한 큰 열량을 담당치 못하여 엘레멘트가 열화되어 절단되거나, 절단되지 않을 경우에는 열화의 누적으로 기능이 정상적으로 유지되지 못하는 결점이 있었던 것이며, 특히 냉장고에 있어서는 과부하 보호기기로 퓨우즈를 반듯이 사용하나 냉장고 자체의 잦은 단속기동으로 기동서어지 전류에 의한 퓨우즈가 그 기능을 상실하게 되어 제품의 신뢰도를 저하시키는 문제점이 있었던 것이다.Conventional fuses are used in the form of a cap formed on both sides of the glass tube as shown in Figure 2 and connected by an alloy alloyed with silver and copper inside, but the element is a thermal wave that causes a severe waveform change in a short time due to the small amount of thermal conductivity If the element is deteriorated due to a large amount of heat due to surge current, or if the element is deformed or not cut, there is a defect in that the function cannot be maintained normally due to accumulation of deterioration. However, due to frequent intermittent startup of the refrigerator itself, the fuse due to the surge current lost its function, which lowered the reliability of the product.
본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로, 유리관 양측은 캡이 형성된 퓨우즈에 있어서, 퓨우즈 내부에 연결된 엘레멘트의 일측을 납으로된 열흡수부와 스프링을 연결설치하여 엘레멘트의 열화를 방지하고, 스프링의 복원력으로 에레멘트를 분리시켜 과전류를 차단되게한 열흡수형 퓨우즈를 제공하는 것이다.The present invention has been made in view of the above problems, both sides of the glass tube in the fuse having a cap, one side of the element connected to the inside of the fuse by connecting the heat absorbing portion and the spring with lead to prevent the element deterioration It is to provide a heat-absorbing fuse that prevents, by separating the element by the restoring force of the spring to block the overcurrent.
이를 첨부된 도면에 의하여 설명하면 다음과 같다.This will be described with reference to the accompanying drawings.
도면 제1도에서와 같이, 유리관(1)의 양측에 캡(2)(2')이 형성된 퓨우즈 본체(3) 내부에 엘레멘트(4)의 일측을 납으로 형성된 열흡수부(5)와 스프링(6)을 연결설치하여 엘레멘트(4)의 열화를 방지하게 한 것이며, 과전류시 납으로된 열흡수부(5)가 녹아 스프링(6)의 탄성 복원력으로 엘레멘트(4)와 분리되게 설치한 것이다.As shown in FIG. 1, the heat absorbing portion 5 having one side of the element 4 formed of lead in the fuse body 3 having the caps 2 and 2 'formed on both sides of the glass tube 1, and The spring 6 is connected and installed to prevent deterioration of the element 4, and the heat absorbing part 5 made of lead melts during overcurrent and is separated from the element 4 by the elastic restoring force of the spring 6. will be.
상기와 같이된 본 고안의 작용효과를 상술하면, 도면 제1도에서와 같이 캡(2)(2')과 유리관(1)으로 형성된 퓨우즈본체(3)의 내부에 스프링(6)과 열흡수부(5)를 연결한 엘레멘트(4)가 형성되어 있어, 통상적으로 도선에 흐르는 전류에 의하여 발생된 주울열이 엘레멘트(4)를 통하여 캡(2)(2')에 전도되었던 것이, 납으로 형성된 열흡수부(5)에 의하여 전류에 의한 열량이 흡수되는 것이다.Referring to the operation and effect of the present invention as described above, as shown in FIG. 1, the cap 6 and the heat inside the fuse body 3 formed of the glass tube 1 and the spring 6 and heat An element 4 connecting the absorber 5 is formed, so that Joule heat generated by the current flowing through the conductive wire is normally conducted to the cap 2, 2 ′ through the element 4. The amount of heat due to the current is absorbed by the heat absorber 5 formed as a result.
따라서, 일반적인 냉장고와 같은 과부하 보호기기에서는 잦은 서어지 전류에 의하여 퓨우즈본체(3)에 전류의 흐름이 자주 변하게 되어 쉽게 끊어지거나, 엘레멘트(4)가 열화되어 그 기능을 담당치 못하였던 것을 엘레멘트(4)에 형성한 열흡수부(5)가 충분하게 전도열량을 흡수 제거시켜 주므로 엘레멘트(4)의 열화를 방지시켜주는 것이다.Therefore, in an overload protection device such as a refrigerator, the current flows frequently in the fuse body 3 due to frequent surge current, and thus is easily broken, or the element 4 is deteriorated so that the element cannot perform its function. The heat absorbing portion 5 formed in (4) sufficiently absorbs and removes the heat of conduction, thereby preventing deterioration of the element 4.
또한, 과전류시 납으로된 열흡수부(5)는 제한된 납의 용융점에서 절단되므로 스프링(6)의 탄성복원력과 함께 엘레멘트(4)와 열흡수부(5)는 탄성있게 차단되어 과전류에 의한 퓨우즈의 안정성을 크게 높여 주는 유용한 고안인 것이다.In addition, since the heat absorbing portion 5 made of lead at the time of overcurrent is cut at the limited melting point of lead, the element 4 and the heat absorbing portion 5 are elastically blocked together with the elastic restoring force of the spring 6 to fuse by overcurrent. It is a useful design that greatly increases the stability of the.
