옥내용 파워퓨즈의 단자봉 후렌지의 캐처Catcher of terminal rod Hurenji of indoor power fuse

제5도는 본 고안의 작동을 설명키 위한 설치상태 종단면도.Figure 5 is a longitudinal cross-sectional view of the installation state for explaining the operation of the present invention.

제6도는 본 고안의 작동후 단면도.6 is a cross-sectional view after the operation of the present invention.

본 고안은 퓨즈가 과전류에 의해 용단되어 압축 스프링에 의해 압축되어있던 단자봉이 돌출할때, 단자봉이돌출한 그 상태로 유지되게 하여 퓨즈의 용단 표식을 보다 확실하게 표시코자 하는 옥내용 파워퓨즈의 단자봉후렌지의 캐처에 관한 것이다.The present invention is a terminal of an indoor power fuse to display the fuse blowout mark more reliably so that when the fuse is blown by over current and the terminal rod compressed by the compression spring protrudes, the terminal rod remains in the protruding state. It is about catcher of bonhurenji.

종래에 퓨즈에 있어서는, 퓨즈가 용단되었을때 압축스프링에 의해 압축되어 있던 단자봉이 돌출되게는 되어있으나, 단자봉핀이 돌출된 그 상태로 유지되지 않고 반발되거나 후퇴되어 퓨즈용단표식이 확실하게 표시되지않으며 용단 낙하 표식등에 의한 연동작동을 행할수 없는 결함이 지적되고 있다.Conventionally, in fuses, when the fuse is blown, the terminal rod compressed by the compression spring is protruded, but the terminal bar pin does not remain in the protruding state, but is repelled or retracted so that the fuse mark is not clearly displayed. The defect which cannot carry out interlocking operation by the blowdown fall-mark etc. is pointed out.

본 고안은 종래의 결함을 해소하고, 보다 확실한 퓨즈용단표식을 하기 위한 것으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to solve the conventional defects, and to make a more reliable fuse short marker, which will be described in detail by the accompanying drawings as follows.

외주면에 수개의 저지편(1')을 펀칭하여 내측으로 절곡시킨 원통형 캐처 본체(1)를 퓨즈(F)선단의 동판(2)내측에 형성시킨 돌턱(2')이 장착하되, 상기 저지편(1')의 끝단이 동관(2)외측에 형성시킨 밀폐구(3)의 박판(3')측으로 향하도록 설치한다.On the outer circumferential surface, a stone catcher 2 'is formed in which the cylindrical catcher main body 1, which is punched inward by bending several blocking pieces 1', is formed inside the copper plate 2 at the tip of the fuse F. It is provided so that the end of (1 ') faces the thin plate (3') side of the sealing opening (3) formed outside the copper pipe (2).

상기 밀폐구(3)는 동관(2)의 절곡부(2")에 의해 지지된다.The closure 3 is supported by the bent portion 2 "of the copper tube 2.

일반적으로 특별고압퓨즈(F)는 동관(2) 외주면에 절연체(20)를 압착형성하고, 단자봉(21)후단에 가용선(22)과 인장선(23)이 용착되어 있으며, 단자봉(21)의 선단은 접속두부(24)로 형성되어 있고 접속두부(24)는 가동접점(25)과 후렌지(26), 핀(27)으로 구성되어 있다. 그리고, 후렌지(26)의 하방과 고정접점 후렌지(28)사이에 압축 스프링(29)이 압축되어 있다.In general, the special high-pressure fuse (F) is formed by crimping the insulator 20 on the outer circumferential surface of the copper tube (2), the soluble wire 22 and the tension wire (23) is welded to the rear end of the terminal rod 21, the terminal rod ( The tip of 21 is formed by a connecting head 24, and the connecting head 24 is composed of a movable contact 25, a flange 26, and a pin 27. The compression spring 29 is compressed between the lower side of the flange 26 and the fixed contact flange 28.

도면중 미설명 부호, 30은 결속스프링, 31은 고정접점, 32는 개별접점, 33은 원통형 조립품 소호재, 34는 배출금구, 35는 하부단자, F'는 퓨즈(F)의 선단부, P는 파워퓨즈의 전체를 나타낸다.In the drawings, reference numeral 30 denotes a binding spring, 31 a fixed contact, 32 an individual contact, 33 a cylindrical assembly extinguishing material, 34 a discharge port, 35 a lower terminal, F 'is a leading end of a fuse (F), and P is It shows the whole power fuse.

이상과 같이 구성된 본 고안의 작용효과는 다음과 같다.Effects of the present invention configured as described above are as follows.

퓨즈(F)에 과전류가 흐르면, 가용선(22)과 인장선(23)이 용단하게 되며, 단자봉(21)의 선단에 형성된 접속두부(24)는 압축 스프링(29)에 의해 순간적으로 박판(3')을 향해 튕겨나가게 된다.When an overcurrent flows through the fuse F, the soluble wire 22 and the tension wire 23 are melted, and the connecting head 24 formed at the tip of the terminal rod 21 is instantaneously thinned by the compression spring 29. It will bounce off to (3 ').

이와같이 튕겨나가는 접속두부(24)의 선단에 형성된 핀(27)이 박판(3')을 타격하면서 관통 돌출하게 됨과 동시후렌지(26)의 외주면이 캐처 본체(1)의 지지편(1')을 외측으로 밀면서 지지편(1')을 지나치게 된다.In this way, the pin 27 formed at the tip of the jumping head 24 is projected through the thin plate 3 'while the outer peripheral surface of the flange 26 is supported by the support piece 1' of the catcher main body 1 '. While pushing outward, the support piece 1 'becomes excessive.

이때, 지지편(1)은 자체 복귀력에 의해 원상복귀되어 제6도와 같이 후렌지(26)하방에 위치하게 되므로후렌지(26)가 반발되지 않고 돌출된 그상태로 유지하게되어 퓨즈(F)의 용단을 표시하게 되는 것이다.At this time, since the support piece 1 is returned to its original state by its return force and is positioned below the flange 26 as shown in FIG. 6, the flange 26 is not repulsed and maintained in the protruding state so that the fuse F of the fuse F It will mark the dissolution.

이상과 같이 본 고안은 퓨즈의 용단시 단자봉의 후렌치 및 핀이 돌출된 그 상태로 유지되도록 하므로서 퓨즈의 용단이 확실하게 표식될수 있는 유용하고도 실용적인 고안이다.As described above, the present invention is a useful and practical design to ensure that the fuse of the terminal can be reliably marked while keeping the flange and pin of the terminal rod protruding when the fuse is blown.
