본 고안은 회로차단기에 관한 것으로서, 특히 그 단자부를 보호하여 충전부(充電部)에 접촉하지 않도록하기 위한 단자카바에 있어서, 그 장착 및 봉인구조의 개량에 관한 것이다.The present invention relates to a circuit breaker, and more particularly, to a terminal cover for protecting the terminal portion so as not to come into contact with the charging portion, and to the improvement of its mounting and sealing structure.
종래 이와같은 종류의 회로차단기의 단자카바로서 제1도에 표시한 것 등이 있었다.Conventionally, the terminal cover of this type of circuit breaker has been shown in FIG.
도면에 있어서, 1은 회로차단기본체의 케이스, 3는 충전부를 덮는 단자카바, 2a는 위의 단자카바(2)에 설치된 돌기. 3은 단자카바(2)를 케이스(1)에 고정시키는 취부나사, 4는 단자카바(2)를 케이스(1)에 고정 및 봉인을 겸한 봉인나사, 5는 봉인선으로서 단자카바(2)의 돌기(2A)와 봉인나사(4)를 연결하여 봉인한다.In the drawings, 1 is a casing of a circuit blocking main body, 3 is a terminal cover covering a live part, and 2a is a protrusion provided on the terminal cover 2 above. 3 is a mounting screw for fixing the terminal cover 2 to the case 1, 4 is a sealing screw for fixing and sealing the terminal cover 2 to the case 1, and 5 is a sealing line of the terminal cover 2 as a sealing line. The protrusion 2A and the sealing screw 4 are connected and sealed.
종래의 회로차단기의 단자카바는 위와같이 구성되어 있으므로, 단자카바(2)를 취부나사(3) 및 봉인나사(4)로서 케이스(1)에 취부할 경우, 합성수지로 형성된 케이스 (1)에 취부나사(3) 및 봉인나사(4)에 나합하는 너트를 매설하든가 또는 케이스(1)에 나사를 직접 형성하든가 해서 만들었다.Since the terminal cover of the conventional circuit breaker is configured as above, when the terminal cover 2 is attached to the case 1 as the mounting screw 3 and the sealing screw 4, it is attached to the case 1 formed of synthetic resin. It was made by embedding a nut screwed into the screw 3 and the sealing screw 4 or by directly forming the screw in the case 1.
이와같이 구성된 것에 있어서, 전자는 케이스(1)를 성형하는데 가격이 많이 소요되고, 후자는 케이스(1)의 강도가 약하므로 여러번 반복하여 취부하므로 인해 내부에 형성된 나사가 파괴되는 결점 등이 있었다. 또한 단자카바(2)를 착탈할 때 취부나사(3) 및 봉인나사(4)를 착탈하지 않으면 안되므로 번거로운 결점 등이 있었다.In this configuration, the former is expensive to mold the case 1, the latter is weak because the strength of the case 1 is repeatedly attached several times, there is a defect that the screw formed therein. In addition, when the terminal cover 2 is attached and detached, the mounting screw 3 and the sealing screw 4 must be attached and detached, which causes cumbersome defects.
본 고안은 위와같은 결점등을 제거하기 위해 안출된 것으로서, 단자카바의 착탈 및 봉인작업을 즉석에서 시행할 수 있는 회로차단기를 제공하는데 그 목적이 있다.The present invention has been made to remove the above-mentioned defects, the purpose is to provide a circuit breaker that can be carried out immediately to remove and seal the terminal cover.
본 고안의 한 실시예를 제2도 내지 제7도에 의해 설명한다.An embodiment of the present invention will be described with reference to FIGS. 2 to 7.
도면에서 1은 회로차단기 본체의 케이스로서, 카바(1A)와 베이스(1B)로 형성되어 있다.In the figure, 1 is a case of the circuit breaker main body, and is formed of the cover 1A and the base 1B.
1C, 1D는 카바(1A)와 베이스(1B)에 개구되어 회로차단기 본체를 취부 패널 (Panel)(7)에 취부되는 보울트(8)이 삽입된 삽입공인데, 한쪽의 삽입공(1C)의 상부에는 단부(1E)를 갖고 있다.1C and 1D are insertion holes into which the bolt 8 which is opened in the cover 1A and the base 1B and is mounted on the panel 7 to the circuit breaker main body is inserted. The upper portion has an end 1E.
1F는 케이스(1)의 외측으로 노출되게 장설된 단자부, 2는 절연재로 되고 단자부(1F)를 덮은 단자카바인데. 그 내측에는 삽입공(1C)의 상단부에 감삽되는 변곡가능(變曲可能)한 U자형 돌기부(2C)가 돌설되어 있다. 그리고 이 돌기부(2C)의 계합편(2F)에는 단부(1E)와 계합하는 계합부(2E)가 장설되어 있다.1F is a terminal part installed to be exposed to the outside of the case 1, and 2 is a terminal cover made of an insulating material and covering the terminal part 1F. Inside thereof, an inflectable U-shaped protrusion 2C is inserted into the upper end of the insertion hole 1C. And the engaging part 2E engaging with the edge part 1E is provided in the engaging piece 2F of this projection part 2C.
2D는 단자카바(2)에 돌기부(2C)와 거의 평행으로 돌설된 다른 쪽의 삽입공 (1D)에 감삽되는 돌출봉, 2A는 단자카바(2)의 일부표면에 돌설되고, 봉인공(2B)을 가진 돌출부, 6은 돌기부(2C)에 형성된 U형구(2G)내에 감합되는 봉인판으로서, 상단부에 봉인공(6A)을 갖고 있다. 5는 양봉인공(2B),(6A)에 삽입되는 봉인선이다.2D is a protruding rod that is inserted into the other insertion hole 1D protruding substantially parallel to the projection 2C on the terminal cover 2, 2A is protruded on a part surface of the terminal cover 2, and the sealing hole 2B Is a sealing plate fitted into the U-shaped sphere 2G formed in the projection 2C, and has a sealing hole 6A at its upper end. 5 is a sealing line inserted in beekeeping artificial 2B and 6A.
이와같은 구성에 있어서, 단자카바(2)를 케이스(1)에 취부할 경우, 단자카바 (2)에 설치된 돌기부(2C)와 돌출봉(2D)을 케이스(1)에 설치되어 있는 삽입용공(1C), (1O)에 각각 삽입하면, U자형으로 형성된 돌기부(2C)는 계합편(2F)의 휘어짐에 의하여 일정장소까지 삽입되므로 계합부(2E)가 삽입용공(1C)에 설치되어 있는 단부(1E)에 계합하게 된다.In such a configuration, when the terminal cover 2 is attached to the case 1, an insertion hole in which the protrusion 2C and the protruding rod 2D provided on the terminal cover 2 is provided in the case 1 ( 1C) and 10O, respectively, the U-shaped projection 2C is inserted to a certain place by the bending of the engaging piece 2F, so that the engaging portion 2E is provided at the insertion hole 1C. To (1E).
제6도 및 제7도에 표시되어 있는 바와같이 봉인편(6)을 단자카바(2)의 표면에서 U자구(2G)내에 삽입한 후 봉인선(5)을 봉인편(6)에 형성된 봉인공(6A)과 단자카하(2)의 표면에 설치된 돌출부(2A)의 봉인공(2B)에 통과시킴으로써 봉인할 수 있어, 봉인선(5)을 절취하지 않는한 단자카바(2)를 제거할 수 없다. 또한 단자카바(2)를 제거할 경우에는, 우선 봉인선(5)을 절취한 후 봉인편(6)을 U자구(2G)에서 뽑아내기 전에 단자카바(2)의 돌기부(2C)의 계합편(2F)을 외측에서 화살표 B방향으로 휘어지게 하여 계합부(2E)와 단부(1E)의 계합을 해제시킴으로써, 단자카바(2)를 제거할 수 있는 것이고, 단자카바(2)의 착탈 및 봉인작업을 간단하고 용이하게 할 수 있는 것이다.As shown in FIGS. 6 and 7, the sealing piece 6 is inserted into the U-shaped sphere 2G on the surface of the terminal cover 2, and then the sealing line 5 is formed on the sealing piece 6. It can be sealed by passing through the sealing hole 2B of the projection 2A provided on the surface of the artificial 6A and the terminal cover 2, and the terminal cover 2 can be removed unless the sealing line 5 is cut off. Can't. When the terminal cover 2 is removed, first, the sealing line 5 is cut off and then the engaging piece of the projection 2C of the terminal cover 2 is removed before the sealing piece 6 is pulled out of the U-shaped sphere 2G. The terminal cover 2 can be removed by releasing the engagement between the engaging portion 2E and the end portion 1E by bending the 2F in the direction of arrow B from the outside, and detaching and sealing the terminal cover 2. The job is simple and easy.
위에서 설명한 바와 같이 본고안은 단자카바의 착탈 및 봉인작업이 간단하고 용이할 뿐만 아니라 기히 설치된 보울트의 삽입용공을 사용하게되므로 케이스의 상형이 간소화되어 염가한 회로차단기를 제공할 수 있다.As described above, the present invention is simple and easy to remove and seal the terminal cover, as well as the use of the insertion hole of the bolt already installed can simplify the top of the case can provide a cheap circuit breaker.
