보강된 구조를 갖는 단자대{TERMINAL BLOCK WITH ENHANCED STRUCTURE}Terminal block with reinforced structure {TERMINAL BLOCK WITH ENHANCED STRUCTURE}

본 발명은 보강된 구조를 갖는 단자대에 관한 것으로서, 보다 구체적으로는 건물 내 저압 배전반의 단말부에 설치됨에 따라 전기 내선공사로 이어지는 전력케이블과의 접속을 용이하게 하기 위한 보강된 구조를 갖는 단자대에 관한 것이다.The present invention relates to a terminal block having a reinforced structure, and more particularly, to a terminal block having a reinforced structure for facilitating connection with a power cable leading to electrical extension work as installed in a terminal part of a low voltage switchgear in a building. It is about.

일반적으로 관공서, 학교, 빌딩 등에서는 비교적 많은 전기 사용량이 요구되므로 이에 따라 필수적인 구성요소로 수배전 설비가 설치되는데, 이러한 설비에 설치되는 기자재 중 저압 배전반 또는 이와 유사한 전기장치의 단말부에 설치하여 전기 내선공사로 이어지는 전력케이블을 접속하는 용도로 사용되는 것이 단자대이다. 다시 말해서, 단자대는 다수개의 누전차단기 또는 배선용 차단기의 일단측과 외부로 배분되는 전선의 타단측을 연결하여 접속하기 위한 것이다.In general, government offices, schools, buildings, etc. require a relatively large amount of electricity, and thus water distribution equipment is installed as an essential component. Among the equipment installed in these facilities, it is installed at the terminal of a low voltage switchgear or similar electrical equipment. Terminal blocks are used to connect power cables leading to extension works. In other words, the terminal block is for connecting and connecting one end side of a plurality of earth leakage breakers or wiring breakers and the other end side of an electric wire distributed to the outside.

그러나 기존의 단자대 제품의 정격 사양은 MCCB(Mold Case Circuit Braker)의 규격과 다소 상이하게 제작됨에 따라 MCCB와 단자대를 연결할 경우에 그 피치가 서로 맞지 않아 MCCB와 단자대 간을 일직선화 하기 어렵기 때문에, 부스바 연결 시 휨이 발생하게 되므로 작업의 완성도 및 미관이 떨어지게 된다. 또한 전원공급용 전력케이블을 연결하는 2차 접속단자부에는 표준화 제품으로 생산되는 1홀형 또는 2홀형 압착단자를 접속해야 하는데 기존의 단자대는 1홀형 압착단자만 접속할 수 있거나 규격이 작은 2홀형 압착단자만 접속할 수 있는 조건에 한정하고 있으므로 전류 정격에 미달되는 불리한 점과 별도의 접속편을 제작하여 설치해야하는 문제점이 있다.However, the rated specifications of the existing terminal block products are made somewhat different from the specifications of MCCB (Mold Case Circuit Braker), so when the connection between the MCCB and the terminal block does not match the pitch, it is difficult to straighten between the MCCB and the terminal block. When the busbars are connected, warpage occurs, which leads to a lack of completeness and aesthetics. In addition, it is necessary to connect 1-hole type or 2-hole type crimp terminal produced as a standardized product to the secondary connection terminal that connects the power cable for power supply. Existing terminal block can only connect 1-hole type crimp terminal or small 2-hole type crimp terminal Since it is limited to the conditions that can be connected, there are disadvantages that fall below the current rating and there is a problem that a separate connection piece must be manufactured and installed.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위해 안출된 것으로서, 전류용량이 큰 전력케이블의 굵기에 맞는 단자를 무리 없이 접속할 수 있도록 하는 보강된 구조를 갖는 단자대를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, and an object of the present invention is to provide a terminal block having a reinforced structure that can be connected without difficulty connecting the terminal of the power cable having a large current capacity.

또한 배전반 제작 시 제작 표준화를 연출하여 공정이 빠르게 진행될 수 있으며, 직선 연결공법을 이용함으로써 도체의 절감은 물론 외관상 미려함 또한 강조할 수 있는 보강된 구조를 갖는 단자대를 제공하는데 그 목적이 있다.In addition, the production process of the switchboard can be produced by directing the standardization process, and the purpose of providing a terminal block having a reinforced structure that can emphasize the appearance of the conductor as well as the reduction of the conductor by using a straight connection method.

한편으로 연결부의 절연구조를 강화함으로써 도전부의 노출로 인한 인명피해의 위험을 방지하는데 그 목적이 있다.On the other hand, the purpose is to prevent the risk of injury due to exposure of the conductive portion by strengthening the insulating structure of the connection portion.

It is composed of a plurality of vertical parts for dividing the upper surface at regular intervals as it extends, the upper portion of the trunk portion divided by the vertical portion is embedded with a nut for fixing one end of the busbar or power cable with a first bolt An indentation groove is formed in which a fixing hole and one end of the bus bar are fitted, and a through hole in which a second bolt penetrates from an upper surface of the vertical portion to a lower surface of the trunk portion is formed.

또한 상기 몸통부의 밀착홈 양측에는 상기 부스바의 일측 끝단과 상하로 겹쳐지는 복수개의 상기 전력케이블이 돌출되지 않도록 하는 간섭방지홈이 형성되고, 상기 수직부 양측에는 하측 방향을 따라 삽입홈이 형성되고, 상기 삽입홈에 끼움되는 돌출부가 내측으로 형성되어 복수개의 상기 수직부에 결합되는 투명커버가 더 포함되는 것을 특징으로 한다.In addition, an interference preventing groove is formed on both sides of the close contact grooves of the body to prevent the plurality of power cables overlapping one end of the bus bar from protruding, and insertion grooves are formed along both sides of the vertical portion. And a transparent cover which is formed inwardly to be inserted into the insertion groove and coupled to the plurality of vertical parts.

상술된 바와 같이, 본 발명에 따른 보강된 구조를 갖는 단자대는 MCCB로부터 연결되는 부스바의 상면에 전력케이블의 단자가 겹쳐져 체결될 시에 사용 전류의 양에 따라 굵기가 각각 다른 전력케이블을 MCCB의 최대 용량을 기준으로 하여 단자 가 접속될 수 있는 충분한 넓이를 확보함과 동시에 몸통부에 부스바용 밀착홈 및 복수개의 전력케이블용 간섭방지홈을 형성함으로써 비교적 먼 거리로 공급되는 전력케이블의 굵기에 맞는 단자를 무리 없이 단자대에 접속가능하게 한다.As described above, the terminal block having a reinforced structure according to the present invention, when the terminal of the power cable is overlapped and fastened to the upper surface of the busbar connected from the MCCB, the power cable of the MCCB is different depending on the amount of current used It secures a sufficient width to connect terminals on the basis of maximum capacity, and at the same time, it forms a close contact groove for busbars and an interference prevention groove for a plurality of power cables in the body to meet the thickness of the power cable supplied over a relatively long distance. The terminal can be connected to the terminal block without difficulty.

또한 배전반 제작 시 MCCB, 부스바 및 전력케이블을 단자대를 통해 직선 연결공법으로 접속시킬 수 있는 제작 표준화를 연출함으로써, 공정의 진행을 빠르게 할 수 있으며 도체의 절감은 물론 외관상 미려함 또한 강조할 수 있다.In addition, the production standardization that can connect the MCCB, busbar and power cable through the terminal block in a straight connection method in the production of switchboards, speed up the process and can reduce the conductors as well as the beauty of the appearance.

한편으로 절연물을 그 재질로 하는 수직부를 통해 일정간격으로 격리된 공간을 확보하고 그 수직부를 투명한 절연커버로 보호하는 절연구조를 갖도록 함으로써 도전부의 노출로 인한 인명피해의 위험을 방지할 수 있다.On the other hand, it is possible to prevent the risk of human injury due to exposure of the conductive part by securing an insulating space at a predetermined interval through the vertical part made of an insulating material and protecting the vertical part with a transparent insulating cover.
