본 고안은 지상 개폐기의 접속단자 구조에 관한 것으로, 특히 접속단자의 접속구멍에 접속 수나사를 나선식으로 체결하여 접속 플러그와의 연결 호환성을 개선 한 지상 개폐기의 접속단자 구조에 관한 것이다.The present invention relates to a connection terminal structure of a ground switch, and more particularly, to a connection terminal structure of a ground switch, which is connected to the connection hole of the connection terminal in a spiral manner to improve connection compatibility with the connection plug.

지상 개폐기는 대용량의 전력이 필요한 시설의 인입구에 설치되며, 화재 내지는 공사 및 여름철 과부하 등으로 일정한 구역의 전기를 잇고 끊을 때 사용되는 스위치 기기이다.Ground switchgear is installed at the entrance of a facility that requires a large amount of power, and is a switch device used to connect and disconnect electricity in a certain area due to fire, construction or summer overload.

이러한 지상 개폐기의 접속재에는 통상 도 1에 도시된 바와 같이 엘보 컨넥터(1)를 구비하며, 이 엘보 컨넥터(1)의 내부는 케이블(2)에 연결되는 아답터(3)와 이 아답터(3)에 연결되는 접속단자(5) 및, 이 접속단자(5)의 접속구멍(6)에 연결되는 접속 플러그(4), 절연캡(10) 및 개폐기 부싱(11)으로 이루어져 있다.The connection member of the ground switch is usually provided with an elbow connector 1 as shown in FIG. 1, and the inside of the elbow connector 1 is connected to the adapter 3 and the adapter 3 connected to the cable 2. It consists of a connecting terminal 5 to be connected, and a connecting plug 4 connected to the connecting hole 6 of the connecting terminal 5, an insulating cap 10, and a switch bushing 11.

여기서 종래 접속단자(5)는 도 3에 도시된 바와 같이 나선상이 형성된 접속구멍(6)을 갖는 헤드(5a)와 접속부(5b)로 이루어져 있는데, 이 접속구멍(6)에는 접속 플러그(4)의 스터드가 체결되어 사용되어 진다.Here, the conventional connecting terminal 5 is composed of a head 5a and a connecting portion 5b having a spirally connected connecting hole 6 as shown in FIG. 3, and the connecting plug 6 has a connecting plug 4. The stud of is fastened and is used.

그러나 종래 이와 같은 접속단자 구조는 모든 지상 개폐기 전체에 약 80% 정도 설치된 상태로서, 접속구멍(6)의 직경이 커서 새로 제작되는 신형 접속단자와 비교할 때 호환성이 없었다. However, such a connection terminal structure conventionally has about 80% installed in all the ground switchgear, and the diameter of the connection hole 6 is large, which is incompatible with the new connection terminal newly manufactured.

따라서 지상 개폐기를 신형으로 교체할 때 종래 접속단자를 재사용할 수가 없어서 철거하여 신형 접속단자로 교체하여야 하는데, 이때 케이블을 절단하고 새로 접속함에 따라 케이블 교체와 같은 자재와 공사비 손실이 매우 큰 단점이 있었다.Therefore, when replacing the ground switch with a new type, it is impossible to reuse the conventional connection terminal, so it must be removed and replaced with a new one. .

이에 본 고안은 상기와 같은 종래 문제점을 해결하기 위해 안출된 것으로, 접속단자의 구조를 신형 접속단자의 구조와 동일하게 변경 개량시키어 공사시 재사용이 가능하게 유지시킴에 따라 자재와 공사비 절감의 효과를 얻을 수 있는 지상 개폐기의 접속단자를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the conventional problems as described above, and the structure of the connection terminal is changed to the same as the structure of the new connection terminal, thereby maintaining the reusability during construction, thereby reducing the material and construction cost. The purpose is to provide a connection terminal of the ground switch which can be obtained.

상기와 같은 목적을 달성하기 위한 본 고안은 엘보 컨넥터 내부에 설치되어 케이블에 연결된 아답터와 접속 플러그 사이에 연결되는 지상 개폐기의 접속단자 구조에 있어서, 상기 접속단자의 헤드부에 형성된 나선상의 접속구멍에는 접속 플러그가 삽입될 수 있는 바깥둘레에 나선부를 가진 링형 수나사가 체결되되, 이 링형 수나사의 안쪽 둘레면은 밋밋한 면으로 형성되어 있다.The present invention for achieving the above object is in the connection terminal structure of the ground switch is installed inside the elbow connector and connected between the adapter and the connection plug connected to the cable, the spiral connection hole formed in the head portion of the connection terminal A ring-shaped male screw having a spiral portion is fastened to an outer circumference where the connecting plug can be inserted, and the inner circumferential surface of the ring-shaped male screw is formed into a flat surface.

이하, 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail based on the accompanying drawings.

도 1은 본 고안이 적용된 지상 개폐기의 접속재를 나타낸 부분절개 도면이고, 도 2는 본 고안의 요부인 접속단자의 분리 및 결합도이다.1 is a partial cutaway view showing a connection member of the ground switch is applied to the present invention, Figure 2 is a separation and coupling of the connection terminal which is the main part of the present invention.

그리고 본 고안은 앞서 설명한 종래 동일부분에서는 동일한 참조부호를 병기하여 설명한다.And the present invention will be described with the same reference numerals in the same conventional parts described above.

본 고안은 엘보 컨넥터(1) 내부에 설치되어 케이블(2)에 연결된 아답터(3)와 접속 플러그(4) 사이에 연결되는 지상 개폐기의 접속단자 구조에 있어서, 상기 접속단자(5)의 헤드부(5a)에 형성된 나선상의 접속구멍(6)에는 동일 재질로서 바깥 둘레에 나선부(7a)를 가진 링형 수나사(7)가 체결되되, 이 링형 수나사(7)의 안쪽 둘레면을 밋밋한 면으로 형성되어 있다.The present invention is a connection terminal structure of the ground switch, which is installed inside the elbow connector 1 and is connected between the adapter 3 connected to the cable 2 and the connection plug 4, the head of the connection terminal (5) The spiral connecting hole 6 formed in (5a) is fastened with a ring-shaped male screw (7) having a spiral portion (7a) on the outer circumference of the same material. It is.

여기서 상기 링형 수나사(7)의 내경(D)은 접속 플러그(4)의 직경보다 거의 동등하거나 약간 커서 이 접속플러그(4)의 스터드가 링형 수나사(7)의 내경(D)에 억지 끼워 맞춤식으로 삽입 결합되면 된다.Here, the inner diameter D of the ring male screw 7 is almost equal to or slightly larger than the diameter of the connecting plug 4 so that the stud of the connecting plug 4 can be forcibly fitted to the inner diameter D of the ring male screw 7. It can be inserted and combined.

그리고 상기 링형 수나사(7)의 한쪽 선단에는 체결수단을 이용할 수 있는 삽입홈(9)이 대향 형성되어 있다.And at one end of the ring-shaped male screw (7) is provided with an insertion groove (9) which can be used for fastening means.

따라서 도 2(A)에 도시된 링형 수나사(7)가 접속단자(5)의 접속구멍(6)에 체결되어진 도 2(B)와 같은 상태에서 엘보 컨넥터(1) 내부에 설치되면, 새로운 접속단자를 이용할 필요없이 호환성을 갖는 접속단자의 역할을 수행할 수 있다.Therefore, when the ring-shaped male screw 7 shown in Fig. 2A is installed inside the elbow connector 1 in the same state as Fig. 2 (B) fastened to the connecting hole 6 of the connecting terminal 5, a new connection is made. It can serve as a compatible connection terminal without the need for a terminal.

상기와 같은 본 고안에 따른 지상 개폐기의 접속단자 구조는 신형 접속단자로서 호환성을 갖는 구조를 가지기 때문에 개폐기 교체시 케이블을 포함한 각종 접속재 부품들의 재사용이 가능하여 자재 및 공사비 절감의 효과가 매우 큰 잇점을 갖는다.Since the connection terminal structure of the ground switch according to the present invention has a structure that is compatible as a new connection terminal, it is possible to reuse various connection material components including a cable when replacing the switch, thereby greatly reducing the material and construction cost.
