본 고안은 고압차단기용 케이블 접속구구조에 관한 것으로, 특히 케이블이 차단기의 애자로 삽입되는 위치에서 연결접속한 접속구로써 케이블의 비틀림 응력에 강한 내구성을 갖게 할 목적으로 안출된 것이다.The present invention relates to a cable connection port structure for a high-voltage circuit breaker, and is particularly designed for the purpose of having a strong durability against the torsional stress of the cable as a connection port connected in the position where the cable is inserted into the breaker insulator.

일반적으로 고압차단기로의 케이블 연결접속은 야지와 연결접속되는 도체봉과 케이블 사이를 테이퍼지게 몰딩형성하여 접속하므로써 절연 및 접속 강도 보강을 했다.In general, the cable connection to the high-voltage circuit breaker is reinforced by insulating and connecting strength by tapering the connection between the conductor rod and the cable connected to the field.

이러한 종래의 고압차단기용 케이블 접속구를 살펴보면 도면 제2도에서와 같이 연격시킬 케이블(10)의 접속단을 나선부(101)로 하여 도체봉(200)의 접속공(201)에 삽입하여 외측으로부터 내측으로 압력을 가하여 협지시킨 상태에서 몰드금형에 위치시켜 케이블측으로 협소하고 차단기(애자)측으로 넓어진 테이퍼형 수지몰딩부(300)를 형성시켜서 된 것이다.Referring to the conventional cable connection port for a high voltage circuit breaker, as shown in FIG. 2, the connection end of the cable 10 to be spaced is inserted into the connection hole 201 of the conductor rod 200 from the outside by using the spiral portion 101. The tapered resin molding part 300 is formed by placing it in the mold mold in the state where it is sandwiched by applying pressure to the inside, narrowing toward the cable side and widening to the breaker (insulator) side.

이러한 조래 구조에서의 내부케이블의 도선(102)에 대한 케이블(100)의 비틀림응력을 받을때의 작용효과를 살표보면 케이블(100)의 비틀림에 따라 그 비틀림응력이 경사지게 넓어진 단면구조를 가지므로써 비틀림응력을 분산시키는 작용으로써 도선(102)의 비틀림응력에 대한 단락등을 방지하게 하였다.When the effect of the torsional stress of the cable 100 on the conductor wire 102 of the inner cable in this structure is shown, the torsional stress is inclined wider according to the torsion of the cable 100, thereby torsion. As a function of dispersing the stress, a short circuit to the torsional stress of the conductive wire 102 is prevented.

그러나 이는 전기적 특성에 의해 수지몰드물(300)의 재질이 연질의 수지물로 제조되기 때문에 실상 케이블(100)의 움직임이 클 경우에는 비틀림 응력이 도선(102)에 그대로 전달되어 단락되는 문제점이 야기되는 것으로 케이블의 비틀림응력이 보다 안전한 구조로 필요로하게 된바, 그 비틀림 응력에 대한 안전기준을 접속구의 케이블(100)단에 30kg의 중량추을 매단상태에서 접속구를 30회전 시켰을 경우에서의 상태로써 시험한 예에 의하면 상기와 같은 종래의 케이블 구조에서는 도선이 전부단락 되는 현상이 발생되었다.However, since the material of the resin molding 300 is made of a soft resin due to electrical characteristics, when the movement of the cable 100 is large, the torsional stress is transmitted to the conductor 102 as it is, causing a short circuit. As the torsional stress of the cable is required to be a safer structure, the safety standard for the torsional stress is tested as a state in which the connection port is rotated 30 times in a state in which a weight of 30 kg is attached to the cable 100 end of the connector. According to one example, in the conventional cable structure as described above, a phenomenon occurs in which the lead wires are all shorted.

이러한 현상은 도선이 서로 다른 방향으로 꼬아서 된 구조이기 때문에 중량추를 매단 케이블의 회전방향과 반대방향으로 꼬여진 도선의 풀림현상으로 연질의 수지몰드물(30)을 밀쳐내며 벌어지면서 다른 방향으로 꼬여진 도선과의 간섭등에 의해 단락이 쉽게 발생되는 것이었다.This phenomenon is because the wires are twisted in different directions, and the soft resin molded product 30 is pushed out in the other direction by the loosening of the wire twisted in the direction opposite to the rotation direction of the hanging cable. Short circuits were easily caused by interference with twisted wires.

이러한 종래의 문제점을 개선하기 위하여 도면 제3도에서와 같이 본 출원인의 선출원인 1991년 실용신안등록 출원 제8858호가 있으나, 본 고안은 상기 본 출원인의 선출원에 대한 개량고안으로 보다 낳은 비틀임응력에 대한 구조적 강성을 가지도록 할 목적으로 케이블 선단의 나선부에 근접되게 결합되는 인장코일스프링, 파이프 및 권회시킨 철편테이프와 같은 세선들뜸방지수단의 선단이 선단나선부와 물림결합접속되는 도체봉에 개재된 상태로 함께 물림결합시켜 그 구조적 강도를 보다 개선시키도록 안출된 것이다.In order to improve such a conventional problem, as shown in FIG. 3, there is a utility model registration application No. 8858 of 1991, which is the applicant's prior application, but the present invention has been developed to improve the torsional stress of the applicant's application. For the purpose of having structural rigidity, the tip of thin wire lifting means such as tension coil spring, pipe, and wound iron strip tape, which are closely coupled to the spiral part of the cable end, is interposed in the conductor bar that is bit-coupled with the tip spiral part. It is designed to improve its structural strength by biting together.

이하에서 이를 첨부도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

케이블(1)과 도체봉(2) 사이를 결합하며 상기 케이블의 내피층(13)에 근접되게 도선의 세선들뜸방지 수단으로 인장코일 스프링(4), 파이프(5)나 권회시킨 철판테이프(6)중 어느하나를 개재시킨 상태로 케이블(1)측으로부터 차단기의 애자측으로 넓어지는 테이퍼형 둘레면을 가지는 수지몰드물(3)을 형성시킨 고압차단기의 접속구에 있어서, 케이블의 선단나선부(11)가 도체봉(2)의 결합공(21)에 삽입된 상태로 선단나선부(11)와 결합공(21) 내주연사이에 세선들뜸방지수단이 물림결합된 상태에서 수지몰드물(3)로 몰딩 형성된 구조이다.A tension coil spring (4), a pipe (5) or a rolled iron sheet (6) which are coupled between the cable (1) and the conductor rod (2) and close to the inner skin layer (13) of the cable by means of the prevention of fine wire lifting of the conductor. In the connection port of the high-voltage circuit breaker in which the resin molded object 3 having a tapered peripheral surface extending from the cable 1 side to the insulator side of the circuit breaker is provided with any one of The resin molding (3) in the state in which the fine wire lifting means is bite-coupled between the tip spiral portion 11 and the inner circumference of the coupling hole 21 in a state where the rod is inserted into the coupling hole 21 of the conductor rod 2. It is a structure formed by molding.

이상과 같이 구성된 본 고안은 케이블(1)측으로 부터의 비틀림 응력을 받을 시 케이블측으로부터 넓어진 수지몰드물(3)에 의해 힘이 분산되는 작용은 물론, 내부에 몰딩설치된 세선들뜸방지수단의 반발력으로 비틀림 응력에 대항하게 되는데, 이때 이 세선들뜸방지수단의 선단이 도체봉(2)과 선단나선부(11)사이에서 물림결합되어 있기 때문에 그 구조적 강도가 배가 되는 것으로 본 출원인의 시험에 의하면 케이블(1)측에 40kg의 중량추를 매달고 접속구를 40회전 시키더라도 내부도선(12)의 단락현상이 발생되지 않았다.The present invention configured as described above has the effect of dispersing the force by the resin molding 3 widened from the cable side when subjected to the torsional stress from the cable 1 side, as well as the repulsive force of the fine wire lifting means installed therein. In this case, the structural strength is doubled because the tip of the thin wire lifting prevention means is sewed between the conductor rod 2 and the tip spiral portion 11, and according to the applicant's test, the cable ( Even if the weight of 40kg was hung on the 1) side and the connector was rotated 40 times, the short circuit of the inner conductor 12 did not occur.

이는 비틀림응력에 대한 세선들뜸방지수단의 반발저항력과 더불어 회전방향의 반대방향으로 꼬여진 도선이 부풀어 오르려는 힘이 세선들뜸방지수단의 내측면에 의해 저지되는 작용을 하는데, 이때 세선들뜸방지수단은 도체봉(2)에 물림결합되어 있으므로 그 지지기반이 보다 안정되어 있으므로 그 작용이 배가된다.In addition to the resilience resistance of the thin wire lifting means against torsional stress, the force twisted in the opposite direction of rotation direction is prevented by the inner surface of the thin wire lifting means, wherein the thin wire lifting means Since the support base is more stably coupled to the conductor rod (2), its action is doubled.

이상과 같이 구성되고 작용되는 본 고안은 케이블과 고압차단기와 연결되는 접속구의 구조에서 삽입몰딩되는 세선들뜸방지수단의 선단을 도체봉에 물림결합시켜 주므로써 보다 배가되는 비틀림응력에 대한 강성을 발하는 고품도의 접속구를 제공하는 효과가 있는 것이다.The present invention, constructed and operated as described above, exerts rigidity against torsional stress that is doubled by biting and coupling the tip of the fine wire lifting prevention means inserted and molded in the structure of the connection port connected to the cable and the high voltage breaker to the conductor rod. There is an effect of providing the connection port of FIG.
