In addition, the semicircular groove 31 may be formed in the form of a screw. That is, it is sufficient if the electric wire can be wound or unwound in the semicircular groove by the rotation of the third insulator body 30.

제1,2,3애자본체(10,20,30)는 절연성이 높은 사기, 유리, 합성수지등의 소재로 형성되는 것이 바람직하다.The first, second and third insulators 10, 20 and 30 are preferably formed of a material having high insulation, such as porcelain, glass and synthetic resin.

전선보호 플레이트(40)는 제1애자본체(10)의 상면 중심으로부터 상호 직교되는 4방향으로 제1애자본체(10)의 반경보다 길게 수평연장되는 제1 내지 제4수평판(41a,41b,41c,41d)과, 제1 내지 제4수평판의 각 종단으로부터 수직하방으로 제2애자본체(20)의 확장부분(22) 위치까지 연장되는 제1내지 제4수직판(42a,42b,42c,42d)으로 이루어져 있다.The wire protection plate 40 includes first to fourth horizontal plates 41a and 41b horizontally extended longer than a radius of the first insulator body 10 in four directions orthogonal to each other from the center of the upper surface of the first insulator body 10. 41c and 41d and the first to fourth vertical plates 42a, 42b and 42c extending vertically from each end of the first to fourth horizontal plates to the position of the extended portion 22 of the second insulator body 20. , 42d).

이하에서는, 이와 같이 구성된 본 실시 예의 작용 및 효과에 대해 설명한다.Hereinafter, the operation and effects of the present embodiment configured as described above will be described.

제1 또는 제2애자본체(10,20)를 철탑등의 고정대상체에 나사결합체를 이용하여 고정한다. 그리고, 전선이 제3애자본체(30)의 반원형 요홈(31)에 권취되어 지지되도록 한다.The first or second insulator body (10, 20) is fixed to the object to be fixed, such as a steel tower using a screw coupling body. Then, the electric wire is wound around and supported by the semicircular groove 31 of the third insulator body 30.

반원형 요홈(31)의 개구부측 전방에 전선보호 플레이트(40)의 제1 내지 제4수직판이 위치되어 있어, 반원형 요홈(31)에 권취된 전선은 반원형 요홈(31)에 인입된 상태에서 제1 내지 제4수직판에 의해 가압밀착되므로 이탈이 방지된다.The first to fourth vertical plates of the wire protection plate 40 are positioned in front of the opening side of the semicircular groove 31, so that the electric wire wound in the semicircular groove 31 is drawn in the semicircular groove 31 in the first state. Since it is press-contacted by the fourth vertical plate, the separation is prevented.

또한, 제3애자본체(30)의 반원형 요홈(31)에 권취되어 제3애자본체(30)의 양측으로 연장된 전선에 외력(풍력, 조류의 앉음)으로 장력이 발생될 수 있다. 이때, 제3애자본체(30)가 회전되어 장력이 더 크게 발생되는 방향으로 전선을 풀어 장력을 완화시킬 수가 있다. In addition, a tension may be generated by an external force (wind power, tidal current) on the wire wound around the semicircular groove 31 of the third insulator body 30 and extending to both sides of the third insulator body 30. At this time, the third insulator body 30 is rotated to loosen the wire in a direction in which the tension is greater, thereby reducing the tension.

즉, 제3애자본체(30)의 반원형 요홈(31)에 권취되어 제3애자본체(30)의 좌/우측으로 이어지는 전선에 발생된 장력에 따라, 제3애자본체(30)가 회전되어 지지된 전선이 좌/우측으로 이동됨으로써, 장력을 완화시킬 수 있게 된다.That is, the third insulator body 30 is rotated and supported in accordance with the tension generated in the semicircular groove 31 of the third insulator body 30 and directed to the left / right side of the third insulator body 30. The tensioned wires can be relaxed by moving the left and right wires.

이와 같이, 제3애자본체(30)의 반원형 요홈(31)에 권취된 전선이 반원형 요홈(31)으로부터의 이탈되는 것이 방지되고, 전선에 발생된 장력에 따라 전선이 자유로이 이동됨으로써 장력을 완화시킬 수가 있다.In this way, the electric wire wound in the semi-circular groove 31 of the third insulator body 30 is prevented from being separated from the semi-circular groove 31, and the wire is freely moved in accordance with the tension generated in the wire to relax the tension. There is a number.
