상기 목적을 실현하기 위한 본 고안은 커버체에 의해 보호되는 본체(20) 상에 와셔(22)가 개재된 상태로 볼트(26)와 너트(26)가 본체(20) 상에 놓여진 가공지선(40)을 알루미늄라이너(28)를 부착한 단일구조의 누름쇠(30)로 조여주는 구성과, 상기 본체(20)는 가공지선(40)이 놓여지는 양측 모서리 부위가 여유각(θ)을 이루는 것을 특징적 구성으로 한다.The present invention for realizing the above object is a processing ground wire in which the bolt 26 and the nut 26 are placed on the main body 20 with the washer 22 interposed on the main body 20 protected by the cover body. The configuration of tightening 40 to a single structure of the pusher 30 attached to the aluminum liner 28, and the main body 20 has a clearance angle θ at both corners where the processing line 40 is placed. It is set as the characteristic structure.

상기 여유각(θ)은 본체(20) 양측 모서리가 상부로 부터 하부로 이어지는 낮은 경사면에 의해 형성된 것을 특징으로 한다.The clearance angle θ is formed by a low inclined surface from which both edges of the main body 20 extend from the top to the bottom.

상기 여유각(θ)은 본체(20) 양측 모서리가 곡률에 의해 형성된 것을 특징으로 한다.The clearance angle θ is characterized in that the edges on both sides of the main body 20 are formed by curvature.

이하, 본 고안의 일실시예를 첨부한 도면을 참조하여 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

도3과 도4는 본 고안에 의한 현수클램프의 구성을 나타낸 정면도와 평면도로서, 도면에서 부호 10은 본 고안에 의한 현수클램프 전체를 나타낸 것이다.3 and 4 are a front view and a plan view showing the configuration of the suspension clamp according to the present invention, the reference numeral 10 in the drawings shows the entire suspension clamp according to the present invention.

도면에서 현수클램프(10)는 커버체에 의해 보호되며 가공지선(40)이 놓이는 본체(20), 본체(20)에 놓여진 가공지선(40)을 누르는 알루미늄라이너(28)를 부착한 누름쇠(30), 누름쇠(30)에 누름압력을 제공하는 와셔(22)를 포함한 볼트(26)와 너트(26)의 구성을 제공한다.In the figure, the suspension clamp 10 is protected by a cover body, and the pressing body attached with the aluminum liner 28 pressing the main body 20 on which the processing line 40 is placed and the processing line 40 placed on the main body 20 ( 30) provides a configuration of the bolt 26 and the nut 26, including the washer 22 that provides the pressing pressure to the depress 30.

본체(20)는 가공지선(40)인 놓이는 길이방향의 양측 모서리가 여유각(θ)을 이루고, 이 여유각(θ)은 본체(20) 양측 모서리가 낮은 경사면을 이루는 형상으로서, 이러한 여유각(θ)은 본체(20)의 상면이 동일면적을 이루는 경우 모서리의 인접면이 평면인 경우 보다 상대적으로 가공지선(40)이 놓이는 면적이 증가한다.The main body 20 has a clearance angle θ at both edges of the longitudinal direction, which is a processing line 40, and the clearance angle θ is a shape having a low inclined surface at both edges of the main body 20. (θ) is the area where the processing ground line 40 is placed relative to the case where the upper surface of the main body 20 has the same area than the adjacent surface of the edge is a plane.

즉, 양측 모서리 부위가 여유각(θ)인 낮은 경사면을 이루는 본체(20)에는 알루미늄라이너(28)를 저면에 부착한 누름쇠(30)가 와셔(22)를 개재하여 볼트(26)와 너트(26)로 결합하는 볼팅 결합구조를 이루는 것으로서, 이러한 결합구조는 본체(20)의 상면에 다수개소에 설치된다.That is, in the main body 20 forming a low inclined surface having both corner portions having a clearance angle θ, the presser 30 having the aluminum liner 28 attached to the bottom is interposed between the bolt 26 and the nut through the washer 22. As a bolting coupling structure to couple to (26), such coupling structure is provided in a number of places on the upper surface of the main body (20).

또한 누름쇠(30)를 단일부재로 하여 너트(26)의 조임압력이 누름쇠(30)를 통해 균등하게 분산되도록 한다.In addition, the pressing member 30 as a single member so that the tightening pressure of the nut 26 is evenly distributed through the pressing member (30).

따라서 본 고안은 본체(20)의 상면에 가공지선(40)이 놓여진 상태로 볼트(26),너트(26)들에 의한 조임압력에 의해 누름쇠(30)가 가공지선(40)을 눌러 고정한 후, 현수클램프(10)에 지지된 가공송전선로의 가공지선(40) 중 전선을 지나가는 동일평면 상에서 전선 취부점을 통과하는 수평선과 전선이 이루는 각인 카테나리각(Catenary Angle)이 큰 경우에도 본체(20) 모서리와의 마찰에 의해가공지선(40)의 소선단선이 발생하지 않는다.Therefore, in the present invention, in the state in which the processing wire 40 is placed on the upper surface of the main body 20, the clamp 30 presses and fixes the processing paper wire 40 by the tightening pressure by the bolts 26 and the nuts 26. After the main body 40 of the processing line 40 of the overhead transmission line supported by the suspension clamp 10, even if the angle of the catenary angle formed by the horizontal line passing through the wire mounting point and the wire is large (20) The strand break of the processing line 40 does not occur due to friction with the edge.

일예로 카테나리각이 50도를 초과하는 경우에도 온도에 따른 이도 변화와 바람에 의한 영향 및 현수개소 양측의 불균형장력으로 가공지선(40)과 가공지선(40)용 현수클램프(10)의 본체(20) 모서리와의 마찰이 발생하여도 본체(20) 양측 모서리가 여유각(θ), 즉 낮은 경사면을 이루어 가공지선(40)과 본체(20) 모서리와의 접촉이 면접촉된 상태를 유지함으로써, 가공지선(40)이 마찰에 의한 소선단선이 방지된다.For example, even if the catenary angle exceeds 50 degrees, the main body of the suspension clamp 10 for the processing branch line 40 and the processing branch line 40 due to the change of the ear canal according to the temperature, the influence of the wind, and the unbalanced tension on both sides of the suspension site. (20) Even if friction with the edge occurs, both edges of the main body 20 form a clearance angle θ, that is, a low inclined surface, so that the contact between the processing ground line 40 and the edge of the main body 20 is in surface contact. As a result, the broken wire break due to the friction of the processing branch wire 40 is prevented.

한편, 본 고안의 가공지선(40)이 놓이는 본체(20) 상면 양측의 경사면은 대략 30 ~ 55°의 범위가 바람직하며, 경사면에 한정하지 않고 본체(20) 모서리 부위의 여유각(θ)이 곡률에 의해 형성되어도 실시가 가능하다 할 것이다.On the other hand, the inclined surfaces on both sides of the upper surface of the main body 20 on which the processing branch line 40 of the present invention is placed is preferably in the range of approximately 30 to 55 °, and the clearance angle θ of the corner portion of the main body 20 is not limited to the inclined surface. Even if formed by the curvature, it will be possible to implement.

본 고안은 가공지선과 꺽임각을 이루는 현수클램프 본체 양측의 모서리를 경사면 또는 곡률을 이루는 여유각을 두어 가공지선과의 면접촉에 의한 지지면적을 증가하는 구조로 하여 피로마찰에 의한 소선단선을 방지하여 배전선로의 유지보수에 따른 각종 부대비용이 절감과 안전성이 보장되는 효과가 있다.The present invention is designed to increase the support area due to surface contact with the processing ground line by placing the corners of both sides of the suspension clamp body forming the bending angle with the processing ground line as the inclined surface or curvature to prevent the wire breakage caused by fatigue friction. Therefore, it is effective in reducing various costs and maintaining safety of distribution line.
