Description

케이블 클램핑 장치 {CABLE CLAMPING DEVICE}Cable Clamping Device {CABLE CLAMPING DEVICE}

본 발명은 케이블 및 이 외의 가늘고 긴 물체를 베이스, 예를 들면 삭도(索道;cableway)에 고정하는 장치에 관한 것이다. 특히, 본 발명은 세 개의 단심(single-core) 케이블을 고정시키는데 적합한 케이블 파스너에 관련하며, 상기 케이블은 케이블을 통해 쇼트 전류가 통과하는 동안 그리고 통과한 후에도 케이블의 기능을 유지하도록 하는 방법으로 고정되어야 한다.The present invention relates to a device for securing cables and other elongated objects to a base, for example a cableway. In particular, the present invention relates to a cable fastener suitable for securing three single-core cables, wherein the cable is fixed in such a way as to maintain the cable's function during and after the short current passes through the cable. Should be.

병렬 케이블들에 쇼트 전류가 인가되면, 쇼트시 케이블 사이에는 비교적 큰 자기력이 발생할 수 있다. 쇼트시 발생하는 자기력은 케이블들이 서로서로 상대적으로 측방으로 움직이도록 하고, 적당한 방식으로 케이블들이 지지구조에 고정되어 있지 않으면, 쇼트가 끝난 후 케이블이 더 이상 기능하기에 부적합한 정도까지 손상될 수 있다.When a short current is applied to the parallel cables, a relatively large magnetic force may be generated between the cables when shorted. The magnetic forces generated during a short allow the cables to move relatively laterally from one another, and if the cables are not secured to the support structure in a suitable manner, they may be damaged to the extent that the cables are no longer functioning after the short.

쇼트시 비교적 높은 전류가 발생할 수 있는 케이블을 배설할 때에는, 쇼트시 케이블들에 작은 변위만 일어날 수 있도록 하는 방법으로 케이블을 베이스에 연결할 필요가 있다.When laying a cable that can generate a relatively high current when shorted, it is necessary to connect the cable to the base in such a way that only a small displacement can occur in the cables when shorted.

예를 들면 병렬로 된 단심 고전압 케이블들의 클램핑에 관한 규정은 임의의 쇼트 전류 시에도 케이블 하나 하나의 무결성이 유지되어야 한다고 규정하고 있다.For example, the regulations for clamping single-core high-voltage cables in parallel stipulate that the integrity of each cable must be maintained at any short current.

문제가 되는 타입의 단심 케이블에는 전기전도성 금속 코어를 감싸는 전기절연재가 제공된다. 분명히, 통상 클램프의 형상인 고정 요소는, 쇼트시 케이블의 전기절연재에 전기절연재가 손상될 정도의 기계적인 힘이 걸리지 않도록 형성되어야 한다.Single-core cables of the type in question are provided with an electrically insulating material surrounding the electrically conductive metal core. Clearly, fastening elements, usually in the form of clamps, should be formed so that the electrical insulation of the cable is not subjected to mechanical forces such that the electrical insulation is damaged when shorted.

선행기술에 따르면, 지지구조가 금속재로 구성된 이러한 타입의 클램프에는, 바인딩 형상의 탄성재나, 클램프된 케이블과 클램프 부분을 지지하는 금속 사이에 배열되도록 된 중간층이 제공되는 것이 통상적인 실정이다. 바인딩이나 중간층은, 쇼트시 클램프와 케이블 사이에 발생한 힘이 케이블의 전기절연재를 손상시키는 것을 방지하도록 되어 있다.According to the prior art, it is usual for clamps of this type whose support structure is made of metal, to be provided with an elastic material in the form of a binding or an intermediate layer arranged to be arranged between the clamped cable and the metal supporting the clamp portion. The binding and the intermediate layer are designed to prevent the force generated between the clamp and the cable from shorting to damage the electrical insulating material of the cable.

상기한 바와 같이 각 클램프에 탄성재를 사용하는 것은 생산 단가를 증가시키고, 탄성재가 클램프에 정확히 위치되도록 하여야 하기 때문에 설치 작업을 복잡하게 한다. 또한, 작동 중 상기 탄성재가 클램프에서 움직여버려 탐탁지 않은 유지보수가 요구될 염려가 있다.As described above, the use of an elastic material for each clamp increases the production cost and complicates the installation work because the elastic material must be accurately positioned in the clamp. In addition, there is a concern that the elastic material may move in the clamp during operation, and thus, undesired maintenance may be required.

도 1은 병렬로 된 3개의 단심 케이블들이 클램프 내에 배치된 상태에서 잠금 작동 위치에 있는 케이블 클램프를 나타낸다.1 shows a cable clamp in the locked operating position with three single-core cables in parallel arranged in the clamp.

도 2는 클램프 내에 케이블들을 위치시키기에 앞서 개방 미작동 상태에 있는 케이블 클램프를 나타낸다.2 shows the cable clamp in an open non-operational state prior to placing the cables in the clamp.

도 3은 도 1의 I-I 단면을 나타낸다.3 is a cross-sectional view taken along line II of FIG. 1.

도 4는 굵은 케이블이나 케이블 다발을 고정하는데 사용된 케이블 클램프를 나타낸다.4 shows a cable clamp used to secure a thick cable or cable bundle.

본 발명의 목적은 상기 선행기술의 단점을 개선하는 것이다.It is an object of the present invention to ameliorate the disadvantages of the prior art.

상기 목적은 하기 상세한 설명과 청구항에 상술할 특징에 의한 발명에 따라 달성된다.This object is achieved in accordance with the invention by the features that are detailed in the following description and claims.

병렬 단심 케이블들의 쇼트 시험시, 적절히 디자인된 클램프는 상기 클램프가 금속판으로 이루어져 있을 지라도 탄성 바인딩을 필요로하지 않게 한다는 것이 밝혀졌다.In a short test of parallel single-core cables, it has been found that a properly designed clamp does not require elastic binding, even if the clamp is made of a metal plate.

본 발명에 따른 클램프에는, 케이블을 횡단하여 걸쳐진 측부를 따라 비교적 큰 모서리 반경부가 제공된다. 바람직한 실시예에서, 모서리 반경부는 상기 측부를 따라 금속판에 플랜지/접힘을 제공함으로써 이루어진다. 측부의 모서리 반경부는 클램프와 케이블 간의 힘의 알맞은 분배가 일어나도록 하여, 쇼트시 케이블의 전기절연재가 과부하받지 않게 한다. 따라서 케이블의 전기절연재는 본래대로 유지될 수 있고, 쇼트에 의한 고장이 고쳐진 후 정상적인 작동 전압이 인가될 수 있도록 한다.The clamp according to the invention is provided with a relatively large corner radius along the side spanned across the cable. In a preferred embodiment, the corner radius is made by providing a flange / fold on the metal plate along the side. The corner radius of the side ensures proper distribution of the force between the clamp and the cable so that the electrical insulation of the cable is not overloaded when shorted. The electrical insulation of the cable can thus be maintained intact, allowing the normal operating voltage to be applied after the short circuit fault has been corrected.

케이블의 길이방향에서 본 클램프의 개구부의 단면은 케이블들이 설치된 후 실용적인 방법으로 케이블을 지지하도록 하는 형상이다. 또한 클램프는 설치작업을 가능한한 가장 단순화하는 방법으로 형성된다.The cross section of the opening of the clamp as seen in the longitudinal direction of the cable is such that it is supported in a practical way after the cables are installed. The clamps are also formed in the simplest possible way.

이하에서는 상기 도면에 도시된, 제한 없는 바람직한 실시예를 설명한다.The following describes the preferred embodiment without limitation, shown in the drawings.

도면에서, 도면부호 1은 고정된 클램핑부(2)(이하 “보우(bow)부”이라 한다.)와, 상기 보우부(2)에 회전가능하게 연결된 힌지판(4)을 포함하는 케이블 클램프를 나타낸다.In the figure, reference numeral 1 denotes a cable clamp comprising a fixed clamping portion 2 (hereinafter referred to as a “bow portion”) and a hinge plate 4 rotatably connected to the bow portion 2. Indicates.

보우부(2)에는 삭도와 같은 형태의 베이스(미도시)에 보우부(2)를 연결하기 위해 준비된 고정 볼트(6)가 설치된다.The bow portion 2 is provided with a fixing bolt 6 prepared for connecting the bow portion 2 to a base (not shown) in the form of a ropeway.

일단에서, 상기 힌지판(4)은 보우부(2)와 힌지(8)로 연결되며, 타단에서, 상기 힌지판(4)에는 보우부(2)의 유사한 관통보어(12)와 대응하는 관통보어(10)가 제공된다. 도 1에 도시되어 있듯이, 케이블(16)들 주위로 케이블 클램프(1)가 설치되었을 때, 조여지는 보어(10, 12)에는 대응하는 수 만큼의 조임 볼트(14)가 위치한다.At one end, the hinge plate 4 is connected to the bow portion 2 and the hinge 8, and at the other end, the hinge plate 4 penetrates corresponding to a similar through bore 12 of the bow portion 2. Bore 10 is provided. As shown in FIG. 1, when the cable clamp 1 is installed around the cables 16, a corresponding number of tightening bolts 14 are located in the tightened bores 10, 12.

보우부(2)와 힌지판(4)의 단면(도 3 참조)은 단면부의 중앙부(17)가 케이블(16)에 접하여 접어진 판 구조와 같은 형상이며, 여기서 플랜지부(접힘부)(18)는 케이블 클램프(1)의 측부가 비교적 크고 볼록한 외측 반경부(20)가 되도록 형성된다.The cross section (see Fig. 3) of the bow portion 2 and the hinge plate 4 is shaped like a plate structure in which the central portion 17 of the cross section portion is folded in contact with the cable 16, where the flange portion (folding portion) 18 ) Is formed such that the side of the cable clamp 1 becomes a relatively large and convex outer radius 20.

작동 위치에서 케이블(16)의 길이방향에 대한 케이블 클램프(1)의 개구부의 단면은 모서리가 잘라진 형태의 코너를 가지는 삼각형을 형성할 것이다. 그러한 단면 형상은 적절한 직경을 가지는 3개의 케이블(16)이 유리한 방법으로 고정되도록 할 수 있거나(도 1 참조), 큰 직경을 가지는 케이블이나 케이블(22) 다발이 클램프에 고정되도록 할 수 있다(도 4 참조).The cross section of the opening of the cable clamp 1 with respect to the longitudinal direction of the cable 16 in the operating position will form a triangle with a corner in the shape of a corner. Such cross-sectional shape may allow three cables 16 with appropriate diameters to be secured in an advantageous manner (see FIG. 1), or may allow cables or bundles of cables 22 with large diameters to be clamped to the clamp (FIG. 4).

케이블(16)이 설치되기 위해서, 케이블 클램프(1)는 고정볼트(6)에 의해 베이스(미도시)에 결합된다. 그리고, 케이블(16)은 케이블 클램프(1) 내에 설치되며, 힌지판(4)은 조임 볼트(14)에 의해 잠겨진다.In order for the cable 16 to be installed, the cable clamp 1 is coupled to the base (not shown) by the fixing bolt 6. Then, the cable 16 is installed in the cable clamp 1, the hinge plate 4 is locked by the fastening bolt 14.

케이블(16)을 통해 전기 전류가 제공되는 장치(미도시)에 쇼트가 발생하면, 케이블(16)은 케이블(16)의 전기절연재의 과부하나 손상 없이도 케이블 클램프(1)에 의해 정위치에 고정된다.If a short occurs in a device (not shown) in which electrical current is provided through the cable 16, the cable 16 is held in place by the cable clamp 1 without overloading or damaging the electrical insulation of the cable 16. do.

상기한 케이블 클램프는 쇼트시에도 케이블의 전기절연재의 과부하나 손상 없이 케이블을 고정시키는 데에 이용 가능하다. 이는 적절한 직경을 가지는 3개의 케이블 또는 가늘고 긴 물체가 유리한 방법으로 고정되도록 하거나, 큰 직경을 가지는 케이블이나 케이블 다발 또는 가늘고 긴 물체가 클램프에 고정되도록 할 수 있다.The cable clamp described above can be used to fix the cable even when shorted without overloading or damaging the electrical insulation material of the cable. This may allow three cables or elongated objects of suitable diameter to be secured in an advantageous manner, or cables or cable bundles or elongate objects of large diameter to be fastened to the clamp.
