Description

Description: TECHNICAL FIELD The present invention relates to a suspension device that is advantageous when vertically supporting a cable, and more particularly to a flat cable or the like in which a plurality of conductors are arranged and an insulating coating is applied to the conductors. The present invention relates to a cable suspension device effective for vertical support.

[Prior Art] Generally, when a cable is laid vertically, it is supported at multiple points in the middle part. However, as the size increases, the weight increases and the strength of the support points becomes a problem. The method of suspending the cable from the place is adopted. In this case, conventionally, the insulating coating of the cable 6 is stripped off and the exposed conductor end is inserted into the suspension sleeve 5 to be integrated by compression or welding, and then the insulator of the insulator 4 is used. A method of fixing to a hook 19 attached to a beam 20 of a building through a turnbuckle 3 has been adopted.

[Problems to be Solved by the Invention] However, in this case, the distance from the cable tip to the beam becomes large, and a space is required between the adjacent cables to prevent collision between the insulators and the like. Space is required, which is a problem in the case of multi-row installation.

Further, there is also a system in which the suspension sleeve 5 of the conductor gripping part is housed in a case and subjected to an insulation molding treatment, but these have a drawback that the internal insulation state cannot be confirmed and disassembly is practically difficult.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome these drawbacks of the prior art and to provide a cable suspension device that is simple, space-saving, and can be disassembled as needed, and the inside can be easily confirmed.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a metal sleeve for stripping an insulating coating from a cable end and directly compressing or welding the exposed conductor. Insulating support for suspending a metal sleeve compressed or welded to a conductor, an insulating cover for covering a metal sleeve suspended on the insulating support, and the metal surrounding the insulating cover and the insulating support. It consists of a metal case with a hole for suspension that indirectly supports the sleeve made from the side of the insulating support, and the metal case is a two-piece body for fixing the substantially U-shape on the bottom side that receives the insulating support. It is intended to provide a cable suspension device characterized by being bolted with a metal fitting interposed therebetween.

The suspension device according to the present invention can be applied to general cables, but is particularly effective for flat cables in which a plurality of conductors are arranged and a common insulating coating is applied to the conductors.

In the present invention, the insulating cover that covers the metal sleeve needs to have a material and a structure that will never cause conduction between the metal sleeve and the hanging metal case.

Further, the metal case for suspension in the present invention may be of any material and structure as long as it has a material and structure capable of supporting a heavy cable.
Further, it is preferable that the separated metal case of the cable suspension device of the present invention can be divided into two.

[Embodiment] An embodiment of the present invention will be described in detail with reference to Figs. FIG. 1 shows an embodiment in which the present invention is applied to the flat cable shown in FIG. 3 as a cross-sectional view. (A) is a front view, (b) is a side view, and (c) is a side view. FIG. After stripping off the insulator 2 which is the common coating of many conductors 1 at the tip of the cable 10 in FIG.
A metallic sleeve 11 is compressed and attached to the exposed conductor 1. A metallic sleeve 11 compressed and attached to the conductor 1 is suspended on an insulating support base 12 with a hole, which is covered with an insulating cover 13, and these are collectively halved metal case 7 for suspension. Installed in the inside, and use the bolts 8a, 8b to suspend metal case 7
Are assembled and integrated. When assembling the metal case 7 for suspension, a metal fitting 9 having a shape as shown in FIG. 1 (b) is used as a metal fitting for clamping, which is clamped on the bottom side of the metal case 7 and fastened with a bolt. The bolt fastening on the bottom side of the metal case 7 where the weight of the cable 10 is most concentrated becomes stronger, so that the cable can be reliably suspended even though the metal case 7 is divided into two parts.

When suspending the cable, the suspension hole 7s is used to suspend and support the ceiling beam through suspending metal fittings.

As shown in FIG. 2, the suspending metal fitting case 7 is provided with a case 14 having a storage space 16 on one side and a cover 15 on the other side.
It is possible to improve the work efficiency at the time of assembling by adjusting the degree.

[Operation and Effect of the Invention] According to the cable suspension device of the present invention configured as described above, the metal sleeve directly compressed or welded to the bare conductor is suspended on the insulating support and Since it is covered with an insulating cover on the insulating support, insulation measures are taken by the suspension device itself, and as a result, auxiliary members such as insulators are not required, and the space of the suspension part can be greatly reduced. Since the metal case surrounding the insulating cover is bolted in two, the inside can be easily inspected as necessary, and therefore it is simple and space-saving, and can be disassembled as necessary, The intended purpose of providing an easily identifiable cable suspension device can be fully achieved.

In addition, according to the cable suspension device of the present invention, a substantially U-shaped fixing is made on the bottom side of the two-divided metal sleeve that receives the insulating support for suspending the metal sleeve directly compressed or welded to the conductor. Since the bolts are fastened with the metal fittings sandwiched between them, the bolt fastening on the bottom side of the metal case where the weight of the cable is most concentrated becomes stronger,
Even though it is a two-part metal case, it is possible to reliably suspend the cable.
