Description

[Detailed Description of the Invention] This invention relates to a suspension support device for a flat cable used, for example, as a power supply cable for an elevator.

Conventionally, this type of suspension support device is as shown in Figures 1 to 3.
As shown in the figure, a support member 6' made of a band-shaped metal plate material such as steel is formed with a series of protrusions (or grooves) 3 extending in the longitudinal direction of the support member 6' in the middle part of one side of the plate surface. , the plate on the side of the supporting member 6' having the protruding strip 3, which is horizontally suspended as a whole in a horizontal direction so that the plate surface is located in a vertical plane, and in a state substantially fixed to the ground; On the surface,
A required number of flat cables 2 extending in the vertical direction are brought into contact with one side, and the other side of the flat cable 2 is provided with the protrusions 3 in the middle of the plate surface on the opposite side. Tightening by contacting a holding member 9' made of a metal plate such as steel and forming opposing grooves (or protrusions) 4, and penetrating both the supporting member 6' and the holding member 9'. A type of cable is known in which the flat cable 2 is suspended and supported by tightening fixing members 10 such as bolts in the direction toward each other.

According to this type of suspension support device, the flat cable 2 is bent in its thickness direction by the protrusions 3 and grooves 4 within the clamping holding section formed by the support member 6' and the presser member 9'. It exerts a large deterrent force against the vertical downward sliding force due to the flat cable 2's own weight, and therefore can mechanically and firmly suspend and support the required number of flat cables 2. In the case of this suspension support device, the protrusions 3 and grooves 4 must be formed on the metal plate material itself, such as a steel band, by pressing etc. to give shape to the support member 6' and presser member 9', respectively. This model has the drawback of extremely high production costs, and although technical standards and internal wiring regulations for electrical equipment stipulate that cable anchorages must not come into direct contact with earth objects, this type of In the suspension support device, the cable jacket 11 is damaged at the suspension support part by an external force, and the cable insulator 12 is exposed from the broken part, and this comes into contact with the support member 6' and the presser member 9', which are ground objects. If this happens and further cracks occur in the insulator 12, there is a risk that electrical accidents such as ground faults and short circuits will occur immediately.

The object of this invention is to provide a suspension support device for a flat cable which advantageously solves the above-mentioned problems.

Next, this invention will be explained in detail using illustrated examples.

Figures 4 to 6 show the main parts of a flat cable suspended using a suspension support device according to an embodiment of the present invention, in which the plate surface is in a vertical plane. It is made of rubber or plastic and is made of rubber or plastic, and is formed by forming a series of convex strips 3 having a semicircular cross section in the horizontal direction on one side of a steel strip material 1 which is arranged to extend in the horizontal direction as a whole. An insulating plate 5 is fixed to form a support member 6, and a groove 4 having an arcuate cross section is formed extending horizontally on one side of a steel plate 7. The plate material 8 is fixed to constitute the presser member 9,
Further, a fixing member 10 is constituted by bolts and nuts inserted through holes 14 and 15 formed in the support member 6 and the presser member 9, and the combination of the support member 6, the presser member 9, and the fixing member 10 A type cable suspension support device 16 is constructed.

In order to suspend and support a flat cable using this suspension support device 16, first, a required number of flat cables 2, for example two flat cables 2A and 2B, are stacked on each other in the thickness direction.
One side in the thickness direction is the insulating plate material 5 in the support member 6.
comes into contact with the surface of

Next, a presser member 9 is attached to the other side of the flat cable 2 in the thickness direction.
The surface of the insulating plate material 8 is brought into contact with the supporting member 6.
and bolts across the through holes 14 and 15 of the holding member 9.
The fixing member 10 made of a nut is inserted and the pressing member 9 is tightened and fixed to the supporting member 6, thus producing the required number of flat cables 2A.

2B is held under pressure between the support member 6 and the presser member 9.

In addition, when implementing this invention, instead of doing as in the previous embodiment, the protruding strips 3 are provided protrudingly on the surface of the insulating plate material 8 on the side of the holding member 9, and the grooves 4 are provided on the surface of the insulating plate material on the side of the supporting member 6. In addition, the protrusions 3 and grooves 4 may be formed on the surfaces of the insulating plates 5 and 8 in multiple upper and lower stages, and the insulating plates 5 and 8 may be made of neoprene. Rubber or plastic materials such as , polyurethane, polypropylene, polyethylene, etc. can be used.

According to this invention, an insulating plate material 5 having a convex line (or groove) 3 and an insulating plate material 8 having a concave groove (or convex line) 4
are fixed to the surfaces of the metal plates 1 and 7, respectively, to constitute the support member 6 and the presser member 9, respectively, so that the protrusions 3 and grooves 4 are formed on each of the metal plates 1 and 7 by pressing or the like. Therefore, the supporting member 6 and the holding member 9 can be provided at low cost, and the required number of flat cables can be directly connected to the metal plate 1.
, 7, the insulating plate material 5, which has protrusions 3 and grooves 4 on each side of the flat cable 2,
Since the flat cable 2 is clamped and fixed by the support member 6 and the presser member 9 with the cables 8 in contact with each other, the external force applied to the cable jacket 11 at the support part is absorbed by the elastic buffering effect of the insulating plate 5.8. It is possible to prevent the cable jacket 11 from being damaged by mechanical external force by absorbing it, and furthermore, in the unlikely event that the cable jacket 1
1 is damaged and the insulator 12 is exposed, it will not come into contact with the metal plates 1 and 7, which are ground objects, so even if a crack or the like occurs in the insulator 12, a ground fault will occur immediately as in the conventional case. - Electrical accidents such as short circuits do not occur, and as a result, the flat cable 2 can be suspended and laid in a stable manner for a long period of time.
