Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a flat cable holder.

[Conventional technology and its problems]

In recent years, the demand for electricity in buildings, residences, factories, etc. has increased significantly as the buildings become larger and higher-rise, as well as as air-conditioning equipment increases and various office automation equipment become widespread.

However, if a round cable is used, voltage drop becomes a problem, and a large-sized cable must be used.

Therefore, flat cables with low voltage drop are increasingly used.

However, conventionally, when laying a flat cable, the ninth
As shown in the figure, attach the support fittings to the cable frame a,
A flat cable C was supported by the supporting metal fitting. That is, this support fitting includes a lower member e having a fitting groove d into which the lower end of the flat cable C fits, and an upper holding member g having a fitting hole f into which the upper end of the cable C fits. The flat cable C was held in a pinched manner by the upper and lower members g and e.

In this case, the installation method is as follows: First, attach the lower member e of the support fitting to the cable pedestal a with fixing tools such as bolts and nands, and then lift the flat cable C.
The lower end of the cable C is fitted into the fitting groove d of the lower member e, and then the upper end of the cable C is fitted into the fitting groove f of the upper member g. The flat cable was held in a pinched manner by fixing the upper and lower parts ttg and e at point k.

Therefore, in this case, it is necessary to manufacture the above-mentioned supporting metal fittings, which increases the cost.
Since the cable weight is 4 kg to 20 kg per meter, it is very troublesome to lift it by hand and drop the fitting part d of the lower member e, making the installation work inefficient. Although Fig. 9 shows the case of horizontal installation, vertical installation is also carried out by attaching the above-mentioned support fittings to the vertically installed cable frame a.
Similarly, the cost is high and the flat cable C must be refitted into the fitting grooves d and f, which is troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to solve these conventional problems and provide a flat cable holder that allows flat cables to be laid simply and quickly.

[Means for solving problems]

The flat cable holder of the present invention is a flat cable holder that holds a plurality of flat cables substantially parallel with a predetermined interval so that the long sides face each other; A generally U-shaped outer wall that surrounds one short side of the long side or the short side of the cable; and a mounting for attaching connecting members that are connected to both ends of the outer wall and connect the two ends. part: connected to the covering wall of the outer wall covering the short side part, and with the flat cable surrounded by the outer wall, the cable is interposed between the cables and the cables are spaced at predetermined intervals. An intervening protrusion for holding;

[Effect]

When configured as described above and inserting this flat cable holder into the flat cable from one short side of the cable, the intervening protrusion is inserted between the flat cables to maintain a predetermined distance between the cables. In addition, at this time, the entire flat cable is surrounded by the outer wall except for the other short side, and the outer wall can be connected with the connecting member, so that the flat cable is securely held. Retained.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the drawings showing practical examples.

FIG. 1 shows a state in which a flat cable 1 is laid using a flat cable holder 3 according to the present invention. The side portions 14 are placed on the child beams 4 of the cable rack 2, and the flat cables 1 are held at a predetermined distance from each other by the flat cable holders 3 attached to the child beams 4.

As shown in Fig. 2, the flat cable 1 consists of five conductors 5 made of highly conductive metal arranged in parallel, and a material such as cross-linked polyethylene covering the conductors 5. It is composed of an insulator 6 and a sheath 7 made of rubber, vinyl chloride, etc. that covers the insulator 6, and the entire cross section has a flat oval shape.

Therefore, this flat cable holder 3 has a substantially U-shaped outer wall 26 that surrounds the outer long side 25.25 of the flat cable 1 outside both layers to one short side 15 of the flat cable l. and a connecting member 28 (
In this case, the mounting part 9 is provided with a mounting part 9 for mounting the child beam 4), and an interposed protrusion 8 which is interposed between the cables L and holds the cables L at a predetermined interval. is fixed to the sub-girder 4 with fasteners 10.10 such as bolts and nands.

Specifically, as shown in FIG. 3, outwardly protruding flanges are connected to both ends of the outer wall 26, and the attaching portion 9 is held by the flanges.
Further, a hanging wall piece is provided hanging down from the covering wall 13 that covers the short side portion 15, and the hanging wall piece is used as the intervening projecting piece 8. Therefore, in this holder 3, a fitting groove 11 into which the flat cable 1 is fitted is formed between the side wall portion 12 of the outer wall 26 and the interposed projection piece 8. That is, the fitting grooves 11 and the intervening protrusions 8 are arranged alternately. The width dimension A of the fitting part 11 is approximately the same as the thickness dimension B (see Figure 1) of the flat cable 1, and the depth dimension C is approximately the same as the height dimension D (see Figure 1) of the flat cable 1. (see). Furthermore, the covering wall 13 side of the fitting groove 11 is arc-shaped so that the arc-shaped short side 15 of the flat cable 1 is fitted therein. Further, each of the attachment parts 9 is provided with a through hole 16 for attaching a fixing member 10 thereto.

Therefore, in order to lay a flat cable using this holder 3, first, the other short side 14 of the flat cable 1 is attached to the child girder 4 arranged at a predetermined pitch in the cable rack 2. ... and the cables 1 are arranged substantially parallel to each other. Thereafter, this holder 3 is attached to one of the cables 1 as shown by the imaginary line in FIG. It is inserted from the short side 15 side, and the holder 3 is successively fixed to the child spar 4 (connection member 28) using the fixing tool 10. In this way, the holders 3 as binding tools are inserted at predetermined notches along the length of the cable 1 and fixed to the child beams 4. Reference numeral 17 denotes a through hole that is provided through the child beam 4 in order to attach the fastener 10. At this time, when the holder 3 is fixed to the sub-spar 4, the other short side portion 14 of the cable 1 and the attachment portion 9.9 are brought into contact with the sub-spar 4.

Therefore, in this case, each cable 1 is fitted into the fitting groove 11 of the holder 3, and is securely held by the holder 3, with a predetermined interval between each cable 1.

Next, FIG. 4 shows another embodiment. In this case, the holder does not use the fixing device 10, but the connecting member 4 (the connecting member 28) ).

That is, in this case, a locking groove 19 is formed in the mounting portion 9, and the binding member 18 is wound around the locking groove 19 and the child spar 4, thereby fixing the holder 3 and the child spar 4. In addition, this intervening protrusion 8
A gap 19 is provided in the intervening protrusion 8, and the gap forming pieces 8a, 8a of the intervening protrusion 8 are elastically deformable in both directions toward and away from each other, and the intervening protrusion 8 is provided with spring properties such as a plate spring piece. to accommodate slight differences in the thickness dimension B of the flat cable 1 and to securely grip the cable 1.

Further, FIGS. 5 and 6 show still another embodiment, in which the child beam 4 is not used as the connecting member 28, but the above-mentioned binding member 1 day is used as the connecting member 28. That is, in the holder 3 in this case, as shown in FIG. 4, a locking groove 19 is formed in the mounting portion 9.9, and the locking grooves 19 and 19 are connected by a binding member 18.

Therefore, in this case, there is no need to form through holes 17 in the sub-spar 4, and there is no need to make the arrangement pitch of the holders 3 the same as the arrangement pitch of the sub-spars 4, making the installation extremely easy. .

Next, in FIG. 7, instead of using the connecting member 28 as the child beam 4, the connecting member 28 is replaced with an abutting member made of a strip plate or the like that comes into contact with the other short side 14 of the flat cable 1. Indicates when there is.

Although all of the above-described embodiments show only the case of horizontal installation, the holder 3 can of course also be used in the case of vertical installation, as shown in FIG. That is, the flat cable 1 hanging from the ceiling etc. is placed on the cable rack 2 erected from the floor etc., and the other short side 14
After arranging the cables 1 substantially parallel to each other by bringing them into contact with each other, the cable holder 3 shown in FIG. The holder 3 and the cable rack 2 are then inserted one after another at a predetermined pitch, and the holder 3 and the cable rack 2 are fixed using the fixing tool 10.

In addition, even in vertical installation, it is preferable to use the holders shown in FIGS. 4 and 5.

In this way, even in vertical installation, the cables are maintained at a predetermined distance.

It should be noted that the present invention is not limited to the illustrated embodiment, and the design may be changed without departing from the gist of the present invention. For example, the number of flat cables 1 is three in the embodiment, but it is of course possible to use a plurality of cables. For example, the number of intervening parts 8 of the holder 3 may be two, four, six, or eight, and in the case of two, the number of intervening parts 8 of the holder 3 is one, and similarly in the case of four.

In the case of three or six interposed parts 8, in the case of five or eight interposed parts 8, the number of interposed parts 8 is 711N. Furthermore, the number of conductors 5 in the flat cable 1 is of course free. The material of this holder 3 is preferably a non-magnetic material such as aluminum or plastic.

〔Effect of the invention〕

The flat cable holder of the present invention is different from conventional flat cable holders, in which the heavy cable is once lifted up and then removed from the lower part of the support fitting.
The work of falling into the fitting groove d and the work of connecting the upper and lower members g and e are eliminated, and the installation work becomes extremely simple and can be done quickly, greatly improving work efficiency. Moreover, the cable is securely held. Furthermore, the cable holder 3 has a simpler structure than conventional supporting metal fittings, and contributes to cost reduction.
