Description

[Detailed Description of the Invention] The present invention relates to a simple suspension clamp for covered electric wires that clamps a plurality of covered electric wires for power distribution in a bundle so as to be hooked onto the hook portion of a suitable support.

Recently, with the spread of covered electric wires for power distribution, this wire extension method has also started to be installed as a single wire body in which multiple electric wires are bundled into a twisted shape, and a simple suspension clamp is used to clamp the bundled electric wires at once. is awaited.

In view of the above circumstances, the present invention provides a suspension clamp that can be easily attached to a support and is easy to operate.

Hereinafter, the present invention will be described with reference to drawings of embodiments.

1 is a hanger part 3 with a locking hole 2 in the upper part of one end.
A U-shaped band support exhibiting a constant width, in which two split notches 4 parallel to the track direction are arranged in the curved portion 1a of the band support 1 at the top,
Rubber clamp piece 6 that can form a wire receiving groove 5 in the center
At the same time, the upper end of the clamp piece 6 is
The suspension clamp 10 is tightened with orthogonal tightening bolts 9 inserted through an insertion hole 7 and a screw hole 8 provided at the front and back of the upper part of the curved portion 1a of the band support 1. In this case, the base end of the tightening bolt 9 is the butterfly head 9a.
Since the structure allows the band support 1 to be tightened without the need for tools, and the tightening bolt 9 is of a removable type, a tip is attached to the base of the tightening bolt 9 on the side of the butterfly head 9a. is formed by attaching the connecting cable 11 locked to the band support 1 side to prevent it from detaching. 12 is a liner member installed in the wire receiving groove 5 section. Reference numeral 13 denotes a fitting step portion arranged on the outer periphery of the clamp piece 6, and the fitting step portion 13 is connected to the band support 1.
It is configured to be fitted into a fitting stepped portion 13' provided at. Reference numeral 14 denotes reinforcing ribs arranged on the side edges of the band support 1.

When using this suspension clamp 10, first pull out the tightening bolt 9 which is passed over the curved portion 1a of the U-shaped band support.

Here, the rubber clamp piece 6 is pulled up and pulled out from the open part 1b of the U-shaped band support 1, and a plurality of covered electric wires for power distribution are extended to the two split notches 4 of the clamp piece 6. 15 is made into a bundle, opened, and pushed in, and set in the lower (center) wire receiving groove 5 section. Thereafter, the clamp piece 6 is fitted back into the curved portion 1b of the band support 1. In this case, if necessary, the covered wire 15 may be directly pushed into the clamp piece 6 fitted to the band support 1 through the bifurcated notch 4 without pulling out the clamp piece 6 one by one. At this time, of course, the open portion 1b of the band support 1 is pushed and expanded to become a wide opening.

In this way, after the covered wire 15 is set on the clamp piece 6 in the band support 1, the previously removed tightening bolt 9 is inserted into the insertion hole 7 formed on the front surface of the curved portion 1a with the threaded portion 9b as the tip. By inserting the wire more tightly and screwing it into the screw hole 8 drilled on the rear surface, the open portion 1b of the band support 1 is tightened, and the clamp piece 6 located inside is tightened, so that the covered wire 15 in the wire receiving groove 5 is tightened. will be clamped. In this case, since the tightening bolt 9 passes through the guide groove 16 cut out at the upper end of the clamp piece 6, the clamp piece 6
When tightening, the two split notches 4 do not shift and open. Further, since the tightening bolt 9 has a butterfly head 9a at the base end, it can be tightened with only the fingertips without the need for any tools.

After that, if the locking hole 2 of the hanger part 3 of the band supporter 1 is hooked to a hook metal fitting 17 provided on a suitable support (not shown), the covered electric wire 15 is supported on the support side. becomes. The covered electric wire 15 at this time can be used not only in a straight line but also when stretched at a slight horizontal angle.

As mentioned above, the inventive suspension clamp for insulated wires includes a U-shaped band support, a rubber clamp piece with a wire receiving groove with two split notches that fits into the curved part, and a tightening bolt. By adopting an extremely simple configuration, a plurality of covered wires can be guided in a bundle to a rubber clamp piece, and clamped by a simple handling operation of simply tightening the curved portion with a tightening bolt. Moreover, since the tightening bolt in this case employs a thumbscrew type, it has practical effects such as being able to securely clamp the clamp by hand without the need for tools. Incidentally, this rubber clamp piece is, of course, molded from a material that can withstand long-term use, and may be made from a synthetic resin material if necessary.
