BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable receiving device which is attached to a cable supporting device attached to a wall or the like and receives a cable.

[0002]

2. Description of the Related Art A cable receiver of a so-called "cable tray", which is attached to a vertical column-shaped cable support attached to a side wall surface of a tunnel or the like and supports a cable,
The semicircular curved concave surface supports the cable, but if there is a risk that the cable may fall off due to vibrations when passing through the vehicle, the cable is conventionally tied to the pan with a binding wire to prevent the cable from falling off. Was out.

[0003]

As described above, the work of binding a cable to a receiving tray with a binding wire as described above is complicated, and the work of binding a binding wire to each of a large number of receiving trays installed over a long distance in a tunnel or the like is required. Laying the cables one after another not only takes a long time, but also it is not easy to remove the binding wire and remove the cable again when removing or repairing the cable, and to promote the cable laying and maintenance work. Can not. Simply holding down the cable on the tray without such a complicated cable binding operation could cause the cable to fall out of the tray if the cable tray receives a large wind pressure when the train passes as the train speeds up. There is.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cable receiving device in which the operation of supporting a cable on a receiving tray is easy and quick, and the cable is prevented from dropping even when receiving a large wind pressure when passing through a train. Is what you do.

[0005]

In order to achieve the above object, the cable receiving device of the present invention comprises: (1) a cable support provided with a C-shaped engaging portion 5 for attaching a holding plate to a cable mounting portion 3; A cable holding plate provided with a receiving shaft portion;
The C-shaped engaging portion 5 has a C-shaped opening 6 having an opening width D, and the engaging shaft portion 15 of the cable holding plate 10 is a vertically long flat shape, and the length L of the long axis Y of the flat shape is formed. Is formed to be larger than the opening width D of the opening entrance 6a of the C-shaped opening 6 and the thickness d of the flat shape in the short axis direction is made smaller than the opening width D,
The engaging shaft 15 of the cable holding plate 10 is fitted into and engaged with the C-shaped opening 6 of the C-shaped engaging portion 5 of the cable supporting portion 1.
The cable holding plate 10 is attached to the cable support portion 1.

(2) In the cable receiver of the above (1), the locking piece 17 at the distal end of the cable holding plate 10 is locked to the distal end of the cable support portion 1.

[0007]

The cable receiver is mounted by fitting its mounting portion 2 into a fitting hole of a cable support A mounted on a side wall surface such as in a tunnel. The cable mounting portion 3 supports the cable B by placing the cable B on the cable mounting concave portion 4. The cable holding plate 10 is attached to the cable support 1 by fitting the engaging shaft portion 15 of the cable holding plate 10 into the C-shaped opening 6 of the C-shaped engaging portion 5 on the cable mounting portion 3 and hooking. The front end of the cable holding plate 10 is fixed to the cable support portion 1 and the upper surface of the cable is pressed so that the cable does not fall off.

In order to engage the engaging shaft portion 15 of the cable holding plate 10 with the C-shaped engaging portion 5, the cable holding plate 10 is set upright and the long axis Y direction of the flat portion of the engaging shaft portion 15 is set to C. Match the opening entrance 6a of the C-shaped opening 6 of the shape engaging portion 5 with the opening entrance
6a is inserted into the inner deep circular space 6b. When the cable holding plate 10 in this state is laid down sideways, the long axis Y direction of the flat portion of the engaging shaft portion 15 becomes vertical in the inner deep circular space 6b of the C-shaped opening 6, and the opening width becomes small. As a result, it becomes impossible to escape from the opening entrance 6a of D, and the engaging shaft portion 15 engages with the C-shaped engaging portion 5. The cable holding plate thus attached to the cable support 1
10 can be rotated and opened and closed with the hanging shaft portion 15 as a rotation axis, which facilitates the work of holding down the cable.

By locking the locking piece 17 at the distal end of the cable holding plate 10 to the distal end of the cable supporting portion 1, even if the cable receiving plate receives a large wind pressure when passing through a high-speed train, the cable holding plate 10 can be locked. Does not open, so that the cable does not fall out of the pan.
