Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frame structure for a portable switching device that mounts electronic units used in telephone exchanges and the like.

Conventionally, a frame structure for a switching device carried into a portable station building has been assembled using a predetermined frame.

FIG. 1 shows the rack structure of a conventional vibrating type exchanger.

In Figure 1, 1 is the wall of a portable station building, for example, the wall of a container station building, 2 is the floor of the portable station building, 3 is a cable shelf that holds cables, and 4 is a cable shelf that is fixed to the wall of the station building. Metal fittings, 5 is a frame for mounting a replacement device, 6 is a fixing metal fitting for holding the frame on a cable shelf 7 is a cable, 8 is a unit support shelf that supports a unit, 9 is a unit, 10 is a fixed interval between cable shelves It is a support rod to keep it in place.

W indicates the gap between the wall surface and the frame.

When installing the switching device and the frame shown in FIG. 2, attach the cable shelf 3 to the top of the frame on the wall 1, support the frame 5 and cable shelf 3 with fixing fittings 6, lay the cables 7 on the cable shelf 3, and install the replacement unit 9 from the cable shelf 3. The replacement device was completed by connecting cable 7, which was placed on the back of the rack carrying the unit, to the unit.

In order to install such exchange equipment, it requires a great deal of effort to bring the frame into the station building, and since the cable shelf is fixed to the top of the rack, installation of the rack and cable installation work are difficult. It was not possible to carry out the work in parallel, and the cable installation work was carried out after the installation of the racks had been completed, which took time to complete the equipment.

In addition, there must be a width between the frame and the wall indicated by W in Figure 1 that allows people to pass through for cable wiring work, maintenance, expansion, removal, etc., and this width W is required for transportable It occupied a large proportion of the narrow and limited floor space within the station building.

In order to make effective use of the floor space in the portable station building, a pond rack is also rotatably installed in front of the rack shown in Figure 1, and when necessary, it can be rotated as if opening a door to free up floor space. Although methods have been taken to deal with the issue of ensuring passage width W, the passage width W is still necessary.

SUMMARY OF THE INVENTION An object of the present invention is to provide a rack structure for a portable exchange device which has a completely new assembly structure that eliminates the above-mentioned drawbacks.

In order to achieve the above object, the present invention provides a rack structure for a switching device housed in a portable station building, including a cable shelf for holding cables fixed to the wall of the station, and a cable shelf installed close to the wall of the station. The structure consists of a plurality of pillars, each of which has been installed, and a unit support shelf that supports the units between the pillars, and cables are routed through hollow passages within the pillars to the unit support shelves on both sides of the pillars, forming a front wiring. It is characterized by eliminating the need for a gap on the back surface.

The frame structure of the present invention will be explained in more detail with reference to FIGS. 2 and 3.

FIG. 2 is a completed view of the frame structure of a portable exchange device according to an embodiment of the present invention, and FIG. 3 is an exploded view of the frame structure of FIG. 2.

The same reference numerals in FIG. 2 and FIG. 3 indicate the same thing.

In Figure 2, 1 is the wall of the portable station building, 2 is the floor, 3 is the cable shelf that holds the cable, 4 is the metal fittings that fix the cable shelf to the station wall, 7 is the cable, 18 is the unit, 11
Reference numeral 12 indicates a support column, 12 a metal fitting for connecting the cable shelf and the support column, 13 a unit support shelf with a rail for guiding the unit, and 14 a cable passage plate.

W in FIG. 2 indicates the width between the wall surface and the support.

In FIG. 3, 10 is a support rod that keeps the distance between the cable shelves 3 constant, 15 is a metal fitting that fixes the unit support shelf 13 to the support column 11, 16 is a metal fitting that holds the cable passage plate 14 on the unit support shelf 13, and 17 18 is a rail fixed to the unit support shelf, 18 is a unit, 19 is a groove that engages with the rail 17 and guides the unit when mounted on the unit support shelf, 20 is a connector part that connects the unit and a cable, 21 is a unit This groove supports the cable 7 when the cable 7 is not connected to the cable 18.

The arrow in FIG. 3 indicates the joining direction.

The cable holding groove 21 in FIG. 3 and the connector portion 20 of the unit are omitted in FIG. 2.

First, the method of assembling the frame structure of the present invention will be explained based on FIG.

Each of the parts constituting the rack shown in FIG. shelf 3
are screwed to the wall of the station building using fixing metal fittings 4, and the cable shelf 3 and the joining metal fittings 12 on the upper part of the pillars are connected with screws to create something equivalent to the left and right frame columns.

The unit support shelf 13 is fixed to the column 11 with screws using fixing metal fittings 15 with the cable passage plate 14 screwed in advance using metal fittings 16.

The whole constructed in this way forms a rack as shown in FIG.

The racking device shown in FIG. 2 has three supports 11 installed, and is composed of two racking devices, with the central support being shared by the devices on both sides.

The cables 7 on the cable shelf 3 descend down the hollow passage of the support 11 and are laid on the cable passage plate 14 to the position of the unit 18 to be connected.

When the unit 18 is not yet mounted, the connector at the end of the cable is used to hold the cable on the passage plate 14 shown in FIG. It is held by the groove 21.

After the unit 18 is mounted, the connector at the end of the cable is connected to the unit 1 as shown in the top left corner of the rack in FIG.
8 (the connector portion 20 in the unit 18 shown in FIG. 3 is omitted in FIG. 2).

)It is connected to the.

As shown in FIG. 2, in the present invention, the cables installed in the devices on both sides are grouped together at the central support 11.
It is possible to pass through the book cavity passageway, and since all cable installation is done in front of the rack, the station building wall 2 and the support 1
1 becomes almost unnecessary, and the floor space in the station building can be saved to a large extent.

Although the embodiment shown in FIG. 2 shows two racks, a plurality of racks can be sequentially assembled in the same manner.

As explained above, according to the present invention, the following effects can be obtained.

(1) Since the cable shelf, support column, and unit support shelf are each manufactured as a single unit, they can be easily transported into the station building without requiring much labor for each individual component.

(2) By simply changing the widths of the unit support shelves and the cable shelves at the top of the columns, it is possible to widen or shorten the spacing between the columns, and any unit configuration is possible.

(3) Structures such as frame columns can be carried into the station building and cable installation work can be carried out after assembly work, so there is no need to wait for the completion of the conventional frame system, and the last two small units can be placed on the unit support shelf. Because it is simply mounted on top of the machine, work efficiency is extremely high and work time is shortened.

(4) Cable installation is easy because there are cable passages in the columns and unit support shelves.

(5) The support is economical because it is used for both left and right devices.

(6) Even in the manufacturing process in the factory, the units and structures that make up the rack can be made as individual products without assembling a device that is integrated with the frame as in the past, simplifying the manufacturing process. Can be done.

(7) Furthermore, the rack device according to the present invention can be placed closely against the wall inside a portable station building, saving floor space.Furthermore, another device can be installed in front of this device by combining methods such as rotation. The saved space can be used effectively.
