Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a distribution frame (commonly known as a main distribution frame) installed at a connection point between an external line and internal equipment in a telephone office, for example, and more particularly to a frame structure thereof.

A distribution board installed in a telephone office, etc., connects cables from external lines and cables from internal equipment to the terminals of the terminal board mounted on the distribution board in advance. The terminal board and the terminal board inside the station to which internal equipment is connected are connected by jumper wires in an arbitrary manner.

Furthermore, there are cases where the terminal board on the external line side is replaced with a test bullet.

Figure 1 is a perspective view showing a conventional example of such a distribution board.As shown in the figure, several pillars 1... are lined up in a straight line, and horizontal bars 2... It had a structure in which the vertical crosspieces 3 were installed on the opposite side, and jumper rings 4 were installed at each intersection of the horizontal crosspieces 2 and the vertical crosspieces 3.

For example, the outside terminal board 5 is mounted on the horizontal crosspiece 2, and the inside terminal board 6 is mounted on the vertical crosspiece 3, and the cable T from the external line is connected to the outside terminal board 5, and the cable from the internal equipment is connected to the outside terminal board 5. 8 to the terminal board 6 inside the station in advance, it is possible to electrically connect the cable 7 from the external line and the cable 8 from the equipment inside the station using the jumper wire 9 as desired. there were.

However, in this structure, the direction of the jumper wire 9 is changed from the horizontal direction to the vertical direction (or from the vertical direction to the horizontal direction) by one fixed point of the jumper ring 4 attached to the intersection of the horizontal side crosspiece 2 and the vertical side crosspiece 3. Because the jumper wires 9 need to be changed to Jumper wire 9 was being handed over to another worker who was pushing his arm through the mounting gap on the left and right side of wire 6.

For this reason, the jumper installation and connection work requires two workers at the same time, and the jumper wires 9.
A work space was needed to install the equipment.

In addition, since it is necessary to connect all the terminals on the outside terminal board 5 and all the terminals on the inside terminal board 6 with jumpers in any combination, the additional wiring board should be installed on the same side as the existing wiring board. The additional distribution frame had to be installed adjacent to the extension, and it was not possible to install the additional distribution frame anywhere other than on the extension of the existing distribution frame.

Furthermore, since a large number of jumper wires 9 running in the left-right direction are loaded on the horizontal crosspiece 2, the depth of the horizontal crosspiece 2 is equivalent to the space required for the horizontally laid jumper wires 9 when the maximum expansion is made. Because the depth must be prepared from the beginning,
Combined with the above-mentioned space for thrusting the arm, the disadvantage was that there were many super losses.

Furthermore, the operator who connects the jumper wire 9 to the terminal board 5 on the outside side of the station is on the front side of the terminal board 5 on the outside side of the station;
Since the worker who connects the jumper wire 9 to the terminal board works on the opposite side of the terminal board 6 inside the station, there is a work space for the worker on both sides of the wiring board where the terminal boards 5 and 6 are mounted. Therefore, the volume required for the distribution board including the work space was large, and the station building also had the disadvantage of requiring a large station building.

The present invention eliminates these conventional drawbacks, and aims to provide a distribution board with a substantially triangular prism-shaped structure for the distribution board frame, which reduces the area required for the distribution board, and which is easy to work with. That is.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a perspective view showing an embodiment of the distribution board of the present invention.

In the figure, 10 is a support (three in the figure), and 11a
11e (hereinafter collectively referred to as 11) are triangular jumper wires made of plate-like or rod-like structural members, which are fixed to the support column 10 in multiple stages to form a substantially triangular prism-shaped frame.

A continuous hole jumper ring 13a in which a plurality of holes through which the jumper wire passes are fixedly provided on the shortest side 12a of the jumper wire 11.
- 13e are attached to one side 12b of the jumper wire 11, and a cable 14 from an external line and a cable 15 from an in-office device are tied to one side 12b.

Also, on the remaining side 12c, there are terminal plates 16a to 16A on the outside side.
and terminal boards 17a to 17h are installed, and the cable 1
The end core wires 4 and 15 are connected to one fixed terminal in the terminal plates 16a to 161 and 17a to 17h, respectively.

The number and mounting positions of these terminal boards are determined depending on the number of cable cores inside the station and inside the station.

Reference numeral 18 is a communication groove for guiding jumper wires to other adjacent wiring boards, and reference numeral 19 is a communication jumper ring provided inside this communication groove 18, which has a plurality of holes through which the jumper wires pass.
A fixed number is provided.

20a is any terminal of terminal boards 16a to 161 and terminal board 1
20b is a jumper wire that connects any terminal of 7a to 17h, and 20b is a jumper wire that connects to any terminal of terminal board 16a to 161 or 17a to 17h.
This is a jumper wire that connects any terminal of the board to another adjacent distribution board.

Next, Fig. 3 shows an example in which a plurality of distribution boards according to Fig. 2 are installed side by side, and 10' in the figure is an additional support for the adjacent distribution board, and 11'a to 11'e are additional pillars. 13'a to 13'e are the same continuous hole jumper rings as above, 14' is a cable from the same external line as above, 15' is a cable from the same internal equipment as above, 16'a to 16'l are terminal plates on the outer side similar to those described above;
17'a to 17'h are terminal plates on the local side similar to those described above, and 19'
is a contact jumper ring similar to the above.

Next, in the distribution board according to the present invention, a jumper installation and connection operation for connecting a terminal to which an external line is connected and a terminal to which an in-office device is connected using jumper wires in an arbitrary manner will be described.

First, in the same distribution board, as shown in FIG. 2, when connecting, for example, a terminal on the inside terminal board 16c and a terminal on the inside terminal board 17h, the jumper wire 20a is a 21-hole jumper ring. That is, passing through the hole of the continuous hole jumper ring 13c attached to the jumper wire 11c mounted with the outer terminal plate 16c and the hole of the continuous hole jumper ring 13b attached to the jumper wire 11b mounted with the inner terminal plate 17h. becomes.

On the other hand, in the case of connection with another distribution board, for example, when connecting between the terminals of the outside terminal board 16i in the left distribution board in Fig. 3 and the terminals of the inside terminal board 11'C in the right distribution board in Figure 3. , the jumper wire 20b passes through the hole in the connecting jumper ring 13e attached to the jumper wire 11e on which the outside terminal plate 16i is mounted, is lowered straight down, passes through the hole in the connecting jumper ring 19, and enters the connecting groove 18. The jumper wire 11'a is guided along with it to the other distribution board on the right side, passes through the hole in the jumper ring 19' for connection, is raised directly above, and is mounted with the terminal board 17'c on the inside side of the right distribution panel. It passes through a hole in a continuous hole jumper ring 13'a attached to the hole.

These continuous hole jumper rings 13a to 13e, 13'a to
13'e and the connecting jumper rings 19 and 19' are fixedly provided with a plurality of holes through which the jumper wires pass, so that the direction of the many jumper wires can be changed from the horizontal direction to the vertical direction (
For example, the hole at the farthest position is used to connect to another distribution frame installed on the right side, and the hole in front of it is used to connect to another distribution frame installed on the left side. If it is determined that the connection within the same distribution board is to use holes other than those mentioned above and holes located at the same position, continuous hole jumper rings 13a to 13e, 13'a to
13'e and communication jumper rings 19 and 19' also have a line alignment function.

In addition, continuous hole jumper rings 13a to 13e, 13'a to
13'e and the connecting jumper rings 19 and 19' are shown as having holes as an example, but it goes without saying that a hole with an opening or a comb tooth shape can also have the same effect.

In the vertical portion where a large number of jumper wires gather due to this line alignment function, the jumper wires become almost parallel, and the bulge of the jumper wires is reduced compared to the case where the jumper wires intersect.

On the other hand, the jumper wires intersect in the jumper shelf part and inside the communication groove, but since the number of jumper wires in the jumper shelf part is smaller than in the vertical part of the jumper wires, the intersecting jumper wires The amount of unnecessary space created will be small.

In addition, inside the connecting groove, the gaps where the jumper wires intersect are spread out by the installation spacing of the distribution boards, so there is no need to take up much space for the connecting groove, and the unnecessary space created by the jumper wires is replaced by the jumper wires. Like the shelf part, it is small.

As described above, in the jumper installation and connection work of the distribution board according to the present invention, the jumper wire 20 can be installed by passing the jumper wire 20 through the hole of the continuous hole jumper ring 13 and the hole of the connecting jumper ring 19. Since the work can be done by only one person, and the wiring work can be done with fingertips, it is necessary to install a terminal board that allows connection work to the terminals from the front only. Since the mounting gap can be reduced, the number of jumper wires 11 at the same height can be increased, and therefore more lines can be accommodated.

In addition, although Fig. 3 shows the case where the wiring boards of the racks are installed adjacent to each other on the same floor, even if a large number of wiring boards are installed on the extension, the jumper wires between the racks are By passing all the connecting jumper rings, the wires can be passed through the connecting groove in an orderly manner, so that jumper wires between a large number of distribution boards can be laid in an orderly manner by simply extending the connecting groove 18.

Furthermore, in the wiring board of the present invention, since the operator works from the side with the terminal board when connecting jumpers, the cable 1 on the back side
Since there is no need to work from the side where 4 and 15 are located, the back side can be installed with the back close to the wall, or the backs can be installed back to back, so it can be installed on the limited floor space in the station. Multiple distribution boards can be installed.

Furthermore, even if multiple distribution frames are installed apart from each other, connecting each distribution frame through a communication groove makes it easy to connect jumper wires from the terminals of any distribution frame to the terminals of any other distribution frame. It can be done easily and orderly.

As explained in detail above, according to the present invention, it can be installed anywhere on the same floor, and it can also be installed on a wall or in close contact with each other on the back. There is no need to stick your arm inside the panel, and all you need is space to work with your fingertips, making it possible to increase the number of components mounted within the same occupied volume, resulting in extremely efficient floor space usage.

In addition, since the jumper wires are installed in a triangular shape and one side of the terminal board is set back, the space for the operator is increased, and the distance between the wiring board of the present invention and other equipment placed in front of it, or walls, pillars, etc. is reduced. can do.

On the other hand, since one person can work from one side of the distribution board, the time required for coordination such as meetings and waiting with co-workers is eliminated, allowing daily workers to work more efficiently.

In addition, the jumper wires can be arranged in an orderly manner, resulting in labor savings and other advantages.
