[Detailed Description of the Invention] [Summary] This invention relates to a space-saving mounting structure in a power supply distribution board for supplying power to each device of a switching system, which requires less installation space, and allows immediate detection of faulty parts in the system. , with the aim of providing a mounting structure for a power distribution panel that is easy to repair and replace, a plurality of protectors are mounted on the frame, corresponding to each of the units mounted on a plurality of frames arranged in a single row. A power supply distribution panel for the switching equipment, which is arranged in an orderly manner in the rows and configured to introduce external power to each unit through these protectors, is installed in the frame frame located at the end of the row of , installed in a narrow space extending in the depth direction perpendicular to the arrangement direction of the rows.

[Industrial application field]

The present invention relates to a power distribution board for supplying power to each device of an exchange, and more particularly to a space-saving mounting structure of the power distribution board.

[Conventional technology]

A digital switching system has many units that make up the system mounted on a standard-sized structure called a frame, and multiple frames are arranged in a row on the floor of a communication station, and the number of frames is paralleled in parallel as needed. It is configured as follows. In order to supply power to units arranged in this way, a dedicated frame for the power distribution panel is provided for each row, and this dedicated frame is large enough to handle the capacity of all the equipment in the row. A power distribution board equipped with a capacity protector is installed to introduce external power, and this is distributed to each frame, or a protector is installed at the top or bottom of each frame and the external power is introduced through this. A method is adopted in which an external power source is directly introduced into each frame and the power is distributed to the units mounted on the frame.

[Problem to be solved by the invention]

In such conventional systems, a considerable amount of space is required to install the power distribution panel, and if a failure occurs in some units of the system, a common protector (
This had the disadvantage that many other units connected to it (fuses, etc.) were also affected. Furthermore, it took time and effort to discover where in the system the failure occurred.

In view of these drawbacks of the conventional system, it is an object of the present invention to provide a mounting structure for a power distribution panel that requires less installation space, allows immediate discovery of faulty parts within the system, and is easy to repair and replace. shall be.

・[Means for solving the problem] This purpose is to orderly arrange on a frame a plurality of protectors corresponding to the units mounted on a plurality of frame frames arranged in - rows, and A power supply distribution board for the exchanger configured to introduce external power to each unit via a protector is provided on a frame arranged at the end of the row, and is perpendicular to the arrangement direction of the row. This is achieved by a mounting structure of a power supply distribution board characterized in that it is installed in a narrow space extending in the depth direction.

Hereinafter, the present invention will be explained in more detail based on preferred embodiments shown in the drawings.

〔Example〕

As shown in FIG. 1, the power distribution board IO of the present invention has the following features:
Each row of racks constituting the exchange system is installed with respect to the rack frame 1a arranged at the end thereof. This figure shows an example in which two rows of racks are arranged back to back.

The power distribution board IO is composed of a vertical flat frame 11 extending perpendicularly to the floor, and is installed in a narrow space provided at the end of the frame 1a in the extending direction They are inserted orthogonally and fixed. In the figure, the power distribution board on the near side is inserted into the frame, and the power distribution board on the other side is shown before insertion.

As shown in FIG. 2, the breakers 12 corresponding to the units mounted on the frame frames 1 constituting the row are arranged in an orderly manner on a pedestal 25 and fixed to the panel 13. A branch plate 14 is attached to the lower part of this panel 13, and a tongue piece 14a at one end thereof is connected to each breaker 12. The other end of the branch plate 14 is bent, and when the panel 13 is attached to the frame 11, a power supply pass bar 15 installed behind the frame 11 is attached.
is electrically connected and fixed.

Each breaker 12 is connected to each unit in the frame via a cable (not shown) through a terminal plate 16 provided on the top thereof.

The panels 13 configured in this manner are prepared for each frame configuring the system, and are installed on the frame 11 in an orderly arrangement in the vertical direction to form a power distribution panel as shown in FIG. do.

In the figure, reference numeral 17 indicates an alarm lamp, and 18 indicates a cable duct.

In order to install the power distribution panel IO of the present invention configured in this way in a predetermined end space, as shown in enlarged form in FIGS. 4a and 4b, the upper and lower ends of the frame 1a are Guide rails 1 are provided on both edges extending in the depth direction of the frame 1a.
Guide rails 20a and 20b correspondingly provided on frame 11 are inserted into 9a and 19b, and frame 11 is pushed into the frame 1a as it is.

As shown in FIG. 5a or 5b, a protrusion 21 protrudes from the back side of the frame 11, and this protrusion 21 engages with the seats 2, 2 provided at the back of the frame 1a, thereby changing its position. Fixed. This locking mechanism has a known structure, and detailed description thereof will be omitted.

For the power distribution board 10 inserted and fixed in this way,
The installation is completed by attaching the cover 23 from the open end of the frame 1a (see FIG. 1). This cover 23 has each panel 1
A window 23a is provided in the area corresponding to the cover 2.
The breaker can be maintained through this window without removing 3 itself.

〔Effect of the invention〕

As detailed above, according to the present invention, protectors such as breakers corresponding to the units in each frame in the system are arranged in one panel, and a plurality of panels are arranged on the frame. A power distribution panel is constructed and inserted into the frame at the end of the row in the depth direction, making it easy to understand the correspondence with each unit, and making it possible to save a lot of space when installing. Become.
