Generally, when powering a large computer, it is common to use a power supply unit arranged in parallel with a logic unit in a control housing.

However, as semiconductor elements have become highly integrated and mounted at high density, the current consumption inevitably becomes large, and the parallel power supply units alone cannot handle the operating current for the logic units. It's gone.

Therefore, in the above publication, as a means for supplying a large current to the logic unit, there is disclosed a technique in which the power supply module rack is formed vertically long and rotatable in the same housing.

[Problems to be solved by the invention]

However, in the above technology, since the logical unit and the power supply module rack are provided in the same housing, the arrangement of each unit and module in the housing becomes complicated,
There was also a limit to the number of internal power supply modules (power supply capacity). Moreover, as shown in FIG. 5 of JP-A-62-92707, most of the power supply module rack was rotated out of the housing and pulled out during maintenance of the power supply module. Due to the structure, the housing was unstable and it was easy to fall.

The present invention has been made focusing on the above problems,
It is an object of the present invention to provide a power supply technology capable of supplying a large amount of power, easy to maintain, and capable of stable installation.

The above and other objects and novel features of the present invention will be apparent from the description of the present specification and the accompanying drawings.

[Means for solving problems]

The outline of a typical invention among the inventions disclosed in the present application will be briefly described as follows.

That is, the power supply to the control housing is performed from a separate power supply housing, the output bar from the power supply module rack rotatably mounted inside the external power supply housing, and the relay bar on the control housing side. Is connected by a flexible flexible bar.

[Action]

According to the above means, since the power supply housing is separate from the control housing, it is possible to cope with an increase in the number of power supply modules, and the power supply module rack has a structure that is rotatable inside the power supply housing. The installation stability of the body can be maintained high.

Inside the control housing 1, a power supply unit 5 is arranged in parallel at a position facing the logic rack 3, and a part of power supply to the logic unit 4 is provided in the power supply unit 5 arranged in parallel. Has been done from. However, in this embodiment,
Since the power supply capacity of the logic unit 4 mounted on the logic rack 3 is as large as several thousand amperes, for example, the power supply unit 5 arranged in parallel cannot supply the required current, and the power supply from the power supply housing 2 described below is required. Also needs.

A power supply module rack 6 which is rotatable about a fulcrum is mounted inside the power supply chassis 2 adjacent to the control chassis 1, and a plurality of power supply modules 7 are mounted on the power supply module rack 6. ing. As described above, in the present embodiment, the power supply module 7 is mounted in the power supply housing 2 which is separate from the control housing 1. Therefore, the capacity of the power supply can be easily increased by changing the power supply module rack 6 or the like. I can deal with it.

The power supply structure from the power supply module 7 to the logic unit 4 will be described in more detail with reference to FIG.

In FIG. 2, a vertically long power supply module rack 6 is provided.
In this structure, a total of 6 power supply modules 7 are arranged in two rows in the horizontal direction and three rows in the vertical direction. The power supply module 7 is attached to the power supply module rack 6 by fixing means such as bolts 8 and its output is an output horizontally extending laterally from the rear side of the power supply module rack 6 in FIG. It has a structure that is performed through the bar 10. In addition, the power supply module rack 6 has a side surface of the power supply module rack 6 which is centered around the fulcrum portion 12 of the rotation assisting member 11 mounted near the upper end and the lower end of the power supply module rack 6 in the power supply housing 2.
It is possible to rotate about 90 degrees.

The output bar 10 is formed of a conductive metal such as copper (Cu), and a flexible bar 13 as shown in FIG. 3 is connected to the tip of the output bar 10. For example, the flexible bar 13 has a structure in which plate electrodes 14 are formed at both ends and an intermediate portion thereof is a band body 15 in which a large number of conductive wires are braided, and the surface thereof is covered with a flexible insulating tube 16 made of resin or the like. There is. One end of the plate electrode 14 is connected to the tip of the output bar 10 by a fixing means such as a bolt 8.
The other end of is connected to a relay bar 17 fixed to the control housing 1 side at the boundary between the control housing 1 and the power supply housing 2.

Inside the control housing 1, each power feeding system divided by the relay bar 17 for each channel is supplied to the logic unit 4 via an L-shaped bar 18. On the other hand, for the 0V system that electrically serves as a return circuit, the relay bar
Power is supplied to the logic unit 4 from the frame 20 via the 0V bar 21 from the 17. According to this structure, since the power supply module rack 6 is arranged in the power supply housing 2 at a position close to the logic unit 4 on the control housing 1 side, the power supply housing 2 is connected to the control housing 1. Even when it is provided separately, it is possible to prevent voltage drop during power feeding without lengthening the power feeding path, and to maintain stable operation of the device.
