Description

[Detailed explanation of the idea] The present invention relates to a power supply structure for electronic devices.

An electronic device, for example, an electronic exchange, is configured to include a plurality of rack devices with various functions, and a monochrome device usually has a rack frame with multiple shelves and a plurality of electronic circuit units consisting of electronic circuit packages. , the electronic circuit unit is mounted in each column of the frame.

The present invention is particularly directed to electronic devices such as this rack device.

Incidentally, in this type of electronic device, as electronic circuits have become denser and faster due to recent advances in element technology, it has become increasingly necessary to supply low voltage and large current direct current.

In addition, electronic circuit packages are also becoming more dense due to higher density and higher integration of elements, and electronic circuit units that are made up of multiple electronic circuit packages are becoming smaller due to higher density. It is now possible to mount multiple electronic circuit units in each column of the frame.

Usually, for electronic equipment, multiple types of power supply units are centrally mounted at the bottom of the frame, and the power supply units transform the external power supply into the various power supplies required by the winter type sub-circuit units, and these power supplies are connected to the well-known vertical power supply bus. It has a structure in which power is supplied through the

In addition, this power supply was such that electronic circuit units mounted in each column of the frame that required the same power supply were commonly supplied with power to the vertical power supply bus.

For this reason, in conventional power supply structures, when the current consumption of the power supply that commonly supplies power to electronic circuit units is large, the vertical power supply bus has to be This has disadvantages, such as increasing the number of vertical power buses, increasing the mounting area for vertical power buses, and increasing installation and wiring work.

Furthermore, if one power supply unit fails, the electronic circuit unit that is commonly supplied with power to each phase will stop, and the device will no longer function.

Furthermore, in the past, when an electronic circuit unit is expected to be added, it is necessary to extend the vertical power supply bus to the corresponding digit position and prepare a power supply path in advance, which occupies a large amount of one mounting area, which is uneconomical.

The present invention is intended to solve the above-mentioned conventional drawbacks, and includes a frame with multiple shelves and a plurality of electronic circuit units such as electronic circuit packages. This can be achieved by installing a plurality of power supply units in each column in addition to the electronic devices mounted on each phase, and configuring the electronic circuit units of each phase to be independently supplied with power by the power supply units. .

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

1.2.3 are views showing the electronic device according to the present invention. FIG. 1 is a schematic perspective view showing the central part of the rack, FIG. 2 is a schematic perspective view showing an enlarged shelf part, and FIG. The figure is a schematic plan view showing the lower part of the rack.

In the figure, 1 is a frame, 2 is a shelf, 3 is an electronic circuit unit, 4 is a power supply unit, 5 is a horizontal power bus, 6.6' is a power supply connector, and I is a power distribution board.

In the storage space of the frame 1, a plurality of shelves 2 are attached, and a power distribution panel I is provided at the bottom of the shelf 2.

Further, a plurality of electronic circuit units 3 and power supply units 4 are mounted on the shelf 2, and a horizontal power supply bus 5 is attached corresponding to each phase 2.

The external power source is introduced into the power distribution board 1, and then distributed to the power supply units 4 of each phase 2 via cables 8.

The power supply unit 4 transforms the external power supply voltage into various power supplies required by the group of electronic circuit units 3 mounted on the shelf 2.

The various transformed power supplies are transferred from the power supply unit 4 to the horizontal power supply bus 5.
A power supply connector 6 and a horizontal power supply bus 5 leading to the power supply connector 6 and a power supply connector 6 leading to the electronic circuit unit 3 from the horizontal power supply bus 5 to the electronic circuit unit 3.
Power is supplied to the electronic circuit unit 3 via '.

The horizontal power supply bus 5 is, for example, a long printed board, and is provided with a receiving connector connected to the printed conductor of the board and into which a power supply connector 6, 6' is inserted.

As shown in a perspective view in FIG. 4, the electronic circuit unit 3 has a back wiring board 10 fixed to the rear inside a housing 9, and an electronic circuit consisting of a printed board on which electronic components are mounted on a connector 11 on the board 10. The package 12 is configured to be inserted and removed.

Furthermore, some of the plurality of electronic circuit packages 12 are equipped with a receiving connector 13 into which a power supply connector 6' is inserted. Ru.

As shown in a perspective view in FIG. 5, the power supply unit 4 has circuit components for power transformation, such as transistors and power transistors, housed in a housing, and a connector 14 for receiving external power and supplying transformed power to the housing. A connector 15 is provided.

The above-mentioned rack device according to the present invention is configured such that the electronic circuit unit group in the shelf 2 is supplied with power by the power supply unit 4 provided in each phase 2 of the rack frame 1, independently of other electronic circuit unit groups. ing.

Therefore, since the rack system of the present invention has a structure in which power is supplied to each column, it is possible to supply sufficient power compared to conventional systems, and there is no risk that the entire system will stop functioning even if one power supply unit fails. There is little sex.

Moreover, since the power supply unit corresponds to the electronic circuit unit group, the number of power supply units can be changed according to the increase or decrease in the number of electronic circuit unit groups, so that the power supply device can be used economically and efficiently.
