FIG. 6 is a view showing an erroneous insertion prevention mechanism. FIG. 7 is a diagram showing a first modification of the erroneous insertion prevention mechanism. FIG. 8 is a diagram showing a second modification of the erroneous insertion prevention mechanism.

The computer shown in FIG. 1 (a) has a power supply system of 100 V installed in, for example, an office,
The computer 1 has a frame 2 in which a relay plate 3 is mounted, and the relay plate 3 is abutted against the frame 2. In this embodiment, a total of four input unit units 4 are connected via connectors. To be implemented. Each input unit 4 has a plug 5.

FIG. 2 shows the connector connection state of FIG. 1 (a). The input unit 4 has two unit-side connectors 10, one for load and one for signal. A device-side receiving connector 9 is arranged at a position facing the unit-side connector 10 as a connector to be fitted with the unit-side connector 10. By connecting these connectors to each other, 100V power is supplied to the computer.

In addition to the device side receiving connector 9, another device side receiving connector 9'is provided on the device side. Then, the device side receiving connector 9'is connected to the adjacent device side receiving connector 9'on the device side, or in the case of 100V system, that part becomes an empty connector.

The input unit 4 has the circuit configuration shown in FIG. 4, and is connected to the low-pass filter 40 via the plug 5 having an allowable current of 15 A or less and to each line when the load system is two lines. The fuses 41, 41 and the ACSs 42, 42 opened and closed by a control signal for controlling the line validity of the load system. It should be noted that, from the input condition of the AC power cord (AC code), 1
The plug is limited to 15A because it needs to be 5A or less.

The computer 1 shown in FIG. 1 (b) has, for example, a power supply system of 200 V installed in a dedicated computer room, and the computer 1 has a frame 2 and a relay plate 3 inside thereof. Is mounted, and a plurality of input unit units 6 and 7 are mounted via a connector so as to abut the relay plate 3. Although the input unit 6 has the plug 8, the input unit 7 does not have it. Since the 200V power supply has a current capacity of about 1/2 that of the 100V power supply, the number of power supply cords can also be reduced to 1/2, so that one input unit 7 has no plug. Then, the input unit 6 and the input unit 7 are combined to form a unit corresponding to the input unit 4 in FIG.

FIG. 3 shows the connector connection state of FIG. 1 (b). Input section units 6 and 7 are each unit side connector 1
There are two 0s, one for load and one for signal. A device-side receiving connector 9 is arranged at a position facing the unit-side connector 10 as a connector to be fitted with the unit-side connector 10. Then, the device side receiving connector 9'which was an empty connector in the 100V system and the unit side connector 10 'of the input unit 6, 7 are connector-fitted in the 200V system. Although it has been described above that the power supply cord is halved in the case of 200 V, this line serves as a communication passage for supplying the power from the input unit 6 to the input unit 7.

By connecting these connectors to each other, 200V power is supplied to the computer. The input section units 6 and 7 have the circuit configuration shown in FIG. 5, and the low-pass filter 50 is provided through the plug 8 having an allowable current of 15 A or less.
When the load system is two lines, the fuses 60, 60 connected to the respective lines, and the ACS 6 which is opened / closed by a control signal for controlling the line validity of the load system
1, 61. Since the input condition of the AC power cord (AC code) requires 15 A or less for each input, the plug with a limit of 15 A is used.

In the 200 V system, since the input unit 6 and the input unit 7 form one unit, the line from the low-pass filter 50 is further branched and the fuse 70,
The fuses 70, 70 are connected to the ACSs 71, 71, respectively.

By doing so, different power supply systems are subdivided into a plurality of input section units, and even if the power supply systems are different, there is structural compatibility with the connector.
It is possible to easily realize power supply in units of units.

Next, erroneous insertion will be described. Since different power systems have compatibility at the unit level, it is necessary to take measures against incorrect insertion. That is, it is necessary to prevent the mixed mounting of the 100V system unit and the 200V system unit.

FIG. 6 is a diagram showing this erroneous insertion prevention mechanism. A mechanism 1 for providing guide pieces 101 and 102 on the apparatus side and for fastening and fixing the guide pieces 101 and 102 to the relay plate 100 provided with the apparatus side receiving connector 9.
03, for example, a screw stop is formed.

As shown in FIG. 6A, in the case of the input unit 4 which is a 100V power source, the relay plate 100 is fixed to the guide piece 101. The position of the device side receiving connector 9 is determined by fixing, and the unit side connector 1 which projects in advance corresponding to the position of this connector 1
By forming 0 in the input unit 4, only the input unit 4 can be fitted with the connector.

As shown in FIG. 6B, in the case of the input section units 6 and 7 which are 200 V power sources, the relay plate 1 is used.
00 is fixed to the guide piece 102. By doing so, the position of the device-side receiving connector 9 in the case of the input unit 4 is different. Further, since the unit side connector 10 of the input unit 6, 6 is formed at the position corresponding to the formation position of the connector 9, only the input unit 6, 7 can be fitted with the connector.

The relay board 100 is not divided into input unit units, but can be fitted to a plurality of input unit units. Therefore, if you fix it for one of the input unit even at one place, the relay board 1
The positions of all the 00 connectors are such that only the input unit can be fitted.

FIG. 6 (c) shows a case in which the input unit 4 is inserted into the relay plate 100 having the connector arrangement for the input units 6 and 7, and the connector cannot be fitted to the mounting plate. Input unit 4 from 104
FIG. 7 is a view showing a state in which the power supply system is protruded, so that the wrong insertion preventing mechanism of FIG.

FIG. 7 shows a first modification of the erroneous insertion prevention mechanism. In the mechanism of FIG. 6, the arrangement of the connectors is determined by fixing the relay plate 100 to the guide piece, but in this example, the relay plate 106 is slidable, and the connector projection surface of the relay plate 106 is A positioning member 107 having a triangular cross section is formed in advance.

The position of the device side receiving connector 9 formed on the relay plate 106 is initially set so as to correspond to the position of the unit side connector 10 of the input section unit 4 of the 100V system. The connector fitting of the input unit 4 can be realized as shown in FIG. Similar to the relay plate 100 in FIG. 6, if this relay plate 106 is fixed at one place for either input unit, all the connectors of the relay plate 106 can be fitted only to that input unit. It will be arranged.

As shown in FIG. 7B, a positioning member 109 having a triangular cross section is projected in advance from the input section units 6 and 7 of the 200V system.
It corresponds to the positioning member 107 formed on No. 06. When the connector is fitted to the relay plate 106, the positioning members 109 of the units 6 and 7 and the positioning member 107 of the relay plate 106 slide on their surfaces to allow the relay plate 106 to slide, and the relay The position of the device-side receiving connector 9 of the relay plate 106 moves as the plate 106 slides. On the other hand, the unit side connector 10 of the input section units 6 and 7 is the unit side connector 10 of the input section unit 4.
Since the formation positions of both are displaced, the connector 9 and the input unit units 6 and 7 moved by the sliding of the relay plate 106.
Only the connector 10 of 1 is fitted.

FIG. 8 is a diagram showing a second modification of the erroneous insertion prevention mechanism. In both the examples of FIGS. 6 and 7, the connector arrangement is changed and the relay plate is moved in parallel to the mounting surface to realize the erroneous insertion. However, in this example, the input unit units 4 and 6, The size in the depth direction is made different among the seven, and the relay plate 111 is moved in the depth direction.

That is, the input unit 4 having a size larger than that of the input units 6 and 7 is provided, and the relay plate 111 is supported by the spring 113 with respect to the guide piece 112 to move in the depth direction (double-headed arrow direction). It is like this. When the input unit 4 is fitted to the relay plate 111 by the connector, the input unit 4 pushes the relay plate 111 in the depth direction so that the input units 6 and 7 smaller than the input unit 4 can be fitted with the connector. Disappear. If the input unit 4 is attempted to be fitted with the connector while the input units 6 and 7 are fitted to the connector, the tip of the unit may be projected onto the mounting surface 104 to notify the erroneous insertion.

By doing so, it is possible to prevent mixed mounting by the input unit of different power supply systems. In addition, erroneous insertion prevention can be realized by combining the configuration of FIG. 6 or 7 with the configuration of FIG.

[0038]

As described above, according to the present invention, since no transformer device or the like is required, it is possible to reduce the customer's power supply equipment investment and the installation space. In addition, arrangement and maintenance management can be simplified.
