【Example】

 Embodiments will be described below with reference to the drawings. FIG. 1 is a schematic perspective view showing a first embodiment of the present invention, which is an embodiment of an apparatus in which the power is turned on only by the breaker switch. In the figure, 11 is a front switch, and the front switch 11 has a structure in which a breaker switch 13 of a power supply unit 12 is pushed by a stopper rail 14.

In the present embodiment, the stopper rail 14 engages the stopper with the engaging projection of the stopper when the breaker switch of the device is turned on, and the engaging protrusion when the breaker switch of the device is turned off. It becomes an interlocking mechanism that moves to the position where the engagement is released. Reference numeral 15 is an I / O unit assembly. The I / O unit assembly 15 connects the I / O units such as HDD and streamer and the card edge board with the flat cable and the DC supply cord as in the conventional case. The tray 16 is fixed on the upper part and an engaging hole 17 is provided at a predetermined position on the tray 16.

Reference numeral 8 denotes a card edge connector that supplies signals and power to the I / O unit of the I / O unit assembly 15. The card edge connector 8 is on a backplane board housed in a rack as in the conventional case. However, in this figure, the backplane base plate and the rack are not shown. Reference numeral 18 denotes a stopper that can move up and down freely. The stopper 18 has an engaging projection 19 that engages with the engaging hole at a regular mounting position of the I / O unit assembly 15. There are multiple corresponding to the mounting intervals.

Further, the bottom of the stopper 18 is in contact with the stopper rail 14, while the engaging protrusion 19 of the stopper rail 14 is provided on the I / O unit when the breaker switch 13 is turned on. A guide 14a for guiding the position of the bottom portion 18a of the stopper 18 is provided so as to engage with the engaging hole 17 of the assembly 15 and move to the position where the engagement is released when the assembly 15 is off.

The operation of this embodiment having the above configuration will be described below. First, when the breaker switch 13 is off, the guide portion 14a of the stopper rail 14 causes the bottom portion 18a of the stopper 18 to have a height at which the engagement protrusion 19 releases the engagement with the engagement hole 17 of the I / O unit assembly 15. It is guided so that the stopper 19 is located in the. Therefore, the I / O unit assembly 15 is free except for the connection with the card edge connector 8 of the backplane board, and can be freely inserted and removed.

On the other hand, when the front switch 11 is pushed to turn on the breaker switch 13, the stopper rail 14 slides and pushes the power switch 13 at its tip. At this time, the guide of the stopper rail 14 also moves, so that the bottom portion 18a of the stopper 18 is positioned so that the engaging protrusion 19 engages with the engaging hole 17 of the I / O unit assembly 15. Be guided. Therefore, the I / O unit assembly 15, which was free when the breaker switch 13 was turned off, is fixed by the engagement of the engagement protrusion 19.

Conversely, turning on the power means that the stopper 18 is raised and the engagement protrusion 19 is engaged with the engagement hole 17, and the I / O unit assembly 15 is fixed. That is why. At this time, if the I / O unit assembly 15 is not mounted correctly, the fixed protrusion 19 collides with the tray 16 and the stopper 18 cannot move. Therefore, even if the front switch 11 is pressed, the stopper rail 14 does not move, so that the breaker switch 13 is mechanically prevented from turning on and the power cannot be turned on.

FIG. 2 is a schematic perspective view showing a second embodiment of the present invention, which is an embodiment of a device that is turned on by a breaker switch and a control signal. The power supply of this device outputs the standby power supply (+ 5Vs) by turning on the breaker switch, and then the normal power supply (+ 5V, + 12V) is turned on by setting the power-on signal to "L" level.

In the figure, 1 is a front switch, and the front switch 20 is connected to a control circuit for a power-on signal. Reference numeral 21 denotes an electromagnet, which is energized when a breaker switch of a power supply unit (not shown) is turned on and a standby power supply is turned on. Reference numeral 15 denotes an I / O unit assembly. The I / O unit assembly 22 connects the I / O units such as HDD and streamer and the card edge board with the flat cable and the DC supply cord as in the conventional tray 16. The tray 16 is fixed on the upper part and an engaging hole 17 is provided at a predetermined position on the tray 16.

Reference numeral 8 is a card edge connector for supplying signals and power to the I / O unit of the I / O unit assembly 15. The card edge connector 8 is on a backplane board housed in a rack as in the conventional case. However, in this figure, the backplane base plate and the rack are not shown. Reference numeral 18 denotes a stopper that can move up and down freely. The stopper 18 is provided with an engagement protrusion 19 that engages with the engagement hole 17 at a regular mounting position of the I / O unit assembly 15. There are plural corresponding to the mounting intervals of.

The stopper 18 further has a bottom 18a in contact with the lever 23, and the lever 23 is attracted to the electromagnet 21 when the electromagnet 21 is energized and lifts the bottom 18a of the stopper 18 to engage the stopper 18. When the projection 19 moves to a position where it engages with the engagement hole 17 of the I / O unit assembly 15 and the electromagnet 21 is de-energized, it separates from this and the bottom 18a of the stopper 18 is lowered to engage the stopper 18. The protrusion 19 moves to the position where the engagement is released.

That is, in the present embodiment, the lever 23 and the electromagnet 21 cause the stopper 18 to engage the engaging protrusion 19 of the stopper 18 with the engaging hole 17 of the I / O unit assembly 15 when the breaker switch of the device is turned on. An interlocking mechanism that moves to the position where the engagement is released when it is turned off is configured. Reference numeral 24 is an abnormality detection switch as an abnormality detection means for detecting when the breaker switch of the device is not moved to the proper position when the breaker switch is turned on. The abnormality detection switch 24 is normally turned on and the stopper 18 is Turns off by rising.

FIG. 3 is a circuit diagram showing an example of a power-on signal control circuit of this embodiment, and FIG. 4 is an operation explanatory diagram of the same circuit. This circuit operates with a standby power supply of + 5Vs, and the power-on signal S1 becomes "L" and the power is turned on only when the abnormality detection switch 24 is off and the front switch 20 is on. Further, in this embodiment, the abnormality detection switch 24 is provided with a warning LED 25 that is turned on so that the maintenance person can be visually warned when an abnormality is detected.

The operation of the present embodiment having the above configuration will be described below. First, since the electromagnet 21 is not energized when the breaker switch is off, the lever 23 is in a state of being separated from the electromagnet 21. As a result, the bottom portion 18a of the stopper 18 has the engagement protrusion 19 and the I / O unit assembly 15 mounted thereon. The stopper 18 is guided so as to be positioned at a height at which the engagement with the engagement hole 17 is released. Therefore, the I / O unit assembly 15 is free except for the connection with the card edge connector 8 of the backplane board, and can be freely inserted and removed.

On the other hand, when the breaker switch is turned on, the electromagnet 21 is energized, so that the lever 23 is attracted to the electromagnet 21, whereby the bottom portion 18 a of the stopper 18 has the engagement projection 19 engaged with the I / O unit assembly 15. The stopper 18 is lifted so that the stopper 18 is located at a height that engages with the hole 17. Therefore, the I / O unit assembly 15, which was free when the breaker switch was turned off, is fixed by the engagement of the engagement protrusion 19.

At the same time, when the abnormality detection switch 24 is turned off and the front switch 20 is turned on, the power-on signal S1 becomes "L" level, and the normal power is turned on. Conversely, the fact that the power is turned on means that the stopper 18 is raised and the engagement protrusion 19 is engaged with the engagement hole 17, and the I / O unit assembly 15 is fixed. .

At this time, if the I / O unit assembly 15 is not mounted correctly, the fixed protrusion 19 collides with the tray 16 and the stopper cannot move. Therefore, the abnormality detection switch 24 remains on, the warning LED 25 lights up, and even if the front switch 20 is turned on, the power-on signal S1 does not go to the "L" level and the energization is controllably blocked. Is not thrown.
