Definitions
- the present invention relates to a device enabling a master device to automatically start up at least one slave device as soon as the master device is put into service. It applies, without limitation, to the commissioning of accessory devices, such as for example a printer, a scanner, of a home computer of the PC type as soon as the latter is put into service.
- accessory devices such as for example a printer, a scanner, of a home computer of the PC type as soon as the latter is put into service.
- the solutions known up to now for automatically carrying out such a commissioning of slave devices or accessories have the drawbacks of requiring a complex electronic circuit, therefore very expensive, and of consuming a lot of electrical energy.
- the object of the present invention is to eliminate the above drawbacks of known solutions by proposing a device allowing a master device to automatically put at least one slave device into service as soon as the master device is put into service and which is characterized in that it comprises an electrolytic capacitor connected in series in the supply circuit of the master device and which can be traversed by an alternating electric current as soon as the master device is put into service to supply an AC voltage at its terminals secondary applied to a rectifier circuit supplying a rectified supply voltage of a relay whose contact is then closed to put the slave device into service.
- the capacitor is of the polarity type.
- an ohmic resistor is connected in series with the capacitor to limit the discharge current of the latter.
- the capacitor is connected in series in one of the two line and neutral supply wires from the mains of the master device and the relay contact is connected in series in one of the two neutral line supply wires from the slave appliance sector.
- the device also comprises a warning lamp, the continuous ignition of which is controlled as soon as the relay contact closes.
- the device also comprises a circuit for charging and discharging a capacitor operating as soon as the master device is put into service to control the flashing of the indicator lamp when the slave device is not connected to the mains or when the relay contact did not close after the master device was put into service.
- a means of protection against overvoltages preferably consisting of a xenon spark gap, is connected to the line and neutral supply wires.
- the device is produced on a printed circuit and integrated into a block with multiple sockets for connecting the master and slave devices to the power supply sector.
- the device of the invention will be described in the application to computer equipment comprising a home computer, of the PC type, acting as a master device and a printer, a scanner and other accessory or slave devices, but it is understood that this device can have other applications than this one.
- reference 1 schematically designates an electrical pin connector for connecting the device to the power supply, for example 220 volts.
- References 2 and 3 schematically designate sockets electrical connection to the power supply respectively of the computer and of a slave device or accessory constituted for example by a printer.
- the two sockets 2, 3 can be part of a block or multi-socket box in which the device of the invention will be integrated.
- This box may include other sockets to which other accessory devices, such as for example a scanner, may be electrically connected.
- the power supply connector 1 is connected to three terminals a, b, ç, terminal b being connected to a grounding wire of the device, while terminals a and ç can correspond respectively to the line wire and to the neutral wire for connection to the mains and between which the supply voltage of 220 volts AC appears.
- Terminal a of connector 1 is connected to a series circuit comprising a varistor 4 and a xenon spark gap 5 for earthing allowing protection of the line against overvoltages.
- the line terminals a of the two sockets 2, 3 are connected in common to the varistor 4 to protect them against overvoltages and the terminals b of these sockets are earthed.
- the terminal ç of the socket 3 is connected on the one hand to a capacitor 6 and on the other hand to another varistor 7 connected in series to the spark gap 5, as will be seen later.
- a protective fuse 8 is arranged in the connection wire to the terminal ç of the connector 1.
- the terminals ç of the connector 1 and of the connection socket 2 to the computer are connected via 'an electrolytic capacitor 9 and a resistor 10 connected in series with the capacitor 9.
- the latter is of the polarity type.
- the two terminals of the capacitor 9 are connected to the input terminals of a rectifier circuit 10 constituted by a diode bridge ⁇ 11, known per se, whose output terminals are connected at the terminals of an electrolytic capacitor with polarities 12 to which a diode 14 is mounted in parallel.
- the two terminals of the diode 14 are connected to the solenoid coil of a relay 15 whose contact 16 makes it possible to connect the terminal ç of the socket 3 at the terminal a of the connector 1 through the varistors 4, 7.
- the relay contact 16 also makes it possible to connect the terminal c of the socket 3 to the anode of a diode 17 whose cathode is connected to the anode of a diode 18 by means of a resistor 19.
- the cathode of the diode 18 is connected to the capacitor 6 and to a control lamp 20, such as for example a neon lamp, which is also connected to a capacitor 21 and at terminals a of connector 1 and sockets 2, 3.
- the terminal of capacitor 21 opposite to that connected to terminals a of connector 1 and sockets 2, 3 is connected to the anode of diode 18.
- the diodes 17 and 18 and the resistor 19 constitute a circuit for charging and discharging the capacitor 21 so as to make the lamp 20 flash when the computer has been put into service and the flashing of this lamp continues if the accessory device ( printer) is not connected to socket 3 or that the relay contact 16 has not closed.
- the resistor 10 is intended to protect the capacitor 9 by limiting the discharge current thereof and in the event of micro-cuts in the mains current lasting approximately 1 ms, the capacitor 9 will again provide a signal over two periods alternative so that micro-cuts will not be perceptible by the computer.
- the master device connected to socket 2 could also automatically put into service, by closing the relay contact 16, a secondary device connected to socket 3 having a standby circuit which would be ordered as soon as contact 16 is closed to put the slave device into service.
- the capacitor 9 can have a capacity of 100 microfarads and provides an AC voltage of 5 volts at its terminals.
- the various electronic components of the device of the invention can be installed on a printed circuit integrated into the multiple socket box with the lamp 20 occupying the place of that which is used in traditional boxes to indicate the connection of the box to the mains.
- the device of the invention allows energy savings of about 60% compared to previous situations where users often forget to turn off secondary or slave devices, such as the printer or the scanner in the context of a IT equipment, after switching off the master device (in this case the computer). This then results in an increase in the life of the devices connected by the device of the invention. Combined with spark gap 5, the device provides complete protection against overloads on the mains network.
