Device for supplying power to peripheral devices of computers

The invention relates to a device for supplying power to electrical or electronic peripheral devices of computers.

Such computers have standardized slots into which plug-in cards for the computers can be inserted. Such computers are also often connected to peripheral devices that cannot be powered by the computer's power supply, but instead commercially available power supplies must be arranged to supply power to them, by means of which the mains voltage is transformed to the desired voltage values. This arrangement not only involves a lot of equipment, but also requires special supply lines to be laid, which are often disruptive.

For example, a computer has a standardized slot that has pins bl to b31. Of these pins, the bl pin is earth (GND). The b3 contact has a voltage of +5 volts, the b7 contact has a voltage of -12 volts, the b9 contact has a voltage of +12 volts and the b8 contact is a so-called NC contact (not connected).

Based on this prior art, the invention is based on the object of creating a device for supplying power of the specified type, by means of which the power supply of peripheral devices is possible in the simplest possible way and without the aid of additional power supplies.

To solve this problem, the invention proposes that the device consists of a plug-in card that can be inserted into a slot of the computer designed for a plug-in card, which has contact points with respect to the earth contact and at least one

of the contacts; + 5 volts, + 12 volts and/or - 12 volts
and NC of the computer slot in the plug-in position and that the contact points can be tapped via conductor tracks of the plug-in card in an area outside the slot.

Preferably, the contact points are part of the conductor tracks.

It is also particularly preferred that the tapping area is provided by a socket, in particular a 5-pin DIN socket,
which is arranged on an exposed edge of the insert card.

The design according to the invention makes it possible
simply by inserting the plug-in card
to provide appropriate operating voltages so that peripheral devices with the appropriate
voltage values. For example, by tapping the bl contact (grounding)
and the b3~or b9 contact it is possible to

+ 12 volts, which can be used to operate a peripheral device. It is also possible to tap a voltage of - 12 volts via the b8~ (NC) contact and the b7 contact. To make tapping easier, a DIN socket with 5 poles is preferably provided on the edge of the card, so that the power supply can be tapped using appropriate plug-in elements. Since the power consumption of the peripheral devices is essentially in the order of between 30 and 50 mA, overloading the computer can be ruled out. The invention provides an extremely simple way of supplying power to peripheral devices without the need for additional power supplies or the like.

The drawing shows a plug-in card according to the invention schematically.

The plug-in card 1 can be inserted into a corresponding slot of a computer, whereby the plug-in card

for connection to the computer's plug-in pins, it has corresponding contact points bl, b3, b7, b8 and b9, bl is an earth contact (GND), b3 has a voltage of + 5 volts, b7 has a voltage of - 12 volts, b9 has a voltage of + 12 volts and b8 is an NC contact (not connected). The contact points bl to b9 are connected to a DIN socket 7 via conductor tracks 2 to 6 of the plug-in card 1. The DIN socket has five contacts, which are shown in Figure 2. Different supply voltages can be tapped using a corresponding plug with plug-in contacts that can be inserted into the socket. For example, a supply voltage of + 12 volts can be tapped if the contact socket numbered 1 and the contact socket numbered 3 are tapped. A voltage of + 5 volts can be tapped via contacts 1 and 4, while a voltage of - 12 volts can be tapped via contacts 2 and 5.

The invention is not limited to the embodiment, but is variable in many ways within the scope of the disclosure.

All new individual and combination features disclosed in the description and/or drawing are considered essential to the invention.
