Abstract

The invention relates to an electronic device, in particular a personal computer, having a processor which is connected on a motherboard (backplane) (1) to a system bus having address, data and control lines and to functional modules. The fact that a further daughterboard (expansion board) (2a, 2b), which is provided with a plurality of insertion locations (3), is mounted essentially parallel to the motherboard (1), the insertion locations (3) being electrically connected to the system bus, means that the number of freely available insertion locations for special user assemblies is increased and the possibility of producing a cost-effective basic device is provided. The invention is used in personal computers. <IMAGE>

Description

The invention relates to an electronic device, in particular special a personal computer, with a processor, wel on a motherboard with an address, data and control lines with system bus and with radio tion modules is connected.

One of the Siemens catalog IPC10, edition 10/92 like device in the form of a so-called industrial PC's Solving various tasks known. The industrial PC z. B. used to control actuators and driven, recording and processing of operational and Process data, visualization and archiving of operations conditions and for monitoring, controlling and regulating process variables.

The industrial PC can be used as a system unit with a so-called called motherboard be formed, which with a Processor, with function blocks and several plug spaces to accommodate expansion modules is. However, this inexpensive solution has the aftermath part that only a limited number of freely available Slots are present.

To increase the number of freely available slots, can the industrial PC as a system unit with one Slots having bus board be formed in which is the CPU module and expansion modules are pluggable. To do this, however, everyone has to operate the PC's required standard function blocks, such as Memory modules, serial or parallel interfaces and hard disk and floppy disk drive control, as a construction groups. This solution is therefore in Ver expensive right from the motherboard version.

The present invention is based on the object an electronic device of the type mentioned at the beginning create, which has a variety of slots and is inexpensive to manufacture.

This task is carried out in the characterizing part of the Claim 1 specified measures solved.

The advantages of the invention are cost inexpensive system unit in motherboard version with one system unit combined in the backplane version. No slots are required on the motherboard, which leaves more room for additional function blocks. The motherboard and essentially parallel to it expansion boards are arranged on the side walls of the electronic device mountable.

In one embodiment of the invention, the functions Modules designed as memory modules. It is too advantageous, further required for the operation of the PC standard function blocks, such as blocks for a Graphics interface, a serial or parallel cut as well as a hard disk and floppy disk drive control system, which is fixed on the motherboard are integrated, whereby the number of free ver available slots on the expansion board for special user modules increased.

In a preferred embodiment of the invention the connecting means on the motherboard in the form of a Slot formed in which the expansion board is pluggable. This makes the expansion board for service work easily from the motherboard separate.

In a further embodiment of the invention, a Adapter board provided, which is essentially right angled into the slot on the motherboard.  

The adapter board has connecting means for connecting with the expansion board. It is advantageous that thereby also function blocks on the adapter board can be integrated.

Further advantageous embodiments of the invention result itself from the further subclaims.

Based on the drawing, in which an embodiment of the Invention is illustrated, the invention as well their advantages explained in more detail.

The figure shows an arrangement for connecting two Circuit boards.

A motherboard 1 with a processor with function blocks and a system bus with address, data and control lines (not shown) is electrically connected to expansion boards 2 a, 2 b arranged essentially parallel to the motherboard 1 . The connection can e.g. B. done via a ribbon cable, which leads from a connector of the motherboard 1 to connectors of the expansion boards 2 a, 2 b. The electrical connection is used to couple the system bus and thus the processor and the functional units of the basic board 1 with slots 3 of the expansion boards 2 a, 2 b in order to exchange information between the processor, the function blocks and modules, which are in the slots 3 of the Expansion boards 2 a, 2 b are inserted. In the present example, the electrical connection is made through a slot 4 of the base board 1 . In this ver connected to the system bus slot 4 , an adapter board 5 is inserted, which is contacted by connecting means 6 with the expansion boards 2 a, 2 b. These connecting means 6 can be designed as soldered, flexible or plug-in connections. For mechanical stabilization, it is advantageous between the expansion boards 2 a, 2 b and (not Depicted) of the base board 1 insulating spacer blocks provided. So that a good cooling of the basic and expansion boards 1 , 2 a, 2 b and the modules inserted in the slots 3 is possible, the boards are provided with ventilation slots.
