In- and/or output device for processdata.

TECHNICAL FIELD

In the invention, it is assumed that an input and / or output device according to the preamble of claim 1. Such input and / or output devices have attached to a rack and process connector and cable to a device for carrying out a process guided assemblies, which between themselves communicate via a system bus. The modules each contain at least one arranged in a housing board and accept signals from signal transmitters of process execution device, process the signals, where appropriate, of signals emitted by the other modules, and / or cause signals signal recording process execution device to. Depending on the requirement to fulfill a module input, output, input and output, and / or processing function.

STATE OF THE ART

An input and / or output device according to the preamble of claim 1 is known for example from EP-A-165,434th With this device, the process connectors are each provided with a pivot joint, which is adapted to a mechanically and electrically fixed to the printed circuit board connector. This forces are transmitted by each process connector on the power strip to the fixedly connected to the printed circuit board caused by operation, wiring and / or vibrations and acting on the front-side process connector, which in turn gives the forces on the housing to an assembly fixing rack.

SUMMARY OF THE INVENTION

The invention as defined in claim 1, solves the problem of an input and / or output device of the initially mentioned type, which is designed simple and practical, and in which the circuit board remains almost completely spared from major mechanical requirements.

The input and / or output device according to the invention is characterized in that the process initiated by the connectors in the assembly forces are transmitted almost completely mechanically modified components, such as power strip and housing, on the rack. Thus, the circuit boards are mechanically relieved and can solve tasks demanding electrical interference.

FOR CARRYING OUT THE INVENTION

The invention will now be described with reference to drawings. In the drawing:<dl id="dl0001"><dt>Fig. 1</dt><dd>a perspective view of an embodiment shown in simplified form of the input and / or output device according to the invention.</dd><dt>FIG. 2</dt><dd>a perspective view of the essential components of an assembly of input and / or output device according to Fig.1 </dd><dt>Fig. 3</dt><dd>a side view of an assembly of the input and / or output device according to Figure 1 have been removed with parts of the sub-housing, and</dd><dt>Fig.4</dt><dd>a plan view of a longitudinal section through IV-IV guided An assembly according to Fig.3.</dd></dl>

The input and / or output device illustrated in Fig.1 consists of adjacently mounted on a chassis 1, and substantially box-shaped modules 2, of which are only shown only identical from-formed for the sake of simplicity, the rack 1 with a bus holder 3 process plugs 4. the process plug 4 can be uncoupled from the module 2 and are connected to not shown signal sources and signal recording of an apparatus also not shown, for carrying out a process such as a manufacturing or a machining method in a channel 5 guided cable 6th On the back of the modules 2 are located in the upper part of each fastening claw 7 and a not apparent from Figure 1 bus connector. The fixing claw 7 engages in a attached to the rack 1 mount. 8 When installing each assembly 2 is inserted with its fastening claw 7 in the rail 8, pivoted with its back to the rack 1 and then completely fixed by a not visible screw. When swiveling the bus connector and provided on bus age 3 Buskupplung 9 form a plug connection, via which signals are in the supported by the Bush age 3 bus and thus to other modules 2 and / or from the bus 3 and can therefore be taken from other modules 2 ,

Each assembly contains according to Fig.2 from a supporting member 10 and covers 11, 12 formed housing. The supporting part 10 is formed essentially by two mutually L-shaped plates arranged, of which one as the side wall 13 and the other as back wall 14 of the housing of the assembly is used the second In the fixing claw-bearing in the upper part, but possibly containing also openings for attaching the mounting claw back wall 14 an opening 15 is provided, which is designed to implement a bus connector 16th The bus connector 16 can be mounted on the support member 10 and has not shown with conductor tracks of a printed circuit board 17 contacted and also not shown connector pins. The circuit board 17 is connected to a supportable on the supporting part 10 power strip with 18 pins, which cooperate with sockets of Prozessteckers 4, and at least one indicator diodes not shown printed circuit board carrying the 19th During assembly of the assembly 2, the plug connector 18 is fixed on the supporting part 10 and the associated printed circuit boards 17 and 19 are included in the thus formed housing by snapping the covers 11 and 12. FIG. A provided in the cover 11 opening 20 is for performing power strip 18th

the accurate formation of a module 2 can be seen from the figures 3 and 4. FIG. Thus, from Figure 3 (side view after removal of the covers 11,12) to recognize that the power strip 18 carries connector pins 21 and optionally also on the support part 10 vorsehbares bearing element 22 and a clamping screw 23, and further that a plurality of circuit boards 19 with display diodes 24 are provided. From Figure 4 (plan view along IV-IV a guided section through the assembly 2, wherein in contrast to Figure 3, the covers 11 and 12 are used and the process connector 4 is swung into the assembly 2,) it can be seen that the circuit board 17 via contact portions 25 electrically and mechanically to the circuit boards 19 that the connector strip 18 is connected by screws 26 mechanically fixed to the support member 10 of the housing of the module 2, and that the pivoted-process plug 4 is covered by a door 27, which is pivotally attached to the snapped-on the support part 10 cover 12th Further, it is apparent that the pins 21 formed curved, elastically deformable connecting parts contain 28 on which the circuit board 17 is preferably supported by means of press-fit technology.

The inventive input and / or output device operates as follows: To start up the process plug 4 after pivoting and fixing the assembly 2 by means of fastening claw 7 and clamping screw 23 on the subrack 1 first placed with a bearing element on the bearing element 22 of the plug connector 18 and through an in the plane takes place in accordance with Figure 3 rotational movement to the position shown in Figure 4. This contact is not shown and with the cables 6 are electrically conductively connected to jacks of process plug 4, the pins 21 and thus put on the interconnects and optionally provided components of the circuit board 17, an electrical operative connection between the switches and / or signal pick the device for implementing the process and the bus or other assemblies 2 ago.

As well as mechanical forces are transmitted through the cable 6, where appropriate, the swung-process plug 4 is secured for example by means of a 27 covered by the door and acting on the edge connector 18 screw against unwanted movement. The 6 induced by the cables mechanical forces are transmitted to the rack 1 on the process connector 4, the plug connector 18 and the support member 10th This is because that the Prozesstecker 4 via the through its bearing element and the bearing element 22 formed pivot joint and the screw with the connector strip 18 is positively connected, and that according to the power strip 18 rests positively by means of screws 26 on the support member 10 and this , the mounting claw 7 and the clamping screw 23 is mechanically firmly coupled to the rack. 1

The PCB 17 remains virtually free of unwanted mechanical forces. This is because that the circuit board 17 is at least maintained in the range of the terminal strip 18 only through elastically deformable pins 21st From process plug 4 in the assembly 2 guided mechanical forces, therefore, hardly affect the circuit board 17 precisely where caused would occur through the application of force, the greatest mechanical stress.

Are the bus connectors 16 corresponding to the male groin area trained and 17 fitted pins provided in the printed circuit board, which cooperate with jacks of Buskupplung 9 (Fig.1), then the printed circuit board 17 nowhere positively to the force-transmitting parts such as process plug 4, power strip 18, support member 10 and rack 1, connected and is now protected in a particularly advantageous manner to damage.
