- ESD Electrostatic discharge
- This Sensitivity increases with the degree of integration.
- For stationary and wired devices are already protective measures known that derive an applied overvoltage. A protective function can only offer these measures if a removal of the Charging to an earth line is possible. This is usually the case with stationary and wired devices. With the known However, it is not possible to take portable devices effectively protect against electrostatic discharge.
- From US-A-4 138 711 is a printed circuit board with semiconductor components known, which is connected to input contacts on the circuit board are.
- a switching device designed as a bridge switch bridges all contacts before inserting a plug. When inserting the plug, the bridge switch is in transferred to a non-bridging state before the mating connections of the connector touch the input contacts. With this However, an arrangement is made when contacting one with an overvoltage overvoltage without ESD protection transferred to the components.

It is also described by the here Features a malfunction of the device functions by ESD difficult. There is no connection to a stationary protective conductor necessary. The protection also works for any electrical device charged bodies as well as for electrically charged plug contacts, which are connected to the device.
- Switching to the essentially non-conductive state after expiration a delay time is advantageous in that the Delay time a certain period of time is made available in which equipotential bonding between the plug and the reference contact can take place. So the potential difference between the reference contact and the plug connector minimal.
- the electrically conductive connection of each connector of the electrical Component with the reference contact via a switching means has the advantage that even if several connections are exposed to ESD, there are no harmful effects Potential differences between the connections and the reference contact can build up, reducing the risk of harm to the electrical components or subcircuits connected to these connections and thus the electrical device is reduced by ESD.

- the electrically conductive connection between the input contact and the Reference contact only when approaching one equipped with a magnet Counter connection and not accidentally e.g. mechanical release through another electrically charged body.
- Another advantage is if the electrical device has a additional input contact for permanent connection with the reference contact has, since such a looping through the reference potential of the reference contact to the further electrical device having the counter connection is possible.
- FIG. 1 An electrical device 26 with a housing 1 is shown in FIG. Inside the housing 1 there is a power supply 3, to the positive pole of which a first connecting line 13 and to the negative pole of which a second connecting line 12 are connected.
- the two connecting lines 12, 13 lead to a circuit 2, likewise located in the housing 1, which comprises a plurality of electrical subcircuits n 0 , n 1 , ... n i .
- Each of these electrical subcircuits n 0 , n 1 , ... n i is connected to a third connecting line 12 ', which is connected to the second connecting line 12 at the circuit input of the circuit 2.
- On the second connecting line 12 there is a reference contact 7, to which a first connecting line 8 ′ and a second connecting line 8 are connected.
- the first connecting line 8 ′ leads to an equalizing contact 22 located on the outside of the housing 1.
- the second connecting line 8 leads via a switching means 19 to an output line 9, which leads from a circuit output of the circuit 2 to an input contact 4 located on the outside of the housing 1 leads.
- the input contact 4 is surrounded by a coupling piece 29 for receiving a plug 25.
- the plug means 25 comprises a connector housing 18, which on its Front one corresponding to the input contact 4 Has counter terminal 11. On the outside, the housing 1 also a recess 10 through which an actuation of the as Opener trained switching means 19 is possible.
- the switching means 19 has an angled probe arm 20, which in the recess 10 over the switching means 19 fits.
- the third connecting line 12 ' is preferably a line which connects all the electrical subcircuits n 0 , n 1 , ... n i to one another. Such a line is usually already present in the circuit 2, since it is common in circuit design that a circuit ground is led through the circuit.
- the compensating contact 22 is constantly connected to the reference contact 7 via the first connecting line 8 '. Charges that reach the compensation contact 22 when handling the housing 1 by touching an electrically charged body, for example a human body part, thus flow to the reference contact 7, so that this has approximately the same potential as the compensation contact 22.
- the compensation contact 22 is preferably attached at an exposed location on the outside of the surface of the housing 1 and can be of any shape (eg wire mesh, metal surface, decorative strips, etc.) and size.
- the compensation contact 22 is preferably close as the housing 1 completely enclosing metal jacket. Just like the compensating contact 22 is the input contact 4 via the switching means 19 and the second connecting line 8 is connected to the reference contact 7. Charges that reach the input contact also flow to the reference contact 7, whereby the potential difference between the Input contact 4 and the reference contact 7 is minimized. In principle becomes an electrically charged body with the reference contact 7 electrically connected.
- the connector 25 to the input contact 4 e.g. to connect the electrical Device 26 with any other electrical device, such as printers, Charger, programming device, alarm transmitter, signal transmitter, remote control device, etc.
- the counter terminal 11 first reaches an electrically conductive one Contact with the input contact 4.
- the counter terminal 11 is with resilient contact tongues equipped when hitting the input contact 4 yield elastically, while the plug 25 for a safe coupling inserted into the housing 1 deeper into the coupling piece 29 becomes. Only when the plug 25 is fully inserted into the coupling piece 29 is, the probe arm 20 causes an intervention in the recess 10 an opening of the switching means 19. By opening the switching means 19, the input contact 4 is separated from the reference contact 7, whereby the input contact 4 its actual function for the circuit 2 can exercise. However, since the input contact 4 has almost the same potential shows how the reference contact 7 is damaged in the circuit 2 due to a potential difference between input contact 4 and Reference contact 7 almost impossible.
- the counter terminal 11 and the input contact 4 should be provided when the input contact meets 4 and give counter-connection 11.
- the input contact 4 and accordingly the counter terminal 11 can have multiple contacts, i.e. be multi-pole.
- the probe arm 20 is also by the design one of the contacts as a mechanically longer pin contact replaceable in input contact 4 or mating connector 11. By the bigger one mechanical length is then ensured that this compared to the other, Shorter contacts of the input contact 4 or counter terminal 11 leads ahead and when touching the electrically conductive switching means 19 establishes an electrically conductive connection to the reference contact 7.
- a deeper insertion of the plug 25 into the housing 1 causes then preferably opening the switching means 19 before one electrically conductive connection of the other contacts of the input contact 4 with the contacts of the counter terminal 11.
- the coupling piece 29 Provided the relative Position between the input contact 4 and the counter terminal 11 to each other by other means such as the housing 1 and the connector 25 common enclosing container is secured, the coupling piece 29 also omitted.
- the plug 25 can also be connected to the device 26 be attachable accessory, on the outside of the counter connector 11 is arranged.
- a suitable reference contact is e.g. a metal layer in a multilayer circuit board.
- FIG. 2 shows a further embodiment of that shown in FIG. 1 electrical device 26 shown.
- the same numbers denote here same elements.
- the embodiment shown here differs differs from that shown in FIG. 1 by the following features:
- the second connecting line 8 does not lead via the switching means 19 to the output line 9, but directly to one on the outside of the Housing 1 attached contact element 6.
- the contact element 6 is attached to the inlet opening of a recess 27, at the The bottom of the input contact 4 is.
- the recess 27 serves instead of the coupling piece 29 from Figure 1 for receiving the plug 25.
- the top of the input contact 4 is at a depth x from the inlet opening of the recess 27.
- the plug 25 has here again a connector housing 18 on the front the counter terminal 11 is arranged with resilient contact tongues.
- the mating connector 11 has a side resilient contact tab 28 on that when inserting the plug 25 into the one in the housing 1 Indentation 27 touches the contact element 6, slides along it and when the plug 25 is fully inserted, no more contact to the contact element 6.
- the side resilient contact tab 28 slides along the contact element 6, the counter-connection arrives 11 in electrically conductive contact with the input contact 4. This electrically conductive contact is maintained when the connector 25 is fully inserted into the recess 27.
- the depth is x selected in an advantageous manner so that the lateral resilient Contact lobe 28 with plug-in means fully inserted into the recess 27 25 no longer touches the contact element 6 and discharges an electrically charged body only on the contact element 6 and can not be done on the inclusion 4.
- the interruption the electrically conductive connection between the reference contact 7 and the Counter terminal 11 also via a circuit mechanism analogous to FIG. 1 done, the choice of depth x no longer according to the above Criterion must take place.
- FIG. 3 shows an electrical device 26 to which the power supply 3, which is located in an external housing 1 ', can be connected.

- the additional switch 14 causes the line input of the first Connection line 13 on the housing 1 for connecting the power supply 3 remains connected to the reference contact 7 until the power supply 3 is connected. Charging the first connection line compared to the reference contact 7 is therefore not possible.
- the electric conductive connection of the first connecting line 13 with the reference contact 7 causes an electrically conductive connection of an electrically charged body, which extends from the housing 1 end of the first Line 13 touches, with the reference point 7. It will assumed that the electrically charged body is not that in the external Housing 1 is arranged power supply 3, but for example a inadvertently the end of the first connecting line starting from the housing 1 13 touching electrically charged body part. In this Case does not have to open the additional switch 14, in contrast to Case of connecting the power supply 3.
- Coupling the external Housing 1 'to the housing 1 causes a housing extension Open the additional switch 14 before all four coupling points in the Touch connecting lines 12, 13.
- the additional switch 14 must be on everyone Open case before connecting the power supply 3, otherwise a short circuit would result.
- the connection of the power supply 3 thus ensures that the first connecting line is touched 13 not by an electrically charged body more can be done. So here is an electrically conductive connection built between the counter terminal 11 and the input contact 4.

- the second switching means s 0 is opened by one of the extensions 33, 34, 35 before the first connecting line 13 touches the associated input d 0 , while the third and fourth switching means s 1 , s 2 only after contacting the outputs p 1 , p 2 can be opened. This means that ESD protection can also be achieved for any arrangement of contacts between the electrical device 26 and its periphery.
- FIG. 5a shows a further exemplary embodiment with a housing 1 and an associated external housing 1 'while retaining the previous numbering with the following differences: While the second connecting line 12 is connected to the reference contact 7 via the input d m on the housing surface of the housing 1 the inputs d 0 , d 1 , d 2 for connection to the first connecting line 13 or the outputs p 1 , p 2 in depressions 5 in the housing 1.
- the outputs p 1 , p 2 and the connecting lines 12, 13 have at their end pin contacts 36, 37, 38, 39 telescopically resiliently telescopically of equal length.
- the further housing 1 ′ is thus contacted first via the second connecting line 12 and only subsequently via the first connecting line 13 or the connections p 1 , p 2 .
- the spatial arrangement of the inputs d m , d 0 , d 1 , d 2 ensures that when the two housings 1, 1 'are brought together, the reference contact 7 is always used first to equalize the charge before the other contacts between the two Housing 1, 1 ', are connected.

- the coil spring 41 forms the line to the additional circuit 17.
- An indentation of pin 40 disconnects the connection that one before pressing Protection against electrostatic discharge.
- Figure 6 shows an example of a configuration with contact pins.
- the following differences exist compared to the configuration according to FIG. 4: Instead of the inputs d m , d 0 , d 1 , d 2 here contact pins k m , k 0 , k 1 , k 2 are provided which protrude from the housing 1.
- the contact pin k m is mechanically longer than the contact pins k 0 , k 1 , k 2 and accordingly protrudes further from the housing 1 than this.
