Abstract

The present invention relates to a plug connector (6), in particular to a SUB-D plug connector (6). According to the invention, the plug connector (6) has an electrically conducting earthed discharge protection element (13, 16) on its front face (8), this element being, for example, a metal strip (13) which runs between the two rows of contacts (10,11) of the plug connector (6). By virtue of this discharge protection element (13,16), the plug connector (6) can be used as an interface to the programming device in a safety-oriented stored-program control which is to satisfy IEC standard 801-2/3. <IMAGE>

Description

Die vorliegende Erfindung betrifft einen Steckverbinder, insbesondere einen SUB-D-Steckverbinder, z. B. für eine speicherprogrammierbare Steuerung,

  • mit einer Anzahl von Kontaktelementen, z. B. Kontaktbuchsen, deren Kontaktenden gegen einen mit dem Steckverbinder korrespondierenden Gegensteckverbinder mit mit den Kontaktelementen korrespondierenden Gegenkontaktelementen, z. B. Kontaktsteckern, gerichtet sind,
  • mit einem elektrisch isolierenden Grundkörper, in dem die Kontaktelemente gehalten sind.
The present invention relates to a connector, in particular a SUB-D connector, for. B. for a programmable logic controller,
  • with a number of contact elements, e.g. B. sockets, the contact ends against a corresponding with the connector mating connector with the contact elements corresponding counter-contact elements, for. B. contact plugs are directed
  • with an electrically insulating base body in which the contact elements are held.

Derartige Steckverbinder sind weit verbreitet. Sie werden unter anderem bei speicherprogrammierbaren Steuerungen als Schnittstelle zum Anschließen eines Programmiergeräts verwendet. Zumindest bei dieser Verwendung als Programmiergerätschnittstelle ist der Steckverbinder frei zugänglich. Wenn nun z. B. eine Bedienungsperson den als Schnittstelle zum Programmiergerät dienenden Steckverbinder versehentlich oder absichtlich berührt, kann es, falls diese Person statisch aufgeladen ist, zu einem Funkenüberschlag, also einer elektrostatischen Entladung, kommen. Dabei kann es geschehen, daß der Funke nicht auf eine den Steckverbinder seitlich umgebende Abschirmung überspringt, sondern auf eines der Kontaktelemente des Steckverbinders. Bei einem Überspringen des Funken auf eines der Kontaktelemente kann die speicherprogrammierbare Steuerung in ihrem Programmablauf gestört werden. Insbesondere bei sicherheitsgerichteten speicherprogrammierbaren Steuerung ist jedoch auch bei elektrostatischer Entladung eine einwandfreie Funktion der speicherprogrammierbaren Steuerung zwingend erforderlich und auch vorgeschrieben.Such connectors are widely used. Among other things, they are used in programmable logic controllers as an interface for connecting a programming device. At least when used as a programming device interface, the connector is freely accessible. If z. B. an operator accidentally or deliberately touches the connector serving as the interface to the programming device, if this person is statically charged, a sparkover, that is, an electrostatic discharge, may occur. It can happen that the spark does not jump to a shield surrounding the connector on the side, but to one of the contact elements of the connector. If the spark jumps onto one of the contact elements, the programmable controller can be disturbed in its program sequence. In particular in the case of safety-related programmable logic controllers, proper functioning of the programmable logic controller is absolutely necessary and also prescribed in the case of electrostatic discharge.

Im Stand der Technik wurde bisher entweder der Steckverbinder abgedeckt oder die Kontaktelemente mit Schutzschaltungen versehen.In the prior art, either the connector was previously covered or the contact elements were provided with protective circuits.

Die Abdeckung des Steckverbinders ist jedoch unzureichend, weil in bestimmten Situationen, nämlich insbesondere zum Anschließen des Programmiergeräts, die Abdeckung zwangsweise entfernt werden muß und dadurch der Steckverbinder wieder ungeschützt ist, d. h. wiederum die Gefahr einer elektrostatischen Entladung auf eines der Kontaktelemente gegeben ist.However, the cover of the connector is insufficient because in certain situations, namely in particular for connecting the programming device, the cover must be removed and the connector is again unprotected, i. H. again there is a risk of electrostatic discharge on one of the contact elements.

Durch eine Schutzschaltung sind die Kontaktelemente zwar gegen statische Entladung geschützt, die Schutzschaltung ist jedoch sehr aufwendig, weil jeder einzelne Kontakt separat gegen statische Entladungen abgesichert werden muß. Außerdem benötigen Schutzschaltungen zusätzlichen Platz auf der speicherprogrammierbaren Steuerung.The contact elements are protected against static discharge by a protective circuit, but the protective circuit is very complex because each individual contact must be separately protected against static discharges. In addition, protective circuits require additional space on the programmable logic controller.

Der Erfindung liegt folglich die Aufgabe zugrunde, mit einfachen, kostengünstigen und platzsparenden Mitteln eine elektrostatische Entladung auf eines der Kontaktelemente mit Sicherheit zu verhindern.The invention is therefore based on the object to prevent electrostatic discharge to one of the contact elements with certainty using simple, inexpensive and space-saving means.

Die Aufgabe wird dadurch gelöst, daß mindestens ein elektrisch leitendes, mit einem Schutzpotential, z. B. dem Massepotential, verbundenes Entladungsschutzelement in Richtung des Gegensteckverbinders vor den Kontaktenden angeordnet ist.The object is achieved in that at least one electrically conductive, with a protective potential, for. B. the ground potential, connected discharge protection element is arranged in the direction of the mating connector in front of the contact ends.

Bei herkömmlichen SUB-D-Steckverbindern sind die Kontaktelemente in zwei Kontaktreihen angeordnet. Bei Anordnung der Kontaktelemente in Zwei Kontaktreihen kann das Entladungsschutzelement beispielsweise als zwischen den zwei Kontaktreihen verlaufender Metallstreifen ausgebildet sein. Wenn der Metallstreifen darüber hinaus in den Grundkörper eingebettet ist, sind an dem mit dem Steckverbinder korrespondierenden Gegensteckverbinder keine konstruktiven Maßnahmen nötig. Es kann also der Gegensteckverbinder in unveränderter Form weiter benutzt werden. Insbesondere kann bei speicherprogrammierbaren Steuerungen das zur Programmierung verwendete Programmiergerät bzw. das verwendete Verbindungskabel weiter verwendet werden.In conventional SUB-D connectors, the contact elements are arranged in two rows of contacts. When the contact elements are arranged in two contact rows, the discharge protection element can, for example, be between the two Contact rows of metal strips extending. If the metal strip is also embedded in the base body, no structural measures are necessary on the mating connector corresponding to the connector. The mating connector can therefore continue to be used in unchanged form. In particular, in the case of programmable logic controllers, the programming device or the connecting cable used for programming can continue to be used.

Alternativ ist es auch möglich, das Entladungsschutzelement als auf die Frontfläche aufgebrachte metallische Beschichtung auszubilden. Auch in diesem Fall ist der bisher verwendete Gegensteckverbinder weiterhin benutzbar.Alternatively, it is also possible to design the discharge protection element as a metallic coating applied to the front surface. In this case, too, the mating connector previously used can still be used.

Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels, anhand der Zeichnungen und in Verbindung mit den weiteren Ansprüchen. Dabei zeigen:

FIG 3

FIG 4
einen weiteren Steckverbinder.
Further advantages and details emerge from the following description of an exemplary embodiment, using the drawings and in conjunction with the further claims. Show:
FIG. 1
the central unit of a programmable logic controller;
FIG 2
a connector;
FIG 3
a section through the connector of Figure 2 and
FIG 4
another connector.

Gemäß FIG 1 besteht die Zentraleinheit einer modular aufgebauten speicherprogrammierbaren Steuerung im wesentlichen aus folgenden Elementen:

  • Einer nicht dargestellten, im Inneren des Gehäuses 1 angeordneten elektronischen Schaltung;
  • einer im Gehäuse 1 angeordneten Pufferbatterie 2;
  • Stromversorgungsanschlüssen 3;
  • einem steckbaren Speichermodul 4;
  • einem RUN/STOP-Schalter 5 nebst Zustandsanzeige sowie
  • einem Steckverbinder 6, der mit der im Gehäuse 1 angeordneten Schaltung verbunden ist und als Schnittstelle zum Anschließen eines Programmiergeräts dient.
According to FIG. 1, the central unit of a modular programmable controller essentially consists of the following elements:
  • An electronic circuit, not shown, arranged inside the housing 1;
  • a buffer battery 2 arranged in the housing 1;
  • Power supply connections 3;
  • a plug-in memory module 4;
  • a RUN / STOP switch 5 with status display and
  • a connector 6, which is connected to the circuit arranged in the housing 1 and serves as an interface for connecting a programming device.

Gemäß FIG 2 und 3 ist der Steckverbinder 6 als 15poliger SUB-D-Steckverbinderbuchse nach DIN 41652 ausgebildet. Er weist, wie allgemein üblich, eine seitliche Abschirmung 7 auf, die mit dem Massepotential verbunden ist. Die Frontfläche 8 des elektrisch isolierenden Grundkörpers 9 weist eine zwischen den Kontaktreihen 10, 11 verlaufende Längsnut 12 auf, in die als Entladungsschutzelement ein Metallstreifen 13 eingebettet ist. Der Metallstreifen 13 ist unlösbar mit der Abschirmung 7 verbunden. Der Metallstreifen 13 kann beispielsweise mit der Abschirmung 7 verlötet oder einstückig verbunden sein.According to FIG 2 and 3, the connector 6 is designed as a 15-pin SUB-D connector socket according to DIN 41652. As is generally customary, it has a lateral shield 7, which is connected to the ground potential. The front surface 8 of the electrically insulating base body 9 has a longitudinal groove 12 running between the contact rows 10, 11, in which a metal strip 13 is embedded as a discharge protection element. The metal strip 13 is permanently connected to the shield 7. The metal strip 13 can, for example, be soldered to the shield 7 or connected in one piece.

Wie sich insbesondere aus FIG 3 ergibt, sind die Kontaktbuchsen 14 des Steckverbinders 6 mit ihren Kontaktenden 14' gegen einen in FIG 3 nicht dargestellten Gegensteckverbinder gerichtet. Der Gegensteckverbinder korrespondiert selbstverständlich mit dem Steckverbinder 6 und weist die mit den Kontaktbuchsen 14 korrespondierenden Kontaktstecker auf.As can be seen in particular from FIG. 3, the contact sockets 14 of the connector 6 are directed with their contact ends 14 ′ against a mating connector, not shown in FIG. The mating connector naturally corresponds to the connector 6 and has the contact connector corresponding to the contact socket 14.

Die Kontaktbuchsen 14 sind derart in dem elektrisch isolierenden Grundkörper 9 gehalten, daß die Frontfläche 8 vor dem Verbinden des Gegensteckverbinders mit dem Steckverbinder 6 zwischen den Kontaktbuchsen 14 und den Kontaktsteckern des Gegensteckverbinders angeordnet ist. Selbstverständlich weist der Grundkörper 9 inclusive Frontfläche 8 daher vor den Kontaktbuchsen 14 Durchbrüche 15 auf, da ansonsten der Gegensteckverbinder nicht mit dem Steckverbinder 6 verbunden werden könnte.The contact sockets 14 are held in the electrically insulating base body 9 such that the front surface 8 is arranged between the contact sockets 14 and the contact plugs of the mating connector before the mating connector is connected to the connector 6. Of course, the base body 9 including the front surface 8 therefore has openings 15 in front of the contact sockets 14, since otherwise the mating connector could not be connected to the connector 6.

Gemäß FIG 4 kann anstelle des Metallstreifens 13 auch die Frontfläche 8 mit einer metallischen Beschichtung 16 versehen sein. Auch die metallische Beschichtung 16 ist mit der Abschirmung 7 verbunden und so auf Massepotential gelegt. Zur Vermeidung von Kurzschlüssen zwischen der metallischen Beschichtung 16 und den Kontaktsteckern des auch in FIG 4 nicht dargestellten Gegensteckverbinders weist die metallische Beschichtung 16 an den Durchbrüchen 15 Ausnehmungen 17 auf, deren Durchmesser D größer als der Durchmesser d der Durchbrüche 15 ist.According to FIG. 4, the front surface 8 can also be provided with a metallic coating 16 instead of the metal strip 13. The metallic coating 16 is also connected to the shield 7 and is thus connected to ground potential. In order to avoid short circuits between the metallic coating 16 and the contact plugs of the mating connector (also not shown in FIG. 4), the metallic coating 16 has recesses 17 on the openings 15, the diameter D of which is greater than the diameter d of the openings 15.

Der in die speicherprogrammierbare Steuerung eingebaute Steckverbinder 6 gemäß FIG 2 und 3 bzw. gemäß FIG 4 genügt der strengen Schutzvorschrift IEC 801-2. Darüber hinaus ist er mechanisch und elektrisch voll kompatibel zum bisher verwendeten Standardsteckverbinder. Er ist leicht und kostengünstig herzustellen. Die erfindungsgemäße Lösung ist robust und störunanfällig. Schutzbeschaltungen für die Kontaktbuchsen 14 sind nicht nötig und benötigen folglich auch keinen Platz. Dieser Platz steht dadurch anderweitig zur Verfügung.The plug-in connector 6 according to FIGS. 2 and 3 or according to FIG. 4 built into the programmable logic controller complies with the strict protection standard IEC 801-2. In addition, it is mechanically and electrically fully compatible with the previously used standard connector. It is easy and inexpensive to manufacture. The solution according to the invention is robust and not susceptible to faults. Protective circuits for the contact sockets 14 are not necessary and consequently do not require any space. This space is therefore available elsewhere.

Außer bei speicherprogrammierbaren Steuerungen, insbesondere sicherheitsgerichteten speicherprogrammierbaren Steuerungen, ist der erfindungsgemäße Steckverbinder auch in der Telekommunikationstechnik verwendbar.In addition to programmable logic controllers, in particular safety-related programmable logic controllers, the connector according to the invention can also be used in telecommunications technology.
