Description

Die Erfindung betrifft einen Schalterstecker mit in Kontaktkammern eines Isolierkörpers angeordneten Kontaktfedern, wobei Kontaktmesser eines entsprechenden Gegensteckers in die Kontaktkammern einführbar sind und dabei mit den Kontaktfedern in Kontakt gelangen und bei dem mindestens eine federelastische Kurzschlußbrücke vorgesehen ist, die zwei benachbarte Kontaktfedern bei nicht gestecktem Gegenstecker kurzschließt und wobei beim Einführen der Messerkontakte in die Kontaktkammern der Kurzschluß durch ein auf die Kurzschlußbrücke einwirkendes, elastisches Betätigungsteil aufgehoben wird.The invention relates to a switch connector with in contact chambers Insulating body arranged contact springs, contact blades of a corresponding Mating connector can be inserted into the contact chambers and thereby come into contact with the contact springs and the at least a resilient short-circuit bridge is provided, the two adjacent Contact springs short-circuit when the mating connector is not plugged in and where the short circuit when inserting the knife contacts into the contact chambers by an elastic actuating part acting on the short-circuit bridge will be annulled.

Derartige Schalterstecker werden in elektronischen Systemen verwendet, in denen beim Trennen einer Steckverbindung ausgewählte Kontakte bzw. Kontaktelemente des einen Steckverbinders, nämlich des Schaltersteckers, nicht als "offene" Kontakte (Signalleitungen) enden dürfen, sondern miteinander verbunden werden müssen.Such switch plugs are used in electronic systems in contacts or contacts selected when disconnecting a connector Contact elements of one connector, namely the switch connector, not end as "open" contacts (signal lines), but with each other need to be connected.

Ein derartiger Schalterstecker ist aus der US 5 259 776 A bekannt. Dabei sind zwischen benachbarten Kontaktfedern U-förmige Kurzschlußbrücken angeordnet, an deren Schenkeln nicht leitende Kunststoffteile befestigt sind. Beim Einführen von Kontaktmessern in den Schalterstecker wirken diese auf die Kunststoffteile der Kurzschlußbrücken ein, so daß die Kurzschlußbrükken von den Kontaktfedern entfernt werden. Bei dem bekannten Schalterstecker ist der Isolierkörper zweiteilig aus einem Basisteil und einem Deckelteil ausgebildet, damit die Kurzschlußbrücken in entsprechende Aufnahmen im Basisteil eingesetzt werden können. Durch die bauartbedingten geringen Abmessungen der Kunststoffteile ist eine Aufhebung des Kurzschlusses nicht immer gewährleistet, wenn der Gegenstecker, d. h. dessen Kontaktmesser nicht genau zentrisch und senkrecht in den Schalterstecker gesteckt wird.
Weiterhin genügt die bei schief eingeführten Kontaktmessern verbleibende geringere Luft- und Kriechstrecke zwischen leitfähigen Teilen oftmals nicht den Anforderungen.Such a switch connector is known from US 5 259 776 A. Here, U-shaped short-circuit bridges are arranged between adjacent contact springs, on the legs of which non-conductive plastic parts are fastened. When inserting contact blades into the switch connector, these act on the plastic parts of the short-circuit bridges, so that the short-circuit bridges are removed from the contact springs. In the known switch connector, the insulating body is formed in two parts from a base part and a cover part, so that the short-circuit bridges can be inserted into corresponding receptacles in the base part. Due to the design-related small dimensions of the plastic parts, a cancellation of the short circuit is not always guaranteed if the mating connector, ie its contact blade, is not inserted exactly centrally and vertically into the switch connector.
Furthermore, the smaller clearance and creepage distance between conductive parts remaining when contact blades are inserted at an angle often does not meet the requirements.

Aus der EP-A-0 462 084 ist weiterhin ein Schalterstecker bekannt, der eine federelastische Kurzschlußbrücke aufweist, die beim Stecken eines Gegensteckers durch dessen Kontaktelemente betätigt wird. Dabei ist innerhalb des Schaltersteckers ein elastisches Betätigungsteil vorgesehen, das auf die Kurzschlußbrücke einwirkt.From EP-A-0 462 084 a switch connector is also known, the one Has springy short-circuit bridge, when plugging a mating connector is actuated by the contact elements. Doing is inside the switch connector provided an elastic actuator that on the Short-circuit bridge acts.

Daneben ist es aus der EP-A-0 430 267 bekannt, Kontakte eines elektrischen Steckverbinders aus Kunststoffmaterial auszubilden und das Kunststoffmaterial mit einem leitenden Überzug zu versehen.In addition, it is known from EP-A-0 430 267, contacts of an electrical Form connector from plastic material and the plastic material to be provided with a conductive coating.

Der Erfindung liegt die Aufgabe zugrunde, einen Schalterstecker der eingangs genannten Art dahingehend auszubilden, daß ein einteiliger Isolierkörper verwendet werden kann und daß die Funktionssicherheit des Schaltersteckers erhöht wird.The invention has for its object a switch connector of the beginning mentioned type in that a one-piece insulating body can be used and that the reliability of the switch connector is increased.

Diese Aufgabe wird dadurch gelöst, daß der Isolierkörper einteilig ausgebildet ist, daß die Kurzschlußbrücke aus federelastischem, leitfähigem Material in eine zur Oberseite des Isolierkörpers hin offene Ausnehmung zwischen zwei Kontaktkammern eingesetzt ist, wobei seitliche Kontaktarme der Kurzschlußbrücke in die Kontaktkammern hineinragen und federnd an den Kontaktschenkeln der Kontaktfedern anliegen, daß das Betätigungsteil aus Kunststoffmaterial besteht und im Eingangsbereich der Kontaktkammern vorgesehen ist, daß der Isolierkörper in der Oberseite eine Ausnehmung aufweist, in welcher ein Befestigungsteil des Betätigungsteils eingeführt ist, daß das Befestigungsteil eine Klappe aufweist, welche mit dem Befestigungsteil durch ein Filmscharnier schwenkbar verbunden ist, daß das Betätigungsteil derart in die jeweilige Kontaktkammer hineinragt, daß die Unterseite der Klappe auf oberen Bereichen der Kontaktarme der Kurzschlußbrücke aufliegt, und daß ein eingeführtes Kontaktmesser auf die Oberseite des Betätigungsteils drückt, wobei das Betätigungsteil eine Kraft auf die Kurzschlußbrücke ausübt und diese so bewegt, daß der Kurzschluß aufgehoben wird.This object is achieved in that the insulating body is formed in one piece is that the short circuit bridge made of resilient, conductive material is inserted into a recess open to the top of the insulating body between two contact chambers, wherein lateral contact arms of the short-circuit bridge protrude into the contact chambers and resiliently rest on the contact legs of the contact springs, that the actuator is made of plastic material and in the entrance area the contact chambers is provided that the insulating body has a recess in the top has, in which a fastening part of the actuating part is inserted is that the fastening part has a flap which with the Fastening part is pivotally connected by a film hinge that the actuating part protrudes into the respective contact chamber such that the Bottom of the flap on the upper areas of the contact arms of the shorting bar rests, and that an inserted contact knife on the Presses top of the actuator, the actuator a force exercises on the short-circuit bridge and moves it so that the short-circuit will be annulled.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 9 angegeben. Advantageous embodiments of the invention are in claims 2 to 9 specified.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß durch das separat vorgesehene Betätigungsteil und dessen Anordnung auch bei ggf. schräg eingeführten Kontaktmessern des Gegensteckers zum einen eine sichere Aufhebung des Kurzschlusses zwischen zwei Kontaktfederenden des Schaltersteckers erzielt wird, und zum anderen sind auch dabei die anwendungsgemäß erforderlichen Kriech- und Luftstrecken zwischen leitfähigen Teilen der Steckverbindung stets gewährleistet, so daß die Funktionssicherheit insgesamt erhöht wird. The advantages achieved by the invention are in particular that through the separately provided actuating part and its arrangement also if contact blades of the mating connector are inserted at an angle, on the one hand safe cancellation of the short circuit between two contact spring ends of the switch connector is achieved, and on the other hand, the required creepage and clearance distances between conductive Parts of the connector always guaranteed, so that the functional reliability is increased overall.

Ein weiterer Vorteil besteht darin, daß der Isolierkörper des Schaltersteckers einteilig ausgebildet sein kann und daß als Gegenstecker ein unveränderter, auch für Steckverbindungen ohne Schaltelemente bereits bekannter und angewendeter Messersteckverbinder verwendet werden kann.
Ferner besteht ein weiterer Vorteil des erfindungsgemäßen Schaltersteckers darin, daß die verwendeten Kontaktelemente an sich bekannte und auch für andere Anwendungen/Steckverbinder bereits lagermäßig vorhandene Doppelkontaktfedern sind und die einseitig kontaktierenden Kontaktfedern durch einfaches Entfernen eines Federschenkels einer Doppelkontaktfeder hergestellt werden können.Another advantage is that the insulating body of the switch connector can be formed in one piece and that an unchanged knife connector can also be used as the mating connector, also known and used for plug connections without switching elements.
A further advantage of the switch connector according to the invention is that the contact elements used are known double contact springs that are already in stock for other applications / connectors, and the contact springs contacting on one side can be produced by simply removing a spring leg of a double contact spring.

Der in der Fig. 1 dargestellte Schalterstecker besteht im wesentlichen aus einem Isolierkörper 1, der mit Kontaktkammern 2 versehen ist, in die Kontaktelemente 3 von der Unterseite 4 her eingeschoben und verankert sind, wobei die Kontaktelemente als Federkontakte ausgebildet sind. Die Kontaktelemente sind in Reihen und Spalten angeordnet, und die mechanische Ausbildung / Steckgeometrie des Schaltersteckers ist so, daß ein entsprechender Gegenstecker mit Messerkontakten damit steckbar ist. Die Steckgeometrie ist insgesamt entsprechend handelsüblicher DIN-Steckverbinder ausgebildet. Zwischen zwei benachbarten Kontaktkammern ist eine Kurzschlußbrücke eingefügt, die bei nicht eingeführten Messerkontakten die Federkontakte dieser Kammer kurzschließt und die beim Einführen der Messerkontakte von den Federkontakten entfernt wird, so daß der Kurzschluß aufgehoben wird.
Die Fig. 2 zeigt eine vergrößerte Aufsicht auf einen Teil des Schalterstekkers zur Verdeutlichung von Einzelheiten, und die Schnittansichten der Fig. 3, 3A und 4 zeigen die Anordnung der Kontaktelemente 3, der Kurzschlußbrücke 5 und eines Betätigungsteiles 6 innerhalb des Isolierkörpers 1.
Wie bereits erwähnt, ist der Isolierkörper mit Kontaktkammern 2 versehen, in die Kontaktelemente 3 eingeschoben sind. Zwischen zwei benachbarten Kontaktkammern ist eine Ausnehmung 7 eingeformt, die zur Oberseite 8 des Isolierkörpers hin offen ist. In diese Ausnehmung ist die Kurzschlußbrücke 5, die in der Fig. 7 dargestellt ist, eingeschoben. Die Kurzschlußbrücke aus elektrisch leitfähigem Material ist etwa U-förmig gebogen und weist einen Befestigungsschenkel 9 und einen Kontaktschenkel 10 auf.
Der Kontaktschenkel ist dabei federelastisch in bezug auf den Befestigungsschenkel. An dem Befestigungsschenkel sind Rastvorsprünge 11 ausgebildet, die zur Verankerung der Kurzschlußbrücke in der Ausnehmung 7 vorgesehen sind und sich beim Einschieben in deren Wände eingraben. Das obere Ende 12 des Kontaktschenkels ist T-förmig gestaltet, wobei zwei seitliche Kontaktarme 13 ausgebildet sind. Nach dem Einschieben der Kurzschlußbrücke in die Ausnehmung 7 des Isolierkörpers, sind die Kontaktarme in einer solchen Position, daß sie federnd gegen die Kontaktschenkel 14 der Kontaktelemente 3' drücken und die beiden benachbarten Kontaktelemente 3' kurzschließen. Hierbei sei noch erwähnt, daß die "normalen" Kontaktelemente 3 als doppelseitig kontaktierende Federkontakte mit jeweils zwei Kontaktschenkeln ausgebildet sind, während die als Schaltkontakte verwendeten Kontaktelemente 3' als einseitig kontaktierende Kontaktfedern mit jeweils nur einem Kontaktschenkel ausgebildet sind.
Zur Betätigung der Schaltkontakte, d. h. zur Aufhebung des Kurzschlusses beim Einführen eines Gegensteckers ist ein Betätigungsteil 6 aus Kunststoffmaterial vorgesehen, das in den Fig. 5 und 6 dargestellt ist. Das Betätigungsteil 6 ist mit einem Befestigungsteil 19 durch ein Filmscharnier 15 verbunden. Das Befestigungsteil weist dabei seitliche Anformungen 16 auf, die zur Befestigung und Halterung des Betätigungsteils in einer entsprechend geformten Ausnehmung 17 in der Oberseite 8 des Isolierkörpers dient. Nach dem Einfügen des Befestigungsteils in diese Ausnehmung ragt dieses in die zwei benachbarten Kontaktkammern 2 hinein, wobei die Unterseite des Betätigungsteils auf den oberen Bereichen der Kontaktarme 13 der Kurzschlußbrücke aufliegt (Fig. 3). Hierzu weisen die Kontaktarme entsprechende Rundungen/Abbiegungen zur Bildung von Auflagebereichen auf. Die Oberseite (20) des Betätigungsteils ist vorzugsweise so ausgebildet, daß nach dem Einfügen dieses Teils in den Isolierkörper bzw. die Kontaktkammern die Geometrie des Einführbereiches der Kontaktkammern mit Schaltkontakten der Geometrie der Einführbereiche der Kontaktkammern mit normalen Kontakten entspricht.
Beim Einstecken eines Gegensteckers treten die Messerkontakte 18 in die Kontaktkammern 2 ein (Fig. 3A). Hierbei Treffen die den Schaltkontakten 3' zugeordneten Messerkontakte zunächst auf die Oberseite des Betätigungsteils 6 und drücken dieses nach unten. Dabei übt die Unterseite des Betätigungsteils eine Kraft auf die Kontaktarme 13 der Kurzschlußbrücke 5 aus und drückt diese derart zur Seite, daß die Verbindung zwischen den benachbarten Kontaktelementen 3' getrennt wird. Anschließend gelangen die Messerkontakte in Kontakt mit den Kontaktschenkeln der Kontaktelemente 3'.
Beim Entfernen des Gegensteckers drückt der federnde Kontaktschenkel 10 der Kurzschlußbrücke das Betätigungsteil wieder nach oben zurück, und die Kontaktarme der Kurzschlußbrücke gelangen wieder in Kontakt mit den entsprechenden Kontaktelementen 3'.
Die vorstehende Beschreibung geht von einer Kurzschlußbrücke aus, die aus federelastischem, leitendem Blechmaterial hergestellt ist. Ggf. kann jedoch auch vorgesehen sein, daß die Kurzschlußbrücke aus federelastischem Kunststoffmaterial hergestellt ist, wobei entweder das Kunststoffmaterial durch entsprechende Zusätze elektrisch leitfähig gemacht ist oder einen leitenden Überzug/eine metallische Galvanisierung aufweist, wobei diese zumindest im Bereich der Kontaktarme 13 vorgesehen ist. Bei einer Kurzschlußbrücke aus Kunststoffmaterial kann alternativ auch vorgesehen sein, daß als leitendes Verbindungsstück ein metallisches Kontaktstück im Bereich der Arme an dieser befestigt ist.The switch connector shown in Fig. 1 consists essentially of an insulating body 1, which is provided with contact chambers 2, into which contact elements 3 are inserted and anchored from the bottom 4, the contact elements being designed as spring contacts. The contact elements are arranged in rows and columns, and the mechanical design / plug geometry of the switch plug is such that a corresponding mating plug with knife contacts can be plugged in with it. The overall plug-in geometry is designed in accordance with standard DIN connectors. A short-circuit bridge is inserted between two adjacent contact chambers, which short-circuits the spring contacts of this chamber when the knife contacts are not inserted, and which is removed from the spring contacts when the knife contacts are inserted, so that the short-circuit is removed.
2 shows an enlarged plan view of a part of the switch plug for clarification of details, and the sectional views of FIGS. 3, 3A and 4 show the arrangement of the contact elements 3, the short-circuit bridge 5 and an actuating part 6 within the insulating body 1.
As already mentioned, the insulating body is provided with contact chambers 2, into which contact elements 3 are inserted. A recess 7 is formed between two adjacent contact chambers and is open toward the top 8 of the insulating body. The short-circuit bridge 5, which is shown in FIG. 7, is inserted into this recess. The short-circuit bridge made of electrically conductive material is bent approximately in a U-shape and has a fastening leg 9 and a contact leg 10.
The contact leg is resilient with respect to the mounting leg. On the mounting leg locking projections 11 are formed, which are provided for anchoring the short-circuit bridge in the recess 7 and dig into the walls when inserted. The upper end 12 of the contact leg is T-shaped, two side contact arms 13 being formed. After inserting the shorting bridge into the recess 7 of the insulating body, the contact arms are in such a position that they press resiliently against the contact legs 14 of the contact elements 3 'and short-circuit the two adjacent contact elements 3'. It should also be mentioned that the "normal" contact elements 3 are designed as double-sided contacting spring contacts, each with two contact legs, while the contact elements 3 'used as switching contacts are designed as single-sided contacting contact springs, each with only one contact leg.
An actuating part 6 made of plastic material is provided for actuating the switching contacts, ie for eliminating the short circuit when inserting a mating connector, which is shown in FIGS. 5 and 6. The actuating part 6 is connected to a fastening part 19 by a film hinge 15. The fastening part has lateral projections 16, which are used for fastening and holding the actuating part in a correspondingly shaped recess 17 in the top 8 of the insulating body. After the fastening part has been inserted into this recess, it projects into the two adjacent contact chambers 2, the underside of the actuating part resting on the upper regions of the contact arms 13 of the short-circuit bridge (FIG. 3). For this purpose, the contact arms have corresponding curves / bends to form support areas. The upper side (20) of the actuating part is preferably designed such that, after this part has been inserted into the insulating body or the contact chambers, the geometry of the insertion region of the contact chambers with switching contacts corresponds to the geometry of the insertion regions of the contact chambers with normal contacts.
When a mating connector is inserted, the knife contacts 18 enter the contact chambers 2 (FIG. 3A). Here, the blade contacts assigned to the switching contacts 3 'first hit the top of the actuating part 6 and press it down. The underside of the actuating part exerts a force on the contact arms 13 of the short-circuit bridge 5 and presses them to the side in such a way that the connection between the adjacent contact elements 3 'is separated. The knife contacts then come into contact with the contact legs of the contact elements 3 '.
When the mating connector is removed, the resilient contact leg 10 of the short-circuit bridge pushes the actuating part back upward, and the contact arms of the short-circuit bridge come into contact with the corresponding contact elements 3 'again.
The above description is based on a short-circuit bridge, which is made of resilient, conductive sheet material. Possibly. However, it can also be provided that the short-circuit bridge is made of resilient plastic material, either the plastic material being made electrically conductive by appropriate additives or having a conductive coating / metallic galvanization, this being provided at least in the area of the contact arms 13. In the case of a short-circuit bridge made of plastic material, it can alternatively also be provided that a metallic contact piece is fastened to the arms in the region of the arms as the conductive connecting piece.
