Description

Die Erfindung bezieht sich auf einen mehrpoligen elektrischen Stecker, welcher ein Steckergehäuse, einen vorne daraus herausragenden Standardstecker mit einem Trägerblock aus Kunststoff für einen elektrischen Kontaktteil und ein hinten in das Steckergehäuse geführtes, mehradriges elektrisches Anschlusskabel für die elektrischen Kontakte umfasst.The invention relates to a multi-pole electrical Connector, which is a connector housing, one in front of it outstanding standard plug with a carrier block made of plastic for an electrical contact part and a Multi-core electrical lead into the rear of the connector housing Includes connection cable for the electrical contacts.

Es sind zahlreiche verschiedene Fabrikate von Steckern bzw. Steckverbindungseinrichtungen für Schwachstromanlagen auf dem Markt, insbesondere für elektrische Anschlüsse an Kommunikationshaupt- und Peripheriegeräte, beispielsweise ISDN, Telefon, Terminal und Modem, sowie PC, Host oder Datennetzwerksysteme. Die Steckverbindungseinrichtungen umfassen in der Regel vier bis 16, aber auch mehr Pole, wie die Kontakte auch genannt werden. Unerlaubte, unrichtige, falsche, nicht systemkonforme, artfremde oder systemschädliche Anschlüsse werden seit langem vermieden, indem die Steckverbinder bestimmte geometrische Formen und/oder äussere Abmessungen haben.There are numerous different makes of plugs or Connector devices for low-voltage systems the market, especially for electrical connections to main communication and peripherals, for example ISDN, telephone, terminal and modem, as well as PC, host or data network systems. The connector devices include usually four to 16, but also more poles, like the contacts also be called. Illegal, incorrect, wrong, Connections that do not conform to the system, are of a different type or are harmful to the system have long been avoided by the connector certain geometric shapes and / or external dimensions to have.

Das Aufsetzen von unerwünschten Steckern kann auch durch eine Codierung vermieden werden. Bezüglich der äusseren Abmessungen von Stecker und Steckdoseneinsatz ist das Steckverbindersystem für bestimmte Polzahlen einheitlich standardisiert ausgebildet. Eine besonders vorteilhafte Ausführungsform ist in der EP,A1 0573396 beschrieben, wo das Codiersystem und das Kontaktsystem von Dose und Stecker in Steckrichtung räumlich getrennt und unabhängig voneinander sind. Mit einem derartigen Codiersystem können bei gleicher geometrischer Form und/oder äusseren Abmessungen eine grosse Zahl von Kombinationsmöglichkeiten genutzt werden.Putting on unwanted plugs can also be done by coding can be avoided. Regarding the outer dimensions The connector system is the plug and socket insert standardized for certain number of poles educated. A particularly advantageous embodiment is described in EP, A1 0573396, where the coding system and the contact system of socket and plug in Plug direction spatially separated and independent of each other are. With such a coding system, the same geometric shape and / or outer dimensions a large Number of possible combinations can be used.

Die Codierung kann durch eine spezielle Farbgebung von Stecker und zugehörender Dose ersetzt, unterstützt oder ergänzt werden. Heute stehen bis zu 30 verschiedene Kennfarben zur Verfügung, welche ein falsches Stecken sofort augenfällig machen. Eine zusätzliche Codierung schliesst Fehlmanipulationen zum vornherein aus. Am bequemsten ist die Zuordnung einer Farbe zu einem bestimmten Code. Selbstverständlich können einer Farbe auch verschiedene Codes zugeordnet werden, was praktisch unbeschränkte Kombinationsmöglichkeiten zulässt.The coding can be done by a special coloring of Replaces, supports or supplements the plug and associated socket become. Today there are up to 30 different identification colors are available, which immediately catches a wrong insertion do. Additional coding prevents incorrect manipulation from the outset. The assignment is most convenient a color to a specific code. Of course can also assign different codes to one color be what practically unlimited combination possibilities allows.

Ein wesentlicher Nachteil dieser Vielfalt besteht darin, dass eine grosse Anzahl von Kabeln mit beidendigen Steckern an Lager gehalten werden muss. Damit verbunden sind entsprechend hohe Investitionen an Kabel- und Steckermaterial, sowie Kosten für Lagerraum und Lagerbewirtschaftung.A major disadvantage of this diversity is that that a large number of cables with both ends plugs must be kept in stock. Are connected accordingly high investments in cable and connector material, as well Storage and warehouse management costs.

Der Erfindung liegt die Aufgabe zugrunde, einen mehrpoligen elektrischen Stecker der eingangs genannten Art zu schaffen, welcher bei unverändert grosser Verwendungsvielfalt die Logistikprobleme auf einen Bruchteil reduziert.The invention has for its object a multi-pole to create electrical plugs of the type mentioned at the beginning, which with unchanged great variety of uses Logistics problems reduced to a fraction.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass das Steckergehäuse in einen kabelseitigen Steckergehäuseabschluss und eine auswechselbare Steckergehäusehülse aufgeteilt ist, welche in einer dem Steckergehäuseabschluss anliegenden Position lösbar zu fixieren und vollständig zugentlastet ist. Spezielle und weiterführende Ausführungsformen der Erfindung sind Gegenstand von abhängigen Patentansprüchen.The object is achieved in that the Connector housing in a cable-side connector housing termination and split an interchangeable connector housing sleeve which is in a contact with the connector housing termination Position can be releasably fixed and completely relieved of strain is. Special and further embodiments the invention are the subject of dependent claims.

Kabelmantel, Steckergehäuseabschluss und Trägerblock des Standardsteckers, welche alle aus Kunststoff bestehen, sind zweckmässig in einer unauffälligen, neutralen Farbe gehalten, ebenso eine allfällige, mit dem Steckergehäuseabschluss einstückig ausgebildete Tülle, welche dem Knickschutz des Kabels im Uebergangsbereich zum Stecker dient.Cable sheath, connector housing termination and carrier block of the Standard plugs, which are all made of plastic suitably kept in an inconspicuous, neutral color, also a possible one with the connector housing termination one-piece grommet, which protects the kink of the cable in the transition area to the plug.

Die auswechselbare Steckergehäusehülse, ebenfalls aus Kunststoff, ist mit Vorteil farbig ausgebildet, wobei wenigstens 15 sich deutlich voneinander unterscheidende Farben zur Verfügung stehen. Sie ist vorzugsweise einteilig ausgebildet und über den elektrischen Kontaktteil des Standardsteckers schiebbar.The interchangeable connector housing sleeve, also made of Plastic is advantageously colored, at least 15 clearly different colors be available. It is preferably formed in one piece and via the electrical contact part of the standard plug slidable.

Die heute verfügbaren Anschlusskabel mit zwei endständigen Steckern sind erfindungsgemäss modular zerlegt. Ein in der Praxis völlig hinreichendes Sortiment besteht aus z.B. fünf verschiedenen Kabellängen und Steckergehäusehülsen in 15 Farben. Statt 75 vorgefertigte Kabel mit beidends gebrauchsfertigen Steckern müssen derart nur noch fünf Kabel und 15 verschiedenfarbige Steckergehäusehülsen an Lager gehalten werden. Diese können mit einem einfachen Handgriff montiert werden und das fertige Kabel ist durch eine Kennfarbe charakterisiert, wie dies bisher nur mit grossem Lageraufwand möglich war.The connection cables available today with two terminals According to the invention, plugs are modularly disassembled. An Indian In practice, a sufficiently wide range consists of e.g. five various cable lengths and connector housing sleeves in 15 Colours. Instead of 75 prefabricated cables with both ends ready for use In this way, plugs only need five cables and 15 different colored connector housing sleeves kept in stock become. These can be assembled with a simple handle and the finished cable is characterized by a color code, as was previously only possible with a large storage effort was.

Die farbigen Steckergehäusehülsen können platzsparend in verhältnismässig kleinen Boxen oder dgl. gelagert werden. Anschlusskabel, Steckergehäuseabschlüsse, Tüllen und Trägerblöcke für einen elektrischen Kontaktteil sind neutral gefärbt als uniforme Einheit für sämtliche Kennfarben einsetzbar.The colored connector housing sleeves can save space in relatively small boxes or the like can be stored. Connection cables, connector housings, grommets and support blocks for an electrical contact part are neutral dyed as a uniform unit for all identification colors.

Die lösbare Fixierung der auswechselbaren Steckergehäusehülse erfolgt zweckmässig mit einer an sich bekannten, heute in breitem Umfang verwendeten Clipverbindung, beispielsweise einer Verrastung einer Einschnappnase in einer Nut. Es sind jedoch auch druckknopfartige Verbindungen, Bajonettverschlüsse, Klettverschlüsse usw. einsetzbar, wesentlich ist eine sichere, Steckergehäuseabschluss und Steckergehäusehülse in aneinanderliegender Position haltende Verbindung, welche rasch und problemlos wieder gelöst werden kann.The detachable fixation of the exchangeable connector housing sleeve expediently takes place with a known today widely used clip connection, for example a snap-in catch in a groove. It but are also snap fasteners, bayonet locks, Velcro fasteners etc. can be used, essential is a secure, connector housing termination and connector housing sleeve connection holding in adjacent position, which can be solved quickly and easily.

Nach einer ersten Variante des erfindungsgemässen Steckers ist der Steckergehäuseabschluss, vorzugsweise mit einer Tülle, und der Trägerblock des Standardsteckers einstückig auf den endständigen Kabelmantel des Anschlusskabels aufgespritzt. Diese aufgespritzte Einheit ist mit der Steckergehäusehülse verrastbar, beispielsweise indem zwei gegenüberliegende Federschenkel der Steckergehäusehülse mit einer Einrastnase in zwei gegenüberliegenden Nuten des Trägerblocks für den elektrischen Kontaktteil einrasten. Dabei sind die Einrastnasen und die Nuten so positioniert, dass die Steckergehäusehülse am Steckergehäuseabschluss anliegt, beispielsweise indem zwei ebene Flächen leicht aneinandergedrückt sind.According to a first variant of the connector according to the invention is the connector housing termination, preferably with a Grommet, and the carrier block of the standard connector in one piece sprayed onto the terminal cable sheath of the connection cable. This sprayed-on unit is with the connector housing sleeve lockable, for example by two opposite Spring leg of the connector housing sleeve with a Snap in two opposite grooves of the support block for the electrical contact part. Here the locking lugs and the grooves are positioned so that the Connector housing sleeve is in contact with the connector housing termination, for example by lightly pressing two flat surfaces together are.

Nach einer zweiten Variante ist das Anschlusskabel lediglich abgelängt, ohne weitere Aufspritzteile. Der Steckergehäuseabschluss ist, vorzugsweise mit angeformter Tülle als Knickschutz für das Kabel im Uebergang zum Stecker, aufschiebbar ausgebildet. Dieser aufschiebbare Teil hat die neutrale Farbe des Anschlusskabels, was die Lagerhaltung vereinfacht, weil alle Steckergehäuseabschlüsse die gleiche Farbe haben. Der Steckergehäuseabschluss umfasst Mittel zum lösbaren Verbinden mit einer farbigen Steckergehäusehülse, welche ihrerseits lösbar mit dem Standardstecker verbunden ist. Diese Mittel können beispielsweise in Richtung des Kabelendes abkragende Federschenkel zum Verrasten mit der Steckergehäusehülse sein, welche ihrerseits mit dem Standardstecker verrastet ist.According to a second variant, the connection cable is merely cut to length, without further injection parts. The connector housing termination is, preferably with a molded spout as kink protection for the cable in the transition to the plug, can be pushed on educated. This slide-on part has the neutral color the connection cable, which simplifies storage, because all connector housings are the same color. The connector housing cover includes means for detachable Connect with a colored connector housing, which is in turn detachably connected to the standard plug. These means can, for example, in the direction of the cable end cantilever spring legs for locking with the connector housing sleeve be, which in turn with the standard plug is locked.

Bei beiden Varianten sind die charakteristisch farbigen, einstückig ausgebildeten Steckergehäusehülsen mit einem oder wenigen Handgriffen auswechselbar. Selbstverständlich kann an einem Anschlusskabel einends die eine Variante, andernends die andere Variante ausgebildet sein, wesentlich ist die gleiche Kennfarbe. Dies hat den Vorteil, dass die Vorteile der ersten Variante an einem Kabelende genutzt werden können. Das andere Kabelende kann wenn notwendig oder wünschenswert beliebig gekürzt und dann der zweite Stecker mit der gleichen charakteristischen Kennfarbe montiert werden.In both variants, the characteristic colored, integrally formed connector housing sleeves with a exchangeable in a few simple steps. Of course can be a variant on one connection cable, the other the other variant should be designed, essential is the same color code. This has the advantage that the Advantages of the first variant can be used at one end of the cable can. The other end of the cable can if necessary or desirable shortened as desired and then the second connector with the same characteristic color code.

Die richtige Zuordnung eines Steckers zu einer Steckdose kann bei gleicher geometrischer Form und Abmessung des Steckers absolut sicher gemacht werden, indem ein an sich bekanntes Codiersystem eingesetzt wird, vorzugsweise gemäss der EP,A1 0573396. Die Codierkämme sind am Aussenmantel der Steckgehäusehülse angeformt. Für jede Variante wird eine entsprechend modifizierte Spritzform hergestellt. Die Anzahl Spritzformen könnte auch vermindert und ein oder mehrere Codierkämme individuell abgetrennt werden. Bei sechs Kamm-/Nutpaaren ergeben sich 31 Codiermöglichkeiten. Werden auf den Schmalseiten von grösseren Steckern statt drei je vier Codierkämme angeordnet, steigt die Zahl der Variationsmöglichkeiten bereits auf 57, verdoppelt sich also nahezu.The correct assignment of a plug to a socket can with the same geometric shape and dimension of the Plugs can be made absolutely safe by one in itself known coding system is used, preferably according to EP, A1 0573396. The coding combs are on the outer jacket of the Plug-in housing molded. For each variant there is one accordingly modified injection mold manufactured. The number Injection molding could also be reduced and one or more Coding combs can be separated individually. At six Comb / groove pairs result in 31 coding options. Become on the narrow sides of larger plugs instead of three each Four coding combs arranged, the number of possible variations increases already at 57, almost doubling.

Eine Steckergehäusehülse ohne Codierkämme oder mit vollständig abgetrennten Codierkämmen kann in jeden codierten oder uncodierten Steckdoseneinsatz gesteckt werden.A connector housing sleeve without coding combs or with complete separate coding combs can be encoded in any or uncoded socket insert.

Es hat sich im industriellen Einsatz als vorteilhaft erwiesen, einer bestimmten Codiervariante eine bestimmte Kennfarbe zuzuordnen, obwohl dadurch das Variationspotential nicht voll ausgeschöpft wird.It has proven to be advantageous in industrial use a certain coding color for a certain coding variant assign, although this means the potential for variation is not fully utilized.

Obwohl codierte Steckergehäusehülsen im Zusammenwirken mit entsprechenden Steckdoseneinsätzen die Vielfalt von gesicherten Steckverbindersystemen für mehrpolige elektrische Stecker gemäss vorliegender Erfindung mit einfachsten Mitteln bedeutend erweitern, wird dadurch die Anzahl verschiedener Steckergehäusehülsen lediglich verdoppelt, was das Lagervolumen nur unbedeutend vermehrt. Selbstverständlich können auch ausschliesslich codierte Steckergehäusehülsen gelagert werden, welche durch das Abtrennen von allen Codierkämmen zur uncodierten Hülse werden.Although coded connector housing sleeves interact with corresponding socket inserts the variety of secured Connector systems for multi-pole electrical Plug according to the present invention with the simplest means significantly expand the number of different Connector housing sleeves just doubled what that Storage volume increased only slightly. Of course can also be used exclusively for coded connector housing sleeves be stored, which by separating all coding combs become an uncoded shell.

Zur Sicherung der Stecker in einem Steckdoseneinsatz weist der Standardstecker vorzugsweise einen vom Kontaktteil nach hinten abstehenden, federnden Verriegelungsbügel mit Einrastnasen auf. Beim Einführen des Steckers in den Steckdoseneinsatz verrastet dieser Bügel nach dem Erreichen der Endposition automatisch. Zum Lösen wird dieser Verriegelungsbügel mit einem Finger gegen den Standardstecker gedrückt, und der entriegelte Stecker herausgezogen, was jedoch nicht immer einfach zu bewerkstelligen ist.To secure the plug in a socket insert the standard connector preferably one from the contact part protruding spring-loaded locking bracket with snap-in lugs on.
