Description

Die Erfindung betrifft einen Steckadapter für ein elektrisches Gerät zum Stecken von elektrischen Zuleitungen auf das Gerät und ein elektrisches Gerät. Bei dem Gerät liegen die Geräteanschlusskontakte in einer Reihe nebeneinander und werden über schraubenlose Klemmvorrichtungen kontaktiert.The invention relates to a plug adapter for an electrical device for plugging electrical leads on the device and an electrical device. In the device, the device connection contacts lie side by side in a row and are contacted via screwless clamping devices.

Mit solchen Klemmvorrichtungen lassen sich massive Adern oder feindrähtige Leiter mit Aderendhülsen oder mit Crimpkontakten anschließen und einfach lösen. Die Anschlusskontakte befinden sich in Klemmkammern, wobei die Anschlusskontakte die Form einer mit einem freien Ende ausgestatteten Kontaktfeder haben. Beim Einschieben einer Zuleitung verklemmt ein freies Ende einer Kontaktfeder mit je einer Zuleitungsader. Die Entfernung der Zuleitung wird ermöglicht, wenn der freie Kontaktfederarm über einen Entkopplungsstößel beaufschlagt wird, so dass der freie Kontaktfederarm von der Zuleitungsader wegbewegt wird. So wird die Verklemmung der Zuleitungsader gelöst.With such clamping devices, solid cores or fine-stranded conductors with ferrules or with crimp contacts can be connected and easily removed. The connection contacts are located in clamping chambers, the connection contacts being in the form of a contact spring equipped with a free end. When inserting a supply line, a free end of a contact spring jams with one supply line each. The removal of the supply line is made possible when the free contact spring arm is acted upon by a decoupling plunger, so that the free contact spring arm is moved away from the supply line wire. In this way the jamming of the lead wire is released.

In der DE 10152347 C1 wird ein Steckadapter für ein Schaltgerät beschrieben. Die Zuleitungen werden in Einspeiseklemmen verrastet. Zur Entnahme der Zuleitungsadern muss ein Werkzeug verwendet werden, mit dem die Einspeiseklemmen zu öffnen sind.

Bei den betrachteten schraubenlosen Klemmanschlüssen handelt es sich um sogenannte Push-in-Kontaktklemmen. Pro Pol am Gerät, bzw. pro Pol der Zuleitung ist am Anschlusskontakt am Gerät ein einzelner als Entriegelvorrichtung ausgebildeter Entkopplungsstößel vorhanden. Die Entkopplungsstößel liegen 90° zur Leiterzugangsrichtung und ragen in der Länge ihres Betätigungshubs aus dem Gehäuse des Geräts in Richtung auf die Oberseite des Geräts heraus. Zur elektrischen und mechanischen Freigabe und Entnahme von in Anschlusskontakte eingeschobene Zuleitungen aus den Anschlusskontakten muss an jedem Anschlusskontakt jeder einzelne Entkopplungsstößel betätigt werden.On the device assigned to the plug adapter, an input-side connection contact is formed on each device pole on a device access side. Several connection contacts are in a row next to each other. The connection contacts are designed as screwless terminal connections into which the supply line for electrical contacting and for the sole mechanical connection is inserted in a fixed manner. The screwless terminal connections considered are so-called push-in contact terminals. There is a single decoupling plunger designed as an unlocking device for each pole on the device or per pole of the supply line at the connection contact on the device. The decoupling plungers are 90 ° to the conductor access direction and protrude in the length of their actuation stroke from the housing of the device towards the top of the device. For the electrical and mechanical release and removal of cables inserted into connection contacts from the connection contacts, each individual decoupling plunger must be actuated on each connection contact.

Der Steckadapter hat etwa prismatischen Aufbau aus isolierendem Formstoff, dessen Oberseite parallel zur Oberseite des Geräts liegt (in gesteckter Position). Am Steckadapter ist eine dem Gerät zugewandte Ausgangsseite und eine dem Gerät abgewandte Zugangsseite für Zuleitungen ausgebildet. Zwischen Ausgangsseite und Zugangsseite verlaufen parallel und nebeneinander liegend Aufnahmekanäle für je eine Zuleitungsader. Die Aufnahmekanäle sind ebenfalls den Geräteanschlusskontakten des Geräts zugeordnet.The plug adapter has a prismatic structure made of insulating molded material, the top of which is parallel to the top of the device (in the inserted position). An outlet side facing the device and an access side facing away from the device for supply lines are formed on the plug adapter. Between the exit side and the access side, there are parallel and side-by-side receiving channels for one supply wire each. The recording channels are also assigned to the device connection contacts of the device.

Der Steckadapter wird in zwei Varianten vorgeschlagen. Eine Variante A als einen ersten, einteiligen Steckadapter. Eine zweite Variante B ist als zweiteiliger Steckadapter ausgebildet. Der zweiteilige Steckadapter besteht aus zwei Teilen: einem Adapteroberteil und einem Adapterunterteil. Beide Varianten des Steckadapters weisen den beweglichen Betätigungsbügel auf.The plug adapter is proposed in two variants. A variant A as a first, one-piece plug adapter. A second variant B is designed as a two-part plug adapter. The two-part plug adapter consists of two parts: an adapter upper part and an adapter lower part. Both versions of the plug adapter have the movable operating bracket.

Am Adapteroberteil befindet sich ein beweglicher Betätigungsbügel als Demontagehilfe oder Entkopplungshilfe. Im eingesteckten Zustand des Steckadapters mit Leitungsadern in das mit schraubenloser Anschlusstechnik (mit Push-in-Klemmen) ausgestattetem Gerät liegt der Betätigungsbügel über der als Entkopplungsstößel ausgebildeten Entriegelvorrichtung. Mit dem Betätigungsbügel können erfindungsgemäß alle Entkopplungsstößel auf einmal gedrückt und die Zuleitungsadern entkoppelt werden. Die Entkopplungsstößel werden durch Niederdrücken des Betätigungsbügels (manuell) ohne ein besonderes Werkzeug erreicht und betätigt. Die Zuleitungsadern werden mit dem Betätigungsbügel entkoppelt; der Steckadapter kann mit den Zuleitungsadern entfernt werden.There is a movable operating bracket on the adapter upper part as a disassembly aid or decoupling aid. When the plug-in adapter with cable wires is inserted into the device equipped with screwless connection technology (with push-in terminals), the actuation bracket lies above the unlocking device designed as a decoupling plunger. According to the invention, all of the decoupling plungers can be pressed at once and the supply wires can be decoupled with the actuating bracket. The decoupling plungers are reached and actuated by pressing down the operating bracket (manually) without a special tool. The supply wires are decoupled with the operating bracket; the plug adapter can be removed with the supply wires.

Der Betätigungsbügel ist ein über ein Filmscharnier (über einen Materialsteg) am Steckadapter angeordnet.The actuating bracket is arranged on the plug adapter via a film hinge (via a material web).

Die Zuleitungen können massive Einzelleiter sein, oder die Enden der Zuleitungen können aus verzinnten Litzen bestehen. Vorzugsweise werden für Litzen Crimpkontakte oder Aderendhülsen als Leiterabschlusselemente eingesetzt sein. Die Zuleitungsadern können Einzeladern oder Doppeladern sein, wobei letztere vorzugsweise Crimpkontakte als Leiterabschlusselemente haben. Es ist daher möglich, mehrere Leiter mit unterschiedlichen Durchmessern auf einmal zu montieren (einzuführen) oder zu demontieren (zu trennen).The leads can be solid individual conductors, or the ends of the leads can consist of tinned strands. Crimp contacts or ferrules are preferably used as conductor termination elements for strands. The supply wires can be single wires or double wires, the latter preferably having crimp contacts as conductor termination elements. It is therefore possible to assemble (insert) or disassemble (separate) several conductors with different diameters at once.

Bei der zweiten Variante B des Steckadapters befinden sich im Adapteroberteil mehrere als Haltebacken ausgebildete Aufnahmemittel, wo die Leitungsadern mit den Leiterabschlusselementen positioniert und gehalten werden. Beim Hineinschieben des Adapteroberteils mit positionierten Leitungen in das Adapterunterteil werden die beweglichen Haltebacken mit den Leitungen verklemmt und durch die Klemm-Schrägen fixiert, die sich im Adapterunterteil befinden.In the second variant B of the plug-in adapter, there are a plurality of receiving means designed as holding jaws in the upper part of the adapter, where the line wires with the conductor termination elements are positioned and held. When the upper part of the adapter is pushed into the lower part of the adapter with the lines positioned, the movable holding jaws are clamped to the lines and fixed by the clamping bevels located in the lower part of the adapter.

Folgende Einzelheiten und Merkmale können einzeln oder miteinander kombiniert - soweit technisch sinnvoll - vorhanden sein.The following details and features can be present individually or combined with one another - as far as technically meaningful.

An der Adapteroberseite oberhalb der Ausgangsseite des Steckadapters der Aufnahmekanäle ist der Betätigungsbügel mittels eines federnden Filmscharniers ausgebildet.On the upper side of the adapter above the outlet side of the plug adapter of the receiving channels, the actuating bracket is formed by means of a resilient film hinge.

Die lichte Weite der Aufnahmekanäle soll so bemessen sein, dass sie gleich groß oder kleiner ist als der Durchmesser der Zuleitungsadern. Mit dieser Maßnahme werden die Zuleitungsadern mit Kraftaufwand klemmend in den Aufnahmekanälen aufgenommen, wobei die Kraft der Klemmung größer ist als die Kraft, mit der die Zuleitungsadern in die Geräteanschlusskontakte steckbar sind. Die Zuleitungsadern können sich beim Stecken nicht verschieben.The clear width of the receiving channels should be such that they are the same size or smaller is the diameter of the lead wires. With this measure, the supply wires are clampingly received in the receiving channels, the force of the clamping being greater than the force with which the supply wires can be plugged into the device connection contacts. The supply wires cannot move when plugged in.

Weiterhin können zur Klemmung der Zuleitungsadern elastisch bewegliche Klemmbacken vorhanden sein, wobei die Klemmbacken über Filmscharniere im Adapteroberteil angeordnet sind. Zur weiteren Fixierung eingeschobener Zuleitungsadern können außerdem Klemmrippen beidseitig auf den Innenseiten der Klemmbacken vorgesehen sein. Die Klemmrippen verlaufen parallel zur Ausrichtung der Aufnahmekanäle definierenden Klemmbacken. Zur Ergänzung der Klemmwirkung können im Adapterunterteil U-förmige Aufnahmeschalen ausgebildet sein. Diese bewegen sich beim Zusammenbau von Adapteroberteil und Adapterunterteil zueinander hin und bewirken eine verstärkte Klemmung.Furthermore, there can be elastically movable clamping jaws for clamping the supply wires, the clamping jaws being arranged in the adapter upper part via film hinges. Clamping ribs can also be provided on both sides of the inside of the clamping jaws to further fix inserted supply wires. The clamping ribs run parallel to the alignment of the clamping channels defining the receiving channels. To complement the clamping action, U-shaped receiving shells can be formed in the lower part of the adapter. These move towards each other when assembling the adapter upper part and the lower adapter part and result in increased clamping.

Die Aufnahmekanäle können zur Aufnahme einer isolierten Einfachlitze oder auch zur Aufnahme einer isolierten Doppellitze ausgebildet sein.The receiving channels can be designed for receiving an insulated single strand or also for receiving an insulated double strand.

Die Aufnahmekanäle können außerdem in besonderer Ausbildung zur Aufnahme eines Zuleitungsadern verpressenden Crimpkontakts ausgebildet sein. In solchen Ausbildungen können Crimpkontakte verwendet werden, in denen zwei einzelne Zuleitungsadern oder eine Doppelader als Leiterabschluss verpresst sind. Beispielsweise würde eine einzige Zuleitungsader (Litze als feindrähtiger Leiter) mit großem Leiterquerschnitt (bis zu 2,5 mm2) oder zwei einzelne Zuleitungsadern mit einem Leiterquerschnitt je etwa 2,5 mm2 des vorgenannten Leiterquerschnitts verwendbar sein.The receiving channels can also be designed in a special embodiment for receiving a crimp contact that presses the lead wires. In such designs, crimp contacts can be used in which two individual lead wires or a double wire are pressed as a conductor termination. For example, a single supply wire (stranded wire as a fine wire) with a large conductor cross section (up to 2.5 mm 2 ) or two individual supply wires with a conductor cross section would each be approximately 2.5 mm 2 of the aforementioned conductor cross section.

Das Adapteroberteil ist in das Adapterunterteil parallel zu den Aufnahmekanälen einschiebbar, wobei an einer Ausgangsseite eines ersten Adapterteils eine Anschlagnase für das andere Adapterteil und an dem andere Adapterteil ein der Anschlagnase zugeordneter Hinterschnitt vorhanden ist.The upper adapter part can be inserted into the lower adapter part parallel to the receiving channels, an abutment nose for the other adapter part being present on an output side of a first adapter part and an undercut assigned to the abutment nose being present on the other adapter part.

Die Ausgangsseiten der Aufnahmekanäle können mit eingeengten Öffnungen ausgebildet sein, die gleich dem Durchmesser eines Leiterabschlusselements oder kleiner sein. Die Öffnungen sind elastisch vergrößerbar, so dass die eingeschobenen Leiteradern in den Öffnungen eingeklemmt werden und auch Halt haben, wenn der Steckadapter nicht am Gerät gesteckt ist.The outlet sides of the receiving channels can be designed with narrowed openings, which are equal to or smaller than the diameter of a conductor termination element. The openings can be enlarged elastically so that the inserted conductor wires are clamped in the openings and also have a hold when the plug adapter is not plugged into the device.

Als Vorteile der Erfindung wird abschließend herausgehoben:

  • Einfaches, sicheres, schnelles Handling beim Kontaktieren und beim Demontieren oder Entkoppeln von mehradrigen Zuleitungen an elektrischen Geräten. Wegen des Vorhandenseins des Betätigungsbügels müssen keine weiteren Werkzeuge benutzt werden,
  • wobei bei Anordnungen im Stand der Technik meistens mehrere Handgriffe vom Bediener, häufig auch beidhändig vorgenommen werden mussten.
Finally, the following are highlighted as advantages of the invention:
  • Simple, safe, quick handling when contacting and when dismantling or decoupling multi-core cables from electrical devices. Due to the presence of the operating bracket, no other tools need to be used,
  • in the case of arrangements in the prior art usually several operations had to be carried out by the operator, often with both hands.

Der Steckadapter ist sicher, da der Bediener keinen direkten Kontakt zu den Zuleitungsadern hat. Die Erfindung kann einfach und schnell bei vorhandenen Zuleitungen und zugehörigen Geräten nachgerüstet werden. Durch die Fixierung der Zuleitungsadern im Steckadapter können Verdrahtungsfehler vermieden werden.The plug adapter is secure because the operator has no direct contact with the supply wires. The invention can be easily and quickly retrofitted to existing supply lines and associated devices. By fixing the supply wires in the plug adapter, wiring errors can be avoided.

Der Steckadapter ist geeignet für alle elektrische Geräte - insbesondere für Schaltgeräte - mit schraubenloser Push-in-Anschlusstechnik, bei denen die Entkopplungsstößel um 90° zur Leiterzugangsrichtung orientiert liegen und frei zugänglich sind (aus dem Gerät herausragen).The plug adapter is suitable for all electrical devices - especially switchgear - with screwless push-in connection technology, in which the decoupling plungers are oriented 90 ° to the conductor access direction and are freely accessible (protrude from the device).

Beschrieben in den Figuren werden zwei Varianten des Steckadapters, wobei für gleiche Teile in den Varianten dieselben Bezugszeichen verwendet werden.Two variants of the plug adapter are described in the figures, the same reference numerals being used for the same parts in the variants.

Die mehrpoligen Steckadapter dienen der Herstellung einer Verbindung zwischen einer elektrischen Zuleitung mit mehreren Zuleitungsadern an ein mehrpoliges Gerät, zur Zuführung der Spannung an das Gerät. In den Figuren werden als typische Ausführung dreipolige Steckadapter dargestellt.The multi-pin plug adapters are used to establish a connection between one electrical supply line with several supply lines to a multi-pole device, for supplying the voltage to the device. In the figures, three-pole plug adapters are shown as a typical embodiment.

Die Steckadapter haben etwa einen prismatischen Aufbau aus isolierendem Formstoff.The plug adapters have a prismatic structure made of insulating material.

Die Zuleitungen können aus massiven Einzeladern bestehen, oder die Aderenden der Zuleitung können mit Leiterabschlusselementen (Endhülsen, Crimpkontakte) versehen sein. Am Schaltgerät befindet sich je Pol ein schraubenloser Klemmanschluss, in den die Zuleitung zur elektrischen Kontaktierung einschiebbar ist. Mit dem Einschieben erfolgt außerdem die alleinige mechanische Fixierung des Steckadapters am Gerät. Beim schraubenlosen Klemmanschluss handelt es sich um sogenannte Push-in-Kontaktklemmen. Die Anschlussklemmen des Klemmanschluss sind mittels Entriegelvorrichtung lösbar. Als Entriegelungsmittel ist ein Betätigungsbügel 42 vorhanden.The supply lines can consist of solid single wires, or the wire ends of the supply lines can be provided with conductor termination elements (end sleeves, crimp contacts). For each pole there is a screwless terminal connection on the switching device, into which the cable for electrical contacting can be inserted. When you push it in, the plug adapter is mechanically fixed to the device. The screwless terminal connection is a so-called push-in contact terminal. The terminals of the terminal connection can be released using the unlocking device. An actuating bracket 42 is provided as the unlocking means.

Typische für das elektrische Gerät und für die Steckadapter vorgesehene Leiterquerschnitte sind 1,0 bis 2,5 mm2.Typical conductor cross sections for the electrical device and for the plug adapters are 1.0 to 2.5 mm 2 .

Die Figur 1a zeigt ein elektrisches Gerät 100. Das Detail in Fig. 1b zeigt die am Gerät vorhandenen Anschlusskontakte 112 und Entkopplungsstößel 114. Drei Anschlusskontakte liegen nebeneinander an einer Zugangsseite 104 des Geräts, zum Beispiel in einer Reihe. Die Fig. 1a zeigt ein als elektrischer Schalter ausgebildetes Gerät, an dem an zwei Zugangsseiten je drei Reihen von Anschlusskontakte vorhanden sind. Die Zugangsöffnungen der Anschlusskontakte liegen parallel zur Zugangsseite.The Figure 1a shows an electrical device 100. The detail in Fig. 1b shows the connection contacts 112 and decoupling plungers 114 present on the device. Three connection contacts lie next to one another on an access side 104 of the device, for example in a row. The Fig. 1a shows a device designed as an electrical switch, on each of which there are three rows of connection contacts on two access sides. The access openings of the connection contacts are parallel to the access side.

In der Detailzeichnung Fig. 1b ist sichtbar, dass die Entkopplungsstößel 114 in einer Reihe oberhalb der Anschlusskontakte liegen und in ihrer Betätigungsrichtung um 90° gegen die Zugangsrichtung für die Zuleitungen orientiert sind. Die Klemmung in den schraubenlosen Anschlusskontakten wird mittels Betätigung der aus Entkoppelstößel gebildeten Zuleitungsentriegelvorrichtung gelöst. Die Entkopplungsstößel 114 ragen in der Länge ihres Betätigungshubs 106 aus dem Gehäuse des Geräts in Richtung auf die Oberseite des Geräts heraus.In the detail drawing Fig. 1b it can be seen that the decoupling plungers 114 lie in a row above the connection contacts and are oriented in their actuation direction by 90 ° against the direction of access for the feed lines. Clamping in the screwless connection contacts is released by actuating the cable release device formed from the decoupling plunger. The decoupling plungers 114 extend the length of their actuation stroke 106 from the housing of the device in the direction of the top of the device.

Die Fig. 2 zeigt perspektivisch einen einteiligen Steckadapter 20, bei dem die freien steckbaren Enden der Zuleitungen aus den Aufnahmekanälen mit einer zum Stecken hinreichenden Länge aus dem Steckadapter herausragen. In der gezeigten Situation ist der Steckadapter 20 mit den Zuleitungsadern 6 konfektioniert und vorbereitet zum Verbinden mit dem elektrischen Gerät.The Fig. 2 shows in perspective a one-piece plug adapter 20, in which the free protruding ends of the leads from the receiving channels with a sufficient length to plug out of the plug adapter. In the situation shown, the plug adapter 20 is assembled with the lead wires 6 and prepared for connection to the electrical device.

Der einteilige Steckadapter 20 für eine dreipolige Zuleitung 2 hat folgende Einzelheiten: er hat etwa prismatischen Aufbau aus isolierendem Formstoff. Seine Oberseite 21 (31) liegt in der gesteckten Situation parallel zur Oberseite 102 des elektrischen Geräts. Zugangsseite 104 und Oberseite 102 des Geräts haben eine Orientierung von 90° zueinander.The one-piece plug adapter 20 for a three-pole feed line 2 has the following details: it has an approximately prismatic structure made of insulating molding material. In the inserted situation, its top side 21 (31) lies parallel to the top side 102 of the electrical device. Access side 104 and top side 102 of the device have an orientation of 90 ° to one another.

Es ist je ein Aufhahmekanal 24 für je eine Zuleitungsader 6 vorhanden. Die Aufnahmekanäle liegen in einer Reihe nebeneinander und sind den Geräteanschlusskontakten 112 des Geräts zugeordnet.There is one receiving channel 24 for each supply line 6. The receiving channels lie in a row next to one another and are assigned to the device connection contacts 112 of the device.

Die Aufnahmekanäle 24 für Zuleitungsadern 6 liegen parallel im Steckadapter und haben eine Zugangsseite 22 zum Einführen der Zuleitungsadern 6 und eine Ausgangsseite 23 in Richtung auf die Geräteanschlusskontakte. Die Zuleitung, bzw. die Adern der Zuleitung werden so in die Aufnahmekanäle gelegt, dass die Enden der Zuleitungsadern genügend weit aus den Ausgangsseiten der Aufnahmekanäle herausstehen, so dass sie mit hinreichender Länge in den Geräteanschlusskontakten aufgenommen und geklemmt werden können.The receiving channels 24 for supply wires 6 are parallel in the plug adapter and have an access side 22 for inserting the supply wires 6 and an output side 23 in the direction of the device connection contacts. The supply line or the wires of the supply line are placed in the receiving channels in such a way that the ends of the supply lines protrude far enough from the output sides of the receiving channels so that they can be received and clamped with sufficient length in the device connection contacts.

Nicht dargestellt in den Figuren ist, dass die Ausgangsseiten der Aufnahmekanäle mit eingeengten Öffnungen ausgebildet sein können. Die Öffnungen sind hierbei gleich dem Durchmesser eines Leiterabschlusselements oder kleiner. Die Öffnungen sind elastisch vergrößerbar, so dass die eingeschobenen Leiteradern in den Öffnungen eingeklemmt werden.It is not shown in the figures that the outlet sides of the receiving channels can be designed with narrowed openings. The openings are equal to or smaller than the diameter of a conductor termination element. The openings can be enlarged elastically so that the inserted conductor wires are clamped in the openings.

Die Aufnahmekanäle 24 und/oder die Ausgangsöffnungen der Aufnahmekanäle sind vorzugsweise geometrisch so gestaltet, dass das Einlegen der Zuleitungsadern mit einem gewissen Kraftaufwand erfolgen muss, so dass die Zuleitung, bzw. die Zuleitungsadern in dem Steckadapter klemmend aufgenommen sind.The receiving channels 24 and / or the outlet openings of the receiving channels are preferably geometrically designed so that the insertion of the supply wires must be done with a certain amount of force, so that the supply line or the supply wires are received in a clamping manner in the plug adapter.

An dem einteilig Steckadapter 20 ist ein federnd angeordneter Betätigungsbügel 42 vorhanden, welcher in der Stellung der Steckverbindung (also im gesteckten Zustand) zwischen Steckadapter und Gerät der Entriegelvorrichtung 114 am Gerät zugeordnet ist. Diese Einzelheit ist in der Fig. 6 im Detail gezeigt. Der Betätigungsbügel 42 sitzt an der Oberseite 21 des Steckadapters am Ende des Formkörpers, an dem er den Anschlusskontakten am Gerät in der gesteckten Situation zugewandt ist. Der Betätigungsbügel 42 ist über ein Filmscharnier 40 beweglich am Steckadapter angebunden.On the one-piece plug adapter 20 there is a resiliently arranged actuating bracket 42, which is assigned to the unlocking device 114 on the device in the position of the plug connection (that is, in the inserted state) between the plug adapter and the device. This detail is in the Fig. 6 shown in detail. The operating bracket 42 sits on the Top 21 of the plug adapter at the end of the molded body, on which it faces the connection contacts on the device in the inserted situation. The actuating bracket 42 is movably connected to the plug-in adapter via a film hinge 40.

Die Entkopplungsstößel 114 der in den Anschlusskontakten ausgebildeten Klemmvorrichtung werden über den Betätigungsbügel 42 beaufschlagt, wobei die manuelle Betätigung des Betätigungsbügels 42 die Entkopplungsstößel 114 gemeinsam berührt und niederdrückt. Damit werden die in die Anschlusskontakte eingeführten Zuleitungsadern freigegeben.The decoupling plungers 114 of the clamping device formed in the connection contacts are acted upon via the actuating bracket 42, the manual actuation of the actuating bracket 42 touching and depressing the decoupling plunger 114 together. The lead wires inserted into the connection contacts are thus released.

Die Fig. 3 zeigt einen zweiteiligen Steckadapter 30 mit Blick auf die Ausgangsseite 22 für dreipolige Zuleitungen ohne eingelegte Zuleitungen. Die Zuleitung werden in das Adapteroberteil gelegt, dann werden die positionierten Leitungsadern in dem Adapteroberteil zusammen mit dem Adapterunterteil hineingeschoben und verrastet.The Fig. 3 shows a two-part plug adapter 30 with a view of the output side 22 for three-pole leads without inserted leads. The supply lines are placed in the upper part of the adapter, then the positioned wires are pushed into the upper part of the adapter together with the lower part of the adapter and locked.

In der Fig. 4 ist der zweiteilige Steckadapter 30 mit Blick auf die Zugangsseite 23 mit eingelegten Zuleitungsadern 6 dargestellt.In the Fig. 4 the two-part plug adapter 30 is shown with a view of the access side 23 with inserted supply wires 6.

In der Fig. 5 ist perspektivisch in Explosionszeichnung ein Adapteroberteil 32 und ein Adapterunterteil 33 eines zweiteiligen Steckadapters zu erkennen. Wie bei dem einteiligen Steckadapter 20 befindet sich ein federnd angeordneter Betätigungsbügel 42 an der Oberseite 31 des zweiteiligen Steckadapters 30.In the Fig. 5 is an exploded perspective view of an adapter upper part 32 and an adapter lower part 33 of a two-part plug-in adapter. As with the one-piece plug adapter 20, there is a resilient actuating bracket 42 on the top 31 of the two-piece plug adapter 30.

In den Figuren 4 und 5 sind besonders herausgehoben, dass zur Klemmung der Zuleitungsadern elastisch bewegliche Klemmbacken 44 vorhanden sind. Die Klemmbacken 44 sind über Filmscharniere 46 im Adapteroberteil 32 angeordnet. Zur weiteren Fixierung eingeschobener Zuleitungsadern sind außerdem Klemmrippen 48 (beidseitig) auf den Innenseiten der Klemmbacken 44 vorgesehen. Die Klemmrippen verlaufen parallel zur Ausrichtung der den Aufnahmekanal definierenden Klemmbacken 44. Am Adapteroberteil 32 ist eine Haltekante 34 vorhanden, die den beiden Teilen bei der Verrastung Halt gibt. Im Adapterunterteil 33 sind U-förmige Aufnahmeschalen 50 ausgebildet, die beim Zusammenbau von Adapteroberteil 32 und Adapterunterteil 33 insbesondere die Klemmbacken 44 im unteren Bereich der Aufnahmeschalen zueinander hin bewegen und die letztendliche Klemmung bewirken.In the Figures 4 and 5 are particularly emphasized that there are elastically movable clamping jaws 44 for clamping the supply wires. The clamping jaws 44 are arranged in the upper adapter part 32 via film hinges 46. Clamping ribs 48 (on both sides) are also provided on the inside of the clamping jaws 44 for further fixing of inserted supply wires. The clamping ribs run parallel to the alignment of the clamping jaws 44 defining the receiving channel. A holding edge 34 is provided on the adapter upper part 32, which gives the two parts a stop when they are latched. U-shaped receiving shells 50 are formed in the adapter lower part 33, which move the clamping jaws 44 in the lower region of the receiving shells towards one another when the adapter upper part 32 and adapter lower part 33 are assembled, and bring about the final clamping.

Die Fig. 6 liefert eine Seitenansicht eines gesteckten, einteiligen Steckadapters. Ein Steckadapter 20, 30 befindet sich in Verbindung über die Zuleitungsadern mit dem elektrischen Gerät. Der Betätigungsbügel 42 reicht mit vergleichbarer Länge wie die Enden der Zuleitungsadern in Richtung auf die Zugangsseite des Geräts und liegt somit oberhalb der Entkopplungsstößel 114.The Fig. 6 provides a side view of a plugged, one-piece plug adapter. On Plug adapter 20, 30 is connected to the electrical device via the lead wires. The actuating bracket 42 extends with a length comparable to the ends of the supply wires in the direction of the access side of the device and is thus located above the decoupling plunger 114.

In der Fig. 7 ist ein Leiterabschluss einer Zuleitung gezeigt, die als Doppelader ausgeführt ist. In einem für derartige Leiterabschlüsse ausgebildeten Steckadapter ist jeder Aufnahmekanal 24 zur Aufnahme eines Zuleitungsadern 6, 8 verpressenden Crimpkontakts 12 ausgebildet.In the Fig. 7 a conductor termination of a supply line is shown, which is designed as a double wire. In a plug-in adapter designed for such conductor terminations, each receiving channel 24 is designed to receive a crimp contact 12 that compresses supply leads 6, 8.

Ein solcher als besondere Variante ausgeführter Leiterabschluss besteht gemäß Fig. 7 in einem Crimpkontakt 12, bei dem die Leiterenden 6, 8 der Doppelader mittels der Pressklammer 16 elektrisch eingebunden sind. Die Pressklammer (crimp) 18 für die Adernisolierung (Leitermantel) hat entsprechend längere Schenkel als die Leiter-Pressklammer 16. In der dargestellten Form kann eine elektrische Doppelader beispielsweise mit je 2 mm2 oder 2,5 mm2 Leiterquerschnitt in einen Aufnahmekanal eines Steckadapters eingelegt werden. Mit einer solchen Maßnahme lassen sich zwei dreipolige Zuleitungen in "gedoppelter" Form konfektionieren und zur Herstellung der Verbindung mit einem elektrischen Gerät vorbereiten.Such a ladder termination, which is designed as a special variant, exists according to Fig. 7 in a crimp contact 12 in which the conductor ends 6, 8 of the double wire are electrically connected by means of the press clamp 16. The crimp 18 for the wire insulation (conductor sheath) has correspondingly longer legs than the conductor crimp 16. In the form shown, an electrical double core, for example with a cross section of 2 mm 2 or 2.5 mm 2, can be inserted into a receiving channel of a plug-in adapter become. With such a measure, two three-pole leads can be assembled in a "double" form and prepared for the connection with an electrical device.

Der freie Leiterstift (Kontaktzunge 13) des Crimpkontakts ragt aus dem Steckadapter heraus und ist in die Anschlusskontakte des elektrischen Geräts unmittelbar steckbar. Die Kontaktzungen des Crimpkontakts verrasten in den Anschlusskontakten. Die Ausbildung der beiden Pressklammern 16 und 18 an der Kontaktzunge 13 ist eine Besonderheit des dargestellten Crimpkontakts 12 - als extra ausgelegter Teilbereich des Crimpkontakts. Mit Hilfe der am Crimpkontakt ausgebildeten Rastzunge 14 kommt es im (einteiligen) Steckadapter zu einer Fixierung des Crimpkontakts. Drei dieser in Fig. 7 dargestellten Crimpkontakte können in einem dreipoligen Steckadapter eingebracht, und so in die Anschlusskontakte gesteckt und verrastet werden.The free conductor pin (contact tongue 13) of the crimp contact protrudes from the plug adapter and can be inserted directly into the connection contacts of the electrical device. The contact tongues of the crimp contact snap into the connection contacts. The formation of the two press clips 16 and 18 on the contact tongue 13 is a special feature of the crimp contact 12 shown - as a specially designed partial area of the crimp contact. With the aid of the latching tongue 14 formed on the crimp contact, the crimp contact is fixed in the (one-piece) plug adapter. Three of these in Fig. 7 The crimp contacts shown can be inserted into a three-pin plug adapter, and thus inserted and locked in the connection contacts.

Der in der Figur 7 dargestellte Leiterabschluss einer Doppelader lässt sich auch mit einem Crimpkontakt für nur eine einzelne Zuleitungsader verwenden. Hierbei würde beispielsweise eine Zuleitungsader mit bis zu 2,5 mm2 Leiterquerschnitt verwendbar sein. Hierbei wird anstatt der beschriebenen ,gedoppelten' Form der Zuleitung ein feindrähtiger Leiter mit entsprechendem Leiterquerschnitt eingesetzt.The Indian Figure 7 The illustrated conductor termination of a double wire can also be used with a crimp contact for only a single supply wire. In this case, for example, a supply wire with a conductor cross section of up to 2.5 mm 2 would be usable. Here, instead of the described, double 'form of the supply line, a fine-stranded conductor with a corresponding conductor cross-section is used.
