Definitions

  • the invention relates to a clamp for electrical lines according to the preamble of claim 1.
  • Such a terminal comprises a housing that forms a bearing area on which a separating element is movably mounted between a contact position in which the separating element electrically connects two contacts to one another and a separated position in which the separating element electrically separates the two contacts from one another.
  • Such a clamp in the form of a disconnect clamp with a plurality of parallel disconnect elements, is described in DE 20 2016 103 277 U1.
  • the separating elements are usually mounted on the housing via a pin of the respective separating element, which is received in a hole in a housing part of the terminal.
  • This hole acts not only to attach the divider, but also as a pivot point.
  • the separating blade can be swiveled into a shaft via the pivot point, for example, in order to close an electrical circuit.
  • the hole and the shaft for the separating element are usually orthogonal to one another as a result. If the housing is to be produced by plastic injection molding, this means that a slide is required in the injection molding tool for demolding the housing, which forms either the hole or the shaft, which also leads to at least one additional lateral opening. This can represent an optical impairment and dirt can also penetrate here. Furthermore, the insulation can be impaired by the opening, because this usually shortens the distance to conductive components.
  • slides in injection molds are not only technically complex, but also expensive. Furthermore, the use of slides is not possible with all housing shapes, so that the use of one or more such slides regularly restricts the freedom of design, which makes production even more difficult.
  • the object of the present invention is to provide a clamp for electrical lines that is particularly easy to produce.
  • the bearing point for the separating element (e.g. on the housing) and still manufacture the components (e.g. housing parts) without using a slide in the injection molding process.
  • the bearing point can form part of a snap-in connection, in particular serving as a snap-in receptacle.
  • a component, e.g. the separating element, can be latched to the bearing point. This can significantly simplify the manufacture of the clamp.
  • the clamp forms a bearing point on both sides of the separating element.
  • both sections of the storage area describe an arc of a circle in cross section, in particular a semicircle or smaller.
  • the separating element can thus be stored in a simple manner and directly on the two components, and only a few parts are required.
  • the two sections of the storage area form, for example, a circular-cylindrical receptacle.
  • one or both of the sections of the storage area is trough-shaped.
  • the separating element can be pivoted about a pivot axis on the storage area. This enables a particularly simple adjustment between the contact position and the disconnected position.
  • the separating element comprises a pin that is accommodated in the bearing area, in particular a pin in each case that is in one of the two bearing areas formed on either side of the separating element.
  • the housing forms a receptacle within which the separating element can be moved.
  • the receptacle is designed, for example, in the form of a shaft.
  • the receptacle (the shaft) in the housing extends perpendicularly to the pivot axis.
  • At least one of the components eg a first housing part, has at least one outer wall which is closed at a point towards which the pivot axis points. Since no slide is required for the production of this housing part by means of an injection molding tool, the outer wall of the housing can be closed off from the same material on the straight extension of the pivot axis. This enables insulation protection and, for example, preventing the ingress of dirt or liquids on the separating element and thus the To protect the area of the particularly sensitive separation point between the contacts that can be electrically connected to one another by means of the separating element.
  • the first housing part is designed in the form of a (particularly outer) upper shell. It can be provided that the second component (e.g. in the form of a second housing part) can be inserted into the upper shell. As a result, a largely uniform outer surface is possible, as well as particularly simple assembly.
  • first housing part and a further housing part can be positively latched to one another by means of one or more latching hooks.
  • the latching hook or latches are formed, for example, on the second housing part and engage, for example, in an opening in the first housing part in a latching manner.
  • the separating element comprises a contact blade, for example, which can be inserted into at least one slot of a connecting conductor, which is electrically connected to one of the contacts, for example in an electrically contacting manner. This enables an electrical connection that is easy to produce and can be separated again and at the same time is secure.
  • the separating element optionally comprises an engagement area to which a tool can be attached in order to move the separating element between the contact position and the separating position by means of the tool.
  • the separating element can be made particularly small.
  • the two components are made of plastic, for example, in particular in the form of injection-moulded plastic parts. While the configuration of the storage area described above can achieve a simplification in many conceivable manufacturing processes, it is particularly effective in the case of injection-molded parts.
  • the housing also forms a number of connections for the electrical connection of one electrical line each. Provision can be made for at least one of the connections to be in the form of a push-in connection, for example, although other types of connections are also conceivable. This enables the terminal to be connected particularly easily and quickly. In addition, it is possible to design and arrange such push-in connections in a particularly space-saving manner.
  • the clamp can be designed in the form of a disconnect clamp, which comprises, for example, a collective connection which can be electrically connected to a plurality of connections arranged in a row via one of a plurality of disconnect elements.
  • the clamp includes an insert disposed between the first and second housing parts and having one or more partitions.

  • the collective terminal A and each of the terminals A1-A6 are provided on the common housing G.
  • the collective connection A and each of the connections A1-A6 each form a receptacle into which an electrical conductor L1, L2 can be inserted in order to make electrical contact with a contact area inside the terminal 1.
  • An electrical conductor L2 connected to each of the connections A1-A6 can be electrically connected to an electrical conductor L1 connected to the common connection A.
  • the terminal 1 comprises a separating element 13 for each of the connections A1-A6.

  • connection conductor 14 which is referred to below as the bus connection conductor 14 for simplified reference.
  • connections A1-A6 is electrically connected to a contact K1-K6 via a connection conductor 14A-14E.
  • the separating elements 13 are each between the contact position in which the respective separating element 13 electrically connects two contacts K, K1-K6 (namely a contact K of the common connection conductor 14 and one of the contacts K1-K6, which is assigned to the respective separating element 13), and the separating position, in which the separating element 13 electrically separates the two contacts K, K1-K6 from one another.
  • the separating elements 13 are each shown in simplified form in the form of a switch; it should be pointed out that it is also possible for the separating elements 13 in the respective separating position not to make electrical contact with any of the two contacts K, K1-K6 that can be electrically connected thereto.

Description

Klemme für elektrische Leitungen Clamp for electrical lines
Die Erfindung betrifft eine Klemme für elektrische Leitungen nach dem Oberbegriff des Anspruchs 1. The invention relates to a clamp for electrical lines according to the preamble of claim 1.
Eine derartige Klemme umfasst ein Gehäuse, das einen Lagerbereich ausbildet, an dem ein Trennelement zwischen einer Kontaktstellung, in der das Trennelement zwei Kontakte elektrisch miteinander verbindet, und einer Trennstellung, in der das Trennelement die beiden Kontakte elektrisch voneinander trennt, bewegbar gelagert ist. Such a terminal comprises a housing that forms a bearing area on which a separating element is movably mounted between a contact position in which the separating element electrically connects two contacts to one another and a separated position in which the separating element electrically separates the two contacts from one another.
Eine solche Klemme, in der Form einer Trennklemme mit mehreren parallelen Trennelementen, ist in der DE 20 2016 103 277 U1 beschrieben. Such a clamp, in the form of a disconnect clamp with a plurality of parallel disconnect elements, is described in DE 20 2016 103 277 U1.
Bei derartigen Klemmen werden die Trennelemente in der Regel über einen Pin des jeweiligen Trennelements, der in einem Loch in einem Gehäuseteil der Klemme aufgenommen wird, am Gehäuse montiert. Dieses Loch fungiert nicht nur zur Befestigung des T rennelements, sondern auch als Drehpunkt. Über den Drehpunkt kann das Trennmesser z.B. in einen Schacht geschwenkt werden, um einen elektrischen Stromkreis zu schließen. Das Loch und der Schacht für das Trennelement liegen hierdurch allerdings für gewöhnlich orthogonal zueinander. Soll das Gehäuse im Kunststoffspritzguss hergestellt werden, dann bedeutet dies allerdings für die Entformung des Gehäuses, dass ein Schieber im Spritzgusswerkzeug benötigt wird, der entweder das Loch oder den Schacht ausformt, was auch zu zumindest einer zusätzlichen seitlichen Öffnung führt. Das kann eine optische Beeinträchtigung darstellen und zudem kann hierüber Schmutz eindringen. Ferner kann durch die Öffnung die Isolation beeinträchtigt werden, weil dadurch der Abstand zu leitenden Bauteilen in der Regel gekürzt wird. In the case of such terminals, the separating elements are usually mounted on the housing via a pin of the respective separating element, which is received in a hole in a housing part of the terminal. This hole acts not only to attach the divider, but also as a pivot point. The separating blade can be swiveled into a shaft via the pivot point, for example, in order to close an electrical circuit. However, the hole and the shaft for the separating element are usually orthogonal to one another as a result. If the housing is to be produced by plastic injection molding, this means that a slide is required in the injection molding tool for demolding the housing, which forms either the hole or the shaft, which also leads to at least one additional lateral opening. This can represent an optical impairment and dirt can also penetrate here. Furthermore, the insulation can be impaired by the opening, because this usually shortens the distance to conductive components.
Schieber in Spritzgusswerkzeugen sind ferner nicht nur technisch aufwändig, sondern auch kostenintensiv. Des Weiteren ist der Einsatz von Schiebern nicht bei allen Gehäuseformen möglich, sodass durch den Einsatz von einem oder mehreren solcher Schieber die Gestaltungsfreiheit regelmäßig eingeschränkt wird, was die Herstellung weiter erschwert. In addition, slides in injection molds are not only technically complex, but also expensive. Furthermore, the use of slides is not possible with all housing shapes, so that the use of one or more such slides regularly restricts the freedom of design, which makes production even more difficult.
Aufgabe der vorliegenden Erfindung ist es, eine Klemme für elektrische Leitungen zur Verfügung zu stellen, die besonders einfach herstellbar ist. The object of the present invention is to provide a clamp for electrical lines that is particularly easy to produce.
Diese Aufgabe wird durch einen Gegenstand mit den Merkmalen des Anspruchs 1 gelöst. Demnach ist vorgesehen, dass zwei Bauteile der Klemme jeweils mindestens einen Abschnitt des Lagerbereichs ausbilden. This object is solved by an object with the features of claim 1. Accordingly, it is provided that two components of the clamp each form at least one section of the bearing area.
Dies ermöglicht es, die Lagerstelle für das Trennelement (z.B. am Gehäuse) bereitzustellen und dennoch die Bauteile (z.B. Gehäuseteile) ohne Einsatz eines Schiebers im Spritzgussverfahren herzustellen. Überdies kann die Lagerstelle einen Teil einer Rastverbindung ausbilden, insbesondere als Rastaufnahme dienen. Ein Bauteil, z.B. das Trennelement, kann mit der Lagerstelle verrastbar sein. Hierdurch kann die Herstellung der Klemme deutlich vereinfacht werden. Optional bildet die Klemme beiderseits des Trennelements eine Lagerstelle aus. This makes it possible to provide the bearing point for the separating element (e.g. on the housing) and still manufacture the components (e.g. housing parts) without using a slide in the injection molding process. In addition, the bearing point can form part of a snap-in connection, in particular serving as a snap-in receptacle. A component, e.g. the separating element, can be latched to the bearing point. This can significantly simplify the manufacture of the clamp. Optionally, the clamp forms a bearing point on both sides of the separating element.
Optional beschreiben beide Abschnitte des Lagerbereichs im Querschnitt einen Kreisbogen, insbesondere jeweils einen Halbkreis oder kleiner. So kann das Trennelement in einfacher Weise und direkt an den beiden Bauteilen gelagert werden und es werden nur wenige Teile benötigt. Gemeinsam bilden die beiden Abschnitte des Lagerbereichs z.B. eine kreiszylindrische Aufnahme. Beispielsweise ist einer der Abschnitte oder sind beide Abschnitte des Lagerbereichs wannenförmig. Optionally, both sections of the storage area describe an arc of a circle in cross section, in particular a semicircle or smaller. The separating element can thus be stored in a simple manner and directly on the two components, and only a few parts are required. Together, the two sections of the storage area form, for example, a circular-cylindrical receptacle. For example, one or both of the sections of the storage area is trough-shaped.
Insbesondere kann das Trennelement am Lagerbereich um eine Schwenkachse schwenkbar gelagert sein. Das ermöglicht eine besonders einfache Verstellung zwischen der Kontaktstellung und der Trennstellung. Beispielsweise umfasst das Trennelement einen Stift, der im Lagerbereich aufgenommen ist, insbesondere jeweils einen Stift, der in jeweils einer der beiderseits des Trennelements ausgebildeten zwei Lagerbereiche. In particular, the separating element can be pivoted about a pivot axis on the storage area. This enables a particularly simple adjustment between the contact position and the disconnected position. For example, the separating element comprises a pin that is accommodated in the bearing area, in particular a pin in each case that is in one of the two bearing areas formed on either side of the separating element.
Das Gehäuse bildet in einer Ausgestaltung eine Aufnahme aus, innerhalb der das Trennelement bewegbar ist. Das ermöglicht es, dass das Trennelement zumindest in einer seiner Stellungen nicht oder nur zum Teil aus dem Gehäuse vorsteht, wodurch eine versehentliche Bewegung des Trennelements relativ zum Gehäuse verhindert werden kann. Die Aufnahme ist z.B. in Form eines Schachts ausgebildet. Beispielsweise erstreckt sich die Aufnahme (der Schacht) im Gehäuse senkrecht zur Schwenkachse. In one configuration, the housing forms a receptacle within which the separating element can be moved. This makes it possible for the separating element not to protrude or only partially protrude from the housing in at least one of its positions, as a result of which an accidental movement of the separating element relative to the housing can be prevented. The receptacle is designed, for example, in the form of a shaft. For example, the receptacle (the shaft) in the housing extends perpendicularly to the pivot axis.
Zumindest eines der Bauteile, z.B. ein erstes Gehäuseteil, weist zumindest eine Außenwand auf, die an einer Stelle, auf welche die Schwenkachse zeigt, geschlossen ist. Da kein Schieber für die Herstellung dieses Gehäuseteils mittels eines Spritzgusswerkzeugs notwendig ist, kann die Außenwand des Gehäuses an der geradlinigen Verlängerung der Schwenkachse materialeinheitlich verschlossen sein. Das ermöglicht einen Isolationsschutz und z.B. das Eindringen von Schmutz oder Flüssigkeiten am Trennelement zu verhindern und damit den Bereich der besonders sensiblen Trennstelle zwischen den mittels des Trennelements elektrisch miteinander verbindbaren Kontakten zu schützen. At least one of the components, eg a first housing part, has at least one outer wall which is closed at a point towards which the pivot axis points. Since no slide is required for the production of this housing part by means of an injection molding tool, the outer wall of the housing can be closed off from the same material on the straight extension of the pivot axis. This enables insulation protection and, for example, preventing the ingress of dirt or liquids on the separating element and thus the To protect the area of the particularly sensitive separation point between the contacts that can be electrically connected to one another by means of the separating element.
Beispielsweise ist das erste Gehäuseteil in Form einer (insbesondere äußeren) Oberschale ausgebildet. Dabei kann vorgesehen sein, dass in die Oberschale das zweite Bauteil (z.B. in Form eines zweiten Gehäuseteils) eingesetzt werden kann. Hierdurch ist eine weitgehend einheitliche Außenoberfläche möglich, sowie eine besonders einfache Montage. For example, the first housing part is designed in the form of a (particularly outer) upper shell. It can be provided that the second component (e.g. in the form of a second housing part) can be inserted into the upper shell. As a result, a largely uniform outer surface is possible, as well as particularly simple assembly.
In einer Weiterbildung sind das erste Gehäuseteil und ein weiteres Gehäuseteil (z.B. ein drittes Gehäuseteil) mittels einem oder mehrerer Rasthaken formschlüssig miteinander verrastbar. Das ermöglicht eine schnelle und einfache Montage. Der oder die Rasthaken sind beispielsweise am zweiten Gehäuseteil ausgebildet und greifen z.B. jeweils in eine Öffnung im ersten Gehäuseteil verrastend ein. In a further development, the first housing part and a further housing part (e.g. a third housing part) can be positively latched to one another by means of one or more latching hooks. This enables quick and easy assembly. The latching hook or latches are formed, for example, on the second housing part and engage, for example, in an opening in the first housing part in a latching manner.
Das Trennelement umfasst z.B. ein Kontaktmesser, das beispielsweise elektrisch kontaktierend in zumindest einen Schlitz eines Anschlussleiters einführbar ist, der mit einem der Kontakte elektrisch verbunden ist. Dies ermöglicht eine leicht herstellbare und wieder trennbare, und zugleich sichere elektrische Verbindung. The separating element comprises a contact blade, for example, which can be inserted into at least one slot of a connecting conductor, which is electrically connected to one of the contacts, for example in an electrically contacting manner. This enables an electrical connection that is easy to produce and can be separated again and at the same time is secure.
Das Trennelement umfasst optional einen Eingriffsbereich, an den ein Werkzeug angesetzt werden kann, um das Trennelement mittels des Werkzeugs zwischen der Kontaktstellung und der Trennstellung zu bewegen. Hierdurch kann das Trennelement besonders klein aufgebaut werden. The separating element optionally comprises an engagement area to which a tool can be attached in order to move the separating element between the contact position and the separating position by means of the tool. As a result, the separating element can be made particularly small.
Die beiden Bauteile sind z.B. aus Kunststoff hergestellt, insbesondere in Form von Kunststoff- Spritzgussteilen. Während die oben beschriebene Ausgestaltung des Lagerbereichs bei vielen denkbaren Herstellungsverfahren eine Vereinfachung erzielen kann, kommt sie bei Spritzgussteilen besonders zum tragen. The two components are made of plastic, for example, in particular in the form of injection-moulded plastic parts. While the configuration of the storage area described above can achieve a simplification in many conceivable manufacturing processes, it is particularly effective in the case of injection-molded parts.
Das Gehäuse bildet ferner mehrere Anschlüsse zum elektrischen Anschließen von jeweils einer elektrischen Leitung aus. Dabei kann vorgesehen sein, dass zumindest einer der Anschlüsse z.B. in Form eines Push-In-Anschlusses ausgebildet ist, wobei auch andere Arten von Anschlüssen denkbar sind. Das ermöglicht einen besonders einfachen und schnellen Anschluss der Klemme. Darüber hinaus ist es möglich, derartige Push-In-Anschlüsse besonders platzsparend auszubilden und anzuordnen. Die Klemme kann in Form einer Trennklemme ausgebildet sein, die z.B. einen Sammelanschluss umfasst, der mit mehreren, in einer Reihe angeordneten Anschlüssen elektrisch über jeweils eines von mehreren Trennelementen verbindbar ist. Optional umfasst die Klemme einen Einsatz, der zwischen dem ersten und dem zweiten Gehäuseteil angeordnet ist und der eine oder mehrere Trennwände aufweist. The housing also forms a number of connections for the electrical connection of one electrical line each. Provision can be made for at least one of the connections to be in the form of a push-in connection, for example, although other types of connections are also conceivable. This enables the terminal to be connected particularly easily and quickly. In addition, it is possible to design and arrange such push-in connections in a particularly space-saving manner. The clamp can be designed in the form of a disconnect clamp, which comprises, for example, a collective connection which can be electrically connected to a plurality of connections arranged in a row via one of a plurality of disconnect elements. Optionally, the clamp includes an insert disposed between the first and second housing parts and having one or more partitions.

Fig. 9 ein Schaltbild der Klemme gemäß Fig. 1. Fig. 1 zeigt eine Klemme 1 zum Anschluss von elektrischen Leitungen L1 , L2. Die Klemme 1 ist vorliegend in Form einer Trennklemme aufgebaut und umfasst ein Gehäuse G mit, neben einem hier zur vereinfachten Bezugnahme als Sammelanschluss A bezeichneten Anschluss, mehreren, beispielhaft sechs (alternativ z.B. zwei, vier, acht, zehn oder zwölf) Anschlüssen A1-A6 für jeweils einen elektrischen Leiter L2. Der Sammelanschluss A und jeder der Anschlüsse A1-A6 sind am gemeinsamen Gehäuse G vorgesehen. Der Sammelanschluss A und jeder der Anschlüsse A1-A6 bilden jeweils eine Aufnahme aus, in die ein elektrischer Leiter L1 , L2 eingeschoben werden kann, um im Inneren der Klemme 1 einen Kontaktbereich elektrisch zu kontaktieren. Über jeden der der Anschlüsse A1-A6 kann ein jeweils daran angeschlossener elektrischer Leiter L2 elektrisch mit einem am Sammelanschluss A angeschlossenen elektrischen Leiter L1 verbunden werden. Fig. 9 shows a circuit diagram of the terminal according to Fig. 1. 1 shows a terminal 1 for connecting electrical lines L1, L2. The terminal 1 is presently constructed in the form of a disconnect terminal and comprises a housing G with, in addition to a connection referred to here as a collective connection A for simplified reference, several, for example six (alternatively eg two, four, eight, ten or twelve) connections A1-A6 for each one electrical conductor L2. The collective terminal A and each of the terminals A1-A6 are provided on the common housing G. The collective connection A and each of the connections A1-A6 each form a receptacle into which an electrical conductor L1, L2 can be inserted in order to make electrical contact with a contact area inside the terminal 1. An electrical conductor L2 connected to each of the connections A1-A6 can be electrically connected to an electrical conductor L1 connected to the common connection A.
Ferner umfasst die Klemme 1 für jeden der Anschlüsse A1-A6 ein Trennelement 13. Jedes der Trennelemente 13 ist bewegbar, im gezeigten Beispiel schwenkbar, an der Klemme 1 gelagert, und zwar konkret zwischen einer Trennstellung und einer Kontaktstellung. Fig. 1 zeigt die Trennelemente 13 jeweils in der Kontaktstellung, in der das Trennelement 13 den jeweiligen Anschluss A1-A6 elektrisch mit dem Sammelanschluss A verbindet. Fig. 2 zeigt die Trennelemente 13 jeweils in der Trennstellung, in der die jeweiligen Anschlüsse A1-A6 elektrisch vom Sammelanschluss A getrennt sind. Indem ein Trennelement 13 in die Trennstellung bewegt wird, kann somit ein Stromkreis geöffnet werden. Umgekehrt kann ein Stromkreis geschlossen werden, indem ein Trennelement 13 in die Kontaktstellung bewegt wird. Furthermore, the terminal 1 comprises a separating element 13 for each of the connections A1-A6. Each of the separating elements 13 is movable, pivotable in the example shown, mounted on the terminal 1, specifically between a disconnected position and a contact position. 1 shows the separating elements 13 in the contact position in which the separating element 13 electrically connects the respective connection A1-A6 to the common connection A. 2 shows the isolating elements 13 in the disconnected position in which the respective connections A1-A6 are electrically disconnected from the common connection A. A circuit can thus be opened by moving a disconnecting element 13 into the disconnected position. Conversely, a circuit can be closed by moving a separating element 13 into the contact position.
Fig. 9 zeigt diesen Aufbau in Form eines Schaltbildes. Der Sammelanschluss A ist über einen Anschlussleiter, der zur vereinfachten Bezugnahme im Folgenden als Sammelanschlussleiter 14 bezeichnet wird, mit mehreren, vorliegend sechs, Kontakten K elektrisch verbunden. Jeder der mehreren, vorliegend sechs, Anschlüsse A1-A6 ist über jeweils einen Anschlussleiter 14A- 14E mit einem Kontakt K1-K6 elektrisch verbunden. Die Trennelemente 13 sind jeweils zwischen der Kontaktstellung, in der das jeweilige Trennelement 13 zwei Kontakte K, K1-K6 (nämlich einen Kontakt K des Sammelanschlussleiters 14 und einen der Kontakte K1-K6, der dem jeweiligen Trennelement 13 zugeordnet ist) elektrisch miteinander verbindet, und der Trennstellung, in der das Trennelement 13 die beiden Kontakte K, K1-K6 elektrisch voneinander trennt, bewegbar gelagert. In Fig. 9 sind die Trennelemente 13 jeweils vereinfacht in Form eines Schalters dargestellt; es sei darauf hingewiesen, dass es auch möglich ist, dass die Trennelemente 13 in der jeweiligen Trennstellung keinen der beiden damit elektrisch verbindbaren Kontakte K, K1-K6 elektrisch kontaktiert. Zwischen dem Sammelanschlussleiter 14 und jedem der Anschlussleiter 14A-14F ist somit eine T rennstelle X1 -X6 vorgesehen, welche mittels des jeweiligen T rennelements 13 elektrisch geschlossen werden kann. 9 shows this structure in the form of a circuit diagram. The bus connection A is electrically connected to a plurality of contacts K, in this case six, via a connection conductor, which is referred to below as the bus connection conductor 14 for simplified reference. Each of the several, in this case six, connections A1-A6 is electrically connected to a contact K1-K6 via a connection conductor 14A-14E. The separating elements 13 are each between the contact position in which the respective separating element 13 electrically connects two contacts K, K1-K6 (namely a contact K of the common connection conductor 14 and one of the contacts K1-K6, which is assigned to the respective separating element 13), and the separating position, in which the separating element 13 electrically separates the two contacts K, K1-K6 from one another. In FIG. 9, the separating elements 13 are each shown in simplified form in the form of a switch; it should be pointed out that it is also possible for the separating elements 13 in the respective separating position not to make electrical contact with any of the two contacts K, K1-K6 that can be electrically connected thereto. A separation point X1 -X6 is thus provided between the collective connection conductor 14 and each of the connection conductors 14A-14F, which can be electrically closed by means of the respective isolating element 13 .
Um die Trennelemente 13 zwischen der Trennstellung und der Kontaktstellung zu bewegen, umfasst jedes Trennelement 13 einen Eingriffsbereich 133 zum Eingriff durch ein Werkzeug W. Vorliegend ist der Eingriffsbereich 133 jeweils vorzugsweise in Form eines Schlitzes ausgebildet, in welchen mit dem als Schlitzschraubendreher ausgebildeten Werkzeug W eingegriffen werden kann, wobei auch ein manuell betätigbarer Bereich am Trennelement 13 denkbar ist (z.B. wenn die Klemme 1 als Messertrennklemme ausgebildet ist). In order to move the separating elements 13 between the separating position and the contact position, each separating element 13 comprises an engagement area 133 for engagement by a tool W. In the present case, the engagement area 133 is preferably in the form of a slot in which the tool W, which is designed as a slotted screwdriver, can be engaged a manually operable area on the separating element 13 is also conceivable (e.g. if the clamp 1 is designed as a knife disconnect clamp).
Die Trennelemente 13 sind am Gehäuse G bewegbar gelagert, und zwar vorliegend derart, dass jedes der Trennelemente 13 in einer jeweiligen Aufnahme R im Gehäuse G verlagert werden kann. Die Aufnahmen R sind jeweils in Form eines Schachts ausgebildet. The separating elements 13 are movably mounted on the housing G, in the present case such that each of the separating elements 13 can be displaced in a respective receptacle R in the housing G. The recordings R are each in the form of a shaft.
Anhand Fig. 1 und 2 ist ferner zu erkennen, dass jedes der Trennelemente 13 einen Schwenkkörper 131 aufweist, an dem der Eingriffsbereich 133 ausgebildet ist und an dem ein Kontaktmesser 130 befestigt ist. Das Kontaktmesser 130 ist aus elektrisch leitfähigem Material hergestellt. Die Trennelemente 13 können auch als Trennmesser bezeichnet werden. It can also be seen from FIGS. 1 and 2 that each of the separating elements 13 has a pivoting body 131 on which the engagement area 133 is formed and on which a contact blade 130 is attached. The contact blade 130 is made of electrically conductive material. The separating elements 13 can also be referred to as separating knives.
Der Sammelanschluss A weist einen größeren Querschnitt auf im Vergleich zu den einzelnen Anschlüssen A1-A6. Sowohl der Sammelanschluss A als auch die Anschlüsse A1-A6 sind in Form von Push-In-Anschlüssen ausgebildet. Die elektrischen Leitungen L1 , L2, z.B. Kabel, können somit einfach in die jeweilige Aufnahme A, A1-A6 eingeschoben werden, um im Inneren der Klemme 1 einen elektrischen Kontakt herzustellen und zugleich daran festgehalten zu werden. Diese Funktionsweise wird weiter unten noch näher erläutert werden. Zum Lösen der Verbindung der elektrischen Leitungen L1 , L2 mit der Klemme 1 umfasst die Klemme jeweils einen Schieber 16, der mittels einem Werkzeug, z.B. dem Werkzeug W, betätigbar ist, vorliegend tiefer in das Gehäuse G geschoben werden kann. The common port A has a larger cross section compared to the individual ports A1-A6. Both the collective connection A and the connections A1-A6 are in the form of push-in connections. The electrical lines L1, L2, e.g. cables, can thus simply be pushed into the respective receptacle A, A1-A6 in order to establish an electrical contact inside the terminal 1 and at the same time to be held on to it. This mode of operation will be explained in more detail further below. To disconnect the electrical lines L1, L2 from the terminal 1, the terminal includes a slide 16 which can be actuated using a tool, e.g. the tool W, which can be pushed deeper into the housing G in the present case.
Neben jedem der Schieber 16 der parallelen Anschlüsse A1-A6 ist eine (optionale) Anzeige 15 angeordnet. Im gezeigten Beispiel ist hierzu jeweils eine LED im Gehäuse G untergebracht. Mittels der Anzeige 15 ist die Stellung des jeweiligen Trennelements 13 anzeigbar. Neben dem Sammelanschluss A (genauer: neben dem Schieber 16 des Sammelanschlusses A) ist eine Öffnung ausgebildet, durch die ein Prüfkontakt 19 zugänglich ist, z.B. um eine am Sammelanschluss A anliegende Spannung zu prüfen. Das Gehäuse G umfasst ein in Fig. 1 und 2 gezeigtes erstes Gehäuseteil 10, welches vorliegend in Form einer Oberschale ausgebildet ist. Das erste Gehäuseteil 10 ist einstückig ausgebildet. Das erste Gehäuseteil 10 ist durch Spritzguss herstellbar und vorliegend hergestellt, und zwar mittels eines Spritzgusswerkzeugs, das aus (genau) zwei Werkzeughälften besteht und keine zusätzlichen Schieber umfasst. An (optional) display 15 is arranged next to each of the sliders 16 of the parallel ports A1-A6. In the example shown, an LED is housed in the housing G for this purpose. The position of the respective separating element 13 can be displayed by means of the display 15 . Next to the bus connection A (more precisely: next to the slider 16 of the bus connection A) there is an opening through which a test contact 19 is accessible, for example in order to test a voltage present at the bus connection A. The housing G comprises a first housing part 10, shown in FIGS. 1 and 2, which in the present case is designed in the form of an upper shell. The first housing part 10 is designed in one piece. The first housing part 10 can be produced by injection molding and is produced in the present case by means of an injection molding tool that consists of (precisely) two tool halves and does not include any additional slides.
Das Gehäuse G umfasst Formschlussmittel, vorliegend zur Ausbildung von Schwalbenschwanzverbindungen, um mit baugleichen Klemmen 1 oder allgemein mit passend ausgebildeten Komponenten formschlüssig verbunden zu werden. So können mehrere Klemmen 1 und/oder weitere Komponenten zu einer längeren Reihe verbunden werden. The housing G includes form-fitting means, in this case for the formation of dovetail joints, in order to be connected in a form-fitting manner to terminals 1 of the same construction or generally to suitably designed components. In this way, several terminals 1 and/or other components can be connected to form a longer row.
An der Oberseite des ersten Gehäuseteils 10 sind Einführöffnungen der Anschlüsse A, A1-A6 angeordnet. Ebenso sind an dieser Oberseite die Trennelemente 13 angeordnet (und, im gezeigten Beispiel, auch die Schieber 16). Ferner ist (optional) an der Oberseite eine Beschriftungsfläche vorgesehen, vorliegend zwischen den Anschlüssen A1-A6 und den zugeordneten Trennelementen 13. Das erste Gehäuseteil 10 bildet jeweils einen Aufnahmeabschnitt 101 von jeder der Aufnahmen R aus. Insertion openings for the terminals A, A1-A6 are arranged on the upper side of the first housing part 10 . The separating elements 13 are also arranged on this upper side (and, in the example shown, also the slides 16). Furthermore, an inscription area is (optionally) provided on the upper side, in the present case between the connections A1-A6 and the associated separating elements 13. The first housing part 10 forms a receiving section 101 of each of the receptacles R.
Neben dem (oberen) ersten Gehäuseteil 10 umfasst das Gehäuse G ein (z.B. in Fig. 5 gezeigtes) zweites Gehäuseteil 11 und ein (z.B. in Fig. 4 gezeigtes) drittes Gehäuseteil 12. In addition to the (upper) first housing part 10, the housing G comprises a second housing part 11 (e.g. shown in Fig. 5) and a third housing part 12 (e.g. shown in Fig. 4).
Das erste Gehäuseteil 10 ist im montierten Zustand der Klemme 1 mit dem dritten Gehäuseteil 12 fest verbunden, und zwar konkret formschlüssig. Hierzu umfassen das erste und das dritte Gehäuseteil 10, 12 Rastelemente, sodass die Gehäuseteile 10, 12 einfach, schnell und sicher aneinander befestigt werden können. Vorliegend sind am ersten Gehäuseteil 10 mehrere Öffnungen 106 vorgesehen, konkret in Seitenwänden (die sich im Wesentlichen senkrecht zur Oberseite erstrecken). Am dritten Gehäuseteil 12 sind entsprechende Rastvorsprünge, konkret Rasthaken 120 ausgebildet, die dazu eingerichtet sind, mit den Öffnungen 106 des ersten Gehäuseteils 10 zu verrasten. When the terminal 1 is in the installed state, the first housing part 10 is firmly connected to the third housing part 12, specifically in a form-fitting manner. For this purpose, the first and the third housing part 10, 12 include locking elements, so that the housing parts 10, 12 can be easily, quickly and securely attached to each other. In the present case, a plurality of openings 106 are provided on the first housing part 10, specifically in side walls (which extend essentially perpendicularly to the top). Corresponding latching projections, specifically latching hooks 120 , which are designed to latch with the openings 106 of the first housing part 10 , are formed on the third housing part 12 .
Fig. 3 zeigt das erste Gehäuseteil 10 separat. Es ist zu erkennen, dass jeder schachtförmige Aufnahmeabschnitt 101 im gezeigten Beispiel einen im Allgemeinen rechteckigen Öffnungsquerschnitt aufweist. An den Seiten der Öffnung der jeweiligen Aufnahmeabschnitte 101 sind allerdings zusätzlich seitliche (optionale) Ausnehmungen 104 vorgesehen, z.B. zur Führung der Trennelemente 13. An den Seiten der Öffnung der jeweiligen Aufnahmeabschnitte 101 sind ferner (optionale) Einführschrägen 103 ausgebildet, um die Trennelemente 13 am Gehäuse G einzurasten. 3 shows the first housing part 10 separately. It can be seen that each shaft-shaped receiving section 101 has a generally rectangular opening cross-section in the example shown. However, lateral (optional) recesses 104 are additionally provided on the sides of the opening of the respective receiving sections 101, for example for guiding the separating elements 13. On the sides of the opening of the respective Receiving sections 101 are also formed (optional) insertion bevels 103 to engage the separating elements 13 on the housing G.
Fig. 4 zeigt das bereits angesprochene dritte Gehäuseteil 12. Das dritte Gehäuseteil 12 ist so ausgestaltet, dass es in das erste Gehäuseteil 10 einsetzbar ist. Für jeden der mit dem Sammelanschluss A elektrisch verbindbaren Anschlüsse A1-A6 umfasst das dritte Gehäuseteil 102 einen Käfig 121. Der Käfig 121 für jeden der Anschlüsse A1-A6 weist Trennwände auf, mittels denen mit den Anschlüssen A1-A6 elektrisch verbundene elektrische Leiter von den benachbarten Anschlüssen und den mit dem Sammelanschluss A elektrisch verbundenen elektrischen Leitern elektrisch isoliert sind. 4 shows the third housing part 12 already mentioned. The third housing part 12 is designed in such a way that it can be inserted into the first housing part 10 . The third housing part 102 includes a cage 121 for each of the terminals A1-A6 that can be electrically connected to the collective terminal A. The cage 121 for each of the terminals A1-A6 has partitions by means of which electrical conductors electrically connected to the terminals A1-A6 are adjacent terminals and the electrical conductors electrically connected to the common terminal A are electrically isolated.
Zwischen dem Käfig 121 von jedem der Anschlüsse A1-A6 und dem Käfig 121 des jeweils benachbarten Anschlusses A1-A6 (bzw. den Käfigen 121 der jeweils benachbarten Anschlüsse A1-A6) ist vorliegend ein Abstand, konkret ein Spalt 122 ausgebildet. In the present case, a distance, specifically a gap 122, is formed between the cage 121 of each of the connections A1-A6 and the cage 121 of the respective adjacent connection A1-A6 (or the cages 121 of the respective adjacent connections A1-A6).
Fig. 5 zeigt das zweite Gehäuseteil 11 der Klemme 1. Das zweite Gehäuseteil 11 ist im montierten Zustand der Klemme 1 zwischen dem ersten Gehäuseteil 10 und dem dritten Gehäuseteil 12 eingefasst. Vorliegend ist das zweite Gehäuseteil 11 in einem durch das erste Gehäuseteil 10 und das dritte Gehäuseteil 12 definierten Innenraum angeordnet. Das zweite Gehäuseteil 11 ist einstückig ausgebildet. Das zweite Gehäuseteil 11 ist durch Spritzguss herstellbar und vorliegend hergestellt, und zwar mittels eines Spritzgusswerkzeugs, das vorzugsweise aus (genau) zwei Werkzeughälften besteht und keine zusätzlichen Schieber umfasst. 5 shows the second housing part 11 of the terminal 1. The second housing part 11 is enclosed between the first housing part 10 and the third housing part 12 when the terminal 1 is in the installed state. In the present case, the second housing part 11 is arranged in an interior space defined by the first housing part 10 and the third housing part 12 . The second housing part 11 is designed in one piece. The second housing part 11 can be produced by injection molding and is produced here by means of an injection molding tool, which preferably consists of (precisely) two tool halves and does not include any additional slides.
Das zweite Gehäuseteil 11 bildet ferner für jedes der Trennelemente 13 einen Aufnahmeabschnitt 111 der entsprechenden Aufnahme R aus. Der Aufnahmeabschnitt 111 des zweiten Gehäuseteils 11 schließt sich an den jeweiligen Aufnahmeabschnitt 101 des ersten Gehäuseteils 10 an. Jeder der Aufnahmeabschnitte 111 wird von Wänden definiert, an denen mehrere Ausnehmungen 112 ausgebildet sind. Vorliegend sind die Ausnehmungen 112 muldenförmig, konkreter: sie beschreiben im Querschnitt einen Kreisbogen. Mehrere dieser Ausnehmungen 112 bilden jeweils einen Abschnitt T 1 eines in Fig. 7 gezeigten Lagerbereichs L für das entsprechende Trennelement 13. The second housing part 11 also forms a receiving section 111 of the corresponding receptacle R for each of the separating elements 13 . The receiving section 111 of the second housing part 11 adjoins the respective receiving section 101 of the first housing part 10 . Each of the receiving portions 111 is defined by walls on which a plurality of recesses 112 are formed. In the present case, the recesses 112 are trough-shaped, more specifically: they describe an arc of a circle in cross section. Several of these recesses 112 each form a section T 1 of a storage area L shown in Fig. 7 for the corresponding separating element 13.
In jedem der Aufnahmeabschnitte 111 sind Halterungen 114 für im Zusammenhang mit Fig. 6 noch näher erläuterte Anschlussleiter 14, 14A-14F ausgebildet. Das zweite Gehäuseteil 11 umfasst ferner mehrere Trennwände 110. Jeweils eine der Trennwände 110 erstreckt sich im montierten Zustand der Klemme 1 in einen der Spalte 122, was eine besonders gute Isolation benachbarter Anschlüsse A, A1-A6 ermöglicht, und damit vergleichsweise hohe Spannungen bei gleichzeitig besonders geringen Abmessungen der Klemme 1. Holders 114 for connection conductors 14, 14A-14F, which will be explained in more detail in connection with FIG. 6, are formed in each of the receiving sections 111. The second housing part 11 also includes a plurality of partitions 110. When the terminal 1 is in the assembled state, one of the partitions 110 extends into one of the gaps 122, which enables particularly good insulation of adjacent connections A, A1-A6, and thus comparatively high voltages at the same time particularly small dimensions of terminal 1.
Ferner umfasst das zweite Gehäuseteil 11 für jeden der Anschlüsse A1-A6 (die über jeweils ein Trennelement 13 mit dem Sammelanschluss A elektrisch verbindbar sind) ein Lager 115 für eine in Fig. 7 gezeigte Kontaktfeder 17. Das zweite Gehäuseteil 11 kann auch als Federhalter bezeichnet werden. Furthermore, the second housing part 11 comprises a bearing 115 for a contact spring 17 shown in FIG will.
Fig. 6 zeigt die Trennelemente 13 in der Kontaktstellung, in der das jeweilige Kontaktmesser 130 beide zugeordneten Kontakte K, K1-K6 elektrisch kontaktiert. Der Kontakt K des Sammelanschlusses A ist dabei an einem Schlitz 140 (in einem vorstehenden Abschnitt) des Sammelanschlussleiters 14 ausgebildet. Die jeweiligen Kontakte K1-K6 der einzelnen Anschlüsse A1-A6 sind jeweils an einem Schlitz 140 (in einem vorstehenden Abschnitt) des entsprechenden Anschlussleiters 14A-14F ausgebildet. 6 shows the separating elements 13 in the contact position in which the respective contact blade 130 makes electrical contact with both associated contacts K, K1-K6. Here, the contact K of the bus terminal A is formed at a slit 140 (in a protruding portion) of the bus terminal conductor 14 . The respective contacts K1-K6 of the individual terminals A1-A6 are each formed at a slit 140 (in a protruding portion) of the corresponding terminal conductor 14A-14F.
Der Sammelanschlussleiter 14 umfasst einen Kontaktbereich 141 , der durch die in den Sammelanschluss A eingesteckte elektrische Leitung L1 elektrisch kontaktierbar ist. The bus connection conductor 14 includes a contact area 141 which can be electrically contacted by the electrical line L1 plugged into the bus connection A.
Jeder der Anschlussleiter 14A-14F umfasst einen Kontaktbereich 141 , der durch die in den entsprechenden Anschluss A1-A6 eingesteckte elektrische Leitung L2 elektrisch kontaktierbar ist. Die der Anschlussleiter 14A-14F sind jeweils U-förmig, wobei der Kontaktbereich 141 und der Abschnitt mit dem Schlitz 140 jeweils einen der beiden Schenkel des U ausbilden. Each of the connection conductors 14A-14F includes a contact area 141, which can be electrically contacted by the electrical line L2 plugged into the corresponding connection A1-A6. The connecting conductors 14A-14F are each U-shaped, with the contact area 141 and the section with the slot 140 each forming one of the two legs of the U.
Die in Fig. 6 gezeigte Anordnung von (Sammel-)Anschlussleitern 14, 14A-14F ist im Inneren der Klemme 1 angeordnet, und zwar zwischen dem ersten, zweiten und dritten Gehäuseteil 10, 11 , 12. The arrangement of (bus) connection conductors 14, 14A-14F shown in Fig. 6 is arranged inside the terminal 1, specifically between the first, second and third housing parts 10, 11, 12.
Fig. 7 und 8 geben einen Blick auf das Innere der Klemme 1 frei. Dabei ist insbesondere zu erkennen, dass das Gehäuse G das erste Gehäuseteil 10 und das zweite Gehäuseteil 11 umfasst, die jeweils einen Abschnitt T1 , T2 des Lagerbereichs L ausbilden. 7 and 8 give a view of the inside of the clamp 1 free. It can be seen in particular that the housing G comprises the first housing part 10 and the second housing part 11, which each form a section T1, T2 of the bearing area L.
Beide Abschnitte T1 , T2 des Lagerbereichs L beschreiben im Querschnitt jeweils einen Kreisbogen von (geringfügig) weniger als einem Halbkreis. Die beiden Abschnitte T1 , T2 des Lagerbereichs L werden durch jeweils eine Ausnehmung 100, 112 im ersten Gehäuseteil 10 und im zweiten Gehäuseteil 11 ausgebildet. Die Ausnehmungen 100, 112 des Lagerbereichs L definieren gemeinsam einen kreiszylindrischen Hohlraum. Both sections T1, T2 of the storage area L each describe a circular arc of (slightly) less than a semicircle in cross section. The two sections T1, T2 of the storage area L are each separated by a recess 100, 112 in the first housing part 10 and formed in the second housing part 11 . The recesses 100, 112 of the storage area L together define a circular-cylindrical cavity.
Im Lagerbereich L ist ein Stift 132 des entsprechenden Trennelements 13 aufgenommen. Konkret umfasst jedes Trennelement 13 beiderseits einen Stift 132 (die koaxial angeordnet sind), der jeweils in einem entsprechenden Lagerbereich L aufgenommen ist. Am Lagerbereich L (konkret: an den Lagerbereichen L) ist das Trennelement 13 um eine Schwenkachse S schwenkbar gelagert. Bei einer Schwenkbewegung um die Schwenkachse S ist das jeweilige T rennelement 13 innerhalb der Aufnahme R bewegbar (und zumindest zum Teil aus der Aufnahme R heraus schwenkbar), in Fig. 7 mittels eines Doppelpfeils veranschaulicht. Die Aufnahme R erstreckt sich hierzu zumindest abschnittsweise senkrecht zur Schwenkachse S. Vorliegend sind alle Trennelemente 13 um koaxiale Schwenkachsen S schwenkbar. In the storage area L, a pin 132 of the corresponding separating element 13 is accommodated. In concrete terms, each separator 13 comprises, on either side, a pin 132 (coaxially arranged) housed in a corresponding bearing area L, respectively. The separating element 13 is pivotably mounted about a pivot axis S on the storage area L (specifically: on the storage areas L). During a pivoting movement about the pivot axis S, the respective separating element 13 can be moved within the receptacle R (and at least partially pivoted out of the receptacle R), illustrated in FIG. 7 by means of a double arrow. For this purpose, the receptacle R extends at least in sections perpendicularly to the pivot axis S. In the present case, all separating elements 13 can be pivoted about coaxial pivot axes S.
Dadurch, dass sowohl das erste Gehäuseteil 10 als auch das zweite Gehäuseteil 11 mit einem Spritzgusswerkzeug ohne Schieber herstellbar sind, weil die Aufnahmeabschnitte 101 , 111 der Lagerbereiche L keine Hinterschneidungen aufweisen, kann das erste Gehäuseteil 10 mit geschlossenen Außenwänden 102 ausgebildet werden, und zwar insbesondere an der Stelle, an der eine gedachte Verlängerung der Schwenkachse S auf die (beiden gegenüberliegenden) Außenwände 102 trifft. Because both the first housing part 10 and the second housing part 11 can be produced with an injection molding tool without a slide, because the receiving sections 101, 111 of the bearing areas L have no undercuts, the first housing part 10 can be formed with closed outer walls 102, in particular at the point where an imaginary extension of the pivot axis S meets the (two opposite) outer walls 102 .
Wie bereits erwähnt sind die Anschlüsse A, A1-A6 in Form von Push-In-Anschlüssen ausgebildet. Hierzu ist für jeden der Anschlüsse A, A1-A6 eine Kontaktfeder 17 vorgesehen. Die Kontaktfeder 17 ist am entsprechenden Lager 115 des zweiten Gehäuseteils 11 gelagert. Die Kontaktfeder 17 umfasst zwei Federschenkel. Eine in den entsprechenden Anschluss A, A1-A6 eingesteckte elektrische Leitung L1 , L2 verdrängt einen Federschenkel der Kontaktfeder 17, gleitet an einer Endkante davon entlang und wird dann durch den Federschenkel der Kontaktfeder 17 elektrisch kontaktierend gegen den entsprechenden Kontaktbereich 141 gedrängt. As already mentioned, the connections A, A1-A6 are in the form of push-in connections. For this purpose, a contact spring 17 is provided for each of the connections A, A1-A6. The contact spring 17 is mounted on the corresponding bearing 115 of the second housing part 11 . The contact spring 17 comprises two spring legs. An electrical line L1, L2 plugged into the corresponding connection A, A1-A6 displaces a spring leg of the contact spring 17, slides along an end edge thereof and is then pushed by the spring leg of the contact spring 17 against the corresponding contact region 141 in an electrically contacting manner.
Um die elektrische Leitung L1 , L2 wieder vom Anschluss A, A1-A6 zu trennen, kann der Schieber 16 tiefer in das Gehäuse G geschoben werden, sodass der Schieber 16 den Federschenkel der Kontaktfeder 17 von der elektrischen Leitung L1 , L2 löst und diese zerstörungsfrei entnommen werden kann. In order to separate the electrical line L1, L2 from the connection A, A1-A6 again, the slide 16 can be pushed deeper into the housing G, so that the slide 16 releases the spring leg of the contact spring 17 from the electrical line L1, L2 and destroys it can be removed.
Die Kombination der Push-In-Anschüsse mit den Aufnahmen R erlaubt eine besonders kompakte Ausführung, da die Entriegelung durch den Schieber 16 besonders platzsparend zwischen der Aufnahme des jeweiligen Anschlusses A1-A6 und der entsprechenden Aufnahme R angeordnet werden kann, und weil die dafür angepasste Form der Anschlussleiter 14A-14F synergetisch zur Kontaktierung der Kontaktfeder 17 eingesetzt werden kann. Die Anschlüsse A1-A6 weisen z.B. einen Nennquerschnitt von etwa 6 mm2 für die einsteckbaren (abisolierten) elektrischen Leitungen L1 auf. The combination of the push-in connections with the recordings R allows a particularly compact design, since the unlocking by the slide 16 is particularly space-saving can be arranged between the receptacle of the respective connection A1-A6 and the corresponding receptacle R, and because the shape of the connection conductors 14A-14F adapted for this purpose can be used synergistically for contacting the contact spring 17. The connections A1-A6 have, for example, a nominal cross section of approximately 6 mm 2 for the pluggable (stripped) electrical lines L1.
Insbesondere anhand von Fig. 7 ist zu erkennen, dass das Gehäuse G eine Unterseite aufweist, an der optional Montagematerial befestigt werden kann, insbesondere je nach Einsatzort angepasstes Montagematerial. Beispielsweise kann an der ebenen Unterseite ein doppelseitiges Klebeband fixiert werden. Alternativ oder zusätzlich können mit in Fig. 7 erkennbaren, beidseitigen Führungen entsprechende Schienen verbunden werden. Ferner ist es möglich, mit den bereits erwähnten Formschlussmitteln Montagebausteine zu verbinden, z.B. mit Montagebausteine mit zumindest einem Schraubloch. Insbesondere da das Gehäuse G abgeschlossen ausführbar ist, ist auch eine fliegende Verbindung in nicht fixierter Montage möglich. It can be seen in particular with reference to FIG. 7 that the housing G has an underside to which mounting material can optionally be fastened, in particular mounting material adapted depending on the place of use. For example, a double-sided adhesive tape can be fixed to the flat underside. As an alternative or in addition, corresponding rails can be connected to guides on both sides, which can be seen in FIG. Furthermore, it is possible to connect assembly blocks with the form-fitting means already mentioned, e.g. with assembly blocks with at least one screw hole. In particular, since the housing G can be designed in a closed manner, a floating connection in non-fixed assembly is also possible.
Die Klemme 1 bildet folglich einen Sammelblock mit Anschlüssen für den Sammelanschlussleiter in Form einer Sammelschiene und davon abgehende Einzelanschlüsse (die Anschlüsse A1-A6), sowie mit einer Trennzone pro Einzelanschluss. Die Klemme 1 kann insbesondere als Potentialsammelblock oder Potentialverteilerblock dienen. The terminal 1 thus forms a common block with connections for the busbar-shaped busbar conductor and individual connections coming from it (connections A1-A6), as well as with an isolating zone per individual connection. Terminal 1 can be used in particular as a potential collection block or potential distribution block.
