Definitions
- the invention relates to a conductor connection terminal with a contact frame and with a clamping spring for clamping an electrical conductor, the contact frame having a busbar section, a partition wall and a wall opening, the clamping spring having a clamping leg with a at least partially arranged in the space between the busbar section and the partition wall has a clamping edge aligned to the busbar section, a spring arch and a contact leg, and the clamping edge and the busbar section form a clamping point for the electrical conductor and an actuating section for opening and closing the clamping point is arranged on the clamping leg of the clamping spring, the actuating section protruding into the wall opening and extends at least in the closed state of the clamping point on a side facing away from the clamping point next to the partition.
- DE 36 37 316 A1 shows a connection terminal with a connection plate and a clamping spring, the clamping spring and the connection plate forming a clamping point for an electrical conductor to be clamped.
- a release element is guided through an opening in the connection plate and rests on a sliding surface of the clamping spring, the release element being set up to open or close the clamping point.
- DE 10 2015 115 791 B4 discloses a conductor connection contact element with a busbar and a clamping spring, the clamping spring being arranged within the busbar piece.
- the busbar piece has two side walls, an actuating section of the clamping spring protruding through a recess on one of the side walls and the actuating section being set up to open and close a clamping point for an electrical conductor to be clamped by means of an actuating tool.
- the object of the present invention is to create an improved conductor connection terminal.
- the conductor connection terminal have an actuating element which is arranged pivotably above the busbar section and is in operative connection with the actuating section of the clamping spring with an actuating finger extending next to the partition wall to the actuating section and is designed to open or close the clamping point.
- actuating element which is arranged pivotably above the busbar section and is in operative connection with the actuating section of the clamping spring with an actuating finger extending next to the partition wall to the actuating section and is designed to open or close the clamping point.
- busbar section and the partition wall are formed in one piece from the contact frame and thus from the same material.
- the busbar section can be formed from a different material than the partition wall.
- the partition wall can consist of a plastic, while the busbar section is made of an electrically conductive metal.
- busbar section functions as an electrically conductive connection and as a partition for the actuating section of the clamping spring, in that it is passed through the wall opening of the partition.
- the clamping point and the actuating section of the clamping spring are thus spatially separated by the busbar section.
- the partition wall can be arranged between the busbar section and the wall opening and the actuating finger can protrude into the wall opening.
- the actuating element can be mounted with a bearing opening and a pin dipping into the position opening. It is also advantageous if the bearing opening is an elongated hole and the pin is mounted displaceably in the elongated hole. In this way, reliable guidance of the actuating element can be provided, which enables the clamping point to be opened or closed.
- the actuating element can be fixable in a self-locking manner in its position in an open and / or a closed position of the clamping point. It is also advantageous if the actuating finger is directed from a pivot bearing area of the actuating element to rest on the actuating section of the clamping spring out of the force direction of the clamping spring pointing towards the pivot bearing area and towards the spring arch, the actuating finger in the open position between one of the clamping legs leading to the pivoting bearing area The perpendicular of the clamping leg and the spring bow rests on the actuating section. In this way, an actuating element can be provided which remains self-locking in the open position without having to rely on additional aids or structural measures.
- the swivel bearing area is the area in which the actuating element can be swiveled into an open position or a closed position.
- the contact leg of the clamping spring can have at least one curvature.
- a curvature of the contact leg relieves the spring root and thus increases the elastic deformability.
- a low overall height can be achieved in that the maximum deflection of the spring can be increased.
- the curvature of the contact leg prevents the spring from falling out of the busbar section.
- no additional fixing elements have to be used. This has the advantage that a conductor connection terminal suitable for bulk material can be provided.
- the curvature of the contact leg of the clamping spring is not limited to one of the embodiments described above and below, but can also be used in other conductor connection terminals in order to achieve a low overall height and / or fixation of the clamping spring without additional elements.
- the contact leg can be supported on a support surface of the contact frame that is diametrically opposite the busbar section. It is also advantageous if the contact leg is held in a form-fitting manner on the support surface. This has the advantage that a conductor connection terminal suitable for bulk material can be provided. It is advantageous if the contact leg is arched. It is conceivable that the contact leg is supported selectively at two points on the bearing surface of the contact frame due to the curvature.
- a plug contact connection for plug contacting of a plug element can be arranged on the contact frame. It is also advantageous if the plug contact connection is a fork contact formed in one piece with the contact frame. In this way, a conductor connection terminal can be provided which enables an electrically conductive connection to a plug contact element inserted into the conductor connection terminal.
- the conductor connection terminal can have an insulating material housing with a conductor insertion opening for inserting the electrical conductor, the contact frame and the actuating element being arranged in the insulating material housing. It is also advantageous if a plurality of contact frames with respectively associated actuating elements and clamping springs are accommodated in the insulating material housing, with a conductor entry opening opening out to a terminal point being in the insulating material housing in each case. Thereby conductor connection terminals with different numbers of poles are conceivable depending on the application.
- the indefinite term "a” is to be understood as such and not as a numerical value.
- the insulating material housing can therefore also have further conductor entry openings, plug contact openings, busbar sections and associated clamping springs, for example for a multi-pole conductor connection terminal.
- FIG. 1 shows a conductor connection terminal 1 in a side sectional view.
- the conductor connection terminal 1 has a contact frame 2 and a clamping spring 3 for clamping an electrical conductor, the clamping spring 3 being arranged on the contact frame 2.
- the contact frame 2 has a busbar section 4 and a partition 5, the partition 5 having a wall opening 6.
- the clamping spring 3 has a clamping leg 7 with a clamping edge 8 aligned with the busbar section 4, the clamping edge 8 and the busbar section 4 forming a clamping point for an electrical conductor to be clamped.
- the clamping spring 3 also has a spring bow 9 which merges into a contact leg 10.
- the busbar section 4 and the partition wall 5 are formed in one piece from the same material. However, it is also conceivable that the partition 5 and the busbar section 4 can be formed from different materials.
- the contact leg 10 rests against the contact frame 2 on the side opposite the busbar section 4 and is arched in this area.
- the contact leg 10 thus does not lie flat on the contact frame 2, but rather only touches it in two points.
- Such a curvature of the contact leg 10 can on the one hand relieve the bending joint so that the number of load changes of the clamping spring 3 can be increased and on the other hand no additional elements are required to hold the clamping spring 3 in the contact frame 2.
- the clamping spring 3 is thus positively connected to the contact frame 2 and thus provides a contact insert suitable for bulk material.
- a plug contact connection 11 for plug contacting of a plug contact element is arranged on the contact frame 2.
- the plug contact connection 11 is in this case as a fork contact formed in one piece with the contact frame 2.
- the clamping point for the electrical conductor to be clamped is formed from the clamping edge 8 of the clamping spring 3 and the busbar section 4, the clamping point being arranged below the actuating element 14 and above the plug contact connection 11.
- the conductor connection terminal 1 has an insulating material housing 12, the contact frame and the clamping spring being arranged as a contact insert in the insulating material housing 12.
- the insulating material housing 12 has a conductor insertion opening 13 for inserting the electrical conductor.
- an actuating element 14 is arranged on the insulating material housing 12, the actuating element 14 being arranged pivotably above the busbar section 4.
- the actuating element 14 is in operative connection with an actuating section (not shown) of the clamping spring 3 in such a way that the actuating element 14 is designed to open or close the clamping point.
- the actuating element has a pin 15, the pin 15 being inserted into a bearing opening 16 in the insulating material housing designed as an elongated hole 12 is immersed and thus the actuating element 14 can be pivotably guided in the bearing opening 16.
- Figure 1 shows the conductor connection terminal 1 in a closed position.
- Figure 2 shows a conductor connection terminal 1 according to Figure 1 in an open position. It becomes clear that the clamping spring 3 has an actuating section 17, the actuating section 17 protruding from the clamping leg 7 of the clamping spring 3. The actuation section 17 protrudes into the wall opening 6 and extends onto a side facing away from the clamping point next to the partition 5.
- the actuating element 14 has an actuating finger 18, the actuating finger 18 extending next to the partition 5 on the side facing away from the clamping point to the actuating section 17 of the clamping spring 3 and being in operative connection with the actuating section 17 such that the actuating element 14 is designed to open or close the clamping point.
- the actuating section 17 is arranged at one end of the clamping leg 7 so that a small actuating force leads to the deflection of the clamping leg 7 of the clamping spring and thus to the opening of the clamping point. This enables simple handling of the conductor connection terminal 1.
- the actuating element 14 can be fixed in the open position in a self-locking manner in that the actuating finger 18 of the actuating element 14 moves from the pivot bearing area in the area of the pin 15 of the actuating element 14 to rest on the actuating section 17 of the clamping spring 3 out of the direction of force of the clamping spring 3 pointing towards the swiveling bearing area and is directed towards the spring arch 9, the actuating finger 18 in the open position between a perpendicular of the clamping leg 7 leading from the clamping leg 7 to the pivot bearing area and the spring arch 9 resting on the actuating section 17.
- the actuating section 14 is thus held in the open position in that the force of the clamping spring 7 acting on the actuating finger 18 counteracts the automatic closing of the actuating element 14.
- Figures 3 and 4 show a contact frame 2 for a conductor connection terminal in a perspective view. It becomes clear that the contact frame is designed in one piece.
- the contact frame 2 is U-shaped, the busbar section 4 merging into the partition 5 and then merging into a contact surface 19 opposite the busbar section 4.
- the partition consists of a material different from the busbar section 4, such as a plastic, in order to electrically isolate the clamping point and the actuating section 17 of the clamping spring from one another.
- Figure 5 shows a clamping spring 3 with a curved contact limb 10, a spring bow 9 and a clamping limb 7, the clamping limb 7 having a clamping edge 8 and an actuating section 17.
- the clamping spring 3 is set up to be inserted in a contact frame 2 in a form-fitting manner.
- the actuating section 17 protrudes into the wall opening 6 of the partition 5 and thus extends to a side of the partition 5 facing away from the clamping point formed between the busbar section 4 and the clamping edge 8, in order to spatially separate the actuating section 17 from the clamping point.
- Figure 6 shows an actuating element 14, the actuating element 14 on the busbar section 4 of a contact frame 2 according to the Figures 3 and 4 can be stored. It is clear that when it is supported on the busbar section 4, the actuating finger 18 of the actuating element next to the partition 5 to the actuating section 17 follows a clamping spring 3 inserted in the contact frame 2 Figure 5 extends and is in operative connection with the actuating section 17 in such a way that the actuating element 14 is set up to open or close the clamping point. The actuating finger 18 can protrude into the wall opening 6 in order to come into operative connection with the actuating section 17 of the clamping spring 3.
- the actuating element has a pin 15 extending transversely to the actuating finger 18, the pin 15 being set up for this purpose to pivot the actuating element 14 on a bearing opening (not shown) of an insulating material housing (not shown).
- the axis of the journal 15 thus forms the pivot bearing area of the actuating element 14.
- actuating finger 18 protrudes laterally along a longitudinal axis L of the actuating element 14 from the side opposite the pin 15 of the pivot bearing area, in order thus to laterally encompass the partition 5 of the contact frame 2.
- the actuating element 14 is therefore only supported via a single pin 15.
- the actuating lever 14 can be mounted with a plurality of pins 15 or in some other way.
- the actuating finger 18 protrudes from a plane that is spanned by the longitudinal axis L and a transverse axis Q of the actuating element 14, so that the actuating element 14 can be fixed self-lockingly on the busbar section 4 of the contact frame 2 in an open or closed position is, wherein a force resulting from the clamping spring 3 counteracts a closing movement of the actuating element 14 in the open position.
- Figure 7 shows a contact insert 20 for use in an insulating housing (not shown) with a contact frame 2 according to the Figures 3 and 4 , a clamping spring 3 according to the Figure 5 and an actuating element 14 according to the Figure 6 , wherein the actuating element 14 rests on the busbar section 4 of the contact frame 2.
- the contact insert 20 is shown in a side view, the side of the partition 5 facing away from the clamping point being visible.
- actuating section 17 of the clamping spring 3 protrudes through the wall opening 6 and extends onto the side facing away from the clamping point. It is also clear that the actuating finger 18 of the actuating element 14 laterally engages around the contact frame 2 and rests on the actuating section 17 of the clamping spring 3.
- the actuating element 14 is shown in an open position.
- the actuating finger 18 of the actuating element 14 is in the area of the pivot bearing area the mounting of the actuating element 14 on the busbar section 4, to rest on the actuating section 17 of the clamping spring 3 out of the direction of force of the clamping spring pointing towards the pivot bearing area and directed towards the spring bow 9, the actuating finger 18 in the open position between one of the clamping legs 7 and the pivot bearing area leading perpendicular 21 of the clamping leg 7 and the spring bow 9 rests on the actuating section 17.
- the actuating element 14 is fixed in the open position in a self-locking manner without additional elements.
- the actuating finger can rest on the actuating section 17 up to the perpendicular 21 of the clamping leg 7 leading from the clamping leg 7 to the pivot bearing area, so that the actuating element 14 can be fixed in the open position in a self-locking manner.
- Figure 8 shows a multi-pole conductor connection terminal 1, wherein a plurality of contact frames 2, each with the associated actuating element 14 and clamping springs (not shown) are accommodated in an insulating material housing 12, with a conductor entry opening 13 opening out to a terminal point being arranged in the insulating material housing 12.
- the conductor connection terminal 1 can have a multi-pole design in order to enable several electrical conductors to be connected at the same time.
- the design of the conductor connection terminal 1 is not limited to a three-pole conductor connection terminal 1; rather, any configuration with regard to the number of poles of such a conductor connection terminal 1 is conceivable.

Description
Die Erfindung betrifft eine Leiteranschlussklemme mit einem Kontaktrahmen und mit einer Klemmfeder zum Anklemmen eines elektrischen Leiters, wobei der Kontaktrahmen einen Stromschienenabschnitt, eine Trennwand und eine Wandöffnung hat, wobei die Klemmfeder einen mindestens teilweise in den Raum zwischen dem Stromschienenabschnitt und der Trennwand angeordneten Klemmschenkel mit einer zum Stromschienenabschnitt ausgerichteten Klemmkante, einen Federbogen und einen Anlageschenkel hat, und die Klemmkante und der Stromschienenabschnitt eine Klemmstelle für den elektrischen Leiter bilden und an dem Klemmschenkel der Klemmfeder ein Betätigungsabschnitt zum Öffnen und Schließen der Klemmstelle angeordnet ist, wobei der Betätigungsabschnitt in die Wandöffnung hineinragt und sich zumindest im geschlossenen Zustand der Klemmstelle auf einer der Klemmstelle abgewandten Seite neben der Trennwand erstreckt.The invention relates to a conductor connection terminal with a contact frame and with a clamping spring for clamping an electrical conductor, the contact frame having a busbar section, a partition wall and a wall opening, the clamping spring having a clamping leg with a at least partially arranged in the space between the busbar section and the partition wall has a clamping edge aligned to the busbar section, a spring arch and a contact leg, and the clamping edge and the busbar section form a clamping point for the electrical conductor and an actuating section for opening and closing the clamping point is arranged on the clamping leg of the clamping spring, the actuating section protruding into the wall opening and extends at least in the closed state of the clamping point on a side facing away from the clamping point next to the partition.
Ausgehend hiervon ist es Aufgabe der vorliegenden Erfindung, eine verbesserte Leiteranschlussklemme zu schaffen.Based on this, the object of the present invention is to create an improved conductor connection terminal.
Die Aufgabe wird durch die Leiteranschlussklemme mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind in den Unteransprüchen beschrieben.The object is achieved by the conductor connection terminal with the features of
Es wird vorgeschlagen, dass die Leiteranschlussklemme ein Betätigungselement hat, das über dem Stromschienenabschnitt schwenkbar angeordnet ist und mit einem sich neben der Trennwand zu dem Betätigungsabschnitt erstreckenden Betätigungsfinger in Wirkverbindung mit dem Betätigungsabschnitt der Klemmfeder steht und zum Öffnen oder Schließen der Klemmstelle ausgebildet ist. Auf diese Weise kann eine hebelbetätigte Leiteranschlussklemme bereitgestellt werden, dessen Anschlussbereich für den elektrischen Leiter und der Hebelbewegungsbereich voneinander getrennt sind und somit unerwünschte Wechselwirkungen vermieden werden können.It is proposed that the conductor connection terminal have an actuating element which is arranged pivotably above the busbar section and is in operative connection with the actuating section of the clamping spring with an actuating finger extending next to the partition wall to the actuating section and is designed to open or close the clamping point. In this way, a lever-operated conductor connection terminal can be provided, the connection area of which for the electrical conductor and the lever movement area are separated from one another and thus undesirable interactions can be avoided.
Es ist denkbar, dass der Stromschienenabschnitt und die Trennwand einstückig aus dem Kontaktrahmen und damit aus dem gleichen Material gebildet sind. Alternativ kann der Stromschienenabschnitt aus einem anderen Material als die Trennwand gebildet sein. So kann die Trennwand beispielsweise aus einem Kunststoff bestehen, während der Stromschienenabschnitt aus einem elektrisch leitenden Metall gefertigt ist.It is conceivable that the busbar section and the partition wall are formed in one piece from the contact frame and thus from the same material. Alternatively, the busbar section can be formed from a different material than the partition wall. For example, the partition wall can consist of a plastic, while the busbar section is made of an electrically conductive metal.
Weiterhin denkbar ist, dass die Funktion des Stromschienenabschnittes und der Trennwand in einem Element vereinigt sind. Der Stromschienenabschnitt fungiert dabei als elektrisch leitende Verbindung und als Trennwand für den Betätigungsabschnitt der Klemmfeder, indem dieser durch die Wandöffnung der Trennwand hindurchgeführt ist. Die Klemmstelle und der Betätigungsabschnitt der Klemmfeder werden damit räumlich durch den Stromschienenabschnitt getrennt.It is also conceivable that the function of the busbar section and the partition are combined in one element. The busbar section functions as an electrically conductive connection and as a partition for the actuating section of the clamping spring, in that it is passed through the wall opening of the partition. The clamping point and the actuating section of the clamping spring are thus spatially separated by the busbar section.
Die Trennwand kann zwischen dem Stromschienenabschnitt und der Wandöffnung angeordnet sein und der Betätigungsfinger in die Wandöffnung hineinragen. Dies hat den Vorteil, dass die Konstruktionsmaße für die erfindungsgemaße Leiteranschlussklemme verringert werden kann, um so eine besonders kompakte Leiteranschlussklemme bereitzustellen.The partition wall can be arranged between the busbar section and the wall opening and the actuating finger can protrude into the wall opening. this has the advantage that the structural dimensions for the conductor connection terminal according to the invention can be reduced in order to provide a particularly compact conductor connection terminal.
Das Betätigungselement kann mit einer Lageröffnung und einem in die Lageöffnung eintauchenden Zapfen gelagert sein. Ferner vorteilhaft ist es, wenn die Lageröffnung ein Langloch ist und der Zapfen verschiebbar in dem Langloch gelagert ist. Auf diese Weise kann eine zuverlässige Führung des Betätigungselementes bereitgestellt werden, die ein Öffnen oder Schließen der Klemmstelle ermöglicht.The actuating element can be mounted with a bearing opening and a pin dipping into the position opening. It is also advantageous if the bearing opening is an elongated hole and the pin is mounted displaceably in the elongated hole. In this way, reliable guidance of the actuating element can be provided, which enables the clamping point to be opened or closed.
Das Betätigungselement kann in einer Offen- und/oder einer Geschlossen-Stellung der Klemmstelle in seiner Position selbsthemmend festlegbar sein. Ferner vorteilhaft ist es, wenn der Betätigungsfinger von einem Schwenklagerbereich des Betätigungselementes zur Auflage auf dem Betätigungsabschnitt der Klemmfeder aus der zum Schwenklagerbereich hinweisenden Kraftrichtung der Klemmfeder heraus und zum Federbogen hin gerichtet ist, wobei der Betätigungsfinger in der Offenposition zwischen einer von dem Klemmschenkel zum Schwenklagerbereich führenden Lotrechten des Klemmschenkels und dem Federbogen auf dem Betätigungsabschnitt aufliegt. Auf diese Weise kann ein Betätigungselement bereitgestellt werden, das selbsthemmend in der Offenposition verbleibt, ohne dabei auf zusätzliche Hilfsmittel oder konstruktive Maßnahmen angewiesen zu sein. Der Schwenklagerbereich ist dabei der Bereich, in dem das Betätigungselement in eine Offenposition oder Geschlossenposition verschwenkt werden kann.The actuating element can be fixable in a self-locking manner in its position in an open and / or a closed position of the clamping point. It is also advantageous if the actuating finger is directed from a pivot bearing area of the actuating element to rest on the actuating section of the clamping spring out of the force direction of the clamping spring pointing towards the pivot bearing area and towards the spring arch, the actuating finger in the open position between one of the clamping legs leading to the pivoting bearing area The perpendicular of the clamping leg and the spring bow rests on the actuating section. In this way, an actuating element can be provided which remains self-locking in the open position without having to rely on additional aids or structural measures. The swivel bearing area is the area in which the actuating element can be swiveled into an open position or a closed position.
Der Anlageschenkel der Klemmfeder kann wenigstens eine Wölbung haben. Durch eine Wölbung des Anlageschenkels wird die Federwurzel entlastet und erhöht damit die elastische Verformbarkeit. So kann zum einen eine geringe Bauhöhe erreicht werden, indem die maximale Auslenkung der Feder gesteigert werden kann. Somit kann das Auftreten von Ermüdungserscheinungen verringert und damit die Häufigkeit der Betätigungen erhöht werden. Zum anderen wird durch die Wölbung des Anlageschenkels ein Herausfallen der Feder aus dem Stromschienenabschnitt verhindert, wobei im Gegensatz zu bekannten Leiteranschlussklemmen keine zusätzlichen Fixierungselemente verwendet werden müssen. Dies hat den Vorteil, dass eine schüttguttaugliche Leiteranschlussklemme bereitgestellt werden kann.The contact leg of the clamping spring can have at least one curvature. A curvature of the contact leg relieves the spring root and thus increases the elastic deformability. On the one hand, a low overall height can be achieved in that the maximum deflection of the spring can be increased. Thus, the occurrence of fatigue can be reduced and thus the frequency of operations can be increased. On the other hand, the curvature of the contact leg prevents the spring from falling out of the busbar section, In contrast to known conductor connection terminals, no additional fixing elements have to be used. This has the advantage that a conductor connection terminal suitable for bulk material can be provided.
Die Wölbung des Anlageschenkels der Klemmfeder ist dabei nicht auf eine der oben beschriebenen und nachfolgenden Ausführungsformen beschränkt, sondern kann vielmehr auch in anderen Leiteranschlussklemmen zum Einsatz kommen, um eine geringe Bauhöhe und/oder eine Fixierung der Klemmfeder ohne zusätzliche Elemente zu erreichen.The curvature of the contact leg of the clamping spring is not limited to one of the embodiments described above and below, but can also be used in other conductor connection terminals in order to achieve a low overall height and / or fixation of the clamping spring without additional elements.
Der Anlageschenkel kann auf einer dem Stromschienenabschnitt diametral gegenüberliegenden Auflagerfläche des Kontaktrahmens aufgelagert sein. Ferner vorteilhaft ist es, wenn der Anlageschenkel formschlüssig an der Auflagerfläche gehalten wird. Dies hat den Vorteil, dass eine schüttguttaugliche Leiteranschlussklemme bereitgestellt werden kann. Dabei ist vorteilhaft, wenn der Anlageschenkel gewölbt ausgebildet ist. Es ist denkbar, dass der Anlageschenkel durch die Wölbung an zwei Stellen der Auflagerfläche des Kontaktrahmens punktuell auflagert.The contact leg can be supported on a support surface of the contact frame that is diametrically opposite the busbar section. It is also advantageous if the contact leg is held in a form-fitting manner on the support surface. This has the advantage that a conductor connection terminal suitable for bulk material can be provided. It is advantageous if the contact leg is arched. It is conceivable that the contact leg is supported selectively at two points on the bearing surface of the contact frame due to the curvature.
An dem Kontaktrahmen kann ein Steckkontaktanschluss zur Steckkontaktierung eines Steckelementes angeordnet sein. Ferner vorteilhaft ist es, wenn der Steckkontaktanschluss ein einstückig mit dem Kontaktrahmen gebildeter Gabelkontakt ist. Auf diese Weise kann eine Leiteranschlussklemme bereitgestellt werden, die eine elektrisch leitende Verbindung mit einem in die Leiteranschlussklemme eingesteckten Steckkontaktelement ermöglicht.A plug contact connection for plug contacting of a plug element can be arranged on the contact frame. It is also advantageous if the plug contact connection is a fork contact formed in one piece with the contact frame. In this way, a conductor connection terminal can be provided which enables an electrically conductive connection to a plug contact element inserted into the conductor connection terminal.
Die Leiteranschlussklemme kann ein Isolierstoffgehäuse mit einer Leitereinführungsöffnung zum Einführen des elektrischen Leiters haben, wobei der Kontaktrahmen und das Betätigungselement in dem Isolierstoffgehäuse angeordnet sind. Ferner vorteilhaft ist es, wenn mehrere Kontaktrahmen mit jeweils zugehörigen Betätigungselementen und Klemmfeder in dem Isolierstoffgehäuse aufgenommen sind, wobei jeweils eine zu einer Klemmstelle ausmündende Leitereinführungsöffnung in dem Isolierstoffgehäuse ist. Es sind damit Leiteranschlussklemmen mit unterschiedlichen Polzahlen je nach Anwendungsfall denkbar.The conductor connection terminal can have an insulating material housing with a conductor insertion opening for inserting the electrical conductor, the contact frame and the actuating element being arranged in the insulating material housing. It is also advantageous if a plurality of contact frames with respectively associated actuating elements and clamping springs are accommodated in the insulating material housing, with a conductor entry opening opening out to a terminal point being in the insulating material housing in each case. Thereby conductor connection terminals with different numbers of poles are conceivable depending on the application.
Der unbestimmte Begriff "ein" ist als solches und nicht als Zahlwert zu verstehen. Das Isolierstoffgehäuse kann daher z.B. für eine mehrpolige Leiteranschlussklemme auch noch weitere Leitereinführungsöffnungen, Steckkontaktöffnungen, Stromschienenabschnitte und zugehörige Klemmfedern haben.The indefinite term "a" is to be understood as such and not as a numerical value. The insulating material housing can therefore also have further conductor entry openings, plug contact openings, busbar sections and associated clamping springs, for example for a multi-pole conductor connection terminal.
Die Erfindung wird nachfolgend beispielhaft mit den beigefügten Zeichnungen näher erläutert. Es zeigen:

Deutlich wird, dass der Anlageschenkel 10 an der dem Stromschienenabschnitt 4 gegenüberliegenden Seite an dem Kontaktrahmen 2 anliegt und in diesem Bereich gewölbt ist. Der Anlageschenkel 10 liegt somit nicht flächig auf dem Kontaktrahmen 2 auf, sondern berührt diesen vielmehr lediglich in zwei Punkten. Durch eine derartige Wölbung des Anlageschenkels 10 kann zum einen das Biegegelenk entlastet werden, sodass die Anzahl der Lastwechsel der Klemmfeder 3 erhöht werden kann und zum anderen keine zusätzlichen Elemente benötigt werden, um die Klemmfeder 3 in dem Kontaktrahmen 2 zu halten. Die Klemmfeder 3 ist somit formschlüssig mit dem Kontaktrahmen 2 verbunden und stellt damit einen schüttguttauglichen Kontakteinsatz bereit.It becomes clear that the
Weiterhin deutlich wird, dass an dem Kontaktrahmen 2 ein Steckkontaktanschluss 11 zur Steckkontaktierung eines Steckkontaktelementes angeordnet ist. Der Steckkontaktanschluss 11 ist dabei als einstückig mit dem Kontaktrahmen 2 gebildeter Gabelkontakt. Zu erkennen ist, dass die Klemmstelle für den anzuklemmenden elektrischen Leiter aus der Klemmkante 8 der Klemmfeder 3 und dem Stromschienenabschnitt 4 gebildet ist, wobei die Klemmstelle unterhalb des Betätigungselementes 14 und oberhalb des Steckkontaktanschlusses 11 angeordnet ist.It is also clear that a
Die Leiteranschlussklemme 1 hat ein Isolierstoffgehäuse 12, wobei der Kontaktrahmen und die Klemmfeder als Kontakteinsatz in dem Isolierstoffgehäuse 12 angeordnet sind. Das Isolierstoffgehäuse 12 hat eine Leitereinführungsöffnung 13 zum Einführen des elektrischen Leiters. Deutlich wird, dass an dem Isolierstoffgehäuse 12 ein Betätigungselement 14 angeordnet ist, wobei das Betätigungselement 14 über dem Stromschienenabschnitt 4 schwenkbar angeordnet ist. Das Betätigungselement 14 steht dabei mit einem Betätigungsabschnitt (nicht dargestellt) der Klemmfeder 3 derart in Wirkverbindung, dass das Betätigungselement 14 zum Öffnen oder Schließen der Klemmstelle ausgebildet ist.The
Weiterhin zu erkennen ist, dass das Betätigungselement einen Zapfen 15 hat, wobei der Zapfen 15 in eine als Langloch ausgebildete Lageröffnung 16 des Isolierstoffgehäuses 12 eintaucht und damit das Betätigungselement 14 schwenkbar in der Lageröffnung 16 geführt werden kann.
Deutlich wird weiterhin, dass das Betätigungselement 14 einen Betätigungsfinger 18 hat, wobei sich der Betätigungsfinger 18 neben der Trennwand 5 auf der der Klemmstelle abgewandten Seite zu dem Betätigungsabschnitt 17 der Klemmfeder 3 erstreckt und mit dem Betätigungsabschnitt 17 derart in Wirkverbindung steht, dass das Betätigungselement 14 zum Öffnen oder Schließen der Klemmstelle ausgebildet ist. Der Betätigungsabschnitt 17 ist dabei an einem Ende des Klemmschenkels 7 angeordnet, damit eine geringe Betätigungskraft zur Auslenkung des Klemmschenkels 7 der Klemmfeder und damit zum Öffnen der Klemmstelle führt. Dies ermöglicht eine einfache Handhabung der Leiteranschlussklemme 1.It is also clear that the
Das Betätigungselement 14 ist in der Offen-Stellung selbsthemmend festlegbar, indem der Betätigungsfinger 18 des Betätigungselementes 14 von dem Schwenklagerbereich im Bereich des Zapfens 15 des Betätigungselementes 14 zur Auflage auf dem Betätigungsabschnitt 17 der Klemmfeder 3 aus der zum Schwenklagerbereich hinweisenden Kraftrichtung der Klemmfeder 3 heraus und zum Federbogen 9 hin gerichtet ist, wobei der Betätigungsfinger 18 in der Offen-Position zwischen einer von dem Klemmschenkel 7 zum Schwenklagerbereich führenden Lotrechten des Klemmschenkels 7 und dem Federbogen 9 auf dem Betätigungsabschnitt 17 aufliegt. Somit wird der Betätigungsabschnitt 14 in der Offen-Stellung gehalten, indem die auf den Betätigungsfinger 18 wirkende Kraft der Klemmfeder 7 einem selbstständigen Schließen des Betätigungselementes 14 entgegenwirkt.The
Alternativ ist aber auch denkbar, dass die Trennwand aus einem von dem Stromschienenabschnitt 4 unterschiedlichem Material wie zum Beispiel einem Kunststoff besteht, um so die Klemmstelle und den Betätigungsabschnitt 17 der Klemmfeder voneinander elektrisch zu isolieren.Alternatively, it is also conceivable that the partition consists of a material different from the
Deutlich wird, dass der Betätigungsfinger 18 seitlich entlang einer Längsachse L des Betätigungselementes 14 von der dem Zapfen 15 gegenüberliegenden Seite von dem Schwenklagerbereich abragt, um somit die Trennwand 5 des Kontaktrahmens 2 seitlich zu umgreifen. Das Betätigungselement 14 ist somit nur über einen einzelnen Zapfen 15 gelagert. Es ist aber auch denkbar, dass der Betätigungshebel 14 mit mehreren Zapfen 15 oder auf eine andere Art gelagert werden kann.It is clear that the
Deutlich wird weiterhin, dass der Betätigungsfinger 18 aus einer Ebene, die durch die Längsachse L und einer Querachse Q des Betätigungselementes 14 aufgespannt wird, herausragt, sodass das Betätigungselement 14 an dem Stromschienenabschnitt 4 des Kontaktrahmens 2 in einer Offen- oder Geschlossen-Stellung selbsthemmend festlegbar ist, wobei eine aus der Klemmfeder 3 resultierende Kraft in der Offen-Position einer Schließbewegung des Betätigungselementes 14 entgegenwirkt.It is also clear that the
Deutlich wird, dass der Betätigungsabschnitt 17 der Klemmfeder 3 durch die Wandöffnung 6 hindurchragt und sich auf die der Klemmstelle abgewandten Seite erstreckt. Weiterhin deutlich wird, dass das der Betätigungsfinger 18 des Betätigungselementes 14 den Kontaktrahmen 2 seitlich umgreift und auf dem Betätigungsabschnitt 17 der Klemmfeder 3 anliegt.It becomes clear that the
Dargestellt ist das Betätigungselement 14 in einer Offenposition. Der Betätigungsfinger 18 des Betätigungselementes 14 ist von dem Schwenklagerbereich, im Bereich der Lagerung des Betätigungselementes 14 auf dem Stromschienenabschnitt 4, zur Auflage auf dem Betätigungsabschnitt 17 der Klemmfeder 3 aus der zum Schwenklagerbereich hinweisenden Kraftrichtung der Klemmfeder heraus und zum Federbogen 9 hin gerichtet, wobei der Betätigungsfinger 18 in der Offenposition zwischen einer von dem Klemmschenkel 7 zum Schwenklagerbereich führenden Lotrechten 21 des Klemmschenkels 7 und dem Federbogen 9 auf dem Betätigungsabschnitt 17 aufliegt. Dadurch ist das Betätigungselement 14 in der Offenposition ohne zusätzliche Elemente selbsthemmend festgelegt. Denkbar ist, dass der Betätigungsfinger bis zur der von dem Klemmschenkel 7 zum Schwenklagerbereich führenden Lotrechten 21 des Klemmschenkels 7 auf dem Betätigungsabschnitt 17 auflagern kann, damit das Betätigungselement 14 selbsthemmend in der Offenposition festlegbar ist.The
