Definitions
- the invention also relates to a method for assembling such a conductor connection terminal.
- DE 10 2013 101 830 A1 discloses a conductor connection terminal with an insulating material housing and a contact insert with a clamping spring, wherein the contact insert can be placed on a housing part and then used in combination in the insulating material housing.
- the object of the present invention is to create an improved conductor connection terminal.
- a second latching connection be arranged between the closure part and the contact insert, the closure part and the contact insert being able to be latched to one another by the second latching connection.
- a conductor connection terminal that can be safely handled can be provided in a preassembled state.
- the double latching namely the closure part with respect to the insulating material housing and the closure part with respect to the contact insert, enables the provision of a pre-assembly unit consisting at least of the closure part and contact insert and a more stable conductor connection terminal. Force influences thus lead to no or reduced deformation of the conductor connection terminal.
- closure part is held securely in the insulating material housing, even in the case of external forces such as tensile or torsional forces that act on the conductor connection terminal.
- the clamping spring can have a contact limb and a spring bow arranged between the contact limb and the clamping limb.
- first and the second latching connection are given.
- the snap-in connections of the conductor connection terminal are not limited to one of these embodiments. Rather, these snap-in connections can also be formed in combination or in an increased number on the conductor connection terminal. For example, it is conceivable that the same type of latching connection is formed at least one, two or three times on the conductor connection terminal according to the invention.
- the second latching connection can be designed as a latching arm of the closure part, the latching arm engaging around the busbar of the contact insert.
- the locking arm is arranged on the closure part.
- the latching arm is guided past the contact insert, the end of the latching arm engaging around the contact insert and thus securely latching the contact insert on the closure part.
- two latching arms can be arranged on the closure part, the latching arms each being guided past opposite sides of the contact insert, the latching arms encompassing the contact insert.
- a latching hook which engages behind a latching edge on the busbar can preferably be provided on the latching arm.
- the insulating material housing can have a blocking element, the blocking element blocking a release of the latching element. It is also conceivable that the insulating material housing itself is the blocking element. If the preassembled closure part with the contact insert is guided into the insulating material housing, the insulating material housing blocks a loosening of the second latching connection.
- the aforementioned design of the second latching connection as latching arms can no longer be deflected, since these are blocked by the presence of the insulating material housing and / or the blocking element. In this way, a functionally reliable and safely handled conductor connection terminal is provided, the second latching connection not being able to be released without the closure part being dismantled from the insulating material housing.
- the first latching connection can be designed as a latching hook of the insulating material housing, the latching hook engaging in an opening in the closure part.
- the latching hook is arranged on the insulating housing. The latching hook can be guided into an opening in the closure part, the latching hook there latching the insulating material housing on the closure part.
- the first latching connection can be designed as a tab of the closure part, the tab engaging around a web on the insulating material housing.
- the tab is arranged on the closure part, the tab being designed as a flat piece of material with a fastening hole.
- the first latching connection can be designed as a projection of the closure part, the projection engaging in a recess of the insulating material housing.
- the projection can in particular be T-shaped.
- the projection is arranged on the closure part, the closure part being guided into a recess in the insulating material housing when the closure part is mounted on the insulating material housing.
- a possible T-shaped configuration of the projection can prevent the first latching connection from being released. The connection can therefore no longer be canceled without destroying the conductor connection terminal.
- Such configurations of the latching connections can occur in any conceivable combination.
- the first latching connection is designed as three projections of the closure part, one of the projections being T-shaped.
- a tab is arranged on the closure part and two latching hooks are arranged on the insulating material housing, which in turn each engage in an opening in the closure part.
- the various combinations of the snap-in connections make it possible to provide a secure conductor connection terminal.
- test opening can be arranged on the closure part.
- the test opening can be aligned transversely to the electrical conductor to be clamped, whereby the test opening extends from a surface of the closure part through the closure part to the contact insert.
- the contact insert can be contacted with external measuring devices through such a test opening.
- the conductor connection terminal can have at least one, preferably two actuation levers, the actuation lever being set up to deflect the clamping leg. This enables the clamping point to be opened and / or closed easily without any further aid.
- the conductor connection terminal can have a guide contour for guiding the first snap-in connection and / or the second snap-in connection.
- the guide contour can be a bevel on the insulating material housing and / or the closure part.
- Such a guide contour simplifies the assembly of the conductor connection terminal.
- the openings of the closure part can have a bevel, with the latching hook of the insulating material housing being able to be guided into the latching position over the bevel.
- the insulating material housing and the closure part can be caulked against one another in the area of the first latching connection. Due to a mechanical caulking of the closure part with respect to the insulating material housing, which causes a plastic deformation of the closure part and / or the insulating material housing, the components can no longer be detached from one another without destroying them with a corresponding expenditure of force.
- the first latching connection and / or the second latching connection can be arranged in a central region of the conductor connection terminal.
- the conductor connection terminal can have a symmetrical structure, the first latching connection and / or the second latching connection being arranged in a plane of symmetry of the conductor connection terminal.
- the first latching connection and / or the second latching connection can be arranged on the plane of symmetry of the conductor connection terminal, the plane of symmetry extending perpendicular to the conductor insertion direction.
- the conductor connection terminal can have two conductor entry openings and two clamping springs, the conductor entry openings being arranged at diametrically opposite ends of the conductor connection terminal.
- the first latching connection and / or the second latching connection can be arranged between the clamping springs of the contact insert.
- the first latching connection between the closure part and the insulating material housing can be provided on diametrically opposite end regions of the conductor connection terminal in the direction of longitudinal extent and thus also outside the plane of symmetry of the conductor connection terminal.
- the direction of longitudinal extension denotes the direction in which the electrical conductors are inserted into the conductor insertion openings.
- a conductor connection terminal with two opposite clamping points for two electrical conductors can be provided, which has a high degree of stability against deformation of the insulating material housing and / or the closure part.
- Such an assembly of the conductor connection terminal according to the invention makes it possible to provide a conductor connection terminal which cannot be dismantled by the action of force from the outside.
- the double latching creates a very stable connection that can no longer be loosened by the subsequent caulking. The user can therefore no longer dismantle the conductor connection terminal, which could impair its function.
- the conductor connection terminal according to the invention has a large number of contact inserts arranged next to one another.
- two, three, four or five contact inserts can be arranged next to one another in an insulating material housing, the contact inserts each having two clamping springs for two electrical conductors to be clamped.
- Figure 1 shows a conductor connection terminal 1 in a perspective view in a first embodiment.
- the base body of the conductor connection terminal 1 is formed from an insulating material housing 2 and a closure part 3, the closure part 3 being inserted into an assembly opening in the insulating material housing 2.
- the conductor connection terminal 1 has two conductor entry openings 4a, 4b for receiving electrical conductors.
- a test opening 6 is arranged on the closure part 3, the test opening 6 extending perpendicularly from a surface of the closure part 3 into the interior of the insulating housing 2. Such a test opening allows access to electrically conductive components within the insulating material housing 2 with external measuring devices.
- the closure part 3 is fixedly connected to the insulating material housing 2 via a first latching connection 7.
- the first latching connection 7 is designed as a projection 8 of the closure part 3, the projection 8 engaging in a recess 9 in the insulating material housing 2 and thus fixing the closure part 3 to the insulating material housing 2.
- the conductor connection terminal 1 is constructed fully symmetrically with respect to a plane of symmetry SE, the first latching connection 7 being arranged in the plane of symmetry SE.
- the plane of symmetry SE extends perpendicular to a conductor insertion direction L.
- FIG 2 shows a closure part 3 of a conductor connection terminal 1 in a perspective view Figure 1 with actuating levers 5a, 5b arranged thereon.
- a second latching connection 10 is arranged on the closure part 3, the second latching connection 10 being designed as a latching arm 11.
- the second latching connection is provided to latch the closure part 3 with a contact insert 12.
- the second locking connection 10 is on the same plane of symmetry SE like the first locking connection 7 is arranged.
- two projections 8 are arranged on opposite sides of the closure part 3 and are provided for engagement in a recess 9 of the insulating material housing 2.
- Figure 3 shows a conductor connection terminal 1 according to Figure 1 in a sectional view, the section lying in the plane of symmetry SE. It can be seen that a busbar 13 of the contact insert 12 is arranged in the interior of the insulating material housing 2, the second latching connection 10 designed as latching arms 11 being passed laterally next to the busbar 13 and encompassing the busbar 13.
- a double latching of the closure part 3 with respect to the contact insert 12 and the insulating material housing 2 is achieved.
- the insulating material housing 2 is designed as a blocking element 14, with part of the insulating material housing 2, preferably a side wall, blocking the release of the second latching connection 10 by preventing the latching arm 11 from being deflected. This means that the latching arms 11 of the second latching connection 10 can only be released from the busbar 13 if the first latching connection 7 is released from the insulating material housing 2 beforehand. The locking arms 11 of the second locking connection 10 are blocked by the presence of the insulating housing 2.
- Figure 4a shows the conductor connection terminal 1 after Figure 1 in a side sectional view.
- the conductor connection terminal has an insulating material housing 2 and a closure part 3, a contact insert 12 being arranged in the interior of the insulating material housing 3.
- the contact insert 12 has a busbar 13 and two clamping springs 17a, 17b, the clamping springs 17a, 17b being arranged on ends of the busbar 13 that are diametrically opposite one another.
- the clamping springs 17a, 17b have a contact leg 18a, 18b which merges into a spring arch 19a, 19b and extends into a clamping leg 20a, 20b.
- the clamping legs 20a, 20b each have a spring clamping edge 21a, 21b, the spring clamping edges 21a, 21b each forming a clamping point with the busbar 13 for an electrical conductor to be clamped.
- the conductor connection terminal 1 has two actuating levers 5a, 5b, one actuating lever 5a, 5b in each case interacting with a clamping spring 17a, 17b, so that the actuating levers 5a, 5b are set up to deflect the clamping legs 20a, 20b.
- a further first latching connection 7a between the closure part 3 and the insulating material housing 3 is designed as a locking hook 22 of the insulating material housing 2.
- the latching hooks 22 are arranged at the diametrically opposite ends of the insulating material housing 2.
- the latching hooks 22 engage in corresponding Openings 23 on the closure part 3 and thus lock the insulating material housing 2 and the closure part 3 with one another.
- This additional latching connection 7a thus takes place at diametrically opposite end regions of the conductor connection terminal 1.
- the additional latching connection 7a is optional and can be omitted if there are few requirements for the latching of the closure part 3 with respect to the insulating material housing 2.
- the further first latching connection 7a can also be secured against loosening of the latching by caulking the projection or also the insulating material housing 2.
- Figure 4b shows an enlarged section of a conductor connection terminal according to FIG. 4a.
- the area of the first latching connection 7a is shown enlarged.
- a bevel 24 is arranged on both the insulating material housing 2 and on the latching hook 7a, 22. These bevels 24 serve as a guide contour for guiding the latching hook 22 of the first latching connection 7a into the opening 23 of the closure part 3. The latching hook slides along the bevels 24 into its latching position and thus fixes the insulating material housing 2 on the closure part 3.
- Figure 5 shows a conductor connection terminal 1 in a second embodiment in a perspective view.
- the conductor connection terminal 1 in Figure 5 is congruent to the conductor connection terminal 1 of the Figure 1 built up.
- the conductor connection terminal 1 in the Figure 5 differs only in the first latching connection 7 to the conductor connection terminal 1 of the Figure 1 .
- the first latching connection 7 is designed as a tab 15, the tab 15 being arranged on the closure part 3 of the conductor connection terminal 1.
- the tab 15 is designed as a flat piece of material with a fastening hole 16.
- a web 17 is arranged on the insulating material housing 2, the tab 15 engaging around the web 17 so that the web 17 latches in the fastening hole 16 and the closure part 3 is thus fixed on the insulating material housing 2.
- Figure 6 a conductor connection terminal 1 in a third embodiment in a perspective view.
- the conductor connection terminal 1 in Figure 6 is congruent to the conductor connection terminal 1 of the Figures 1 and 5 built up.
- the conductor connection terminal 1 in the Figure 6 differs in the design of the first latching connection 7 from the conductor connection terminals 1 of the Figures 1 and 5 .
- the conductor connection terminals 1 according to the second embodiment Figure 5 and third embodiment according to Figure 6 have in addition to the first latching connection 7 preferably also a second latching connection 10 corresponding to the first embodiment according to the Figures 1 to 4 on. Furthermore, the conductor connection terminals of the second and third embodiment preferably additionally or alternatively have the further latching connection 7a in accordance with the Figures 4a and 4b on.
- the first latching connection 7 has three projections 8 on opposite sides of the conductor connection terminal 1, the projections 8 each engaging in a recess 9 of the insulating material housing 2. It can be seen that one of the projections 8 is T-shaped. The T-shaped design of the one projection 8 prevents the wall of the insulating housing 2 from deflecting through the undercut formed in this way of the closure part 3 and the insulating material housing 2 and thus counteracts the detachment of the latching connection 7.
- Figure 7 shows a conductor connection terminal 1 according to Figure 6 in a top view.
- the T-shaped configuration of the projections 8 becomes clear, as a result of which detachment of the closure part 3 from the insulating material housing 2 is made more difficult.
- the recess 9 of the insulating housing 2 is designed in such a way that it engages behind the T-shape of the projection 8 so that the projection 8 is blocked in all degrees of freedom except for one.
- FIG 8 shows a contact insert 12 for use in one of the aforementioned conductor connection terminals 1.
- the contact insert 12 has a busbar 13, with the diametrically opposite ends of the busbar 13 are each a clamping spring 17a, 17b is arranged.
- the clamping springs 17a, 17b each have a contact leg 18a, 18b which merges into a spring arch 19a, 19b and extends into a clamping leg 20a, 20b.
- the clamping limb 20a, 20b extends to the busbar 13, the clamping limb 20a, 20b having a spring clamping edge 21a, 21b and with the busbar 13 forming a clamping point for an electrical conductor to be clamped.
- a conductor receiving section 25 for the electrical conductor to be clamped is arranged in each case at the diametrically opposite ends of the busbar 13. It becomes clear that the conductor receiving sections 25 are designed to be closed on the circumferential side.
- two holding sections 27a, 27b are arranged on a ceiling surface 26 of the busbar 13, the holding sections 27a, 27b each being arranged at the diametrically opposite ends of the ceiling surface 26.
- One of the clamping springs 17a, 17b is in each case suspended in the holding sections 27a, 27b in a self-supporting manner, that is to say without additional fastening means.
- clamping springs 17a, 17b are designed as a single clamping spring with two clamping legs 20a, 20b, the individual clamping spring extending over the top surface 9 of the busbar 13.
- Figure 9 shows a conductor connection terminal 1 in the first embodiment according to Figure 1 in an exploded view. It can be seen that a contact insert 12 according to Figure 8 can be inserted into the insulating housing 2 of the conductor connection terminal 1.
- the closure part 3 is latched onto the busbar 13 of the contact insert 12 by means of the latching arm 11 designed as a second latching connection 10.
- the latching arm 11 engages under the U-shaped busbar 13.

Ferner betrifft die Erfindung ein Verfahren zur Montage einer derartigen Leiteranschlussklemme.The invention also relates to a method for assembling such a conductor connection terminal.
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 mit einer Leiteranschlussklemme mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind in den Unteransprüchen beschrieben.The object is achieved with a conductor connection terminal with the features of
Bei der gattungsgemäßen Leiteranschlussklemme wird vorgeschlagen, dass zwischen dem Verschlussteil und dem Kontakteinsatz eine zweite Rastverbindung angeordnet ist, wobei das Verschlussteil und der Kontakteinsatz durch die zweite Rastverbindung miteinander verrastbar sind.In the case of the generic conductor connection terminal, it is proposed that a second latching connection be arranged between the closure part and the contact insert, the closure part and the contact insert being able to be latched to one another by the second latching connection.
Durch die Ausbildung einer zweiten Rastverbindung zwischen dem Verschlussteil und dem Kontakteinsatz, kann eine sicher zu handhabende Leiteranschlussklemme in einem vormontierten Zustand bereitgestellt werden. Die zweifache Verrastung, nämlich des Verschlussteils gegenüber dem Isolierstoffgehäuse und des Verschlussteils gegenüber dem Kontakteinsatz, ermöglicht die Bereitstellung einer zumindest aus Verschlussteil und Kontakteinsatz bestehenden Vormontageeinheit sowie eine stabilere Leiteranschlussklemme. Krafteinflüsse führen somit zu keinen oder verminderten Verformungen der Leiteranschlussklemme.By forming a second latching connection between the closure part and the contact insert, a conductor connection terminal that can be safely handled can be provided in a preassembled state. The double latching, namely the closure part with respect to the insulating material housing and the closure part with respect to the contact insert, enables the provision of a pre-assembly unit consisting at least of the closure part and contact insert and a more stable conductor connection terminal. Force influences thus lead to no or reduced deformation of the conductor connection terminal.
Weiterhin wird das Verschlussteil sicher in dem Isolierstoffgehäuse, auch bei äußeren Kräften wie zum Beispiel Zug- oder Torsionskräfte, die auf die Leiteranschlussklemme wirken, gehalten.Furthermore, the closure part is held securely in the insulating material housing, even in the case of external forces such as tensile or torsional forces that act on the conductor connection terminal.
Die Klemmfeder kann einen Anlageschenkel und einen zwischen dem Anlageschenkel und Klemmschenkel angeordneten Federbogen haben.The clamping spring can have a contact limb and a spring bow arranged between the contact limb and the clamping limb.
Im Folgenden werden verschiedene Ausführungsformen der ersten und der zweiten Rastverbindung angeführt. Die Rastverbindungen der Leiteranschlussklemme sind nicht auf eine dieser Ausführungsformen begrenzt. Vielmehr können diese Rastverbindungen auch in Kombination oder in einer erhöhten Anzahl an der Leiteranschlussklemme ausgebildet sein. So ist zum Beispiel denkbar, dass dieselbe Art der Rastverbindung wenigstens ein, zwei oder drei Mal an der erfindungsgemäßen Leiteranschlussklemme ausgebildet ist.In the following, various embodiments of the first and the second latching connection are given. The snap-in connections of the conductor connection terminal are not limited to one of these embodiments. Rather, these snap-in connections can also be formed in combination or in an increased number on the conductor connection terminal. For example, it is conceivable that the same type of latching connection is formed at least one, two or three times on the conductor connection terminal according to the invention.
Die zweite Rastverbindung kann als Rastarm des Verschlussteils ausgebildet sein, wobei der Rastarm die Stromschiene des Kontakteinsatzes umgreift. Der Rastarm ist dabei an dem Verschlussteil angeordnet. Beim montieren des Verschlussteils und des Kontakteinsatzes wird der Rastarm an dem Kontakteinsatz vorbeigeführt, wobei das Ende des Rastarmes den Kontakteinsatz umgreift und den Kontakteinsatz damit sicher an dem Verschlussteil verrastet. Dabei kann es sinnvoll sein, dass an dem Verschlussteil zwei Rastarme angeordnet sind, wobei die Rastarme jeweils an gegenüberliegenden Seiten des Kontakteinsatzes vorbeigeführt werden, wobei die Rastarme den Kontakteinsatz umgreifen. Vorzugsweise kann an dem Rastarm ein Rasthaken vorgesehen sein, der eine Rastkante an der Stromschiene hintergreift.The second latching connection can be designed as a latching arm of the closure part, the latching arm engaging around the busbar of the contact insert. The locking arm is arranged on the closure part. When assembling the closure part and the contact insert, the latching arm is guided past the contact insert, the end of the latching arm engaging around the contact insert and thus securely latching the contact insert on the closure part. It can be useful here for two latching arms to be arranged on the closure part, the latching arms each being guided past opposite sides of the contact insert, the latching arms encompassing the contact insert. A latching hook which engages behind a latching edge on the busbar can preferably be provided on the latching arm.
Das Isolierstoffgehäuse kann ein Blockierelement haben, wobei das Blockierelement ein Lösen des Rastelementes blockiert. Denkbar ist auch, dass das Isolierstoffgehäuse selbst das Blockierelement ist. Wird das vormontierte Verschlussteil mit dem Kontakteinsatz in das Isolierstoffgehäuse geführt, blockiert das Isolierstoffgehäuse ein Lösen der zweiten Rastverbindung.The insulating material housing can have a blocking element, the blocking element blocking a release of the latching element. It is also conceivable that the insulating material housing itself is the blocking element. If the preassembled closure part with the contact insert is guided into the insulating material housing, the insulating material housing blocks a loosening of the second latching connection.
So können zum Beispiel die vorgenannte Ausbildung der zweiten Rastverbindung als Rastarme nicht mehr ausgelenkt werden, da diese durch das Vorhandensein des Isolierstoffgehäuses und/oder des Blockierelementes blockiert werden. Auf diese Weise wird eine funktionssichere und sicher zu handhabende Leiteranschlussklemme bereitgestellt, wobei die zweite Rastverbindung nicht gelöst werden kann, ohne dass das Verschlussteil von dem Isolierstoffgehäuse demontiert wird.For example, the aforementioned design of the second latching connection as latching arms can no longer be deflected, since these are blocked by the presence of the insulating material housing and / or the blocking element. In this way, a functionally reliable and safely handled conductor connection terminal is provided, the second latching connection not being able to be released without the closure part being dismantled from the insulating material housing.
Die erste Rastverbindung kann als Rasthaken des Isolierstoffgehäuses ausgebildet sein, wobei der Rasthaken in eine Öffnung im Verschlussteil eingreift. Der Rasthaken ist dabei an dem Isolierstoffgehäuse angeordnet. Der Rasthaken kann in eine Öffnung des Verschlussteils geführt werden, wobei der Rasthaken dort das Isolierstoffgehäuse an dem Verschlussteil verrastet.The first latching connection can be designed as a latching hook of the insulating material housing, the latching hook engaging in an opening in the closure part. The latching hook is arranged on the insulating housing. The latching hook can be guided into an opening in the closure part, the latching hook there latching the insulating material housing on the closure part.
Es ist denkbar, dass zwischen dem Verschlussteil und dem Isolierstoffgehäuse ein gewisser Abstand besteht, so dass das Verschlussteil bei Montage des Isolierstoffgehäuses an das Verschlussteil durchfedern kann.It is conceivable that there is a certain distance between the closure part and the insulating material housing, so that the closure part can spring through when the insulating material housing is mounted on the closure part.
Die erste Rastverbindung kann als Lasche des Verschlussteils ausgebildet sein, wobei die Lasche einen Steg am Isolierstoffgehäuse umgreift. Die Lasche ist dabei an dem Verschlussteil angeordnet, wobei die Lasche als flaches Materialstück mit einem Befestigungsloch ausgebildet ist. Bei der Montage des Verschlussteils an das Isolierstoffgehäuse wird die Lasche über den Steg des Isolierstoffgehäuses geführt, wobei der Steg in das Befestigungsloch gelangt und dort das Verschlussteil an das Isolierstoffgehäuse verrastet.The first latching connection can be designed as a tab of the closure part, the tab engaging around a web on the insulating material housing. The tab is arranged on the closure part, the tab being designed as a flat piece of material with a fastening hole. When assembling the closure part on the insulating material housing, the tab is guided over the web of the insulating material housing, the web entering the fastening hole and there the closure part latches onto the insulating material housing.
Die erste Rastverbindung kann als Vorsprung des Verschlussteils ausgebildet sein, wobei der Vorsprung in eine Ausnehmung des Isolierstoffgehäuses eingreift. Der Vorsprung kann insbesondere T-förmig ausgebildet sein. Der Vorsprung ist dabei an dem Verschlussteil angeordnet, wobei das Verschlussteil bei der Montage des Verschlussteils an das Isolierstoffgehäuse in eine Ausnehmung des Isolierstoffgehäuses geführt wird. Eine mögliche T-förmige Ausgestaltung des Vorsprunges kann ein Lösen der ersten Rastverbindung verhindern. Die Verbindung kann somit nicht mehr ohne eine Zerstörung der Leiteranschlussklemme aufgehoben werden.The first latching connection can be designed as a projection of the closure part, the projection engaging in a recess of the insulating material housing. The projection can in particular be T-shaped. The projection is arranged on the closure part, the closure part being guided into a recess in the insulating material housing when the closure part is mounted on the insulating material housing. A possible T-shaped configuration of the projection can prevent the first latching connection from being released. The connection can therefore no longer be canceled without destroying the conductor connection terminal.
Derartige Ausgestaltungen der Rastverbindungen können in jeder denkbaren Kombination auftreten. So ist zum Beispiel denkbar, dass die erste Rastverbindung als drei Vorsprünge des Verschlussteils ausgebildet ist, wobei eine der Vorsprünge T-förmig ausgebildet ist. Es ist aber auch denkbar, dass an dem Verschlussteil eine Lasche angeordnet ist und an dem Isolierstoffgehäuse zwei Rasthaken, die wiederum jeweils in eine Öffnung des Verschlussteils eingreifen. Durch die verschiedenen Kombinationen der Rastverbindungen kann eine handlungssichere Leiteranschlussklemme bereitgestellt werden.Such configurations of the latching connections can occur in any conceivable combination. For example, it is conceivable that the first latching connection is designed as three projections of the closure part, one of the projections being T-shaped. However, it is also conceivable that a tab is arranged on the closure part and two latching hooks are arranged on the insulating material housing, which in turn each engage in an opening in the closure part. The various combinations of the snap-in connections make it possible to provide a secure conductor connection terminal.
An dem Verschlussteil kann eine Prüföffnung angeordnet sein. Die Prüföffnung kann dabei quer zum anzuklemmenden elektrischen Leiter ausgerichtet sein, wobei sich die Prüföffnung von einer Oberfläche des Verschlussteils durch das Verschlussteil hindurch zum Kontakteinsatz hin erstreckt. Durch eine derartige Prüföffnung kann der Kontakteinsatz mit externen Messgeräten kontaktiert werden.A test opening can be arranged on the closure part. The test opening can be aligned transversely to the electrical conductor to be clamped, whereby the test opening extends from a surface of the closure part through the closure part to the contact insert. The contact insert can be contacted with external measuring devices through such a test opening.
Die Leiteranschlussklemme kann zumindest einen, vorzugsweise zwei Betätigungshebel haben, wobei der Betätigungshebel zur Auslenkung des Klemmschenkels eingerichtet ist. Dies ermöglicht ein einfaches Öffnen und/oder Schließen der Klemmstelle ohne eines weiteren Hilfsmittels.The conductor connection terminal can have at least one, preferably two actuation levers, the actuation lever being set up to deflect the clamping leg. This enables the clamping point to be opened and / or closed easily without any further aid.
Die Leiteranschlussklemme kann eine Führungskontur zur Führung der ersten Rastverbindung und/oder der zweiten Rastverbindung haben. Insbesondere kann die Führungskontur eine Fase am Isolierstoffgehäuse und/oder Verschlussteil sein. Durch eine derartige Führungskontur wird die Montage der Leiteranschlussklemme vereinfacht. So können zum Beispiel die Öffnungen des Verschlussteils eine Fase haben, wobei der Rasthaken des Isolierstoffgehäuses über die Fase in Rastposition geführt werden kann.The conductor connection terminal can have a guide contour for guiding the first snap-in connection and / or the second snap-in connection. In particular, the guide contour can be a bevel on the insulating material housing and / or the closure part. Such a guide contour simplifies the assembly of the conductor connection terminal. For example, the openings of the closure part can have a bevel, with the latching hook of the insulating material housing being able to be guided into the latching position over the bevel.
Das Isolierstoffgehäuse und das Verschlussteil können im Bereich der ersten Rastverbindung gegeneinander verstemmt sein. Durch eine mechanische Verstemmung des Verschlussteils gegenüber dem Isolierstoffgehäuse, die eine plastische Verformung des Verschlussteils und/oder des Isolierstoffgehäuses bewirkt, können die Bauteile nicht mehr voneinander gelöst werden, ohne diese durch einen entsprechenden Kraftaufwand zu zerstören.The insulating material housing and the closure part can be caulked against one another in the area of the first latching connection. Due to a mechanical caulking of the closure part with respect to the insulating material housing, which causes a plastic deformation of the closure part and / or the insulating material housing, the components can no longer be detached from one another without destroying them with a corresponding expenditure of force.
Die erste Rastverbindung und/oder die zweite Rastverbindung können in einem Mittelbreich der Leiteranschlussklemme angeordnet sein. Die Leiteranschlussklemme kann dabei einen symmetrischen Aufbau haben, wobei die erste Rastverbindung und/oder die zweite Rastverbindung in einer Symmetrieebene der Leiteranschlussklemme angeordnet sind. Insbesondere können die erste Rastverbindung und/oder die zweite Rastverbindung auf der Symmetrieebene der Leiteranschlussklemme angeordnet sein, wobei die Symmetrieebene sich senkrecht zur Leitereinführungsrichtung erstreckt.The first latching connection and / or the second latching connection can be arranged in a central region of the conductor connection terminal. The conductor connection terminal can have a symmetrical structure, the first latching connection and / or the second latching connection being arranged in a plane of symmetry of the conductor connection terminal. In particular, the first latching connection and / or the second latching connection can be arranged on the plane of symmetry of the conductor connection terminal, the plane of symmetry extending perpendicular to the conductor insertion direction.
Auf diese Weise kann eine vollsymmetrische Leiteranschlussklemme bereitgestellt werden, wobei die Fertigung einer derartigen vollsymmetrischen Leiteranschlussklemme vereinfacht wird.In this way, a fully symmetrical conductor connection terminal can be provided, the manufacture of such a fully symmetrical conductor connection terminal being simplified.
Die Leiteranschlussklemme kann zwei Leitereinführungsöffnungen und zwei Klemmfedern haben, wobei die Leitereinführungsöffnungen an einander diametral gegenüberliegenden Enden der Leiteranschlussklemme angeordnet sind. Insbesondere können die erste Rastverbindung und/oder die zweite Rastverbindung zwischen den Klemmfedern des Kontakteinsatzes angeordnet sein. Alternativ oder zusätzlich kann insbesondere die erste Rastverbindung zwischen dem Verschlussteil und dem Isolierstoffgehäuse an in Längserstreckungsrichtung diametral gegenüberliegenden Endbereichen der Leiteranschlussklemme vorgesehen werden und somit auch außerhalb der Symmetrieebene der Leiteranschlussklemme. Die Längserstreckungsrichtung bezeichnet dabei die Richtung in welcher die elektrischen Leiter in die Leitereinführungsöffnungen eingeführt werden.The conductor connection terminal can have two conductor entry openings and two clamping springs, the conductor entry openings being arranged at diametrically opposite ends of the conductor connection terminal. In particular, the first latching connection and / or the second latching connection can be arranged between the clamping springs of the contact insert. Alternatively or additionally, in particular the first latching connection between the closure part and the insulating material housing can be provided on diametrically opposite end regions of the conductor connection terminal in the direction of longitudinal extent and thus also outside the plane of symmetry of the conductor connection terminal. The direction of longitudinal extension denotes the direction in which the electrical conductors are inserted into the conductor insertion openings.
So kann eine Leiteranschlussklemme mit zwei gegenüberliegenden Klemmstellen für zwei elektrische Leiter bereitgestellt werden, die eine hohe Stabilität gegen Verformung des Isolierstoffgehäuses und/oder des Verschlussteils hat. Dies bedeutet insbesondere, dass sich das Isolierstoffgehäuse und/oder das Verschlussteil unter Krafteinwirkung, zum Beispiel unter Zug auf eingesteckte elektrische Leiter, nicht plastisch und/oder elastisch verformt und die Bauteile in Ihrer Position zueinander sicher gehalten werden.In this way, a conductor connection terminal with two opposite clamping points for two electrical conductors can be provided, which has a high degree of stability against deformation of the insulating material housing and / or the closure part. This means in particular that the insulating material housing and / or the closure part are not plastically and / or elastically deformed under the action of force, for example under tension on inserted electrical conductors, and the components are held securely in their position relative to one another.
Eine der oben genannten Leiteranschlussklemmen kann nach einem Verfahren mit den folgenden Schritten montiert werden:
- Befestigung der Klemmfeder an der Stromschiene,
- Verrastung des Kontakteinsatzes am Verschlussteil,
- Einsetzen des Verschlussteils in die Montageöffnung des Isolierstoffgehäuses,
- Fixierung des Isolierstoffgehäuses an dem Verschlussteil,
- Verstemmung des Verschlussteils gegen das Isolierstoffgehäuse im Bereich der ersten Rastverbindung.
- Attachment of the clamping spring to the busbar,
- Latching of the contact insert on the closure part,
- Insertion of the closure part into the assembly opening of the insulating housing,
- Fixation of the insulating material housing on the closure part,
- Caulking of the closure part against the insulating housing in the area of the first latching connection.
Durch eine derartige Montage der erfindungsgemäßen Leiteranschlussklemme kann eine Leiteranschlussklemme bereitgestellt werden, die nicht durch Krafteinwirkung von außen demontiert werden kann. Durch die doppelte Verrastung wird eine sehr stabile Verbindung hergestellt, die durch das anschließende Verstemmen nicht mehr gelöst werden kann. Der Benutzer kann somit die Leiteranschlussklemme nicht mehr demontieren, wodurch die Funktion beeinträchtigt werden könnte.Such an assembly of the conductor connection terminal according to the invention makes it possible to provide a conductor connection terminal which cannot be dismantled by the action of force from the outside. The double latching creates a very stable connection that can no longer be loosened by the subsequent caulking. The user can therefore no longer dismantle the conductor connection terminal, which could impair its function.
Der unbestimmte Begriff "ein" ist als solcher und nicht als Zahlwort zu verstehen. So ist auch denkbar, dass die erfindungsgemäße Leiteranschlussklemme eine Vielzahl von nebeneinander angeordneten Kontakteinsätzen hat. Dabei können zum Beispiel zwei, drei, vier oder fünf Kontakteinsätze nebeneinander in einem Isolierstoffgehäuse angeordnet sein, wobei die Kontakteinsätze jeweils zwei Klemmfedern für zwei anzuklemmende elektrische Leiter haben.The indefinite term "a" is to be understood as such and not as a numerical word. It is also conceivable that the conductor connection terminal according to the invention has a large number of contact inserts arranged next to one another. For example, two, three, four or five contact inserts can be arranged next to one another in an insulating material housing, the contact inserts each having two clamping springs for two electrical conductors to be clamped.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen beispielhaft mit den beigefügten Zeichnungen näher erläutert. Es zeigen:

Weiterhin zu erkennen sind zwei Betätigungshebel 5a, 5b, wobei die Betätigungshebel 5a, 5b an dem Verschlussteil 3 angeordnet sind. An dem Verschlussteil 3 ist eine Prüföffnung 6 angeordnet, wobei sich die Prüferöffnung 6 von einer Oberfläche des Verschlussteils 3 senkrecht in den Innenraum des Isolierstoffgehäuses 2 erstreckt. Durch eine derartige Prüföffnung kann der Zugang zu elektrisch leitenden Bauteilen innerhalb des Isolierstoffgehäuses 2 mit externen Messgeräten ermöglicht werden.Two
Deutlich wird, dass das Verschlussteil 3 über eine erste Rastverbindung 7 mit dem Isolierstoffgehäuse 2 fixiert verbunden ist. Die erste Rastverbindung 7 ist dabei als Vorsprung 8 des Verschlussteils 3 ausgebildet, wobei der Vorsprung 8 in eine Ausnehmung 9 des Isolierstoffgehäuse 2 eingreift und das Verschlussteil 3 damit mit dem Isolierstoffgehäuse 2 fixiert.It becomes clear that the
Erkennbar ist, dass die Leiteranschlussklemme 1 in Bezug auf eine Symmetrieebene SE vollsymmetrisch aufgebaut ist, wobei die erste Rastverbindung 7 in der Symmetrieebene SE angeordnet ist. Die Symmetrieebene SE erstreckt sich dabei senkrecht zu einer Leitereinführungsrichtung L.It can be seen that the
Weiterhin zu erkennen ist, dass an einander gegenüberliegenden Seiten des Verschlussteils 3 zwei Vorsprünge 8 angeordnet sind, die zum Eingriff in eine Ausnehmung 9 des Isolierstoffgehäuses 2 vorgesehen sind.It can also be seen that two
Deutlich wird, dass das Isolierstoffgehäuse 2 als Blockierelement 14 ausgebildet ist, wobei ein Teil des Isolierstoffgehäuses 2, vorzugsweise eine seitliche Wandung ein Lösen der zweiten Rastverbindung 10 blockiert, indem ein Auslenken des Rastarms 11 verhindert wird. Das bedeutet, dass die Rastarme 11 der zweiten Rastverbindung 10 nur von der Stromschiene 13 gelöst werden können, wenn die erste Rastverbindung 7 von dem Isolierstoffgehäuse 2 zuvor gelöst wird. Die Rastarme 11 der zweiten Rastverbindung 10 werden durch das Vorhandensein des Isolierstoffgehäuses 2 blockiert.It is clear that the insulating

Der Kontakteinsatz 12 hat eine Stromschiene 13 und zwei Klemmfedern 17a, 17b, wobei die Klemmfedern 17a, 17b an einander diametral gegenüberliegenden Enden der Stromschiene 13 angeordnet sind. Die Klemmfedern 17a, 17b haben einen Anlageschenkel 18a, 18b, der in einen Federbogen 19a, 19b übergeht und sich in einen Klemmschenkel 20a, 20b erstreckt. Die Klemmschenkel 20a, 20b haben jeweils eine Federklemmkante 21a, 21 b, wobei die Federklemmkanten 21a, 21b mit der Stromschiene 13 jeweils eine Klemmstelle für einen anzuklemmende elektrischen Leiter bilden.The
Die Leiteranschlussklemme 1 hat zwei Betätigungshebel 5a, 5b, wobei jeweils ein Betätigungshebel 5a, 5b mit einer Klemmfeder 17a, 17b in Wechselwirkung steht, sodass die Betätigungshebel 5a, 5b zur Auslenkung der Klemmschenkel 20a, 20b eingerichtet sind.The
Deutlich wird, dass eine weitere erste Rastverbindung 7a zwischen dem Verschlussteil 3 und dem Isolierstoffgehäuse 3 als Rasthaken 22 des Isolierstoffgehäuses 2 ausgebildet ist. Die Rasthaken 22 sind dabei an den diametral gegenüberliegenden Enden des Isolierstoffgehäuses 2 angeordnet. Die Rasthaken 22 greifen dabei in korrespondierende Öffnungen 23 am Verschlussteil 3 ein und verrasten somit das Isolierstoffgehäuse 2 und das Verschlussteil 3 miteinander. Diese zusätzliche Rastverbindung 7a erfolgt somit an diametral gegenüberliegenden Endbereichen der Leiteranschlussklemme 1. Die zusätzliche Rastverbindung 7a ist optional und kann bei geringen Anforderungen an die Verrastung des Verschlussteils 3 gegenüber dem Isolierstoffgehäuse 2 entfallen. Auch die weitere erste Rastverbindung 7a kann durch eine Verstemmung des Vorsprunges oder auch des Isolierstoffgehäuses 2 gegen ein Lösen der Verrastung gesichert werden.It becomes clear that a further
Die erste Rastverbindung 7 ist als Lasche 15 ausgebildet, wobei die Lasche 15 am Verschlussteil 3 der Leiteranschlussklemme 1 angeordnet ist. Die Lasche 15 ist als flaches Materialstück mit einem Befestigungsloch 16 ausgebildet. An dem Isolierstoffgehäuse 2 ist ein Steg 17 angeordnet, wobei die Lasche 15 den Steg 17 umgreift, sodass der Steg 17 in dem Befestigungsloch 16 verrastet und das Verschlussteil 3 damit an dem Isolierstoffgehäuse 2 fixiert.The

Die erste Rastverbindung 7 hat auf sich einander gegenüberliegenden Seiten der Leiteranschlussklemme 1 jeweils drei Vorsprünge 8, wobei die Vorsprünge 8 jeweils in eine Ausnehmung 9 des Isolierstoffgehäuses 2 eingreifen. Zu erkennen ist das einer der Vorsprünge 8 T-förmig ausgebildet ist. Die T-förmige Ausbildung des einen Vorsprungs 8 verhindert durch den so gebildeten Hinterschnitt von Verschlussteil 3 und Isolierstoffgehäuse 2 eine Auslenkung der Wandung des Isolierstoffgehäuses 2 und wirkt somit einer Lösung der Rastverbindung 7 entgegen.The
Wird zusätzlich der nicht blockierte Freiheitsgrad durch einen anderen Vorsprung 8 blockiert, ist ein Lösen des Verschlussteils 3 von dem Isolierstoffgehäuse 2 nicht mehr möglich, ohne die Leiteranschlussklemme 1 zu zerstören.If the unblocked degree of freedom is additionally blocked by another
Zu erkennen ist, dass jeweils an den diametral gegenüberliegenden Enden der Stromschiene 13 ein Leiteraufnahmeabschnitt 25 für den anzuklemmenden elektrischen Leiter angeordnet ist. Deutlich wird, dass die Leiteraufnahmeabschnitte 25 umfangsseitig geschlossen ausgebildet sind.It can be seen that a
Weiterhin zu erkennen ist, dass an einer Deckenfläche 26 der Stromschiene 13 zwei Halteabschnitte 27a, 27b angeordnet sind, wobei sich die Halteabschnitte 27a, 27b jeweils an den diametral gegenüberliegenden Enden der Deckenfläche 26 angeordnet sind. In den Halteabschnitten 27a, 27b ist jeweils eine der Klemmfeder 17a, 17b selbsttragend, das bedeutet ohne zusätzliche Befestigungsmittel, eingehängt.It can also be seen that two holding
Es ist aber auch denkbar, dass die Klemmfedern 17a, 17b als eine einzelne Klemmfeder mit zwei Klemmschenkeln 20a, 20b ausgebildet sind, wobei sich die einzelne Klemmfeder über die Deckenfläche 9 der Stromschiene 13 erstreckt.However, it is also conceivable that the clamping springs 17a, 17b are designed as a single clamping spring with two clamping
Deutlich wird, wie eine erfindungsgemäße Leiteranschlussklemme 1 montiert werden kann. In einem ersten Schritt wird das Verschlussteil 3 mittels des als zweite Rastverbindung 10 ausgebildeten Rastarms 11 an der Stromschiene 13 des Kontakteinsatzes 12 verrastet. Der Rastarm 11 untergreift dabei die U-förmig gebildete Stromschiene 13.It becomes clear how a
In einem zweiten Schritt können die Betätigungshebel 5a, 5b an dem Verschlussteil 3 und dem Kontakteinsatz 12 montiert werden. Dieser zweite Schritt kann auch optional vor dem ersten Schritt erfolgen.In a second step, the
In einem dritten Schritt kann die Vormontageeinheit mit dem Verschlussteil 3, dem Kontakteinsatz 12 und den Betätigungshebeln 5a, 5b in das Isolierstoffgehäuse 2 durch eine Montageöffnung 28 in das Isolierstoffgehäuse 2 eingesetzt werden. Dabei wird das Isolierstoffgehäuse 2 an dem Verschluss 3 durch die erste Rastverbindung 7 und die weitere erste Rastverbindung 7a fixiert. Die erste Rastverbindung 7 ist dabei an dem Verschlussteil 3 angeordnet und die weitere erste Rastverbindung 7a an dem Isolierstoffgehäuse 2.In a third step, the pre-assembly unit with the
Deutlich wird, dass die erste Rastverbindung 7 in eine entsprechende Ausnehmung 9 am Isolierstoffgehäuse 2 eingreift. Dabei wird das Verschlussteil 3 an dem Isolierstoffgehäuse 2 fixiert. Die weiteren ersten Rastverbindungen 7a unterstützen diese Fixierung zusätzlich. Die Ausnehmung 9 ist dabei umfangsseitig geschlossen ausgebildet. Das bedeutet insbesondere, dass die erste Rastverbindung 7 nur in einem Freiheitsgrad in die Ausnehmung 9 geführt werden kann.It becomes clear that the
In einem optionalen vierten Schritt kann das Verschlussteil 3 gegen das Isolierstoffgehäuse 2 im Bereich der ersten Rastverbindung 7 und/oder der weiteren ersten Rastverbindung 7a verstemmt werden.In an optional fourth step, the
