Definitions
- the invention relates to a conductor connecting terminal with an insulating material housing and at least one spring-loaded terminal connection for making electrical contact with an electrical conductor inserted through a conductor insertion opening of the insulating material housing, the at least one spring-loaded terminal connection having at least one busbar and at least one clamping spring which has at least one clamping leg for clamping the electrical conductor against one Clamping point of the busbar and a contact leg for supporting the clamping spring, the conductor terminal also having at least one pivotally mounted actuating element for opening and closing the spring-loaded terminal connection by acting on an actuating area of the clamping spring, the at least one actuating element along a linear and formed in the insulating material housing / or arcuate guideway for guiding the pivoting movement of the B is guided by the actuating element, an actuating force acting on the actuating element in an actuating direction can be deflected into an actuating direction of the clamping spring that deviates from the actuating direction by at least 150 degrees.
- a generic conductor terminal is, for example, from the EP 1 670 098 B1 known.
- wire connection terminals with an actuating element for example in the form of an actuating lever, are also known from the WAGO product range.
- From the DE 20 2015 103 176 U1 shows a terminal block wiring device.
- From the DE 10 2013 104 394 A1 shows a conductor terminal.
- From the DE 20 2004 019 109 U1 shows a connection device for electrical conductors with actuator.
- the invention is based on the object of specifying a more universally applicable and at the same time very compact conductor terminal.
- the direction of action of the clamping spring can differ, for example, in the range from 170 to 190 degrees from the direction of actuation of the actuating element.
- the conductor terminal according to the invention is thus very universally applicable and can e.g. can be used for terminal blocks, connecting terminals or as a connection terminal of an electrical connector.
- the at least one actuating element is guided along a linear and / or arcuate guideway formed in the insulating material housing for guiding the pivoting movement of the actuating element.
- This has the advantage that the actuating element in combination with a linear and / or curved guideway formed in the insulating material housing enables a large number of design options for the conductor connection terminal, such as either lever actuation or pusher actuation, optionally different actuation directions of the actuation element, in particular actuation directions which differ significantly from the direction of insertion of an electrical conductor into the conductor connection terminal, and actuation directions which can be selected independently of the position and configuration of the clamping spring.
- the direction of action of the actuating force of an actuating tool i.e. the direction of actuation cannot be tracked when the actuating element is pivoted, so that particularly convenient and ergonomic operation is possible even with a tool-actuated design of the conductor connecting terminal.
- the guideway is formed in the insulating material housing and is therefore separated from the clamping spring with regard to its position and component assignment.
- the clamping spring does not have to be designed to guide the actuating element, which allows greater degrees of freedom in determining the design of the clamping spring without having to consider the guidance of the actuating element.
- the guideway can be completely linear or completely arcuate, i.e. arched, be trained.
- the guideway can also be linear piece by piece and curved piece by piece.
- the actuating element is guided on the guideway during its pivoting movement and is supported thereon in relation to the actuating force acting on the actuating element and possibly also in relation to a reaction force acting on the actuating element by the clamping spring.
- the actuating element can have an arc contour corresponding to the arc shape of the guideway, via which the actuating element bears at least in sections on an arcuate region of the guideway.
- the actuating element can also rest completely on the guideway.
- the actuating element is supported with respect to the actuating force exclusively on the linear and / or arcuate guideway formed in the insulating material housing. In this way, a favorable guidance and support of the actuating element without applying other elements such.
- the actuating element is designed to execute a sliding movement with respect to the guideway. This has the advantage that complex types of actuation of the conductor connection terminal can advantageously be implemented by designing the guideway.
- the actuating element can be mounted directly on the slide in the slide. This has the advantage that no separate bearing is required for the mounting of the actuating element.
- the guideway is arranged at least two at an angle to one another has essentially linear guideway sections on which the actuating element is guided in a sliding manner.
- the actuating element has at least two support points arranged on its outer contour, which are spaced apart and by means of which the actuating element is supported against the actuating force at two substantially linear guideway sections arranged at an angle to one another. This also promotes favorable low-friction guidance of the actuating element during the sliding pivoting movement.
- the actuating element can be guided along a two-dimensional path, as a result of which the actuating force acting on the actuating element is deflected accordingly in a direction of action of the clamping spring.
- the actuating element in particular possible to design the actuating element so small and compact that it is arranged completely within the space enclosed by the insulating material housing of the conductor connection terminal so that it does not protrude outwards.
- the actuating element can nevertheless be actuated from the outside through a corresponding actuating opening of the conductor connecting terminal, e.g. through a tool.
- the spring-loaded terminal connection can advantageously also be arranged entirely in the insulating material housing.
- the actuating element has at least one passage area, through which an electrical conductor inserted through the conductor insertion opening can be guided in a straight line through an area surrounded by the actuating element to the clamping point.
- the actuating element has two outer guide legs, via which the actuating element is supported on the guideway and between which the passage area is arranged.
- This has the advantage that the actuating element can be made very robust despite the passage area and is guided symmetrically in a mechanically favorable manner. In this way, the actuating element can be provided in a simple and inexpensive manner despite the through opening, e.g. as a plastic injection molded part. If, as mentioned above, the actuating element has an arc contour corresponding to the arc shape of the guideway, this can be implemented in such a way that the outer guide legs have the arc contour corresponding to the guideway.
- the actuating element has a groove or notch for receiving an actuating tool, via which the actuating element can be actuated to open and close the spring-loaded terminal connection.
- an actuating tool For example, a screwdriver can be used as an operating tool, the blade of which is inserted into the groove or notch.
- the conductor connection terminal has a manually actuable actuation lever with a grip area protruding from the insulating material housing, the actuation lever being fastened to the conductor connection terminal and being set up to actuate the actuating element to open and close the spring-loaded terminal connection.
- the conductor terminal is can be designed either for a tool actuation or for a lever actuation, in fact with an essentially identical design of the other individual parts, in particular of the actuating element.
- the actuating lever can be lockable, so that a once selected position of the spring clamp connection, ie opened or closed, is maintained until the actuating lever is actuated again.
- the actuating lever can be mounted, for example, with a separate bearing on the insulating housing, for example on a cover part of the insulating housing.
- the clamping spring has a separate actuating leg and / or at least one actuating section of the clamping leg and / or at least one actuating section arranged between the contact leg and the clamping leg as the actuating area.
- the conductor terminal can also be designed very universally with regard to the clamping spring, e.g. with an essentially U-shaped clamping spring.
- clamping springs can advantageously be used which have a spring arch between the clamping leg and the contact leg. It is advantageous here to provide the actuating section between the spring arch and the clamping leg or on part of the clamping leg.
- the conductor connection terminal has an insertion direction of an electrical conductor, in which the electrical conductor inserted through the conductor insertion opening can be guided in a straight line to the clamping point, and the actuating element can be actuated in an actuating direction which is at least 60 Degree, in particular at least 80 degrees, deviates from the direction of insertion of the electrical conductor.
- the actuating element can be actuated in an actuating direction which is at least 60 Degree, in particular at least 80 degrees, deviates from the direction of insertion of the electrical conductor.
- the guideway is not completely circular.
- the guideway can also be arranged at points in the insulating material housing that would otherwise not be usable for this.
- edge areas of the insulating material housing can be used to form the guideway.
- the conductor terminal can be made compact overall.
- the guideway is linearly and / or arched piece by piece. This enables many degrees of freedom in determining the guideway and guiding the actuating element.
- the actuating element is arranged entirely within the insulating material housing.
- a compactly constructed conductor connection terminal can be provided without protruding parts of the actuating element.
- the actuating element can be locked, in particular can be locked on the insulating material housing.
- the actuating element can be locked in an open state of the clamping point, so that this open state can be maintained without permanent manual actuation of the actuating element.
- the lock can e.g. can be realized by snapping the actuating element onto an edge or another projection of the insulating material housing.
- the conductor connection terminal has a manually actuable actuating lever, the actuating lever being mounted on the insulating housing with a bearing separate from the mounting of the actuating element.
- a lever-operated conductor connecting terminal can be provided, in which the mechanics of the actuating lever can be designed separately from the mechanics of the actuating element. This allows additional degrees of freedom in the design of the conductor connection terminal.
- the actuating element bears on at least two spaced-apart contact points on the guideway, the actuating element not abutting the guideway between adjacent contact points. In this way, a smooth-running actuating element can be realized, which can be actuated manually with little actuating force.
- the guideway consists of sections of several different or identical geometric shapes arranged one behind the other, eg. B. straight line, circle, ellipse, hyperbola.
- B. straight line, circle, ellipse, hyperbola e.g. B. straight line, circle, ellipse, hyperbola.
- the Figure 1 shows a first connector part 1 on the left and a second connector part 2 on the right.
- the connector parts 1, 2 are assigned to one another as counterparts in order to implement an electrical plug connection when plugged together.
- Each of the connector parts 1, 2 has an insulating housing 10, 11, 12 or 20, 21, 22, in which further elements of the electrical plug connection, such as the conductor connection terminal explained below and the plug contacts in the sense of plug and socket, are arranged.
- the respective insulating housing has a grip area 10, 20 in which the connector parts can be gripped by hand, for example for plugging together and for releasing the plug connection. Further components are accommodated within the grip areas 10, 20, as is still the case is explained.
- the respective insulating material housing 10, 11, 12 or 20, 21, 22 has a plug region 11, 21 on the front side.
- the connector parts 1, 2 are inserted into one another. Accordingly, the one plug-in area 21 is made smaller than the other plug-in area 11, so that the plug-in areas can be plugged together.
- the respective insulating housing has a locking area 12, 22 to which a double-acting locking element can be attached.
- the Figure 2 shows the same connector parts 1, 2 as that Figure 1 , wherein a double-acting locking element 3 is already attached to the connector part 1 shown on the left.
- the locking element 3 has end locking portions, of which in the Figure 2 only the right locking section 32, not yet connected to the second connector part 2, can be seen. Between the locking sections there is a central connecting section 30 of the locking element 3, which at the same time forms an outside of the plug connection and covers the plug connection like an outer side of the housing.
- the locking element 3 On the side facing the plug-in areas 11, 21, the locking element 3 has a central support element 33 in the central connecting section 30, via which the locking element 3 is supported on the plug-in area 11 acting as a counter-bearing.
- the locking by means of the locking element 3 creates a secure connection between the plug-in connector parts 1, 2.
- the connector parts 1, 2 can e.g. be designed as a plug and associated socket, or as other pluggable connector halves.
- the locking element 3 is shown with further details as a single component. As can be seen, the locking element 3 is a separate component that is not part of the first or second connector part 1, 2 is.
- the Figure 3 shows the locking element 3 from an underside, ie a side on which the central support element 33 can be seen.
- the Figure 4 shows the locking element in a side view, similar to that Figure 2 .
- the Figure 5 shows the locking element 3 in a view from above, ie the opposite side of the central support element 33.
- Die Figure 6 shows the locking element 3 in a view of a narrow side.
- the locking element 3 has the central connecting section 30, in which it is designed to be somewhat wider than in the locking sections 31, 32 at the end. On its underside, in addition to the central supporting element 33, there is one with a greater extension length, but a lower overall height than the central one Support element 33 trained stabilizing rib 34 is present, which mechanically stabilizes or stiffens the locking element 3 in the longitudinal direction.
- the locking element 3 initially has a flexible tongue 310, 320, to which a respective latching hook 311, 321 is connected. The regions with a lowered surface contour of the locking element can be formed by the flexible tongues.
- the latching hooks 311, 321 are formed with a slope 312, 322 that rises in the insertion direction into the respective locking area 12, 22 of the connector parts 1, 2, in order to simplify the insertion into the respective locking area 12, 22.
- the respective locking hooks 311, 321 have a locking edge 313, 323 arranged on the side of the locking element 3 opposite the support element 33, with which the locking element 3 locks onto a respective locking bracket area of the locking area 12, 22 of the connector part 1, 2.
- the Figure 7 shows the connector parts 1, 2 in the assembled state, the connector parts 1, 2 being locked together by a locking element 3, as described above. More details of the lock by means of the locking element 3, in particular the sectional drawing of the Figure 8 removable.
- the connector parts 1, 2 in the area of the locking areas 12, 22 have respective latching bracket areas 120, 220, under which the latching hooks 311, 321 are each pushed through and behind which they are hooked with their latching edge 313, 323.
- the insulating-material housings have spaces 16, 26 below the respective latching bracket regions 120, 220 and beyond.
- the latching bracket areas 120, 220 each have a latching bracket extending transversely to the insertion direction of the latching hook 311, 321, under which the latching hook 311, 321 is pushed when the connector parts 1, 2 are assembled with the locking element 3.
- the latching brackets each have an insertion bevel 129, 229.
- the insertion bevels 129, 229 are effective at the beginning of the insertion process of the locking hooks in the respective locking bracket area, i.e. they facilitate the initial insertion of the locking hooks into the respective locking bracket area.
- the housing parts of the connector parts 1, 2 in the area of their respective locking areas 12, 22 have inclined insertion bevels 121, 221 in the insertion direction of the locking element 3, which limit the free space 16, 26 on one side.
- the latching hooks 311, 321 are guided accordingly during insertion, so that they engage in the Figure 8 shown end position when the connector parts 1, 2 together with the locking element 3 are completely plugged together and locked.
- the free end of the respective locking hook 311, 321 of the locking element slides over the insertion bevels 121, 221 during the insertion process, so that the locking hook 311, 321 rests in the end position on the top or outside of the grip area 10, 20 and thus secures the locking position.
- the insertion bevels 121, 221 are thus each arranged at the end of the respective free space 16, 26, as seen in the direction of insertion of the locking element into a connector part 1, 2.
- FIGS. 7 and 8 show with respect to the second connector part 2 as an additional feature a pivotable operating lever 230.
- This operating lever 230 is in the Figure 7 shown twice, in two different swivel positions, in fact it is only available once per spring clamp connection.
- the Figure 8 accordingly shows the operating lever 230 in a closed position, which was explained below
- Figure 9 shows an enlarged detail in the area of the operating lever 230, in which this is shown in the open position.
- the Figure 8 additionally shows the internal structure of the connector parts 1, 2. It can be seen that they each have a conductor connection terminal with a spring-loaded terminal connection.
- a pivotable actuating element 14, 24 is provided in each connector part 1, 2 for actuating the spring-loaded terminal connection, ie for opening and closing the spring-loaded terminal connection.
- the Figure 8 shows on the left, ie with respect to the first connector part 1, the conductor connection terminal contained therein essentially completely, ie with a clamping spring 18, while in the right part, ie the second connector part 2, the clamping spring is not shown for the purpose of illustration. In fact, however, a clamping spring is provided there, which can be arranged there, for example, mirror-symmetrically to the clamping spring 18.
- actuating element 14 has a groove 13, via which actuation can be carried out using a tool.
- the actuating element 24 can also have a groove 23, via which actuation by means of the actuating lever 230 can be carried out.
- the conductor connection terminals present in the respective connector parts 1, 2 can be connected to an electrical conductor via conductor insertion openings 15, 25, which are formed in the respective insulating housing.
- lever actuation Based on Figure 9 let's first go into lever actuation. It can be seen that when the actuating lever 230 is pivoted upward, the actuating element 24 is displaced downward via a plunger region 202 of the actuating lever 230, which acts on the groove 23, and is locked there.
- the plunger region 202 has a contour at its free end which is suitable for engaging in the groove 23 of the actuating element 24.
- the actuating lever 230 is mounted in a housing component 200 of the insulating material housing with an axis 201.
- the housing component 200 of the insulating material housing can be, for example, a component which can be connected to the housing part 20 by means of a latching connection 203.
- the actuating elements 14, 24 can have the same design, irrespective of whether lever actuation or actuation by means of a tool is desired, the desired actuation type can be determined by inserting the appropriate housing component 200 or a housing component 100 for the first connector part 1.
- the Figure 10 shows the conductor terminal of the first connector part 1 in an enlarged view.
- the clamping spring 18 is essentially U-shaped.
- the clamping spring 18 has a contact leg 184, by means of which the clamping spring 18 is supported in the insulating housing, for example in that the clamping spring 18 is suspended from a busbar piece with an arcuate end section 185 of the contact leg 184.
- a spring bend 183 connects to the contact leg 184 of the clamping spring 18.
- a clamping leg 180 connects to the spring arch 183.
- the clamping leg 180 is used to clamp an electrical conductor at a clamping point 170 on the busbar 17.
- An electrical conductor can be guided in a plug-in direction E through the conductor insertion opening 15 in a straight line to the clamping point 170.
- the clamping spring 18 can have, for example in the region of the clamping leg 180, an actuating area 182 in which the clamping spring 18 can be actuated by the actuating element 14 and can thus be deflected upwards.
- the clamping leg 180 is bent away from the busbar 17, so that an electrical conductor can be easily inserted or an already clamped electrical conductor can be easily removed.
- the actuating element 14 has a support and bearing area 143, via which the actuating element 14 is supported in the insulating material housing and executes a sliding pivoting movement when the actuating element 14 moves via the actuating lever 230 or via the groove 13 as a result of an actuation in an actuating direction B becomes.
- a head region of the actuating element 14 formed with the groove 13 slides during the opening movement along an inner wall of the housing oriented essentially perpendicular to the insertion direction E and is supported on the latter. The movement is deflected accordingly and transmitted via a tappet area 140 of the actuating element 14 in a direction of action A to the actuating area 182 of the clamping spring 18.
- the Figure 10 also shows the guideway 19, which in this case is formed by two essentially linear guideway sections 190, 191 arranged at an angle to one another.
- One guideway section 190 is arranged essentially vertically, ie it runs parallel to the actuation direction B of the actuating element 14 on the inside of the housing component 100.
- the second guideway section 191 is arranged horizontally and runs essentially parallel to the insertion direction E of an electrical conductor.
- the second guideway section 191 can be formed on the inside of the lower region of the housing part 10.
- the actuating element 14 is supported on the vertical guideway section 190 with a support point arranged on the head region, which has the groove 13, and on the second, horizontal guideway section 191 with the support and bearing area 143.
- the Figure 11 shows just like that Figure 10 the left part of the conductor connection terminal with the first connector part 1, different elements such as the busbar or parts of the clamping spring not being shown for a better overview compared to FIG. 10.
- the clamping spring 18 are For example, only the clamping leg 180 up to the actuation area 182 and part of the contact leg 184 are shown.
- the actuating element 14 is already actuated in the actuation direction B and, accordingly, the head region with the groove 13 is arranged deeper inside the housing part 10. Accordingly, the clamping spring 18 is deflected upwards by the tappet region 140.
- the actuating element 14 has been slidably moved along the guideway sections 190, 191.
- the Figure 15 shows the electrical connector according to Figure 7 , but here without operating lever 23, in a perspective view. It can be seen that the locking element 3 can have a width which also covers a multipole electrical plug connection, in this case, for example, a two-pole plug connection with two conductor insertion openings 15 arranged next to one another.
- the Figure 12 already shows that with the Figure 8 and enlarged based on the Figure 9 recognizable actuating element 24 in connection with the housing component 200 and the actuating lever 230.
- the actuating lever 230 is again shown here in the open position.
- the actuating element 24 can have a passage area 242 through which an electrical conductor inserted through the conductor insertion opening 25 can be guided in a straight line through an area surrounding the actuating element 24 to the clamping point.
- this passage area 242 is delimited on both sides, ie left and right, by two outer guide legs 241, which have the respective support and bearing area 243 for supporting the actuating element 24 on the insulating material housing.
- the two outer lateral guide legs 241 are connected in the area facing the clamping leg 180 of the clamping spring 18 via a linear actuation section or plunger area 240 which bears against the actuation of the clamping leg 18.
- FIGS Figures 13 and 14 show an alternative embodiment of an actuating element 24 together with the associated actuating lever 230, but here without the housing component 200. It can be seen that the actuating element 24 according to FIGS Figures 13 and 14 is shaped somewhat differently, but also has the passage area 242 with the guide limbs 241 which laterally delimit the passage area and which have the respective support and bearing area 243.
- the Figure 13 shows the arrangement in the closed position, the Figure 14 in the open position.

Description
Die Erfindung betrifft eine Leiteranschlussklemme mit einem Isolierstoffgehäuse und wenigstens einem Federkraftklemmanschluss zur elektrischen Kontaktierung eines durch eine Leitereinführungsöffnung des Isolierstoffgehäuses eingeführten elektrischen Leiters, wobei der wenigstens eine Federkraftklemmanschluss wenigstens eine Stromschiene und wenigstens eine Klemmfeder aufweist, die wenigstens einen Klemmschenkel zum Klemmen des elektrischen Leiters gegen eine Klemmstelle der Stromschiene und einen Anlageschenkel zum Abstützen der Klemmfeder aufweist, wobei die Leiteranschlussklemme ferner wenigstens ein schwenkbar in dem Isolierstoffgehäuse gelagertes Betätigungselement zum Öffnen und Schließen des Federkraftklemmanschlusses durch Beaufschlagung eines Betätigungsbereichs der Klemmfeder aufweist, wobei das wenigstens eine Betätigungselement entlang einer im Isolierstoffgehäuse ausgebildeten linearen und/oder bogenförmigen Führungsbahn zur Führung der Schwenkbewegung des Betätigungselements geführt ist, durch das Betätigungselement eine auf das Betätigungselement in einer Betätigungsrichtung einwirkende Betätigungskraft in eine wenigstens 150 Grad von der Betätigungsrichtung abweichende Beaufschlagungsrichtung der Klemmfeder umlenkbar ist.The invention relates to a conductor connecting terminal with an insulating material housing and at least one spring-loaded terminal connection for making electrical contact with an electrical conductor inserted through a conductor insertion opening of the insulating material housing, the at least one spring-loaded terminal connection having at least one busbar and at least one clamping spring which has at least one clamping leg for clamping the electrical conductor against one Clamping point of the busbar and a contact leg for supporting the clamping spring, the conductor terminal also having at least one pivotally mounted actuating element for opening and closing the spring-loaded terminal connection by acting on an actuating area of the clamping spring, the at least one actuating element along a linear and formed in the insulating material housing / or arcuate guideway for guiding the pivoting movement of the B is guided by the actuating element, an actuating force acting on the actuating element in an actuating direction can be deflected into an actuating direction of the clamping spring that deviates from the actuating direction by at least 150 degrees.
Eine gattungsgemäße Leiteranschlussklemme ist z.B. aus der
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine universeller einsetzbare und zugleich sehr kompakte Leiteranschlussklemme anzugeben.The invention is based on the object of specifying a more universally applicable and at the same time very compact conductor terminal.
Diese Aufgabe wird durch eine Leiteranschlussklemme gemäß Anspruch 1 gelöst. Auf diese Weise sind sehr komplexe Betätigungsrichtungen mit der Leiteranschlussklemme realisierbar. Die Beaufschlagungsrichtung der Klemmfeder kann z.B. im Bereich von 170 bis 190 Grad von der Betätigungsrichtung des Betätigungselements abweichen.This object is achieved by a conductor terminal according to claim 1. In this way, very complex operating directions with the Conductor connection terminal possible. The direction of action of the clamping spring can differ, for example, in the range from 170 to 190 degrees from the direction of actuation of the actuating element.
Die erfindungsgemäße Leiteranschlussklemme ist hierdurch sehr universell einsetzbar und kann z.B. für Reihenklemmen, Verbindungsklemmen oder auch als Anschlussklemme eines elektrischen Steckverbinders genutzt werden.The conductor terminal according to the invention is thus very universally applicable and can e.g. can be used for terminal blocks, connecting terminals or as a connection terminal of an electrical connector.
Wie erwähnt, ist das wenigstens eine Betätigungselement entlang einer im Isolierstoffgehäuse ausgebildeten linearen und/oder bogenförmigen Führungsbahn zur Führung der Schwenkbewegung des Betätigungselements geführt. Dies hat den Vorteil, dass durch das Betätigungselement in Kombination mit einer im Isolierstoffgehäuse ausgebildeten linearen und/oder bogenförmigen Führungsbahn eine Vielzahl von Ausgestaltungsmöglichkeiten der Leiteranschlussklemme ermöglicht werden, wie z.B. wahlweise Hebel-Betätigung oder Drückerbetätigung, wahlweise unterschiedliche Betätigungsrichtungen des Betätigungselements, insbesondere von der Einsteckrichtung eines elektrischen Leiters in die Leiteranschlussklemme deutlich abweichende Betätigungsrichtungen sowie von der Lage und Ausgestaltung der Klemmfeder unabhängig wählbare Betätigungsrichtungen. Insbesondere muss die Wirkrichtung der Betätigungskraft eines Betätigungswerkzeugs, d.h. die Betätigungsrichtung, bei verschwenktem Betätigungselement nicht nachgeführt werden, sodass auch bei einer Werkzeug-betätigbaren Ausführung der Leiteranschlussklemme eine besonders angenehme und ergonomische Bedienung möglich ist.As mentioned, the at least one actuating element is guided along a linear and / or arcuate guideway formed in the insulating material housing for guiding the pivoting movement of the actuating element. This has the advantage that the actuating element in combination with a linear and / or curved guideway formed in the insulating material housing enables a large number of design options for the conductor connection terminal, such as either lever actuation or pusher actuation, optionally different actuation directions of the actuation element, in particular actuation directions which differ significantly from the direction of insertion of an electrical conductor into the conductor connection terminal, and actuation directions which can be selected independently of the position and configuration of the clamping spring. In particular, the direction of action of the actuating force of an actuating tool, i.e. the direction of actuation cannot be tracked when the actuating element is pivoted, so that particularly convenient and ergonomic operation is possible even with a tool-actuated design of the conductor connecting terminal.
Dies wird insbesondere dadurch möglich, dass die Führungsbahn im Isolierstoffgehäuse gebildet ist und somit hinsichtlich ihrer Position und Bauteilzuordnung von der Klemmfeder getrennt ist. Insbesondere muss in diesem Fall nicht die Klemmfeder entsprechend zur Führung des Betätigungselements ausgebildet sein, was größere Freiheitsgrade bei der Festlegung des Designs der Klemmfeder erlaubt, ohne auf die Führung des Betätigungselements Rücksicht nehmen zu müssen.This is made possible in particular by the fact that the guideway is formed in the insulating material housing and is therefore separated from the clamping spring with regard to its position and component assignment. In particular, in this case the clamping spring does not have to be designed to guide the actuating element, which allows greater degrees of freedom in determining the design of the clamping spring without having to consider the guidance of the actuating element.
Die Führungsbahn kann vollständig linear oder vollständig bogenförmig, d.h. gewölbt, ausgebildet sein. Die Führungsbahn kann auch stückweise linear und stückweise bogenförmig ausgebildet sein. Das Betätigungselement ist dabei bei seiner Verschwenkbewegung an der Führungsbahn geführt und daran gegenüber der auf das Betätigungselement einwirkenden Betätigungskraft und ggf. auch gegenüber einer von der Klemmfeder auf das Betätigungselement einwirkenden Reaktionskraft abgestützt. Sofern die Führungsbahn vollständig oder teilweise bogenförmig ausgebildet ist, kann in einer vorteilhaften Ausführungsform das Betätigungselement eine zur Bogenform der Führungsbahn korrespondierende Bogenkontur aufweisen, über die das Betätigungselement zumindest abschnittsweise an einem bogenförmigen Bereich der Führungsbahn anliegt. Das Betätigungselement kann dabei auch vollständig an der Führungsbahn anliegen.The guideway can be completely linear or completely arcuate, i.e. arched, be trained. The guideway can also be linear piece by piece and curved piece by piece. The actuating element is guided on the guideway during its pivoting movement and is supported thereon in relation to the actuating force acting on the actuating element and possibly also in relation to a reaction force acting on the actuating element by the clamping spring. If the guideway is completely or partially arcuate, in an advantageous embodiment the actuating element can have an arc contour corresponding to the arc shape of the guideway, via which the actuating element bears at least in sections on an arcuate region of the guideway. The actuating element can also rest completely on the guideway.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Betätigungselement gegenüber der Betätigungskraft ausschließlich an der im Isolierstoffgehäuse ausgebildeten linearen und/oder bogenförmigen Führungsbahn abgestützt ist. Auf diese Weise wird eine günstige Führung und Abstützung des Betätigungselements ohne Beaufschlagung weiterer Elemente wie z. B. der Stromschiene ermöglicht. Dies erlaubt eine reibungsarme Führung des Betätigungselements während seiner gleitenden Schwenkbewegung.According to an advantageous development of the invention, it is provided that the actuating element is supported with respect to the actuating force exclusively on the linear and / or arcuate guideway formed in the insulating material housing. In this way, a favorable guidance and support of the actuating element without applying other elements such. B. the busbar. This allows the actuating element to be guided with little friction during its sliding pivoting movement.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Betätigungselement zur Ausführung einer Gleitbewegung gegenüber der Führungsbahn ausgebildet ist. Dies hat den Vorteil, dass sich komplexe Betätigungsarten der Leiteranschlussklemme durch Ausbildung der Führungsbahn vorteilhaft realisieren lassen. Das Betätigungselement kann dabei an der Führungsbahn direkt gleitgelagert sein. Dies hat den Vorteil, dass kein separates Lager für die Lagerung des Betätigungselements erforderlich ist.According to an advantageous development of the invention, it is provided that the actuating element is designed to execute a sliding movement with respect to the guideway. This has the advantage that complex types of actuation of the conductor connection terminal can advantageously be implemented by designing the guideway. The actuating element can be mounted directly on the slide in the slide. This has the advantage that no separate bearing is required for the mounting of the actuating element.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Führungsbahn zumindest zwei in einem Winkel zueinander angeordnete im Wesentlichen lineare Führungsbahnabschnitte aufweist, an denen das Betätigungselement gleitend geführt ist. Auf diese Weise kann die erfindungsgemäße, starke Umlenkung von der Betätigungsrichtung in die Beaufschlagungsrichtung der Klemmfeder auf kinematisch günstige Weise realisiert werden, insbesondere ohne ein festes Lagerelement des Betätigungselements.According to an advantageous development of the invention, it is provided that the guideway is arranged at least two at an angle to one another has essentially linear guideway sections on which the actuating element is guided in a sliding manner. In this way, the strong deflection according to the invention from the actuating direction into the direction of action of the clamping spring can be realized in a kinematically favorable manner, in particular without a fixed bearing element of the actuating element.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Betätigungselement wenigstens zwei an seiner Außenkontur angeordnete Abstützstellen aufweist, die voneinander beabstandet sind und über die das Betätigungselement an zwei in einem Winkel zueinander angeordneten im Wesentlichen linearen Führungsbahnabschnitten gegenüber der Betätigungskraft abgestützt ist. Auch hierdurch wird eine günstige reibungsarme Führung des Betätigungselements bei der gleitenden Schwenkbewegung gefördert.According to an advantageous development of the invention, it is provided that the actuating element has at least two support points arranged on its outer contour, which are spaced apart and by means of which the actuating element is supported against the actuating force at two substantially linear guideway sections arranged at an angle to one another. This also promotes favorable low-friction guidance of the actuating element during the sliding pivoting movement.
Auf diese Weise kann das Betätigungselement entlang einer zweidimensionalen Bahn geführt werden, wodurch die auf das Betätigungselement einwirkende Betätigungskraft entsprechend in eine Beaufschlagungsrichtung der Klemmfeder umgelenkt wird.In this way, the actuating element can be guided along a two-dimensional path, as a result of which the actuating force acting on the actuating element is deflected accordingly in a direction of action of the clamping spring.
In einer vorteilhaften Ausführungsform der Erfindung ist es insbesondere möglich, das Betätigungselement derart klein und kompakt auszubilden, dass es vollständig innerhalb des von dem Isolierstoffgehäuse der Leiteranschlussklemme umschlossenen Raums angeordnet ist, sodass es nicht nach außen ragt. Durch eine entsprechende Betätigungsöffnung der Leiteranschlussklemme kann das Betätigungselement dennoch von außen betätigt werden, z.B. durch ein Werkzeug. Vorteilhafterweise kann auch der Federkraftklemmanschluss vollständig im Isolierstoffgehäuse angeordnet sein.In an advantageous embodiment of the invention, it is in particular possible to design the actuating element so small and compact that it is arranged completely within the space enclosed by the insulating material housing of the conductor connection terminal so that it does not protrude outwards. The actuating element can nevertheless be actuated from the outside through a corresponding actuating opening of the conductor connecting terminal, e.g. through a tool. The spring-loaded terminal connection can advantageously also be arranged entirely in the insulating material housing.
Gemäß der Erfindung ist vorgesehen, dass das Betätigungselement wenigstens einen Durchgangsbereich aufweist, durch den ein durch die Leitereinführungsöffnung eingeführter elektrischer Leiter durch einen vom Betätigungselement umgebenen Bereich geradlinig zu der Klemmstelle hin geführt werden kann. Dies hat den Vorteil, dass die Leiteranschlussklemme besonders kompakt ausgebildet werden kann, da insbesondere ein Teil des Betätigungselements zugleich auch einen Leiteraufnahmeraum zur Aufnahme des elektrischen Leiters bilden kann oder Teil eines solchen Leiteraufnahmeraums sein kannAccording to the invention, it is provided that the actuating element has at least one passage area, through which an electrical conductor inserted through the conductor insertion opening can be guided in a straight line through an area surrounded by the actuating element to the clamping point. This has the advantage that the conductor terminal is particularly compact can be formed, since in particular a part of the actuating element can at the same time also form a conductor receiving space for receiving the electrical conductor or can be part of such a conductor receiving space
Gemäß der Erfindung ist vorgesehen, dass das Betätigungselement zwei äußere Führungsschenkel aufweist, über die das Betätigungselement an der Führungsbahn abgestützt ist und zwischen denen der Durchgangsbereich angeordnet ist. Dies hat den Vorteil, dass das Betätigungselement trotz des Durchgangsbereichs sehr robust ausgebildet werden kann und in mechanisch günstiger Weise symmetrisch geführt ist. Auf diese Weise kann das Betätigungselement trotz der Durchgangsöffnung auf einfache und kostengünstige Weise bereitgestellt werden, z.B. als Kunststoff-Spritzgussteil. Sofern, wie oben erwähnt, das Betätigungselement eine zur Bogenform der Führungsbahn korrespondierende Bogenkontur aufweist, kann dies so realisiert sein, dass die äußeren Führungsschenkel die zur Führungsbahn korrespondierende Bogenkontur aufweisen.According to the invention it is provided that the actuating element has two outer guide legs, via which the actuating element is supported on the guideway and between which the passage area is arranged. This has the advantage that the actuating element can be made very robust despite the passage area and is guided symmetrically in a mechanically favorable manner. In this way, the actuating element can be provided in a simple and inexpensive manner despite the through opening, e.g. as a plastic injection molded part. If, as mentioned above, the actuating element has an arc contour corresponding to the arc shape of the guideway, this can be implemented in such a way that the outer guide legs have the arc contour corresponding to the guideway.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Betätigungselement eine Nut oder Einkerbung zur Aufnahme eines Betätigungswerkzeuges aufweist, über das das Betätigungselement zum Öffnen und Schließen des Federkraftklemmanschlusses betätigbar ist. Dies hat den Vorteil, dass das Betätigungselement in definierter Weise durch ein Betätigungswerkzeug bedient werden kann. Es kann z.B. ein Schraubendreher als Betätigungswerkzeug verwendet werden, dessen Klinge in die Nut oder Einkerbung eingesetzt wird.According to an advantageous development of the invention, it is provided that the actuating element has a groove or notch for receiving an actuating tool, via which the actuating element can be actuated to open and close the spring-loaded terminal connection. This has the advantage that the actuating element can be operated in a defined manner by an actuating tool. For example, a screwdriver can be used as an operating tool, the blade of which is inserted into the groove or notch.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Leiteranschlussklemme einen manuell betätigbaren Betätigungshebel mit einem aus dem Isolierstoffgehäuse herausragenden Griffbereich aufweist, wobei der Betätigungshebel an der Leiteranschlussklemme befestigt ist und zur Betätigung des Betätigungselements zum Öffnen und Schließen des Federkraftklemmanschlusses eingerichtet ist. Wie erwähnt, ist die Leiteranschlussklemme wahlweise für eine Werkzeugbetätigung oder für eine Hebelbetätigung auslegbar, und zwar bei im Wesentlichen identischer Ausbildung der übrigen Einzelteile, insbesondere des Betätigungselements. Durch Vorsehen eines Betätigungshebels kann eine werkzeuglose Betätigung der Leiteranschlussklemme realisiert werden, was in manchen Fällen ergonomische Vorteile hat. Insbesondere kann der Betätigungshebel arretierbar sein, sodass eine einmal gewählte Stellung des Federkraftklemmanschlusses, d.h. geöffnet oder geschlossen, beibehalten wird, bis eine erneute Betätigung des Betätigungshebels erfolgt. Der Betätigungshebel kann dabei z.B. mit einer separaten Lagerung am Isolierstoffgehäuse gelagert sein, z.B. an einem Deckelteil des Isolierstoffgehäuses.According to an advantageous further development of the invention, it is provided that the conductor connection terminal has a manually actuable actuation lever with a grip area protruding from the insulating material housing, the actuation lever being fastened to the conductor connection terminal and being set up to actuate the actuating element to open and close the spring-loaded terminal connection. As mentioned, the conductor terminal is can be designed either for a tool actuation or for a lever actuation, in fact with an essentially identical design of the other individual parts, in particular of the actuating element. By providing an actuating lever, tool-free actuation of the conductor connection terminal can be implemented, which has ergonomic advantages in some cases. In particular, the actuating lever can be lockable, so that a once selected position of the spring clamp connection, ie opened or closed, is maintained until the actuating lever is actuated again. The actuating lever can be mounted, for example, with a separate bearing on the insulating housing, for example on a cover part of the insulating housing.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Klemmfeder als Betätigungsbereich einen gesonderten Betätigungsschenkel und/oder wenigstens einen Betätigungsabschnitt des Klemmschenkels und/oder wenigstens einen zwischen dem Anlageschenkel und dem Klemmschenkel angeordneten Betätigungsabschnitt aufweist. Dies hat den Vorteil, dass die Leiteranschlussklemme auch hinsichtlich der Klemmfeder sehr universell ausgestaltet werden kann, z.B. mit einer im Wesentlichen U-förmigen Klemmfeder. Vorteilhafterweise können insbesondere Klemmfedern eingesetzt werden, die zwischen dem Klemmschenkel und dem Anlageschenkel einen Federbogen aufweisen. Hierbei ist es vorteilhaft, den Betätigungsabschnitt zwischen dem Federbogen und dem Klemmschenkel oder an einem Teil des Klemmschenkels vorzusehen.According to an advantageous development of the invention, it is provided that the clamping spring has a separate actuating leg and / or at least one actuating section of the clamping leg and / or at least one actuating section arranged between the contact leg and the clamping leg as the actuating area. This has the advantage that the conductor terminal can also be designed very universally with regard to the clamping spring, e.g. with an essentially U-shaped clamping spring. In particular, clamping springs can advantageously be used which have a spring arch between the clamping leg and the contact leg. It is advantageous here to provide the actuating section between the spring arch and the clamping leg or on part of the clamping leg.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Leiteranschlussklemme eine Einsteckrichtung eines elektrischen Leiters aufweist, in der der durch die Leitereinführungsöffnung eingeführte elektrische Leiter geradlinig zu der Klemmstelle hin geführt werden kann, und das Betätigungselement in einer Betätigungsrichtung betätigbar ist, die um wenigstens 60 Grad, insbesondere wenigstens 80 Grad, von der Einsteckrichtung des elektrischen Leiters abweicht. Auf diese Weise können besonders ergonomische Betätigungsrichtungen der Leiteranschlussklemme realisiert werden, d.h.According to an advantageous development of the invention, it is provided that the conductor connection terminal has an insertion direction of an electrical conductor, in which the electrical conductor inserted through the conductor insertion opening can be guided in a straight line to the clamping point, and the actuating element can be actuated in an actuating direction which is at least 60 Degree, in particular at least 80 degrees, deviates from the direction of insertion of the electrical conductor. In this way, particularly ergonomic actuation directions of the conductor connection terminal can be realized, ie
Betätigungsrichtungen, in denen das gleichzeitige Einführen des elektrischen Leiters nicht durch das Betätigungswerkzeug gehindert wird.Operating directions in which the simultaneous insertion of the electrical conductor is not prevented by the operating tool.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Führungsbahn nicht vollständig kreisbogenförmig ausgebildet ist. Auf diese Weise kann die Führungsbahn auch an Stellen im Isolierstoffgehäuse angeordnet sein, die ansonsten dafür nicht nutzbar wären. Insbesondere können Randbereiche des Isolierstoffgehäuses zur Bildung der Führungsbahn genutzt werden. Hierdurch kann die Leiteranschlussklemme insgesamt kompakt bauend gestaltet werden.According to an advantageous development of the invention, it is provided that the guideway is not completely circular. In this way, the guideway can also be arranged at points in the insulating material housing that would otherwise not be usable for this. In particular, edge areas of the insulating material housing can be used to form the guideway. As a result, the conductor terminal can be made compact overall.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Führungsbahn stückweise linear und/oder bogenförmig ausgebildet ist. Dies ermöglicht viele Freiheitsgrade bei der Festlegung der Führungsbahn und der Führung des Betätigungselements.According to an advantageous development of the invention, it is provided that the guideway is linearly and / or arched piece by piece. This enables many degrees of freedom in determining the guideway and guiding the actuating element.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Betätigungselement vollständig innerhalb des Isolierstoffgehäuses angeordnet ist. Hierdurch kann eine kompakt bauende Leiteranschlussklemme ohne hervorstehende Teile des Betätigungselements bereitgestellt werden.According to an advantageous development of the invention, it is provided that the actuating element is arranged entirely within the insulating material housing. As a result, a compactly constructed conductor connection terminal can be provided without protruding parts of the actuating element.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Betätigungselement arretierbar ist, insbesondere an dem Isolierstoffgehäuse arretierbar. So kann das Betätigungselement beispielsweise in einem geöffneten Zustand der Klemmstelle arretiert werden, so dass dieser geöffnete Zustand auch ohne permanente manuelle Betätigung des Betätigungselements beibehalten werden kann. Die Arretierung kann z.B. durch Einrasten des Betätigungselements an einer Kante oder einem sonstigen Vorsprung des Isolierstoffgehäuses realisiert werden.According to an advantageous development of the invention, it is provided that the actuating element can be locked, in particular can be locked on the insulating material housing. For example, the actuating element can be locked in an open state of the clamping point, so that this open state can be maintained without permanent manual actuation of the actuating element. The lock can e.g. can be realized by snapping the actuating element onto an edge or another projection of the insulating material housing.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Leiteranschlussklemme einen manuell betätigbaren Betätigungshebel aufweist, wobei der Betätigungshebel mit einer von der Lagerung des Betätigungselements separaten Lagerung am Isolierstoffgehäuse gelagert ist. Auf diese Weise kann eine hebelbetätigte Leiteranschlussklemme bereitgestellt werden, bei der die Mechanik des Betätigungshebels getrennt von der Mechanik des Betätigungselements ausgeführt sein kann. Dies erlaubt zusätzliche Freiheitsgrade bei der Gestaltung der Leiteranschlussklemme.According to an advantageous development of the invention, it is provided that the conductor connection terminal has a manually actuable actuating lever, the actuating lever being mounted on the insulating housing with a bearing separate from the mounting of the actuating element. On in this way, a lever-operated conductor connecting terminal can be provided, in which the mechanics of the actuating lever can be designed separately from the mechanics of the actuating element. This allows additional degrees of freedom in the design of the conductor connection terminal.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Betätigungselement an wenigstens zwei voneinander beabstandeten Kontaktstellen an der Führungsbahn anliegt, wobei zwischen benachbarten Kontaktstellen das Betätigungselement nicht an der Führungsbahn anliegt. Auf diese Weise kann ein leichtgängiges Betätigungselement realisiert werden, das mit wenig Betätigungskraft manuell betätigt werden kann.According to an advantageous development of the invention, it is provided that the actuating element bears on at least two spaced-apart contact points on the guideway, the actuating element not abutting the guideway between adjacent contact points. In this way, a smooth-running actuating element can be realized, which can be actuated manually with little actuating force.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Führungsbahn aus hintereinander angeordneten Abschnitten mehrerer unterschiedlicher oder gleicher geometrischer Formen, z. B. Gerade, Kreis, Ellipse, Hyperbel, zusammengesetzt ist. Auf diese Weise können im Isolierstoffgehäuse vorhandene, sonst nicht hierfür nutzbare Bereiche für die Anordnung der Führungsbahn genutzt werden.According to an advantageous development of the invention, it is provided that the guideway consists of sections of several different or identical geometric shapes arranged one behind the other, eg. B. straight line, circle, ellipse, hyperbola. In this way, areas which are otherwise not usable for this purpose in the insulating material housing can be used for the arrangement of the guideway.

Wie erkennbar ist, weist das Verriegelungselement 3 den zentralen Verbindungsabschnitt 30 auf, in dem es etwas breiter ausgebildet ist als in den endseitigen Verriegelungsabschnitten 31, 32. An seiner Unterseite ist außer dem zentralen Abstützelement 33 eine mit größerer Erstreckungslänge, aber geringerer Bauhöhe als das zentrale Abstützelement 33 ausgebildete Stabilisierungsrippe 34 vorhanden, die das Verriegelungselement 3 in Längsrichtung mechanisch stabilisiert oder versteift. In den Verriegelungsabschnitten 31, 32 weist das Verriegelungselement 3 ausgehend vom zentralen Verbindungsabschnitt 30 zunächst eine flexible Zunge 310, 320 auf, an die sich ein jeweiliger Rasthaken 311, 321 anschließt. Durch die flexiblen Zungen können die Bereiche mit abgesenkter Oberflächenkontur des Verriegelungselementes gebildet werden. Darin sind abgeschrägte Abschnitte 319, 329 enthalten, die in Richtung von dem zentralen Verbindungsabschnitt 30 zu dem jeweiligen Rasthaken 311, 321 hin abfallen. Die Rasthaken 311, 321 sind mit einer in Einsteckrichtung in den jeweiligen Verriegelungsbereich 12, 22 der Steckverbinderteile 1, 2 ansteigenden Schräge 312, 322 ausgebildet, um das Einführen in den jeweiligen Verriegelungsbereich 12, 22 zu vereinfachen. Die jeweiligen Rasthaken 311, 321 weisen eine auf der dem Abstützelement 33 gegenüberliegenden Seite des Verriegelungselements 3 angeordnete Rastkante 313, 323 auf, mit der das Verriegelungselement 3 an einem jeweiligen Rastbügelbereich des Verriegelungsbereichs 12, 22 des Steckverbinderteils 1, 2 verrastet.As can be seen, the locking
