Definitions
- the invention relates to a conductor terminal with the features of claim 1.
- Conductor terminals for example in the form of terminal blocks, are for example from the DE 10 2011 110 640 A1 , the DE 10 2013 101409 A1 or the EP 02 53 239 B1 known
- the invention is based on the object of further developing such conductor connection terminals with regard to ergonomics, manufacturing costs and/or ease of assembly.
- the actuating lever automatically adapts to the forces that occur and is therefore subject to reduced wear compared to a fixed axle bearing.
- the floating mounting allows for simple, even subsequent assembly of the actuating lever when the insulating housing is already closed.
- the support of the operating lever on the contact piece which is usually made of metal, offers a robust counter bearing for the operating lever.
- the contact piece together with a corresponding part of the actuating lever, forms a pivot bearing that is very low-wear. Since the actuating lever can advantageously be made of plastic, for example an insulating material of the insulating housing, this also results with the metallic contact piece a favorable pairing of materials that is low-friction and at the same time low-wear.
- the actuating lever at least in certain pivoting angles, can also be supported with its rear side on an inner wall of the insulating material housing.
- the actuating lever can act on the clamping spring directly or indirectly in order to cancel the clamping effect of the clamping spring at the conductor clamping point and not to apply the spring force of the clamping spring to an electrical conductor inserted into the conductor connection terminal, or to open the clamping point.
- the clamping spring can apply the spring force directly to the electrical conductor at the conductor clamping point, in that the clamping spring touches the conductor, or indirectly via an intermediate component.
- the contact piece has a clamping section, in which the contact point is arranged, and a bearing section, on which the actuating lever is at least partially supported in the open position, with the conductor receiving chamber between the clamping section and the bearing section is arranged.
- the clamping spring has a contact leg, via which the clamping spring is supported on a first side of the bearing section, which faces the conductor receiving chamber, on the contact piece. This has the advantage that the clamping spring is securely supported with low material and production costs.
- the actuating lever at least in the open position, is at least partially supported on a second side of the bearing section of the contact piece, facing away from the conductor receiving chamber.
- the bearing section is connected to the clamping section via a connecting section of the contact piece.
- the contact piece with the bearing section and the clamping section can be provided in a simple manner as a one-piece component, e.g. in the form of a stamped and bent part.
- the connecting section can be guided laterally past the area in which the conductor is to be accommodated in the conductor receiving chamber.
- the connecting section can also form a lateral delimitation of the conductor receiving chamber.
- the arrangement of bearing section, connecting section and clamping section can be formed in a U-shape.
- the clamping section, the bearing section and the connecting section can be formed in one piece from a material, in particular metal.
- the bearing section of the contact piece is designed as a plate, in particular as a metal plate.
- the first side of the bearing section and the second side of the bearing section can be spaced apart from one another by the thickness of the plate of the bearing section.
- a closed force chain is formed by a driver element of the clamping spring via a tension arm of the actuating lever acting on the driver element its outer contour, and via the first side and the second side of the bearing section onto the contact leg of the clamping spring.
- the conductor receiving chamber is separated from the actuating lever by the upper section, in particular the bearing section, of the contact piece.
- This has the advantage that the areas of the bearing section and the clamping section are separated by the area of the conductor receiving chamber lying in between. In this way, more favorable construction and space conditions of the conductor terminal are created.
- a pull arm of the actuating lever is arranged between the outer contour of the actuating lever and a grip area of the actuating lever.
- the actuating lever has an eccentric outer contour, via which the actuating lever is supported on the contact piece.
- the pivot bearing contour of the actuating lever is thus formed by the eccentric outer contour.
- the actuating lever can be displaced translationally relative to the insulating material housing and/or the contact piece when it is pivoted in addition to a rotary movement.
- the actuating lever has improved degrees of freedom during the pivoting movement, which in turn is conducive to low-wear storage, easy assembly of the actuating lever in the insulating material housing of the conductor terminal and a pleasant feel during actuation.
- the actuating lever has at least one tension arm which engages behind a driver element of the clamping spring, so that the clamping spring can be deflected by the tension arm when the actuating lever is pivoted into the open position by tensile loading of the clamping spring.
- This has the advantage that the clamping spring can simultaneously exert a reaction force on the actuating lever, which acts on it in the direction of the closed position.
- a self-locking toggle lever principle can be implemented with little effort in this way with regard to the actuating lever, so that little or no additional effort is required to lock it in the open position.
- the clamping spring has a window-like recess into which the pull arm of the actuating lever engages.
- the driver element of the clamping spring can be realized by an upper edge of the window-like recess, or in other words a transverse web of the clamping spring formed there. This allows the clamping spring to be coupled to the tension arm in a simple and inexpensive manner. It is only necessary to produce the window-like recess by punching out a piece of material from the material of the clamping spring.
- a self-coupling system can be created in this way, in which the actuating lever can be inserted into the insulating material housing with the clamping spring already inserted in the insulating material housing and the pull arm can then be inserted into the window-like recess can snap. After this, the pulling arm engages behind the driver element, so that from now on the clamping spring can be actuated by pivoting the actuating lever.
- the conductor connection terminal has first latching means, by which the actuating lever is latched in the open position.
- first latching means by which the actuating lever is latched in the open position.
- the first latching means comprises a first lever latching means which is part of the operating lever and a first contact piece latching means which is part of the contact piece.
- the first lever latching means and the first contact piece latching means cooperate with each other to latch the actuating lever in the open position.
- the first lever locking means can be designed as a groove, trough or other depression in the actuating lever
- the first contact piece locking means can be designed as a protruding nose, contact edge or similar projection adapted to the shape of the first lever locking means.
- a reverse assignment is also advantageous, in that the first lever locking means is in the form of a nose or other projection and the first contact piece locking means is in the form of a groove or other indentation.
- the first contact piece latching means can be formed by the front edge or a rounded front edge at the front end of an upper section of the contact piece pointing toward the actuating lever.
- the conductor connection terminal has second latching means, by means of which the actuating lever is latched in the closed position.
- the second latching means have a second lever latching means, which is part of the actuating lever, and a second housing latching means, which is part of the insulating housing.
- the second lever latch means and the second housing latch means cooperate with each other to latch the operating lever in the closed position.
- the actuating lever has bearing pins which protrude parallel to the axis of rotation of the pivoting movement and which are designed to secure the actuating lever against removal of the actuating lever from the insulating material housing.
- the floating operating lever can be secured in operating situations of the conductor connection terminal in which the operating lever is not otherwise held in the insulating housing, e.g. by the clamping spring.
- the bearing journals do not function, or at least not primarily, for mounting the actuating lever in the insulating material housing for carrying out the pivoting movement, but mainly as a means of securing against removal of the actuating lever from the insulating material housing.
- the insulating material housing has a lever insertion channel for inserting the actuating lever, the lever insertion channel having a guide contour for guiding the bearing journal at least during insertion of the actuating lever.
- the bearing journals have another function, namely a guiding function of the actuating lever during insertion into the insulating material housing.
- the areas of the actuating lever to be arranged in the insulating-material housing place one defined path in it, which is formed by designing the guide contour in such a way that the lever reaches its desired end position in the insulating material housing and is not prevented from being inserted by other components, such as the clamping spring.
- the part of the contact piece on which the actuating lever is supported at least in the open position is designed as a ramp that falls in the direction of rotation of the actuating lever when it is opened.
- the ramp can be in the form of a linear ramp or a non-linear ramp, i.e. with a linearly decreasing contour or with a non-linearly decreasing contour, e.g. a progressively or degressively decreasing contour.
- the assembly of the conductor terminal is understood to mean the assembly of the individual components of the conductor terminal to form the finished, ultimately functional conductor terminal.
- the housing parts of the insulating material housing e.g. two housing half-shells, can be equipped with the components of the contact insert before assembly and then joined together.
- the Figures 1 to 4 show the conductor connection terminal in a side view with the insulating housing open, so that the internal structure can be seen, in different operating positions of the operating lever.
- the figure 1 the conductor terminal in the closed position with no conductor connected
- the figure 2 in closed position with conductor connected
- Figure 3 shows the conductor terminal in the partially open position and the figure 4 in fully open position, each with no conductor connected. The structure and function of the conductor terminal are described below with reference to the Figures 1 to 4 explained in more detail.
- the conductor connection terminal 1 has an insulating material housing 2, which can be designed, for example, as a flat, essentially cuboid housing, so that several conductor connection terminals can be lined up next to one another.
- the insulating material housing 2 can be designed, for example, in the form of two housing half-shells, which are connected to one another after the internal components have been installed.
- the insulating material housing 2 accommodates the inner components, with the open side finally being closed with a cover 9 or an adjacent conductor connection terminal 1 . Accordingly, the Figures 1 to 4 a view of the conductor terminal with the cover part 9 removed.
- the conductor connection terminal 1 has at least one contact piece 3, a clamping spring 5 and an actuating lever 7 as further components.
- the contact piece 3 forms with the clamping spring 5 a contact insert of the conductor terminal 1.
- the clamping spring 5 and the contact piece 3 are, for example, made entirely of electrically conductive material, in particular metal.
- the actuating lever can be made of any material, for example the same material as the insulating material housing 2, for example a plastic material.
- the insulating housing 2 has a conductor insertion opening 6 through which an electrical conductor 8 to be connected can be inserted into the conductor terminal 1 .
- the conductor 8 can be guided with a stripped end 80 first through the conductor insertion opening 6 into a conductor receiving chamber 60, such as that figure 2 indicates.
- the contact piece 3 is located in the region of the conductor receiving chamber 60.
- the conductor receiving chamber 60 can in particular be designed in the shape of a funnel.
- the contact piece 3 has electrically conductive contact pins 4 for electrical external contacting of the conductor connection terminal 1, which protrude from the insulating material housing 2.
- the contact piece 3 can be designed, for example, as a U-shaped component when looking into the conductor connection opening 6 , which extends from a lower section identified by the reference number 3 via a connecting section 33 to an upper section 32 .
- the upper section 32 is connected to a slanted section 31 of the contact piece 3 which is directed in the conductor insertion direction and acts as a slanted conductor insertion point.
- the beveled section 31 can also be formed as part of the housing 2 of the conductor connection terminal 1 .
- the clamping spring 5 extends from a first end area 52 over several arcuate areas to a second end area 50.
- the second end area 50 forms a conductor clamping point 30 with a contact point of the contact piece 3, with which a connected electrical conductor can be connected between the second end area 50 and the Contact piece 3 can be clamped, in particular the figure 2 indicates.
- the clamping spring 5 is deflected accordingly.
- the clamping spring 5 also has a driver element 51 .
- This can at integral formation of the clamping spring 5 can be produced by stamping out an inner portion of the material of the clamping spring. The punched-out inner section then forms the second end region 50 of the clamping spring 5.
- a crossbar at the end of the window-like recess 59 for example, lies against the pull arm 73 of the actuating lever 7 and forms the driver element 51.
- the clamping spring 5 is received and held within a clamping spring receiving area of the insulating material housing 2, which is bordered by an inner wall 23 of the insulating material housing 2.
- the clamping spring 5 is supported with its first end area 52 on one end of the upper section 32 of the contact piece 3 from below.
- the clamping spring 5 is supported with its second end section 50 on the lower section of the contact piece 3 or on the connected electrical conductor 8, 80.
- the actuating lever 7 has a grip area 70 which is designed for manually actuating the actuating lever 7 .
- the actuating lever 7 In the closed position, the actuating lever 7 is pivoted downwards and protrudes only slightly from the insulating material housing 2, in particular only in the handle area 70.
- the actuating lever 7 In the partially open position and in the fully open position, the actuating lever 7 is pivoted upwards and projects upwards out of the insulating material housing 2 .
- the actuating lever 7 has two bearing pins 71 protruding laterally from the material of the lever 7 .
- the actuating lever 7 is not mounted in the insulating material housing 2 via the bearing journals 71 .
- the bearing journals 71 serve to prevent the actuating lever 7, which is floating in the insulating material housing 1 and is therefore mounted loosely, from being lost can go. This will be discussed in more detail later in connection with the assembly of the operating lever 7 in the insulating material housing 2 .
- the floating mounting of the actuating lever 7 is realized by supporting the actuating lever 7 via an outer contour 72 of the actuating lever 7 forming a support surface, via which the actuating lever 7 is supported relative to the contact piece 3, in particular its upper section 32.
- the actuating lever 7 has a pull arm 73 embodied, for example, in the form of a protruding lug, which engages in the window recess 59 of the clamping spring 5 and thereby engages the driver element 51 from behind. Furthermore, the actuating lever 7 has a second lever latching means 74, embodied, for example, in the form of a protruding lug, via which the actuating lever 7 can be moved in its in figure 1 shown closed position by locking the second lever locking means 74 with a designed as a housing locking means, correspondingly shaped locking section on an inner wall 22 of the insulating housing 2 and can be fixed.
- the actuating lever 7 has a first lever latching means 75 embodied, for example, in the form of an indentation or a groove.
- the actuating lever 7 can be fixed in its fully open position via this first lever locking means 75, specifically by locking the first lever locking means 75 with a part of the contact piece 3 serving as a counter bearing, as in particular in FIG figure 4 is recognizable.
- the first lever latching means 75 latches onto an edge, for example the front edge 32a or the possibly rounded front edge at the front end of the upper section 32 of the contact piece 3 .
- This is in the figure 4 shown as detent R1.
- An additional detent R2 can be formed between a lower region of the pull arm 73 and a shoulder arranged, for example, on the inner housing wall 22 of the insulating material housing 2 .
- the outer contour 72 of the actuating lever 7 slides on the contact piece 3.
- the outer contour 72 is designed in such a way that the actuating lever 7 moves relative to the insulating material housing 2 and thus also to the contact piece 3 during the pivoting movement. This can be observed, for example, by an upward movement of the bearing pin 71 during the opening movement or a downward movement during the closing movement of the actuating lever 7.
- the actuating lever 7 is not supported on the surrounding insulating material housing 2 via the bearing journal 71, but rather via its rear outer contour 72, which is supported against the upper section 32 of the contact piece 3, which thus forms a pivot bearing surface.
- the lever 7 can also be supported with a rear side 79 on an inner wall 21 of the insulating material housing 2, at least in certain pivoting angles.
- the clamping spring 5 holds as a result of the tensile force exerted on the driver element 51 the actuating lever 7 in the position shown, the fixation being supported by the force of the clamping spring 5 via the first lever locking means 75 in connection with the first contact piece locking means.
- the clamping spring 5 With the operating lever 7 in the closed position and the electrical conductor 8 connected, as in figure 2 shown, the clamping spring 5 is deflected. In this state, the driver element 51 of the clamping spring 5 is therefore not in contact with the tension arm 73 of the actuating lever 7 and is located in a free space below the actuating lever 7. In this state, the actuating lever 7 is in connection with the second housing latching means by the second lever latching means 74 fixed in the position shown in the insulating material housing.
- the actuating lever 7 and its support on the contact piece 3 are provided at a point which is arranged away from the contact point of the contact piece 3 or the conductor clamping point 30, such that the conductor receiving chamber 60 is arranged in between.
- the actuating lever 7 is supported on a bearing section 3.2 of the contact piece 3, specifically on a second side 3.2b (top side here) of the bearing section 3.2 that faces away from the conductor receiving chamber 60.
- the contact leg 52 of the clamping spring 5 is supported on the opposite side of the contact piece 3, namely on a first side 3.2a (here underside) of the bearing section 3.2 facing the conductor receiving chamber 60.
- the figure 5 shows the actuating lever as a single component in an isometric representation.
- the bearing journals 71 can be flattened on the underside. This can be helpful for inserting the actuating lever 7 into the insulating housing 2, which is already closed. The actuating lever 7 can then also be inserted from above into the insulating material housing 2 in a position which corresponds to the fully open position. At the same time, the actuating lever 7 cannot be removed from the insulating housing 2 in the closed position.
- a correspondingly designed lever insertion channel 20 is provided with a guide contour 24, the clear width of which is smaller than the largest diameter of the bearing pin 71 and slightly larger than or equal to the diameter in the area of the flattening.
- the figure 6 shows the advantageous possibility of inserting the actuating lever 7 through the lever insertion channel 20 in the insulating material 2, from which in the figure 6 only part of the upper area is shown.
- the bearing pin is guided through the tapering lever insertion channel 20 in such a way that the bearing pin 71 snaps behind the inner wall of the housing when it enters the interior of the insulating material housing.
- actuating lever 7 can have recesses 76 and webs 77 .
- the insulating material housing 2 is already closed and the contact piece and the clamping spring are already inserted therein.
- the clamping spring can be pre-deflected by an object inserted into the conductor insertion opening 6 into the conductor receiving area 60 as an aid, e.g. a screwdriver or an electrical conductor, so that the driver element 51 as in figure 2 recognizable counterclockwise pivoted.
- the actuating lever 7 can then be used from above. In doing so, the pulling arm 73 grips behind the driver element 51, which has been pivoted by the aid.
- latching means 78 arranged on the side, e.g.
- FIGS Figures 7 to 9 shown in comparable views and positions as the first embodiments in the figures 1 , 2 and 4 , ie in the figure 7 in the closed position with no conductor connected, in which figure 8 in the closed position with the conductor connected and in the figure 9 in fully open position with no conductor connected.
- the second embodiment has many of the same features as the first embodiment and differs, among other things, in a different way of fixing the actuating lever 7 in the closed position.
- second lever locking means 74 is provided on this for fixing the actuating lever 7, but which is not spaced from the pull arm 73 as in the first embodiment, but is formed on this pull arm 73 itself.
- a web 26 is provided in the insulating material housing 2, which can be designed, for example, in the manner of a flexible housing strap. This web 26, which then forms the second housing locking means, can thus be deflected when the force is not applied too high, so that when the operating lever 7 is opened, the fixed, closed position can be overcome with moderate effort.
- the figure 7 shows the actuating lever 7 in the closed position.
- the second lever locking means 74 presses harder against the web 26 and deflects it somewhat. From a certain open position, the second lever locking means 74 snaps over the web 26, so that the fixation is overcome.
- the operating lever 7 can then be moved to the open position according to FIG figure 9 be led. In this it is fixed as in the first embodiment via a latch between the first lever latch means 75 and the contact piece 3 (latch R1).
- the other side wall can, as can be seen in the figures, be designed partially open.
- an open side wall of a conductor terminal is covered by the closed side wall 27 of the next conductor terminal.
- a cover plate 9 can be placed on this last conductor terminal, like that figure 13 indicates.
- the end plate 9 and the side wall 27 of a conductor terminal can each have a guide section 28, 98 at the upper edge, which serves to guide and hold the actuating lever 7 of an adjacent conductor terminal.
- the actuating lever 7 is supported with a guide contour (79a) facing the guide section 28, 98 on the guide section 28, 98 at least in sections during its pivoting movement.
- the Figures 13 and 14 show the conductor terminal according to the second embodiment in a cross-sectional view.
- the figure 13 represents the conductor connection terminal when the operating lever is in the closed position and the electrical conductor is inserted figure 14 with the actuating lever open and the electrical conductor also inserted.
- the Figures 15 to 17 show a third embodiment of the conductor terminal, each in a perspective view.
- the figure 18 shows the operating lever 7 of this conductor terminal, also in a perspective view.
- the actuating lever 7 is in the closed position.
- Both figures 16 and 17 an additional electrical conductor is inserted into the conductor connection terminal.
- the representation of figure 17 corresponds to that of figure 16 , with the difference that the contact piece 3 is shown cut in two places, in such a way that the connecting section 33 is missing. This further clarifies the view of the stripped end 80 of the conductor 8 and its clamping via the second end region 50 of the clamping spring 5 .
- a difference of the third embodiment of the conductor terminal to the previously described embodiments consists in the position and shape of an element 78a arranged on the lever 7 for fixing the lever in the closed position.
- the element 78a can again be regarded as a latching means, but differs from the previously explained lever-fixed latching means 74 in that the lever fixation realized in this way does not lead to a brief increase in the actuating force when the lever 7 is opened.
- the element 78a can be in the form of a web, for example, which is arranged on the side of the lever 7 and runs in a clearance in the adjacent housing 2 and in this way defines/limits an end position of the actuating lever 7 in each case.
- the actuating lever 7 is fixed relative to the insulating material housing 2 by means of lateral latching means 78 arranged in the front area of the actuating lever 7.
- the conductor connection terminal according to the invention in all of the explained embodiments additionally has an optimized overload protection for protecting the clamping spring 5 if the conductor 8 is inserted into the conductor receiving chamber 60 at an angle or otherwise improperly.
- the clamping spring 5 must be protected against excessive loading of the second end area 50 and the area that extends from the second end area 50 to the approximately semi-circular spring arc running along the wall 23 .
- the beveled section 31 designed as part of the insulating material housing 2 extends in the exemplary embodiment to below the upper section 32 of the contact piece. This beveled section 31 thus acts at the same time as a stop for the second end area 50 of the clamping spring 5, so that it cannot be deflected any further upwards.
- the part of the contact piece 3 on which the actuating lever 7 is supported at least in the open position and possibly also in other positions, in particular in positions before the open position is reached, can be considered in the direction of rotation of the actuating lever when opening can be designed as a rising ramp, falling ramp or as a neutral surface without an incline.
- the previously described first and third embodiment of the connection terminal show a design as a rising ramp, the second embodiment as a neutral surface.
- a falling ramp can be realized by the upper portion 32 of the contact piece 3 not, as for example in figure 1 can be seen, is formed to the operating lever 7 towards the front of the terminal 1, ie to the side of the conductor insertion opening 6, increasing, but with a decreasing pitch. With such a design, the actuating forces required to be applied to the actuating lever 7 for pivoting into the open position can be reduced. The result is an easier and more pleasant operation of the connection terminal.

Description
Die Erfindung betrifft eine Leiteranschlussklemme mit den Merkmalen des Anspruchs 1.The invention relates to a conductor terminal with the features of
Allgemein betrifft die Erfindung das Gebiet der elektrischen Leiteranschlusstechnik. Leiteranschlussklemmen, z.B. in Form von Reihenklemmen, sind z.B. aus der
Der Erfindung liegt die Aufgabe zugrunde, solche Leiteranschlussklemmen im Hinblick auf die Ergonomie, die Herstellungskosten und/oder die Montagefreundlichkeit weiterzuentwickeln.The invention is based on the object of further developing such conductor connection terminals with regard to ergonomics, manufacturing costs and/or ease of assembly.
Diese Aufgabe wird durch eine Leiteranschlussklemme gemäß Anspruch 1 gelöst.This object is achieved by a conductor terminal according to
In Folge der schwimmenden Lagerung passt sich der Betätigungshebel selbständig den auftretenden Kräfteverhältnissen an und unterliegt damit einem verringerten Verschleiß, verglichen mit einer festen Achslagerung. Zudem erlaubt die schwimmende Lagerung eine einfache, auch nachträgliche Montage des Betätigungshebels bei bereits geschlossenem Isolierstoffgehäuse. Die Abstützung des Betätigungshebels an dem Kontaktstück, das üblicherweise aus Metall gefertigt ist, bietet ein robustes Gegenlager für den Betätigungshebel. Dementsprechend bildet das Kontaktstück zusammen mit einem entsprechenden Teil des Betätigungshebels ein Schwenklager, das sehr verschleißarm ist. Da der Betätigungshebel vorteilhaft aus Kunststoff, z.B. einem Isolierstoffmaterial des Isolierstoffgehäuses, gefertigt sein kann, ergibt sich zudem mit dem metallischen Kontaktstück eine günstige Materialpaarung, die reibungsarm und zugleich verschleißarm ist.As a result of the floating bearing, the actuating lever automatically adapts to the forces that occur and is therefore subject to reduced wear compared to a fixed axle bearing. In addition, the floating mounting allows for simple, even subsequent assembly of the actuating lever when the insulating housing is already closed. The support of the operating lever on the contact piece, which is usually made of metal, offers a robust counter bearing for the operating lever. Accordingly, the contact piece, together with a corresponding part of the actuating lever, forms a pivot bearing that is very low-wear. Since the actuating lever can advantageously be made of plastic, for example an insulating material of the insulating housing, this also results with the metallic contact piece a favorable pairing of materials that is low-friction and at the same time low-wear.
Zusätzlich kann der Betätigungshebel, zumindest in bestimmten Verschwenkwinkeln, auch noch mit seiner Rückseite an einer Innenwand des Isolierstoffgehäuses abgestützt sein.In addition, the actuating lever, at least in certain pivoting angles, can also be supported with its rear side on an inner wall of the insulating material housing.
Der Betätigungshebel kann die Klemmfeder direkt oder indirekt beaufschlagen, um die Klemmwirkung der Klemmfeder an der Leiterklemmstelle aufzuheben und einen in die Leiteranschlussklemme eingeführten elektrischen Leiter nicht mit der Federkraft der Klemmfeder zu beaufschlagen, bzw. die Klemmstelle zu öffnen.The actuating lever can act on the clamping spring directly or indirectly in order to cancel the clamping effect of the clamping spring at the conductor clamping point and not to apply the spring force of the clamping spring to an electrical conductor inserted into the conductor connection terminal, or to open the clamping point.
Die Klemmfeder kann dabei den elektrischen Leiter an der Leiterklemmstelle direkt mit der Federkraft beaufschlagen, indem die Klemmfeder den Leiter berührt, oder indirekt über ein Zwischenbauteil.The clamping spring can apply the spring force directly to the electrical conductor at the conductor clamping point, in that the clamping spring touches the conductor, or indirectly via an intermediate component.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Kontaktstück einen Klemmabschnitt, in dem die Kontaktstelle angeordnet ist, und einen Lagerabschnitt aufweist, an dem der Betätigungshebel in der geöffneten Stellung wenigstens zum Teil abgestützt ist, wobei die Leiteraufnahmekammer zwischen dem Klemmabschnitt und dem Lagerabschnitt angeordnet ist. Dies hat den Vorteil, dass eine Entflechtung der Bereiche Lagerabschnitt und Klemmabschnitt durch den dazwischenliegenden Bereich der Leiteraufnahmekammer erreicht wird. Auf diese Weise werden günstigere Konstruktions- und Platzbedingungen der Leiteranschlussklemme geschaffen.According to an advantageous development of the invention, it is provided that the contact piece has a clamping section, in which the contact point is arranged, and a bearing section, on which the actuating lever is at least partially supported in the open position, with the conductor receiving chamber between the clamping section and the bearing section is arranged. This has the advantage that the areas of the bearing section and the clamping section are separated by the area of the conductor receiving chamber lying in between. In this way, more favorable construction and space conditions of the conductor terminal are created.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Klemmfeder einen Anlageschenkel aufweist, über den die Klemmfeder an einer der Leiteraufnahmekammer zugewandten ersten Seite des Lagerabschnitts am Kontaktstück abgestützt ist. Dies hat den Vorteil, dass die Klemmfeder bei geringen Material- und Produktionskosten sicher abgestützt ist.According to an advantageous development of the invention, it is provided that the clamping spring has a contact leg, via which the clamping spring is supported on a first side of the bearing section, which faces the conductor receiving chamber, on the contact piece. This has the advantage that the clamping spring is securely supported with low material and production costs.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Betätigungshebel zumindest in der geöffneten Stellung wenigstens zum Teil an einer der Leiteraufnahmekammer abgewandten zweiten Seite des Lagerabschnitts des Kontaktstücks abgestützt ist. Dies hat den Vorteil, dass der Betätigungshebel bei geringen Material- und Produktionskosten sicher abgestützt ist.According to an advantageous development of the invention, it is provided that the actuating lever, at least in the open position, is at least partially supported on a second side of the bearing section of the contact piece, facing away from the conductor receiving chamber. This has the advantage that the operating lever is securely supported with low material and production costs.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Lagerabschnitt mit dem Klemmabschnitt über einen Verbindungsabschnitt des Kontaktstücks verbunden ist. Auf diese Weise kann das Kontaktstück mit dem Lagerabschnitt und dem Klemmabschnitt auf einfache Weise als einstückiges Bauteil bereitgestellt werden, z.B. in Form eines Stanzbiegeteils. Vorteilhaft kann dabei der Verbindungsabschnitt seitlich an dem Bereich vorbeigeführt werden, in dem der Leiter in der Leiteraufnahmekammer aufgenommen werden soll. Auf diese Weise kann der Verbindungsabschnitt zugleich eine seitliche Begrenzung der Leiteraufnahmekammer bilden. So kann die Anordnung aus Lagerabschnitt, Verbindungsabschnitt und Klemmabschnitt z.B. in einer U-Form ausgebildet sein. Insbesondere können der Klemmabschnitt, der Lagerabschnitt und der Verbindungsabschnitt aus einem Material, insbesondere Metall, einstückig ausgeformt sein.According to an advantageous development of the invention, it is provided that the bearing section is connected to the clamping section via a connecting section of the contact piece. In this way, the contact piece with the bearing section and the clamping section can be provided in a simple manner as a one-piece component, e.g. in the form of a stamped and bent part. Advantageously, the connecting section can be guided laterally past the area in which the conductor is to be accommodated in the conductor receiving chamber. In this way, the connecting section can also form a lateral delimitation of the conductor receiving chamber. For example, the arrangement of bearing section, connecting section and clamping section can be formed in a U-shape. In particular, the clamping section, the bearing section and the connecting section can be formed in one piece from a material, in particular metal.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Lagerabschnitt des Kontaktstücks als Platte ausgebildet ist, insbesondere als metallische Platte. Insbesondere können die erste Seite des Lagerabschnitts und die zweite Seite des Lagerabschnitts durch die Dicke der Platte des Lagerabschnitts voneinander beabstandet sein.According to an advantageous development of the invention, it is provided that the bearing section of the contact piece is designed as a plate, in particular as a metal plate. In particular, the first side of the bearing section and the second side of the bearing section can be spaced apart from one another by the thickness of the plate of the bearing section.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass zumindest in der geöffneten Stellung des Betätigungshebels eine geschlossene Kraftkette gebildet ist von einem Mitnehmerelement der Klemmfeder über einen das Mitnehmerelement beaufschlagenden Zugarm des Betätigungshebels, über dessen Außenkontur, und über die erste Seite und die zweite Seite des Lagerabschnitts auf den Anlageschenkel der Klemmfeder. Dies erlaubt eine kinematisch günstige Kraftführung bei zugleich geringer Kraftbelastung der Isolierstoffgehäuse-Teile. Durch eine solche geschlossene Kraftkette, die dadurch gekennzeichnet ist, dass die Kraftvektorsumme den Wert Null ergibt, werden die durch die geöffnete Stellung des Betätigungshebels ausgeübten Kräfte besonders effizient auf den Anlageschenkel der Klemmfeder übertragen.According to an advantageous development of the invention, it is provided that at least in the open position of the actuating lever a closed force chain is formed by a driver element of the clamping spring via a tension arm of the actuating lever acting on the driver element its outer contour, and via the first side and the second side of the bearing section onto the contact leg of the clamping spring. This allows a kinematically favorable force guidance with at the same time low force loading of the insulating material housing parts. With such a closed force chain, which is characterized in that the sum of the force vectors is zero, the forces exerted by the open position of the actuating lever are transmitted particularly efficiently to the contact leg of the clamping spring.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Leiteraufnahmekammer durch den oberen Abschnitt, insbesondere den Lagerabschnitt, des Kontaktstücks von dem Betätigungshebel getrennt ist. Dies hat den Vorteil, dass eine Entflechtung der Bereiche Lagerabschnitt und Klemmabschnitt durch den dazwischenliegenden Bereich der Leiteraufnahmekammer erreicht wird. Auf diese Weise werden günstigere Konstruktions- und Platzbedingungen der Leiteranschlussklemme geschaffen.According to an advantageous development of the invention, it is provided that the conductor receiving chamber is separated from the actuating lever by the upper section, in particular the bearing section, of the contact piece. This has the advantage that the areas of the bearing section and the clamping section are separated by the area of the conductor receiving chamber lying in between. In this way, more favorable construction and space conditions of the conductor terminal are created.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist ein Zugarm des Betätigungshebels zwischen der Außenkontur des Betätigungshebels und einem Griffbereich des Betätigungshebels angeordnet. Dies hat den Vorteil, dass trotz kompakter Außenabmessungen der Leiteranschlussklemme ein großer Hebelarm am Betätigungshebel realisiert werden kann.According to an advantageous development of the invention, a pull arm of the actuating lever is arranged between the outer contour of the actuating lever and a grip area of the actuating lever. This has the advantage that, despite the compact external dimensions of the conductor connection terminal, a large lever arm can be implemented on the actuating lever.
Gemäß einer vorteilhaften Weiterbildung der Erfindung weist der Betätigungshebel eine Exzenter-Außenkontur auf, über die der Betätigungshebel an dem Kontaktstück abgestützt ist. Die Schwenklagerkontur des Betätigungshebels wird somit durch die Exzenter-Außenkontur gebildet. Dies hat den Vorteil, dass der Betätigungshebel bei geringen manuellen Betätigungskräften relativ große Kräfte zum Betätigen der Klemmfeder ausüben kann (große Kraftübersetzung), was mit einer angenehm leichtgängigen Bedienung der Leiteranschlussklemme einhergeht.According to an advantageous development of the invention, the actuating lever has an eccentric outer contour, via which the actuating lever is supported on the contact piece. The pivot bearing contour of the actuating lever is thus formed by the eccentric outer contour. This has the advantage that the actuating lever can exert relatively large forces to actuate the clamping spring with low manual actuating forces (large force transmission), which is associated with a pleasantly smooth operation of the conductor terminal.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist der Betätigungshebel bei einem Verschwenken zusätzlich zu einer rotatorischen Bewegung translatorisch relativ zum Isolierstoffgehäuse und/oder dem Kontaktstück verlagerbar. Hierdurch hat der Betätigungshebel verbesserte Freiheitsgrade bei der Verschwenkbewegung, was wiederum förderlich ist für eine verschleißarme Lagerung, eine einfache Montierbarkeit des Betätigungshebels im Isolierstoffgehäuse der Leiteranschlussklemme und eine angenehme Haptik bei der Betätigung.According to an advantageous development of the invention, the actuating lever can be displaced translationally relative to the insulating material housing and/or the contact piece when it is pivoted in addition to a rotary movement. As a result, the actuating lever has improved degrees of freedom during the pivoting movement, which in turn is conducive to low-wear storage, easy assembly of the actuating lever in the insulating material housing of the conductor terminal and a pleasant feel during actuation.
Gemäß einer vorteilhaften Weiterbildung der Erfindung weist der Betätigungshebel wenigstens einen Zugarm auf, der ein Mitnehmerelement der Klemmfeder hintergreift, so dass die Klemmfeder bei einem Verschwenken des Betätigungshebels in die geöffnete Stellung durch den Zugarm durch Zugbelastung der Klemmfeder auslenkbar ist. Dies hat den Vorteil, dass die Klemmfeder zugleich eine Reaktionskraft auf den Betätigungshebel ausüben kann, der diesen in Richtung der geschlossenen Stellung beaufschlagt. Zudem kann auf diese Weise mit wenig Aufwand ein selbstverriegelndes Kniehebelprinzip bezüglich des Betätigungshebels realisiert werden, so dass für dessen Arretierung in der geöffneten Stellung kein oder nur wenig zusätzlicher Aufwand erforderlich ist.According to an advantageous development of the invention, the actuating lever has at least one tension arm which engages behind a driver element of the clamping spring, so that the clamping spring can be deflected by the tension arm when the actuating lever is pivoted into the open position by tensile loading of the clamping spring. This has the advantage that the clamping spring can simultaneously exert a reaction force on the actuating lever, which acts on it in the direction of the closed position. In addition, a self-locking toggle lever principle can be implemented with little effort in this way with regard to the actuating lever, so that little or no additional effort is required to lock it in the open position.
Gemäß einer vorteilhaften Weiterbildung der Erfindung weist die Klemmfeder eine fensterartige Ausnehmung auf, in die der Zugarm des Betätigungshebels eingreift. Auf diese Weise kann das Mitnehmerelement der Klemmfeder durch einen oberen Rand der fensterartigen Ausnehmung, oder mit anderen Worten einem dort gebildeten Quersteg der Klemmfeder, realisiert werden. Dies erlaubt eine Ankopplung der Klemmfeder an den Zugarm auf einfache und kostengünstige Weise. Es ist lediglich die fensterartige Ausnehmung durch Austanzen eines Materialstücks aus dem Material der Klemmfeder herzustellen. Zudem kann auf diese Weise ein sich selbst verkoppelndes System geschaffen werden, bei dem der Betätigungshebel bei bereits im Isolierstoffgehäuse eingesetzter Klemmfeder in das Isolierstoffgehäuse eingesetzt werden kann und der Zugarm dann in die fensterartige Ausnehmung einschnappen kann. Hiernach hintergreift der Zugarm das Mitnehmerelement, so dass fortan eine Betätigung der Klemmfeder durch Verschwenken des Betätigungshebels möglich ist.According to an advantageous development of the invention, the clamping spring has a window-like recess into which the pull arm of the actuating lever engages. In this way, the driver element of the clamping spring can be realized by an upper edge of the window-like recess, or in other words a transverse web of the clamping spring formed there. This allows the clamping spring to be coupled to the tension arm in a simple and inexpensive manner. It is only necessary to produce the window-like recess by punching out a piece of material from the material of the clamping spring. In addition, a self-coupling system can be created in this way, in which the actuating lever can be inserted into the insulating material housing with the clamping spring already inserted in the insulating material housing and the pull arm can then be inserted into the window-like recess can snap. After this, the pulling arm engages behind the driver element, so that from now on the clamping spring can be actuated by pivoting the actuating lever.
Gemäß der Erfindung weist die Leiteranschlussklemme erste Rastmittel auf, durch die der Betätigungshebel in der geöffneten Stellung verrastet ist. Dies hat den Vorteil, dass der Betätigungshebel in der geöffneten Stellung in einer definierten Position verbleibt, ohne dass er von einem Benutzer festgehalten werden muss. Dies erlaubt eine praktische und ergonomische Handhabung der Leiteranschlussklemme und führt insbesondere bei einer Vielzahl von Leiteranschlussklemmen, z.B. einer Reihenklemmenanordnung, zu einer vereinfachten Handhabung.According to the invention, the conductor connection terminal has first latching means, by which the actuating lever is latched in the open position. This has the advantage that the actuating lever remains in the open position in a defined position without the user having to hold it. This allows practical and ergonomic handling of the conductor connection terminal and leads to simplified handling, particularly when there are a large number of conductor connection terminals, e.g. a terminal block arrangement.
Gemäß der Erfindung weisen die ersten Rastmittel ein erstes Hebelrastmittel auf, das Teil des Betätigungshebels ist, und ein erstes Kontaktstückrastmittel, das Teil des Kontaktstücks ist. Das erste Hebelrastmittel und das erste Kontaktstückrastmittel wirken miteinander zur Verrastung des Betätigungshebels in der geöffneten Stellung zusammen. So kann z.B. das erste Hebelrastmittel als Nut, Mulde oder sonstige Vertiefung im Betätigungshebel ausgebildet sein, und das erste Kontaktstückrastmittel als hinsichtlich der Formgebung an das erste Hebelrastmittel angepasste hervorstehende Nase, Anlagekante oder als ähnlicher Vorsprung. Auch eine umgekehrte Zuordnung ist vorteilhaft, indem das erste Hebelrastmittel als Nase oder sonstiger Vorsprung und das erste Kontaktstückrastmittel als Nut oder sonstige Vertiefung ausgebildet ist. Insbesondere kann das erste Kontaktstückrastmittel durch den vorderen Rand oder eine abgerundete Stirnkante am vorderen Ende eines zum Betätigungshebel weisenden oberen Abschnitts des Kontaktstücks gebildet sein.According to the invention, the first latching means comprises a first lever latching means which is part of the operating lever and a first contact piece latching means which is part of the contact piece. The first lever latching means and the first contact piece latching means cooperate with each other to latch the actuating lever in the open position. For example, the first lever locking means can be designed as a groove, trough or other depression in the actuating lever, and the first contact piece locking means can be designed as a protruding nose, contact edge or similar projection adapted to the shape of the first lever locking means. A reverse assignment is also advantageous, in that the first lever locking means is in the form of a nose or other projection and the first contact piece locking means is in the form of a groove or other indentation. In particular, the first contact piece latching means can be formed by the front edge or a rounded front edge at the front end of an upper section of the contact piece pointing toward the actuating lever.
Gemäß einer vorteilhaften Weiterbildung der Erfindung weist die Leiteranschlussklemme zweite Rastmittel auf, durch die der Betätigungshebel in der geschlossenen Stellung verrastet ist. Dies hat den Vorteil, dass der Betätigungshebel auf definierter Weise in der geschlossenen Stellung gehalten werden kann und sich nicht unbeabsichtigt öffnet.According to an advantageous development of the invention, the conductor connection terminal has second latching means, by means of which the actuating lever is latched in the closed position. This has the advantage that the operating lever can be held in the closed position in a defined manner and does not open unintentionally.
Gemäß einer vorteilhaften Weiterbildung der Erfindung weisen die zweiten Rastmittel ein zweites Hebelrastmittel, das Teil der Betätigungshebels ist, und ein zweites Gehäuserastmittel, das Teil des Isolierstoffgehäuses ist, auf. Das zweite Hebelrastmittel und das zweite Gehäuserastmittel wirken miteinander zur Verrastung des Betätigungshebels in der geschlossenen Stellung zusammen.According to an advantageous development of the invention, the second latching means have a second lever latching means, which is part of the actuating lever, and a second housing latching means, which is part of the insulating housing. The second lever latch means and the second housing latch means cooperate with each other to latch the operating lever in the closed position.
Gemäß einer vorteilhaften Weiterbildung der Erfindung weist der Betätigungshebel parallel zur Drehachse der Verschwenkbewegung abstehende Lagerzapfen auf, die zur Sicherung des Betätigungshebels gegen ein Entfernen des Betätigungshebels aus dem Isolierstoffgehäuse ausgebildet sind. Auf diese Weise kann der schwimmend gelagerte Betätigungshebel in Betriebssituationen der Leiteranschlussklemme, in denen der Betätigungshebel nicht anderweitig, z.B. durch die Klemmfeder, in dem Isolierstoffgehäuse gehalten wird, gesichert werden. Hierbei fungieren die Lagerzapfen nicht, oder zumindest nicht in erster Linie, zur Lagerung des Betätigungshebels im Isolierstoffgehäuse zur Durchführung der Verschwenkbewegung, sondern hauptsächlich als Sicherungsmittel gegen ein Entfernen des Betätigungshebels aus dem Isolierstoffgehäuse.According to an advantageous further development of the invention, the actuating lever has bearing pins which protrude parallel to the axis of rotation of the pivoting movement and which are designed to secure the actuating lever against removal of the actuating lever from the insulating material housing. In this way, the floating operating lever can be secured in operating situations of the conductor connection terminal in which the operating lever is not otherwise held in the insulating housing, e.g. by the clamping spring. In this case, the bearing journals do not function, or at least not primarily, for mounting the actuating lever in the insulating material housing for carrying out the pivoting movement, but mainly as a means of securing against removal of the actuating lever from the insulating material housing.
Gemäß einer vorteilhaften Weiterbildung der Erfindung weist das Isolierstoffgehäuse einen Hebeleinführkanal zum Einsetzen des Betätigungshebels auf, wobei der Hebeleinführkanal eine Führungskontur zur Führung der Lagerzapfen zumindest während des Einsetzens des Betätigungshebels aufweist. Auf diese Weise haben die Lagerzapfen neben der Sicherung gegen ein Entfernen des Betätigungshebels eine weitere Funktion, nämlich eine Führungsfunktion des Betätigungshebels während des Einsetzens in das Isolierstoffgehäuse. Durch die Führung der Lagerzapfen entlang der Führungskontur im Hebeleinführkanal legen die in dem Isolierstoffgehäuse anzuordnenden Bereiche des Betätigungshebels einen definierten Pfad darin zurück, der durch Gestaltung der Führungskontur so ausgebildet ist, dass der Hebel an seine gewünschte Endposition im Isolierstoffgehäuse gelangt und dabei nicht durch andere Bauteile, wie etwa die Klemmfeder, am Einführen gehindert wird. Zudem wird sichergestellt, dass der Zugarm des Betätigungshebels letztendlich das Mitnehmerelement der Klemmfeder hintergreift, so dass der Betätigungshebel seine Funktion zum Betätigen der Klemmfeder ausüben kann.According to an advantageous development of the invention, the insulating material housing has a lever insertion channel for inserting the actuating lever, the lever insertion channel having a guide contour for guiding the bearing journal at least during insertion of the actuating lever. In this way, in addition to securing the actuating lever against removal, the bearing journals have another function, namely a guiding function of the actuating lever during insertion into the insulating material housing. Due to the guidance of the bearing journals along the guide contour in the lever insertion channel, the areas of the actuating lever to be arranged in the insulating-material housing place one defined path in it, which is formed by designing the guide contour in such a way that the lever reaches its desired end position in the insulating material housing and is not prevented from being inserted by other components, such as the clamping spring. In addition, it is ensured that the pulling arm of the actuating lever ultimately engages behind the driver element of the clamping spring, so that the actuating lever can perform its function of actuating the clamping spring.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist der Teil des Kontaktstücks, an dem der Betätigungshebel zumindest in der geöffneten Stellung abgestützt ist, als in Rotationsrichtung des Betätigungshebels beim Öffnen abfallende Rampe ausgebildet. Hierdurch können die erforderlichen Betätigungskräfte, die am Betätigungshebel für das Verschwenken in die geöffnete Stellung aufzubringen sind, reduziert werden. Die Rampe kann als lineare Rampe oder nichtlineare Rampe ausgebildet sein, d.h. mit linear abfallender Kontur oder mit nichtlinear abfallender Kontur, z.B. progressiv oder degressiv abfallender Kontur.According to an advantageous development of the invention, the part of the contact piece on which the actuating lever is supported at least in the open position is designed as a ramp that falls in the direction of rotation of the actuating lever when it is opened. As a result, the required actuating forces that have to be applied to the actuating lever for pivoting into the open position can be reduced. The ramp can be in the form of a linear ramp or a non-linear ramp, i.e. with a linearly decreasing contour or with a non-linearly decreasing contour, e.g. a progressively or degressively decreasing contour.
Ein vorteilhaftes Verfahren zur Montage einer derartigen Leiteranschlussklemme weist die folgenden in der angegebenen Reihenfolge auszuführenden Schritte auf:
- a1) Bereitstellen des Isolierstoffgehäuses mit darin bereits angeordnetem Kontakteinsatz,
- b1) Einsetzen des Betätigungshebels zumindest mit seinem Schwenklagerbereich in das Isolierstoffgehäuse durch einen Hebeleinführkanal des Isolierstoffgehäuses.
- a1) providing the insulating material housing with the contact insert already arranged therein,
- b1) inserting the operating lever at least with its pivot bearing area into the insulating material housing through a lever insertion channel of the insulating material housing.
Dies hat den Vorteil einer einfachen und schnelle Montage der Leiteranschlussklemme. Als Montage der Leiteranschlussklemme wird hierbei der Zusammenbau der einzelnen Komponenten der Leiteranschlussklemme zur fertigen, letztendlich funktionsfähigen Leiteranschlussklemme verstanden.This has the advantage of easy and quick assembly of the conductor connection terminal. The assembly of the conductor terminal is understood to mean the assembly of the individual components of the conductor terminal to form the finished, ultimately functional conductor terminal.
Zum Bereitstellen des Isolierstoffgehäuses mit dem darin bereits angeordnetem Kontakteinsatz können die Gehäuseteile des Isolierstoffgehäuses, z.B. zwei Gehäuse-Halbschalen, vor dem Zusammensetzen mit den Bauteilen des Kontakteinsatzes bestückt werden und dann zusammengefügt werden.To provide the insulating material housing with the contact insert already arranged therein, the housing parts of the insulating material housing, e.g. two housing half-shells, can be equipped with the components of the contact insert before assembly and then joined together.
Das zuvor genannte Verfahren kann wie folgt vorteilhaft weitergebildet werden:
- a1) Bereitstellen des Isolierstoffgehäuses mit darin bereits angeordnetem Kontakteinsatz,
- a2) Auslenken der Klemmfeder durch Einsetzen eines Hilfsmittels, z.B. eines Kerns oder eines Leiters, in eine Leitereinführungsöffnung der Leiteranschlussklemme,
- b1) Einsetzen des Betätigungshebels zumindest mit seinem Schwenklagerbereich in das Isolierstoffgehäuse durch einen Hebeleinführkanal des Isolierstoffgehäuses
- b2) Entfernen des Hilfsmittels von der Leiteranschlussklemme.
- a1) providing the insulating material housing with the contact insert already arranged therein,
- a2) deflection of the clamping spring by inserting an aid, e.g. a core or a conductor, into a conductor insertion opening of the conductor connection terminal,
- b1) inserting the operating lever at least with its pivot bearing area into the insulating material housing through a lever insertion channel of the insulating material housing
- b2) Removing the tool from the conductor terminal.
Dies hat den Vorteil, dass der Betätigungshebel noch einfacher in das Isolierstoffgehäuse eingesetzt werden kann und dabei ein unerwünschter, zu früher Kontakt mit der Klemmfeder vermieden wird. Hierdurch kann ein unerwünschter Materialabrieb oder ein Zerkratzen des Betätigungshebels sowie die Gefahr von Materialabrieb an der Leiterklemmstelle minimiert werden.This has the advantage that the actuating lever can be inserted even more easily into the insulating material housing, and unwanted contact with the clamping spring that is too early is avoided. Undesirable material abrasion or scratching of the actuating lever and the risk of material abrasion at the conductor clamping point can be minimized as a result.

Die
Die Leiteranschlussklemme 1 weist ein Isolierstoffgehäuse 2 auf, das z.B. als flaches, im Wesentlichen quaderförmiges Gehäuse ausgebildet sein kann, so dass mehrere Leiteranschlussklemmen nebeneinander aneinanderreihbar sind. Das Isolierstoffgehäuse 2 kann beispielsweise in Form zweier Gehäusehalbschalen ausgebildet sein, die nach dem Einbau der inneren Bauteile miteinander verbunden werden. Vorteilhaft nimmt das Isolierstoffgehäuse 2 die inneren Bauteile auf, wobei die offene Seite abschließend mit einem Deckel 9 oder einer angrenzenden Leiteranschlussklemme 1 verschlossen wird. Dementsprechend zeigen die
Die Leiteranschlussklemme 1 weist als weitere Bauteile wenigstens ein Kontaktstück 3, eine Klemmfeder 5 und einen Betätigungshebel 7 auf. Das Kontaktstück 3 bildet mit der Klemmfeder 5 einen Kontakteinsatz der Leiteranschlussklemme 1. Die Klemmfeder 5 und das Kontaktstück 3 sind z.B. vollständig aus elektrisch leitfähigem Material gefertigt, insbesondere aus Metall. Der Betätigungshebel kann aus grundsätzlich beliebigen Materialien gefertigt sein, z.B. aus dem gleichen Material wie das Isolierstoffgehäuse 2, z.B. aus einem Kunststoffmaterial.The
Das Isolierstoffgehäuse 2 weist eine Leitereinführungsöffnung 6 auf, durch die ein anzuschließender elektrischer Leiter 8 in die Leiteranschlussklemme 1 eingeführt werden kann. Der Leiter 8 kann mit einem abisolierten Ende 80 voran durch die Leitereinführungsöffnung 6 bis in eine Leiteraufnahmekammer 60 geführt werden, wie die
Die Klemmfeder 5 erstreckt sich von einem ersten Endbereich 52 hin über mehrere bogenförmige Bereiche hin zu einem zweiten Endbereich 50. Der zweite Endbereich 50 bildet mit einer Kontaktstelle des Kontaktstücks 3 eine Leiterklemmstelle 30, mit der ein angeschlossener elektrischer Leiter zwischen dem zweiten Endbereich 50 und dem Kontaktstück 3 eingeklemmt werden kann, wie insbesondere die
Die Klemmfeder 5 weist ferner ein Mitnehmerelement 51 auf. Dieses kann bei einstückiger Ausbildung der Klemmfeder 5 durch Ausstanzen eines inneren Abschnitts des Materials der Klemmfeder hergestellt werden. Der ausgestanzte innere Abschnitt bildet dann den zweiten Endbereich 50 der Klemmfeder 5. Der das Mitnehmerelement 51 aufweisende Teil der Klemmfeder, der dann eine in den
Die Klemmfeder 5 ist innerhalb eines Klemmfederaufnahmebereichs des Isolierstoffgehäuses 2, der von einer Innenwand 23 des Isolierstoffgehäuses 2 umrandet ist, aufgenommen und darin gehalten. Die Klemmfeder 5 stützt sich mit ihrem ersten Endbereich 52 an einem Ende des oberen Abschnitts 32 des Kontaktstücks 3 von unten ab. Die Klemmfeder 5 stützt sich mit ihrem zweiten Endabschnitt 50 an dem unteren Abschnitt des Kontaktstücks 3 bzw. am angeschlossenen elektrischen Leiter 8, 80 ab.The clamping
Der Betätigungshebel 7 weist einen Griffbereich 70 auf, der zum manuellen Betätigen des Betätigungshebels 7 ausgebildet ist. In der geschlossenen Stellung ist der Betätigungshebel 7 nach unten verschwenkt und steht nur wenig, insbesondere nur in dem Griffbereich 70, von dem Isolierstoffgehäuse 2 hervor. In der teilweise geöffneten Stellung und in der vollständig geöffneten Stellung ist der Betätigungshebel 7 nach oben verschwenkt und steht nach oben aus dem Isolierstoffgehäuse 2 heraus.The
Ferner weist der Betätigungshebel 7 zwei seitlich aus dem Material des Hebels 7 herausstehende Lagerzapfen 71 auf. Der Betätigungshebel 7 ist aber nicht über die Lagerzapfen 71 in dem Isolierstoffgehäuse 2 gelagert. Vielmehr dienen die Lagerzapfen 71 dazu zu verhindern, dass der Betätigungshebel 7, der in dem Isolierstoffgehäuse 1 schwimmend und damit lose gelagert ist, daraus verloren gehen kann. Hierauf wird später noch im Zusammenhang mit der Montage des Betätigungshebels 7 im Isolierstoffgehäuse 2 näher eingegangen.Furthermore, the
Die schwimmende Lagerung des Betätigungshebels 7 wird durch eine Abstützung des Betätigungshebels 7 über eine eine Abstützfläche bildende Außenkontur 72 des Betätigungshebels 7 realisiert, über die der Betätigungshebel 7 sich gegenüber dem Kontaktstück 3, insbesondere dessen oberen Abschnitt 32, abstützt.The floating mounting of the
Der Betätigungshebel 7 weist einen z.B. in Form einer hervorstehenden Nase ausgebildeten Zugarm 73 auf, der in die Fensterausnehmung 59 der Klemmfeder 5 eingreift und dadurch das Mitnehmerelement 51 hintergreift. Ferner weist der Betätigungshebel 7 ein z.B. in Form einer hervorstehenden Nase ausgebildetes zweites Hebelrastmittel 74 auf, über das der Betätigungshebel 7 in seiner in
Ferner weist der Betätigungshebel 7 ein z.B. in Form einer Einbuchtung oder einer Nut ausgebildetes erstes Hebelrastmittel 75 auf. Über dieses erste Hebelrastmittel 75 kann der Betätigungshebel 7 in seiner vollständig geöffneten Stellung fixiert werden, und zwar durch Verrastung des ersten Hebelrastmittels 75 mit einem Teil des als Gegenlager dienendem Kontaktstücks 3, wie insbesondere in der
Bei einer Betätigung des Betätigungshebels 7 von der geschlossenen Stellung in die teilweise geöffnete oder vollständig geöffnete Stellung zieht dieser über den Zugarm 73 das Mitnehmerelement 51 der Klemmfeder 5 mit, d.h. das Mitnehmerelement 51 wird nach oben hin ausgelenkt. In Folge der Verbindung des Mitnehmerelements 51 mit dem zweiten Endabschnitt 50 im unteren Bereich der Klemmfeder 5 wird auch dieser Bereich mit nach oben bewegt, so dass der zweite Endabschnitt 50 von der Leiterklemmstelle 30 fortgezogen wird. Auf diese Weise kann ein elektrischer Leiter 8 aus der Leiteranschlussklemme 1 entfernt werden oder mit geringerem Aufwand eingesteckt werden. Insbesondere bei feindrähtigen Ausführungen des elektrischen Leiters wird hierdurch ein Einführen in die Leiteranschlussklemme 1 erst ermöglicht.When actuating the
Bei seiner Bewegung von der geschlossenen Stellung in die teilweise oder vollständig geöffnete Stellung oder bei der entsprechend umgekehrten Bewegung des Betätigungshebels 7 gleitet die Außenkontur 72 des Betätigungshebels 7 auf dem Kontaktstück 3 ab. Die Außenkontur 72 ist dabei so ausgebildet, dass sich der Betätigungshebel 7 während der Verschwenkbewegung relativ zum Isolierstoffgehäuse 2 und damit auch zum Kontaktstück 3 bewegt. Dies kann z.B. durch eine Aufwärtsbewegung der Lagerzapfen 71 bei der Öffnungsbewegung bzw. eine Abwärtsbewegung bei der Schließbewegung des Betätigungshebels 7 beobachtet werden.During its movement from the closed position to the partially or fully open position or during the corresponding reverse movement of the
Bei einer Verschwenkbewegung stützt sich der Betätigungshebel 7 somit zumindest in der Regel nicht über die Lagerzapfen 71 an dem umgebenden Isolierstoffgehäuse 2 ab, sondern über seine rückwärtige Außenkontur 72, die sich gegenüber dem oberen Abschnitt 32 des Kontaktstücks 3 abstützt, der damit eine Schwenklagerfläche bildet. Zusätzlich kann sich der Hebel 7, zumindest in bestimmten Verschwenkwinkeln, auch noch mit einer Rückseite 79 an einer Innenwand 21 des Isolierstoffgehäuses 2 abstützen.During a pivoting movement, the
In der vollständig geöffneten Stellung, wie in
Bei geschlossener Stellung des Betätigungshebels 7 und angeschlossenem elektrischen Leiter 8, wie in
Wie erkennbar ist, ist der Betätigungshebel 7 sowie seine Abstützung an dem Kontaktstück 3 an einer Stelle vorgesehen, die entfernt von der Kontaktstelle des Kontaktstücks 3 bzw. der Leiterklemmstelle 30 angeordnet, derart, dass dazwischen die Leiteraufnahmekammer 60 angeordnet ist. Hierbei ist der Betätigungshebel 7 an einem Lagerabschnitt 3.2 des Kontaktstücks 3 abgestützt, und zwar an einer der Leiteraufnahmekammer 60 abgewandten zweiten Seite 3.2b (hier Oberseite) des Lagerabschnitts 3.2. Der Anlageschenkel 52 der Klemmfeder 5 ist dagegen an der gegenüberliegenden Seite des Kontaktstücks 3 abgestützt, nämlich an einer der Leiteraufnahmekammer 60 zugewandten ersten Seite 3.2a (hier Unterseite) des Lagerabschnitts 3.2.As can be seen, the
Die
Erkennbar ist ferner, dass der Betätigungshebel 7 Aussparungen 76 und Stege 77 aufweisen kann.It can also be seen that the
Für die Montage des Betätigungshebels 7 im Isolierstoffgehäuse 2 kann es vorteilhaft sein, wenn das Isolierstoffgehäuse 2 bereits geschlossen ist und darin das Kontaktstück und die Klemmfeder bereits eingesetzt sind. Zur Unterstützung des Einsetzens des Betätigungshebels 7 kann die Klemmfeder durch einen in die Leitereinführungsöffnung 6 bis in den Leiteraufnahmebereich 60 als Hilfsmittel eingeschobenen Gegenstand, z.B. einen Schraubendreher oder einen elektrischen Leiter, vorausgelenkt werden, so dass das Mitnehmerelement 51 wie in
Zur Fixierung des Betätigungshebels 7 in der geschlossenen Stellung können zusätzlich seitlich angeordnete Rastmittel 78 vorhanden sein, z.B. links und rechts seitlich angeordnet, die den geschlossenem Betätigungshebel 7 durch vorstehende Gehäusekanten 25 des Isolierstoffgehäuses 2 fixieren.To fix the

Ein Unterschied der dritten Ausführungsform der Leiteranschlussklemme zu den zuvor beschriebenen Ausführungsformen besteht in der Lage und Formgebung eines am Hebel 7 angeordneten Elements 78a zur Hebelfixierung in der geschlossenen Stellung. Das Element 78a kann wiederum als Rastmittel angesehen werden, unterscheidet sich aber von den zuvor erläuterten hebelfesten Rastmitteln 74 dadurch, dass die auf diese Weise realisierte Hebelfixierung beim Öffnen des Hebels 7 zu keiner kurzzeitigen Betätigungskrafterhöhung führt. Das Element 78a kann z.B. in Form eines Stegs ausgebildet sein, der seitlich am Hebel 7 angeordnet ist und in einer Freimachung im angrenzenden Gehäuse 2 läuft und auf diese Weise jeweils eine Endlage des Betätigungshebels 7 festlegt/begrenzt. Die Fixierung des Betätigungshebels 7 gegenüber dem Isolierstoffgehäuse 2 erfolgt wie in den vorigen Ausführungsbeispielen über im vorderen Bereich des Betätigungshebels 7 angeordnete seitliche Rastmittel 78.A difference of the third embodiment of the conductor terminal to the previously described embodiments consists in the position and shape of an
Die erfindungsgemäße Leiteranschlussklemme in sämtlichen erläuterten Ausführungsformen weist zusätzlich einen optimierten Überlastschutz zum Schutz der Klemmfeder 5 bei zu schräg oder sonst wie unsachgemäß eingeführtem Leiter 8 in die Leiteraufnahmekammer 60 auf. Für solche Fälle muss die Klemmfeder 5 vor einer zu starken Belastung des zweiten Endbereichs 50 und des Bereichs, der vom zweiten Endbereich 50 bis zum etwa halbrunden, an der Wand 23 entlang verlaufenden Federbogen reicht, geschützt werden. Dies wird dadurch realisiert, dass die Klemmfeder 5 mit ihrem zweiten Endbereich 50 sich bis zu dem abgeschrägten Abschnitt 31 des Isolierstoffgehäuses, der als Leitereinführungsschräge wirkt, erstreckt. Der als Teil des Isolierstoffgehäuses 2 ausgeführte abgeschrägte Abschnitt 31 reicht dabei im Ausführungsbeispiel bis unterhalb des oberen Abschnitts 32 des Kontaktstücks. Dieser abgeschrägte Abschnitt 31 wirkt somit zugleich als Anschlag für den zweiten Endbereich 50 der Klemmfeder 5, so dass diese nicht weiter nach oben hin ausgelenkt werden kann.The conductor connection terminal according to the invention in all of the explained embodiments additionally has an optimized overload protection for protecting the
Der Teil des Kontaktstücks 3, an dem der Betätigungshebel 7 sich zumindest in der geöffneten Stellung und ggf. auch weiteren Stellungen abstützt, insbesondere in Positionen vor Erreichen der geöffneten Stellung, kann als in Rotationsrichtung des Betätigungshebels beim Öffnen ansteigende Rampe, abfallende Rampe oder als neutrale Fläche ohne Neigung ausgebildet sein. Die zuvor beschriebene erste und dritte Ausführungsform der Anschlussklemme zeigen eine Ausbildung als ansteigende Rampe, die zweite Ausführungsform als neutrale Fläche. Ebenso kann eine abfallende Rampe realisiert sein, indem der obere Abschnitt 32 des Kontaktstücks 3 nicht, wie z.B. in
