Description

Clamp with release lever and pusher

The present invention relates to a terminal and in particular to a connection or connection terminal for electrically connecting at least two electrical conductors, which has a release lever for selectively opening a first conductor clamping point and a pusher for selectively opening a second conductor clamping point.

Connection or connecting terminals for connecting at least two electrical conductors are known from the prior art. These are provided, for example, on an electrical consumer, with the external cabling (external electrical conductors) being connected to a first conductor terminal point and the internal cabling (internal electrical conductors) of the consumer being connected to a second conductor terminal point, so that the electrical consumer is connected via the external cabling , the terminal and further to supply power and/or transmit (control) signals via the internal cabling.

Connection or connecting terminals are known which make it possible to selectively open the conductor terminal points. This, for example, is used to remove the electrical conductors (e.g. for maintenance purposes) or to connect flexible electrical conductors.

Different mechanisms are known for selectively opening the conductor terminal points. There are terminals that have insertion openings in their insulating material housing for inserting a release tool with which the spring-loaded terminal connection can be manipulated directly and the conductor terminal point can thus be opened. A corresponding release tool is required for this. Improper use may result in damage to the clamp.

Clamps are also known which have integrated release elements. For example, terminals are known which have an integrated push button for each conductor clamping point. This can be operated by pressing on it (actuating force) - for example with a finger or a release tool. The pusher is pressed into the terminal so that an actuation section provided on the pusher interacts with the spring-loaded terminal connection to open the conductor clamping point. Since these pushers usually push back into their rest position after the actuating force has been removed, they require a permanent application of the actuating force during the insertion or removal of the electrical conductors in order to keep the conductor clamping point open. Alternatively, clamps are known which have release levers as release elements. These release levers are usually pivotally mounted in the insulating material housing of the terminal. The release lever can thus be pivoted from a rest position into an actuation position in order to interact with the spring-loaded terminal connection to open the conductor terminal point. The release lever is easy to use and can be operated without the use of any auxiliary tools.

It is therefore an object of the present invention to provide a clamp of the type mentioned at the outset, which enables functionally optimized and safe operation and conductor insertion or removal.

This task is solved by the subject matter of the independent claim. The dependent claims further develop the central idea of the present invention in a particularly advantageous manner.

According to a first aspect, the present invention relates to a terminal, in particular a connection or connecting terminal. The terminal has an insulated housing. Furthermore, the terminal has (at least) one spring-loaded terminal connection, which is at least partially accommodated in the insulating material housing. The spring-loaded terminal connection has (at least) two conductor clamping points for the respective electrical connection of at least one conductor. In addition, the terminal - for each conductor clamping point - has a conductor insertion channel which extends in a conductor insertion direction from the outside towards this conductor clamping point. The clamp also has a release lever. The release lever is assigned to a first of the conductor clamping points. The release lever is about a pivot axis extending transversely (preferably orthogonally) to the assigned conductor insertion direction between a lever rest position in which the first conductor clamping point is closed for connecting an electrical conductor, and a lever actuation position in which the first conductor clamping point is activated by interaction of the spring-loaded clamp connection with a lever actuation section of the Release lever is opened, pivotally mounted in the insulating housing. In addition, the terminal has a pusher, which is assigned to a second of the conductor clamping points and, by translational actuation from the outside of the pusher, from a pusher rest position in which the second conductor clamping point is closed for connecting an electrical conductor, into a pusher actuation position in which the second Conductor clamping point is opened by interaction of the spring-loaded clamp connection with a handle actuation section of the handle, is movable (preferably pivotable and / or bendable). By providing the two functionally different release elements, namely release levers on the one hand and pushers on the other, for the (at least) two conductor clamping points of the same spring-loaded clamp connection, it is possible to provide the clamp in an optimized manner for common cabling situations. For example, consumer-side cabling can be connected to the handle-side (second) conductor terminal point at the factory (so-called “factory wiring” on the device side of the terminal). This is done, for example, by fitters with tools intended for this purpose or by simply inserting - for example rigid or flexible conductors - by fitters or even automatically in production. The device side can therefore be provided with a safe but comparatively inexpensive release element. The external cabling is usually provided at the consumer's place of use by the customer himself or a local fitter at the (first) conductor terminal point on the release lever side (so-called "field wiring" on the installation side of the terminal). By using release levers, the customer can easily identify the installation side intended for connecting the external cabling. A simple and safe means of reducing assembly errors can thus be provided. In addition, the release lever is easy to use and can be operated without additional tools, which makes assembly easier for the customer and, in the best case, allows assembly to be carried out by just one person. A clamp is thus provided which, on the one hand, provides release elements tailored to different functional sides (e.g. device side on the one hand and installation side on the other), which can also be operated safely but in a cost-optimized manner.

Unless otherwise stated, the conductor clamping point, the conductor insertion channel and the conductor insertion direction always refer to the functionally assigned elements of the same conductor clamping point; In the context of the present invention, for example, sometimes also described by the term “assigned”.

The release lever has two lever arm sections which are spaced apart from one another and which are at least partially immersed in the insulating material housing on both sides of the associated conductor insertion channel. By providing two spaced lever arm sections, the release lever can be stored securely in the insulating material housing. The release lever can therefore be operated easily and safely. Since the lever arm sections are provided on both sides of the assigned conductor insertion channel, the release lever can penetrate deep into the insulating material housing, so that an overall flat design of the terminal with release lever is possible. The lever arm sections can preferably each have a guide section which faces one another and forms at least part of the conductor insertion channel between them. Consequently, the clamp can be made narrow overall.

If the guide sections are present, they can preferably run in the lever rest position and/or in the lever actuation position in the conductor insertion direction, narrowing the (assigned) conductor insertion channel towards the first conductor clamping point; Therefore, they preferably run towards each other, viewed in the conductor insertion direction, towards the first conductor clamping point, at least partially narrowing the conductor insertion channel. The guide sections (which at least partially form the conductor insertion channel) enable an electrical conductor to be inserted into the terminal to be guided towards the first conductor clamping point. Since the lever arm sections narrow the conductor insertion channel towards the first conductor clamping point via their guide sections, at least one (lateral) area of the conductor insertion channel that is otherwise located solely in the insulating material housing - facing the first conductor clamping point - can be displaced into the release lever - possibly even the entire (lateral area) of the conductor insertion channel . The terminal can therefore be made short in terms of its length when viewed in the conductor insertion direction. Since at least the narrowing of the conductor insertion channel is now relocated to the release lever, a transition to the release lever that would otherwise only be located in a narrowed area of the conductor insertion channel is widened, which in turn can reduce the risk of a conductor to be inserted tilting. In principle, the conductor insertion channel formed in this way - and in particular the partially narrowing course of the guide sections - can preferably have any course or contour that enables conductor insertion and thus a defined guidance of an electrical conductor to be inserted towards the first conductor clamping point. Preferred - but not limiting the invention - are courses that are as flowing or wavy as possible and preferably non-step-shaped or that do not change abruptly in cross-section towards the first conductor clamping point.

If the guide sections are present and provided with the aforementioned narrowing in the lever rest position, the insertion of a rigid conductor can be made easier and safe even if the first conductor clamping point is not opened by the release lever. If the guide sections are present and provided with the aforementioned narrowing in the lever actuation position, the insertion of a flexible conductor can also be made easier and safe when the first conductor clamping point is opened by the release lever. Depending on the area of application and desire, the optional guide sections with the narrowing mentioned can be either only in the lever rest position or only in the lever actuation position or preferably both in the The lever rest position as well as in the lever actuation position - and if necessary also in any pivot position in between - must be present.

If the guide sections are present, they can preferably run the conductor insertion channel continuously narrowing or flowing towards the first conductor clamping point, viewed in the conductor insertion direction. In this way, a particularly simple and safe guiding and sliding of the conductor along the guide sections towards the first conductor clamping point can be made possible. A continuous course enables targeted guidance towards the first conductor clamping point. Overall, a flowing course enables a course that is optimally adapted to the conditions and space requirements while maintaining miniaturization and safe guidance of the conductor to be inserted. For example, if necessary, the optional guide sections can also have sections that are partly parallel to the conductor insertion direction and partly narrowed, as long as there is a narrowing overall towards the first conductor clamping point, and the narrowing is provided by flowing contours, which ensure safe and easy guidance/Eq information from a leader to be introduced.

If the guide sections are present, they can preferably each have a first and a second guide section, which each face one another. The first guide section of one guide section then faces the first guide section of the other guide section. Likewise, the second guide section of one guide section then faces the second guide section of the other guide section. On the one hand, in the lever rest position, the first guide sections, viewed in the conductor insertion direction, then run narrowing the conductor insertion channel towards the first conductor clamping point, preferably continuously narrowing or flowing. These then lie in the lever rest position of the release lever on both sides of the assigned conductor insertion channel and delimit it laterally on opposite sides. On the other hand, in the lever actuation position, the second guide sections, viewed in the conductor insertion direction, then run narrowing the conductor insertion channel towards the first conductor clamping point, preferably continuously narrowing or flowing. These are then located in the lever actuation position of the release lever on both sides of the assigned conductor insertion channel and delimit it laterally on opposite sides.

By providing the two aforementioned optional guide sections, a particularly optimized embodiment can be achieved for correspondingly narrowing the (first) conductor insertion channel assigned to the release lever both in the lever rest position and in the lever actuation position. This is particularly advantageous the further the Pivot axis is spaced from the first conductor insertion channel or its center as seen in the (first) conductor insertion direction. The guide sections can be designed to be aligned with the respective pivoting positions of the release lever in order to always ensure optimal conductor guidance in every desired pivoting position. For example, even in a case in which the pivot axis crosses the first conductor insertion channel in the middle, the narrowest point can be provided in the area of the pivot axis and this can be expanded as the distance to the pivot axis increases (at least against the first conductor insertion direction). With a simple geometry of the guide sections, a particularly good conductor insertion can always be made possible over a large and preferably every possible pivoting range.

In principle, the optional guide sections or their optional guide subsections can have any shape or geometry in order to provide a corresponding constriction at least in the two release lever positions mentioned, but preferably also between them or even over the entire pivoting range of the release lever, and thus a particularly simple and safe one To enable ladder introduction. For example, the guide sections or their guide subsections can each be concavely curved and preferably concavely curved away from the (associated or first) conductor insertion channel. These guide sections or their guide subsections can also each be designed in a bowl-shaped manner (i.e., for example as a bowl-shaped recess or recess) in the respective lever arm section. In addition to a simple geometry, this enables a particularly flowing course and therefore a particularly safe and easy conductor insertion.

The optional guide sections, preferably their guide sections, can preferably be formed by a change in the material thickness of the respective lever arm section - preferably axially with respect to the pivot axis. A simple structure of these guide sections can thus be provided. These are also particularly easy to provide; for example in a (plastic) injection molding process.

The optional guide sections facing one another, preferably their guide sections, can preferably be designed to be mirror-symmetrical to one another; therefore preferably with respect to a plane of symmetry having the (first) conductor insertion direction and lying centrally between the lever arm sections. This makes it possible to safely and uniformly insert an electrical conductor into the terminal and towards the first conductor clamping point; This is preferably done on one installation side of the terminal to easily carry out “field wiring”. The lever arm sections can each have part-circular sliding sections which extend around the pivot axis and are directed radially away from the pivot axis. These then interact with corresponding housing sliding sections of the insulating material housing for sliding guidance of the release lever around the pivot axis. The bearing forces of the release lever can be easily distributed and absorbed in the insulating housing.

The sliding sections preferably have first sliding part sections which extend with respect to the pivot axis along a first circle with a first diameter d; this preferably in the area of the respective guide sections. The sliding sections further comprise second sliding part sections which extend with respect to the pivot axis along a second circle with a second diameter D, which is preferably larger than the first diameter d; this preferably in the area outside the respective guide sections. The lever arm sections can thus be designed to be optimized according to their desired purpose. For example, the first sliding part section can provide a desired length for narrowing the (first) conductor insertion channel; this is defined, for example, by the circular area of the first circle. On the other hand, the second sliding part section can have a desired distance (defined by the radius of the second circle) for secure storage. Particularly preferably, the second sliding part sections have or form the respective lever actuation sections. In this respect, an optimized length and thus a defined lever arm can be provided for opening the first conductor clamping point.

The lever arm sections can preferably each extend essentially in an extension plane. These extension planes are particularly preferably aligned parallel to one another and more preferably orthogonal to the pivot axis. The term “essentially extends in an extension plane” means that the lever arm sections can have a basic extension in the extension plane, while they are comparatively flat transversely thereto and can of course vary in width, for example in order to provide the optional guide sections, for example as a surface contour or to provide other structural elements.

The release lever can preferably have latching structures which interact with corresponding housing latching structures of the insulating material housing in such a way that the release lever is held releasably latching in the lever rest position and/or in the lever actuation position. The corresponding structures for the locking connection mentioned are designed in such a way that an operator can either bring the release lever into this locking connection and also release it again. In addition, it should Snap connection can hold the release lever independently in this position. So the locking connection in the lever actuation position may have to counteract a spring force of the opened first conductor clamping point. An operator can easily insert or remove a conductor. In the lever rest position, the release lever should remain securely “cleared away” so that the maximum compactness of the clamp is maintained during operation and the risk of accidental manipulation of the release lever is minimized.

The release lever, preferably the lever arm sections, can have first pivot bearing sections which cooperate with corresponding second pivot bearing sections of the insulating material housing for pivotally mounting the release lever around the pivot axis. This means that a safe and simple pivot bearing can be provided with a simple geometry of the release lever. The first pivot bearing sections can particularly preferably be provided on or in a side of the lever arm sections facing away from the assigned (first) conductor insertion channel. The pivot bearing can therefore be designed to save space. On the other hand, this is then provided facing away from the guide sections, so that when a conductor is inserted, it presses the lever arm sections into the bearing connection when it comes into contact with the guide, so that the bearing is safely maintained in every lever actuation position. The pivot bearing sections can, for example, be designed as a projection (second pivot bearing sections; for example in the form of a pin) and a recess which pivotally receives the projection (first pivot bearing sections; for example in the form of a blind hole or a groove).

The release lever preferably has a lever operating section for moving the release element about the pivot axis, preferably between the lever rest position and the lever actuation position. The lever operating section can preferably extend essentially in one plane. The lever operating section can also preferably extend between the lever arm sections and particularly preferably connect them to one another. In this way, an actuation point of the release lever can be made particularly stable. In addition, the lever operating section provides a comfortable manipulation point for an operator. Particularly preferably, the lever operating section on the one hand and the lever operating section on the other hand are provided at opposite ends of the release lever in order to provide a particularly advantageous distribution of the functional sections around the pivot axis, in particular to obtain an advantageous lever arm distribution.

The pivot axis can be laterally outside the assigned (first)

Extend conductor insertion channel. The pivot axis preferably intersects the associated one (first) conductor insertion channel or an extension of the assigned (first) conductor insertion channel seen in the conductor insertion direction. On the one hand, this creates space for the connecting section and, on the other hand, the (first) conductor insertion channel remains freely accessible. This means that an overall stable release lever design can be achieved while at the same time having a compact design of the clamp. In principle, if necessary, the pivot axis can also run through the (first) conductor insertion channel.

The insulating material housing can preferably have guide wall sections which at least partially form or delimit the associated (first) conductor insertion channel; this preferably together with the release lever, and also preferably with the guide sections of the same. A (first) conductor insertion channel can thus be provided for overall safe conductor insertion towards the first conductor clamping point.

The conductor insertion channel preferably extends beyond the assigned conductor clamping point in order to securely accommodate a distal conductor end when the electrical conductor is connected in this conductor clamping point.

Preferably, the respective conductor insertion channels are designed to be closed all around when viewed in their conductor insertion direction; this preferably over at least part and preferably over its entire length from the outside to the assigned conductor clamping point and, if necessary, beyond this conductor clamping point. An electrical conductor can thus be safely held in the terminal and guided to the appropriate conductor terminal point.

The guide wall sections can also have lateral wall sections which at least partially delimit the associated (first) conductor insertion channel axially on both sides with respect to the pivot axis. This means that lateral migration of a conductor to be inserted into this conductor insertion channel can be avoided particularly effectively.

Preferably, the lateral wall sections merge smoothly into the respective guide section, at least on the side of the assigned (first) conductor insertion channel and at least in the lever rest position or in the lever actuation position, viewed in the conductor insertion direction. Particularly preferably, these extend flatly into one another. In this way, a uniform (first) conductor insertion channel can also be formed in the transition between the insulating material housing and the release lever. This in turn enables a particularly safe and easy insertion of an electrical conductor into the terminal. The insulating material housing preferably has a cover wall which, in the lever rest position of the release lever, extends between a support section of the release lever and the pivot axis above the associated (first) conductor insertion channel. The clamp is then designed in such a way that the support section is preferably supported in a sliding manner on the cover wall when the release lever is pivoted around the pivot axis. On the one hand, the spring-loaded terminal connection can be covered at the top on the side of the first conductor terminal connection or the first conductor insertion channel. On the other hand, the release lever can be securely supported on the insulating material housing.

The insulating material housing can also have partition wall sections which limit the release lever, preferably at least the lever arm sections, axially on both sides at least partially on the outside with respect to the pivot axis. In other words, the partition wall sections lie laterally next to the release lever when viewed in the conductor insertion direction. In this way, for example, the release lever can be safely guided laterally during its pivoting movement. If the guide sections form a narrowing of the (first) conductor insertion channel, the release lever can also be supported in a particularly simple and safe manner relative to the insulating material housing when an electrical conductor is inserted into the terminal and over the narrowing (first) conductor insertion channel to the first conductor clamping point to be led. The clamp can also be constructed to be particularly stable overall. In addition, the partition wall sections can contribute to extending the clearance and creepage distance.

The optional partition wall sections particularly preferably have the second pivot bearing sections, thereby providing stable and secure storage.

The pusher can preferably have a bearing section with which the pusher is mounted on a counter-bearing section of the insulating material housing. Furthermore, the pusher can have a pusher section which protrudes from the bearing section, preferably in the pusher rest position parallel to the conductor insertion direction, such that the pusher can be moved from the pusher rest position into the pusher actuation position by translational actuation from the outside on the pusher section; For this purpose, it is preferably pivotable or bendable about the bearing section. The pusher can thus be held simply but securely in the insulating material housing by means of the bearing section. Since the pressing section protrudes accordingly, it can serve as a lever arm to easily operate the pusher. A corresponding triggering force can also be determined as required over the length of this pressing section. The pusher can preferably be snapped onto the counter-bearing section of the insulating material housing by means of the bearing section (preferably in a snap-on direction parallel to the translational actuation direction of the pusher), so that the pusher is easy to assemble and at the same time securely held.

The pressing section and the lever operating section preferably extend with respect to parallel extension axes. In this way, a compact terminal can be provided. Intuitive operation is also possible.

The pressing section and the lever operating section preferably extend away from each other. The device side and the installation side can thus be provided spatially separately, which enables a clear assignment of the respective sides and consequently assembly errors can be minimized.

The handle actuation section can preferably have two spaced-apart projection sections, which are at least partially immersed in the insulating material housing on both sides of the associated conductor insertion channel in order to cooperate in the handle actuation position with the spring-loaded terminal connection to open the second conductor clamping point. A simple and effective means for opening the second conductor clamping point is thus provided. Since the projection sections are also provided on both sides, an even force can be achieved and tilting of the pusher can be reliably avoided.

The spring-loaded terminal connection can also have a busbar and a clamping spring with a movable clamping leg for each conductor clamping point. The clamping leg can have a clamping section, preferably in the form of a clamping edge, to form the respective conductor clamping point between the clamping section and the busbar. In this way, conductor clamping points can be provided which can be opened easily using the given release elements (i.e. release lever, push button).

For some or all of the conductor clamping points, the associated busbars of a spring-loaded clamp connection are preferably electrically connected to one another and particularly preferably formed integrally with one another. An electrical connection can be made possible via separate electrical conductors. However, it is preferred if the spring-loaded terminal connection has a single, integral busbar for all conductor terminal points, via which the corresponding conductor terminal points are then electrically connected to one another. This enables safe electrical guidance from the release lever side to the pusher side or vice versa. With integrally provided busbar Manufacturing and assembly can also be simplified and power supply can be improved.

The clamping spring, more precisely the clamping leg, can, at least in the closed position of the associated conductor clamping point, extend transversely through the associated conductor insertion channel, viewed in the corresponding conductor insertion direction, in order to form an insertion slope towards the respective conductor clamping point. This enables particularly safe conductor insertion directed up to the respective conductor clamping point.

The spring force clamping connection, preferably its clamping spring, can have a spring actuation section which is arranged such that it cooperates with the lever actuation section or the pusher actuation section (e.g. its projection section) for selectively opening the associated conductor clamping point. The provision of a defined spring actuation section makes it possible to separate the corresponding functional areas of the spring force clamp connection for clamping on the one hand and for actuation on the other hand and thus enable an effective design of the spring force clamp connection.

The pusher actuation section, preferably its projection sections, can/can extend, preferably from the pusher section, towards the clamping spring or its clamping leg or the spring actuation section. This enables a compact design with an effective actuation function using the pusher.

The release lever, preferably its lever actuation section, on the one hand, and the spring-loaded clamp connection, preferably the associated clamping spring or its clamping leg or its spring actuation section, on the other hand, can preferably be designed and interact in such a way that the release lever automatically remains in the lever actuation position. In this way, inserting or removing an electrical conductor on the lever side can be simplified and, for example, can be carried out easily and safely with just one person.

The pusher, preferably its pusher actuation section, on the one hand, and the spring force clamping connection, preferably the associated clamping spring or its clamping leg or its spring actuation section, on the other hand, can preferably be designed and interact in such a way that the pusher automatically pushes from the pusher actuation position into the pusher rest position. This means that - for example, with factory-side and preferably automated assembly or customer-side assembly Maintenance - ensure that the device side clamps securely when the conductor is inserted. This functionality can also be provided with a simple structural design, which enables a safe and cost-effective solution.

The at least two conductor clamping points and the conductor insertion channels assigned to them are preferably arranged one above the other or directed towards one another. The conductor insertion directions of the conductor insertion channels assigned to the conductor clamping points are preferably aligned parallel or coaxial to one another. This means that, on the one hand, a compact terminal can be provided, which also enables any defined conductor feed - depending on the desired location and purpose.

In addition to the two conductor clamping points, the spring-loaded clamping connection can have further conductor clamping points, which are, for example, adjacent to the first and second conductor clamping points. It is therefore conceivable that these additional conductor clamping points are also provided with a clamping spring. This can be a separate clamping spring. Also, for example, one of the further conductor clamping points can share a clamping spring with one of the first or second conductor clamping points. The common clamping spring then has the respective clamping leg with a clamping section at its two distal ends, which are connected to one another via a connecting section (e.g. an arcuate section). The two clamping legs can each be pivoted via this connecting section in order to expose the associated conductor clamping point or to clamp an electrical conductor between it and the corresponding busbar for electrical connection. This means that a terminal can be provided with any number of conductor clamping points. The other conductor clamping points can do without assigned release elements. Depending on requirements, one of the release elements described above (i.e. release lever or pusher) can also be assigned to these in a comparable manner.

The clamp can preferably have several of the spring-loaded clamp connections. The first conductor clamping points and the second conductor clamping points are then preferably each arranged in a row next to one another. The conductor insertion directions of the conductor insertion channels assigned to the first conductor clamping points are then preferably aligned parallel to one another. The conductor insertion directions of the conductor insertion channels assigned to the second conductor clamping points can then preferably be aligned parallel to one another. This means that a terminal can be provided for any purpose and any number of poles.

Consequently, it is conceivable that there are several in a corresponding terminal

Spring-loaded terminal connections are provided or the spring-loaded terminal connection is designed in several parts or in several parts. For example, the spring-loaded clamp connection can have a one-piece busbar with several clamping springs to form a corresponding number of conductor clamping points. Several (in particular two) conductor insertion channels can also share a clamping spring, for example in that their opposite legs each form a clamping leg for one of two adjacent conductor insertion channels. The opposite legs then preferably press against opposite clamping points of one busbar (or several busbars) to form a conductor clamping point. The busbar can also be designed in several parts and form a corresponding number of conductor clamping points with only one or part of the clamping springs.

The pushers of the plurality of spring-loaded clamp connections can preferably be formed integrally with one another; further preferred as an integral plastic injection molded part. In this way, the stability of the pushers can be increased, their handling simplified and the costs for production and assembly reduced.

The figures show different views of a terminal 1, in particular a connection or connecting terminal, according to the present invention.

The terminal 1 has an insulating material housing 6. The insulating material housing 6 is made of an electrically non-conductive material, such as plastic. This is preferably done in an injection molding process. The insulating material housing 6 can be designed in one piece or preferably in several parts. In the case of a multi-part design, the corresponding parts of the insulating material housing 6 can be connected to one another in a detachable or non-detachable manner, for example by means of corresponding locking elements and/or welding and/or gluing. The insulating material housing can have a mechanical fastening element 9 for fastening the terminal 1; here in the form of two snap projections projecting downwards.

The terminal 1 also has a spring-loaded terminal connection 2, which is at least partially - and here completely (cf. Fig. 5-10) - accommodated in the insulating material housing 6. The spring-loaded terminal connection 2 has at least two - here four (see Fig. 5-10) - conductor clamping points K1 to K4 for the respective electrical connection of at least one conductor Li, L2, as can be seen in particular in FIGS. 7-10.

The spring-loaded terminal connection 2 preferably has, as shown, a busbar 3 and a clamping spring 4 with a movable clamping leg 42 for each conductor clamping point Ki-K4. The clamping leg 42 in turn preferably has a clamping section 421, here preferably in the form of a clamping edge, to form the respective conductor clamping point K1-K4 between the clamping section 421 and the busbar 3. The spring-loaded terminal connection 2 can provide a single, integral busbar 3 for part or, as shown in FIGS are connected.

As shown in particular in FIGS. 5 to 10, the clamping spring 4 can have two clamping legs 42, 40, which are connected to one another via a connecting leg 41 - here in the form of a spring arch. The respective clamping section 421, 401 can preferably be provided on a free end of the clamping spring 4 or the respective clamping leg 42, 40 facing away from the spring bow 41 - here preferably on opposite distal ends of the clamping spring 4. Alternatively, instead of the second clamping leg 40 (the lower clamping leg 40 in FIGS. 5-10), the clamping spring 4 can have a contact leg, which supports the clamping spring 4 in the busbar 3 or the insulating material housing 6, and from which the spring arch 41 extends, and from which the (here upper) clamping leg 42 then extends, for example to form a substantially U-shaped clamping spring 4.

The terminal 1 also has a conductor insertion channel 60 for each conductor clamping point K1-K4, which extends in a conductor insertion direction E from the outside to this conductor clamping point K1-K4. The conductor insertion channel 60 may be formed or limited by different areas and sections of the terminal 1, as will be described below by way of example; preferably at least through the insulating material housing 6.

The at least two conductor clamping points K1-K4 and the conductor insertion channels 60 assigned to them are preferably one above the other (as with regard to the conductor clamping points K1 and K3 on the right side of the terminal 1 or as with regard to the conductor clamping points K2 and K4 on the left side of the terminal 1 in Fig. 5-10 can be seen as an example) and/or directed towards each other (as with regard to the conductor clamping points K1 and K2 on the upper side of the terminal 1 or as with regard to the conductor clamping points K3 and K4 on the lower side of the terminal 1 can be seen as an example in FIGS. 5-10). The conductor insertion directions E of the conductor insertion channels 60 assigned to the conductor clamping points K1-K4 are preferably at least partially or, as shown here, all aligned parallel to one another. The conductor insertion directions E of the two upper conductor clamping points K1, K2 and the conductor insertion directions E of the two lower conductor clamping points K3, K4 are preferably aligned coaxially to one another here.

As can be seen from Figures 1, 2 and 5-10, the terminal 1 also has a

Release lever 5. The release lever 5 is a first of the conductor clamping points Kl (in Fig. 5- io assigned to the conductor terminal point Ki at the top right). The release lever 5 is pivotably mounted in the insulating material housing 6 about a pivot axis A extending transversely to the associated conductor insertion direction E. The release lever 5 is between a lever rest position (see FIGS. 1-6, 9 and 10), in which the first conductor clamping point Kl is closed for connecting an electrical conductor Li, and a lever actuation position (see FIGS. 7 and 8), in which the first conductor clamping point Kl is opened by the interaction of the spring-loaded clamp connection 2 with a lever actuation section 52 of the release lever 5, pivotally mounted in the insulating material housing 6 about the pivot axis A.

The release lever 5 can preferably have latching structures 55a, 55b, which interact with corresponding housing latching structures 65a, 65b of the insulating material housing 6 in such a way that the release lever 5 is held in a releasably latching manner in the lever rest position and/or in the lever actuation position. Figures 5, 6, 9 and 10 show this releasably latching connection of (first) latching structure 55a and (first) housing latching structure 65a in the lever rest position of the release lever 5. The release lever 5 can thus be securely held in the lever rest position when the clamp 1 is transported or is installed and electrically connected for operation. Figures 7 and 8 show the releasably latching connection of (second) latching structure 55b and (second) housing latching structure 65b in the lever actuation position of the release lever 5. The release lever 5 can thus be held securely in the lever actuation position when it reaches the first conductor clamping point Kl for insertion or Removing an electrical conductor keeps Li open, which increases the ease of use of terminal 1.

The release lever 5 may have a lever operating section 51 for moving the release lever 5 about its pivot axis A, preferably between the lever rest position and the lever actuation position. The lever operating section 51 can preferably extend essentially in one plane. The lever operating section 52 and the lever operating section 51 are particularly preferably provided at opposite ends of the release lever 5, as can be seen in particular from FIGS. 5 to 10.

As can be seen in particular from FIGS. 5 to 10, the pivot axis A preferably extends laterally outside the associated conductor insertion channel 60 and here above it. The pivot axis A therefore does not intersect the associated conductor insertion channel 60 or an extension of the associated conductor insertion channel 60 when viewed in the conductor insertion direction E. In principle, however, the invention is not limited to this. The pivot axis A can also cross the conductor insertion channel 60; preferably in the middle. The release lever 5 preferably has two spaced apart lever arm sections 50, which here are at least partially immersed in the insulating material housing 6 on both sides of the associated conductor insertion channel 60 (i.e. seen here in the conductor insertion direction E), as can be seen in particular from the sectional views in FIGS. 5 to 10.

As can be seen by way of example from FIG. 1, the lever arm sections 50 preferably each extend essentially in an extension plane X. The extension planes X are preferably aligned parallel. These extension planes X are particularly preferably aligned orthogonally to the pivot axis A.

Preferably, the lever operating section 51 can extend between the lever arm sections 50 and connect them to one another, as can be seen by way of example in FIG. 1.

The lever arm sections 50 can preferably each have a guide section 53, which face one another and form or delimit at least part of the conductor insertion channel 60 between them (see, for example, FIGS. 5 to 10). This preferably applies to every movement position of the release lever 5 around the pivot axis A.

In a preferred embodiment, the guide sections 53 can narrow the conductor insertion channel 60 at least in the lever rest position, or at least in the lever actuation position, or - as shown in the illustrated exemplary embodiment - at least in the lever rest position and in the lever actuation position in the conductor insertion direction E towards the first conductor clamping point Kl . The guide sections 53 converge towards each other towards the first conductor clamping point Kl, so that a distance between the guide sections 53 is reduced and consequently, in particular, the width of the associated conductor insertion channel 60 is reduced; this is therefore narrowed towards the first conductor clamping point Kl. The guide sections 53 particularly preferably run in the conductor insertion direction E towards the first conductor clamping point Kl, continuously narrowing or flowing the conductor insertion channel 60.

In one embodiment, it is conceivable that the guide sections 53 run narrowing the associated conductor insertion channel 60 in each pivot position of the release lever 5 between the lever rest position and the lever actuation position in the conductor insertion direction E towards the first conductor clamping point Kl. This can be done either by a specific geometric design or contouring of the guide sections 53 take place. For example, the narrowest area can also be provided in the area of the pivot axis A and expand as the distance from it increases.

It is also conceivable that the guide sections 53 each have a first guide section 53a and a second guide section 53b, which each face one another. In the lever rest position (see, for example, FIGS. 5, 6, 9, 10), the first guide sections 53a then run in the conductor insertion direction E towards the first conductor clamping point Kl, narrowing the conductor insertion channel 60, preferably continuously narrowing or flowing. In the lever actuation position (see, for example, FIGS. 7 and 8), the second guide sections 53b then run in the conductor insertion direction E towards the first conductor clamping point K1, narrowing the conductor insertion channel 60, preferably continuously narrowing or flowing.

The guide sections 53, and here the guide sub-sections 53a, 53b, can each be curved concavely away from the conductor insertion channel 60 or be cup-shaped in the respective lever arm section 50. The guide sections 53 or their guide sections 53a, 53b can preferably be formed by a change in the material thickness of the respective lever arm section 50 - preferably axially with respect to the pivot axis A.

In principle, it is also conceivable that the optional guide sections 53 run differently, for example extend parallel to the conductor insertion channel 60. It is also conceivable that the lever arm sections 50 do not directly delimit the conductor insertion channel 60 laterally. In this case, for example, a section of the insulating material housing 6 can at least partially spatially separate the lever arm section 50 from the conductor insertion channel 60.

The insulating material housing 6 can also have guide wall sections 63 which at least partially form or delimit the associated conductor insertion channel 60; this preferably together with the release lever 5 or its guide sections 53, as shown by way of example in FIGS. 5-10. The guide wall sections 63 can have lateral wall sections 630, which at least partially delimit the conductor insertion channel 60 axially on both sides with respect to the pivot axis A.

The lateral wall sections 630 can preferably be seen flowing in the respective conductor insertion direction E at least on the side of the associated conductor insertion channel 60 and at least in the lever rest position or in the lever actuation position Pass over the guide section 53, whereby these particularly preferably extend flatly into one another, as can also be seen as an example in Figures 5-10.

5-10, the spring-loaded terminal connection 2 on the side of the insulating material housing 6, on which the release lever 5 is arranged here, can be at least partially covered by an outer (here upper) cover wall 62 of the insulating material housing 6. The cover wall 62 here preferably extends in the lever rest position of the release lever 5 between a support section 57 of the release lever 5 and the pivot axis A above the associated conductor insertion channel 60. The clamp 1 is then designed in such a way that the support section 57 moves around when the release lever 5 is pivoted Pivot axis A is preferably supported in a sliding manner on the cover wall 62, as can be seen, for example, from the synopsis of Figures 6 and 8.

The lever arm sections 50 can each have part-circular sliding sections 56 which extend around the pivot axis A and are directed radially away from the pivot axis A and which cooperate with corresponding housing sliding sections 66 of the insulating material housing 6 for sliding guidance of the release lever 5 around the pivot axis A, as exemplified in the Figures 5 and 9 are shown.

Also with reference to Figures 7 and 8, the sliding sections 56 can have first sliding part sections 56a, which extend with respect to the pivot axis A along a first circle Ci with a first diameter d, preferably in the area of the respective guide sections 53. Consequently, corresponding first housing sliding part sections 66a extend the housing sliding sections 66 correspondingly also along the first circle Ci. The sliding sections 56 can then have second sliding part sections 56b, which extend with respect to the pivot axis A along a second circle C2 with a second diameter D, which is preferably larger than the first diameter d; this preferably in an area outside the respective guide sections 53. Consequently, corresponding second housing sliding part sections 66b of the housing sliding sections 66 also extend accordingly along the second circle C2.

As shown, in a preferred embodiment, the second sliding portions 56b may include or form the respective lever operating portions 52, so that the overall structure of the release lever 5 is simplified. This is particularly favored by a cam-like geometry of the lever arm sections 50 due to the above-described extension along the circles Ci, C2 with different diameters D, d, which can be seen in particular in FIGS. 5 and 9. The release lever 5 and preferably its lever arm sections 50 preferably each have/have a first pivot bearing section (not shown) on a side facing away from the conductor insertion channel 60, which are each connected to a corresponding second pivot bearing section (not shown) of the insulating material housing 6 for pivotally mounting the release lever 5 interact around the pivot axis A.

The first pivot bearing sections are preferably provided on or in a side of the lever arm sections 50 facing away from the associated conductor insertion channel 60 (i.e. here the outside). Therefore, in this embodiment, the first pivot bearing sections are provided on a side facing away from the guide sections 53 (here an inside facing the associated conductor insertion channel 60). Thus, an electrical conductor to be inserted into the conductor insertion channel 60, when it is slidably supported on the guide sections 53 for guidance towards the first conductor clamping point Kl, pushes the lever arm sections 50 further towards the second pivot bearing sections, so that a bearing connection via the pivot bearing sections is reliably maintained.

As can be seen from Figures 1, 2 and 5-10, the clamp 1 also has a pusher 7. The pusher 7 is assigned to a second of the conductor clamping points K2 (in Fig. 5-10 the conductor clamping point K2 at the top left). The pusher 7 is by translatory actuation P - here from top to bottom - from the outside on the pusher 7 from a pusher rest position (see Fig. 1-8), in which the second conductor clamping point K2 is closed for connecting an electrical conductor L2 a handle actuation position (see FIGS. 9, 10), in which the second conductor clamping point K2 is opened by the interaction of the spring-loaded clamp connection 2 with a handle actuation section 72 of the handle 7, is movable. For this purpose, the pusher 7 can be moved from the pusher rest position to the pusher actuation position using a finger by pressing on the pusher 7. It is also conceivable that a tool W is used for this, as shown as an example in FIGS. 9 and 10. For this purpose, the pusher 7 can have a tool receiving opening 76 - here in the form of a blind hole - into which a tool W can be inserted for secure reception and supported for safe operation.

The pusher 7 can have a bearing section 74 with which the pusher 7 is mounted on a counter bearing section 67 of the insulating material housing 6. As shown in Figures 5-10, the pusher 7 can preferably be snapped onto the counter-bearing section 67 of the insulating material housing 6 - here from above - by means of the bearing section 74. The counter bearing section 67 can, for example, be designed as a transversely extending, cylindrical bearing pin, as shown. The extension axis Z of the bearing section 74 is preferred aligned parallel to the pivot axis A. The bearing section 74 can preferably be formed by two snap arms 740, which surround the counter bearing section 67 on both sides. The placement direction or snap-on direction can preferably be aligned parallel to the translational actuation direction P of the pusher 7, so that the pusher 7 remains securely held in the actuation direction P even when it is actuated, since it is thus pressed even further in its fastening direction P.

The pusher 7 can further have a pusher section 71, which protrudes from the bearing section 74 in such a way that the pusher 7 can be moved from the pusher rest position into the pusher actuation position by the translational actuation P from the outside on the pusher section 71. The pusher 7 is preferably pivoted and/or bent around the bearing section, as can be seen in particular from FIGS. 9 and 10. The pressing section 71 preferably protrudes from the bearing section 74 in the pressing rest position parallel to the associated conductor insertion direction E, as can be seen, for example, in FIGS. 5-8.

5-10, the handle actuation section 72 can have two spaced-apart projection sections 70, which on both sides of the associated conductor insertion channel 60 are at least partially - and here completely - immersed in the insulating material housing 6 in such a way as to be in the handle actuation position with the spring-loaded terminal connection 2 to cooperate to open the second conductor terminal point K2. The pusher actuation section 72 or its projection sections 70 extend/extend - preferably from the push section 71 - to the clamping spring 4 or its clamping legs 42 or a spring actuation section 43 of the clamping spring 4 described below.

The insulating material housing 6 can also have partition wall sections 61 which at least partially delimit the pusher 7 or the release lever 5 - here axially with respect to the pivot axis A - on both sides. The partition wall sections 61 can at least partially form a lateral outer wall of the insulating material housing 6, as can be seen, for example, in FIG. The partition wall sections 61 facing the assigned first pivot bearing section can preferably have the respective second pivot bearing sections, if present. The partition wall sections 61 can be essentially flush with the pusher 7 or release lever 5 in a direction away from the conductor insertion channel 60 (here perpendicular to a conductor insertion direction E), at least when the conductor clamping point Ki, K2 is closed, or can at least partially protrude beyond it and/or with regard to . be at least partially set back to this. In the exemplary embodiments shown here, the pusher 7 is in the pusher rest position with respect to the Partition wall sections 61 are flush and the release lever 5 - except for a part of the second latching structure 55b - is arranged set back in the lever rest position with respect to the partition wall sections 61, as can be seen, for example, in Figures 1 and 4. The partition wall sections 61 can each extend at least partially essentially in a partition wall plane T, the partition wall planes T preferably extending parallel to the translational actuation direction P of the pusher 7 or perpendicular to the pivot axis A. As can be seen in particular from FIG. 1, the extension plane X and the partition plane T can each be aligned parallel to one another on one side of the corresponding conductor insertion channel 60.

As can be seen in particular from Figures 5-10, the clamping spring 4 or its clamping legs 42 can, at least in the closed position of the associated conductor clamping point K1-K4, extend transversely through the associated conductor insertion channel 60, viewed in the conductor insertion direction E, in order to create an insertion bevel to the respective one To form conductor terminal point K1-K4.

The spring clamp connection 2, preferably its clamping spring 4, can have a spring actuation section 43, which is arranged in such a way that it can be connected to the lever actuation section 52 or the pusher actuation section 72 (for example by means of the projection sections 70) for selectively opening the associated conductor clamping point Kl, K2 works together. The spring actuation section 43 preferably projects laterally (i.e. transversely to the conductor insertion direction E or to the extension direction of the clamping leg 42) and here in particular on both sides of the clamping leg 42, as can be seen, for example, in FIG. 6. By pivoting the release lever 5 from the lever rest position to the lever actuation position, the lever actuation section 52 is moved here along the second circle C2. The spring actuation sections 43 projecting on both sides lie on the movement path of the lever actuation section 52 and come into effective contact with it due to the pivoting movement. As a result, the clamping spring 4 or its clamping leg 42 is pivoted downwards and consequently the first conductor clamping point Kl is opened. This works in a similar way with the pusher 7, which, when actuated P from above in translation, moves the pusher actuating section 72 downwards into the insulating material housing 6, and through effective contact with the spring actuating sections 43, the clamping spring 4 or its clamping leg 42 pivots downwards and consequently the second conductor clamping point K2 opens.

The release lever 5, preferably its lever actuation section 52, on the one hand, and the spring-loaded clamping connection 2, preferably the associated clamping spring 4 or its clamping leg 42 or its spring actuation section 43, on the other hand, can be in this way be designed and cooperate so that the release lever 5 automatically remains in the lever actuation position, as indicated in FIGS. 7 and 8.

Likewise, the pusher 7, preferably its pusher actuation section 72, on the one hand, and the spring-loaded clamping connection 2, preferably the associated clamping spring 4 or its clamping leg 42 or its spring actuation section 43, on the other hand, can be designed and cooperate in such a way that the pusher 7 automatically pushes from the pusher actuation position into the pusher rest position , as can be seen from the synopsis of FIGS. 7-10.

The clamp 1 can preferably have several of the spring-loaded clamp connections 2, as can be seen by way of example in FIGS. 1, 4, 6, 8 and 10. The first conductor clamping points K1 and the second conductor clamping points K2 are preferably each arranged in a row next to one another. Likewise, the further conductor clamping points K3, K4 can also be arranged next to each other in a row. A corresponding release lever 5 and a corresponding pusher 7 are then assigned to the spring clamp connections 2 in the manner described above. The conductor insertion directions E of the conductor insertion channels 60 assigned to the first conductor clamping points Kl can then preferably be aligned parallel to one another. Likewise, the conductor insertion directions E of the conductor insertion channels 60 assigned to the second conductor clamping points K2 can then also preferably be aligned parallel to one another. The same applies to the conductor insertion directions E of the conductor insertion channels 60 assigned to the further conductor clamping points K3, K4, if present. As can be seen from FIGS. 1, 6, 8 and 10, the pushers 7 of the plurality of spring clamp connections 2 can be formed integrally with one another; for example as an integral plastic injection molded part. The pivot axes A of the release levers 5 assigned to the plurality of first conductor clamping points Kl are preferably arranged at least partially - here all - in parallel or, as shown, even coaxially.

The terminal 1 or its insulating material housing 6 preferably has a test opening 8 in order to insert a testing tool for current and voltage testing into the terminal 1 or its insulating material housing 6 and to contact it with the spring-loaded terminal connection 2. The test opening 8 can be designed as a passage opening in the insulating material housing 6. As can be seen, for example, in FIGS. 1 and 5-10, the test opening 8 can be guided or limited by an area of the release lever 5; Here, for example, laterally limited by the lever arm sections 50, the cover wall 62 and the second housing latching structure 65b. The terminal 1 preferably has a ground contact 10; here in the form of a downwardly projecting latching contact.

The present invention is not limited by the foregoing embodiment as long as it is included in the subject matter of the following claims.
