Description

Description Distribution block

The invention relates to a distributor block, that is to say an assembly or an electrical device with means for multiple tapping (distribution) of a potential supplied on one connection side.

Manifold blocks or manifold assemblies, collectively referred to herein as manifold block, are well known in the art. Manifold blocks are used in electrical installation, for example in so-called distribution boxes for house connection or the like. Basically, wherever an added potential is passed on to several points, thus also when connecting electrical systems, for example in industry. In the following, without limitation of the general application possibility is always assumed by a distribution box as a mounting location. Manifolds are usually just one device of many devices that are mounted in distribution boxes for electrical installation. Even if no or only a few other components are to be provided in the same distribution box, it is often necessary to place a plurality of distribution blocks. Thus, in addition to compliance with the safety regulations for electrical equipment and the fulfillment of the relevant standards, the size of a distributor block is a decisive criterion for its usability in practice. In terms of size, especially the width of the construction is in the foreground. The smaller the width, the more manifold blocks can be placed side by side at the mounting location. Conventionally, electrical devices for electrical installation or for electrical or electronic systems are mounted on a mounting unit, for example a DIN rail. With a small width so far so a higher packing density of distribution blocks and other electrical Devices or a higher packing density of distribution blocks on a DIN rail possible.

A determining factor for the width of a distribution block is the maximum supply current that can be provided. The current, which the conductor can transport safely, that is, for example, without the risk of overheating, depends directly on the conductor cross-section. The higher a current to be transmitted via an electrical conductor, the larger the cross section of the conductor must be. For an amperage of 250 amps, assuming a common range for conductor lengths and common values for allowable voltage drop along the conductor when using one of the standardized cross sections provided in IEC 60228, a necessary conductor cross section of 120 mm ² results. In order to be able to introduce a round conductor with such a cross section into a bore provided for its connection, a bore with a diameter of 15 mm is required.

This means that known distribution blocks usually have only one connection point for an incoming conductor on their connection side in favor of a small overall width. Manifold blocks with two connection points have these holes formed in one plane or in slightly different planes but at least side by side on the connection side. The bores are normally formed in a clamp body encompassed by the distributor block. In addition to the outer sides of the clamp body and between adjacent bores, a wall thickness specified by standards must remain in order to comply with the relevant regulations regarding the operational safety and operability of such a manifold.

A disadvantage of known manifold blocks with two connection points on the tail side is accordingly that either the width increases to an unfavorable extent or that only holes with a comparatively small diameter are possible as connection points, so that the manifold block only Amperages can be supplied below a predetermined by the bore diameter threshold.

Accordingly, it is an object of the present invention to further develop known manifold blocks to improve, for example, their handleability or capabilities, in particular to provide a manifold block that avoids the disadvantages outlined above or at least reduces their effects. This object is achieved with the features of claim 1. In this case, the starting point is a distributor block having at least one or exactly one connection side and a first and second connection point provided there, the first and second connection points permitting the detachable connection of an electrical conductor in each case. This is characterized in particular by a movable against an underside of a clamping body fixing part and a remaining between a stop and an upper side of the fixing part gap. The clamping body, namely its side facing the connection side, is the location of the first connection point. The space between the stop and the top of the fixing part is the location of the second connection point.

The proposed distribution block has a first and second connection point and allows at both connection points the connection of electrical conductors and with such an electrical conductor, a supply of electric current with considerable current, for example 250 amps. The width of the distributor block is essentially determined by the width of the clamping body arranged in a housing of the distributor block. After the fixing part is movable against a lower side of the clamping body, the two connection points lie one above the other in two planes, so that the requirements with regard to the necessary wall thicknesses in the clamping body or the requirements with respect to necessary safety distances can be maintained in each level. The manageability or the possible uses of the distributor block are improved in that the distributor block has two connection points for electrical conductors with a comparatively large cross section, ie a cross section which allows the transmission of higher currents, for example 250 amperes, and that the distributor block nevertheless has a comparatively small size Has width. In distribution boxes or the like, more distributor blocks can be arranged next to one another in comparison with distributor blocks with a larger overall width.

In embodiments of the distributor block it is provided that the first connection parts have a circular insertion opening for connecting electrical conductors in the form of so-called circular conductors and / or that the second connection point has a rectangular insertion opening for connecting electrical conductors in the form of so-called flat conductors. In such an embodiment, the distributor block is suitable without modification regardless of a geometry of the respective incoming cable for the connection of such a cable and for the distribution of the potential supplied thereto. In previous distributor blocks with one or two circular insertion openings for incoming cables on the connection side, the connection of flat conductors is not possible or at least not yet possible. Accordingly, the embodiment with two connection points, each with a different geometry of the insertion openings therein, expands the application spectrum of the distribution block to rectangular geometries of incoming cables.

Further advantageous embodiments of the invention are the subject of further subclaims. Relationships used in subclaims indicate the further development of the subject of the main claim by the features of the respective subclaim; they should not be construed as a waiver of obtaining independent, objective protection for the feature combinations of the dependent claims. Furthermore, with a view to an interpretation of the claims in a closer specification of a feature in a subordinate claim, it is to be assumed that such a restriction does not exist in the respective preceding claims. If the first and second connection points are electrically conductively connected in the distributor block, a supply of a distributing electrical potential is alternatively but equally possible both at the first and at the second connection point, without such an electrically conductive inside or outside of the distributor block Connection must be made separately. In a particular embodiment, the electrically conductive connection of the first and second connection point is considered that an underside of the clamping body acts as a stop which forms the second connection point with the fixing part. By pressing a connected at the second junction electrical conductor with the fixing member against the stop, so the underside of the clamp body, results as in a normal Schraubklemmenverbindung or the like, an electrically conductive connection between the underside of the metallic and thus self-electrically conductive clamping body and the respective electrical conductor.

If the distributor block has means for independently actuating the first and second connection points from an upper side of the distributor block, the accessibility of such actuating means makes connecting an arriving electrical conductor to one of the two connection points relatively easy and clear and also takes place in one for the installer usual orientation / operating direction. If the actuating means can be actuated independently of one another, for example, a conductor can be connected to the second connection location, while a conductor (for example a bridge) already connected to the first connection location remains in electrically conductive contact with the clamping body.

For actuation of the movable against the underside of the clamping body fixing part of the distributor block comprises means for moving the fixing part in the direction of the clamping body, that is to move against the actuating direction of the actuating means or the actuating means. The means or means for moving the fixing part thus directs or deflects the action of the or each actuating means opposite to the actuating direction. As a means of such moving the fixing part is basically a lever mechanism into consideration, wherein on the lever on one side of the fulcrum of the attack or the actuating means and wherein the lever is combined on the other side of the fulcrum with the fixing part. Furthermore, as a means for such movement also a spring mechanism into consideration, in which, for example, a spring presses the fixing member against the underside of the clamping body when a locking of the spring or the fixing part is released.

If the distributor block has screws as means for moving the fixing member against the clamping body, which are guided in the clamping body in two holes formed therein and engage with their free ends in the fixing part in two threaded holes formed there, is a particularly simple way to the above outlined deflection given. The screws, in particular exactly two screws, are guided in two holes in the clamping body. Either the inner surface of the holes or a corresponding portion of the screw pin is thread-free, so that the screws are freely rotatable in the holes. The holes act as a bearing sleeve for the screws.

At least the free ends of the screw pins have a thread and thus engage in two threaded holes formed in the fixing part. The fixing part is rotatably supported by the simultaneous support with two screws in the housing of the manifold block. Even if one of the two screws should not be in engagement with the respective threaded hole in the fixing part, the housing of the distributor block causes such a rotationally fixed bearing. Anyway, when pressing one of the two screws results in that the fixing part is moved with its affected by the movement of the screw portion in the axial direction of the screw pin in the direction of the underside of the clamping body. This direction of movement is opposite to the direction of actuation with a screwdriver or the like for rotating the screw. If both

If the screws are actuated alternately, the fixing part is moved toward the underside of the clamping body in an approximately parallel orientation. With decreasing distance between the underside of the clamp body and fixing part is inserted into the space between the underside of the clamp body and fixing part electrical conductor fixed from a two-sided contact on the one hand with the clamping body and on the other hand with the fixing part at the second connection point.

If the distributor block has a bottom profile for detachable connection, in particular latching, with a mounting unit, in particular a DIN rail, the distributor block, like other electrical appliances, for example clamps, automatic circuit breakers and the like, can be installed on such a mounting unit in a distribution box or the like to be assembled. When the manifold block has a stackable side profile (bay profile), the manifold block may be combined with other manifold blocks or other electrical devices having a same side profile, for example, a main line branch terminal of the assignee of the present invention or the like. Due to the combinability, it is possible to produce a dressing of, for example, a plurality of distributor blocks which form a unit even without being combined with an assembly unit and thus can be moved and positioned as a whole.

The invention further relates to a system formed from manifold blocks of the type described here and below. A system with at least two such distribution blocks, in which the two distribution blocks are referred to as first and second distribution block, is characterized in that the first and second distribution block by a bridge between one of the two connection points of the first distribution block and one of the two connection points the second distribution block are electrically conductively connected or connectable. Such a system or such a group of two or more with one bridge electrically connected distributor blocks has the advantage that the supplied at one of the manifold blocks due to an electrical conductor connected there potential not only on the terminals of the output side of this distributor block but also on all output ports of all other covered by the system / group distribution blocks can be tapped. The number of output-side connection options can thus be almost arbitrarily and in such a way by such a group or system formation Increase dependence on the respective needs of the installation situation.

A particularly simple situation for the electrically conductive connection of two or in each case two distributor blocks combined in one system or one group results if the electrically conductive connection between the first and the second distributor block is established by a bridge between the first connection point of the first distributor block and the first connection point of the first distributor block second distributor block or the second connection point of the first distributor block and the second connection point of the second distributor block. The bridge thus always connects two quasi-identical connection points, either two first connection points or two second connection points. Specifically, because one of the two connection points of each distributor block is provided for connecting round conductors and the complementary connection point for connecting flat conductors, preconfigured bridges can be used which each have an identical geometry at their contact points, ie either a circular or a rectangular cross-sectional contour. Especially when in a system or a group of two or more distribution blocks, the individual manifold blocks are combined with each other, for example via a lateral Anreih profile, results in a defined, always consistent distance between each two adjacent first or second connection points of juxtaposed manifold blocks. Due to the distance known so far of the connection points is also a necessary dimension of bridges for electrically conductive connection of the manifolds fixed. The bridges can also be preconfigured in terms of their length dimensions and offered as accessories to the distribution block. The installer has the advantage that the bridge is directly usable, and that unlike a bridge made of a piece of cable no attention must be paid to a proper cutting, a right bend, etc., so that electrically conductive connections between two or more distribution blocks can be produced quickly and with little effort.

FIG. 1 shows a perspective view of an exemplary embodiment of a distribution block, designated overall by 10. The distributor block 10 has two connection points, namely a first connection point 14 and a second connection point 16, on an input or connection side 12. The two connection points 14, 16 are arranged one above the other in different planes. Both connection points 14, 16 independently allow the detachable connection of an electrical conductor (not shown), with the distribution block 10, an electrical potential or an electric current can be supplied to the or over on an output side 18 of the manifold block 10 in itself known manner connectable electrical conductors (also not shown) are distributed, ie other electrical equipment or units especially for their supply of electrical energy can be supplied.

In the illustrated embodiment, a circular insertion opening (first insertion opening) 20 is provided for the first connection point 14, and a rectangular insertion opening (second insertion opening) 22 is provided for the second connection point 16. The circular insertion opening 20 allows the connection of round conductors on the manifold block 10. The rectangular insertion opening 22 allows the connection of flat conductors. The potential to be distributed or the current to be distributed can thus be supplied to the distributor block 10 optionally with an electrical conductor in the form of a round conductor or with an electrical conductor in the form of a flat conductor.

FIG. 2 shows the distributor block 10 from FIG. 1 in a sectional illustration with a vertical sectional plane along the longitudinal axis of the distributor block 10.

The input or connection side 12 is in the illustration on the left and corresponding to the output side 18 right. Inside a housing of the distribution block 10 is a clamping body 24 which extends within the housing from the input side 12 to the output side 18. The housing is a housing with basically known function. It resets the live parts in the connected state, that is to say in particular the clamping body 24 and conductive parts in contact therewith, from a surface of the distributor block 10 and thus ensures contact protection. Furthermore, the housing for holding and adjusting at least the clamping body 24 is effective and thus at least indirectly for holding and adjusting all connected to the clamping body 24 components.

Finally, the housing is designed with a view to a handy and attractive design suitable.

The clamping body 24 has, in the region of the first connection point 14 and as a contact point for an electrical conductor which can be fed in here, a bore which is referred to below as a round conductor insertion bore 26 in order to distinguish it. Above the Rundleitereinführbohrung 26 is located in the clamping body 24 has a bore for a clamping screw (not shown) for fixing an inserted into the Rundleitereinführbohrung 26 electrical conductor (not shown). This bore is referred to as Rundleiterklemmschraubenbohrung 28 to distinguish.

On its output side 18, the distributor block 10 and its clamping body 24 in a manner known per se on the output side connection points for tapping the respective supplied potential. The output-side connection points are arranged in several levels, here three levels. The clamping body 24 has for this purpose a step profile. It is understood that a potential applied to the clamping body 24 at the round conductor insertion bore 26 by the local connection of an electrical conductor can be picked up at each output-side connection point.

Below a bottom 30 of the clamping body 24 in the region of the second connection point 16 is a fixing element 32. The fixing element 32 is movable against the underside 30 of the clamping body 24. In the illustrated configuration, a gap remains between the underside 30 of the clamping body 24 and the fixing element 32. In this space, an electrical conductor can be inserted at the second connection point 16. By the fixing member 32 is movable against the bottom 30 of the clamping body 24, the gap can be reduced, so that in a progressive movement of the fixing member 32 in the direction of the bottom 30 of the clamping body 24 finally a two-sided contact of the electrical conductor (not shown) on the one hand with the underside 30 of the clamping body 24 and on the other hand with an upper side of the fixing part 32 results. With then further advancing movement of the fixing member 32 in the direction of the underside 30 of the clamping body 24, an electrical conductor supplied to the second connection point 16 is fixed in the distributor block 10.

The underside 30 of the clamp body 24 acts as a stop. By virtue of the fact that the clamping body 24 itself acts as a stop, as soon as a conductor inserted at the second connection point 16 is permanently connected to the stop / clamping body. 24 comes into contact, made an electrically conductive contact with the clamping body 24, so that the supplied at the second connection point 16 potential on the output side 18 of the manifold block 10 can be tapped in a conventional manner.

FIG. 3 shows the distributor block 10 in a sectional view and in the same perspective as FIG. 1. In the illustration in FIG. 3, a sectional plane runs approximately centrally through the housing, ie, as shown in the side view in FIG. However, the cut also covers only the housing, so that in terms of the clamping body 24, the view of the front side, top and side surface and partly its stepped back is free.

In the clamping body 24 can be seen the Rundleitereinführbohrung 26 and the Rundleiterklemmschraubenbohrung 28. Right and left of the Rundleiterklemm- screw hole 28 (only visible on one side), the clamping body 24 has a recess and then a bore, which in the following to distinguish as Fixierelementhalteschraubenbohrung 34th referred to as. The fixing element 32 itself has two holes, namely threaded holes, which are in continuation of an axis defined by the Fixierelementhalteschraubenbohrungen 34.

FIG. 4 shows a perspective view of a further sectional illustration of the distributor block 10 with a sectional plane along the outside of the clamping body 24 as in FIG. 3. In addition to the aspects already shown in FIG. 3, a screw introduced in one of the fixing element holding screw bores 34 is shown for distinction as Fixierelementhalteschraube 36 is designated. The recess of the fixing element retaining screw bore 34 in the clamping body allows the recessed insertion of a

Screw head of Fixierelementhalteschraube 36.

The Fixierelementhalteschraube 36 is in a conventional manner with a tool, so for example a screwdriver (not shown) operable. The actuation takes place from an upper side of the distributor block 10. The same applies to a clamping screw which is not visible in the drawing and is inserted into the round-head clamping screw bore 28 and held in a thread there. Such a clamping screw and the or each Fixierelementhalteschraube 36 are examples of on an upper side of the manifold block 10 or from an upper side of the manifold block 10 accessible means for independent actuation of the first and second connection point 14, 16. The or each Fixierelementhalteschraube 36 on the one hand and a clamping screw on the other separately accessible from the top or at the top of the manifold block 10. Both can be operated independently of each other, so that the actuation, for example, of the clamping screw in the Rundleiterklemmschrauben- bore 28, the second connection point 16 is unaffected.

With an actuation of the Fixierelementhalteschraube 36 increases in the housing of the manifold block 10 rotatably mounted fixing element 32 on the thread or at least one at the free end of Fixierelementhalteschraube 36 sections formed thread. This rising is referred to here as movement of the fixing part 32 against the underside 30 of the clamping body 24.

The two block arrows drawn in FIG. 4 illustrate the different directions relevant to the actuation of the fixing element retaining screw 36. On the one hand, the upper, downwardly directed block arrow clarifies the actuating direction of the or each Fixierelementhalteschraube 36. On the other clarifies the lower, in the illustration, upward block arrow the direction of movement of the fixing member 32 upon actuation of the or each Fixierelement- holding screw 36 for connecting an electrical Conductor at the second junction 16. It can be seen that the direction of actuation and direction of movement of the fixing member 32 are opposite to each other. A fixing element holding screw 36 mounted in the clamping body 24 or, as shown here, a configuration with two fixing element holding screws 36 is thus an example of means for moving the fixing part 32 against the actuating direction of the respective means and towards the clamping body 24. In the case of fixing element holding screws 36 the movement against the direction of actuation and in direction on the clamping body 24, the rise of the rotatably mounted fixing part 32 on the thread of the two Fixierelementhalteschrauben 36th

Already in FIG 2 it was seen that the distribution block 10 in the illustrated embodiment has a bottom profile for releasably connecting to a mounting unit, for example, a known DIN rail (not shown). As a bottom profile, a first side of a bottom surface of the distributor block 10 can be seen in the sectional view, which is designed at least in sections as a rigid hook 38. On a second side of the bottom surface of the distributor block 10 opposite the rigid hook 38 there is a resilient hook 40. The rigid hook 38 is used to mount the distributor block 10 on a DIN rail. The distributor block 10 is then pivoted until the resilient hook 40 comes into engagement with the profile of the DIN rail. As soon as the resilient hook 40 engages behind the profile of the DIN rail, the distributor block 10 is releasably locked to the DIN rail. To release the locking of the resilient hook 40 is deflected in a conventional manner with a tool until it comes out of engagement with the profile of the top hat rail. Then the distributor block 10 can be released from the DIN rail. It was already apparent in FIG. 1 that the distributor block 10 in the illustrated embodiment has a rowable side profile. Dovetail-shaped positive-locking elements are shown as an example of a rowable side profile. 1, the positive-locking element is a dovetail-shaped form-fitting receptacle 42 in the form of a recess recessed from the surface of the side surface with a dovetail-shaped profile. On the opposite side surface is located as a positive locking element 44 has a corresponding structure, which rises with schwalbenschanzförmigem profile over the surface of the side surface. Such a structure can be introduced into the corresponding recess of another distributor block 10 by translatory movement. For an even more reliable combination of two manifold blocks 10 with the form-locking elements 42, 44 may be provided when producing the positive connection locking connection, for example by a on a projection formed on one side surface of the distributor block, for example a vertical bar, and a corresponding recess in the other side surface (not shown). 5 shows the distributor block 10 from its output side 18. It can be seen that the distributor block 10 has, in a manner known per se, several rows one above the other in several levels, each with a plurality of output-side connection points for forwarding a potential that can be tapped there. The output-side connection points can, as shown here, be designed as screw terminals. Other terminal types, such as spring terminals, are additionally or alternatively also possible. Moreover, the illustration in FIG. 5 shows a configuration of a distributor block 10, in which individual output-side connection points allow the insertion of an electrical conductor with a larger cross-section, namely in the illustration the two output-side connection points arranged in the lower level. Furthermore, it can be seen that individual output-side connection points have a collar as touch protection and for increasing an electrically effective distance to an adjacent connection point. Furthermore, it will be appreciated that apertures formed in the housing to permit one tool to actuate a respective clamping screw for use with one of the output-side terminals are each arranged to be relative to a series of output-side terminals in the above lying each level in front of a bridge between two output-side connection points. This reduces the risk of coming in contact with live parts when slipping off with the tool. In addition, this arrangement of the openings in the housing allows actuation of the clamping screw each individual output-side connection point, even if the respective outgoing in the same plane output-side connection points are each contacted with electrical conductors. The openings for actuating the clamping screws remain accessible in this alternating arrangement between two adjacent conductors.

6 shows a system with two distributor blocks 10 (a combination of two distributor blocks 10). The combination is using the form-locking elements 42, 44 produced. Otherwise, the combination of two or more distribution blocks 10 may also result from their attachment to a mounting unit, for example a DIN rail (not shown). When using the form-locking elements 42, 44 for producing a system comprising a plurality of distributor blocks 10, the combination is first of all carried out via the form-locking elements 42, 44 and the dressing thus formed is attached in its entirety to the assembly unit. This has the advantage that both movement processes require different directions of movement. The combining by means of the form-locking elements 42, 44 requires a translational movement. Combining with the mounting unit requires a rotational movement. The combination via the form-locking elements 42, 44 can thus not be solved again in a dressing thus formed and attached to a mounting unit. To disassemble the dressing, removal from the assembly unit is first required. Moreover, with a dressing formed over the interlocking elements 42, 44, it is not possible to move a single distributor block 10 along the assembly unit. The distances between two combined manifold blocks thus always remain the same on the mounting unit, even if a complete bandage is possibly displaced along the mounting unit. In the system of distributor blocks 10 shown in FIG. 6, one of the distributor blocks 10, hereinafter referred to as first distributor block 10 ', is supplied with electrical current via an electrical conductor in the form of a round conductor 46 at the first connection point 14. Between the second connection point 16 of the first distributor block 10 'and the second connection point 16 of the adjacent, lined-up distributor block, which is referred to as the second distributor block 10 ", a flat conductor 48 runs as a bridge. The potential supplied via the circular conductor 46 is thus not only at all output-side connection points of the first distributor block 10 'but also at all output-side connection points of the second distributor block 10 "tapped bar.

It has already been apparent in FIG. 1 that the circular insertion opening 20 of the first connection point 14 is connected to the housing of the distributor by means of predetermined breaking points. Block 10 connected plate is hidden. The plate is integrally connected to the housing via the predetermined breaking points and remaining webs or the like and can be removed by utilizing the predetermined breaking points with little effort from the circular insertion opening 20. To connect the round conductor 46 at the first connection point 14 of the first distribution block 10 ', the local plate has been removed. The plate is still located in front of the circular insertion opening 20 of the first connection point 14 of the second distributor block 10 "The plate thus prevents any possibility of contact with the clamping body 24 arranged in the housing. The plate thus makes the distributor block 10 in the region of the circular insertion opening In the area of the second connection point 16, a corresponding safety is achieved by, for example, taking care when using the distributor blocks that the fixing element 32 rests against the underside 30 (FIG. 4) of the clamping body 24. In addition, in comparison with FIG The first connection point 14 also has an inherent finger safety of the second connection point 16, because while the round contour of the insertion opening 20 acting as the first connection point 14 and its comparatively large diameter still permits the insertion of a finger, this is the case with the rectangular and comparatively flat K ontur the second insertion opening 22 is not given. In principle, the second insertion opening 22 can be closed with a removable plate just like the first insertion opening.

7 shows a system with three distributor blocks 10. It can be seen that the looping through of a supplied potential with an alternating sequence of bridges takes place in the form of round and flat conductors 46, 48. The bridges may be prefabricated round and flat conductor pieces 46, 48, after the distance between two adjacently arranged distributor blocks 10 and thus the distance between the respective connecting points, ie either the two first connection points 14 or the two second connection points 16, known and is constant.

In the illustrated embodiment of the distributor block, this has a width of 38 millimeters to a cross section of the supplied round conductor shown in the same scale with 120mm2. The circular insertion opening 20 of the first connection point 14 accordingly has a diameter of approximately fifteen millimeters. An arrangement of two circular insertion openings with these diameters next to each other in the same plane is not possible on the input or connection side 12, because the width of the clamping body 24 is due to the side walls of the housing, of course, less than the width of the manifold 10 in total and thus is of an order of magnitude from about thirty-four to thirty-five millimeters. The introduction of holes, each with a diameter of fifteen millimeters is not possible with sufficient wall thicknesses. Although an arrangement of a plurality of circular insertion openings in different planes is possible, the possibility of using simple, prefabricated bridges, as shown in FIG. 6 and FIG. 7, is then dispensed with if the height sections occupied by the insertion openings overlap on the connection side 12. If two circular insertion openings are arranged in different planes without such an overlap on the connection side 12, basically simple and prefabricated bridges of the type shown in FIG. 6 and FIG. 7 can be used. However, then eliminates the advantage of the usability of the manifold block 10 for both incoming conductor with round as well as with rectangular cross-section.

Further dimensions for a distribution block 10 for supplying currents of the order of 160 amperes, 250 amperes and 400 amperes are circular insertion openings 20 with twelve, fifteen or nineteen millimeters diameter for incoming strip with a conductor cross section of 70 mm ² , 120 mm ² resp 185 mm ² . For other currents there are correspondingly adapted dimensions.

The present invention relates to a distributor block 10 having at least one connection side 12 and a first and second connection point 14, 16 provided there, wherein the first and second connection point 14, 16 detachable connection of an electrical conductor ben, and with a against a bottom 30 of a clamp body 24 as the location of the first junction 14 movable fixing member 32 and a gap between a stop and an upper side of the fixing member 32 remaining space as a location of the second connection point 16, wherein for the second connection point 16 is a rectangular insertion opening 22 comes for connection of flat conductors into consideration.

FIG. 8 finally shows an alternative embodiment variant of the distributor block 10 from FIG. 1. The difference between the two embodiments consists in the arcuate housing edge between a housing base substantially accommodating the clamping body 24 and an upper housing part closing off the distributor block 10 at the top. Such a shape of the housing edge gives the distributor block 10 overall and especially also in cooperation with the rear side or exit side 18 which is curved in the lateral plan view (see FIG. 2) and the likewise arcuate upper side, an attractive optical apprehension. In addition, the distribution block sits so well in the hand and the edge-free or substantially edgeless surface avoids injuries. The arcuate transition between the lower housing part and the upper housing part engages the edge-free side contour of the distributor block 10 and leads to almost organic forms. In addition, the most downwardly projecting part of the upper housing part, where the lower housing part as it were recessed groove-like acts as a natural axis of rotation for the upper housing part, for example when this is combined after insertion of the clamp body 24 with the lower housing part.
