Description

Honeycomb structural member

Technical Field

The invention relates to a honeycomb structure (Wabenbaustein) for forming a honeycomb array (Rangierwabe), comprising a box-shaped housing having two end faces and four side faces extending between the end faces, wherein at least two conductor insertion openings are formed in each of the two end faces, each of which is associated with a conductor connecting element arranged in the housing. The side faces each have at least one connecting element for connecting to a further honeycomb structure, wherein the connecting elements are designed and arranged corresponding to one another on the side faces lying opposite one another.

Background

Electrical series terminals (Reihenklemme) have been used for decades for connecting electrical conductors, which are usually clipped in a plurality side by side to a carrier rail (tragcschine), wherein the carrier rails equipped with series terminals in this way are often arranged in a switchgear cabinet. Instead of using a series terminal, a honeycomb arrangement is often used where a large number of electrical conductors have to be connected in the narrowest space, since relatively much space remains unused between the individual carrier rails.

It is known from practice to arrange honeycombs, in which a large number of honeycomb elements are arranged in corresponding chambers (Kammer) of a frame in a fixed, rectangular assembly frame. Electrical conductors can be connected to the arrangement cells or the individual cells from both the front side, the field side (feldsite) and the rear side, the contact side (antilagenesis). In this connection, conductor connection elements are arranged in the box-shaped housing of the respective honeycomb structure, which are usually connected to one another via corresponding busbars (Stromschiene), so that electrical conductors introduced through corresponding conductor insertion openings in the front end face can be electrically connected to electrical conductors or connection contacts (Anschlusskontakt) introduced through corresponding conductor insertion openings in the rear end face of the housing.

Such an arrangement honeycomb with a large number of honeycomb elements is known, for example, from DE 19512226 a 1. For the arrangement honeycomb disclosed in this document, the individual honeycomb members placed in the individual chambers of the arrangement honeycomb all have the same size. Fastening flange attachments (Befestights) are respectively formed on the upper and lower edge sides of the arrangement honeycomb, via which the arrangement honeycomb can be fastened to the mounting frame by means of screws. In this known arrangement, it is not possible to adapt the arrangement to the individual desires of the user. If the number of conductors to be connected has to be increased, a correspondingly larger array cell with a larger number of individual cells has to be used, wherein array cells with 18, 32, 48, 54 or 80 cells are in practice available.

DE 102014101528 a1 discloses a lining honeycomb which is characterized by increased flexibility and the possibility of adapting the lining honeycomb to the individual desires. This is achieved in that each side of the honeycomb structure has at least one connecting element for connecting to another honeycomb structure. The connecting elements which are formed on the sides which face one another are formed and arranged in such a way that they correspond to one another, so that the honeycomb structures can be directly connected to one another. The use of a rigid assembly frame for fixing the number of individual honeycomb elements can thus be dispensed with, so that the arrangement honeycomb can in principle have any number of honeycomb elements.

A similar arrangement of cells is also known from DE 202015101776U 1. The arrangement honeycomb is also formed from a plurality of honeycomb elements which can be connected to one another individually, and latching elements which correspond to one another are formed on the side faces of the honeycomb elements. Furthermore, various termination elements (absschlussel) are disclosed, which can be selectively fastened to one side of the arrangement of cells. For this purpose, the terminal element has mating latching elements (gegenstemement) which correspond to the latching elements of the honeycomb member. The terminal element can be used for fixing, for marking or for guiding the conductors to be joined.

If, in the arrangement honeycomb or honeycomb structure known from the prior art, individual honeycomb structures are to be connected to one another or individual connecting sections of the honeycomb structures are to be electrically connected to one another, the conductors must be connected to the conductor connecting elements to be connected. This then results in that, if two honeycomb parts are electrically connected to one another, a connecting contact of the honeycomb part is required for the connection, so that the number of conductor connecting elements available for use is correspondingly reduced by one each.

Disclosure of Invention

It is therefore an object of the present invention to provide a honeycomb structure in which the potential distribution can be carried out in a simple manner. In particular, it is to be possible here to make electrical connections between the two honeycomb parts simply and, if necessary, also afterwards.

This object is achieved in a honeycomb structure having the features of claim 1 in that at least two functional wells (functional wells) are formed in at least one end face of the honeycomb structure and at least two busbars are arranged in the housing of the honeycomb structure, wherein the busbars are each connected to the conductor connecting elements in an electrically conductive manner. In this case, the respective at least one opening in the busbar is formed in accordance with a functional well, so that a plug of a plug-in bridge (Steckbruecke) can be inserted through the functional well in the end face of the honeycomb component into the opening in the associated busbar. By simply inserting a plug-in bridge, which functions as a transverse bridge (querrbruecke), with two plugs into the functional wells of the honeycomb structure, it is possible to electrically connect two honeycomb structures, for example, arranged next to one another in a simple manner. The plugs via the plug bridges then electrically connect the busbars contacted by the plugs to one another, so that an electrical transverse connection between the two honeycomb structures is achieved.

At the beginning, at least two conductor insertion openings are formed in each case in the two end faces of the honeycomb structure, which are associated with a conductor connecting element arranged in the housing. In this case, the honeycomb structure then has a total of four conductor insertion openings, so that four conductor connecting elements are also arranged in the housing, wherein the conductor connecting elements associated with one another are connected to one another, for example via corresponding busbars, so that an electrical conductor inserted through a conductor insertion opening in the front end face can be connected to an electrical conductor inserted through an associated insertion opening in the rear end face of the housing via the first conductor connecting element, the busbars and the second conductor connecting element.

Of course, the honeycomb structure can also have more than two conductor insertion openings at both end faces, for example three, four, five, six or even more conductor insertion openings, so that a correspondingly greater number of conductor connecting elements is then also arranged in the housing. Preferably, a corresponding number of functional wells is then formed on at least one end face as many as the number of conductor insertion openings, and a corresponding number of busbars are also arranged in the housing, which are electrically connected to the conductor coupling elements and are accessible via the functional wells to the plugs of the plug-in bridge.

As already explained above, in the case of the honeycomb structure according to the invention, a transverse bridging (querberrueckung) between two adjacent honeycomb structures can be achieved in a simple manner by the formation of functional wells and correspondingly arranged busbars. By inserting the plug bridges with their plugs into the functional wells of the honeycomb structure, it is furthermore possible to electrically connect the conductor connecting elements of a honeycomb structure to one another by means of plug bridges with a corresponding number of plugs. In the case of the honeycomb structure according to the invention, therefore, not only can adjacent honeycomb structures be bridged laterally, but also the individual potentials of a honeycomb structure can be bridged.

According to a particularly preferred embodiment of the honeycomb structure according to the invention, the at least one functional well is dimensioned such that the two plugs of the two plug bridges can be inserted one after the other into the functional well in the direction of extent of the associated bus bar. This makes it possible to achieve both a transverse bridging between two adjacent honeycomb structures and a bridging of the individual potentials of a honeycomb structure by means of two corresponding plug bridges. The functional well therefore has a length corresponding to the width of the two plugs, so that the two plugs of the two plug bridges can be inserted one after the other into the functional well.

In order to be able to insert the two plugs of the two plug bridges not only into the functional well but also into contact with the bus bar associated with the functional well, the openings in the bus bar are dimensioned according to an embodiment variant of the invention such that the two plugs of the two plug bridges can be inserted into the openings one after the other in the direction of extension of the bus bar. The opening thus has a length corresponding to the width of the two plugs of the two plug bridges. Alternatively, two separate openings can also be arranged in succession in the busbar in the direction of extent of the busbar, so that the plug of one plug bridge can then be inserted into one opening and the plug of the other plug bridge into the other opening.

According to a further advantageous embodiment of the invention, the housing has a frame-like, hollow outer housing and at least two inner housings arranged next to one another therein. The connecting element for connecting the honeycomb structure to a further honeycomb structure is formed here at the outer housing. In each inner housing a conductor lead-through opening and the at least one functional well are constructed and a conductor coupling element is arranged. Preferably, the inner housing has a conductor insertion opening on the front side and a conductor insertion opening on the rear side, respectively, wherein then two electrically interconnected conductor coupling elements are also arranged in the inner housing. Such a design of the honeycomb structure has the advantage that the outer housing can be selectively combined with different inner housings. Depending on the diameter of the conductor insertion opening, it is thus possible, for example, to arrange not as many inner housings side by side in the outer housing. The inner housings designed as insertion elements each have their own electrical potential and can be connected fixedly to one another and to the outer housing via corresponding latching elements.

Although the inner housing has at least one conductor insertion opening (with a conductor connecting element associated therewith) both on its front side and on its rear side, it is in principle sufficient if a functional well is formed only on the front side or on the rear side. In principle, however, it is also possible to form functional wells both in the front side and in the rear side of the honeycomb structure or the inner housing, so that the plug-in bridges can be inserted into the honeycomb structure both from the front side and from the rear side (i.e. from the field side or from the contact side).

According to a further advantageous embodiment of the invention, a recess (aussapraung) is formed on at least one edge region of at least one end face, which recess is arranged adjacent to the functional well. As a result, it is possible for the conductor rails (Schienenleiste) of the plug-in bridges to be accommodated by the recesses or to be introduced into the recesses when two adjacent honeycomb structures are electrically bridged to one another via the plug-in bridges. This makes it possible for the inserted plug-in bridge to be formed with its guide rails not protruding beyond the end faces of the honeycomb structure. This reduces the risk of the plug bridges being unintentionally pulled out of the honeycomb structure or the individual conductors being difficult to connect to the conductor connection elements due to the plug bridges projecting from the honeycomb structure. If, according to a preferred embodiment, the honeycomb structure has an outer housing and a plurality of inner housings, the at least one recess is formed in the outer housing. In this case, recesses are preferably formed in each case at two edge regions lying opposite one another, so that the guide rails of the plug-in bridge can be introduced into the recesses on both sides when bridging transversely with the adjacent honeycomb structure.

In the honeycomb structure according to the invention, a retaining element is preferably formed on at least one edge region of the end face, which retaining element together with a corresponding retaining element of an adjacently arranged second honeycomb structure forms a retaining groove for a marking plate (Markierungsschild). In this way, individual cells or a comb constructed from a plurality of cells can be marked in a simple manner without additional terminal elements having to be attached to the comb. Furthermore, this offers the possibility of marking the individual honeycomb elements, since the marking plate can be arranged directly adjacent to the individual honeycomb elements.

In order not to increase the position requirement or the size of the individual honeycomb elements, rather than providing a separate retaining groove for the identification plate at each honeycomb element, the retaining groove is formed by two honeycomb elements arranged next to one another. Since the connecting elements for connecting to adjacent honeycomb structures are formed on the side faces of the honeycomb structures, a certain distance is always present between the connecting regions of two honeycomb structures arranged next to one another, which is therefore used as a fastening point for the identification plate. For this purpose, in each honeycomb structure, a retaining element is formed as part of a retaining groove at the edge region of the end face, i.e. at the transition region of the end face to the side face facing the adjacent honeycomb structure.

According to a further preferred embodiment of the invention, at least one groove and at least one web (Steg) associated with the groove are formed as connecting elements on each side of the honeycomb structure, wherein the respective groove and the respective web run parallel to the longitudinal extent of the respective side. Preferably, the webs and the grooves have a dovetail-shaped cross section, respectively, so that two such interconnected honeycomb elements can be displaced relative to one another perpendicular to the longitudinal extent of the grooves and webs. The at least one groove at the side faces of the honeycomb elements is arranged in mirror symmetry to the webs on the opposite side faces of the honeycomb elements, so that the webs at the side faces of one honeycomb element engage in the corresponding grooves at the opposite side faces of the other honeycomb element when two honeycomb elements are connected to one another. At the same time, the grooves at the side of one honeycomb element together with the webs at the opposite side of the other honeycomb element also form a corresponding mechanical connection. Between two interconnected honeycomb elements, there are then at least two connections, in particular at least two groove-spring connections.

By constructing at least one connecting element at all four sides of the honeycomb structure, wherein the connecting elements constructed at the sides lying opposite one another are constructed corresponding to one another, the honeycomb structure can be connected to further honeycomb structures both in the x direction and in the y direction and adjacent honeycomb structures of the arrangement honeycomb can be fixed relative to one another both in the x direction and in the y direction.

In order to secure the honeycomb structure to one another also in the z-direction, latching elements are preferably provided in the honeycomb structure, which latching elements are arranged on at least two sides of the honeycomb structure that adjoin one another. Due to the arrangement of at least one latching element at each of the two mutually adjoining sides of the honeycomb structure, the two honeycomb structures can also be fixed to one another in the z direction, irrespective of whether the second honeycomb structure is arranged next to the first honeycomb structure in the x direction or in the y direction.

The detent elements are preferably designed as detent lugs (Rastnase), so that the fastening or latching between two adjacent honeycomb parts is achieved by bringing the detent lugs of one honeycomb part into engagement with the detent lugs of the adjacent honeycomb part. For this purpose, the two honeycomb parts to be connected to one another are arranged so that they face one another with a side face at which the latching elements are formed in each case. In order to facilitate the sliding of the detent noses over one another (Vorbeigleiten), the side on which the detent noses are arranged is preferably designed to be elastic. Alternatively, the latching element can also be designed as a latching arm, at the free end of which at least one latching nose is arranged in each case.

In the arrangement of the honeycomb or honeycomb structure, preferably, a displacement of the two honeycomb structures relative to one another in the longitudinal extension (z direction) of the respective side is prevented in that two latching elements are respectively arranged at least two mutually adjoining sides of the honeycomb structure. The two latching elements are arranged next to one another, as viewed in the longitudinal extension of the respective side, the latching elements extending in opposite directions. Furthermore, the latching elements are constructed and arranged such that their ends slightly intersect in the longitudinal extension. If two honeycomb structures, in which two such latching elements are arranged on opposite sides, are connected to one another, this results in two latching element pairs of a total of four latching elements crossing in the middle of the sides of the honeycomb structure. A displacement of the two honeycomb elements connected to one another in this way parallel to the longitudinal extent of the two side faces lying opposite one another is then no longer possible, so that the two honeycomb elements are also reliably locked to one another in the z direction.

In addition to the honeycomb structures used for constructing the arrangement honeycomb, the invention also relates to an arrangement honeycomb with a plurality of interconnected honeycomb structures according to the invention. By configuring each honeycomb element with at least two functional wells, the possibility is provided for electrically conductively connecting a plurality of honeycomb elements to one another in an arrangement honeycomb.

In this case, a first embodiment according to the invention uses a plug bridge with two plugs, wherein the plugs of the plug bridge are inserted into the functional wells of two adjacent honeycomb parts, such that the two plugs of the plug bridge respectively contact the busbars in the honeycomb parts and are thereby electrically connected to one another. A plug-in bridge, as is known from the prior art, can be used here as a plug-in bridge. Such a plug-in bridge has in particular two plugs which are connected to one another via a guide rail, so that the plug-in bridge is of generally U-shaped design. In particular, the plug-in bridge in the region of the rail has an insulation head (isolerkopf) here, which also serves as a gripping section (Griffabschnitt) of the plug-in bridge. The individual pins of the plug-in bridge can be formed by parallel contact legs which are arranged next to one another, wherein preferably at least one of the contact legs is elastically designed such that the pin elastically contacts a corresponding opening in the busbar. Such plug bridges are known in principle, in particular for use in series terminals.

According to an alternative embodiment, the transverse bridging between two adjacent honeycomb components of the arrangement honeycomb is not realized by means of plug bridges but by means of U-shaped, electrically conductive connecting elements. The U-shaped legs of the connecting element are inserted into the functional wells of two adjacent honeycomb structures, so that the two U-shaped legs of the connecting element respectively contact the busbars in the honeycomb structures and are thereby electrically connected to one another. Such a connecting element can be very simply punched out of an electrically conductive flat material and bent over accordingly.

In the arrangement honeycomb according to the invention, either plug bridges or U-shaped connecting elements are used for transverse bridging between adjacent honeycomb structures, so that plug bridges with a plurality of plugs can preferably additionally be inserted into the functional wells of at least one honeycomb structure, wherein the plugs of the plug bridges electrically connect the busbars of the honeycomb structure to one another. Preferably, the honeycomb structure has a number of functional wells corresponding to the number of conductor insertion openings at the end faces and a corresponding number of busbars connected to the conductor connection elements, so that the entire electrical potential of the honeycomb structure can be connected to one another via a plug bridge with a corresponding number of plugs.

Detailed Description

The figures show two honeycomb structures 1 which are arranged laterally next to one another (fig. 1 and 2) or on top of one another (fig. 3) and thus form an arrangement honeycomb 2. In practice, such an arrangement honeycomb 2 usually has more than just two honeycomb structures 1, for example four, eight, sixteen or even more identical or different honeycomb structures. The individual honeycomb structures 1 can be arranged relative to one another such that each honeycomb structure 1 is connected to at least one further honeycomb structure 1 both in the x-direction and in the y-direction.

Each honeycomb structure 1 has a box-shaped housing 3 with two end faces 4a,4b and four side faces 5a,5b,5c and 5 d. In this case, the

respective side face

5a,5b,5c,5d extends between the two end faces 4a,4b and has an angle of 90 ° with respect to the end faces 4a,4 b. The honeycomb structures 1 thus have a substantially rectangular cross section, wherein the individual honeycomb structures 1 are currently even square in design and have the same dimensions, although the invention is not limited thereto. Furthermore, the honeycomb structure 1 has a length or depth which extends in the longitudinal extension of the respective side faces 5a,5b,5c,5d and thus in the z-direction, which is the same in the two honeycomb structures 1 shown. However, the invention is not limited thereto, i.e. the individual honeycomb structures can also have different depths.

At the front end face 4a of the honeycomb component 1, a plurality of conductor insertion openings 6 are formed, through which the conductors to be connected can be inserted into conductor connection elements 7 arranged in the interior of the housing 3. In the exemplary embodiment shown in the figures, the conductor connecting element 7 is designed as a clamping spring (Klemmfeder), so that the conductor connecting element 7 is a spring-loaded clamping contact (federkraftlemmanschluss). Alternatively, however, conductor coupling elements with other coupling techniques, for example, screw clamping (Schraubklemmen) or tension spring clamping, may also be used. The stripped conductor introduced into the housing 3 through the conductor insertion opening 6 is clamped in the illustrated honeycomb component 1 by means of clamping springs against a busbar connected to a second conductor connection element which is accessible through a conductor insertion opening formed on the rear side 4b of the honeycomb component 1.

In order to connect the honeycomb structures 1 to one another, the honeycomb structure 1 has a plurality of connecting

elements

8,9 at all four

sides

5a,5b,5c,5 d. In this way, a honeycomb structure 1 can be connected to another honeycomb structure 1 at all four

sides

5a,5b,5c,5d and thus not only in the x-direction but also in the y-direction, in order to form a corresponding arrangement honeycomb 2. In the exemplary embodiment shown in the figures, the honeycomb component 2 has, as connecting elements, at all four

sides

5a,5b,5c,5d, a dovetail-shaped groove 8 and a dovetail-shaped web 9, respectively. The grooves 8 at the side faces 5a,5b,5c,5d are arranged mirror-symmetrically to the webs 9 on the opposite side faces 5c,5d, 5a,5b, so that in two interconnected honeycomb structures 1 the grooves 8 and webs 9 of one side face 5a of one honeycomb structure 1 engage with the webs 9 and grooves 8 of the opposite side face 5c of the adjacent honeycomb structure 1.

Since both the grooves 8 and the webs 9 extend parallel to the longitudinal extent of the

respective side

5a,5b,5c,5d, the connection of the two honeycomb parts 1 to one another is achieved in that the honeycomb parts 1 are pushed into one another in the z direction with their respective opposing grooves 8 and webs 9, as is shown in fig. 4. The mounting direction therefore runs parallel to the longitudinal extent of the side faces 5a,5b,5c,5 d. The mounting direction also corresponds to the insertion direction of the conductor into the conductor insertion opening 6.

A plurality of functional wells 10 are formed in the end faces 4a of the two honeycomb structures 1, wherein the number of functional wells 10 corresponds to the number of conductor insertion openings 6 in the end faces 4a of the honeycomb structures 1. In the exemplary embodiment shown in the figures, in which five conductor insertion openings 6 are formed in the end face 4a of the honeycomb structure 1, there are also five functional wells 10, as can be seen in particular from fig. 1 b. Furthermore, a corresponding number of busbars 11, which are each connected in an electrically conductive manner to the conductor coupling element 7, are arranged in the housing 3 in the region of the functional well 10. As can be seen from fig. 7, the openings 12 in the bus bars 11 corresponding to the respective function wells 10 are each configured such that the plug 13 of the plug bridge 14 can be inserted through the function well 10 into the opening 12 in the corresponding bus bar 11.

As can be seen from fig. 2, the two interconnected honeycomb structures 1 are electrically connected to one another via a first plug bridge 14 having two plugs 13. In addition, a second plug bridge 24, which has five plugs 23, is inserted in each case into the two honeycomb structures 1. The individual plugs 13 of the plug-in bridge 14 or the two plugs 23 of the plug-in bridge 24 are connected to one another via a rail strip, wherein the rail strip is covered by the insulating

heads

15, 25.

In the exemplary embodiment of a honeycomb structure 1 according to the invention shown in the figures, the housing 3 has a frame-like hollow outer housing 16 and a plurality of inner housings 17 arranged side by side therein. In the present case, a total of five disk-shaped inner housings 17 are arranged next to one another in the frame-like outer housing 16, wherein in each inner housing 17 a conductor insertion opening 6 is formed on the front side and on the rear side and two conductor connecting elements 7 are arranged in the interior of the inner housing 17 in association with the conductor insertion opening 6. Furthermore, a functional well 10 is formed in each case in the front side of the inner housing 17, by means of which the bus bars 11 likewise arranged in the inner housing 17 are accessible. The respective inner housings 17 acting as insertion elements therefore have their own electrical potential (von Haus aus) in each case, i.e. they are not electrically connected to one another. As can be seen in particular from fig. 1b, the functional wells 10 of the inner housings 17 arranged side by side are arranged on a line running parallel to the edge of the end face 4 a.

As can be seen from fig. 2, 3 and 5 to 7, each function well 10 is dimensioned such that the two

plugs

13,23 of the two

plug bridges

14,24 can be inserted one after the other into the function well 10 in the direction of extension E of the associated bus bar 11. The functional well 10 thus has a length corresponding to the width of the two

plugs

13, 23. In order to allow both

plugs

13,23 of both plug

bridges

14,24 to contact the busbar 11, the opening 12 in the busbar 11 is dimensioned such that both plugs 13,23 can be inserted into the opening 12 one after the other in the direction of extension E of the busbar 11 (fig. 7). This provides the possibility of simultaneously achieving a transverse bridging between two adjacent honeycomb structures 1 via the first plug bridges 14 and a bridging of the respective potentials of the honeycomb structures 1 by means of the second plug bridges 24. The first plug bridge 14 here has only two plugs 13, while the second plug bridge 24 has a number of plugs 23, in the present case five plugs 23 (fig. 5), corresponding to the number of functional wells 10 of the honeycomb structure 1.

As can be seen in particular from fig. 2a and 6, the functional well 10 is designed in the end face 4a of the honeycomb structure 1 in such a way that the plug-in bridges 24 can be inserted into the functional well 10 in each case so far that the guide rails or insulation plugs 25 of the plug-in bridges do not project beyond the end face 4a of the honeycomb structure 1. In order to make this possible also in the plug-in bridges 14 which connect two honeycomb structures 1 to one another, recesses 18 are formed in each case at two mutually opposite edge regions of the end face 4a, which recesses are arranged adjacent to the functional well 10, so that the conductor rails or insulation heads 15 of the plug-in bridges 14 can be sunk into the recesses 18. The inserted plug bridges 14,24 then do not project beyond the end face 4a of the honeycomb structure 1.

It can also be seen from fig. 1 that retaining elements 19 are formed at the edge regions of the end faces 4a of the honeycomb structures, which together with corresponding retaining elements 19 of the adjacent honeycomb structure 1 form retaining grooves 20 into which the identification plates can be snapped. The holding elements 19 are preferably formed at all four edge regions of the two end faces 4a,4b, so that the respective marking tags can be fixed both on the front side and on the field side of the honeycomb structure 1 and on the rear side and on the contact side thereof. Furthermore, the marking plate can then be fixed selectively in the x direction and/or in the y direction at the honeycomb structure 1. It can also be seen from a comparison of fig. 2 and 3 that, depending on the arrangement of the honeycomb structure 1, a transverse bridging can also be realized in the x direction or in the y direction by means of the plug bridges 14, 24.

As can be seen from the illustration according to fig. 4, the individual honeycomb elements 1 are thus fixedly connected to one another in the x-direction and in the y-direction, and the individual dovetail-shaped webs 9 are inserted into the corresponding grooves 8. However, the movement of the honeycomb structure 1 relative to one another in the z direction is not impeded by the groove 8 and the web 9, since the groove 8 and the web 9 both extend parallel to the longitudinal extent of the

respective side

5a,5b,5c,5d and are not provided with a stop or edge which would limit the movement in the z direction. In order to prevent the individual honeycomb components 1 of the arrangement honeycomb 2 from moving relative to one another in the z direction, the honeycomb component 1 in the embodiment shown has two latching elements 21, each of which is designed as a latching nose, on its

respective side

5a,5b,5c,5 d.

The latching elements 21 each extend over the longitudinal extent of the

respective side

5a,5b,5c,5d, wherein the two latching elements 21 formed at the side are arranged next to one another over the longitudinal extent of the

respective side

5a,5b,5c,5d and extend in opposite directions. Since the ends of the latching elements 21 intersect in the longitudinal extension, the end of one latching element 21 is arranged slightly further back in the z direction and the end of the other latching element 21 is arranged slightly further forward.

Fig. 5 to 7 show how plug bridges 14 for transverse connection between the two honeycomb parts 1 can be inserted into two honeycomb parts 1 arranged next to one another (which are connected to one another via corresponding slots 8 and webs 9 and are additionally fixed to one another in the z direction via latching elements 21). In addition, plug bridges 24 can also be inserted into the two honeycomb structures 1, respectively, via which plug bridges 24 the individual conductor connection elements 7 in the individual inner housings 17 can be bridged.

It can be recognized by the expert that it is absolutely necessary to insert all three

plug bridges

14,24 into the two honeycomb structures 1. Instead, it is also possible to achieve a transverse bridging of two adjacent honeycomb structures 1 only via the plug bridges 14 or to insert only the plug bridges 24 into the honeycomb structures 1. In all possible variants, however, the individual conductor insertion openings 6 for connecting the individual conductors remain free, so that a maximum of five conductors can always be connected to the honeycomb structure 1 shown in the figures for each

end face

4a,4b, irrespective of whether a plug 13, two

plugs

13,23 or no plugs are inserted in the individual functional wells 10.

Fig. 8 shows an alternative embodiment of the two honeycomb structures 1 according to fig. 2 or 7, wherein the transverse bridging of the two honeycomb structures 1 is not realized via the plug bridges 14 but via the electrically conductive connecting elements 22. The connecting element 22 is of substantially U-shaped design, wherein the two U-shaped legs 26 of the connecting element 22 are inserted into the functional wells 10 of two adjacent honeycomb structures 1. The end of the U-shaped leg 26 of the connecting element 22 is bent in such a way that it runs parallel to the busbar 11. In addition, an opening 27 is formed in the end of the U-shaped leg 26, into which the plug 23 of the plug bridge 24 is inserted.

In the exemplary embodiment shown in fig. 8, the electrical connection of the U-shaped leg 26 of the connecting element 22 to the associated busbar 11 is thus respectively realized via the plug 23 of the plug bridge 24 inserted into the honeycomb structure 1. The U-shaped connecting element 22 can therefore be used as an alternative to the plug bridges 14 for laterally bridging two adjacent honeycomb structures 1, wherein the plug bridges 14,24 are then inserted into the two honeycomb structures 1 in order to reliably electrically contact the busbar 11 with the connecting element 22.
