Description

Honeycomb assembly

The application is a divisional application of PCT patent application 'honeycomb assembly' (application number: 201680021190.2, applicant: phoenix electric company) entering China at 10 months and 10 days in 2017.

Technical Field

The invention relates to a honeycomb assembly (Wabenbaustein) for producing a power distribution honeycomb (Rangierwabe), comprising a box-shaped housing having two end faces and four side faces, which extend between the end faces, wherein each of the two end faces has at least one connecting region.

Background

The honeycomb assembly is used for connecting electrical lines to electrical devices or for connecting electrical lines to one another. For this purpose, coupling elements, which are usually connected to one another via corresponding busbars, are arranged in the box-shaped housing of the honeycomb assembly, so that electrical conductors which are introduced through conductor insertion openings in the front face can be electrically connected to electrical conductors or coupling contacts (Anschlusskontakt) which are introduced through insertion openings in the rear face of the housing. As the coupling element, in particular a clamping spring is used, by means of which the insulated conductor introduced through the conductor introduction opening is pressed against the busbar. The honeycomb assemblies are therefore electrical coupling terminals (Anschlussklemme), which, however, unlike electrical series terminals (Reihenklemme), are usually not latched onto a busbar but are used as part of a power distribution honeycomb made up of a plurality of honeycomb assemblies.

The distribution honeycomb is used in particular at locations where a plurality of electrical conductors must be connected in the most compact space. For this purpose, power distribution honeycombs are known from practice in which, inside a fixed rectangular assembly frame, a plurality of honeycomb assemblies are arranged in corresponding cavities of the frame. The electrical conductors can be coupled not only from the front side, the field side (Feldseite), but also from the rear side, the device side (analgenseite) to the distribution cells or individual cell assemblies.

An electrical connection terminal which can be used as a honeycomb module, for example for electrical distribution in rail vehicle technology, is known from DE 102013101830 a 1. Fig. 7 and 8 of this printed document show two different assembly frames or distributor housings, in each of which a predetermined number (18 or 54) of chambers are formed in a matrix, in each of which a honeycomb arrangement with two conductor insertion openings in the front end face is arranged. In this known power distribution honeycomb part, the production of the individual honeycomb assemblies is to be simplified in that the housing has a main housing part and a housing closure part, so that the contact inserts with the coupling elements can be inserted simply through the assembly openings in the main housing.

Distribution honeycomb parts with a plurality of honeycomb assemblies are also known from DE 19512226 a 1. In the power distribution honeycomb unit disclosed in this printed document, the individual honeycomb units are also inserted into the cavities of the power distribution honeycomb unit, wherein all honeycomb units have the same size and the same number and size of conductor lead-in openings. At its upper and lower edge sides, the distribution honeycomb parts each have a fastening flange projection, by means of which the distribution honeycomb parts can be fastened to the assembly frame by means of threaded fasteners. Additionally, the terminal module can be mechanically fixed at the fixing flange projection by means of a dovetail connection, wherein an electrical connection to the metal fitting frame can be realized by means of a contact plate inserted in the bottom of the terminal module. If the number of conductors to be connected has to be increased, correspondingly larger distribution cells with a greater number of individual cell assemblies have to be used, wherein distribution cells with 18,32,48,54 or 80 cell assemblies are available in practice.

Disclosure of Invention

The object of the invention is to provide a honeycomb assembly for use which can be connected in a simple manner to other honeycomb assemblies and can therefore be used together with the other honeycomb assemblies as part of a power distribution honeycomb.

In the case of the electrical distribution honeycomb element according to the invention, this object is achieved in that at least one side has at least one tongue and at least one corresponding groove is formed in the opposite side for connection with a tongue of another honeycomb structure, and in that a connecting element is formed at the at least one tongue and a corresponding mating connecting element is formed at the at least one groove.

The power distribution honeycomb structure according to the invention allows firstly greater flexibility in the arrangement of the power distribution honeycomb structure, in that the honeycomb structure can be connected directly to other honeycomb structures of corresponding design, so that the use of rigid assembly frames which determine the number of individual honeycomb structures can be dispensed with. The connection of the individual honeycomb assemblies is achieved here in that a tongue, which is formed on the side of a first honeycomb assembly, is pushed into a corresponding groove in the side of a second honeycomb assembly, i.e. by a groove-tongue connection. In this way, power distribution cells with any number of cell assemblies can be constructed, so that the size and in particular the number of poles (Polzahl) of the power distribution cells can be adapted to the respective requirements and, if possible, also simply changed. Such a distribution honeycomb, or a honeycomb assembly of similar design, is known from the document DE 102014101528 a1, which is published subsequently.

In the honeycomb assembly according to the invention, the mechanical fixing to the adjacent honeycomb assembly is further improved by the connecting elements being configured at the tongues and the grooves having corresponding mating connecting elements. The mechanical fastening between the two honeycomb assemblies is thereby achieved not only by the groove-tongue connection, but additionally also by the connecting element and the mating connecting element, wherein the connecting element is formed at the tongue and the mating connecting element is formed at the groove, so that the space requirement for the second connection form is not increased or only slightly increased.

According to an advantageous embodiment of the honeycomb assembly according to the invention, the tongues and grooves each have a dovetail-shaped cross section, so that at least one tongue is a dovetail and at least one groove is a corresponding dovetail groove. The mechanical connection formed by the dovetail and the dovetail groove has the advantage that it can be simply assembled and disassembled and can nevertheless withstand relatively high forces. Nevertheless, in mechanical connections formed solely by the dovetail and the dovetail groove, there is the risk that the dovetail and the groove may slip off of each other in the event of a rotational or tilting movement of one of the two components. This is prevented in the honeycomb assembly according to the invention by additionally also providing connecting elements and corresponding mating connecting elements.

Preferably, at least one tongue or at least one groove is formed on each of all four sides of the honeycomb structure, so that the honeycomb structure can be connected to another honeycomb structure both in the x-direction and in the z-direction. In principle, it is also possible to form both the at least one tongue and the at least one groove on a single side.

In a power distribution honeycomb structure composed of a plurality of honeycomb assemblies, the stability of the power distribution honeycomb structure can be further increased by the longitudinal extent of the at least one spring on the first side deviating from the longitudinal extent of the at least one spring on the other side, wherein the deviation is preferably 90 °. In a honeycomb assembly, for example at a first side, the tongues may extend perpendicular to the longitudinal direction of the honeycomb assembly and at a second side having an angle of 90 ° with respect to the first side, the tongues are arranged parallel to the longitudinal direction of the honeycomb assembly. In this way, both a form fit and a force fit can be achieved between the interconnected honeycomb assemblies in the x direction and in the z direction.

In particular, there are now a number of possibilities, as are the connection elements formed at the tongues and the corresponding mating connection elements. The connecting element and the mating connecting element can likewise be designed as a tongue-and-groove connection. Alternatively, the connecting element and the mating connecting element can also form a snap-lock connection.

According to a first advantageous embodiment, the tongue has a projecting bridge at its front end in the mounting direction, against which bridge a recess corresponding to the bridge is formed in the housing at the end of the groove corresponding to the tongue. The bridge, which is formed at the tongue and can also be referred to as a pin, thus has the function of a plug and the recess has the function of a groove corresponding to the plug. This type of design of the tongue and groove prevents the tongue and groove from sliding off one another by a pivoting or tilting movement. Alternatively to the formation of the bridge at the front end of the tongue and the formation of the recess at the end of the groove, it is also possible to form the bridge at the end of the groove and the recess in the tongue, so that the bridge engages into the recess in the tongue when the tongue is pushed into the groove.

In an alternative embodiment, in which the sliding of the tongue and groove off one another due to the rotational movement is likewise prevented, the tongue has a rear section in the assembly direction with a greater width and the corresponding groove has a front section with a correspondingly greater width. If the tongue is pushed completely into the groove, the section of the tongue with the greater width is located in the section of the groove which is likewise widened. The widening on both sides of the tongue corresponds in each case to a plug which engages in the corresponding groove. In order to further reduce the risk of the groove and the tongue slipping off from each other, the two embodiments described above can also be combined with each other, i.e. the tongue can have a projecting bridge at its front end in the assembly direction and a rear section in the assembly direction with a greater width. Correspondingly, a recess corresponding to the bridge is formed in the housing at the end of the groove, and the groove furthermore has a front section with a greater width.

As already explained above, both a tongue-and-groove connection and a snap-lock connection can be realized between the connecting element and the mating connecting element. The tongue then has a latching element, and the groove is connected to a mating latching element. In an advantageous embodiment of this type of detent connection, the tongue has a detent or detent hook at its front end in the mounting direction. At the end of the corresponding groove, a latching recess corresponding to the latching pin or a latching opening corresponding to the latching hook is formed in the housing. If the tongue is pushed completely into the groove in this type of embodiment, the detent pin can engage in the detent recess or the detent hook can engage in the detent opening, as a result of which unintentional release of the two honeycomb assemblies connected in this way counter to the assembly direction is prevented.

If the tongue has a snap-in hook, this can be configured, as described above, at the front end of the tongue. However, it is also possible to form the latching hook at another point on the tongue with respect to the longitudinal extent of the tongue. For example, the latching hook can be formed at the rear end of the tongue in the mounting direction or in the central region. If the latching hook is located in the center region of the tongue, wherein a latching recess corresponding to the latching hook is also formed in the center region of the groove or a latching opening is formed in the housing, a latching connection which can only be released with great difficulty or even completely cannot be achieved in this way.

According to a last advantageous embodiment of the honeycomb assembly according to the invention, which is also to be explained briefly here, the tongue has two latching hooks at its front end in the assembly direction, which hooks point in opposite directions. In this embodiment, corresponding latching recesses are formed in the housing laterally to the longitudinal extent of the groove at the ends of the corresponding groove. If the spring is pushed completely into the groove, the two latching hooks engage in latching recesses in the housing which are laterally adjacent to the groove, so that the spring is reliably prevented from being pulled out of the groove counter to the assembly direction.

Detailed Description

Fig. 1 shows an exemplary embodiment of a honeycomb package 1, which honeycomb package 1 has a box-shaped housing 2 with two end faces 3 and four side faces 4a,4b,4c and 4 d. Three connection regions 5, which are preferably designed as spring force terminal connections (federkraftklemmschuss), are provided on the front face 3 of the honeycomb assembly 2. The respective side faces 4a,4b,4c,4d each extend between two end faces 3 and are each arranged at an angle of 90 ° to the end faces 3. Thus, the honeycomb assembly 1 or housing 2 has a rectangular cross-section with a width B, a height H, and a length or depth T. In the case of the honeycomb assembly 1 shown, the dimension B × H × T is, for example, 12mm × 11mm × 30mm, wherein this dimension is by no means limiting.

For connection with the other honeycomb assemblies 1',1 ″, the honeycomb assembly 1 shown in fig. 1 has four dovetail-shaped tongues 6 at the side 4a, which tongues 6 are arranged at different positions at the side 4a, not only in the x-direction but also in the z-direction. In the case of the illustrated embodiment, the individual tongues 6 each have a longitudinal extent in the z direction, which corresponds to approximately 1/3 of the height H of the housing 2 of the honeycomb assembly 1. On the side 4c of the honeycomb units 1 opposite the side 4a, grooves 7 are formed corresponding to the tongues 6, which likewise have a dovetail-shaped cross section, so that two honeycomb units 1 can be connected to one another in the x direction by pushing the tongues 6 arranged on the side 4a of one honeycomb unit 1 into the grooves 7 formed on the side 4c of the adjacent honeycomb unit. Furthermore, two latching projections 8 are formed on the first side 4a, which interact with corresponding (not visible here) latching projections on the side 4 c.

At the upper side 4b of the housing 2, a groove 9 is formed, which extends over almost the entire depth T of the honeycomb assembly 1. Correspondingly to the groove 9, a tongue 10 is formed on the lower side 4d of the honeycomb structure 1, so that two honeycomb structures 1,1 'can also be arranged one above the other in the z-direction by pushing the tongue 10 on the lower side 4d of the upper honeycomb structure 1' into the groove 9 on the upper side 4b of the lower honeycomb structure 1. In addition, two latching projections 11 are formed on the bottom side 4d of the housing 2, which interact with two latching projections 12 formed on the top side 4b and thus make an unintentional release of the two interconnected honeycomb assemblies 1,1' difficult.

In fig. 2, a groove-tongue connection is schematically shown between a tongue 6 arranged on the first side 4a of the first honeycomb package 1 and a groove 7 formed in the opposite side 4c of the second honeycomb package 1'. Fig. 2a shows the tongue 6 and the groove 7 in the separated state, while fig. 2b shows the tongue 6 and the groove 7 in the connected state. In this case, it can be seen from the illustration in fig. 2 that both the tongue 6 and the groove 7 each have a dovetail-shaped cross section. In the case of the groove-tongue connection shown in fig. 2, which is formed only by the dovetail 6 and the dovetail groove 7, there is the risk that the tongue 6 and the groove 7 can slip off relative to one another during a rotational or tilting movement of the two components. This is prevented in the honeycomb assembly according to the invention by the connecting elements and corresponding mating connecting elements being provided in addition to the tongues 6 and grooves 7, as explained in more detail below in accordance with the schematic illustration of the connection according to the invention.

Fig. 3 shows a schematic view of a first exemplary embodiment of the connection according to the invention between a tongue 6 and a groove 7. Here, a tongue 6 (also like the honeycomb package 1 shown in fig. 1) is formed on the first side 4a of the housing 2 of the first honeycomb package 1, so that the tongue 6 can be pushed into a groove 7 formed on the second side 4c of the second honeycomb package 1'. Although the first honeycomb structure 1 is also formed with a corresponding groove 7 on the side 4c opposite the first side 4a, the mechanical connection shown schematically in fig. 2 to 8 is always realized between the two honeycomb structures 1,1 'to be connected to one another, so that the tongue 6 is formed at one honeycomb structure 1 and the groove 7 is formed at the other honeycomb structure 1'. In this case, it is common to the illustrations of the different exemplary embodiments shown in fig. 3 to 8 that at least one additional connecting element is formed in each case at the tongue 6 and that the grooves 7 each have at least one corresponding mating connecting element.

In the exemplary embodiment shown in fig. 3, the spring 6 has a projecting bridge 13 at its front end in the mounting direction R, which bridge 13 has the function of a plug. Here, the bridge 13 has a smaller thickness than the spring 6. At the end of the groove 7, corresponding to the bridge 13, a recess 14 is formed as an extension of the groove 7 in the housing 2, the bridge 13 engaging into the recess 14 when the tongue 6 is pushed completely into the groove 7. In fig. 3a, the tongue 6 and the groove 7 are shown in the not yet assembled state, while in the illustration according to fig. 3b the tongue 6 is pushed completely into the groove 7. Fig. 3c and 3d show the tongue 6 and the groove 7 in longitudinal section, respectively, wherein in fig. 3c the tongue 6 is not yet inserted into the groove 7, while in fig. 3d the tongue 6 is completely inserted into the groove 7, so that the bridge 13 also engages in the recess 14.

The groove-tongue connection shown in fig. 3 between the projecting bridge 13 and the recess 14 ensures that the tongue 6 cannot be unintentionally pivoted out of the groove 7 by tilting. The same principle of this tongue-and-groove connection can also be achieved by the fact that a bridge is formed at the end of the groove 7 and a corresponding recess is formed at the front end of the tongue 6, so that when the tongue 6 is pushed into the groove 7, the bridge formed at the groove 7 engages in the recess in the front end side of the tongue 6.

In fig. 4, an additional groove/tongue connection is likewise realized, by means of which the tongue 6 and the groove 7 are prevented from sliding off one another as a result of the rotational movement. In a similar manner to fig. 3, fig. 4a and 4c also show the tongue 6 and the groove 7 in the unassembled state, while fig. 4b and 4d show the joined-together state. In fig. 4a and 4b, the tongue 6 and the groove 7 are shown in perspective, while in the illustration according to fig. 4c and 4d, a part of the tongue 6 and the groove 7 is cut away parallel to the longitudinal extension.

In this exemplary embodiment, the spring 6 has a rear section 15 in the mounting direction R, which rear section 15 has a greater width than the remainder of the spring 6. Correspondingly, the groove 7 has a front section 16 with a correspondingly larger width. The widening of the groove 7 in the front section 16 therefore has the function of a groove for widening on both sides of the tongue 6, wherein the widening at the tongue 6 corresponds functionally to a plug. If the tongue 6 is pushed completely into the groove 7, the rear section 15 of the tongue 6 with the greater width is located in the likewise widened front section 16 of the groove 7. Furthermore, the tongue 6 has a stop 17, so that the maximum insertion distance of the tongue 6 into the groove 7 is also limited by the stop 17.

Fig. 5 shows schematically an exemplary embodiment of the connection between the tongue 6 and the groove 7, in which the tongue 6 has a latching pin 18 at its front end in the mounting direction R and a corresponding latching recess 19 is formed in the housing 2 at the end of the groove 7. Fig. 5a and 5b show the tongue 6 and the groove 7 in a state not yet connected to one another, wherein fig. 5a shows a perspective view. Fig. 5c shows an enlarged detail of the tongue 6 and the groove 7 in the connected state. If the spring 6 is pushed completely into the groove 7, the detent pin 18 latches into a corresponding detent recess 19 in the housing 2, thereby preventing the spring 6 from being unintentionally pulled out of the groove 7 counter to the assembly direction R.

In the exemplary embodiments of the connection according to fig. 6 to 8, an additional latching connection between the tongue 6 and the groove 7 is also realized. In the exemplary embodiment according to fig. 6 and 7, a catch hook 20 is formed in each case on the tongue 6, and in the completely inserted state of the tongue 6 in the groove 7, the catch hook 20 engages in a catch opening 21, which catch opening 21 is formed in the housing 2 and is connected to the groove 7. In the exemplary embodiment according to fig. 6, the latching hook 20 is arranged approximately centrally in the longitudinal direction of the tongue 6, so that a corresponding latching opening 21 in the housing 2 is also arranged centrally with respect to the groove 7. If in this exemplary embodiment the detent opening 21 is not accessible from the inside of the housing 2, the detachment can only be effected if the inclined portion 22 is configured correspondingly at the detent hook.

In the exemplary embodiment according to fig. 7, a catch hook 20 (similar to catch pin 18 in the exemplary embodiment according to fig. 5) is formed at the front end of tongue 6. If, in the assembled state of the tongue 6 and the groove 7, the end of the latching hook 20 projects out of the latching opening 21, there is the possibility of releasing the latching again with the tip of a tool, for example a screwdriver, so that the tongue 6 can be pulled out of the groove 7 again counter to the assembly direction R.

Fig. 8 schematically shows an exemplary embodiment of the connection between the tongue 6 and the groove 7, in which the tongue 6 has latching hooks 23 at its front end 2 in the mounting direction R, which latching hooks point outward in the opposite direction. At the end of the slot 7, laterally adjacent to the slot 7, two latching recesses 24 are formed in the housing 2, into which latching recesses 24 the two latching hooks 23 engage when the tongue 6 is pushed completely into the slot 7. By means of the additional formation of the wedge 25 at the housing 2, which projects into the end of the groove 7, the snap-in hook 23 is prevented from springing back in the assembled state of the tongue 6 in the groove 7, so that in this exemplary embodiment, the detachment, i.e., the pulling-out of the tongue 6 from the groove 7 counter to the assembly direction, is no longer possible.

Fig. 9 shows an exemplary electrical distribution honeycomb made up of (only) three

honeycomb assemblies

1,1',1 ″ according to fig. 1, wherein the three

honeycomb assemblies

1,1',1 ″ are arranged one above the other in the z direction. In the illustration of the three

honeycomb assemblies

1,1',1 ″ according to fig. 9, the dovetail-shaped tongue 6 formed at the first side 4a is shown (as in fig. 1) without additional connecting means. Instead of the simple dovetail-shaped tongue 6 shown only in fig. 1 and in fig. 9, one of the embodiments of the tongue 6 shown in fig. 3 to 8 is arranged in the honeycomb assembly 1 according to the invention, for example on the side 4a of the housing 2, wherein corresponding grooves 7 are then formed in each case on the opposite side 4 c.

It can also be seen from the illustration of the honeycomb assembly 1 according to fig. 1 and 9 that the longitudinal extension of the spring 6 at the first side 4a deviates by 90 ° from the longitudinal extension of the spring 10 at the side 4 b. Correspondingly, the longitudinal extension of the groove 7 at the side 4c is also offset by 90 ° from the longitudinal extension of the groove 9 at the side 4 b. This achieves that, in a power distribution cell having a plurality of

cell assemblies

1,1',1 ″ which are connected to one another both in the x direction and in the z direction, the stability of the power distribution cell is increased, since then the fixing of the power distribution cell in all directions is only achieved by the orientation of the

different pins

6,10 at the

different sides

4a,4 b.
