Description

[Technical Field]

[0001] The present invention relates to a busbar unit, a module connection device including the busbar unit, and a connection device for connecting busbar units. [Background technology]

[0002] Busbar units, module connection devices with busbar units, and coupling devices for busbar units are known from the prior art. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved busbar unit, an improved module connection device comprising a busbar unit, and an improved coupling device for a busbar unit. [Means for solving the problem]

[0004] The object of the invention is achieved by the busbar unit, the module connection device and the coupling device of the independent claims. Advantageous embodiments are the subject of the dependent claims.

[0005] According to one aspect of the present invention, there is provided a busbar unit comprising: a busbar body; and a connection device for connecting the busbar body to a module connection element and / or a further busbar unit, the connection device having a connection body protruding from a connection end of the busbar body and having a first coupling end and a second coupling end opposite the first coupling end, the connection device being formed at the connection end of the busbar body via the first coupling end, the connection body including a coupling unit at the second coupling end for coupling the connection device to the module connection element and / or the further busbar unit, a coupling position of the connection device being defined by the coupling unit, and the coupling position of the connection device being variably aligned with respect to a translational direction and / or a rotational axis relative to the busbar body of the busbar unit.

[0006] This achieves the technical advantage of providing an improved busbar unit that allows tolerance compensation. For this purpose, the busbar unit comprises a connection device on the busbar body. The busbar body of the busbar unit can be connected via the connection device to module connection elements of the module connection unit and / or to further busbar units.

[0007] Here, the connection device is aligned such that when the busbar body of the busbar unit is connected to the module connection element and / or the further busbar unit via the connection device, the coupling position at which the connection device of the busbar unit is connected to the module connection element and / or the further busbar unit can be variably aligned along a translational direction and / or around a rotational axis relative to the busbar body.

[0008] This variable alignment of the coupling locations where the connection devices are connected to the module connection elements and / or further busbar units can compensate for installation tolerances and / or manufacturing tolerances of the busbar body.

[0009] Furthermore, movements of the busbar body relative to the module connection elements and / or further busbar units connected to the busbar body via the connection device, possibly due to vibrations, can be compensated for by corresponding movements of the coupling positions relative to the busbar body.

[0010] This allows vibrations of the busbar body to be damped by the connection device, thereby maintaining a rigid connection of the connection device to the module connection element and / or further busbar unit.

[0011] This allows for improved electrical contact between the module connection elements and / or the further busbar units via the connection device with the busbar units.

[0012] According to one embodiment, the translation direction is aligned at least partially along the longitudinal axis of the busbar body of the busbar unit and / or the rotation axis is aligned at least partially along or perpendicular to the longitudinal axis of the busbar body of the busbar unit.

[0013] This achieves the technical advantage that translational alignment at least partially along the longitudinal axis of the busbar body can account for length tolerances of the busbar body due to movements of the connection device. By orienting the rotation axis partially along the longitudinal axis or perpendicular to the longitudinal axis, tilting or torsional movements of the busbar body relative to modular connection elements or further busbar units connected to the connection unit can be compensated.

[0014] This allows for a more stable connection between the busbar unit and the module connection element or further busbar unit. Furthermore, improved electrical transmission can be achieved.

[0015] According to one embodiment, the connection unit has a through-hole designed as a slot at the connection end of the connection body, and the busbar body of the busbar unit can be connected to the module connection element and / or the further busbar unit by a screw connection via the through-hole, the connection position being determined by the positioning of the screw element in the through-hole.

[0016] This has the technical advantage that the through-holes designed as slots allow for a simple and stable connection of the busbar unit to module connection elements or further busbar units via a screw connection.

[0017] Furthermore, the slots can be used to achieve displacement of the respective screw elements that make up the threaded connection within the slots, thereby achieving length tolerances.

[0018] According to one embodiment, the longitudinal direction of the through-holes designed as slots is oriented at least partly along the translation direction.

[0019] This achieves the technical advantage that by aligning the longitudinal direction of the slot at least partially along the translational direction, displacement of the screw element within the slot can displace the coupling position defined by the positioning of the screw element in the slot along the translational direction.

[0020] According to one embodiment, the connecting body of the connection device includes a flexible portion formed between the first connecting end and the second connecting end, the flexible portion enabling elastic bending of the connection device along the bending direction.

[0021] This achieves the technical advantage that the flexible portion of the connecting body of the connection device can be used to move the first and second connecting ends of the connecting body towards each other by elastic bending of the flexible portion, thereby allowing the connecting position to be moved relative to the connecting ends of the busbar body in a translational direction or along a rotational axis.

[0022] According to one embodiment, the connection device includes a multi-layer busbar element having a bend.

[0023] This has the technical advantage of providing a robust connection device that allows for elastic movement.

[0024] According to one embodiment, the connection device comprises a braided band element and / or a fabric band element.

[0025] This has the technical advantage of providing a robust connection device in which the coupling end or coupling location can be moved in any direction relative to the connecting end of the busbar body.

[0026] By designing the connection device as a braided or fabric band, the translation or rotation axis (around which the movement of the coupling position of the connection device relative to the connection end of the busbar body is defined) can be oriented in any spatial direction, which allows for very precise compensation of tolerances.

[0027] According to one embodiment, the connection device is screwed and / or welded and / or crimped and / or stamped via the first coupling end to the connection end of the busbar body of the busbar unit.

[0028] This achieves the technical advantage that the connection device can be firmly connected to the busbar body, and furthermore, good electrical conductivity is achieved between the busbar body and the connection body of the connection device.

[0029] According to one embodiment, the connection unit at the second connection end of the connecting body of the connection device is configured for a screw connection and / or a welded connection and / or a crimped connection and / or a punched connection with the module connection element and / or the further busbar unit.

[0030] This has the technical advantage that a robust mechanical and electrical connection can be achieved between the connection device and the module connection elements and / or further busbar units, which also ensures efficient electrical transmission between the module connection elements and further busbar units and the connection device.

[0031] According to one embodiment, the connection device is spaced apart at the connection end from the center of the connection end of the busbar body.

[0032] This has the technical advantage that the connection device of the busbar body can be designed to save as much space as possible.

[0033] According to one embodiment, the connection device is designed integrally as a connection protrusion at the connection end of the busbar body of the busbar unit.

[0034] This achieves the technical advantage that a simple implementation of the connection device is possible. Furthermore, the design of the connection device as a connection protrusion integrally formed in the busbar body provides a connection device that is as robust as possible.

[0035] According to one embodiment, the busbar body of the busbar unit is made of one of the following materials: aluminum, copper, an aluminum alloy, and a copper alloy.

[0036] This has the technical advantage of being able to provide a conductive busbar unit that meets the requirements for stability and electrical transmission in each application field.

[0037] According to one embodiment, the connection body of the connection device is made of one of the following materials: aluminum, copper, an aluminum alloy, a copper alloy.

[0038] This has the technical advantage of providing a connection device with corresponding robustness, stability and conductivity that meets the requirements of the respective field of use.

[0039] According to one aspect, there is provided a module connection device for electrical connection of modules, the module connection device comprising at least one module connection element and a busbar unit according to one of the above embodiments, the module connection element including a screw element, the screw element being guided through a through-hole of a coupling unit of the connection device.

[0040] This allows the technical advantage to be achieved that the improved module connection device for connecting various electrical modules to a busbar unit according to the present invention can be provided with the above technical advantages.

[0041] According to one embodiment, the screw element of the module connection element is guided through a through-hole of the connection device of the busbar unit and is arranged so as to be movable along a translational direction and / or around a rotational axis relative to the busbar body of the busbar unit.

[0042] This achieves the technical advantage that the screw elements of the module connection elements of the module connection device, which are guided through the through-holes of the connection device, can be moved along a translational direction and / or around a rotational axis relative to the busbar body of the busbar unit, thereby enabling a corresponding movement of the busbar body of the busbar unit relative to the module connection elements of the module connection device.

[0043] This allows the module connection device to compensate for length differences, installation inaccuracies, and movement of the two components of the module connection device, i.e., the module connection element and the busbar unit, relative to each other during operation. This can be used, for example, to absorb vibrations. Thus, the electrical and mechanical connection between the module connection element and the busbar unit remains unaffected by vibrations.

[0044] According to one embodiment, a housing casing is formed on the busbar body and a casing collar is formed adjacent to the housing casing at the connection end.

[0045] This has the technical advantage that the housing casing and casing collar provide reliable insulation of the busbar bodies of the busbar unit.

[0046] According to one embodiment, the casing collar includes a flat conductive seal.

[0047] This has the technical advantage that when the casing collar is coupled to the housing unit of the modular connection device, the flat conductor seal of the casing collar provides reliable and sealed protection for the components of the modular connection device.

[0048] According to one embodiment, the modular connection element comprises a housing unit having a first housing part, a second housing part and a third housing part, wherein the first housing part defines a first receiving space with a receiving opening, the second housing part defines a second receiving space designed to communicate with the first receiving space and adjacent to the first receiving space on the side opposite the receiving opening, a busbar unit can be inserted into the housing unit through the receiving opening along a receiving direction, and upon insertion, the connection end of the busbar body can be positioned in the first receiving space and the connection device can be positioned in the second receiving space, and the third housing part is adjacent to the second housing part and comprises a through-channel for receiving a screw element, oriented perpendicular to the receiving direction of the receiving spaces.

[0049] This has the technical advantage that the housing unit provides reliable protection for the busbar unit with the connection devices and the module coupling elements with the screw elements.

[0050] According to one embodiment, the first housing part includes an aperture collar arranged around the receiving opening, the aperture collar being connectable to a casing collar of the housing casing of the busbar body.

[0051] This achieves the technical advantage that the connection between the opening collar of the first housing part of the housing unit and the casing collar of the housing casing of the busbar body enables comprehensive protection of the components of the module connection device within the housing unit.

[0052] According to one embodiment, the second housing portion comprises a flexible housing portion, and the first housing portion is movable relative to the third housing portion via the flexible housing portion.

[0053] This can achieve the technical advantage that the flexible housing part of the second housing part allows the first housing part to move relative to the third housing part, in particular allowing the busbar bodies of the busbar unit arranged in the first housing part and the module connection elements arranged in the third housing part, which are connected to each other via the connection device arranged in the second housing part, to be movable relative to each other.

[0054] This allows tolerance-compensating movements to be achieved. Thanks to the flexible housing parts, the entire housing unit 211 remains rigid despite the above-mentioned relative movements of the components with respect to one another.

[0055] According to one embodiment, the flexible housing part is made from a flexible material and / or is designed as a bellows.

[0056] This achieves the technical advantage of being able to provide a robust flexible housing portion.

[0057] According to one embodiment, an open collar is formed at each end of the through channel, allowing the screw head and sealing element of the screw element to be positioned in the protective collar, and a metal sleeve element is positioned in the through channel, allowing the screw element to pass through the sleeve element.

[0058] This achieves the technical advantage that the screw elements of the module connecting elements can be fixed and protected in the housing arrangement by the opening collars at both ends of the through-channel of the third housing part.

[0059] According to one embodiment, the screw element is designed as a three-part screw.

[0060] The technical advantage of this is that the design of the screw element as a three-part screw provides a high level of safety for the user of the modular connection device.

[0061] According to one aspect, there is provided a coupling arrangement for coupling two busbar units, the coupling arrangement comprising a coupling device, a busbar unit according to one of the above embodiments, and a further busbar unit, wherein the busbar unit and the further busbar unit are connected to each other via a connection device of the busbar units.

[0062] This allows the technical advantage to be achieved in that an improved connecting device for connecting two busbar units to a busbar unit according to the present invention can be provided with the above technical advantages.

[0063] According to one embodiment, the coupling device further comprises a protective housing unit having a first housing wall, a second housing wall and a receiving space defined between the first and second housing walls, wherein a first insertion opening is formed in the first housing wall and a second insertion opening is formed in the second housing wall, wherein a busbar unit having a connection end and a connection device can be positioned in the receiving space via the first insertion opening and a further busbar unit having a further connection end can be positioned in the receiving space via the second insertion opening, and wherein the busbar unit and the further busbar unit connected to the busbar unit via the connection device can be moved relative to each other in the receiving space.

[0064] This achieves the technical advantage that the protective housing unit of the coupling device comprehensively protects the connection of the two busbar units via the connecting device.

[0065] The two busbar units connected to each other via the connecting device can move relative to each other within the receiving space of the protective housing unit, so that tolerances can be compensated for by the mobility of the connecting device.

[0066] According to one embodiment, the protective housing unit includes a flexible housing portion disposed between a first housing wall and a second housing wall.

[0067] This has the technical advantage that the flexible housing part of the protective housing unit can compensate for the relative movement of the two busbar units.

[0068] According to one embodiment, the coupling device further comprises a screw element, and the protective housing unit comprises a housing base having a threaded region between the first housing wall and the second housing wall, and a housing cover arranged opposite the housing base, wherein a feed-through opening for passing the screw element is formed in the housing cover, and the screw element can be passed through a further through-hole formed in the further connection end of the further busbar unit and through a through-hole of the coupling device of the connecting device of the busbar unit and can be screwed into the threaded region.

[0069] This has the technical advantage that the screw elements can be used to achieve precise fastening of the two busbar units to each other and to the housing base of the protective housing unit via the connecting device, which allows for a very robust connection of the two busbar units.

[0070] According to one embodiment, the connecting device further comprises a structured annular element, the structured annular element being positionable between the busbar unit and the further busbar unit, the screw element being guideable through the structured annular element, the structured element being made of a material having a higher hardness than the connecting device and / or the further busbar unit.

[0071] This has the technical advantage that the high hardness of the structured annular element can be used to form an electrical connection between the two busbar units via the structured annular element.

[0072] The higher hardness reduces the contamination associated with oxidation on the surface of the busbar bodies of the two busbar units, thereby increasing the electrical conductivity of the connection between the two busbar units. The structured annular element is made of an electrically conductive material.

[0073] The invention will now be explained in more detail with the aid of the drawings. [Brief explanation of the drawings]

[0075] FIG. 1 is a schematic diagram of a busbar unit 100 according to an embodiment.

[0076] According to the present invention, the busbar unit 100 comprises a busbar body 101 and a connection device 103. The busbar body 101 is flat and has a rectangular shape with at least one connection end 105.

[0077] The connection device 103 has a connection body 107 having a first connection end 109 and a second connection end 111. The connection device 103 is formed at the connection end 105 of the busbar body 101 via the first connection end 109.

[0078] The connection device 103 has a connection unit 113 at the second connection end 111. The connection unit 113 defines a connection position P. According to the invention, the connection position P can be variably aligned with respect to the translation direction T and / or the rotation axis R relative to the busbar body 101 of the busbar unit 100.

[0079] In the illustrated embodiment, the connection unit 113 is designed as a through hole 115 formed as a slot.

[0080] Via the connection unit 113, the busbar unit 100 can be connected to a module connection element 201 of the module connection device 200 (neither of which is shown in Figure 1) or to a further busbar unit 303 (also not shown in Figure 1), for example via a screw connection using a screw element 117.

[0081] For this purpose, the screw element 117 can be guided through the through hole 115 and moved along the longitudinal direction L1 of the slot.

[0082] The coupling position P can be defined by the positioning of the screw element 117 in the through hole 115 of the coupling unit 113. By shifting the positioning of the screw element 117 along the longitudinal direction L1, the coupling position P can thereby be shifted relative to the busbar body 101.

[0083] In the illustrated embodiment, the longitudinal direction L1 of the through hole 115 formed as a slot is aligned at least partially along the translation direction T, thereby allowing the connection point P to be displaced relative to the busbar body 101.

[0084] In the illustrated embodiment, both the longitudinal direction L1 and the translational direction T of the slot are at least partially aligned along the longitudinal axis L of the busbar body 101.

[0085] By displacing the threaded element 117 in the slot of the connection unit 113 along the longitudinal direction L1, the connection point P can thereby be displaced along the longitudinal direction L of the busbar body 101. In particular, this makes it possible to compensate for length tolerances of the busbar body 101 when connected to a module connection element 201 of the module connection device 200 and / or when connected to a further busbar unit 303.

[0086] In the illustrated embodiment, the connection device 103 is designed as a connection lug 127. The connection lug 127 is integrally formed in the connection end 105 of the busbar body 101.

[0087] In the illustrated embodiment, the connection device 103 is also formed at the connection end 105 of the busbar body 101 at a distance from the center Z of the busbar body 101. The connection device 103 is therefore formed in a side region of the connection end 105.

[0088] In the illustrated embodiment, the busbar body 101 further includes a housing casing 205 having a casing collar 207. A flat conductor seal 209 is formed in the casing collar 207.

[0089] The housing casing 205, the casing collar 207, and the flat conductor seal 209 may be formed from an electrically insulating material, for example a plastic material.

[0090] According to one embodiment, the busbar body 101 may be made from one of the following materials: aluminum, copper, an aluminum alloy, or a copper alloy.

[0091] According to one embodiment, the connecting body 107 of the connecting device 103 may be made from one of the following materials: aluminum, copper, an aluminum alloy, or a copper alloy.

[0092] FIG. 2 is a further schematic diagram of a busbar unit 100 according to a further embodiment.

[0093] The embodiment of FIG. 2 is based on the embodiment of FIG. 1 and includes all the features described in FIG.

[0094] In the illustrated embodiment, the connection device 103 has a different design compared to the embodiment of Fig. 1. In Fig. 2, the connection device 103 is not designed as a rigid connection protrusion, but has a flexible portion 119. The connection device 103 is elastically deformable via the flexible portion 119.

[0095] In the illustrated embodiment, the connecting bodies 107 of the connecting device 103 are accordingly designed as multi-layer busbar elements 121 with bends 123. Thus, in the illustrated embodiment, the connecting device 103 can be elastically bent around the axis of rotation R by means of the bends 123. In the illustrated embodiment, the axis of rotation R is parallel to the surface 131 of the busbar body 101.

[0096] Alternatively, the axis of rotation R may be positioned in other spatial directions, and thus the connecting body 107 of the connecting device 103 can be bent around other spatial directions. For this purpose, the bending section 123 can possibly be designed with different bending directions.

[0097] The translational movement of the coupling position P takes place here as in the embodiment of FIG. 1 along the longitudinal direction L1 of the through-hole 115 of the coupling unit 113, which is designed as a slot.

[0098] Alternatively, the longitudinal direction L1 of the slot may be oriented in a different spatial direction, and therefore the translational movement along the translation direction is also oriented in a different spatial direction.

[0099] The translational and rotational movement of the connection point P relative to the busbar body 101 can compensate for corresponding tolerances in manufacturing and assembly between the busbar unit 100 and any connected module connection elements 201 of the module connection device 200 (neither of which are shown in Figure 2) or between further busbar units 303 (also not shown in Figure 2).

[0100] In the illustrated embodiment, the connection device 103 is connected to the connection end 105 of the busbar body 101 of the busbar unit 100 via a first coupling end 109 by a screw connection and / or a welded connection and / or a crimped connection and / or a stamped connection.

[0101] FIG. 3 is a further schematic diagram of a busbar unit 100 according to a further embodiment.

[0102] The embodiment of FIG. 3 is based on the embodiment of FIG. 2 and includes all the features described in FIG.

[0103] In the illustrated embodiment, the connecting body 107 of the connecting device 103 is provided with a flexible section 119 according to the embodiment of Fig. 2. To this end, in the illustrated embodiment, the connecting body 107 is designed as a braided band element 125.

[0104] The second link end 111 can be moved in any spatial direction relative to the first link end 109 and therefore relative to the busbar body 101 by the braided band element 125 .

[0105] In the illustrated embodiment, the connection device 103 is connected to a module connection element 201 of the module connection apparatus (neither of which is shown in Figure 3) or a further busbar unit 303 (also not shown in Figure 3) via a screw connection and / or a welded connection and / or a crimped connection and / or a stamped connection to a connection unit 113 formed at the second connection end 111.

[0106] 1 and 2, the connecting unit 113 in the illustrated embodiment does not have a through-hole 115 formed as a slot. The connecting position P is therefore defined by a point provided on the second connecting end 111 for the intended screw and / or welded and / or crimped and / or stamped connection.

[0107] The flexibility of the braided band element 125 allows said coupling position P to be moved relative to the busbar body 101 by rotational or torsional and / or translational movements along a translational direction T or about a rotational axis R.

[0108] 3, the translation direction T or the rotation axis R can be oriented in any spatial direction, thereby compensating for tolerances or movements of the busbar body 101 in any spatial direction.

[0109] According to the embodiment of FIGS. 1 and 2, the connection body of the connection device 103 is made of one of the following materials: aluminum, copper, aluminum alloy, copper alloy.

[0110] The connection of the first coupling end 109 to the busbar body 101 can again be effected by means of a screw connection and / or a welded connection and / or a crimped connection and / or a stamped connection.

[0111] FIG. 4 is a schematic exploded view of a module connection device 200 including a busbar unit 100 according to one embodiment.

[0112] According to the invention, a module connection device 200 for electrically connecting modules comprises at least one module connection element 201 and a busbar unit 100 according to the invention.

[0113] In the illustrated embodiment, the module connection device 200 comprises a busbar unit 100 according to the invention according to the embodiment of FIG.

[0114] According to the invention, the module connection element 201 comprises a screw element 203. The screw element 203 can be guided through a through-hole 115 of the coupling unit 113 of the connection unit 103 of the busbar unit 100.

[0115] When the screw element 203 of the module connection element 201 is positioned through the through hole 115 of the connection device 103, the screw element 203 in the illustrated embodiment can move along a translation direction T relative to the busbar body 101 of the busbar unit 100.

[0116] 1, in the illustrated embodiment, the longitudinal direction L1 of the through-hole 115 of the coupling device 113, which is designed as a slot, is at least partially aligned with the translation direction T. In other words, the translation direction T is primarily indicated by the orientation of the longitudinal direction L1 of the slot of the coupling unit 113.

[0117] When positioned through the through hole 115, the screw element 203 can thereby move along the longitudinal direction L1 of the slot and therefore along a correspondingly defined translation direction T relative to the busbar body 101.

[0118] In the illustrated embodiment, the module connecting element 201 further comprises a housing unit 211 having a first housing portion 213 , a second housing portion 215 , and a third housing portion 217 .

[0119] Here, the first housing part 213 defines a first receiving space 219 having a receiving opening 221 (neither of which are shown in detail in FIG. 4).

[0120] The second housing portion 215 therefore defines a second receiving space 223 (also not shown in FIG. 4).

[0121] In this case, the second receiving space 223 is designed to communicate with the first receiving space 219 and to be adjacent to the first receiving space on the opposite side 225 of the housing unit 211 from the receiving opening 221.

[0122] Additionally, the third housing portion 217 is formed adjacent to the second housing portion 215 such that the second housing portion 215 is formed between the first housing portion 213 and the third housing portion 217.

[0123] The third housing portion 217 includes a through channel 227 for receiving the screw element 203 .

[0124] Along the receiving direction 226 , the busbar body 101 with the connection device 103 of the busbar unit 100 can be inserted through the receiving opening 221 into the first receiving space 219 and the second receiving space 223 of the housing unit 211 .

[0125] The through channel 227 of the third housing part 217 is here formed in a direction perpendicular to the receiving direction 226 .

[0126] In the illustrated embodiment, the through channel 227 includes a first opening collar 239 at a first end 235 and a second opening collar 241 at a second end 237 located opposite the first end 235.
