[0002] DE 10 2015 216 567 A1 discloses a device for high-voltage contacting of a hybrid module. The device has a carrier plate with three busbars, which are guided through the carrier plate. In addition, DE 10 2014 017 081 A1 discloses a connection assembly for electrically contacting a battery module. In addition, WO 2016 / 062736 A1 discloses an assembly for connecting a first electrical conductor to a second electrical conductor. Summary of the invention

[0003] The object of the present invention is to provide a connection assembly and a motor vehicle having such a connection assembly, in which the contact means can be mounted in a particularly simple manner and thus can be electrically connected to one another.

[0004] This object is achieved according to the invention by a connecting assembly having the features of claim 1 and by a motor vehicle having the features of claim 15. Advantageous embodiments of the invention are the subject of the dependent claims.

[0005] A first aspect of the present invention relates to a connection assembly of a first contact device on a second contact device, in particular for a motor vehicle, also referred to as a vehicle. This means that the motor vehicle, which is preferably configured as an automobile, in particular a passenger car, has a connection assembly and therefore a contact device in its fully manufactured state. In the connection assembly, the contact device is arranged and therefore configured to transfer electrical energy, and therefore current, wherein the contact devices are in electrical contact with each other, and therefore are electrically connected to each other. Therefore, the electrical energy can be transferred from the first contact device to the second contact device and / or vice versa, for example. In particular, the electrical energy is a high voltage, or the electrical energy includes a high voltage. In other words, the contact device is preferably configured to transfer a current with a high voltage. Within the scope of the present disclosure, a high voltage and therefore the above-mentioned high voltage is understood to be a voltage greater than 50 volts, in particular greater than 60 volts and very preferably a voltage of several hundred volts.

[0006] In order to make the contact means electrically contact each other particularly simply and thus time- and cost-effectively, and thus to be able to install and thus manufacture the connection assembly particularly simply and thus time- and cost-effectively, it is provided according to the invention that the first contact means has at least or exactly two circuit elements that are constructed separately from each other and are constructed for transmitting electrical energy, namely a first circuit element and a second circuit element. Preferably, the first circuit element and the second circuit element are constructed as corresponding solid bodies. In particular, the first circuit element and the second circuit element are galvanically isolated from each other or electrically insulated from each other. The first circuit element is encapsulated by an electrically insulating first sheath. The second circuit element is encapsulated by a second sheath that is constructed separately from the first sheath. The feature that the first sheath and the second sheath are constructed separately from each other should be understood in particular that the first sheath and the second sheath are not constructed in one piece with each other, that is, they are not formed by a single piece, but that the first sheath and the second sheath are constructed separately from each other. Preferably, the first sheath and the second sheath are constructed as corresponding solid bodies.

[0007] The second contact device has at least two or exactly two circuit elements that are constructed separately from each other and are constructed for transmitting electrical energy, namely the third circuit element and the fourth circuit element. Preferably, the third circuit element and the fourth circuit element are constructed as corresponding solids. For example, the first circuit element is formed by a first metal material, and the second circuit element is formed by a second metal material. The second metal material and the first metal material can be the same. For example, the first metal material and / or the second metal material are aluminum or an aluminum alloy. Preferably, the third circuit element is formed by a third metal material and / or the fourth circuit element is formed by a fourth metal material, wherein it is conceivable that the third metal material and the fourth metal material are the same. It is conceivable that the third or fourth material is different from the first or second material, or the first metal material, the second metal material, the third metal material and the fourth metal material are the same. For example, the third or fourth metal material can be copper or a copper alloy. The third circuit element and the fourth circuit element are encapsulated by a third sheath that is common to the third circuit element and the fourth circuit element, is constructed in one piece, is electrically insulated, and is constructed separately from the first sheath and separately from the second sheath. Preferably, the corresponding sheath is constructed as a corresponding solid. Since the respective sheath electrically insulates the respective conductor element, the respective sheath is preferably designed as a respective electrical insulator and thus as a respective non-electrical conductor, the electrical conductivity of which is preferably less than 10 -8 S*cm -1. In particular, it is provided that the third circuit element and the fourth circuit element are galvanically isolated from each other or electrically insulated from each other, in particular by means of the third sheath. It is also conceivable that the first circuit element and the second circuit element are electrically insulated from each other or galvanically isolated from each other by means of the first sheath and by means of the second sheath. The feature "the third sheath is constructed in one piece" is to be understood as meaning that the third sheath is formed by a single piece, so that the third sheath is constructed as a single piece or is formed by a single piece. It is particularly conceivable that the first circuit element is particularly directly injection-coated with the first sheath, so that, for example, the first sheath is particularly directly sprayed onto the first circuit element. It is also conceivable that the second circuit element is particularly directly injection-coated with the second sheath, so that, for example, the second sheath is particularly directly sprayed onto the second circuit element. It is also possible that the third circuit element and the fourth circuit element are particularly directly injection-coated with the third sheath, so that, for example, the third sheath is particularly directly sprayed onto the third circuit element and the fourth circuit element. It is particularly conceivable that the respective sheaths are composed of the respective plastics. In particular, the corresponding encapsulation is produced by injection, in particular by plastic injection, so that, for example, the corresponding circuit element is encapsulated by the corresponding encapsulation by injection, in particular by plastic injection. In other words, it is preferably provided that the corresponding encapsulation is injected, in particular by plastic injection, in particular directly onto the corresponding circuit element. It is conceivable that the first encapsulation itself, that is to say, considered alone, is constructed in one piece and is therefore formed from a single piece. Alternatively or additionally, it can be provided that the second encapsulation itself, that is to say, considered alone, is constructed in one piece and is therefore formed from a single piece.

[0008] Furthermore, according to the invention, it is provided that the first conductor element is electrically contacted with the third conductor element and the second conductor element is electrically connected with the fourth conductor element via corresponding recesses of the respective encapsulation, which are in particular designed as through-holes.

[0009] The corresponding line element is configured as a busbar, in particular as a high-voltage busbar. It is particularly conceivable that the corresponding line element has two mutually opposed wide sides and two mutually opposed narrow sides arranged between the wide sides. In addition, it is conceivable that the corresponding line element has a rectangular cross-section. On the one hand, it is possible through the present invention to operate or manipulate the third line element and the fourth line element at the same time, in particular by making the third line element and the fourth line element be encapsulated by a common third sheath and thus be wrapped, and thus the third line element and the fourth line element are particularly simple and thus time- and cost-effectively installed. On the other hand, the first line element and the second line element can be advantageously moved relative to each other and relative to the third line element and the fourth line element by making the first line element and the second line element be individually encapsulated by the first sheath and the second sheath and thus be wrapped, so that tolerances can be particularly advantageously compensated. Thus, the connection assembly can be particularly time-saving and cost-effectively manufactured as a whole, and thus installed. Here, the present invention is particularly based on the following recognition and consideration: in a vehicle, such as an electric vehicle, in particular a battery-electric vehicle, for the wiring of each component, a flexible round conductor in a high-voltage vehicle power system is mainly used. However, as the power increases, it is advantageous to use at least substantially rigid lines, such as busbars or current tubes, in order to achieve cost and space advantages in development. However, these rigid line elements, which are also simply referred to as lines, have the technical disadvantage that their flexibility is limited, especially with regard to bending. This means that the smaller the distance of the line fixture, for example on the vehicle body or on the surrounding components, relative to the contact interface, the greater the force expenditure for moving the corresponding line element, especially relative to the corresponding contact interface. In addition, the position of the bend must usually be taken into account in flat conductors, because the bending forces are much smaller on the long sides, therefore on the wide sides, than on the short sides, therefore on the corresponding narrow sides.

[0010] As a contact technology, such a contact technology can be used, which is provided with direct contact or includes direct contact by means of, for example, metric screws, so as to, for example, generate the contact normal force required for reliable current carrying capacity. On the contact surface of the circuit element or the contact sleeve, for example, electroplated precious metal coatings, such as tin, silver and / or the like, can be used as required to ensure good contact resistance. In a circuit made of an aluminum alloy, in order to make multiple detachable contacts in the contact area, at least one contact sleeve made of a copper alloy and an electroplated precious metal coating are provided on the contact area according to the current prior art. The contact sleeve can have a material lock connection with a busbar formed of, for example, aluminum and therefore constructed as an aluminum rail. According to the implementation scheme and requirements of the corresponding contact position, a flat or conical or structured surface can be provided between the contact positions, which surface can generate a favorable and required minimum contact normal force by an external screw.

[0011] In vehicle integration, line groups can be additionally separated for reasons of installability, so that the corresponding vehicle can be assembled without additional installation costs or additional modifications to the components. Depending on the embodiment of the number of conductors, a line group having a plug at each of the respective ends with such functional separability is referred to as an x-pole separation location. Therefore, with respect to the connection assembly according to the invention, it is provided, for example, that the first line element is electrically contacted with the third line element at a first contact location, also referred to as the first separation location. Thus, for example, the second line element is electrically contacted with the fourth line element as a second contact location, also referred to as the second separation location. For example, the line elements in the connection assembly according to the invention are constructed as at least essentially rigid busbars, wherein the present invention achieves particularly advantageous installability and can be implemented in a time- and cost-effective manner. In conventional solutions, there are usually at least the following disadvantages:

[0012] A limited number of installation options;

[0013] In the case of multi-pole contacting, tolerance compensation between the two separation point halves can only be achieved to a very limited extent, i.e. due to position tolerances and production tolerances, assembly is not possible or can only be achieved with increased force expenditure, since the bending forces, especially in cubic structures, increase with the height of the busbar;

[0014] Possible risk of damage to interfaces and environmental components;

[0015] The use of single-pole contact systems for the disconnection points of multi-pole conductor groups increases the complexity in additional safety sensors such as temperature sensors, HV interlocks, since these sensors must be used for each contact.

[0016] The above-mentioned disadvantages can be avoided by the present invention. Here, for example, the first circuit element and the first sheath, also referred to as the first housing, form a particularly precisely monopolar first part, and thus, for example, the second circuit element and the second sheath, also referred to as the second housing, form a particularly precisely monopolar second part. The third circuit element and the fourth circuit element and the third sheath, also referred to as the third housing, form a particularly precisely bipolar third part, which, in particular due to the one-piece design of the third sheath, can be handled as a whole, that is to say as a complete unit. This allows for a flexible and therefore time- and cost-effective installation.

[0017] In a particularly advantageous embodiment of the invention, the first covering and the second covering are mechanically connected to the third covering via corresponding through-holes which are designed as elongated holes. The elongated holes allow tolerance compensation, thus, for example, tolerances caused by production and / or by assembly, in particular by virtue of the fact that the first covering and the second covering can each be positioned in a plurality of mutually different positions relative to the third covering and can be fastened to the third covering in the corresponding positions.

[0018] In order to be able to compensate tolerances particularly simply and advantageously and thus time- and cost-effectively, in a further embodiment of the invention it is provided that the slot is formed in the third sheath. This is to be understood in particular as follows: Since the third sheath is formed in one piece and is thus formed from a single part, the third sheath is or forms a body formed in one piece and is thus formed from a single part, which is in particular the aforementioned monolithic block. The through-holes thus pass through sub-regions of the body. It is provided in particular that the through-holes are separated from one another. This is to be understood in particular as to be arranged between the through-holes, in particular solid wall regions of the through-holes.

[0019] In order to be able to manufacture the connection assembly particularly simply and thus in a time- and cost-effective manner, and thus to be able to mount it, and in this case to be able to compensate tolerances particularly advantageously, it is provided in a further embodiment of the invention that the respective through-holes are penetrated by respective threaded elements, by means of which the first and second sheaths are screwed to the third sheath and are thus mechanically connected to the third sheath. This is to be understood in particular to mean that, for example, the first through-hole of the through-holes is particularly exactly penetrated by the first threaded element of the threaded elements, and the second through-hole of the through-holes is particularly exactly penetrated by the second threaded element of the threaded elements. By means of the first threaded element, for example, the first sheath is screwed to the third sheath and is thus screwed to the third sheath, whereby the first sheath is mechanically connected to the third sheath. By means of the second threaded element, for example, the second sheath is screwed to the third sheath and is thus screwed to the third sheath, whereby the second sheath is mechanically connected to the third sheath.

[0020] In another particularly advantageous embodiment of the invention, the first and second sheaths are latched with the third sheath by means of corresponding latching elements. This should be understood in particular that the first sheath is latched with the third sheath by means of a first latching element of the latching element, and the second sheath is latched with the third sheath by means of a second latching element of the latching element, whereby the first sheath and the second sheath are mechanically connected to the third sheath. In particular, in combination with the above-mentioned threaded connection of the first and second sheaths with the third sheath, the corresponding latching can be a pre-latching, so that the connecting assembly can be produced, for example, in this way: first, for example, the first sheath is latched with the third sheath. In addition, for example, the second sheath is first latched with the third sheath. As a result, the first and second sheaths are mechanically connected to the third sheath. In order to simply and securely fasten the first and second sheaths to the third sheath, the first and second sheaths are then, that is, after latching, screwed to the third sheath. As a result, a particularly simple and therefore time- and cost-effective installation can be achieved.

[0021] In another particularly advantageous embodiment of the present invention, a first contact sleeve is assigned to the first circuit element, which is separate from the first circuit element, in particular separate from each of the circuit elements, and in particular directly in electrical contact with the first circuit element. A second contact sleeve is assigned to the second circuit element, which is separate from the second circuit element, in particular separate from each of the circuit elements, and in electrical contact with the second circuit element. A third contact sleeve is assigned to the third circuit element, which is separate from the third circuit element, in particular separate from each of the circuit elements, and in electrical contact with the third circuit element. A fourth contact sleeve is assigned to the fourth circuit element, which is separate from the fourth circuit element, in particular separate from each of the circuit elements, and in electrical contact with the fourth circuit element. Since a corresponding contact sleeve is assigned to a corresponding circuit element, the corresponding contact sleeve is conversely assigned to a corresponding circuit element. It is particularly conceivable that the corresponding contact sleeve is in direct contact with the corresponding assigned circuit element. In particular, it is provided that the contact sleeves are configured separately from one another. It is conceivable that the individual contact sleeves and the corresponding associated circuit elements consist of different, in particular metallic materials. It is therefore conceivable that the respective contact sleeves consist of copper or a copper alloy. Here, for example, the respective circuit elements consist of aluminum or an aluminum alloy. It is therefore particularly conceivable that the circuit elements consist of the same, in particular metallic material, for example aluminum or an aluminum alloy. It is also conceivable that the individual contact sleeves consist of the same, in particular metallic material, for example copper or a copper alloy.

[0022] The first contact sleeve is in direct electrical contact with the third contact sleeve and the second contact sleeve is in direct electrical contact with the fourth contact sleeve via the recesses, whereby the connecting arrangement can be produced and assembled particularly simply and therefore particularly cost-effectively and in a time- and cost-effective manner.

[0023] It has proven to be particularly advantageous that the third contact sleeve and the fourth contact sleeve are each assigned an electrically insulating contact protection element, which protrudes in the axial direction of the respective contact sleeve beyond the respective contact sleeve to which the respective contact protection element is assigned. For example, the respective contact protection element is constructed separately from the third sheath and is at least indirectly, in particular directly, held on the third sheath. Since the respective contact protection element is constructed in an electrically insulating manner, the respective contact protection element is preferably an insulator and thus a non-conductor, whose electrical conductivity is less than 10-8 S*cm. -1 As a result, a particularly high level of safety can be achieved in a particularly simple manner, so that the connecting assembly can be produced or installed, for example, by personnel in a particularly simple and therefore time- and cost-effective manner.

[0024] In order to be able to connect the contact means, in particular the circuit elements, to one another, in particular electrically and mechanically, particularly simply and therefore particularly time- and cost-effectively and particularly reliably and firmly, it is provided in a further embodiment of the invention that the third contact sleeve is assigned a first threaded sleeve, which is separate from the third contact sleeve, in particular is constructed separately from the contact sleeves, and is particularly directly connected to the third contact sleeve, for example welded or soldered. The fourth contact sleeve is assigned a second threaded sleeve, which is separate from the fourth contact sleeve, in particular is constructed separately from the contact sleeves, and is particularly directly connected to the fourth contact sleeve, in particular welded or soldered. In this case, a first screw is provided which passes through the first contact sleeve and is screwed into the third contact sleeve and into the first threaded sleeve, the first screw being provided in addition to the previously mentioned threaded element. In particular, the first screw is screwed directly into the first threaded sleeve. For this purpose, for example, the first screw has a first external thread and the first threaded sleeve has a first internal thread, wherein the first external thread can be screwed directly into the first internal thread. By means of the first screw, the first contact sleeve is screwed, in particular directly against the third contact sleeve, whereby the first contact sleeve and the third contact sleeve and also the first circuit element and the third circuit element are in electrical contact with each other. Furthermore, for example, the first circuit element and the third circuit element and the first contact sleeve and the third contact sleeve are mechanically connected to each other.

[0025] A second screw is also provided, in particular in addition to the threaded element and in addition to the first screw, which passes through the second contact sleeve and engages in the fourth contact sleeve and the second threaded sleeve and is in particular screwed directly into the second threaded sleeve. For this purpose, for example, the second screw has a second external thread and the second threaded sleeve has a second internal thread, for example, the second external thread is screwed directly into the second internal thread. By means of the second screw, the second contact sleeve is screwed, in particular directly against the fourth contact sleeve, whereby the second contact sleeve and the fourth contact sleeve and also the second circuit element and the fourth circuit element are electrically contacted with each other and in particular mechanically connected to each other.

[0026] It has proven to be particularly advantageous for the connection assembly to have a cover which is designed separately from the sheath and separately from the screw and is preferably electrically insulating, thus being designed as a non-electrical conductor, which is mechanically connected to the first sheath and / or to the second sheath and completely covers the screw in the axial direction of the respective screw. As a result, for example, in the fully assembled state of the connection assembly, the cover can avoid undesired direct contact between a person and the screw, so that a particularly high level of safety can be achieved. The connection assembly can be manufactured particularly time- and cost-effectively. For example, the cover is formed from a particularly electrically insulating plastic, such as the aforementioned plastic.

[0027] It has proven to be particularly advantageous here if the cover is sealed relative to the first encapsulation and relative to the second encapsulation by means of corresponding sealing elements. This allows a particularly high level of safety to be achieved, and the connecting assembly can be manufactured and thus assembled particularly time- and cost-effectively.

[0028] In a further particularly advantageous embodiment of the invention, at least one or exactly one temperature sensor designed to detect a temperature is embedded in the third sheath. The temperature sensor is connected to the connecting element, in particular in such a way that an electrical signal provided or available by the temperature sensor and representing the temperature detected by means of the temperature sensor can be transmitted by the temperature sensor to or on the connecting element, also referred to as a connecting element. The connecting element is also referred to as a first connecting element or a first connecting element. The electrical signal provided or available by the temperature sensor and representing the temperature detected by means of the temperature sensor can be provided via the first connecting element. In particular, the first connecting element is a first plug element, also referred to as a first plug.

[0029] The temperature sensor is, for example, or forms a sensor device or is a component of a sensor device, by means of which the connection assembly can be advantageously monitored. By embedding the temperature sensor in the third sheath, the temperature sensor is arranged in the third sheath and is therefore arranged at the third sheath, so that the process can be reliably detected and the process can be reliably monitored. The temperature sensor can be connected to a so-called interlock (HV-high voltage), for example, which is constructed as an HV interlock, either unipolarly or multipolarly, in particular in series, so that, for example, only bipolar, that is to say, precisely bipolar signal lines are necessary or provided for evaluation. For example, the signal can be transmitted to a signal line, which is also simply referred to as a line. In particular, the signal can be transmitted to the evaluation electronics and, in particular, received by the evaluation electronics via the line and, therefore, via the first connecting element. Depending on the temperature, the resistance, in particular the magnitude of its resistance value, can be determined and thus identified. In particular, the evaluation electronics can unambiguously detect, by determining the temperature and thus the magnitude of the resistance value, whether the interlock is open (infinite magnitude of the resistance value) or closed (reasonable dependence of the resistance value on the temperature) and whether the temperature sensor is operating within a plausible range, for example. In other words, the connection assembly can be monitored by means of the evaluation electronics depending on the temperature.

[0030] It has been found to be particularly advantageous that the cover has a second connection element corresponding to the first connection element and constructed separately from the first connection element, which second connection element is designed, for example, as a second plug element, that is, as a second plug. In this case, the first connection element and the second connection element are inserted into each other in a particularly non-destructive and removable manner and thereby electrically contact each other and preferably also mechanically connected to each other, whereby the signal can be transmitted from the first connection element to the second connection element. Thus, a particularly high level of safety can be achieved in a particularly simple manner, in particular in that or in that the cover, which is also referred to as a maintenance cover, is structurally designed such that the cover is firstly fixable or fixable to the first sheath and / or to the second sheath, and that only when the cover is connected to the first sheath and / or the second sheath and here or thereby the second connection element is in electrical contact with the first connection element, can the contact of the first connection element, also referred to as a signal contact, be achieved, for example, via the previously mentioned line.

[0031] Here, it has been shown to be particularly advantageous to provide a third connection element which is constructed separately from the first connection element and separately from the second connection element, which third connection element can also be referred to as or constructed as a third plug or a third plug element. Here, the second connection element and the third connection element can be inserted into each other in a particularly non-destructive and removable manner and thus electrically contact each other and preferably mechanically connected to each other, whereby the signal can be transmitted from the second connection element to the third connection element. For example, the third connection element is a component of the above-mentioned circuit. For example, the third connection element may not be directly in electrical contact with the first connection element, but the third connection element may be in electrical contact with the first connection element only under the mediation of the second connection element, so that, for example, the third connection element can only be indirectly in electrical contact with the first connection element when the second connection element is installed and is in electrical contact with the first connection element here. Here, the third connection element can be in electrical contact with the first connection element only under the mediation of the second connection element, so that the circuit can be installed when the cover is installed. In this way, a particularly high safety can be ensured in a particularly simple way.

[0032] Finally, it has proven to be particularly advantageous if the first encapsulation and the second encapsulation are sealed relative to the third encapsulation by means of corresponding sealing elements, whereby a particularly high level of safety can be achieved in a particularly simple and cost-effective manner.

[0033] A second aspect of the invention relates to a motor vehicle, also simply referred to as a vehicle, which is preferably designed as a car, in particular a passenger car. The motor vehicle according to the second aspect of the invention has at least one connection assembly according to the first aspect of the invention. The advantages and advantageous configurations of the first aspect of the invention can be regarded as advantages and advantageous configurations of the second aspect of the invention, and vice versa.

[0047] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0048] Figure 1 The schematic diagram shows two components 1 and 2 of a motor vehicle, also referred to as a vehicle, which is preferably designed as a motor vehicle, in particular as a passenger car, and which has the components 1 and 2 in its fully manufactured state. The components 1 and 2 are connected by Figure 1 The connection components 3 shown schematically in particular in the figure are electrically connected to each other, so that, for example, electrical energy can be transmitted from one of the components 1 and 2 to the other component 2, 1 and / or vice versa through the connection component 3. The transmission of electrical energy can be understood in particular as transmitting a current with a voltage. It is completely preferred that the voltage is a high voltage, also referred to as a high voltage voltage, so that the voltage is preferably greater than 50 volts, in particular greater than 60 volts, and most preferably several hundred volts. Therefore, the transmission component 3 is particularly configured to transmit a current with a voltage that is greater than 50 volts, in particular greater than 60 volts and very preferably several hundred volts. For example, one of the components 1 and 2 is configured as an electric motor, by which the vehicle can be driven in a purely electrical manner. The other component 2, 1 is configured, for example, as an electric energy storage device, which can be configured in particular as a battery, in particular as a high-voltage battery. The motor and the electric energy storage device are preferably high-voltage components, and their corresponding voltages, in particular the electrical operating voltage and the rated voltage are preferably greater than 50 volts, in particular greater than 60 volts and very preferably several hundred volts.

[0049] from Figure 2It can be seen particularly clearly that in the connecting component 3, the first contact device 4 is arranged on the second contact device 5 in such a way that the contact devices 4 and 5, which are provided for transmitting electrical energy and are thus constructed, are in electrical contact with each other. Here, the first contact device 4 has two circuit elements which are constructed separately from each other and are constructed for transmitting electrical energy, namely a first circuit element 6 and a second circuit element 7. In the embodiment shown in the figure, the circuit elements 6 and 7 are constructed as busbars. The individual circuit elements 6, 7 are constructed as a solid. The individual circuit elements 6, 7 are formed from a metal material, in the present case from aluminum, in particular from an aluminum alloy. In particular, the circuit elements 6 and 7 are galvanically isolated from each other or electrically insulated from each other. In combination Figure 3 It can be seen particularly well that first circuit element 6 is enclosed, in particular directly, by first electrically insulating sheath 8. Furthermore, second circuit element 7 is enclosed, in particular directly, by second electrically insulating sheath 9 which is designed separately from first sheath 8. Sheaths 8 and 9 are also referred to as outer coverings. It can be seen that circuit elements 6 and 7 are surrounded individually by respective sheaths 8 , 9 , in particular so that sheath 8 is injected, in particular directly, onto circuit element 6 and sheath 9 is injected, in particular directly onto circuit element 7 .

[0050] The second contact device 5 has two circuit elements which are constructed separately from each other and are designed to transfer electrical energy, namely a third circuit element 10 and a fourth circuit element 11. In the present case, the circuit elements 10 and 11 are designed as busbars. The circuit elements 10 and 11 are designed as solid bodies. The circuit elements 10 and 11 are, for example, galvanically isolated from each other, in particular electrically insulated from each other. For example, the individual circuit elements 10, 11 are formed from a metal material, in particular from aluminum and very particularly from an aluminum alloy. Preferably, the circuit elements 6, 7, 10 and 11 are formed from the same metal material, in particular from the same aluminum alloy. In combination Figure 3 It can be seen particularly well that the circuit elements 10 and 11 are in particular directly encapsulated by a third, electrically insulating, encapsulation 12 which is common to the circuit elements 10 and 11 and is formed in one piece, and which is also referred to as a third housing. The third encapsulation 12 is formed separately from the encapsulation 8 and separately from the encapsulation 9. In particular, the respective encapsulation 8, 9, 12 is formed as a respective solid. More particularly, the respective encapsulation 8, 9, 12 is formed from plastic. For example, the encapsulation 12 is in particular injected directly onto the circuit elements 10 and 11.

[0051] from Figure 2It can be seen that the first conductor element 6 is in electrical contact with the third conductor element 10, and the second conductor element 7 is in electrical contact with the fourth conductor element 11 via corresponding recesses 13, 14, 15 and 16 of the sheaths 8, 9 and 12, which are designed as through holes here. Here, recess 13 is the first recess of the sheath 8, recess 15 is the second recess of the sheath 9, recess 14 is the third recess of the sheath 12, and recess 16 is the fourth recess of the sheath 12.

[0052] from Figure 5 As can be seen in the figure, a first long hole 17 configured as a through hole is configured in the first sheath 8. A second long hole 18 configured as a through hole is configured in the sheath 9. The long hole 17 is arranged overlapping with the corresponding first threaded opening 19, and the long hole 18 is arranged overlapping with the corresponding second threaded opening 20. The threaded openings 19 and 20 are arranged, i.e. configured, in the third sheath 12, wherein, for example, the corresponding threaded openings 19, 20 can be configured as through holes. Fig.10 As can be seen, the long hole 17 and the threaded opening 19 are assigned a first threaded element 21 configured as a screw, which passes through the long hole 17 and is screwed into the threaded opening 19. The long hole 18 and the associated threaded opening 20 are assigned a second threaded element 22 configured as a second screw, which passes through the long hole 18 and is screwed into the threaded opening 20. Therefore, the first sheath 8 is screwed to the third sheath 12 by means of the threaded element 21 and is thus mechanically connected to the third sheath 12. The sheath 9 is connected to the sheath 12 by means of the threaded element 22 and is thus mechanically connected to the sheath 12. It can be seen that the sheaths 8 and 9 are screwed against the sheath 12 by means of the threaded elements 21 and 22 and are thus mechanically connected to the sheath 12. It is conceivable here that a corresponding thread, in particular designed as an internal thread, is arranged in the corresponding threaded opening 19, 20 in such a way that the corresponding thread arranged in the corresponding threaded opening 19, 20 is formed by an in particular metallic threaded insert which is embedded, for example, in the sheath 12. The slots 17 and 18 here enable a particularly advantageous, in particular translational and / or rotational tolerance compensation between the corresponding sheath 8, 9 and the sheath 12.

[0053] Furthermore, a latching connection between the individual sheaths 8, 9 and the sheath 12, which is in particular designed as a pre-locking connection, is provided in the connection assembly 3. Figure 6 , 7As can be seen in FIGS. 8 and 9 , for this purpose, the respective coverings 8 , 9 have at least one corresponding latching element 23 , 24 which latches with a corresponding corresponding latching element 25 , 26 of the third covering 12 . This allows for a reliable operation during the assembly process, in which the connecting assembly 3 is manufactured and assembled, for example for the person who manufactures and assembles the connecting assembly 3 . For example, the corresponding latching elements 23 , 24 and / or the corresponding and / or the corresponding latching elements 25 , 26 have corresponding introduction bevels 27 , 28 , by which the latching elements 23 and 25 or 24 and 26 can be latched to each other particularly easily and advantageously.

[0054] from Figure 2 As can be seen in FIG. 1 , a first contact sleeve 27 is assigned to the first conductor element 6, which is designed separately from each of the conductor elements 6, 7, 10 and 11 and is in particular directly electrically connected to the first conductor element 6. A second contact sleeve 28 is assigned to the second conductor element 7, which is designed separately from each of the conductor elements 6, 7, 10 and 11 and is in particular directly electrically contacted with the conductor element 7. A third contact sleeve 29 is assigned to the third conductor element 10, which is designed separately from each of the conductor elements 6, 7, 10 and 11 and is in particular directly electrically contacted with the conductor element 10. A fourth contact sleeve 30 is assigned to the fourth conductor element 11, which is designed separately from each of the conductor elements 6, 7, 10 and 11 and is in particular directly electrically contacted with the conductor element 11. Contact sleeves 27, 28, 29 and 30 are designed separately from one another. In particular, the contact sleeves 27, 28, 29 and 30 consist of the same, in particular metallic material, in particular copper or a copper alloy. The contact sleeves 27 and 29 are in direct electrical contact with one another, in particular in such a way that the respective end faces of the contact sleeves 27 and 29 directly support one another in the axial direction of the respective contact sleeves 27, 29. The contact sleeves 28 and 30 are in electrical contact with one another, in such a way that the respective end faces of the contact sleeves 28 and 30 directly support one another in the axial direction of the respective contact sleeves 28, 30. Thus, the circuit elements 6 and 10 are in electrical contact with one another via the contact sleeves 27 and 29, and the circuit elements 7 and 11 are in electrical contact with one another via the contact sleeves 28 and 30.

[0055] from Figure 7 It can be seen particularly well that the contact sleeve 29 is assigned a first contact protection element 31 and the contact sleeve 30 is assigned a second contact protection element 32. The respective contact protection element 31, 32 protrudes beyond the respective assigned contact sleeve 29, 30 in the axial direction of the respective contact sleeve 29, 30, thereby providing particularly advantageous contact protection. In particular, the respective contact protection element 31, 32 is electrically insulating and is here in particular made of electrically insulating plastic. Figure 2 It can be seen that the contact protection element 31 engages in the contact sleeve 27 and the contact protection element 32 engages in the contact sleeve 28 .

[0056] A first threaded sleeve 33 is assigned to the third contact sleeve 29 and engages in the contact sleeve 29. A second threaded sleeve 34 is assigned to the fourth contact sleeve 30 and engages in the contact sleeve 30. The threaded sleeves 33 and 34 are designed separately from each other and separately from the contact sleeves 27, 28, 29 and 30. In this case, the threaded sleeve 33 is in particular directly connected to the contact sleeve 29 and the threaded sleeve 34 is in particular directly connected to the contact sleeve 30. A first screw 35 is provided, which passes through the first contact sleeve 27 and engages in the contact sleeve 29 and the threaded sleeve 33 and is in particular screwed directly into the threaded sleeve 33, by means of which the first contact sleeve 27 is in particular screwed directly against the third contact sleeve 29, whereby the first contact sleeve 27 and the third contact sleeve 29 and also the first circuit element 6 and the third circuit element 10 are in electrical contact with each other. A second screw 36 is also provided, which penetrates the second contact sleeve 28 and engages in the threaded sleeve 34 and the contact sleeve 30 and is in particular screwed directly into the threaded sleeve 34, by means of which the second contact sleeve 28 is screwed, in particular directly, against the fourth contact sleeve 30. As a result, the second contact sleeve 28 and the fourth contact sleeve 30 and also the second circuit element 7 and the fourth circuit element 11 are in electrical contact with one another. The respective screw 35, 36 is supported by its respective screw head and here by the respective washers 37, 38, which are optionally provided in the present case, on the respective contact sleeve 27, 28 and / or on the respective circuit element 6, 7, in particular in the axial direction of the respective screw 35, 36. On the respective first side S1 of the sheath 12 facing away from the circuit elements 6 and 7 and away from the sheaths 8 and 9, the screws 35 and 36 and the contact sleeves 29 and 30 and the threaded sleeves 33 and 34 and also the circuit elements 10 and 11 are completely covered by the sheath 12 and are therefore covered and in particular electrically insulated. On the respective second side S2 of the respective covering 8 , 9 facing away from or away from the covering 12 , the following is arranged: On the respective second side S2 of the respective covering 8 , 9 , a cover 39 , also referred to as a maintenance cover, is arranged, which cover can be opened in particular from Figure 3 and 4. The cover 39 is designed separately from the sheaths 8, 9 and 12 and separately from the screws 35 and 36 and also separately from the threaded elements 21 and 22, wherein provision is made here for the screws 36 and 35 to be provided in addition to the threaded elements 21 and 22. The screws 35 and 36 are completely covered on the respective second side S2 by means of the cover 39 and are therefore covered and electrically insulated, wherein the cover 39 also covers, for example, the washers 37 and 38 and / or the line elements 6 and 7 on the respective side S2, in particular completely. The cover 39 is in particular an electrically insulating cover and is formed here from an electrically insulating material, in particular plastic.

[0057] from Fig. 9 4, the cover 39 has receptacles 40 and 41, wherein the screw 35, in particular its screw head, is at least partially received in the receptacle 40 and the screw 36, in particular its screw head, is at least partially received in the receptacle 41. The respective receptacle 40, 41 is surrounded in its circumferential direction, in particular completely around, by the respective sealing element 42, 43, wherein the cover 39 is sealed with respect to the respective sheath 8, 9 by means of the sealing elements 42 and 43, in particular, the cover 39 is sealed with respect to the sheath 8 by means of the sealing element 42 and with respect to the sheath 9 by means of the sealing element 43.

[0058] from Figure 2 and Fig.11 As can be seen in FIG. 1 , at least one or exactly one temperature sensor 44 is embedded in the third sheath 12, by means of which the temperature can be detected. The temperature sensor 44 can provide an electrical signal, which characterizes, that is to say describes, the temperature detected by means of the temperature sensor 44. The temperature sensor 44 is in electrical contact, that is to say connected, with a first connection element 45, wherein the connection element 45 is held on the third sheath 12, in particular is at least partially embedded in the sheath 12. The first connection element 45 can provide a signal, so that the signal can be provided by the temperature sensor 44 via the connection element 45. This signal can be received, for example, by evaluation electronics, so that the evaluation electronics can monitor the connection assembly 3 based on the signal.

[0059] from Fig.12 As can be seen in FIG. 3 , the cover 39 has a second connection element 46 corresponding to the first connection element 45 and constructed separately from the connection element 45, wherein the first connection element 45 and the second connection element 46 can be inserted into each other in a non-destructive and removable manner and thus are in electrical contact with each other. As a result, a signal can be transmitted from the connection element 45 to the connection element 46 and provided by the connection element 46. It is also provided in Fig.124 , which is configured separately from the connection element 45 and separately from the connection element 46. The connection element 47 is also a component of a line 48, referred to as a signal line, via which signals can be transmitted, in particular from the connection element 46 to the evaluation electronics. The evaluation electronics can thus receive signals via the line 48. In the state in which the connection assembly 3 is completely assembled, the second connection element 46 and the third connection element 47 are inserted into one another and thus electrically contact one another, whereby the signal can be transmitted from the second connection element 46 to the third connection element 47. Here, for example, the connection elements 45 and 46 are inserted into one another in such a way that the connection element 46 is inserted into the connection element 45. The connection elements 46 and 47 are inserted into one another, for example, in such a way that the connection element 47 is inserted into the connection element 46 or vice versa. The connection elements 45, 46 and 47 are thus plugs. With respect to the connection elements 45, 46 and 47, the connection element 47 cannot be electrically contacted with the connection element 45 without the connection element 46, so that the connection element 47 can only be electrically contacted with the connection element 45 through the mediation of the connection element 46. This ensures a particularly secure mounting of the connection assembly 3. Preferably, the corresponding screws 35, 36 are M6 screws and / or are contact-protected. In particular, the connection element 47 is a communication plug, via which signals can be transmitted to the evaluation electronics. The cover 39 is held on the sheath 8 by means of screws. For this purpose, as shown in FIG. Figure 5 As can be seen in FIG. 8 , the sheath 8 has a threaded opening 49, which is designed as a through hole, for example. A second thread, which is designed as an internal thread, is arranged in the threaded opening 49, for example, wherein the second thread is formed, for example, by a threaded insert, which is embedded, for example, in the sheath 8. The threaded opening 49 is assigned a threaded element 50 ( Fig.10 ). The threaded element 50 passes through the corresponding Fig. 9 The cover 39 is screwed into the corresponding threaded opening 49 and is thereby screwed to the encapsulation 8. The cover 39 is thereby screwed to the encapsulation 8 and is thereby held on the encapsulation 8 and also on the encapsulation 9.

[0060] from Figure 6 It can be seen particularly clearly in FIG. 1 that the elongated holes 17 and 18 of the coverings 8 and 9 are designed as through holes.

[0061] from Figure 7 , it can be seen that the encapsulation 12 is sealed relative to the encapsulation 8 by means of a sealing element 52 and relative to the encapsulation 9 by means of a sealing element 53. In the present case, the sealing element 52 extends completely around the contact sleeve 29 in the circumferential direction of the contact sleeve 29, and the sealing element 53 extends completely around the contact sleeve 30 in the circumferential direction of the contact sleeve 30.

[0062] from Figure 7The arrangement of the cover 39 on the sleeves 8 and 9 can be seen particularly well in FIG. Figure 5 As can be seen in the figure, the slots 17 and 18 allow a rotational tolerance compensation of up to + / -3 degrees in the present case between the respective sheaths 8, 9 and the sheath 12. In addition, a particularly advantageous radial and axial sealing can be achieved by means of the sealing elements 52 and 53. In addition, defined drainage holes can be achieved, thereby preventing water from penetrating into the sealing elements 52, 53. In particular, the drainage holes are arranged between the locking parts of the respective locking elements 23, 24, especially when viewed in the circumferential direction of the respective screws 35, 36. In particular, it is conceivable that the respective sealing elements 52, 53, in particular when viewed in their respective cross-sections, are constructed in an L-shape and / or have at least two or exactly two tabs, so as to thereby achieve a particularly advantageous, in particular radial and axial sealing effect. The corresponding situation can be transferred to the respective sealing elements 42, 43 at or in the cover 39. For example, the respective sealing element 42, 43 is designed to be L-shaped, especially when viewed in its respective cross section, and / or the respective sealing element 42, 43 has at least two or exactly two webs, in particular in order to achieve a particularly advantageous radial and axial sealing effect. In particular, the latching portion forms a segmented gripping collar, which is segmented in the circumferential direction of the respective screw 35, 36, so that in the circumferential direction of the respective screw 35, 36, the respective drainage opening is arranged, in particular as a respective through-opening, between the respective latching portions.

[0063] In particular, it is possible that the circuit elements 6 and 7 are connected to the circuit elements 10 and 11 independently of one another and in particular successively. First, for example, the respective sheaths 8, 9 are latched and thus pre-latched with the sheath 12. Then, the respective sheaths 8, 9 are screwed with the sheath 12, in particular by means of a pre-screw connection and in this case in particular by means of the screw elements 21 and 22. Then, for example, an electrical screw connection is made in such a way that the screws 35 and 36 are screwed and in particular screwed on or tightened. As a result, the circuit element 6 is in electrical contact with the circuit element 10 and the circuit element 7 is in electrical contact with the circuit element 11, and the circuit elements 6 and 7 are also mechanically and fixedly connected to the circuit elements 10 and 11. Then, the cover 39 is mounted, which, as described above, is screwed with the sheath 12 in particular by means of the screw element 50. In this way, in particular, a decoupling of the mechanical connection and the electrical connection can be achieved by means of an additional mechanical screw connection, that is, a mechanical pre-screw connection provided in addition to the electrical screw connection, which is designed as a mechanical pre-screw connection and can be achieved by means of the screw elements 21 and 22. Here, the respective screws can be mounted in a way that they cannot be lost.

[0064] The temperature sensor 44 is, for example, a PTC element, which is encapsulated by the sheath 12, in particular injection encapsulated. The line 48 is in particular a line of the onboard power supply, so that the first connecting element 45 can be electrically connected to the onboard power supply via the connecting elements 46 and 47. In particular, the connecting element 46 comprises a pin housing, in particular with an integrated stamped grid on both sides. For example, the connecting element 47, which is configured as an onboard power supply plug, cannot be directly inserted into or onto the connecting element 45, but must be electrically contacted with the connecting element 45 under the mediation of the connecting element 46. This can ensure that incorrect connections are prevented. In particular, the following advantages can be achieved:

[0065] simplified installation in the frame and access;

[0066] New wiring options are possible in development;

[0067] Cost savings due to minimal signal evaluation in the multi-pole separation area and its evaluation electronics;

[0068] By reducing the smaller static failure rate caused by the contact plug system.
