The two component arrangements 100 are contact units 108. The two contact units 108 are simultaneously wall units 154, housing units 156, and cover units 176 of the energy storage units 148 shown in the two figures.

The 2 The component arrangement 100 shown comprises a first component 102 and a second component 104. The first component 102 is a current conducting element 110.

The two components 102 and 104 are mechanically connected to one another by the connecting element 106 and at the same time electrically insulated from one another.

While the 2 shown component arrangement of the cylindrical energy storage unit 182 is round, the one shown in the 3 shown component arrangement 100 of the prismatic energy storage unit 150 is rectangular.

The 2 and 3 indicate that the information in the following 4 to 16 The sectional views shown refer equally to the 2 shown cylindrical or on the 3 shown prismatic design. The 4 to 16 The underlying sections are shown in the respective 2 and 3 Cutting directions indicated by Roman numerals.

The 17 shows a simplified schematic representation of a positioning unit 142, which is used in the execution of the 4 The method outlined is suitable for producing a component arrangement 100 for a 2 to produce the cylindrical energy storage unit 182 shown.

The 18 shows a positioning unit 142 which is suitable for positioning a 3 illustrated component arrangement 100 of a prismatic energy storage unit 150.

The 5 , 7 , 9 , 11 , 13 and 15 show component arrangements 100. The component arrangements 100 are each arranged in a positioning unit 142, which is suitable for producing the respective component arrangement 100 shown. During production, the positioning units 142 are used to position the first component 102 and the second component 104 in the positions desired for the respective component arrangement 100. The positioning units 142 can serve as connecting units 186, since the respective connecting element 106 can be produced, for example, from a flowable mass 139, for example a potting compound 134, between the components 102 and 104 positioned in the desired positions at the respective positioning unit 142.

The 5 , 7 , 9 , 11 , 13 and 15 The first component 102 shown in each case is a current-conducting element 110. The second component 104 shown in each of these figures is a delimiting element 112. The component arrangements 100 shown in each of these figures are contacting units 108. The contacting units 108 can be used on energy storage units 148, for example, simultaneously as a wall unit 154, a housing unit 156 and a cover unit 176. 5 , 7 , 9 , 11 , 13 and 15 each show a contacting unit which has a current-conducting element 110, a demarcation element 112 and a connecting element 106, wherein the current-conducting element 110 and the demarcation element 112 are connected to one another via the connecting element 106.

Each of the 5 , 7 , 9 , 11 , 13 and 15 The current-conducting elements shown in FIG. 1 have a receiving section 114, an extending section 116, and an intermediate section 118 connecting the receiving section to the extending section. The respective receiving section 114 has a receiving section surface 120. The respective extending section 116 has an extending section surface 122. The boundary elements shown in these figures each have two opposing surfaces 124 and 126. They also each have a recess 130 delimited by a recess edge 128.

The boundary element 112 extends between the two surfaces 124 and 126 around the recess 130.

The respective recess 130 extends through the boundary element 112 from one surface 126 to the other surface 124 of the boundary element 112.

From the 5 , 7 , 9 , 11 , 13 and 15 It is clearly visible in each case that a distance 188 between the respective extension section surface 122 of the current-conducting element 110 and the surface 126, which is one of the two opposing surfaces 126 and 124 of the boundary element, which faces the extension section surface 122, is so small that the respective receiving section 114 of the current-conducting element 110 extends through the recess 130 of the contacting unit 108 shown in the respective figure.

The respective current-conducting element 110 and the respective demarcation element 112 are fixed to one another by means of the respective connecting element 106.

The 5 , 7 , 9 , 11 , 13 , and 15 The contacting units 108 shown each have a first connection surface 190 in which the connecting element 106 is connected to the current-conducting element 110. The first connection surface 190 is shown by way of example in the 9 highlighted.

The 5 , 7 , 9 , 11 , 13 and 15 The contacting units 108 shown have a second connection surface 192 in which the connecting element 106 is connected to the delimiting element 112. The second connection surface 192 is shown by way of example in the 7 highlighted.

The 5 , 7 , 9 , 11 , 13 and 15 The contacting units shown each have two further connecting element surfaces 194 and 196. In the further connecting element surfaces, the connecting element 106 is not connected to the current-conducting element 110 or to the delimiting element 112. One connecting element surface 194 of the two further connecting element surfaces 194 and 196 is shown by way of example in the 11 highlighted. A connecting element surface 196 of the two connecting element surfaces 194 and 196 is shown as an example in the 13 highlighted.

In the 15 The first connection surface 190 and the second connection surface 192 are highlighted as examples. Additionally, the two other connecting element surfaces 194 and 196 are also highlighted there.

In the 5 , 7 , 9 , 11 , 13 and 15 It can already be seen from the sections shown that the two connection surfaces 190 and 192 together make up a large part of a total surface 198 of the connecting element 106.

If the contact units 108 shown there in section are round contact units 108 for a 2 schematically illustrated cylindrical energy storage unit 182, can be seen from the 5 , 7 , 9 , 11 , 13 and 15 The two connection surfaces 190 and 192 as well as the two further connecting element surfaces 194 and 196 can be calculated. With little effort, the sum of the two connection surfaces 190 and 192 and also the total surface 198 can be calculated. Of course, the same sizes can also be used for contact units 108 for prismatic energy storage units 150, which are shown in the 3 are illustrated by way of example.

The 6 shows an enlarged section of the 5 . Corresponding excerpts show the 8 , 10 , 12 , 14 and 16 to the previous figure.

The 6 , 8 , 10 , 12 , 14 and 16 are intended to schematically show possibilities of providing the contact units shown therein without any insulating element or with particularly small insulating elements 168.

It may be particularly advantageous if a contacting unit 108 does not have an insulating element 168 ( 14 and 16 ) or one or more relatively small insulating elements 168 ( 6 , 8 , 10 , 12 ). The 6 , 8 , 10 and 12 show indicated insulating elements 168. The insulating elements 168 can only be arranged at the locations indicated there once the contacting units 108 have been removed from the respective positioning unit 142.

Advantageously, the 5 to 12 The contact units 108 shown are each provided entirely without an insulating element. The indicated insulating elements 168 are optional in each case.

However, the insulation elements indicated there are particularly small. In contrast to the 1 Insulating elements 168 are shown in the contact unit 108 in the 5 to 12 are optionally provided only at the edge, whereas the 1 The insulating element 168 shown extends substantially over the entire surface of the contact unit 108 shown there.

From the 5 to 12 It can be seen in each case that the volume occupied by the insulating element indicated therein total occupies, for example, at most approximately 15% of the volume occupied by the current-conducting element 110, the connecting element 106, and the boundary element 112 together. The insulating elements 168 shown therein also do not extend to the receiving sections 114 of the current-conducting elements 110 shown therein.

The 6 , 8 , 10 and 12 show that the insulating element 168 shown therein extends along the surface 126 of the boundary element 112 which faces the extension section surface 122, wherein the respective insulating element 168 extends along a region 202 of the surface 126 which is offset along the surface 126 from a region 200 of the surface 126 which the extension section surface 122 faces.

It can be particularly advantageous in connection with the invention if contacting units 108 are designed in such a way that the emergency The necessity of attaching an insulating element 168 is eliminated. Advantageously, the connecting element 106 can extend further along the surface 126, in particular into a region 202 which is not opposite the extension section surface 122 ( 14 and 16 ).

The 4 illustrates a method for manufacturing a component assembly 100 comprising a first component 102 and a second component 104. The components 102 and 104 are connected to one another via a connecting element 106.

The component arrangement 100 is a contacting unit 108. The first component 102 is a current-conducting element 110. The second component 104 is a demarcation element 112.

The 4 clearly shows that the first component 102, i.e. the current-conducting element 110, has a receiving section 114, an extending section 116 and an intermediate section 118 connecting the receiving section 114 to the extending section 116, wherein the receiving section 114 has a receiving section surface 120 and the extending section 116 has an extending section surface 122.

The 4 also shows that the second component 104, i.e. the boundary element 112, has two opposing surfaces 124 and 126 and a recess 130 delimited by a recess edge 128.

The second component 104 extends between the two surfaces 124 and 126 around the recess 130. The recess 130 extends through the second component 104, from one surface 124 to the other surface 126.

The four in the 4 Figures connected to one another and with arrows schematically show the sequence of the method for producing a component arrangement 100. One of the components 102, 104 is moved relative to the other component 102, 104 such that a distance 132 between the extension section surface 122 of the first component 102 and one of the two opposing surfaces 124 and 126 of the second component 104, which faces the extension section surface 122, is reduced. One of the components 102, 104 is moved relative to the other component 102, 104 such that the receiving section 114 of the first component 102 extends through the recess 130.

Subsequently, the connecting element 106 is manufactured from a potting compound 134 between the components 102 and 104 such that the two components 102 and 104 are secured to one another by the connecting element 106. In the example shown here, the connecting element 106 is a potting element 136.

The receiving portion 114 is a feedthrough portion 138. It extends through the recess 130.

In the 4 In the method illustrated, the connecting element 106 between the components 102 and 104 is manufactured such that the two components 102 and 104 are electrically insulated from each other by the connecting element 106. Commercially available encapsulants 134 are based on electrically insulating plastics or resins.

It would also be possible to manufacture the connecting element between the components in such a way that the two components 102 and 104 are connected by the connecting element 106 with an electrical resistance that can preferably be between 0.1 ohms and 1000 ohms. If electrically conductive additives are added to a potting compound 134, a desired electrical resistance can be achieved with minimal experimental effort.

In the 4 In the example shown of a method for producing a component arrangement 100, the connecting element 106 is produced from a flowable mass 139, which is a potting compound 134.

The 4 The bottom figure shows how the flowable mass 139, i.e. the potting compound 134, is introduced into a cavity 140 adjacent to the two components 102 and 104.

The indicated vessel, from which the flowable mass 139 flows into the cavity 140, is for illustrative purposes only. Of course, the flowable mass 139 could be fed into the cavity 140 in an industrial plant for carrying out the process, for example, from a feed opening, such as a nozzle.

In the 4 In the method illustrated, a positioning unit 142 according to the invention is used. The positioning unit 142 holds the two components 102 and 104 relative to each other in an arrangement 144 desired for the component arrangement 100. It also forms a barrier 146 which delimits the cavity 140 in which the connecting element 106 is produced between the components 102 and 104.

In the 4 In the lowermost illustration, a first component section 204 of the second component 104 and a second component section 206 of the second component 104 are indicated. The first component section 204 is a component section overlaid and/or overlapped by the extension section 116. The second component section 206 is a component section not overlaid and/or overlapped by the extension section 116.

The surface 126 of the second component 104 facing the extension section surface 122 is a surface of the second component 104 lying on the first component section 204.

From the 4 It is also clearly evident that the connecting element 106 can be manufactured, for example by guiding and/or spreading the flowable mass 139 on the second component 104, in such a way that the connecting element 106 on the second component 104 does not extend into the second component section 206.

However, it may be particularly advantageous in connection with the invention if the connecting element 106 is produced, for example by guiding and/or spreading the flowable mass 139 on the second component 104, in such a way that the connecting element 106 extends on the second component 104 into the second component section 206.

This possibility is illustrated by the 7 to 16 for the component arrangements 100 or contact units 108 shown there.

From the overview of the 4 to 16 It will be apparent to those skilled in the art that a cavity extension recess 212 can be provided on a positioning unit 142. The cavity extension recess 212 can serve, in particular, to form a cavity 140 after the positioning of the first component 102 and the second component 104 at the designated positions of the positioning unit 142, which cavity extends into the cavity extension recess 212. During the production of the connecting element 106, a flowable mass 139 can then extend, for example, within the cavity 140 into the cavity extension recess 212 or can be spread out or guided into the cavity extension recess 212, so that the resulting connecting element 106 extends on the second component 104 not only into the first component section 204, but also into the second component section 206.

It may be advantageous if the cavity 146 extends beyond the end of the extension section 116 facing away from the intermediate section 118, for example into a spreading zone 234 which extends beyond the end of the extension section 116 facing away from the intermediate section 118.

It may be advantageous if the flowable mass 139, e.g. the casting compound 134, is introduced into the cavity 140 and guided therein into the spreading zone 234.

In particular, a connecting element 106 formed in this way can have a connecting zone 208 and an insulating zone 210, wherein the connecting zone 208 extends on the second component 104 into the first component section and the insulating zone 210 extends on the second component 104 into the second component section 206.

In the component arrangements 100 shown in the 5 to 16 are each contacting units 108. The first component 102 is the current-conducting element 110. The second component 104 is the demarcation element 112. The first component section 204 is a first demarcation element section 214. The second component section 206 is a second demarcation element section 216.

The 7 , 9 , 11 , 13 and 15 clearly show that in the contacting units 108 shown therein, the delimiting element 112 has a first delimiting element section 214 and a second delimiting element section 216, wherein the first delimiting element section 214 is overlaid and/or overlapped by the extension section 116 and the second delimiting element section 216 is not overlaid and/or overlapped by the extension section 116. The connecting elements 106 shown therein each have a connecting zone 208 and an insulating zone 210, wherein the connecting zone 208 is arranged on the first delimiting element section 214 of the delimiting element 112 and the insulating zone 210 is arranged on the second delimiting element section 216 of the delimiting element 112.

It may be particularly advantageous if a superimposed and/or overlapped surface 218 of the delimiting element, into which all of the delimiting elements superimposed and/or overlapped by one or more extension sections 116 of one or more current conducting elements 110, 111 are incorporated, element sections 214 of the boundary element 112, is at most 90% of an area 220 of the boundary element 112, into which all boundary element sections 214 and 216 are covered by connecting element material. Examples of this are shown in the 19 and 20 shown schematically.

The 19 shows a contact unit 108 for a cylindrical energy storage unit 182 in a schematic representation.

The 20 shows a contact unit 108 for a prismatic energy storage unit 150 in a schematic representation.

In the 19 and 20 the inner surfaces of the two contacting units 108, which, when installed on the respective energy storage unit, face the interior of the energy storage unit, are each facing the viewer.

In the 19 Only one section of the demarcation element, which is covered by the connecting element material, is included in the area of the demarcation element. This section is delimited inwards by the dotted line and outwards by the dashed line. This also applies accordingly in the 20 for the surface of the demarcation element, which includes all demarcation element sections covered by the connecting element material. However, two recesses 130 are provided here, indicated by the dot-dash lines.

Hatched are shown in the 19 and 20 the boundary element sections 214 overlapped by extension sections 116, which are relevant for determining the superimposed and/or overlapped area 218.

• Eine erste Positionierzone 222 zur Positionierung von einem ersten Bauelement 102, das zum Beispiel ein Stromleitelement 110 sein kann, an der jeweiligen Positioniereinheit 142;
• eine zweite Positionierzone 224 zur Positionierung von einem zweiten Bauelement 104, das zum Beispiel ein Abgrenzungselement 112 sein kann, an der jeweiligen Positioniereinheit 142; und
• eine zwischen den jeweiligen Positionierzonen 222 und 224 liegende Barriere 146 für die fließfähige Masse 139. Die fließfähige Masse 139 kann zum Beispiel eine Vergussmasse 134 sein. Die fließfähige Masse 139 kann jeweils zur Herstellung einer Bauelementanordnung 100, insbesondere zur Verbindung der Bauelemente 102 und 104, zwischen die Bauelemente 102 und 104 einbringbar sein.

The six different positioning units 142, which are located in the 5 to 16 shown, each have the following:

• A first positioning zone 222 for positioning a first component 102, which may be, for example, a current-conducting element 110, on the respective positioning unit 142;
• a second positioning zone 224 for positioning a second component 104, which may be, for example, a boundary element 112, on the respective positioning unit 142; and
• a barrier 146 for the flowable mass 139 located between the respective positioning zones 222 and 224. The flowable mass 139 can be, for example, a potting compound 134. The flowable mass 139 can be introduced between the components 102 and 104 in order to produce a component arrangement 100, in particular to connect the components 102 and 104.

The first positioning zone 222 is an inner positioning zone 223.

The second positioning zone 224 is an outer positioning zone 225.

In particular, during the introduction of the flowable mass 139, the barrier 146 can limit a spread of the flowable mass 139 between the components 102 and 104.

The six positioning units 142, which are located in the 5 to 16 are shown, the first positioning zone 222 each has a first contact zone 226, against which the first component 102, for example the current conducting element 110, can be placed on the respective positioning unit 142.

In the 5 to 16 In the positioning units 142 shown, the second positioning zone 224 has a second contact zone 228, against which the second component 104, for example the boundary element 112, can be placed on the respective positioning unit 142.

In the 5 to 16 In each of the positioning units 142 shown, the first positioning zone 222 has a first lateral limiting element 230, by means of which slipping of the first component 102 at the first contact zone 226 relative to the second component 104 can be limited or prevented.

In the 5 to 16 In each of the positioning units 142 shown, the second positioning zone 224 has a second lateral limiting element 232, by means of which slipping of the second component 104 at the second contact zone 228 relative to the first component 102 can be limited or prevented.

The 5 to 16 The positioning units shown can be connected to the 6 , 8 , 10 , 12 , 14 and 16 each of the barriers 146 shown has a non-stick coating 240.

This can in particular contribute to the fact that the component arrangement 100, e.g. the contacting unit 108, can be removed more easily from the positioning unit 142 after its manufacture on the positioning unit 142, because a potting element 136 made of a flowable mass 139, which extends up to the barrier 146, then does not adhere or adheres less firmly to the barrier 146.

In the 13 to 16 In the positioning units 142 shown, the barrier is concave and recessed.

The 5 , 6 , 9 , 10 , 11 , 12 , 13 , 14 , 15 and 16 The positioning units 142 shown each have a barrier section 236 sloping from the second contact zone 228. The sloping barrier section 236 can slope vertically ( 5, 6 and 13 to 16 ) or slope down ( 9 to 12 ).

The positioning unit of the 7 and 8 and the positioning unit of the 15 and 16 The barrier has a non-sloping barrier section 238. In the positioning units according to the 9 , 10 , 11 , 12 As shown in Figures 13 and 14, the barrier 146 each has a sloping barrier section 236. It is immediately apparent that this opens up the possibility of directly producing an insulating zone 210 from a flowable mass 139 used to manufacture the connecting element 106, which extends into a region of the boundary element 112 that does not overlap with the current-conducting element 110.

The terms “sloping”, “sloping” and “not sloping” refer to the main extension plane 242 of the positioning unit 142. The main extension plane 242 is an additional plane in which the second contact zone 228 is located. 6 , 8 , 10 , 12 , 14 and 16 The main extension plane 242 lies perpendicular to the section plane. Therefore, the main extension plane 242 is indicated there only as a line.

The barrier section 236 can slope down in particular transversely to an extension direction 244 of the barrier 146, wherein the extension direction 244 of the barrier 146 can be a direction along which the barrier 146 extends in a ring-shaped manner. The extension direction 244 and its ring-shaped extension are shown in the 17 indicated.
