[0002] Description

[0003] Contact device, contact system, cell contact system and method for mounting the contact system and the cell contact system

[0004] The invention relates to a contact device according to Claim 1, to a contact system according to Claim 10, to a cell contact system according to Claim 12 and to a method for mounting the contact system according to Claim 13.

[0005] The patent application claims the priority of German patent application 102025 106563.2, the disclosure content of which is hereby incorporated by reference.

[0006] WO 2023 / 078917 A1 discloses a plug connector, a plug connector arrangement, and a tool and method for mounting the plug connector arrangement.

[0007] It is the object of the invention to provide an improved contact device, an improved contact system, an improved cell contact system and an improved method for mounting the contact system.

[0008] This object is achieved by means of a contact device according to Claim 1 , a contact system according to Claim 10, a cell contact system according to Claim 12 and a method according to Claim 13. Advantageous embodiments are specified in the dependent claims.

[0009] It has been recognized that it is possible to provide an improved contact device for contacting a flexible conductor foil in a contact system, in particular in a cell contact system of an electrical energy store, by virtue of the contact device having at least one first contact element and a housing with a housing interior. The first contact element has a first connecting section extending along a displacement axis and a foil contact section with a cutting edge arrangement extending at an angle to the first connecting section and connected to the first connecting section. The housing has a first passage opening leading into the housing interior. The housing furthermore has on the inside a raster arrangement with at least one first raster receptacle and at least one second raster receptacle arranged offset at a track distance along the displacement axis with respect to the first raster receptacle. The first contact element can be mounted on the housing along the displacement axis between a first raster position and a second raster position arranged offset along the displacement axis relative to the first raster position. In the first raster position, the foil contact section of the first contact element engages in the first raster receptacle and, in theTE Connectivity Solutions GmbH AMP19310PC 2

[0010] second raster position, the foil contact section of the first contact element engages in the second raster receptacle. Furthermore, in the first raster position and in the second raster position, the first connecting section reaches through the first passage opening.

[0011] This configuration has the advantage that the first contact element can be oriented in a defined way in the housing by means of the contact device such that, in the mounted state of the contact system, only an assigned conductor track of the flexible conductor foil can be contacted in each case by means of the foil contact section. Further conductor tracks are conducted through the contact device without contact being made. For example, the first contact element can be preassembled in the housing in each case in the first raster position or in the second raster position, with the raster arrangement defining the orientation of the foil contact section in a specified manner.

[0012] In a further embodiment, the housing has at least one first foil passage opening, which opens into the housing interior offset with respect to the first passage opening. The first foil passage opening is oriented along the displacement axis in a defined way with respect to the raster arrangement. By means of the first foil passage opening, it is thus possible for the flexible conductor foil to be inserted into the housing interior to be positioned in a defined way in the housing along the displacement axis such that the orientation of the conductor tracks with respect to the raster arrangement is also defined.

[0013] In a further embodiment, the housing has a second foil passage opening which is arranged opposite the first foil passage opening. The second foil passage opening opens into the housing interior. The cutting edge arrangement of the foil contact section of the first contact element is arranged between the first foil passage opening and the second foil passage opening. This configuration has the advantage that the flexible conductor foil can be completely guided through the contact device and one of the conductor tracks of the flexible conductor foil can be contacted in a defined way by means of the first contact element, and that the further conductor tracks of the flexible conductor foil can be conducted through the housing of the contact device without contact being made.

[0014] In a further embodiment, the housing has a foil housing part and a contact housing part, the foil housing part and the contact housing part being connected to each other and surrounding the housing interior at least in some sections. The contact housing part has at least one base section, which is arranged offset with respect to, in particular opposite, the foil housing part. The raster arrangement is arranged on the inside of the base section, wherein the foil contact section of the first contact element is arranged between the rasterTE Connectivity Solutions GmbH AMP19310PC 3

[0015] arrangement and the foil housing part. This configuration has the advantage that the raster arrangement can be produced particularly simply and cost-effectively, for example by means of an injection moulding process or 3D printing. Furthermore, easy demouldability is provided, in particular during production of the contact housing part in the injection moulding process.

[0016] In a further embodiment, the housing has on the inside a guide with at least one first guide receptacle. The first raster receptacle is arranged between the first passage opening and the second raster receptacle, wherein, starting from the first passage opening, the first guide receptacle extends towards the second raster receptacle. The first guide receptacle opens into the first raster receptacle and into the second raster receptacle. The first connecting section of the first contact element is arranged at least in some sections in the first guide receptacle. This configuration has the advantage that, in the mounting of the contact device, the first contact element can be moved particularly easily along the displacement axis between the first raster position and the second raster position without the first contact element tilting. In particular, for example, automated mounting of the contact device is thereby possible.

[0017] In a further embodiment, the raster arrangement has at least one third raster receptacle, wherein the housing has a second passage opening arranged on a side opposite the first passage opening along the displacement axis. The second passage opening opens into the housing interior, wherein the raster arrangement is arranged along the displacement axis between the first passage opening and the second passage opening. The second passage opening is provided, for example, in particular when the flexible conductor foil to be contacted has a greater number of conductor tracks (for example, greater than 5), such that either the flexible conductor foil or the respectively assigned conductor track can be contacted by means of the first contact element from the one side (for example, from the first passage opening) or from the other, opposite side (for example, from the second passage opening). As a result, the contact device can be used particularly flexibly and is also suitable for flexible conductor foils having a higher number of conductor tracks.

[0018] In a further embodiment, the contact device has a second contact element, the second contact element having a first connecting section extending along the displacement axis and a foil contact section with a cutting edge arrangement extending at an angle to the first connecting section and connected to the first connecting section. In particular, for example, the first contact element and the second contact element can be configured structurally identically or identically. Structurally identically is understood as meaning, forTE Connectivity Solutions GmbH AMP19310PC 4

[0019] example, that a length of the first connecting section of the second contact element is changed, for example, compared to a length of the first connecting section of the first contact element. The second contact element can be arranged in the housing in a third raster position, which is offset with respect to the first raster position. In the third raster position, the foil contact section of the second contact element engages in the third raster receptacle and the second connecting section reaches through the second passage opening. Thus, two different conductor tracks of the flexible conductor foil can be contacted, and further conductor tracks are, for example, conducted only through the contact device without said conductor tracks being contacted.

[0020] In a further embodiment, the contact device has a support element, the support element having a second connecting section extending along the displacement axis and a support section which is connected to the second connecting section. The support section is arranged at an angle to the second connecting section. Preferably, the support section extends in a plane at an angle, in particular perpendicularly, to the displacement axis. The support section has an abutment surface on a side facing away from the second connecting section. The support element is spaced apart from the first contact element and engages by means of the support section in one of the raster receptacles. This configuration has the advantage that, for example, the flexible conductor foil is supported on the abutment surface and thus bulging within the contact device can be avoided. This ensures that, by means of the cutting edge arrangement of the first contact element, the conductor track to be contacted can also be pierced in a very precisely defined way in order to contact this conductor track.

[0021] In a further embodiment, the housing has on the inside a latching mechanism with at least one latching element, the latching element extending from the housing into the housing interior and having a latching surface facing the latching mechanism. In the first raster position or in the second raster position, the latching element abuts the first connecting section and secures the first connecting section to the housing when the foil contact section engages in the first raster receptacle or in the second raster receptacle. This configuration has the advantage that the first contact element is secured in all three spatial directions.

[0022] It has been recognized that an improved contact system, in particular a cell contact system for an electrical energy store, can be provided by virtue of the contact system having the above-described contact device and a flexible conductor foil. The flexible conductor foil has at least one first conductor track and a second conductor track arranged offset at a track distance with respect to the first conductor track. The flexible conductor foil isTE Connectivity Solutions GmbH AMP19310PC 5

[0023] introduced into the housing interior. In the first raster position, the first contact element penetrates the first conductor track with the cutting edge arrangement and electrically contacts the first conductor track. In the first raster position, the first contact element is electrically insulated from the second conductor track. In the second raster position, the first contact element penetrates the second conductor track with the cutting edge arrangement and electrically contacts the second conductor track. In the second raster position, the first contact element is electrically insulated from the first conductor track. This configuration has the advantage that the contact system can be used to specifically contact a defined conductor track, for example the first or second conductor track, by means of the first contact element, while the first contact element of the other conductor tracks does not make contact. The further conductor tracks are preferably not contacted in the contact device either, but rather are, for example, conducted through the contact device without contact being made. As a result, the contact system can be used in particular to transmit a signal via a certain conductor track and / or to feed said signal into the latter and / or to tap said signal off from same.

[0024] In a further embodiment, the abutment surface of the support section abuts the flexible conductor foil and supports the flexible conductor foil within the housing interior. The abutment surface is preferably spaced apart from the first conductor track and / or the second conductor track, and a carrier layer of the flexible conductor foil electrically insulates the abutment surface with respect to the conductor track arrangement. This prevents unwanted contacting of the respectively closest conductor track by the support element.

[0025] An improved cell contact system for an electrical energy store, in particular for a traction battery of a vehicle, can be provided in that the cell contact system has a first contact device, a second contact device, a cell connector arrangement with a first cell connector and with at least one second cell connector. The first contact device and the second contact device are each configured as described above. The first cell connector is arranged offset with respect to the second cell connector. The flexible conductor foil is guided through the housing interior of the housing of the first contact device, with the first contact element of the first contact device in the first raster position penetrating the first conductor track with the cutting edge arrangement and electrically contacting the first conductor track. The first connecting section of the first contact element of the first contact device is electrically and mechanically connected, in particular welded, to the first cell connector. The first contact element of the second contact device is arranged in the second raster position and penetrates the second conductor track with the cutting edge arrangement and electrically contacts the second conductor track. The first connecting section of the first contact elementTE Connectivity Solutions GmbH AMP19310PC 6

[0026] of the second contact device is electrically and mechanically connected, in particular welded, to the second cell connector. This configuration has the advantage that a voltage signal originating from the respective cell connector can be transmitted in each case via the first contact element into the respectively assigned conductor track. For example, the identically configured contact device can be used in each case, so that a variety of parts can be kept to a minimum within the cell contact system.

[0027] An improved method for mounting the above-described contact system and / or the abovedescribed cell contact system can be provided by virtue of the contact device, as described above, and a flexible conductor foil being provided. The flexible conductor foil has a conductor track arrangement with a first conductor track and a second conductor track, which is arranged offset with respect to the first conductor track. Depending on the first conductor track or second conductor track to be contacted with the cutting edge arrangement of the first contact element, the first contact element is moved along the displacement axis into the first raster position or into the second raster position and is inserted into the housing, wherein the first connecting section is guided through the first passage opening.

[0028] The flexible conductor foil is introduced into the housing interior with a predefined orientation of the conductor track arrangement with respect to the raster arrangement. The predefined orientation can take place geometrically by means of the housing, for example. In particular, the flexible conductor foil is oriented with respect to the raster arrangement in such a way that the first conductor track or second conductor track to be contacted is arranged at a minimal distance from the associated cutting edge arrangement. The cutting edge arrangement is pushed through the first conductor track or second conductor track to be contacted in such a way that the cutting edge arrangement contacts the first conductor track or the second conductor track. This configuration has the advantage that a mounting method of the contact system comprises particularly few steps and can thus be carried out particularly quickly, easily and cost-effectively, advantageously even in fully automated mode.

[0052] Figure 22 shows a perspective illustration of a partially illustrated contact system according to a third embodiment.

[0053] For ease of understanding, in the figures below reference is made to a coordinate system. The coordinate system has an x axis, a y axis and a z axis. By way of example, the coordinate system here is in the form of a right-handed system.

[0054] Figure 1 shows a perspective illustration of a contact system 10 according to a first embodiment with a contact device 15 in a contact position, and Figure 2 shows a perspective illustration of the contact system 10 shown in Figure 1 with the contact device 15 in a mounting position.

[0055] In addition to the contact device 15, the contact system 10 comprises a flexible conductor foil 20. In Figure 1, the contact device 15 is illustrated by way of example in the contact position. In the contact position of the contact device 15, the flexible conductor foil 20 isTE Connectivity Solutions GmbH AMP19310PC 9

[0056] introduced into the contact device 15 and the contact device 15 contacts the flexible conductor foil 20.

[0057] The flexible conductor foil 20 has a carrier layer 25 and a conductor track arrangement 30. The conductor track arrangement 30 has at least one first conductor track 35 and a second conductor track 40, which is arranged with respect to the first conductor track 35 at a track distance b in the x direction.

[0058] For example, in the embodiment, the conductor track arrangement 30 may have a multiplicity of conductor tracks 35, 40, but, for reasons of simplicity, only the first conductor track 35 and the second conductor track 40 will be discussed below. For example, in Figure 1, the flexible conductor foil 20 is configured with seven first and second conductor tracks 35, 40, the conductor tracks 35, 40 each being arranged offset from one another at the regular track distance b in the x direction. The main direction of extent of the conductor tracks 35, 40 is in the z direction.

[0059] The conductor tracks 35, 40 are electrically insulated from one another by the electrically non-conductive carrier layer 25. The conductor track 35, 40 can in each case be produced from an electrically conductive material, in particular from copper. The conductor track 35, 40 may, for example, be configured to transmit an electrical signal, for example a data signal or electrical power. In particular, a voltage signal or a temperature signal can be transmitted via the conductor track 35, 40.

[0060] In the embodiment, for example, the conductor tracks 35, 40 are embedded in the carrier layer 25, so that the conductor tracks 35, 40 are, for example, completely surrounded circumferentially and are electrically insulated by the carrier layer 25.

[0061] By way of example, the contact device 15 has a first contact element 55 (partially hidden in Figure 1) and a housing 60. The housing 60 has a foil housing part 65 and a contact housing part 75. The contact housing part 75 and the foil housing part 65 engage in one another. The housing 60 surrounds a housing interior 165.

[0062] The contact system 10 is completely mounted in Figure 1 , with the flexible conductor foil 20 being guided, for example completely, through the housing 60, in particular through the foil housing part 65. The contact housing part 75 and the first contact element 55, on the one hand, and the flexible conductor foil 20 and the foil housing part 65, on the other hand, can be moved along a plug-in axis 320 relative to one another between the contactTE Connectivity Solutions GmbH AMP19310PC 10

[0063] position shown in Figure 1 and the mounting position (cf. Figure 2). The plug-in axis 320 is oriented parallel to the y axis.

[0064] In the contact position, the contact housing part 75 is connected in a form-fitting manner to the foil housing part 65 by means of a first form-fitting connection 76. The first form-fitting connection 76 may be, for example, in the form of a first latching connection. In the mounting position (cf. Figure 2), the first form-fitting connection 76 is released and the foil housing part 65 is connected to the contact housing part 75 by means of a second formfitting connection 77 and is held in the mounting position by means of the second form-fit-ting connection 77. The second form-fitting connection 77 may be, for example, in the form of a second latching connection.

[0065] On the side facing away from the contact housing part 75 in the y direction, the foil housing part 65 has, for example, a first housing opening 310. In the mounted state of the contact system 10, the first housing opening 310 is, for example, accessible, but may also be closed by a housing cover (not illustrated in Figures 1 and 2).

[0066] In the mounting position of the contact device 15 (cf. Figure 2), the flexible conductor foil 20 can be introduced into the contact device 15 or removed from the contact device 15.

[0067] Figure 3 shows a perspective illustration of the first contact element 55 of the contact device 15 shown in Figures 1 and 2.

[0068] The first contact element 55 has a first connecting section 80 and a foil contact section 85. In addition, the first contact element 55 may have a connection portion 90. The first connecting section 80 and preferably also the connection portion 90 extend in their main direction of extent along a displacement axis 95, which is oriented parallel to the x axis. For example, the foil contact section 85 may be connected on one side to the first connecting section 80. In the x direction, for example, the connection portion 90 is connected to the first connecting section 80 on a side facing away from the foil contact section 85.

[0069] The connection portion 90 may, for example, be plate-like and extend substantially in an xz plane. For example, the connection portion 90 has a connection surface 100, which is arranged, for example, on an underside which is illustrated in Figure 3 and faces away from the foil housing part 75, for example. At the connection surface 100, the connection portion 90 can be electrically connected to another electrical component, for example inTE Connectivity Solutions GmbH AMP19310PC 11

[0070] an integrally bonded manner, for example by means of a welding process or by means of a soldering process.

[0071] The first connecting section 80 is substantially plate-like. For example, a step may be arranged at a transition 105 between the first connecting section 80 and the connection portion 90. By way of example, in the embodiment, the first connecting section 80 is oriented parallel to the connection portion 90 by means of the step at the transition 105.

[0072] The first connecting section 80 has a protrusion receptacle 110 extending substantially along the displacement axis 95 and thus in the x direction in the embodiment. The protrusion receptacle 110 is elongated and configured as a passage opening in the y direction in the first connecting section 80. The protrusion receptacle 110 can extend substantially completely over the first connecting section 80, by way of example along the displacement axis 95.

[0073] The foil contact section 85 is oriented at an angle, preferably perpendicularly, to the displacement axis 95 and can be connected to the first connecting section 80. By way of example, in Figure 3, the foil contact section 85 is connected on the underside to the first connecting section 80.

[0074] In the embodiment, for example, the foil contact section 85 and the first connecting section 80, and preferably the connection portion 90, are made integrally and from the same electrically conductive material. In particular, for example, the first contact element 55 can be produced from a thin-walled sheet-metal material, for example by means of a punching and bending process.

[0075] On a side facing away from the first connecting section 80, the foil contact section 85 has a cutting edge arrangement 115 with at least one first cutting edge element 120. In addition, the cutting edge arrangement 115 may have a second cutting edge element 125. Also, as illustrated in Figure 3, the cutting edge arrangement 115 can have two first cutting edge elements 120, with the second cutting edge element 125 being formed in each case spaced apart in the z direction between the two first cutting edge elements 120.

[0076] In the not yet installed state, in particular in the mounting position, both the first cutting edge element 120 and the second cutting edge element 125 are oriented substantially rectilinearly, running parallel to the y axis. For example, a tip 130 of the respective cuttingTE Connectivity Solutions GmbH AMP19310PC 12

[0077] edge element 120, 125 is arranged on a side facing away from the first connecting section 80.

[0078] On a side facing away from the cutting edge arrangement 115, the foil contact section 85 may have a stop 131, the stop 131 being plate-like and extending in a direction facing away from the cutting edge arrangement 115, in Figure 3 downwards, so that at least the stop 131 is arranged level with the protrusion receptacle 110.

[0079] Figure 4 shows a top view of the first contact element 55 shown in Figure 3.

[0080] It can clearly be seen in Figure 4 that the protrusion receptacle 110 extends along the displacement axis 95 completely as far as the foil contact section 85 and the stop 131 and one end of the protrusion receptacle 110 is arranged directly on the foil contact section 85.

[0081] Also, the protrusion receptacle 110 may extend slightly, for example, via the transition 105 into the connection portion 90. By means of the protrusion receptacle 110, the first connecting section 80 is thus formed in two parts and extends by means of the two bars 141 , 142 along the x axis. The two bars 141 , 142 are formed on both sides in the z direction of the protrusion receptacle 110 and, by way of example, have a mutually identical width in the z direction.

[0082] Figure 5 shows a perspective illustration of the housing 60 in the contact position.

[0083] For reasons of clarity, the illustration of the first contact element 55 and of the flexible conductor foil 20 is omitted in Figure 5.

[0084] The housing 60 has, for example, a first long side 135 and a second long side 140 arranged opposite in the z direction, the two long sides 135, 140 extending along the displacement axis 95. Furthermore, at the respective end, the housing 60 has a first short side 145 and a second short side 150, the two short sides 145, 150 connecting the two long sides 135, 140 to each other. The housing 60 has, for example, a cuboidal basic shape.

[0085] For example, the housing 60, in particular in the foil housing part 65 on the first long side 135, has a first foil passage opening 155 and preferably a second foil passage opening 160, arranged opposite the first foil passage opening 155 in the z direction, on the second long side 140, the second foil passage opening 160 being indicated by way of example byTE Connectivity Solutions GmbH AMP19310PC 13

[0086] dashed lines in Figure 5. The foil passage opening 155, 160 is slotted and opens into the housing interior 165 of the housing 60. The foil passage openings 155, 160 are, for example, slotted and preferably formed in the foil housing part 65 at the same height in the y direction.

[0087] On the first short side 145, the housing 60 has a first passage opening 170. The first passage opening 170 opens into the housing interior 165 in a manner offset with respect to the foil passage opening 155, 160. For example, a second passage opening 175 (illustrated by dashed lines) may be formed in the housing 60 along the displacement axis 95 opposite the first passage opening 170 on the second short side 150, the second passage opening 175 likewise extending along the displacement axis 95 and opening into the housing interior 165.

[0088] In the contact position, the first passage opening 170 and preferably also the second passage opening 175 are formed in two parts, such that the first passage opening 170 has, for example, a first opening section 180 and a second opening section 185 arranged offset with respect to the first opening section 180 in the z direction. A foil housing bar 190 of the foil housing part 65 may be arranged between the first opening section 180 and the second opening section 185, said foil housing bar dividing the first passage opening 170 and / or the second passage opening 175 into the first opening section 180 and the second opening section 185.

[0089] Figure 6 shows a perspective illustration of the contact housing part 75 of the housing 60 shown in Figure 5.

[0090] The contact housing part 75 has a base section 195, the base section 195 extending substantially in an xz plane. Laterally, the base section 195 is delimited by the long sides 135, 140. The base section 195 is arranged, for example, opposite the foil housing part 65.

[0091] At the base section 195, the housing 60 has, for example, a raster arrangement 200. The raster arrangement 200 can be regularly configured, for example. The foil passage opening 155, 160 is oriented along the displacement axis 95 in a defined way with respect to the raster arrangement 200.

[0092] The raster arrangement 200 has at least one first raster receptacle 205 and at least one second raster receptacle 210. Preferably, the raster arrangement 200 has a multiplicity of raster receptacles 205, 210, 215, it being possible for a number of the raster receptaclesTE Connectivity Solutions GmbH AMP19310PC 14

[0093] 205, 210, 215 to correspond to a number of conductor tracks 35, 40 of the conductor track arrangement 30. For example, the arrangement of the raster receptacles 205, 210, 215 correlates with a possible raster position 1P, ..., 14P of the first contact element 55 in the housing 60.

[0094] The first raster receptacle 205 is arranged, for example, closest to the first short side 145, the first raster receptacle 205, for example, defining a first raster position, which is referred to as 1 P in Figure 6, below.

[0095] The second raster receptacle 210 is arranged spaced apart with respect to the first raster receptacle 205 from the first short side 145 towards the second short side 150. For example, the first raster receptacle 205 and the second raster receptacle 210 are arranged spaced apart along the displacement axis 95 at the track distance b of the first conductor track 35 from the second conductor track 40. A second raster position 2P of the first contact element 55 is defined with the second raster receptacle 210.

[0096] In order to separate the raster receptacles 205, 210, 215 from one another in the x direction, a raster protrusion 220 extends in the y direction starting from the base section 195. The raster protrusion 220 may, for example, have a rectangular profile on the outside, with the raster protrusion 220 preferably extending parallel to the y axis. For example, in the embodiment in Figure 6, a multiplicity of raster protrusions 220 are arranged in a protrusion row 225, each extending away from the base section 195. For example, the raster protrusions 220 are substantially identical to one another, with it being possible for a deviation to be made from the identical configuration, in particular in the region of the first short side 145 and the second short side 150, to the effect that the raster protrusion 220 extends substantially completely between the corresponding short side 145, 150 and the first raster receptacle 205 to be formed or, in the embodiment, for example, the fourteenth raster receptacle at the fourteenth raster position 14P.

[0097] Figure 7 shows a top view of the contact housing part 75 shown in Figure 6.

[0098] In addition to the multiplicity of raster receptacles 205, 210, the raster arrangement 200 may, for example, also have a third raster receptacle 215. The possible raster positions have each been referred to as nP for the sake of clarity in Figure 6, with n being a natural number and representing the respective raster position. In total, in Figure 6, the raster arrangement 200 has, for example, fourteen possible raster positions 1 P, ... , 14P for the first contact element 55.TE Connectivity Solutions GmbH AMP19310PC 15

[0099] In the following, the first raster receptacle 205 is described by way of example, the raster receptacles 205, 210, 215 of the raster arrangement 200 being identical to one another. That which has been explained for the first raster receptacle 205 likewise also applies correspondingly to the further raster receptacles 210, 215.

[0100] The first raster receptacle 205 is elongated and extends in its main direction of extent at an angle, preferably perpendicularly, to the displacement axis 95. The first raster receptacle 205 is furthermore open towards the housing interior 165 and is delimited in the x direction in each case by a raster protrusion 220 arranged between the first raster receptacle 205 and the closest second raster receptacle 210 or on the closest short side 145, 150. The raster protrusion 220 is, for example, cuboidal. In the z direction, the raster receptacle 205, 210, 215 is configured at least in some sections correspondingly, preferably substantially identically, to the foil contact section 85 both in the x and in the z direction.

[0101] On an outer circumferential side of the raster protrusion 220, the raster protrusion 220 has a first to fourth protrusion side surface 230, 235, 240, 245.

[0102] A latching tab 151 may be arranged on the first short side 145 and / or on the second short side 150.

[0103] Figure 8 shows a detail A, which is marked in Figure 7, of the contact housing part 75 shown in Figure 7.

[0104] The protrusion side surfaces 230, 235, 240, 245 are each of planar form, with, for example, the first protrusion side surface 230 and the third protrusion side surface 240 extending in a yz plane. For example, in the case of two raster protrusions 220 arranged adjacent in the x direction, the first protrusion side surface 230 and the third protrusion side surface 240 are arranged opposite each other, with the respectively assigned raster receptacle 205, 210, 215 extending in the x direction between the first protrusion side surface 230 of a raster protrusion 220 and the third protrusion side surface 240 of a closest raster protrusion 220 and being defined in the x direction by the first protrusion side surface 230 and the third protrusion side surface 240.

[0105] The housing 60, in particular the contact housing part 75, furthermore has a guide 250. The guide 250 is configured to define a position of the first contact element 55 in the z direction without, in particular, the first contact element 55 being able to rotate by a largerTE Connectivity Solutions GmbH AMP19310PC 16

[0106] angular range about the y axis. In particular, such a rotation could lead to a tilting or blocking of the first contact element 55 in the contact housing part 75 when positioning the first contact element 55 in the contact housing part 75.

[0107] For example, the guide 250 has a first guide receptacle 255 and preferably a second guide receptacle 260, the first guide receptacle 255 and the second guide receptacle 260 being spaced apart from each other in the z direction. In the embodiment, by way of example, the first guide receptacle 255 is connected on the inside to the first long side 135. Opposite in the z direction, the second guide receptacle 260 is arranged, for example, on the inside adjoining the second long side 140 of the housing 60, the second guide receptacle 260 and the first guide receptacle 255 extending parallel to each other in the x direction. For example, the protrusion row 225 with the raster protrusions 220 is arranged between the first guide receptacle 255 and the second guide receptacle 260.

[0108] The first guide receptacle 255 and the second guide receptacle 260 are, for example, recessed with respect to a protrusion upper side 265 of the respective raster protrusion 220 and extend in the y direction in the direction of the base section 195.

[0109] The first guide receptacle 255 and the second guide receptacle 260 open into the raster receptacles 205, 210, 215.

[0110] Figure 9 shows a side view of the contact housing part 75 of the housing 60 shown in Figures 6 to 8.

[0111] The housing 60, in particular the contact housing part 75, has a latching mechanism 280. The latching mechanism 280 is arranged, for example, on the inside of the contact housing part 75 and has an arrangement of latching elements 285. The latching element 285 is preferably arranged on the inside of the first long side 135 and / or of the second long side 140 of the contact housing part 75. The latching element 285 extends into the housing interior 165 and has a latching surface 290 on a side facing the raster arrangement 200, in particular the base section 195. The latching surface 290 may, for example, be of planar form and extend in an xz plane. Preferably, a distance between the guide protrusion upper side 275 and the latching surface 290 substantially corresponds to a material thickness of the first connecting section 80.

[0112] Figure 10 shows a perspective illustration of the contact housing part 75 of the housing 60 with the first contact element 55 inserted.TE Connectivity Solutions GmbH AMP19310PC 17

[0113] In Figure 10, the first contact element 55 is inserted, for example, in the first raster position 1 P, wherein, in the first raster position 1 P, the foil contact section 85 engages in the first raster receptacle 205 of the raster arrangement 200. Furthermore, the latching mechanism 280 secures the first contact element 55 to the contact housing part 75 of the housing 60.

[0114] For example, the first connecting section 80 reaches with the first bar 141 through the first opening section 180 of the first passage opening 170 and with the second bar 142 through the second opening section 185 of the first passage opening 170. Furthermore, the connection portion 90 is arranged outside the housing interior 165. The protrusion receptacle 110 is penetrated by the latching tab 151. The first bar 141 is arranged in the first guide receptacle 255 and the second bar 142 is arranged in the second guide receptacle 260.

[0115] Figure 11 shows a sectional view along a sectional plane C-C shown in Figure 10 of the perspective illustration of the contact housing part 75 and the first contact element 55, shown in Figure 10.

[0116] For example, outside the housing interior 165, a first partial region 295 of the first connecting section 80 and a second partial region 300 of the first connecting section 80 are arranged in the housing interior 165.

[0117] It can clearly be seen in Figure 11 how the foil contact section 85 is held in the first raster receptacle 205 by the first protrusion side surface 230 and the third protrusion side surface 240 arranged opposite thereto. Furthermore, the raster protrusion 220 reaches through the protrusion receptacle 110.

[0118] Figure 12 shows a sectional view along a sectional plane D-D shown in Figure 10 through the contact housing part 75 shown in Figure 10 and the first contact element 55 in the first raster position 1 P.

[0119] Furthermore, in the y direction, the latching mechanism 280 secures the first contact element 55 in the y direction by the latching surface 290 lying against the upper side of the second partial region 300 of the first connecting section 80.TE Connectivity Solutions GmbH AMP19310PC 18

[0120] On the underside, the first connecting section 80 rests in each case on the base section 195, so that the position in the y direction is fixed in a defined way by the latching mechanism 280 and the base section 195.

[0121] Figure 13 shows a sectional view along a sectional plane B-B shown in Figure 10 through the contact housing part 75 shown in Figure 10 and the first contact element 55 in the first raster position 1 P in an unmounted state.

[0122] In the z direction, the first connecting section 80 lies with the first bar 141 and the foil contact section 85 against the inside of the first long side 135. Opposite in the z direction, the second bar 142 and the foil contact section 85 lie against the second long side 140. Furthermore, the stop 131 of the foil contact section 85 protrudes on the underside beyond the connecting section 80, so that the first protrusion side surface 230 and the third protrusion surface 240 are contacted particularly far in the y direction towards the base section 195 by the foil contact section 85 and in particular the stop 131.

[0123] Figure 14 shows a perspective illustration of the contact housing part 75 of the housing 60 and of the first contact element 55 in the second raster position 2P.

[0124] The illustration shown in Figure 14 substantially corresponds to the illustrations shown in Figures 10 to 13, but the first contact element 55 is pushed into the housing interior 165 by the track distance b relative to the first contact element 55 shown in Figure 10, so that the foil contact section 85 engages in the second raster receptacle 210 of the raster arrangement 200. Thus, the second partial region 300 is enlarged relative to the first partial region 295 of the first connecting section 80, and the connection portion 90 is arranged slightly offset in the x direction.

[0125] The further fixations, as explained in Figures 11 to 13, in order to fix the first contact element 55 in all spatial directions x, y, z correspond to the fixation explained in Figures 1 to 13.

[0126] Figure 15 shows a perspective illustration of the contact housing part 75 of the housing 60 and of the first contact element 55, but the first contact element 55 is in a fifth raster position 5P. For this purpose, for example, the first connecting section 80 is substantially completely inserted into the housing interior 165 and the foil contact section 85 engages in a fifth raster receptacle of the raster arrangement 200. Thus, the connection portion 90 isTE Connectivity Solutions GmbH AMP19310PC 19

[0127] arranged offset in relation to Figure 10 in the x direction towards the contact housing part 75.

[0128] In order to approach the further raster positions 6P to 14P, for example, the first contact element 55 and the first connecting section 80 may be elongated or, for example, may be inserted opposite in the x direction. It is also possible that, in particular in the region of the sixth to ninth raster position 6P to 9P, only one such adapted first contact element 55 may be used to contact the corresponding conductor track 35, 40, or a positioning of the foil contact section 85 in the sixth to ninth raster position 6P to 9P is omitted.

[0129] Figure 16 shows a sectional view along the sectional plane B-B shown in Figure 10 through the foil housing part 65.

[0130] The foil housing part 65 has a first housing opening 310, a second housing opening 311 and a foil housing wall 340, which is formed running around the circumference and extends between the first housing opening 310 and the second housing opening 311. The first housing opening 310 is arranged on a side of the foil housing part 65 facing away from the contact housing part 75. The second housing opening 311 is arranged lying opposite in the y direction with respect to the first housing opening on a side of the foil housing part 65 facing the contact housing part 75. The first foil passage opening 155 and preferably the second foil passage opening 160 are arranged between the first housing opening 310 and the second housing opening 311. In the z direction between the first foil passage opening 155 and the second foil passage opening 160, a receiving region 325 extends in the first housing interior 165, into which receiving region preferably at least one of the two foil passage openings 155, 160 opens.

[0131] A bar arrangement 315 is arranged at the first housing opening 310, the bar arrangement extending substantially in the y direction and thus along a plug-in axis 320. The plug-in axis 320 is oriented parallel to the y axis. The bar arrangement 315 may extend, for example, starting from the first housing opening 310 towards a receiving region 325. However, the bar arrangement 315 may also extend beyond the receiving region 325 in the y direction towards the second housing opening 311 , the bar arrangement 315, as shown in Figure 16, being interrupted in the region of the receiving region 325.

[0132] The bar arrangement 315 may comprise at least one first housing bar 330 and preferably at least one second housing bar 335. Each of the housing bars 330, 335 extendsTE Connectivity Solutions GmbH AMP19310PC 20

[0133] substantially in the y direction along the plug-in axis 320, with the result that the housing bars 330, 335 are oriented substantially parallel to one another.

[0134] The first housing bar 330 is arranged on the inside closest to a foil housing wall 340 of the foil housing part 65 on a side facing the first foil passage opening 155. The second housing bar 335 is arranged on the inside with respect to the first housing bar 330. Preferably, at least two second housing bars 335 arranged next to one another are provided. By way of example, the first housing bar 330 ends spaced apart from the first housing opening 310 in the y-direction, whereas, by contrast, for example, the second housing bar 335 is extended, for example, as far as the first housing opening 310.

[0135] For example, the first housing bar 330, together with the second housing bar 335 and the foil housing wall 340, delimits a bending space 345 adjacent to the first housing opening 310. Furthermore, the bending space 345 extends in the y direction in the foil housing part 65 between the first housing opening 310 and the end of the first housing bar 330 that faces the first housing opening 310. For example, the bending space 345 directly adjoins the inside of the foil housing wall 340 in the z direction. Furthermore, on the inside, on the side facing away from the foil housing wall 340, the bending space 345 is delimited by the second housing bar 335.

[0136] On the inside, the first housing bar 330 and the second housing bar 335 arranged closest on the inside with respect to the first housing bar 330 delimit a first cutting edge receptacle 350. The first cutting edge receptacle 350 and the receiving region 325 open into each other. The first cutting edge receptacle 350 extends, starting from the receiving region 325, along the plug-in axis 320 towards the foil housing wall 340 in a y direction facing away from the contact housing part 75 and opens into the bending space 345.

[0137] A second cutting edge receptacle 355, which is formed parallel to the first cutting edge receptacle 350, is arranged on the inside between the two second housing bars 335 arranged next to one another. The second cutting edge receptacle 355 extends substantially in the y direction, starting from the receiving region 325, towards the third housing opening 310.

[0138] Figure 17 shows a sectional view along a sectional plane E-E shown in Figure 1 through the contact system 10 shown in Figure 1.TE Connectivity Solutions GmbH AMP19310PC 21

[0139] The foil housing part 65 is arranged in the contact position and, at the second housing opening 311 , the contact housing part 75 engages in the foil housing part 65.

[0140] For example, the flexible conductor foil 20 extends completely through the housing interior 165 of the housing 60, wherein, in the mounted state of the contact system 10, the foil housing part 65 is connected with a form fit to the contact housing part 75 by means of the latching connection. For example, the foil housing part 65 is pushed onto the contact housing part 75 along the plug-in axis 320 in such a way that the contact housing part 75 and the foil housing part 65 engage in each other.

[0141] Furthermore, in the fully mounted state, the flexible conductor foil 20 is preferably completely conducted through the receiving region 325 between the first foil passage opening 155 and the second foil passage opening 160.

[0142] In the mounted state of the contact system 10, the first cutting edge element 120 reaches with a first cutting edge subsection 360 through the flexible conductor foil 20, for example in the region of the first conductor track 35, and by means of the first cutting edge subsection 360 in each case contacts the assigned conductor track 35, 40 both electrically and mechanically. Furthermore, the first cutting edge subsection 360 protrudes through the receiving region 325 and engages rectilinearly in the first cutting edge receptacle 350.

[0143] On the side facing the first housing opening 310, a second cutting edge subsection 365 of the first cutting edge element 120 protrudes over the first housing bar 330 and out of the first cutting edge receptacle 350. In this case, the second cutting edge subsection 365 lies against the first housing bar 330 on the side facing the first housing opening 310.

[0144] For example, the second cutting edge subsection 365 may be pressed against the first housing bar 330. Furthermore, the second cutting edge subsection 365 protrudes into the bending space 345 and, for example, is guided outwards in the region of the bending space 345 towards the foil housing wall 340. Adjacent to the tip 130 of the first cutting edge element 120, the second cutting edge subsection 365 overlaps the first housing bar 330 in the y direction.

[0145] The second cutting edge element 125 protrudes through the receiving region 325 and contacts the assigned conductor track 35, 40. Furthermore, the second cutting edge element 125 protrudes into the second cutting edge receptacle 355, the second cutting edgeTE Connectivity Solutions GmbH AMP19310PC 22

[0146] element 125 also extending rectilinearly substantially along the plug-in axis 320 in the mounted state.

[0147] In the first raster position 1 P, the first contact element 55 is electrically insulated from the second conductor track 40 by means of the carrier layer 25.

[0148] Corresponding to the contacting of the first conductor track 35 in the first raster position 1 P, contacting of the second conductor track 40 in the second raster position 2P or of the further conductor tracks 35, 40 in the further raster positions 3P, ... , 14P also takes place. In this case, the first contact element 55 is in each case electrically insulated from the other non-contacted conductor tracks 35, 40 by the carrier layer 25.

[0149] Figure 18 shows a flow diagram of a method for mounting the contact system 10 shown in Figures 1 to 17.

[0150] In a first mounting step 405, the contact housing part 75, the first contact element 55, the foil housing part 65 and the flexible conductor foil 20 are provided. In addition, a tool system, not illustrated, is provided.

[0151] In a second mounting step 410, which is carried out following the first mounting step 405, the first contact element 55 is introduced along the plug-in axis 320 into the housing interior 165 and the foil contact section 85 is oriented along the displacement axis 95. For example, above the latching mechanism 280 and the raster arrangement 200, the first contact element 55 can be oriented along the displacement axis 95 such that the first contact element 55, in particular the foil contact section 85, is oriented in a way corresponding to the desired raster position 1P, ..., 14P.

[0152] In a third mounting step 415, following the second mounting step 410, the first contact element 55 is introduced along the plug-in axis 320 into the housing interior 165 according to a defined orientation, until the underside of the first connecting section 80 lies against the guide protrusion upper side 275 and the latching mechanism 280 lies with the latching surface 290 against the upper side of the first connecting section 80. Furthermore, the foil contact section 85 correspondingly engages in the respectively assigned raster receptacle 205, 210, 215 of the raster arrangement 200.

[0153] In this position, the first contact element 55 is fixed in the housing interior 165.TE Connectivity Solutions GmbH AMP19310PC 23

[0154] In a fourth mounting step 420 following the third mounting step 415, the flexible conductor foil 20 is conducted through the receiving region 325 via the first foil passage opening 155 and the second foil passage opening 160. In this case, by means of the geometric configuration of the first and / or second foil passage opening 155, 160, the flexible conductor foil 20 is oriented along the x axis relative to the raster arrangement 200, for example by lateral guidance of the flexible conductor foil 20 at the first and / or second foil passage opening 155, 160.

[0155] Furthermore, the contact housing part 75 and the foil housing part 65 are inserted into each other and brought into the mounting position.

[0156] The contact housing part 75 and the foil housing part 65 can either be inserted into each other in time before the introduction of the flexible conductor foil 20 or in time after the introduction of the flexible conductor foil and moved into the mounting position.

[0157] In a fifth mounting step 425 following the fourth mounting step 420, the foil housing part 65, together with the flexible conductor foil 20 conducted through it, is moved from the mounting position along the plug-in axis 320 onto the fitted contact housing part 75 to an extent until the cutting edge arrangement 115 penetrates / pierces the assigned conductor track 35, 40 of the flexible conductor foil 20 and contacts the assigned conductor track 35, 40 both electrically and mechanically.

[0158] In a sixth mounting step 430 following the fifth mounting step 425, the foil housing part 65 reaches the contact position, wherein, in the end position, the raster arrangement 200 connects the foil housing part 65 to the contact housing part 75 with a form fit.

[0159] In order to push the foil housing part 65 and the contact housing part 75 onto each other in the fourth and fifth mounting steps 420, 425, the tool system, for example, can be attached to the foil housing part 65. For example, in a sixth mounting step 430, while the foil housing part 65 and the contact housing part 75 are moved towards each other along the plug-in axis 320, the tip 130 of the first cutting edge element 120 runs onto a bending surface of the tool and is bent outwards in the direction of the foil housing wall 340 into the bending space 345 by an oblique configuration of the bending surface, in particular a curved configuration of the bending surface of the tool.

[0160] In a seventh mounting step 435 following the sixth mounting step 430, the tool is removed.TE Connectivity Solutions GmbH AMP19310PC 24

[0161] In an eighth mounting step 440 following the seventh mounting step 435, for example, the connection portion 90 is connected, for example with an integral bond, to another component, in particular by means of a welding process, for example an ultrasonic welding process or a laser welding process.

[0162] By means of the foil passage opening 155, 160, it is thus possible for the flexible conductor foil 20 to be inserted into the housing interior 165 to be positioned in a defined way in the housing 60 along the displacement axis 95 such that the orientation of the conductor tracks 35, 40 with respect to the raster arrangement 200 and the corresponding raster positions 1 P, ... , 14P is also defined.

[0163] Figure 19 shows a schematic illustration of a contact system 10 according to a second embodiment.

[0164] In the embodiment, the contact system 10 is configured as a cell contact system 10 and is substantially identical to the contact system 10 explained in Figures 1 to 17 and can be produced by means of the mounting method described in Figure 18. Only the differences between the contact system 10 according to the second embodiment, shown in Figure 19, and the contact system 10 according to the first embodiment, shown in Figures 1 to 17, will be discussed below.

[0165] In the embodiment, the contact system 10 has a plurality of contact devices 15, for example a first contact device 500 and a second contact device 505. In addition, a third contact device 510 may also be provided in Figure 19, the first to third contact devices 500, 505, 510 being formed identically to the contact device 15 shown in Figures 1 to 17 and, in particular, that which is explained in Figures 1 to 17 applying equally.

[0166] Furthermore, the contact system 10 has a cell connector arrangement 515, the cell connector arrangement 515 having, for example, a first cell connector 520 and a second cell connector 525 and, for example, a third cell connector 530. The cell connectors 520, 525, 530 are configured, for example, to connect pole terminals of energy storage cells of an electrical energy store to one another in terms of electrical power.

[0167] For example, the connection portion 90 of the first contact element 55 of the first contact device 500 is connected, for example, with an integral bond and electrically to the first cell connector 520. In an analogous manner, for example, the connection portion 90 of the first contact element 55 of the second contact device 505 is connected to the second cellTE Connectivity Solutions GmbH AMP19310PC 25

[0168] connector 525 and the connection portion 90 of the first contact element 55 of the third contact device 510 is connected to the third cell connector 530.

[0169] The first contact element 55 produces, for example, in the first contact device 500, an electrical connection to the first conductor track 35, since, for example, the first contact element 55 is situated in the first contact device 500 in the first raster position 1 P.

[0170] The second contact device 505 is mounted in such a way that the first contact element 55 is arranged in the second raster position 2P. For example, the foil contact section 85 contacts the second conductor track 40 of the flexible conductor foil 20 by means of the cutting edge arrangement 115.

[0171] Likewise, by means of the third contact device 510, a third conductor track 535 of the flexible conductor foil 20 can therefore also be contacted by the first contact element 55 of the third contact device 510, so that, in each case depending on the raster position 1 P, ..., 14P, the first contact element 55 produces an electrical connection between the assigned cell connector 520, 525, 530 and the correspondingly assigned conductor track 35, 40, 535.

[0172] Thus, by means of the respective conductor track 35, 40, 535, information about an electrical voltage applied to the respective cell connector 520, 525, 530 can be transmitted.

[0173] Figure 20 shows a perspective illustration of a contact system 10 according to a third embodiment in a partially mounted state.

[0174] The contact system 10 is substantially identical to the contact system 10 explained in Figures 1 to 17. Only the differences between the contact system 10 according to the third embodiment, shown in Figure 20, and the contact system 10 according to the first embodiment, shown in Figures 1 to 17, will be discussed below. In particular, however, reference is also made here to the fact that the contact system 10 according to the third embodiment, shown in Figure 20, may be part of the contact system 10 according to the second embodiment, shown in Figure 19.

[0175] The contact system 10 shown in Figure 20 has a support element 600 in addition to the first contact element 55 and the contact housing part 75. The support element 600 is arranged in the x direction opposite the first contact element 55 and engages in the housing interior 165 via the second passage opening 175. The support element 600 isTE Connectivity Solutions GmbH AMP19310PC 26

[0176] substantially identical to the first contact element 55. However, the foil contact section 85 is adapted in relation to the first contact element 55.

[0177] Figure 21 shows a perspective illustration of the support element 600, shown in Figure 20, of the contact system 10 shown in Figure 20.

[0178] The support element 600 is substantially identical to the first contact element 55, and therefore only the differences of the support element 600 in relation to the first contact element 55 will be discussed below. In addition to a second connecting section 605, the support element 600 has a support section 610, the support section 610 being similar to the foil contact section 85 of the first contact element 55. The second connecting section 605 may be identical to the first connecting section 80 of the first contact element 55. In addition, the support element 600 may also have a further connection portion 615, it being possible for the further connection portion 615 to be identical to the connection portion 90 of the first contact element 55.

[0179] The support section 610 is essentially a foil contact section 85 which is shortened in the vertical direction. For example, on a side facing away from the second connecting section 605, the support section 610 has an abutment surface 620, said abutment surface 620 being able to be oriented, for example, parallel to the flexible conductor foil 20. Also, for example, the abutment surface 620 extends in planar form, for example in an xz plane, and can thus also be formed parallel to the base section 195 of the contact housing part 75.

[0180] The support section 610 is shortened in particular in the y direction in such a way that, in the mounted state of the support element 600 (cf. Figure 20), the abutment surface 620 does not engage in the cutting edge receptacles 350, 355 and is thus arranged below the cutting edge arrangement 115 in the y direction. For example, however, the abutment surface 620 may be arranged at least above and thus in the y direction between the housing bars 330, 335 and the protrusion upper side 265. Preferably, in the contact position, the abutment surface 620 is arranged approximately level with the receiving region 325.

[0181] In the mounted state, analogously to the first contact element 55, the support element 600 can be inserted in the second mounting step 410 opposite the first contact element 55 in such a way that the support section 610 engages in an assigned raster receptacle 205, 210, 215, which is offset with respect to the second passage opening 175 towards the foil contact section 85.TE Connectivity Solutions GmbH AMP19310PC 27

[0182] In the mounted state of the contact system 10, the abutment surface 620 lies on the underside on the flexible conductor foil 20, on the side facing the contact housing part 75, and prevents the flexible conductor foil 20 from bulging downwards.

[0183] Figure 22 shows a perspective illustration of a partially illustrated contact system 10 according to a third embodiment.

[0184] The contact system 10 is substantially identical to the contact system 10 shown in Figures 1 to 17. Only the differences between the contact system 10, shown in Figure 22, and the contact system 10 according to the first embodiment, shown in Figures 1 to 17, will be discussed below.

[0185] It is furthermore noted that the contact system 10 shown in Figure 22 can be essentially mounted and produced by the method described in Figure 18.

[0186] In addition to the first contact element 55, the contact system 10 has a second contact element 700, the second contact element 700, for example, being identical to the first contact element 55.

[0187] The second contact element 700 is arranged opposite the first contact element 55 in the x direction, with the foil contact section 85 of the first contact element 55 being spaced apart from the foil contact section 85 of the second contact element 700 in the x direction. For example, the second contact element 700 may be arranged in the housing interior 165 of the housing 60, in particular the contact housing part 75, in such a way that the foil contact section 85 of the first contact element 55 engages in the third raster receptacle 215 (third raster position 3P) or a further (free) raster receptacle of the raster arrangement 200. As shown in Figure 22, the foil contact section 85 of the second contact element 700 is arranged in an eleventh raster position 11 P. Analogously to the fixation of the first contact element 55, described in Figures 1 to 17, the second contact element 700 is also fixed to the contact housing part 75.

[0188] In the fully mounted state of the contact system 10 shown in Figure 22, the foil contact section 85 of the second contact element 700 thus contacts a further conductor track 35, 40 of the conductor track arrangement 30 of the flexible conductor foil 20, such that, by means of the contact device 15 shown in Figure 22, two different conductor tracks 35, 40 of the conductor track arrangement 30 can be contacted.TE Connectivity Solutions GmbH AMP19310PC 28

[0189] The connection portion 90 of the second contact element 700 may, for example, be connected to a further component with an integral bond and electrically. In particular, to another cell connector.

[0190] The mounting method described in Figure 18 is substantially identical and is adapted for Figure 22 only to the effect that, in addition to the first contact element 55, the second contact element 700 is also inserted into the housing interior 165 and is oriented in a defined way along the displacement axis 95 corresponding to the desired raster position.TE Connectivity Solutions GmbH AMP19310PC
