Description

Technical Field

[0001] This invention relates to the technical field of protective elements for improving electromagnetic compatibility. Background Technology

[0002] Electromagnetic compatibility (EMV) refers to the non-interference between electrical or electronic equipment and its environment.

[0003] Modern motorized vehicles are at least partially electrically powered. Therefore, in addition to high-performance electrochemical energy storage devices, motorized vehicles are equipped with converters and electric motors for driving or accelerating the vehicles. All components are interconnected via power cables.

[0004] A converter can be used to convert direct current (DC) supplied by an electrochemical energy storage device into alternating current (AC). A converter is also called an inverter.

[0005] Therefore, modern motorized vehicles include sources of strong electric, magnetic, or electromagnetic fields.

[0006] In addition, an increasing number of devices that communicate via electrical signals, magnetic signals, electromagnetic signals, or electromagnetic waves are being integrated into motor vehicles or used by vehicle occupants within motor vehicles.

[0007] Therefore, ensuring EMV (Electronic Vehicle Volume) is becoming an increasingly important challenge. This should be achieved with the lowest possible component weight, so that the weight of the mobile vehicle increases as little as possible or only slightly.

[0008] To shield sources of electromagnetic radiation, protective devices can be used to improve electromagnetic compatibility. A protective device may have at least two protective elements that wholly or partially enclose the internal space of the device. The protective device may be a housing, with the protective elements being components of the housing. The protective elements may be partition elements that separate the internal space relative to the surrounding external space.

[0009] The entire electromagnetic radiation source, or a portion or section of the electromagnetic radiation source, can be arranged within the internal space of the protective device. Alternatively, electromagnetically sensitive equipment, or portions or sections of such equipment, can be arranged within the internal space of the protective device to achieve shielding against electromagnetic radiation sources located outside the internal space.

[0010] Document WO 2024 / 231253 A2 describes a contact element used to establish electrical contact between a contact area of ​​a protective element and a device. It describes that the contact element can be disposed at a carrier, wherein the carrier can be deformable and / or elastic. The contact element can include or be made of a conductive material, wherein the conductive material can include aluminum. The contact element can extend from the protective element side of the carrier to the device side of the carrier. The carrier can include and / or be made of an elastic sealing material. The elastic sealing material can include natural or synthetic rubber, such as EPDM rubber, silicone rubber and / or fluororubber, polyurethane and / or ethylene-tetrafluoroethylene copolymer, or be composed of the like.

[0234] As has been discovered in connection with this invention, certain contact devices or EMV sealing devices are particularly well suited for connecting two protective elements, separating elements and / or components with high electromagnetic shielding.

[0235] For example, contact devices and / or EMV sealing devices can be arranged in the flange area of ​​protective elements, separating elements, and / or components.

[0236] Contact devices and / or EMV sealing devices can enable conductive connections of protective elements, separating elements and / or components with low resistance and / or low impedance, and can simultaneously achieve high compensation, especially compensation for unevenness to avoid openings in electromagnetic shielding.

The corresponding conductive material 128 is a planar material 130. It can be, for example, a planar aluminum material 132, or aluminum foil. The first surface area 136 and the second surface area 138 are spaced-apart surface segments 140 of the conductive material 128.

[0283] Figures 4 to 6 and Figures 9 to 12 The contact device 112 shown also has a base 116. The contact device 112 shown here has a plastic material 118.

[0284] Figures 4 to 6 and Figures 9 to 12 The contact device 112 shown has a plastic profile 148. The plastic profile may be, for example, a flexible plastic profile 150 and / or an elastomer profile 152.

[0285] Figure 4 , Figure 5 and Figure 6 The height of the section 144 shown can be, for example, about 10 mm. Figure 4 The width of the cross-section shown can be, for example, approximately 4 mm. Figure 5 The width of the cross-section shown can be approximately 7 mm, and Figure 6 The width of the cross section shown can be approximately 10 mm. The dimensions given may specifically relate to the uncompressed state of the substrate 116 and / or the plastic profile 148, in which the contact device is not arranged between the members 122.

[0286] Figure 8 A contact device 112 is shown. The contact device has a contact area 120. The contact area 120 is a first contact area 124.

[0288] The contact device 112 may have a first contact area 124 at one of the contact units 184 and a second contact area 126 at the other of the contact units 184.

[0289] The conductive material 128 may be formed of one or more materials of the contact unit 184, and the first contact area 124 and the second contact area 126 are connected by means of the conductive material. These contact units 184 are electrically contacted with each other in an intermediate contact area 216 such that the first contact area 124 and the second contact area 126 are connected by means of the conductive material 128. The intermediate contact area 216 may, for example, be a friction contact area 218.

[0290] Figure 8 The contact device 112 shown has a clamping mechanism 230. The clamping mechanism 230 is capable of generating a reaction force against a force that causes the two contact areas 124 and 126 to move toward each other.

[0291] Alternatively or additionally, the clamping mechanism 230 can enhance, ensure, and / or stabilize the electrical contact between contact units 184 in an intermediate contact area 216, such as a friction contact area 218. For example, this can be achieved by the clamping mechanism 230 pressing one contact unit 184 against another contact unit 184 in an intermediate contact area 216, such as a friction contact area 218.

[0292] Clamping mechanism 230 Figure 8The example shown includes a compression spring element 232, which can be used to generate a reaction force; and an intermediate contact promoting element 234, which can be used to enhance, ensure, and / or stabilize electrical contact in the intermediate contact area 216, such as the friction contact area 218. In the example shown, the compression spring element 232 and the intermediate contact promoting element 234 are different components of the contact device 112. However, the two functions of the two elements 232 and 234 can be alternatively achieved by a compression mechanism 230 consisting of only one component.

[0293] Figures 4 to 6 and Figure 8 The contact device 112 shown does not have a contact protrusion. However, it may be advantageous for the contact device 112 to have a contact protrusion 154.

[0294] The contact device 112 having the contact protrusion 154 is, for example, Figures 9 to 12 The contact device 112 shown.

[0295] Figures 9 to 12 The contact device 112 shown has a top surface region 156 and a bottom surface region 158.

[0297] The substrate 116 and the contact protrusion 154 are made of plastic material 118.

[0312] Figure 9 An example of a contact device 112 is shown, wherein a support protrusion 162 is arranged and / or configured at the contact device 112 such that the support protrusion 162 can support the contact lip 192 when the contact lip 192 bends, for example, in contact with member 122.

[0313] Figure 10 An example of a contact device 112 is shown, wherein a contact protrusion 154 extends from a base 116 through a segment 194 of the contact protrusion 154 spaced apart from the base 116, wherein the base 116 and the contact protrusion form a cavity 196.

[0314] Figure 10 An example of contact device 112 is shown, wherein a contact protrusion extends from a plastic profile section 172 of plastic profile 148 through a section 194 of contact protrusion 154 spaced apart from plastic profile section 172, wherein plastic profile section 172 and contact protrusion 154 form a cavity 196.

[0315] Figure 13 A simplified schematic diagram illustrates the protective element 110 used to improve electromagnetic compatibility. Figure 13 The protective element 110 shown may be, for example, Figure 1 One of the partition elements 104 shown schematically. It may be one of the components 122 of the housing 100 shown therein.

[0316] exist Figure 13 In this configuration, the observer's line of sight extends along the assembly direction 212, and the protective element 110 can be assembled along this assembly direction. Figure 13The protective element shown has a span 202 in a first direction 200. It has a span 206 in a second direction 204 orthogonal to the orientation of the first direction 200. An observer views the protective element 110 along an assembly direction 212, which is orthogonal to both the first and second directions. The protective element 110 has an attachment surface 208 and / or a contact surface 210 facing the observer viewing the protective element 110 along the assembly direction 212.

[0317] Optionally, the attachment surface 208 and / or the contact surface 210 may be located in a plane that intersects orthogonally with a straight line extending along the assembly direction.

[0318] Figure 14 and Figure 15 It shows Figure 13 The feasibility of the design scheme for the protective element 110 shown. For example, Figure 14 It shows the path taken along line XIV-XIV, passing through Figure 13 The cross-section of the edge region of the protective element 110 shown.

[0319] Figure 15 It shows the passage taken along line XV-XV, passing through Figure 13 The cross section of the edge region of the protective element 110 shown.

[0320] Figure 14 and Figure 15 Only partially shown cross sections are shown through a protective element 110 for improving electromagnetic compatibility, wherein the protective element 110 has a shielding layer 220 for protection against electric, magnetic or electromagnetic fields and a contact device 112 in electrical contact with the shielding layer 220.

[0321] Figure 14 The contact device 112 of the protective element 110 shown is based on Figure 12 The contact device.

[0322] Figure 15 The contact device 112 of the protective element 110 shown is similar to Figure 5 The contact device 112 shown. With Figure 5 The contact device 112 shown is different in that, Figure 15 In the contact device 112 shown, a conductive material, such as aluminum foil 134, is arranged such that the plastic material 118 of the substrate 116 is completely covered.

[0323] exist Figure 14 In the protective element 110 shown, the contact device 112 is arranged such that the contact device 112 tapers toward the contact area 120.

[0324] The contact device defines a surrounding contact profile 222 at the protective element 110 for establishing electrical contact. Figure 13 In the diagram, the contact profile 222 is represented by a dashed line. The contact profile 222 may be closed on all sides or may have one or more interruptions.

[0325] In the Figure 13 and Figure 14 When observed together, it becomes clear that the contact device 112 and the surrounding contact profile 222 have the following characteristics:

[0326] - The contact profile 222 extends in plane 224. This plane is in Figure 14 The plane is represented by a dot. Here, the plane is marked as a dotted line because the observer's line of sight extends in plane 224.

[0327] - In the direction 226 extending orthogonal to the plane 224, the contact device 112 gradually tapers toward the contact profile 222.

[0328] exist Figure 15 In the protective element 110 shown, the contact device 112 is oriented such that the contact device 112 tapers toward the contact area 120. Figure 15 In the example shown, the contact device 112 tapers toward the contact area 120 because the contact device 112 is not installed horizontally, but rather in a so-called edge-standing manner.

[0329] Still in Figure 15 In the protective element 110 shown, the contact device 112 defines a surrounding contact profile 222 at the protective element, as it is located in... Figure 13 As shown in the image.

[0330] Still in Figure 15 In the protective element 110 shown, the contact profile 222 extends in the plane 224. This plane... Figure 15 The middle part is represented by a dot.

[0331] In the direction 226 extending orthogonal to the plane 224, the contact device 112 gradually tapers toward the contact profile 222.

[0332] For example, such as Figure 15As shown, the contact profile 222 can be a contact profile 222 constructed by the corner region 174 of the contact device 112. The corner region 174 can be a corner region 174 extending along the main extension direction 142 of the contact device 112. The corner region 174 can be a rounded corner region 174. For example, the contact device 112 may not have a contact protrusion 154 or the corner region 174 may not be a corner region 174 of the contact protrusion 154. Advantageously, the corner region 174 can be a corner region 174 of the substrate 116 or the plastic profile 148. It may be advantageous for the contact device 112 to be skewed relative to a direction 226 extending orthogonally to one or both planes 224.

[0333] Advantageously, in the cross-section of the contact device 112 and / or the plastic profile 148, the corner region 174 protrudes along a direction 226 extending orthogonally to one or both planes 224. Alternatively or additionally, the corner region 174 in the cross-section 144 along the direction 226 extending orthogonally to one or both planes 224 can form an end of the contact device 112. This end can be, in particular, an end that can first contact the surface of the member 122 facing the protective element 110 when the protective element 110 is assembled at the member 122.

[0334] Figure 16 and Figure 17 A segment of the protection device 101 for improving electromagnetic compatibility is shown in the schematic diagram. The complete protection device is... Figure 1 The diagram is shown in a rough, simplified manner. The protective device 101 shown here is the housing 100.

[0335] exist Figure 16 and Figure 17 The protective device shown in the middle section has two protective elements 110. Figure 16 and Figure 17 In the two protective devices shown, the two protective elements 110 can each form, wholly or partially, the internal space 106 of the corresponding protective device 101.

[0336] The two protective elements 110 are electrically connected to each other via one of the contact devices 112 described herein. For example, from... Figure 16 and Figure 17 As can be seen, there is electrical contact with at least one shielding layer 220 of one of the two protective elements 110 via the contact device 112.

[0337] exist Figure 16 and Figure 17 The protective element 110, represented only by dashed lines, is shown in... Figure 16 The illustrated embodiment has an inclined surface 228. When Figure 16The protective element 110 shown in the lower middle section is directed towards... Figure 16 When the protective element 110 shown above moves, an electrical contact is established between the contact device 112 and the protective element 110 indicated by the dashed line above via the inclined surface 228 of the protective element 110 shown above.

[0338] exist Figure 16 and Figure 17 In the two embodiments shown, electrical contact is established via the contact area 120 described herein and / or via the surrounding contact contour 222 described herein, particularly with the protective element 110 indicated above by dashed lines.

[0339] For example Figure 2 Compared to the expensive contact device 112 (spring element 114) shown, for example, Figure 3 The contact device 112 shown (a substrate 116 made of foamed plastic material 118) forms a cost-effective alternative for generating electromagnetic shielding.

[0340] In order to evaluate the suitability of contact device 112 for electromagnetic shielding, its resistance in the installed state was studied as follows:

[0341] Different contact devices 112 (according to) Figure 2 Spring elements and according to Figure 3 A contact device (with a substrate made of foamed plastic material) is arranged between flat metal surfaces in a testing instrument at three different test temperatures: 22°C, 60°C, and 85°C. Accordingly, a first contact area 124 can abut against one of the two metal surfaces, and a second contact area 126 can abut against the other. The metal surfaces are moved towards each other and stopped at a desired distance (4 mm, 5 mm, 6 mm, or 7 mm), at which distance the contact device 112 is compressed to different degrees and makes electrical contact with the metal surfaces via the two contact areas 124 and 126. The change in resistance from one metal surface to another is then recorded periodically over a period of hundreds to thousands of hours.

[0342] The following observations were obtained.

[0343] In addition to Figure 2 Apart from the spring element 114, which has low contact resistance due to being a metal spring, the resistance of all the contact devices 112 studied with a substrate 116 made of foamed plastic material 118 increased significantly after temperature aging.

[0344] The reason for this observation is believed to be the indentation loss of the foamed core material used here. The indentation loss leads to a decrease in the surface pressure of the metal cladding.

[0345] Figure 7 , Figure 18 , Figure 19 and Figure 20 The results obtained for different contact devices 112 under similar conditions in the described test apparatus are shown. In these four figures, the obtained resistances (vertical axis, milliohms) are given for different line loads (horizontal axis, unit: Newtons per millimeter [N / mm]) set in the test apparatus.

[0346] exist Figure 7 In the middle, the triangle represents the use of... Figure 4 The measurement data were obtained from the contact device 112, which has a matrix 116 made of ethylene propylene diene monomer (EPDM) rubber. The test was conducted three times in total, using three contact devices with the same structure (first test: filled triangle; second test: unfilled triangle with thin edge; third test: unfilled triangle with thick edge).

[0347] exist Figure 7 In the middle, the circle represents the use of... Figure 5 The measurement data were obtained from the contact device 112, which has a matrix 116 made of ethylene propylene diene monomer (EPDM) rubber. The test was conducted a total of three times, for which three contact devices with the same structure were used (first test: filled circle; second test: unfilled circle with thin edge; third test: unfilled circle with thick edge).

[0348] exist Figure 7 In the middle, the square represents the use of according to Figure 6 The measurement data were obtained from the contact device 112, which has a matrix 116 made of ethylene propylene diene monomer (EPDM) rubber. The test was conducted a total of three times, for which three contact devices with the same structure were used (first test: filled square; second test: unfilled square with thin edge; third test: unfilled square with thick edge).

[0349] Incorporating its results Figure 7 In all tests, the matrix was partially covered with aluminum foil 134. The EPDM of the matrix 116 is an elastomer-solid material 166.

[0350] The goal is to achieve the lowest possible resistance, especially below 1 mOhm, which should be achievable under the lowest possible line load, i.e., as far below 2 N / mm as possible. For example, the resistance varying with line load should be so small that log(y) < -x, where x represents the line load in N / mm and y represents the measurable resistance in mOhm of the contact device spanning the metal surfaces from one surface to another.

[0351] Figure 7 Clearly shown, using from Figure 4 , Figure 5 and Figure 6 The contact device 112 can achieve this goal in some cases.

[0352] Not used under all tested line loads according to Figures 4 to 6 The test contact device 112 achieves the condition log(y) < -x. Furthermore, from... Figure 4 , Figure 5 and Figure 6 Contact devices 112 with cross-sectional areas of approximately 10mm×4mm, 10mm×7mm and 10mm×10mm require relatively more assembly space and materials.

[0353] Figure 18 The test instrument described is shown using the method according to Figure 4 , Figure 11 and Figure 12 The results of the investigation of contact device 112 (resistance under a given line load).

[0354] Figure 11 The contact device shown has a width of approximately 2.9 mm and a height of approximately 9.3 mm in the cross-section shown. Figure 12 The contact device shown has a width of approximately 2.6 mm and a height of approximately 7.9 mm in the cross-section shown.

[0355] and Figure 7 The same as in the middle, Figure 18 The triangle in the image also represents the use of... Figure 4 The measurement data is obtained by the contact device 112, which has a matrix 116 made of ethylene propylene diene monomer (EPDM) rubber.

[0356] exist Figure 18 In the middle, the circle represents the use of... Figure 11Measurement data were obtained from contact device 112 (2.9 mm wide, 9.3 mm high), which has a substrate 116 made of ethylene-acrylate rubber (AEM), wherein the elastomer material has a Shore A hardness of 60 as measured according to DIN ISO 7619-1. The substrate is covered with aluminum foil. The test was performed a total of three times, for which three contact devices with identical structures were used (first test: filled circle; second test: unfilled circle with thin edge; third test: unfilled circle with thick edge).

[0357] exist Figure 18 In the middle, the square represents the use of according to Figure 12 Measurement data were obtained from contact device 112 (2.6 mm wide, 7.9 mm high), which has a substrate 116 made of ethylene-acrylate rubber (AEM), wherein the elastomer material has a Shore A hardness of 60 as measured according to DIN ISO 7619-1. The substrate is covered with aluminum foil. The test was conducted three times in total, for which three contact devices with identical structures were used (first test: filled square; second test: unfilled square with thin edge; third test: unfilled square with thick edge).

[0358] from Figure 18 As can be seen from this, under similar line loads, according to Figure 11 and Figure 12 The resistance in the contact device is basically the same as that according to Figure 4 The resistance in the contact device is also lower or lower than according to Figure 4 The resistance in the contact device is low. This demonstrates that when using a specific contact device according to the invention with contact protrusions, the same low or even lower resistance can be achieved with minimal assembly space and material cost. Surprisingly, a particularly low resistance is achieved despite a significantly smaller width of the contact area located at the contact protrusions.

[0359] Figure 19 The resistance under a given line load is shown, which is used in the described test instrument according to... Figure 9 The contact device 112 is used to determine (the upright square).

[0360] Figure 19 The other results shown (triangles and circles) are based on Figure 3 Obtained from contact device 112. With Figure 3 The difference is that the contact device 112 has a silicone foam with an approximately rectangular cross-section as the substrate 116, the dimensions of which are 10mm × 15mm.

[0361] from Figure 19 As can be seen from this, for example, using according to Figure 9The contact device 112 according to the invention can also achieve very low resistance from one metal surface across the corresponding contact device to another metal surface under low line load. Figure 9 The contact device offers feasibility with a particularly small cross-section, i.e., with low material cost. In contrast, even with a rectangular cross-section of silicone foam, there are concerns about indentation loss and the resulting increase in resistance during temperature aging.

[0362] Figure 20 Similarly, the test apparatus described is shown under a given linear load, according to... Figure 8 The contact device 112 has a known resistance (square) and is used according to Figure 10 The resistor (vertical square) identified by contact device 112.

[0363] Still Figure 20 Other results represented by triangles and circles are similar to Figure 19 The results are consistent with other findings. These are especially relevant for comparative purposes. Figure 20 As shown in the image.

[0364] from Figure 20 As can be seen from this, for example, using according to Figure 8 and Figure 10 The contact device 112 according to the invention can also achieve very low resistance from one metal surface across the corresponding contact device to another metal surface under low line load. Figure 8 and Figure 10 The contact device also offers feasibility with minimal material costs.

[0365] according to Figure 19 and Figure 20 The contact device 112 can be manufactured in a particularly material-saving manner due to its structural form, such as due to the associated cavity and / or the profile installed therein.

[0366] exist Figure 21 , Figure 22 and Figure 23 The diagram shows segments of a protective device 101 for improving electromagnetic compatibility. Each protective device 101 has two protective elements 110. One of the two protective elements 110 is a protective element 110 according to the invention, which has a shielding layer 220 for protection against electric, magnetic, or electromagnetic fields. Figure 21 , Figure 22 and Figure 23 In the protection device 101 shown, two protection elements 110 are electrically connected to each other via a contact device 112 according to the invention.

[0367] Figure 21 , Figure 22 and Figure 23 The contact device 112 shown has a contact protrusion 154. Each contact protrusion 154 has a contact area 120. The contact areas 120 are first contact areas 124, and the contact device 112 also has second contact areas 126, wherein the first contact areas 124 and the second contact areas 126 are electrically connected. Figure 11 and Figure 12 The contact device 112 in the middle has similarity, therefore regarding Figure 21 , Figure 22 and Figure 23 Many consistent or corresponding features will not be described again, and Figure 21 , Figure 22 and Figure 23 Some of the figure labels in the illustrations have also been partially omitted.

[0368] The first contact area 124 and the second contact area 126 are connected by a conductive material 128. The conductive material 128 is a metallic material, for example, it may contain aluminum.

[0369] The conductive material 128 may be, for example, a metal foil, a metal grid, a metal mesh or a metal fabric, and in particular may be or have an aluminum foil 134, an aluminum grid, an aluminum mesh or an aluminum fabric.

[0370] For example, the conductive material 128 can be a planar material 130, especially a planar aluminum material 132, such as aluminum foil 134.

[0371] The corresponding contact device 112 has a first surface region 136 and a second surface region 138. The first contact area 124 is constructed in the first surface region 136, and the second contact area 126 is constructed in the second surface region 138.

[0372] The first surface region 136 and the second surface region 138 are spaced-apart surface segments 140 of the conductive material 128.

[0373] exist Figure 21 In the contact device 112 shown, the conductive material 128 extends almost entirely around the substrate 116 and almost entirely around the plastic profile 148 in a cross section 144 orthogonal to the main extension direction 142 of the contact device 112.

[0374] exist Figure 22 and Figure 23 In the contact device 112 shown, the conductive material 128 extends partially around the substrate 116 and partially around the plastic profile 148 in a cross section 144 orthogonal to the main extension direction 142 of the corresponding contact device 112.

[0375] Figure 21 , Figure 22 and Figure 23 The protective element 110 shown according to the invention has two barrier elements 238, one barrier element 238 and another barrier element 238. A shielding layer 220 extends at least sectionally between the two barrier elements 238. The shielding layer 220 may be disposed at the barrier elements 238. Optionally, the shielding layer 220 may form a layer composite 240 with the barrier elements 238, for example.

[0376] Figure 21 , Figure 22 and Figure 23 Each of the protective elements 110 shown has a sidewall 236 and an internal space 106. The internal space 106 is wholly or partially surrounded by the sidewall 236, which can only be roughly seen from the corresponding segments of the basin-shaped and / or trough-shaped protective elements 110 shown.

[0377] Therefore, the sidewalls 236 are formed wholly or partially by a barrier element 238.

[0378] Figure 21 , Figure 22 and Figure 23 The protective element 110 shown according to the invention each has a contact receiving area 242 in which a corresponding contact device 112 is arranged. In the three examples shown, the contact receiving area 242 each has a contact receiving recess 244 in which the corresponding contact device 112 is partially received. The contact receiving area 242 is limited by two barrier elements 238. A shielding layer 220 extends into the contact receiving area 242. The contact device 112 makes electrical contact with the shielding layer 220 in the contact receiving area 242.

[0379] Figure 21 , Figure 22 and Figure 23 The contact device 112 shown is an EMV sealing device 146. For example, they can create a fluid seal between two protective elements 110 or components 122 and achieve electromagnetic radiation shielding.

[0380] Figure 22 and Figure 23 The two contact devices 112 shown here have a contact section 246 and a sealing section 248 respectively in a section 144 orthogonal to the main extension direction 142 of the respective contact device 112. The contact section 246 has a contact protrusion 154. The contact protrusion 154 is a component contact protrusion 178 located in the contact section 246 at the component contact side 176 of the contact device 112. The sealing section 246 has a sealing protrusion 250. The sealing protrusion 250 is a sealing protrusion 250 located in the sealing section 248 at the component contact side 176 of the contact device 112.

[0381] The conductive material 128 extends from the first contact region 124 to the second contact region 126 in a cross section orthogonal to the main extension direction 142 of the corresponding contact device 112.

[0382] Figure 22 The contact protrusion 154 and sealing protrusion 250 in the contact device 112 shown are significantly larger than those in the other two devices. Figure 23 The contact protrusion 154 and sealing protrusion 250 in the contact device 112 shown.

[0383] from Figure 22 and Figure 23 As can be clearly seen, the contact device tapers toward the contact areas 120, 124, and 126. In particular, in the cross-sections shown, the contact protrusions are wider at the base of the respective contact protrusions than at the ends where the respective contact areas 124 or 126 are located.

[0384] Figure 22 The contact receiving area 242 shown has a sealing compartment 252 and a contact compartment 254. The second contact area 126 is in electrical contact with the shielding layer 220 in the contact compartment 254. The sealing section 246 has two opposing sealing protrusions 250, one of which extends into the sealing compartment 252.

[0385] An intermediate support section 258 extends into the contact device receiving area 242, separating the sealing compartment 252 from the contact compartment 254. An intermediate section 260 of the contact device 112 is located at the intermediate support section 258.

[0386] Figure 21 The protective element 110 shown according to the invention has a sealing element receiving area 264 in addition to the contact device receiving area 242, in which a sealing element 262 is arranged. The sealing element receiving area 264 has a sealing element receiving recess 266 in which the sealing element 262 can be received completely or partially. The sealing element receiving area 264 extends substantially parallel to the contact device receiving area 242.
