Description

Technical Field

[0001] The present invention relates to a sealing device for electrical connection, a plug connector, and an electrical connection. Background Technology

[0002] Electrical connections used for transmitting electrical energy or signals are increasingly being used in environments with extreme temperatures, near moisture and / or liquids. To address these environmental effects, connectors must be designed in a way that reliably maintains transmission quality and can withstand the impact of the corresponding usage location or application area (e.g., in the automotive field).

[0003] Connectors used for this type of electrical connection are typically designed with or sealed to prevent liquids and / or dust from penetrating into the connector. Especially for modular connectors that integrate multiple contact systems within a common housing, it is sometimes necessary to seal each module individually. This individual sealing significantly increases the mating force required during assembly, which compromises the usability of the electrical connection.

[0004] Therefore, there is a need for a sealing device for electrical connections that has multiple seals, where the mating force is reduced, and which is easy to manufacture and provides a reliable seal. Summary of the Invention

[0005] The present invention addresses this problem by providing a sealing device for sealing electrical connections, wherein the electrical connection has multiple interfaces at which plugs and mating connectors of the electrical connection can mate with each other along a mating direction; wherein the sealing device includes: a first sealing region assigned to a first interface of the plurality of interfaces; a second sealing region assigned to a second interface of the plurality of interfaces; wherein the first sealing region and the second sealing region each have a plurality of sealing protrusions sequentially arranged in the mating direction; and wherein the sealing protrusions of the first sealing region are arranged to be offset from the sealing protrusions of the second sealing region in the mating direction.

[0006] This solution, with its offset arrangement featuring sealing protrusions, allows for better and more efficient distribution of force peaks during mating, thereby reducing the total mating force required during mating of the connector and the plug of the electrical connection. This facilitates a compact design by eliminating the need for larger levers, while also reducing material wear.

[0007] The invention can be further improved by the following constructions, which are advantageous in themselves and can be combined with each other in any way.

[0008] The terms plug and mating connector do not limit the corresponding components to convex embodiments or complementary concave embodiments. These terms are intended only to clearly distinguish between a part and a complementary part. A plug can be a male plug or a female plug; a mating connector can be designed accordingly to be complementary to it.

[0009] The first and / or second sealing portions may have openings, through openings, into which a plug and / or mating connector can be inserted. The mating connector can be received in the through opening, particularly in embodiments where the plug is a female plug. Alternatively, the through openings of the first and / or second sealing portions may respectively accommodate plugs configured as male plugs. The corresponding sealing portions may abut against the walls of the plug or interface, i.e., against the plug wall and / or interface wall.

[0010] The terms "first" and "second" are used specifically for conceptual distinction and can be used interchangeably as needed. A characteristic applicable to a component with the name "first" can also apply to a component with the name "second," and vice versa.

[0011] The sealing area may have a sealing area wall that surrounds the through opening, particularly in the direction of mating. The sealing area wall may rest against a plug wall or interface wall on one side. On the side of the sealing area wall opposite to the interface wall, a sealing protrusion may extend into the through opening in a direction transverse to the mating direction, or may protrude toward the through opening. Alternative embodiments may have a sealing protrusion pointing away from the through opening, particularly in a direction transverse to the mating direction. If the plug or interface is configured as a male plug, the corresponding sealing protrusion may protrude from the outside of the sealing area wall and from the outside of the plug wall or interface wall. This provides the advantage of easier access to the sealing device, allowing for more rapid maintenance or replacement of the corresponding sealing device and / or the corresponding sealing area.

[0012] In the mating direction, the sealing protrusions of the first sealing region and / or the sealing protrusions of the second sealing region may be spaced apart from each other. For example, the sealing protrusions of the first sealing region and / or the sealing protrusions of the second sealing region may be separated from each other by a recess, particularly in the mating direction. Therefore, the recess may be located between two sealing protrusions of the sealing region.

[0013] The sealing protrusions and recesses of the first sealing region and / or the sealing protrusions and recesses of the second sealing region can be made from a single component. Therefore, the first sealing region and / or the second sealing region can be integrally or monolithically constructed as a single piece. Another embodiment features an integrally constructed sealing device in which the sealing regions can be connected to each other, and thus the first sealing region can be connected to the second sealing region. The sealing device can, for example, be constructed as a sealing gasket with integrally connected sealing regions. This simplifies the manufacturing process because less assembly work is required. Fewer parts are needed, and furthermore, the integral sealing device and / or sealing region can be manufactured with high dimensional accuracy.

[0014] Embodiments of the sealing device may also have separate radial seals and / or separate and separate sealing sections. This provides the advantage of flexible adaptation to external conditions and separate, particularly modular, plug connectors and / or electrical connections.

[0015] Another embodiment may include sealing protrusions arranged sequentially in the mating direction in each sealing area, these sealing protrusions being unconnected to each other. This facilitates operation because each sealing protrusion can be inserted or removed individually, and the installation of the sealing device can be adapted to specific requirements.

[0016] In one embodiment, the sealing protrusions of the first sealing region and / or the sealing protrusions of the second sealing region may be equidistant from each other, particularly along the mating direction. This provides the advantages of simplicity and accelerated manufacturing, as fewer individual adjustments are required, especially when using standardized distances.

[0017] The sealing protrusion can be configured as a sealing lip. The corresponding sealing protrusion can have a maximum value that defines the point where the sealing protrusion protrudes furthest transversely to the mating direction. Therefore, in the transverse direction to the mating direction, the maximum value marks the highest point or apex of the corresponding sealing protrusion, which is furthest from the wall of the sealing area.

[0018] The sealing protrusion of the first sealing region can be located at the same height as the recess of the second sealing region in the mating direction. This provides the advantage of reduced mating force when, for example, the first mating connector is simultaneously inserted into the first sealing region and the second mating connector is inserted into the second sealing region along the mating direction. In particular, the corresponding mating connector can be inserted through the through opening of the corresponding sealing region.

[0019] The sealing protrusions in the first sealing region and / or the sealing protrusions in the second sealing region, as well as the recesses in the first sealing region and / or the recesses in the second sealing region, can be constructed identically. For example, each sealing protrusion in the first sealing region and / or each sealing protrusion in the second sealing region can have the same width in the mating direction. The width of the sealing protrusions in the first sealing region and / or the width of the sealing protrusions in the second sealing region can be the same along the insertion direction. The width can be measured from the inflection point to the inflection point along the mating direction.

[0020] The highest points or apexes of the sealing protrusions in the sealing region (e.g., the first sealing region) can be equidistant from each other in the mating direction. The apexes can lie on a straight line extending parallel to the mating direction. Similarly, each recess can have a minimum value located closest to the wall of the sealing region in a direction transverse to the mating direction, and this minimum value can also lie on a straight line parallel to the mating direction. Therefore, the minimum value marks the deepest point of the recess in the direction transverse to the mating direction.

[0021] In one configuration, the sealing protrusions and recesses can be combined into a sinusoidal curve along the mating direction. Specifically, the sealing region can be sinusoidally constructed on the sealing side. In this context, the sealing side is the side of the sealing region wall where the sealing protrusions project or penetrate through an opening.

[0022] In the mating direction, the distance between the first sealing protrusion of the first sealing region and the first end of the first sealing region can be greater than the distance between two sealing protrusions of the first sealing region arranged successively in the mating direction. The first end of the first sealing region can be the end of the sealing region closest to the first sealing protrusion in the mating direction. For example, the first end can directly face the mating connector in the mating direction. The first sealing protrusion can be the sealing protrusion of the corresponding sealing region that is first contacted by the mating connector during mating. Similarly, this configuration can be applied to the second sealing region.

[0023] Similarly, the distance between the apex of the first sealing protrusion in the first sealing region and the insertion opening of the designated interface in the mating direction can be greater than the distance between the apexes of two sealing protrusions arranged successively in the mating direction in the first sealing region; this can also be applied to the second sealing region.

[0024] The distance between the last sealing protrusion of the first sealing region and the second end of the first sealing region, and / or the distance between the last sealing protrusion of the second sealing region and the second end of the second sealing region, may be less than or equal to the distance between two sealing protrusions successively arranged in the mating direction of the first sealing region, and / or the distance between two sealing protrusions successively arranged in the mating direction of the second sealing region. The last sealing protrusion may be the sealing protrusion of the sealing region that is last contacted by the mating connector when the mating electrical connection is made. The second end of the corresponding sealing region may be the end furthest from the mating connector in the mating direction.

[0025] Similarly, for example, the distance between the apex of the first sealing protrusion of the first sealing region and the second end of the first sealing region can be less than or equal to the distance between the apexes of two sealing protrusions of the first sealing region arranged successively in the mating direction.

[0026] In an alternative embodiment, the distance between the first sealing protrusion of the first sealing region and the first end of the first sealing region may be less than or equal to the distance between two sealing protrusions of the first sealing region arranged successively in the mating direction. The distance between the last sealing protrusion of the first sealing region and the second end of the first sealing region may be greater than the distance between two sealing protrusions of the first sealing region arranged successively in the insertion direction; this may also be carried over to the second sealing region.

[0027] The first sealing region and the second sealing region can be arranged on a common plane perpendicular to the mating direction. The end of the sealing region facing the mating connector, i.e., the first end, can be located on the common plane perpendicular to the mating direction. In particular, the front edge of the sealing region can be located on the common plane perpendicular to the mating direction.

[0028] The ends of the corresponding sealing sections can be flush with the ends of the interfaces. In particular, the ends of the first sealing section can also be flush with the ends of the second sealing section; for example, the first end of the first sealing section can be flush with the first end of the second sealing section. The first ends of the first sealing section and the first ends of the second sealing section can be aligned in a row transverse to the mating direction and on a common plane. This achieves precise alignment, which ensures uniform force transmission and sealing.

[0029] The first and second sealing sections can be constructed identically. The first sealing section can be arranged next to the second sealing section by rotating 180 degrees about an axis that extends perpendicular to the mating direction in a direction transverse to the mating direction. Therefore, the sealing sections can be identical and can be inserted inverted relative to each other. This reduces the total number of parts to be manufactured and simplifies installation.

[0030] The first sealing region and / or the second sealing region may extend in a circumferential direction transverse to the mating direction. Specifically, the first sealing region and / or the second sealing region may extend in an annular shape in the circumferential direction. The shape may depend on the respective interface and be individually adapted. Therefore, the sealing regions may have the same profile and / or dimensions as the respective interfaces to which they are assigned.

[0031] In the case of electrical connections with three or more interfaces, the sealing device may have three or more sealing zones.

[0032] The third sealing section, or each odd-numbered sealing section, may correspond to the first sealing section. The fourth, or each even-numbered sealing section, may correspond to the second sealing section.

[0033] The arrangement or positioning of the sealing areas corresponding to the first sealing area and the arrangement of the sealing areas corresponding to the second sealing area are variable and can be adjusted individually on the common plane. It is not important whether the sealing area corresponding to the first sealing area is in an even or odd position, and / or whether the sealing area corresponding to the second sealing area is located next to the sealing area configured as the first sealing area.

[0034] Therefore, another identical sealing region corresponding to the first sealing region can be arranged next to the sealing region corresponding to the first sealing region. This will not impair the function of the sealing device, as long as the sealing device has at least one second sealing region having a sealing protrusion offset from the sealing protrusion of the first sealing region. Preferably, the sealing device may have an equal number of sealing regions having sealing protrusions at the height of the first sealing region and sealing regions having sealing protrusions at the height of the second sealing region.

[0035] The sealing device may have sealing areas arranged in a row, for example, in a direction transverse to the mating direction. The sealing device may have sealing areas arranged in a grid, for example, in a 2x2 grid or a 2x4 grid. The sealing areas may, in particular, be arranged in such a grid or row on a common plane.

[0036] The present invention also solves the problem of plug connectors having multiple interfaces and sealing devices as described above, wherein in the mating state, a first sealing region seals a first interface and a second sealing region seals a second interface.

[0037] A plug connector can have multiple plugs configured to connect with a mating connector. The number of plugs can correspond to the number of interfaces. An interface is the point where the plug and the mating connector make contact in the mated state.

[0038] Multiple plugs can have multiple plug openings or insertion openings, especially if the plug is constructed as a female. A sealing region can be provided for each insertion opening. The sealing region can extend circumferentially along the corresponding insertion opening. The plug connector openings and / or insertion openings can be openings of any polygonal shape.

[0039] The first and / or second sealing regions may be arranged or rested on the interface wall and / or the connector wall or plug wall in the circumferential direction, for example, on the inner side of the interface wall or plug wall. Alternatively, the corresponding sealing regions may be rested on the outer side of the interface wall or plug wall, for example, if it is a male plug.

[0040] The first sealing area and / or the second sealing area may have a sealing protrusion on the sealing side, which protrudes transversely to the mating direction away from the interface wall.

[0041] The apex of each sealing protrusion in the sealing region can be located further away from the interface wall than the minimum value of at least one recess in the sealing region.

[0042] The present invention further solves the problem of electrical connection having a plug connector as described above and at least one mating connector, wherein the mating connector may be part of a mating connector plug. The mating connector plug may consist of multiple mating connectors. The number of mating connectors may correspond to the number of plugs and / or interfaces. The sealing device as described above can be sealingly arranged between the plug and the mating connector in the mated state of the plug connector. In particular, the sealing device can be sealingly arranged between the plug and the mating connector in the mated state of the plug connector and the mating connector plug.

[0043] The sealing protrusions of the sealing device arranged on the plug connector can be supported on the inside or outside of the mating connector and / or the plug of the mating connector in the mating state. Attached Figure Description

[0054] Figure 1 A sealing device 100 with a sealing region 102 is shown. In this embodiment, a first sealing region 104 is arranged next to a second sealing region 106. The sealing region 102, particularly the cross-section 108 of the sealing region 102, can be configured as annular and, for example, formed as an ellipse or circle along the circumferential direction 110.

[0055] The sealing area 102 may have a through opening 112 that extends along a mating direction 114 that is transverse to the circumferential direction 110.

[0056] The sealing region 102 may have a plurality of sealing protrusions 116. The plurality of sealing protrusions 116 may protrude or extend along the circumferential direction 110 from the sealing region wall 118 surrounding the through opening 112. Figure 1 In the middle, among the plurality of sealing protrusions 116, the sealing protrusion 120 protrudes from the sealing area wall 118 toward the through opening 112, particularly toward the center 122 of the through opening 112. The side of the sealing protrusion 120 protruding from the sealing area wall 118 can be defined as the sealing side 124.

[0057] The sealing side 124 may also be the outer side 125 of the sealing area wall 118, wherein the sealing protrusion 120 of the plurality of sealing protrusions 116 protrudes away from the sealing area wall 118 and the through opening 112.

[0058] Along the mating direction 114, the sealing protrusions 120 among the multiple sealing protrusions 116 can be arranged sequentially.

[0059] The first sealing section 104 and the second sealing section 106 can be integrally constructed and connected to each other by a material section or material bridge 126. Another embodiment of the sealing device 100 provides sealing sections 102 that are separately constructed and can be installed separately from each other.

[0060] At least a portion of the outer side 125 of the first sealing region 104, such as the longitudinal side 128 of the first sealing region 104, may face at least a portion of the outer side 125 of the second sealing region 106, such as the longitudinal side 128 of the second sealing region 106.

[0061] Figure 2 An embodiment of a sealing device 100 having a first sealing region 104 and a second sealing region 106 is shown, the first sealing region 104 and the second sealing region 106 being arranged adjacent to each other along a direction 202 transverse to the mating direction 114. Also in this depiction, sealing protrusions 120 are arranged successively along the mating direction 114.

[0062] The sealing protrusion 120 can be configured as a sealing lip. Each sealing protrusion 120 can have a maximum value or vertex 204 that is furthest from the sealing region wall 118 along a direction 202 transverse to the mating direction 114.

[0063] The sealing protrusion 120 may have a width 206 along the mating direction 114. The width 206 of the sealing protrusion 120 may be greater than the distance 208 between the two sealing protrusions 120 of the sealing area 102.

[0064] Between the two sealing protrusions 120, the sealing area 102 may have a recess 210. The recess 210 may connect the two sealing protrusions 120 arranged successively along the mating direction 114. In one embodiment, the recess 210 may completely separate the two sealing protrusions 120 arranged successively.

[0065] The recess 210 may have a minimum value 212, which is the point of the recess 210 closest to the sealing area wall 118 in the direction 202 transverse to the mating direction 114. The minimum value 212 may be arranged on the minimum value line 214 parallel to the mating direction 114. Similarly, the maximum value point or vertex 204 may be arranged on the maximum value line 216 parallel to the mating direction 114.

[0066] Sealing areas 102, particularly the first sealing area 104 and the second sealing area 106, can be arranged side by side on a common plane 218. This common plane 218 can extend laterally or perpendicularly to the mating direction 114, for example, along a direction 202 laterally to the mating direction 114.

[0067] The distance 220 between the maximum values ​​204 of the two sealing protrusions 120 in the mating direction 114 can have the same value as the distance 222 between the minimum values ​​212 of the sealing area 102. The distance 224 between the first sealing protrusion 226 and the first end 228 of the sealing area 102 can be greater than the width 206 of the sealing protrusion and / or greater than the distance 208 between two successively arranged sealing protrusions 120, and / or greater than the distance 220 between the maximum values ​​204 of the two successively arranged sealing protrusions 120 along the mating direction 114.

[0068] Similarly, the distance 230 between the last sealing protrusion 232 and the second end 234 of the sealing area may be less than the width 206 of the sealing protrusion 120 and / or the distance 208 between the two sealing protrusions 120 and / or the distance 220 between the maximum value 204 of the two successively arranged sealing protrusions 120.

[0069] The recess 210 can be configured to face the sealing protrusion 120. The sealing protrusion 120 and the recess 210 can be configured together in a wavy (e.g., sinusoidal) manner along the mating direction 114.

[0070] The first sealing region 104 and the second sealing region 106 may have a height 236 along the mating direction 114, which has the same value.

[0071] Figure 3 An embodiment of a sealing device 100 for an electrical connection 300 is shown. The electrical connection 300 has a plug connector 302 having an interface 303 and a plug 305. The plug connector 302 may have a first interface 304 and a second interface 306, which may belong to a plurality of interfaces 303.

[0072] Interfaces 304 and 306 may each have an insertion opening 308, and the mating connector 310 of the mating connector plug 312 may be inserted into the insertion opening in the mating direction 114.

[0073] Sealing devices 100 can be arranged at corresponding interfaces 304, 306 of the plug connector 302. Each interface 304, 306 can be provided with sealing regions 104, 106. Similarly, each plug 305 can be provided with a corresponding sealing region 102. For example, a first sealing region 104 can be arranged or attached to the interface wall or plug wall 314 of the first interface 304.

[0074] The sealing section 102 can be arranged on the inner side 316 of the corresponding interface wall 314. The sealing protrusion 120 can protrude into the insertion opening 308 in a direction 202 transverse to the mating direction 114.

[0075] Alternative embodiments may have a sealing device 100 disposed on the outer side 318 of the interface wall or plug wall 314. The mating connector plug 312 may be accordingly configured as a female mating connector, plug connector 302, and in particular plug 305, into which it can be inserted.

[0076] The sealing device 100 may have multiple sealing protrusions 116, for example, each sealing region 102 may have three sealing protrusions 120. Figure 3 In the middle, the sealing side 124 is located on the inner side 316 of the plug wall 314.

[0077] The end 318 of the interfaces 304 and 306 can be flush with the ends 228 and 234 of the sealing area 102.

[0078] The sealing device 100 may have a first sealing region 104, which is arranged relative to the second sealing region 106 such that the distance 224a between the first sealing protrusions 120, 226 and the first end 228 of the first sealing region 104 is less than the distance 224b between the first sealing protrusion 120 and the first end 228 of the second sealing region 106.

[0079] The sealing protrusion 120a of the first sealing region 104 is preferably arranged offset relative to the sealing protrusion 120b of the second sealing region 106 along the mating direction 114. In another embodiment, the sealing protrusion 120a of the first sealing region 104 may be directly opposite the recess 210 of the second sealing region 106 in a direction 202 transverse to the mating direction 114. Therefore, along the direction 202 transverse to the mating direction 114, the apex 204 of the sealing protrusion 120a of the first sealing region 104 may be located on the same line as the minimum value 212 of the second sealing region 106.

[0080] Each of the plurality of sealing protrusions 116 in the first sealing region 104 can be positioned relative to a corresponding recess 210 in the second sealing region 106.

[0081] exist Figure 4 The illustration shows an embodiment with a plug connector 302 and a sealing device 100. In this depiction, the sealing device 100 has a total of four sealing sections. Other embodiments of the sealing device 100 may have any number of sealing sections 102. The number of sealing sections 102 is freely adaptable and modular depending on the corresponding plug connector 302 or electrical connection 300.

[0082] The sealing device 100 may have a plurality of sealing regions 102 configured as first sealing regions 104 and a plurality of sealing regions 102 configured as second sealing regions 106. For example, the sealing device 100 may have two sealing regions 102 having sealing protrusions 120 at the height of the first sealing regions 104, and two sealing regions 102 having sealing protrusions 120 at the height of the second sealing regions 106. The first sealing regions 104 may be arranged next to the second sealing regions 106 along a direction 202 transverse to the mating direction 114.

[0083] Two identical sealing sections 102, such as two sealing sections 102 having sealing protrusions 120 at the height of the second sealing section 106, may also be arranged along a direction 202 transverse to the insertion direction 114. Generally, the sealing device may have the same number of sealing sections 102 (which have sealing protrusions 120 at the height of the first sealing section 104) and sealing sections 102 (which have sealing protrusions 120 at the height of the second sealing section 106).

[0084] An alternative embodiment of the sealing device 100 may have a first sealing region 104 and a second sealing region 106 alternately along at least one direction 202 transverse to the mating direction 114, such that when viewed from the outside 402 of the plug connector 302, each odd-numbered position has a first sealing region 104 and each even-numbered position has a second sealing region 106.

[0085] The corresponding sealing area 102 can be arranged on the inner side 316 of the interface wall 314. The corresponding sealing area 102 can extend along the circumferential direction 110, which can extend around the mating direction 114.

[0086] The sealing area 102 can be separated from the plug connector wall or plug wall 404 extending along the mating direction 114 in a direction 202 transverse to the mating direction 114, which may at least partially correspond to the interface wall 314.

[0087] exist Figure 4 In this configuration, the end of the interface 318 is flush with the first end 228 of the sealing region 102. The ends, particularly the end of the interface 318 and the corresponding end 228 of the sealing region 102, may lie on a common plane 218 that extends perpendicular to the insertion direction 114.

[0088] The second sealing region 106 can be constructed in the same way as the first sealing region 104. During the installation of the sealing device 100, the second sealing region 106 can, for example, be rotated 180 degrees in a direction 202 transverse to the mating direction 114 and installed relative to the first sealing region 104. Therefore, the second end 234 of the first sealing region 104 can be the same as the first end of the second sealing region 106, and vice versa.

[0089] Figure 5 An alternative embodiment of a plug connector 302 with sealing device 100 is shown, constructed integrally or in one piece. The ends 228, 234 of the corresponding sealing portions 102 may be flush at at least one end in the integral construction, preferably flush at the end facing the mating connector 310 or the mating connector plug 312, and arranged on a common plane 218. The sealing portions 102 may not only be mounted at the same height in the mating direction 114, but may also be arranged adjacent to each other along the longitudinal side in a direction 202 transverse to the mating direction 114. At at least one end 228, 234, such as the end facing the mating connector 310, the corresponding sealing portions 102 may be connected to each other by material bridges 126 along at least one direction, such as a direction 202 transverse to the mating direction 114.

[0090] Figure 5 A depiction of the sealing region 102 attached to the inner side 316 of the corresponding interface wall 314 is also shown. In this embodiment, the sealing regions 102 are arranged alternately along a direction 202 transverse to the mating direction 114; therefore, a second sealing region 104 may exist between two sealing regions 102 having sealing protrusions 120 at the height of the first sealing region 104, the sealing protrusions 120 of which are offset relative to the sealing protrusions of the first sealing region 104 in the mating direction 114.

[0091] The end 502 of the sealing protrusion 120 can be constructed at an angle or in a rounded manner. The sealing protrusion 120 can take various forms to ensure a reliable seal.

[0092] Figure 6 A plug connector 302 with a sealing device 100 is shown, the sealing device 100 having a plurality of sealing portions 602. Sealing portions 102 of the plurality of sealing portions 602 may be located on a common plane 218. At least one end of each sealing portion 102 facing the mating connector 310 in the mating direction 114 may be located on the common plane 218. A recess 210 may be arranged here.

[0093] Multiple sealing sections 602 may be formed integrally or in one piece and connected to each other by means of a material bridge 126 between every two sealing sections 102. The material bridge 126 may be arranged on the longitudinal side 128 of the sealing section 102, for example, at the center of the longitudinal side 128. The material bridge 126 may have the same height or material thickness as the sealing section 102 connected to the material bridge 126 along the mating direction 114. The material bridge 126 may have a significantly smaller height or thickness, and for example, less than or equal to the width 206 of the sealing protrusion 120 in the mating direction 114.

[0094] For example, the four sealing sections 102 may be connected to each other along a direction 202 transverse to the mating direction 114. The sealing sections 102 do not necessarily have to be all connected to each other. Figure 6 In the middle, the four sealing sections 102 are connected to each other along the direction 202 transverse to the mating direction 114. The sealing sections 102 are not connected along the direction perpendicular to the mating direction 114 and the direction 202 transverse to the mating direction 114.

[0095] The sealing region 102 may terminate on or be disposed on the same plane 218 as the plurality of interfaces 307 of the plug connector 302. The corresponding sealing region 102 may be configured as an ellipse, such as... Figure 6 As shown. The sealing protrusion 120 can protrude toward the through opening 112 of the corresponding sealing area 102.

[0096] exist Figure 7 In this embodiment, the electrical connection 300 is shown in a mated state 702. The plug connector 302 has two interfaces 303, a first interface 304 and a second interface 306. Each of the interfaces 304 and 306 may have an insertion opening 308 in which a sealing device 100 or at least one sealing region 102 may be arranged. At least a portion of the sealing device 100 may be arranged on the interface wall 314, for example, on the inner side 316 of the interface wall 314.

[0097] The sealing protrusions 120 of each sealing section 102 may protrude toward the insertion opening 308 of the interface 303 or toward the through opening 112 of each sealing section 102 along a direction 202 transverse to the mating direction 114—particularly toward the center 704 of the sealing section or the through opening 112 of the sealing section 102.

[0098] The through opening 112 of the corresponding sealing section 102 and the insertion opening 308 of the sealing section 102 assigned to the interfaces 304 and 306 can be constructed concentrically with each other. The corresponding opening, the insertion opening 308 of the interfaces 304 and 306 and / or the through opening 112 of the sealing section 102 can be circular, elliptical, rectangular or polygonal. The corresponding sealing section 102 can be adapted to the corresponding shape or contour of the insertion opening 308 of the interfaces 304 and 306 and / or the through opening 112 of the sealing section 102.

[0099] The mating connector 310 of the mating connector plug 312 can be inserted into the insertion opening 308 of the interfaces 304 and 306 and into the through opening 112 of the corresponding sealing region 102. In this mating state 702, the sealing device 100 seals the electrical connection 300 to the outside. One side 706 of the mating connector 310, such as the outer side 708 of the mating connector 310, can be supported on at least one sealing protrusion 120 of the corresponding sealing region 102.

[0100] Interfaces 304, 306, or plug 305 can be configured as female plugs, into which the corresponding sealing portion 102 of the sealing device 100 is fitted. Alternatively, interfaces 304, 306, or plug 305 can be configured as male plugs, with the corresponding sealing portion 102 extending around the male plug, for example, around the mating direction 114. In this case, the sealing protrusion 120 protrudes away from the outer side 402 of the plug connector 302 or interface 303 in a direction 202 transverse to the mating direction 114. Thus, the mating connector plug 312 can have a female mating connector 310 that can receive the male plug 305.

[0101] Figure 8 Another embodiment of an electrical connection 300 with a plug connector 302 is shown, the plug connector 302 having a sealing device 100 disposed on the inner side 316 of a corresponding interface wall 314.

[0102] Electrical connection 300 is shown in a mating state 702. Plug connector 302 may have four interfaces 303. A first sealing region 104 may be assigned to or associated with the first interface 304. A second sealing region 106 may be assigned to the second interface 306. The reduction in mating force along the mating direction 114 is achieved by offsetting the sealing protrusion 120 in the mating direction 114. This requires less force to insert the mating connector 310 or mating connector plug 312 into or to connect the mating connector plug 312 to the plug connector 302.
