Description

Technical Field

[0001] The invention relates to a device for plug-in connection of electrical connections via a housing, in particular for a device for driving a compressor, such as an electric motor, which is used in particular for compressing a vaporous fluid, such as a refrigerant. The device has at least one plug-in connection with at least one plug-in connector for transmitting electrical energy and a mounting element for accommodating the plug-in connector. The mounting element can be fixed to the housing.

[0002] The invention further relates to a device for driving a compressor, in particular an electric motor, having a device for pluggably connecting an electrical connection, and to a method for mounting the device on a device for driving a compressor. The compressor can be used in a refrigerant circuit of an air conditioning system of a motor vehicle. Background Art

[0003] Compressors known from the prior art for mobile applications, in particular compressors for motor vehicle air conditioning systems and for conveying refrigerant via a refrigerant circuit, also referred to as refrigerant compressors, are usually manufactured as piston compressors with variable displacement or as refrigerant-independent scroll compressors, wherein the compressor is driven via a pulley or is driven electrically.

[0004] The electrically driven compressor has, in addition to an electric motor for driving a suitable compression mechanism, an inverter for driving the electric motor. The inverter is used to convert the direct current from the vehicle battery into a three-phase current, which is supplied to the electric motor via electrical connections.

[0005] The inverter has a plug-in connector for a plug-in connector for electrically connecting to a connector of the electric motor made as a pin, which in turn is electrically connected to a connecting wire of the conductor of the coil of the stator. The connector of the electric motor is made in a connector housing, which is arranged on the end face of the stator aligned in the axial direction of the stator.

[0006] The plug-in connector, which is arranged on the inverter or on the printed circuit board of the switchgear of the compressor and outside the housing of the compressor and is manufactured as a pin, is inserted into the connection terminals located in one of the connector housings during assembly of the compressor and each contacts the end piece connected to the appropriate wires, in particular the connecting wires of the wires. The plug-in connector inserted through the housing into the inverter arranged outside the housing must be sealed.

[0007] Conventionally, electrically driven compressors are manufactured with one plug-in connector each for the connection for transmitting electrical energy and communication signals in the low voltage region and one plug-in connector each for the connection for transmitting electrical energy in the high voltage region, the plug-in connectors being connected to the housing by means of a plurality of threaded connections and having a sealing element or several sealing elements. Thus, the two plug-in connectors to be mounted independently and the power supply and the plug-in connector ensuring communication are assembled by means of a plurality of screws and sealing elements, in particular two axial seals and two radial seals.

[0008] A large number of separate sealing elements and threaded connections mounted on the compressor housing from the outside, as well as the arrangement and configuration of the sealing elements and threaded connections, result in a high risk of contamination, which increases manufacturing costs and assembly time. In addition, the threaded connections require a minimum installation space on the housing to enable the screws to be inserted into the housing from the outside.

[0009] DE 10 2015 119 131 A1 describes a plug-in connector arrangement having a first electrical plug-in connector and a second electrical plug-in connector. The plug-in connectors each have a housing with an input and an output. At least one of the housings encloses an interior space in which a bus is arranged between the input and the output. The housings of the two plug-in connectors are connected to one another as a common plastic injection-molded component.

[0010] Furthermore, the plug-in connectors known from the prior art, which have a large number of components and therefore a large installation space, require a long assembly time, since, among other things, the possible installation space in the housing of the compressor and therefore also the installation space for the electrical plug-in connector is very small. Furthermore, plug-in connectors manufactured from a plurality of components result in high material costs, manufacturing costs and storage costs. Summary of the invention

[0075] Figure 1 A cross-sectional view of an electrically driven compressor 1 is shown, which has an electric motor 3 arranged in a housing 2 as a device for driving a compression mechanism 4. The electric motor 3 is supplied with electrical energy via a switching device 5.

[0076] The electric motor 3 has a stator 6 having a substantially hollow cylindrical stator core and a coil wound on the stator core, and a rotor 7 arranged inside the stator 6. The rotor 7 is set to perform a rotational motion when electric energy is supplied to the coil of the stator 6 via a connecting device. The connecting device 8 is manufactured on the end surface of the stator 6 and has a plurality of electrical connectors.

[0077] On the end face of the stator 6, which is provided with the connection device 8, a support element 9 is arranged, which is used to hold a connection terminal connected to a part of the electrical connection between the coil of the electric motor 3 and the switching device 5. The connection terminal is made with an electrically conductive, pin-shaped plug-in connector, which connects the connecting wire of the coil to the element of the switching device 5 so that an electrical connection is established.

[0078] The rotor 7 is coaxially arranged inside the stator 6 so that the rotor 7 can rotate about the rotation axis. The drive shaft 10 can be manufactured integrally with the rotor 7 or as a separate element.

[0079] The electric motor 3 and the compression mechanism 4 of a scroll compressor manufactured as a fixed scroll and a movable scroll are arranged in a volume enclosed by a housing 2, wherein the housing 2 is manufactured from a first housing element for accommodating the electric motor 3 and a second housing element for accommodating the compression mechanism 4, and is preferably manufactured from metal, in particular aluminum.

[0080] The movable scroll of the compression mechanism 4, in which the vaporous fluid, in particular the refrigerant, is compressed, is driven by a drive shaft 10 connected to the rotor 7 of the electric motor 3. According to an embodiment not shown here, the compression mechanism can also be manufactured with a wobble plate.

[0081] The switch device 5 for controlling and regulating the operation of the electric motor 3 comprises a circuit board 12 with different switching elements 11 and a bushing. Different control circuits and components supplied with electrical energy from an external power source via power lines are mounted and electrically connected on the printed circuit board 12. The bushing is used in particular to accommodate a plug-in connector as an electrical connection between the plug-in connector and the printed circuit board 12.

[0082] Figure 2 A device 20 ′ for plug-in connection of an inverter of an electric motor as a device for driving a compressor of a vaporous fluid according to the prior art is shown in a side view, the plug-in connectors 21 ′, 22 ′ being manufactured separately and therefore separated from one another. Figure 3a and Figure 3b The top view, side view and perspective view show Figure 2 A first plug-in connector 21 ′ of the device 20 ′ for plug-in connection, and Figure 4a and Figure 4b Also shown in top view, side view and perspective view Figure 2 A second plug-in connector 22 ′ of the device 20 ′ for making a plug-in connection.

[0083] The device 20 ′ for plug-in connection of electrical connectors of an electric motor is produced with a first plug-in connector 21 ′ for connection for transmission of electrical energy in the low-voltage region and a second plug-in connector 22 ′ for connection for transmission of electrical energy in the high-voltage region.

[0084] Each plug-in connector 21', 22' has a mounting element 23a', 23b' for accommodating a plug-in connector 24, 25, wherein the first plug-in connector 21' is provided with a first mounting element 23a' for accommodating a first plug-in connector 24, which is used for transmitting electrical energy in the low-voltage region, and the second plug-in connector 22' is provided with a second mounting element 23b' for accommodating a second plug-in connector 25, which is used for transmitting electrical energy in the high-voltage region. The plug-in connectors 24, 25 are each inserted into the mounting elements 23a', 23b' inside the feedthroughs 26, 27, and the plug-in connectors 24, 25 are arranged so that they themselves are inserted through the mounting elements 23a', 23b'.

[0085] Furthermore, each mounting element 23a', 23b' of the plug-in connector 21', 22' is produced with a first sealing element 28a', 28b' acting in the radial direction and a second sealing element 28c', 28d' acting in the axial direction.

[0086] The mounting elements 23a', 23b' are each connected to the housing by four fastening elements, such as screws, wherein each screw is arranged such that each screw is inserted through a through opening 29' formed in the mounting elements 23a', 23b'.

[0087] Therefore, the device 20' has two plug-in connectors 21', 22', which are to be installed separately and are manufactured to have at least eight fastening elements, in particular screws, and four sealing elements 28a', 28b', 28c', 28d' in their entirety and thus have multiple components, the four sealing elements being specifically two first sealing elements 28a', 28b' acting in the radial direction and two second sealing elements 28c', 28d' acting in the axial direction.

[0088] The description of the radial direction and the axial direction each relates to the alignment of the plug-in connectors 24, 25, which are aligned substantially parallel to one another in the longitudinal direction, wherein the longitudinal direction of the plug-in connectors 24, 25 also corresponds to the axial direction of the plug-in connectors 21 ', 22'. The radial direction is aligned orthogonally to the longitudinal direction of the plug-in connectors 24, 25 and thus to the axial direction of the plug-in connectors 21 ', 22'.

[0089] In addition, an interlocking connector 30' manufactured as an electrical interlocking component can be manufactured between the first plug-in connector 21' and the second plug-in connector 22' for controlling the transmission of electrical energy in the low voltage area and the high voltage area. The interlocking connector 30' has at least two conductive connection cables 31', which are each connected to the plug-in connectors 21', 22' at their ends via separate connectors in a manner that establishes a conductive connection.

[0090] The interlock connection 30' as a supply line connection is particularly useful for shutting down the high voltage area as soon as the electrical connection in the high voltage area is interrupted in an undesired manner. By early interruption of the current circuit, the interlock connection 30' thus performs a safety-related function of the device 20'.

[0091] After the plug-in connectors 21', 22' are assembled, the connecting cables 31' of the interlocking connector 30' are freely routed and electrically connected to the plug-in connectors 21', 22' at their ends via cable rods. In addition, the connecting cables 31' are fixed to the housing and / or printed circuit board by a fixing agent, in particular an adhesive.

[0092] Therefore, the device 20 ′ having the plug-in connectors 21 ′, 22 ′ and a large number of components having a complex structure requires not only a large installation space but also a long assembly time.

[0093] Figure 5a to Figure 5e A device 20 for plug-in connection of electrical connectors of an inverter of an electric motor according to the invention is shown in a perspective view. Figures 6a to 6d The diagram shows the Figure 5a , Figure 5c and Figure 5e A device 20 for plug-in connection of an electrical connector, and Figure 7a and Figure 7b The side cross-section shows the sealing element 28 from Figures 6a to 6d Detailed view of device 20. Figures 8a to 8f In accordance with Figure 8a In the stereogram and according to Figure 8b to Figure 8f The three-dimensional detailed view of the compressor housing 2 shows the Figures 6a to 6d A device 20 for plug-in connection of an electrical connector, and Figures 9a to 9e The compressor from FIG. 1 is shown in different side views and in a top view in a state of being mounted on the housing 2 of the compressor. Figures 6a to 6d Device 20.

[0094] The device 20 is manufactured as an integral component, whereby a first plug-in connector 21 for transmitting electrical energy in the low voltage region and a second plug-in connector 22, 22a for transmitting electrical energy in the high voltage region are combined in a common mounting element 23, wherein the plug-in connector 21 and the second plug-in connector 22, 22a have a common mounting element 23 for accommodating a first plug-in connector 24 and a second plug-in connector 25. The plug-in connectors 21, 22, 22a can be manufactured with different contours protruding beyond the mounting element 23, in particular on the side that faces outwards when mounted on the housing of the compressor. The difference is achieved by Figure 5a and Figure 5b This becomes apparent by comparison with the profile of the second plug-in connector 22, 22a shown in FIG. Figure 5a The outer wall of the plug-in connector 22 has a substantially rectangular cross section with continuously rounded corners and with the same radius in the plane spanned by the direction y and the direction z, but according to Figure 5b The form of the outer wall of the plug-in connector 22a is circular in a plane spanned by the direction y and the direction z. The walls of the plug-in connectors 21, 22, 22a can therefore be manufactured differently, in particular with reference to suitable cross-sections. Figure 5a The device 20 of the second plug-in connector 22 is provided.

[0095] The plug-in connectors 24, 25, each in the form of a straight pin, are each inserted into the mounting element 23 inside a through-hole 26, 27 and pass through the mounting element 23, wherein the respective plug-in connector 24, 25 inside the mounting element 23 of the device 20 is completely enclosed by the through-hole 26, 27 and is therefore arranged such that the plug-in connector is hermetically sealed relative to the mounting element 23. Each through-hole 26, 27 constitutes a component or region of the mounting element 23, wherein the mounting element 23 with the through-hole 26, 27 is manufactured as a coherent unit and a one-piece component, in particular a one-piece injection-molded element. The one-piece form is achieved during the forming process.

[0096] The mounting element 23 of the plug-in connector 21, 22 is manufactured with a sealing element 28, which acts both in the radial direction and in the axial direction. Figure 8d As shown, in addition to the plug-in connectors 24 , 25 which are arranged within the lead-throughs 26 , 27 and are inserted toward the outside through the housing 2 into the inverter or the printed circuit board 12 , the mounting element 23 itself is also sealed relative to the housing 2 .

[0097] The sealing element 28, which is preferably made of a hard body, has a first region 28-1 acting in the radial direction and a second region 28-2 acting in the axial direction, which in particular Figure 7b , in which the sealing element 28 that completely encloses the mounting element 23 is arranged through its first area 28-1 so that the sealing element 28 encloses the mounting element 23 in the circumferential direction, and is arranged through its second area 28-2 so that the sealing element 28 contacts the mounting element 23 in the axial direction.

[0098] Especially Figure 7b , the device 20 has a spring element 36, which faces the housing 2 in the installed state. The spring element 36, which is made of metal and is electrically connected to the second plug-in connector 25 of the second plug-in connector 22 for transmitting electrical energy in the high voltage area, is elastically deformed during the installation process while in contact with the housing 2. The second plug-in connector 25 of the second plug-in connector 22 is electrically connected to the housing 2 via the spring element 36, which improves the shielding of the second plug-in connector 22 in the high voltage area and the printed circuit board 12 relative to the first plug-in connector 21 in the low voltage area.

[0099] The inner surface of the mounting element 23, which is aligned towards the volume enclosed by the housing 2 when the device 20 is mounted on the housing 2, has an extension 32 protruding into this volume. The extension 32 is made on the wall of the mounting element 23, is arranged on a plane spanning the direction y and the direction z, and is aligned in the x direction substantially orthogonal to the wall.

[0100] The extension 32 has the form of a cylinder, in particular a hollow cylinder, with an opening 29 for accommodating a mounting sleeve 33 or a fastening element 35, the fastening element 35 being used to fix the mounting element 23 on the housing 2, and connected on its first end face to the wall of the mounting element 23. The extension 32 and the mounting element 23 are manufactured as a coherent unit and a one-piece component, in particular a one-piece injection-molded component. The opening 29 located inside the extension 32 is configured as a blind hole opening on the free second end face of the extension 32, which is manufactured to be located distally with respect to the first end face and facing the volume enclosed by the housing 2.

[0101] The mounting sleeve 33, which is also substantially manufactured in the form of a hollow cylinder, has an outer diameter which corresponds to the inner diameter of the opening 29. The extension 32 in the form of a cylinder and the mounting sleeve 33 are aligned coaxially with each other and are preferably in line with the end face in the region of the free second end face of the extension 32. The mounting sleeve 33 is incorporated into the extension 32 in a non-movable manner, in particular in a non-movable manner in the axial direction and therefore in the x-direction.

[0102] The mounting element 23 and a mounting sleeve 33 made of metal are connected to one another in a form-fitting manner, wherein the mounting sleeve 33 is embedded in the region of the extension 32 during injection molding of the mounting element 23 .

[0103] The inner lateral surface of the mounting sleeve 33 has an internal thread, which corresponds to the external thread of the fastening element 35, especially the external thread of the fastening element 35 made as a screw. The mounting sleeve 33, the extension 32 of the mounting element 23 and the fastening element 35 are configured as a threaded connection for fixing the mounting element 23 on the housing 2.

[0104] Figure 7c A mounting sleeve 33 for receiving a fastening element 35 is shown in a detailed view, the mounting sleeve 33 having a protruding end 33a and an axial anti-rotation device 33b.

[0105] The protruding end 33a is manufactured as a hollow cylindrical ring arranged on the outer lateral surface of the mounting sleeve 33, preferably centrally arranged between the end faces, and has a groove extending in the axial direction, wherein the outer diameter of the hollow cylindrical protruding end 33a is larger than the outer diameter of the mounting sleeve 33 in the remaining area, so that the protruding end 33a protrudes beyond the outer lateral surface of the mounting sleeve 33 along its entire circumference, and the outer lateral surface of the mounting sleeve 33 together with the protruding end 33a corresponds to the inner surface of the opening 29. The protruding end 33a has a significantly smaller extension in the axial direction than the mounting sleeve 33, so that the mounting sleeve 33 is prevented from moving in the axial direction in the opening 29.

[0106] The protruding end 33a of the hollow cylindrical shape is open over its entire circumference. A groove with a constant width is formed in the axial direction between the end faces of the protruding end 33a that face each other in the circumferential direction. Since the groove has a substantially rectangular cross section and extends through the protruding end 33a in the axial direction, the groove located inside the protruding end 33a is configured as an anti-rotation device 33b of the mounting sleeve 33 in the circumferential direction inside the opening 29 of the mounting element 23. According to an alternative embodiment not shown here, the anti-rotation device can also be made of at least two grooves distributed on the circumference or different types of form-fitting connections.

[0107] The device 20 according to the invention thus has a mounting element 23 enclosing two plug-in connectors 21, 22, which is manufactured with only one fastening element 35, in particular a screw, and one sealing element 28, in particular a sealing element 28 acting both in the radial direction and in the axial direction, and thus has a minimum number of components. The fastening element 35 is inserted from the interior of the housing 2 through the housing 2 into the mounting sleeve 33, so that the mounting element 23 is screwed onto the housing 2 from the inside.

[0108] During assembly, the device 20, which combines a first plug-in connector 21 for transmitting electrical energy and communication signals in the low-voltage region and a second plug-in connector 22 for transmitting electrical energy in the high-voltage region in a common mounting element 23, is inserted forwardly into the housing 2 in a movement direction 38 via the plug-in connectors 24, 25 aligned in the axial direction x, wherein the device 20 is inserted forwardly through a through opening 37 formed in the housing 2 via the sealing element 28 and the plug-in connectors 24, 25, as shown in detail. Figure 8d and Figure 8e The printed circuit board 12 will be equipped with bushings made to accommodate the insertion slots 39 of the plug-in connectors 24 , 25 .

[0109] During assembly of the device 20, each plug-in connector 24, 25 is inserted into an insertion slot 39 on the printed circuit board 12 via its free end arranged at the distal end relative to the mounting element 23 in the direction of movement 38, thereby establishing an electrical connection between the plug-in connector 24, 25 and the printed circuit board 12 or with components arranged on the printed circuit board 12.

[0110] In order to accommodate the plug-in connectors 24, 25, each insertion groove 39 is manufactured with a hollow cylindrical wall extending in the axial direction or movement direction 38 and protruding beyond the printed circuit board 12. Therefore, the wall of each insertion groove 39 is manufactured with an end face which is aligned with the mounting element 23 in the axial direction and is used to mount the plug-in connectors 24, 25.

[0111] In particular, according to Figure 5d In the embodiment of the device 20 of the embodiment of the invention, the interlocking connector 30 for controlling the transmission of electrical energy in the low voltage area and the high voltage area, which has a bus bar and is manufactured as an electrical interlocking part, can be located between the first plug-in connector 21 and the second plug-in connector 22. In the installed state, the bus bars arranged in pairs are arranged inside the mounting element 23, wherein the ends of the bus bars are configured so as to establish electrical contact with the corresponding plug-in connectors 24, 25. The bus bars of the interlocking connector 30 can preferably be manufactured as stamped and formed sheets.

[0112] The mounting element 23 can have a recess on one side, which corresponds to the form of the busbar, which is aligned with the plug-in connectors 24, 25 and thus enters the volume enclosed by the housing 2. Thus, the individual busbars of the interlocking connector 30 can be incorporated into the recess made in the mounting element 23. The busbars can be inserted into the recess of the mounting element 23 and fixed therein.

[0113] As the bus is inserted into the recess of the mounting element 23, in particular inserted into the desired position by snapping, the bus can simultaneously make electrical contact with the corresponding plug-in connectors 24, 25, so that a conductive connection is established between the corresponding plug-in connectors 24, 25, and the plug-in connectors 21, 22 are connected via the conductive connection.

[0114] The bus of interlocking connections 30 can be pre-assembled in the mounting element 23. Subsequently, the device 20 can be brought into the housing 2 of the compressor.

[0115] Especially Figure 5d As shown, the first plug-in connector 24 of the first plug-in connector 21 is completely enclosed in the axial direction by the stabilizing device 34 starting from the inner surface of the mounting element 23. The stabilizing device 34, which extends in the x direction and is manufactured in the form of a hollow cylinder, has a substantially rectangular cross section. The stabilizing device 34 is connected to the mounting element 23 on its first end face and is open on the end face aligned with the distal end of the first end face. The stabilizing device 34 has guide elements 34a at the corners of the substantially rectangular cross section that are arranged diagonally relative to each other, and the guide elements 34a are manufactured as straight pins and protrude beyond the open second end face of the stabilizing device 34.

[0116] In the device 20, Figure 8f In the assembled state as shown in FIG. 1 , the second end face of the stabilizing device 34 contacts the printed circuit board 12. The guide elements 34a protruding beyond the stabilizing device 34 on the second end face are each inserted through an opening located in the printed circuit board 12.

[0117] In accordance with Figure 8e When assembling the device 20 , the stabilizing device 34 and in particular the guide element 34 a serves to facilitate the insertion of the second plug-in connector 25 with the free end arranged distally relative to the mounting element 23 into the socket 39 on the printed circuit board 12 .

[0118] Fig.10a and Fig.10b A detailed view of the device 20 for plug-in connection of electrical connectors in a mounted state on the housing 2 of the compressor is shown in a lateral cross-sectional view. Fig.11 a to Fig.11 c shows a sealing element 28 of a device 20 for connecting electrical connectors by means of a plug-in connection in a perspective view, a top view and a side view.

[0119] In the assembled state of the device 20, the mounting element 23 is arranged such that it completely closes the through-opening 37 of the housing 2. The through-opening 26 of the first plug-in connector 24 and the through-opening 27 of the second plug-in connector 25 protrude into the volume enclosed by the housing 2.

[0120] The free end face of the extension 32 of the mounting element 23 is in contact with the housing 2, preferably over the entire area. The housing 2 has a through-opening 40 for inserting a fastening element 35 extending in the x-direction in a bearing area for the extension 32, the bearing area being arranged at a distance in the x-direction from the level of the through-opening 37. The bearing area is connected to a wall of the housing 2, which encloses the through-opening 37 over its entire circumference, in particular by a mesh-like connecting element.

[0121] The fastening element 35 is screwed from the interior of the housing 2 through the through opening 40 into the mounting sleeve 33, which is arranged in the extension 32 of the mounting element 23, so that the mounting element 23 is connected to the housing 2, in particular screwed to the housing 2. An anti-rotation element 41 is arranged between the fastening element 35 and the housing 2, which is made as a circlip and prevents the fastening element 35 from detaching.

[0122] Especially Fig.10b As shown, when the device 20 is assembled, the first region 28-1 of the sealing element 28 contacts the compressor housing 2 in the radial direction between the lateral surface of the wall of the housing 2 inside the through opening 37, which lateral surface encloses the through opening 37 and is also called the radial sealing surface of the housing 2, and the mounting element 23, while the second region 28-2 of the sealing element 28 is arranged in the axial direction or x-direction and therefore in the movement direction 38 between the mounting element 23 and the end face of the wall of the housing 2, which encloses the through opening 37 and is also called the axial sealing surface of the housing 2, in such a way that its entire circumference surrounds the through opening 37.

[0123] The first area 28-1 of the sealing element 28, which acts in the radial direction and is made substantially in the shape of a hollow cylinder, has an inner lateral surface in contact with the mounting element 23 and an extension made as a sealing lip 28-1a on an outer lateral surface, which is elastically deformed during mounting of the device 20 on the housing 2 of the compressor so as to come into contact with the radial sealing surface of the housing 2. The sealing element 28 is preferably made with three or four closed sealing lips 28-1a extending in the circumferential direction.

[0124] During the installation of the device 20 on the housing 2 of the compressor, the second region 28-2 of the sealing element 28 acting in the axial direction is elastically deformed in the radially outward direction between the chamfer formed on the mounting element 23 and the axial sealing surface of the housing 2. In addition, the second region 28-2 of the sealing element 28 manufactured as a disk has a convex closed thickening portion 28-2a on both sides in the axial direction, and the thickening portion 28-2a extends along the entire circumference and has an equal diameter and an equal axis of symmetry, so that the thickening portions 28-2a are arranged opposite to each other, wherein a first thickening portion 28-2a of the sealing element 28 is in contact with the mounting element 23, and a second thickening portion 28-2a of the sealing element 28 is in contact with the axial sealing surface of the housing 2.

[0125] The elastic deformation of the second area 28-2 of the sealing element 28 on the chamfer formed in the area of ​​the mounting element 23 and in the area of ​​the thickened portion 28-2a, and the elastic deformation of the sealing lip 28-1a of the first area 28-1 of the sealing element 28 are both intended to further increase the sealing performance in the axial and radial directions.

[0126] Due to the fact that the device 20 is manufactured with the sealing element 28 , the housing 2 is hermetically sealed.
