Description

Technical Field

[0001] The present invention relates to an installation unit for supporting a carrier element disposed on a vehicle body, the installation unit comprising a housing having a first housing section supported on a first outer side of a receiving area of ​​the carrier element and a second housing section embedded in a receiving portion of the receiving area of ​​the carrier element. Summary of the Invention

[0002] In such mounting units, the aim is to achieve the simplest possible installation within the housing of the load-bearing components.

[0003] If the mounting unit has a fixing unit supported on the receiving area when the mounting unit is fixed in the receiving area, and wherein the fixing unit is connected to the housing, especially to the second section of the housing, when the mounting unit is fixed in the receiving area, then the installation can be made as simple as possible.

[0004] Such mounting units can in particular include a connector for a trailer that can be connected to a motor vehicle or for a load-bearing component, and / or a control unit for components of the load-bearing unit, and / or a control unit for components of the trailer or load-bearing component.

[0005] Such a solution can be implemented in a particularly simple and low-cost manner.

[0006] In order to secure the housing to the receiving area, it is preferable to provide at least one protrusion on the housing, especially on the second section of the housing, which is embedded in a recess provided in the receiving area, especially in the receiving area, and torsionally fastens the housing to the receiving area, thereby presupposing a single and definite orientation of the housing in the receiving area.

[0007] In theory, the at least one protrusion can be located at any position on the housing, especially at any position on the second section of the housing.

[0008] It is particularly advantageous that the at least one protrusion is formed on the second section of the housing that is in contact with the first section of the housing, so as to achieve torsional fastening of the housing near the first section of the housing.

[0009] Even better, multiple protrusions are provided on the housing, especially on the second section of the housing, and each of these protrusions is embedded in a recess provided on the receiving area, especially in a recess provided in the receiving area.

[0010] To date, no further explanation has been given regarding the support of the fixing unit in the receiving area in conjunction with the description of the solution of the present invention.

[0011] One particularly advantageous solution stipulates that the housing, especially the second section of the housing, is supported on the receiving area by means of a fixing unit to prevent movement opposite to the insertion direction.

[0012] Of particular advantage is that the fixing unit includes a fixing element supported on a second outer side opposite to the first outer side of the receiving area.

[0013] The fixing element is connected to the housing section, especially the second housing section, in different ways.

[0014] An advantageous solution specifies that the fixing element includes a retaining anchor that extends between the inner wall of the receiving channel of the housing second section and the receiving portion, and is capable of being fixed to the supporting receiving portion of the housing, especially when the mounting unit is fixed to the receiving area.

[0015] In particular, it is specified that the anchor is provided with a locking element on the end side, which is embedded in the locking receiving part of the corresponding support receiving part when the installation unit is fixed.

[0016] The construction of these locking receptacles particularly enables them to cooperate with locking elements and to be fixed relative to each other in different locking positions in a simple manner, so as to compensate for installation tolerances in the receptacle area in a simple manner, which are caused by the installation tolerances arising from the setting of fixing elements at slightly different intervals from the support receptacles.

[0017] In the simplest case, the fixing element is constructed such that it includes a support body, particularly configured as an annular body, and is particularly capable of radially abutting against the receiving area outside the second section of the housing.

[0018] In order to securely and reliably fix the support body, the support body is equipped with support protrusions. The support protrusions are constructed such that they abut against the second outer side of the receiving area and support the receiving area when the installation unit is assembled.

[0019] In contrast to the setting of the retaining anchor, another preferred solution alternatively specifies that the fixing unit includes bolt anchors for fixing the support body, which extend between the inner wall of the housing second section and the receiving channel of the receiving part, and are embedded in the support receiving part of the housing at the end side.

[0020] In this case, it is preferably specified that the bolt anchor can be screwed into the bolt receiving portion provided in the support receiving portion of the housing.

[0021] No further explanation has been given regarding the support housing to date.

[0022] The support housing can be provided, for example, on the first section of the housing, or integrated, for example, into the first section of the housing.

[0023] One particularly advantageous solution specifies that the support housing is located on the second section of the housing.

[0024] It is particularly advantageous that at least one protrusion of the second segment of the housing is configured as one of the support receptacles, wherein it is particularly desirable if each of these protrusions of the second segment of the housing is configured as a support receptacle simultaneously.

[0025] No further explanation has been given regarding the construction of the support structure to date.

[0026] The support can, in principle, extend in a plane parallel to the second outer extension.

[0027] An advantageous solution specifies that the support arches toward the inlet side of the second section of the housing away from the first section of the housing, and that the anchor or bolt is anchored to the support in the area of ​​the support at the maximum distance from the inlet side.

[0028] The advantage of this solution is that the support body thereby necessarily arches towards the second outer side of the receiving area, and thereby first abuts against the outer side of the receiving area by means of the area between each retaining anchor or bolt anchor, and can abut against the outer side of the receiving area by means of the tension increased by prestress on the retaining anchor or bolt anchor.

[0029] Another advantageous solution to the task mentioned at the beginning, alternatively or supplementally to the current solution, is that the fixing element is equipped with a fixing tongue, which can be fastened to the fixing section of the second section of the housing, thereby enabling a particularly simple fixation of the fixing element on the second section of the housing.

[0030] If the second section of the housing extends beyond the second outer side of the housing by means of the fixing section when the mounting unit is fixed on the receiving area, then the fixing element can be fixed on the second section of the housing in a particularly simple way.

[0031] Furthermore, the fixing element is preferably constructed such that it has a flat region extending substantially parallel to a plane extending transversely to the central axis, the flat region carrying a fixing tongue extending radially relative to the central axis.

[0032] Flat areas can be constructed in different ways here.

[0033] One advantageous solution specifies that, in the state where the mounting unit is assembled on the receiving area, the flat area rests against the second outer side, thereby the flat area simultaneously forms a support.

[0034] In this case, in order to utilize the fixing element to simultaneously keep the cable guide device abutting against the carrier element, it is preferably specified that the fixing element has a retaining bow that engages the cable guide device from above and, in turn, allows the cable guide device to abut against the carrier element.

[0035] According to another alternative solution of the invention, the task mentioned at the beginning specifies that the fixing unit includes a bayonet connector and a fixing flange, the fixing flange being able to be fixed to the second section of the housing by means of the bayonet connector.

[0036] Here, a fixed flange is provided, for example, on the end cap for the second section of the housing.

[0037] In the same case, it is preferably specified that when the mounting unit is assembled on the receiving part, the fixing flange abuts against the second outer side of the receiving area.

[0038] Another advantageous solution to the task mentioned at the beginning stipulates that the fixing unit includes a fixing protrusion held on the second section of the housing.

[0039] In this case, the possibility of a suitable destination lies in the fact that the housing, when installed on the receiving area, is supported on the steps in the receiving area by means of a fixed protrusion, especially on the steps in the receiving area.

[0040] This can be particularly advantageously achieved by configuring the fixed protrusion to move spontaneously into the support position, in which the fixed protrusion is supported on the steps of the receiving area by means of the support side.

[0041] This makes it particularly easy to achieve that the fixed protrusion is integrally formed on the second section of the housing.

[0042] It is specifically stipulated here that the fixed protrusion extends in the radial direction and / or in the circumferential direction surrounding the second section of the housing.

[0043] Specifically, it is specified that the fixed protrusion is movable relative to the second section of the housing in at least the radial direction by means of elastic deformation.

[0044] Alternatively or supplementally, the fixed protrusion may be movable relative to the second segment of the housing in at least the circumferential direction around the second segment of the housing through elastic deformation.

[0045] A particularly advantageous design provision is that the fixed protrusion is constructed in the form of a thin sheet extending transversely to the step surface, the sheet being connected to the second section of the housing on its longitudinal side.

[0046] What is particularly advantageous here is that the sheet has a support edge extending laterally to the longitudinal side, and the sheet is supported on the stepped surface of the receiving area by means of the support edge.

[0047] Furthermore, it is preferably specified that the fixed protrusion has a turning edge extending laterally to the longitudinal side, which, when abutting against the inner wall of the receiving channel, deforms the fixed protrusion in the radial and / or circumferential direction, so that the second section of the housing, together with the fixed protrusion, can move through the receiving channel from the first receiving side until it reaches the steps of the receiving area, especially in the receiving section.

[0048] If the fixed protrusion with supporting edge has a defined position relative to the first section of the housing, the problem is that the tolerance between the step, especially the step surface of the step, and the first outer side of the predetermined position of the first section of the housing in the receiving area will not be compensated.

[0049] Therefore, an advantageous solution stipulates that when there are many fixed protrusions, the different fixed protrusions are arranged at different intervals from the first section of the housing by means of their supporting edges.

[0050] It is possible to compensate for the different tolerances between the step and the step surface by means of a number of fixed protrusions, specifically, at least a portion of the fixed protrusions can be radially extended when reaching the step during the insertion of the mounting unit and supported on the step surface by means of support edges.

[0051] Another advantageous solution to the task mentioned at the beginning stipulates that the fixing unit includes a number of fixing tongues held on the second section of the housing.

[0052] Here, the fixing tongue is preferably integrally formed on the second section of the housing.

[0053] To date, no further explanation has been given regarding the orientation of the fixation tongue.

[0054] One advantageous solution stipulates that the retaining tongue extends approximately parallel to the insertion direction, and therefore also parallel to the central axis.

[0055] Furthermore, it is preferably specified that, in the radial direction relative to the central axis of the second section of the housing, a wedge-shaped object can be used to load the fixing tongue, thereby allowing the fixing tongue to abut against the receiving area, especially against the inner wall of the receiving channel, and to be wedged tightly against the inner wall.

[0056] The inner wall of the receiving channel is preferably constructed to expand in the area where the fixing tongue rests, especially to expand in a conical shape towards the second outer side.

[0057] Another favorable solution stipulates that the wedge is constructed as a ring, wherein the wedge is not necessarily a closed ring, but can also be an open ring.

[0058] The wedge has sufficient self-stability to apply radially outward loading to the fixing tongue, abutting against the receiving channel and wedging tightly against the inner wall of the receiving channel, particularly towards the receiving area and especially towards the receiving channel.

[0059] However, a particularly advantageous configuration of the wedge can be achieved when the wedge is supported and guided on the opposite side of the fixing tongue on the housing, for example, when it is supported and guided on the end cap of the housing, so that the wedge only needs to have limited self-stability in order to load the fixing tongue in the radial direction.

[0060] For secure and reliable fixation of the wedge, it is preferably specified that the wedge is fixed in the position where the wedge is loaded against the fixing tongue by a locking element.

[0061] Here, the locking element can either function between the wedge and the retaining tongue, or it can function between the wedge and the end cap when the end cap is present and in action.

[0143] Figure 1 The motor vehicle shown and marked as 10 in general includes a body 12, which carries a bumper unit 16 in the rear region 14.

[0144] A transverse support body 22, integrally marked with 20, is provided on the rear side 18 of the rear region 14 covered by the bumper unit 16. It is fixed to the rear region 14 of the vehicle body 12 by a side support body 24, which is fixed, for example, in such a way that the side support body 24 extends parallel to the longitudinal direction 26 of the vehicle body 12 and is fixed to the rear region in the side region 28 of the rear region 14.

[0145] Here, the lateral support 22 is disposed between the rear side 18 of the rear region 14 and the bumper unit 16, and is covered by the bumper unit 16.

[0146] The bearing unit 20 is further equipped with a support unit marked with an integral 30, such as... Figure 2 As shown, the support base 32 of the support unit is connected to the transverse load-bearing body 22.

[0147] The support unit 30 further includes a support element generally marked 34, which is connected to a first end 42 of a support element generally marked 40, also included in the support unit 20, particularly configured as a ball neck, which extends from the first end 42 to a second end 44 and carries a coupling element generally marked 46 on its second end 44, which is thus carried by the support unit 20 and configured, for example, as a coupling ball.

[0148] The support element 34 may be a support element that is fixedly connected to the support base 32, or it may be a support element that can be detachably assembled onto the support base 32.

[0149] However, in Figure 2 In the illustrated solution, the support element 34 can alternatively serve as a pivot support element, capable of pivoting relative to the support base 32 about a pivot axis marked 36, thereby allowing the engagement element 40 to be... Figure 2 The working position A, shown by the solid line, pivots into the rest position R, shown by the dashed line. In this rest position, the bearing element 40 extends transversely from the support base 32 in the longitudinal direction 26 of the vehicle body 12, and thereby extends particularly along the transverse bearing 22.

[0150] In this way, the support element 40 extends transversely to the vertical longitudinal mid-plane 38 of the vehicle body 12 and also transversely to the vertical longitudinal mid-plane 38 of the support unit 20 in the rest position R shown by the dashed line, wherein the vertical longitudinal mid-plane 38 extends parallel to the longitudinal direction 26.

[0151] Furthermore, the pivot axis 36 preferably extends transversely to the vertical longitudinal intermediate surface 38, but also obliquely to the longitudinal intermediate surface, especially relative to the vertical longitudinal intermediate surface, at an angle of less than 90°, wherein the angle is, for example, less than 70° or especially greater than 20°.

[0152] Figure 3 An enlarged view shows an embodiment of such a bearing element 40, particularly an embodiment of a ball neck, wherein the bearing element 40 is fixedly connected to, and preferably formed on, the support element 34, and in this case, the support element 34 is configured as a pivot support element so as to be pivotally supported on the support base 32.

[0153] In the illustrated embodiment of the support element 40, the support element carries, in particular, a spherical attachment 48 at its second end, which has a surface that extends cylindrically relative to the sphere's central axis and extends around the sphere's central axis 50 at radial intervals smaller than the radius of the engaging sphere 46.

[0154] like Figure 3 As shown, in the illustrated embodiment of the carrier element 40, the carrier element has a receiving region 60 integrally integrated into the carrier element 40, preferably configured as an annular body 62, which is located between a first segment 64 and a second segment 66, wherein the first segment extends from a first end 42 of the carrier element 40 to the annular body 62, and the second segment extends from the annular body 62 to the second end 44 of the carrier element 40.

[0155] The annular body 62 surrounds the receiving portion, marked 72, which extends, for example, in the form of a perforation, from a first outer side 74 of the annular body 62 to a second outer side 76 of the receiving region 60. The receiving portion is configured, for example, to have a central axis 78 extending transversely to a vertical longitudinal intermediate surface 38, and the central axis can be inclined, for example, at an acute angle of 5° to 30° relative to a vertical line relative to the vertical longitudinal intermediate surface 38. Figure 3 , Figure 4 ).

[0156] The receiving portion 72 is constructed, in particular, by a receiving channel 82 having an inner wall 84 that is in contact with a first outer side 74 of the receiving region 60. The inner wall has a wall region 86 that extends substantially conically relative to the central axis 78 and surrounds the central axis 78, narrowing from the outer side 74 to a narrow position 87. The inner wall also has a wall region 88 that expands conically from the narrow position 87 to a second outer side 76, thus extending at a greater radial distance from the central axis 78 at the transition to the second outer side 76 of the receiving region 60 than it does near the narrow position 87.

[0157] The receiving portion 72 houses a mounting unit, generally marked 100, configured as a socket, which is equipped with a housing 102 having a first housing section 104 that rests against and is particularly supported by the first outer side 74.

[0158] The second section 106 of the housing extends from the first section 104 of the housing towards the second outer side 76 and enters the receiving channel 82.

[0159] Here, the second section 106 of the housing is preferably integrally formed on the first section 104 of the housing, so that they enclose the inner space 108 of the housing, in which, for example, a plug-in element 112, a wiring element 114 combined with the plug-in element and / or a circuit are provided, and in some cases, a sensor is also provided.

[0160] For example, by closing the cover 116 of the first section 104 of the housing, the plug-in element 112 disposed in the inner space 108 of the housing becomes accessible. The cover is pivotable relative to the first section 104 of the housing by means of a hinge 118 and is disposed on the side of the first section 104 of the housing opposite to the second section 106 of the housing, before the first outer side 74, so that the opening 120 of the housing 102 is accessible by the pivoting of the cover 116.

[0161] like Figure 5 and Figure 6 As shown, the second segment 106 of the housing is constructed such that the second segment 106 of the housing is connected to the first segment 104 of the housing and has at least one protrusion 122, preferably one protrusion 122 on each of the opposite sides, wherein each of the protrusions 122 extends into a recess 124 in the wall region 86 that extends radially relative to the central axis 78, and the recess 124 is adapted to the shape of each protrusion 122 such that the housing 102 of the mounting unit can be torsionally fixed in the receiving portion 72 by the cooperation of each protrusion 122 with the corresponding recess 124.

[0162] In this way, through the cooperation of each protrusion 122 with the corresponding recess 124, a single and definite orientation of the housing 102 of the mounting unit 100 is obtained, and thus a single and definite orientation of the cover 116 and, for example, the plug-in element 112 is also obtained.

[0163] Other examples Figure 7 As shown, the housing 102 is provided with an inlet opening 128 on its inlet side opposite to the first housing section 104. The inlet opening can be closed by an end cap marked 132, wherein the end cap 132 has an end wall 134 and a cylindrical attachment portion 136 extending from the end wall 134. The attachment portion can be introduced into the housing interior space 108 through the inlet opening 128 so as to achieve a sealing closure between the second housing section 106 and the cap 132.

[0164] The end cap 132 is also equipped with a bushing-shaped cable guide device. When the end cap 132 is placed on the second section 106 of the housing, the cable can be introduced into the housing space 108 through the cable guide device.

[0165] Therefore, as Figure 8 As shown, the end cap 132 closes the internal space 108 of the housing on one side opposite the cap 116, wherein, as Figure 5 As shown, the cylindrical attachment portion 136 can be sealed to the wall of the second section 106 of the housing.

[0166] like Figure 3 As shown, in order to fix the housing 102 in the receiving portion 72, the housing 102 having the second housing segment 106 is inserted in the receiving portion marked 72 in the insertion direction 142 and preferably parallel to the central axis 78, until the housing 102 abuts against the first outer side 74 of the receiving area 60 with the first housing segment 104 abutting against it.

[0167] This is done before the end cap 132 is assembled, so that when the housing 102 of the mounting unit 100 is inserted into the receiving portion 72, the end cap 132 is placed only after the lead cable introduced by the cable guide device 138 is connected to the wiring element 114.

[0168] In this case, the cable guiding device 138 is preferably as follows: Figure 9 As shown, the cable guide device 138 is located in a recess 144 in the second outer side 76 of the carrier element 40 relative to the receiving portion 72, thereby being substantially protected by the carrier element 40 from external mechanical influences.

[0169] pass Figures 7 to 10 The fixing unit, configured as a fixing element 150, shown in the figure, is used to fix the housing 102. The fixing element in the first embodiment has a support body 152, which includes, for example, a support protrusion 154 on one side, so that the support body can abut against the second outer side 76 for support on the second outer side.

[0170] Furthermore, the support body 152 is provided with retaining anchors 156 between these support protrusions 154, and these retaining anchors are provided with locking elements 158 at their ends opposite to the support body 152, the locking elements being as follows: Figure 12 As shown, the locking receiving portion 162 on one side of the protrusion 122 can be engaged, so that the fixing element 150 acts on the housing 102 in the region of the protrusion 122 by its support on the second outer side 76 in the assembled state, thereby ensuring that the housing 102 does not move in the receiving portion 72 opposite to the insertion direction 142.

[0171] The fixing element 150 is preferably provided with a support 152 of at least slightly elastic construction, which arches slightly toward the inlet side 130 and thus also toward the second outer side 76, such that the support protrusion 154 is positioned relative to the support 152 in the region of the retaining anchor 156 attached to the support and protrudes toward the second outer surface 76. The compression of the fixing element 150 toward the second outer side 76 and the insertion of the retaining anchor 156 with the locking element 158 ​​into the locking receiving portion 162 thus cause the support 152 to undergo a reduced arching deformation, so that the support rests against the second outer side 76 and thus holds the first housing section 104 of the housing 102 against the first outer side 74 under load.

[0172] By enabling the locking element 158 ​​to lock in different positions within the locking receiving portion 162, for example by using a longitudinal range larger than the corresponding locking element 158, Figure 12 The locking receiving portion 162 shown allows the locking element 158 ​​to be locked in different positions, and can compensate for the tolerance in terms of the spacing between the outer side 74 and the outer side 76 when the fixing element 150 is locked with the housing 102.

[0173] This makes the joining element 40 a forging, and therefore the receiving area 60 is also a forging, resulting in dimensional tolerances between the outer sides 74, 76, but these tolerances can be compensated for when the mounting unit 100 is assembled in the manner described above.

[0174] exist Figures 12 to 17 In the second embodiment shown, the same elements as in the first embodiment are given the same reference numerals, so that reference can be made to the entire contents of the first embodiment in its description.

[0175] like Figure 14 As shown, compared to the first embodiment, the fixing unit configured as fixing element 170 has a support body 172 configured as a ring and a through hole 174, into which a bolt anchor 176 can be inserted. The bolt anchor 176 can be screwed into the bolt opening 178 of the protrusion 122, so as... Figure 13 The support 172 is brought against the second outer side 76 of the receiving area 60 by means of the bolt anchor 176, thereby tensioning the support 172 and the first section 104 of the housing against the outer side 74.

[0176] In addition, such as Figure 17As shown, the support 172 also deforms, causing the sub-region 182 of the support 172 located between the perforations 174 to continue extending toward the outer side 76, thereby causing the bolt anchor 176 to be inserted into the bolt receiving portion 178, causing deformation in the support 172. This deformation generates a continuous elastic force between the support 172 and the first segment 104 of the housing, so as to securely and reliably fix the housing 102 in the receiving portion 72 without gaps.

[0177] Tolerances can also be compensated by bolt anchors 176 that can be screwed into the bolt receiving portion 178.

[0178] like Figures 18 to 22 As shown, in the third embodiment of the mounting unit 100 according to the present invention, the same reference numerals are used for the same elements as in the foregoing embodiments, so that all the contents of the foregoing embodiments can be referenced.

[0179] However, in the third embodiment, the second segment 106′ of the housing with the fixing segment 192 extends beyond the second outer side 76 in the direction of the central axis 78, wherein the fixing segment 192 has a circumferential retaining surface 194 for fixing the unit, wherein the fixing unit includes a fixing element generally marked 200.

[0180] The fixing element 200 is configured as a ring 202, wherein the ring 202 has a flat region 204 extending laterally to, and preferably perpendicularly to, the central axis 78, and for stability, an outer flange 206 extending laterally to the flat region 204 extends relative to the flat region.

[0181] The flat region 204 is preferably located in a plane extending transversely to, and in particular perpendicularly to, the central axis 78, and the fixing tongue 208 is also located in this plane. The fixing tongue extends radially inward beyond the flat region 204 and toward the retaining surface 194 of the fixing segment 192 so as to grip the retaining surface 194 when the annulus 202 is pushed. A slight deformation occurs in the region of the fixing tongue 208 when the annulus 202 of the fixing unit 200 is pushed onto the fixing segment 194. The fixing tongue rests its tip 212 against the retaining surface 194 and is preferably gripped in the material of the fixing segment 192 by embedding.

[0182] If the fixing section 192, and typically the entire housing 102, is made of plastic, and the fixing unit 200, especially the annular body 202, is constructed of metal, the fixing tongue 212 is, for example, embedded in the material of the fixing section 192, thereby fixing the fixing tongue 208 on the retaining surface 194. Thus, the first housing section 104, which is fastened to the second housing section, also remains against the first outer side 74, and the fastening of the fixing unit 200 on the second outer side 76 enables a tight, tolerance-insensitive fixation of the entire mounting unit 100 in the receiving portion 72.

[0183] The preferred configuration of the fixing tongue 208 is such that the attachment portion of the fixing tongue 208 on the flat region 204 is also provided with a void portion 214, which contributes to the greater flexibility of the fixing tongue 208 in the direction of the central axis 78, and thus contributes to the greater elasticity of the fixing tongue 208 relative to the annular body 202.

[0184] Furthermore, in the third embodiment, a retaining bow 216 is formed on the fixing unit 200, particularly on the annular body 202, which retains the cable guide 138 in the region of the cable guide 138 of the end cap 132 toward the recess 144, forcefully holding the cable guide 138 in the bearing element 40, and thus simultaneously fixing the cable guide 138 in the recess 144. Figure 21 , Figure 22 ).

[0185] exist Figures 23 to 27 In the fourth embodiment shown, the same elements as in the foregoing embodiments are given the same reference numerals, so that all the contents of the foregoing embodiments can be referred to.

[0186] like Figures 23 to 27As shown, compared to the previous embodiment, the end cap 132' can be fixed to the second segment 106 of the housing by means of a fixing unit 220 including a bayonet-type connecting portion 221. The connecting body 222 of the bayonet-type connecting portion 221 is provided around the inlet opening 128 on the housing segment 106, and the connecting receiving portion 226 of the bayonet-type connecting portion 221, having an insertion area 228, is provided in the cylindrical attachment portion 224 of the end cap 132. The attachment portion is constructed such that it surrounds its outer side. The second section 106 of the housing, through the inlet section, allows the connecting body 222 to move into the connecting receiving portion 226 when the end cap 132' is placed on the second section 106 of the housing. By rotating the end cap 132', the connecting body 222 of the bayonet-type connecting portion can move into the bayonet receiving portion 232 of the connecting receiving portion 226. Here, the connecting body 222 reliably ensures that the end cap 132' is not lifted from the second section 106 of the housing.

[0187] Furthermore, the fixing unit 220 includes a fixing flange 234 formed on the end cap 132' of the fourth embodiment, which is fixedly connected to the end cap 132'. When the end cap 132' is fixed to the second section 106 of the housing, the fixing flange abuts against the second outer side 76 of the receiving area 60, and thus fixes the mounting unit 100 in the receiving portion 72 when the first section 104 of the housing abuts against the outer surface 74.

[0188] exist Figures 28 to 30 In the fifth embodiment shown, the wall region 88 of the receiving portion 72′ is provided with a step 242, which has a step surface 244 facing the second outer side 76.

[0189] like Figure 29 and Figure 30 As shown, in order to fix the second section 106 of the housing in the receiving portion 72', the second section 106 of the housing is provided with a fixing unit 250, which includes at least two fixing protrusions 252, preferably including a plurality of fixing protrusions 252, wherein each fixing protrusion 252 extends toward the second section 106 of the housing in a radial direction 254 on the one hand, and extends in a circumferential direction 256 around the second section of the housing on the other hand.

[0190] Each of these fixing protrusions 252 is specifically configured as a sheet 251 extending parallel to the central axis 78 or insertion direction 142, and is elastically movable relative to the second segment 106 of the housing, wherein each of these fixing protrusions 252 extends independently away from the second segment 106 of the housing in a radial direction 254 without the influence of external forces. For this purpose, the sheet 251 is connected to the second segment 106 of the housing by means of a longitudinal side 253 extending substantially parallel to the central axis 78 or insertion direction 142.

[0191] Each fixed protrusion 252 can thus be supported on the step surface 244 by means of the support edge 258 extending transversely to the longitudinal side 253 without the influence of external forces, thereby ensuring that the housing 102 will not move out of the receiving channel 82 in a direction opposite to the insertion direction 142.

[0192] Each of these fixing protrusions 252 further includes a turning edge 262 extending obliquely to the insertion direction 142 and transversely to the longitudinal side 253. This turning edge contacts the inner wall 84 of the receiving channel 82 as the housing 102 moves in the insertion direction 142, thereby deforming each fixing protrusion 252 so that it moves radially 254 onto the second segment 106 of the housing, starting from its original radial extension relative to the second segment 106. This allows the housing 102 to be inserted into the receiving channel 82 while the fixing protrusions 252 slide against the inner wall 84, until the supporting edge 258 reaches the step surface 244. The fixing protrusions 252 then extend radially outward again and return to their original shape, in which each fixing protrusion 252 contributes to securing the housing 102 within the receiving portion 72 by means of the supporting edge 258.

[0193] Especially Figure 29 , Figure 30 As shown, for example, three sets of such fixing protrusions 252 are provided on the second section 106 of the housing, wherein each set includes, for example, three fixing protrusions 252, and the three sets of fixing protrusions 252 are arranged with the same angular spacing such that the second section 106 of the housing is symmetrically supported on the stepped surface 244 of the receiving portion 72'.

[0194] Here, the end cap 132 in the fifth embodiment is applied in the same manner as in the previous embodiments to close the inlet opening 128 leading into the second section 106 of the housing.

[0195] In the fifth embodiment, in order to secure the second segment 106 of the housing to the receiving portion 72' in a torsion-resistant manner, two additional protrusions 122 are formed on the second segment 106 of the housing, which are embedded in the recesses 124 in the receiving portion 72, in the same manner as described in the previous embodiments.

[0196] Furthermore, elements that are identical to those in the foregoing embodiments and constructed in the same manner in the fifth and sixth embodiments below are given the same reference numerals, thereby enabling reference to the entirety of the foregoing embodiments.

[0197] like Figures 31 to 33 In a variant of the fifth embodiment shown, in the sixth embodiment, the fixing protrusion 252 is formed around the second segment 106 of the housing, which serves as the fixing unit 250, thereby obtaining the entire annular edge 270 of the fixing protrusion 252, and the fixing protrusion 252 is constructed in the same manner as in the fifth embodiment.

[0198] However, in contrast to the fifth embodiment, the sixth embodiment specifies that the support edges 258 of the fixing protrusions 252 are provided at different intervals from the first segment 104 of the housing. For example, one or more fixing protrusions 252 together with their support edges 258 are provided at a defined interval from the first segment 104 of the housing, and this interval is different from the defined interval of the support edges 258 of other fixing elements 252.

[0199] The fixed protrusion 252 with supporting edge 258 is arranged at a different distance from the first segment 104 of the housing, so that the tolerance in terms of the distance between the step surface 244 in the receiving part 72 and the first outer side 74 that the first segment 104 of the housing abuts can be compensated. The entire receiving part 72 and the receiving area 60, as well as the step 242 with step surface 244, are manufactured as forgings, which determines these tolerances and thereby allows the tolerance in the distance between the outer side 74 and the step surface 244 to be generated.

[0200] If the tolerance exists in the region of different intervals between the support edge 258 of the fixed protrusion 252 and the first segment 104 of the housing, then the fixed protrusion 252 will always be located on the step surface 244 with or without contact, and therefore it is possible that when the housing 102 is inserted, the fixed protrusion will move to its original position in the radial direction 254, and thus secure the housing 102 in the receiving portion 72 with substantially no gaps.

[0201] The construction of the end cap 132 has not yet been described in detail. The end cap 132 may or may not be equipped with a cable guide device 138.

[0202] In all cases, the end cap 132 closes the inlet opening 128 into the second section 106 of the housing in the same manner as in the first, second, third, and fifth embodiments.

[0203] exist Figures 34 to 37 In the seventh embodiment shown, the same reference numerals are used for the same elements as in the foregoing embodiments, so that reference can also be made to the contents of all the foregoing embodiments.

[0204] In contrast to the fifth embodiment, in the seventh embodiment, the second segment 106″′ of the housing is constructed such that at least two, preferably multiple, fixing tongues 272, for example, provided as circumferential edges, are formed as fixing units 270 on the outer side of the second segment of the housing. The fixing tongues extend along the outer side 276 of the second segment 106″′ of the housing and, in some cases, extend beyond the second segment of the housing.

[0205] For example, the retaining tongue 272 is connected to the second segment 106 of the housing via a retaining piece 274, and extends beyond the inlet opening 128, for example, at a distance from the outer side 276 of the second segment 106 of the housing, to the wedge-shaped end region 278.

[0206] However, in this embodiment, the wiring element 114″′ is not disposed in the housing space 108 of the housing second section 106″′, but can be placed on the housing second section 106″′ and has a cylindrical guide 282 surrounding the outer side 276 of the housing second section 106″′. The guide extends substantially to the retaining piece 274 of the fixing tongue 270 and guides the wiring element 114, wherein the wiring element extends into the housing second section 106 by means of the cylindrical attachment 284 through the inlet opening 128 of the housing second section 106, so that the sealing element 286 can be placed between the cylindrical attachment 284 and the inner surface of the housing second section 106″′ to achieve a sealing seal.

[0207] Furthermore, the wiring element 114 has a locking surface 292 in the region 288 adjacent to the second outer side 76, on which the end cap 132″′ can be placed, and the end cap 132″′ can lock with the locking surface by means of the inner surface 294 of its cylindrical attachment portion 136.

[0208] To allow the wedge-shaped end regions 278 of the locking tongue 272 to spread apart, a wedge-shaped body 302 can be inserted between the wall surface 296 of the cylindrical attachment portion 136 of the end cap 132″′, which can be locked by means of the locking profile 292, and the wedge-shaped end regions 278 of the locking tongue 272. The wedge-shaped body is supported on the outer side 304 of the wall surface 296 of the cylindrical attachment portion 136 of the end cap 132″′, and acts on the wedge-shaped end regions 278 so that the end regions are forcefully loaded and abut against the conically enlarged wall region 88 near the second outer side 76 of the receiving region 60, thereby securing the housing 102 to prevent it from dislodging from the receiving portion 72 due to movement opposite to the insertion direction 142.

[0209] In order to fix the wedge 302 in the position of its wedge-fitting fixing part 272, the fixing tongue 272 and the wedge 302 are provided with locking elements 312 and 314 embedded in each other on their mutually abutting sides 306 and 308.

[0210] Similarly, in this solution, despite manufacturing tolerances, the mounting unit 100 can still be easily and seamlessly assembled into the receiving area 60.

[0211] For all other features that are the same as those in the foregoing embodiments, please refer to the entire contents of the foregoing embodiments.
