Angled connector and method for assembling an angled connector

Description

[0001] The invention relates to an angled connector, in particular an angled push-pull connector, and a method for assembling or putting together an angled connector.

[0002] The invention lies in the field of connector technology, particularly in the field of circular connectors. A subtype of these connectors are angled connectors, which are designed at an angle and may have an angle of, for example, 90° adjacent to the insertion end of the connector, with which the connector is inserted into a complementary connector receptacle in a specific insertion direction. These connectors thus have an angle, which is why the insertion end is arranged at an angle to the cable end of the connector.

[0003] Especially with angled connectors, the problem arises that the angled cable end, when force is applied to the cable end, puts a great strain on the mechanical and / or electrical contact between the connector and the complementary connector receptacle, which can lead to mechanical damage and / or unreliable electrical connections.

[0004] Furthermore, CH 703474 A2 relates to a coaxial connector part with a base body on which a flange is formed. A clamping sleeve is attached to the flange, comprising an annular base and several clamping tongues arranged resiliently on this base, which have inwardly projecting detent edges. A release sleeve, which surrounds the clamping sleeve and interacts with the clamping tongues via a ramp, serves to lock the first connector part relative to a second, corresponding connector part.

[0005] US 10,490,937 B1 further relates to a quick-push-pull self-locking connector. This includes a first plastic core, a plurality of first terminals, a plurality of second terminals, a first shielding sleeve, a first housing, and a locking element.

[0006] WO 2010 / 114068 A1 further relates to a coaxial cable connector comprising a connector body made of cylindrically shaped conductive metal and a cylindrical interlocking section made of conductive metal.

[0007] WO 2018 / 041785 A1 further relates to an angled connector for pluggably connecting an electrical cable to a mating connector, wherein the angled connector comprises a housing with a plug part and a detachable angled section, a terminal assembly mounted in the housing with a plurality of electrical terminals supported by a terminal housing fixed in the plug part, and a wedging arrangement complementary to a wedging arrangement of the mating plug for angularly aligning the terminal assembly about a plug axis relative to the mating plug. The plug part and the angled section each comprise interlocking alignment elements configured such that the angled section can be positioned in various discrete angular orientations about the plug axis relative to the plug part.

[0008] Therefore, the object of the present invention is to provide an angled connector, in particular an angled push-pull connector, and a method for assembling an angled connector, which makes it possible to overcome the aforementioned disadvantages.

[0009] This problem is solved by the subject matter of the independent claims. Preferred embodiments are defined in the dependent claims.

[0010] One aspect concerns an angled connector according to claim 1.

[0011] Advantageously, the positive-locking arrangement of the insulating body in the first housing part and the positive-locking arrangement of the first housing part in the second housing part allow forces acting particularly on the second connector section and perpendicular to the insertion direction to be distributed across the elements of the first connector section, especially the insulating body, the first housing part, and the second housing part. This advantageously reduces stress on the mechanical and / or electrical connection between the connector and the complementary connector receptacle, thereby simultaneously improving or reliably establishing the electrical connection between the connector and the complementary connector receptacle.

[0012] Within the scope of the present invention, the circumferential direction of the first housing part and the circumferential direction of the second housing part are each understood to be a direction lying in a plane that is substantially perpendicular to the insertion direction. Furthermore, the circumferential direction is a direction extending along the circumference of the respective housing part.

[0013] Furthermore, the first connector section and the second connector section together can form a connector housing in which the cable is guided, at least partially. Preferably, the cable is arranged within the second connector section substantially parallel to the cable routing direction. In other words, the longitudinal direction of the cable within the second connector section is substantially parallel to the cable routing direction.

[0014] Preferably, the first housing part and / or the second housing part can be designed as a substantially elongated hollow body, preferably as a substantially hollow cylindrical body. The longitudinal axis of the first housing part and / or the longitudinal axis of the second housing part can run substantially parallel to the insertion direction. The longitudinal axis is understood to be the axis corresponding to the direction of the greatest extent of the first housing part or the second housing part, respectively. Furthermore, the longitudinal axis of the first housing part and the longitudinal axis of the second housing part can each form an approximate axis of symmetry of the respective housing part.

[0015] Furthermore, the insulating body can be arranged at least partially within the first housing part and / or at least partially within the second housing part. In particular, the first housing part can be arranged between the second housing part and the insulating body. Furthermore, the first housing part can be arranged at least partially within the second housing part. Specifically, for assembling the connector, the insulating body can be inserted into the first housing part, and the first housing part into the second housing part. For example, the insulating body can be inserted into the first housing part in the direction of insertion, and the first housing part can be inserted into the second housing part in the direction of insertion.It is understood that the connector can also be assembled in reverse, namely that the second housing part can be slid onto the first housing part in the opposite direction of insertion and that the first housing part can be slid onto the insulating body in the opposite direction of insertion.

[0016] Furthermore, the connector-side electrical contact means can have one or more electrical contact elements, for example, pins and / or sockets, each of which can be connected to and / or is connected to electrically conductive conductors or strands of the cable. Accordingly, the complementary connector-receptor-side electrical contact means can have one or more complementary electrical contact elements, for example, pins and / or sockets, which can be electrically connected to corresponding connector-side electrical contact elements, for example, by inserting the connector into the connector receptacle in the direction of insertion.

[0017] Furthermore, the insulating body can be made of a dielectric material, so that the connector-side electrical contact means are electrically isolated from other parts of the connector. In particular, the one or more connector-side electrical contact means of the insulating body are arranged on the insulating body in an electrically isolated manner from each other.

[0018] The insulating body has an anti-rotation element on the insulating body side, in particular a projection or a recess, and the first housing part has a complementary anti-rotation element on the first housing part side, in particular a recess or a projection, wherein in an assembled state of the connector, the insulating body-side

[0019] The anti-rotation element and the first anti-rotation element on the housing part engage in such a way that the insulating body is positively locked in the first housing part in the circumferential direction. In other words, the insulating body and the first housing part are not movable relative to each other in the circumferential direction of the first housing part when the connector is assembled.

[0020] Advantageously, by interlocking the anti-rotation element on the insulation body side and the first anti-rotation element on the housing part side, a torque acting on the insulation body and / or the first housing part can be transferred to the other element (the insulation body or the first housing part), thereby distributing the force on the insulation body and the first housing part.

[0021] Preferably, the anti-rotation element on the insulating body side can be formed on the outer circumferential surface of the insulating body, which faces the first housing part. For example, the insulating body can be designed as a substantially cylindrical body, with the anti-rotation element on the insulating body side being arranged on the outer surface of the insulating body. Furthermore, the cylinder axis of the insulating body can be substantially parallel to the insertion direction. Additionally, in the assembled state of the connector, the cylinder axis of the insulating body can substantially coincide with the longitudinal axis of the first housing part and / or the second housing part.

[0022] Furthermore, the first anti-rotation element on the housing side can be designed to be complementary to the anti-rotation element on the insulation body side. That is, if the anti-rotation element on the insulation body side is designed as a projection, then the first anti-rotation element on the housing side is designed as a complementary recess into which the anti-rotation element on the insulation body side can engage, and if the anti-rotation element on the insulation body side is designed as a recess, then the first anti-rotation element on the housing side is designed as a projection which can engage into the anti-rotation element on the insulation body side.

[0023] Advantageously, the anti-rotation element on the insulation body side and the first anti-rotation element on the housing part side are arranged in such a way as to define an orientation of the insulation body relative to the first housing part. In other words, the anti-rotation element on the insulation body side and the first anti-rotation element on the housing part side allow the insulation body to be inserted into the first housing part in exactly one orientation.

[0024] The second housing part has a second anti-rotation element on the housing part side, in particular a projection or a recess, wherein, in the assembled state of the connector, the second anti-rotation element on the housing part side and the first anti-rotation element on the housing part side engage with each other in such a way that the first housing part is positively locked in the second housing part in the circumferential direction of the second housing part. In other words, the second housing part and the first housing part are not movable relative to each other in the circumferential direction of the first housing part in the assembled state of the connector.

[0025] Advantageously, the interlocking of the second and first housing-side anti-rotation elements allows a torque acting on the insulation body and / or the first and / or the second housing part to be transferred to the other elements (the insulation body, the first housing part, and the second housing part, respectively), thus distributing the force across the insulation body, the first housing part, and the second housing part. In particular, the second housing-side anti-rotation element can be arranged on an inner side of the second housing part facing the first housing part.

[0026] Preferably, the first anti-rotation element on the housing part side can engage with the anti-rotation element on the insulation body side and simultaneously with the second anti-rotation element on the housing part side. For example, the first anti-rotation element on the housing part side can be provided as a recess into which the anti-rotation element on the insulation body side, designed as a projection, and the second anti-rotation element on the housing part side, also designed as a projection, engage together. Advantageously, it is therefore sufficient for the first housing part to have only a single first anti-rotation element on the housing part side.

[0027] As an alternative to a first anti-rotation element on the housing part designed as a recess, the first anti-rotation element on the housing part can be arranged on an outer side of the first housing part, which faces the second housing part, and on an inner side of the first housing part, which faces the insulating body. For example, the first anti-rotation element on the housing part can have a projection on the outer side of the first housing part and a projection on the inner side of the first housing part, which are arranged opposite each other with respect to the wall of the first housing part.Furthermore, the projection arranged on the inner side of the first housing part can engage in the anti-rotation element on the insulation body side, which is designed as a recess, and the projection arranged on the outer side of the first housing part can engage in the anti-rotation element on the housing part side, which is designed as a recess.

[0028] Preferably, the second housing part is movable relative to the first housing part along the insertion direction, wherein the path or range by which the second housing part can move relative to the first housing part is limited. In other words, the movement of the second housing part relative to the first housing part in the direction of insertion and against the insertion direction is limited.

[0029] Preferably, the first housing part can have a reboundable locking element which is designed to engage positively in the connector receptacle, and wherein preferably a movement of the second housing part relative to the first housing part along the insertion direction, in particular against the insertion direction, releases the locking element from engaging in the connector receptacle.

[0030] Advantageously, by moving the second housing part in the opposite direction to the insertion direction, the connector can be released from the complementary connector receptacle. The second housing part can also be considered an operating element, which a user actively moves in the opposite direction to release the connector from the connector receptacle. In particular, the second housing part can be arranged externally on the connector, making it accessible to the user.

[0031] Furthermore, the second housing part can have a through-opening through which the locking element of the first housing part can pass from the inside to the outside. Additionally, by moving the first housing part against the insertion direction, the locking element can be displaced along the longitudinal axis of the first housing part, thus releasing the locking element from engaging the connector receptacle. Furthermore, the locking element's rebound bearing can move it radially outwards, away from the longitudinal axis of the first housing part. Finally, in the assembled state of the connector, the locking element can limit the movement of the second housing part relative to the first housing part in the insertion direction.In particular, the through-hole and the locking element are arranged such that the through-hole strikes the locking element when the second housing element is moved in the direction of insertion.

[0032] Furthermore, the first housing part, designed as a hollow body, can have a spring element arranged in the housing wall or in the wall of the first housing part. The spring element can, in particular, be integrally formed with the first housing part and be formed by a recess in the housing wall that at least partially surrounds the spring element. The longitudinal direction of the spring element can extend essentially parallel to the insertion direction, with an end of the spring element located in the insertion direction not being connected to the first housing part and an end of the spring element located opposite the insertion direction being connected to the first housing part. Furthermore, the end of the spring element located in the insertion direction can have a locking element, for example in the form of a lug or a projection, on its outer surface facing the second housing part.

[0033] It is understood that the first housing part may have more than one locking element, and that the second housing part may accordingly have several through-holes.

[0034] Preferably, the connector can include a connecting housing part for joining the first and second connector sections. In particular, the connecting housing part joins the first connector section to the second connector section. Furthermore, the first connector section, the connecting housing part, and the second connector section form a housing in which the cable is guided up to the insulation body. The connecting housing part can also be designed to specify or define an angle between the first and second connector sections. In other words, the connecting housing part can determine the angle at which the second connector section is angled relative to the first connector section. The connecting housing part can also be a single piece and / or solid.

[0035] Preferably, the connecting housing part can have a first connection section that can be force-fitted to the first connector section. Advantageously, the first connector section can thus be easily connected to the connecting housing part, and the connecting housing part and the first connector section can be separated from each other without damage.

[0036] Preferably, the connector housing part can have a second connection section that can be positively connected to the second connector section, particularly along the cable routing direction. Advantageously, the second connector section can thus be easily connected to the connector housing part. In particular, the connector housing part and the second connector section can be slidably within each other to be positively connected. Furthermore, the connector housing part and the second connector section can be separated from each other without damage.

[0037] Furthermore, it can be provided that, to assemble the connector, the second connector section is first connected to the connecting housing part, and then the first connector section is connected to the connecting housing part. In particular, it can be provided that the connecting housing part is first pushed onto the second connector section in the insertion direction, and then the first connector section is positively connected to the connecting housing part. At the same time, the positive connection of the first connector section to the connecting housing part prevents the second connector section from being detached from the connecting housing part. In particular, in the assembled state of the connector, the first connector section is arranged on the connecting housing part in such a way that the second connector section cannot be detached from the connecting housing part.In other words, the first connector section secures the second connector section to the connection housing part.

[0038] Preferably, the first connector section can have a connecting element, rotatably mounted and arranged at least partially between the first housing part and the second housing part, which can be force-fitted to the first connector section. The connecting element can preferably be designed as a hollow body, for example as a nut, which can be screwed onto the first connector section, preferably a threaded one. The axis of rotation of the connecting element can coincide with the longitudinal axis of the first housing part or the second housing part. Furthermore, in the assembled state of the connector, the connecting element can be arranged between the first housing part and the second housing part in such a way that the connecting element cannot be detached from the first connector section in the opposite direction to the insertion direction.In particular, the connecting element may have a stop that can strike a complementary stop of the first housing part when the connecting element is moved relative to the first housing part in the opposite direction of insertion.

[0039] Furthermore, it can be provided that the first housing part is inserted or inserted into the connector in the insertion direction to assemble the connector, or that the connector is pushed onto the first housing part in the opposite direction. The first housing part can thus be arranged section by section within the connector.

[0040] Preferably, the connector housing part can have a connector housing-side alignment element which extends from the first connection section in the insertion direction and which is designed to engage with a complementary housing-side alignment element of the first housing part in order to align the position of the first connector section with respect to the connector housing part.

[0041] Advantageously, the provision of the alignment element on the connecting housing part side and the complementary alignment element on the housing part side allows the first housing part to be aligned with the connecting housing part, so that the first housing part can be arranged in a predetermined orientation on the connecting housing part. The alignment elements can be designed as projections whose arrangement determines the orientation of the first housing part with respect to the connecting housing part. Furthermore, the alignment elements are arranged such that rotation of the first housing part relative to the connecting housing part about the longitudinal axis of the first housing part is prevented.

[0042] Preferably, the second connection section of the connector housing part can have two opposing guide elements on the connector housing side, and the second connector section can have guide elements on the connector section side that are complementary to the guide elements on the connector housing side. Furthermore, to connect the connector housing part to the second connector section, the guide elements on the connector housing side and the guide elements on the connector section side can interlock and be moved relative to each other essentially along the insertion direction.

[0043] Preferably, the interlocking of the guide elements on the connector section side and the guide elements on the connection housing side allows the connection housing part to be positively connected to the second connector section. Furthermore, the connection housing part is designed such that movement of the second connector section relative to the connection housing part against the insertion direction is limited.

[0044] Preferably, the longitudinal direction of the guide elements on the connector section side and the guide elements on the connection housing side can run essentially parallel to the insertion direction. Furthermore, the guide elements on the connector section side can be arranged opposite each other with respect to a cable located in the second connector section. Additionally, the guide elements on the connector section side and the guide elements on the connection housing side can be designed such that relative movement of the second connector section with respect to the connection housing part along the cable routing direction is prevented.

[0045] Preferably, the second connector section may further comprise: a cable securing element which surrounds the cable at least partially along the cable routing direction, a third housing part, and a fourth housing part which can be force-fitted to the third housing part, wherein the cable securing element is arranged at least partially in the third housing part and / or the fourth housing part.

[0046] Advantageously, the cable can thus be easily positioned and secured in the second connector section during connector assembly. Preferably, the third housing part can include the guide elements on the connector section side.

[0047] Preferably, the cable locking element, the third housing part, and / or the fourth housing part are designed as substantially elongated hollow bodies, preferably as substantially hollow cylindrical bodies, with their longitudinal axis running substantially parallel to the cable routing direction. To assemble the connector, the cable can be guided with one end in the cable routing direction first through the fourth housing part, then through the cable locking element, and subsequently through the third housing part. By connecting the fourth housing part and the third housing part, the cable is secured in the second connector section by means of the cable locking element. "Secured" means that the position of the cable is fixed with respect to the second connector section.

[0048] Preferably, the cable locking element can be designed to be deformable, wherein the cable locking element is deformable by the force-fit connection of the fourth housing part to the third housing part, such that the cable is secured in the second connector section. Furthermore, the cable locking element can be released by releasing the force-fit connection between the third and fourth housing parts, thus freeing the cable.

[0049] In particular, the cable locking element can be designed as a clamping socket that surrounds the cable, at least partially, along the cable routing direction. Furthermore, the cable locking element can have an outwardly directed projection that can engage with the third housing part to prevent rotation of the cable locking element relative to the third housing part about its longitudinal axis.

[0050] Preferably, the third housing part has the guide elements on the connector section side, which are arranged at an end of the third housing part lying in the cable routing direction.

[0051] Furthermore, it may be provided that the third housing part, the cable securing element, and the fourth housing part can be separated from each other without damage. Likewise, it may be provided that the first connector section and the second connector section can be separated from the connecting housing part without damage.

[0052] Preferably, the insertion direction and the cable routing direction form an angle of essentially 80° to 145°, more preferably 80° to 120°, and particularly preferably approximately 90° to each other. In other words, the second connector section is angled relative to the first connector section by an angle of essentially 80° to 145°, more preferably 80° to 120°, and particularly preferably approximately 90°. In particular, the longitudinal axes of the first connector section and the second connector section are arranged such that they intersect in the connector housing part and form an angle of 80° to 145°, more preferably 80° to 120°, and particularly preferably approximately 90°.

[0053] Preferably, the connector can have a spacer element which distances the insulating body from the connecting housing part in the direction of insertion.

[0054] The spacer element can, in particular, partially enclose the insulating body along the insertion direction. Preferably, a section of the insulating body along the insertion direction is not encompassed by the spacer element. In particular, the anti-rotation element on the insulating body side is not covered by the spacer element. Furthermore, the spacer element can be arranged, at least partially, in the connecting housing part and, in particular, in the first connecting section. The spacer element can preferably be formed by two symmetrically, preferably mirror-symmetrically, designed half-shell elements, which, when combined, form an elongated hollow body, preferably a substantially hollow cylindrical body, whose longitudinal axis runs substantially parallel to the insertion direction and coincides with the longitudinal axis of the insulating body.

[0055] Furthermore, it can be provided that the insulating body is arranged in a positionally fixed manner at an end of the spacer element located in the insertion direction, such that the position of the insulating body relative to the spacer element is unchanging along the insertion direction. In particular, the insulating body can have a positioning element on the insulating body side, which can engage with a complementary positioning element on the spacer element side, so that the insulating body and the spacer element are arranged in a form-fitting manner relative to each other along the insertion direction.

[0056] Furthermore, it may be provided that the spacer element, in the assembled state of the connector, is arranged at least sectionally along the insertion direction in the first housing part.

[0057] Preferably, the first connector section is designed to be positively engaged in the complementary connector receptacle in the circumferential direction of the first connector section. Advantageously, a torque acting on the connector, in particular a torque acting on the insulating body, the first housing part, and / or the second housing part, can thus be transmitted to the connector receptacle. Preferably, the second housing part is designed to be positively engaged in the complementary connector receptacle in the circumferential direction of the first connector section or in the circumferential direction of the second housing part. It can be provided that the circumferential direction of the first connector section runs in a plane that is oriented essentially perpendicular to the insertion direction.Furthermore, the circumferential direction of the first connector section can extend around the longitudinal direction of the first connector section. In particular, the second housing part can have an orientation aid that engages with a complementary orientation aid of the connector receptacle when the connector is inserted into the connector receptacle and / or is already inserted. The orientation aid is designed to prevent or block movement of the first housing part relative to the connector receptacle along the circumferential direction.

[0058] Furthermore, it may be provided that the first housing part, the second housing part, the insulating body, the connecting element, and the spacer element can be separated from each other without damage.

[0059] Another aspect concerns a method for assembling an angled connector according to claim 14.

[0060] Advantageously, the connector can be easily assembled using the proposed method.

[0061] Furthermore, the connector can be further developed according to the previous aspect.

[0062] Furthermore, step (b) of the method may provide that the cable is first guided through the fourth housing part, then through the cable securing element and then through the third housing part in the direction of cable routing, preferably with shielding of the cable between the cable securing element and the third housing part.

[0063] Furthermore, step (c) of the method may provide that conductors or strands of the cable are connected to the corresponding electrical contact elements on the connector side, for example by soldering. The method may also provide that, prior to step (d), the spacer element is positioned on the insulating body and on the third housing part. Subsequently, the connector housing part is positively connected to the second connector section or the third housing part, thereby positioning the spacer element at least partially within the connector housing part.

[0064] For steps (d) and (e) of the method, it may be provided in particular that the first housing part is first passed through the connecting element in the insertion direction and then the second housing part is pushed onto the first housing part in the opposite direction of insertion, so that the connecting element is rotatably mounted between the first and second housing parts. Subsequently, the first housing part can be pushed onto the insulating body in the opposite direction of insertion and aligned using the alignment element on the side of the connecting housing part.

[0065] The connector can then be positively connected to the first connection section of the connector housing part, thus securing the second connector section to the connector housing part. Furthermore, the third housing part can be positively connected to the fourth housing part.

[0066] The process steps can be carried out in the order mentioned above. However, individual process steps can also be carried out in a different order.

[0067] The invention is described in more detail below with reference to exemplary embodiments shown in the figures. Similar features of the exemplary embodiments are indicated by the same reference numerals. The figures show: Figure 1 shows an angled connector in a perspective view; Figure 2 shows an exploded view of the connector in a perspective view; Figure 3 shows a cross-section through the connector; Figure 4 shows another cross-section through the connector; Figure 5 shows another cross-section through the connector

[0068] Figure 1Figure 1 shows a perspective view of an angled connector 10, preferably configured as an angled push-pull connector. The connector 10 is designed to receive a cable 12 and to be connected to a complementary connector receptacle (not shown). Furthermore, the connector 10 is substantially L-shaped and has a substantially straight first connector section 14 and a substantially straight second connector section 16.

[0069] Furthermore, the first connector section 14 is designed to be connected to the complementary connector receptacle (not shown) in the direction of an insertion direction E. In particular, an end of the first connector section 14 located in the insertion direction E has an insertion section 15 which is preferably mechanically connectable to the complementary connector receptacle.

[0070] Furthermore, the connector 10 has a connecting housing part 18 which connects the first connector section 14 with the second connector section 16.

[0071] The cable 12 can be inserted into the connector 10 via the second connector section 16 in the direction of the cable routing direction K. Within the second connector section 16, the cable 12 is guided along the cable routing direction K. In other words, within the second connector section 16, the longitudinal direction of the cable 12 is essentially parallel to the cable routing direction K. The first connector section 14 and the second connector section 16 are angled relative to each other, so that the cable routing direction K and the insertion direction E run in opposite directions. Furthermore, the first connector section 14 has a longitudinal axis L1 and the second connector section 16 has a longitudinal axis L2, which intersect in the connector housing part 18.The longitudinal axes L1 and L2 enclose an angle α that determines the angular position of the second connector section 16 relative to the first connector section 14. In the illustrated embodiment, the angle α is essentially 90°. However, other angles α are also covered by the invention, in particular angles α in a range of 80° to 145° and preferably from 80° to 120°.

[0072] Figure 2 shows an exploded view of the in Figure 1 connector 10 shown. This shows Figure 2 The first connector section 14 comprises a first housing part 20, a second housing part 22, an insulating body 24, and a connecting element 26. Furthermore, the connector housing part 18 comprises a first connecting section 28 and a second connecting section 30.

[0073] By means of the connecting element 26, the first connector section 14 can be force-fitted to the connecting housing part 18 and in particular to the first connecting section 28.

[0074] The second connector section 16 comprises a third housing part 32, a cable locking element 34, and a fourth housing part 36. The third housing part 32 and the second connection section 30 are designed to be positively connected to one another. Furthermore, the assembled connector 10, comprising the first connector section 14, the second connector section 16, and the connection housing part 18, forms a housing in which the cable 12 is guided.

[0075] Furthermore, the insulating body 24 has a connector-side electrical contacting means 54, for example, one or more pins and / or sockets, which electrically connect the cable 12 to a complementary connector-receptacle-side electrical contacting means (not shown) of the complementary connector receptacle. The insulating body 24 can be made of a dielectric material such that the connector-side electrical contacting means 54 is electrically insulated from other elements of the connector 10, in particular from other connector-side electrical contacting means 54 arranged on the insulating body 24.

[0076] Furthermore, the first housing part 20, the second housing part 22, the third housing part 32, the fourth housing part 36, and the cable locking element 34 are designed as substantially elongated hollow bodies, preferably as a substantially hollow cylindrical body. In the assembled state of the connector 10, the longitudinal axes of the first housing part 20 and the second housing part 22 coincide with the longitudinal axis L1 of the first connector section 14. Furthermore, in the assembled state of the connector 10, the longitudinal axes of the third housing part 32, the cable locking element 34, and the fourth housing part 36 coincide with the longitudinal axis L2 of the second connector section 16.

[0077] The insulating body 24 can have a substantially cylindrical shape, wherein the cylinder axis of the insulating body 24 coincides with the longitudinal axis L1 of the first connector section 14 in the assembled state of the connector 10.

[0078] Further details of connector 10 are given below with reference to the Figures 3 to 5 explained in more detail.

[0079] Figure 3 This shows a cross-sectional view of connector 10 along the line in the Figure 1 AA line shown. Figure 4 shows a cross-sectional view of connector 10 along the line in the Figure 1 BB line shown. Figure 5 shows a cross-sectional view of connector 10 along the line in the Figure 1 CC line shown.

[0080] As from Figure 3As can be seen, in the assembled state of the connector 10, the insulating body 24 is arranged, at least section by section, along the insertion direction E in the first housing part 20. In particular, the insulating body 24 is positively locked in the first housing part 20 in the circumferential direction Ur of the first housing part 20. In other words, the insulating body 24 cannot be moved relative to the first housing part 20 in the circumferential direction Ur of the first housing part 20. The circumferential direction Ur lies in a fictitious plane, which is essentially perpendicular to the insertion direction E.

[0081] Furthermore, the first housing part 14 is arranged at least partially along the insertion direction E within the second housing part 22. In particular, the first housing part 20 is positively engaged in the second housing part 22 in the circumferential direction Ur of the first housing part 20. In other words, the first housing part 20 cannot be moved relative to the second housing part 22 in the circumferential direction Ur of the first housing part 20. Furthermore, the second housing part 22 has a circumferential direction Ur which runs substantially parallel to the circumferential direction Ur of the first housing part 20.

[0082] For positive locking connection of the insulating body 24 with the first housing part 20, the insulating body 24 has an anti-rotation element 38 on its outer surface (see Figures 2 , 3 and 4Furthermore, the first housing part 20 has a first housing part-side anti-rotation element 40 that is complementary to the anti-rotation element 38 on the insulation body side and is arranged on an inner side of the first housing part 20, which faces the insulation body 24. As can be seen from the Figures 2 and 4 As can be seen, the anti-rotation element 38 on the insulation body side is designed as a projection, and the first anti-rotation element 40 on the housing part side is designed as a recess that extends through the wall of the first housing part 20 from the inside to the outside. In the assembled state of the connector 10, the anti-rotation element 38 on the insulation body side and the first anti-rotation element 40 on the housing part side interlock to secure the insulation body 24 positively in the first housing part 20.

[0083] Furthermore, the second housing part 22 has a second anti-rotation element 42 on the housing part side, which is designed to be complementary to the first anti-rotation element 40 on the housing part side. In an assembled state of the connector 10, the second anti-rotation element 42 on the housing part side and the first anti-rotation element 40 on the housing part side are designed to engage with each other. In particular, the second anti-rotation element 42 on the housing part side can be formed on an inner side of the second housing part 22, which faces the first housing part 20. Preferably, the second anti-rotation element 42 on the housing part side is designed as a projection that can engage with the first anti-rotation element 40 on the housing part side.Advantageously, with this arrangement the first housing part-side anti-rotation element 40 can be used for the positive locking arrangement of the insulating body 24 in the first housing part 20 and for the positive locking arrangement of the first housing part 20 in the second housing part 22.

[0084] Furthermore, the first housing-side anti-rotation element 40 specifies an orientation around the longitudinal axis of the first housing-side anti-rotation element 40 in which the insulating body 24 can be inserted into the first housing part 20.

[0085] Furthermore, the second housing part 22 is movable along the insertion direction E relative to the first housing part 20, whereby the path of movement along the insertion direction E is limited. The first housing part 20 also has a rebound-mounted locking element 44, which is designed to engage positively in the connector receptacle. The positive engagement of the locking element 44 in the connector receptacle secures the connector 10 to the connector receptacle. Furthermore, moving the second housing part 22 against the insertion direction E and relative to the first housing part 20 releases the engagement of the locking element 44 in the connector receptacle, allowing the connector 10 to be removed from the connector receptacle. The second housing part 22 is arranged externally on the connector 10 so that it can be operated by a user.When the connector 10 is inserted into the connector receptacle, the second housing part 22 is moved relative to the first housing part 20 in the direction of insertion E, thereby releasing the locking element 44 to engage positively in the connector receptacle.

[0086] In particular, the second housing part 44 has a through-opening 46 through which the locking element 44 extends outwards. The through-opening 46 is formed in the insertion section 15 of the first connector section 14. Furthermore, the locking element 44 forms a stop against which the second housing part 22, with its through-opening 46, abuts when the second housing part 22 is moved relative to the first housing part 20 in the direction of insertion E. In other words, the locking element 44 and the through-opening 46 limit the movement of the second housing part 22 in the direction of insertion E relative to the first housing part 20.

[0087] Furthermore, the first housing part 20 has a spring element 48, which is arranged or formed in the housing wall or in the wall of the first housing part 20. The spring element 48 is, in particular, integrally formed with the first housing part 20 and is formed by a recess 50 in the housing wall that at least partially surrounds the spring element 48. The longitudinal direction of the spring element 48 can extend substantially parallel to the insertion direction E, wherein an end of the spring element 48 lying in the insertion direction E is not connected to the first housing part 20, and an end of the spring element 48 lying opposite the insertion direction E is connected to the first housing part 20. Furthermore, the end of the spring element 48 lying in the insertion direction E can have the locking element 44, for example in the form of a lug or a projection, on its outer side facing the second housing part 22.

[0088] It is understood that the first housing part 20 can also have more than one locking element 44 with corresponding spring elements 48, and that the second housing part 22 can accordingly have several through-openings 46. In a preferred embodiment, the first housing part 20 has three locking elements 44, which are uniformly distributed around the circumference Ur on the first housing part 20. Correspondingly, the second housing part 22 has three through-openings 46.

[0089] Furthermore, the second housing part 22 has an external orientation aid 52 in the form of a projection in the area of ​​the insertion section 15, which allows the connector 10 to be inserted into the connector receptacle in a predetermined orientation. The second housing part 22 can also be positively connected to the complementary connector receptacle in the circumferential direction Ur of the second housing part 22, preferably by means of the orientation aid 52. Advantageously, this ensures that an electrical contacting means 54 arranged on the insulating body 24 on the connector side can be correctly electrically connected, and in particular contacted, with a complementary electrical contacting means (not shown) on the connector receptacle side.The multiple connector-side electrical contact means 54 of the insulating body 24 are correctly assigned to their respective complementary connector-side electrical contact means. Furthermore, a torque acting on the elements of the first connector section 14, in particular on the first housing part 20, on the second housing part 22 and / or on the insulating body 24, can be transmitted to or dissipated from the connector receptacle.

[0090] Furthermore, the electrical contact elements 54 on the connector side are designed to electrically connect the conductors or strands of the cable 12 with the corresponding electrical contact elements on the connector receiving side. The electrical contact elements 54 on the connector side can be designed, in particular, as pins and / or sockets. Furthermore, the insulating body 24 is made of a dielectric material to electrically insulate the electrical contact elements 54 on the connector side from other elements of the connector 10. Furthermore, the electrical contact elements 54 on the connector side are each arranged within or on the insulating body 24 in an electrically insulated manner from one another.

[0091] As in Figure 3The connecting element 26 is shown to be rotatably mounted, at least section by section, along the insertion direction E between the first housing part 20 and the second housing part 22. The connecting element 26 can preferably be designed as a hollow body, preferably as a hollow cylindrical body, for example as a nut, which can be force-fitted to the first connecting section 28, which is preferably designed as a thread. The axis of rotation of the connecting element 26 can coincide with the longitudinal axis L1 of the first connector section 14. Furthermore, the connecting element 26 can be arranged between the first housing part 20 and the second housing part 22 such that the connecting element 26 cannot be detached from the first connector section 14 against the insertion direction E.In particular, the connecting element 26 can have on the inside, which faces the first housing part 22, a circumferentially circumferential stop 56 which, in the event of a relative movement of the connecting element 26 with respect to the first housing part 20 against the insertion direction E, abuts a circumferentially circumferentially circumferential stop 58 on the outside of the first housing part 20, which faces the connecting element 26.

[0092] To assemble the connector, the first housing part 20 can be inserted into the connecting element 26 in the direction of insertion E. The second housing part 22 can then be slid onto the first housing part 20 in the opposite direction of insertion E, so that the locking element 44 protrudes through the opening 46. Furthermore, the movement of the second housing part 22 relative to the first housing part 20 in the opposite direction of insertion E can be limited, at least by the connecting element 26. Likewise, the interlocking of the second housing part's anti-rotation element 42 with the first housing part's anti-rotation element 40 can limit the movement of the second housing part 22 relative to the first housing part 20 in the opposite direction of insertion E.Furthermore, the first housing part 20 can have a circumferential shoulder 60 at which the outer diameter of the first housing part 20 decreases abruptly in the direction of insertion E. The shoulder 60 can limit the movement of the second housing part 22 relative to the first housing part 20 against the insertion direction E, by causing the second housing part 22 to abut the shoulder 60 when moving relative to the first housing part 20 against the insertion direction E.

[0093] With reference to the Figures 2 , 3 and 5The following describes the construction of the second connector section 16. The cable locking element 34 can be arranged in the cable routing direction K between the third housing part 32 and the fourth housing part 36. Furthermore, the cable locking element 34 can be designed as a clamping socket that surrounds the cable 12 at least partially along the cable routing direction K. The cable locking element 34 can be arranged between the third housing part 32 and the fourth housing part 36 such that the cable locking element 34 is deformed by the frictional connection of the third housing part 32 with the fourth housing part 36 to secure the position of the cable 12 in the second connector section 16. In particular, the fourth housing part 36 can be designed as a nut that can be screwed onto the third housing part 32.

[0094] Furthermore, the third housing part 32 can be positively connected to the second connecting section 30 of the connecting housing part 18. In particular, the connecting housing part 18 and the third housing part 32 are designed such that the connecting housing part 18 can be slid onto the third housing part 32 in the direction of insertion E in order to positively connect the third housing part 32 to the connecting housing part 18 in the direction of cable routing K. For positive-locking connection of the third housing part 32 with the second connecting section 30, the third housing part 32 has connector-side guide elements 62 at an end lying in the cable routing direction K, which can engage in positive locking with complementary connecting housing-side guide elements 64 of the second connecting section 30 of the connecting housing part 18.In particular, the guide elements 62 on the connector section side can consist of two guide elements which are arranged opposite each other with respect to the longitudinal axis L2 of the second connector section 16 and whose longitudinal direction is essentially parallel to the insertion direction E.

[0095] The connector housing part 18 is essentially hollow-cylindrical in the direction of insertion E and is bounded at one end opposite the insertion direction E by a closing wall 66. Furthermore, the outer surface of the connector housing part 18 is not completely closed and has a recess 68 which, when the connector 10 is connected, allows the cable 12 to be guided to the insulating body 24. Guide elements 64 on the connector housing side are also formed on the recess 68, their longitudinal direction running essentially parallel to the insertion direction E. To connect the connector housing part 18 to the third housing part 32, the connector housing part 18 is pushed onto the third housing part 32 in the insertion direction E such that the guide elements 64 on the connector housing side are moved relative to the guide elements 62 on the connector section side in the insertion direction E.Furthermore, the connecting housing part 18 abuts the third housing part 32, so that the movement of the connecting housing part 18 relative to the third housing part 32 in the insertion direction E is limited. In addition, the recess 68 can extend into the first connecting section 28, so that the external thread of the connecting section 28 is not continuous around its circumference.

[0096] Furthermore, the connector housing part 18 has a connector housing-side alignment element 70, which extends from the first connection section 28 in the direction of insertion E. The first housing part 20 also has a housing-side alignment element 72 that is complementary to the connector housing-side alignment element 70 and engages with the connector housing-side alignment element 70 when the connector 10 is assembled to determine the orientation of the first housing part 20 relative to the connector housing part 18 about the longitudinal axis L1. In particular, the connector housing-side alignment element 70 can consist of at least one projection, wherein in the Figure 2In the illustrated embodiment, three projections are shown, and the housing-side alignment element 72 consists of corresponding recesses that engage in the connection-side housing-side alignment element 70. In other words, the connection-side housing-side alignment element 70 and the housing-side alignment element 72 are interlocked with each other in the assembled state of the connector 10.

[0097] Furthermore, connector 10 has a spacer element 74 (see Figures 2 and 3), which distances the insulating body 24 from the connecting housing part 18 in the direction of insertion E. The spacer element 74 can, in particular, partially enclose the insulating body 24 along the insertion direction E. Preferably, a section of the insulating body 24 along the insertion direction E is not encompassed by the spacer element 74. Furthermore, the anti-rotation element 38 on the insulating body side is not covered by the spacer element 74. The spacer element 74 can also be arranged, at least partially, in the connecting housing part 18 and, in particular, in the first connecting section 28.The spacer element 74 can preferably be formed by two symmetrically, preferably mirror-symmetrically, designed half-shell elements 74a / 74b, which together form an elongated hollow body, preferably a substantially hollow cylindrical body, whose longitudinal axis runs substantially parallel to the insertion direction E and coincides with the longitudinal axis of the insulating body 24.

[0098] Furthermore, it can be provided that the insulating body 24 is arranged at an end of the spacer element 74 lying in the insertion direction E in such a positionally fixed relative to the spacer element 74 that the position of the insulating body 24 relative to the spacer element 74 is unchanging along the insertion direction E. In particular, the insulating body 24 can have an insulating body-side positioning element 76 which can engage with a complementary spacer-side positioning element 78 of the spacer element 74, so that the insulating body 24 and the spacer element 74 are arranged in a form-fitting manner relative to each other along the insertion direction E. As in Figure 2As shown, the positioning element 76 on the insulation body side is designed as a projection extending in the circumferential direction Ur of the insulation body 24 on the outside of the insulation body 24, which faces the spacer element 74. The positioning element 78 on the spacer element side is designed as a groove extending in the circumferential direction Ur on the inside of the spacer element 74, which faces the insulation body 24. Furthermore, it can be provided that the spacer element 74 is arranged at least sectionally along the insertion direction E in the first housing part 20 in the assembled state of the connector 10.

[0099] Referring to Figure 2A method for assembling the connector 10 is described. First, a cable 12 is passed through the fourth housing part 36, through the cable locking element 34, and through the third housing part 32 in the cable routing direction K. A shield for the cable 12 is placed between the cable locking element 34 and the third housing part 36. Furthermore, conductors or strands of the cable 12 are connected to corresponding electrical contact elements 54 on the connector side of the insulating body 24, for example, by soldering. Subsequently, the spacer element 74 is placed on the insulating body 24, and the spacer element 74, together with the insulating body 24, is positioned at an end of the third housing part 32 located in the cable routing direction K.The connecting housing part 18 is then positively connected to the third housing part 32 by means of the second connecting section 30, wherein the spacer element 74 is arranged section by section along the insertion direction E in the connecting housing part 18.

[0100] Furthermore, the first housing part 20 is inserted into the connector 26 in the insertion direction E. Subsequently, the second housing part 22 is pushed onto the first housing part 20 in the opposite direction E, so that the locking element 44 passes through the through-opening 46. The first housing part 20 is then pushed onto the insulating body 24 in the opposite direction E, and the connector 26 is positively connected to the first connection section 28. It may also be possible to align the first housing part 20 with respect to the connection housing part 18 using the alignment element 72 on the housing part side and the alignment element 70 on the connection housing part side. Furthermore, the fourth housing part 36 can be positively connected to the third housing part 32, so that the cable locking element 34 is deformed to fix the position of the cable 12 in the second connector section 16.to secure cable 12 in connector 17.
