Description

[0001] The invention relates to an arrangement of a conductor element having at least two conductors twisted together on a connector for a motor vehicle according to the preamble of claim 1.

[0002] DE 10 2017 101 698 A1 discloses an electrical contact element, comprising a contact part housing made of a plastic material and at least one electrical contact part inseparably contained therein, which has a crimp section projecting beyond the contact part housing for contacting and fastening an electrical conductor.

[0003] Furthermore, a cable arrangement for connecting electrical circuits is known from US 5 100 347 A.

[0004] Furthermore, US 5,151,239 A discloses a method for manufacturing a casing containing a sealant around a ready-to-use, rotatable wire connector.

[0005] The object of the invention is to provide an arrangement of a conductor element having at least two conductors twisted together on a connector for a motor vehicle, so that the signal transmission quality between two components of the motor vehicle can be particularly improved.

[0006] This problem is solved according to the invention by an arrangement of a conductor element having at least two conductors twisted together on a connector for a motor vehicle with the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

[0007] The invention relates to an arrangement of a conductor element comprising at least two twisted conductors on a connector, in particular a connector formed separately from the conductor element, for a motor vehicle. The motor vehicle is preferably a motor vehicle, in particular a passenger car or a commercial vehicle. Alternatively, the motor vehicle is, for example, a passenger bus or a motorcycle. Preferably, the motor vehicle, in particular in its fully manufactured state, comprises the arrangement, that is, in particular at least the conductor element and the connector.

[0008] The respective conductor is, for example, a single wire, particularly within the conductor element. The single wire can also be referred to as a cable core. The conductor element can therefore be a cable consisting of at least two individual wires in the form of the aforementioned cores or conductors. The conductors are made of metal, for example. The respective conductor is, for instance, an insulated or uninsulated wire. Thus, the conductor element is, for example, a twisted pair. The fact that the conductors are twisted together means, in particular, that the conductors are wound around each other in a helical fashion, which can be described as stranding. The conductors can therefore be described as twisted conductors.

[0009] The conductor element is designed, for example, as a data-transmitting, electrical, and / or optical conductor. Thus, the respective conductor is designed, for example, as a data-transmitting, electrical, and / or optical conductor. By arranging the conductor element on the connector, at least two components of the motor vehicle, in particular those designed separately from one another, can be connected or coupled together, especially for data transmission, electrical, and / or optical purposes. Thus, the term "each component" refers in particular to a specific electrical and / or electronic component. For example, at least one of the components is designed as an electronic computing device, such as a control unit. The other component is, for example, a sensor element.In particular, if one or both components are designed as electronic computing devices, the components can thus be connected to each other via the conductors using the connector for data transmission.

[0010] The connector has at least two contact elements, which can be referred to as contact parts, and which are separate from the conductor element, that is, in particular separate from the respective conductor. Each contact element has a connection point through which the respective conductor is connected to the respective contact element, in particular for signal transmission, data transmission, and / or electrical purposes. In other words, the respective conductor and the respective contact element are coupled to each other, preferably directly, via the respective connection point, in particular for signal transmission, data transmission, and / or electrical purposes.

[0011] Furthermore, the connector has at least one housing element, which can be referred to as a connector housing or simply a plug housing. The housing element defines a receiving space at least partially, and in particular at least predominantly or completely. In other words, the housing element forms the receiving space at least partially, which extends in particular within the housing element. The receiving space is understood to be, in particular, the receiving space of the connector. Preferably, the housing element covers the receiving space at least partially, especially on the outside. At least one section of the respective contact element, comprising the respective connection point, is arranged in the receiving space. In other words, the contact elements, together with the connection points, are received at least partially, and in particular at least predominantly or completely, in the receiving space.This means that at least the respective length of the contact elements, in a direction of extension perpendicular to an axial direction of the receiving space, is covered from the outside, in particular at least partially, for example at least predominantly or completely, by the housing element. This means that the contact elements, including the connection points, are at least partially covered by the housing element in the direction of extension. In other words, the housing element surrounds at least the respective length of the respective contact element, in particular in the circumferential direction of the receiving space, at least partially, for example at least predominantly or completely, in particular completely. The direction of extension of the receiving space is, for example, a radial direction. Preferably, the direction of extension is perpendicular to the circumferential direction of the receiving space.

[0012] Furthermore, the connector incorporates injection-molded material that partially fills the receiving space. In other words, the injection-molded material is contained within the receiving space. The term "partially filling the receiving space" refers specifically to the fact that the conductors, contact elements, and the injection-molded material fill the receiving space at least partially, for example, at least predominantly or completely. Since the contact elements, and especially the conductors, are arranged within the receiving space, it is therefore not possible for the injection-molded material to completely fill the receiving space, but only to partially fill it. The injection-molded material extends at least in the direction of the receiving space between the contact elements and the housing element.This means that the injection-molded material is positioned, at least in some areas along its length, between the contact elements and the housing element. In other words, the contact elements are connected to the housing element via the injection-molded material.

[0013] To significantly improve signal transmission quality between at least two vehicle components, the invention provides that at least the lengths of the contact elements and at least partially the conductors are overmolded with the injection-molded material. This means that the lengths of the contact elements, in particular completely, are overmolded with the injection-molded material, and that the conductors are overmolded with the injection-molded material at least partially, in particular at least predominantly or completely, for example, entirely. In other words, the contact elements, including the connection points, and the conductors are at least partially overmolded with the injection-molded material.The phrase "at least the lengths of the contact elements and at least partially the conductors are overmolded with the injection-molded material" means, in particular, that when the receiving space is partially filled with the injection-molded material, especially during an injection molding process, at least the lengths of the contact elements and at least partially the conductors are overmolded with the injection-molded material. Furthermore, at least one coupling element, formed separately from the housing element and separately from the injection-molded material, and surrounded on both sides in the axial direction of the receiving space by the injection-molded material, is arranged in the receiving space. In other words, the coupling element is received in the receiving space, with the injection-molded material adjoining the coupling element at both ends in the axial direction of the receiving space, in particular directly.This means that the coupling element is covered from the outside, and in particular directly, by the housing element in the direction of extension of the receiving space. In other words, the housing element surrounds the coupling element at least partially, for example at least predominantly or completely, and in particular entirely, in the circumferential direction of the receiving space. Furthermore, the conductors are passed through the coupling element in a twisted state, that is to say, in particular, passing through the coupling element while maintaining their twist. In other words, the conductors penetrate the coupling element in a twisted state. This means that the conductors penetrate the coupling element in a state in which the conductors are twisted together. Furthermore, the conductors are coupled to the housing element via the coupling element, bypassing the injection-molded material, and in particular directly. This coupling is understood to mean, in particular, a mechanical coupling.In other words, the conductors are attached to the housing element via the coupling element, particularly directly. This coupling or fastening can be, for example, a positive-locking, force-locking, and / or material-locking coupling or fastening. The characteristic "bypassing the injection molding material" is understood to mean, in particular, avoiding the injection molding material. This means that the coupling of the conductors to the housing element via the coupling element, or the fastening of the conductors to the housing element via the coupling element, occurs without the involvement of the injection molding material.

[0014] The invention is based in particular on the following findings and considerations: In most known cases, connectors can be sealed using conventional single-wire seals or sheath seals. Such seals are generally made of a rubber-like material. However, there are also variants in which connectors, also referred to as plug-in systems, or their components, such as contact elements, are overmolded using single-wire seals. Such a plug-in system therefore has no additional seal, for example, with regard to the injection-molded material. If such connectors are used, which, or whose contact elements, are overmolded due to various process steps, the twisting of the individual wires may not extend to the connector housing or into a seal, as this can negatively affect susceptibility to electromagnetic compatibility.

[0015] In contrast, the aforementioned disadvantages can be avoided by means of the arrangement according to the invention. The core of the invention is, in particular, to arrange the contact element downstream of the connection points in the receiving space, which are entirely overmolded or encased in the injection-molded material. Because the conductors are twisted through the coupling element, the twisting of the conductors can be maintained throughout the coupling element, so that, for example, the conductors are twisted together in the axial direction of the receiving space before, after, and within the coupling element. This means that the coupling element offers the possibility of continuing the twisting of the individual conductors.Furthermore, by coupling the conductors to the housing element via the coupling element, bypassing the injection-molded material, the conductors can be secured within the housing element by means of the coupling element, thus fixing them in place. This allows the twisting of the conductors to be maintained particularly securely. The twisting of the conductors can significantly improve signal quality. Furthermore, the twisting minimizes mechanical stress on the conductors, thereby protecting signal transmission quality. Twisting the conductors may be necessary to ensure signal transmission quality in electrical cables and, for example, to minimize crosstalk between individual conductors. Additionally, overmolding the conductors with the injection-molded material can maintain the twisting particularly securely.Additionally, overmolding or injection molding can create a seal, particularly for the conductors, against capillary action. This ensures that the twisting of the individual wires extends all the way into the connector, especially into its housing or receiving space. These measures can significantly contribute to the functionality, stability, and longevity of the entire system, and in particular, its assembly.

[0016] In a further embodiment, the contact elements are designed to be free of twisting. This means that the contact elements are not twisted together. In other words, the contact elements are not twisted together. Preferably, the contact elements extend at least substantially parallel to each other. In other words, the contact elements are aligned parallel to each other. This ensures an untwisted section of the connector, for example, a specific length of untwisted section, so that this length is not undercut. This significantly improves electromagnetic compatibility. The length is, for example, 30 mm.

[0017] To ensure a particularly secure connection between the coupling element and the housing element, a further embodiment provides for the coupling element to be connected to the housing element at least by a positive locking connection, and in particular directly. This means that the coupling element is connected to the housing element by means of at least one positive locking connection, especially directly. In other words, the coupling element and the housing element are positively locked to each other. This allows the conductors to be fixed particularly securely within the housing element via the coupling element.

[0018] Preferably, the housing element has at least one recess in which the coupling element, in particular a coupling area of ​​the coupling element, is at least partially received to form the positive-locking connection. In other words, the coupling element, in particular its coupling area, is arranged or received at least partially in the recess, thereby creating the positive-locking connection. The recess is, for example, designed as a groove. For example, the recess and the coupling area are designed to correspond to each other. This allows the coupling element to be connected to the housing element in a particularly secure and cost-effective manner, thereby enabling the conductors to be fixed securely in the housing element in a particularly secure and cost-effective manner.

[0019] In a further embodiment, it is provided that the respective conductor is connected to the respective contact element by means of crimping, in particular directly. In other words, the respective conductor and the respective contact element are crimped together, in particular directly. Thus, the respective connection point can be understood to be, in particular, a respective crimp area or crimp point. Through crimping, the respective conductor and the respective contact element can be permanently connected to each other, in particular through plastic deformation, thereby enabling a particularly secure connection, for example, in a particularly cost-effective manner, between the respective conductor and the respective contact element. This allows the respective conductor to be connected to the respective contact element in a particularly durable and reliable manner.

[0020] To significantly improve the transmission quality between components, and in particular to enhance reliability against signal transmission failures, a further embodiment provides that each conductor is movably held within the coupling element in the axial direction relative to the receiving space. This means that the conductor is guided within the coupling element in the axial direction of the receiving space, for example, at least along a defined range of motion. In other words, the conductor is held or supported in the coupling element in a floating manner, at least in the axial direction. This provides strain relief for the conductor, with particular attention paid to ensuring that the twisting pattern is maintained.The mobility of each conductor within the coupling element minimizes mechanical stress on the conductor and / or its connection to the contact element, particularly when a tensile force, especially an unintended one, acts upon it. This prevents damage to the conductor and / or its detachment from the contact element at the connection point, thus significantly increasing reliability against signal interference.

[0021] To further enhance the signal transmission quality between at least two components, the coupling element is further designed to have at least two helically shaped feedthrough channels. This means that each feedthrough channel has a helical or helix-like shape. In other words, each feedthrough channel is shaped according to a helix. The helix, which can also be described as a screw, helical curve, cylindrical spiral, or helical spiral, can be understood here as a curve, particularly with a constant pitch, around the surface of a cylinder, especially an imaginary one. The curve can wind around the surface of the cylinder with a constant pitch. Consequently, the helical shape can be understood as a form corresponding to a helix or a cylindrical spiral.In particular, the feedthrough channels are twisted together. Each conductor is received in its respective feedthrough channel, whereby the conductors are guided through the coupling element, in particular in a twisted fashion, via the feedthrough channels. In other words, each conductor is arranged in its respective feedthrough channel, whereby it penetrates the coupling element, in particular in a twisted fashion, via the respective feedthrough channel. The term "each feedthrough channel" refers specifically to a cavity extending within the coupling element. This means that the respective coupling element has a spiral-shaped internal recess in the form of the respective feedthrough channel.The feedthrough channel, or internal recess, allows the conductor to be guided through the coupling element in a helical shape, particularly to maintain the twist of the conductor or conductor element. This significantly improves signal quality, especially in a very efficient manner. Furthermore, the mechanical stress on the conductors is minimized, thus protecting signal quality. Because the coupling element incorporates feedthrough channels, it effectively creates a tunnel system for the conductors. Therefore, in... Fig. Figure 3 illustrates, in particular, an internal view of the tunnel of the coupling element 16. The ladders can be inserted, in particular pushed, into the tunnel system, or into a tunnel in the form of the coupling element, via assembly processes. This tunnel system ensures the twisting of the ladders. Furthermore, the coupling element can, for example, prevent or ensure that the ladders do not touch each other.

[0022] In a further embodiment, it is provided that a central axis, in particular each central axis, of the helical feedthrough channels extends at least substantially in the axial direction of the coupling element, in particular parallel to the axial direction of the coupling element, and / or in the axial direction of the receiving space, in particular parallel to the axial direction of the receiving space. In other words, the central axis of the respective helical feedthrough channel and the axial direction of the coupling element and / or the receiving space run parallel to each other. This allows the twisting of the conductor to be maintained particularly well. The central axis, which can also be referred to as the helix axis or screw axis, can be understood here as an axis around which the helical shape or the respective feedthrough channel winds. The central axis is thus an axis of the helix.

[0023] In a further embodiment, the feedthrough channels are arranged coaxially. In other words, the central axes of the feedthrough channels are congruent, specifically identical. This means that the feedthrough channels are twisted together, i.e., arranged in a twisted orientation relative to each other. Thus, a multi-start, and in particular at least two-start, helix or helical shape can be provided within the coupling element, whereby, for example, a first start can be formed by a first feedthrough channel, and a second start can be formed by the second feedthrough channel. The feedthrough channels can therefore form a multi-start, and in particular two-start, screw or helix.Because the feedthrough channels are arranged coaxially to each other, the twisting of the conductors can be maintained particularly well within the coupling element and especially within the housing element.

[0024] In a further embodiment, the coupling element is provided with an inlet opening located on a side of the coupling element facing away from the contact elements, through which the respective conductor is inserted into the respective feedthrough channel. This means that the respective conductor can be guided through, or is guided through, the respective inlet opening for placement in the respective feedthrough channel, with the respective inlet opening extending on the side of the coupling element facing away from the contact elements. The side of the coupling element facing away from the contact elements can be referred to as the first side. The respective inlet opening can be referred to as the inlet opening or inlet area. The first side is, for example, an axial end face of the coupling element. The axial direction of the respective inlet opening extends obliquely to the axial direction of the coupling element.In other words, each conductor is inserted into the feedthrough channel at an angle to the axial direction of the coupling element via the respective entry opening. The respective entry opening, i.e., the respective insertion holes in the respective helical structure, can therefore be angled, particularly slightly angled, to reduce mechanical stress on the conductors when inserting them into the coupling element. This minimizes or eliminates mechanical stress that could damage the conductors. Consequently, the protection against conductor damage is significantly increased. The components can thus be connected with exceptional reliability. In particular, this significantly improves signal transmission quality.

[0025] The respective entry opening is, for example, bounded by a surface, in particular an outer surface, of the coupling element located on its first side, with the axial direction of the entry opening extending obliquely to this surface. This means that the surface on the first side forms the entry opening, and the axial direction of the entry opening is oblique to this surface, i.e., not perpendicular to it. In other words, the conductor can be inserted or is inserted through the entry opening obliquely to the surface on the first side that bounds the entry opening.

[0026] In a further embodiment, the coupling element has an outlet opening located on the side of the coupling element facing the contact elements, through which the respective conductor is led out of the respective feedthrough channel. This means that at least a portion of the respective conductor located in the respective feedthrough channel exits the coupling element via the respective outlet opening, i.e., can be removed from the coupling element, with the respective outlet opening extending on the side of the coupling element facing the contact elements. The side of the coupling element facing the contact elements can be referred to as the second side or the outlet side. The respective outlet opening can be referred to as the respective discharge opening or the respective discharge area.Thus, each feedthrough channel can be connected to the surroundings of the coupling element via its respective inlet and outlet openings. In other words, each feedthrough channel opens into the surroundings via its respective inlet and outlet openings. Preferably, the axial direction of each outlet opening extends obliquely to the axial direction of the coupling element. This means that the outlet opening is arranged obliquely, and in particular not perpendicularly, to the axial direction of the coupling element. In other words, the outlet opening is designed to guide the conductor obliquely out of the feedthrough channel relative to the axial direction of the coupling element.The respective exit opening, which can also be referred to as the exit hole, can thus be slightly angled to reduce the mechanical impact on the conductors when they pass through or exit the coupling element. This effectively prevents damage to the conductors, thereby significantly increasing safety against conductor damage. Furthermore, this can also improve signal transmission quality.

[0027] The respective outlet opening is, for example, bounded or formed by a surface arranged on the second side, which can also be referred to as the second surface. In other words, the surface arranged on the second side comprises the respective outlet opening. The second surface is, for example, an axial end face, particularly an outer end face, of the coupling element. Thus, the second side can be an end face of the coupling element. The first side and the second side are preferably different from each other, in particular, sides of the coupling element facing away from or opposite each other. The respective axial direction of the respective outlet opening extends, for example, obliquely to the surface arranged on the second side. This means that the respective outlet opening is arranged obliquely, and in particular not perpendicularly, to the second surface.

[0028] A first further aspect relates to a motor vehicle which has an arrangement according to the first aspect of the invention. Advantages and advantageous embodiments of the invention are to be regarded as advantages and advantageous embodiments of the first further aspect and vice versa.

[0029] A second further aspect relates to a method for manufacturing an arrangement according to the invention and / or for manufacturing a motor vehicle according to the first further aspect. Advantages and advantageous embodiments of the invention and the first further aspect are to be regarded as advantages and advantageous embodiments of the second further aspect and vice versa.

[0030] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own.

[0031] The invention will now be explained in more detail with reference to preferred embodiments and the accompanying drawings. These show: Fig. 1 a schematic partial sectional view of an arrangement according to the invention; and Fig. 2 a schematic front view of a coupling element of an arrangement according to the invention; and Fig. 3 a schematic and perspective transparent representation of a coupling element of an arrangement according to the invention; and Fig. 4 a further schematic and perspective representation of a coupling element according to the invention of an arrangement according to a further embodiment.

[0032] In the figures, identical or functionally equivalent elements are provided with the same reference symbols.

[0033] Fig. Figure 1 shows a schematic partial sectional view of a conductor element 1 attached to a connector 2 for a motor vehicle. The conductor element 1 and the connector 2 are separate components. The conductor element 1 has at least two twisted conductors 3, 4, which can be referred to as single wires or simply as conductors. The conductors 3, 4 are, for example, twisted-pair cable, particularly without a sheath. The conductors 3, 4 are designed to transmit at least one piece of information and / or at least one signal. In this embodiment, the conductors 3, 4 are conductors of a twisted-pair conductor element. For example, each conductor 3, 4 is made of a metal.

[0034] The connector 2 has at least two contact elements 5, 6, each formed separately from the conductor element 1 and / or separately from the conductors 3, 4, and each having a connection point 7, 8, via which the respective conductor 3, 4 is connected, in particular directly, to the respective contact element 5, 6, in particular for signal and / or information transmission. This means that a first contact element 5 has a first connection point 7 via which a first conductor 3 is connected, in particular directly, to the first contact element 5, and that the second contact element 6 has a second connection point 8 via which the second conductor 4 is connected, in particular directly, to the second contact element 6. The term "respective contact element 5, 6" refers in particular to a contact part, which can be described as a contact, in particular an electrical contact.In particular, the respective contact element 5, 6 is formed from an electrical conductor. The respective contact element 5, 6 is designed, for example, as a socket or as a pin, in particular a needle-shaped pin. For example, the respective contact element 5, 6 is made of metal.

[0035] By connecting the conductors 3, 4 via the connection points 7, 8 to the contact elements 5, 6, at least two components of the motor vehicle, particularly electrical and / or electronic components not shown in the figures, can be connected to each other, especially for signal transmission and / or information transmission. For example, one of the components is designed as a conductor-side component, meaning that this component is connected to the connection points 7, 8 via the conductors 3, 4. Furthermore, the other component is designed, for example, as a connector-side or contact-element-side component, meaning that the other component is connected to the connection points 7, 8 via the contact elements 5, 6. For example, the respective connection point 7, 8 is arranged at one end on the respective contact element 5, 6.For example, a third connection point is arranged on the first contact element 5 at one end, and a fourth connection point is arranged on the second contact element 6 at the other end. The other component is connected to the first contact element 5 via the third connection point. Furthermore, the other component is connected to the second contact element 6 via the fourth connection point.

[0036] As in Fig. As can be seen particularly well in Figure 1, the connector 2 has at least one housing element 9, which is formed separately from the contact elements 5, 6. The housing element 9 can be referred to as an automotive housing or automotive enclosure. The housing element is, for example, made of plastic. The housing element 9 at least partially, and in particular at least predominantly or completely, delimits a receiving space 10. Preferably, the housing element 9 completely delimits the receiving space 10 in its circumferential direction, so that, for example, the housing element 9 completely surrounds or encircles the receiving space 10 in its circumferential direction.In the receiving space 10, at least one length region 11, 12 of the respective contact element 5, 6, comprising the respective connection point 7, 8, is arranged, whereby at least the respective length region 11, 12 is covered from the outside by the housing element 9, for example at least partially, in particular at least predominantly or completely, preferably fully, in a direction 14 of the receiving space 10 extending perpendicular to an axial direction 13 of the receiving space 10. Thus, the respective length region 11, 12 is located within the housing element 9. Accordingly, the connection points 7, 8 are arranged within the housing element 9. The direction 14 is, for example, a radial direction of the receiving space 10. The length region 11 is, in this case, a length region of the first contact element 5, the length of which comprises the first connection point 7.Length range 11 can be referred to as the first length range. Length range 12 is, in this case, a length range of the second contact element 6, whose length range includes the second connection point 8. Length range 12 can be referred to as the second length range.

[0037] Furthermore, injection molding material 15 is provided, which is formed separately from the housing element 9. The injection molding material 15 partially fills the receiving space 10. Moreover, the injection molding material 15 extends at least in the direction 14 of the receiving space 10 between the contact elements 5, 6 and the housing element 9. Thus, the injection molding material 15 overmolds at least the contact elements 5, 6. For example, the injection molding material 15 extends, in particular at least in the direction 14, between the contact elements 5, 6. For example, the contact elements 5, 6 are spaced apart from each other in the direction 14 of the receiving space 10. In particular, the contact elements 5, 6 are spaced apart from the housing element 9 in the direction 14.Since the injection molding material 15 is thus arranged between the contact elements 5, 6 and the housing element 9 in the extension direction 14, the covering of the contact elements 5, 6 in the extension direction 14 by the housing element 9 is therefore in particular an indirect covering.

[0038] To significantly improve or enhance the signal transmission quality between the components, particularly in a cost-effective manner, at least the lengths 11, 12 of the contact elements 5, 6 are overmolded by the injection-molded material 15. In other words, the injection-molded material 15 extends in the direction 14 of the receiving space 10 at least between the lengths 11, 12 of the contact elements 5, 6 and the housing element 9. This means that at least the lengths 11, 12, especially the connection points 7, 8, are at least partially, and in particular at least predominantly or completely, for example, entirely, covered by the injection-molded material 15 in the direction 14. Specifically, the injection-molded material 15 extends in the direction 14 between the connection points 7, 8.Furthermore, the conductors 3, 4, particularly at least within the receiving space 10, are overmolded by the injection-molded material 15. This means that the injection-molded material 15, particularly within the receiving space 10, extends at least in the direction 14 between the conductors 3, 4, which are in particular twisted, and the housing element 9. In other words, the conductors 3, 4, particularly within the receiving space 10, are at least partially, in particular at least predominantly or completely, preferably entirely, covered by the injection-molded material 15 in the direction 14 to the outside. Furthermore, at least one coupling element 16, formed separately from the housing element 9 and the injection-molded material 15, is arranged in the receiving space 10, whereby the coupling element 16 is covered from the outside, in particular at least partially, for example at least predominantly or completely, and in particular entirely, by the housing element 9 in the direction 14 of the receiving space 10.The injection-molded material 15 surrounds the coupling element 16, particularly in the receiving space 10, in the axial direction 13 of the receiving space 10, and particularly in an axial direction 17 of the coupling element 16, on both sides. This means that the injection-molded material 15 is arranged on a first side 18 of the coupling element 16 and on a second side 19 of the coupling element 16, which is different from the first side 18. The sides 18 and 19 are different from each other, particularly with respect to the axial direction 17 of the coupling element 16, that is, in particular, they are facing away from each other or opposite each other. The side 18, which can be referred to as the first side 18, is, for example, facing away from the connection points 7 and 8 or from the contact elements 5 and 6, and is thus, for example, a side facing away from the connection points 7 and 8 or from the contact elements 5 and 6.The side 19, which can be referred to as the second side 19, faces, for example, the connection points 7, 8 or the contact elements 5, 6, whereby the second side 19 can be referred to as the side facing the connection points 7, 8 or the contact elements 5, 6. Preferably, the injection-molded material 15, particularly on the first and on the second side 18, 19, and especially directly, rests against the coupling element 16.

[0039] As in Fig. As can be clearly seen, the conductors 3 and 4 are twisted and passed through the coupling element 16. The conductors 3 and 4 are coupled, at least partially, and in particular directly, to the housing element 9 via the coupling element 16, bypassing the injection-molded material 15, particularly mechanically. The coupling element 16 thus forms, for example, an anchor for the conductors 3 and 4. The coupling element 16 allows the conductors 3 and 4 to be securely fixed in the receiving space 10, ensuring that the twisting of the conductors 3 and 4 is maintained with particular reliability. This means that the twisting of the conductors 3 and 4, also known as single-core twisting, can be continued into a connector housing in the form of the housing element 9. This prevents signal interference.

[0040] In addition to coupling the conductors 3, 4 via the coupling element 16 bypassing the injection molding material 15, it can be provided that the coupling element 16 is connected to the housing element 9 through the injection molding material 15, that is, in particular by overmolding with the injection molding material 15.

[0041] Preferably, the coupling element 16 and the housing element 9 or the receiving space 10 are arranged coaxially to each other, whereby, for example, the axial directions 13, 17 extend coaxially to each other. Preferably, the axial directions 13, 17 extend parallel to each other.

[0042] In Fig. Figure 2 shows the coupling element 16 in a schematic front view, which can be referred to as a frontal view. Furthermore, in Fig. 3 The coupling element 16 is shown in a schematic perspective view, in particular in at least a partially transparent representation. In conjunction with Fig. 1 and Fig. Figure 3 clearly shows how the twisting of conductors 3 and 4 can be maintained across the coupling element 16. For example, each conductor 3 or 4 has a first conductor length section through which it is connected to the respective connection point 7 or 8, and thus, in particular, to the respective contact element 5 or 6. This first conductor length section is located in the receiving space 10 and is overmolded by the injection-molded material 15. In this case, the first conductor length section is located on the second side 19 of the coupling element 16. Specifically, the first conductor length section extends outside the coupling element 16. Furthermore, each conductor 3 or 4 has a second conductor length section located inside the coupling element 16.Thus, the respective second conductor length section is located, in particular, within the receiving space 10. The respective second conductor length section adjoins, for example, at least indirectly or directly, such as in the axial direction 13 of the receiving space 10 and / or in the axial direction 17 of the coupling element 16, the respective first conductor length section. Furthermore, the respective conductor 3, 4, for example, has a respective third conductor length section, which is arranged in the receiving space 10 and is thus, in particular, overmolded by the injection-molded material 15. The third conductor length section adjoins, for example, at least indirectly, and in particular directly, such as in the axial direction 13 of the receiving space 10 and / or in the axial direction 17 of the coupling element 16, the respective second conductor length section. In the present case, the respective third conductor length section is arranged on the second side 18 of the coupling element 16.Thus, in particular, the respective third conductor length section is arranged outside the coupling element 16. Preferably, the conductors 3, 4 are twisted together at least in the respective first conductor length section, in the respective second conductor length section and in the respective third conductor length section.

[0043] For example, each conductor 3, 4 has a fourth conductor length section which is arranged outside the receiving space 10. For example, the respective fourth conductor length section connects at least indirectly, and in particular directly, to the respective third conductor length section, for example in the axial direction 13 of the receiving space 10 and / or in the axial direction 17 of the coupling element 16. Preferably, the conductors 3, 4 are twisted together in the respective fourth conductor length section.

[0044] Preferably, the contact elements 5, 6 are free from twisting. Preferably, the contact elements 5, 6 extend parallel to each other, for example in the axial direction 13 of the receiving space 10. Because the contact elements 5, 6 are free from twisting, or because the contact elements 5, 6 extend parallel to each other, at least a longitudinal section 20 of the connector 2, in particular of the receiving space 10, extending in particular in the axial direction 13, can be kept free from twisting, thereby particularly improving or ensuring the signal transmission quality between the components, since, for example, electromagnetic compatibility can be particularly increased.This longitudinal section 20 extends, for example, in the axial direction 13 between a first axial end 21 of the receiving space 10 and the connection points 7, 8. For example, the length of the longitudinal section 20, extending particularly in the axial direction 13, is at least 10 mm, for example at least 20 mm, preferably 30 mm, in particular exactly 30 mm, or at least 30 mm. In particular, the contact elements 5, 6 extend in the axial direction 13 at least from the connection points 7, 8 to the axial end 21. A second longitudinal section 21 of the connector 2, in particular of the receiving space 10, which in particular extends directly in the axial direction 13, for example, to the longitudinal section 20, runs, for example, in the axial direction 13 of the receiving space 10 between the connection points 7, 8 and a second axial end 23 of the receiving space 10 that is different from the first axial end 21.In the present case, the conductors 3 and 4 are twisted together in the second longitudinal section 22. At the second axial end 23, the receiving chamber 10 opens, for example, directly into its surroundings. Thus, an opening, in particular a through-opening, is provided in the enclosure 9 at the second axial end 23, through which the receiving chamber 10 opens into its surroundings. For example, the conductors 3 and 4, in particular twisted form, are passed through this opening so that the conductors 3 and 4 enter the receiving chamber 10 from the surroundings.

[0045] The coupling element 16 can, as is particularly well done in Fig. 2 and Fig. 3. The coupling element has a square, in particular rectangular, cross-section. Alternatively, the cross-section of the coupling element 16 is, for example, round, in particular circular.

[0046] In the exemplary embodiment, the coupling element 16 has two, in particular different from each other, helically shaped feedthrough channels 24, 25, in which the respective conductor 3, 4, in particular its respective second conductor length section, is received, whereby the conductors 3, 4 are guided through the coupling element 16 via the feedthrough channels 24, 25, in particular in a twisted form. This means that the first conductor 3 is guided through the coupling element 16 via a first of the feedthrough channels 24 and the second conductor 4 via a second of the feedthrough channels 25.

[0047] For example, the coupling element 16 has a base body 26, which in this case is hollow, whereby the feedthrough channels 24, 25 are formed as hollow channels in the base body 26. This means that the respective feedthrough channel 24, 25 is formed by a respective cavity extending within the base body 26. Thus, the respective feedthrough channel 24, 25 is, for example, bounded or formed in its respective radial direction by the base body 26, in particular by a respective inner surface of the base body 26. Fig. 3 the coupling element 16 is shown at least partially transparent, making the feedthrough channels 24, 25 running within the coupling element 16 or the base body 26 visible.

[0048] The fact that the feedthrough channels 24, 25 are helically shaped means, in particular, that a helical guide for the conductors 3, 4 is provided or will be provided within the coupling element 16. This allows the respective conductor 3, 4 to be arranged helically within the respective feedthrough channel 24, 25, giving the respective conductor 3, 4 within the respective feedthrough channel 24, 25 a helical shape. Thus, the coupling element 16 contains, for example, a respective internal recess resembling a spiral spring in the form of the respective feedthrough channel 24, 25. Such a structure enables a cable, in the form of the respective conductor 3, 4, passing through the coupling element 16, to be guided in a helical shape within the coupling element 16.This allows the conductors 3 and 4, in particular individual wires or wire pairs, to retain their twist even when passing through the coupling element 16, especially through the base body 26. This significantly improves the signal transmission quality between the components, as untwisting of the conductors 3 and 4 within the coupling element 16 is reliably prevented. Furthermore, damage to the conductors 3 and 4 is avoided, as manual untwisting of the conductors 3 and 4 is no longer necessary.

[0049] The feedthrough channels 24, 25 are preferably designed to allow the twisting of the conductors 3, 4 to continue. As shown in Fig. Figure 3 illustrates that, for example, the conductors 3 and 4 are twisted together by at least half a turn, particularly within the coupling element 16, via the feedthrough channels 24 and 25. However, it is possible that the conductors 3 and 4 are twisted together by at least one turn or by more than one turn, particularly by at least two, via the feedthrough channels 24 and 25. This is shown in Figure 3. Fig. Figure 4 illustrates the coupling element 16 in a schematic perspective view in at least partially transparent representation according to a further embodiment.

[0050] As in Fig. 3 and Fig.As can be seen particularly well in Figure 4, in this embodiment, a central axis 27 of the helical feedthrough channels 24, 25 extends in the axial direction 17 of the coupling element 16. The feedthrough channels 24, 25 are arranged coaxially with each other. This means that the feedthrough channels 24, 25 are twisted relative to each other or intertwined about the central axis 27, which is particularly common. This allows the conductors 3, 4 to also be guided through the coupling element 16 in a twisted configuration. For example, the central axis 27 is arranged coaxially with the axial direction 13 of the receiving space 10. Furthermore, for example, the central axis 27 is arranged coaxially with a central axis of the opening, which is located on the second axial end face.

[0051] Preferably, the respective feedthrough channel 24, 25, that is, in particular, a respective helix according to which the respective feedthrough channel 24, 25 is shaped, revolves around the central axis 27 at least half a turn, for example, at least once, and in particular multiple times. This means that the respective helix or the respective helix shape has at least half a turn, for example, one turn, or preferably several turns. Thus, the pitch of the respective helix or the respective helix shape is, for example, less than or equal to twice the length of the coupling element 16 in its axial direction 17, wherein the pitch is, for example, less than or equal to half the length of the coupling element 16, in particular its base body 26.

[0052] Preferably, the coupling element 16 is made of plastic, that is, of a plastic material. Furthermore, the injection molding material 15 is a plastic material, which is, for example, a different plastic than that of the coupling element 16.

[0053] For example, on the first side 18, a surface 28 of the coupling element 16 is arranged, which surface 28 can be referred to as the first surface. In this case, the first surface 28 is formed by the base body 26. On the second side 19, for example, a surface 29 is arranged, which can be referred to as the second surface 29. This second surface 29 is understood to be, in particular, a second surface 29 of the coupling element 16. The second surface 29 is, for example, formed by the base body 26. The surfaces 28 and 29 are surfaces facing away from each other. In this case, the first surface 28 is arranged at one end of the coupling element 16, in particular the base body 26, in the axial direction 17 of the coupling element 16, and the second surface 29 is arranged at the other end of the coupling element 16, in particular the base body 26, in the axial direction 17.

[0054] The coupling element 16 has two inlet openings 30, 31, which are arranged on the first side 18 and are, for example, bounded or formed by the first surface 28. The respective conductor 3, 4 is inserted into the respective feedthrough channel 24, 25 via the respective inlet opening 30, 31. This means that the first conductor 3 is inserted into the first feedthrough channel 24 via the first of the inlet openings 30, and that the second conductor 4 is inserted into the second feedthrough channel 25 via the second of the inlet openings 31.

[0055] Furthermore, the coupling element 16 has two outlet openings 32, 33, which are arranged on the second side 19. The outlet openings 32, 33 are, for example, bounded or formed by the second surface 29. The respective conductor 3, 4 is led out of the respective feedthrough channel 24, 25 via the respective outlet opening 32, 33. This means that at least a portion of the first conductor 3 received in the first feedthrough channel 24 is led out of the first feedthrough channel 24, and thus at least in particular out of the coupling element 16, via the first of the outlet openings 32, and that at least a portion of the second conductor 4 received in the second feedthrough channel 25 is led out of the second feedthrough channel 25, and thus in particular out of the coupling element 16, via the second of the outlet openings 33.

[0056] For example, it is provided that the axial direction of each inlet opening 30, 31 extends obliquely to the axial direction 17, in particular obliquely to the first surface 28. Alternatively or additionally, it is provided, for example, that the axial direction of each outlet opening 32, 33 extends obliquely to the axial direction 17, in particular obliquely to the second surface 29. This allows for an angled inlet for the respective conductor 3, 4 as well as an angled outlet for the respective conductor 3, 4.

[0057] Overall, the examples show how a system for receiving and continuing twisted single wires, including untwisting stop, can be implemented using this arrangement.
