Description

Technical Field

[0001] This invention relates to a data connector adapter for data transmission. Such data transmission can be used, for example, between a tractor and a trailer or between a vehicle and onboard machinery (e.g., an agricultural vehicle and agricultural machinery that can be mounted on the agricultural vehicle). The data connector adapter also provides the sealing required for such applications in the automotive field. The data connector adapter includes a plug body having a first plug connection side, a second plug connection side, and, in particular, conductive plug shielding surrounding the first and second plug connection sides, and contact carriers. The first plug connection side includes a first plug contact connection pattern for connecting a first data plug, and the second plug connection side includes a second plug contact connection pattern for connecting a second data plug.

[0002] Within the scope of this invention, the connector pattern is generally applicable to various situations, especially without departing from the subject matter of the invention. The data connector adapter according to the invention should be compatible with different data plugs. The data plug is not part of this invention; it is only described herein as an example to illustrate other features of the invention.

[0003] According to the present invention, the contact carrier of the data plug adapter is disposed between the first plug connection side and the second plug connection side, and carries at least two first contacts and at least two second contacts, arranged such that the first contacts form a first plug contact connection pattern, and the second contacts form a second plug contact connection pattern. Exactly one first contact and exactly one second contact are electrically connected via contact connection segments. Thus, when forwarding data signals in the data plug adapter, the contacts in the data plug adapter will function as conductors in a data cable. In a data cable, data is typically transmitted through conductor pairs, and signal waves are conducted through conductor pairs.

[0004] Line impedance (also known as line resistance or cable impedance) has a decisive impact on the quality of data transmission through conductors. Geometric variations in conductor routing affect line impedance. Such impedance variations interfere with data transmission, particularly reducing the data transmission range and / or the maximum achievable data rate. When data cables are introduced into data plugs, especially in data adapters with different contact connection patterns, as with the function of the data adapter according to the invention, the inevitable geometric variations in conductor routing and the dielectric material (conductor insulation, especially the contact carrier) around the conductors affect impedance variations in the data transmission conductors. Interference repeatedly occurs in data transmission at locations of impedance variation. Background Technology

[0005] For modern applications in the automotive field, particularly those involving the transmission of data from a motor vehicle to external vehicle components (such as trailers, machinery, or other functions) or relying on data exchange with a motor vehicle data network, high data transmission rates, such as 1 Gbit / s, can be achieved. However, in such high-frequency data transmission, interference can limit the possible data rate during transmission, making it impossible or impossible to achieve high data rates over longer transmission paths (especially those still in plug-in form) with the required reliability. Interference in plug-in devices is particularly generated in the form of impedance changes in cables or wires, which can affect the signal wave to be transmitted. According to the prior art, and especially with reference to patent document DE 10 2018 208 532 A1, the impedance of the plug-in device along the plugging direction should be kept constant or nearly constant to minimize such interference. To address this, existing technology proposes an impedance compensation device comprising an inductor section and a capacitor section. The inductor section imparts a variable inductance share to the impedance, while the capacitor section imparts a variable capacitance share. To maintain a constant impedance, the inductance share must be opposite to the capacitance share. This document discloses that the inductor section includes multiple deflectable portions, wherein deflecting the inductor section increases the inductance share and compensates for the capacitance share.

[0006] Patent document DE 10 2018 104 253 B4 discloses an alternative method for influencing the impedance of a connector, wherein the impedance is influenced, in particular, by changing the spacing between the outer conductor and the conductors of the conductor pair or by changing the spacing between the conductors of the conductor pair.

[0007] However, these solutions have proven to be unreliable in practice, especially in more robust environments. External influences, such as vibration, can cause wires to inadvertently move closer together. The resulting impedance changes can negatively impact data transmission. Furthermore, these solutions are structurally complex, increasing manufacturing costs and introducing significant tolerances in cable routing, leading to undesirable impedance fluctuations. Summary of the Invention

[0008] Therefore, the object of the present invention is to provide a data plug adapter for data transmission, which is particularly easy to manufacture in technically robust environments, such as plugs in motor vehicles, can reliably avoid impedance fluctuations, and can reliably achieve high-frequency data transmission outside of motor vehicles.

[0009] This objective is achieved by a data plug-in adapter and a vehicle socket, wherein the data plug-in adapter is hermetically fixed within the socket. For this purpose, it is specifically specified that the first contact is at least partially equipped with a first dielectric constant. The first carrier body is surrounded by electrical insulation, and the second contact is at least partially surrounded by a material having a second dielectric constant. A second, electrically insulating carrier body surrounds the adapter (hereinafter referred to as "data plug adapter"), thereby allowing different carrier bodies in different areas to influence the adapter's impedance in the contact area to varying degrees in a simple manner. In this case, the outer peripheral surfaces of the first and second carrier bodies are at least partially, but preferably completely, abutted against the inner wall surface of the plug shield. It has been shown that the size and shape of the carrier body used as the dielectric are also important, as the effect of the dielectric on waves propagating in the conductor depends particularly on when the electric field of the dielectric is restricted by the plug shield.

[0010] The fact that the outer peripheral surfaces of the first and second carrier bodies are completely in contact with the plug shield means that preferably at least 80%, and particularly preferably at least 90%, of the outer peripheral surfaces are in contact with the inner wall surface of the plug shield. The inner wall surface of the plug shield is typically larger than the outer peripheral surface of the carrier body, so that even when the outer peripheral surface of the carrier body is completely in contact, it is only in contact with a portion of the inner wall surface of the plug shield.

[0011] The term "close contact" refers to direct contact between the carrier body and the inner wall surface of the plug shield. According to the present invention, the first dielectric constant... Second dielectric constant The shape of the outer peripheral surface of the contact carrier and the shape of the inner wall surface of the corresponding plug shield against which the outer peripheral surface of the contact carrier is attached are particularly selected to prevent interference during high-frequency data transmission at the required data rate within the data adapter. Dielectric constant and The parameters can be chosen to be different, or they can be chosen to be the same. Those skilled in the art can determine the specific parameters of the variables empirically through different adapter models and / or through theoretical calculations of the adapter's impedance. Typically, a computational model provides a good starting point for configuration, which can then be optimized empirically until the desired data rate is achieved during data transmission.

[0012] As described above, the transition from the first plug contact connection pattern to the second plug contact connection pattern results in an impedance difference caused by the geometric change of the contacts that conduct data signals (and the contact connection segment between the first and second contacts), which can particularly cause interference at high data rates. The transition between the conductors of the data cable and the contacts in the plug or plug adapter can also cause data transmission interference, especially because the dielectric properties around the conductors that transmit data signals change, resulting in an impedance difference.

[0013] It has been confirmed that the adapter structure described in this invention can minimize impedance variation, and in particular, can optimize the dielectric constant configuration experimentally (especially...). and This includes the shape of the outer peripheral surface of the carrier body or the corresponding plug shield. This allows for reliable data rates in the GBit range, such as 1 GBit / s (gigabits per second). For wave propagation of signal waves in a conductor, the size and shape of the dielectric surrounding the conductor are decisive and have a decisive influence on impedance.

[0014] Geometric variations in the conductors, their relative arrangement, and / or the geometry of the dielectric surrounding them, cause impedance variations with position. The shape and arrangement of the plug shield surrounding the dielectric also significantly influence impedance variations. Based on the structure described according to the invention, those skilled in the art will understand how to optimize the dielectric constant... The shape of the carrier body and plug shield is used to optimize the impedance characteristics of the adapter so that the impedance difference caused by the data plug adapter is minimal, so that no interference occurs when transmitting data at the expected data rate.

[0015] According to a particularly preferred embodiment, the spacing between the first contacts may be specified to be different from the spacing between the second contacts. In this case, the structure proposed according to the invention is particularly reasonable because the change in spacing between the first and second contacts inevitably leads to geometric changes in the structure. These changes also cause impedance changes, which can at least be compensated for by the structure proposed according to the invention, thus preventing interference during data transmission at the required data rate. The contact spacing between the first and second contacts should be understood as the respective first and second contacts being electrically connected to each other via contact connection segments, taking into account the contact spacing between them. The purpose of the adapter is specifically to change this contact spacing, thereby adapting it to various plug contact connection patterns.

[0016] Additionally or alternatively, the diameters of the first and second contacts may also differ, i.e., the diameter of the contact area and / or the diameter of the bearing area of ​​the contacts. The bearing area should be understood as being primarily housed within or surrounded by the carrier body of the contact carrier, and not connected to the plug contacts when the plug is inserted. Correspondingly, the contact area should be understood as the contact segment that connects to the plug contacts when the plug is inserted. In a typical embodiment, as a contact consisting of a pin contact or a lead contact, the contact area protrudes from the carrier body, while the bearing area of ​​the contact is housed within the carrier body. Specifically, the first and other contacts may have different diameters, at least within their contact areas. Smaller diameters in a connection are generally more similar to the geometry in a data cable, resulting in smaller and more easily compensated impedance variations due to geometric changes. On the other hand, smaller diameters are geometrically less stable and are often designed for only a few insertion / removal cycles, typically once during initial installation, and possibly once during maintenance if necessary, rather than during routine use. A larger diameter will result in greater impedance fluctuations, but the geometry allows for several insertion and removal cycles, thus also making it suitable for insertion and removal processes in everyday use.

[0017] According to a preferred embodiment, the first and second contacts are cylindrical in shape, meaning their bases are circular. In this case, the diameter is the diameter of the circular base. However, the invention is not limited to this embodiment. The first and second contacts can also have other basic geometries, such as rectangles or any other basic shape. The base is defined as the surface perpendicular to the insertion direction of the contact (also known as the axial direction of the contact), and thus has a corresponding shape. In this case, the diameter of the contact is defined as the maximum distance between the two edge points of the base. In principle, this also applies to the contact connection section between the first and second contacts.

[0018] According to the present invention, the diameters of the first contact, the second contact, and the contact connecting section can vary multiple times along the direction of the contact housed in the contact carrier.

[0019] Based on the data plug to be used with the data plug adapter, the first contact spacing and the second contact spacing of the first plug contact connection pattern and the second plug contact connection pattern are typically predetermined to match the provided data plug. According to the invention, this can be achieved, in particular, by changing at least one, but preferably several or even all of the following parameters:

[0020] • The diameter of the first and / or second contacts (i.e., within the bearing area of ​​the contacts) in the first carrier body and / or the second carrier body

[0021] • Diameter of the contact connection section

[0022] • The distance between the first contact and the outer peripheral surface of the first carrier body

[0023] • The distance between the second contact and the outer peripheral surface of the second carrier body

[0024] • The distance between the contact connection segment and the outer peripheral surface of the first carrier body and / or the second carrier body

[0025] • The shape of the outer peripheral surface of the first carrier body and / or the second carrier body (i.e., the shape of the inner wall surface of the plug shield in the area where the outer peripheral surface of the first carrier body and / or the second carrier body abuts against the inner wall surface).

[0026] • Dielectric constant of the first carrier body

[0027] • Dielectric constant of the second carrier

[0028] To adjust the impedance so that the impedance in the data connector is equal to the predetermined impedance value.

[0029] It has been confirmed that these parameters significantly affect the impedance characteristics of the adapter, and the coordinated changes in these parameters cause the impedance in the data plug adapter to correspond to a predetermined impedance value, which in particular corresponds to the impedance of the data cable used for data transmission.

[0030] A particularly preferred embodiment of the present invention specifies that at least one element having a third dielectric constant is disposed within the region of the contact connection segment. The third carrier body, wherein the dielectric constant It can be selected as the first dielectric constant. and / or second dielectric constant The same or different. The number of different carrier bodies, especially those directly surrounding the first contact, second contact, and / or contact connection segments (or only indirectly surrounding them, i.e., including the carrier body containing these contacts and directly surrounding them), increases the likelihood of affecting the impedance in the data plug adapter, ultimately resolving smaller local interference areas and minimizing impedance variations, thus enabling reliable data transmission at the desired data rate. Adapters with at least three carrier bodies have proven to perform exceptionally well in practice. Similar to the first and second carrier bodies, the third carrier body can surround the contact segments over a large area, or it can be constructed, for example, as a plate in which the first and second contacts are held and contacted. Preferred variations of the third carrier body will be described in detail below.

[0031] According to the third carrier body provided by the present invention, supplementarily or alternatively, at least one of the following parameters can also be changed:

[0032] • Dielectric constant of the third carrier

[0033] • The shape of the outer surface of the third carrier body

[0034] This is used to adjust the impedance in the plug adapter so that the impedance in the data plug adapter corresponds to a predetermined impedance value.

[0035] This provides greater flexibility in impedance adjustment, especially in localized areas of the contact connection where the conductors transmitting data signals (contacts and contact connections) have geometric variations. Localized approaches to influencing impedance in data plug-in adapters can be particularly useful in these locations.

[0036] According to feasible embodiments, advantageous embodiments of the third carrier body according to the invention may specify that the third carrier body is also disposed in the region between different contact connection segments, wherein each contact connection segment connects one of the first contacts to one of the second contacts. In particular, the third carrier body may be arranged in the region where the spacing between the first contacts and the spacing between the second contacts varies. This may have a highly localized effect on the impedance.

[0037] In other embodiments of the third carrier body (or other carrier body) proposed additionally or alternatively according to the invention, the third carrier body or other carrier body may include a conductive contact shield that is electrically connected to a plug shield. Such a contact shield may be arranged, in particular, between and / or around the contact connection segments. According to the invention, the impedance in the data adapter can also be changed by adjusting the shape of the contact shield and its spacing from the contact connection segments, the first contact, and / or the second contact as one of the parameters (i.e., other parameters), such that the impedance in the data adapter corresponds to a predetermined impedance value.

[0038] An conceivable embodiment of the present invention specifies that one or each of the first contacts, one or each of the second contacts, and the contact connecting segment connecting them are constructed as a single integral contact. This integral contact, as defined herein, is integrally formed of a conductive material and includes the first and second contacts and the contact connecting segment as contact portions according to the present invention. This avoids interfering contact between the individual contact portions during data transmission. Furthermore, such integral contacts can be simply made of conductive material (e.g., low-alloy copper) or other materials, for example, as pin contacts. These integral contacts and each contact portion (first contact, second contact, contact connecting segment) preferably have partially different diameters along their axial direction. For example, the diameter of the contact area of ​​the first contact is approximately 1.3 mm (or between 1.0 mm and 1.5 mm), while the diameter of the bearing area of ​​the first contact is approximately 2.0 mm (or between 1.5 mm and 2.5 mm). This diameter is suitable, for example, for connection to a data plug of a data cable with a conductor cross-sectional area of ​​0.35 mm². 2 up to 0.75 mm 2 Furthermore, Gbit data transmission can reach distances up to 40 meters. Accordingly, for example, the diameter of the contact area of ​​the second contact is approximately 0.5 mm (or between 0.3 mm and 0.75 mm), while the diameter of the bearing area of ​​the second contact is approximately 0.8 mm (or between 0.5 mm and 1.0 mm). This diameter is, for example, suitable for a data plug connected to a data cable with a conductor cross-sectional area of ​​0.12 mm². 2 Up to 0.15 mm 2 Furthermore, Gbit data transmission can reach lengths of approximately 8 to 10 meters. The diameter of the overall contact within the contact connection section preferably corresponds exactly to or approximately to the diameter of the first or second contact within its bearing area. Preferably, the smaller of these diameters can be selected.

[0039] This configuration allows for targeted bending or flexing of the integral contact within the contact connection section to achieve different spacings between the first and second contacts in the mating pattern (short for mating contact connection pattern). The bending or flexing of the contact can be of a suitable shape (in terms of the tooling) so that the initially axially straight contact is transformed into the desired shape in a defined manner (reproducibly) during assembly. A tool of suitable shape can be provided as a separate assembly aid, or integrated, for example, as a guide for the contact into the carrier body of the contact carrier so that bending occurs automatically when the contact is inserted into the carrier body. Pre-bent contacts can also be used.

[0040] In such an embodiment, the first carrier body preferably has a through-hole for the first contact, and the second carrier body preferably has a through-hole for the second contact. Additionally, a third carrier body can be accommodated in the gap between the contact segments. The third carrier body preferably has a groove-shaped recess (as a guide) corresponding to the curvature of the contact segment, in which the curved contact segment can be accommodated (or in the assembled data plug adapter). Furthermore, the first carrier body and / or the second carrier body have retaining rings protruding along their outer peripheral surfaces in the direction of the contact segment. These retaining rings abut against the inner wall surface of the plug shield and surround the contact segment, with the third carrier body accommodated between them. In other words, this results in the retaining rings of both the first and / or second carrier bodies being arranged between the contact segment and the plug shield. The thickness of the retaining rings of the first and / or second carrier bodies can preferably approximately correspond to the spacing between the contact and the plug shield accommodated in the carrier body, such that the contact transmitting the data signal and the plug shield have a corresponding dielectric constant. , The thickness of the dielectric remains approximately the same even within the contact connection area. In many cases, this has proven to be a preferred configuration.

[0041] In this technical solution, all or some of the features described in the previous paragraph are achieved. Particularly advantageous is that the outer peripheral surface of the third carrier body abuts against the defined wall surfaces of the first and second carrier bodies. If the contact shield is housed within the third carrier body, contact with the plug shield can be achieved through wires in the first and / or second carrier bodies—that is, wires passing through and / or surrounding the carrier bodies.

[0042] According to another embodiment of the invention, the plug shield can be constructed as a multi-piece design, wherein multiple portions of the plug shield are electrically connected. For example, the multiple portions of the plug shield can be electrically fixed to each other by mutual insertion, pressing, or locking, or they can be integrally connected. The plug shield can particularly have a socket that forms the base of the plug body, in which other components of the data connector are fixed. Preferred embodiments of such a multi-piece plug shield are further described below.

[0043] In another embodiment, particularly an alternative to the embodiment with an integral contact, the contact connection segment may include a plate as a third carrier body or other carrier body, wherein the first contact and the second contact are in contact and fixed on different sides of the plate by means of their plate connection segment, wherein the plate is provided with a wire track for connecting one of the first contacts to one of the second contacts (i.e., for contact connection or to realize the function of the contact connection segment), and wherein on the plate, a contact shield electrically connected to the plug shield is arranged around the wire track that connects the contacts.

[0044] The first and second contacts are fixed to a plate that serves as a third carrier body or other carrier body. The wire traces attached to the plate are interconnected as components of the contact connection segments. This allows for easy interconnection of many different first and second insert contact connection patterns. Because, in the case of a multi-layer structure, or possibly on an intermediate layer of the plate, the arrangement of the contacts on the plate can be freely adjusted, and electrical connection can be easily achieved through the wire traces on the upper and / or lower sides of the plate. As a third carrier body / other carrier body, the plate also has a third dielectric constant / other dielectric constant. Its impedance characteristics are influenced, at least to a certain extent, by the choice of the substrate material. The contact shielding that can be freely introduced into the substrate can also locally and flexibly affect the impedance characteristics of the data connector.

[0045] According to a preferred embodiment of the present invention, the dielectric constant of the third carrier body (and possibly other carrier bodies) The arrangement and type of the contact shields of the third carrier body (and possibly other carrier bodies) can be parameters such that the impedance in the data plug adapter can be adjusted by changing these parameters so that the impedance in the data plug adapter corresponds to a predetermined impedance value.

[0046] The contact shield in the third carrier body, constructed as a plate, can be formed, for example, by multiple through contacts. In the case of multi-layer plates, these through contacts may also be in the middle layer of the plates, interconnected by wire tracks on one or both sides of the plate. The wire tracks of the contact shield preferably form a closed region surrounding the first and second contacts and the wire tracks connecting them. The arrangement and shape of the wire tracks and / or the through-holes connected thereto of the contact shield can be used as the aforementioned parameters. It has been proven that, according to the rational configuration proposed by the invention, the shape of the wire tracks is chosen such that the spacing between the first and second contacts is as constant as possible, i.e., following a shape that minimizes spacing fluctuations. Another additional or alternative aspect of the shape design of the contact shield may be that the spacing between the first and second contacts and the contact shield approximately corresponds to the spacing between the wire tracks connecting the contacts. These wire tracks can preferably be arranged parallel to each other. This arrangement is particularly easy to achieve if the first contact of the first contact connection pattern and the second contact of the second contact connection pattern rotate relative to each other, for example, based on the position of the contact about the center point or centroid of the connection pattern. A preferred configuration creates a rotation of approximately 90° (including exactly 90°), which allows for a greater spacing between parallel conductor tracks, or enables maximum spacing in a typical arrangement.

[0047] Setting the conductor trace in the middle layer of the board (especially for conductor traces where the first and second contacts are connected as part of a contact connection segment) simulates the structure of conventional conductors in data cables and can be used as another parameter to minimize impedance variations within the contact connection segment area. This also applies to conductor traces with connection segments on both sides of the board (even without an middle layer).

[0048] In principle, it is also conceivable to insert integrally formed and correspondingly curved monolithic contacts into the channels of the plate and fix them therein. In such a design, the above embodiments can also be reasonably combined with each other, wherein the plate can be constructed in particular as other carrier bodies (e.g., a fourth carrier body). At least for continuous monolithic contacts, no wire traces are required on the plate as contact connecting segments. According to the invention, embodiments in which a portion of the contacts are constructed as monolithic contacts (for the purposes of the above definition), while another portion of the contacts are constructed as separate first and second contacts, which are interconnected via contact connecting segments that serve as wire traces on the plate.

[0049] The configuration of this embodiment of the invention can be further specified, wherein the plug shield is constructed as a multi-piece, wherein the first part of the plug body is a socket, and the first and second contacts, contact connection segments, and carrier bodies (i.e., the first carrier body, the second carrier body, and possibly the third and other carrier bodies) are accommodated in the socket, and the socket is preferably also configured as an insertion port for a data plug to be inserted into a data plug adapter. In this embodiment, at least one second part is also provided, which is arranged in the first part and surrounds one of the first or second plug contact connection patterns, i.e., the distance of the second part from the first or second contact is less than the distance from the first part of the plug shield. According to the invention, the first part and the second part or any other part of the plug shield can be integrally made of a single material block. However, it is also conceivable that the first part and the second part or any other part of the plug shield are constructed as portions made of conductive material, and they are arranged in a conductive connection manner in the data plug adapter. For example, the first part of the plug shield can be inserted into and / or pressed into the second part of the plug shield. Fixing the first and second parts in any other way is also included within the scope of this invention.

[0050] According to feasible embodiments, the optimal values ​​of the parameters for impedance optimization, which have been described in detail, can be determined by calculating the impedance in a physical model of the data plug-in adapter. These parameters partially influence each other, so there may be multiple optimal parameter values, wherein the impedance in the data plug-in adapter preferably corresponds to or should correspond to a predetermined impedance value of the data cable. However, determining the parameters in a physical model is complex because the theoretical calculation of impedance needs to take into account the materials and geometric relationships used.

[0051] Therefore, an alternative approach to optimizing parameters is to measure the impedance in the data connector, particularly using a time-domain reflectometry (TDR) device. In a TDR, the transit length and reflection characteristics of electromagnetic waves and signals in a cable or signal conductor are determined. Such methods or similar approaches are known to those skilled in the art. They rely on a pulse generator to produce a series of extremely short signals that are fed into the cable or adapter. The signal amplitude and transit time are compared with the input signal in the measuring device. This comparison allows the location of interference sources. Thus, interference sources are identified, particularly by impedance deviations at the interference source, especially by oscillations.

[0052] Accordingly, to match the impedance of the data adapter to the required impedance value, such as the impedance value of the data cable and / or the data plug connected thereto, the data plug with the data cable can be connected to one or both sides of the data adapter, and the source of interference can be spatially identified by the described measurements. By changing the parameters, the source of interference can be eliminated or at least reduced to a level where the interference does not impede reliable data transmission at the desired data rate.

[0053] It has been confirmed that the data plug adapter of the basic configuration proposed in this invention typically has an impedance of approximately 100Ω, similar to that of a conventional data cable. In this document, an approximate impedance value means that the impedance of the data plug adapter along its length deviates from the average impedance by no more than 5%, and therefore the impedance of the data plug adapter along its length is preferably in the range of 100 ± 5Ω.

[0054] It has been confirmed that, in the preferred embodiment using empirically determined parameters, when measuring parameters with a time-domain reflectometry in the data adapter connected to the data plug, no impedance change or interference that would interfere with data transmission at the desired data rate is observed. For measurement, a data cable can be used to connect the data adapter (preferably on both sides) to the data plug. Interference is understood herein as, in particular, an impedance change of an order of magnitude that would interfere with data transmission at the desired data rate.

[0055] For those skilled in the art, the various orders of magnitude can be determined empirically as appropriate. In this way, especially since the impedance measured along the length of the data plug adapter is nearly the same as the impedance of the cable located outside the adapter, or in other words, no interference affecting data transmission is measured inside the data plug adapter, optimization can be achieved.

[0056] In particular, for the data plug-in adapter proposed according to the present invention, which is preferably applied to the exterior of a motor vehicle, i.e., a motor vehicle data plug-in adapter as a particularly preferred embodiment of the present invention, if the data plug-in adapter prevents moisture penetration through at least one seal, it is equivalent to a particularly preferred embodiment. Preferably, at least two seals are provided, one of which seals the contact surface between the plug shield and the contact carrier (especially the first carrier body and / or the second carrier body), while the other seals the contact surface between the contact and the contact carrier (especially the first carrier body and / or the second carrier body). This reliably prevents moisture from entering the data wiring within the area of ​​the data plug-in adapter according to the present invention. This is especially important in the field of high-frequency data transmission (i.e., especially at transmission rates up to 1 Gbit / s), because if moisture comes into contact with the wires themselves, it will not only cause a short circuit, but also change the impedance in the conductor dielectric system, which may lead to interference in data transmission.

[0057] In a conventional manner, sealing can be achieved using appropriate, resilient seals (such as flat or annular seals, O-ring seals, etc.). These seals adhere tightly to the contact surfaces under pressure, thus creating a seal. Special attention must be paid to cleanliness during assembly, as any foreign matter between the contact surfaces and the seal can cause leakage. Individual components can also be used as seals.

[0058] Therefore, a particularly preferred method for a sealed data connector adapter is that the seal is constructed as a ridge (e.g., in terms of a triangular protrusion) on a more robust component. This ridge is formed on the inner wall surface of the plug shield (or plug body) made of a metallic material and on the outer circumference of the contacts made of a metallic material. These ridges are pressed into the contact surfaces of adjacent materials under contact pressure, namely the first and / or second carrier bodies (and / or other parts of the contact carrier), thereby achieving a seal. Using this type of seal, established standards for motor vehicle exteriors, such as ISO 4091, LV214, USCAR2, SAE, etc., can be met. Furthermore, particularly in the preferred embodiment of the invention, these components, as in the preferred embodiment of the invention, are able to be securely fixed to each other without slippage, especially when connected by insertion.

[0059] In this regard, according to the invention, it is particularly preferred that the ridges do not project symmetrically from the contact surface, but rather form a ramp on one side (especially in the engagement direction) and a shoulder on the other side (especially in the opposite direction of the engagement direction). This facilitates the connection of components and prevents them from easily loosening in the opposite sliding direction. According to a particularly preferred embodiment, the ramps of the two types of ridges (the ridges on the inner wall surface of the plug shield and the ridges on the contacts) of the two seals are in opposite directions. This achieves high strength in the assembled components.

[0060] Another preferred embodiment of the invention may specify that a dedicated connection area is formed on at least one of the first connection side and the second connection side, the dedicated connection area having a plug adapter sleeve that can be inserted into the plug body and correspondingly surrounds the first or second plug contact connection pattern, wherein the inner wall of the plug adapter sleeve is configured to accommodate the corresponding first or second data plug. The plug adapter sleeve may be made of, for example, plastic and can be locked to the plug body. This enables a modular structure on the plug connection side, which can be adapted to a large number of different data plugs by changing the plug adapter sleeve. This is particularly effective because the arrangement of the plug contact connection pattern with the contacts and the plug shield surrounding the contacts corresponds to a fixed structure (e.g., based on a specification or protocol for data plug interoperability), while the outer area of ​​the plug can be disposed of proprietaryly. Using the data plug adapter proposed in this invention, at least one plug connection side is equipped with a modular plug adapter sleeve, which can be universally used for a large number of data plugs.

[0061] A particularly preferred application of the data plug adapter according to the invention is data transmission between a motor vehicle and motor vehicle components (e.g., trailers, machines, or other applications of the motor vehicle or its components), where a data rate higher than 100 Mbit / s, especially high data rates in the Gbit / s range, is required. Data transmission within a motor vehicle, as well as data transmission from the motor vehicle to trailers, machines, or other motor vehicle components connected to a motor vehicle data network, especially externally to the motor vehicle, is increasingly important for various applications. Therefore, a correspondingly robust data plug adapter is needed, which can connect to different data cables on the motor vehicle via a dedicated data plug, and on the other hand, can, when necessary, insert the data plug of the component to be connected to the motor vehicle into the adapter during numerous plug-and-unplug cycles. Furthermore, the adapter must be suitable for accommodating data cables with larger cross-sections and their correspondingly larger data plugs. The cable cross-sections and data plugs used in motor vehicles only allow for a limited range of data transmission at the aforementioned high data rates. Generally, larger cable cross-sections can be used to achieve a wider range of wired high-frequency data transmission. Besides passenger cars, the data plug adapter proposed according to the invention is also particularly suitable for trucks, agricultural vehicles, or engineering vehicles, especially vehicles with machines or functions connected via data communication technology. Therefore, the present invention relates particularly to a vehicle data connector adapter specifically designed for the motor vehicle field, and especially to the sealing requirements of external motor vehicle applications.

[0062] In this regard, the present invention also relates to a vehicle socket for data transmission from a vehicle to a vehicle component, comprising a socket housing having an insertion port for connecting a plug to the vehicle component and an interface for connecting the socket to a vehicle data network or an in-vehicle network, wherein the insertion port can be sealed by a cover hinged to the socket housing. The aforementioned data connector is sealed and fixed within the socket housing, wherein one of the two plug connection sides of the data connector can enter the insertion port, and the other of the two plug connection sides of the data connector can enter the interface.

[0063] The data adapter can be securely fixed in the vehicle socket by means of a suitable (one-piece or multi-piece) seal between the outer periphery of the data adapter and the through-hole of the socket housing, the data adapter being received and fixed within the through-hole. According to a particularly preferred embodiment, the data adapter may have ridges on its circumference (according to the type already described), which are pressed into the plastic socket housing under contact pressure when the data adapter is fixed in the through-hole. A sealing connection can also be established, for example, by injection molding or overmolding.

[0064] To enable power supply in addition to data transmission, or to achieve a single electrical switching process by directly switching on and off working energy, at least one, but preferably multiple, other electrical contacts can be hermetically integrated into the socket housing of the vehicle receptacle in a known manner. Preferably, the other electrical contacts can also make contact in the insertion port and connection interface of the vehicle receptacle. Attached Figure Description

Several functions and advantages of various components of the data plug adapters 100 and 200 according to the present invention have been described above, and those skilled in the art can understand these functions and advantages by referring to the accompanying drawings. These functions and advantages will not be repeated in the following description of the drawings and apply accordingly to all specific embodiments.

[0077] Figure 9 The diagram illustrates and describes a vehicle socket 160 according to the invention and the data adapter 100 housed therein according to a first embodiment. It is self-evident that this is merely illustrative, and all components of the illustrated and described vehicle socket can be combined in the same manner with the data adapter 200 according to a second embodiment.

[0078] Figure 1 The data connector adapter 100 for data transmission shown includes a plug body 101 having a first plug connection side 102 and a second plug connection side 103. The first plug connection side 102 and the second plug connection side 103 are surrounded by a conductive plug shield 104 having a first portion 105 and a second portion 106 in the shape of a socket.

[0079] The first portion 105 of the plug shield forms an insertion port for the data plug on both the first plug connection side 102 and the second plug connection side 103. The first plug connection side 102 shows a first plug contact connection pattern 111 for connecting the first data plug 11, and the second plug connection side 103 shows a second plug contact connection pattern 112 for connecting the second data plug 12.

[0080] The plug body 101 houses a contact carrier 120, which is disposed between the first plug connection side 102 and the second plug connection side 103, and carries at least two first contacts 121 and at least two second contacts 122. These contacts are arranged such that the first contacts 121 form a first plug contact connection pattern 111, and the second contacts 122 form a second plug contact connection pattern 112. Exactly one first contact 121 and exactly one second contact 122 are electrically connected via a contact connection segment 123.

[0081] The first portion 105 of the plug shield also surrounds the first contact 121 on the first plug connection side 102. In contrast, the second contact 122 is arranged to surround the second portion 106 of the plug shield within the first portion 105 of the plug shield. In this first embodiment, the first portion 105 and the second portion 106 of the plug shield are integrally constructed as a common plug shield 104, which also forms the plug body 101.

[0082] In this embodiment, the contact is configured as an integral contact 124, that is, the first contact 121, the second contact 122 and the contact connection section 123 between these contacts 121, 122 are integrally formed of conductive material.

[0083] The first contact 121 is at least partially (with its carrying region 126) subjected to a first dielectric constant. The first carrier body 141 of electrical insulation is surrounded, and the second contact 122 is at least partially (with its bearing region 126) surrounded by a material having a second dielectric constant. The second carrier body 142, which is electrically insulating, surrounds the first carrier body 141 and the second carrier body 142. The outer peripheral surfaces 144 of the first carrier body 141 and the second carrier body 142 are attached to the inner wall surface 145 of the plug shield 104, specifically to the inner wall surfaces 145 of the first part 105 and the second part 106 of the plug shield, respectively.

[0084] The first contact 121 and the second contact 122 protrude from their respective carrier bodies 141 and 142 with their contact areas 125.

[0085] In this embodiment, a third dielectric constant is provided in the region of the contact connection segment 123. The third carrier body 143 is positioned between the contact connection section 123 of the first contact 121 and the second contact 122.

[0086] According to the present invention, the diameters of the first contact 121 and / or the second contact 122 in the first carrier body 141 and / or the second carrier body 142, the diameter of the contact connecting segment 123, the distance between the first contact 121 and the outer peripheral surface 144 of the first carrier body 141, the distance between the second contact 122 and the outer peripheral surface 144 of the second carrier body 142, the distance between the contact connecting segment 123 and the outer peripheral surface 144 of the first carrier body 141 and / or the second carrier body 142, the shape of the outer peripheral surface 144 of the first carrier body 141 and / or the second carrier body 142 (i.e., the shape of the inner wall surface 145 of the plug shield 104 in the area where the outer peripheral surface 144 of the first carrier body 141 and / or the second carrier body 142 abuts against the inner wall surface), and the dielectric constant of the first carrier body 141 are specified. The dielectric constant of the second carrier body 142 The dielectric constant of the third carrier body 143 And / or the shape of the outer surface of the third carrier body 143 is adjusted such that the impedance in the data plug adapter 100 corresponds to a predetermined impedance value, and the data plug adapter 100 transmits data at the required data rate without interference. This has been described in detail above.

[0087] Figure 2 This diagram shows a three-dimensional overview of a data connector adapter 100, including a plug body 101, a first plug connection side 102 for connecting to a first data plug 11, and a second plug connection side 103 for connecting to a second data plug 12. The first data plug 11 connects to a first data cable 13 with a larger cross-section, while the second data plug 12 connects to a second data cable 14 with a smaller cross-section. The plug shield 104 has a connection pattern 111 surrounding the first plug contact. Figure 2 The first part 105 of the plug shield (not visible in the image) and the second part 106 of the plug shield surrounding the second plug contact connection pattern 112.

[0088] A dedicated connection area 113 is constructed on the second plug connection side 103 around the second plug contact connection pattern 112, and the plug adapter sleeve 114 can be inserted into the plug body 101 and around the second plug contact connection pattern 112, wherein the inner wall 115 of the plug adapter sleeve 114 is configured to accommodate the second data plug 12.

[0089] Figure 3The figure shows a partial exploded view of the data connector adapter 100 having the aforementioned components. Referring to this figure, the structure of the contact carrier 120 having a first contact 121, a second contact 122, a first carrier body 141, a second carrier body 142, and a third carrier body 143 is further described below. As shown, the integral contact 124 is selectively bent or flexed in the contact connection section 123 to achieve different spacings between the first contact 121 and the second contact 122.

[0090] The first carrier body 141 has a first through hole 146 for the first contact 121, and the second carrier body 142 has a second through hole 147 for the second contact 122. Additionally, the third carrier body 143 is accommodated in a gap 148 between the first carrier body 141 and the second carrier body 142, and between the contact connecting segments 123. A groove-shaped recess 149 (as a guide portion) of the third carrier body 143 corresponds to the curvature of the contact connecting segment 123 of the integral contact 124; the curved contact connecting segment 123 can be accommodated in this groove-shaped recess 149 or in the assembled data plug-in adapter 100 (see [link]). Figure 1 Additionally, the first carrier body 141 and / or the second carrier body 142 each have retaining rings 150 protruding along their outer peripheral surfaces in the direction of the contact connection section 123. These retaining rings 150 abut against the inner wall surface 145 of the plug shield 104 and surround the contact connection section 123, with the third carrier body 143 accommodating between them. In the assembled state, a common retaining ring 150 is formed.

[0091] The thickness of the retaining ring 150 of the first carrier body 141 and / or the thickness of the retaining ring 150 of the second carrier body 142 preferably corresponds approximately to the spacing between the integral contacts 124 accommodated in the carrier bodies 141 and 142, such that the integral contacts 124 for transmitting data signals and the plug shield 104 have a corresponding dielectric constant. , The thickness of the dielectric is also approximately the same in the area of ​​the contact connection section 123.

[0092] Figure 4 Show in detail again Figure 2 The second plug connection side as described in the text.

[0093] By means similar to the first embodiment described above. Figure 5 A data connector adapter 200 for data transmission is shown, comprising a plug body 201 having a first plug connection side 202 and a second plug connection side 203. The first plug connection side 202 and the second plug connection side 203 are surrounded by a conductive plug shield 204, the plug shield 204 comprising a socket-shaped first portion 205 and a second portion 206 of the plug shield.

[0094] The first portion 205 of the plug shield forms an insertion port for the data plug on both the first plug connection side 202 and the second plug connection side 203. The first plug connection side 202 shows a first plug contact connection pattern 211 for connecting the first data plug 11, and the second plug connection side 203 shows a second plug contact connection pattern 212 for connecting the second data plug 12.

[0095] The plug body 201 houses a contact carrier 220, which is disposed between the first plug connection side 202 and the second plug connection side 203, and carries at least two first contacts 221 and at least two second contacts 222. These contacts are arranged such that the first contacts 221 form a first plug contact connection pattern 211, and the second contacts 222 form a second plug contact connection pattern 212. Exactly one first contact 221 and exactly one second contact 222 are electrically connected via a contact connecting segment 223, which is part of a plate that also serves as the third carrier body 243 in this embodiment.

[0096] In this embodiment, the first plug contact connection pattern 211 and the second plug contact connection pattern 212 are oriented to be rotated 90° relative to each other, so that two contacts 221 can be seen among the two first contacts 221, but only one contact 222 can be seen among the two second contacts 222.

[0097] As in the first embodiment, the first portion 205 of the plug shield also surrounds the first contact 221 on the first plug connection side 202. The second contact 222 is also (additionally) arranged to surround the second portion 206 of the plug shield within the first portion 205. However, in this second embodiment, the first portion 205 and the second portion 206 of the plug shield are constructed as two parts. The first portion 205 and the second portion 206 of the plug shield together form the plug shield 204, wherein these two portions are arranged in a conductively connected manner within the data connector 200. The first portion 205 of the plug shield also forms a socket-shaped plug body 201.

[0098] In the second embodiment, contacts 221 and 222 are configured as multi-piece contacts, wherein both the first contact 221 and the second contact 222 are configured as pin contacts, which are held and in contact within the plate as a third carrier body 243. A contact connection segment 223 for each contact is formed by a wire trajectory constructed on the plate 243, i.e., a conductive connection between each first contact 221 and each second contact 222 (see [reference]). Figure 7 ).

[0099] The first contact 221 is at least partially (with its carrying region 226) subjected to a first dielectric constant. The first carrier body 241 of electrical insulation surrounds the second contact 222, and the second contact 222 is at least partially (with its bearing region 226) surrounded by a second dielectric constant. The second carrier body 242, which is electrically insulating, surrounds the first carrier body 241 and the second carrier body 242. The outer peripheral surfaces 244 of the first carrier body 241 and the second carrier body 242 are attached to the inner wall surface 245 of the plug shield 204, that is, they are attached to the inner wall surfaces 245 of the first part 205 and the second part 206 of the plug shield, respectively.

[0100] The first contact 221 and the second contact 222 protrude from their respective carrier bodies 241 and 242 with their contact areas 225.

[0101] In this embodiment, the third carrier body 243 is configured to have a third dielectric constant. The plate 243 is arranged between the first carrier body 241 and the second carrier body 242. Both the first carrier body 241 and the second carrier body 242 reach the plate 243, wherein a free space 248 is formed between the plate 243 and the first carrier body at the center of the first carrier body 241. In contrast, the second carrier body 242 rests on the plate 243 with its entire end face.

[0102] According to the present invention, the diameters of the first contact 221 and / or the second contact 222 in the first carrier body 241 and / or the second carrier body 242, the diameter of the contact connecting segment 223 (in terms of the dimensions of the wire trajectory 224), the distance between the first contact 221 and the outer peripheral surface 244 of the first carrier body 241, the distance between the second contact 222 and the outer peripheral surface 244 of the second carrier body 242, the distance between the contact connecting segment 223 and the outer peripheral surface 244 of the first carrier body 241 and / or the second carrier body 242, the shape of the outer peripheral surface 244 of the first carrier body 241 and / or the second carrier body 242 (i.e., the shape of the inner wall surface 245 of the plug shield 204 in the area where the outer peripheral surface 244 of the first carrier body 241 and / or the second carrier body 242 abuts against the inner wall surface 245), and the dielectric constant of the first carrier body 241 are specified. The dielectric constant of the second carrier body 242 The dielectric constant of the third carrier body 243 And / or the shape of the outer surface of the third carrier body 243 is adjusted such that the impedance in the data plug adapter 200 corresponds to a predetermined impedance value, and the data plug adapter 200 transmits data at the required data rate without interference. This has been described in detail above.

[0103] Figure 7The figure shows a partial exploded view of a data connector adapter 200 having the aforementioned components. Referring to this figure, the structure of the contact carrier 220, having a first contact 221 and a second contact 222, and a first carrier body 241, a second carrier body 242, and a third carrier body 243, is described in more detail. As shown, the contact carrier 220 does not have the integral contacts as in the first embodiment of the data connector adapter 100. Instead, the first contact 221 and the second contact 222 are configured as pin contacts, which are arranged and contact each other at different intervals on a plate 243. This plate also forms the third carrier body 243.

[0104] The first carrier body 241 has a first through hole 246 for the first contact 221, and the second carrier body 242 has a second through hole 247 for the second contact 222.

[0105] The contact connection section 223 includes a plate that serves as the third carrier body 243. The first contact 221 and the second contact 222 contact and are fixed to the plate on different sides of the plate via their plate connection sections 227. Each plate connection section 227 is configured as a thin pin contact area for the first contact 221 and the second contact 222.

[0106] The plate 243 is provided with a wire track 224 for connecting one of the first contacts 221 and one of the second contacts 222.

[0107] Additionally, a contact shield 230, electrically connected to the plug shield 204, is provided on the plate 243 around the wire trajectory 224 that connects the contacts 221 and 222. This contact shield 230 is formed within the third carrier body 243, which is configured as a plate, by a plurality of through contacts 231 interconnected on one or both sides of the plate via the wire trajectory 232. The wire trajectory 232 of the contact shield forms a closed region around the wire trajectory 224 that connects the first contact 221, the second contact 222, and the contact connection segment 223 that connects them.

[0108] The arrangement and shape of the conductor trace 232 of the contact shield and / or the through holes connected thereto can also be used as the parameters mentioned above. According to Figure 7In the illustrated configuration, the shape of the conductor trajectory 232 is chosen to be approximately arc-shaped, so that the distance from the first contact 221 and the second contact 222 is kept as constant as possible, i.e., following a shape that minimizes spacing fluctuations. Furthermore, the distance between the first contact 221 and the second contact 222 and the contact shield 230 approximately corresponds to the distance between the conductor trajectories 224 that connect the contacts 221 and 222 and are arranged parallel to each other. For this purpose, the first contact 221 of the first contact connection pattern 211 and the second contact 222 of the second contact connection pattern 212 are rotated approximately 90° relative to each other, wherein the positions of the contacts 221 and 222 rotate around the center point or centroid 216 of the connection patterns 211 and 212. In the illustrated embodiment, the center point or centroid 216 corresponds to the center of the circular plate, but the invention is not limited to this configuration.

[0109] As described above, the plug shield 204 is constructed in two parts, including a first part 205 and a second part 206 as separate components. The first part 205 is formed by a plug body 201 in the shape of a socket, while the second part 206 is received within the first part 205, for example, by insertion or pressing, and surrounds the second contact 222 of the second plug contact pattern 212. The first part 205 and the second part 206 of the entire plug shield 204 are electrically connected to each other after assembly.

[0110] In the illustrated embodiment, an electrical connection is established between the plug shield 204 and the contact shield 230 by a conductor in the second carrier body 242. For this purpose, a contact protrusion 233 is provided on the second portion 206 of the plug shield along the direction of the plate 243. This contact protrusion 233 is positioned on the through contact 231 of the contact shield in the assembled data adapter. The contact protrusion 233 extends as a conductor from the edge of the first carrier body 241 facing the plate 243, forming a support flange 234, which has a contact recess.

[0111] Second embodiment Figure 6 and Figure 8 Corresponding to the first embodiment Figure 2 and Figure 4 In the second embodiment, the reference numerals are correspondingly increased by 100. (Refer to the above text) Figure 2 and Figure 4 The description also applies to the second embodiment of the data insertion connection adapter 200.

[0112] In both embodiments, the data plug adapters 100 and 200 prevent moisture penetration through at least two seals 151, 152, 251, and 252. The first seals 151 and 251 seal one or more contact surfaces of the plug shields 104 and 204 (specifically, the first portions 105 and 205 of the plug shields in this embodiment) and the contact carriers 100 and 200 (specifically, the first carrier bodies 141 and 241 in this embodiment), while the second seals 152 and 252 seal one or more contact surfaces of the contacts (specifically, the first contacts 121 and 221 in this embodiment) and the contact carriers 100 and 200 (specifically, the first carrier bodies 141 and 241 in this embodiment). This reliably prevents moisture from entering the data cabling within the data plug adapter 100 and 200 area according to the invention.

[0113] The seals 151, 152, 251, and 252 are constructed as ridges (in terms of triangular protrusions) on the inner wall surfaces of the first portions 105 and 205 of the plug shield and are made of metal. The outer peripheries of the contacts 121 and 221 are also made of metal. These ridges are pressed into the contact surfaces of adjacent materials under contact pressure, specifically into the first carrier bodies 141 and 241 of the contact carriers 120 and 220, thereby achieving a seal.

[0114] Additionally, the outer periphery of the plug bodies 101 and 201 is formed with ridges, which serve as third seals 153 and 253 in the same manner when the data plug adapters 100 and 200 are inserted, for example, into the vehicle socket 160 for data transmission from the vehicle to the vehicle components.

[0115] All seals 151, 152, 251, 252, 153, and 253 are constructed in a ridge-like shape, and each of these ridges has two or more mutually spaced (triangular) convex protrusions 154 and 254.

[0116] Figure 9 The diagram shows a cross-sectional view of a vehicle socket 160 according to the invention, wherein the socket housing 161 has an insertion port 162 for connecting a vehicle component plug and an interface 163 for connecting the socket to a vehicle data network or in-vehicle network, wherein the insertion port 162 can be sealed by a cover 164 hinged to the socket housing. For this purpose, the cover 164 accommodates a seal 165 that abuts against the edge of the insertion port 162 when the cover 164 is closed.

[0117] In one embodiment, the aforementioned data plug adapter 100 is sealed and fixed in the socket housing 161, wherein the first plug connection side 102 of the data plug adapter 100 can enter the insertion port 162, and the second plug connection side 103 of the data plug adapter 100 can enter the connection interface 163.

[0118] A ridge-shaped seal 153, similarly configured to secure the data adapter 100 in the vehicle socket, is located between the outer periphery of the data adapter 100 and the through-hole 166 of the socket housing 161. The data adapter 100 is received and fastened into the through-hole 166. When the data adapter 100 is secured in the through-hole 166, the ridge-shaped seal 153 (according to the type described above) is pressed into the socket housing 161, which is made of plastic, under contact pressure. A sealing connection can also be established, for example, by injection molding or plastic coating.

[0119] In the vehicle socket 160, other electrical contacts 167, but preferably multiple other electrical contacts, are hermetically integrated into the socket housing 161 of the vehicle socket 160 in a known manner. Figure 9 Only one contact is shown in the cross-sectional view. Other electrical contacts 167 are also accessible in the insertion port 162 and the connection port 163 of the vehicle socket.
