Definitions
- the invention relates to an electrical connection line, in particular for the transmission of data at high speed. Above all, a connection cable for transferring data in vehicles.
- connection section is usually bridged with a connection cable consisting of an electrical line and connectors at the ends of the line. It is important to note special features that occur when signals of higher frequency are transmitted. Only when the system of line, connectors and connection technology is adapted to one another can unwanted effects such as increased signal attenuation and crosstalk effects be minimized. For many years, cables have been used which have two wires twisted together. Known in the art as twisted pair cables. The cables are provided with connectors adapted to the transmission frequency and can thus transmit high-frequency signals relatively smoothly.
- the wires can tear out of the connection to the contact element or pull the contact element out of the housing. If, for reasons of caution, twisting too weakly, areas are created along the line in which the two wires are not close together, which leads to a change in the impedance in these areas. A locally occurring impedance change affects the data transmission in a negative sense. After the wires are twisted again, they must still be fixed in position and secured against untwisted because they are no longer held together by the outer sheath. This is generally achieved with adhesive tape or with hoses that contract when exposed to heat. These methods are relatively expensive and in case of a necessary repair, the wires are difficult to access.
- the invention has for its object to provide an electrical connection cable of the type mentioned above, which transmits high-frequency data signals without interference and is easy to manufacture.
- An electrical connection line comprising a cable with an outer jacket, which surrounds, at least in sections, at least two mutually insulated conductors.
- Contact elements which are attached to the ends of the conductors, wherein a holding means, between the end of the outer shell and the contact elements is mounted so that it surrounds the conductors and holds together.
- An electrical connection line wherein the holding means is an elastic hose. Electrical connection line wherein the holding means along the longitudinal axis of the cable is deformable.
- An electrical connection line wherein the size and position of the openings in the elastic tube are selected so that the tube can be gathered along its longitudinal axis.
- An electrical connection line with the openings being slots.
- An electrical connection line with the slots extending substantially in the longitudinal direction of the connecting line, in the wall of the hose.
- connection line with the slots extending at an angle to the longitudinal direction of the connection line in the wall of the hose.
- An electrical connection line wherein the holding means is designed as a spiral spring and the inner diameter of the spiral spring substantially corresponds to the summed diameter of the wires.
- a tube for use as a holding means in an electrical connection line the tube having openings in its wall.
- a method of making an electrical lead comprising the steps of: providing a cable having at least two insulated wires surrounded by an outer sheath. Then remove the outer sheath at the end of the cable so that the wires are accessible in one area. Then postpone a holding agent over the cores and deforming the holding means along the longitudinal direction, the cable in the direction of the outer sheath. Thereafter attaching the contact elements to the ends of the wires and deforming the deformable holding means in the extended position.
- the holding means in this method is an elastic hose or a spiral spring.
- connection cable according to the invention shown in the figures is a twisted pair cable known in the prior art, which is predominantly used for data transmission.
- FIG. 1 shows, a standard twisted-pair cable 10 of two twisted together wires 14, 20.
- the pair of wires is given by an outer sheath 12, which surrounds the wire pair, further stability.
- the wires 14,20 consist of electrical conductors 18, 24, as well as an insulation 16, 22 which isolates the conductors 18,24 against each other.
- a piece (L1) of the outer jacket 12 must be removed to access the individual wires 14, 20.
- a piece of the insulation 16, 22 of the wires 14, 20 is removed to contact the now exposed conductor 18, 20.
- FIG. 2 shows the twisted pair cable 10 after the outer jacket 12 has been removed and the two wires 14, 20 have been unwound.
- the untwisting of the wires 14, 20 is necessary in order to be able to machine them.
- Standard machines in the cable assembly require space around the wire ends of the wires 14, 20.
- the wires 14, 20 must be in be movable in a certain area from the end of the outer shell 12, so that a piece of insulation 16,22 can be removed at the wire ends.
- the conductors 18,24 are then exposed and can be contacted.
- a hose is designed as a holding means and is therefore provided for better understanding with the reference number 30.
- the tube 30 is pushed onto the two aligned wires 14,20.
- the wires 14, 20 are aligned substantially parallel so that they lie as close together as possible after machining.
- the tube 30 is pushed so far until it abuts the outer shell 12.
- the length of the tube 30 does not correspond to the length of the region L1 in which the outer jacket has been removed.
- the tube 30 has in this illustration openings 32 in slot shape, which are located in the tube wall.
- the slots are arranged in this representation in the direction of the longitudinal axis A of the cable 10. In this position, the tube 30 surrounds the wires 14,20 and holds them together elastically.
- the insulation 16,22 on the wires 14,20 is already removed.
- FIG. 4 shows the tube 30 in the shirred state.
- the tube 30 from the in FIG. 3 shown position from the line end, in the direction of the outer jacket 12, are pushed.
- the tube can not slide over the outer shell 12 because its diameter is larger than the inner diameter of the tube (30).
- a tube without openings in the wall would be a further pushing over the wires 14,20, against the outer shell 12, again. This would only work with an extremely thin-walled hose.
- the elastic tube 30 with openings 32 but has the opportunity to gather.
- the tube 30, transverse to the direction A in wrinkles so as to reduce its length over the veins 14,20.
- the tube 30 comprises only a smaller area L2 of the wires 14,20.
- the mobility of the individual wires 14, 20 is made possible and thus a processing of the individual wire ends possible.
- connection lead can be seen after contact parts 40 have been attached to the wire ends of the wires 14, 20 and the elastic hose 30 has been returned to its stretched, original position. Due to the elastic properties of the tube 30, the wires 14, 20 are held together tightly. In this illustration, the tube 30 does not extend over the entire region L1 at which the outer jacket 12 has been removed. However, it can be seen that the tube 30 includes the wires 14, 20 over the entire area between outer jacket 12 and contact parts 40 and holds them together.
- the invention is based on the observation that the transmission properties of the connecting line remain acceptable even when the wires are guided parallel to one another in the region of the connecting line in which the outer jacket has been removed.
- the parallel cores must always be adjacent to each other.
- an elastic holding means which is pushed onto the wires after the outer jacket has been removed.
- the holding means takes over the task of holding the wires together, the outer sheath.
- the holding means is pushed in the direction of the end face of the outer shell. After working the wire ends, the holding means is brought to its original, stretched position where it holds the wires close together.
- an elastic hose is used as holding means.
- the use of an elastic hose ensures that the two wires are always kept close to each other. This ensures a lasting impedance of the line and thus excellent immunity to interference.
- the inner diameter of the elastic tube is smaller than the summed diameter of the wires, the electrical connection line.
- the hose has a wall thickness substantially corresponding to the wall thickness of the outer jacket. This wall thickness provides the necessary strength to hold the wires together. At the same time, the wall thickness is small enough to remain flexible and not mechanically stiffen the wire pair.
- the tube has openings in its wall so that it can be gathered in the direction of the outer jacket and releases the wires for processing.
- an elastic tube with openings in the wall it is possible to allow the tube a certain wall thickness, which leads to two further advantages.
- the wall thickness prevents an adjacent data line from accidentally leaning too close to the connecting line and causing errors due to crosstalk.
- the stable tube wall is pressed by the stable tube wall with sufficient force against the wires to hold them together reliably over the entire length.
- the tube has slots in its wall.
- the arrangement, number and length of the slots determine the properties of the tube when shirring and in its stretched state.
- the optimal setting of these parameters generates a hose that is good at shirring and holds the wires together elastically in the stretched state.
- the elastic tube has a varying wall thickness. Areas with very thin wall thicknesses can behave approximately like openings if the thin areas of the hose wall stretch and thus allow shirring of the hose.
- the wall of the elastic tube bulges along its longitudinal axis, wavy inward and outward.
- the hose can be pushed together like an accordion and pulled apart.
- the wall thickness of the elastic tube along its longitudinal axis alternates ---.
- the thin areas can be easily gathered and the areas with large wall thickness keep the veins together.
- the holding means is designed as a spiral spring, wherein the inner diameter of the spiral spring substantially corresponds to the summed diameter of the wires.
- Another advantage of the structure is evident in the case of a plug-in error during assembly of the line or in a later required repair. Then the veins can simply by shirring the tube be made accessible after the repair, by stretching the tube, pressed together again.

Description
Die Erfindung betrifft eine elektrische Anschlussleitung, insbesondere für die Übertragung von Daten mit hoher Geschwindigkeit. Vor allen Dingen, eine Anschlussleitung zum Übertragen von Daten in Fahrzeugen.The invention relates to an electrical connection line, in particular for the transmission of data at high speed. Above all, a connection cable for transferring data in vehicles.
Zur Übertragung von hochfrequenten Signalen zwischen elektronischen Baugruppen (Knoten) ist es erforderlich die gesamte Verbindungsstrecke zu betrachten. Die Verbindungstrecke wird üblicherweise mit einem Anschlusskabel bestehend aus einer elektrischen Leitung und Steckern an den Enden der Leitung überbrückt. Dabei sind Besonderheiten zu beachten, die auftreten, wenn Signale höherer Frequenz übertragen werden. Nur wenn das System aus Leitung, Steckern und Verbindungstechnik aufeinander angepasst ist, können unerwünschte Effekte, wie erhöhte Signaldämpfung und Übersprecheffekte minimiert werden. Seit vielen Jahren werden Leitungen benutzt, die zwei miteinander verdrillte Adern aufweisen. In der Technik als Twisted-Pair-Leitungen bekannt. Die Leitungen werden mit, auf die Übertragungsfrequenz, angepassten Steckern versehen und können so relativ störungsfrei hochfrequente Signale übertragen.For the transmission of high-frequency signals between electronic assemblies (nodes), it is necessary to consider the entire link. The connection section is usually bridged with a connection cable consisting of an electrical line and connectors at the ends of the line. It is important to note special features that occur when signals of higher frequency are transmitted. Only when the system of line, connectors and connection technology is adapted to one another can unwanted effects such as increased signal attenuation and crosstalk effects be minimized. For many years, cables have been used which have two wires twisted together. Known in the art as twisted pair cables. The cables are provided with connectors adapted to the transmission frequency and can thus transmit high-frequency signals relatively smoothly.
In der heutigen Fahrzeugtechnik ist zu beobachten, dass durch Implementierung von Sicherheitstechnik auf der einen Seite und Multimediaanwendungen auf der anderen Seite, die Datenraten auf den Verbindungsstrecken steigen. Dadurch werden die Anforderungen an die Anschlussleitungen in Fahrzeugen erhöht.In today's vehicle technology, it can be observed that by implementing security technology on the one hand and multimedia applications on the other hand, the data rates on the links are increasing. This increases the requirements for connection cables in vehicles.
Bei der klassischen Kabelkonfektionierung werden Leitungen mit nicht verdrillten Adern verwendet, bei denen die Leitungsenden von der Isolation befreit, und an Kontaktelementen befestigt werden. Für die Energieversorgung von Verbrauchern sowie die Übertragung von Signalen sind die, so angefertigten Leitungen gut geeignet. Die Produktionsanlagen für die Konfektionierung der Fahrzeugleitungen verlangen es, dass die Adern einzeln, in die Bearbeitungsvorrichtung eingebracht werden und einzeln bearbeitet werden. Bei der Konfektionierung von verdrillten Leitungen sind zusätzliche Arbeitsschritte notwendig. Es ist erforderlich den Außenmantel der Leitung auf einer Länge von ca. 50 mm zu entfernen und die Adern zu entdrillen, um sie einzeln bearbeiten zu können. Nachdem die Aderenden bearbeitet und in das Steckergehäuse gesteckt wurden, müssen sie wieder verdrillt werden, damit die Adern dicht beieinander liegen. Das erneute Verdrillen der Adern kann zu mechanischer Spannung an den Adern führen. Bei zu viel Spannung können die Adern aus der Verbindung zum Kontaktelement ausreißen oder das Kontaktelement aus dem Gehäuse ziehen. Wird aus Vorsicht zu schwach verdrillt, entstehen entlang der Leitung Bereiche in denen die beiden Adern nicht dicht aneinander liegen, was zu einer Änderung der Impedanz in diesen Bereichen führt. Eine örtlich auftretende Impedanzänderung beeinflusst die Datenübertragung in negativem Sinn. Nachdem die Adern wieder verdrillt sind, müssen sie noch in der Position fixiert und so gegen entdrillen gesichert werden, da sie nicht mehr durch den Außenmantel zusammengehalten werden. Dieses wird im Allgemeinen durch Klebeband oder mit Schläuchen, die sich bei Wärmeeinwirkung zusammenziehen, erreicht. Diese Verfahren sind relativ aufwendig und im Falle einer notwendigen Reparatur sind die Adern schwer zugänglich.Conventional cable assemblies use cables with non-twisted wires, where the cable ends are removed from the insulation and fastened to contact elements. For the energy supply of consumers as well as the transmission of signals, the lines thus prepared are well suited. The production facilities for the assembly of the vehicle cables require that the wires are introduced individually, in the processing device and processed individually. When assembling twisted cables, additional work steps are necessary. It is necessary to remove the outer sheath of the cable over a length of approx. 50 mm and to unthread the cores in order to process them individually. After the wire ends have been machined and inserted into the connector housing, they must be twisted again so that the wires are close together. The re-twisting of the wires can lead to mechanical tension on the wires. If too much voltage, the wires can tear out of the connection to the contact element or pull the contact element out of the housing. If, for reasons of caution, twisting too weakly, areas are created along the line in which the two wires are not close together, which leads to a change in the impedance in these areas. A locally occurring impedance change affects the data transmission in a negative sense. After the wires are twisted again, they must still be fixed in position and secured against untwisted because they are no longer held together by the outer sheath. This is generally achieved with adhesive tape or with hoses that contract when exposed to heat. These methods are relatively expensive and in case of a necessary repair, the wires are difficult to access.

Der Erfindung liegt die Beobachtung zugrunde, dass die Übertragungseigenschaften der Anschlussleitung auch dann akzeptabel bleiben wenn die Adern in dem Bereich der Anschlussleitung, in dem der Außenmantel entfernt wurde parallel zueinander geführt werden. Allerdings müssen die parallel verlaufenden Adern stets aneinander liegen. Dieses wird durch ein elastisches Haltemittel erreicht, dass auf die Adern aufgeschoben wird, nachdem der Außenmantel entfernt wurde. Das Haltemittel übernimmt die Aufgabe, die Adern zusammenzuhalten, des Außenmantels. Um die Aderenden trotz des Haltemittels bearbeiten zu können, wird das Haltemittel in Richtung der Stirnfläche des Außenmantels geschoben. Nach bearbeiten der Aderenden wird das Haltemittel in seine ursprüngliche, gestreckte Lage gebracht wo es die Adern dicht beieinander hält. Bevorzugt wird als Haltemittel ein elastischer Schlauch verwendet. Durch den Einsatz eines elastischen Schlauchs wird gewährleistet, dass die beiden Adern immer dicht beieinander gehalten werden. Dieses gewährleistet eine gleibleibende Impedanz der Leitung und dadurch eine hervorragende Störunempfindlichkeit.The invention is based on the observation that the transmission properties of the connecting line remain acceptable even when the wires are guided parallel to one another in the region of the connecting line in which the outer jacket has been removed. However, the parallel cores must always be adjacent to each other. This is achieved by an elastic holding means, which is pushed onto the wires after the outer jacket has been removed. The holding means takes over the task of holding the wires together, the outer sheath. In order to process the wire ends despite the holding means, the holding means is pushed in the direction of the end face of the outer shell. After working the wire ends, the holding means is brought to its original, stretched position where it holds the wires close together. Preferably, an elastic hose is used as holding means. The use of an elastic hose ensures that the two wires are always kept close to each other. This ensures a lasting impedance of the line and thus excellent immunity to interference.
Besonders bevorzugt ist, dass der innere Durchmesser des elastischen Schlauchs kleiner ist als der aufsummierte Durchmesser der Adern, der elektrische Anschlussleitung. Dadurch ist die Anschlussleitung unempfindlich gegen relative Bewegung zwischen Stecker und Leitung, da der elastische Schlauch Bewegungen der Adern, relativ zueinander, zulässt, sie jedoch dabei immer aneinanderhält.It is particularly preferred that the inner diameter of the elastic tube is smaller than the summed diameter of the wires, the electrical connection line. As a result, the connecting lead is insensitive to relative movement between the plug and the lead, since the elastic tube permits movements of the leads relative to one another, but always holds them together.
Gemäß einer Ausführungsform weist der Schlauch eine Wandstärke auf die im Wesentlichen der Wandstärke des Außenmantels entspricht. Diese Wandstärke bringt die nötige Kraft auf, um die Adern beieinander zu halten. Gleichzeitig ist die Wandstärke klein genug um flexibel zu bleiben und das Aderpaar nicht mechanisch zu versteifen.According to one embodiment, the hose has a wall thickness substantially corresponding to the wall thickness of the outer jacket. This wall thickness provides the necessary strength to hold the wires together. At the same time, the wall thickness is small enough to remain flexible and not mechanically stiffen the wire pair.
Bevorzugt weist der Schlauch Öffnungen in seiner Wand auf damit er in Richtung des Außenmantels gerafft werden kann und die Adern zur Bearbeitung freigibt. Durch die Verwendung eines elastischen Schlauches mit Öffnungen in der Wand wird es möglich dem Schlauch eine gewisse Wandstärke zuzugestehen, was zu zwei weiteren Vorteilen führt. Zum einen wird durch die Wandstärke verhindert, dass sich eine benachbarte Datenleitung versehentlich zu nahe gegen die Anschlussleitung lehnt und Fehler durch Übersprechen verursacht. Zum anderen wird durch die stabile Schlauchwand mit ausreichender Kraft gegen die Adern gedrückt um sie zuverlässig auf der ganzen Länge zusammenzuhalten.Preferably, the tube has openings in its wall so that it can be gathered in the direction of the outer jacket and releases the wires for processing. By using an elastic tube with openings in the wall, it is possible to allow the tube a certain wall thickness, which leads to two further advantages. On the one hand, the wall thickness prevents an adjacent data line from accidentally leaning too close to the connecting line and causing errors due to crosstalk. On the other hand is pressed by the stable tube wall with sufficient force against the wires to hold them together reliably over the entire length.
Gemäß einer Ausführungsform weist der Schlauch Schlitze in seiner Wand auf. Die Anordnung, Anzahl und Länge der Schlitze bestimmen die Eigenschaften des Schlauches beim Raffen sowie in seinem gestreckten Zustand. Die optimale Einstellung dieser Parameter generiert einen Schlauch, der gut zu Raffen ist und im gestreckten Zustand die Adern elastisch beieinander hält.According to one embodiment, the tube has slots in its wall. The arrangement, number and length of the slots determine the properties of the tube when shirring and in its stretched state. The optimal setting of these parameters generates a hose that is good at shirring and holds the wires together elastically in the stretched state.
Bevorzugt weist der elastische Schlauch eine sich verändernde Wandstärke auf. Bereiche mit sehr dünnen Wandstärken können sich näherungsweise wie Öffnungen verhalten wenn sich die dünnen Bereiche der Schlauchwand dehnen und so ein Raffen des Schlauchs ermöglichen.Preferably, the elastic tube has a varying wall thickness. Areas with very thin wall thicknesses can behave approximately like openings if the thin areas of the hose wall stretch and thus allow shirring of the hose.
Gemäß einer weiteren Ausführungsform wölbt sich die Wand des elastischen Schlauches, entlang seiner Längsachse, wellenförmig nach innen und außen. Dadurch lässt sich der Schlauch ziehharmonikaartig zusammenschieben und auseinanderziehen.According to a further embodiment, the wall of the elastic tube bulges along its longitudinal axis, wavy inward and outward. As a result, the hose can be pushed together like an accordion and pulled apart.
Bevorzugt alterniert die Wandstärke des elastischen Schlauchs entlang seiner Längsachse---. Die dünnen Bereiche lassen sich leicht Raffen und die Bereiche mit großer Wandstärke halten die Adern beieinander.Preferably, the wall thickness of the elastic tube along its longitudinal axis alternates ---. The thin areas can be easily gathered and the areas with large wall thickness keep the veins together.
Gemäß einer weiteren Ausführungsform ist das Haltemittel als Spiralfeder ausgeführt, wobei der innere Durchmesser der Spiralfeder im Wesentlichen dem der aufsummierten Durchmesser der Adern entspricht. Durch die Windungen werden die Adern aneinandergehalten wobei die Feder zum Bearbeiten der Aderenden zusammengeschoben wird.According to a further embodiment, the holding means is designed as a spiral spring, wherein the inner diameter of the spiral spring substantially corresponds to the summed diameter of the wires. By the turns, the wires are held together with the spring for processing the wire ends is pushed together.
Ein weiterer Vorteil des Aufbaus zeigt sich im Falle eines Steckfehlers beim Zusammenbau der Leitung oder bei einer später erforderlichen Reparatur. Dann können die Adern einfach durch Raffen des Schlauches zugänglich gemacht werden und nach der Reparatur, durch Strecken des Schlauchs, wieder aneinandergedrückt werden.Another advantage of the structure is evident in the case of a plug-in error during assembly of the line or in a later required repair. Then the veins can simply by shirring the tube be made accessible after the repair, by stretching the tube, pressed together again.
