Description

Technical area

The present invention relates to an electrical contact element, which is a fitting of contact part housing even at a defined short Entdrilllänge, i. a short untwisted length, of two or more twisted together or to be twisted lines allows. Furthermore, the invention relates to a line arrangement with such a contact element and a manufacturing method for such a line arrangement.

State of the art

For data lines and similar applications in vehicles, twisted pairs are commonly used to generally provide electromagnetic compatibility (EMC), e.g. the crosstalk behavior of the data line, to decrease. Such lines, in particular unshielded-twisted-pair (UTP) lines are used in vehicles u.a. for Ethernet applications and for differential bus systems, such as the CAN bus or FlexRay. For the best possible electrical transmission properties of the line this is twisted over as long a length as possible (twist length) and has only a comparatively short length of a few centimeters at the end of the line in which the lines either untwisted again (Entdrilllänge) or anyway untwisted, so not twisted , are. With a greater twist length or a shorter Entdrilllänge the electrical transmission properties of the data line are improved in particular with respect. Differential signals in the vehicle.

However, if twisted cables are to be provided with connector housing or the like, there is often the problem that with very short Entdrilllängen the correct orientation of the contact parts for orientation of the housing chambers is not given, so that provided with electrical contact parts line ends hardly or not at all in the connector housing can be introduced. An insertion of the contact parts in the connector housing would in this case only possible if the line ends are partially untwisted again.

From the DE 10 2012 213 391 A1 is known in this context that in particular in automotive Ethernet applications too large Entdrilllänge has the consequence that the system-relevant electrical properties of the transmission medium are not met.

To remedy this problem, the cited prior art proposes to fix in the transition region between a twisted and a untwisted part of a line and an electrical plug-in contact attached to each end of the line. The plug contacts are fixed to a rotatable and displaceable turning tool, which is then rotated and moved to twist even the untwisted part of the line. Thereafter, the line ends or the plug contacts are gripped by a gripping element such that the line ends or plug contacts remain unchanged even after the removal of the rotary tool with respect to their orientation. Although this correct alignment of the line ends or plug contacts is achieved, the production of such a line by the necessary tools and grippers continues to be elaborate. In addition, the integration of the proposed tool in existing placement machines designed relatively expensive.

Description of the invention

An object of the invention is therefore to enable using structurally simplest possible means contacting a housed in a housing contact part even with short Entdrilllängen or long Verdrilllängen.

The object is solved by the subject matters of the independent claims. Advantageous developments of the invention are specified in the dependent claims, the description and the accompanying figures.

An inventive electrical contact element has a manufactured from a plastic material contact part housing. Furthermore, the contact element has at least one, preferably undetachably received, electrical contact part, for example in the form of a plug contact having a projecting over the contact part housing insulation displacement section for contacting and fixing an electrical conductor, such as a cable or cable. In this context, "insulation displacement terminal" can be understood as meaning that the conductor together with its insulation is individually inserted, pressed or pressed into the so-called insulation displacement terminal, in which the insulation of the conductor is severed by the sharp electrical contacts in the metal insulation displacement terminal and a as gas-tight, electrical connection is made. Under "unsolvable" can be understood in this context that the contact part and the Kontakteilgehäuse can not be solved without damaging one of the two elements by eg spinning out of each other. This has the consequence that reuse after release is excluded and the contact part is therefore inextricably absorbed in principle. The attachment of the conductor can be done by inserting or impressions by means of an industrial robot or machine. In the insulation displacement section is the conductor is then clamped and is fixed by an undercut between the insulation displacement terminal and an insulating jacket of the conductor. In order to hold the conductor in the insulation displacement section, the contact part housing preferably has a housing base on which the insulation displacement section is arranged, and a housing cover which can be joined thereto and presses or at least holds the conductor in the insulation displacement terminal. The conductor can be insulated with a plastic jacket and exposed only at its ends for electrical contacting, in particular of the contact part.

With the contact element, the previous production process of twisted cables can be fundamentally changed. Thus, it is no longer necessary to first attach the contact part to the conductor and then to twist a plurality of conductors of a line or a cable, resulting in the aforementioned problems in the assembly of connector housing with the contact parts. Rather, it is now possible to perform the twisting of the conductor before attaching the contact parts thereto, since the insulation displacement section is arranged outside the housing and thus exposed or openly accessible. The orientation of the contact parts to each other does not change even after clamping, because they are held together in the contact part housing and are fixed in terms of their orientation or orientation. As a result, after the clamping, the Entdrilllänge or untwisted length can not change, as long as the conductor at its other end also, for example. be held by a twisting machine or otherwise. As a result, a Entdrilllänge or untwisted length of less than 30 mm can be realized. The contact part housing can be fitted relatively easily in a carrier housing.

It has proved to be particularly advantageous for a mechanical manufacturing, if the contact part at least in an initial or provisioning state in which no contacting of the conductor has taken place, a belt section adjacent to the insulation displacement section has, over which the contact part in the initial state together the contact part housing is held on a webbing. In other words, the entire contact element, so the contact part together with the surrounding contact part housing, provided as strapped goods, as is already known in electrical engineering for other components, such as resistors.

In this case, the insulation displacement section can be arranged between the contact part housing and the belt section. The strap portion is in principle a kind of web with respect to the insulation displacement portion and a contact portion of smaller cross-sectional size, so that the belt portion can be separated or severed during processing of the contact element. In this way, the contact element is separated by loosening of the belt and can be further processed.

An advantageous embodiment of the invention provides that the contact part is injected with the plastic material in the contact part housing. As a result, the process step in which the contact part is inserted into the contact part housing before inserting or pressing in the conductor onto the insulation displacement section is eliminated. Because the contact part is e.g. during injection molding, the same as the plastic material, so that it is integrated into the contact part housing.

Alternatively, the Kontakteilgehäuse may have a Vorverrastung and a Endverrastung for engaging with a Gegenverrastung of the contact part. That is, the contact part is movable relative to the contact part housing at least between a pre-locking position and a final detent position. Preferably, the contact member is free of damage but only from the pre-locking position in the final locked position, but not in the reverse direction movable. The pre-lock and the end lock are e.g. formed as engagement grooves or the like in the plastic material and can be formed during injection molding, for example, by slide or the like. As counter locking, the contact part has e.g. an engaging tongue or the like formed integrally with the contact part. The Vorverrastung and the Endverrastung of the contact part housing are far apart in a direction of insertion of the contact part in the contact part housing that the insulation displacement section in a pre-locked position on the Vorverrastung so that the insulation displacement section still protrudes beyond the contact part housing. That is, the contact part is already partly arranged in the contact part housing and can only be replaced by e.g. Spinning the contact part can be removed, but this is usually prohibited by installation instructions from vehicle manufacturers, so that the contact part is in principle insoluble added. If the counter latching of the contact part in the final locked position locks on the end latch, for which purpose the contact part is simply moved further in the insertion direction, the insulation displacement section is received within the contact part housing and thus protected against damage. Locking the contact part in the contact part housing renders overmolding of the contact part obsolete, since the contact part is already firmly connected to the contact part housing when the contact element is provided.

For a good automatability, the movement sequence for reaching the Final locking position from the pre-locking position so that the final detent position can be achieved from the pre-locking position by a translational movement of the contact part relative to the contact part housing.

For efficient production, it has proved to be advantageous if in the contact part housing a plurality of contact parts is received, which are held together in the initial state on the webbing. Thus, the contact elements provided as endless goods can be continuously processed, in which the webbing is used as a kind of magazine e.g. an industrial robot or machines, which optionally have a gripper, is supplied.

The contact element can be provided in a particularly cost-effective manner if the insulation displacement section and the belt section are produced in one piece from a metal material. The contact part may be made of the metal material by punching and possibly bending.

The invention also relates to a line arrangement, with a plurality of electrical contact elements in one or more of the embodiments described above. At the contact elements in each case a number corresponding to one of the plurality, twisted together electrical conductor is attached. For this, the conductors are exposed, e.g. the respective cable or the respective cable is stripped. The line arrangement further has a carrier housing accommodating the plurality of contact elements, which has at least one of the plurality of contact elements corresponding number of contact points for contacting an electrical mating contact or can receive within a mating connector / header. The carrier housing is thus designed multipolar, wherein the contact elements forms the corresponding number of contact points.

• - Zunächst wird ein elektrisches Kontaktelement mit einem aus einem Kunststoffmaterial gefertigten Kontaktteilgehäuse bereitgestellt. In dem Kontaktteilgehäuse ist eine Mehrzahl, also mindestens zwei, von elektrischen Kontaktteilen, z.B. Steckkontakte, vorzugsweise unlösbar aufgenommen. Jedes Kontaktteil weist einen über das Kontaktteilgehäuse hervorstehenden Schneidklemmabschnitt zur Kontaktierung eines elektrischen Leiters auf. Damit kann eine Leitung bzw. ein Leiter auch dann noch an dem Kontaktteil mittels Einlegens, Eindrückens, Einpressens oder dergleichen befestigt werden, wenn das Kontaktteil bereits an dem Kontaktteilgehäuse befestigt bzw. zumindest teilweise darin aufgenommen ist.
• - Zudem wird eine der Mehrzahl von elektrischen Kontaktteilen entsprechende Anzahl von elektrischen Leitern bereitgestellt. Aufgrund der verwendeten Schneidklemmtechnik müssen die elektrischen Leiter nicht freigelegt werden, z.B. durch Abisolieren von Leitungen bzw. Kabeln.
• - Vorzugsweise noch vor dem Befestigen der Leiter an den Kontaktteilen erfolgt ein Verdrillen der elektrischen Leiter miteinander. Hierbei wird so nah bis an das Leiterende verdrillt, dass sich eine möglichst kleine Entdrilllänge bzw. unverdrillte Länge ergibt, sich die Verdrillung also so nah wie möglich an das Leiterende heran erstreckt.
• - Nach dem Verdrillen erfolgt ein Befestigen der miteinander verdrillten elektrischen Leiter an dem Schneidklemmabschnitt des Kontaktteils mittels Crimpen. Durch die gute Zugänglichkeit des über das Kontaktteilgehäuse hervorstehenden Schneidklemmabschnitts lässt sich eine weitere, unerwünschte Entdrillung vermeiden. Nach dem Einlegen, Eindrücken, Einpressen oder dergleichen sind die Leiter ohnehin zueinander fixiert.

Furthermore, the invention also relates to a method for producing a line arrangement. The procedure has the following steps:

• - First, an electrical contact element is provided with a made of a plastic material contact part housing. In the contact part housing is a plurality, so at least two of electrical contact parts, such as plug contacts, preferably undetachably added. Each contact member has an over the contact part housing projecting insulation displacement section for contacting an electrical conductor. Thus, a line or a conductor can still be attached to the contact part by means of insertion, indentation, press-fitting or the like, even if the contact part is already attached to the contact part housing or at least partially received therein.
• In addition, one of the plurality of electrical contact parts corresponding number of electrical conductors is provided. Due to the insulation displacement technology used, the electrical conductors need not be exposed, eg by stripping cables or cables.
• - Preferably before attaching the conductor to the contact parts is a twisting of the electrical conductors together. In this case, it is twisted so close to the end of the conductor that the smallest possible entangling length or untwisted length results, that is, the twist extends as close as possible to the end of the conductor.
• - After twisting a fixing of the twisted together electrical conductors takes place at the insulation displacement portion of the contact member by crimping. Due to the good accessibility of the over the contact part housing protruding insulation displacement section can be a further unwanted untwisting avoided. After inserting, pressing in, pressing in or the like, the conductors are fixed to one another anyway.

For an efficient and cost-effective production of the contact element or the line arrangement, it has proved to be advantageous if the provision of the electrical contact element takes place on a belt. To the webbing, the contact part together with the contact part housing, in which the contact part is preferably injected, is strapped over an adjacent to the insulation displacement section, integrally formed therewith strap portion. Alternatively, a fitting of the strapped contact parts to the first locking level, namely a pre-locking position, in a plug-in contact housing may be useful. This structure would correspond to the contact element. After inserting, pressing in, pressing in or the like, the contact parts are received in the housing by latching a second locking plane, namely a final locked position. Thus, a plurality of strapped contact parts is provided, wherein in each case at least one, but preferably at least two contact parts are integrated in a common contact part housing. The contact parts are electrically isolated from each other by the plastic material of the contact part housing.

If the contact part is not to be embedded in the contact part housing by, for example, encapsulation with plastic material, the contact part may already be engaged with a pre-locking of the contact part housing when the contact element is provided in a pre-locking position. After attaching the twisted conductors to the insulation displacement section, the contact part is then moved relative to the contact part housing and into a final locked position moves, in which it is engaged with a Endverrastung the Kontakteilgehäuses.

For example, To realize a pluggable line arrangement, a single or a plurality of contact elements in a carrier housing with a plurality of contact elements corresponding number of contact points for contacting an electrical mating contact can be introduced. In the carrier housing, the respective contact part housing together with the contact parts received therein, e.g. plugged in and locked in it. Thus, several contact elements can be combined in a carrier housing.

Hereinafter, advantageous embodiments of the invention will be explained with reference to the accompanying drawings. Show it:

• 1 a plurality of contact elements, which are strapped to a webbing via belt sections,
• 2 a line arrangement with conductors twisted together, the respective conductor ends are attached to a respective contact part of a contact element of a first embodiment, and
• 3 a further embodiment of a contact element, wherein a contact part housing has a housing base and a housing cover.

The figures are merely schematic representations and serve only to illustrate the invention. Identical or equivalent elements are consistently provided with the same reference numerals.

In 1 is a plurality of mutually identical electrical contact elements 1 shown in a schematic representation. Each contact element 1 Here, by way of example, two identically designed electrical contact parts 1.1 from an electrically conductive metal material, which in a common contact part housing 1.2 are housed from an electrically insulating plastic material. The contact part 1.1 has one inside the contact part housing 1.2 arranged contact portion 1.3 for example, plug-in contact with a (not shown) electric mating contact and is for this purpose of a front side of the contact part housing 1.2 accessible. To the contact section 1.3 closes in the direction of another end face partially inside and partly outside of the contact part housing 1.2 arranged intermediate section 1.4 on, the contact section 1.3 with a respective insulation displacement section 1.5 combines. The insulation displacement section 1.5 is suitable for attaching an electrical conductor 2 (please refer 2 ) by inserting, indenting or the like and is in the initial state shown here completely outside the contact part housing 1.2 arranged. To the insulation displacement section 1.5 closes in each case, for example, a web-shaped belt section 1.6 on, which is one compared to the intermediate section 1.4 and the insulation displacement portion 1.5 having smaller cross-sectional size. The contact part 1.1 and its sections are made in one piece from the same metal material, but coatings of the respective sections for improving the current conductivity and / or the corrosion behavior are conceivable.

How farther 1 shows, are the contact elements 1 over each contact part 1.1 with a common webbing 3 connected so that the contact elements 1 in an initial state in which at the insulation displacement portion 1.5 not a leader yet 2 is attached, as strapped goods for an at least partially automated manufacturing process. The connection with the webbing 3 takes place via the belt section 1.6 , the integral part of the respective contact part 1.1 is, so every contact element 1 over two belt sections 1.6 on the webbing 3 is held. Because the contact parts 1.1 through the plastic material of the contact part housing 1.2 are injected into this, are also the contact part housing 1.2 over the respective contact part 1.1 on the webbing 3 held. The webbing 3 itself is an endless belt, as it is known from the electrical engineering for taped goods.

In 2 is a conduit arrangement 100 shown in a schematic representation, which is suitable, for example, as an Ethernet line in a vehicle. The line arrangement 100 has the contact element described above 1 , a the contact element 1 receiving carrier housing 4 and two with the contact element 1 connected electrical conductors 2 on. Here is an example only one contact element 1 in the carrier housing 4 picked up so that the carrier housing 4 In principle, a two-pin connector is formed, this by a corresponding number of contact elements 1 could also be multi-pin. To protect the ladder 2 has the carrier housing 4 a strain relief 4.1 on, but alternatively also on the contact part housing 1.2 can be trained.

The electrical conductors 2 are, for example, sheathed cables, which are stripped at the ends of the cable to the conductors 2 for contacting the contact element 1 expose. The ladder 2 are with each other over a twist length L1 twisted and facing adjacent to the contact element 1 or to the insulation displacement sections 1.5 a comparatively short dewing length L2 on which they are not twisted, but run parallel to each other. The the contact element 1 facing free ends of the ladder 2 are by inserting, indenting or the like at the respective insulation displacement section 1.5 of the contact part 1.1 attached, so every conductor 2 at a separate contact part 1.1 of the contact element 1 is attached. It can be seen that the insulation displacement section 1.5 each is housed, namely, for example, by the plastic material of the carrier housing 4 or by foaming with a plastic material. However, it is also conceivable that the respective contact part 1.1 during insertion or indentation is initially in a pre-locking position and is brought into a final locked position after insertion or pressing.

In 3 is another embodiment of the contact element 1 also shown for the line arrangement 100 suitable. The contact element 1 is located in 3A in a pre-assembled and in 3B in a ready assembled state. As in the embodiment described above, the contact element 1 according to the further embodiment, two electrical contact parts 1.1 on, within the contact housing 1.2 are arranged. One difference, however, is that the contact parts 1.1 each adjacent to each other in a housing base 1.21 (in 3 a housing lower shell) are arranged so that in the state shown, the respective insulation displacement section 1.5 accessible from the front side as well as from the open side of the housing. To the case base 1.21 has the contact part housing 1.2 also via a complementary housing cover 1.22 who, as if from a synopsis of 3A and 3B emerges - with the housing base 1.21 For example, can be joined together via a clip connection. In the plastic material of the housing base 1.21 and the housing cover 1.22 is in each case an electromagnetic shield 1.23 embedded, for example injected, which is designed for example in the form of an electrically conductive sheet or a film. The shield 1.23 surrounds the insulation displacement section 1.5 , Furthermore, the contact part 1.1 here also within the contact part housing 1.2 arranged contact portion 1.3 for example, plug-in contact with the (not shown) electric mating contact and is for this purpose of a front side of the contact part housing 1.2 accessible. To the opposite end face of the contact part housing 1.2 also here the insulation displacement section extends 1.5 ,

The line arrangement 100 can as follows from the 1 and 2 explained to be machined. For this purpose, for example, a twisting machine and an industrial robot or machine, preferably with a gripper for the ladder 2 , used.

First, the contact element 1 with the contact part 1.1 and the contact part housing 1.2 with the webbing 3 provided as strapped goods (see 1 ). As stated above, the contact part housing 1.2 at least two contact parts 1.1 on, the unsolvable here in the common contact housing 1.2 are received and an insulation displacement section 1.5 dispose of that over the contact part housing 1.2 protrudes.

In advance, in parallel or afterwards, the two conductors 2 by means of a twisting machine with a predetermined lay length over the twist length L1 twisted together. At this time, the ladder 2 not yet with the respective contact part 1.1 connected. Through the free ends of the ladder 2 These can be used with a very short dewing length L2 twisted together. After twisting, the ends become the conductors 2 eg fixed in the twisting machine, so that they do not unravel again.

Then the twisted conductors become 2 at the respective insulation displacement section 1.5 fastened by inserting, indenting or the like. For this purpose, only a minimum Entdrilllänge is provided, since the insulation displacement section 1.5 outside the contact part housing 1.2 exposed. The insertion, impressions or the like can also be done in by an industrial robot or vending machine, so that both conductors 2 can be fixed in a joint insertion or Eindrückprozess.

To protect the insulation displacement section 1.5 from damage or the like this is either with the plastic material of the contact housing 1.2 or another plastic material encapsulated or foamed and thus housed or wrapped with a winding tape.

Alternatively, in the contact part housing 1.2 but also a Vorverrastung for the contact part 1.1 be formed, at the the contact part 1.1 in a pre-locked position positive and insoluble (because only auspinnbar) can be locked. In the pre-locking position is the insulation displacement section 1.5 , as described above, over the contact part housing 1.2 out, so that the inserting, impressions or the like can be performed. In this embodiment, in the contact part housing 1.2 but also formed a Endverrastung on which the contact part 1.1 in a final locked position positive and insoluble (because only auspinnbar) can be locked. In the final locked position, that of the pre-locking position eg by moving the contact part 1.1 can be achieved in a predefined direction, is the insulation displacement section 1.5 then inside the contact part housing 1.2 arranged and thereby protected, so that an encapsulation, foaming or wrapping the insulation displacement section 1.5 unnecessary.

Finally, the contact element 1 with the ladder attached 2 in the single or multi-pole running carrier housing 4 introduced and locked there or locked. The carrier housing 4 has a number of contact points for contacting an electrical mating contact, that of the plurality of contact elements 1 equivalent.
