Definitions
- the invention relates to a connection device and a connection system for a plurality of electrically insulated conductors.
- Terminal strips For the connection of telephone or data lines in telephone exchanges or distribution systems often connecting devices, eg. Terminal strips are provided. These usually have a plurality of guides for first lines ("incoming lines”), a plurality of guides for second lines ("outgoing lines") and contact elements for connecting each of a first with a second line. Preference is given to connection devices which are provided solderless for insulated conductors and based on the Isolation Displacement Contact (IDC) technique.
- the contact elements then preferably each have at least two insulation displacement terminals or, less preferably, two piercing contacts or a cutting terminal and a piercing contact.
- Such devices are known in a variety of embodiments, and many are available on the market. As writings showing such devices are exemplified the EP-A-0 321 151 , the DE-A-2 301 398 , and the DE-A-196 52 422 called.
- a multi-terminal block is known, which is based on the IDC technology and is characterized in that the housing is in one piece.
- the contact elements in addition to the insulation displacement terminals on one side (on the side of the incoming lines) also assigned a cutting edge. This makes it possible to simultaneously cut a conductor to be turned on during the wiring to the required length, without the need for a complex tool.
- An integral strip body is also from the US 4,964,812 known.
- a connection device with a break contact.
- a separating contact consists of two separate contact elements, each with an insulation displacement contact and a resilient end contact, wherein the resilient end contacts of the two contact elements are pressed against each other by the spring force.
- a separate element can be inserted.
- Such can be electrically insulating, whereby the circuit is separable.
- such a separate element can also be embodied, for example, as a print and perform a specific function, for example as overload protection or for removing signals.
- the two contact elements are now formed asymmetrically, so that the distance of the end contacts within a release contact pair is smaller than the distance between adjacent end contacts between isolating contact pairs, whereby the crosstalk is reduced.
- connection devices can be found in US 5,967,826 , where also still a variant is shown, in which the two opposing contact elements are connected by a bridge with each other and thus form a one-piece, U-shaped terminal contact element.
- connection devices with isolating contacts are advantageous for special applications because of their versatile functionality, but are complex to manufacture, consist of many individual parts and require a multi-part housing for geometric reasons.
- the incoming and outgoing line on the same side of the housing and out in the same direction which requires a precise cutting of the lines by a separate knife and can lead to uncontrolled contacts between conductors.
- connection device which ensures a sufficient, standard data transmission security even for high transmission rates in small dimensions. Simple Beschaltiana and low production costs should preferably also be guaranteed.
- the inventive device according to claim 1 has a housing, which is preferably in one piece and in which a plurality of one-piece contact elements extends, each having at least a first and at least one second insulation displacement or piercing contact. Between the first and the second contact of each contact element extends a transitional part.
- the contact elements are arranged in pairs in a conventional manner. According to the invention, the contact elements are now asymmetric, such that the transition part is designed such that the transition parts of the two contact elements of the pairs are closer to one another than the transition parts of adjacent contact elements of different pairs.
- a first advantage is that the insulation displacement or piercing contacts can be arranged equidistantly if required.
- the asymmetric shape ensures that the sections of the contact element which are mainly relevant for the crosstalk behavior - that is, those in which current flows - are nevertheless optimized, ie. between the different pairs as far as possible from each other, are arranged. This allows to meet the requirements of a higher transmission rate without changing dimensions compared to existing connection devices.
- a terminal device may conform to Category 5 according to ISO / IEC 11801 (2002), and this with dimensions as known from an existing Category 3 device. Plugs, sockets, etc. of the existing system can therefore continue to be used for the higher category 5.
- Category 6 connection devices can also be realized with the invention in a small space, with shielding plates preferably being used between the contact element pairs for this purpose.
- the inventive approach makes it possible that the housing is in one piece.
- the production of the housing as a single example. Injection molded part has significant advantages: the manufacturing cost is lower than in multi-part housings.
- the inventive structure allows easy insertion of the contact elements in the one-piece housing. For the assembly of the connection device so only chambers for the contact elements must be provided in the one-piece housing.
- the contact elements can be designed substantially flat and lie in a common plane. This is manufacturing technology particularly favorable: all contact elements or at least groups of contact elements can be punched together from a sheet. After possible deformations, in particular by embossing and / or shearing, they can be used together, held together by a transport strip (web), inserted into the housing.
- the contact elements have at least one substantially flat section, they are, for example, asymmetrical with respect to that plane which connects the two insulation displacement or piercing contacts and runs perpendicular to the flat section.
- the contact elements have at best deviating from the flat configuration, for example, by embossing taught and protruding from the contact element level elements. Such may be formed as tongue-like detents that prevent a longitudinal displacement of the inserted into the housing contact elements. As further elements protruding from the contact element level, reinforcements may be present which increase the mechanical stability at critical points and thereby permit the use of very thin metal sheets. Such reinforcements can serve in particular to ensure the forces of the two forks of an insulation displacement contact.
- the first and second conductors can run in a manner known per se in the region in which they are contacted, substantially parallel to each other and perpendicular to the contact elements. In addition, they are generally guided on opposite sides ("front" and "rear") of the housing when in contact. Although such a configuration is preferred, the invention can also be used for connection devices in which the first and second conductors are not parallel (angled connection device). This can be realized, for example, with bent contact elements.
- each contact element pair i.e., all "left” and “right” contact elements of each pair, respectively
- Each pair then contains a first and a second contact element, wherein the first and the second contact element differ by their shape or orientation.
- the contact elements are not identical according to the invention when the orientation is fixed.
- the first and second contact element of each contact element pair are mirror images of each other.
- first and second contact elements there can be virtually two types of contact elements, "right” and “left” or first and second.
- the first and second contact elements may have an identical shape and differ only by orientation. That is, the second contact elements are then first contact elements, which are, for example, rotated by 180 ° about a longitudinal axis. This applies in particular in the cases in which the contact elements have no protruding from the plane elements (latches, reinforcements, etc.).
- connection devices which are provided for high data transmission rates: they enable a more compact design while complying with the standards (eg category 6).
- the housing may have insertion slots for the conductors in a manner known per se. By inserting insulated conductors into the insertion slots and then pressing them into the contact, the conductors are contacted because the insulation piercing tips or piercing tips of the contacts protrude into these slots.
- the insertion of the conductors - ie the wiring - can be done with the help of a Bescharistechnikmaschinections.
- the housing may have latches for attachment to a mounting channel. These can be symmetrical in such a way that a latching onto the mounting channel in two orientations is possible. In one orientation then lies a first side (for the wiring of the first, here “incoming” lines) and in the other orientation, a second side (for the wiring of the second, here “outgoing” lines) from and is thus easily accessible.
- latches are, for example, from the EP-A-0 994 528 Known to which font is explicitly referenced here, in particular FIG. 1 and their description.
- the contact elements are each assigned two knives. By this or this excess length of a conductor is disconnected as soon as the wiring.
- the fact that the knife is integrated in the connection device, the Beschariswerkmaschine can be designed very simple. Nevertheless, only one single step is necessary for connecting and disconnecting excess lengths. Solutions in which a knife is provided on the wiring tool are in contrast more complicated.
- the knife or at least one knife can be provided as a separate component from the contact element.
- Another advantage of the knife as a separate component is that the choice of material in the components contact element and knife can be optimized. For example, a harder material than the contact element can be selected in the knife.
- Particularly preferred is a structure in which the contacted conductors no longer touch the knife after the Bescliensvorgang. Then the knife does not contribute to the crosstalk behavior, and the capacity of the assembly becomes smaller, which also minimizes losses. Also, the electric potential of the blade is then not relevant, and in principle can exist an electrical connection between the blades of adjacent contact elements.
- the connecting device can even be designed so that a cutting element forms a plurality of knives and may have a single, common, running transversely to the conductor direction cutting edge, which separates excess lengths of several adjacent conductors.
- connection device may have further components.
- a writable wiring cover may be present as a cover.
- the insertion slots can be covered and become, and the pairs of conductors can be labeled according to their function.
- connection device - typically for the side of the first, "incoming" conductors - may be provided with a further cover, which may have a strain relief for a multi-core cable.
- a gel or weather protection grease may be present in a wiring cover and / or a cover or directly in insertion slots for the conductors, which acts as corrosion protection.
- the connection device 1 complies with category 5. It comprises a housing 2 which, in a manner known per se, has a plurality of chambers for contact elements.
- the chambers extend between insertion slots 2.1, which serve as guides for electrically insulated conductors (not shown) to be contacted.
- the contact elements are arranged in pairs. In the illustrated embodiment, the contact element pairs 11 are provided with a numbering 2.2.
- the insertion slots 2.1 are arranged equidistant in the illustrated embodiment, ie, the distances between two insertion slots 2.1 of a pair are equidistant from each other as the distance from an insertion slot to the nearest insertion slot of an adjacent pair.
- the housing Laterally with respect to the contact elements, the housing has pawls 2.3, which serve for fastening in a mounting channel.
- the connecting device has knives 4, 5. Their function will be explained below.
- a labeling cover 6 for second lines (outgoing lines) and a cable cover 7 for first lines (incoming lines) are still visible.
- the cable cover 7 has a strain relief strap 7.1, to which a multiple cables comprehensive, incoming cable can be mechanically guided and / or fixed.
- FIG. 2 the housing 2 is only partially shown. Therefore, one sees the pairwise juxtaposed contact elements 3 and first knife 4 and second knife 5.
- a first knife 4 and a second knife 5 is present.
- the contact elements are substantially flat and define a contact element plane.
- the blades are preferably arranged parallel to this contact element plane and are electrically insulated from the contact elements.
- the design and arrangement of the contact elements in contact element pairs 11 is in the FIGS. 3 and 4 especially visible.
- Each contact element forms a first insulation displacement contact 3.1, a second insulation displacement contact 3.2 and an intermediate transition part 3.3.
- the insulation displacement contacts 3.1, 3.2 can be formed in a conventional manner and provided for the multiple contacting of insulated conductors of a certain diameter or diameter range.
- the insulation displacement contacts have reinforcements 3.4, which have been taught by embossing and which ensure mechanical stability and sufficient clamping forces even when using very thin sheet metal.
- the also visible (here as rectangular elements) imprints in the narrowest point of the insulation displacement terminal serve to adjust the width of the contact slot, regardless of the punching tool.
- the contact elements In the region of the transition part 3.3, the contact elements have scissors-shaped detent pawls 3.5, which engage after insertion of the contact elements in the chambers of the housing 2 with a locking cam 2.4 of the housing and prevent displacement of the contact elements in the direction of their longitudinal / longitudinal axis. When “shearing" the material is not completely removed unlike punching; here we simultaneously bent the latch. Two pawls 3.5 are drawn per contact element. If the chambers are asymmetrical and shaped so that they form a stop for the locking elements when inserted, also a detent pawl per catch element is sufficient.
- the contact elements are asymmetrically shaped in such a way that even with equidistant arrangement of the insulation displacement contacts, the transitional parts 3.3 of the two contact elements of a contact element pair closer to each other than the transition part of a contact element of an adjacent pair.
- This in contrast to the known prior art, according to which the contact elements are each symmetrical (the plane of symmetry is in the longitudinal direction, the contact element plane perpendicular plane).
- the first and the second contact element 3 of each pair of contact elements not only differ in their orientation, but differ geometrically.
- the first and second contact elements are mirror images of each other.
- FIG. 6 illustrates how the use of substantially flat contact elements enables a particularly simple production of the device according to the invention.
- the housing 1 is preferably made as a single injection molded part.
- a precursor is produced by punching and subsequent embossing from a sheet metal, for example a steel sheet, which has a multiplicity of contact elements / blades, which are provided by webs 13, 14 and 15 are held together.
- the precursors are optionally cut to a length which corresponds to the length of the connection device and then in the orientation according to FIG. 6 pressed into the designated chambers of the housing. Then the bridges are broken off. By wedging the knives in the plastic housing (by barbs), the knives are held in the housing.
- the contact elements have - for example, in contrast to the contact elements according to EP 0 994 528 - No sections which are bent by more than 90 ° relative to the contact element level. Only this circumstance makes it possible that the contact elements (and also the knives) can be produced only by punching and embossing.
- FIG. 7 shows two connection devices, in which the covers 6, 7 are mounted, in a mounting channel 21.
- the pawls 2.3 engage in openings provided for this purpose 21.1 on side walls of the cable channel, whereby the connecting devices are attached.
- FIG. 8 the housing 31 of an alternative embodiment of the inventive connecting device is drawn.
- This connection device differs from that described above in that a shield is present between the contact element pairs (not shown).
- This is formed by shielding walls 32. 1, which are present on a shielding element 32.
- special insertion slots 31.1 are provided between contact element pairs in the housing.
- the shielding walls 32.1 shield contact elements of adjacent pairs, in particular in the region of the insulation displacement contacts, where the contact elements are spatially closer to each other than in the region of the transitional parts.
- the shielding walls 32.1 are all electrically connected to each other.
- the shielding element 32 is grounded as a whole via fork contacts 32.2, which contact side walls of the mounting channel 21 in the installed state of the device.

- FIG. 9 a pair of contact elements of an embodiment is shown in which the incoming and outgoing conductors are at an angle to each other. Although a machining step is more necessary for the production of these angled contact elements 41 than in the above embodiments and the housing may not be integral, the inventive idea is realized in this embodiment as well.
- the transitional parts 41.3 of the two contact elements of a pair are here due to the asymmetric configuration (with respect to a plane which connects the insulation displacement contacts together and perpendicular to the flat sections) closer together than the distance to the adjacent contact element of another pair.
- FIGS. 10 and 11 show a plug of a connection system which, instead of directly contacting cable wires (corresponding to the conductors) through the insulation displacement terminals, can be used to make contact between a two-wire cable and a pair of contact elements.

Abstract
Description
Die Erfindung betrifft eine Anschlussvorrichtung und ein Anschlusssystem für eine Mehrzahl, von elektrisch isolierten Leitern.The invention relates to a connection device and a connection system for a plurality of electrically insulated conductors.
Für die Verbindung von Telefon- oder Datenleitungen in Telefonzentralen oder Verteilersystemen werden oft Anschlussvorrichtungen, bspw. Anschlussleisten zur Verfügung gestellt. Diese besitzen in der Regel eine Mehrzahl von Führungen für erste Leitungen ("ankommende Leitungen"), eine Mehrzahl von Führungen für zweite Leitungen ("abgehende Leitungen") sowie Kontaktelemente zur Verbindung je einer ersten mit einer zweiten Leitung. Bevorzugt sind Anschlussvorrichtungen, die lötfrei für isolierte Leiter vorgesehen sind und auf der ,Isolation Displacement Contact' (IDC)-Technik beruhen. Die Kontaktelemente besitzen dann vorzugsweise je mindestens zwei Schneidklemmen oder - weniger bevorzugt - zwei Piercingkontakte oder eine Schneidklemme und einen Piercingkontakt.For the connection of telephone or data lines in telephone exchanges or distribution systems often connecting devices, eg. Terminal strips are provided. These usually have a plurality of guides for first lines ("incoming lines"), a plurality of guides for second lines ("outgoing lines") and contact elements for connecting each of a first with a second line. Preference is given to connection devices which are provided solderless for insulated conductors and based on the Isolation Displacement Contact (IDC) technique. The contact elements then preferably each have at least two insulation displacement terminals or, less preferably, two piercing contacts or a cutting terminal and a piercing contact.
Solche Vorrichtungen sind in mannigfaltigen Ausführungsformen bekannt, und viele davon sind am Markt erhältlich. Als Schriften, welche solche Vorrichtungen zeigen, seien beispielhaft die
Aus der europäischen Offenlegungsschrift
Bei Anschlussvorrichtungen der genannten Art ergeben sich jeweils mindestens einige der folgende Problemkreise.
- 1. Übersprechverhalten zwischen benachbarten Kontaktelement-Paaren. Dieses fällt insbesondere bei der Datenübertragung ins Gewicht. Je höher die Datenübertragungsrate, desto grösser wird die Problematik. Um die Datenübertragungssicherheit zu gewährleisten müssten daher die Kontaktelemente von Anschlussvorrichtungen für höhere Übertragungsfrequenzen möglichst weit auseinander angeordnet werden oder alle Leisten müssten mit kompensierenden Funktionalitäten ausgerüstet sein. Dies ist jedoch unerwünscht bzw. aus Platz- und Kostengründen vielfach nicht möglich.
- 2. Einfache Beschaltbarkeit. Es besteht ein naturgemässes Bedürfnis, den Beschaltungsvorgang möglichst einfach und komfortabel zu machen. Die Notwendigkeit von komplizierten Werkzeugen ist zu vermeiden.
- 3. Herstellungskosten. Auf dem Markt für Ausrüstungen für die Telekommunikation besteht ein enormer Preisdruck.
- 1. Crosstalk behavior between adjacent contact element pairs. This is particularly significant in data transmission. The higher the data transfer rate, the greater the problem becomes. In order to ensure data transmission security, therefore, the contact elements of connection devices for higher transmission frequencies would have to be arranged as far apart as possible or all strips would have to be equipped with compensating functionalities. However, this is undesirable or often not possible due to space and cost reasons.
- 2. Easy to connect. There is a natural need to make the wiring process as simple and comfortable as possible. The need for complicated tools is to be avoided.
- 3. Production costs. There is enormous price pressure in the telecommunications equipment market.

Solche Anschlussvorrichtungen mit Trennkontakten sind aufgrund ihrer vielseitigen Funktionalität vorteilhaft für spezielle Anwendungen, sind aber aufwändig in der Herstellung, bestehen aus vielen Einzelteilen und benötigen aus geometrischen Gründen ein mehrteiliges Gehäuse. Ausserdem sind - ebenfalls aus geometrischen Gründen - die ankommende und die abgehende Leitung auf der gleichen Seite des Gehäuses und in gleicher Richtung geführt, was ein präzises Abschneiden der Leitungen durch ein separates Messer bedingt und zu unkontrollierten Kontakten zwischen Leitern führen kann.Such connection devices with isolating contacts are advantageous for special applications because of their versatile functionality, but are complex to manufacture, consist of many individual parts and require a multi-part housing for geometric reasons. In addition - also for geometric reasons - the incoming and outgoing line on the same side of the housing and out in the same direction, which requires a precise cutting of the lines by a separate knife and can lead to uncontrolled contacts between conductors.
Allen Vorrichtungen gemäss den vorstehend erwähnten Schriften ist gemeinsam, dass sie für grosse Übertragungsraten von bspw. 100 Mbit/s oder mehr aufgrund des Übersprechverhaltens nicht geeignet wären, ausser sie würden sehr gross dimensioniert. Ausserdem sind sie teilweise komplex (d.h. teuer) in der Herstellung und teilweise aufwändig in der Beschaltung,All devices according to the above-mentioned documents have in common that they would not be suitable for high transmission rates of, for example, 100 Mbit / s or more because of the crosstalk behavior, unless they were dimensioned very large. In addition, they are sometimes complex (i.e., expensive) to manufacture and sometimes expensive to wire,
Es ist demnach Aufgabe der Erfindung, eine Anschlussvorrichtung zu schaffen, welche auch für hohe Übertragungsraten bei kleinen Dimensionen eine genügende, normgemässe Datenübertragungssicherheit gewährleistet. Eine einfache Beschaltbarkeit und geringe Herstellungskosten sollten vorzugsweise ebenfalls gewährleistet sein.It is therefore an object of the invention to provide a connection device which ensures a sufficient, standard data transmission security even for high transmission rates in small dimensions. Simple Beschaltbarkeit and low production costs should preferably also be guaranteed.
Die erfindungsgemässe Vorrichtung nach Anspruch 1 besitzt ein Gehäuse, das vorzugsweise einstückig ist und in welchem eine Mehrzahl von einstückigen Kontaktelementen verläuft, welche je mindestens einen ersten und mindestens einen zweiten Schneidklemm- oder Piercingkontakt aufweist. Zwischen dem ersten und dem zweite Kontakt jedes Kontaktelements verläuft eine Übergangspartie. Die Kontaktelemente sind in an sich bekannter Art paarweise angeordnet. Gemäss der Erfindung sind nun die Kontaktelemente asymmetrisch, dergestalt, dass die Übergangspartie so ausgebildet ist, dass die Übergangspartien der beiden Kontaktelemente der Paare näher beieinander sind als die Übergangspartien benachbarter Kontaktelemente verschiedener Paare.The inventive device according to
Durch diese unterschiedlichen Abstände der Übergangspartien wird das Übersprechverhalten zwischen benachbarten Paaren bei feststehenden Abständen der Kontakte reduziert. Die unterschiedlichen Abstände der Übergangspartien kommen durch eine asymmetrische Ausgestaltung der Kontaktelemente zustande, Dadurch ergibt sich eine Reihe von Vorteilen. Ein erster Vorteil ist, dass die Schneidklemm- bzw. Piercingkontakte bei Bedarf äquidistant angeordnet sein können. Die asymmetrisch Ausformung sorgt dafür, dass die für das Übersprechverhalten hauptsächlich relevanten Abschnitte des Kontaktelementes - das sind die, in denen Strom fliesst - trotzdem optimiert, d.h. zwischen den verschiedenen Paaren möglichst weit voneinander, angeordnet sind. Dies ermöglicht, ohne Änderung von Dimensionen im Vergleich zu bestehenden Anschlussvorrichtungen, die Erfordernisse einer höheren Übertragungsrate zu erfüllen. Beispielsweise kann aufgrund der Erfindung eine Anschlussvorrichtung der Kategorie 5 gemäss ISO/IEC 11801 (2002) entsprechen, und dies mit Dimensionen, wie sie von einer bestehenden Vorrichtung der Kategorie 3 bekannt ist. Stecker, Buchsen etc. des bestehenden Systems können für die höhere Kategorie 5 also weiterverwendet werden. Auch Anschlussvorrichtungen der Kategorie 6 lassen sich mit der Erfindung auf engem Raum verwirklichen, wobei dafür vorzugsweise Schirmbleche zwischen den Kontaktelement-Paaren eingesetzt werden.Due to these different distances of the transition parts, the crosstalk behavior between adjacent pairs is reduced at fixed distances of the contacts. The different distances of the transition parts come about through an asymmetrical design of the contact elements, resulting in a number of advantages. A first advantage is that the insulation displacement or piercing contacts can be arranged equidistantly if required. The asymmetric shape ensures that the sections of the contact element which are mainly relevant for the crosstalk behavior - that is, those in which current flows - are nevertheless optimized, ie. between the different pairs as far as possible from each other, are arranged. This allows to meet the requirements of a higher transmission rate without changing dimensions compared to existing connection devices. For example, according to the invention, a terminal device may conform to
Durch den erfindungsgemässen Ansatz wird ermöglicht, dass das Gehäuse einstückig ist. Die Herstellung des Gehäuses als ein einziges bspw. Spritzgussteil hat bedeutende Vorteile: die Herstellungskosten sind geringer als bei mehrteiligen Gehäusen. Der erfindungsgemässe Aufbau ermöglicht das einfache Einschieben der Kontaktelemente in das einstückige Gehäuse. Für das Zusammensetzen der Anschlussvorrichtung müssen also im einstückigen Gehäuse lediglich Kammern für die Kontaktelemente vorgesehen sein.The inventive approach makes it possible that the housing is in one piece. The production of the housing as a single example. Injection molded part has significant advantages: the manufacturing cost is lower than in multi-part housings. The inventive structure allows easy insertion of the contact elements in the one-piece housing. For the assembly of the connection device so only chambers for the contact elements must be provided in the one-piece housing.
Ausserdem können als weiterer Vorteil die Kontaktelemente im Wesentlichen flächig ausgestaltet sein und in einer gemeinsamen Ebene liegen. Das ist herstellungstechnisch besonders günstig: Alle Kontaktelemente oder mindestens Gruppen von Kontaktelementen können gemeinsam aus einem Blech gestanzt werden. Nach eventuellen Verformungen, insbesondere durch Prägen und/oder Scheren, können sie gemeinsam, durch einen Transportstreifen (Steg) zusammengehalten, ins Gehäuse eingesetzt werden.In addition, as a further advantage, the contact elements can be designed substantially flat and lie in a common plane. This is manufacturing technology particularly favorable: all contact elements or at least groups of contact elements can be punched together from a sheet. After possible deformations, in particular by embossing and / or shearing, they can be used together, held together by a transport strip (web), inserted into the housing.
Wenn die Kontaktelemente mindestens einen im Wesentlichen flächigen Abschnitt aufweisen, sind sie bspw. bezüglich derjenigen Ebene asymmetrisch, welche die beiden Schneidklemm- oder Piercingkontakte verbindet und senkrecht zum flächigen Abschnitt verläuft.If the contact elements have at least one substantially flat section, they are, for example, asymmetrical with respect to that plane which connects the two insulation displacement or piercing contacts and runs perpendicular to the flat section.
Die Kontaktelemente weisen allenfalls von der flächigen Konfiguration abweichende, bspw. durch Prägen beigebrachte und aus der Kontaktelement-Ebene herausragende Elemente auf. Solche können als zungenartige Rastklinken ausgebildet sein, die eine longitudinale Verschiebung der ins Gehäuse eingeführten Kontaktelemente verhindern. Als weitere aus der Kontaktelement-Ebene herausragende Elemente können Verstärkungen vorhanden sein, die an kritischen Stellen die mechanische Stabilität erhöhen und dadurch die Verwendung von sehr dünnen Blechen erlauben. Solche Verstärkungen können insbesondere dazu dienen, die Kräfte der beiden Gabeln eines Schneidklemmkontaktes zu gewährleisten.The contact elements have at best deviating from the flat configuration, for example, by embossing taught and protruding from the contact element level elements. Such may be formed as tongue-like detents that prevent a longitudinal displacement of the inserted into the housing contact elements. As further elements protruding from the contact element level, reinforcements may be present which increase the mechanical stability at critical points and thereby permit the use of very thin metal sheets. Such reinforcements can serve in particular to ensure the forces of the two forks of an insulation displacement contact.
Die ersten und zweiten Leiter können in an sich bekannter Art im Bereich, in dem sie kontaktiert werden, im Wesentlichen parallel zueinander und senkrecht zu den Kontaktelementen verlaufen. Ausserdem sind sie im Allgemeinen an einander gegenüberliegenden Seiten ("vorne" und "hinten") des Gehäuses geführt, wenn sie kontaktiert sind. Obwohl eine solche Ausgestaltung bevorzugt ist, kann die Erfindung auch für Anschlussvorrichtungen verwendet werden, in denen die ersten und zweiten Leiter nicht parallel sind (abgewinkelte Anschlussvorrichtung). Dies kann bspw. mit gebogenen Kontaktelementen realisiert werden.The first and second conductors can run in a manner known per se in the region in which they are contacted, substantially parallel to each other and perpendicular to the contact elements. In addition, they are generally guided on opposite sides ("front" and "rear") of the housing when in contact. Although such a configuration is preferred, the invention can also be used for connection devices in which the first and second conductors are not parallel (angled connection device). This can be realized, for example, with bent contact elements.
Oft sind die einander entsprechenden Kontaktelemente jedes Kontaktelement-Paares (d.h. alle "linken" bzw. alle "rechten" Kontaktelemente jedes Paares) identisch ausgebildet. Jedes Paar enthält dann je ein erstes und ein zweites Kontaktelement, wobei das erste und das zweite Kontaktelement sich durch ihre Ausformung oder Orientierung unterscheiden. Innerhalb des Kontaktelement-Paares sind also die Kontaktelemente bei festgelegter Orientierung erfindungsgemäss nicht identisch. In vielen bevorzugten Ausführungsformen sind hingegen das erste und zweite Kontaktelement jedes Kontaktelement-Paares zueinander spiegelbildlich.Often, the corresponding contact elements of each contact element pair (i.e., all "left" and "right" contact elements of each pair, respectively) are identical. Each pair then contains a first and a second contact element, wherein the first and the second contact element differ by their shape or orientation. Within the contact element pair, therefore, the contact elements are not identical according to the invention when the orientation is fixed. In many preferred embodiments, however, the first and second contact element of each contact element pair are mirror images of each other.
Es können also quasi zwei Typen von Kontaktelementen, "rechte" und "linke" bzw. erste und zweite vorhanden sein. Die ersten und zweite Kontaktelemente können eine identische Form haben und sich nur durch die Orientierung unterscheiden. D.h. die zweiten Kontaktelemente sind dann erste Kontaktelemente, die bspw. um 180° um eine longitudinale Achse gedreht sind. Dies gilt insbesondere in den Fällen, in welchen die Kontaktelemente keine aus der Ebene herausragende Elemente (Rastklinken, Verstärkungen etc.) aufweisen.Thus, there can be virtually two types of contact elements, "right" and "left" or first and second. The first and second contact elements may have an identical shape and differ only by orientation. That is, the second contact elements are then first contact elements, which are, for example, rotated by 180 ° about a longitudinal axis. This applies in particular in the cases in which the contact elements have no protruding from the plane elements (latches, reinforcements, etc.).
In die - zu diesem Zweck vergrösserten - Zwischenräume zwischen Übergangspartien von Kontaktelementen benachbarter Paare können Abschirmelemente eingeschoben werden. Solche sind insbesondere bei Anschlussvorrichungen vorteilhaft, die für hohe Datenübertragungsraten vorgesehen sind: sie ermöglichen eine kompaktere Bauweise bei Einhaltung der Normen (bspw. Kategorie 6).In the - for this purpose enlarged - spaces between transition sections of contact elements of adjacent pairs shielding elements can be inserted. Such are particularly advantageous in connection devices which are provided for high data transmission rates: they enable a more compact design while complying with the standards (eg category 6).
Das Gehäuse kann in an sich bekannter Art Einlegeschlitze für die Leiter aufweisen. Durch Einlegen von isolierten Leitern in die Einlegeschlitze und das anschliessende Einpressen in den Kontakt werden die Leiter kontaktiert, da die Schneidklemmen bzw. Piercing-Spitzen der Kontakte in diese Schlitze hineinragen. Das Einschieben der Leiter - also das Beschalten - kann unter Zuhilfenahme eines Beschaltungswerkzeugs erfolgen.The housing may have insertion slots for the conductors in a manner known per se. By inserting insulated conductors into the insertion slots and then pressing them into the contact, the conductors are contacted because the insulation piercing tips or piercing tips of the contacts protrude into these slots. The insertion of the conductors - ie the wiring - can be done with the help of a Beschaltungswerkzeugs.
Weiter kann das Gehäuse Klinken zur Befestigung auf einem Montagekanal aufweisen. Diese können dergestalt symmetrisch sein, dass ein Aufklinken auf den Montagekanal in zwei Orientierungen möglich ist. In der einen Orientierung liegt dann eine erste Seite (für die Beschaltung der ersten, hier "ankommenden" Leitungen) und in der anderen Orientierung eine zweite Seite (für die Beschaltung der zweiten, hier "abgehenden" Leitungen) vom und ist hierdurch leicht zugänglich. Derartige Klinken sind bspw. aus der
Gemäss der Erfindung sind den Kontaktelementen je zwei Messer zugeordnet. Durch dieses bzw. diese wird eine Überlänge eines Leiters gleich beim Beschalten abgetrennt. Dadurch, dass das Messer in der Anschlussvorrichtung integriert ist, kann das Beschaltungswerkzeug sehr einfach ausgestaltet sein. Trotzdem ist für das Beschalten und das Abtrennen von Überlängen nur ein einziger Arbeitsschritt notwendig. Lösungen, bei denen ein Messer am Beschaltungswerkzeug vorgesehen ist, sind im Gegensatz komplizierter.According to the invention, the contact elements are each assigned two knives. By this or this excess length of a conductor is disconnected as soon as the wiring. The fact that the knife is integrated in the connection device, the Beschaltungswerkzeug can be designed very simple. Nevertheless, only one single step is necessary for connecting and disconnecting excess lengths. Solutions in which a knife is provided on the wiring tool are in contrast more complicated.
Das Messer bzw. mindestens ein Messer kann als vom Kontaktelement separates Bauteil vorgesehen sein. Dies hat herstellungstechnische Vorteile: Das Messer (bzw. seine Schneidkante) muss naturgemäss die Voraussetzung erfüllen, dass es in einer anderen Ebene als die Schneidklemme bzw. der Piercingkontakt vorgesehen ist. Aus dem Stand der Technik ist bekannt, dass das Messer einstückig mit dem Kontaktelement ausgebildet ist. Dann kann der genannten Voraussetzung nur entsprochen werden, wenn das Kontaktelement (mit Schneidkante) dreidimensional, also nicht in einer Ebene, ausgeformt ist. Nach der Herstellung durch Stanzen aus einem Blech müssen gemäss dem Stand der Technik also noch Umformungen am Element vorgenommen werden, was aufwendig ist. Ein weiterer Vorteil des Messers als separates Bauteil ist, dass die Materialwahl bei den Bauteilen Kontaktelement und Messer optimiert werden kann. Beispielsweise kann beim Messer ein härteres Material als beim Kontaktelement gewählt werden.The knife or at least one knife can be provided as a separate component from the contact element. This has manufacturing advantages: The knife (or its cutting edge) must naturally meet the condition that it is provided in a different plane than the insulation displacement terminal or the piercing contact. From the prior art it is known that the knife is formed integrally with the contact element. Then, the above condition can only be met if the contact element (with cutting edge) is three-dimensional, ie not in a plane formed. After production by punching from a sheet must therefore be made according to the prior art, conversions on the element, which is expensive. Another advantage of the knife as a separate component is that the choice of material in the components contact element and knife can be optimized. For example, a harder material than the contact element can be selected in the knife.
Besonders bevorzugt ist ein Aufbau, bei welchem die kontaktierten Leiter nach dem Beschaltungsvorgang das Messer nicht mehr berühren. Dann trägt das Messer nicht zum Übersprechverhalten bei, und die Kapazität der Anordnung wird kleiner, was auch Verluste minimiert. Auch das elektrisch Potential des Messers ist dann nicht relevant, und im Prinzip kann eine elektrische Verbindung zwischen den Messern benachbarter Kontaktelemente bestehen. Die Anschlussvorrichtung kann sogar so ausgestaltet sein, dass ein Schneidelement mehrere Messer bildet und unter Umständen eine einzige, gemeinsame, quer zur Leiterrichtung verlaufende Schneidkante aufweist, die Überlängen mehrerer benachbarten Leiter abtrennt.Particularly preferred is a structure in which the contacted conductors no longer touch the knife after the Beschaltungsvorgang. Then the knife does not contribute to the crosstalk behavior, and the capacity of the assembly becomes smaller, which also minimizes losses. Also, the electric potential of the blade is then not relevant, and in principle can exist an electrical connection between the blades of adjacent contact elements. The connecting device can even be designed so that a cutting element forms a plurality of knives and may have a single, common, running transversely to the conductor direction cutting edge, which separates excess lengths of several adjacent conductors.
Nebst dem Gehäuse, den Kontaktelementen und ggf. den Messern kann die Anschlussvorrichtung noch weitere Komponenten aufweisen.In addition to the housing, the contact elements and possibly the knives, the connection device may have further components.
Beispielsweise kann auf der einen Seite (typischerweise auf der Seite der zweiten, "abgehenden" Leiter) ein beschriftbarer Beschaltungsdeckel als Abdeckung vorhanden sein. Durch diesen können die Einlegeschlitze abgedeckt und werden, und die Leiterpaare können gemäss ihrer Funktion beschriftet werden.For example, on one side (typically on the side of the second, "outgoing" conductor) a writable wiring cover may be present as a cover. Through this, the insertion slots can be covered and become, and the pairs of conductors can be labeled according to their function.
Als weitere zusätzliche Komponente kann die Anschlussvorrichtung - typischerweise für die Seite der ersten, "ankommenden" Leiter - mit einer weiteren Abdeckung versehen sein, die eine Zugentlastung für ein mehradriges Kabel aufweisen kann.As a further additional component, the connection device - typically for the side of the first, "incoming" conductors - may be provided with a further cover, which may have a strain relief for a multi-core cable.
Ebenfalls zusätzlich kann in einem Beschaltungsdeckel und/oder einer Abdeckung oder direkt in Einlegeschlitzen für die Leiter ein Gel oder Wetterschutzfett vorhanden sein, welches als Korrosionsschutz wirkt.In addition, a gel or weather protection grease may be present in a wiring cover and / or a cover or directly in insertion slots for the conductors, which acts as corrosion protection.

Die Kontaktelemente sind asymmetrisch ausgeformt und zwar so, dass auch bei äquidistanter Anordnung der Schneidklemmkontakte die Übergangspartien 3.3 der beiden Kontaktelemente eines Kontaktelement-Paares näher zueinander liegen als zur Übergangspartie eines Kontaktelementes eines benachbarten Paares. Dies im Unterschied zum bekannten Stand der Technik, gemäss welchem die Kontaktelemente jeweils symmetrisch sind (die Symmetrieebene ist dabei die in Längsrichtung, zur Kontaktelement-Ebene senkrecht verlaufende Ebene).The contact elements are asymmetrically shaped in such a way that even with equidistant arrangement of the insulation displacement contacts, the transitional parts 3.3 of the two contact elements of a contact element pair closer to each other than the transition part of a contact element of an adjacent pair. This, in contrast to the known prior art, according to which the contact elements are each symmetrical (the plane of symmetry is in the longitudinal direction, the contact element plane perpendicular plane).
