Description
Die Erfindung betrifft einen elektrischen Verbinder mit einem Gehäuse aus Isolationsmaterial und einem im Gehäuse anordnenbaren metallischen Kontaktelement mit einem Schneidklemmkontaktbereich und einem Crimpkontaktbereich, der sich in Richtung der longitudinalen Achse eines einlegbaren Kabels an den Schneidklemmkontaktbereich anschliesst und mit diesem leitend verbunden ist.The invention relates to an electrical connector a housing made of insulation material and one in the housing arrangable metallic contact element with a Insulation displacement contact area and a crimp contact area, which is in the direction of the longitudinal axis of a insertable cable to the insulation displacement contact area connects and is conductively connected to it.
Es gibt viele Anwendungen für die es wünschenswert ist, dass man die Schneidklemmtechnik einsetzen kann. Ein Nachteil der Schneidklemmtechnik ist jedoch, dass die Kontakte sehr empfindlich gegenüber dem Durchmesser der zu kontaktierenden isolierten Leiter sind. Da aber im Normalfall davon auszugehen ist, dass man nicht von vornherein weiss, welche Kabelgrösse mit einem Schneidklemmkontakt verbunden werden soll, ist diese Technik oft nicht einsetzbar. Der Grund, warum Schneidklemmstrukturen so empfindlich gegenüber Durchmesserschwankungen sind ist, dass die Schneide, die die Isolierung durchschneiden soll, den inneren Leiter erreichen muss.There are many applications for which it is desirable that you can use insulation displacement technology. A disadvantage The insulation displacement technique, however, is that the contacts very sensitive to the diameter of the contacting insulated conductors. But since normally It can be assumed that you will not be a priori knows which cable size with an insulation displacement contact this technique is often not to be connected applicable. The reason why insulation displacement structures are like this are sensitive to fluctuations in diameter, that the cutting edge that is to cut through the insulation must reach the inner leader.

Die beiden Kammern sind über einen Durchgang miteinander verbunden der von einem Verbindungssteg zwischen dem Schneidklemmkontaktbereich und dem zusätzlichen Anschlussbereich durchsetzt ist. Es geht aus dieser Entgegenhaltung nicht hervor, wie man eine Schneidklemmstruktur für Kabel mit unterschiedlichen Durchmessern einsetzen kann.DE 43 24 841 A1 describes one method and one Device for power supply optional, electrical powered special equipment, for example in a motor vehicle.

Aus der US 4,472,596 ist ebenfalls der Einsatz von Schneidklemmstrukturen bekannt. Dabei werden Kabel oder Kabelenden zunächst in einem Zugentlastungsbereich fixiert und dann mittels einer Schneidklemmstruktur kontaktiert. Es ist jeweils ein Paar von Schneidklemmstruktur miteinander verbunden und von einem Paar von Zugentlastungsbereichen nach aussen umgeben.From US 4,472,596 is also the use of Insulation displacement structures known.

Der elektrische Verbinder weist jeweils Paare von Schneidklemmlappen für Kabel mit kleinerem Durchmesser und für Kabel mit grösserem Durchmesser auf. Die Paare von sich gegegenüberliegenden Schneidklemmlappen für Kabel mit dem grösserem Durchmesser sind dabei aussen und die Paare für Schneidklemmlappen für Kabel mit kleinerem Durchmesser innen angeordnet. Wird ein Kabel von grösserem Durchmesser in die Schneidklemmlappen eingelegt, so wird die Kontaktierung von den äusseren Schneidklemmlappen durchgeführt. In Bezug auf die inneren Schneidklemmlappen sind verschiedene Möglichkeiten denkbar. Entweder die inneren Schneidklemmlappen schneiden nicht nur die äussere Isolationshülle des Kabels ein, sondern auch den inneren Leiter. Diese teilweise Durchtrennung führt jedoch nicht zu weiteren Problemen, da das Kabel durch die Zugentlastungsbereiche gehalten wird und eine Kontaktierung der beiden Kabelteile zu einander durch die äusseren Schneidklemmkontakte und die diese verbindende Grundplatte des metallischen Kontaktelementes gewährleistet ist. Oder die inneren Schneidklemmlappen werden plastisch verformt, da sie beispielsweise leichter verformbar, da dünner als die äusseren Schneidklemmlappen sind, und das dickere Kabel wird von den inneren Schneidklemmlappen nicht beeinflusst. Es ist auch möglich, dass die eigentliche Lösung zwischen diesen beiden Extremen liegt.The electrical connector has pairs of Insulation clamps for cables with a smaller diameter and for cables with a larger diameter. The couples opposing insulation displacement tabs for Cables with the larger diameter are outside and the pairs for insulation displacement tabs for cables with smaller ones Diameter arranged inside. Will a cable from larger diameter inserted into the insulation displacement tabs, so the contacting from the outside Insulation clamps carried out. In terms of the inner ID clamps are different options conceivable. Either cut the inner ID clamps not just the outer insulation sleeve of the cable one, but also the inner conductor. This partially However, cutting does not lead to further problems, because the cable is held by the strain relief areas and contacting the two cable parts each other through the outer insulation displacement contacts and the this connecting base plate of the metallic contact element is guaranteed. Or the inner insulation displacement tabs are plastically deformed because, for example easier to deform because it is thinner than the outer ones There are cutting clamps, and the thicker cable is from does not affect the inner insulation displacement tab. It is also possible that the real solution between these both extremes.
Es ist besonders vorteilhaft, wenn das Kontaktelement in ein Gehäuse in Richtung der longitudinalen Achse eines eindringbaren Kabels einschiebbar ist. Dabei ist es von Vorteil, wenn zwei Raststellungen vorgesehen werden und in einer ersten Vorraststellung ein Kabelende in den Crimpkontaktbereich einbringbar ist und in einer zweiten Endstellung ein Kabel von oben durch das Gehäuse in den Schneidklemmkontaktbereich einbringbar ist. So wird der Crimpkontaktbereich gegen äussere Einflüsse geschützt und auch das gesamte Kontaktelement ist durch das Gehäuse stabilisiert und geschützt.It is particularly advantageous if the contact element is in a housing in the direction of the longitudinal axis of a penetrable cable can be inserted. It is from Advantage if two locking positions are provided and in a first pre-locking position one cable end in the Crimp contact area can be introduced and in a second End position a cable from above through the housing in the Insulation displacement contact area can be introduced. So it will Crimp contact area protected against external influences and also the entire contact element is through the housing stabilized and protected.
Weiter ist es von Vorteil, dass der Schneidklemmbereich und der Crimpbereich derart angeordnet sind, dass die beiden miteinander zu verbindenden Kabel miteinander fluchten und im Gehäuse im bezug auf den Gehäusegrund übereinander angeordnet sind. Dadurch ist gewährleistet, dass die Anordnung sehr kompakt ausgeführt ist und im Verlauf des durchgehenden Kabels nicht weiter stört, da das zu verbindende Kabelende mit dem durchgehenden Kabel fluchtet.It is also advantageous that the insulation displacement area and the crimp area are arranged such that the two cables to be connected together align and in the housing with respect to the housing base are arranged one above the other. This ensures that the arrangement is very compact and in The course of the continuous cable does not bother because the cable end to be connected with the continuous cable flees.
Um eine sichere Montage der Kabel zu gewährleisten ist es von Vorteil, wenn das Kontaktelement und das Gehäuse für die Vorraststellung und die Endstellung einen Anschlag aufweisen.To ensure a safe installation of the cables it is advantageous if the contact element and the housing a stop for the pre-locking position and the end position exhibit.
Der elektrische Verbinder ist dazu geeignet durchgehende Kabel unterschiedlicher Grösse mit einem Kabelende zu verbinden oder zwei Kabelenden die sich gegenüberliegen und von grösserem Durchmesser sind mit einem dritten Kabelende zu verbinden. Der Einsatz des elektrischen Verbinders geht wie folgt vor sich: Zunächst wird ein Kabelende in den Crimpkontaktbereich eingebracht und die Crimpverbindung wird geschlossen. Danach wird das Kontaktelement mit dem ersten Kabelende in das Gehäuse eingeschoben. Dann wird das zweite Kabel, ein durchgehendes Kabel, von oben durch die Öffnung des Gehäuses in den Schneidklemmkontaktbereich eingefügt. Je nach Grösse des Kabeldurchmessers schneiden nur die beiden inneren Paare von Schneidklemmlappen durch die Isolierung des Kabels und Kontaktieren den Leiter oder die beiden äusseren Paare von Schneidklemmlappen und die beiden inneren Paare von Schneidklemmlappen schneiden durch die Isolierung des Kabels und die äusseren Kontaktieren den Leiter. Die inneren Schneidklemmlappen schneiden dann den Leiter ebenfalls teilweise durch. Nachdem das Kabel eingebracht ist müssen die Zugentlastungselemente der Zugentlastungesbereiche noch geschlossen werden. Dies kann beispielsweise durch die Öffnung des Gehäuses, also von oben erfolgen.The electrical connector is suitably continuous Cables of different sizes with one cable end too connect or two cable ends facing each other and are of larger diameter with a third To connect the cable end. The use of the electrical Connector works as follows: First, a Cable end inserted in the crimp contact area and the Crimp connection is closed. Then the contact element with the first cable end in the housing inserted. Then the second cable, one through Cable, from above through the opening of the housing inserted the insulation displacement contact area. Depending on size of the cable diameter only the two inner cut Pairs of insulation clamps by isolating the Cables and contact the conductor or the two outer ones Pairs of IDCs and the two inner ones Pairs of IDCs cut through the Insulation of the cable and the external contacts Ladder. The inner insulation displacement tabs then cut also partially through the conductor. After the cable the strain relief elements of the Strain relief areas are still closed.

Ein Ausführungsbeispiel der Erfindung wird anhand der
Zeichnungen erläutert. Es zeigen:
In Figur 1 ist ein elektrischer Verbinder dargestellt.
Das Gehäuse 1 ist im wesentlichen U-förmig. Die Öffnung
des U's befindet sich in der Zeichnung oben, der Gehäusegrund
16 ist unten im Schnitt dargestellt. Es ist eine
Stufe 15 im Gehäusegrund 16 erkennbar. Auf der unteren
Ebene des Gehäusegrunds 16 befindet sich das metallische
Kontaktelement 2. In Figur 1 ist es nur teilweise eingeschoben.
Die in Figur 1 dargestellte Stellung wird als
Vorraststellung bezeichnet. Ein Anschlag 13, der an
einer Schulter des Gehäuses angreift, verhindert das
weitere Einfügen des Kontaktelementes 2 in das Gehäuse

wird durch zwei sich gegenüberliegende federnde
Elemente 17 und entsprechende Verbreiterungen im Gehäusequerschnitt
18, auf die die federnden Elemente 17
einrasten, verhindert.In Figure 1 an electrical connector is shown.
The
Zum Aufbau des metallischen Kontakts weist das metallische
Kontaktelement einen Schneidklemmkontaktbereich 3
und einen Crimpkontaktbereich 4 auf. In der Vorraststellung
des Kontaktelementes 2 im Gehäuse 1 befindet sich
der Schneidklemmkontaktbereich 3 bereits im Gehäuse
während der Crimpkontaktbereich 4 ausserhalb des Gehäuses
zugänglich ist. Crimpkontaktbereich 4 und Schneidklemmkontaktbereich
3 sind leitend miteinander verbunden.
Der Crimpkontaktbereich besteht aus zwei hintereinander
angeordneten Paaren von Crimplaschen, von denen
die vom Schneidklemmkontaktbereich 3 weiter entfernten
19 zur Fixierung eines Kabelendes 11 mit Kabelmantel
dient und die näher zum Schneidklemmkontaktbereich 3 hin
angeordneten Crimplaschen 20 zum Fixieren der abisolierten
Leiter des Kabelendes 11 dient.In order to build up the metallic contact, the metallic one

An dem Crimpkontaktbereich schliesst sich der Schneidklemmkontaktbereich
3 an. Beide Bereiche sind derart
ausgestaltet, dass darin fixierte Kabel fluchtend zueinander
ausgerichtet sind. Dabei liegen die verbundenen
Kabel im Bezug zum Gehäusegrund 16 übereinander. Der
Schneidklemmkontaktbereich 3 besteht aus den eigentlichen
Schneidklemmlappen 7 bis 10 und zwei Zugentlastungsbereichen
5 und 6. Betrachtet man den Schneidklemmkontaktbereich
3 in Richtung eines einzulegenden
Kabels, so sind hintereinander angeordnet ein Zugentlastungsbereich
5 mit beispielsweise einem Paar von
gegenüberliegenden Zungen, die zur Zugentlastung vercrimpt
werden, ein Paar von gegenüberliegenden Schneidklemmlappen
7, die für Kabel von grösserem Durchmesser
geeignet sind, zwei hintereinander angeordnete Paare von
nebeneinander angeordneten Schneidklemmlappen 8 und 9
die für Kabel von kleinerem Durchmesser geeignet sind
und ein Paar von nebeneinander angeordneten Schneidklemmlappen
10, die wiederum für Kabel von grösserem
Durchmesser geeignet sind. Das letzte Element bildet
wiederum ein Zugentlastungsbereich 6 der beispielsweise
aus zwei gegenüberliegenden Lappen bestehen können, die
zur Fixierung des Kabels zu vercrimpen sind. Der eigentliche
Schneidklemmkontaktbereich 3 besteht aus einem W-Profile
mit vier Ebenen, die jeweils ein gegenüberliegendes

dargestellt. Dabei ist ein Kabelende 11 am
Crimpkontaktbereich 4 fixiert. Die Leiter des Kabelendes
21 sind deutlich zu erkennen. Sie werden von der Crimplasche
20 gehalten. Es ist auch zu erkennen, dass die
Anschläge 13 für die Vorraststellung nicht mehr zu sehen
sind. Dies resultiert daher, dass beim Crimpvorgang
gleichzeitig die Anschläge umgebogen werden, um so das
Einführen des Kontaktelementes 2 in das Gehäuse 1 zum
Erreichen der Endstellung zu ermöglichen. Nach dem
Crimpvorgang wurde das metallische Kontaktelement 2 in
das Gehäuse 1 eingeschoben. Die federnden Elemente 17
werden dabei von einer ersten Verjüngung im Querschnitt
des Gehäuses 18 zu einer zweiten Verjüngung im Querschnitt
des Gehäuses 18' weitergeschoben. Am Kontaktelement
2 ist ein Anschlag 14' für die Endstellung vorgesehen.
Der Anschlag schlägt an der Stufe 15 im Gehäuse 1
an. In eine in Figur 1 sichtbare Vertiefung in der Gehäusewand
22 tritt ein Vorsprung 14 ein. Diese Sicherung
soll verhindern, dass die Anordnung durch Zug am in der
Figur linken Kabelende beeinflusst wird. In der Endstellung
kann dann auch ein zweites Kabel 12 in den Schneidklemmkontaktbereich
eingeführt werden. Das Kabel 12 ist
dann leitend mit dem Kabelende 11 verbunden.2 shows an arrangement according to FIG. 1 in an installation situation
