Description

Die Erfindung betrifft einen an abisolierte Enden elektrischer Leitungen anschlagbaren Crimpkontakt für Stecksysteme mit eckigen Kontaktkammern, welcher ein Kontaktstück, einen Übergangsbereich, einen Drahtcrimp und einen Isolationscrimp aufweist.The invention relates to electrical at stripped ends Crimp contact for connector systems with angular contact chambers, which is a contact piece, one Transition area, a wire crimp and an insulation crimp having.

Stecksysteme mit mehreren Kontaktkammern erfordern vielfach eine geringe Baugröße darin enthaltener Kontakte, wobei die Durchmesser anzuschließender Leitungen oft kaum geringer sind als der Teilungsabstand der einzelnen Kontaktkammern. Insbesondere bei der Verwendung von Crimpkontakten kann es speziell im Bereich des Isolationscrimps zu Platzproblemen kommen. Beim Bestücken eines Steckergehäuses ist es außerdem wichtig, daß die Kontakte mit geringer Kraft in die Kontaktkammern eingeführt werden können, ohne daß die Kontakte dabei verbogen werden, da durch eine Verformung zusätzliche Platzprobleme entstehen. Bisher wurde dies Problem dadurch gelöst, die zulässigen Drahtgrößen bei runden oder B-förmigen Isolationscrimps zu begrenzen.Plug systems with multiple contact chambers often require a small size of the contacts contained therein, the Lines to be connected are often hardly smaller than the pitch of the individual contact chambers. Especially when using crimp contacts it can be special Space problems arise in the area of the insulation crimp. When assembling a connector housing, it is also important that the contacts with little force in the contact chambers can be inserted without the contacts being bent because additional deformation problems due to deformation arise. So far, this problem has been solved by the permissible wire sizes for round or B-shaped insulation crimp to limit.

Der Erfindung liegt das Ziel zugrunde, einen Crimpkontakt zu schaffen, bei welchem die obengenannten Nachteile bzw. Probleme nicht auftreten.The aim of the invention is to provide a crimp contact create, in which the above disadvantages or problems do not occur.

Erfindungsgemäß wird dies durch einen an abisolierte Enden elektrischer Leitungen anschlagbaren Crimpkontakt für Stecksysteme mit eckigen Kontaktkammern erreicht, welcher ein Kontaktstück, einen sich daran anschließenden Übergangsbereich, einen Drahtcrimp und am leitungsseitigen Ende einen Isolationscrimp aufweist, wobei der Isolationscrimp eine ebene Grundseite mit zwei sich daran anschließenden Schenkeln besitzt und in einem an eine Leitung angeschlagenen Zustand ein im wesentlichen rechteckförmiges Profil aufweist. According to the invention, this is done by stripped ends Crimp contact for plug-in systems reached with square contact chambers, which is a contact piece, an adjoining transition area, a wire crimp and an insulation crimp at the line end has, the insulation crimp a flat Has base with two adjoining legs and in a condition struck on a pipe has a substantially rectangular profile.

Mit einem erfindungsgemäßen Crimpkontakt wird der in Stecksystemen mit eckigen Kontaktkammern zur Verfügung stehende Raum effizienter ausgenutzt, wobei insbesondere ein problemloses Bestücken der einzelnen Kontaktkammern mit Crimpkontakten gewährleistet ist. Da eine Ausführung eckiger Isolationscrimps während der Crimpverarbeitung tendenziell schwieriger zu realisieren ist als bei bisher üblichen Formen, bedarf es vorteilhafterweise unterstützender Maßnahmen am Kontakt.With a crimp contact according to the invention, it is used in plug systems available space with square contact chambers exploited more efficiently, in particular a problem-free one Equipping the individual contact chambers with crimp contacts guaranteed is. Because an execution of angular insulation crimp tend to be more difficult to realize during crimp processing than with conventional forms, it is advantageously required supportive measures on contact.

In einer vorteilhaften Ausgestaltung weisen die Schenkel des Isolationscrimps an ihren freien Enden Sollknickstellen auf. Für die Realisierung dieser Sollknickstellen bieten sich mehrere Alternativen an. In einer vorteilhaften Ausgestaltung können die Schenkel des Isolationscrimps im Bereich der Sollknickstellen an ihrer Innenseite jeweils eine Prägung aufweisen, welche ein rechtwinkliges Umknicken der freien Enden der Isolationscrimpschenkel ermöglicht. Alternativ können die Schenkel des Isolationscrimps im Bereich der Sollknickstellen mit seitlichen Schlitzen oder mit jeweils einem mittigen Schlitz versehen sein. Eine weitere Möglichkeit, definierte Sollknickstellen an den freien Enden der Isolationscrimpschenkel zu realisieren, sind ab den Sollknickstellen verschmälert ausgeführte Endabschnitte der Isolationscrimpschenkel. Unterstützende Maßnahmen, welche ein rechtwinkliges Um-biegen der Isolationscrimpschenkel ermöglichen, sind am Übergang zwischen der Grundseite des Isolationscrimps und den Crimpschenkeln nicht erforderlich, weil dort geringere Biegeänderungen bei der Verarbeitung erforderlich sind, um rechtwinklige Biegungen zu erzielen. Derartige Verformungen der Schenkel sind bereits mit einem geeigneten Konfektionierungswerkzeug erreichbar.In an advantageous embodiment, the legs of the Isolation crimps at their free ends to predetermined kinks. There are several options for realizing these predetermined kinks Alternatives. In an advantageous embodiment can the legs of the insulation crimp in the area of the predetermined kinks each have an embossing on the inside, which causes the free ends of the Insulation crimp leg allows. Alternatively, the Leg of the insulation crimp in the area of the predetermined kinks with side slits or with one in the middle Slot. Another way defined Target kinks at the free ends of the insulation crimp legs to be realized are narrowed from the predetermined kinks executed end sections of the insulation crimp legs. Supporting measures that bend at right angles the insulation crimp legs allow are at the transition between the base of the insulation crimp and the Crimp legs are not required because there are fewer changes in bending when processing are required to be rectangular To achieve bends. Such deformations of the Legs are already with a suitable assembly tool reachable.

In einer vorteilhaften Ausgestaltung weisen die Schenkel des Isolationscrimps jeweils mindestens eine Aussparung auf. Ebenso kann der Isolationscrimp an seiner Grundseite mit mindestens einer Aussparung versehen sein. Der Vorteil dieser Maßnahmen ist in der Schaffung weiteren Stauraums für die Isolation einer mit dem Crimpkontakt verbundenen elektrischen Leitung zu sehen.In an advantageous embodiment, the legs of the Insulation crimp each have at least one recess. Likewise, the insulation crimp on its base side with at least be provided with a recess. The advantage of this Measures is in creating more storage space for that Isolation of an electrical connected to the crimp contact Line to see.

In einer weiteren Ausgestaltung sind die Schenkelabschnitte senkrecht zur Grundseite des Isolationscrimps in einem an eine Leitung angeschlagenen Zustand unterschiedlich hoch. Erreicht wird dies durch eine unterschiedliche Länge der Isolationscrimpschenkel, durch eine unterschiedliche Position der Sollknickstellen an den Isolationscrimpschenkeln sowie durch entsprechende Ausformungen am Konfektionierungswerkzeug. Der Vorteil einer derartigen asymmetrischen Ausgestaltung der Crimpschenkel ist darin zu sehen, daß der Querschnitt des Isolationscrimps der Kontur einer asymmetrisch ausgesparten Kontaktkammer angepaßt werden kann, um so den Raum optimal zu nutzen. Asymmetrische Kontaktkammern sind beispielsweise sinnvoll zur Kennzeichnung von Kontakten mit unterschiedlichen Polaritäten. Ferner können sich die Schenkel des Isolationscrimps in einem an eine Leitung angeschlagenen Zustand an ihren freien Enden auch überlappen.In a further embodiment, the leg sections perpendicular to the base of the insulation crimp in one to one Line struck state differently high. Reached this is due to a different length of the insulation crimp legs, by a different position of the Target kinks on the insulation crimp legs and through corresponding formations on the assembly tool. Of the Advantage of such an asymmetrical configuration of the Crimp legs can be seen in the fact that the cross section of the Isolation crimp the contour of an asymmetrically recessed Contact chamber can be adjusted to optimize the space use. Asymmetrical contact chambers are for example useful for identifying contacts with different Polarities. Furthermore, the legs of the insulation crimp in a condition struck on a pipe also overlap at their free ends.

    • Figur 1 zeigt einen fertig verarbeiteten erfindungsgemäßen Crimpkontakt 1, welcher an ein abisoliertes Ende einer elektrischen Leitung 2 angeschlagen ist. Der Crimpkontakt 1 besteht aus einem Kontaktstück 3, einem sich daran anschließenden Übergangsbereich 4, einem Drahtcrimp 5 und einem Isolationscrimp 6. Im Gegensatz zum B-förmigen Drahtcrimp 5 weist der Isolationscrimp 6 in Anpassung an die Form von Kontaktkammern eines Steckersystems ein rechteckförmiges Profil auf.Figure 1 shows a finished processed according to the invention Crimp contact 1, which at an stripped end of an electrical Line 2 is struck. The crimp contact 1 exists from a contact piece 3, an adjoining one Transition area 4, a wire crimp 5 and an insulation crimp 6. In contrast to the B-shaped wire crimp 5 points the insulation crimp 6 in adaptation to the shape of contact chambers of a connector system on a rectangular profile.

    Figur 2 zeigt einen Crimpkontakt gemäß Figur 1, jedoch in unverarbeitetem Zustand. Der Drahtcrimp 5 weist einen parabelförmigen Querschnitt auf, während sich der Isolationscrimp 6 in eine ebene Grundseite 7 und zwei sich daran anschließende Isolationscrimpschenkel 8 und 9 gliedert. Eine ebene Grundseite 7 muß bereits vor der Crimpverarbeitung sichergestellt sein, da sich eine derartige Ausformung nur schwer mit einem entsprechenden Konfektionierungswerkzeug herstellen läßt. Bei der Verarbeitung des Crimpkontaktes ist im Übergangsbereich zwischen der Grundseite 7 und den Crimpschenkeln 8 und 9 lediglich eine geringe Biegewinkeländerung erforderlich, während am Übergangsbereich zwischen den freien Enden 10 und 11 der Schenkel und den Crimpschenkeln 8 und 9 eine deutliche Biegewinkeländerung notwendig ist.FIG. 2 shows a crimp contact according to FIG. 1, but in an unprocessed state Status. The wire crimp 5 has a parabolic shape Cross section while the insulation crimp 6 in a flat base side 7 and two adjoining it Insulation crimp legs 8 and 9 divided. A flat base 7 must be ensured before crimping be, since such a formation is difficult with one corresponding manufacturing tool can be produced. At The processing of the crimp contact is in the transition area between the base 7 and the crimp legs 8 and 9 only a small change in bend angle is required while at the transition area between the free ends 10 and 11 the leg and the crimp legs 8 and 9 a clear Bending angle change is necessary.

    Die Figuren 3a bis 3c zeigen mehrere Ausgestaltungsformen eines bereits verarbeiteten Isolationscrimps im Querschnitt, wobei auf eine explizite Darstellung der elektrischen Leitung verzichtet wird. Durch unterschiedlich hohe Positionierung von Sollknickstellen an den beiden Isolationscrimpschenkeln 8 und 9 sowie durch eine entsprechende Ausgestaltung des Konfektionierungswerkzeuges weisen die rechtwinklig zur Grundfläche 7 orientierten Abschnitte der Crimpschenkel 8 und 9 eine unterschiedliche Höhe auf. Zusätzlich überlappen sich die freien Enden 10 und 11 der Isolationscrimpschenkel 8 und 9 (Figur 3a). Dies hat den Vorteil, daß sich die Isolationscrimpschenkel 8 und 9 an ihren freien Enden 10 und 11 während des Verarbeitungsvorganges aufeinander abstützen können, um eine optimale rechtwinklige Ausbildung zu erzielen. Bei geeigneten Maßnahmen zur Realisierung der Sollknickstellen zwischen den Endabschnitten 10 und 11 und den Crimpschenkeln 8 und 9 ist es auch möglich, daß die Endabschnitte 10 und 11 der Crimpschenkel lediglich aneinander angrenzen (Figur 3b). Wie anhand von Figur 3c zu sehen ist, ist auch eine symmetrische Ausbildung der Isolationscrimpschenkel 8 und 9 sowie ihrer Endabschnitte 10 und 11 möglich.Figures 3a to 3c show several embodiments of a cross section of already processed insulation crimp, being on an explicit representation of the electrical wire is waived. Through different positions of predetermined kinks on the two insulation crimp legs 8 and 9 and by a corresponding configuration of the assembly tool point at right angles to the base 7 oriented sections of the crimp legs 8 and 9 a different height. In addition, they overlap the free ends 10 and 11 of the insulation crimp legs 8 and 9 (Figure 3a). This has the advantage that the insulation crimp legs 8 and 9 at their free ends 10 and 11 during support each other during the processing process, to achieve an optimal rectangular training. At suitable measures for realizing the predetermined kinks between the end sections 10 and 11 and the crimp legs 8 and 9, it is also possible for the end sections 10 and 11 the crimp legs only adjoin one another (FIG. 3b). As can be seen from FIG. 3c, there is also a symmetrical one Training the insulation crimp legs 8 and 9 and their End sections 10 and 11 possible.

    Die Figuren 4a bis 4d zeigen geeignete Maßnahmen auf, um definierte Sollknickstellen im Übergangsbereich zwischen den Isolationscrimpschenkeln 8 und 9 und den Endabschnitten 10 und 11 zu realisieren. Figur 4a zeigt eine Ausgestaltungsform mit an der Innenseite der Crimpschenkel 8 und 9 im Bereich der Sollknickstellen angebrachten Prägungen 12, welche sich in einer Längsrichtung des Crimpkontaktes erstrecken. Alternativ können die Schenkel des Isolationscrimps 6 mit seitlichen Schlitzen 13 ausgestattet sein, welche ein Umbiegen der Endabschnitte der Crimpschenkel vereinfachen (Figur 4b). In Figur 4c ist eine Ausführungsvariante mit einem mittigen Schlitz 14 dargestellt, welcher sich in Längsrichtung des Crimpkontaktes erstreckt und durch welchen ebenfalls eine Sollknickstelle zwischen den freien Enden und den rechtwinklig zur Grundseite des Isolationscrimps 6 orientierten Schenkelabschnitten realisiert ist. Eine weitere Möglichkeit besteht darin, den Isolationscrimp 6 ab der Sollknickstelle an den Crimpschenkeln mit verschmälerten Endabschnitten 15 auszuformen (Figur 4d).Figures 4a to 4d show suitable measures to define Target kinks in the transition area between the Insulation crimp legs 8 and 9 and the end portions 10 and 11 to realize. FIG. 4a shows an embodiment with on the inside of the crimp legs 8 and 9 in the area the embossments 12 attached, which are extend in a longitudinal direction of the crimp contact. Alternatively can the legs of the insulation crimp 6 with lateral Slots 13 are equipped, which a bending of the Simplify end portions of the crimp legs (Figure 4b). In Figure 4c is a variant with a central Slot 14 shown, which is in the longitudinal direction of the Crimp contact extends and through which also one Target kink between the free ends and the right-angled 6 leg sections oriented toward the base of the insulation crimp is realized. Another option is there in, the insulation crimp 6 from the target kink form the crimp legs with narrowed end portions 15 (Figure 4d).

    Um beim Anschlagen des Isolationscrimps an ein abisoliertes Ende einer elektrischen Leitung Platz für das Isolationsmaterial zu schaffen, sind die Crimpschenkel 8 und 9 des Isolationscrimps 6 mit Aussparungen 16 versehen, in welche Isolationsmaterial des Leiters einpreßbar ist (Figur 5a). Das obere Ende der Aussparung 16 realisiert dabei gleichzeitig die Sollknickstelle für das freie Ende des Isolationscrimpschenkels. In der in Figur 5b dargestellten Ausführungsform weist auch die Grundseite 7 des Isolationscrimps 6 eine Aussparung 17 auf, wobei die Größe und die Geometrie der Aussparungen 16 an den Crimpschenkeln 8 und 9 und der Aussparung 17 an der Grundseite 7 des Isolationscrimps 6 an die jeweiligen Abmessungen des elektrischen Leiters angepaßt werden kann. Die Sollknickstellen und die Aussparungen 16 an den Isolationscrimpschenkeln sind in diesem Fall jedoch unabhängig voneinander ausgebildet.To attach the insulation crimp to a stripped End of an electrical line space for the insulation material to create, the crimp legs 8 and 9 of the insulation crimp 6 provided with recesses 16, in which insulation material the conductor can be pressed in (FIG. 5a). The top The end of the recess 16 also realizes the Target kink for the free end of the insulation crimp leg. In the embodiment shown in Figure 5b points also the base 7 of the insulation crimp 6 has a recess 17, the size and geometry of the cutouts 16 on the crimp legs 8 and 9 and the recess 17 on the Base side 7 of the insulation crimp 6 to the respective dimensions of the electrical conductor can be adjusted. The Target kinks and the recesses 16 on the insulation crimp legs are independent of each other in this case educated.
