Abstract

The electrical connector of the invention has contact elements located in adjacent chambers in an insulating housing (1), each element having a crimping zone permitting bunched conductors to be connected. In addition, for each chamber in the housing, there is a slot (16) designed to hold a locking strip (31) which acts on one edge (22) of the respective contact element to produce a locking effect, In order to avoid the spread conductor ends from straying into neighbouring chambers and causing a short circuit when the locking strip (31) is inserted across the longitudinal axis of the contact elements, each crimping zone is located on that side of the wall of the part-tubular contact element (2) which is remote from the locking edge.

Description

Die Erfindung betrifft einen Leitungsstecker für eine Mehrzahl von Litzenleitern und mit folgenden Merkmalen:

  • a) in einem Gehäuse ist eine Reihe von nebeneinander liegenden Kontaktkammern ausgebildet;
  • b) in die Kontaktkammern ist jeweils ein Kontaktelement rastend einsteckbar;
  • c) jedes Kontaktelement ist zumindest in Teilbereichen hülsenförmig ausgebildet und besitzt einen Crimpbereich zum Anschluß eines Litzenleiters sowie eine durch eine Freisparung gebildete, entgegengesetzt zur Einsteckrichtung weisende Verriegelungskante und
  • d) das Gehäuse besitzt einen quer zur Einsteckrichtung der Kontaktelemente verlaufenden, über den Freisparungen der Kontaktelemente liegenden Schlitz, in welchen eine die Verriegelungskanten der Kontaktelemente hintergreifende Verriegelungsleiste einschiebbar ist.
The invention relates to a cable connector for a plurality of stranded conductors and with the following features:
  • a) a row of adjacent contact chambers is formed in a housing;
  • b) a contact element can be latched into the contact chambers;
  • c) each contact element is sleeve-shaped at least in some areas and has a crimp area for connecting a stranded conductor and a locking edge formed by a cutout and pointing opposite to the insertion direction
  • d) the housing has a slot which runs transversely to the insertion direction of the contact elements and lies above the cutouts of the contact elements and into which a locking bar engaging behind the locking edges of the contact elements can be inserted.

Derartige Leitungsstecker sind vielfach bekannt, beispielsweise aus der DE-C-35 37 722 oder aus dem DE-U-86 08 199. Bei der oben geschilderten Konstruktion eines Steckers bietet es sich an, die Kontaktelemente, die in Teilbereichen hülsen- oder rinnenförmig aus Blech gebogen werden, von einem gemeinsamen Basisbereich her nach oben zu biegen. Die bekannten Stecker dieser Art sind deshalb alle so ausgebildet, daß die offene Seite des Crimpbereiches und die erwähnte Verriegelungskante auf der gleichen Mantelseite des Kontaktelementes, lediglich in Axialrichtung etwas versetzt, ausgebildet sind.Such line plugs are widely known, for example from DE-C-35 37 722 or from DE-U-86 08 199. In the construction of a plug described above, it makes sense to make the contact elements, which are sleeve-shaped or channel-shaped in some areas Sheet metal are bent to bend upwards from a common base area. The known plugs of this type are all designed so that the open side of the crimp area and the mentioned locking edge are formed on the same jacket side of the contact element, only slightly offset in the axial direction.

Beim Ancrimpen eines Litzenleiters kann jedoch der Fall eintreten, daß die Enden der Litze über den Crimpbereich vorstehen und daß dabei die Einzeldrähte der Litze stark aufgespreizt werden. Dann ergibt sich das Problem, daß durch das Einschieben der Verriegelungsleiste, die Teil eines Übergehäuses sein kann, in Querrichtung die Litzenenden über den Gehäuseschlitz in die benachbarte Kontaktkammer geschleift werden und dann einen Kurzschluß mit dem benachbarten Kontakt verursachen.When crimping a stranded conductor, however, the case can occur that the ends of the strand protrude beyond the crimping area and that the individual wires of the strand are greatly expanded. Then there is the problem that by inserting the locking bar, which can be part of an outer housing, the wire ends are dragged in the transverse direction via the housing slot into the adjacent contact chamber and then cause a short circuit with the adjacent contact.

Aufgabe der Erfindung ist es, einen Leitungsstecker der eingangs genannten Art so weiterzubilden, daß trotz gleichbleibender Steckbefestigung der Kontaktelemente und bei ebenfalls gleichbleibender Verriegelung durch eine Verriegelungsleiste bzw. ein Übergehäuse eine sichere Isolierung zwischen benachbarten Kontaktelementen bzw. Leitungsadern gewährleistet wird.The object of the invention is to further develop a line connector of the type mentioned in such a way that, despite the plug connection of the contact elements remaining the same and the locking also remaining constant by means of a locking strip or an outer housing, reliable insulation between adjacent contact elements or line wires is ensured.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Freisparungen bzw. die Verriegelungskanten einerseits und die offenen Seiten der Crimpbereiche andererseits jeweils auf einander entgegengesetzten Mantelseiten der Kontaktelemente vorgesehen sind und daß die Crimpabschnitte der eingesteckten Kontaktelemente jeweils einer geschlossenen Gehäusewand gegenüberliegen.According to the invention, this object is achieved in that the recesses or the locking edges on the one hand and the open sides of the crimping areas on the other are each provided on mutually opposite jacket sides of the contact elements and in that the crimping sections of the inserted contact elements are each opposite a closed housing wall.

Bei der erfindungsgemäßen Steckerkonstruktion sind also die Crimpbereiche von den Verriegelungsbereichen der Kontaktelemente abgewandt, so daß also der Crimpbereich zur Seite der Verriegelungskante und des Gehäuseschlitzes einen mehr oder weniger geschlossenen Blechmantel besitzt und andererseits mit seiner offenen Seite einer geschlossenen Gehäusewand zugekehrt ist. Selbst wenn also ein Litzenleiter an seinem freien Ende aufgespreizt wird und die freien Enden der Einzelleiter unkontrolliert nach außen stehen, können sie keinen Kurzschluß verursachen, da sie einem geschlossenen Wandbereich des Isolierstoffgehäuses gegenüberstehen und jedenfalls mit der quer eingeschobenen Verriegelungsleiste nicht in Berührung kommen.In the connector construction according to the invention, the crimping areas are thus facing away from the locking areas of the contact elements, so that the crimping area on the side of the locking edge and the housing slot has a more or less closed sheet metal jacket and, on the other hand, its open side faces a closed housing wall. Even if a stranded wire is spread open at its free end and the free ends of the individual conductors are uncontrolled to the outside, they cannot cause a short circuit because they face a closed wall area of the insulating material housing and in any case do not come into contact with the transversely inserted locking strip.

Besondere Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Particular refinements and developments of the invention are specified in the subclaims.

Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher erläutert. Es zeigen

  • Figuren 1 und 2 eine erste Ausführungsform eines erfindungsgemäßen Leitungssteckers in zwei Teil-Schnittansichten,
  • Figur 3 eine weitere Ausführungsform eines Leitungssteckers in einer Schnittansicht entsprechend Figur 1,
  • Figuren 4 bis 6 eine Kontaktfeder für den Leitungsstecker von Figur 1 in drei Ansichten und
  • Figuren 7 bis 9 eine Uberfeder für die Kontaktfeder der Figuren 4 bis 6, ebenfalls in drei Ansichten.
The invention is explained in more detail below on the basis of exemplary embodiments. Show it
  • FIGS. 1 and 2 show a first embodiment of a line connector according to the invention in two partial sectional views,
  • FIG. 3 shows a further embodiment of a line connector in a sectional view corresponding to FIG. 1,
  • Figures 4 to 6 a contact spring for the cable connector of Figure 1 in three views
  • Figures 7 to 9 an Uberfeder for the contact spring of Figures 4 to 6, also in three views.

Der in den Figuren 1 und 2 gezeigte Leitungsstecker besitzt ein Gehäuse 1, welches zwei übereinander liegende Reihen von Kontaktkammern 11 aufweist. Die einzelnen Kontaktkammern mit im wesentlichen rechteckigem Querschnitt sind durch eine durchgehende waagerechte Wand 12 sowie durch einzelne senkrechte Wände 13 voneinander getrennt. Nach außen, also zur Oberseite bzw. zur Unterseite hin sind die Kontaktkammern ebenfalls durch Wände 14 geschlossen, wobei diese Wände jedoch Unterbrechungen aufweisen, was später noch im einzelnen beschrieben wird.The line connector shown in FIGS. 1 and 2 has a housing 1 which has two rows of contact chambers 11 lying one above the other. The individual contact chambers with an essentially rectangular cross section are separated from one another by a continuous horizontal wall 12 and by individual vertical walls 13. The contact chambers are also closed by walls 14 towards the outside, that is to say towards the top or bottom, but these walls have interruptions, which will be described in detail later.

In die einzelnen Kontaktkammern ist jeweils ein Kontaktelement 2, wie erwähnt, in Längsrichtung eingesteckt. An jedem Kontaktelement 2 ist dabei im vorderen Bereich eine Rastlanze 41 angeformt, welche in einem Fenster 15 des Gehäuses 1 verrastet ist. Jedes Kontaktelement weist außerdem eine Verriegelungskante 22 auf, die an der zur Außenwand 14 des Gehäuses zugekehrten Mantelseite des Kontaktelementes ausgebildet ist. Im Bereich dieser Verriegelungskanten besitzt das Gehäuse einen Schlitz 16, in welchen eine Verriegelungsleiste 31, welche von der Seite, also quer zur Längsrichtung der Kontaktelemente 2, einschiebbar ist. Im Beispiel der Figur 1 ist die Verriegelungsleiste 31 Teil eines Übergehäuses 3, welches in an sich bekannter Weise das gesamte Gehäuse mit den beiden übereinander liegenden Reihen von Kontaktkammern und Kontaktelementen umfaßt. Die Verriegelungsleiste 31 bietet mit ihrer Abschlußkante 32 einen Anschlag für die erwähnte Verriegelungskante 22 der Kontaktelemente und sichert somit diese zusätzlich gegen ein unerwünschtes Herausziehen aus dem Gehäuse.As mentioned, a contact element 2 is inserted into the individual contact chambers in the longitudinal direction. A latching lance 41 is formed on each contact element 2 in the front area and is latched in a window 15 of the housing 1. Each contact element also has a locking edge 22 which is formed on the jacket side of the contact element facing the outer wall 14 of the housing. In the area of these locking edges, the housing has a slot 16 in which a locking bar 31 can be inserted from the side, that is to say transversely to the longitudinal direction of the contact elements 2. In the example in FIG. 1, the locking bar 31 is part of an overhousing 3 which, in a manner known per se, comprises the entire housing with the two rows of contact chambers and contact elements lying one above the other. The locking bar 31 offers a stop with its end edge 32 for the mentioned locking edge 22 of the contact elements and thus additionally secures them against unwanted pulling out of the housing.

Die Kontaktfeder 2 besitzt an einem Ende (in Figur 1 und 2 am rechten Ende) einen Crimpbereich 29 mit Crimplaschen 23 und Sicherungslaschen 24. In diesen Crimpbereich ist eine als isolierte Litze ausgebildete Ader 5 eines Bandkabels eingeführt. Dabei ist die Ader mit der Isolierung 51 mit den Sicherungslaschen 24 festgeklemmt, während das freie Ende der Ader 5 abisoliert ist, so daß die Einzelleiter 52 blank liegen und durch die umgebogenen Crimplaschen 23 kontaktiert werden.The contact spring 2 has at one end (in FIGS. 1 and 2 at the right end) a crimp area 29 with crimp tabs 23 and securing tabs 24. In this crimp area, a wire 5 of a ribbon cable designed as an insulated strand is inserted. The wire with the insulation 51 is clamped with the securing tabs 24, while the free end of the wire 5 is stripped, so that the individual conductors 52 lie bare and are contacted by the bent crimp tabs 23.

Die freien Enden 52a der Einzelleiter können dabei durchaus über die Crimplaschen 23 vorstehen, ohne daß die Gefahr eines Kurzschlusses mit einem benachbarten Litzenleiter besteht, da die offene Seite des Crimpbereiches im Gehäuse 1 jeweils nach innen zur Wand 12 weist, so daß der freie Raum, in welchen die Enden 52a der Litzenleiter austreten, von drei Seiten durch die Wände 12 und 13 isolierend abgeschlossen ist. Auf jeden Fall können die freien Enden 52a der Litzenleiter nicht durch die Schiebebewegung der Verriegelungsleiste 31 in eine benachbarte Kontaktkammer geschleift werden, da der Schlitz 16 des Gehäuses und die Verriegelungskante 22 der Kontaktelemente sich auf der vom Crimpbereich abgewandten, gegenüberliegenden Mantelseite der Kontaktelemente 2 befinden. Zusätzlich ist der vom Kontaktelement freigestanzte Bereich in Form eines Abdecklappens 25 in dem annähernd hülsenförmigen Kontaktelement 2 nach innen gekröpft und verhindert somit zusätzlich ein Aufspreizen der Litzenenden 52a in den Verschiebebereich der Verriegelungsleiste 31.The free ends 52a of the individual conductors can protrude beyond the crimping tabs 23 without the risk of a short circuit with an adjacent stranded conductor, since the open side of the crimping area in the housing 1 faces inwards towards the wall 12, so that the free space in which the ends 52a of the stranded conductor emerge, is insulated from three sides by the walls 12 and 13. In any case, the free ends 52a of the stranded conductors cannot be dragged into an adjacent contact chamber by the sliding movement of the locking bar 31, since the slot 16 of the housing and the locking edge 22 of the contact elements are located on the opposite jacket side of the contact elements 2 facing away from the crimping area. In addition, the area punched out by the contact element in the form of a cover tab 25 in the approximately sleeve-shaped contact element 2 is cranked inward and thus additionally prevents the strand ends 52a from spreading out into the displacement area of the locking bar 31.

In Figur 3 ist eine etwas abgewandelte Ausführungsform gegenüber Figur 1 gezeigt. Dabei ist ein Gehäuse 101 mit zwei Reihen von Kontaktkammern 111 so ausgebildet, daß die Kontaktkammern jeweils zur Außenseite geschlossene Wände 112 und nach innen durchbrochene Wände 114 aufweisen. In diesen Wänden 114 sind jeweils Fenster 115 zur Aufnahme der Rastlanzen 41 sowie Schlitze 116 zum Einschieben einer Verriegelungsleiste 131 ausgebildet. Diese Verriegelungsleiste 131 ist bei diesem Beispiel als Einzelteil ausgebildet, also nicht Bestandteil eines Übergehäuses. Die Kontaktelemente 102 sind genauso ausgebildet wie die Kontaktelemente 2 in Figur 1; sie sind lediglich gegenüber dieser Figur um 180° gedreht eingesteckt.FIG. 3 shows a somewhat modified embodiment compared to FIG. 1. In this case, a housing 101 is formed with two rows of contact chambers 111 in such a way that the contact chambers each have walls 112 closed to the outside and walls 114 perforated inwards. 114 are in these walls each window 115 for receiving the locking lances 41 and slots 116 for inserting a locking bar 131 formed. This locking bar 131 is formed in this example as a single part, so not part of an outer housing. The contact elements 102 are configured in exactly the same way as the contact elements 2 in FIG. 1; they are only inserted rotated by 180 ° with respect to this figure.

Im folgenden wird noch der Aufbau der Kontaktelemente etwas näher erläutert. Diese Kontaktelemente in Figur 1, 2 oder 3 bestehen jeweils aus einer Kontaktfeder 21 und einer Überfeder 4. Die in den Figuren 4, 5 und 6 in drei verschiedenen Ansichten gezeigte Kontaktfeder 21 ist aus Blech im wesentlichen rinnenförmig gebogen. Dabei sind am Anschlußende die bereits erwähnten Crimplaschen 23 und die Sicherungslaschen 24 ausgebildet. Im Mittelbereich 27 ist die Verriegelungskante 22 freigestanzt, wobei der freigeschnittene Lappen 25 als Abdecklappen nach unten abgekröpft ist. Das dem Anschlußende entgegengesetzte Kontaktende ist zu Steckfedern 26 (in Figur 6 nicht gezeigt) geformt.The structure of the contact elements is explained in more detail below. These contact elements in FIG. 1, 2 or 3 each consist of a contact spring 21 and an over-spring 4. The contact spring 21 shown in FIGS. 4, 5 and 6 in three different views is bent from sheet metal in a substantially channel-shaped manner. The crimp tabs 23 and the securing tabs 24 are formed at the connection end. In the central region 27, the locking edge 22 is punched out, the cut-out tab 25 being bent down as a cover flap. The contact end opposite the connection end is shaped into plug springs 26 (not shown in FIG. 6).

Die in den Figuren 7 bis 9 in den gleichen Ansichten entsprechend der Darstellung der Kontaktfedern in den Figuren 4 bis 6 gezeigte Überfeder 4 ist zu einer Steckhülse mit annähernd rechteckigem Querschnitt gebogen und auf den Kontaktbereich der Kontaktfeder aufgecrimpt. Hierzu dienen die Crimplaschen 42, welche über den Mittelbereich 27 der Kontaktfeder 21 greifen. Aus dieser Überfeder 4 ist die bereits erwähnte Rastlanze 41 nach oben herausgebogen, welche zur Versteifung mit einer Sicke 43 versehen ist.The over-spring 4 shown in FIGS. 7 to 9 in the same views corresponding to the representation of the contact springs in FIGS. 4 to 6 is bent into a plug-in sleeve with an approximately rectangular cross-section and crimped onto the contact area of the contact spring. The crimping tabs 42, which engage over the central region 27 of the contact spring 21, serve this purpose. From this over-spring 4, the locking lance 41 already mentioned is bent upwards, which is provided with a bead 43 for stiffening.
