Description

Die Erfindung bezieht sich auf einen elektrischen Verbinder nach dem Oberbegriff des unabhängigen Patentanspruchs 1.The invention relates to an electrical connector according to the preamble of independent claim 1.

In der DE-Patentanmeldung P 40 23 072.4, von der die Erfindung ausgeht, ist ein derartiger elektrischer Verbinder beschrieben, der sich vornehmlich zum Anschluß von Rasterstegleitungen eignet und bei dem das einteilige Gehäuse auf den an dem Verbinderträger verankerten Kontaktelementen unmittelbar verschieblich gelagert ist, wobei jeder Leiter am Kontaktelement im wesentlichen festgeklemmt wird.In DE patent application P 40 23 072.4, from which the invention is based, an electrical connector of this type is described which is primarily suitable for connecting raster cross conductors and in which the one-piece housing is mounted so that it can be moved directly on the contact elements anchored to the connector carrier, whereby each conductor is essentially clamped to the contact element.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, unter Beibehaltung der im wesentlichen durch Klemmung erfolgten Leiterkontaktierung diese auch in Fällen besonderer Leiterbeanspruchung namentlich durch Zugkräfte besonders sicher zu gestalten.Proceeding from this prior art, the invention is based on the object, while maintaining the conductor contact, which is essentially made by clamping, to make it particularly safe even in cases of special conductor stress, particularly by tensile forces.

Die Erfindung löst diese Aufgabe durch die Merkmale des unabhängigen Patentanspruchs 1.The invention solves this problem by the features of independent claim 1.

Der solcherart im wesentlichen formschlüssig mit der Rasterstegleitung korrespondierende Steg wirkt als Zugentlastung, indem auf die Leitung ausgeübte Zugkräfte weitestgehend schon an dem verschiebbaren Teil des Isolierstoffgehäuses abgefangen werden und sich deshalb auf die Kontaktstelle nicht sofort derart auswirken können, daß der Leiter aus ihr herausgezogen wird. Da die Zugentlastung an dem verschiebbaren Teil des Isolierstoffgehäuses angeordnet ist, das in der Leiterklemmstellung mit einem zweiten Teil des Isolierstoffgehäuses oder direkt mit dem Kontaktelement verrastet ist, muß also zunächst diese Verrastung überwunden werden, ehe auf die Klemmzone der Kontaktverbindung selbst nachteilige Kräfte ausgeübt werden.The web, which essentially corresponds to the grid web guide in this way, acts as strain relief in that tensile forces exerted on the line are largely absorbed at the displaceable part of the insulating material housing and therefore cannot immediately affect the contact point in such a way that the conductor is pulled out of it. Since the strain relief is arranged on the displaceable part of the insulating housing, which in the Conductor clamping position with a second part of the insulating material housing or is locked directly with the contact element, this locking must first be overcome before any adverse forces are exerted on the terminal zone of the contact connection itself.

Das Prinzip der Erfindung besteht demzufolge im wesentlichen auch darin, daß man sich die durch die Rastverbindung zwischen den beiden Teilen des Isolierstoffgehäuses bzw. zwischen dem Isolierstoffgehäuse und dem Kontaktelement bestehende Verrastung für eine Zugentlastung zunutze macht.The principle of the invention therefore consists essentially in that one takes advantage of the existing for the strain relief by the latching connection between the two parts of the insulating material housing or between the insulating material housing and the contact element.

Zwar ist es z.B. aus FR-A-2 562 338 grundsätzlich bekannt, an einem Isolierstoffgehäuse eine stoffschlüssig daran angebrachte Zugentlastungsnase vorzusehen, die mit einem Durchbruch einer in das Verbinderteil einzusteckeneden Flachbandleitung als Leiter-Zugentlastung zusammenwirkt. Im Unterschied zum Gegenstand der Erfindung ist dort allerdings das Isolierstoffgehäuse nicht zum Verbinderträger oder zu den Kontaktelementen relativ verschieblich angeordnet. Zudem ist die Nase an einer unter ständiger Riegel- oder Eingriffsspannung stehenden Lasche angeformt. Diese Lasche ist nicht klappbar am Gehäuse angelenkt, sondern lediglich entgegen der ihr innewohnenden Federkraft durch Auswärtsbiegen aus der Riegelposition ausschwenkbar, womit sich der Leiter bei Bedarf wieder aus dem Gehäuseteil entfernen läßt.Although it is e.g. from FR-A-2 562 338 it is generally known to provide an isolating housing with a cohesively attached strain relief lug which interacts with a breakthrough of a ribbon cable to be inserted into the connector part as a conductor strain relief. In contrast to the subject matter of the invention, however, the insulating housing is not arranged to be relatively displaceable relative to the connector carrier or to the contact elements. In addition, the nose is molded onto a tab that is under constant locking or engagement tension. This tab is not hinged to the housing, but can only be swung out against the inherent spring force by bending it outward from the locking position, so that the conductor can be removed from the housing part if necessary.

Auf einen elektrischen Verbinder derjenigen Art, von der die Erfindung ausgeht, also auf einen Verbinder mit einem relativ zum Kontakt bzw. zum Verbinderträger verschieblich angeordnetem Gehäuse(teil), ist diese Anordnung nicht ohne weiteres übertragbar. Denn würde man die bekannte Anordnung wie in FR-A-2 562 338 beschrieben übernehmen, wäre die ständig in Riegelstellung strebende Nase beim Einstecken des Leiters in den Kontakt, wobei sich das Gehäuse in verbinderträgerferner Einstellung befindet, im Weg und würde folglich die Montagearbeiten und die notwendigen Relativbewegungen der Teile behindern. Andererseits kann die bekannte Anordnung nicht gewährleisten, daß die Verbindung auch in Fällen besonderer Leiterbeanspruchung im Sinne einer Leiterabbiegung nach auswärts in Richtung zum Verbinderträger noch zuverlässig wirkt.An electrical connector of the type from which the invention is based, that is to say a connector with a housing (part) which is displaceable relative to the contact or to the connector carrier, this arrangement is not readily transferable. Because if one were to adopt the known arrangement as described in FR-A-2 562 338, the nose which constantly strives in the locking position when the conductor is inserted into the contact, the housing being in the position remote from the connector carrier, would get in the way and would consequently result in the assembly work and hinder the necessary relative movements of the parts. On the other hand, the known arrangement cannot ensure that the connection still acts reliably even in cases of special conductor stress in the sense of a conductor deflection outwards in the direction of the connector carrier.

Demgegenüber ist es entsprechend der Erfindung möglich, den hakenförmigen Steg bereits in die seiner späteren Wirkstellung entsprechende Lage zum Leiter hineinzuklappen, bevor das Isolierstoffgehäuseteil in seine Endstellung verbracht wird. Während dieser Bewegung fängt sich der Haken im Durchbruch des Leiters endgültig und vervollständigt die zugfeste Verbindung während der Verschiebung des Isolierstoffteils. In dessen Endlage sorgt der abgewinkelte Schenkel des Hakens zudem auch dafür, daß der Leiter selbst bei seitlichem Abbiegen sicher gehalten ist.In contrast, according to the invention it is possible to fold the hook-shaped web into the position corresponding to its later operative position relative to the conductor before the insulating housing part is brought into its end position. During this movement, the hook finally catches in the opening in the conductor and completes the tensile connection during the displacement of the insulating part. In its end position, the angled leg of the hook also ensures that the conductor is held securely even when turning sideways.

Ein der wesentlicher Unterschied zum Stand der Technik besteht also insbesondere darin, daß der zugentlastende Steg nicht (erst) in der endgültigen Zuordnung des Leiters zum Isolierstoffgehäuse in einen kleinen Durchbruch selbsttätig einrastet, sondern bereits in einer Vormontagestellung in einen langlochartigen Durchbruch eingeklappt wird. Erst dadurch wird es möglich, eine wirksame Zugentlastung bei einem mit verschieblichem Isolierstoffgehäuse(teil) auf einfache Weise zu realisieren. Zu dieser Lehre aber leistet FR-A-2 562 338 keinen Beitrag.One of the main differences from the prior art is, in particular, that the strain relief web does not (automatically) snap into a small opening in the final assignment of the conductor to the insulating housing, but already is folded into a slot-like opening in a pre-assembly position. This is the only way to achieve effective strain relief in a simple manner with a sliding insulating housing (part). However, FR-A-2 562 338 makes no contribution to this teaching.

  • Fig. 2 eine Seitenansicht in Richtung des Ansichtspfeiles II der Fig. 1,
  • Fig. 3 eine Aufsicht auf den Verbinder nach Fig. 1 entsprechend dem Ansichtspfeil III in Fig. 2,
  • Fig. 4 den Verbinder nach Fig. 1 mit angeschlossenem Leiter und
  • Fig. 5 und 6 schaubildliche Darstellungen des Verbinders vor und nach dem Anschluß einer Rasterstegleitung.
Further advantageous refinements are specified in the subclaims. Otherwise, the invention is best understood from the following description of an embodiment shown in the drawings. The drawings show - in each case on a considerably enlarged scale -:
  • 1 shows a longitudinal section through an electrical connector on a printed circuit board with a conductor not yet connected,
  • 2 is a side view in the direction of the arrow II of FIG. 1,
  • 3 is a plan view of the connector of FIG. 1 according to the arrow III in Fig. 2,
  • Fig. 4 shows the connector of FIG. 1 with a connected conductor and
  • 5 and 6 are diagrammatic representations of the connector before and after the connection of a grid bar line.

Der in seiner Gesamtheit mit 10 bezeichnete elektrische Verbinder weist ein Isolierstoffgehäuse 11 und eine der Polzahl entsprechende Anzahl von Kontaktelementen 12 auf. Wie die Fig. 2 und 3 sowie 5 und 6 zeigen, sind die jeweils gleichgearteten Kontaktelemente 12 parallel hintereinander im Isolierstoffgehäuse 11 angeordnet.The electrical connector, designated as a whole by 10, has an insulating material housing 11 and a number of contact elements 12 corresponding to the number of poles. As FIGS. 2 and 3 and 5 and 6 show, the contact elements 12 of the same type are arranged in parallel in the insulating housing 11.

Jedes Kontaktelement 12 ist im wesentlichen gabelförmig ausgebildet und weist einen Anschlußschenkel 13 zur Befestigung an einem Verbinderträger 14 auf. Üblicherweise handelt es sich - wie dargestellt - bei dem Anschlußschenkel 13 um ein Lötbeinchen des Kontaktelements 12 und bei dem Verbinderträger 14 um eine Leiterplatte.Each contact element 12 is essentially fork-shaped and has a connecting leg 13 for attachment to a connector carrier 14. Usually, as shown, the connecting leg 13 is a solder leg of the contact element 12 and the connector carrier 14 is a printed circuit board.

Betrachtet man den Anschlußschenkel 13 als Stiel einer Gabel, bildet ein Gabelschenkel einen in der Zeichnungsebene der Fig. 1 federelastisch beweglichen Klemmschenkel 15 aus. Der zweite Gabelschenkel dient als Lagerabschnitt 16 zur Halterung und beweglichen Führung des Isolierstoffgehäuses 11. Dieser Lagerabschnitt 16 ist in sich selbst wieder gabelartig gestaltet; er besitzt die beiden Gabelschenkel 17 und 18, von denen beim Ausführungsbeispiel der Gabelschenkel 18 bezüglich des gegenüberliegenden Gabelschenkels 17 federelastisch ausgebildet ist. Der Gabelschenkel 18 weist eine Rastmulde 19 auf und die zugekehrte Innenwand des Isolierstoffgehäuses 11 einen entsprechenden Rastnocken 20, die in gegenseitigem Eingriff die verbinderträgernahe Einstellung des Isolierstoffgehäuses 11 bezüglich des Kontaktelementes 12 lösbar arretieren (siehe Fig. 4). Eine weitere Rastmulde 19′ am Gabelschenkel 18 dient der vorübergehenden Arretierung der verbinderträgerfernen Einstellung des Isolierstoffgehäuses 11 bezüglich des Kontaktelementes 12 entsprechend Fig. 1.If the connecting leg 13 is regarded as the handle of a fork, a fork leg forms a clamping leg 15 which is resiliently movable in the plane of the drawing in FIG. 1. The second fork leg serves as a bearing section 16 for holding and movably guiding the insulating-material housing 11. This bearing section 16 is again fork-like in design; it has the two fork legs 17 and 18, of which, in the exemplary embodiment, the fork leg 18 with respect of the opposite fork leg 17 is resilient. The fork leg 18 has a locking recess 19 and the facing inner wall of the insulating material housing 11 has a corresponding locking cam 20 which, in mutual engagement, detachably lock the setting of the insulating material housing 11 near the connector carrier with respect to the contact element 12 (see FIG. 4). Another locking recess 19 'on the fork leg 18 is used for the temporary locking of the connector carrier remote setting of the insulating material 11 with respect to the contact element 12 corresponding to FIG. 1st

Im Bereich des Klemmschenkels 15 ist unterhalb der isolierstoffgehäuseseitigen Leitereinstecköffnung 25 eine Klemmzone K ausgebildet, innerhalb der das durch die Öffnung 25 eingesteckte abisolierte Ende 26 eines elektrischen Leiters 27 gegen eine Klemmnase 24 des Klemmschenkels 15 drückt und den Klemmschenkel 15 entgegen seiner Federrückstellkraft nach außen drückt. Der Klemmnase 24 gegenüberliegend befindet sich im Isolierstoffgehäuse 11 ein Klemmwiderlagerabschnitt 31. Hier ist der eingesteckte Leiter 26, wie es Fig. 4 veranschaulicht, kontaktgebend festgehalten.In the region of the clamping leg 15, a clamping zone K is formed below the conductor insertion opening 25 on the insulating material housing side, within which the stripped end 26 of an electrical conductor 27 inserted through the opening 25 presses against a clamping lug 24 of the clamping leg 15 and presses the clamping leg 15 against its spring restoring force to the outside. A clamping abutment section 31 is located opposite the clamping nose 24 in the insulating material housing 11. Here, the inserted conductor 26, as illustrated in FIG. 4, is held in contact.

Geht man davon aus, daß die Klemmnase 24 scharf ist und ein wenig in das Material des abisolierten Leiterendes 26 eintritt, läßt sich der Leiter 27 nicht ohne weiteres wieder aus der recht stabilen Verbindung herausziehen. Um aber zusätzliche Sicherheit gegenüber auf den Leiter 27 ausgeübten Zugkräften zu erhalten, ist an dem Isolierstoffgehäuse 11 eine besondere Zugentlastung 28 vorgesehen.If one assumes that the clamping lug 24 is sharp and enters the material of the stripped conductor end 26 a little, the conductor 27 cannot easily be pulled out of the rather stable connection again. However, in order to obtain additional security against tensile forces exerted on conductor 27, a special strain relief 28 is provided on the insulating material housing 11.

Beim Ausführungsbeispiel ist in Verlängerung einer Außenwand 29 des Isolierstoffgehäuses 11 eine Platte oder Lasche 30 vorgesehen, die mit der Gehäusewand 29 über ein Filmscharnier 32 einstückig und werkstoffeinheitlich sowie schwenkbar verbunden ist. An ihrer zur Ebene der Leitereinstecköffnungen 25 weisenden Seite trägt die Lasche 30 mehrere Stege 34 in Gestalt zweischenkliger Haken, deren an der Lasche 30 angebundener Schenkel 35 zum Querdurchgriff durch und dessen daran anschließender hakenförmig abgewinkelter Schenkel 36 zum Hintergriff hinter einen Durchbruch 37 bestimmt ist, der in zugeordneten Isolierstoffbrücken 33 der Rasterstegleitung 27 angebracht ist.In the exemplary embodiment, a plate or tab 30 is provided in the extension of an outer wall 29 of the insulating material housing 11, which is connected to the housing wall 29 in one piece and in a material-uniform and pivotable manner via a film hinge 32. On its side facing the level of the conductor insertion openings 25, the tab 30 carries a plurality of webs 34 in the form of two-legged hooks, the legs 35 of which are connected to the tab 30 for transverse penetration and the adjoining hook-shaped angled legs 36 for the rear engagement behind an opening 37 which is attached in associated insulating material bridges 33 of the grid web line 27.

Wenn das Isolierstoffgehäuse 11 in der verbinderträgerfernen Position entsprechend Fig. 1 befindlich ist, wird der Leiter 27 mit seinen abisolierten Enden 26 durch die Leitereinstecköffnungen 25 in die spätere Klemmzone K eingeführt. Dabei ist zunächst die Lasche 30 nach auswärts gerichtet (vgl. gestrichelte Linienführung in Fig. 1). Sodann klappt man die Lasche 30 gegen die Rasterstegleitung 27, wobei die Stege 34 durch die Durchbrüche 37 in den Isolierstoffbrücken 33 zunächst frei hindurchgreifen (Fig. 1).1, the conductor 27 is inserted with its stripped ends 26 through the conductor insertion openings 25 into the later clamping zone K. First, the tab 30 is directed outward (see dashed lines in Fig. 1). The tab 30 is then folded against the grid web line 27, the webs 34 initially reaching freely through the openings 37 in the insulating material bridges 33 (FIG. 1).

Wenn nun das Isolierstoffgehäuse 11 relativ zu den ortsfesten Kontaktelementen und in Relativbewegung zu dem Leiter 27 gegen die Leiterplatte 14 geschoben wird, greift der Hakenschenkel 36 des Steges 34 hinter die untere Begrenzung 33′ des jeweiligen Durchbruchs 37. Dadurch wird die Lasche 30 in ihrer bestimmungsgemäßen Position nach Fig. 4 bzw. Fig. 6 gehalten, die dadurch gekennzeichnet ist, daß die Rasterstegleitung 27 durch Anlage des unteren Randes des Durchbruches 37 an der Unterseite des Stegschenkels 35 an das Isolierstoffgehäuse 11 gefesselt ist.If the insulating material housing 11 is now pushed relative to the stationary contact elements and in relative movement to the conductor 27 against the printed circuit board 14, the hook leg 36 of the web 34 engages behind the lower limit 33 'of the respective opening 37. As a result, the tab 30 is held in its intended position according to Fig. 4 or Fig. 6, which is characterized in that the raster web line 27 by contacting the lower edge of the opening 37 on the underside of Web leg 35 is tied to the insulating material housing 11.

Wirken Zugkräfte an der Leitung 27, werden diese insoweit und zumindest solange vom Isolierstoffgehäuse 11 aufgefangen, ohne sich der Klemmzone K mitzuteilen, solange diese Kräfte nicht die Rückhaltekräfte der Rastverbindung 19/20 übersteigen.If tensile forces act on the line 27, they will be absorbed to this extent and at least as long by the insulating housing 11 without communicating the clamping zone K, as long as these forces do not exceed the retaining forces of the latching connection 19/20.

Der hakenartige Übergriff des Stegschenkels 36 über den unteren Rand des Durchbruchs 37 hält die Rasterstegleitung 27 im übrigen auch dann an der Lasche 30 fest, wenn sie von dieser weg abgebogen verlaufen sollte.The hook-like overlap of the web leg 36 over the lower edge of the opening 37 also holds the grid web line 27 to the tab 30 when it should be bent away from it.
