Abstract

An electrical connector is shown and described for the connection of electrical conductors, especially grid web lines, which are arranged parallel to one another, are connected to insulating material links and have an insulating material housing for a number of contact elements corresponding to the number of pins, which contact elements in each case have at least one connecting limb which can be anchored firmly on a connector support such as a circuit board, at least a part of the insulating material housing being capable of being displaced from a first position, corresponding to the conductor insertion point, to a second position, corresponding to the conductor connection point, which is protected for example by latching. In order to design the clamping of the contact connector to be less sensitive to tension forces on the conductor, a tension-relief device is provided in such a manner that at least one web is arranged externally on the moving part of the insulating material housing, which web extends with respect to the connector support on the side of the housing pointing away from the connector support transversely to the movement direction of the insulating material housing part, passes through a corresponding perforation in the insulating material link of the conductor, at least in the conductor connection point of the insulating material housing, and thus ties the conductor down on the insulating material housing. <IMAGE>

Description

Die Erfindung bezieht sich auf einen elektrischen Verbinder zum Anschluß von parallel zueinander angeordneten, mit Isolierstoffbrücken verbundenen elektrischen Leitern, insbesondere Rasterstegleitungen, mit einem Isolierstoffgehäuse für eine der Polzahl entsprechende Anzahl von Kontaktelementen, die jeweils mindestens einen Anschlußschenkel aufweisen, der an einem Verbinderträger wie Schaltungsplatte fest verankerbar ist, wobei wenigstens ein Teil des Isolierstoffgehäuses von einer ersten, der Leitereinführstellung entsprechenden, in eine - etwa durch Verrastung - gesicherte zweite, der Leiteranschlußstellung entsprechenden, Einstellung verschiebbar ist.The invention relates to an electrical connector for connecting parallel to each other, connected with insulating bridges electrical conductors, in particular grid ridges, with an insulating housing for a number of contacts corresponding to the number of poles, each having at least one connecting leg, which is fixed to a connector carrier such as a circuit board can be anchored, at least part of the insulating material housing being displaceable from a first setting corresponding to the conductor insertion position into a second setting corresponding to the conductor connection position, which is secured, for example by latching.

Ein elektrischer Verbinder dieser Art ist beispielsweise aus der EP-PS 0 203 097 bekanntgeworden. Dort ist ein zweiteiliges Insolierstoffgehäuse vorgeschlagen, dessen Unterteil die Kontaktelemente lagert und von diesen auf dem Verbinderträger festgehalten wird, wenn sie an der Schaltungsplatte angelötet sind. Ein Oberteil des Isolierstoffgehäuses ist als mit dem Unterteil verrastbarer Verschlußdeckel ausgebildet, der zugleich eine den Leiter an den Anschlußschenkel einer Kontaktfeder drückenden Ansatz aufweist und somit den Leiter klemmschlüssig im Kontaktbereich hält. Bei dem Leiter handelt es sich um ein elastisches Flachkabel.An electrical connector of this type has become known, for example, from EP-PS 0 203 097. There, a two-part insulator housing is proposed, the lower part of which supports the contact elements and is held by them on the connector carrier when they are soldered to the circuit board. An upper part of the insulating material housing is designed as a closure cover which can be locked with the lower part and which at the same time has an attachment which presses the conductor onto the connecting leg of a contact spring and thus holds the conductor in the contact area in a clamped manner. The conductor is an elastic flat cable.

In der DE-Patentanmeldung P 40 23 072.4 ist ein 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. Auch hier wird jeder Leiter am Kontaktelement im wesentlichen festgeklemmt.In DE patent application P 40 23 072.4, an electrical connector is described which is primarily suitable for the connection of raster web cables and in which the one-piece housing is mounted directly displaceably on the contact elements anchored to the connector carrier. Again, each conductor is essentially clamped onto 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 im wesentlichen und in erster Linie dadurch, daß außen an dem verschieblichen Teil des Isolierstoffgehäuses mindestens ein sich an dessen von dem Verbinderträger wegweisenden Seite quer zur Verschieberichtung des Isolierstoffgehäuseteils bezüglich des Verbinderträgers erstreckender Steg angeordnet ist, der mindestens in der Leiteranschlußstellung des Isolierstoffgehäuses einen korrespondierenden Durchbruch in einer Isolierstoffbrücke des Leiters durchgreift und somit den Leiter an das Isolierstoffgehäuse fesselt.The invention solves this problem essentially and primarily by the fact that on the outside of the movable part of the insulating material housing there is at least one web extending on its side facing away from the connector carrier transversely to the direction of displacement of the insulating material part with respect to the connector carrier, which is at least in the conductor connection position of the Isolierstoffgehäuses penetrates a corresponding opening in an insulating material bridge of the conductor and thus ties the conductor to the insulating material housing.

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. 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 web, which essentially corresponds to the grid web cable in this way, acts as a strain relief in that tensile forces exerted on the line are largely absorbed on 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. Because the strain relief on the sliding part of the insulating housing is arranged, which is locked in the conductor clamping position with a second part of the insulating housing or directly with the contact element, so this locking must first be overcome before adverse forces are exerted on the terminal zone of the contact connection itself. The principle of the invention therefore consists essentially in the fact that one makes use of the existing for the strain relief by the latching connection between the two parts of the insulating housing or between the insulating housing and the contact element for strain relief.

Weitere vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Prinzips sind in den Unteransprüchen angegeben. Im übrigen versteht sich die Erfindung am besten anhand der nachfolgenden Beschreibung eines in den Zeichnungen dargestellten Ausführungsbeispiels.

Further advantageous refinements and developments of the principle according to the invention 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,

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 in its entirety by 10, has an insulating material housing 11 and a number of contact elements 12 corresponding to the number of poles. As shown in FIGS. 2 and 3 and 5 and 6, the contact elements 12 of the same type are arranged in parallel one behind the other 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 close to the connector carrier with respect to the contact element 12 (see FIG. 4). Another locking recess 19 ′ on the fork leg 18 serves to temporarily lock the setting of the insulating material housing 11 remote from the connector carrier with respect to the contact element 12 according to FIG. 1.

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 area 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 lug 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 plate 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).When the insulating housing 11 is in the position remote from the connector carrier, as shown in FIG. 1, the stripped ends 26 of the conductor 27 are inserted through the conductor insertion openings 25 into the later clamping zone K. The tab 30 is initially 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 against the printed circuit board 14 relative to the stationary contact elements and in relative movement to the conductor 27, 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 grid web line 27 by contacting the lower edge of the opening 37 on the underside of the 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 snap-in 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 overlapping 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.
