Clamping contact of an electrical connector, having two contact tonques (13) arranged adjacent to each other, which form a slot (15) between them for the contacting clamping of a conductor, are cut out of the base (5) of the electrical connector, are bent approximately at right angles to the base (5), and abut at the sides against lateral walls (7) of the connector, the slot (15) being slightly narrower than the bare conductor and the contact edges (17) being sharp in order to cut into the insulation of an insulated conductor which is pressed into the slot (15), and a widening being provided in the insertion region of the slot (15), characterised in that the slot (15) which extends between the contact tongues (13) becomes a cut-away portion (14) in the base (5).

Description

Die Erfindung betrifft einen Klemmkontakt mit zwei nebeneinander angeordneten Kontaktzungen, die zwischen sich einen Schlitz zum kontaktierenden Festklemmen eines Leiters bilden, wobei der Schlitz um ein geringes Maß enger bemessen ist als der blanke Leiter und die Kontaktkanten zum Einschneiden der Isolation eines in den Schlitz eingedrückten isolierten Leiters scharf ausgeführt sind, und wobei im Einführbereich des Schlitzes eine Verbreiterung vorgesehen ist.The invention relates to a terminal contact with two side by side contact tongues, which form a slot between them for contacting clamping of a conductor, the slot being dimensioned to a small extent narrower than the bare conductor and the contact edges for cutting the insulation of an insulated that is pressed into the slot Conductor are sharp, and a widening is provided in the insertion region of the slot.

Ein solcher Klemmkontakt ist aus der DE-PS 2 254 318 bekannt. Der Kontaktschenkel mit den beiden Kontaktzungen ist etwa rechtwinklig senkrecht von einer Platinenbasis abgebogen. Nachteilig bei dieser Ausführungsform ist, daß die Kontaktzungen seitlich nicht abgestützt sind, so daß eine Überbiegung oder ein Auseinanderspreizen der Zungen nach der Kontaktierung, z. B. durch die Einwirkung der Leiterummantelung, nicht verhindert werden kann. Ein unkontrolliertes Auseinanderspreizen kann zur Beeinträchtigung der Kontaktierung führen.Such a clamping contact is known from DE-PS 2 254 318. The contact leg with the two contact tongues is bent approximately perpendicularly from a circuit board base. A disadvantage of this embodiment is that the contact tongues are not supported laterally, so that bending or spreading apart of the tongues after contacting, for. B. cannot be prevented by the action of the conductor sheathing. Uncontrolled spreading apart can lead to impaired contact.

Zudem ist aus der DE-AS 2 152 954 ein Verbindungselement zum löt- und abisolierfreien Verbinden von Leitern bekannt, bei dem ein Kabelkamm (Anordnung mehrerer Schlitze bildender Kontaktzungen nebeneinander) aus dem Boden des Verbindungselementes freigeschnitten und etwa rechtwinklig nach oben abgebogen ist, wobei vom Boden rechtwinklig nach oben abgebogene Seitenwände vorgesehen sind, so daß das Verbindungselement im Bereich des Kabelbaums im Querschnitt U-förmig ausgebildet ist und sich der Kabelbaum quer über den Boden erstreckt. Der Kabelbaum dient zum Durchdringen der Isolierung mehrerer nebeneinander angeordneter Leiter und zur Kontaktierung der-Seele der Leiter. Eine seitliche Abstützung für die Kontaktzungen ist ebenfalls nicht vorgesehen.In addition, from DE-AS 2 152 954 a connecting element for soldering and stripping-free connection of conductors is known, in which a cable comb (arrangement of several slots forming contact tongues next to each other) is cut free from the bottom of the connecting element and bent approximately at right angles upwards, from Bottom right-angled upward side walls are provided so that the connecting element in the region of the wire harness is U-shaped in cross section and the wire harness extends across the floor. The cable harness is used to penetrate the insulation of several conductors arranged side by side and to contact the core of the conductor. A lateral support for the contact tongues is also not provided.

Aufgabe der Erfindung ist, einen Klemmkontakt zu schaffen, der im Krallenteil eines elektrischen Verbinders angeordnet ist und eine sichere Kontaktierung gewährleistet.The object of the invention is to provide a clamping contact which is arranged in the claw part of an electrical connector and ensures reliable contacting.

Dsese Aufgabe wird durch die Merkmale der Ansprüche gelöst. Anhand der Zeichnung wird die Erfindung beispielhaft näher erläutert. Es zeigen:

  • Fig. 1 schematisch ein Platinenstück für einen elektrischen Verbinder,
  • Fig. 2 eine Seitenansicht eines elektrischen Verbinders mit Klemmkontakt,
  • Fig. 3 eine Draufsicht auf den elektrischen Verbinder nach Fig. 2,
  • Fig. 4 einen Schnitt längs der Linie IV-IV in Fig. 3,
  • Fig. 5 einen Schnitt längs der Linie V-V. in Fig. 3.
This object is solved by the features of the claims. The invention is explained in more detail by way of example with reference to the drawing. Show it:
  • 1 schematically shows a piece of circuit board for an electrical connector,
  • 2 is a side view of an electrical connector with a clamp contact,
  • 3 is a top view of the electrical connector of FIG. 2;
  • 4 shows a section along the line IV-IV in FIG. 3,
  • Fig. 5 shows a section along the line VV. in Fig. 3.

Der erfindungsgemäße Klemmkontakt 1 ist im Krallenteil 2 eines elektrischen Verbinders angeordnet, wobei der Verbinder Kontaktfederarme 3 oder dergleichen Kontaktelemente und zwischen den Kontaktelementen und dem Krallenteil 2 ein Basisteil 4 besitzen kann.The clamping contact 1 according to the invention is arranged in the claw part 2 of an electrical connector, the connector contact spring arms 3 or the like contact elements and a base part 4 between the contact elements and the claw part 2.

Wesentlich ist, daß der Krallenteil 2 im Querschnitt zumindest U-förmig ausgebildet ist und den Boden 5 sowie die beiden in der Biegelinie 6 rechtwinklig nach oben abgebogenen Seitenwände 7 aufweist.It is essential that the claw part 2 is at least U-shaped in cross-section and has the base 5 and the two side walls 7 bent upwards at right angles in the bending line 6.

Aus dem Boden 5 der Platine ist ein etwa T-förmiger Ausschnitt 8 (Fig. 1) ausgeschnitten, wobei der Querbalken 9 des T-förmigen Ausschnitts sich quer zum Boden 5 und der T-Steg des Ausschnitts 8 sich in der Längsmitte zum Boden 5 erstrecken. Vorzugsweise überragen die beiden seitlichen Endbereiche des Querbalkens 9 die Biegelinie 6 und greifen in die Seitenwände 7 ein. Diese Ausbildung schafft einen Freischnitt für die beiden Einschnitte 11, die sich von den Freischnitten in Längsrichtung der Biegelinie 6 zumindest bis zur quer zum Boden 5 verlaufenden Biegelinie 12 erstrecken. Die Einschnitte 11 schaffen die beiden Kontaktzungen 13, die in der Biegelinie 12 etwa rechtwinklig nach oben abgebogen sind. Die Biegelinie 12 ist zweckmäßigerweise - wie abgebildet - im Abstand vor dem vorzugsweise abgerundeten Endbereich 14 des T-Stegs 10 angeordnet. Diese Maßnahme ermöglicht den Kontaktzungen 13 ein seitliches federndes Ausweichen, ohne daß Teile des Bodens 5 der Federung nennenswerten Widerstand entgegensetzen. Darüber hinaus wird das Abbiegen in der Biegelinie 12 vereinfacht.An approximately T-shaped cutout 8 (FIG. 1) is cut out of the base 5 of the board, the crossbar 9 of the T-shaped cutout extending transversely to the base 5 and the T-web of the cutout 8 extending in the longitudinal center toward the base 5 extend. The two lateral end regions of the crossbar 9 preferably protrude beyond the bending line 6 and engage in the side walls 7. This design creates a free cut for the two incisions 11, which extend from the free cuts in the longitudinal direction of the bending line 6 at least to the bending line 12 running transversely to the bottom 5. The incisions 11 create the two contact tongues 13, which are bent approximately at right angles upwards in the bending line 12. The bending line 12 is expediently - as shown - at a distance from the preferably rounded end region 14 of the T-web 10. This measure enables the contact tongues 13 to deflect laterally without parts of the bottom 5 of the suspension opposing any appreciable resistance. In addition, the turning in the bending line 12 is simplified.

Da die Einschnitte 11 in Längsrichtung der Biegelinien 6 für die Seitenwände 7 verlaufen, können sich die Kontaktzungen 13 seitlich erfindungsgemäß gegen die Seitenwände abstützen, so daß ein Überbiegeschutz geschaffen ist und ein Aufspreizen der Zungen 13, z. B. -durch die Einwirkung des.Isoliermaterials des Leiters, das die Kontaktierung beeinträchtigen könnte, verhindert wird.Since the incisions 11 run in the longitudinal direction of the bending lines 6 for the side walls 7, the Support contact tongues 13 laterally according to the invention against the side walls, so that overbend protection is created and spreading of the tongues 13, e.g. B. - is prevented by the action of the insulating material of the conductor, which could impair the contacting.

Der T-Steg 10 der Aussparung 8 bildet nach dem Hochbiegen der Kontaktzungen 13 den Schlitz 15, in den der Leiterdraht des Leiters geklemmt werden soll. Zweckmäßigerweise geht der Schlitz 15 im oberen Endbereich etwa V-förmig zur Seite auseinander und bildet einen Einführtrichter 16 für das Einlegen des zu kontaktierenden Leiters. Vorzugsweise sind die Schneidkanten 17 der Kontaktzungen 13 im Querschnitt betrachtet winklig geprägt, so daß Schneiden an den Kanten 17 gebildet werden (Fig. 3).After the contact tongues 13 have been bent up, the T-web 10 of the cutout 8 forms the slot 15 into which the conductor wire of the conductor is to be clamped. Advantageously, the slot 15 in the upper end region is approximately V-shaped to the side and forms an insertion funnel 16 for inserting the conductor to be contacted. When viewed in cross section, the cutting edges 17 of the contact tongues 13 are preferably shaped at an angle, so that cutting edges are formed on the edges 17 (FIG. 3).

Nach der Erfindung stützen sich - wie beschrieben - die Kontaktzungen 13 gegen die Seitenwände 7 des Krallenteils 2 ab. Wenn ein isolierter Leiter in den Schlitz 16 eingebracht wird, können die Kontaktzungen 13 wegen der Freisparung 14 seitlich federnd ausweichen. Dabei weichen aber auch die Seitenwandungen 7 seitlich federnd aus und bilden durch ihre Federkraft ein Widerlager für die Kontaktzungen, so daß eine Überbiegung verhindert werden kann. Außerdem sorgt das Widerlager bzw. sorgen die Seitenwände 7 dafür, daß die Isolation, die nach dem Kontaktieren noch eine Spreizkraft auf die Kontaktzungen ausüben kann, die Kontaktierung nicht beeinträchtigt. Insofern wird die Widerlagerkraft der Seitenwände so gewählt, daß sie größer ist als die Spreizwirkung des zu kontaktierenden Leiters.According to the invention - as described - the contact tongues 13 are supported against the side walls 7 of the claw part 2. If an insulated conductor is inserted into the slot 16, the contact tongues 13 can laterally deflect laterally because of the cutout 14. However, the side walls 7 also yield laterally and form an abutment for the contact tongues due to their spring force, so that an overbend can be prevented. In addition, the abutment or the side walls 7 ensure that the insulation, which can still exert a spreading force on the contact tongues after contacting, does not impair the contacting. In this respect, the abutment force of the side walls is chosen so that it is greater than the spreading effect of the conductor to be contacted.

Nach einer besonderen Ausführungsform der Erfindung wird die Widerlagerkraft der Seitenwände 7 durch die Anordnung mindestens einer Sicke 18 vor oder hinter der Kontaktstelle erhöht, wobei sich die Sicke quer zur Längsrichtung des Verbinders über den Boden 5 bis in die Seitenwände 7 erstrecken sollte. Eine derartige, besonders zweckmäßige Sicke 18 ist in den Fig. 2, 3 und 5 abgebildet. Es handelt sich dabei um eine Hochprägung 19 des Bodens nach innen in die U-Form und eine im Querschnitt V-förmige Einwärtsprägung vom freien Endbereich der Seitenwände 7 zur Hochprägung 19 hin, so daß die Schrägwände 20 entstehen (Fig. 5). Eine solche Sickenprägung bringt den besonderen Vorteil, daß die Länge des Verbinders durch das Einziehen der Sicke nicht verkürzt wird.According to a particular embodiment of the invention, the abutment force of the side walls 7 is increased by the arrangement of at least one bead 18 in front of or behind the contact point, the bead should extend across the floor 5 into the side walls 7 transversely to the longitudinal direction of the connector. Such a particularly useful bead 18 is shown in FIGS. 2, 3 and 5. It is an embossing 19 of the bottom inward into the U-shape and a cross-sectionally V-shaped embossing from the free end region of the side walls 7 to the embossing 19, so that the inclined walls 20 are formed (FIG. 5). Such embossing has the particular advantage that the length of the connector is not shortened by the retraction of the bead.

Die Sicke 18 bedingt eine erhebliche Versteifung für die Seitenwände 7 und den Boden 5, so daß eine erhöhte Spreizkraft zum Aufspreizen der Seitenwände aufgewendet werden muß. Auf diese Weise wird das Widerlager für die Kontaktzungen 13 in der gewünschten Weise verstärkt.The bead 18 requires considerable stiffening for the side walls 7 and the bottom 5, so that an increased spreading force must be used to spread the side walls. In this way, the abutment for the contact tongues 13 is reinforced in the desired manner.

Es ist im Zusammenhang mit der Erfindung noch zu vermerken, daß der Erfindungsgedanke im wesentlichen darin zu sehen ist, daß seitliche federnde Stützelemente für die Kontaktzungen 13 geschaffen werden und daß die Basis der Kontaktzungen derart vom Boden 5 freigeschnitten ist, daß die Kontaktzungen ohne nennenswerte Behinderung durch Bodenteile seitlich und federnd ausweichen können. Insofern können auch andere Querschnittsformen, z. B. Kastenformen, für den Krallenteil 2 gewählt werden.It should be noted in connection with the invention that the inventive concept is essentially to be seen in the fact that lateral resilient support elements are created for the contact tongues 13 and that the base of the contact tongues is cut out of the base 5 in such a way that the contact tongues are without any significant impediment can deflect laterally and resiliently through floor parts. In this respect, other cross-sectional shapes, e.g. B. box shapes can be chosen for the claw part 2.
