To increase the contact reliability, the two spring legs are offset with respect to one another so that the actual clamping point is subject to an additional torsional force (p). <IMAGE>

Description

Die Erfindung betrifft.eine Anschlußklemme zum abisolierfreien Anschluß elektrischer Leiter in Verteilern von Fernmeldeanlagen, insbesondere Fernsprechvermittlungsanlagen, bestehend aus zwei in Längsrichtung ge- trennter und an ihrem einen Ende starr miteinander verbundenen Federschenkeln, welche einen Klemmbereich für den elektrischen Leiter und ein zwischen Klemmbereich und der starren Verbindung der beiden Federschenkel verlaufendes Langloch begrenzen, wobei die Anschlußklemme einstückig aus einem metallischen Bandmaterial hergestellt ist und die Federschenkel im Klemmbereich durch Scheren getrennt sind.The invention betrifft.eine terminal for insulation displacement connection of electrical conductors in distributors of telecommunication installations, particularly telephone exchanges, comprising two ge in the longitudinal direction - severed and at its one end rigidly interconnected spring limbs which a clamping region for the electrical conductor and between the clamping area and the limit the rigid connection of the two spring legs extending elongated hole, the terminal is made in one piece from a metallic band material and the spring legs are separated in the clamping area by scissors.

Eine derartige Anschlußklemme ist z.B. aus der DE-AS 12 32 232 bekannt. Aufgrund ihres Aufbaus ist eine Anschlußklemme dieser Art einfach herzustellen. Nachteilig ist jedoch, daß eine so aufgebaute Anschlußklemme die in der Praxis häufig geforderten hohen Anforderungen an die Kontaktsicherheit nicht erfüllt.Such a terminal is e.g. known from DE-AS 12 32 232. Because of its structure, a terminal of this type is easy to manufacture. It is disadvantageous, however, that a connection terminal constructed in this way does not meet the high requirements for contact reliability which are often required in practice.

Aufgabe der vorliegenden Erfindung ist es, eine Anschlußklemme der eingangs genannten Art so zu verbessern, daß bei einfacher Herstellung der Anschlußklemme gleichzeitig die hohen Anforderungen an die Kontaktsicherheit erfüllt sind.The object of the present invention is to improve a connection terminal of the type mentioned in the introduction in such a way that, with simple production of the connection terminal, the high requirements for contact reliability are met at the same time.

Diese Aufgabe wird dadurch gelöst, daß die Federschenkel um eine senkrecht zur Längsrichtung in der Ebene der Anschlußklemme verlaufende Biegekante derart gegeneinander verschränkt sind, daß die Federschenkel am äußeren Ende des Klemmbereichs um ein vorgegebenes Maß zueinander versetzt sind.This object is achieved in that the spring legs are mutually intertwined around a bending edge running perpendicular to the longitudinal direction in the plane of the connecting terminal in such a way that the spring legs are offset from one another by a predetermined amount at the outer end of the clamping region.

Durch die Verschränkung der beiden Federschenkel erfüllt die erfindungsgemäße Anschlußklemme bei einfacher und billiger Herstellung auch hohe Anforderungen bezuglich der Kontaktsicherheit. Bei der Einführung eines Drahtes schneiden die Federschenkel in den Draht und werden so in dieser Lage fixiert. Die beim Einschneiden entstehenden Kerben liegen aufgrund der Verschränkung der beiden Federschenkel um einen geringen Abstand versetzt.-Wird nun der Draht weiter nach unten in seine endgültige Position geschoben verdrehen sich die Federschenkel, so daß eine zusätzliche Torsionskraft auftritt, welche die Kontakteigenschaften der erfindungsgemäßen Anschlußklemme wesentlich verbessert.By interlocking the two spring legs, the connecting terminal according to the invention also meets high requirements in terms of contact reliability with simple and inexpensive manufacture. When a wire is inserted, the spring legs cut into the wire and are thus fixed in this position. The notches created during the cutting are offset by a small distance due to the entanglement of the two spring legs. If the wire is pushed further down into its final position, the spring legs twist, so that an additional torsional force occurs, which significantly affects the contact properties of the terminal according to the invention improved.

Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Anschlußklemme ergeben sich aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung von Ausführungsbeispielen.Further advantageous embodiments of the connecting terminal according to the invention result from the subclaims and from the following description of exemplary embodiments.

Bei der in Fig. 1 und Fig. 2 dargestellten Einfach-Anschlußklemme 1 handelt es sich um ein einfaches Stanzteil aus dünnem Bandmaterial mit einfachen Außenkonturen, welche von den geraden Außenkanten der Federschenkel und dem Klemmeneinlauf 5 gebildet sind. Der eigentliche Klemmbereich zwischen den Klemmbacken 3 und 4 wird vom Klemmeneinlauf 5 eineseits und einem Langloch 2 andererseits begrenzt. Dieser Klemmbereich wird mittels eines einfachen Trennschnitts hergestellt. Dabei geschieht das Durchreißen der Verbindung zwischen den beiden Klemmbacken 3 und 4 in Form einer Verschränkung, die für die Funktion der erfindungsgemäßen Anschlußklemme bestimmend ist. Aufgrund dieser Verschränkung sind die Abisolierkanten 6 und 7 der Klemmbäcken 3 und 4 an ihren dem Klemmeneinlauf 5 zugewandten Enden um den Abstand a voneinander entfernt.The single connecting terminal 1 shown in FIGS. 1 and 2 is a simple stamped part made of thin strip material with simple outer contours, which are formed by the straight outer edges of the spring legs and the terminal inlet 5. The actual clamping area between the jaws 3 and 4 is limited by the clamp inlet 5 on the one hand and an elongated hole 2 on the other. This clamping area is produced using a simple separating cut. The connection between the two clamping jaws 3 and 4 is torn through in the form of an entanglement which is decisive for the function of the connecting terminal according to the invention. Because of this entanglement, the stripping edges 6 and 7 of the clamping jaws 3 and 4 are separated from one another by the distance a at their ends facing the terminal inlet 5.

Fig. 3 zeigt eine Doppel-Anschlußklemme gemäß der vorliegenden Erfindung zum Anschluß zweier isolierter elektrischer Leiter. Diese Doppel-Anschlußklemme 8 wird im Prinzip wie die in Fig. 1 und Fig. 2 beschriebene Einfach-Anschlußklemme hergestellt, jedoch sind hier zwei Trennschnitte pro Klemme erforderlich. Zwischen die beiden Klemmbacken 10 und 11 ragt eine-Zunge 9 hinein, die an ihrem unfreien Ende mit den unfreien Enden der beiden Klemmbacken 10 und 11 starr miteinander verbunden ist. Die Doppel-Anschluß- . klemme weist zwei Langlöcher 12 und 13 sowie zwei Klemmeneinläufe 14 und 15 auf, zwischen denen sich die jeweiligen Klemmbereiche befinden. Die beiden Abisolierkanten eines Klemmbereichs werden dabei jeweils von einer Kante einer der Klemmbacken 10 und 11, sowie von einer Kante der Zunge 9 gebildet. Auch bei dieser Ausführungsform der erfindungsgemäßen Anschlußklemme sind die Abisolierkanten der beiden Klemmbereiche an ihren dem jeweiligen Klemmeneinlauf zugewandten Ende um den Abstand a voneinander entfernt.Fig. 3 shows a double terminal according to the present invention for connecting two insulated electrical conductors. In principle, this double connecting terminal 8 is produced like the single connecting terminal described in FIGS. 1 and 2, but two separating cuts per terminal are required here. A tongue 9 protrudes between the two clamping jaws 10 and 11 and is rigidly connected to one another at its unfree end by the unfree ends of the two jaws 10 and 11. The double connection. clamp has two slots 12 and 13 and two clamp inlets 14 and 15, between which the respective clamping areas are located. The two Stripping edges of a clamping area are each formed by an edge of one of the clamping jaws 10 and 11 and by an edge of the tongue 9. In this embodiment of the connecting terminal according to the invention, the stripping edges of the two clamping regions are at a distance a from one another at their end facing the respective terminal inlet.

Anhand der Fig. 4 bis 1Z soll im folgenden die Wirkungsweise der Anschlußklemme gemäß der Erfindung beschrieben werden. Dabei sind in den Fig. 4,6,8 und 10 jeweils eine Vorderansicht der Anschlußklemme 1 und in den Fig. 5,7,9 und 11 eine Draufsicht der Anschlußklemme 1, bzw. Schnitte durch die Anschlußklemme 11 in Höhe des elektrischen Leiters dargestellt, während Fig. 17. eine Seitenansicht der Anschlußklemme nach Einführung eines elektrischen Leiters zeigt.The operation of the terminal according to the invention will be described below with reference to FIGS. 4 to 1Z. 4,6,8 and 10 each show a front view of the connection terminal 1 and in FIGS. 5,7,9 and 11 a top view of the connection terminal 1, or sections through the connection terminal 11 at the level of the electrical conductor while Fig. 17 shows a side view of the terminal after insertion of an electrical conductor.

Durch die bei der Anschlußklemme 1 gewählte Abschrägung des Klemmeneinlaufs 5 drückt der eingeführte elektrische Leiter 14 die Anschlußklemme 1 etwas auf, bevor der elektrische Leiter 14 mit seiner Isolation 15 die Abisolierkanten 6 und 7 erreicht (siehe Fig. 4). Wenn der elektrische Leiter 14 zwischen die Abisolierkanten 6 und 7 gedrückt wird (siehe Fig. 6 bis 9), so schneiden die Abisolierkanten in den Draht 16 und fixieren die beiden Klemmbacken 3 und 4 in dieser Lage. Da die Klemmbacken 3 und 4 beim Stanzvorgang - wie vorhergehend ausgeführt wurde - gegeneinander verschränkt worden sind, liegen die beiden durch die Abisolierkanten 6 und 7 im Draht 16 hevorgerufenen Kerben um den Abstand a versetzt.Due to the beveling of the terminal inlet 5 selected for the terminal 1, the introduced electrical conductor 14 presses the terminal 1 slightly before the electrical conductor 14 with its insulation 15 reaches the stripping edges 6 and 7 (see FIG. 4). When the electrical conductor 14 is pressed between the stripping edges 6 and 7 (see FIGS. 6 to 9), the stripping edges cut into the wire 16 and fix the two clamping jaws 3 and 4 in this position. Since the clamping jaws 3 and 4 have been entangled with one another during the punching process - as explained above - the two notches caused by the stripping edges 6 and 7 in the wire 16 are offset by the distance a.

Wird nun der elektrische Leiter 14 entlang den Abisolierkanten 6 und 7, die durch die Kerben im Draht 16 in diesen Draht 16 fixiert sind, in seine endgültige Position im Klemmbereich, d.h. bis kurz vor das Langloch 2, gedrückt (siehe Fig. 10 bis 12), verstärkt sich der Kontaktdruck der beiden Klemmbacken 3 und 4 auf den Draht 16, da sich der Abstand zwischen elektrischem Leiter 14 und dem geschlossenen unteren Ende des Langloches verringert hat.Now the electrical conductor 14 along the stripping edges 6 and 7, which are fixed by the notches in the wire 16 in this wire 16, pressed into its final position in the clamping area, ie until just before the elongated hole 2 (see FIGS. 10 to 12), the contact pressure of the two increases Jaws 3 and 4 on the wire 16 because the distance between the electrical conductor 14 and the closed lower end of the elongated hole has decreased.

Durch die Einführung des elektrischen Leiters 14 in die Anschlußklemme 1 werden die Abisolierkanten 6 und 7 aufgrund der starren Verbindung der beiden Klemmbacken 3 und 4 unterhalb des Langlochs 2 seitlich ausgelenkt.. Gleichzeitig wird aufgrund der vorgegebenen Verschränkung zwischen den Abisolierkanten 6 und 7, bezogen auf die Ebene der Anschlußklemme 1, eine der Abisolierkanten 6 und 7 nach vorne ausgelenkt, während die andere der beiden Abisolierkanten 6 und 7 nach hinten ausgelenkt wird. Dadurch entsteht ein in einem bestimmten Winkel zur Ebene der Anschlußklemme 1 verlaufender von den Abisolierkanten 6 und 7 begrenzter keilförmiger Spalt der sich zum Klemmeneinlauf 5 hin verbreitert. Dieser Spalt bewirkt eine Verdrehung der beiden Klemmbacken 3 und 4, so daß auf die Klemmbacken 3 und 4 eine zusätzliche Torsionskraft p ausgeübt wird. An den Kerben im Draht 16 werden dadurch zusätzliche Grade aufgeworfen, die außen eine zusätzliche Kontaktfläche bilden.By introducing the electrical conductor 14 into the terminal 1, the stripping edges 6 and 7 are laterally deflected due to the rigid connection of the two clamping jaws 3 and 4 below the elongated hole 2 the level of the terminal 1, one of the stripping edges 6 and 7 deflected to the front, while the other of the two stripping edges 6 and 7 is deflected to the rear. This creates a wedge-shaped gap which is limited by the stripping edges 6 and 7 and runs at a certain angle to the level of the terminal 1 and widens towards the terminal inlet 5. This gap causes a twisting of the two jaws 3 and 4, so that an additional torsional force p is exerted on the jaws 3 and 4. As a result, additional grades are raised on the notches in the wire 16, which form an additional contact surface on the outside.

Durch das Aufspreitzen der Federschenkel können die Kontaktflächen, welche mittels eines Trennschnitts gebildet werden, galvanisch mit Kontaktwerkstoffen z.B. Ag oder Sn versehen werden. Die erfindungsgemäßen Einfach-Anschlußklemmen bzw. Doppel-Anschlußklemmen dienen - an der Basis verlängert - als Trenn- oder Schaltfedern in Verteilerbauteilen.By spreading the spring legs, the contact surfaces, which are formed by means of a separating cut, can be galvanically provided with contact materials, for example Ag or Sn. The single connection terminals or double connection terminals according to the invention serve - extended at the base - as isolating or switching springs in distributor components.
