Abstract

A distributor unit for use in tele-communication applications has a series of spring contact elements (1) arranged in a line and located in a block (4). The side arms (7) of the U-shaped elements have slotted sections that cut through the insulation of connection wires (2). The centre section is formed in a tight, closed U-section that exerts high contact pressure against the inserted pin (3) of a switch unit. The pin locates in a formed guideway (6). USE/ADVANTAGE - Telephone exchange m.d.f. Provides good contact for h.v. overload.

Description

Die Erfindung bezieht sich auf eine Verteilerleiste für Tele­ kommunikations-, insbesondere Fernsprechanlagen mit aneinander gereihten Kontaktteilen, die Anschlußelemente für ankommende und Anschlußelemente für abgehende Leitungen tragen und die Kontakt­ federn aufweisen, die mit Kontaktzungen eines Schutzsteckers steckverbindbar sind. Eine derartige Verteilerleiste ist zum Beispiel durch das deutsche Gebrauchsmuster 87 16 917 bekannt ge­ worden. Danach weist eine Verteilerleiste ein U-förmig gebogenes Kontaktteil auf, das an beiden Enden die als Schneidklemmen aus­ gebildeten Anschlußelemente trägt. Aus der Basis des Kontakt­ teils sind entlang seiner Längskanten aus entgegengesetzter Richtung lappenartig zwei Kontaktfedern abgerissen und in die Richtung der Seitenschenkel abgebogen. Sie bilden an ihren frei­ en Enden eine Kontaktstelle zum Anschalten eines Schutzsteckers.The invention relates to a distribution strip for telephoto communication, especially telephone systems with each other Arranged contact parts, the connection elements for incoming and Wear connection elements for outgoing lines and the contact have springs with contact tongues of a protective plug are pluggable. Such a distribution strip is for Example known from the German utility model 87 16 917 ge been. Then a distributor strip has a U-shaped curve Contact part on that at both ends as insulation displacement terminals formed connecting elements carries. Based on the contact some are opposite along its long edges Torn two tabs in the direction of the flap and into the Turned towards the side legs. They make free at theirs ends of a contact point for connecting a protective plug.

Der Schutzstecker ist üblicherweise mit Überspannungsableitern bestückt, die hohe Überspannungen gegen Erde ableiten. In Län­ dern mit einem hohen Anteil von Erdleitungen sind die maximalen Überspannungen in der Regel auf 220 V begrenzt. Der erforderli­ che Kontaktdruck kann von den vorhandenen Kontaktfedern ohne weiteres aufgebracht werden. Aufgrund der begrenzten Breite der Kontaktfedern kann aber der Kontaktdruck nicht so stark erhöht werden, daß durch Blitzschlag erzeugte Überströme in Ländern mit einem hohen Anteil an Freileitungen sicher abgeleitet werden können.The protective plug is usually with surge arresters equipped with high surge voltages against earth. In Län those with a high proportion of underground lines are the maximum Overvoltages are usually limited to 220 V. The required che contact pressure can of the existing contact springs without further be applied. Due to the limited width of the However, contact springs cannot increase the contact pressure as much be that overcurrents generated by lightning in countries with a high proportion of overhead lines can be safely derived can.

Der Erfindung liegt die Aufgabe zugrunde, den Kontaktdruck der Kontaktfeder zu erhöhen.The invention has for its object the contact pressure Increase contact spring.

Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst. Die Kontaktfeder erreicht nun die volle Breite des Kontaktteils, so daß bereits dadurch die Kontaktkraft erhöht wird. Durch die schlaufenförmige Ausbildung des Basisabschnitts addieren sich die Federkräfte der beiden Schenkel der Ausbiegung zu noch höherer Kontaktkraft.This object is achieved by the invention according to claim 1. The contact spring now reaches the full width of the contact part, so that the contact force is already increased. Through the loop-shaped formation of the base section add up  the spring forces of the two legs of the deflection are still too higher contact force.

Nach einer Weiterbildung der Erfindung weist die Kontaktfeder an ihrem freien Ende zur Steckzunge hin einen Vorsprung in Form einer Aufweitung auf. Dadurch wird die genaue Lage der Kontaktstelle am federnden Ende definiert.According to a development of the invention, the contact spring a projection at its free end towards the tongue Form of an expansion on. This will determine the exact location of the Contact point defined at the resilient end.

Nach einer anderen Weiterbildung der Erfindung ist die Kontakt­ feder leicht schräg zur Steckrichtung geneigt. Dadurch steht das freie Ende der Kontaktfeder näher zur Steckzunge, so daß eine genaue Lagedefinition der Kontaktzone gegeben ist. Diese Lösung läßt sich fertigungstechnisch einfacher verwirklichen.According to another development of the invention, the contact spring slightly inclined to the direction of insertion. This means the free end of the contact spring closer to the tongue, so that an exact location definition of the contact zone is given. These Solution is easier to implement in terms of production technology.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.In the following the invention based on one in the drawing illustrated embodiment explained in more detail.

Die Fig. 1 und 2 zeigen schematisiert einen Schnitt und eine Draufsicht einer Verteilerleiste mit Kontaktteilen 1, ankommen­ den und abgehenden Leitungen 2 und Steckzungen 3 eines nicht näher dargestellten Schutzsteckers. Durch strichpunktierte Linien ist ein Isolierstoffkörper 4 angedeutet, der die Kontakt­ teile 1 aufnimmt. Diese sind aus einem langen schmalen Zuschnitt im wesentlichen U-förmig gebogen und an den Enden der Seiten­ schenkel als Anschlußelemente 7 in Form von Schneidklemmen aus­ gebildet, an die die Leitungen 2 angeschlossen sind. Figs. 1 and 2 show schematically a section and a plan view of a distribution bar with contact parts 1, arrive to and outgoing cables 2 and 3 a protective plug tabs, not shown. By dash-dotted lines, an insulating body 4 is indicated, which receives the contact parts 1 . These are bent from a long narrow blank substantially U-shaped and formed at the ends of the sides as connecting elements 7 in the form of insulation displacement connectors to which the lines 2 are connected.

Das Gehäuse 4 ist mit Stecköffnungen 6 für die Steckzungen 3 versehen. Die Basis des Kontaktteils 1 ist schlaufenförmig in diese Richtung ausgebogen und bildet mit dieser Schlaufe eine Kontaktfeder 5, die an ihrem freien Ende mit der Steckzunge 3 kontaktierbar ist. Die Kontaktfeder 4 ist leicht schräg zur Steckrichtung geneigt, so daß ihre Kontaktstelle in der Nähe ihres freien Endes liegt. In das offene Ende der Ausbiegung ragt ein Fixieransatz 8 des Gehäuses 1 hinein. Dieser legt das Fuß­ ende der Kontaktfeder 5 im Gehäuse 4 fest.The housing 4 is provided with plug openings 6 for the tongues 3 . The base of the contact part 1 is bent out in a loop shape in this direction and forms with this loop a contact spring 5 which can be contacted with the tongue 3 at its free end. The contact spring 4 is inclined slightly obliquely to the direction of insertion, so that its contact point is close to its free end. A fixing projection 8 of the housing 1 projects into the open end of the bend. This defines the foot end of the contact spring 5 in the housing 4 .
