Abstract

The sandwich or laminated distributor includes wafer-type contact elements (2) of the distributor (1) which are provided with flat approx. fully elongated contact parts (7) mutually strung together and designed as paired mutually contacting contact springs within the contact elements (2) and as insulation piecing connection devices (i.p.c.d.) (8) at their outermost emits for connection of the incoming and outgoing lines. The contact element has two separate part-housings (5,6) with an inner housing (5) extending into an outer housing (6) with the contact parts (7) retained between the part-housings and fixed against lengthwise displacement by abutments (13) in recesses (12). The inner housing (5) includes a recess (12) in the form of a cylindrical depression with a corresp. cylindrical ridged protruberance (13) forming an abutment at this point and jutting into the recess (12). ADVANTAGE - Advanced housing design with good access to individual surfaces within housing.

Description

Die Erfindung bezieht sich auf einen Schichtverteiler für eine Telekommunikations-, insbesondere Fernsprechanlage, wobei schei­ benartige Kontaktbauteile des Schichtverteilers übereinander stapelbar sind.The invention relates to a layer distributor for a Telecommunications, in particular telephone system, where shi benike contact components of the layer distributor on top of each other are stackable.

Ein derartiges Kontaktbauteil ist z.B. durch die AS-25 18 832 bekannt geworden. Danach ist das Kontaktbauteil mit flachen und annähernd gestreckt verlaufenden Kontaktteilen versehen, die im Inneren des Kontaktbauteils als paarweise miteinander kontak­ tierbare Kontaktfedern und an ihren äußeren Enden als Schneid­ klemmen zum Anschluß von ankommenden und abgehenden Leitungen ausgebildet sind. Das Kontaktbauteil weist ein Gehäuse auf, das aus zwei Teilgehäusen zusammengesetzt ist. Dabei ragt ein vor­ deres Gehäuseinnenteil teilweise in ein rückseitiges Gehäuse­ außenteil hinein. Die Kontaktteile sind zwischen den Teilge­ häusen gehalten. Das Innengehäuse weist einen nasenartigen Vor­ sprung 2 auf, der in ein Zentrierloch des Kontaktteils hinein­ ragt und dieses gegen Längsverschiebung sichert.Such a contact component is known for example from AS-25 18 832. Thereafter, the contact member is provided with flat and approximately elongated contact parts, which are formed in the interior of the contact member as a pair of contactable contact springs and clamp at their outer ends as a cutting for connecting incoming and outgoing lines. The contact component has a housing which is composed of two part housings. In this case, a front part of the inner housing partially protrudes into a rear housing outer part. The contact parts are kept between the Teilge housings. The inner housing has a nose-like jump before 2 , which protrudes into a centering hole of the contact part and secures it against longitudinal displacement.

Das Gehäuseinnenteil ist so ausgebildet, daß die Einzelflächen relativ gut zugänglich sind und daß die Entformungsrichtung des Spritzwerkzeugs senkrecht zur flachen Außenseite liegt.The housing inner part is designed so that the individual surfaces are relatively accessible and that the direction of removal of the injection mold is perpendicular to the flat outside.

Der Erfindung liegt die Aufgabe zugrunde, räumlich komplexere Gehäuseformen zu ermöglichen.The invention has for its object spatially more complex To enable housing shapes.

Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst. Durch die Ausgestaltung der Vertiefung als Einsenkung im Innen­ gehäuse ist es möglich, diese Form mit Hilfe von Schiebernadeln im Spritzgußwerkzeug zu erzeugen. Das bedeutet, daß die Entfor­ mungsrichtung in der Ebene der scheibenartigen Gehäuseteile lie­ gen kann. Dies ermöglicht Hinterschneidungen im Gehäuse, durch die z.B. die bedienungsseitig angeordneten Schneidklemmen zum Berührungsschutz weitgehend überdeckt werden können.This object is achieved by the invention according to claim 1. By designing the recess as a depression in the inside It is possible to make this shape with the help of pusher needles to produce in the injection mold. This means that the Entfor direction in the plane of the disc-like housing parts lie  can. This enables undercuts in the housing e.g. the insulation displacement terminals arranged on the operator side for Protection against contact can be largely covered.

Eine derartige Weiterbildung der Erfindung ist im Anspruch 2 gekennzeichnet. Der nach hinten offene Aufnahmeschlitz wird nach dem Zusammenfügen mit dem Außengehäuse durch dieses Ver­ schlossen, so daß die Schneidklemmen nahezu vollständig um­ schlossen sind.Such a development of the invention is in claim 2 featured. The opening slot, which is open to the rear after assembling with the outer case by this ver closed so that the insulation displacement terminals almost completely are closed.

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

Nach den Fig. 1, 2 und 3 sind in einem Schichtverteiler 1 scheibenartige Kontaktbauteile 2 und flache scheibenförmige Drahtführungen 3 abwechselnd in einem Trägerteil 4 übereinander gestapelt. Das Kontaktbauteil 2 besteht aus einem Innengehäuse 5, einem Außengehäuse 6 und Kontaktteilen 7. Die Kontaktteile 7 sind auf der Bedienungsseite des Schichtverteilers 1 als Schneid­ klemmen 8 zum Anschluß von Schaltdrähten ausgebildet. Im Inne­ ren des Schichtverteilers 1 enden sie in Kontaktfedern 9, die jeweils paarweise über einen Trennkontakt 10 miteinander ver­ bunden sind. Dieser kann durch Einstecken eines Steckers 11 unterbrochen werden.According to Fig. 1, 2 and 3, disc-like contact components 2, and flat disk-shaped wire guides 3 are alternately stacked one above the other in a supporting member 4 in a distributor 1 layer. The contact component 2 consists of an inner housing 5 , an outer housing 6 and contact parts 7 . The contact parts 7 are on the operating side of the layer distributor 1 as insulation displacement clamps 8 for connecting jumper wires. In the interior of the layer distributor 1 , they end in contact springs 9 , each of which is connected to one another in pairs via a disconnecting contact 10 . This can be interrupted by inserting a plug 11 .

Das Innengehäuse 5 ist weitgehend vom Außengehäuse 6 überdeckt. Die Kontaktteile 7 sind zwischen den beiden Gehäuseteilen ge­ halten. Dabei weist das Innengehäuse 5 eine Vertiefung 12 in Form einer zylindrischen Einsenkung auf. Diese Einsenkung wird durch eine verschiebbare Nadel eines Spritzgußwerkzeuges er­ zeugt. Das Kontaktteil 7 weist an dieser Stelle eine entspre­ chende zylindrische nasenartige Ausprägung 13 auf, die in die Vertiefung 12 hineinragt. Durch dieses Ineinandergreifen wird verhindert, daß die Kontaktteile 7 beim Eindrücken eines Schalt­ drahts verschoben werden können.The inner housing 5 is largely covered by the outer housing 6 . The contact parts 7 are between the two housing parts hold ge. The inner housing 5 has a recess 12 in the form of a cylindrical depression. This depression is generated by a movable needle of an injection molding tool. The contact part 7 has at this point a corre sponding cylindrical nose-like expression 13 which protrudes into the recess 12 . This interlocking prevents the contact parts 7 can be shifted wire when pressing a switch.

Die frontseitigen Schneidklemmen 8 ragen in zur Rückseite hin offene Aufnahmekammern 14 des Innengehäuses 5 hinein. Sie wer­ den von Außenwänden 15 der Aufnahmekammern 14 weitgehend über­ deckt. Um diesen Aufnahmeschlitz in Spritzguß herstellen zu können, muß die Entformungsrichtung der Werkzeuge mit der Ge­ häuseebene übereinstimmen. Dies wird dadurch ermöglicht, daß die Vertiefungen 12 mit Hilfe von senkrecht zur Entformungs­ richtung beweglichen Schiebernadeln erzeugt werden.The insulation displacement connectors 8 on the front protrude into receiving chambers 14 of the inner housing 5 that are open toward the rear. You who largely covers the outer walls 15 of the receiving chambers 14 . In order to be able to produce this receiving slot in injection molding, the direction of demoulding of the tools must match the plane of the housing. This is made possible by the fact that the depressions 12 are produced with the aid of sliding needles which are movable perpendicularly to the demolding direction.
