Abstract

In a multi-core flat cable, the round conductors (2), whose common conductor cross-section is at most 0.25 mm<2>, are arranged in a single plane with a constant distance between one another and are surrounded with a common, extruded insulation (3). The insulation forms a web (4) between in each case two conductors. At least some of the webs are provided, in each case in their centre, with a notch (6) on one or both sides over the complete length of the flat cable. The insulation in each case forms a half-web (5) on both sides of the flat cable. This design of the flat cable ensures that the flat cable can be split with high precision into a plurality of core groups and that, in each split-off core group, the distances of the conductor centres of the individual cores correspond to a predetermined raster, to the extreme limit of the core group. The flat cable, which is provided particularly for wiring purposes in equipments and installations of the electronic industry, is thus particularly suitable for simple plug installation.

Description

1. Anwendungsgebiet der Erfindung1. Field of application of the invention

Die Erfindung liegt auf dem Gebiet der vieladrigen Flachleitungen, wie sie in den Geräten und Anlagen der Elektronik-Industrie für Verdrahtungszwecke eingesetzt werden, und behandelt die konstruktive Ausgestaltung einer solchen Flachleitung im Hinblick auf eine einfache Steckermontage.The invention is in the field of multi-core flat cables, such as those used in the devices and systems of the electronics industry for wiring purposes, and deals with the structural design of such a flat cable with regard to simple plug assembly.

2. Stand der Technik2. State of the art

Bei den für Verdrahtungszwecke entwickelten Flachleitungen ist eine Vielzahl von Rund- oder Flachleitern in einer Ebene nebeneinander angeordnet und von einer gemeinsamen Isolierung umgeben. Diese kann beispielsweise aus zwei miteinander verschweißten Folien bestehen, zwischen denen die Leiter mittels entsprechender Walzen eingebettet werden, oder sie ist mittels eines Extruders aufgebracht (Zeitschrift "Electronic Design, Heft 9, spril 1977, Seite 60 ff., DE-AS 19 42 784). Flachleitun-' gen mit Rundleitern und gemeinsamer extrudierter Isolierung werden dabei mitunter als Stegleitungen ausgebildet, d. h. die Verbindungsstelle der Isolierung zwischen zwei benachbarten Adern hat die Form eines schmalen Steges (DE-AS 10 75 695). Dies gilt insbesondere für Flachleitungen mit geringem Leiterquerschnitt, um bei der Steckermontage die einzelnen Adern voneinander trennen zu können (DE-08 22 43 001). Hinsichtlich der Montage derartiger Flachleitungen wird dabei gefordert, vieladrige Flachleitungen mit beispielsweise 60 Adern am Leitungsende in mehrere Adergruppen aufteilen und die einzelnen Adergruppen jeweils mit einem Stecker versehen zu können. Für eine einfache Steckermontage ist dabei wesentlich, daß die Präzision der Leitungsabmessungen, insbesondere der Leitermittenabstände bzw. das Rastermaß, auch in den Teilstücken erhalten bleibt.In the case of the flat cables developed for wiring purposes, a large number of round or flat conductors are arranged next to one another on one level and surrounded by a common insulation.

3. Darstellung der Erfindung3. Presentation of the invention a) Technische Aufgabea) Technical task

Der Erfindung liegt die Aufgabe zugrunde, eine vieladrige Flachleitung, deren Leiter einen einheitlichen Leiterquerschnitt von höchstens 0,25 mm2 haben, so auszugestalten, daß die Leitungsenden zum Zwecke der Steckermontage leicht in mehrere Adergruppen unterteilt werden können, und zwar derart, daß in jeder abgetrennten Adergruppe die Präzision der Leitungsabmessungen, insbesondere der sogenannte Randabstand, erhalten bleibt.The invention has for its object to design a multi-core flat cable, the conductors of which have a uniform conductor cross section of at most 0.25 mm 2 , in such a way that the cable ends can easily be divided into several core groups for the purpose of plug assembly, in such a way that each severed core group, the precision of the cable dimensions, in particular the so-called edge distance, is retained.

b) Lösung der technischen Aufgabeb) Solution of the technical problem

Zur Lösung dieser Aufgabe geht die Erfindung von einer vieladrigen Flachleitung mit Rundleitern aus, bei der die Leiter in einer einzigen Ebene mit gleichem Abstand zueinander angeordnet und mit einer gemeinsamen, extrudierten Isolierung umgeben sind und bei der die Isolierung zwischen jeweils zwei Leitern einen Steg bildet. Gemäß der Erfindung ist vorgesehen, daß die Flachleitung über ihre ganze Länge mit einer oder mehreren Kerben versehen ist, die sich ein- oder beidseitig in wenigstens einem der Stege jeweils in dessen Mitte befinden, und daß die Isolierung an beiden Seiten der Flachleitung jeweils einen Halbsteg bildet.To achieve this object, the invention is based on a multi-core flat cable with round conductors, in which the conductors are arranged at the same distance from one another in a single plane and are surrounded by a common, extruded insulation, and in which the insulation forms a web between two conductors. According to the invention it is provided that the flat cable is provided over its entire length with one or more notches, which are located on one or both sides in at least one of the webs in the middle thereof, and that the insulation on both sides of the flat cable has a half-web forms.

c) Vorteilec) advantages

Durch eine derartige Ausgestaltung der Flachleitung ist gewährleistet, daß in jeder abgeteilten Adergruppe die Abstände der Leitermitten der einzelnen Adern zur äußeren Begrenzung der Adergruppe einem vorgegebenen Raster entsprechen; da die äußere Degrenzung der Flachleitung

Figure imgb0005
Figure imgb0006
sichere Kontaktgabe gewährleistet. Dies wird die Halbstege an den Seiten der Flachleitung gewährleistet, andererseits durch die Kerben in der Mitte eines Steges. Die Kerben gewährleisten dabei eine leichte und exakte Trennung zweier benachbarter Adern, wobei die entstehenden Adergruppen an beiden Seitenkanten ebenfalls einen Halbsteg aufweisen.Such a configuration of the flat cable ensures that the spacing of the conductor centers of the individual cores to the outer boundary of the core group has a predetermined grid in each divided core group correspond; because the outer boundary of the flat cable
Figure imgb0005
Figure imgb0006
secure contact guaranteed. This is ensured by the half-ridges on the sides of the flat cable, on the other hand by the notches in the middle of a ridge. The notches ensure easy and exact separation of two adjacent wires, with the resulting wire groups also having a half web on both side edges.

Wenn die Art der späteren Aufteilung einer Flachleitung bereits bei der Herstellung der Flachleitung bekannt ist, brauchen die Kerben nur in bestimmten Stegen der Flachleitung vorgesehen zu sein. Für das Montagepersonal entfällt dann die Notwendigkeit des Abzählens bzw. Identifizierens der Teilgruppen bei der Montage, da die Flachleitung vorzugsweise an den Einkerbungen auftrennt, wenn die von Hand ausgeübten Trennkräfte nur näherungsweise im Bereich der Einkerbungen aufgebracht werden. Wenn die spätere Aufteilung der Flachleitung dagegen nicht bekannt ist,- ist es sinnvoll, die Kerben in allen Stegen der Flachleitung vorzusehen. In jedem Fall empfiehlt es sich, mit Hilfe der Kerben den Querschnitt eines Steges um 30 bis 70 % zu schwächen. Dies wird zweckmäßig durch eine beidseitige Kerbung der Stege erreicht.If the type of subsequent division of a flat cable is already known during the manufacture of the flat cable, the notches need only be provided in certain webs of the flat cable. The assembly personnel then no longer need to count or identify the subgroups during assembly, since the flat cable preferably separates at the notches if the separating forces exerted by hand are only applied approximately in the area of the notches. If, on the other hand, the later division of the flat cable is not known, it is advisable to provide the notches in all webs of the flat cable. In any case, it is advisable to use the notches to weaken the cross-section of a web by 30 to 70%. This is expediently achieved by notching the webs on both sides.

d) Ausführungsbeispield) embodiment

Ein Ausführungsbeispiel der neuen Flachleitung ist in den Figuren 1 und 2 dargestellt.An embodiment of the new flat cable is shown in Figures 1 and 2.

Die Flachleitung 1 enthält 20 Rundleiter 2, deren Leiterquerschnitt etwa 0,2 mm2 beträgt und die nebeneinander mit gleichem Abstand in einer Ebene angeordnet sind. Die Rundleiter 2 sind von einer gemeinsamen, extrudierten Isolierung 3 umgeben, wobei diese zwischen den einzelnen Leitern Stege 4 bildet. An jeder Seitenkante der Flachleitung ist ein Halbsteg 5 vorgesehen.The flat cable 1 contains 20 round conductors 2, the conductor cross section of which is approximately 0.2 mm 2 and which are arranged next to one another with the same spacing in one plane. The round conductors 2 are surrounded by a common, extruded insulation 3, which forms webs 4 between the individual conductors. A half web 5 is provided on each side edge of the flat cable.

Bei den Rundleitern 2 handelt es sich um mehrdrähtige Leiter. Der Leitermittenabstand t beträgt beispielsweise 2,54 mm. Der Randabstand des ersten Leiters beträgt t/2, der des zweiten Leiters 3/2 t usw. Die Stege 4 zwischen jeweils zwei Leitern sind genau in der Mitte mit beidseitig angeordneten Kerben 6 versehen, die den Stegquerschnitt um etwa 50 % schwächen. An diesen Kerben lassen sich die einzelnen Adern der Flachleitung bzw. einzelne Adergruppen leicht voneinander trennen. Dadurch ist gewährleistet, daß der Randabstand des nächstliegenden Leiters zu einer Trennstelle stets ebenfalls dem Wert t/2 entspricht.The round conductors 2 are multi-wire conductors. The conductor center distance t is, for example, 2.54 mm. The edge distance of the first conductor is t / 2, that of the second conductor 3/2 t etc. The webs 4 between each two conductors are provided in the middle with notches 6 arranged on both sides, which weaken the web cross section by about 50%. The individual wires of the flat cable or individual wire groups can be easily separated from one another at these notches. This ensures that the edge distance of the closest conductor to a separation point always corresponds to the value t / 2.
