Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer elektrisch leitenden Verbindung zwischen einem in Isoliermaterial eingebetteten elektrischen Flachleiter und einem weiterführenden elektrischen Leiter, unter Verwendung eines metallischen Kontaktteils mit Durchstechkrallen an einem Ende und einem in Richtung des anderen Endes verlaufenden Steg, mit welchem das Kontaktteil mittels der Durchstechkrallen unter Durchdringung des Isoliermaterials am Flachleiter festgelegt wird und mit welchem am freien Ende des Kontaktteils der weiterführende Leiter angeschlossen wird.The invention relates to a method for producing an electrically conductive connection between an electrical flat conductor embedded in insulating material and a further electrical conductor, using a metallic contact part with piercing claws at one end and a web running in the direction of the other end, with which the contact part is determined by means of the piercing claws while penetrating the insulating material on the flat conductor and with which the further conductor is connected to the free end of the contact part.

Ein solches Verfahren ist aus den Dokumenten US-A-4 371 225 und US-A-3 691 509 bekannt.Such a method is known from documents US-A-4 371 225 and US-A-3 691 509.

Kontaktteile mit Durchstechkrallen sind auf dem Markt erhältlich. Sie werden in der abisolierfreien Anschlußtechnik eingesetzt, und zwar unabhängig von der Querschnittsform des Leiters. Diese Kontaktteile haben den Vorteil, daß das oft aufwendige Abisolieren entfällt. Die Durchstechkrallen müssen bei Einsatz dieser Kontaktteile nicht nur das Isoliermaterial des Leiters durchdringen. Sie müssen vielmehr insbesondere auf Dauer einen guten, festen Kontakt mit dem Leiter selbst haben. Aus diesem Grunde werden die Kontaktteile mit erheblicher Kraft am Leiter festgelegt, wodurch dessen Isoliermaterial von den Durchstechkrallen fest umschlossen bzw. eingepreßt wird. Das kann sich bei Flachleitern nachteilig auswirken, da einerseits das relativ dünne Leitermaterial von den Durchstechkrallen leicht beschädigt werden kann und weil andererseits das umschlossene Isoliermaterial schon nach relativ kurzer Zeit zu fließen beginnt. Der Sitz des Kontaktteils am Flachleiter wird dadurch gelockert und es kommt zu Fehl- bzw. Wackelkontakten. Eine solche Verbindungsstelle muß dann erneuert oder zumindest aufwendig nachbearbeitet werden.Piercing claw contact parts are available on the market. They are used in the stripping-free connection technology, regardless of the cross-sectional shape of the conductor. These contact parts have the advantage that the often complex stripping is not necessary. The piercing claws not only have to penetrate the insulating material of the conductor when using these contact parts. Rather, they must have good, firm contact with the leader himself, especially in the long term. For this reason, the contact parts are fixed to the conductor with considerable force, as a result of which the insulating material is firmly enclosed or pressed in by the piercing claws. That can happen with Flat conductors have an adverse effect, since on the one hand the relatively thin conductor material can be easily damaged by the piercing claws and on the other hand because the enclosed insulating material begins to flow after a relatively short time. This loosens the contact of the contact part on the flat conductor and leads to faulty or loose contacts. Such a connection point must then be renewed or at least elaborately reworked.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, durch das bei Verwendung eines Kontaktteils mit Durchstechkrallen zum Kontaktieren eines Flachleiters die Gefahr einer Beschädigung desselben verhindert und eine einwandfreie elektrische Verbindung auf Dauer gewährleistet sind.The invention has for its object to provide a method by which, when using a contact part with piercing claws for contacting a flat conductor, the risk of damage to the same is prevented and a perfect electrical connection is ensured in the long run.

Diese Aufgabe wird bei einem Verfahren der eingangs geschilderten Art gemäß der Erfindung dadurch gelöst,

  • daß der Flachleiter zunächst an seinem Ende abisoliert wird,
  • daß danach das Kontaktteil mit seinen Durchstechkrallen an einem von Isoliermaterial umgebenen Teil des Flachleiters festgelegt wird und
  • daß schließlich das abisolierte Ende des Flachleiters mit dem Steg des Kontaktteils elektrisch leitend verbunden wird.
This object is achieved in a method of the type described at the outset according to the invention in that
  • that the flat conductor is first stripped at its end,
  • that after that the contact part with its piercing claws is fixed to a part of the flat conductor surrounded by insulating material and
  • that finally the stripped end of the flat conductor is electrically conductively connected to the web of the contact part.

Mit diesem Verfahren wird das Kontaktteil wie in bisheriger Technik mittels der Durchstechkrallen am isolierten Flachleiter festgelegt. Das kann aber mit relativ niedrigem Druck geschehen, da die Durchstechkrallen für die elektrisch leitende Verbindung nicht benötigt werden. Diese Verbindung wird vielmehr über das abisolierte Ende des Flachleiters hergestellt, das mit dem Steg des Kontaktteils beispielsweise verlötet oder verschweißt wird. Die Verbindungsstelle ist durch die vorher am isolierten Teil des Flachleiters festgelegten Durchstechkrallen vor Zugbelastungen geschützt. Es ist auf diese Weise eine dauerhaft gute elektrisch leitende Verbindung zwischen dem Flachleiter und dem Kontaktteil hergestellt. Der feste Sitz des Kontaktteils am Flachleiter bleibt auch erhalten, da das Isoliermaterial nicht von den Durchstechkrallen eingequetscht ist. Es fließt daher nicht aus der Haltestelle ab. Wegen des geringen Drucks, mit dem die Durchstechkrallen angebracht werden, ist außerdem die Gefahr einer Beschädigung des Flachleiters vermieden.With this method, the contact part is fixed to the insulated flat conductor using the piercing claws, as in previous technology. However, this can be done at a relatively low pressure, since the piercing claws are not required for the electrically conductive connection. Rather, this connection is made via the stripped end of the flat conductor, which is soldered or welded to the web of the contact part, for example. The connection point is through the piercing claws previously fixed on the insulated part of the flat conductor are protected against tensile loads. In this way, a permanently good electrically conductive connection is established between the flat conductor and the contact part. The tight fit of the contact part on the flat conductor is also retained since the insulating material is not pinched by the piercing claws. It therefore does not flow out of the stop. Because of the low pressure with which the piercing claws are attached, the risk of damage to the flat conductor is also avoided.

Das in Fig. 1 dargestellte Kontaktteil 1 besteht aus einem elektrisch gut leitenden verformbaren Metall, beispielsweise aus einer Kupferlegierung. Es weist an seinem einen Ende Durchstechkrallen 2 und an seinem anderen Ende einen beliebig gestalteten Befestigungsteil auf, der im dargestellten Ausführungsbeispiel als Hülse 3 ausgeführt ist. Es könnte aber beispielsweise auch ein U-förmiges Befestigungsteil vorhanden sein. Zwischen Durchstechkrallen 2 und Hülse 3 befindet sich ein dieselben verbindender Steg 4.The contact part 1 shown in Fig. 1 consists of an electrically highly conductive deformable metal, for example of a copper alloy. It has piercing claws 2 at one end and an attachment part of any design at its other end, which in the exemplary embodiment shown is designed as a sleeve 3. However, a U-shaped fastening part could also be present, for example. A web 4 connecting the same is located between piercing claws 2 and sleeve 3.

Das Kontaktteil 1 soll zur elektrisch leitenden Verbindung eines isolierten Flachleiters 5 und eines weiterführenden Leiters verwendet werden, der im dargestellten Ausführungsbeispiel als runder, isolierter Litzenleiter 6 ausgeführt ist. Diese Verbindung wird beispielsweise wie folgt hergestellt:
Der Flachleiter 5 wird an seinem Ende abisoliert. Danach wird das Kontaktteil 1 mittels seiner Durchstechkrallen 2 am Flachleiter 5 so festgelegt, daß die Durchstechkrallen 2 die Isolierung desselben durchdringen. Das wird mit relativ niedrigem Druck durchgeführt, der nur ausreichen muß, um die Durchstechkrallen 2 durch die Isolierung des Flachleiters 5 durchzudrücken und so weit zu verformen, daß sich ein fester Halt ergibt. Die Enden der Durchstechkrallen 2 können dabei auch bis zur Berührung mit dem Flachleiter 5 verformt werden, allerdings nur bis zu seiner Oberfläche, ohne Durchdringung desselben.The contact part 1 is to be used for the electrically conductive connection of an insulated flat conductor 5 and a further conductor, which in the exemplary embodiment shown is designed as a round, insulated stranded conductor 6. This connection is established, for example, as follows:
The flat conductor 5 is stripped at its end. Then the contact part 1 is fixed by means of its piercing claws 2 on the flat conductor 5 so that the piercing claws 2 penetrate the insulation thereof. This is carried out at a relatively low pressure, which only has to be sufficient to push the piercing claws 2 through the insulation of the flat conductor 5 and to deform them to such an extent that there is a firm hold. The ends of the piercing claws 2 can also be deformed until they come into contact with the flat conductor 5, but only up to its surface, without penetration thereof.

Das aus der Isolierung herausragende Ende des Flachleiters 5 liegt dann am Steg 4 des Kontaktteils 1. Es kann dort an der Verbindungsstelle 7 mit dem Steg 4 verlötet oder verschweißt werden. Der abisolierte Flachleiter 5 kann für ein Verlöten vor dem Festlegen der Durchstechkrallen 2 verzinnt werden. Es reicht dann eine Erwärmung zum Verlöten mit dem Steg 4 aus. Danach kann am freien Ende des Kontaktteils 1 ein beliebiger isolierter elektrischer Leiter als weiterführender Leiter in beliebiger Weise festgelegt werden.The end of the flat conductor 5 protruding from the insulation then lies on the web 4 of the contact part 1. It can be soldered or welded to the web 4 at the connection point 7. The stripped flat conductor 5 can be tinned for soldering before the piercing claws 2 are fixed. It is then sufficient to heat it up with the web 4. Thereafter, at the free end of the contact part 1, any insulated electrical conductor can be defined in any manner as a continuing conductor.

Wenn als weiterführender Leiter ein Litzenleiter 6 verwendet wird, dann wird auf denselben zweckmäßig nach dem Abisolieren zuerst ein Lötmittel aufgetragen. Das Kontaktteil 1 kann dann mittels seiner Hülse 3 am Litzenleiter 6 beispielsweise durch Quetschen festgelegt werden. Durch Wärmezufuhr beim oder nach dem Quetschen wird das Lötmittel verflüssigt und Hülse 3 und Litzenleiter 6 werden so zusätzlich miteinander verlötet.If a stranded conductor 6 is used as a further conductor, then a solder is expediently applied to it after stripping. The contact part 1 can then be fixed by means of its sleeve 3 on the stranded conductor 6, for example by squeezing. By applying heat during or after the squeezing, the solder is liquefied and sleeve 3 and Stranded conductors 6 are additionally soldered to one another.

Um die ganze Verbindungsstelle kann abschließend noch ein Schutzkörper 8 herumgespritzt werden, der in Fig. 3 durch eine strichpunktierte Linie angedeutet ist. Durch den Schutzkörper 8 wird der feste Sitz des Kontaktteils 1 am Flachleiter 5 unterstützt. Die ganze Verbindungsstelle ist dadurch außerdem feuchtigkeitsdicht umschlossen.Finally, a protective body 8 can be sprayed around the entire connection point, which is indicated in FIG. 3 by a dash-dotted line. The tight fit of the contact part 1 on the flat conductor 5 is supported by the protective body 8. The entire connection point is also enclosed in a moisture-tight manner.

Das geschilderte Verfahren ist für das Durchverbinden von Einzelleitern geeignet. Es kann aber auch für Flachleiter-Bandleitungen eingesetzt werden, in denen zwei oder mehr Flachleiter 5 nebeneinander angeordnet sind. Eine solche aus zwei Flachleitern 5 bestehende Bandleitung ist in Fig. 4 gestrichelt angedeutet. Jeder einzelne Flachleiter 5 wird dann mit dem beschriebenen Verfahren mit einem weiterführenden Leiter verbunden.The described method is suitable for connecting single conductors. However, it can also be used for flat conductor ribbon cables in which two or more flat conductors 5 are arranged next to one another. Such a ribbon cable consisting of two flat conductors 5 is indicated by dashed lines in FIG. 4. Each individual flat conductor 5 is then connected to a further conductor using the method described.
