Abstract

A method is specified for producing an electrically conductive connection between a flat conductor stripline and a cable which passes on from there, each of which has at least two electrical conductors. For stress relief of the junction points, the ends of the stripline and cable are initially inserted, with the conductors stripped of insulation and in the correct orientation, into a carrier which is provided with suitable depressions and consists of insulating material. Thereafter, the conductors to be connected through of the stripline and cable are soldered to one another. Finally, a cover which is firmly connected to the carrier and consists of insulating material is injection moulded onto the junction points of the conductors and onto the ends of the strip line and cable. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer elektrisch leitenden Verbindung zwischen einer Flachleiter-Bandleitung und einer weiterführenden Leitung, die jeweils mindestens zwei elektrische Leiter aufweisen, mit welchem die Leiter der beiden Leitungen zunächst abisoliert und danach elektrisch leitend miteinander verbunden werden und mit welchem die Verbindungsstelle der beiden Leitungen in einen Schutzkörper aus Isoliermaterial eingebettet wird (DE-OS 39 12 139).The invention relates to a method for producing an electrically conductive connection between a flat conductor ribbon cable and a further line, each having at least two electrical conductors, with which the conductors of the two lines are first stripped and then electrically conductively connected to one another and with which the junction of the two lines is embedded in a protective body made of insulating material (DE-OS 39 12 139).

Verfahren zum Verbinden von elektrischen Leitungen sind in unterschiedlichsten Ausführungsformen seit Jahren bekannt. Probleme treten dabei kaum auf, wenn es sich bei den Leitern der zu verbindenden Leitungen um stabile Leiter handelt. Wenn die zu verbindenden Leiter der einen Leitung entsprechend der eingangs erwähnten DE-OS 39 12 139 Flachleiter mit der üblichen geringen Dicke sind, ergeben sich jedoch erhebliche Schwierigkeiten, da solche Flachleiter mechanisch sehr empfindlich sind und leicht brechen können. Das macht sich insbesondere nach dem elektrisch leitenden Verbinden der Flachleiter mit stabilen Leitern der weiterführenden Leitung störend bemerkbar, wenn die dabei hergestellte Verbindungsstelle mit anhängenden Leitungen transportiert und zur Herstellung des die Verbindungsstelle abdeckenden Schutzkörpers in ein Spritzgießwerkzeug eingelegt wird. Wenn dabei nicht sehr sorgfältig vorgegangen wird, ist ein Knicken der Flachleiter an der Austrittsstelle aus ihrer Isolierung kaum zu vermeiden. Die Flachleiter werden an einer solchen Knickstelle weiter geschwächt. Sie können dadurch bei einer Zugbelastung leicht reißen bzw. durchbrechen. Derartige Zugbelastungen können bereits beim Spritzen des Schutzkörpers durch das mit hohem Druck in das Spritzgießwerkzeug eingebrachte Material auftreten. Sie können aber auch während der Benutzung des Geräts, in das die Leitungen mit der Verbindungsstelle eingebaut werden, durch die weiterführende Leitung mit den stabileren Leitern erzeugt werden. Die Flachleiter können dadurch abgerissen oder so weit beschädigt werden, daß sich ein permanenter Wackelkontakt ergibt. In beiden Fällen wird die gesamte Anordnung unbrauchbar.Methods for connecting electrical lines in various embodiments have been known for years. Problems hardly arise if the conductors of the cables to be connected are stable conductors. If the conductors to be connected in one line are flat conductors with the usual small thickness in accordance with DE-OS 39 12 139 mentioned at the outset, considerable difficulties arise, however, since such flat conductors are mechanically very sensitive and can easily break. This is particularly noticeable after the electrically conductive connection of the flat conductors to stable conductors of the further line, if the connection point produced in this way is transported with attached lines and inserted into an injection molding tool to produce the protective body covering the connection point. If this is not done very carefully, the flat conductor will bend at the point of exit from its insulation hard to avoid. The flat conductors are further weakened at such a kink. You can easily tear or break through a tensile load. Such tensile loads can occur during the injection molding of the protective body due to the material introduced into the injection mold at high pressure. However, they can also be generated by the continuing line with the more stable conductors while the device in which the lines with the connection point are installed is being used. The flat conductors can be torn off or damaged to such an extent that there is permanent loose contact. In both cases the entire arrangement becomes unusable.

Mit dem bekannten Verfahren nach der eingangs geschilderten DE-OS 39 12 139 wird zum Schutz der Flachleiter vor dem Verbinden mit den hier als Rundleiter ausgebildeten stabilen Leitern ein Ring aus Isoliermaterial auf die Rundleiter aufgeschoben, der während des Spritzvorgangs durch einen Stempel an die Rundleiter angedrückt wird. Die Rundleiter sind dadurch so festgelegt, daß sie durch das einströmende Spritzmaterial nicht bewegt werden können. Die Verbindungsstellen sind also während des Spritzens gegen Zugbelastungen geschützt. Der Aufwand zur Durchführung dieses Verfahrens ist relativ hoch. Der Ring muß als zusätzliches Bauteil auf die Leiter aufgeschoben werden und das Spritzwerkzeug muß zusätzlich mit mindestens einem Stempel ausgerüstet werden. Außerdem bleibt die Verbindungsstelle zwischen den Leitern der beiden Leitungen gegen Zugbelastungen empfindlich, die auf die weiterführende Leitung einwirken.With the known method according to DE-OS 39 12 139 described above, a ring of insulating material is pushed onto the round conductor to protect the flat conductor from being connected to the stable conductors designed here as round conductors, which ring is pressed onto the round conductor during the spraying process becomes. The circular conductors are fixed in such a way that they cannot be moved by the inflowing spray material. The connection points are therefore protected against tensile loads during spraying. The effort to carry out this method is relatively high. The ring must be pushed onto the ladder as an additional component and the injection mold must also be equipped with at least one stamp. In addition, the connection point between the conductors of the two lines remains sensitive to tensile loads which act on the continuing line.

Der Erfindung liegt die Aufgabe zugrunde, das eingangs geschilderte Verfahren so weiterzubilden, daß auf einfache Weise eine auf Dauer sichere elektrisch leitende Verbindung zwischen einer Leitung mit Flachleitern und einer Leitung mit stabilen Leitern hergestellt werden kann.The invention has for its object to develop the above-described method so that a long-term, safe, electrically conductive connection between a line with flat conductors and a line with stable conductors can be made in a simple manner.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß die Enden der beiden Leitungen mit den abisolierten Leitern zunächst in einen mit entsprechenden Vertiefungen versehenen Träger aus Isoliermaterial lagerichtig eingelegt werden,
  • daß die durchzuverbindenden Leiter der beiden Leitungen danach miteinander verlötet werden und
  • daß abschließend auf die Verbindungsstellen der Leiter und die Enden der beiden Leitungen eine sich fest mit dem Träger verbindende Abdeckung aus Isoliermaterial aufgespritzt wird.
According to the invention, this object is achieved by
  • that the ends of the two lines with the stripped conductors are first inserted in the correct position in a support made of insulating material provided with corresponding depressions,
  • that the conductors of the two lines to be connected are then soldered to one another and
  • that finally a cover made of insulating material is sprayed onto the connection points of the conductors and the ends of the two lines.

Mit diesem Verfahren ergibt sich auf einfache Weise eine auf Dauer wirksame Zugentlastung für die empfindlichen Flachleiter. Die Zugentlastung ist bereits während des Spritzens der Abdeckung gegeben, da die zu verbindenden Leiter einerseits durch das Einlegen in die Vertiefungen und andererseits durch die beim Verlöten entstehende Wärme relativ fest mit dem Träger verbunden sind. Sie ist in der fertigen Anordnung auf Dauer zusätzlich durch die Abdeckung sichergestellt, deren Isoliermaterial beim Spritzen in alle zwischen Leitern und Träger verbleibenden Hohlräume und Spalte eindringt und die insbesondere die durch das Löten entstandenen verdickten Verbindungsstellen fest und unverrückbar umschließt. Auf die weiterführende Leitung einwirkende Zugkräfte können daher nicht auf die Flachleiter übertragen werden.With this method, strain relief for the sensitive flat conductors is effective in the long term. The strain relief is already given during the spraying of the cover, since the conductors to be connected are relatively firmly connected to the carrier on the one hand by inserting them into the depressions and on the other hand by the heat generated during soldering. In the finished arrangement, it is additionally ensured in the long term by the cover, the insulating material of which penetrates into all the cavities and gaps remaining between the conductors and the support and which, in particular, firmly and immovably encloses the thickened connection points caused by soldering. Tractive forces acting on the outgoing line cannot therefore be transferred to the flat conductors.

Es zeigen:

  • Fig. 2 eine Draufsicht auf eine nicht abgedeckte Verbindungsstelle.

  • Fig. 1 shows the ends of two electrical lines to be connected.
  • Fig. 2 is a plan view of an uncovered connection point.
  • Fig. 3 shows a cross section through a connection point produced with the method according to the invention.

In Fig. 1 ist auf der linken Seite ein Flachleiter-Bandleitung 1 - im folgenden kurz "FL-BL" genannt - dargestellt, die im gezeigten Ausführungsbeispiel mit zwei Flachleitern 2 ausgerüstet ist. Auf der rechten Seite der Fig. 1 ist eine weiterführende Leitung 3 gezeigt, die zwei beispielsweise als Rundleiter angebildete Leiter 4 aufweist. Die Flachleiter 2 der FL-BL 1 und die Leiter 4 der weiterführenden Leitung 3 sollen elektrisch leitend miteinander verbunden werden.In Fig. 1, a flat conductor ribbon cable 1 - hereinafter called "FL-BL" - is shown on the left side, which is equipped with two flat conductors 2 in the embodiment shown. On the right-hand side of FIG. 1, a further line 3 is shown, which has two conductors 4, for example designed as round conductors. The flat conductors 2 of the FL-BL 1 and the conductors 4 of the continuing line 3 are to be connected to one another in an electrically conductive manner.

Dazu werden zunächst die Leiter 2 und 4 der beiden Leitungen 1 und 3 abisoliert und auf Länge geschnitten. Die beiden Leitungen 1 und 3 werden dann mit ihren Enden in einen Träger 5 aus Isoliermaterial eingelegt, der dazu mit entsprechenden Vertiefungen ausgerüstet ist, in die sowohl die Leitungen 1 und 3 mit ihren Enden als auch die Leiter 2 und 4 eingelegt und in denselben lagerichtig fixiert werden können. Sie nehmen dann die aus Fig. 2 ersichtliche Position ein. Die Leiter 4 überdecken dabei die Flachleiter 2. An diesen Stellen werden die Leiter 2 und 4 miteinander verlötet, wobei sich Verbindungsstellen 6 und 7 ergeben.For this purpose, conductors 2 and 4 of the two lines 1 and 3 are first stripped and cut to length. The ends of the two lines 1 and 3 are then inserted into a carrier 5 made of insulating material, which is equipped for this purpose with corresponding recesses, into which both the ends of lines 1 and 3 and the conductors 2 and 4 are inserted and in the correct position in the same can be fixed. You then take the position shown in Fig. 2. The conductors 4 cover the flat conductors 2. The conductors 2 and 4 are soldered to one another at these points, resulting in connection points 6 and 7.

Nach Fertigstellung der Verbindungsstellen 6 und 7 sind die beiden Leitungen 1 und 3 bzw. ihre Leiter 2 und 4 elektrisch leitend miteinander verbunden. Sie liegen immer noch lagerichtig im Träger 5 und sind mit demselben einerseits durch dessen Vertiefungen, andererseits aber auch durch die beim Löten aufgebracht Wärme relativ fest verbunden. Durch diese Wärme wird das Material des Trägers 5 geringfügig angeschmolzen, so daS eine Art Verklebung zwischen den Leitern 2 und 4 an den Verbindungsstellen 6 und 7 mit dem Träger 5 erfolgt.After the connection points 6 and 7 have been completed, the two lines 1 and 3 or their conductors 2 and 4 are connected to one another in an electrically conductive manner. They are still in the correct position in the carrier 5 and are relatively firmly connected to the carrier 5 on the one hand by its depressions and on the other hand by the heat applied during soldering. By this heat, the material of the carrier 5 is melted slightly, so that there is a kind of bonding between the conductors 2 and 4 at the connection points 6 and 7 with the carrier 5.

Nach Fertigstellung der Verbindungsstellen 6 und 7 wird der Träger 5 mit den anhängenden Leitungen 1 und 3 in ein Spritzwerkzeug eingelegt, in welchem eine Abdeckung 8 auf den Träger 5 aufgespritzt wird. Das Isoliermaterial der Abdeckung 8 dringt dabei in sämtliche Vertiefungen und Spalte des Trägers 5 ein und füllt diese komplett aus. Es wird so gewählt, daß es sich fest mit dem Träger 5 verbindet. Dazu kann der Träger 5 auch noch mit Vorsprüngen und Hinterschneidungen ausgerüstet sein, hinter die sich das Isoliermaterial der Abdeckung 8 legt.After completion of the connection points 6 and 7, the carrier 5 with the attached lines 1 and 3 is placed in an injection mold, in which a cover 8 is sprayed onto the carrier 5. The insulating material of the cover 8 penetrates into all the depressions and gaps of the carrier 5 and fills them out completely. It is chosen so that it connects firmly to the carrier 5. For this purpose, the carrier 5 can also be equipped with projections and undercuts, behind which the insulating material of the cover 8 lies.

Wie aus Fig. 3 ersichtlich, sind die Verbindungsstellen 6 und 7 durch das Lötmaterial so verdickt, daß sich an diesen Stellen jeweils eine Art Knoten ergibt. Eine Zugbelastung, die beispielsweise auf die Leitung 3 ausgeübt wird, kann höchstens bis zu den Knoten weitergeleitet werden. Sie wirkt sich nicht belastend auf die Flachleiter 2 der FBL 1 aus.As can be seen from FIG. 3, the connection points 6 and 7 are thickened by the soldering material in such a way that there is a kind of knot at each of these points. A tensile load that is exerted on line 3, for example, can at most be passed on to the nodes. It has no negative impact on the flat conductor 2 of the FBL 1.

Die Abdeckung 8 kann, so wie in Fig. 3 dargestellt, nur auf den Träger 5 aufgespritzt werden. Es ist jedoch auch möglich, den Träger 5 zumindest teilweise mit zu umspritzen oder ganz in die Abdeckung 8 einzubetten, sofern die Abmessungen des Gerätes, in das die Verbindungsstelle eingebaut werden soll, das erlaubt. Auf jeden Fall muß sichergestellt sein, daß die Abdeckung 8 fest mit dem Träger 5 verbunden ist.As shown in FIG. 3, the cover 8 can only be sprayed onto the carrier 5. However, it is also possible to at least partially encapsulate the carrier 5 or to embed it completely in the cover 8, provided that the dimensions of the device into which the connection point is to be installed allow this. In any case, it must be ensured that the cover 8 is firmly connected to the carrier 5.
