Abstract

Multiple electric connectors of the type with upper and lower comb-like members which are fastened together and to which the connecting wires are attached, and which are then brought into connection with a corresponding contact plate, are made in apparatus where the required number of conductors (4, 5, 6) in strip of wire form is unwound from a set of spools (1, 2, 3) and fed to a frame where they are attached to the comb shaped members (7) by application of heat and pressure, then advanced with a stepping action, followed by cutting the conductors to length. An ultrasonic welding member (8) is raised and lowered at the welding position, then an advancing member (9) moves the assembly forwards and a further member (10) bends the wires downwards.

Description

Verfahren zur Herstellung von elektrischen Steckverbindungen Die Erfindung betrifft ein Verfahren zur Herstellung-von elektrischen Steckverbindungen, insbesondere Vielfachsteckerleisten.Method for producing electrical plug connections The invention relates to a method for producing electrical plug connections, in particular Multiple connector strips.

Im allgemeinen werden Vielfachsteckerleisten derart hergestcllt, daß die Kammern eines Isolierkörpers entweder von Hand oder bei größerer Stückzahl automatisch Kontaktfedern eingesetzt werden. Diese Kontakfedern werden in der Regel durch komplizierte Präge- und Stanzvorgänge hergestellt, da zumindest bei gutfunktionierenden Steckern vorzugsweise~2 unabhängig voneinander federnde Kontaktstellen pro Anschluß gefordert werden sollte und irgendawelche, meist federnde, Halterungen vorgesehen werden müssen, die die Kontalrtfedern in den Kammern des Isolierkörpers fixieren und halten.In general, multiple connector strips are manufactured in such a way that the chambers of an insulating body either by hand or automatically in the case of larger quantities Contact springs are used. These contact springs are usually complicated by Embossing and stamping processes produced, as at least with well-functioning connectors preferably ~ 2 independently resilient contact points per connection required should be and which, mostly resilient, brackets must be provided, which fix and hold the Kontalrtfedern in the chambers of the insulating body.

Aufgabe der Erfindung ist es, diese Nachteile, nämlich die Einzelfertigung einer komplizierten Kontaktfeder pro Kontaktstelle sowie das einzelne Bestücken eines Vielfachsteckers mit der erforderlichen Anzahl von KontalrtSedern zu vermeiden.The object of the invention is to overcome these disadvantages, namely individual production a complicated contact spring per contact point as well as the individual assembly a multiple plug with the required number of KontalrtSedern to avoid.

Die Erfindung ist dadurch gekennzeichnet, daß das Kontaktmaterial in Borm von Streifen, Bändern oder Drähten von einer der Polzahl eines Steckers entsprechenden Anzahl von Vorratsrollen einem Steckerteil zugeführt, mit diesem durch Anwendung von Druck und/oder Wärme verbunden, das Kontaktmaterial durch Biegevorgänge in geeignete Kontaktform gebracht und abgeschnitten wird und daß nach erfolgter Verbindung der Vorschub des Kontaktmaterials erfolgt.The invention is characterized in that the contact material in the form of strips, ribbons or wires from one of the number of poles of a connector corresponding number of supply rolls fed to a plug part with this connected by the application of pressure and / or heat, the contact material by bending processes is brought into suitable contact form and cut off and that after Connection of the feed of the contact material takes place.

Die Erfindung wird anhand der Ausführungsbeispielen darstellender Figuren nSher-erläutert Figur 1 stellt einen kompletten Stecker dar, der durch Zusammenfügen von 2 gleichen Steckerhälften entsteht und bei dem der besseren Übersicht wegen jeweils nur 3 Kontaktkammern bestückt sind.The invention is illustrated by means of the exemplary embodiments Figures nSher-explained Figure 1 shows a complete connector represents, which is created by joining 2 identical connector halves and in which For the sake of clarity, only 3 contact chambers are fitted in each case.

Figur 2 und 3 stellen jeweils die beiden Steckerteile dar, wie sie aus der in Figur 4 beschriebenen Vorrichtung entstehen.Figures 2 and 3 each represent the two connector parts as they arise from the device described in FIG.

Figur 4 zeigt ein Ausführungsbeispiel einer Vorrichtung, bei dem der Arbeitsablauf zur Herstellung eines Steckerteiles nach Figur 2 und 3 gezeigt wird.Figure 4 shows an embodiment of a device in which the The workflow for producing a plug part according to FIGS. 2 and 3 is shown.

Figur 5 zeigt die gleichen Arbeitsabläufe wie Figur 4 in schematischer Reihenfolge, jedoch jeden Arbeitsgang nacheinander schrittweise dargestellt.FIG. 5 shows the same workflows as FIG. 4 in schematic form Sequence, but each work step shown one after the other.

Gleiche Deile sind in den Figuren mit gleichen Bezugszeichen versehen.The same parts are provided with the same reference symbols in the figures.

Der in den Figuren 1, 2 und 3 dargestellte Stecker besteht aus den Isolierstoffteilen 7 und 7' welche vorzugsweise gleich sind.The connector shown in Figures 1, 2 and 3 consists of the Insulating parts 7 and 7 'which are preferably the same.

Die Kontaktfedern 18 bestehen jeweils aus mehreren vergoldeten Bronzedrähten, die an den Stellen 19 mit dem Isolierstoffteil 7 bzw. 7' verschweißt und derart gebogen sind, daß sie die von den Aussparungen 20 gebildete Ebene schräg schneiden. In die Aussparungen 20 wird das nur angedeutete Gegenstück 21 des Steckers eingeführt, das im wesentlichen aus einer Isolierstoffplatte mit Kontakten 22 besteht.The contact springs 18 each consist of several gold-plated bronze wires, which are welded at the points 19 to the insulating part 7 or 7 'and such are bent that they cut the plane formed by the recesses 20 obliquely. The only indicated counterpart 21 of the plug is inserted into the recesses 20, which essentially consists of a sheet of insulating material with contacts 22.

Wie in Figur 4 dargestellt, befindet sich das Kontaktmaterial, das aus Flach-, Rechteck- oder Rundmaterial bestehen kann, auf den Vorratsrollen 1, 2 und 3, von denen der Übersicht halbe, abweichend von der Nutenzahl bzw-.-An-3-ahl---der-Kontaktstell-endes Steckers, nur bei dargestellt sind. Im vorliegenden Beispiel besteht das Kontaktmaterial aus vergoldeten Bronzedrähten und zwar werden von jeder Vorratsrolle mindestens 2 Drähte gleichzeitig abgespult, so daß an jeder Kontaktstelle immermehrere, unabhängig voneinander federnde, Konta'et-Ubergänge gewährleistet sind. Die Drähte werden über Fü7Irungs7canaIe 4, 5 und 6 (Figur 4) bei Beginn der Fertigung in die Ausgangsstellung 5/1 der Figur 5 gebracht. Ein in der Position 0 (Fig. 4) befindlicher Steckerkörper 7 aus Isolierstoff wird durch Niedergang der Sonotrode 8 einer Ultraschall-Schweißvorrichtung erwärmt, wobei die zugeführten Drähte mit dem Steckerkörper verschweißt werden (Figur 5/2). Anschließend werden die Kontaktfedern durch Bewegen des Stempels 9 in Pfeilrichtung umgebogen und mit einer Schneidkante 10 abgeschnitten (Fig. 5/3) Während dieser Arbeitsabläufe wird ein neuer Steckerkörper 7 von Position A ngBcih Position B gebracht. Wenn jetzt die Vorschubstangen 11 und 92/in Pfeilrichtung bewegt werden, so gelangt der neue Steckerkörper von Position B nach Position C, wobei gleichzeitig über die Distanzstücke 13 und 14 der vorher in Position G befindliche, fertige Stecker die in Figur 5/4 gezeigte Stellung -einnimmt. Auf Grund der Tatsache, daß die Kontakt-Drähte mit dem ersten Stecker bereits verschweißt waren, werden auch die Drähte automatisch von den Vorratsspulen um den für einen Stecker erforderlichen Betrag nachgezogen. Nach erfolgtem Vorschub werden die Distanzstücke 13 und 14 nach außen geschwenkt, auf der Achse 15 in die Anfangsstellung zurückgeführt und wieder eingeschweSrt (Figur 4). Von nun an wiederholen sich die einzelnen Arbeitsoperationen turnusmäßig.As shown in Figure 4, there is the contact material that can consist of flat, rectangular or round material, on the supply rolls 1, 2 and 3, of which, for the sake of clarity, deviating from the number of slots or -.- An-3-ahl --- the-contact point Connector, are only shown at. In the present example, the contact material consists of gold-plated bronze wires and at least 2 wires are required from each supply roll unwound at the same time, so that at each contact point there are always several, independently of one another resilient, Konta'et transitions are guaranteed. The wires are connected via guide rails 4, 5 and 6 (Figure 4) at the start of production in the starting position 5/1 of the figure 5 brought. A plug body 7 made of insulating material in position 0 (FIG. 4) is heated by the sinking of the sonotrode 8 of an ultrasonic welding device, whereby the supplied wires are welded to the connector body (Figure 5/2). Then the contact springs are set by moving the punch 9 in the direction of the arrow bent over and cut off with a cutting edge 10 (Fig. 5/3) During this A new plug body 7 is brought from position A to position B in the workflow. If the feed rods 11 and 92 / are now moved in the direction of the arrow, this is achieved the new connector body from position B to position C, while at the same time using the Spacers 13 and 14 of the previously located in position G, the finished connector -takes position shown in Figure 5/4. Due to the fact that the contact wires With the first connector already welded, the wires are also automatically pulled by the supply reels by the amount required for a connector. After the feed has taken place, the spacers 13 and 14 are swiveled outwards, returned to the starting position on the axis 15 and welded in again (Fig 4). From now on, the individual work operations are repeated on a regular basis.
