Description

daß solche bereits eingeknickten Stifte mit der entsprechenden Vorzugsrichtung in die Form eingelegt werden müssen.that such already buckled pins are inserted into the mold with the corresponding preferred direction Need to become.

In weiterer Ausgestaltung der Erfindung können bei mehreren Anschlußelementen alle Führungshohlzylinder die gleiche Vorzugsausknickrichtung durch entsprechende Anordnung der Ausnehmungen erzwingen. Es ist auch vorteilhaft, daß die Werkzeughälften zugleich Gieß- oder Spritzformen zum Herstellen des Isolierstoffträgers bilden. joIn a further embodiment of the invention can If there are several connection elements, all guide hollow cylinders have the same preferred buckling direction Force a corresponding arrangement of the recesses. It is also advantageous that the tool halves at the same time form casting or injection molds for producing the insulating material carrier. jo

Die untere Werkzeughälfte 1 gemäP Fig. 1 weist zwei Führungshohlzylinder 2 auf. Ihre Eingangsöffnungen 3 sind zum besseren Einführen der Anschlußdrähte 4 als Trichter ausgebildet. An den Seiten weist die untere V/erkzeughälfte 1 eine Umrandung 5 auf, «5 die ein Ausfließen des später in die dadurch gebildete Hohlform 6 durch die Einspritzöffnungen 7 einzubringenden Isolierstoffs verhindert. Die darüber angeordnete obere Werkzeughälfte 8 weist ebenfalls zwei Führungshohlzylinder 9 auf, deren rechte ivlan- -|o telhalbfläche 10 jeweils bis zur Begrenzungsfläche 11 der Hohlform 6 für den Isolierstoffträger 12 reicht. Dagegen ist die gegenüberliegende linke Mantelhalbfläche 13 durch die Ausnehmung 14 verkürzt. Damit ist die Knicklänge des Anschlußdrahtes 4 links länger ;i5 als rechts und dieser wird beim Aufeinanderpressen der beiden Werkzeughälften 1 und 8 zwangsläufig nach links aasknicken.The lower tool half 1 according to FIG two guide hollow cylinders 2. Your inlet openings 3 are for better insertion of the connecting wires 4 designed as a funnel. The lower tool half 1 has a border 5 on the sides, «5 which is later to be introduced into the hollow shape 6 thus formed through the injection openings 7 Prevents insulating material. The upper tool half 8 arranged above it also has two guide hollow cylinder 9, the right ivlan - | o half surface 10 extends up to the boundary surface 11 of the hollow form 6 for the insulating material carrier 12. In contrast, the opposite, left half-surface area 13 is shortened by the recess 14. In order to the buckling length of the connecting wire 4 is longer on the left; i5 than on the right and this becomes longer when pressed together of the two tool halves 1 and 8 necessarily bend to the left.

Vor dem Zusammenpressen der beiden Werkzeughälften 1 und 8 sind zunächst die beiden Führungshohlzylinder 2 in der unteren Werkzeughälfte 1 mit den Anschlußdiähten4 zu bestücken und dann die obere Werkzeughälfte 8 in Richtung des Pfeils 15 nach unten zu pressen. Nach dem Zusammenpressen der beiden Werkzeughälften 1 und 8 ist durch die Einspritzöffnungen 7 Isolierstoff zur Erstellung des Isolierstoffträgers 12 in die Hohlform 6 einzuspritzen. Dies ist in F i g. 2 dargestellt.Before the two tool halves 1 and 8 are pressed together, the two guide hollow cylinders are first 2 in the lower tool half 1 with the connecting wires 4 and then the to press upper tool half 8 in the direction of arrow 15 downwards. After pressing together the two tool halves 1 and 8 is through the injection openings 7 insulating material to create the Inject insulating material carrier 12 into hollow mold 6. This is in FIG. 2 shown.

Selbstverständlich können die Anschlußdrähte 4 auch von nicht dargestellten Vorratsdrahtrollen zugeführt werden. Dazu müssen die Führungshohlzylinder 9 in der oberen Werkzeughälfte 8 bis zu ihrem oberen Rand durchgehen, wie es durch Strichelung angedeutet ist. Durch sie können die Drähte für die einzelnen Anschlußdrähte 4 zugeführt werden, bis sie auf den Boden der Führungshohlzylinder 2 in der unteren Werkzeughälfte 1 aufstoßen. Dann werden die Drähte über der oberen Werkzeughälfte 8 beschnitten, festgeklemmt und ebenso wie vorher beschrieben gestaucht und der Isolierstoff eingespritzt.Of course, the connecting wires 4 can also be supplied from supply wire rolls (not shown) will. For this purpose, the guide hollow cylinder 9 in the upper tool half 8 up to their go through the upper edge as indicated by the dashed lines. Through it the wires for the individual connecting wires 4 are fed until they hit the bottom of the guide hollow cylinder 2 in the lower Open tool half 1. Then the wires are cut over the upper tool half 8, clamped and compressed as previously described and injected the insulating material.

Fig. 3 zeigt zwei Anschluüdrähte4 in einem Isolierstoffträger 12. Dabei ist gleichzeitig durch Strichelung angedeutet, wie sich bei einer unzulässigen Ausknickung die zwei Anschlußdrähte 4 so stark nähern könnten, daß die Durchschlagfestigkeit des dazwischenliegenden Isolierstoffs nicht mehr ausreicht und sogar die Gefahr besteht, daß sich die beiden Anschlußstifte 4 berühren.Fig. 3 shows two connecting wires 4 in an insulating material carrier 12. At the same time, it is indicated by dashed lines, as is the case with an impermissible Buckling could approach the two connecting wires 4 so closely that the dielectric strength of the intermediate Insulating material is no longer sufficient and there is even a risk that the two Touch connector pins 4.

Die Vorrichtung kann natürlich auch zum Knicken von bereits im Isolierstoffträger 12 eingebetteten Anschlußelementen 4 dienen. Dann muß nur durch entsprechende Mittel, z. B. durch Zuführen von Wärme oder Ultraschall, dafür gesorgt werden, daß der Isolierstoffträger 12 diese Verformung zuläßt, ohne Spannungsrisse zu erhalten.The device can of course also be used to buckle connection elements already embedded in the insulating material support 12 4 serve. Then only has to be done by appropriate means, e.g. B. by adding heat or ultrasound, to ensure that the insulating material 12 allows this deformation without To maintain stress cracks.

Schließlich kann als Anschlußelement 4 außer rundem auch vierkantiger, rechteckiger oder ovaler Draht verwendet werden. Dann sind natürlich dem Führungshohlzylinder 2,9 die die Vorzugsausknickrichtung bestimmenden Ausnehmungen 14 und die Einlauftrichter 3 dieser Querschnittsform anzupasFinally, the connection element 4 can also be square, rectangular or oval in addition to round ones Wire can be used. Then of course the guide hollow cylinder 2.9 are the preferred buckling direction defining recesses 14 and the inlet funnel 3 to adapt this cross-sectional shape
