Description
Beschreibung Verfahren zum Fixieren von über Kabelbäumen gezogener Isolierachläuche durch Injektion mit Thermoplast. Description Process for fixing cables pulled over cable harnesses Insulating tubes through injection with thermoplastic.
Die Erfindung betrifft ein Verfahren mit dem über Kabelbäumen gezogene Isolierschläuche durch Injektion mit Thermoplast in die verlangte Stellung zueinander fixiert werden, insbesondere in der Autoelektrik.The invention relates to a method with which the cable harnesses are pulled Insulating hoses by injection with thermoplastic in the required position relative to one another be fixed, especially in car electrics.
Ein derartiges Verfahren ist von großem praktischen Nutzen, es ist kostensparend und stellt eine feste homogene Verbindung zwischen Kabelbaum und Isolierschlauch her.Such a method is of great practical use, it is Saves costs and creates a solid, homogeneous connection between the cable harness and the insulating tube here.
Soweit mir bekannt, ist das bisherige Verfahren Isolierschläuche auf Kabelbäumen zu fixieren folgendes: Um den Kabelbaum - der aus einer unterschiedlichen Anzahl Kabel bestehen kann - wickelt man eine bestimmte Menge Isolierband oder Ähnliches um den Hohlraum zum Innendurchmesser des Isolierschlauches, der durch die unterschiedliche Zahl der Kabel verschieden groß ist, auszugleichen.As far as I know, the previous method is insulating tubing Cable harnesses to fix the following: To the cable harness - the one from a different Number of cables - you wrap a certain amount of electrical tape or something similar around the cavity to the inner diameter of the insulating tube, which is caused by the different Number of cables is different in size to compensate.
Nach diesem Arbeitsgang wird der Isolierschlauch über den mit Band umwickelten Kabelbaum geschoben und mit einem Klebstoff, der durch das offene Isolierschlauchende eingegeben wird, in die vorgeschriebene Lingenstellung fixiert.After this step, the insulating tube is taped over the wrapped wire harness pushed and with an adhesive that passes through the open end of the insulating tube is entered, fixed in the prescribed length position.
Diese Art der Fixierung ist umständlich, zeitraubend und in der Qulität nicht optimal.This type of fixation is cumbersome, time consuming and of high quality not optimal.
Der Erfindung liegt die Aufgabe zugrunde, zwischen Kabelbaum und Isolierschlauch eine schnelle und gute Verbindung herzustellen.The invention is based on the object between the cable harness and the insulating tube to establish a fast and good connection.
Nach der Erfindung wird der Isolierschlauch mit eingezogenem Kabelbaum in eine offene Form eingelegt, die den Isolierschlauch - nach dem Schließen der Form - in seinem Durchmesser voll umfaßt, wobei die Länge der Umfassung ca. 15 x Durchmesser sei sollte. Die beiden Enden des Schlauches können frei aus der Form heraushängen.According to the invention, the insulating tube with a retracted cable harness placed in an open mold, the insulating tube - after closing the Shape - fully encompassed in its diameter, the length of the enclosure being approx. 15 x Diameter should be. The two ends of the hose can be free from the mold hang out.
Die Form wird zweckmäßig auf eine kleine vertikale Spritzgießmaschine aufgebaut, deren Düse in Form ähnlich einer Injektionsnadel ausgebildet iat.The mold is conveniently placed on a small vertical injection molding machine constructed, whose nozzle is designed in the form of an injection needle.
Beim Vorfahren des Spritzzylinßers taucht die Düsenspitze in den zylindrischen Hohlraum der Form ein in dem der Isolierschlauch mit dem eingezogenen Kabelbaum liegt, durchsticht die Wandung des Isolierschlauches und füllt den Hohlraum zwischen den Kabeln und dem Isolierschlauch durch den Druck des Spritzkolbens mit Thermoplast z. B. Weich PVC.When the injection cylinder moves forward, the nozzle tip plunges into the cylindrical one Form a cavity in which the insulating tube with the retracted wiring harness lies, pierces the wall of the insulating tube and fills the cavity between the cables and the insulating hose by the pressure of the injection plunger with thermoplastic z. B. Soft PVC.
In der Form wird gegenüber der Eintauchstelle der Düse ein federnder Stift angebracht, der den Kabelbaum gegen die Düsenspitze drückt.In the form, opposite the immersion point of the nozzle, there is a resilient one Pin attached that presses the wiring harness against the nozzle tip.
Beim Einspritzen von Thermoplast federt der Stift bedingt durch den Spritzdruck in seine Endstellung die dem äußeren Durchmesser des Isolierschlauches entspricht zurück.When thermoplastic is injected, the pin springs due to the Injection pressure in its end position that corresponds to the outer diameter of the insulating tube corresponds to back.
Der Thermoplast geht mit der Kabelisolierung und mit dem Isolierschlauch eine innige Verbindung ein und gewährleistet so eine feste, saubere Fixierung der Kabel mit dem Isolierschlauch.The thermoplastic goes with the cable insulation and with the insulating tube an intimate connection and thus ensures a firm, clean fixation of the Cable with the insulating tube.
Die Kabelbäume sind bei Verwendung von Thermoplasten mit hohem Weichmachergehalt sehr flexibel.The cable harnesses are made using thermoplastics with a high plasticizer content very flexible.
Die so fixierten Isolierschläuche sind äuBerlich durch den ca. 2 mm großen Einspritzpunkt am Sclauchaußendurchmesser zu erkennen.The insulating hoses fixed in this way are externally through the approx. 2 mm The large injection point can be seen on the outside diameter of the hose.
