Draht mit zwei IsolationsschichtenWire with two layers of insulation
Es ist ein Draht mit einer inneren und einer äusseren Isolationsschicht als sogenannter Backlackdraht bekannt, bei welchem die innere Isolationsschicht aus einem härtbaren Kunstharzlack, welche Schicht durch ein Tauchverfahren erzeugt und anschliessend eingebrannt wird, und die äussere Isolationsschicht aus thermoplastischem Kunststoff besteht. Vielfach ist dieser Backlackdraht infolge seines beschränkten Isoliervermögens als Schaltdraht in elektrischen Einrichtungen nicht verwendbar. Ausserdem ist er verhältnismässig steif, so dass an seinen Biegestellen leicht Risse in den Isolierschichten entstehen können. Zudem ist es sehr umständlich, die auf den Draht eingebrannte innere Isolationsschicht zu ent-It is a wire with an inner and an outer insulation layer known as a so-called baked enamel wire, in which the inner insulation layer consists of a hardenable synthetic resin varnish, which Layer is created by a dipping process and then burned in, and the outer insulation layer is made of thermoplastic Made of plastic. In many cases, this baked enamel wire cannot be used as a jumper wire in electrical equipment due to its limited insulating capacity. It is also proportionate stiff, so that cracks can easily develop in the insulating layers at its bending points. In addition, it is very cumbersome to remove the inner insulation layer burnt onto the wire

fernen, tun darauf blanke Schaltstellen zu erhalten, so dass seine Verwendung als Schaltdraht zu Zeitverlusten führt. Welter 1st ein Draht f welcher zwei Isolationsschichten aus verachiodenen Kunststoffen aufweist, bekannt, bei dem der die innere Ieolationaschicht bildende Kunststoff zwar vernaltnismässig gute Isolationae.igenschaften jedoch eine geringe, medhanische Vlderstandsfähigkeit hat. Sie aussere Isolationsschicht bildet hauptsäch-Hch eine Schutzschicht gegen mechanische Einflüsse, wie Abrieb usw, und ist weniger gut isolierend. Dieser Draht dient zwar für Schaltzwecke, beim Fertigen von Kabelbäumen 1st es jedoch erforderlich, die den Kabelbaum bildenden Drähte, wie allgemein üblich, mittels Schnur oder Klebeband zusammenzuhalten. far away, do care to maintain bare switching points, so that its use as a jumper wire leads to time losses. A wire f which has two insulation layers made of verachiodinated plastics is known, in which the plastic forming the inner insulation layer has negligibly good insulation properties but a poor medical resistance. The outer insulating layer mainly forms a protective layer against mechanical influences, such as abrasion, etc., and is less insulating. Although this wire is used for switching purposes, when manufacturing cable harnesses it is necessary, as is common practice, to hold the wires forming the cable harness together by means of cord or adhesive tape.
Die Erfindung bezieht sich nun auf einen» Draht mit zwei Isolationsschichten, der es ermöglicht, Kabelbäume usw. zu fertigen, ohne dabei die Drähte, wie bisher üblich, zusammenbinden zu müssen· Gemäss der Erfindung wird dieses Ziel dadurch erreicht, dass beide Isolationaschichten des Drahtes aus einem thermoplastischen Kunststoff bestehen, wobei der thermoplastische Kunststoff der äusseren Isolationsschicht, die z.B. aus Polyäthylen besteht, gegenüber demjenigen der inneren Isolationsschicht, die z.B. aus Polyvinylchlorid besteht, eine niedrigere Schmelztemperatur aufweist.The invention now relates to a »wire with two layers of insulation, which makes it possible to manufacture cable harnesses etc. without having to tie the wires together, as was previously the case According to the invention, this aim is achieved in that both insulation layers of the wire are made of a thermoplastic Made of plastic, with the thermoplastic plastic of the outer insulation layer, e.g. made of polyethylene consists of a lower melting temperature than that of the inner insulation layer, which consists e.g. of polyvinyl chloride having.

As a result, the coatings 3 of the adjacent wires 1 soften in such a way that they fuse with each other · When they cool down, they solidify again and the individual wires 1 are firmly connected to one another by their covers 3 · In this way, even complicated cable harnesses can be produced in a relatively short time Advantage that they look very clean · The one described However, wire can also be used for other purposes, e.g. for
