Description

Handgerät zum Verschweißen von Kunststoffolien, insbesondere zum Herstellen von Kabelbaum -Abbindungen Beim Verdrahten von elektrischen Geräten ist es üblich, die einzelnen Schaltdrähte zu sogenannten Kabelbäumen zusammenzufassen. Dies erfolgt entweder mit zu umwickelndem Zwirn oder auch durch Umlegen von Kunststoffstreifen, die bisher durch Kontaktwärme von Erwärmungsgeräten, z. B. von elektrischen Lötkolhen, zu einem Ring verschweißt wurden. Beide Abl)indarten sind insofern nachteilig, als ihre Handhabung viel Zeit in Anspruch nimmt und insbesondere bei der letztgenannten Art zudem Zeine Gewähr für ein einwandfreies Verschweißen der Kunststoffolie gegeben ist. So kann es z. B. vorkommen, daß bei zu gering bemessener Wärmeeinwirkung eine schlechte Schweißstelle entsteht, dagegen hei übermäßiger Wärmeeinwirkung Verbrennungen auftreten, welche zu Beschädigungen der Leiterisolation führen können. Es sind zwar zu anderen Zwecken mit Hochfrequenz gespeiste Handgeräte mit regelbaren Anpaßgliedern und Überwachungsmitteln bekaimtgeworden, bei denen die zu behandelnden Gegenstände im kapazitiven Hochfrequenzfeld erwärmt werden und die Zuführung der Wärme nach Erreichen einer eingestellten Zeitspanne selbsttätig abgeschaltet wird. Diese Geräte sind jedoch zum Herstellen von I(abell)aum-Al)bindungell ungeeignet, weil mit ihnen jeweils nur eine einzige Abbindstelle gefertigt werden kann, wobei die Nebenarbeiten, wie Zuschneiden der Kunststoffstreifen u. dgl., einen beträchtlichen Zeitaufwand erfordern.Hand tool for welding plastic films, in particular for manufacturing of wiring harness ties When wiring electrical equipment, it is common to combine the individual jumper wires into so-called cable harnesses. this happens either with twine to be wrapped or by folding plastic strips, which were previously caused by contact heat from heating devices, e.g. B. of electric soldering irons, were welded to a ring. Both types are disadvantageous insofar as their handling takes a long time, and especially with the latter Art also gives a guarantee for perfect welding of the plastic film is. So it can be B. happen that if the heat exposure is too low, a bad weld occurs, on the other hand burns from excessive heat exposure occur which can damage the conductor insulation. It is true hand-held devices with adjustable adapter elements fed with high frequency for other purposes and monitoring means, in which the objects to be treated are heated in the capacitive high-frequency field and the supply of heat after Is switched off automatically when a set period of time is reached. These devices are, however, unsuitable for the production of I (abell) aum-Al) because of them only one binding point can be made at a time, whereby the ancillary work, such as cutting the plastic strips and the like, a considerable expenditure of time require.

Es sind ferner zangenartige Werkzeuge mit Hochfrequenzerwärmungseinrichtungen bekannt, mit denen elektrisch nicht leitende Werkstoffe beispielsweise verformt oder mit Einprägungen versehen werden können. Auch diese bekannten Einrichtungen sind aus den obenerwähnten Gründen nachteilig und für die Herstellung von Kabelbaum-Abbindungen ungeeignet. There are also pliers-like tools with high-frequency heating devices known, with which electrically non-conductive materials deformed, for example or can be embossed. Also these well-known facilities are disadvantageous for the reasons mentioned above and for the production of cable harness ties not suitable.

Die Nachteile der bekannten Einrichtungen sollen durch das Handgerät nach der Erfindung auf einfache Weise dadurch beseitigt werden, daß mehrere nebeneinanderliegende Erwärmungsstellen und eine entsprechend Anzahl von die Kunststoffolien enthaltenden Vorratsbehältern unmittelbar am Handgerät derart angeordnet sind, daß bei Betätigung des Gerätes zunächst die Kunststoffolien auf passende Länge abgeschnitten und in ihre Schweißlage gebracht und dann die Hochfrequenzenergie über vorzugsweise auswechselbare Backen, die auf der Innenseite mit an flochfrequenz liegenden und erforderlichenfalls mit Anpaßgliedern verbundenen metallischen Belegungen versehen sind, zugeführt wird. The disadvantages of the known devices are said to be due to the hand-held device can be eliminated according to the invention in a simple manner that several adjacent Heating points and a corresponding number of the plastic films containing Storage containers are arranged directly on the handheld device in such a way that when actuated of the device, first cut the plastic film to the appropriate length and put it in brought their welding position and then the high frequency energy via preferably replaceable Jaws, which are on the inside with at floch frequency and if necessary are provided with metal coverings connected to adapter members, is supplied.

An Hand der Zeichnung werden ein Ausführungsbeispiel und weitere Einzelheiten der Erfindung näher erläutert. An exemplary embodiment and others are illustrated with the aid of the drawing Details of the invention explained in more detail.

Das in Fig. 1 in Ansicht dargestellte Handgerät l>esteht im wesentlichen aus den beiden, vorzugsweise aus Isolierstoff hergestellten Zangenteilen 1 und 2, die mit Hilfe eines Nietes 3 wie die Teile einer Kneif-' zarge miteinander verbunden sind. Das von den Teilen 4 und 5 gebildete Maul des Gerätes umfaßt das mit einem Kunststoffolienstreifen 6 umlegte Leiterbündel 7. Um das Gerät für Leiterbündel mit verschieden großem Durchmesser verwenden zu können, ist es vorteilhaft, das Maul des Gerätes mit auswechselbaren Backen zu versehen. Eine solche Backe ist in Fig. 2 in vergrößertem Maßstabe dargestellt und besteht vorzugsweise aus einem Isolierstoffkörper 8, der an der Innenseite mit einem metallischen Belag 9 versehen ist. Der metallische Belag ist mit einem Steckerstift 10 verbunden, der sowohl die elektideVerhindung mit einer der Hochfrequenzzuleitungen 11 und 12 herstellt als auch zur Halterung der Backen im Gerätemaul dient. Im Bedarfsfalle können zusätzlich noch weitere, an sich bekannte Befestigungsmittel verwendet werden. Da die beiden Backen mit den abzubindenden Leitungsdrähten einen Kondensator mit einem je nach Art der Leiter verschiedenen Dielektrikum darstellen, ist es mit Rücksicht auf einen guten Wirkungsgrad vorteilhaft, vorzugsweise abstimmbare Anpaßglieder in Form einer oder mehrerer Induktionsspulen 13 und/oder Kondensatoren 14 vorzusehen, die unmittelbar an oder in Teilen des zangenartigen Gerätes untergebracht sind, wie dies beispielsweise im Zangenteil 2 der Fig. 1 gestrichelt angedeutet ist. The hand-held device shown in view in FIG. 1 essentially consists from the two pliers parts 1 and 2, preferably made of insulating material, which are connected to each other with the help of a rivet 3 like the parts of a pinch frame are. The mouth of the device formed by the parts 4 and 5 includes the one Plastic film strips 6 folded wire bundles 7. Around the device for wire bundles To be able to use different diameters, it is advantageous to use the To provide the mouth of the device with exchangeable jaws. Such a cheek is in Fig. 2 is shown on an enlarged scale and preferably consists of an insulating body 8, which is provided with a metallic covering 9 on the inside. The metallic one Covering is connected to a plug pin 10, which is both the electrical connection with one of the high-frequency leads 11 and 12 as well as for holding the jaw is used in the device mouth. If necessary, additional, fastening means known per se are used. Since the two jaws with the lead wires to be tied off a capacitor with a depending on the type of conductor represent different dielectric, it is with regard to a good efficiency advantageous, preferably tunable adapter members in the form of one or more induction coils 13 and / or capacitors 14 to be provided directly on or in parts of the pincer-like Device are housed, as shown by dashed lines in the pliers part 2 of FIG. 1, for example is indicated.

Da die Länge der Kunststoffstreifen von dem Durchmesser des Leiterbündels 7 abhängig ist, wird das Gerät vorteilhaft mit Schneidbacken 15 versehen, die den im Vorratsbehälter 16 in Rollenform befindlichen Kunststoffstreifen auf passende Länge abschneiden. Daraufhin werden die beiden Enden des a)>geschn i ttenen Streifens überlappt angeordnet und mit dem Handgerät zusammengepreßt, wobei der Hochfrequenzstromkreis durch den Schalter 17 geschlossen wird. Die Einwirkdauer der Hochfrequenz wird vorteilhaft durch ein am Handgerät oder am Hochfrequenzgenerator befindliches Zeitschaltwerk bekannter Bauart begrenzt, wodurch bei Schweißvorgängen gleicher Art eine Verbrennung des Schweißgutes und der darunterliegenden Leiterisolation vermieden wird. Because the length of the plastic strips on the diameter of the conductor bundle 7 depends, the device is advantageously provided with cutting jaws 15, the the plastic strips located in the storage container 16 in roll form on matching Cut off the length. Then the two ends of the a)> cut strip arranged overlapped and pressed together with the hand-held device, the high-frequency circuit is closed by switch 17. The duration of exposure to the high frequency becomes advantageous by a timer on the handheld device or on the high-frequency generator known design, which results in combustion during welding processes of the same type of the weld metal and the conductor insulation underneath is avoided.

T)ie Erfindung beschränkt sich nicht auf das dargestellte Ausführungsbeispiel, sondern sie kann in mehrfacher Weise abgewandelt werden. So ist es z. B. möglich, die Hochfrequenzspannung erst bei entsprechender Backenstellung ein- oder auszuschalten oder den Einschaltvorgang erst von einem entsprechenden Schweißdruck abhängig zu machen. Ferner ist es möglich, die Anpaßglieder nicht - wie in Fig. 1 dargestellt - im Handgriff des Gerätes, sondern diese unmittelbar im oder am Maul des Gerätes anzubringen. The invention is not limited to the illustrated embodiment, but it can be modified in several ways. So it is z. B. possible switch the high-frequency voltage on or off only when the jaws are in the appropriate position or the switch-on process depends on a corresponding welding pressure do. It is also possible not to use the adapter - as shown in FIG - in the handle of the device, but this directly in or on the mouth of the device to attach.
