Description
Die- Erfindung betrifft ein Lötgerät, bei dem die einen schleifenförmigen Stromweg bildende Lötspitze unmittelbar durch hindurchgeleiteten elektrischen Strom erhitzt wird. Derartige Lötgeräte sind in der Weise ausgebildet worden, daß der Vorderteil der Lötspitze nach Art eines verhältnismäßig kräftigen Bügels aus Chromniekelstahl gefertigt war. Das Gerät ist teuer und zu plump, um damit feinere Lötungen namentlich an schwer zugänglichen Stellen ausführen zu können.The invention relates to a soldering device in which the one loop-shaped Soldering tip that forms the current path directly through an electrical current passed through it is heated. Such soldering devices have been designed in such a way that the Front part of the soldering tip in the manner of a relatively strong bracket made of stainless steel was made. The device is expensive and too clumsy to allow for finer soldering in particular to be able to perform in hard-to-reach places.
Gemäß der Erfindung ist ein sehr zweckmäßiges und billigeres Lötgerät dadurch geschaffen, daß die beiden kräftigen Stromzuleitungen durch einen dünnen streifenförmigen Widerstandskörper, vorzugsweise aus Eisenblech, verbunden sind, der beim Stromdurchgang derart erwärmt wird, daß er eine Schicht flüssigen Lotes aufnimmt, mit dem die zu lötenden Teile in Berührung gebracht werden.According to the invention is a very convenient and cheaper soldering device created by the fact that the two powerful power lines through a thin strip-shaped resistance bodies, preferably made of sheet iron, are connected, which is heated in such a way during the passage of current that it creates a layer of liquid solder picks up, with which the parts to be soldered are brought into contact.
In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung in Fig. z in Seitenansicht, in Fig. 2 in Oberansicht mit verkürztem Griffteil in vergrößertem Maßstabe dargestellt. In den Griff g sind zwei stabförmige Stromzuführungen t1, t2 großen Querschnittes aus Eisen angeordnet, die am hinteren Ende an einen Transformator tv angeschlossen sind. Der untere Stab t2 erstreckt sich weiter nach vorn als der obere. Zwischen den beiden Stabenden ist ein etwas gebogenes Eisenblech e solchen Querschnittes befestigt, daß es bei Stromdurchgang auf die erforderliche Löthitze erwärmt wird. Das Lötzinn legt sich beim Schmelzen als eine Schicht z auf das Eisenblech e und die Stirnkante s des oberen Stromzuführungsstabes t1. Das Lötgerät wird beim Löten so gegen die zu verlötenden Teile w bewegt, daß diese von dem Lot z benetzt und damit verlötet werden.In the drawing, an embodiment of the subject matter of the invention is shown in Fig. Z in side view, in Fig. 2 in top view with a shortened handle part on an enlarged scale. In the handle g two rod-shaped power supply lines t1, t2 of large cross-section made of iron are arranged, which are connected at the rear end to a transformer tv. The lower rod t2 extends further forward than the upper one. Between the two ends of the rod, a somewhat curved sheet of iron is attached with a cross-section such that it is heated to the required soldering heat when the current passes through it. When it melts, the tin solder is deposited as a layer z on the iron sheet e and the front edge s of the upper power supply rod t1. During soldering, the soldering device is moved against the parts w to be soldered in such a way that they are wetted by the solder z and thus soldered.
Der Widerstandskörper kann außer aus Eisenblech auch aus Stahlblech oder einem sonstigen Stoff verhältnismäßig höheren Widerstandes, beispielsweise Molybdän, bestehen.In addition to sheet iron, the resistance body can also be made from sheet steel or some other material of relatively higher resistance, for example Molybdenum.
