Description
Anordnung zur Verbindung eines Heizwendelendes mit einer Anschlußschraube.Arrangement for connecting a heating coil end with a connecting screw.
Die Erfindung betrifft eine Anordnung zur Verbindung eines Heizwendelendes mit einer Anschlußschraube, insbesondere bei elektrischen Wassererhitzern. Bisher hat man die Heizwendelenden mit der Anschlußschraube verlötet. Das Löten des hier verwendeten Widerstandsmaterials bereitet bekanntlich Schwierigkeiten und führt oft zu elektrisch und mechanisch unsicheren Verbindungen. Daher ist man vielfach dazu übergegangen, das Heizwendelende zu einer Ose zu biegen und mittels Mutter und Gegenmutter an die Anschlußschraube anzuklemmen, Bei häufigem Temperaturwechsel können sich derartige Klemmverbindungen trotz einer Muttersicherung lösen und unsichere Kontakte geben. Es ist ferner bekannt, das Heizwendelende in einer Nut oder einem Schlitz der Anschlußschraube einzustemmen. Dazu ist ein Fräsarbeitsgang zum Schlitzen oder Nuten der Anschlußschraube erforderlich, der unerwünschten Fertigungsaufwand mit sich bringt.The invention relates to an arrangement for connecting a heating coil end with a connection screw, especially for electric water heaters. Until now you have soldered the heating coil ends to the connection screw. Soldering this one Resistance material used is known to cause difficulties and leads often to electrically and mechanically unsafe connections. Therefore one is multiple went over to bending the heating coil end into an eyelet and using a nut and lock nut to the connection screw, in case of frequent temperature changes Such clamp connections can loosen despite a nut lock and become unsafe Give contacts. It is also known that the heating coil end in a groove or a Pinch the slot of the connection screw. There is also a milling operation for slotting or grooves of the connection screw required, the undesirable manufacturing effort brings with it.
Demgegenüber besteht die Erfindung darin, daß das Heizwendelende in eine axiale Bohrung eines an die Anschlußschraube angedrehten Zapfens eingeführt uhd mit diesem zusammen winklig verpreßt ist.In contrast, the invention consists in that the heating coil end in introduced an axial bore of a pin screwed onto the connecting screw uhd is pressed together at an angle with this.
Es läßt sich auf diese Weise eine sowohl mechanisch als auch elektrisch einwandfreie Verbindung zwischen der Anschlußschraube und dem Heizwendelende bei geringstem Fertigungsaufwand herstellen.It can be both mechanically and electrically in this way perfect connection between the connection screw and the heating coil end Manufacture with the least amount of manufacturing effort.
Bekannt ist es, am Ende eines verseilten Leiters (Litze) eine flache
ketallhülse durch mehrfache Kerbung zu befestigen. Bei der Erfindung handelt es
sich jedoch um die unmittelbare Verbindung einer Anschlußschraube mit einem nicht
verseilten steifen Draht-
Abb. 1 zeigt eine Anschlußschraube 1 mit einem angedrehten und einer axialen Bohrung 3 versehenen Zapfen 2. In die Bohrung 3 wird ein gerades Heizwendelende 4 eingeschoben und, wie in Abb. 2 und 3 dargestellt ist, zusammen mit dem Zapfen 2 winklig verpreßt. Der Querschnitt des Heizwendelendes 4 bleibt dabei erhalten. Es wird eine große Flächenberührung zwischen Zapfen 2 und Heizwendelende 4 erreicht, so daß praktisch kein Ubergangswiderstand entsteht. Die Anschlußschraube 1 mit dem angedrdhten und axial gebohrten Zapfen 2 kann als Automatendrehteil hergestellt werden.Fig. 1 shows a connection screw 1 with a screwed on and one axial bore 3 provided pin 2. In the bore 3 is a straight heating coil end 4 and, as shown in Fig. 2 and 3, together with the pin 2 pressed at an angle. The cross section of the heating coil end 4 is retained. A large surface contact is achieved between the pin 2 and the heating coil end 4, so that there is practically no contact resistance. The connection screw 1 with the Angedrdhten and axially drilled pin 2 can be manufactured as a machine turned part will.
