Abstract

The production method for terminal connectors or inter-connectors for the connection of Cu- with Al-conductors of electrical lines producing a superior compound structure between the two metals is achieved by that both connector parts are joined by cold welding or friction welding. An intimate intermolecular union results between the two parts. Large temperature variations such as caused by current flow or sun radiation or by strong under-cooling do not destroy or reduce the conductive properties of the joint. Pre-fabricated terminal or interconnector parts of the same metal, i.e. Al to Al or Cu to Cu, may also be cold welded or friction welded with the same result.

Description

Verfahren zur Herstellung von Anschluß- oder Verbindungs-Klemmen für Kupfer- und Aluminium-Leiter für elektrische Verbindungen Die Erfindung betrifft ein Verfahren zur Herstellung von Anschluß- und Verbindungsklemmen aus Aluminium und Kupfer für elektrische Verbindungen. Process for the production of connecting or connecting terminals for copper and aluminum conductors for electrical connections The invention relates to a process for the production of connecting and connecting terminals made of aluminum and copper for electrical connections.

Bei bisher bekannten Verfahren dieser Art wird der Kupfer-Anschluß mit einem Bolzen in das vorgearbeitete Aluminium-Anschlußteil eingeschraubt, eingepreßt oder der Bolzen des Kupferanschlusses mit Aluminium umgossen und ggf. aus Sicherheitsgründen noch verstiftet. Zwecks Verhütung von Korrosion wird die Obergangsstelle entweder lackiert oder an der Obergangsstelle außen äuf andere Weise isoliert.In previously known methods of this type, the copper connection screwed into the pre-machined aluminum connection part with a bolt, pressed in or the bolt of the copper connection is encased with aluminum and, if necessary, for safety reasons still pinned. In order to prevent corrosion, the transition point is either varnished or otherwise insulated on the outside at the crossing point.

Diese mechanischen Verbindungs-Verfahren haben den Nachteil, daß sich infolge der unterschiedlichen Wärmedehnungs-Koeffizienten zwischen Kupfer und Aluminium bei Temperatur-Schwankungen, Stromerwärmungen odgl.These mechanical connection methods have the disadvantage that due to the different coefficients of thermal expansion between copper and aluminum with temperature fluctuations, current heating or the like.

im Laufe der Zeit Haarrisse bilden, die das Eindringen von Feuchtigkeit durch Kapilarwirkung zwischen beiden Metallen erlauben und damit Anlaß zu Korrosionserscheinungen geben, die die Stromübertragung verringern.Over time, hairline cracks form, allowing moisture to penetrate allow through capillary action between the two metals and thus give rise to signs of corrosion that reduce the power transmission.

Auch die oben erwähnten Korrosions-Schutzmaßnahmen lassen diese Erscheinung nicht vermeiden.The above-mentioned corrosion protection measures also leave this phenomenon behind do not avoid.

Der Erfindung liegt die Aufgabe zugrunde, ein wie oben erläutertes Verfahren zu schaffen, bei dem diese Nachteile mit Sicherheit nicht auftreten, sondern in jedem Fall ein hervorragender Verbund beider Metalle erzielt wird. Dies wird erfindungsgemäß dadurch erreicht, daß beide Anschluß-Elemente durch Kaltschweißen oder Reibschweißen verbunden werden. Auf diese Weise entsteht eine innige intermolekulare Verbindung zwischen beiden Teilen. Selbst durch stark wechselnde Wärmeschwankungen, sei es durch Stromwärme, Sonneneinstrahlung, oder starke Unterkühlung wie aggressive atmosphärische Umwelteinflüsse wird der Verbund nicht zerstört. Durch Kaltschweißen bzw. Reibschweißen können auch vorgefertigte Anschluß- oder Verbindungsklemmen für elektrische Leitungen vom gleichen Werkstoff Aluminium zu Aluminium bzw. Kupfer zu Kupfer verbunden werden.The invention is based on the object as explained above To create a process in which these disadvantages do not occur with certainty, but rather In any case, an excellent bond between the two metals is achieved. this will according to the invention achieved in that both connection elements by cold welding or friction welding. In this way an intimate intermolecular arises Connection between the two parts. Even with strongly changing heat fluctuations, be it through electricity heat, solar radiation, or strong hypothermia such as aggressive the network is not destroyed by atmospheric environmental influences. By cold welding or friction welding can also use prefabricated terminals or connecting terminals for electrical cables made from the same material aluminum to aluminum or copper be connected to copper.

Die Erfindung sei an 2 Beispielen anhand der Zeichnungen näher erläutert: Es zeigen: Figur 1) eine Anschluß- bzw. Verbindungs-Klemme in Vorderansicht als auch Draufsicht Figur 2) eine kombinierte Anschlußklemme mit Preßhülse ebenfalls in Vorderansicht und Draufsicht.The invention will be explained in more detail using 2 examples based on the drawings: They show: FIG. 1) a connecting or connecting terminal in a front view as also top view Figure 2) a combined terminal with compression sleeve also in front view and top view.

Als wesentlich ist in beiden Figuren der Verbund 1 zu betrachten, der beide Klemmteile 2,3 + 4 miteinander mittels Kaltschweißen bzw.The composite 1 is to be regarded as essential in both figures, the two clamping parts 2, 3 + 4 together by means of cold welding or

Reibschweißen verbindet.Friction welding connects.

Bei Figur 2) bedeutet das Klemmenteil 2 + 4 die gleiche Verbindungsart, nur das der Teil 4 als Preßhülse zum Verpressen des elektrischen Anschlußleiters ausgebildet ist. Die Hülse kann aber auch mit Innengewinde versehen werden, um sie auf einen Schraubenbolzen anzuschließen.In Figure 2) the terminal part 2 + 4 means the same type of connection, only the part 4 as a compression sleeve for pressing the electrical connection conductor is trained. The sleeve can also be provided with an internal thread to it to connect to a screw bolt.

Mit 5 + 6 sind schließlich noch übliche und notwendige Klemmdeckel und Schrauben bezeichnet.Finally, with 5 + 6 there are still common and necessary terminal covers and screws.
