Abstract
In a gas discharge over-voltage arrester a welded connection is provided between electrodes thereof and connection wires preferably by means of long-time resistance welding of copper to copper. A respective peg with a diameter of approximately 9/10 and a length of approximately 6/10 of the diameter of the connection wire projects from the surfaces of the electrodes to be connected. The connection wire is welded blunt to the end surface of the peg.
Claims12
An electrical terminal connection system for electrodes of a gas discharge over-voltage arrester, comprising:
- an electrode of the arrester to be connected comprising a high current conductivity material;
- a connection wire comprising a high current conductivity material;
- a peg projecting from the electrode to be connected and having a diameter of approximately 9/10 and a length of 5/10 to 8/10 of the diameter of the connection wire;
- and
- an end surface of the connection wire being welded blunt to an end surface of the peg.
A method for attaching connection wires to electrodes of a gas discharge over-voltage arrester adapted for handling high currents, comprising the steps of:
- providing the electrode of the arrester to be connected with a high current conductivity material;
- providing a connection wire for connection to the electrode with a high current conductivity material;
- on the electrode providing a peg projecting therefrom having a diameter less than a diameter of the connection wire and a length of 5/10 to 8/10 of the diameter of the connection wire;
- and
- in a long-time resistance welding operation welding an end surface of the peg in blunt fashion to an end surface of the connection wire.
