Abstract: The invention relates to a method for the joining, to a first conductor that includes a connector, of a second conductor formed by at least one strand made of aluminium or an aluminium alloy and having at least one end, the shape of which allows it to be introduced into the connector of the first conductor. The method has a step of installing the conductors, with the end of the second conductor being inserted into the connector of the first conductor. There is a magnetostriction step which has an electrodynamic force being generated in the connector so that the connector is crushed around the second conductor introduced into the connector. The subject of the invention is also a magnetostriction-generating device. In particular, the invention applies to the connecting-up of energy networks on all (for example, aerospace) carriers and equipment, with high-current and/or long links. The invention may also apply to connections suitable for information transmission on general-purpose conductors.
