US 2008/0156055 A1 · METHOD FOR JOINING ELECTRICAL CONDUCTORS BY MAGNETOSTRICTION AND MAGNETOSTRICTION-GENERATING DEVICE

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.

A method for the joining, to a first conductor that includes a connector, a second conductor formed by a 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, comprising the following steps:

a step of installing the conductors, the end of the second conductor being inserted into the connector of the first conductor;
and
a magnetostriction step, an electrodynamic force being generated in the connector so that said connector is crushed around the second conductor introduced into the connector.

A magnetostriction-generating device suitable for joining, to a first conductor that includes a connector, a second conductor formed a 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, comprising:

an induction loop generating a magnetic field, the induction loop being designed to couple said magnetic field to the deformable part of the connector, the shape and the dimensions of the loop being suitable for holding the deformable part in place;
an inductor connected via a fourth switch to a voltage generator, to a current generator and to a third switch which makes it possible to select whether the inductor is connected to the current generator or to the voltage generator;
an AC current generator coupled to the inductor and to the induction loop via a transformer, a first switch being placed in parallel with the AC current generator;
and
a circuit comprising a second switch and a capacitor in parallel with the inductor.
