Abstract: A method electrically connects by crimping electrical conductors in a connector for equipotential connection of a planar and flexible layer formed by the conductors, to metal components. The method includes positioning the electrical conductors in individual longitudinal and parallel cells which are formed between two planar walls of the connector, crimping the conductors crimped in a crimping zone by simultaneous transverse punching of at least one wall of the connector, and forming by the transverse punching at least one corresponding transverse groove line on the at least one connector wall and, by load transfer, on each of the conductors to electrically connect the conductors.

Abstract: A connection which is reproducible, uniform and reliable both for intermediate and terminal connections of a conductor layer wiring loom, by making provision for simultaneous crimping of the conductors in connectors by applying continuous and uniform pressure in a crimping zone. The crimping is carried out by a tool including two shells, each shell including a main wall that forms an inner face including transverse ribs and end edges folded over perpendicularly relative to the walls to define an inner space. In the inner space, a connector of non-insulated conductors arranged perpendicularly relative to the ribs is introduced to form transverse grooves by compression of the ribs on the walls of the connector. The tool can find use in current return networks of aircraft passenger cabins having composite skin.
