Abstract: A connection device includes a conducting element exhibiting a tubular portion and including a conducting sheath which is perforated with distributed perforations according to a predetermined solid-void pattern, the tubular portion and the sheath being configured in such a way that the sheath can be placed inside the tubular portion with the end section positioned inside the sheath and so that the tubular portion and the sheath can then be crimped onto the end section. The sheath includes at least one longitudinal wall separating two distinct housings each configured to accept one respective longitudinal portion of the end section of cable.
Abstract: Disclosed is a method of assembling a connecting device (3) on a stripped end section (6) of an electric cable (4), the method including a first step of crimping a first zone (40) of a tubular portion (13) of the device with a first portion (43) of the section that is configured so that the first portion has a first predetermined degree of compression; a second step of crimping a second zone (41) of the tubular portion with a second portion (44) of the section that is configured so that the second portion has a second predetermined degree of compression lower than the first degree; a step of punching a third zone (42) of the tubular portion with a third portion (56) of the section which is configured so that the third portion has a third predetermined degree of compression higher than the first degree.

Abstract: The object of the invention is to produce equipotential connections that are electrically efficient in terms of resistivity between portions of a current-return network in a non-conductive architecture, such as an airplane fuselage. The approach adopted by the invention is to impart an equipotential-bonding function to an aluminum cable having a large cross section, said bond being electrically connected, via direct contact, to as many devices as is physically possible to connect thereby. According to one embodiment, an electrical connection assembly of an aircraft fuselage (100) having a composite skin comprises in-line shunt connections (2) for electrically interconnecting an aluminum-alloy-based cable (1) of large cross section acting as an equipotential connection to brackets (113, 141) for primary current-return networks and to brackets (111) for electrical devices via connectors (202).

Abstract: A wire clamp for earthing a metal structure includes a body (10) having a tapped cylindrical cavity opening at a first end of the body, the other end being closed by a bottom (12) pierced with a hole (13) for the passage of a screw (20) for fastening the body onto metal structure, the body having over at least a part of the tapped cavity two through-slots facing each other that are formed along two generatrices of the cylindrical cavity and opening at the first end and a threaded plug (30) having a formation for rotational driving and adapted to helicoidally engage in the tapping of the cylindrical cavity to clamp a core of an electrical wire against the bottom of the slots, the plug having a central through-hole (32) adapted to allow passage of a tool for rotationally driving the screw for fastening the body onto the metal structure.
Abstract: The terminal for electrical connection includes a pin (2) with a recess (9), partially filled with a contact grease, to accommodate the end of an electric cable (22) and including a crimping section (5) designed to be radially deformed and further includes a stopper (15) to retain the grease (14) in the recess (9). The stopper has a transverse membrane (16) designed to be broken by the electric cable (22) on insertion thereof into the recess (9) and at least one portion arranged in the crimping section (5) such that the stopper (15) leads to the sealing of the connection after crimping. The grease (14) is arranged between the base (12) of the recess (9) and the membrane (16). The assembly method includes the step of breaking the transverse membrane (16) by element of the end of the electric cable (22) on insertion thereof in the recess (9).
