Abstract: A DC-DC voltage converter including a main switch formed by a normally ON switch element connected in series with a normally OFF switch element including a control circuit, a load in series with the main switch, the main switch and the load being configured to be connected to terminals of a DC voltage source. A voltage source, that can be used for controlling is obtained by connecting a main peak detector circuit to the mid-point of the main switch. The control circuit of the normally OFF switch element can be supplied with the DC voltage that makes the entire device self-supplied. Such a converter can, for example, find application in aeronautics.

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.

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). Each in-line shunt connector (2) comprises a central sleeve (2m) for directly electrically contacting the cable (1), end portions for installation on the cable (1) by crimping, and an attachment means (2p) for attaching to the bracket (111) of the device. Each of the ends of the sleeve (2m) have a seal accommodated therein. Each interconnection has two sealed regions, which surround a central contact region formed by means of window-stripping.
