Abstract:
A solenoid includes a magnetic frame, a bobbin having a length, a hold coil, a pick up coil having a length, a fixed pole, a movable armature having a length, and a return spring biasing the armature away from the pole. The solenoid includes a pick up state when the armature and the pole are separated by a magnetic gap, and a holding state when the armature and the pole are proximate each other. The pick up coil is wound around the bobbin for a portion of the length of the bobbin and the hold coil is wound around the bobbin for a remaining portion of the length of the bobbin. The length of the pick up coil is about the same as the length of the armature and is less than the length of the bobbin.

Abstract:
The invention seeks to provide bonded (equipotential) connections between the various parts of a current return network. To do this, the invention provides a wiring loom with a layer of conductors coated in a fluidtight jacket. Such a wiring loom (30) is able to connect structural metallic components in a volume available between a protective structure and a transverse frame made of carbon composite material or a cabin lining. In one embodiment, it comprises conductors (51) laid in parallel to form a flat and flexible layer (50), multipoint modular end connectors (32) and multipoint modular intermediate connectors (34), a protective jacket made up of an external jacket (60) which in portions (60T) covers the loom and a common jacket (62) which in portions (62T) covers the edges (32b, 34b; 60b) of the connectors (32, 34) and of the outer jacket (60). Openings (54, 56) are formed in the connectors (32, 34) for fixing means. The conductors (51) are fixed individually into the connectors (32, 34) and are coated with sealant inside a heat-shrink sleeve (46) in the region of the connectors (32, 34).
Abstract:
L'invention vise à réaliser des liaisons équipotentielles électriquement performantes en termes de résistivité entre des parties de réseau de retour courant d'une architecture non conductrice telle qu'un fuselage d'avion. L'approche suivie par l'invention est de conférer à un câble de grosse section en aluminium une fonction de type liaison équipotentielle, cette liaison étant raccordée électriquement par contact direct à autant d'équipements qu'il est physiquement possible d'en connecter. Selon un mode de réalisation, un ensemble de raccordement électrique d'un fuselage d'aéronef (100) à peau composite comporte des raccords de dérivation en ligne (2) d'interconnexion électrique entre un câble (1) de forte section à base d'alliage d'aluminium, servant de liaison équipotentielle via des raccords (202) à des supports (113, 141 ) de réseaux primaires de retour de courant, et des supports (111) d'équipements électriques. Chaque raccord de dérivation en ligne (2) comporte un manchon central (2m) de contact électrique direct avec le câble (1), des portions d'extrémité, d'assemblage au câble (1) par sertissage et un moyen de fixation (2p) pour venir se fixer au support (111) de l'équipement. Les extrémités du manchon (2m) logent chacune un joint d'étanchéité. Chaque interconnexion présente deux zones étanches qui entourent une zone de contact centrale par un dénudage en fenêtre.
Abstract:
The invention relates to sections of cable ends which are stripped of their individual shield coatings, so that they form single shield plies (2) extending from an end portion of the unstripped strand (1) around which a strip of conductive padding (6) is wrapped until it reaches a predetermined diameter. The plies (2) are rolled up and distributed evenly over the circumference of the end portion of the strand (1), in successive rollings of the padding strip (6). The padding strip (6) is inserted using a ring-shaped reinforcing spring blade (7), all of which is then enclosed between two half-shells which are fastened to each other and connected to the connector.

Abstract:
A method for thermally and mechanically protecting cables and cable harnesses with a sheath braided directly around the element to be protected by means of a braiding thread made of a number of basic strands formed by twisting together synthetic fibres produced by cracking and spinning an aramid fibre and a carbonisable oxidised organic fibre. The carbonisable oxidised organic fibre forms most of the synthetic fibres in the basic strand of the braiding thread. The resulting thermal and mechanical cable and cable harness protection sheath is also disclosed. Some of the mechanical or thermal properties of said sheath may be improved by combining an additional thread material with said two synthetic fibres to form the basic strands, or by covering the braided sheath with a complementary aramid fibre-based braid.
Abstract:
Various electrical connectors (11, 12) include conductor elements (25-28) extending through a support body (19, 20) in parallel insulated relation to one another and to adjacent grounds (17, 18) of very low inductance and resistance. The relationship of the conductor elements (25-28) to the planar grounds (17, 18) is such as to obtain a characteristic impedance which is the same for all signal paths and which is uniform along the length of each conductor element.
Abstract:
Connector (10-15) are provided for propagation of electrical signals in a plurality of closely spaced propagation paths, such as between circuits connected to conductive pads of circuit boards (17-20), each circuit presenting a certain characteristic impedance at a pad connected thereto. For example, each connector (11) includes a plurality of resilient and electrically conductive signal-propagating interconnect means (52, 54) having opposite ends engageable with conductive pads on a pair of the circuit boards. The interconnect means are supported by insulating means (30) of a support structure which also provides conductive ground means (49) adjacent relation to the conductive interconnect means. The conductive ground means are arranged for connection to grounding elements of the circuit boards. The configuration and characteristics of the ground conductor means and the insulating means in rlation to each signal-propagating interconnect means are such as to obtain a certain characteristic impedance for matching the characteristic impedances of circuits interconnected by each signal-propagating interconnect means.
