Abstract:
Electrical connector for supplying current to electronic circuits. The connector comprises a flat metal bar and an insulating case (12) having an open cavity (16) extended by an inclined support (18) covered by an end portion (20) of the bar.
Abstract:
The invention concerns a device for a shielding connection (10) between a protective enclosure case (12) of a high voltage apparatus (14) and a shielded cable (20) comprising at least two conductors (22, 24) and a tubular shielding braid (26) enclosing said conductors. The device comprises a rotating ferrule (20) including one first cylindrical end (34) and a second end (36) with a rotating ring-shaped rib (38) with a shoulder (40) facing the direction opposite to the first end (34),said rib (38) external diameter being larger than said opening (28), a clamp collar (46) maintaining said braid (26) and said ferrule (32), and an arc-shaped elastic retaining ring (54) extending over an angle with a centre of at least 200 DEG , said collar (46) being designed to co-operate with stop means (62) integral with said second ferrule (30) end (36). The invention is applicable to shielding connection between a discharge lamp and a high voltage generator.
Abstract:
The invention concerns an electric cable end provided with a filter. In a preferred embodiment, the end of the cable (20) is not coated. The two isolated conductors (24, 26) pass through a ferromagnetic material (32). The end part of the coating and the ferromagnetic piece (32) are covered with an insulating material (38).

Abstract:
The invention concerns a rear connection device for a screened cable connector, said device comprising a sheath having an external diameter (D1), one or a plurality of screening braids with a diameter (D2) and a plurality of electrical leads. The device further comprises: a part (54) for continuing the screening, with a sleeve (70) having an external diameter substantially equal to D2 for securing the braiding, a first support section (76) and an axial bore (78) through which the electrical leads can be passed; a securing part (52) defining a cavity which is open at a first end (60) for securing to the connector and closed by a wall (58) defining a second bearing section (64) inside the cavity and having an axial aperture (62) whose diameter is at least equal to D1, the screening continuation part being able to penetrate the cavity freely; and a nut (56) for rendering the continuation part and securing part integral with each other.
Abstract:
A method for continously producing an electrical conductor made of an at least partially aluminium-based central core coated by continuous electroplating with at least one metal layer, including core surface pre-treatment, characterised in that it comprises the steps of (a) electrochemically copper-plating the core in an aqueous bath held at a temperature of 20-60 DEG C and containing KCN, CuCN, K2CO3 and KNaC4H4O6 with a current strength of 1-10 A/dm ; (b) rinsing at room temperature; (c) electrochemically tin-plating the core in an aqueous bath held at a temperature of 20-60 DEG C and essentially containing tin dissolved in methane sulphonic acid as well as optional additives, with a current strength of 1-100 A/dm ; and (d) rinsing in water at 60 DEG C.
Abstract:
L'invention concerne un dispositif de raccordement d'au moins une tresse de câbles électriques sur un raccord. Le dispositif comprend d'une part une chape (30) munie d'une fente et d'autre part une bande métallique (24) d'épaisseur et de largeur constantes. L'extrémité (28) de la bande (24) est repliée sur un bord (34) de la chape (30) tandis que l'autre extrémité (26) de la bande (24) passe deux fois dans la fente pour former deux spires (42, 44) autour de la tresse (38). L'extrémité (26) est ultérieurement repliée sur le rebord (36) de la chape (30) et coupée.
Abstract:
L'invention concerne un procédé de réalisation de câble formant élément de calibrage pour la mesure de l'impédance de transfert de câbles, et un câble élément de calibrage. Le câble formant élément de calibrage comprend une âme (12), une couche diélectrique (14), un blindage (16) et une gaine de protection (18). Selon l'invention, le blindage (16) a une épaisseur comprise entre 10 et 100 micromètres et il est réalisé de préférence par un dépôt de cuivre par voie chimique et un dépôt de cuivre par électrolyse.
