Publication number: 20060288568Abstract: A device for fabricating an insulating material cellular sheath around a conductor. The device has a central guide including a longitudinal passage adapted to receive the conductor. The fabrication device further has a peripheral guide, an internal surface of the peripheral guide and an external surface of the central guide defining a passage adapted to receive the insulating material in a viscous state. The fabrication device further maintains a sleeve separate from the central guide and the peripheral guide. At least a portion of the sleeve is adapted to be placed between the central guide and the peripheral guide and includes an opening that opens onto the central guide and onto the peripheral guide.Type: ApplicationFiled: August 11, 2005Publication date: December 28, 2006Inventors: Pascal Clouet, Jean-Francois Guinot

Patent number: 5922155Abstract: A method of manufacturing an insulative material cellular insulator around a conductor, the insulator having a longitudinal passage in which the conductor is housed and closed cells extending longitudinally and separated from each other by radial walls, includes the following operations: the insulative material in the viscous state is extruded to impart the required shape to it to form the cells, the insulative material shaped in this way is applied to the conductor, and the insulative material is cooled to obtain the insulator. The insulative material is applied to the conductor at a distance from the exit of the shaping device such that the material is drawn down sufficiently for the walls of the cells not to be thinned without pressurizing the cells.Type: GrantFiled: April 22, 1997Date of Patent: July 13, 1999Assignee: FilotexInventors: Pascal Clouet, Jean-Jacques Maisseu, Francois Vaille, Alain Vernanchet

Patent number: 5414212Abstract: The herringbone harness has multiple branches leading off from a trunk divided into segments by the forks at which the branches start. The harness is exclusively shielded firstly by first braids made over the individual branches, each first braid having a first enlarged tab over at least one of the segments on either side of the branch in question, and secondly by second braids made over the individual segments, each second braid having a second enlarged tab over that adjacent segment which is of smaller diameter than the segment in question. The application is a shielded harness serving multiple points from a common point of origin.Type: GrantFiled: January 27, 1993Date of Patent: May 9, 1995Assignee: FilotexInventors: Pascal Clouet, Francois Vaille, Andre Viaud

Patent number: 5295868Abstract: A pre-equipped shielded harness has at least one end portion formed of a bundle of twisted-together conductors covered by a shielding braid. The harness includes an expander having cross-sectional dimensions substantially identical to those of a rear of a connector to be connected to the end portion. The expander is positioned at the location at which the connector is to be connected, and is covered by the shielding braid by preforming the shielding braid over the expander. The shielded harness has high magnetic protection.Type: GrantFiled: January 27, 1993Date of Patent: March 22, 1994Assignee: FilotexInventors: Andre Viaud, Pascal Clouet
