Abstract: Multiple-contact electrical connectors comprising in particular a base 1, two pairs 2, 3 of input/output terminals 4-6, two electrically conductive needles 11, 12, two electrically insulating plates 21, 22 having orifices 31-34, the needles being slidably mounted relative at least to the plate 22, and means for fixing the two plates 21, 22 relative to the base 1. The connector further comprises: at least two other plates 23, 24 positioned between the two plates 21, 22 and in which orifices 41-44 are formed, the needles being slidable in the orifices 41-44; and elements for causing the plates 23, 24 to move respectively in two substantially opposite directions so as to impart two pre-buckles 61-64 to each needle in opposite directions on either side of its rest position. The invention is applicable in particular to connectors for making an electrical connection between a test device and electronic components such as chips, for example.

Abstract: The present invention relates to multiple-contact electrical connectors comprising in particular a base 1, two pairs 2, 3 of input/output terminals 4-6, two electrically conductive needles 11, 12, two electrically insulating plates 21, 22 having orifices 31-34, the needles being slidably mounted relative at least to the plate 22, and means for fixing the two plates 21, 22 relative to the base 1. The connector of the invention is essentiially characterized by the fact that it further comprises: at least two other plates 23, 24 positioned between the two plates 21, 22 and in which orifices 41-44 are formed, the needles being slidable in the orifices 41-44; and means 50 for causing the plates 23, 24 to move respectively in two substantially opposite directions so as to impart two pre-buckles 61-64 to each needle in opposite directions on either side of its rest position.

Abstract: A pipe connector, in particular for high-purity gases and ultra-high vacuum or high-pressure systems, is provided with two end-pieces each having a coupling extremity. The connector is also provided with a special seal and a sleeve for maintaining the two end-pieces in the line of extension of each other in a first stage of assembly. Two half-shells are provided for longitudinal locking of the connector in a second stage of assembly.

Abstract: Each end fitting of the union has an end for fixing the fluid line, and a coaxial metallic body terminating in an annular radial polished section where the internal bore of the union issues. A washer made of a deformable synthetic material is pressed on this metallic body and has a flat annular radial face which, together with the polished section, forms the free face for connecting the end fitting. A cylindrical metallic ring accommodates internally with a contact fit the two washers and a portion of the two metallic bodies, so that the two free connecting faces come to be opposite each other. Two clamping half-shells grip the two end fittings to ensure the connection of the fluid lines.
