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.
