Abstract
Abstract A microconnector with a high density of contacts which make it possible to connect N parallel electrodes to N electrical conductors. The microconnector comprises a support able to receive the electrodes, N electrically conductive, flexible, elastic wires, respectively connected to the N conductors and fixed to an insulating part movable relative to said support in such a way that the wires are parallel and each of them can come into contact with a single electrode as a result of a displacement of the insulating part when the electrodes are fitted in the support. A cam is provided for moving the part in such a way as to bring about simultaneous contacts between the respective electrodes and wires. The microconnector can be used in connection with flat screen display means.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
161 words
A microconnector for connecting N parallel electrodes to a plurality of N electrical conductors, comprising a support on which said conductors are fixedly mounted, said support being able to receive the N electrodes, a plurality of N parallel, flexible, elastic, electrically conductive wires respectively fixedly connected to the N electrical conductors and fixed to an electrically insulating part which is movable relative to the support such that when the electrodes are installed in said support, the wires and the electrodes are not in contact when the insulating part is in a first position, and the wires and electrodes are in contact when the insulating part is in a second position, and means for moving the insulating part from the first position to the second position without displacing said support relative to said electrodes, so as to bring about simultaneous contact between the N electrodes and the respective N wires, said moving means being mounted on and movable relative to said support.
Claim 2
Dependent Claim
161 words
A microconnector for connecting N parallel electrodes to a plurality of N electrical conductors, comprising a support on which said conductors are fixedly mounted, said support being able to receive the N electrodes, a plurality of N parallel, flexible, elastic, electrically conductive wires respectively fixedly connected to the N electrical conductors and fixed to an electrically insulating part which is movable relative to the support such that when the electrodes are installed in said support, the wires and the electrodes are not in contact when the insulating part is in a first position, and the wires and electrodes are in contact when the insulating part is in a second position, and means for moving the insulating part from the first position to the second position without displacing said support relative to said electrodes, so as to bring about simultaneous contact between the N electrodes and the respective N wires, said moving means being mounted on and movable relative to said support.
Claim 3
Dependent Claim
38 words
A microconnector according to claim 1, wherein the electrodes are arranged in several parallel, staggered rows on electrically insulating substrates, and the wires are also fixed to the part insulating following the same number of parallel, superimposed rows.
Claim 4
Dependent Claim
63 words
A microconnector according to claim 1, wherein the electrodes are arranged parallel to one another on the same electrically insulating substrate and form a periodic sequence of longitudinally displaced electrodes and the wires are also fixed to the insulating part, so as to form a periodic sequence of, staggered rows of parallel conductors which are transversely and longitudinally displaced relative to one another.
Claim 5
Dependent Claim
45 words
A microconnector according to claim 1, wherein the support is hollow and the electrical conductors are other electrodes disposed on an electrically insulating plate carrying at least one electronic microcomponent and located in the hollow support, said other electrodes being connected to the electronic microcomponent.
Claim 6
Dependent Claim
16 words
A microconnector according to claim 4, wherein the wires are directly connected to said other electrodes.
Claim 7
Dependent Claim
46 words
A microconnector according to claim 1, wherein the means for moving the insulating part comprises a cam mounted in rotary manner on the support and intended for bearing on said part, so as to be able to bring about contact between the electrodes and the wires.
Claim 8
Dependent Claim
27 words
A microconnector according to claim 1, further comprising resilient means able to exert a force on said insulating part for moving the wires away from the electrodes.
Claim 9
Dependent Claim
41 words
A microconnector according to claim 1, wherein the insulating part is also displaceable perpendicular to the electrodes when the latter are fitted in the support, so as to be able to regulate the position of the wires relative to the electrodes.
Claim 10
Dependent Claim
66 words
A microconnector according to claim 1, wherein the insulating part is connected to the support by resilient means, the electrodes are arranged on an electrically insulating substrate, and the microconnector further comprises an abutment fixed to the insulating part and able to prevent any contact between the wires and the substrate when said wires are in the connection position and the substrate strikes against the abutment.
Claim 11
Dependent Claim
56 words
A microconnector according to claim 1, wherein the electrodes are arranged on an insulating substrate and wherein the support comprises a cover, said cover being provided with means for fixing said substrate relative to the support and with a recess making it possible to observe at least the first or last of the plurality of wires.
Claim 12
Dependent Claim
15 words
A microconnector according to claim 1, wherein said wires are made from a copper-beryllium alloy.
Claim 13
Dependent Claim
52 words
A microconnector according to claim 1, wherein each of said wires has a substantially straight portion, said wires being arranged such that said substantially straight portions are substantially parallel and rotate relative to a fixed point when said moving means moves said insulating part from the first position to the second position.
