Cable connector incorporating anisotropically conductive elastomer
View Patent ↗A separable electrical connector for separably, electrically interconnecting the conductors of one multi-conductor cable to the conductors of a second electrical device that may be an electrical device such as a chip, or a second multi-conductor cable, or a flexible or rigid printed circuit board. The connector includes a layer of anisotropic conductive elastomer (ACE) in electrical contact with the conductors of the cable and the conductors of the second electrical device. A clamp or another type of mechanical device compresses the ACE, to provide electrical signal paths between the conductors of the cable and the second electrical device, through the ACE.
1. A separable electrical connector for separably, electrically interconnecting the conductors of one multi-conductor cable to the conductors of a second multi-conductor cable, comprising:
at least two multi-conductor cables, each cable having a plurality of at least partially-exposed conductors, with the exposed conductors of two of the cables in proximity to one another, at least one such cable being a multi-axial cable comprising at least two spaced coaxial conductors;
anisotropic conductive elastomer (ACE) in electrical contact directly with the exposed conductors that are in proximity to one another; and
mechanical structure that holds at least the multi-axial cable and compresses the ACE, to provide electrical signal paths between the conductors of the cables that are in proximity to one another through the ACE.
2. The electrical connector of claim 1 in which at least one cable is a ribbon cable.
3. The electrical connector of claim 1 in which at least one cable is a flex cable.
4. The electrical connector of claim 1 in which two cables are multi-axial cables each comprising at least two spaced coaxial conductors.
5. The electrical connector of claim 1 in which the mechanical structure comprises a mounting sleeve coupled to at least one multi-axial cable.
6. The electrical connector of claim 2 , further comprising a paddle board having conductors that are directly connected to the conductors of the ribbon cable, with the ACE layer against the conductors of paddle board.
7. The electrical connector of claim 4 in which the ACE lies directly against the conductors of both multi-axial cables.
8. The electrical connector of claim 4 further comprising printed circuit boards with conductors directly connected to the conductors of each of the multi-axial cables, with the ACE layer against the conductors of both boards.
9. The electrical connector of claim 5 in which the mechanical structure further comprises a clamp assembly coupled to the mounting sleeve.
10. The electrical connector of claim 5 in which the mounting sleeve is made by potting the end of the at least one multi-axial cable in a settable medium.
