Patents by Inventor David M. Barnum

David M. Barnum has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7223105
    Abstract: 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.

  • Patent number: 7077659
    Abstract: A separable electrical connector for electrically interconnecting an electrical device to a substrate. The connector includes an adapter board electrically connected to the substrate, the adapter board having electrical contacts on both sides, and a layer of ACE between the electrical device and the adapter board. A mechanical structure is used to apply a compressive force on the ACE through the adapter board and the electrical device.

  • Patent number: 6802720
    Abstract: A pin-array, separable, compliant electrical contact member for separably, electrically interconnecting a first electrical device having electrical contacts to a second electrical device having electrical contacts. The inventive device includes a probe housing having a thickness, and defining a plurality of openings through the thickness, one or more pin probes, each pin probe located in and protruding from an opening in the probe housing, and each defining an enlargement larger than the opening in which the pin is located, to inhibit lateral pin motion, and also prevent the pins from being removed from their openings vertically in at least one direction, and a layer of Anisotropic Conductive Elastomer (ACE) adjacent to the probe housing and comprising a plurality of conductive chains of particles through the layer thickness and aligned generally perpendicularly to the layer's major surfaces.

  • Patent number: 6077095
    Abstract: An edge clip is disclosed for electrically connecting a conductive pad on the surface of a printed circuit board or its edge to an external connector. The edge clip is substantially U-shaped, with first and second opposing, non-parallel sides defining a space therebetween. For connection, the printed circuit board edge is fitted into the space such that the opposing sides provide spring-like deflective force against the pad and the printed circuit board, thereby providing a more reliable connection. The edge clip may include an alignment feature for facilitating alignment prior to soldering. The alignment feature may include small projections formed on the edge clip to align with, and fit into, holes on the print circuit board. Scored sections may be disposed on one edge of the clip to facilitate removal of the edge clip from a carrier during assembly.
