Latest Patents

One of Barnum's latest patents is the Miniature Card Edge Clip. This invention is designed to electrically connect 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, featuring first and second opposing, non-parallel sides that define a space in between. For connection, the printed circuit board edge is fitted into this space, allowing the opposing sides to provide a spring-like deflective force against the pad and the printed circuit board. This design enhances the reliability of the connection. Additionally, the edge clip includes an alignment feature to facilitate proper alignment prior to soldering, which consists of small projections that fit into holes on the printed circuit board. Scored sections on one edge of the clip aid in the removal of the edge clip from a carrier during assembly. Furthermore, the edge clip may feature a center beam extending away from one of the opposing surfaces to contact another metallic surface, such as a miniature card case, providing additional grounding capabilities and protection against static discharge.
