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. Further, the edge clip may include a center beam extending away from one of the opposing surfaces to provide contact with another metallic surface, such as a miniature card case, thereby providing additional grounding capabilities which can provide protection against static discharge.

Claims

1. A vertically installed edge clip for use with a printed circuit board having an edge and a surface portion, at least two locating holes of predetermined diameter being formed in the surface portion, consisting of:

a planar body section having first and second distal ends;

a planar edge section disposed on said first distal end of said planar body section, said planar edge section offset at a predetermined angle relative to said planar body section;

at least first and second lead sections disposed on said second distal end of said planar body section, said at least first and second lead sections offset at a predetermined angle relative to said planar body section,

said edge clip being vertically mounted on the printed circuit board by inserting said at least first and second lead sections in the at least two locating holes in the surface portion of the printed circuit board such that said planar edge section is proximate to the edge of the printed circuit board, said at least first and second lead sections facilitating maintaining proper alignment of said edge clip with respect to the printed circuit board.

2. The edge clip of claim 1 wherein said first and second lead sections are arranged approximately perpendicular to said planar body section.

3. The edge clip of claim 2 wherein said first and second lead sections decrease in width at respective distal portions thereof.

4. The edge clip of claim 2 wherein said planar edge section is approximately perpendicular to said planar body section.

5. The edge clip of claim 4 wherein said first and second lead sections are secured to the printed circuit board by solder.

6. The edge clip of claim 4 wherein the printed circuit board includes a conductive pad disposed on the surface thereof between at least one of said locating holes and the edge, and said planar body section is adhered to the conductive pad by solder.

7. The edge clip of claim 4 wherein said edge clip is stamped from a plated copper sheet.

8. The edge clip of claim 1 having at least one planar surface which can be held by a suction device of a pick and place machine for surface mount installation.
