Abstract

The miniature contacts form a pluggable connector for small circuit bearing substrates for the purpose of connecting a series of such small substrates 10 to a larger mother board 11. Both contacts 12 and 13 are alike in shape and size and description of one applies to the other.

Miniature Pluggable Connector

The miniature contacts form a pluggable connector for small circuit bearing substrates for the purpose of connecting a series of such small substrates 10 to a larger mother board 11. Both contacts 12 and 13 are alike in shape and size and description of one applies to the other.

Contact 12 is formed as a sheet metal split cylinder with a U-shaped tab or terminal foot section 14 extending above shoulder 15. Tab 14 can either be crimped onto a wire, or forced into a board land area or soldered into a circuit land such as land 17. In the latter, tab 14 of contact 13 is attached to be electrically connected to conductor 18 on board 11.

Cylindrical contacts 12 and 13 are formed with split flexible free ends to be readily connected together by an axial thrust as noted by the arrows. This mode of connection is facilitated by the flared angle of entry 16, shaping the split in the end of each contact. As small board 10 is forced down to plug onto board 11, the position of contact 12 is offset to the left with respect to the position of contact 13 so that the contacts are forced together. The right wall of cylinder 12 is pinched by the split in cylinder 13.

The left wall of cylinder 13 is pinched by the split in cylinder 12.

The split edges are curled as at 19 (sectional drawing) to prevent the inner contact edges from gouging or scratching the contact walls.

The slight taper of the contacts causes a twisting action as they are connected.
