Edge mounted circuit board electrical connector

U.S. Patent Number: 5292265

Abstract: An electrical connector is provided for surface mounting along an edge of a circuit board in an edge straddling configuration. The circuit board has a plurality of contact pads spaced along opposite faces of the board near the edge thereof. The connector includes a dielectric housing and a plurality of terminals mounted on the housing with solder tails projecting from the housing generally in two rows to define an elongate board-receiving mouth for receiving the edge of the circuit board. The contact pads are adapted to receive soft solder paste thereon prior to insertion of the board into the mouth between the two rows of solder tails. The solder tails of the terminals are configured for receiving the circuit board at a first angular orientation wherein minimal contact force is effected between the solder tails and the contact pads to prevent any substantial wiping away of the solder paste from the contact pads and a second angular orientation wherein substantial contact force is effected between the solder tails and the contact pads in a direction generally normal to the faces of the circuit board. Therefore, the solder paste remains in an interface area at each contact pad and its respective solder tail.
