An electrical connector has a series of terminals therein each with a tongue that projects from the connector, the tongue being soldered to a circuit board. The connector has depending ledges which support an edge portion of the circuit board remote from the soldered connection to resist rupture of the soldered connection upon bending of the circuit board. In another arrangement a circuit board has pin conductors and a lock wafer adjacent to the board and through which the pins project and are secured. The pins also are adapted to project into the connector for connection with the terminals. The lock wafer has a flexible lip that engages a shoulder on the connector to prevent separation of the circuit board and connector.
