Abstract
Abstract A surface mount connector comprises an insulating housing body in which a series of electrical contacts are secured with contact leg portions thereof extending externally alongside a housing face and a contact aligning member for assembly with the housing by forcible insertion between the housing face and the contact leg portions thereby urging the contact leg portions away from the housing face to bring contact ends thereof into a common circuit board engaging plane and a predetermined spaced apart relation. The guide means comprises an insulating bar formed with a row of ribs defining between them contact receiving alignment channels at the predetermined spacing. Ears extend from the housing face at respective opposite ends of the series of contacts and have respective recesses aligned with each other and the contact leg portions for receiving the aligning member as a force fit to assemble the aligning member with the housing.
