ABSTRACT:
An edge connector for a printed circuit board includes a housing having a central passageway for guiding the board. Contact elements are rotatably mounted in cavities of the housing adjacent to the passageway. Cantilever spring-type conductive terminals resiliently urge the contact elements so that they partially extend into the passageway. In their normal position (that is, without a board inserted into the passageway) the contact elements are in interfering relationship with the path of the board. Upon insertion of a board the contact elements resiliently yield to the board. Such contact elements selectively roll over the edges and any surface irregularities of the board to minimize the force required to fully insert the board into the passageway of the housing and to minimize the wear of the board. Such contact elements also provide both a good mechanical and electrical connection to contact areas of the board.
