Connector devices or connectors for use in interconnection to a circuit board may be configured in an open or closed configuration. The connectors devices may utilize a shape memory alloy (SMA) actuator to move clamping portions with respect to each other into one or both of the open or closed positions.

A system and apparatus for increasing connectivity of a circuit board comprising a connector, wherein the connector has a horizontal body and a hollow cylindrical portion extruding vertically from the body; wherein the cylindrical portion is made up of a set of pieces; wherein at least a piece of the set of pieces is arranged to expand horizontally, upon insertion of a phalanx head in a vertical manner. A method to increase current connectivity comprising screwing a fastener into threads of a connector through a hollow cylindrical portion of the connector; wherein the hollow cylindrical portion of the connector is made up of a set of pieces; wherein the screwing causes a phalanx head to contact the cylindrical portion expanding at least one piece of the set of pieces in a horizontal manner in relation to the fastener.

An apparatus can dynamically adjust, in a card edge connector including first and second positions, an opening configured to receive a printed-circuit card. The apparatus may also include a set of contacts configured to connect with a set of edges of the printed-circuit card in the second position. The apparatus may also include a set of electroactive polymers configured to adjust the set of contacts between the first position and the second position by changing thickness in response to voltages applied to electrodes positioned adjacent to opposing faces of the set of electroactive polymers. The set of electroactive polymers can also include an electroactive polymer configured to control a single contact of the set of contacts.
