An electrical connector for connecting a sheet-like member includes a housing (1) defining an insertion slot (10); a plurality of terminals (2) arranged in the housing in parallel relationship with a predetermined pitch, each of the terminals having a contact beam (22) extending into the insertion slot and a pivot beam (21) extending substantially parallel to the contact beam; and an actuator (3) rotatably provided for establishing an electrical connection between the sheet-like member and the contact beams. The actuator provides cam portions (31) each interposed between every other the pivot beam. Each of the cam portions provides shaft portions (32) respectively adapted for pivotably engaging with the pivot beams disposed therebeside. The shaft portions extending towards each other respectively from two adjacent cam portions are spaced to define a gap (33) therebetween.
