US Patent 10182509 Wedge clamp for circuit board

A wedge clamp is provided. The wedge clamp includes wedge members aligned with a shaft and in sliding contact with surfaces of the neighboring wedge members. Some of wedge members each include a finger and a void, with the finger of a first member slidably inserted within the void of a second wedge member and vice versa. The fingers and voids extend at an acute angle, and the fingers and voids of other wedge members extend at another acute angle on an opposite side of a vertical axis. When the shaft is rotated some wedge members vertically translate with respect to the remaining wedge members. When the shaft is rotated in the reverse direction the wedge members translate vertically in the opposite direction returning to an original position. The interaction of the fingers and voids mechanically drive the moved wedge members into the original state.
