Abstract: A stop block system for locking hydraulic cylinders is provided. The stop block system includes a plurality of axially adjacent layers that are arranged co-axially. The layers include a top layer having a bearing surface for receiving a load, one or more spacer rings for adjusting the height of the stop block system and transferring the load from the top layer to a base layer and a base layer for centering the stop block system and transferring the load from the spacer rings to a surface on which the stop block system rests. Each annular layer may be made up of two or more annular c-shaped components. The two or more components of one layer may be rotationally offset from the two or more components of axially adjacent layers.

Abstract: An electrical connector includes a housing (12) and a coupling assembly (35) that has a mateable contact (32) at the front of the housing and a conductor-terminating coupling (34). The coupling has a pair of arms (38, 40) with jaws (48) that are biased toward an axis (37). A holder member (54) has a pair of projections (58, 60) with surfaces that hold the arms in a ready position wherein they have been resiliently deflected away from the axis. When a cable conductor (66) is inserted forwardly (F) through a bore (28) in the housing, the forward tip of the cable presses the coupling assembly forwardly. As the coupling assembly moves forward, the arms are released from the holder members, so the arms can move toward the axis and the jaws (48) on the arms can engage the cable conductor.
