  • Patent number: 7128626
    Abstract: There is provided a hydraulic steering assembly for applying a force to two or more marine propulsion units. Each propulsion unit has a steering axis and a tilt axis. The tilt axis is generally perpendicular to the steering axis thereof. Each propulsion unit is rotatable about the steering axis and is supported for arcuate movement about the tilt axis thereof. The steering assembly comprises a hydraulic steering actuator including a cylinder and an elongated piston rod. The cylinder has a first end and a second end. The elongated piston rod is reciprocatingly mounted within the cylinder and extends through the cylinder for movement along a piston rod axis. A pair of support arms are pivotable about the tilt axis of a first propulsion unit. The support arms are connected to the piston rod axis allowing arcuate movement of the piston rod about the tilt axis, while maintaining the piston rod axis parallel to the tilt axis.

  • Patent number: 5913698
    Abstract: A connector includes an insulative housing (18), a plurality of contacts (23), a first shell (27), a second shell (38) and a grounding plate (44). The insulative housing (18) has a cubic body defining plural surfaces wherein a socket section (19) is disposed on one of such surfaces surrounded by an annular slot (20). A plurality of passageways (21) extend into the socket section (19). The first shell (27) and the second shell (38) commonly cover the most portions of the external surfaces of the body. The first shell (27) includes a pair of locking sections (35). A grounding plate (44) is adapted to be attached to the connector wherein the grounding plate (44) includes a pair of locking tags (49) for engagement with the corresponding locking sections (35) of the connector, respectively. The grounding plate (44) further includes an opening (47) in the front face (45) for allowing insertion of a plug into the socket (19).

  • Patent number: 5667390
    Abstract: An I/O card and associated cable harness assembly (20) comprises an I/O card section (22) and a cable harness section (60) wherein the cable harness section (60) substantially structurally extends out of the I/O card section (22). The distal end of the cable harness section (60) is connected to an outside environment device (100). The cable harness section (60) has an engagement section (72) adapted to be latchably engaged within a cavity (32) in the I/O card section (22). There are a plurality of independent respective wires (64) extending within and along the cable harness section (60), and the front end of each wire (64) is appropriately solderably mounted to the corresponding pad on the internal PC board (26) in the I/O card section (22). The cable harness section (60) is substantially pre-assembled to the I/O card section (22) before the I/O card section (22) itself has been completely assembled.
