Abstract
A load bearing housing provides environmental protection and submergibility to an actuator and associated control electronics housed within, and effectively carries the resultant stresses and moments produced by the actuator when actuated. The housing comprises a plastic enclosure which generally seals the actuator and control electronics within an internal cavity. A metal bracket supports the actuator within the enclosure. The enclosure is connected to a rigid, metal strong back which reinforces the bottom and lower sides of the enclosure. The bracket also attaches to the strong back such that when the actuator is actuated, the bracket and strong back carry the resultant stresses and moments. The plastic enclosure is substantially isolated from such stresses, and, thus, is less likely to fracture.
