There is described an actuator for a damper comprising an electrical circuit, a cable coupled to the electrical circuit, a lower housing supporting the electrical circuit, and an upper housing coupled to the lower housing. The electrical circuit controls positions of the damper. The cable provides power and control to the electrical circuit. The lower housing includes a first trough and a second trough to provide support for the cable in a first direction. The upper housing includes a first protuberance and a second protuberance to provide support for the cable in a second direction. The first and second protuberances are positioned offset from the first and second troughs of the lower housing.

Actuator for a damper and method thereof

There is described an actuator device comprising a single molded housing, a linear bridge feature, a spring hook retention feature, and a power spring. The single molded housing is formed by integrating the linear bridge feature across the single molded housing and the spring hook retention feature to one side of the linear bridge feature. The power spring is inserted laterally through the linear bridge feature of the actuator device. The power spring includes a spring hook at one end, and the spring hook of the power spring attaches to the spring hook retention feature of the actuator device. The power spring applies, at least in part, a torque to a control shaft coupled to the actuator device.

Actuator device having power spring retention

Systems and methods are provided for attaching flexible conduit to an adapter. A pin is inserted opposite a retention rib molded into an aperture of the adapter. Due to the geometry of the flexible conduit and the location of the pin and the retention rib, once inserted, the pin secures the flexible conduit and prevents the flexible conduit from coming loose.

Pin-based non-metallic fittings for attachment of flexible metallic conduit

Systems and methods are provided for attaching flexible conduit to a fitting. Prongs of a conduit retention clip contact opposite sides of the flexible conduit in an aperture of the fitting. By aligning the prongs in grooves of the flexible conduit, the flexible conduit is held in place in the aperture of the fitting without sufficient compression to surpass the structural limits of the fitting.
