摘要:
An actuator providing improved torque, control, and reduced motor and actuator size is provided. An actuator according to one example may include a base plate, a stationary ring gear on the base plate, the ring gear having an arc of substantially less than a conventional full circle ring gear, a pivot assembly and a drive shaft. In one example, the ring gear is approximately half a circle. The pivot assembly may be pivotally mounted on the base plate. The pivot assembly may also have a control board, a stepper motor and a drive gear coupled to an output shaft of the stepper motor, the drive gear mounted on the pivot assembly such that the drive gear engages the stationary ring gear. In one example, the stepper motor is coupled to the drive gear via a worm gear, spur gear, and a shaft. In another example, the drive gear is mounted directly on the output shaft of the stepper motor. The actuator also includes a drive shaft having an axis parallel to a pivot of the pivot assembly.

A coaxial cable connector formed via multi-shot injection molding has a body formed by multiple injection molding layers of different injection moldable materials about a central inner contact to form an integral connector body. The connector body is provided with a coaxial dielectric spacer of dielectric polymer surrounding the inner contact; a coaxial inner body of injection molded metal composition surrounding an outer diameter of the dielectric spacer; and an outer body of polymer surrounding the inner body. Interlock features provide axial and/or rotational interlock between the layers of the connector.
