A tap adapter configured to removably couple a coaxial cable connector with a cable tap includes a body, a nut extending about the body, a retaining ring configured to couple the body with the nut, and a collet disposed in the body. The nut includes a first end configured to receive a coaxial cable connector. The collet has a first end configured to receive a center conductor of a cable terminated by the coaxial cable connector and a second end configured to be coupled with a port of a cable tap. The collet is configured to provide an electrical connection between the center conductor and the port of the cable tap. The nut is configured to rotate relative to the body and to slide axially relative to the body as limited by the retaining ring. The tap adapter permits the coaxial cable connector to be removed from the tap adapter while the tap adapter remains mechanically coupled with the cable tap and the second end of the collet remains mechanically and electrically coupled with the port.

A coaxial cable connector assembly including a rear body, a coupler rotatably engaged with the rear body, where the coupler defines an inner channel extending through the coupler between a front portion of the coupler and a rear portion of the coupler, and a nominal portion defining a nominal inner span along the inner channel, and a retainer engaged with the coupler and the rear body, where the retainer couples the coupler to the rear body, where at least one of the retainer and the coupler defines an engagement passage having a non-uniform span, where at least a portion of the engagement passage extends inwardly from the nominal portion of the coupler and is structurally configured to contact an outer conductor of the coaxial cable forming an electrical pathway between the thread of the coupler and the outer conductor of the coaxial cable.

A shielded electrical connector assembly includes an electromagnetic shield integrally formed from a single sheet of conductive material. The shield has a main wall and four side walls surrounding the main wall. The shield defines an opening opposite the main wall having an opening perimeter that is greater than or equal to a main wall perimeter. One of the four side walls defines at least one side wall opening that is configured to receive a shielded wire cable. A method of manufacturing the shielded electrical connector assembly includes the steps of providing a single planar sheet of conductive material, providing a die and a punch, forming the sheet into a cupped shape having a main wall and four side walls surrounding the main wall using the die and the punch, and forming a side wall opening in one of the four side walls.

Systems for optimizing mounting points for coaxial RF connectors, including a printed circuit board (PCB) comprising a coaxial radio frequency (RF) connector; a faceplate comprising an opening adapted to receive the coaxial RF connector; and a bushing positioned within the opening, wherein the coaxial RF connector is positioned within the bushing.

A system to couple a controller to a roadside aerial lighting fixture includes a primary male connector integrated with the controller and a primary female connector integrated with the roadside aerial lighting fixture. The primary male and female connectors are compliant with a roadway area lighting standard promoted by a standards body. The primary male connector protrudes from a first substantially planar surface of the controller. The primary female connector is recessed within a second substantially planar surface of the roadside aerial lighting fixture. A controller-side data connector protrudes from the first substantially planar surface or a third surface substantially parallel to the first substantially planar surface. A fixture-side data connector is recessed within the second substantially planar surface or recessed within a fourth surface substantially parallel to the second substantially planar surface. When the controller is rotatably coupled to the roadside aerial lighting fixture, the primary male connector is electrically coupled to the primary female connector, and the controller-side data connector is communicatively coupled to the fixture-side data connector.
