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.

A rotatable receptacle and method of assembling and mounting a rotatable receptacle. The receptacle includes an outer ring that has a mounting surface for mounting to a housing, and a rotatable insert that is received in the outer ring. An inner surface of the outer ring surrounds an outer surface of the rotatable insert. The rotatable insert has an electrical face configured to mate with a photoelectric device and an opposite mounting face for mounting to the housing. The rotatable insert is rotatable with respect to the outer ring to orient the rotatable insert in a desired direction for optimal positioning of the photoelectric device. The outer ring and the rotatable insert have corresponding interlocking features configured to fix the rotatable insert in the desired direction.

An expansion device includes a supporting base and a hub. The supporting base includes a bottom portion, a supporting portion, and an electrical connection port. The supporting portion is connected to the bottom portion and has an insert slot. The electrical connection port is disposed at the bottom portion. The hub is slidably disposed within the supporting portion and is located between the bottom portion and the insert slot. The hub includes a first electrical connection element and a second electrical connection element facing away from the first electrical connection element. The first electrical connection element is electrically connected to the electrical connection port, and the second electrical connection element extends into the insert slot. Another expansion device is also provided.

A relay socket providing an interface between a relay and a mounting structure comprises an upper section configured for mounting the relay, a lower section configured for mounting to the mounting structure, a plurality of mounting holes opening to an upper surface of the upper section and configured to receive a plurality of fastening elements of the relay, and a plurality of sleeve inserts configured to be fastened within the mounting holes, Each of the sleeve inserts surrounds a fixation member adapted to connect to the fastening elements.

The inspection socket includes: a contact terminal 80 including a barrel 82 having a flange section 90, a device-side terminal 84, and a board-side terminal 86; housings 10, 30, and 50 having through holes 10c, 30c, and 50c into which the contact terminal 80 is inserted; and housings 20 and 40 having through holes 20c and 40c into which the contact terminal 80 is inserted, the through holes 20c and 40c being larger than the outer diameter of the contact terminal 80 excluding the flange section 90 and smaller than the outer diameter of the flange section 90. The housings 20 and 40 are sandwiched between the housings 10, 30, and 50, the flange section 90 is contained in the through hole 50c, and the through holes 10c, 30c, and 50c are designed to have, for impedance matching, a gap from the outer periphery of the contact terminal 80.

The present disclosure discloses a lamp socket connector, a lighting device and a lighting system. The lamp socket connector includes a docking portion. The docking portion includes a docking port for docking a light source module, a docking channel extending from the docking port, and at least two socket terminals in the docking channel.

An IC socket incudes a socket body having a housing portion for accommodating an IC package; a contact pin electrically connected to a solder ball of the IC package; an operating member provided movably up and down on the socket body; and a pad which is opened and closed by an up and down movement of the operating member and covers an upper side of the IC package in a closed state.
