A modular lighting system adapted to be installed in and illuminate an environment. The lighting system includes a first light fixture including a first canopy assembly adapted to engage a desired surface in the environment, a first light-emitting diode (LED) module, and a second LED module. The first LED module has a first connector assembly configured to mechanically and electrically connect the first LED module to the first light fixture via the first canopy assembly, the second connector assembly is configured to mechanically and electrically connect the second LED module to the first LED module, and the first LED module is interchangeable with a third LED module including a third connector assembly configured to mechanically and electrically connect the third LED module to both the second LED module and the first light fixture via the first canopy assembly.

A connector includes a housing configured to accommodate a connection terminal, a shutter that is rotatably provided in the housing and is configured to open and close a front opening of the housing, a rotation arm that is rotatably supported to the housing about a rotation axis and has an arm portion and a connection engagement portion, and a connection member that is provided so as to be rotatable together with the shutter and includes a first lever portion that is pressed and rotated by a tip end of the connection engagement portion. A pressing force of the mating connector acts on the arm portion so as to rotate the rotation arm, and thus the shutter is rotated together with the connection member rotated by the connection engagement portion so as to open the front opening.

The present disclosure relates to the technical field of data cables, more particularly to a unidirectional free-pulling data cable that includes a first wire, a second wire and a hollow housing in which a wheel core, a follow-up circuit board, a clamping assembly, and a fixed conductive board disposed on one side of the housing corresponding to and electrically connected to the follow-up circuit board are arranged. The wheel core, with an elastic member disposed therein and a wheel cover disposed at the opposite side thereof, rotates relative to the housing. The first and second wires are exposed out of the housing partially. The clamping assembly cooperates with the wheel cover to position the wheel core to limit the rotation thereof, which solves the problem that the input and output ends of the existing telescopic data cable need to be stretched simultaneously when using, and is more convenient to use.

A connection device includes two adjacent connectors, a first connecting portion, and a second connecting portion. The two adjacent connectors are configured to support a flexible member. The first connecting portion of a first connector of the two adjacent connectors is rotatably connected to the second connecting portion of a second connector of the two adjacent connectors. The first connector rotates relative to the second connector based on relative rotation between the first connecting portion and the second connecting portion. The two adjacent connectors rotate to a first limit position and a second limit position based the relative rotations between the first connector and the second connector.
