A connector and a wireless controller for a wired lighting system are disclosed. The connector and wireless controller and connected via two wires. The connector also has at least one cap that covers two channels for electrically coupling additional two wires—one wire for connecting to a power supply and another wire for connecting to one or more lighting devices. The connector can be easily installed in an existing wired lighting system to retrofit the system with a wireless controller.

A spring-loaded terminal contact (3) for contacting electrical conductors having at least one busbar (7) and having at least one clamping spring (9) which has an abutment member (10), a clamping member (12) and a curved resilient member (11) which is arranged between the abutment member (10) and the clamping member (12) is described. The clamping member (12) extends in the direction toward the busbar (7) and has a resilient clamping edge (8) for clamping an electrical conductor which is introduced between the clamping member (12) and the busbar (7) in a conductor insertion direction (L). The busbar (7) has a clamping edge (6) which together with the resilient clamping edge (8) forms a clamping location for the electrical conductor which is intended to be clamped. The busbar (7) has a groove-like recess (14) in the conductor insertion direction (L) upstream of the clamping location adjacent to the clamping edge (6).

A terminal block includes an insulating casing defining a recess receiving a conductive bar and a retaining spring. The conductive bar includes a base portion, a support leg attached to the base portion and a cooperating leg attached to the base portion. In a mounted position of the conductive bar and the retaining spring within the recess, the support leg engages with a support part of the retaining spring, and the cooperating leg is positioned to engage with a conductor inserted into a plug of the terminal block.

A module connector for electrically connecting a pair of electric modules includes a pair of contact assemblies spaced from one another and fastening the module connector to the electric modules, a conductor assembly electrically connecting the contact assemblies and, with the contact assemblies, forming an electrical connection between the electric modules, and a housing formed of an electrically insulating material. The contact assemblies and the conductor assembly are accommodated in the housing. At least one of the contact assemblies is fastened to the conductor assembly in a manner displaceable relative to the conductor assembly in a direction of displacement directed towards and/or away from the other of the contact assemblies.
