A connector for a strip of linear lighting includes an outer shell or block and an adapter configured to be removably inserted into a cavity of the outer shell. The adapter may be a printed circuit board (PCB) adapted to mount wires on one side or edge. On the opposite side or edge, a series of contact pins are formed on the underside of the adapter. The outer shell includes a pressure-applying mechanism, like screws that insert through its thickness and are secured in a bar with threaded holes. The adapter is positioned such that the screws bear on and supply pressure to the contact pins. A strip of linear lighting is inserted into a slot beneath the adapter such that the contact pins of the adapter coincide with the solder pads or other electrical contacts of the strip of linear lighting.

An electrical contact element having a frame clamp comprises a frame with a stationary thread, a clamping shoe and a clamping screw engaging in the stationary thread and being supported on the clamping shoe. A plastic holder with a cavity having two insertion openings arranged on opposite walls of the cavity is provided for inserting two electrical conductors to be contacted with one another, in which the frame clamp is arranged. The frame clamp is captively fixed in the cavity of the plastic holder by means of a latching. The frame clamp is mounted in a floating manner in the cavity of the plastic holder in the direction of at least one axis, which is oriented orthogonally to an insertion direction of the electrical contacts into the insertion openings.

A supply charging device for a mobile device includes a supply power connector having a supply housing having a mating end at the front mated with a receive power connector of the mobile device along a mating axis. The supply power connector has a cable end at the bottom. A supply contact chamber is at the mating end and a supply cable chamber is at the cable end. The supply power connector includes supply power contacts and a data communication module at the mating end. The supply charging device includes a cable assembly extending from the cable end at the bottom of the supply housing. The supply power cables extend along cable axes oriented non-parallel to the mating axis.
