Abstract: The invention relates to a locking element for locking and unlocking a cable connector and a counterpart, said locking element extending along a longitudinal axis between a rear side and a mating side. At the mating side two or more resilient beams extend substantially parallel to the longitudinal axis and contain one or more locking structures including an insertion surface and a locking surface building an angle with the longitudinal axis. The insertion surface and locking surface have an inclined orientation with respect to the longitudinal axis wherein the angle of the locking surface is larger than the angle of the insertion surface but substantially smaller than 90 degrees. The invention further relates to a connector system wherein one or more of these locking elements are applied to connect a cable connector and a board connector.

Abstract: An adaptable plug is intended to be inserted into power supply hole devices. The plug comprises a grip member and an insertion member, wherein the insertion member comprises a first contact means for power connection at the bottom of the hole, and an adaptation member situated in front of the grip member. The adaptation member is provided with at least one electrically conducting adaptation means. The said adaptation means comprises a base and legs, wherein edges between the legs and the base form at least two connection areas, to be brought into contact to the inner wall of the power supply hole device for supplying power to the plug.
