plug and socket assembly

摘要

The assembly has a card and an electric base that are adapted to collaborate with respect to each other in a removable manner. The card comprises two electric tracks (11, 12) that are allowed to collaborate with electric contacts (21, 22) of the base. A magnetic control unit i.e. ring magnet (13), is arranged for displacement of the electric contacts from one position to another position. An unlocking unit is arranged to reduce power ratio between the control force and another control force at the time of separation of the card.
