Plug adaptable to sockets of different diameters

摘要

The connector includes an internal sleeve (10) surrounded by an external sleeve (12) provided with a contact (14). A rotating mechanism (16) is provided on the internal sleeve to adjust the contact diameter when the two sleeves are rotated relative to each other. The mechanism includes a cam (8) which modifies the external diameter of the contact. A spring (15) pushes a second metal contact (21) against the exterior wall of the internal sleeve. A printed circuit (11) interfaces between the two electrical contacts.
