Abstract: An electrical connector system can comprise a first connector and a second connector. The first connector can include a first threaded coupling feature defining a first axis. The first connector can also include a first electrical contact with a first contact surface having an annular configuration centered on the first axis by a radius. The second connector can include a second threaded coupling feature defining a second axis. The second connector can also include a second electrical contact with a second contact surface offset from the second axis by the radius. The first and second threaded coupling features can be operable to engage one another to couple the first and second connectors to one another such that the first and second axes are aligned, thereby facilitating contact or separation of the first and second contact surfaces upon relative rotation of the first and second connectors.

Abstract: A lockable relative rotation device can comprise a first body including an outwardly extending inner flange having a first side, and a first interface feature associated with the first side of the inner flange. The lockable relative rotation device can also comprise a second body operable to rotate relative to the first body about an axis and to translate relative to the first body in first and second directions parallel to the axis. The second body can include an inwardly extending outer flange disposed proximate the first side of the inner flange, and a second interface feature associated with the outer flange. The first and second interface features can be operable to selectively engage and disengage one another upon relative translation of the first and second bodies in the first and second directions, respectively.

Abstract: A safety electrical power connector can include a first connector body having a first electrical contact and an outer surface, and a second connector body that engages the first connector body in an axial direction. The second connector body can have a second electrical contact and an inner surface configured to slide relative to the outer surface of the first connector body in the axial direction during engagement of the first and second connector bodies. The outer surface and the inner surface can define a gap therebetween sufficient to establish an isolation enclosure that isolates a volume containing the first and second electrical contacts therein. The gap can be formed prior to electrical communication of the first and second electrical contacts thereby preventing an explosion due to arcing between the first and second electrical contacts.
