Abstract
A fuseholder socket assembly including a side terminal with preferably a pair of helical knob contact finger-engaging surfaces for initially guiding a knob for movement in both axial and circumferential directions toward a locking position where a pair of J-shaped knob contact fingers can interlock with a socket body side terminal with not more than about one-half turn of the knob. The assembly includes a pair of axially inwardly facing abutment shoulders preferably formed by a pair of rigid channel-forming fixed fingers projecting from the side terminal and against which knob contact fingers are urged by a biasing means when the knob is turned into a final locking position and then released. Good electrical contact is preferably achieved by a pair of body side terminal outwardly axially projecting, radially outwardly deflectable resilient contact arms. Each arm has a radially inwardly projecting contact on the inner side thereof positioned to be engaged with a wiping contact by one of the said knob contact fingers when it is rotated into its locking position.
