Abstract
Abstract A mobile socket ( 1 ) comprises a base ( 10 ), a cover ( 20 ), a plurality of contacts ( 30 ) mounted in the base, a rotatable cam actuator ( 40 ) for actuating the cover to slide on the base, a protecting mechanism ( 50 ) and a washer ( 60 ). The protecting mechanism comprises a cover plate ( 51 ) in the cover and a bottom plate ( 52 ) in the base. The cover plate defines an elongated slot ( 512 ). A pair of opposite cam stoppers ( 515 ) extends upwardly from one side of the slot. The cam actuator has a protrusion ( 45 ) abutting against one of the cam stoppers during rotation.
