Abstract: Disclosed is a pluggable power supply device. When a pluggable plug is to be in combination with a power supply seat, an insertion portion is first inserted in an accommodation portion of the power supply seat, allowing a second engagement portion to be engaged with a first engagement portion, and causing the gripping device on the power supply seat to be translated horizontally; a sliding block is then moved horizontally to a separation position and drive a first gripping portion on one side of thereof, allowing a second gripping portion to enter the accommodation portion. Thereafter, an elastic element drives the sliding block to translate horizontally to a gripping position, thereby moving the first gripping portion to be engaged with the second gripping portion. When the pluggable plug is to be removed, it can be taken out only by moving the sliding block horizontally.

Abstract: An extractable conversion plug with a safety protection means includes a spring is located between a moveable pillar of a slab and a latching element, inside a connection head, such that the slab can cover conduction pieces through an elastic force from an expansion of the spring, thereby preventing the conduction pieces from being exposed. Upon emplacing the connection head at a base seat, the slab is stopped from moving by a stopper, and the conduction pieces are exposed and are contacted with spring leaves of the base seat, thereby constituting a close-circuit status. When the base seat falls off by accident, a stopping force of the slab is relieved to release a compression force from the spring, which will cause the spring to expand, so as to move the slab to cover the conduction pieces, thereby preventing from getting an electric shock by a careless touch.
