Abstract: Embodiments securely control an electronic asset. In some embodiments, a computer-implemented method of securely controlling an electronic asset includes identifying an asset NFT pertaining to the electronic asset. An ownership status of the electronic asset is computationally evaluated according to a proof of ownership provided by an owner node paired with the electronic asset. Responsive to evaluating the ownership status of the electronic asset, the asset NFT is bound with a representation of an identity of the owner node or of an authorized user node paired with the electronic asset. The bound representation of the identity and the asset NFT are registered on a blockchain associated with the electronic asset. A task is computationally performed involving the electronic asset, and the bound representation of the identity, and the electronic asset is securely controlled, in response to receiving a task request from the owner node or the authorized user node.

Abstract: A power connector having an observation portion includes a housing, a live wire conductive member, a live wire contact plate and a neutral wire conductive member. The live wire contact plate has an elastic force to move away from the live wire conductive member. The live wire conductive member and the live wire contact plate contact with each other by a first limiting element damaged at a temperature of 80°˜299° C., separating the live wire contact plate from the live wire conductive member by that elastic force. The housing includes a transparent observation portion, allowing a user to see through partial or whole part of the first limiting element, of the live wire conductive member and of the live wire contact plate, enabling the observation of whether the live wire conductive member and the live wire contact plate are limited by the first limiting element to remain contacted.

Abstract: A socket protective cover capable of preventing single-opening insertions includes a housing, a sliding base and covers. The housing has insertion openings. The sliding base is capable of transverse displacement in the housing, and has restoring elasticity. The covers are also provided with restoring elasticity, and have blocking members for extending into the insertion openings of the housing. When the blocking members at the covers are not simultaneously pushed and departed from the insertion openings, the other blocking member not pushed away from the insertion opening remains in the insertion opening and blocks sideward movements of the sliding base, thereby forbidding an alien object from pushing away the blocking members and thus preventing the alien object from entering the socket.

Abstract: A multiple socket having rotatable socket units includes pivotally rotatable socket units at a housing. The housing has first and second conducting straps at an interior thereof. The first and second conducting straps are pivotally connected with first and second insertion straps in each socket unit. The socket unit is capable of driving the first and second insertion straps for further freely rotating relative to the housing. Using the above structure, the socket units are capable of adjusting directions thereof, thereby avoiding plugs from blocking insertion openings of adjacent socket units.

Abstract: A rolling press member for power switch includes a metal roller capable of free rolling movements and disposed at an end portion of the press member, with the roller pressing against an internal contact plate.

Abstract: A multiple socket having rotatable receptacles includes a plurality of sets of receptacles at a housing of the multiple socket, and a first conducting strap and a second conducting strap at an interior of the housing. At positions corresponding to positions of the receptacles, the first conducting strap and the second conducting strap are provided with clamping portions for inserting with pins of plugs. At least one set of receptacles is disposed at the housing in a rotatable manner, and the receptacles are provided with insertion openings at positions corresponding to the clamping portions. When the receptacles rotate pivotally, the insertion openings are rotated regard the clamping portions as rotation axes thereof, such that regardless of directions of the receptacles pivotally rotated, the pins of the plugs are penetrated in these specific directions through the insertion openings to come into contact with the clamping portions.

Abstract: A safety socket protective cover includes an outer housing, an inner housing, a sliding cover, an elastic support member and an elastic member. The sliding cover, the elastic support member and the elastic member are disposed at a gap between the outer housing and the inner housing. The sliding cover is provided with wedge members for corresponding with receptacles at the outer housing, wherein each wedge member has a passive inclined plane. The elastic support member has elastic restoring forces and is disposed below the sliding cover. The elastic member is pressed between the sliding cover and the outer housing. When the sliding cover receives abnormal forces, the wedge members block the receptacles at the outer housing due to unequal forces received, thereby preventing alien objects from entering the receptacles.
