A travel adapter and accompanying extension cord are disclosed. The travel adapter and extension cord are designed to work in conjunction with swappable mating adapter plugs. The travel adapter enables compact and convenient storage using an advantageous interlocking design that also protects the travel adapter during transport.

An electrical connector body is provided includes first and second housing portions formed from molded plastic. The housing portions include first and second interface surfaces that are configured to butt against one another to define a housing and one or more electrical components are disposed within an interior of the housing. The one or more electrical components may comprise connectors of a male or female cord cap, an in-line surge suppression circuit, and/or a compact automatic transfer switch. In one implementation, each of the first and second connector body portions may include a strain relief extension for engaging an electrical cord and a compression member (3691) may be disposed over the strain relief extensions to secure together the first and second connector body portions. The compression member may be selected from a set of compression members based on a size of the electrical cord.

A self-locking extension cord for extending electrical power to an associated auxiliary electrical cord includes a power cord having opposed first and second ends, the cord constructed of an elongate adjustable metal material containing a plurality of conductive wires. The extension cord includes male and female electrical receptacles fixedly attached to first and second ends of the cord member. The extension cord includes a male plug receiving member selectively and releasably coupled to the first end of the cord member, the male plug receiving member including first and second pivotally connected receiving portions movable between a closed configuration in which the first and second receiving portions receive one of the male electrical receptacle or the auxiliary male electrical receptacle associated with the auxiliary extension cord. A female plug receiving member is coupled to female electrical receptacle, the male and female receiving members having locking structures for being locked together.

A cable fixture including a first pressing member that includes a first plate portion facing a first outlet and a first connector of a first cable plugged into the first outlet, and a second plate portion bent from the first plate portion to one side in a facing direction between the first plate portion and the first outlet; and a supporting member configured to support the first pressing member and capable of fixing the second plate portion at a position where the first plate portion abuts on the first connector.

The present disclosure provides a locking electrical connector for electrical connection with an outlet connector. The adapter outlet connector includes a first housing, the locking electrical connector includes a second housing, an actuating assembly, and a locking member. At least one electrical connection point enclosing in the second housing, which can be electrically connected to the outlet connector. The locking member is rotatably fixed to the second housing and capable of being driven by the actuating assembly, so as to rotate relative to the second housing, such that the locking member is frictionally locked with the side surface of the first housing, thereby enabling the locking electrical connector to be electrically locked with the outlet connector. The present disclosure can better prevent the electrical connection from failing and loosening.

Retention components are provided that are configured to retain a first end of an electrical cord in a plugged configuration with an electrical outlet. The retention components have an interior sized to receive the first end therein and include an wire opening having at least one dimension that is smaller than the corresponding dimension of the first end so that the first end cannot pass therethrough. In one form, a wall plate is provided having retention portion configured to retain a first end of an electrical cord, such that with the wall plate secured to a wall or other substrate, the first end of the electrical cord is retained between the wall and the wall plate.

An apparatus for locking electrical connectors together and for protecting such electrical connectors. A method of locking electrical connectors together.

A casing for connecting first and second power cords, the casing having a set of grip mechanisms with facing grip members that have serrated surfaces arranged to grip the first power cord and provide increased grip pressure in response to tension applied to the first power cord in order to resist the first power cord being pulled through the grip members and out of the casing.

A retention assembly is provided that is configured to retain a plug end of an electrical cord in electrical engagement with an accessory outlet. The retention assembly includes a housing have an interior sized to receive the plug end and, optionally, an adapter therein. In one version, the housing can include a front opening with an assembly portion and a retention portion where the retention portion has at least one dimension that is smaller than the corresponding dimension of the plug end so that the plug end cannot pass therethrough. In another version, the retention assembly includes an insert having a slot opening to receive the wire portion of the electrical cord therethrough. The insert can then be disposed within the housing such that a sidewall of the insert extends between a front wall of the housing and the adapter to restrict movement of the first end and the adapter.

A method and apparatus (utility) for securing an electrical connection formed by a mating structure including prongs of a male assembly and receptacles of a female assembly are provided. The utility includes a clamping mechanism whereby the very forces that would otherwise tend to pull the connection apart serve to actuate the clamping mechanism, thereby securing the mated pair. The apparatus may be integrated into a standard receptacle, or retrofitted to work with existing devices. In one embodiment, the clamping mechanism acts solely on the ground prong of a standard plug assembly, so that it is unnecessary to consider electrical potentials applied to the clamped prong in relation to the design of the clamping mechanism. Further, the withdrawing movement of the prongs of a plug may cause elongate clamping surfaces of the clamping mechanism to frictionally engage opposing surfaces of the clamped prong.
