Disclosed is a fast self-adaptive rotary plug-in underwater force-bearing connector, which comprises a plug part and a socket part, wherein the plug part comprises a plug housing, a pin arranged in the plug housing, and a push-pull sleeve, a rotary sleeve, a front retaining ring, a ratchet lock nut and a rear retaining ring arranged outside the plug housing; the socket part comprises a socket housing and a jack arranged in the socket housing; the pin and the jack cooperate to connect the plug part and the socket part. The fast self-adaptive rotary plug-in underwater force-bearing connector of the present application can work under the working condition of a large tensile force and has a high reliability.

A connection assembly including a first connector comprising a post, and a second connector. A body of the second connector comprises a fastening passage. The post can penetrate into said fastening passage by moving in a fastening direction, so as to reach a fastening position. In the fastening position, the post cannot move in a disassembly direction opposite to the fastening direction. The connectors are configured in such a manner that an external action applied solely to the post allows the post to pass from the fastening position to a free position, in which the post can move in translation in the disassembly direction. In fastening position, the post is in a predetermined angular range. The connection assembly further comprises angular returning means to return the post into said predetermined angular range relative to the axis of the post, when the post is fastened to a body of the first connector.

A connector includes two insulators which hold contacts connected to lead wires and are arranged on two surfaces of a base end portion of a ceramic element, two spring components which have flat plate portions located on respective outer surfaces of the two insulators and spring portions supported by the flat plate portions, and a cylindrical sleeve. Each spring portion has an inclined surface which inclines in a movement direction in which the sleeve moves toward the spring components. Each spring portion is elastically deformed by the sleeve hanging over the spring portion. The two insulators hold the base end portion from two sides by being pushed by the flat plate portions in directions in which the two insulators are brought closer to each other. The contacts are pushed against the terminal electrodes.

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 tamper resistant nightlight for placement in an electrical receptacle, the nightlight includes a body that has a base with an LED circuit and plug blades extending from the body. A housing includes a locking element configured to restrict a child from removing the nightlight from the electrical receptacle through a flange that extends away from the body to be positioned behind a rear surface of an electrical wall plate associated with the electrical receptacle to prevent the tamper resistant nightlight from being removed from the electrical receptacle while the electrical wall plate is coupled to the electrical receptacle.

A connecting-fixing structure, used for detachably connecting a main body of an electrical appliance with a power cord, includes a connection end, a locking member, and a rotating sleeve. The locking member includes a supporting shaft and a locking portion which rotates by the supporting shaft as a fulcrum. A locking fitting portion is disposed on the tail end of the power cord and adapted to the locking portion. Furthermore, a rotating sleeve is rotatably sleeved on the connection end, an inner wall of the rotating sleeve has a driving part, and the rotating sleeve rotates to drive the driving part to further drive the locking portion to rotate, thereby locking the locking portion or unlocking the locking portion from the locking fitting portion. The power cord can be disassembled and assembled only by rotating the rotating sleeve, and the operation is convenient, and the structure is simple.

A connecting device includes a plug connector receivable into a receiving space of a mating connector. In a connection position, a latching arm of the plug connector is engaged with a latch receiver of the mating connector. The plug connector has a securing unit for locking and releasing the latching arm. The mating connector has a counterstop element which, when the plug connector is introduced into the receiving space, strikes a deflection chamfer of the securing unit and deflects a securing arm of the securing unit perpendicularly to the direction of insertion and in parallel to a base side of the plug connector so that, in the connection position, a stop surface of the securing unit is arranged at an offset from a stopper element of the securing unit, and the securing unit is movable into a locked position.
