Junction boxes are disclosed relating to commercial and residential wiring that include a container and multiple push in locking electrical connectors. The push in locking electrical connectors are arranged facing the exterior of the box such that the box is operable without being opened and such that the individual conductors of multiconductor wires may be conveniently wired to separate sets of push in locking electrical connectors electrically joining the multiconductor wires.

A high-power plug connection system has a cable connection housing for connecting at least two electric high-power plug connectors in order to transmit and/or distribute a high current strength and/or a high electric voltage. The cable connection housing receives at least two insulating bodies for receiving at least one respective high-power contact and at least one electrically conductive rail in an interior. The rail is designed to establish an electrically conductive connection between the at least two high-power contacts, and the insulating bodies protrude at least partly out of the interior through a respective housing opening and into a connection region, the connection region being designed to receive the high-power plug connector.

A connection assembly of a connector comprises a connection housing, a locking element and a position assurance device. The connection housing is interconnectable with a counter connection housing along a connection axis. The locking element is movable between a locking position fixing the counter connection housing to the connection housing, and a release position releasing the counter connection housing from the connection housing. The position assurance device movable between a disconnection position, in which the position assurance device permits movement of the locking element from the locking position to the release position, and a blocking position, in which the position assurance device fixes the locking element in the locking position. The position assurance device is rotated about the connection axis on the connection housing when moving between the disconnection position and the blocking position.

Various techniques are provided for displacing air from partial discharge sensitive regions of a connector of a low partial discharge high voltage connector to other regions of the low partial discharge high voltage connector where electrical flux is reduced. A plug member is mated with a receptacle member to provide the connector, with a seal member disposed in a cavity provided by the plug member and/or the receptacle member. In response to the mating, the seal member is compressed at an initial contact region between an innermost layer and an outermost layer of the seal member. In response to the compressing, air is forced radially inward toward the innermost layer and radially outward toward the outermost layer away from the initial contact region to reduce partial discharge associated with the connector. Additional methods and systems are also provided.

A connector system for use in a power distribution system includes a male terminal assembly, a female terminal assembly and an internal spring. The male terminal assembly includes a male terminal body formed with a spring receiver, a base wall, and a plurality of contact arms extending forward from the base wall and arranged along a curvilinear contact arm path. The contact arms are spatially arranged such that a contact arm opening resides between a pair of contact arms in the plurality of contact arms and no intervening structure of the male terminal body resides between a pair of contact arms in the plurality of contact arms. The internal spring is dimensioned to reside within the spring receiver, and includes a plurality of spring arms arranged along a curvilinear spring arm path. The female connector assembly has a female terminal with a female receptacle. An insertion force of less than 45 Newtons is applied on the male terminal assembly to position an extent of it within the female receptacle to arrive at a fully connected state where the connector system enjoys high ampacity to transfer over 500 amps between the male terminal assembly and the female terminal with less than a 55° C. rise over the ambient temperature in which the connector system is operating.

A high-voltage cable plug (1) for installing on an end of a high-voltage cable (20) has an insulating part (14) attached to the end of the high-voltage cable (20). The insulating part is cone-shaped at least in some sections on the outer surface of the insulating part and can electrically tight contact a socket element (2) associated with the high-voltage cable plug (1) when the plug-in connection is established. The high-voltage cable plug (1) has a protective element (40) at or near the end of the high-voltage cable plug facing the socket element (2). The protective element protrudes beyond the end of the high-voltage cable plug (1) facing the socket element (2) in a radial direction, with respect to a longitudinal axis (10) of the high-voltage cable plug (1), to such an extent that the protective element (40) prevents damage to the high-voltage cable plug (1) or to the socket element (2) when the high-voltage cable plug (1) is inserted into and removed from the socket element (2).
