Power connectors with integrated fuse support, and associated systems and methods are disclosed. A representative power connector can include a power port and a mating plug. The power port can include a fuse support having first and second fuse receptacles, wherein the first fuse receptacle is connectable to a first supply cable. The power port can include first and second port terminals, wherein the first port terminal is connectable to a second supply cable. A jumper cable can be connected between the second port terminal and the second fuse receptacle. The plug can include a housing configured to enclose the fuse support between the plug and the power port when the plug is mated to the power port. The plug can include first and second plug terminals mateable with the first and second port terminals.

A connector includes a housing body, a shield shell that externally covers the housing body, a first connection terminal that is housed in the housing body, electrically connected to a first wire in the housing body, and electrically connected to a counterpart terminal when the connector is connected to a counterpart connector, and a circuit protection component that is interposed, in the housing body, between the first connection terminal and the first wire, and connects the first connection terminal and the first wire in series to protect a circuit. The housing body includes at least one thermal conductor that performs thermal conduction with the circuit protection component by being in contact with the circuit protection component.

An electric connection block is provided with a bus bar formed from a press-formed product of a metal plate member and a resin-made housing insert molded integrally with the bus bar. The bus bar is provided with a flat plate-shaped main plate part and a standing terminal erected by bending a base end connected to a portion of the main plate part relative to the main plate part. The electric connection block is manufactured by insert molding the housing integrally with the bus bar in a before-bending state where the standing terminal is located on the same plane as the main plate part, and bending the base end of the standing terminal to thereby erect the standing terminal relative to the main plate part after the insert molding of the housing.

A plug connection kit for connecting a branch line to a through line, comprising a plug housing and a socket housing that enclose contact inserts. Flexible cable ends are molded onto the plug housing and socket housing. The plug housing and socket housing are each manufactured by casting plastic onto a base body with the contact inserts and flexible cable ends connected thereto inserted, thus forming a solid one-piece plug and a solid one-piece socket. The female and male contact inserts are electrically connectable to one another in a contact area between the plug housing and the socket housing. The plug connection kit also includes a sealing sleeve that encases the plug housing, the socket housing, and the contact area between the two housings in order to protect the plug connection kit from penetration of water and/or dust.

An electrical plug provides protection against electrical surges with a replaceable surge protector cartridge that is readily removable and replaceable along an exterior of the plug. Surge protector circuitry in the cartridge can absorb an electrical surge received at the plug from an electrical mains source, and the electrical plug can maintain electrical continuity from plug prongs to an electrical cord both before and after the surge protector has absorbed an electrical surge.
