Provided is an electrical connection box that is equipped with a newly constructed dark current circuit connection/disconnection mechanism that can be used to change circuits of the dark current circuit connection/disconnection mechanism and improve versatility. A conduction member holder has a conduction member holding portion that extends spanning over a plurality of cavities that are provided in a case. A conduction member includes: a first conduction member that is connected to a connection terminal of a dark current circuit housed in one of the cavities; and a second conduction member that is connected simultaneously to the connection terminal of the dark current circuits housed in one of the cavities and a connection terminal of another circuit housed in another cavity. The first conduction member or the second conduction member that is selected according to a required circuit configuration is mounted in the conduction member holding portion.

An electrical connection box includes a fusible link including a pair of terminal portions, a plate-shaped conductive member, a first nut including a first flange portion and fastened to the conductive member by being screwed with a first screw member, a second nut including a second flange portion and fastened to the conductive member by being screwed with a second screw member, and a block that includes a holding portion holding the first flange portion and the second flange portion and holds the fusible link. The holding portion extends between the pair of terminal portions in a projecting direction of the terminal portions, and includes a first holding portion located on a back side in an insertion direction, a second holding portion located on an entrance side in the insertion direction, and a projecting portion allowing entry of the first flange portion and restricting entry of the second flange portion.

A self-powered wireless fuse switch is disclosed that is a plug-in replacement for a fuse found in the electrical system of vehicles. The self-powered wireless fuse adds remote-controlled switching capabilities for short and long-range control of power to subsystems of a vehicle electrical system. The wireless fuse switch includes a wireless control module having an internal power supply and an internal transceiver that receives commands from a remote control unit. A separate fuse module includes an outer housing and fuse blades that extend from the outer housing and interface with a fuse socket of the vehicle to selectively allow or interrupt power from the vehicle to the subsystem of the vehicle electrical system. The fuse module includes a fusible link, a relay controller and a relay in the outer housing. The fuse module receives power from and communicates with the wireless control module.

A multi-load fuse block, which receives insertion of at least two safety fuses therein, includes: a housing, a first surface of the housing configured with a first fuse slot and at least one second fuse slot; a conductive joint, configured on a second surface of the housing, and in electric connection with the first fuse slot; a first load conductive wire, configured on a third surface of the housing; and a second load conductive wire, configured on a fourth surface of the housing, where the first fuse slot and second fuse slot allow a plurality of safety fuses to be inserted therein or separated therefrom. The first load conductive wires and second load conductive wires of the housing can provide electric connection for automotive electronics, allowing the safety fuses to be in electric connection with more automotive electronics so as to protect them from overcurrent.
