A power distributor including a first conductive coupling device electrically coupled to a bare-wire non-terminating section of a first conduit. A second conductive coupling device is electrically coupled to a terminating end of a second conduit. The first conduit is a larger gauge than the second conduit. A fuse electrically connects the first conductive coupling device and the second conductive coupling device. A housing encases the first and second conductive coupling devices and the fuse.

A branch box (100) includes: a branch portion (21) branching a power path (205A) into at least two branch paths (206A, 207A); a fuse (60) located on at least one of the branch paths; a conductive member (33) connecting the branch portion and the branch path having the fuse; a first housing portion (11) receiving the fuse and closing its opening with a lid portion (81) to define a housing space; and a second housing portion (12) receiving the branch portion. The first housing portion is sealed with a first sealing material (85) filling a gap between the lid portion and the opening and is out of contact with the fuse. The second housing portion is sealed with a second sealing material (86) independent from the first sealing material. The conductive member passes through a partition wall (25) separating the first housing portion and the second housing portion.

A rotary connector device includes a fixed body, a rotation body, and an inhibiting structure. The fixed body includes a first fixed body portion and a second fixed body portion disposed facing each other with a space being defined between the first fixed body portion and the second fixed body portion. The first fixed body portion and the second fixed body portion are coupled at a coupling portion. The rotation body rotatably is assembled to the fixed body. The inhibiting structure is configured to inhibit foreign matter from entering the space through the coupling portion. The coupling portion is exposed to an outer surface of the fixed body.

A battery maintenance system for use in performing battery maintenance on a battery of an electric vehicle including a battery maintenance device and a high voltage connector configured to connect the battery maintenance device to the battery of the electric vehicle. When a fuse door is removed from a fuse block of the connector, a mechanical component in a first position blocks a keying post and prevents a first connector side from coupling with a second connector side of the connector When the fuse door is in place and covering an interior of the fuse block, the fuse door places the mechanical component into a second position to allow the keying post to mate with the second connector side and to activate an electric switch to connect voltages to the fuse block.

In one embodiment of the present invention, there is described a surge immune terminal block assembly consisting of a terminal block comprised of a base housing unit and a surge protection housing unit, such that when the base housing unit and the surge protection housing unit are coupled together, the terminal block provides electrical connectivity and surge protection. Extruding from the body of the surge protection housing unit are polarity protected mechanical plugs that dock into corresponding cut-away portions in the base housing unit. When docked, the mechanical plugs connect with electrical terminations to provide an electrical connection between the electrical connectivity components of the base housing unit and the surge protection components.
