A fuse unit attachment structure includes a fuse bracket to be mounted on a fuse unit directly attachable to a battery and a bracket connecting member for connecting the fuse bracket to the battery. The fuse bracket has a unit supporting portion to support the fuse unit so as to be movable in a direction perpendicular to a lateral surface of the battery and a connecting member engaging portion to be engaged with the bracket connecting member so as to be movable in a direction along the lateral surface of the battery.

A cover for a vehicle electrical system component, such as a pre-fuse assembly, that includes an integrated hinge and locking mechanism. The integrated hinge allows a pivoting cover portion to easily be rotated out of the way in order to give access to an underlying component (e.g., a jump post), while the integrated locking mechanism allows that same cover to be securely locked onto itself when no access is needed. The cover is not limited to a pre-fuse assembly and may be used with other vehicle electrical system components, such as a power distribution device (e.g., a power distribution box, an electrical connection box, a junction box assembly, etc.), a wire harness protector, etc.

An electrical device assembly and method to attach an isolated single stud fuse assembly to an electrical device are disclosed. The electrical device assembly consists of multiple studs, one or more of which is replaced with the isolated single stud fuse. A conductive copper landing zone receives an electrically isolated steel stud. When the landing pad assembly is orbital riveted into a plastic housing of the electrical device, the stud is locked into the housing permanently. Electrical devices such as disconnect switches and power distribution modules, both of which include multiple studs, are good candidates for being adapted with the single stud fuse assembly.

A fusible link includes a power supply portion provided on a connection terminal that connects to a battery terminal, a circuit terminal that connects to a circuit, a power-supply side upstanding portion standing in an out-of-plane direction of a terminal mounting surface from an edge substantially parallel to an extending direction of the battery terminal out of an outer circumferential edge near the power supply portion of the connection terminal, a circuit-side upstanding portion standing in the same direction as the power-supply side upstanding portion from an edge substantially parallel to the extending direction out of an outer circumferential edge of the circuit terminal, and a bridge portion extending between the power-supply side upstanding portion and the circuit-side upstanding portion. The power-supply side upstanding portion, the circuit-side upstanding portion, and the bridge portion function as a fuse element that fuses when a current greater than a threshold value flows.

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 fuse is at least partially located between a first load relay and a first charging relay, and an electric current detector is at least partially located between a second load relay and a second charging relay. The electric current detector is in contact with an insulating layer. As viewed from the side, the fuse is located below the electric current detector. The fuse is not in contact with the electric current detector.

A single bolt fuse assembly and method to connect a single bolt fuse to a circuit or device are disclosed. The single bolt fuse assembly enables the single bolt fuse to be used on any electrical device having a hole suitable for receiving a threaded shaft and connectable to a circuit or device that electrically connects to a female battery or power cable. The apparatus includes a separate high-conductive metal terminal that mates with the stud that mechanically attaches the fuse between the electrical devices. The stud is insulated to avoid becoming part of the electrical circuit and to ensure proper operation of the fuse. By mechanically attaching the stud to the metal terminal, the stud is unlikely to get separated from the fuse.

An electrical connector includes a terminal housing. A first terminal is retained in the terminal housing for movement relative to the terminal housing. A second terminal is also retained in the terminal housing for movement relative to the terminal housing. A flexible bus bar is connected to the first terminal and to the second terminal. The first terminal is able to be moved independently of the second terminal.

A fusible link unit includes a locking member having a first locked portion, a second locked portion, and a pair of first abutted portions; a connection section; a first body having a first locking part and a pair of first abutting parts, the first body being extended from the first boundary in a predetermined direction, and the first boundary being a boundary extending in a direction that intersects a deployed direction of the first abutting parts; and a second body having a second locking part and a pair of second abutting parts, and extending in the same direction as the first body from the second boundary, the second boundary being a boundary extending in a direction that intersects a deployed direction of the second abutting part.

A fuse module including a mounting block formed of an electrically insulating material, the mounting block including a base portion and a wall portion disposed in a perpendicular relationship, the fuse module further including a fuse plate including an electrically conductive bus bar disposed on a bottom of the base portion, a fusible element electrically connected to the bus bar and disposed adjacent a front of the wall portion, and a fuse terminal electrically connected to the fusible element and disposed on a top of the base portion, the fuse module further including an electrically conductive terminal post extending from the top of the base portion and through the fuse terminal for facilitating connection to an electrical component.
