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.

The present invention provides a housing, fuse, and fuse box, with which it is possible to differentiate a multi-pole fusible link and prevent misassembly, while holding down costs. This housing is attached to a multi-pole fusible link contained within a containing part of a fuse box, and is provided with misassembly-preventing protrusions which are removable according to the type of multi-pole fusible link, the locations of the misassembly-preventing protrusions protrusions corresponding to the locations of recesses recesses which are provided to the containing part that is to contain the multi-pole fusible link, and in which the misassembly-preventing protrusions can be contained.

A connector configured to be fitted with a mating connector includes a main housing, a sub-housing supported on the main housing to be slidable in a fitting direction with respect to the main housing in which the connector is fitted with the mating connector, and an operating member pivotably and slidably supported on the main housing. The main housing moves closer to the mating connector when the operating member is pivoted from a first posture to a second posture. The sub-housing moves in the fitting direction when the operating member slides from the second posture in a direction different from the fitting direction. The sub-housing has an erroneous fitting prevention part abutting against the mating connector in a state of incomplete fitting of the connector with the mating connector.

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.

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.

An exemplary embodiment of active/passive automotive fuse module in accordance with the present disclosure may include an electrically insulating base, a fuse plate including a bus bar portion disposed on a top surface of the base above a projectile cavity formed in the base, the fuse plate further including a fusible portion electrically connected to the bus bar portion and adapted to open when an amount of current flowing through the fuse plate exceeds a current rating of the active/passive automotive fuse module, the active/passive automotive fuse module further including a pyrotechnic interrupter (PI) disposed atop the base and including a projectile positioned above the bus bar portion, the PI configured to drive the projectile through the bus bar portion upon actuation of the PI.

A method of assembly of an open-cavity, wire-in-air fuse which provides improved manufacturing yield and fuse reliability, involving coiling, braiding or twisting a fusible element around a sacrificial member during the manufacturing process to provide support for the fusible element to prevent mechanical breakages and necking problems commonly encountered during manufacture.

A fuse holder provides a safe device for connecting fuses to a three-phase busbar device. Each phase includes a corresponding load conductor and line conductor mounted within a housing. A mechanical lock is provided for each phase that locks a knife of the fuse to one of the conductors for the phase. In a further aspect, the fuse knives are frictionally locked within the housing. In both the mechanical lock and frictional lock, a release mechanism is provided that can be activated by a screwdriver to release the fuse knives from the fuse holder. In another aspect, certain conductors are provided with heat dissipation wings that contact the housing to dissipate heat generated by current flowing through the conductor.

Disclosed are various protection devices and associated methods. In some embodiments, a protection device may include a fuse assembly having a fusible link extending between a first lead end and a second lead end, and a first lead extending from the first lead end and a second lead extending from the second lead end. The protection device may further include a body including a first section coupleable with a second section, wherein the first and second sections define a central cavity housing the fusible link. The first section may include an interior face operable to engage an opposite interior face of the second section, an engagement member extending away from the interior face towards the second section, and an engagement channel adjacent the engagement member, the engagement channel operable to receive a corresponding engagement member of the second section.
