A fuse holder includes a movable tab, a base, and a cover. A stud is affixed to the movable tab and secures a terminal of a bolt-down fuse. A second stud is affixed to the base and secures a second terminal of the bolt-down fuse. The base has a channel into which the movable tab is slidably inserted. The cover connects to the base and is located over the stud and the second stud.

The present invention provides a fuse unit, which reduces the number of components of a bus bar and eliminates alignment of tuning fork terminals, and a method of manufacturing the fuse unit. Disclosed is a method of manufacturing a fuse unit, which includes a bus bar including a battery terminal, a fuse connection terminal, and an external connection terminal and is manufactured by integrating the bus bar and a resin covering body by insert molding. In this manufacturing method, the fuse connection terminal is constituted of an input side tuning fork terminal connected to the battery terminal and an output side tuning fork terminal connected to the external connection terminal, the input side tuning fork terminal and the output side tuning fork terminal are connected by a joining portion so as to face each other, the bus bar including the fuse connection terminal is integrated with the resin covering body by insert molding. After the insert molding, the joining portion is cut and removed through a cutting window of the resin covering body, which exposes the joining portion to the outside, and the input side tuning fork terminal and the output side tuning fork terminal are separated.

A fuse holder includes a holder base comprising a plurality of protrusions each having a mounting hole formed therein to provide for mounting of the holder base to an external component and one or more mating protrusions and one or more mating slots formed on each of opposing side surfaces. The fuse holder also includes an input stud coupled to or formed on the holder base and a cover configured to attach to the holder base to at least partially enclose one or more fuses positionable on the fuse holder. The one or more mating protrusions and the one or more mating slots formed on each of the opposing side surfaces of the holder base comprise dovetailed protrusions and slots of a matching profile capable of receiving such a dovetailed protrusion, so as to enable a side-by-side stacking and interlocking of fuse holders with such mating protrusions and mating slots.

A circuit device for a vehicle is arranged in a power supply path. In the circuit device, a first conductive pattern and a second conductive pattern are arranged on an insulating layer. The first conductive pattern and the second conductive pattern are connected to each other by a fuse (circuit element). A bus bar is arranged on the first conductive pattern. Therefore, when a current flows through a conductor constituted by the bus bar and the first conductive pattern, the amount of heat generated in the conductor is small.

Apparatus for enabling distribution of electric power, fusing, and/or ground connection in electrical systems is provided. The apparatus may include an extensible, interlocking, modular block of multiple-use modules. Each module may be configured to include a fuse or a link bar mounted within it. Each module may accept multiple sizes and types of fuses. Each module may be configured to include an external link bar for providing an electrical connection to at least one other module. Apparatus may enable distribution of electrical power, fused power, and/or ground connection from a power source to a plurality of electrical components while organizing and minimizing wired connections.

Provided herein are modular fuse holders for single bolt fuses. In some approaches, a fuse holder may include a base having a lower wall and a set of sidewalls, the lower wall including a plurality of bolt openings provided therethrough. The fuse holder may further include a cover securable with the base, the cover including an upper wall and a set of outer walls, the outer walls including a plurality of cable openings, wherein the base and the cover define an interior cavity for housing a bolt assembly. In some approaches, the fuse holder may include a busbar atop the lower wall of the base, the busbar including a set of openings aligned with one or more of the bolt openings of the lower wall. In some embodiments, a side cover may extend over some of the plurality of cable openings in the outer wall of the cover.

A reduced height relay block for use within a power distribution device for a vehicle electrical system. In one embodiment, there is provided a power distribution device that routes or distributes power throughout a vehicle electrical system and includes a lower housing, a relay block assembly, a module with a printed circuit board (PCB), an array of serviceable electrical components, and an upper cover. The relay block assembly includes a relay block with an upper side that is generally planar and includes a number of cavities for receiving the serviceable electrical components. An underside of the upper cover includes clearance ribs specifically designed to oppose certain serviceable electrical components and prevent them from backing out of their respective cavities.

A distribution block element having opposed input and output couplings and integral complimentary mechanical connectors to additional adjacent distribution block elements, allowing expansion by addition of distribution block elements. Fuse couplings are spaced apart for a mini2 blade fuse and have a length that is are spaced apart for a maxi APX heavy duty fuse and for direct conductors. When two elements are connected adjacently, the spacing between the adjacent crossbar couplings is the same as the spacing between the opposed input and output fuse couplings in each element. Thus, identical crossbar conductors can be used both for electrically connecting opposed input and output couplings and for electrically connecting input couplings of adjacent elements.
