A fuse assembly includes a fuse element, a first terminal, a second terminal, a socket, and a capsule. The fuse element is disposed between first and second end bells. The first terminal includes a first bell portion, a first socket portion, and a first capsule portion, the first bell portion being connected to the first end bell. The second terminal includes a second bell portion, a second socket portion, and a second capsule portion, the second bell portion being connected to the second end bell. The first socket portion and the second socket portion are integrated through the socket. The first capsule portion and the second capsule portion are integrated through the capsule. The socket is seated atop the capsule to create an interior chamber inside which the fuse element is disposed.

A vertically-oriented blade fuse system requires less surface area on a printed circuit board, provides improved heat dissipation, is less expensive to manufacture and assemble and is more reliable. It comprises a fuse having two connection plates that extend away from each other in opposite directions. One of the plates is forced into a fork-shaped connector, which grabs both sides of the plate. The other connection plate is fit into a mating female connector. Multiple vertically-oriented fuses, laterally spaced from each, are connected to corresponding connection forks and female connectors inside a housing, which can be latched to a circuit board.

Provided are approaches for modularized power distribution. In one approach, an apparatus may include a module extending into an interior cavity of a housing assembly through an opening formed in a base section of the housing assembly. The module may include a component grid at one end for receiving one or more components (e.g., fuses, relays, circuit breakers, diodes, etc.), and a wiring alignment cover at an opposite end operable with a terminal. The apparatus may further include a mechanical sealing element disposed along one or more surfaces of the module to provide a seal between the module and the base section defining the opening. In another approach, a plurality of modules may be disposed within a plurality of openings formed in the base section. In another approach, the apparatus may include a bracket configured to releasably connect the base section and the cover.

A printed board with board terminal having a novel structure, capable of lowering the support position of an electrical component supported on a printed board and enabling electrical components to be mounted on both sides of the printed board while reducing height, and an electrical connection box using the same is provided. The printed board 34 includes through holes 62 through which tab terminals 76 are inserted. A board terminal 32 includes an insertion hole 38 into which the tab terminal 76 is inserted and a connecting portion 42 projecting inwardly of the insertion hole 38 is pressed into contact with the tab terminal 76. A tab terminal inserting portion 72 is formed by arranging the through hole 62 and the insertion hole 38 such that the through hole 62 and the insertion hole 38 overlap each other in a plan view.

A fuse holder comprises first and second body halves. The first body half includes a wall having a fuse cavity, a first channel extending from a first end of the fuse cavity of the first body half, and a second channel extending from a second end of the fuse cavity of the first body half. The second body half includes a wall having a fuse cavity, a third channel extending from a first end of the fuse cavity of the second body half, and a fourth channel extending from a second end of the fuse cavity of the second body half. The first channel and the third channel mate together and form a first fuse lead guide path, and the second channel and the fourth channel mate together and form a second fuse lead guide path.

A second body half comprises a wall having a fuse cavity formed therein, a third channel formed therein and extending from a first end of the fuse cavity of the second body half, and a fourth channel formed therein and extending from a second end of the fuse cavity of the second body half. The first channel and the third channel mate together and form a first fuse lead guide path, and the second channel and the fourth channel mate together and form a second fuse lead guide path.

An electrical module, a backplane for the electrical module, and a method of replacing a fuse for the electrical module. The electrical module includes a circuit board which has a power input port for inputting electric power to electrically drive an external device coupled to the electrical module. The electrical module also includes a fuse holder electrically coupled to the power input port and adapted to receive a fuse. A fuse detecting circuit is arranged on the circuit board and electrically coupled to the fuse via the fuse holder to detect a status of the fuse. An output port is arranged on the circuit board and coupled to the fuse detecting circuit to at least output detecting signals about the status of the fuse to a controller.

An integrated field output terminal assembly for traffic controller cabinets includes a circuit board carrying high-density flash-transfer relays and output terminals on a front side, and a short-circuit protection subassembly on a rear side. The protection subassembly has rows of plug-in fuse holders electrically connected through the board to incoming power channels from high-density switch packs, with surge suppressors located between fuse sections. An insulating panel, spaced by standoffs, shields the rear circuitry while providing labeled openings for rapid fuse access. A swing-down mounting bracket lets the board pivot within the cabinet for tool-less inspection and replacement of fuses. By placing circuit protection on the same footprint as the output board, the assembly eliminates separate fuse panels and bulky harnesses, cutting cabinet volume, material cost, and service time while safeguarding switch packs against shorts, lightning, and wiring faults.
