An electrical connection box includes a fusible link including a pair of terminal portions, a plate-shaped conductive member, a first nut including a first flange portion and fastened to the conductive member by being screwed with a first screw member, a second nut including a second flange portion and fastened to the conductive member by being screwed with a second screw member, and a block that includes a holding portion holding the first flange portion and the second flange portion and holds the fusible link. The holding portion extends between the pair of terminal portions in a projecting direction of the terminal portions, and includes a first holding portion located on a back side in an insertion direction, a second holding portion located on an entrance side in the insertion direction, and a projecting portion allowing entry of the first flange portion and restricting entry of the second flange portion.

A fuse assembly includes a casing having two slots defined through the first end thereof, and a conductive member is located in the casing and has a first end extending through the second end of the casing. The conductive member includes two blades with a fuse connected therebetween. A cap is detachably mounted to the first end of the casing and has a light member connected thereto. The light member has a leg portion which is electrically connected to a second end of the conductive member. The cap includes two arms which are detachably hooked to two positioning members on two sides of the casing to ensure the connection between the cap and the casing. When the fuse is burned off, the light member lights on, the cap is removed from the casing, and is detachably connected to a new casing with a functional fuse therein.

A method of making printed circuit board vias using a double drilling and plating method is disclosed. A first hole is drilled in a core, the first hole having a first diameter. The first hole is filled and/or plated with an electrically conductive material. A circuit pattern may be formed on one or two conductive layers of the core. A multilayer structure may then be formed including a plurality of cores that also include pre-drilled and plated via holes, wherein at least some of the pre-drilled and plated via holes are aligned with the first hole. A second hole is then drilled within the first hole and the aligned pre-drilled and plated holes, the second hole having a second diameter where the second diameter is smaller than the first diameter. A conductive material is then plated to an inner surface of the second hole.

Fuse assemblies are disclosed. In one implementation, a fuse assembly may be disposed that includes a first portion of the second portion. The first portion may be formed of a first metal. The second portion may be formed of a second metal different from the first metal. The second metal may be copper, and the copper may be tin plated or silver plated.

An embodiment of a fuse module has been disclosed. The fuse module includes a housing and a fuse element assembly contained within the housing. The fuse element assembly includes at least one fuse element unit having a plurality of trigger mechanisms and a perforated strip electrically connected to the trigger mechanisms. Increased ampacity ratings in a more compact arrangement provides for fuse modules having increased current protection capability that, in turn, provides for improved disconnect switching capabilities.
