Low-current fuse stamping method
A convenient, cost-effective method for manufacturing low-current fuse elements. The method may include the steps of stamping a substrate out of a sheet of material and stamping at least one hole in the substrate. The method may further include the steps of bonding a layer of fuse material to a surface of the substrate with a portion of the fuse material covering the hole, stamping a fuse element out of the portion of fuse material covering the hole, and separating an individual fuse from the fuse material and the substrate. A low-current fuse can thereby be obtained using an easily performed stamping process.

Blade fuse
Disclosed is a highly durable blade fuse for which a fused site in a narrow section and the rated current are determined in conformity with its design and the temperature of which does not increase greatly when a current flows through it. A blade fuse according to the present invention includes terminal sections (A, B) and a connection section (1), which are made of the same metal base material that is zinc or a zinc alloy. Furthermore, a low-melting-point metal piece (3), made of tin, which has an outer size identical or similar to a width of the connection section (1) is melted and stuck on at least one surface of the connection section (1) outside the fused section (2), and is positioned to partially traverse an edge of the fused section (2) or not to traverse the edge but to be adjacent to the edge.
SELF-POWERED WIRELESS FUSE SWITCH
A self-powered wireless fuse switch is disclosed that is a plug-in replacement for a fuse found in the electrical system of vehicles. The self-powered wireless fuse adds remote-controlled switching capabilities for short and long-range control of power to subsystems of a vehicle electrical system. The wireless fuse switch includes a wireless control module having an internal power supply and an internal transceiver that receives commands from a remote control unit. A separate fuse module includes an outer housing and fuse blades that extend from the outer housing and interface with a fuse socket of the vehicle to selectively allow or interrupt power from the vehicle to the subsystem of the vehicle electrical system. The fuse module includes a fusible link, a relay controller and a relay in the outer housing. The fuse module receives power from and communicates with the wireless control module.
Printed board with board terminal and electrical connection box using same
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.
