Multiple fuse device
The present invention provides a multiple fuse device that is compatible with various ratings and reduces an increase in manufacturing cost. A multiple fuse device includes an input terminal, an external terminal, a bus bar that includes a circuit portion disposed between the input terminal and the external terminal, and a housing that covers the bus bar. The external terminal includes an integral external terminal integrated with the circuit portion with a fusible portion interposed between the integral external terminal and the circuit portion, and a fuse-side external terminal that pairs up with a fuse connection terminal connected to the circuit portion. The fuse connection terminal and the fuse-side external terminal provided in a pair hold a fuse exteriorly in a removable manner, the fuse having a fusible portion connected between the fuse connection terminal and the fuse-side external terminal.
ELECTRICAL CONNECTION BOX
The electrical connection box includes a case, a frame that is made of a synthetic resin and whose position is fixed relative to the case, fixed terminals that are fixed to the frame and can be connected to external terminals, a fuse having terminals that are put over the fixed terminals, stud bolts for fastening the external terminals, the fixed terminals, and the terminals of the fuse together, and a holding member that holds the stud bolts. The frame includes an attached portion to which the holding member is attached.
Method of manufacturing electrical connection block
An electric connection block is provided with a bus bar formed from a press-formed product of a metal plate member and a resin-made housing insert molded integrally with the bus bar. The bus bar is provided with a flat plate-shaped main plate part and a standing terminal erected by bending a base end connected to a portion of the main plate part relative to the main plate part. The electric connection block is manufactured by insert molding the housing integrally with the bus bar in a before-bending state where the standing terminal is located on the same plane as the main plate part, and bending the base end of the standing terminal to thereby erect the standing terminal relative to the main plate part after the insert molding of the housing.

MULTIPLE ELEMENT FUSE
Approaches herein provide a multiple element fuse including a first fuse element having a first pair of terminals joined by a first fusible link, and a second fuse element including a second pair of terminals joined by a second fusible link. The first pair of terminals may be directly physically coupled with the second pair of terminals. In some embodiments, the first pair of terminals and the second pair of terminals are stacked relative to one another and joined by one or more linking elements, thus causing the first fusible link and the second fusible link to extend parallel to one another. In some embodiments, a first plurality of terminal pairs are integrally linked adjacent one another along a same plane, and then subsequently coupled to a second plurality of terminal pairs.
Plug-in fuse element
Embodiments disclose a plug-in fuse element comprising a strip-shaped sheet metal part having a first end section, a second end section, and an interposed center section, wherein the first end section is a flat plug-in contact; the second end section is a connecting region configured to connect to a stranded conductor, and the center section is an overcurrent protection device. In some embodiments, a stranded conductor is connected on at least one end to a connecting region of at least one plug-in fuse element. In some embodiments, a wiring system includes at least one stranded conductor connected via a flat plug-in contact of a plug-in fuse element to a flat conductor. In some embodiments, a vehicle comprises the at least one wiring system.
FUSE ASSEMBLY
A fuse assembly includes an insulating block having an upper surface, a lower surface, and a side surface therebetween. The insulating block defines cavities extending therethrough. Each cavity defines a resilient lock arm. A fuse assembly also includes a first terminal stud secured within a first cavity by a first lock arm, a second terminal stud secured within a second cavity by a second lock arm, and a bus bar disposed parallel to the bottom surface of the insulating block. The bus bar is interconnected to the first terminal stud by a lower terminal connected to the bus bar and an upper terminal disposed parallel to the upper surface. The bus bar is interconnected to the second terminal stud by a fusible link having a lower fuse terminal connected to the bus bar and an upper fuse terminal disposed generally parallel to the upper surface.
Mechanical disconnect switch with integrated fuse protection
A circuit protection assembly (CPA) is disposed between a source of power and a circuit to be protected. The CPA comprises a mounting block having a bore extending therethrough and a recess cavity on a first surface of the mounting block. A post having a first end is disposed within the recess cavity and a body portion extends through the bore. The body portion configured to receive a terminal and the second end configured to receive a securing mechanism. A fuse having a centrally disposed aperture is configured to receive the body portion of the post and to receive the terminal for connection to a circuit to be protected. An insulator disposed on the terminal and disposed beneath the securing mechanism. The insulator configured to isolate the post from the terminal and the fuse while allowing the securing mechanism to apply an amount of torque.
