A fuse module including a mounting block formed of an electrically insulating material, the mounting block having a rear wall extending from a base, a fuse plate including an electrically conductive bus bar disposed adjacent a rear surface of the rear wall, a fusible element electrically connected to the bus bar and disposed adjacent a front surface of the rear wall, and a fuse terminal electrically connected to the fusible element and extending onto a top of the base. The fuse module may further include an electrically conductive terminal post extending from the top of the base through the fuse terminal for facilitating connection to an electrical component.

Provided is an electrical connection box according to which it is possible to easily handle a substrate and a fuse module. An electrical connection box for a vehicle includes: an insertion housing into which a plurality of fuses are to be inserted; a plurality of fuse terminals each having one end portion inserted into a surface of the insertion housing, the fuse terminals connecting the fuses to a substrate; and a holding member that is arranged opposing the one surface of the insertion housing and holds the fuse terminals. The holding member includes a gripping portion provided on a side opposite to the insertion housing, and the gripping portion has a finger placement portion used for gripping.

An attachment structure includes a housing and a plate-shaped cover attached to the housing. The cover has a locking portion to fix the cover to the housing. The housing has a locked portion engaged with the locking portion to regulate a movement of the cover in a direction separating from the housing. The attachment structure is configured to engage the locking portion and the locked portion at an engagement place while the cover and the housing are pressed each other in directions separating from each other at a pressing place distant from the engagement place, and to form a space between the cover and the housing in a region between the pressing place and the engagement place, when the cover is attached to the housing.

A method of assembly of an open-cavity, wire-in-air fuse which provides improved manufacturing yield and fuse reliability, involving coiling, braiding or twisting a fusible element around a sacrificial member during the manufacturing process to provide support for the fusible element to prevent mechanical breakages and necking problems commonly encountered during manufacture.

An on-vehicle device is provided with a fuse. A plurality of terminals each have a long- plate shape and are aligned with each other. A fusible portion is connected to two of the plurality of terminals. A housing covers a part of the plurality of terminals and the fusible portion and has heat resistance equal to or higher than 300 degrees. Current flows through the fusible portion. The fusible portion is blown out in the case where the temperature of the fusible portion exceeds a predetermined temperature.

A straight bus bar includes an axial direction and having a rigid first portion with a first contact surface connectable to a first fuse, an axially spaced rigid second portion with a second contact surface connectable to a second fuse, and a connecting portion electrically connecting the first portion and the second portion. The connecting portion is a resilient compensation portion having at least two lateral recesses extending from opposite sides into the bus bar making the connecting portion elastically bendable to allow a relative axial movement of the first and second portions when an axial force is applied to the bus bar.

A fusible link unit (1) includes a battery (5) with a battery post (3) projecting on an upper surface of the battery (5), a fuse unit (9) arranged on the upper surface of the battery (5) and having a battery terminal (7) connected to the battery post (3), and a fuse cover (11) covering an outer circumference of the fuse unit (9). A deck board (13) is arranged above the fuse cover (11) so as to be capable of being opened and closed. The fuse cover (11) is fixed by being held between the battery (5) and the deck board (13) in a closed state of the deck board (13).

The present invention is a power line cut-out switch used in power transmission system comprising a base member having a vertical extension member perpendicularly attached thereon that secures a mechanical jumper used when transferring power lines from one electrical post to another. The vertical member can include a mushroom top member to further secure the mechanical jumper. The mechanical jumper is mounted to the vertical extension member to provide a stable and secure point of engagement when transferring power lines. This avoids electrocution to workers by no longer having to connect the mechanical jumper to flimsy solid jumpers and helps provide more uninterrupted power supply to consumers when installing new posts or shifting old posts to a new location.

A fuse including a housing having upper and lower portions, a plurality of terminal portions disposed in the lower portion, each of said terminal portions having first and second prongs and a gap therebetween, the gap narrowing from a first width adjacent an upper end of said first and second prongs to a second width adjacent a lower end of said first and second prongs, a fusible link disposed in the upper portion of the housing between said plurality of terminal portions, and a partition in said lower portion of said housing, wherein a distance between each of the second prongs and the partition increases from a first end of each of the second prongs proximate the upper portion to a second end of each of the second prongs distal from the upper portion for allowing the second ends to be displaced toward the partition before engaging the partition.

A network protector fuse is disclosed. A fuse is coupled to a fuse cover of the network protector fuse utilizing fasteners. Further, at least one captive fastener is inserted into the fuse cover and configured to couple the network protector fuse to a network protector. The at least one captive fastener is restricted from dislodging from the fuse cover.
