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 fuse unit includes a fuse element which includes a fusible portion, a housing which accommodates the fuse element in a state that the fusible portion is exposed to an outside thereof, and a cover which is attached to the housing so as to cover the fusible portion. The cover includes a pair of side wall portions which is disposed so as to face each other with the fusible portion interposed therebetween, and a connection portion which connects the pair of side wall portions. The housing includes a guide wall which is configured to guide the cover toward the fusible portion when the cover is attached to the housing. The guide wall is inclined to a direction intersecting a separation direction in which the cover is separated from the housing.

A fuse line fixing structure of a fuse includes a base having first and second support sections. The first support section has two sides each forming a first wing and a first concave surface is formed between the first support section and the first wings. First and second electrodes are respectively arranged at two ends of the base. The first electrode includes a first curved plate arranged between the first support section and the first wings. The first curved plate has a convex engagement surface positioned against the first concave surface and a concave engagement surface facing toward an upper side of the first concave surface. The fuse line straddles between the first and second support sections and has an outer circumferential surface in mutual contact, through surface to surface engagement, with the concave engagement surface of the first curved plate.

Provided is a bus bar structure which may be suitable for reducing an occupied area of a printed circuit board (PCB) by removing a fuse from the PCB in an interconnect board (ICB) assembly of a battery pack. According to the present disclosure, the bus bar structure may include: bus bars which face each other and are arranged below the PCB in the ICB assembly of the battery pack; and a fuse case between the bus bars, wherein the fuse case includes a fuse wire therein and is configured to bring the fuse wire into contact with the bus bars via at least one end thereof.

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.
