Abstract
Provided are a protecting device capable of safely and quickly interrupting a current path by restricting heat absorption to a lower case, and a battery pack using the same. A protecting device includes: a meltable conductor 3; and a housing 6 including a lower case 4 and an upper case 5, the housing being formed by joining the lower case 4 and the upper case 5, and the lower case 4 is provided with a recessed portion 23 having support portions 21 provided at opposing side edges of the recessed portion 23 and hollow portions 22 provided on the side edges substantially orthogonal to the side edges of the recessed portion 23 on which the support portions 21 are provided.
Claims25
A protecting device, comprising:
- a meltable conductor;
- and
- a housing including a lower case and an upper case, the housing being formed by joining the lower case and the upper case,
- wherein the lower case is provided with a recessed portion formed therein and support portions provided at opposing side edges of the recessed portion,
- further comprising:
- an insulating substrate on which the meltable conductor is mounted,
- wherein the support portions support first side edges of the insulating substrate crossing a current flow direction of the meltable conductor, and
- wherein the recessed portion includes hollow portions at side edges substantially orthogonal to the opposing side edges on which the support portions are provided such that second side edges different from the first side edges of the insulating substrate are held in a bridge-like manner.
A protecting device, comprising:
- a meltable conductor;
- and
- a housing including a lower case and an upper case, the housing being formed by joining the lower case and the upper case,
- wherein the lower case is provided with a recessed portion formed therein and support portions provided at opposing side edges of the recessed portion, and
- wherein the support portions are respectively provided at the opposing side edges of the recessed portion and protrude from the opposing side edges to the inside of the recessed portion.
