Abstract
Provided are a protecting device and a battery pack capable of preventing floating of a blowout member, preventing deformation of a meltable conductor, and maintaining predetermined current capacity and blowout properties. The protecting device 1 includes: a meltable conductor 2; and a blowout member 4 connected to one surface of the meltable conductor 2, wherein the blowout member 4 includes: an insulating substrate 3; and a deformation suppressing electrode 5 formed on a front surface 3a connected to the meltable conductor 2 of the insulating substrate 3 and connected to the meltable conductor 2 to suppress deformation of the meltable conductor 2.
Claims10
A protecting device, comprising:
- a meltable conductor;
- and
- a blowout member connected to one surface of the meltable conductor,
- wherein the blowout member comprises an insulating substrate and plurality of deformation suppressing electrodes formed on a front surface of the blowout member,
- wherein the insulating substrate and the deformation suppressing electrodes are connected to the meltable conductor and thereby provide for suppression of deformation of the meltable conductor,
- wherein each deformation suppressing electrode comprises a plurality of small electrodes at a connection portion with the meltable conductor,
- wherein each side of the meltable conductor is attached to a respective deformation suppressing electrode via the plurality of small electrodes on each side of the meltable conductor, and
- wherein the plurality of deformation suppression electrodes are configured to suppress deformation in the meltable conductor before the meltable conductor melts.
