Abstract
A cable for a battery includes a conductive member that extends in a longitudinal direction of the cable, an expansion member spaced with the conductive member, and an insulation member covering the periphery of the conductive member and the expansion member. The insulation member has a through hole. The expansion member is configured to expand and overflow to the outer surface of the insulation member through the through hole when the temperature reaches a threshold.

A cable for a battery, comprising:
- a conductive member extending in a longitudinal direction of the cable;
- an expansion member spaced with the conductive member;
- and
- an insulation member covering a periphery of the conductive member and a periphery of the expansion member, the insulation member having a through hole;
- wherein:
- the expansion member is configured to expand and overflow to an outer surface of the insulation member through the through hole when a temperature of the expansion member reaches a threshold;
- and
- the expansion member comprises an insulating expansion body and a wrapping member covering the insulating expansion body, a melting point of the wrapping member is lower than a melting point of the insulation member, the wrapping member is configured to melt when the temperature of the expansion member reaches the threshold, and the insulating expansion body is configured to expand and overflow to the outer surface of the insulation member through the through hole when the wrapping member melts.
