The plug 140 is configured to connect the thermal fuse 120 with a battery management system, and the battery management system may apply a certain voltage to the thermal fuse 120 in the detection cable 100 through the plug 140, and determine whether the thermal fuse 120 is fused or not through the detection voltage or current, so as to determine whether a thermal runaway event occurs in the battery module 10 in which the detection cable 100 is located.
Further, in some possible implementations, the plug 140 may include a housing and conductive plug contacts with the plug 140. The housing is coupled to the inner core wire 110 and/or the outer insulating layer 130 to provide good mechanical strength.
