電池用プロテクタ-
Document Type and Number:
Japanese Patent JP4608052
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a resistor for current detecting circuit from emitting smoke and enable miniaturizing a battery pack by mounting on a device for breaking circuit, one of the protection circuits for the battery pack, a resistor for current detecting circuit, whose abnormal heating can also fuse and break a fuse element of the device. SOLUTION: On a board I, there are provided a heater element 1 which is conducted with electricity to heat in abnormal circumferences as one of the circuit parts P contained in a battery pack, for a protection circuit against overcharge and over discharge, a resistor for a current detecting circuit as a part of the protection circuit, and fuse elements 31, 32 which are broken by an abnormal heating of either the resistor or the heater element 1.
