CIRCUIT PROTECTION DEVICE

摘要

A circuit protection device, including a conductor connected to first and second terminals and a spring exerting force on the conductor to move the conductor away from the first and/or second terminals when an over-voltage or over-temperature condition occurs within a charging circuit. One or more heat generating resistive elements melts material associated with one or more connection points of the conductor thereby releasing the conductor such that the spring moves the conductor to create an open circuit.

1. A circuit protection device comprising:
a substrate; a conducting layer disposed on said substrate, said conducting layer having a first terminal and a second terminal; a conductor disposed on said substrate, said conductor electrically connecting said first terminal and said second terminal creating a closed circuit between said first terminal and said second terminal during a normal operating condition; a low melting material disposed between said conductor and said first terminal and between said conductor and said second terminal; a resistive element disposed on said substrate; and a spring disposed on said substrate, said spring biased to displace said conductor during an abnormal circuit condition when said resistive element heats said low melting material creating an open circuit between said first terminal and said second terminal.
