Abstract:
1. A protection circuit module of a rechargeable battery, the module comprising: a substrate formed of a flexible insulator and comprising a circuit supporting unit and a wiring supporting unit formed on a first surface of the substrate and extending from the circuit supporting unit; a conductive circuit pattern unit formed on the circuit supporting unit; a conductive wiring unit formed on the wiring supporting unit, wherein the wiring unit is electrically connected to the circuit pattern unit and extends along the wiring supporting unit; circuit elements electrically connected to the circuit pattern unit and formed on one surface of the circuit supporting unit; a reinforcement unit made of a hard insulating substrate formed on an opposing surface of the circuit supporting unit so as to have the same area as the circuit supporting unit and supporting the circuit supporting unit wherein the reinforcement unit is directly mounted on the opposed surface of the circuit supporting unit; a protection layer formed on the one surface of the substrate and covering the circuit pattern and wiring unit wherein the protection layer comprises an insulating film formed on the one surface of the substrate so as to have the same area as the circuit supporting unit; and conductive terminal connection units, each terminal connection unit comprising one end connected to the circuit pattern unit and an opposing end formed at an edge of the circuit supporting unit, wherein the protection layer, the circuit supporting unit, and the reinforcement unit comprise openings formed at a first edge of the protection layer, the circuit support unit and the reinforcing unit and extending inward therefrom so as to be aligned and corresponding to the terminal connection units and exposing the terminal connection units.
