Abstract

본 발명은 밧데리 과방전 보호회로가 내장된 충전용 전기드릴에 관한 것으로써, 특히 상기 전기드릴의 무리한 사용으로 밧데리가 과방전되어 재충전이 되지 않는 문제점을 방지하도록 적합하게 전기드릴 내부에 밧데리 과방전 보호회로를 내장한 밧데리 과방전 보호회로가 내장된 충전용 전기드릴인 것이다.The present invention relates to an electric drill for charging with a built-in battery over-discharge protection circuit, in particular the battery over-discharge inside the electric drill suitably to prevent the problem that the battery is over-discharged and not recharged due to excessive use of the electric drill Battery with built-in protection circuit An electric drill for charging with built-in over-discharge protection circuit.

상기와 같은 본 발명 밧데리 과방전 보호회로가 내장된 충전용 전기드릴은 밧데리 팩의 단자는 밧데리팩 클립홀더에 의해 지지되고 있는 밧데리 팩클립에 접속되며, 상기 밧데리 팩클립 끝단에는 리드와이어와 마운팅되며, 상기 리드와이어 다른 한쪽 끝단은 스위치 입력단자에 연결되며, 상기 스위치 출력단자는 상기 리드와이어를 통하여 밧데리의 과방전보호를 위한 방전종지전압검출 및 차단부의 입력단자에 접속되며, 상기 방전종지전압검출 및 차단부의 출력측단자는 상기 리드와이어에 의해 모터에 극성이 맞도록 접속됨을 특징으로 한다.The electric drill for charging the battery with the over discharge protection circuit of the present invention as described above is connected to the battery pack clip, the terminal of the battery pack is supported by the battery pack clip holder, the battery pack clip end is mounted with a lead wire The other end of the lead wire is connected to the switch input terminal, and the switch output terminal is connected to the discharge end voltage detection and the input terminal of the breaker for overdischarge protection of the battery through the lead wire. The output side terminal of the breaker is connected to the motor by the lead wire so as to match the polarity.
