Abstract
Abstract A device for charging a rechargeable electric power source comprises a first section and a second section capable of being assembled in two positions relative to each other, one of such positions being a rest position and the other of such positions being a charging position, the first section being formed to receive a rechargeable electric power source. Electric components are arranged in the second section as a charging circuit for charging a rechargeable electric power source. Connector pins are provided on the second section for cooperating with an electric mains socket, the connector pins being connected to the electric components of the charging circuit. In the rest position the connector pins are covered by the first section. In the charging position the connector pins are clear of the first section, and the rechargeable electric power source in the first section is electrically connected to the electric components of the charging circuit in the second section. A flexible electrical contact member is arranged in the first section for exerting pressure against the rechargeable electric power source.
