    • A cordless system has cordless system components that include a cordless device, such as a cordless power tool, a battery pack and a charger. The battery pack is mated with either the cordless device to provide power to operate the cordless device or to the charger to charge the battery cells in the battery pack. In an aspect, the cordless system has an identification and communication system by which the battery pack identifies and communicates information about the battery pack to the cordless device or to the charger to which the battery pack is mated. In an, the battery pack of the cordless system is capable of multiple modes, such as controlling the cordless device and controlling the charger. In an aspect, the battery pack validates the cordless device or charger to which it is mated. in an aspect of the invention, the cordless system uses any of a wired interface, radio frequency interface, an optical interface or a magnetic interface to communicate information between the battery pack and the cordless device or charger to which the battery pack is mated. In an aspect, female terminals are used in a terminal block of the battery pack to protect against foreign objects contacting the terminals. In aspect, the terminals in the terminal block of the battery pack are staggered or scattered to reduce the likelihood of a short circuit. In an aspect of the invention, the battery pack has a trap door that closes when the battery pack is not mated to a cordless device or charger to protect the terminal block of the battery pack. In an aspect of the invention, multi-spring, split contact terminals are used in the terminal block of at least one of the cordless system components. In an aspect of the invention, the battery cells are Lithium Ion battery cells.
    • 无绳系统具有无绳系统组件,其包括无绳设备,例如无绳电动工具,电池组和充电器。 电池组与无绳设备配合,以提供电力来操作无绳设备或充电器来对电池组中的电池单元进行充电。 一方面,无绳系统具有识别和通信系统,通过该系统,电池组将电池组的信息识别并传送到无绳装置或与电池组配合的充电器。 一方面,无绳系统的电池组能够具有多种模式,例如控制无绳装置并控制充电器。 在一方面,电池组验证其配合的无绳设备或充电器。 在本发明的一个方面,无绳系统使用有线接口,射频接口,光接口或磁接口中的任何一个来在电池组与电池组配对的无绳设备或充电器之间传送信息。 在一方面,阴端子用于电池组的端子块中,以防止与端子接触的异物。 在一方面,电池组的端子块中的端子交错或分散以减少短路的可能性。 在本发明的一个方面中,当电池组不与无绳装置或充电器配合以保护电池组的端子块时,电池组具有闭合的收集门。 在本发明的一个方面,在至少一个无绳系统部件的端子块中使用多弹簧分离接触端子。 在本发明的一个方面,电池单元是锂离子电池单元。

    • A power tool is provided which accommodates interchangeable tool heads. The power tool includes: a tool body having a housing and an electric motor mounted within the housing, as well as a tool head that releasably attaches via a mechanical connection and an electrical connection to the tool body. The tool releasably connects to the output shaft of the electric motor when the tool head is attached to the tool body. A tool switch interposed between a power source for the electric motor and the electric motor is operable to supply power from the power source to the electric motor. A tool accessory switch interposed between the tool accessory and the power source for the electric motor is operable to supply power from the power source via the electrical connection to the tool accessory, thereby providing the tool operator independent control of the tool accessory.
    • 提供了一个电动工具,可容纳可互换的工具头。 该电动工具包括:工具主体,该工具主体具有壳体和安装在该壳体内的电动机,以及工具头,该工具头通过机械连接和电连接可释放地附接到工具主体。 当工具头连接到工具主体时,该工具可松开地连接到电动机的输出轴。 插入在用于电动机的电源和电动机之间的工具开关可操作以从电源向电动机提供动力。 插入在工具附件和用于电动机的动力源之间的工具附件开关可操作地通过电连接向电动工具附件提供来自动力源的动力,从而为工具操作者提供独立的工具附件控制。
