摘要:
A hand machine tool has a battery operated drive motor accommodated in a machine housing, with a battery housing mountable on said machine housing. The mounting of the battery housing of the machine housing is performed by two guiding strips arranged on the machine housing and engaging in guiding grooves provided in the battery housing. In a locking position, the battery housing is held by a spring-loaded slider which has two legs provided with end arresting projections form-lockingly engaged with stationary arresting projection provided on the battery housing, for locking the battery housing on the machine housing.

A hand machine tool with a battery operated drive motor has a plug coupling for electrical contacting of the drive motor with the battery unit mounted on the hand machine tool. The coupling includes a base provided at the machine side and displaceable relative to a machine housing. The base has contact springs which are in contact with contact surfaces provided on a plug housing of the battery unit. A centering element is located between the base and the plug housing and provides a fitting abutment between the contact springs and the contact surfaces.

An electric power tool and a power supply module for interchangeable attachment to an electric power tool are disclosed. The electric power tool has a tool housing (12) with a guide sleeve (15) for interchangeably receiving the power supply module (11), which has an introduction opening (152) and an electrical interface. To achieve high resistance to vibration of the contacting at the module/tool interface, at least one form-locking element (21) for making a form lock with the power supply module (11) is located in the end region, remote from the introduction opening of the guide sleeve (15). The power supply module (11) has a module housing (13), which receives a battery and an introduction dome (14), formed integrally onto the module housing, for guiding the tool, on which dome there is an electrical interface with the electric power tool and at least one form-locking element for making a form lock with the tool housing (15) is located (FIG. 2).

An energy storage module for current supply of an electrical apparatus, in particular for an electrical hand-held machining tool, has a plurality of cells for storage of electrical energy, at least one cell support mounting the cells, being in contact with the cells, enclosing the plurality of cells and made from a heat-conductive material, and at least one cooling body formed on the cell support.
摘要:
A monitoring device for an electrical machining tool, in particular for temperature monitoring with an accumulator-driven machine, includes a switch element (12) for separating an electrical consumer (14) from a current supply device (10). For detection of a first operating parameter (TMOTOR) of the consumer (14) and/or the current supply device (10), a first sensor (16) is provided, whereby the first sensor (16) is connected with a display unit and/or with the control input of the switch element, in order to control the switching process as a function of the first operating parameter (TMOTOR). Furthermore, the present invention relates to an electrical machining tool as well as a current supply device with the inventive monitoring device and a corresponding method of operation.
