An electric device has an electric unit having a receiving region, a power supply unit received by the receiving region of the electric unit in a receiving direction, contact units for making an electrical connection between the power supply unit and said electric unit, unit for counteracting a motion of the contact units, which is movable relative to the electric unit in the receiving direction, relative to the power supply unit located on the receiving region, and within a region intended for the motion.
摘要:
A power supply module for interchangeable attachment to an electric tool has a module housing, which receives a battery and an introduction dome, 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 is located.
摘要:
The invention describes a battery pack having a housing and at least one battery cell. According to the invention, also provided are elements which compensates for tolerance variations of the battery cell(s). The tolerance compensation elements include at least one spreading element which is arranged in an intermediate space between at least two battery cells and/or between one battery cell and the housing.
摘要:
A pronounced heat-diffusing action for a battery pack, which has a plurality of battery cells (2) located in a housing (1), is created by shaping the wall of the housing (1) surrounding the battery cells (2) such that this wall forms at least one duct (3, 4) for a heat-diffusing medium, which duct is closed off from the interior of the housing (1).
摘要:
The invention relates to a device for locking electric appliances (2) with battery packs (4) for power supply, whereby the electric appliances (2) comprise a displaceable bolt (14; 36; 38; 40; 42) and the battery packs (4) comprise at least two recesses (24, 26) and the recesses (24, 26) are arranged serially behind each other in the direction of a relative movement of the electric appliance (2) and battery pack (4) and, after locking, the bolt (14; 36; 38; 40; 42) engages in one of the recesses (24, 26). According to the invention, the recesses (24, 26) have a different form or different dimensions or are offset perpendicular to the movement direction and that for various combinations of electric appliance (2) and battery pack (4), the form, the dimensions and/or offset of the recesses (24, 26) are matched to the form, dimensions and position of the bolt (14; 36; 38; 40; 42), such that the bolt (14; 36; 38; 40; 42) engages either only in the front recess (24), only in the rear recess (26), or sequentially firstly in the front and then in the rear recess (24, 26).
摘要:
The invention relates to a battery pack (2) for supplying an electrical appliance or an electromobile, especially a power tool, with power. Said battery pack comprises a plurality of battery cells (4) and at least one heat compensation element (18) interposed between neighboring battery cells (4). The invention is characterized in that the heat compensation element (18) consists of a plastic material.
摘要:
A battery pack for locking with a power tool with at least one movable locking bar has at least a front recess and a rear recess located after the front recess in the direction of a relative motion between the battery pack and the power tool, the recesses are configured as detent grooves, and the recesses are differently shaped and are offset transversely to the direction of motion; and a power tool locks with the battery pack.
摘要:
A battery pack with a device for locking said battery pack to a cordless power tool has a guide configured to guide the battery pack in a predetermined movement direction as it moves between a locking position in which it is locked to the cordless power tool and a removal position in which it is removed from the cordless power tool, the guide has a break in at least one location between the locking position and removal position, and at said location a force acting on the battery pack moves the battery pack into a safety position offset from the guide, in which the battery pack is prevented from moving further along the guide into the removal position.
摘要:
A toollessly makable and breakable electrical connection between a current source, in particular a removable energy storage device, and an electrical consumer, has at least one contact pair comprised of two contact elements, one of which is connected to the current source and one of which is connected to the consumer. In order to reduce the transition impedance in the contact pair and to reduce the current-induced heating of the contact pair, at least one contact element has a multitude of individual small-area contact points that are electrically connected in parallel. For example, the multitude of contact points is implemented in the form of fibers composed of an electrically conductive material, which are combined in bristle brush or paintbrush fashion to form a fiber brush.
