The hand machine tool according to the invention has an integrated tool or a tool holderto receive a tool. An electric motorserves to drive the toolor the tool holder. A battery packfor supplying power to the electric motorcan be pushed into a guidein a first direction. A plurality of electrical contactsfor contacting counter contactsof the battery packare disposed in a contact holder. Wires, which are connected in each case to one of the electrical contacts, have cores which extend in a wave-like manner in the first directionadjacent to the electrical counter contact

Hand machine tool

An adapter apparatus for connecting a rechargeable battery to a power tool, containing a latching device for latching the adapter apparatus together with the power tool; and a locking device for locking the latching device is disclosed. The latching device is adjustable reversibly from a first position into a second position, wherein, in the first position, the adapter apparatus is firmly connected to the power tool and, in the second position, the adapter apparatus is detachable from the power tool, and the locking device is adjustable reversibly from a first position into a second position, wherein, in the first position, the locking device locks the latching device in the first position and, in the second position, the locking device does not lock the latching device and so the latching device is movable from the first position into the second position.

Self-locking latch of an adapter apparatus

A hand-held power tool, in particular a hammer drill or a combination hammer, is disclosed. The hand-held power tool includes a tool housing which has a receiving recess designed to replaceably receive a storage battery or a power supply unit. The hand-held power tool has an electric drive motor with a cooling fan. The tool housing has a first vent portion which is located in the receiving recess and through which a volume flow generated by the cooling fan can be guided.

Hand-held power tool, fanless storage battery

A connecting device for detachably connecting electrical connections, for example between a rechargeable battery and an electrical power tool or a rechargeable battery and a charging device. The connecting device includes a carrier unit and at least one receptacle connectable to the carrier unit. A receptacle as part of and for connection to a connecting device. A carrier unit as part of a connecting device and for accommodating at least one receptacle.

Multi-contact plug on rail

A hand-held machine tool has an integrated tool or a tool holder to receive a tool. An electric motor drives the tool or the tool holder. A battery pack for supplying power to the electric motor can be pushed into a guide in a first direction. Electrical contacts are disposed in a contact holder being offset with respect to each other in a second direction. A mounting for the contact holder holds the contact holder so that it can move in the first direction-and in a third direction with respect to the mounting. The first direction, second direction and third direction are orthogonal to each other in pairs. A spring acts upon the contact holder with a force opposite to the first direction. An end face oriented opposite to the first direction is provided with a centerer which cooperates with a centering support on the battery pack in order to prevent a relative movement between the end face and the battery pack in the third direction.

Hand-held machine tool

An accumulator package () for a hand-held power tool includes:

Accumulator package with charge state display

A suction device () for a hand-held power tool and which is releasably connected with the power tool, includes a suction blower wheel () for producing a suction air stream in a suction path (S) and located in the device housing (), a rolling bearing () for supporting the suction blower wheel () in the device housing (), a blower shaft () for driving the suction blower wheel (), and a drive coupling () for rotatably frictionally connecting the blower shaft () with the drive shaft () of the hand-held power tool () in a connected condition of the drive shaft () with the blower shaft ().

Suction device

A drilling tool, including a housing (,), a suction device (,), and at least one gas spring (,) cooperating with both the housing (,) and the suction device (,) and an operational direction of which is parallel to a drilling direction, with the housing (,) having bore (,) for receiving a piston rod (,) and at least a section of cylinder (,) of the at least one gas spring (,).
