Abstract: Provided is an electric device capable of suppressing vibration of a battery pack. Included are: a first housing 21 accommodating a load portion that consumes electric power; a second housing 22 having one end portion connected to the first housing 21 and another end portion to which a battery pack 9 is connectable; and an elastic member 40 interposed between the first housing and the second housing. The first housing includes a first restricting portion 42 positioned away from the elastic member, and the second housing includes a second restricting portion 44 positioned away from the elastic member and engageable with the first restricting portion.

Abstract: In order that the output voltage of a battery pack can be switched and the battery pack can be shared among different voltage electric appliances, this battery pack has a switching mechanism that switches outputting a low voltage by parallel connection of two cell units or outputting a high voltage by series connection of the two cell units, said two cell units each being composed of a plurality of cells connected in series, wherein the switching mechanism is configured from a change-over switch having an operation lever (452). The change-over switch is embedded in a battery pack (400), and an operator is able to manually switch outputting 18 V by setting the operation lever (452) at a first position or outputting 36 V by setting the operation lever (452) at a second position.

Abstract: A battery pack houses first and second cell units that are composed of a plurality of cells, and has a positive electrode power source terminal and a negative electrode power source terminal. This battery pack is provided with a series connector capable of connecting, in series, the first and second cell units and a parallel connector capable of connecting, in parallel, the first and second cell units, and is capable of switching between a parallel connection voltage and a series connection voltage. In the case of attachment to the high voltage electrical device body, the series connector becomes conductive and the parallel connector pair is cut off by the action of the series/parallel switching terminal. In the case of attachment to a low voltage electrical device body, the state is returned to an initial state, the series connector is cut off, and the parallel connector pair becomes conductive.

Abstract: In an upper cell unit (2146) and a lower cell unit (2147) comprising five battery cells, positive electrode terminals (2162, 2172) are set apart and aligned vertically, and negative electrode terminals (2167, 2177) are set apart and aligned vertically. When an electrical device body is rated at 36V, device-side terminals are in contact only at the upper terminals (2162, 2167), and short circuiting of the lower terminals (2172, 2177) is effected using a short bar 2059. When the electrical device body is rated at 18V, the upper and lower terminals (2162 and 2172, 2167 and 2177) are simultaneously made to contact the device-side terminals, and the upper cell unit (2146) and the lower cell unit (2147) assume a parallel connected state. Thus, it is possible to automatically switch the output voltage when a battery pack is mounted according to the difference in terminal shape on the electrical device body side.
