Title:
ELECTRICAL APPARATUS USING BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2019/017184
Kind Code:
A1
Abstract:
According to the present invention, the output voltage of a battery pack is allowed to be switched and is shared by electrical apparatuses using different voltages. This electrical device, in which a series connection state and a parallel connection state of an upper cell unit 146 comprising five battery cells and a lower cell unit 147 can be automatically switched by means of a difference in a terminal shape on the electrical apparatus body side, has a terminal holder 550 which has an improved shape and holds a plurality of apparatus side terminals (572-578). The terminal holder 550, which establishes an electrically connected state with the connection terminals of the battery pack, is provided with two parallel protruding parts 566a, 566b that extend in the front-back direction, and second rail grooves fitted to the protruding parts 566a, 566b on the electrical apparatus side. Due to the fitting, relative movement of the terminal holder 550 and the battery pack in the vertical direction can be suppressed, and wear on the apparatus side terminals (572-578) can be greatly suppressed.
