Power supply interrupting device for electric vehicles, includes detachable fuse box inserted into stationary box such that fuse terminals contact elastic connection of load and power supply side bus bars

摘要

The fuse box (23) accommodates fuse (22) inside fixed portion (61). The fuse box is detachably inserted into a stationary box (21). The load and power supply bus bars (27,28) in the housing (26) of the stationary box have elastic connections (49,54) which are contacted by fuse terminals (24) during insertion of fuse box. A guide (25) regulates connection between fuse terminals and the elastic connection. A barrier plate (34) with a slit (41) is provided corresponding to the insertion position of the fuse in the housing (26). The fuse terminals pass through the slits and contact the elastic connections of the bus bars. The fuse box is removed from the stationary box to disconnect load and power supply.
