A power-supply breaker apparatus of the present invention includes a fuse provided between a power supply and a load in an electric circuit, an apparatus main body for housing the fuse, a pair of main body side terminals, a plug housing chamber for housing the plug in the apparatus main body movably in a fitting/detaching direction, and a pair of plug side terminals which become conductive with each other in the plug. The electric circuit is electrically conductive via the fuse, and the pair of main body side terminals are supported to the apparatus main body movably in a direction crossing substantially perpendicularly to the fitting/detaching direction, and one of the pair of the main body side terminals is connected with the power supply, and the other terminal is connected with the load. Moreover, when the plug is moved in the fitting/detaching direction, the pair of plug side terminals are freely fitted into and detached from the pair of main body side terminals.

A power breaking device 20 includes a stationary box 21, a fuse carrying box 23 and a guide and restricting mechanism 25. The stationary box 21 consists of a fixed housing 26, a load-side bus bar 27 and a power-side bus bar 28. The fuse carrying box 23 consists of a carrying box body 60 detachable to the stationary box 21 and a fuse fixing part 61 for carrying a fuse 22. The mechanism 25 is constituted by slits 41, 41 formed in a partition wall 34. The partition wall 34 is formed integrally with the fixed housing 26 to define an accommodating part 39 in which the fuse 22 is accommodated and retained. When the fuse carrying box 26 is fitted to the stationary box 21, the slits 41, 41 serve to introduce both terminals 24, 24 of the fuse 22 to a power-connecting part and a load-connecting part of the stationary box 21 and also restrict the displacement of the terminals 24, 24.

A power-supply breaker apparatus of the present invention includes a fuse provided between a power supply and a load in an electric circuit, an apparatus main body for housing the fuse, a first bus bar whose one end is fixed to one fuse terminal of the fuse, a second bus bar having one end fixed to one of the power supply and the load, a plug housing chamber for housing the plug in the apparatus main body movably in a fitting/detaching direction, and a pair of plug side terminals which become conductive with each other in the plug. The other end of the first bus bar is extended so as to be composed as one terminal of the pair of main body side terminals, and the other end of the second bus bar is extended parallel with the first bus bar so as to be composed as the other terminal of the pair of main body side terminals. Respective terminal insertion widths of the pair of plug side terminals are wider than corresponding widths of the pair of main body side terminals.

A power supply shut-off apparatus 10 includes a fuse-accommodating box 14, a power supply-side bus bar 15, a load-side bus bar 16, and a plug 18 for connecting a power supply and a load through a fuse 13. A mounting portion 17 is provided with an insulation wall 11, a terminal 16a of the power supply-side bus bar 16 is located on one surface side of the insulation wall 19, and a terminal 11 of the fuse 13 is located on the other surface side of the insulation wall 19. The plug 18 is formed of a plug housing 49 and a terminal member 50 having a U-shaped cross section, the terminal member 50 is mounted astride the insulation wall 19 for electrically connecting the terminals 11, 12 of the fuse 13 to either one of terminals 15a, 16b of the power supply-side bus bar 15 and the load-side bus bar 16. The insulation wall 19 is provided with wobble-suppressing means 20 for preventing each of the terminals 11, 12 from moving from a wall surface of the insulation wall 19 and preventing each of the terminals 11, 12 from wobbling.

In the case where a braid (14) is used as a shielding sheet covering wires (10) over their entire length, a distal end portion of the braid (14) is connected to a mounting member (B) connected to the ground (G), thereby achieving an electromagnetic shielding conduction. At this time, the distal end portion (14a) of the braid (14) is spread outward, and is engaged in an annular groove (20b) of a channel-shaped cross-section in a housing (20), and a braid retaining band (22) is wound on an outer surface of the distal end portion (14a) of the braid (14), and is tightened to fasten this distal end portion. As a result, the distal end portion (14a) can be positively and firmly connected to the mounting member (B), and the effective electromagnetic shielding effect can be expected, and the stable electrical characteristics can be obtained, so that the reliability of the connection can be enhanced.
