PROBLEM TO BE SOLVED: To quickly restore a circuit and electrical communication after the breakage of a conductor. SOLUTION: A spare bus bar 60 which is capable of being inserted between restoration parts 49 of a bus bar 17 is fixed in the rear face of a cover body 51 and is normally housed in a housing space 48 in a lower case 1 by putting the cover body 51. When an emergency occurs, an explosive is exploded by a signal from a trigger wire 19, and the bus bar 17 is ruptured due to the explosive force, and the circuit is broken. After that, in order to restore the circuit and electrical communication, the cover body 51 is disassembled and the position is deviated and an insertion part 62 of the spare bus bar 60 is inserted into the restoration part 49 which is positioned in both sides of the ruptured part of the bus bar 17. Consequently, the circuit and the electrical communication are restored. |
