PURPOSE: A bus bar connection mechanism of a gas insulation switch is provided to enhance contact combination force between bus bars by using an extension housing, a flange housing, and a tulip contact assembly. CONSTITUTION: An insulator housing(12) of an insulator is inserted into an end portion of the first bus bar(14). The first bus bar(14) is fixed and installed on an inner wall of the first outer case(18). A contact connection portion between the first and the second bus bars(14,16) includes a tulip contact assembly(10) having a plurality of tulip contact sections(10A) and a ring spring(10B). The tulip contact sections(10A) are distributed along a circumference direction. The ring spring(10B) is formed on the circumference of the tulip contact sections(10A). An extension housing(2) is formed between the first and the second outer cases(18,20) by using a welding bolt(40) and a nut(44). A flange housing(4) is formed between the first and the second outer cases(18,20) by using a welding bolt(42) and a nut(46).
