<P>PROBLEM TO BE SOLVED: To prevent improper connection of a bushing and a cable each having a different rated current value in a switch which allows for connection of a bushing and a cable by one-touch operation. <P>SOLUTION: Since the hole 12a of a central conductor 12 in the bushing body 10 is made shallow, a steel ball 25 is not pushed out even if the one-touch plug-in terminal 300 of a rated current 200A is inserted as far as it will go, and is not fitted in the groove 305a of a connection fitting 305. More specifically, the hole 12a is made shallower by an amount substantially equal to the diameter of the steel ball 25. Furthermore, the pin contact of the one-touch plug-in terminal corresponding to the hole 12a of a central conductor 12 is made shallower by an amount substantially equal to the diameter of the steel ball 25. <P>COPYRIGHT: (C)2012,JPO&INPIT |
