FIG. 1 is a circuit breaker using an interlock fitting according to an embodiment of the present invention, wherein (a) is a plan view and (b) is a side view of FIG. FIG. 2 is an enlarged view of the modified hole of FIG. The circuit breakers 11, 12 are fixed side by side by means (not shown) with only the operation units 11a, 12a protruding from the upper surface of the panel 21. A base 1 having a long deformed hole 2 formed on the left and right is arranged between the two circuit breakers 11 and 12, and the base foot 1 a is fixed to the panel 21 with screws 31. One end of the lever 16 has one circuit breaker 1
A concave portion 2a where the shaft 17a is fixed at a position facing the operating handle 12a of the second circuit breaker; and a concave portion 2c where the shaft 17a is fixed at a position where the other end of the lever 16 faces the operating handle 11a of the other circuit breaker 11. A recess 2b is provided at one end of the lever 16 on the operating handle 12a of the one circuit breaker 12, and at the position where the other end of the lever 16 faces the operating handle 11a of the other circuit breaker 11, the shaft 17a is fixed. Have been. FIG.
Similarly, a thin shaft of the fixing member 17 penetrating through the modified hole 2 is formed with a screw and screwed with a screw hole of the lever 16. The lever 16 can be moved in the H direction by a fixing bracket 17, and is fixed at a position where one or both of the operation breakers 11a and 11b are not turned ON. In this mechanical interlock configuration, when the thin shaft 17a of the fixing bracket 17 is inserted into the concave portion 2a of the modified hole 2, only the operation of the circuit breaker 12 cannot be performed. In this state, operation of the circuit breaker 12 is impossible even if the lever 16 is touched or receives vibration. Fixing fixture 17 to recess 2
When fixed at the position c, only the operation of the circuit breaker 11 cannot be performed, and the function of the lever 16 is the same. When the left and right circuit breakers 11 and 12 are both to be turned off, the same function is obtained by fixing the fixing bracket 17 to the recess 2b.
