Figure 3, which will be described later, shows the details of the part shown in the dashed-dotted circle A, and is a side view of the circuit breaker seen from the front right side. Fig. 2 is a side view showing the state in which the circuit breaker is pulled out to the disconnection position of the switchboard without a connector attached, and Fig. 3 is a side view showing the state in which the circuit breaker is pulled out to the disconnection position of the switchboard. It is a side view which shows the conventional example of the connector which connects and disconnects a circuit. 1... Switchboard, 1a... Bottom plate, 2... Circuit breaker,

Claims

[Scope of utility model registration request]

Attaching and detaching a connector consisting of a first connector provided on the front surface of the circuit breaker and a second connector provided on the distribution board side, which connects and disconnects an auxiliary circuit for operating control of the circuit breaker that is stored and drawn out in the distribution board. An interlock device for regulating the circuit breaker, comprising: a support protruding from the front surface of the circuit breaker and provided near the bottom of the first connector; and a mounting hole formed into a substantially right-angled isosceles triangular plate shape and provided substantially near the center of gravity of the support. is rotatably supported at the tip of the support by a fulcrum shaft provided horizontally orthogonally to the direction of storage and withdrawal of the circuit breaker into the switchboard, and is engaged with a locking plate provided on the bottom plate of the switchboard. a biasing mechanism that biases the interlock lever against the support in a counterclockwise direction when viewed from the right side of the front surface of the circuit breaker; The second connector is provided with an engaging portion for a peripheral edge of the connector, is supported on the front surface of the first connector so as to be movable in the direction of storage and drawout of the circuit breaker in the switchboard, and is constantly urged and connected in the pullout direction. An interlock device for a circuit breaker auxiliary circuit connector, comprising an interlock base that detaches from the interlock lever when pushed in.
