EXTERNAL OPERATION HANDLE DEVICE OF CIRCUIT BREAKER
Document Type and Number:
Japanese Patent JP2018010811
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an external operation handle device of a circuit breaker, capable of reducing a component number of an assist mechanism and a manufacturing cost by reducing assembling man-hours, and thereby miniaturizing the size.SOLUTION: An external operation handle device comprises an assist mechanism 16 for helping the rotation of a handle grip 6 when rotating the handle grip in an OFF position direction from an ON position with a manual operation. The assist mechanism includes a cam member 18 that is arranged between a turn base 13 and a slide base 15, is rotatably coupled with an attachment base 4, and in which a turn base pin 14 is penetrated; and a roller 24 contacted with a cam surface 20 formed in a peripheral surface of the cam member. A spring force is accumulated and energized in an operation initiation in the OFF position direction from the ON position of the handle grip. The external operation handle device comprises a spring accumulation and energization discharging part that discharges the spring force after a middle operation of the OFF position direction from an ON position, and transfers a rotational torque in the OFF position direction to the handle grip.SELECTED DRAWING: Figure 6
