초록 ▼

A power plug locking device includes a lock unit that restricts movement of an operation arm arranged on a power plug. The lock unit includes a first member, which is moved between a lock position and an unlock position, and a second member, of which movement is restricted in accordance with the movement of the first member. The second member restricts the movement of the operation arm in cooperation with the first member that is moved to the lock position. The first member includes a first contact surface. The second member includes a second contact surface that is able to contact the first member that is moved to the lock position. At least one of the first contact surface and the second contact surface includes a stepped shape.

대표청구항 ▼

1. A power plug locking device that prevents unauthorized removal of a power plug from an inlet, wherein the power plug includes an operation arm that is able to be hooked to the inlet, the power plug locking device comprising: a lock unit that restricts movement of the operation arm when the operation arm is hooked to the inlet, wherein the lock unit includes: a first member moved between a lock position and an unlock position; anda second member of which movement is restricted in accordance with the movement of the first member, wherein the second member restricts the movement of the operation arm in cooperation with the first member that is moved to the lock position, wherein: the first member includes a first contact surface;the second member includes a second contact surface that is able to contact the first contact surface of the first member that is moved to the lock position; andat least one of the first contact surface and the second contact surface is formed with a stepped shape. 2. The power plug locking device according to claim 1, wherein the stepped shape includes a plurality of steps formed at different heights. 3. The power plug locking device according to claim 1, wherein: the stepped shape includes a first step and a second step formed at different heights on the first contact surface of the first member;the first contact surface includes a reference surface formed at a height that differs from the first and second steps; andthe lock position includes three positions of: a position at which the first step faces toward the second contact surface;a position at which the second step faces toward the second contact surface; anda position at which the reference surface faces toward the second contact surface. 4. The power plug locking device according to claim 1, wherein the lock unit includes a coupling movement member coupled to the first member and is movable as a seat for the first member,the power plug locking device further comprises an absorption unit including an urging member arranged between the coupling movement member and the first member to urge the first member to the lock position,when the operation arm is incompletely hooked to the inlet thereby obstructing movement of the first member in a lock direction with the second member, the absorption unit absorbs stress applied to the first member in an unlock direction and permits movement of the coupling movement member in the lock direction relative to the first member. 5. The power plug locking device according to claim 1, further comprising an electric driving device that moves the first member to the lock position or the unlock position.
