Title:
FUNCTION UNIT INTERLOCK MECHANISM
Document Type and Number:
WIPO Patent Application WO/2018/138881
Kind Code:
A1
Abstract:
[Problem] To obtain a function unit interlock mechanism that improves safety such that it is impossible to bring the operation handle of a wiring circuit-breaker of a function unit into the on-state while an insertion-extraction handle is inserted into an insertion-extraction handle insertion opening and it is also impossible to extract the function unit from a function unit storage space while the operation handle is in the on-state.
[Solution] A function unit interlock mechanism has a left opening/closing joint 19 and a right opening/closing joint 20 which are provided in a movable manner with respect to an insertion-extraction prevention body 14 in conjunction with an operation handle mechanism 17 connected to an operation handle 18 for switching between the on- and off-states of a wiring circuit-breaker. The left opening/closing joint 19 and the right opening/closing joint 20 are prevented from moving by the position of the insertion-extraction prevention body 14.
