PROBLEM TO BE SOLVED: To prevent an unexpected accident by covering a conductive part of a trip lock terminal.SOLUTION: The trip lock terminal comprises: a proximal-end-side insulation part extending from a board surface of a protection relay device; a shaft-shaped conductive part extending from the proximal-end-side insulation part; a distal-end-side insulation part that is fixed to a distal end of the conductive part; and a fixing member that is provided in a movable manner in a shaft center direction relatively to the conductive part. In the trip lock terminal, a short-circuit piece can be fixed by the fixing member and the proximal-end-side insulation part. The trip lock terminal also comprises: a first cover that covers the conductive part between the fixing member and the proximal-end-side insulation part and is provided in a movable manner in the shaft center direction of the conductive part; a first energization member that is mounted within the proximal-end-side insulation part and presses the first cover to the fixing member; a second cover which covers the conductive part between the fixing member and the distal-end-side insulation part and is provided in a movable manner in the shaft center direction of the conductive part; and a second energization member which is provided within the distal-end-side insulation part and presses the second cover to the fixing member.SELECTED DRAWING: Figure 1 |
