Indicates the dimension between the tips of the protrusion that protrudes from.

Claims

[Claims for Utility Model Registration] An iron core laminate in which the ends of two laminates constituting the core are opposed to each other with a spacer interposed therebetween, and patch plates are applied to both sides of both laminates across the opposing ends. In an end-to-end isolation device, to account for variations in the core laminate thickness, the width of the spacer oriented in the direction of the laminate thickness should be set equal to the minimum variation in the core laminate thickness. or shorter, a protrusion protrudes from at least one of the opposite sides, and the dimension from the other opposite side to the tip of the protrusion is equal to or greater than the maximum variation value of the stacked thickness of the core. 1. An isolation device between ends of a core laminate, characterized in that at least one of the plates has a hole through which the protrusion passes.
