Title:
CURRENT CUT-OFF DEVICE, AND WIRE HARNESS
Document Type and Number:
WIPO Patent Application WO/2017/135269
Kind Code:
A1
Abstract:
A flow path of current i1 is split into a plurality of flow paths by a splitting part (11). A first current cut-off circuit (12) including a fusible link is connected to one flow path (15). A second current cut-off circuit (13) including semiconductor switch circuits (13a, 13b) is connected to the other flow path (16). The resistance value of each circuit is adjusted such that the current i2 of flow path (15) and the current i3 of flow path (16) are at a fixed ratio. The cut-off current of the fusible link becomes smaller, and thus the electric wire diameters of an upstream electric wire (22) and a downstream electric wire (23) which need to match this current can be reduced. As a result of forming a parallel circuit in combination with the fusible link, an increase in the size of the external shape of the second current cut-off circuit (13) can be inhibited.
