Abstract

Official abstract text for this publication.

A power shutoff device includes: a fuse to shut off conduction between the input portion connected to a power source side and the output portion connected to a load side; a box having a first face side with the input portion, the output portion, and the fuse to be assembled thereon; and a lock portion to fix one of the input portion and the output portion to the box. The one of the input portion and the output portion is integrally provided to the fuse. The other of the input portion and the output portion includes a first terminal portion integrally provided to the fuse and fixed to the box via a bolt, and a second terminal portion separately provided from the fuse and connected to the first terminal portion via a connecting member being attachable and detachable on a second face side of the box.

First claim

Opening claim text (preview).

What is claimed is: 1. A power shutoff device comprising: an input portion connected to a power source side; an output portion connected to a load side; a fuse disposed between the input portion and the output portion, wherein the fuse shuts off conduction between the input portion and the output portion by an overcurrent; a box having a first face side with the input portion, the output portion, and the fuse assembled on the first face side; a lock portion provided at the box, wherein the lock portion fixes one of the input portion and the output portion to the box; and a bolt, wherein the one of the input portion and the output portion is integrally provided to the fuse, wherein the other of the input portion and the output portion comprises a first terminal portion integrally provided to the fuse and fixed to the box via the bolt, and a second terminal portion separately provided from the fuse, wherein the first terminal portion and the second terminal portion are connected with each other by a connecting member which is attachable and detachable on a second face side of the box, and wherein the second face side of the box is located in a reverse side of the first face side of the box. 2. The power shutoff device according to claim 1 , wherein the first face side of the box is positioned downward in a direction of gravitational force with the power shutoff device assembled, and the lock portion supports a lower face of the one of the input portion and the output portion. 3. The power shutoff device according to claim 1 , further comprising a lever for attaching the connecting member to the box and detaching the connecting member from the box.
