Abstract

Provided are: a plug body including a main body housing, a fuse having a pair of terminals protruding outside the main body housing with the fuse being accommodated in the main body housing, and a cover attached to the main body housing; a circuit accommodating body configured to accommodate a pair of terminals on a mating side connected to the pair of terminals of the fuse; a rotatable lever connected to the plug body and the circuit accommodating body and configured to connect and disconnect between the pair of terminals of the fuse and the pair of terminals on the mating side; and a fuse biasing portion configured to bias the fuse accommodated in the main body housing toward the cover.

First claim

What is claimed is:

1. A fuse securing structure for a power source circuit cutoff device, comprising:
a plug body comprising a main body housing, a fuse having a pair of terminals protruding outside the main body housing with the fuse being accommodated in the main body housing, and a cover attached to the main body housing;
a circuit accommodating body accommodating a pair of terminals on a mating side connected to the pair of terminals of the fuse;
a rotatable lever operating to rotate while being connected to the plug body and the circuit accommodating body through a cam mechanism, engaging or disengaging the plug body and the circuit accommodating body by a cam thrust force of the cam mechanism, and connecting and disconnecting between the pair of terminals of the fuse and the pair of terminals on the mating side; and
a fuse biasing portion biasing the fuse accommodated in the main body housing toward the cover is provided,
wherein the fuse biasing portion is an elastically deformable arm portion provided in the main body housing,
wherein the arm portion abuts a lower surface of at least one of the pair of terminals of the fuse accommodated in the main body housing to bias the at least one of the pair of terminals toward the cover to hold the terminal between the arm portion and the cover with the cover abutting an upper surface of the at least one of the pair of terminals,
wherein at least one of the pair of terminals of the fuse has a cutout retaining a jig upon mounting of the fuse, and
wherein the main body housing has a retaining portion retaining the cutout upon the fuse being mounted to the main body housing to prevent disconnection of the fuse.

2. The fuse securing structure for a power source circuit cutoff device according to claim 1 , further comprising an excessive displacement preventing rib provided at a position facing flexure of the fuse biasing portion and controlling excessive flexure of the fuse biasing portion.
