Fuse cavity and electric junction box equipped therewith
View Patent ↗A low-profile fuse ( 10 ) includes a tab terminal ( 15 ) provided at an end of a fuse element ( 17 ), and a protective projection ( 12 ) provided in a middle part ( 11 c ) of a fuse body ( 11 ) for protecting the fuse element ( 17 ). Said low-profile fuse ( 10 ) is adapted to a housing ( 50 ) of a fuse cavity ( 55 ). Guides ( 67 A), ( 67 B) is provided on the housing ( 50 ) for preventing the low-profile fuse ( 10 ) from being inserted obliquely into the housing ( 50 ). Said guides ( 67 A), ( 67 B) of the housing ( 50 ) are allowed to make contact with the protective projection ( 12 ) of the fuse ( 10 ). Slopes ( 67 c ), ( 67 d ), ( 67 e ), ( 67 f ) are provided on the guides ( 67 A), ( 67 B). The guides ( 67 A), ( 67 B) are taller than the terminal ( 30 ) mounted on the housing ( 50 ). This fuse cavity is provided in an electric junction box ( 1 ).
1. A fuse cavity having a housing to receive a fuse, comprising:
said fuse includes a fuse element;
terminals provided at both ends of the fuse element; and
a fuse body,
characterized in that a protecting projection protrudes from a middle part of said fuse body for protecting the fuse element and is disposed on said fuse body intermediate the terminals on the ends of the fuse element, and
that said housing has a guide formed at a side wall of an inner part thereof, said guide being allowed to contact with said protecting projection of the fuse body so as to prevent said fuse from being inserted obliquely into the housing.
2. The fuse cavity as described in claim 1 , wherein a slope is provided at the guide of said housing.
3. The fuse cavity as described in claim 2 , wherein the guide of said housing is made taller than the terminal mounted on the housing.
4. The fuse cavity as described in claim 1 wherein the protecting projection is formed as an insulating housing in a substantially rectangular box shape.
