Electric connection box

1. An electric connection box comprising:

a fuse cavity, made of synthetic resin, into which a fuse can be inserted from an upper side, the fuse including a pair of fuse terminals, a fusible element electrically connecting the fuse terminals, and a housing made of synthetic resin and accommodating the fuse terminals so as to cover the fusible element; and

a pair of cavity terminals configured to come in contact with the fuse terminals to be electrically connected thereto when the fuse is inserted into the fuse cavity,

wherein a lower face of the housing of the fuse inserted in the fuse cavity is configured to abut against an inner bottom portion of the fuse cavity, so that the fuse is positioned in the fuse cavity in a downward direction;

wherein the inner bottom portion has a non-projecting portion and a projecting portion formed on an inner bottom face of the inner bottom portion, the projecting portion extending upwardly from the inner bottom face more than the non-projecting portion;

wherein an upper face of the projecting portion abuts against the lower face of the housing;

wherein an empty space is formed between an upper face of the non-projecting portion and the lower face of the fuse housing;

wherein the inner bottom portion is in a range of the height of a pair of opposing side walls of the fuse cavity;

wherein the non-projecting portion is formed in a plane; and

wherein a total area of the non-projecting portion is more than or equal to a total area of the upper face of the projecting portion.

2. An electric connection box as set forth in claim 1 , wherein

the projecting portion is provided at the inner bottom face between the cavity terminals when the fuse cavity is viewed from the upper side, and

the projecting portion is located right beneath the fusible element of the fuse accommodated in the fuse cavity.

3. An electric connection box as set forth in claim 2 , wherein the fuse is a slow blow fuse.

4. An electric connection box as set forth in claim 1 , wherein

the projecting portion is projected on the inner bottom face so that the empty space is formed between the lower face of a portion of the housing of the fuse located right beneath the fusible element and the inner bottom face of the fuse cavity, in a state where the fuse is accommodated in the fuse cavity.

5. An electric connection box as set forth in claim 4 , wherein the fuse is a slow blow fuse.

6. An electric connection box as set forth in claim 1 , wherein the fuse is a slow blow fuse.

7. An electric connection box as set forth in claim 1 ,

wherein the projecting portion comprises a pair of pedestal members disposed respectively at the opposing side walls of the cavity, and an elongated member disposed between and interconnecting the pedestal members.

8. An electric connection box as set forth in claim 7 , wherein a top surface of the pedestal members and a top surface of the elongated member extend along a same plane.

9. An electric connection box as set forth in claim 8 , wherein the fuse cavity comprises a plurality of bottom corners and the inner bottom face is formed at the bottom corners of the fuse cavity along a bottom plane which is below the same plane of the top surfaces.

10. An electric connection box as set forth in claim 1 ,

wherein the total area of the upper face of the projection portion which abuts against the lower face of the housing is less than the total area of the non-projecting portion.
