Abstract

The electrical connection box includes a case, a frame that is made of a synthetic resin and whose position is fixed relative to the case, fixed terminals that are fixed to the frame and can be connected to external terminals, a fuse having terminals that are put over the fixed terminals, stud bolts for fastening the external terminals, the fixed terminals, and the terminals of the fuse together, and a holding member that holds the stud bolts. The frame includes an attached portion to which the holding member is attached.

First claim

The invention claimed is:

1. An electrical connection box comprising:
a case;
a frame that is made of a resin, a position of the frame being fixed relative to the case;
a fixed terminal that is fixed to the frame and can be connected to an external terminal;
a fuse having a terminal that is put over the fixed terminal;
a fastening member for fastening the external terminal, the fixed terminal, and the terminal of the fuse together; and
a holding member for holding the fastening member, the holding member removably attached to the frame,
wherein the frame includes an attached portion integrally formed to an outer surface of the frame and configured to receive the holding member.

2. The electrical connection box according to claim 1 ,
wherein the holding member includes a locking portion for locking the holding member to the attached portion so that the holding member can move within a range of a predetermined clearance.

3. The electrical connection box according to claim 1 ,
wherein a fitting recessed portion into which at least a portion of an outer face of the fuse is fitted is formed in the holding member.

4. The electrical connection box according to claim 1 ,
wherein an insertion groove portion into which the fastening member is inserted from a direction perpendicular to an axial direction of the fastening member is formed in the holding member.

5. The electrical connection box according to claim 1 , further comprising:
a circuit board on which an electronic component is mounted, the circuit board having a conducting path; and
a fixed bus bar that has the fixed terminal and passes through the frame,
wherein the fixed bus bar is connected to the conducting path of the circuit board.

6. The electrical connection box according to claim 1 ,
wherein the fuse includes a pair of terminals, a blowing portion that is connected between the pair of terminals and blows out when an overcurrent runs therethrough, and an exterior portion covering the blowing portion,
a visual check portion that enables the blowing portion to be visually checked is formed in the exterior portion, and
a visual check hole for exposing the visual check portion is formed in the attached portion to pass therethrough.

7. The electrical connection box according to claim 2 , wherein a fitting recessed portion into which at least a portion of an outer face of the fuse is fitted is formed in the holding member.

8. The electrical connection box according to claim 2 , wherein an insertion groove portion into which the fastening member is inserted from a direction perpendicular to an axial direction of the fastening member is formed in the holding member.

9. The electrical connection box according to claim 3 , wherein an insertion groove portion into which the fastening member is inserted from a direction perpendicular to an axial direction of the fastening member is formed in the holding member.

10. The electrical connection box according to claim 2 , further comprising:
a circuit board on which an electronic component is mounted, the circuit board having a conducting path; and
a fixed bus bar that has the fixed terminal and passes through the frame,
wherein the fixed bus bar is connected to the conducting path of the circuit board.

11. The electrical connection box according to claim 3 , further comprising:
a circuit board on which an electronic component is mounted, the circuit board having a conducting path; and
a fixed bus bar that has the fixed terminal and passes through the frame,
wherein the fixed bus bar is connected to the conducting path of the circuit board.

12. The electrical connection box according to claim 4 , further comprising:
a circuit board on which an electronic component is mounted, the circuit board having a conducting path; and
a fixed bus bar that has the fixed terminal and passes through the frame,
wherein the fixed bus bar is connected to the conducting path of the circuit board.

13. The electrical connection box according to claim 2 ,
wherein the fuse includes a pair of terminals, a blowing portion that is connected between the pair of terminals and blows out when an overcurrent runs therethrough, and an exterior portion covering the blowing portion,
a visual check portion that enables the blowing portion to be visually checked is formed in the exterior portion, and
a visual check hole for exposing the visual check portion is formed in the attached portion to pass therethrough.

14. The electrical connection box according to claim 3 ,
wherein the fuse includes a pair of terminals, a blowing portion that is connected between the pair of terminals and blows out when an overcurrent runs therethrough, and an exterior portion covering the blowing portion,
a visual check portion that enables the blowing portion to be visually checked is formed in the exterior portion, and
a visual check hole for exposing the visual check portion is formed in the attached portion to pass therethrough.

15. The electrical connection box according to claim 4 ,
wherein the fuse includes a pair of terminals, a blowing portion that is connected between the pair of terminals and blows out when an overcurrent runs therethrough, and an exterior portion covering the blowing portion,
a visual check portion that enables the blowing portion to be visually checked is formed in the exterior portion, and
a visual check hole for exposing the visual check portion is formed in the attached portion to pass therethrough.

16. The electrical connection box according to claim 5 ,
wherein the fuse includes a pair of terminals, a blowing portion that is connected between the pair of terminals and blows out when an overcurrent runs therethrough, and an exterior portion covering the blowing portion,
a visual check portion that enables the blowing portion to be visually checked is formed in the exterior portion, and
a visual check hole for exposing the visual check portion is formed in the attached portion to pass therethrough.
