Electrical connection box

1. An electrical connection box comprising:

a bus bar which includes a relief terminal section;

a block which is made of an insulating resin and on which the bus bar is mounted;

a frame which is made of an insulating resin and accommodates the block; and

a terminal cover which covers the relief terminal section, wherein

the block is configured to include a terminal support section which supports the relief terminal section in a state in which the relief terminal section is protruded, and a first cover support section which is provided in the vicinity of the terminal support section,

the frame is configured to include an insertion hole into which the relief terminal section is inserted when the block is accommodated, and a second cover support section which is provided in the vicinity of the insertion hole, and

the terminal cover is rotatably supported around a shaft section of the terminal cover, with the shaft section being interposed between the first cover support section and the second cover support section in an accommodation state in which the block is accommodated in the frame.

2. The electrical connection box according to claim 1 , wherein

the second cover support section is configured to include a semicircular arc section which extends from an edge portion of the insertion hole, is bent to have a semicircular arc shape, and is opened at a side of the first cover support section, and

the shaft section is fitted into the semicircular arc section to allow the terminal cover to be held in the frame.

3. The electrical connection box according to claim 2 , wherein

the terminal support section is formed to have a cantilever plate shape capable of supporting the relief terminal section along one surface of the protruded relief terminal section, and

the first cover support section, which is swollen in an in-plane direction of the relief terminal section, is formed in a base end portion of the terminal support section.

4. The electrical connection box according to claim 2 , wherein a cover protection section is disposed in the vicinity of the relief terminal section and is disposed at a front end side of the relief terminal section rather than the terminal cover which is rotated to a position exposing the relief terminal section.

5. The electrical connection box according to claim 3 , wherein a cover protection section is disposed in the vicinity of the relief terminal section and is disposed at a front end side of the relief terminal section rather than the terminal cover which is rotated to a position exposing the relief terminal section.

6. The electrical connection box according to claim 1 , wherein

the terminal support section is formed to have a cantilever plate shape capable of supporting the relief terminal section along one surface of the protruded relief terminal section, and

the first cover support section, which is swollen in an in-plane direction of the relief terminal section, is formed in a base end portion of the terminal support section.

7. The electrical connection box according to claim 6 , wherein a cover protection section is disposed in the vicinity of the relief terminal section and is disposed at a front end side of the relief terminal section rather than the terminal cover which is rotated to a position exposing the relief terminal section.

8. The electrical connection box according to claim 1 , wherein a cover protection section is disposed in the vicinity of the relief terminal section and is disposed at a front end side of the relief terminal section rather than the terminal cover which is rotated to a position exposing the relief terminal section.
