The mounting part 51 is sandwiched and fixed.

  Further, as shown in FIG. 6, when the bolt 10 is screwed into the nut and the head is fixed with the placement portion 51 between the placement portion 46 and the head, the locking portion 48 protrudes from the placement portion 46. The amount T1 is larger than the protruding amount T2 of the head of the bolt 10. As described above, when the bolt 10 is screwed into the nut and the head is sandwiched and fixed between the mounting portion 46 and the mounting portion 51, the locking portion 48 is further removed from the mounting portion 46 than the head of the bolt 10. Protruding.

  The terminal fitting 11 is in one-to-one correspondence with the terminal fixing portion 12. The terminal fitting 11 is obtained by bending a thick sheet metal. As shown in FIG. 2, the terminal fitting 11 is integrally provided with an electrical contact portion 13 and a wire connection portion 50.

  The electrical contact portion 13 includes a flat plate-like placement portion 51 and a flat plate-like standing portion 52 that are stacked on the placement portion 46. The standing portion 52 is erected from the end of the placement portion 51. A through hole 13a through which the bolt 10 partially screwed into the nut can be passed is provided on the inner side between the placement portion 51 and the standing portion 52. Further, the through hole 13 a extends linearly from the end where the standing portion 52 of the placement portion 51 is erected toward the inside of the placement portion 51. In the electrical contact portion 13, the placement portion 51 is overlapped on the placement portion 46 via the connection piece 30.

  The electric wire connecting portion 50 is bent from the electrical contact portion 13 and is erected from the end farthest from the standing portion 52 of the placement portion 51 of the electrical contact portion 13. In the illustrated example, the angle formed by the wire connecting portion 50 and the electrical contact portion 13 is approximately 90 degrees. Further, the electric wire connecting portion 50 is erected from the end of the placement portion 51 of the electric contact portion 13 described above in the opposite direction to the erected portion 52.

  The electric wire connection part 50 is electrically connected to the electric wire 34 while the electric wire 34 is attached by caulking the electric wire 34.

  In the terminal fitting 11 described above, the electric wire 34 is attached to the electric wire connecting portion 50 and guided by a guide protrusion 53 and a guide groove 54 which will be described later. 22 and 21 are overlapped on the connecting piece 30 and the locking portion 48 enters the through hole 13a, and the locking claw 49 of the locking portion 48 is locked in the through hole 13a.

  Then, the threaded portion of the bolt 10 is inserted into the through hole 13a, and the terminal fitting 11 has the bolt 10 screwed into the nut while the threaded portion of the bolt 10 is in contact with the inner edge of the through hole 13a. The placement portion 51 of the contact portion 13 is sandwiched between the connection piece 30 on the placement portion 46 and the head of the bolt 10 and attached to the terminal fixing portion 12.

  Each terminal fixing portion 12 includes a guide protrusion 53 and a guide groove 54 as shown in FIG. The guide protrusion 53 is formed so as to protrude from the locking portion 48 and is formed in a flat wall shape. The guide groove 54 is provided at the inner edge of the through hole 13a of the electrical contact portion 13 of the terminal fitting 11, and is formed by cutting out the inner edge. The guide groove 54 is formed in a shape that allows the guide protrusion 53 to pass inside and matches the guide protrusion 53. The guide protrusion 53 and the guide groove 54 guide the terminal fitting 11 by the guide protrusion 53 entering the guide groove 54 when the terminal fitting 11 is attached to the terminal fixing portion 12.

  Further, in the two terminal fixing portions 12, the guide protrusion 53 and the guide groove 54 described above are provided at different positions. In the illustrated example, as shown in FIGS. 6 and 7, in the terminal fixing portion 12 on the right side in the drawing, the guide groove 54 and the guide protrusion 53 are arranged on the right side of the center in the width direction of the terminal fitting 11.

The terminal fitting 11 is attached between the two.

  When the electric junction box 1 described above is mounted on an automobile and the automobile travels in a normal state, the side cover 7 is attached to the box body 2 and the closing portion 42 closes the observation hole 19. The position of the closing portion 42 is prevented by the locking receiving portion 44. In addition, the electrical junction box 1 confirms whether or not the side cover 7 is removed from the box body 2 and the fuse 23 in the box body 2 is blown through the observation hole 19 when the automobile is inspected as described above. Is done.

  According to the present embodiment, the locking portion 48 that locks in the through hole 13a of the terminal fitting 11 protrudes from the mounting portion 46 of the mounting portion 45 rather than the bolt 10 as a fastening member. When 48 is locked in the through hole 13a, the terminal fitting 11 is less likely to rattle against the mounting portion 45. Therefore, it is possible to prevent the terminal fitting 11 from rattling when the bolt 10 is fastened (that is, screwed to the nut). Therefore, the bolt 10 can be easily fastened (screwed), that is, the terminal fitting 11 can be easily fixed to the mounting portion 45.

  Further, since the guide protrusion 53 is provided in the locking portion 48 and the guide groove 54 is provided in the inner edge of the through hole 13a, when the terminal fitting 11 is attached to the attachment portion 45, the guide protrusion 53 and the guide groove are provided. 54, the terminal fitting 11 can be guided to the mounting portion 45. For this reason, the terminal fitting 11 can be easily attached to the attachment portion 45. Therefore, the terminal fitting 11 can be easily fixed by the mounting portion 45.

  Furthermore, since the electrical junction box 1 described above includes the terminal fixing portion 12 described above, the terminal fitting 11 can be easily fixed to the mounting portion 45.

  Since the positions of the guide protrusions 53 and the guide grooves 54 of the plurality of terminal fixing portions 12 are different from each other, the terminal fitting 11 can be attached to the mounting portion 45 of the desired terminal fixing portion 12 without error.

  In the above-described embodiment, in order to confirm whether or not the fuse 23 in the box body 2 is blown, the peep hole 19 that makes the inside of the box body 2 visible is provided. However, in the present invention, not only the fuse 23 but also the viewing hole 19 may be used to make the inside of the box body 2 visible for various purposes.
