Next, the battery terminal 30 is temporarily assembled with respect to the terminal piece 18 protruding from the fuse box 10. Specifically, as shown in FIG. 8, the mounting bolts 41 are arranged in a slanted posture in which the battery terminal 30 is oriented along the protruding direction of the terminal piece 18 and the clamp portion 31 side is slightly lowered. Is inserted into the mounting hole 19 from below. When the front edge of the upper plate 38 of the support plate 36 hits the lower surface of the terminal piece 18, the rear edge of the upper plate 38 hits the protrusion 44 of the locking piece 43. When the clamp part 31 side of the terminal 30 is pulled up, the locking piece 43 is bent and deformed rearward, and when the upper plate 38 comes into a solid contact state with the lower surface of the terminal piece 18, the rear edge of the upper plate 38 is projected. By passing through 44, the locking piece 43 is restored and deformed, and the protrusion 44 enters and locks on the lower surface side of the rear edge of the upper plate 38. On the other hand, since the upper plate 38 is fitted almost tightly between the side walls 18A of the terminal piece 18, the battery terminal 30 is temporarily attached to the terminal piece 18 in a state in which the battery terminal 30 is prevented from coming off and prevented from rotating. Is done.
Alternatively, the battery terminal 30 may be temporarily assembled to the terminal piece 18 before the fuse device 11 is accommodated in the box 12, and then the fuse device 11 may be accommodated in the box 12.
[0025]
Subsequently, the cover 50 is attached to the fuse box 10. For this purpose, as shown in FIG. 5, the attachment main body 51 of the cover 50 is pushed backward such that the left and right flange portions 60 slide under the left and right flanges 55 in the box 12. When reaching the final stage of pushing, when the side plate 58 is elastically opened and the locked projection 63 gets over the locking projection 62 and is pushed to the normal position, the side plate 58 is restored as shown in FIG. Due to the deformation, the locked protrusion 63 fits behind the locking protrusion 62, and the entire length of the flange 60 extending from the front surface to the left and right side surfaces fits below the flange 55, so that the mounting body 51 is box 12 is attached to the upper end.
At this time, the region extending from the rear edge to the lower edge of the long hanging portion 58 </ b> A of the side plate 58 of the mounting body 51 is substantially flush with the sag preventing wall 65 erected on the side surface of the box 12. The
[0026]
As described above, the fuse box 10 is carried into the attachment site for the battery B with the battery terminal 30 temporarily assembled to the terminal piece 18 and the cover 50 attached in an open state. During the carrying-in or the like, the wire harness or other fuse box pulled out from the fuse box 10 is attached to, for example, the left and right side plates 58 of the mounting body 51 at the portion where the mounting body 51 of the cover 50 is attached to the upper end of the box 12. When 10 or the like hits and lifts up, the locked protrusion 63 on the back surface of the side plate 58 may be disengaged from the locking protrusion 62 on the box 12 side, and the mounting body 51 may be disengaged from the box 12.
In this regard, in this embodiment, the side plate 58 can be easily beaten when a foreign object or the like hits it, but the region extending from the rear edge to the lower edge of the long hanging portion 58A is almost flush with the drooping prevention wall 65. In this case, it is possible to prevent foreign matter or the like from hitting the portion, thereby preventing the side plate 58 from falling, that is, preventing the attachment main body 51 from coming off.
[0027]
At the installation site to the battery B, as shown in FIG. 11, the clamp portion 31 of the battery terminal 30 is inserted into the battery post P in a posture in which the fuse box 10 is arranged on the front side of the battery B (left side in the figure). Then, the clamp portion 31 is fixed to the battery terminal 30 by tightening the nut 34 screwed into the bolt 33 penetrating the pair of projecting pieces 32.
Here, since the fuse box 10 (terminal piece 18) and the battery terminal 30 are temporarily assembled in a non-rotating state, either the fuse box 10 or the battery terminal 30 is tightened during the clamping operation of the clamp portion 31. If you hold down, the orientation of both will be maintained properly.
[0028]
Next, as shown in FIG. 12, the mounting hole 72 of the starter terminal 70 is inserted into the mounting bolt 41 of the battery terminal 30, and the starter terminal 70 is orthogonal to the terminal piece 18 as shown in FIG. 13. Overlaid on top. At this time, the anti-rotation pillar 75 protruding from the resin mold portion 20 covering the base portion of the terminal piece 18 in the fuse device 11 substantially contacts the side edge 70A in the clockwise direction of FIG. It will be in contact.
[0029]
From this state, the nut 77 is screwed onto the tip of the mounting bolt 41 and tightened (clockwise direction in FIG. 13). Thus, the terminal piece 18 and the starter terminal 70 are sandwiched and overlapped between the support plate 36 and the nut 77 of the battery terminal 30, so that the support plate 36 is attached to both sides of the terminal piece 18. The nut 77 is tightened with both the fuse box 10 and the battery terminal 30 positioned by just pressing the fuse box 10 with a light hand because it is fitted between the walls 18A and is prevented from rotating. be able to.
Further, there is a possibility that the starter terminal 70 is rotated by contacting the starter terminal 70 at the final stage of the tightening operation of the nut 77, but when the side edge 70 </ b> A in the clockwise direction immediately hits the non-rotating column 75. That is blocked. Therefore, the nut 77 can be efficiently tightened without loss, and the nut 77 can be held in the normal position without the pressing of the starter terminal 70.
[0030]
When the tightening of the nut 77 is completed as described above, the opening / closing lid 52 of the cover 50 is pivoted and closed so as to take a substantially horizontal posture around the hinge portion 53 as shown in FIGS. Thereby, the periphery of the terminal piece 18 protruding from the battery post P, the battery terminal 30, the starter terminal 70 and the fuse box 10 is covered. In addition, the pair of holding pieces 67 suspended from the ceiling surface of the opening / closing lid 52 are engaged with both side walls 18A on the protruding end side of the terminal piece 18 of the fuse box 10 so that the opening / closing lid 52 is held in a closed state. Is done.
[0031]
In addition, when the opening / closing lid 52 of the cover 50 is closed, if the finger or the like is hung on the operation portion 79 provided on the tip side of the cover 50, the opening / closing lid 52 is moved while forcibly elastically deforming the holding piece 67. Can be opened. After that, for example, if the nut 77 screwed to the mounting bolt 41 is removed, only the starter terminal 70 can be removed, and if the clamp portion 31 of the battery terminal 30 is removed from the battery post P, the battery terminal is connected to the fuse box 10. 30, the starter terminal 70 and the cover 50 can be attached and removed from the battery B.
[0032]
As described above, in the present embodiment, in the portion where the attachment main body 51 of the cover 50 is attached to the upper end portion of the box 12, the locked projection 63 provided on the back surface of the side plate 58 of the attachment main body 51 is 12 is locked by a locking projection 62 provided on the outer side surface of the frame 12, and at this time, a region extending from the rear edge to the lower edge of the long hanging portion 58A of the side plate 58 is outside the box 12. It is in a state of being almost flush with the anti-dripping wall 65 standing on the side.
That is, since the region extending from the rear edge to the lower edge of the long drooping portion 58A where the side plate 58 is likely to be rubbed when a foreign object or the like hits, the portion is surrounded by the drooping prevention wall 65 in a substantially flush manner. As a result, it is possible to prevent the side plate 58 from being bent and, as a result, the attachment main body 51, that is, the cover 50 from being removed.
Further, the side plate 58 of the mounting main body 51 which is prevented from being twisted is positioned outside the lock piece 28 for locking the fuse device 11 from the box 12 so as to prevent the fuse device 11 from coming off, and the bending deformation of the lock piece 28 is inadvertent. Therefore, the lock function for preventing the fuse device 11 from coming off is further strengthened.
