As shown in FIGS. 1 and 2, locking projections 1 a ₁ are respectively formed on a pair of opposed side plates 1 a, 1 a of the storage box 1, and flexible locking pieces 2 a formed on the pair of side plates of the cover 2. And locking means. A notch 2b for accommodating an insulating guide 1c described later is formed on one side plate in the longitudinal direction of the cover 2.

The storage box 1 has three partition walls 1 in the longitudinal direction.
b ₁ , 1b _2, and 1b ₃ are formed, and a terminal accommodating chamber 3a is provided which is partitioned by a partition wall 3 in a direction intersecting the partition. The partition walls 1b ₁ and 1b are provided in the terminal accommodating chamber 3a.
_{3 A} flexible locking piece 3b protrudes from the inner side toward the center partition wall 1b in the direction of ₂ to form terminals 4a, 4b, and 4c of terminals 4a, 4b, and 4c formed on a connection terminal 4 made of a metal plate.
The locking holes 4d formed in the holes a and 4c and locking means are formed to prevent back-out.

The connecting portion 4e of the connecting terminal 4 is formed with holed terminals 4f and 4g which are lifted up at different levels.
Step T ₁ between the inner surface of the perforated terminal 4f and the outer surface of the perforated terminal 4g.
, Together with the perforated pin 4f is lifted by the thickness T ₀ min perforated terminals 5a of the brazed-terminal 5 to be described later, between the nut ₇₁ to be described later perforated terminal 4f, substantially Anazuke terminal 5a A space S corresponding to the thickness of the fusible link 6 and the contact piece 6a with a hole is provided (see FIGS. 3, 4 and 5).

The terminals 4a, 4 inserted into the terminal accommodating chamber 3a
b and 4c constitute contact means for contacting a contact piece 6a 'of a fusible link 6' (not shown) inserted from above the storage box 1. Together with the nut ₇₁ partially cut out of the partition walls 1b ₁ is inserted, perforated terminal connected to the perforated terminal 5a of the straight With terminal 5 terminal 4 when assembling the fusible link device A finally constitute the screwing means and 4f with bolts 8 _1.

[0016] Similarly, with the nut 7 ₂ notched part of the partition wall 1b ₁ is inserted, connected to the perforated terminal 5c straight with terminal 5 when assembling the fusible link device A finally It constitutes a threaded section and a perforated terminal 4g of the terminal 4 by bolts _82.

The other connecting terminal 4 ₁ (not shown) is similarly inserted into the terminal accommodating chamber 3 a formed between the partition walls 1 b ₂ and 1 b _3, and the terminals 4 a ₁ and 4 b (not shown) are also inserted.
_1, and 4c ₁ constitute the contact means with the 'other contact piece 6b of the' fusible link 6 is inserted from above the storage box 1.

The terminal 5 made of a metal plate has terminals 5a, 5b and 5c formed at its ends, and the substrate 5d extends along a gutter-shaped insulating guide 1c protruding from the storage box 1. And one end 5b is bent at a corner 5e at a step, and the corner 5e is bent at a right angle to a gutter-shaped insulating guide 1c protruding from the storage box _1. (See FIG. 3).

The perforated terminal 5b constitutes a connection means to be screwed to the battery terminal. Since the first embodiment is configured as described above, the storage box 1 is first used during use.
The nut 7 is inserted into a part of the partition wall 2a where a part is cut out. Then, while maintaining a state where the substrate portion 5d and along a dielectric guide 1c of storage box 1 butted corners 5e straight with terminal 5 at the corner portion 1c ₁ of the insulating guide 1c straight with terminal 5, connection terminal 4a of the terminal 4, 4b, and when inserted 4c to the corresponding housing chamber 3a, the resilient locking pieces 3b which projects from the partition wall 1b ₁ inside each housing chamber 3a tip of the terminals 4a and 4c The locking hole 4d is locked. At this time, the terminal 5 with the hole
c is located above the perforated terminal 4g of the connection terminal 4, and the perforated terminal 5a is
Since it is located below f, the directly-attached terminal 5 is engaged with the connection terminal 4 and is held in a temporarily locked state.

Next, the cover 2 is mounted on the storage box 1 from above the storage box 1, and the locking projections 1 of the storage box 1 are fixed by the flexible locking pieces 2a.
engaged in a _1, it may be delivered to the final assembly site.
Therefore, since the storage box 1 and the directly attached terminal 5 are distributed as a set, not only the management is easy, but also the effect of reducing the number of man-hours for final assembly is obtained.

FIG. 6 is a perspective view of a main part of a second embodiment according to the present invention. In FIG. 6, an insulating guide 1c 'is a gutter-shaped insulating guide 1c' similar to that of the first embodiment protruding from a storage box 1 '(not shown), and a pair of side plates 1c ₂ of the insulating guide 1c'. ', 1c _2' from the edge of the 'pair more storage box 1' corners 1c ₁ toward the inward locking projection 1c ₃ 'of the pair of wedge shape from being formed.

The other configuration is the same as that of the first embodiment, and the description is omitted. However, there is no need to engage the not-shown directly connected terminal 5 'with the not-shown connecting terminal 4', so the connecting terminal 4 'is not provided with a step in the first embodiment.

Since the second embodiment is constructed as described above, the terminals 4a ', 4b', and 4c 'of the connecting terminal 4' are connected to the corresponding accommodation chambers 3a 'when used, as in the first embodiment. Insert Next, the substrate 5d 'of the directly-attached terminal 5' is aligned with the insulating guide 1c ', and the corner 5e' of the directly-attached terminal 5 'is turned into the corner 1
Slide until it hits c ₁ ′. At this time, since the side plate 1c ₂ ′ on which the locking projection 1c ₃ ′ is projected is flexible, the rising portion of the corner 5e ′ of the directly-mounted terminal 5 ′ passes over the locking projection 1c ₃ ′. 'together abuts against the rear dropout is engaging projection 1c _3' corners 1c ₁ is blocked, the direct mounting terminals 5 'are locked provisionally.

The effects are the same as in the first embodiment. In the first embodiment according to the present invention, by providing a step T ₁ between the perforated terminals 4f and Anazuke terminal 4g of the connecting terminal 4, as is straight with terminal 5 engages the connecting terminal 4 The terminal 4g with a hole of the connecting terminal 4
The terminal 4b is formed in a U-shape inward from the lower edge of the connection terminal 4, and a hole for a bolt is formed in the lower portion.
May be configured to engage with the connection terminal 4 and temporarily locked.

[0025]

[Effect of the Invention] The present invention is configured as described above.
Since the direct-attached terminal can be temporarily locked to the storage box without bolts, the storage box and the direct-attached terminal are distributed as a set, so that they are easy to manage and have the effect of reducing the number of final assembly steps. .
