BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a mounting structure of a fuse puller used for a junction block (electric junction box) which is a component of a wire harness.

[0002]

2. Description of the Related Art Conventionally, for example, a junction block 1 as shown in FIG. 8 is mounted in an engine room of an automobile, and a main body of the junction block 1 or a mounting portion 2 of an upper cover thereof is shown in FIG. A fuse puller 3 like this is installed.
No. 749).

As shown in FIG. 4, the fuse puller 3 generally has a pair of arms 3c, 3c connected to a head 3a and separated by a slit 3b.
Opposed claw portions 3d, 3d are formed inside the free ends of c, 3c, respectively.

As shown in FIGS. 5 to 7, a mounting portion 2 of the junction block 1 has a rectangular frame-shaped first portion.
To the fourth side walls 2a to 2d and the bottom wall 2 of each of the side walls 2a to 2d
e, and a partition wall 2f that partitions the opposing first and third side walls 2a and 2c with a gap t between the bottom wall 2e.

Further, between the first side wall 2a and the partition wall 2f and between the third side wall 2c and the partition wall 2f, the insertion holes 2 of the arm portions 3c, 3c of the fuse puller 3 are provided.
g, 2g are respectively formed on both sides of the lower part of the partition wall 2f. The hooks 3d, 3d of the arm portions 3c, 3c of the fuse puller 3 inserted into the insertion holes 2g, 2g are engaged with each other. Stop portions 2h, 2h are formed respectively.

When the arms 3c, 3c are inserted into the insertion holes 2g, 2g while the slits 3b of the fuse puller 3 are inserted into the partition walls 2f of the mounting portion 2,
After the arms 3c, 3c are deflected outward by the locking portions 2h, 2c, the claws 3d, 3d are locked by the locking portions 2h, 2h.

[0008]

As described above, when the hole 2i is opened in the bottom wall 2e of the fuse puller mounting portion 2, the bottom wall of the mounting portion is required to mount the fuse puller directly to the junction block. When the upper wall of the junction block main body is used, there is a problem that the inside of the junction block main body 1 is flooded. In particular, when the junction block 1 is mounted in the engine room, rainwater or the like easily enters the main body of the junction block 1 through the hole 2i. Since it is necessary to prevent infiltration into the inside of the junction block 1, there is a limitation that the fuse puller 3 must be attached to the waterproof upper cover to avoid attachment to the main body of the junction block 1. .

It is an object of the present invention to provide a fuse puller mounting structure in which a fuse puller can be mounted without making a hole for a molding die in the bottom wall of the mounting portion.

[0010]

In order to achieve the above object, the present invention has a pair of arms connected to a head and separated by a slit, and the inside of the free end of each arm is opposed to each other. The fuse puller on which each claw part is formed,
The mounting portion of the mounting member has a structure in which the mounting portion of the mounting member has first to fourth side walls having a rectangular frame shape, a bottom wall closing a lower end surface surrounded by each side wall, A partition wall for partitioning the first and third side walls with a gap between the first and third side walls, and a gap between the first and third side walls.
An insertion hole for the arm portion of the fuse puller is formed between the third side wall and the partition wall, and the insertion hole between the third side wall and the partition wall is connected to the arm portion of the fuse puller. And a claw portion of an arm portion of a fuse puller inserted into the insertion hole between the first side wall and the partition wall on one side of the lower portion of the partition wall. A locking portion for locking is formed, and a lower hole of the first side wall is provided with a hole of a slide die for forming the locking portion, and the bottom wall is formed from the third side wall to the first side wall.
It is characterized in that it is formed so as to be inclined downward toward the hole in the side wall.

[0011]

According to the fuse puller mounting structure of the present invention,
While inserting the fuse puller slit into the partition wall of the mounting part, insert each arm part into each insertion hole,
After only the arm portion inserted into the wide insertion hole between the first side wall and the partition wall is bent outward by the locking portion, the claw portion is locked by the locking portion. As a result, the fuse puller becomes a single-sided lock instead of the conventional double-sided lock,
The arm portion inserted into the narrow insertion hole between the third side wall and the partition wall is held so that there is no play in the insertion hole. There is no risk of coming off, and no abnormal noise occurs. In addition, since the slide hole for forming the locking portion can be opened at the bottom of the first side wall instead of the bottom wall as in the conventional case, rainwater or the like can be attached to the mounting member (junction block) from the bottom wall. There is no danger of intrusion into the main body. Furthermore, since a slope is formed in the bottom wall of the mounting portion, rainwater or the like that has entered each insertion hole naturally travels along the bottom wall and is quickly discharged to the outside from the hole in the first side wall. There is no possibility that rainwater or the like will accumulate in each insertion hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. 4 and the like, the same components and portions as those of the related art are denoted by the same reference numerals, and detailed description is omitted.

As shown in FIGS. 1 to 3, the mounting portion 5 of the main body of the junction block (mounting member) has first to fourth side walls 5a to 5d in the form of a rectangular frame and the side walls 5a to 5d. A bottom wall 5e for closing the enclosed lower surface,
A gap t between the third side wall 5a, 5c and the bottom wall 5e.
And a partition wall 5f for partitioning the partition wall.

Between the first side wall 5a and the partition wall 5f,
In addition, between the third side wall 5c and the partition wall 5f, the insertion holes 5g, 5 of the arm portions 3c, 3c of the fuse puller 3 are provided.
h are formed respectively. The insertion hole 5g between the first side wall 5a and the partition wall 5f is set widely as in the related art, and the insertion hole 5h between the third side wall 5c and the partition wall 5f is formed as described above. The setting is narrow so that the arm 3c of the fuse puller 3 can be inserted without play.

On one side of the lower part of the partition wall 5f,
The arm portion 3 of the fuse puller 3 inserted into the wide insertion hole 5g between the first side wall 5a and the partition wall 5f.
A locking portion 5i for locking the claw portion 3d of FIG.
The locking portion 5i is formed only on the first side wall 5a side, not on both lower sides of the partition wall 5f as in the related art.

Further, since the locking portion 5i at the lower portion of the partition wall 5f projects outward and is undercut,
As shown in FIG. 2, as the molding die, it is necessary to form the locking portion 5i with the slide die 6 in addition to the normal upper and lower dies. Then, the hole 5j of the slide die 6 for forming the locking portion 5i can be opened.

The bottom wall 5e is formed so as to be inclined downward from the third side wall 5c toward the first side wall 5a.

With the above configuration, when forming the mounting portion 5, in addition to the usual upper and lower dies, the lower locking portion 5i of the partition wall 5f passes through the lower portion of the first side wall 5a. It is molded by a slide mold 6.

While inserting the slit 3b of the fuse puller 3 into the partition wall 5f of the mounting portion 5 formed as described above, the arm portions 3c, 3c are inserted into the insertion holes 5g, 5h, respectively. After only the arm 3c inserted into the wide insertion hole 5g between the first side wall 5a and the partition wall 5f is bent outward by the locking portion 5i, as shown in FIG.

The arm 3c inserted into the narrow insertion hole 5h between the side wall 5c and the partition wall 5f is held in the insertion hole 5h without rattling. There is no possibility that the claw portion 3d comes off the locking portion 5i, and no abnormal noise due to rattling occurs.

Further, the hole 5j of the slide die 6 for forming the locking portion 5i of the mounting portion 5 is provided with the bottom wall 5 as in the prior art.
Since it can be opened at the lower part of the first side wall 5a instead of e, there is no possibility that rainwater or the like will enter the main body of the junction block from the bottom wall 5e.

Further, since a gradient is formed on the bottom wall 5e of the mounting portion 5, rainwater or the like that has entered the insertion holes 5g, 5h naturally travels along the bottom wall 5e to remove the first side wall 5a. Since the water is quickly discharged from the hole 5j to the outside, there is no possibility that rainwater or the like accumulates in the insertion holes 5g and 5h.

[0023]

[Effect of the Invention] As is clear from the above description, the mounting structure of the fuse puller of the present invention is such that only the claw portion of the arm portion of the fuse puller inserted into the wide insertion hole of the mounting portion is the locking portion. The arm part is locked so that there is no backlash, so there is no danger of the lock coming off even if it receives vibration or impact, and no abnormal noise is generated. . In addition, since the hole of the slide die for forming the locking portion can be opened in the lower portion of the first side wall, there is no possibility that rainwater or the like enters the mounting member from the bottom wall. Furthermore, since a slope is formed on the bottom wall of the mounting portion, rainwater or the like that has entered each insertion hole naturally travels along the bottom wall and is quickly discharged to the outside through the hole in the first side wall. There is no possibility that rainwater or the like will accumulate in the insertion hole.
