Although not shown, the housing 20 is provided with a holding mechanism for holding the assembled first housing member 21 and the second housing member 22 in that state. As the holding mechanism, for example, a so-called lock mechanism may be used in which the assembled first housing member 21 and the second housing member 22 are locked by a claw or the like so as not to be separated from each other.

Here, the electrical connection box 1 is provided with a holding mechanism 30 for holding the electronic component 10 housed in the storage chamber 20a in the storage chamber 20a (FIGS. 1, FIG. 2, FIG. 4, FIG. 6 and FIG. 7). Two holding mechanisms 30 are provided for each electronic component 10 (for each accommodation chamber 20a).

The holding mechanism 30 includes a locking body 31 provided on the first housing member 21 and a locked body 32 provided on the electronic component 10 (FIGS. 1, 2 and 4). The holding mechanism 30 locks the locking portion 31a of the locking body 31 and the locked portion 32a of the locked body 32 with each other in the insertion / removal direction of the electronic component 10 with respect to the accommodating chamber 20a, thereby engaging the electronic component. 10 is held in the storage chamber 20a (FIG. 4).

At least one of the locking portion 31a and the locked portion 32a is formed as a protrusion such as a claw, and the electronic component 10 is locked by locking the protrusion to the other party. It is held in the containment chamber 20a. Here, the protrusion is provided on the electronic component 10. In the electronic component 10, one locked body 32 is provided on each of the first outer wall body 11a and the second outer wall body 11b that are arranged to face each other. In the electronic component 10 of this example, the locked body 32 is a protrusion, and the locked body 32 itself is the locked portion 32a of the first outer wall body 11a and the second outer wall body 11b. The locked body 32 is projected from each outer wall surface (FIGS. 1, 2 and 5). The locked bodies 32 are arranged so as to face each other in the direction along the facing arrangement direction of the first outer wall body 11a and the second outer wall body 11b.

The locking body 31 is formed as having the following flexibility. The locking body 31 is pushed by the locked portion 32a (locked body 32) in the process of inserting the electronic component 10 into the accommodating chamber 20a and bends, and when the electronic component 10 is accommodated in the accommodating chamber 20a. The flexibility is eliminated so that the locking portion 31a can be arranged to face the locked portion 32a (locked body 32) on the side in the removal direction of the electronic component 10 from the accommodation chamber 20a. have. When the locking body 31 is pushed by the locked portion 32a (locked body 32), the locking body 31 is bent to the opposite side of the storage chamber 20a.

One locking body 31 is provided in each of the first standing wall body 21b and the second standing wall body 21c which are arranged to face each other in each of the accommodation chambers 20a (FIGS. 1, 6 and 7). Further, the locking bodies 31 of the first standing wall body 21b and the second standing wall body 21c are spaced apart from each other in the direction along the facing arrangement direction of the first standing wall body 21b and the second standing wall body 21c for each accommodation chamber 20a. Are placed facing each other with a space (FIGS. 1, 6 and 7). Further, the locking bodies 31 of the first standing wall body 21b of one storage chamber 20a and the second standing wall body 21c of the other storage chamber 20a are arranged adjacent to each other in the adjacent arrangement direction of the two storage chambers 20a arranged adjacent to each other. They are arranged so as to face each other with a gap between them (FIGS. 1, 6 and 7).

Here, the locking body 31 provided in the first standing wall body 21b of one of the accommodation chambers 20a is referred to as the first locking body 31A, and the locking body provided in the second standing wall body 21c of the other accommodation chamber 20a is referred to. 31 may be referred to as a second locking body 31B (FIGS. 1, 6 and 7). When the first locking body 31A and the second locking body 31B are pushed by the locked portion 32a (locked body 32), the first locking body 31A and the second locking body 31B are opposite to the storage chamber 20a (toward the gap between them). Bend it.

The locking body 31 of this example is erected from the bottom wall body 21a side toward the rising direction of the locking portion 31a and the first standing wall body 21b (second standing wall body 21c), and with respect to the rising direction. Among the orthogonal directions, there are two standing portions 31b arranged so as to face each other at intervals in the direction along the plane of the first standing wall body 21b (second standing wall body 21c) (FIGS. 1, FIG. 2, FIG. 4, FIG. 6 and FIG. 7). In the locking body 31, the ends of the two standing portions 31b in the rising direction are connected to each other by the locking portion 31a, and each of the standing portions 31b is made flexible as described above. For example, the locking portion 31a is formed in a rectangular flat plate shape, and the locked portion 32a (locked body 32) is locked to one side portion between the two standing portions 31b.

The locking portions 31a of the first standing wall body 21b and the second standing wall body 21c are spaced apart from each other in the direction along the facing arrangement direction of the first standing wall body 21b and the second standing wall body 21c for each accommodation chamber 20a. They are arranged to face each other (FIGS. 1, 6 and 7). Further, the locking portions 31a of the first standing wall body 21b of one storage chamber 20a and the second standing wall body 21c of the other storage chamber 20a (the respective engaging portions of the first locking body 31A and the second locking body 31B). The stopping portions 31a) are arranged so as to face each other with a gap in the adjacent arrangement direction of the two storage chambers 20a arranged adjacent to each other (FIGS. 1, 6 and 7).

In the holding mechanism 30, as the electronic component 10 is inserted from the insertion port 20a ₁ , the locked portion 32a (locked body 32) comes into contact with the locking portion 31a of the locking body 31. Each of the locking portions 31a of the first standing wall body 21b and the second standing wall body 21c may be provided with an inclined surface on the contact surface with the locked portion 32a (locked body 32) for each accommodation chamber 20a. Good. Their respective inclined surfaces of the opposite arrangement is formed as an interval in the opposed direction, and increases toward its insertion opening 20a ₁ side.

In the holding mechanism 30, as the insertion of the electronic component 10 progresses, the locked portion 32a (locked body 32) pushes the locking portion 31a to the opposite side of the storage chamber 20a while pushing the locking portion 31a. Each standing portion 31b is bent. In the holding mechanism 30, when the electronic component 10 is further inserted and the electronic component 10 is accommodated in the accommodating chamber 20a, the bending of each of the standing portions 31b is eliminated, and the electronic component 10 is locked with the locking portion 31a. The portion 32a (locked body 32) is arranged to face the electronic component 10 in the insertion / removal direction with respect to the accommodation chamber 20a. Here, the locking portion 31a is arranged to face the locked portion 32a (locked body 32) on the side in the removal direction of the electronic component 10 from the accommodation chamber 20a (FIG. 4).

In the holding mechanism 30, when the electronic component 10 is pulled out from the storage chamber 20a, each of the holding mechanisms 30 is directed in the pushing direction by the locked portion 32a (locked body 32) when the electronic component 10 is inserted. The standing portion 31b is bent. In this holding mechanism 30, when the locking portion 31a and the locked portion 32a (locked body 32) are in a facing arrangement state, the locking body 31 is bent to bend the locking portion 31a and the locked portion 31a and the locked portion 32a. The electronic component 10 can be pulled out from the storage chamber 20a by tilting the locking portion 31a and the respective standing portions 31b until the facing arrangement state of the 32a (locked body 32) is eliminated.

In the electrical connection box 1, the first housing member 21 and the second housing member 22 are assembled after the electronic components 10 are housed in the respective storage chambers 20a. The electrical connection box 1 uses the following jigs when performing these assembly operations.

The first housing member 21 and the second housing member 22 each have positioning holes 25a and 26a into which positioning pins 101 (FIG. 1) for assembling each other are inserted (FIGS. 1, 2 and 2). 4). In the electrical connection box 1, for example, the positioning pin 101 is inserted into the positioning hole 25a to determine the position of the first housing member 21 on the jig plate (not shown). The positioning pin 101 is projected from the positioning hole 25a. Then, in the electrical connection box 1, the electronic components 10 are housed in the respective storage chambers 20a. After that, in the electrical connection box 1, the second housing member 22 is assembled to the first housing member 21 while inserting the positioning pin 101 protruding from the positioning hole 25a into the positioning hole 26a.

The electric junction box 1 assembled in this way is attached to the vehicle body or the like. Therefore, external inputs such as road surface input during traveling and vibration of the drive source act on the electric junction box 1 via the vehicle body, and acceleration / deceleration and lateral acceleration during traveling act as external inputs. .. The external input also acts on the electronic component 10 and the holding mechanism 30. Therefore, the electrical connection box 1 is configured to be able to maintain the holding function of the holding mechanism 30 regardless of the presence or absence of an external input.

Specifically, in the electrical connection box 1, when the assembly of the first housing member 21 and the second housing member 22 is completed, the bending of the locking body 31 of the holding mechanism 30 is regulated. The holding function of the holding mechanism 30 is maintained. In the electrical connection box 1, the locking portion 31a and the locked portion 32a (locked body 32) are arranged to face each other at the assembled position of the first housing member 21 and the second housing member 22. The amount of deflection of the locking body 31 is regulated within a range in which the above can be maintained. Here, a restricting body 26 for performing such regulation is provided on the second housing member 22 (FIGS. 1, 2 and 4).

The regulating body 26 is provided to regulate the amount of bending of at least one of the two holding mechanisms 30 provided for each accommodation chamber 20a. That is, as long as the holding function of the holding mechanism 30 can be maintained, the regulating body 26 may be provided to regulate the amount of bending of only one of the two holding mechanisms 30, the locking body 31. Each holding mechanism 30 may be provided to regulate the amount of bending of both locking bodies 31 of the two holding mechanisms 30.

The restricting body 26 is formed as a protruding body that protrudes inside the second housing member 22 in the assembling direction of the second housing member 22 to the first housing member 21. The restricting body 26 is, for example, up to a position where the first housing member 21 and the second housing member 22 are arranged to face the locking portion 31a of the locking body 31 at the assembly completion position, or the assembly is completed. At the position, the locking body 31 is extended to a position facing the standing portion 31b. The restricting body 26 is erected with a locking portion 31a when the electronic component 10 is pulled out from the accommodation chamber 20a when the assembly of the first housing member 21 and the second housing member 22 is completed. The portion 31b is arranged to face the locking portion 31a or the upright portion 31b on the tilting direction side. Therefore, it is assumed that the restricting body 26 is about to be bent by an external input or the like so that the locking portion 31a and the locked portion 32a (locked body 32) are in a state of being opposed to each other. Also, the locking portion 31a or the standing portion 31b is locked on the outer wall surface thereof, and the locking portion 31a and the locked portion 32a (locked body 32) are engaged within a range that can be maintained in a facing arrangement state. The amount of bending of the stop body 31 can be regulated. Therefore, in the electrical connection box 1, when the assembly of the first housing member 21 and the second housing member 22 is completed, the holding function 30 provides the holding function of the electronic component 10 in the storage chamber 20a. Can continue to be maintained.

The restricting body 26 is formed as, for example, a tubular body having a protruding direction as a tubular axial direction. Here, the space inside the tubular regulator 26 is used as the positioning hole 26a. That is, the positioning hole 26a of the second housing member 22 may be formed in the regulating body 26. Therefore, in the electrical connection box 1, the positioning hole 26a and the regulator 26 can be shared, and it is not necessary to separately prepare the regulator 26. Therefore, the physique can be downsized and the productivity can be improved. Can be done.

In the case of sharing the positioning hole 26a with the regulator 26, the positioning hole 25a of the first housing member 21 is also locked with the locking portion 31a when the electronic component 10 is pulled out from the accommodation chamber 20a. Is arranged on the tilting direction side of the upright portion 31b. Therefore, the positioning hole 25a hinders the bending of the locking body 31 during the work so as not to interfere with the work of accommodating the electronic component 10 in the accommodating chamber 20a and the operation of extracting the electronic component 10 from the accommodating chamber 20a. Place it in a position that does not. For example, the positioning hole 25a is provided inside the cylinder. In the first housing member 21 of this example, a cylindrical body 25 is formed in which the inner space is a positioning hole 25a (FIGS. 1, 6 and 7). The cylindrical body 25 may be arranged at a position where it does not come into contact with the bent locking body 31. For example, the cylindrical body 25 is arranged so as to enter between the respective standing portions 31b when the locking body 31 bends.

Here, the restricting body 26 is arranged to face the locking portion 31a, and the locking portion 31a is locked to the outer wall surface of the restricting body 26. Further, here, the restricting body 26 is formed in a cylindrical shape, and the locking portion 31a is locked on the outer peripheral surface thereof.

Here, between the two adjacent storage chambers 20a, the amount of deflection of the locking body 31 of each of the two adjacent holding mechanisms 30 may be regulated by the common regulating body 26. In this example, the restricting body 26 is arranged in the gap between the two adjacent locking bodies 31 (the first locking body 31A and the second locking body 31B), and the common restricting body 26 engages with each other. By regulating the amount of bending of the stop body 31, the electronic components 10 housed in the respective storage chambers 20a are maintained in the housed state. Here, the positioning hole 26a is provided in the common regulator 26.

The second housing member 22 of this example has a regulating body 26 arranged in a gap between the first locking body 31A and the second locking body 31B at the position where the assembly with the first housing member 21 is completed. Has (FIGS. 1, 2 and 4). Here, one regulator 26 is provided on the second housing member 22. The restricting body 26 regulates the amount of bending of the first locking body 31A within a range in which the locking portion 31a and the locked portion 32a (locked body 32) can be kept facing each other, and is locked. The bending amount of the second locking body 31B can be regulated within a range in which the portion 31a and the locked portion 32a (locked body 32) can be kept facing each other.

When the assembly of the first housing member 21 and the second housing member 22 is completed, the restricting body 26 has the locking portions 31a of the first locking body 31A and the second locking body 31B, respectively. It extends in the protruding direction to a position facing each of the locking portions 31a. That is, the restricting body 26 is the first section when the electronic components 10 are taken out from the respective storage chambers 20a when the assembly of the first housing member 21 and the second housing member 22 is completed. On the tilting direction side of the stop body 31A and the second locking body 31B, the first locking body 31A and the second locking body 31B are arranged to face each other of the locking portions 31a. Therefore, the restricting body 26 is bent so as to eliminate the facing arrangement state of the locking portion 31a and the locked portion 32a (locked body 32) due to an external input or the like, and the first locking body 31A (second). Even if it is about to occur in the locking body 31B), the locking portion 31a is locked on the outer wall surface thereof, and the locked portion 31a and the locked portion 32a (locked body 32) are kept facing each other. The amount of deflection of the first locking body 31A (second locking body 31B) can be regulated within the obtained range. Therefore, in the electrical connection box 1, when the assembly of the first housing member 21 and the second housing member 22 is completed, the holding function 30 provides the holding function of the electronic component 10 in the storage chamber 20a. Can continue to be maintained.

Therefore, in the electrical connection box 1, the electronic component 10 can be extracted from the storage chamber 20a.

As shown above, in the electrical connection box 1 of the present embodiment, when the assembly of the first housing member 21 and the second housing member 22 is completed by the restricting body 26, the electrons by the holding mechanism 30 are used. The holding function of the component 10 in the storage chamber 20a can be maintained. Since the effect of the electrical connection box 1 can be obtained only by assembling the first housing member 21 and the second housing member 22, it is possible to suppress an increase in assembling man-hours. In particular, in the electrical connection box 1 illustrated above, since the regulating body 26 is provided with the positioning hole 26a, the first housing member 21 and the second housing member 21 and the second housing member 21 and the second housing member 21 do not need to be aware of the arrangement of the regulating body 26 after the assembly is completed. The assembling work is completed only by assembling the housing member 22. Therefore, the electrical connection box 1 can maintain the holding function by the holding mechanism 30 without deteriorating the assembling workability.

Further, in the electric connection box 1 of the present embodiment, the restricting body 26 is removed from the gap between the first locking body 31A and the second locking body 31B only by removing the second housing member 22 from the first housing member 21. Can be pulled out. That is, in this electrical connection box 1, the second housing member 22 is removed from the first housing member 21, and the first locking body 31A (second locking body 31B) and the locking body paired thereto The electronic component 10 can be pulled out from the storage chamber 20a simply by bending the 31. Therefore, the electrical connection box 1 can also suppress a decrease in maintenance workability.

By the way, in the electrical connection box 1 of the present embodiment, the regulator 26 is fitted into the positioning hole 25a of the first housing member 21 at the position where the assembly of the first housing member 21 and the second housing member 22 is completed. It may be (Fig. 11). On the contrary, in the electrical connection box 1 of the present embodiment, the cylindrical body 25 is the second housing member 22 at the position where the first housing member 21 and the second housing member 22 are assembled. It may be fitted into the positioning hole 26a. As a result, when the assembly of the first housing member 21 and the second housing member 22 is completed, the electrical connection box 1 becomes the first housing member 21 and the second housing member 22. It is possible to suppress rattling between. In this example, the restricting body 26 is fitted inside the cylindrical body 25. Here, the cylindrical body 25 takes into consideration the tolerance variation between the first housing member 21 and the second housing member 22 and the assembly variation between the first housing member 21 and the second housing member 22. It is desirable to form the tip in the tubular axis direction so that it does not come into contact with the regulator 26. Similarly, the restricting body 26 takes into consideration the tolerance variation between the first housing member 21 and the second housing member 22 and the assembly variation between the first housing member 21 and the second housing member 22. Therefore, it is desirable to form the tip so that the tip in the tubular axis direction does not come into contact with the cylindrical body 25. As a result, in the electrical connection box 1, when the first housing member 21 and the second housing member 22 are assembled, the cylindrical body 25 and the restricting body 26 are not caught in the cylindrical axial direction.
