Further, the electrical connection box 1 includes a conductive fastening object 50 housed in the housing member 20 (FIGS. 1 to 8). The temporary holding mechanism 30A is composed of the accommodating member 20 and the fastening object 50. The electrical connection box 1 includes a fastening structure 60 in which the fastening object 50 is fastened by the female screw member 10 and the male screw member 40 in the housing member 20 (FIGS. 1 to 8). The fastening structure 60 is composed of a fastening object 50, a female screw member 10, a male screw member 40, and a female screw fixing structure 30.

The female screw member 10 has a female screw portion 11 into which the male screw portion 41 of the male screw member 40 is screwed (FIGS. 1, FIG. 3, FIG. 6, FIG. 7, FIG. 9, and FIG. 10). The female screw portion 11 is formed in a cylindrical shape, and a female screw is screwed on the inner peripheral surface thereof. Further, the male screw portion 41 is alerted to a columnar shape, and a male screw is engraved on the outer peripheral surface thereof.

Further, the female screw member 10 is provided on one end side of the female screw portion 11 in the screw axial direction, and when the male screw member 40 is in the screwing completed state, the object to be fastened with the male screw member 40 is 50.

Here, in this example, as the fastening object 50, the plate-shaped connecting portion 51 of the conductive member 70 and the plate-shaped electronic component 80 housed in the component storage chamber 21 (FIGS. 1 and 2) of the housing member 20. The terminal portion 52 of the above is provided (FIGS. 1 and 3 to 6). The conductive member 70 shown here is a so-called bus bar formed into a plate shape from a conductive material such as metal. The connecting portion 51 is formed in a flat plate shape. A circular through hole 51a through which the male screw portion 41 is inserted is formed in the connecting portion 51 (FIGS. 1, 11 and 12). On the other hand, the electronic component 80 may be any kind as long as it includes a plate-shaped terminal portion 52 and the terminal portion 52 is arranged so as to protrude from the main body 81 ( Figure 1). The terminal portion 52 is formed in a single body shape such as a male tab terminal or the like. The terminal portion 52 is formed with a circular through hole 52a through which the male screw portion 41 is inserted (FIG. 1). In the electronic component 80, the main body 81 is accommodated in the component accommodating chamber 21, and the terminal portion 52 is projected outward from the component accommodating chamber 21.

The terminal portion 52 of this example is inserted between the sandwiching portion 12 of the female screw member 10 and the connecting portion 51 of the conductive member 70 (FIGS. 3 and 6). When the insertion of the terminal portion 52 is completed, one plane is brought into surface contact with the holding portion 12, and the other plane is brought into surface contact with one plane of the connecting portion 51. For example, here, the fuse is shown as an example of the electronic component 80. In the accommodating member 20, the female screw member 10 and the conductive member 70 are accommodated in advance (FIG. 5), and by accommodating the electronic component 80 in the component accommodating chamber 21, the terminal portion 52 becomes the female screw member 10. It is inserted between the sandwiching portion 12 of the above and the connecting portion 51 of the conductive member 70 (FIGS. 3, 4 and 6). In the accommodating member 20, when the connecting portion 51 of the female screw member 10 and the conductive member 70 and the terminal portion 52 of the electronic component 80 are in the accommodating state, they are connected substantially coaxially with the screw shaft of the female screw member 10. A through hole 51a of the portion 51 and a through hole 52a of the terminal portion 52 are arranged. However, as will be described later, the female screw member 10 can move relative to the accommodating member 20, so that the screw shaft is eccentric with respect to the centers of the through holes 51a and 52a within the range of the relative movement amount. In some cases.

By the way, the electronic component 80 of this example is provided with two terminal portions 52 (FIGS. 1 and 3 to 5). Then, in the electric connection box 1 of this example, a female screw member 10 and a conductive member 70 corresponding to each terminal portion 52 are provided. Therefore, the electrical connection box 1 of this example is provided with two sets of a combination of a connecting portion 51 and a terminal portion 52 fastened by the female screw member 10 and the male screw member 40 (FIGS. 3 to 5). In other words, in this exemplary accommodating member 20, two sets of combinations of the female screw member 10 forming the fastened state, the male screw member 40, the connecting portion 51, and the terminal portion 52 are accommodated (FIGS. 3 to 5). ). Regarding each connecting portion 51, one of them is held by one conductive member 70 (conductive member 70A), and the other of them is held by the other conductive member 70 (conductive member 70B) (conducting member 70B). 3 to 5, FIGS. 11 and 12).

Returning to the female screw member 10, the female screw member 10 is further arranged on the outer side of the female screw portion 11 on the other end side in the screw axial direction at a flange portion 13 orthogonal to the screw axial direction. (FIGS. 1 and 3 to 10). The flange portion 13 is one of the first wall portions in the screw axis direction (that is, the first wall portion arranged on the sandwiching portion 12 side in the screw axis direction) 13a (FIGS. 3, 6, 7, and 9). ) And the other second wall portion in the screw axis direction (that is, the second wall portion arranged on the side opposite to the holding portion 12 side in the screw axis direction) 13b (FIGS. 3, 6, 7, and 7). 10) and. Further, the flange portion 13 has a first locked portion 13c and a second locked portion 13d (FIGS. 3 and 7) at both ends of the first orthogonal direction Go1 (FIGS. 1 to 3) orthogonal to the screw axis direction. 10) and the third locked portion 13e and the fourth locked portion 13e at both ends of the second orthogonal direction Go2 (FIGS. 1, 2 and 4) orthogonal to the screw axis direction and the first orthogonal direction Go1. It has 13f (FIGS. 6 and 8 to 10).

Here, the first orthogonal direction Go1 is a direction orthogonal to the insertion direction when the female screw member 10 is accommodated in the accommodating member 20 and a direction opposite to the insertion direction (for example, the female screw member 10 is accommodated in the accommodating member 20). The direction orthogonal to the removal direction when removing from 20) is shown (FIGS. 1 and 2). Therefore, the second orthogonal direction Go2 refers to the insertion direction when the female screw member 10 is accommodated in the accommodating member 20 and the direction opposite to the insertion direction.

The flange portion 13 of this example is formed in a flat plate shape having a substantially rectangular outer circumference (FIGS. 1, 9 and 10). Therefore, in the flange portion 13 of this example, one plane is the first wall portion 13a and the other plane is the second wall portion 13b. Further, in the flange portion 13 of this example, one side portion in the first orthogonal direction Go1 is the first locked portion 13c, and the other side portion in the first orthogonal direction Go1 is the second locked portion 13d. Become. Further, in the flange portion 13 of this example, one side portion in the second orthogonal direction Go2 becomes the third locked portion 13e, and the other side portion in the second orthogonal direction Go2 becomes the fourth locked portion 13f. Become.

The female screw member 10 of this example has a chamfered portion in which the outer circumference of the flange portion 13 is square and each corner portion of the flange portion 13 is inclined by 45 degrees with respect to each side portion. Therefore, the same outer shape is formed at all the positions rotated by 90 degrees around the axis of the screw shaft. Therefore, in the female screw member 10 of this example, any one of the four side portions of the flange portion 13 can be an insertion starting point into the accommodating member 20. Therefore, in the female screw member 10 of this example, the side portion of the flange portion 13 serving as the insertion starting point into the accommodating member 20 is set as the third locked portion 13e, and the third locked portion 13e is used as a reference. The first locked portion 13c, the second locked portion 13d, and the fourth locked portion 13f on the remaining three sides of the collar portion 13 are defined. Therefore, the first locked portion 13c is provided at one end on one side in the first orthogonal direction Go1 at the flange portion 13 at the accommodation completion position in the accommodation member 20. The second locked portion 13d is provided at the other end of the other side in the first orthogonal direction Go1 at the flange portion 13 at the accommodation completion position in the accommodation member 20. Further, the third locked portion 13e is provided at one end of the flange portion 13 at the accommodation completion position of the accommodation member 20 on one side in the second orthogonal direction Go2. The fourth locked portion 13f is provided at the other end of the other side in the second orthogonal direction Go2 at the flange portion 13 at the accommodation completion position in the accommodation member 20. In the flange portion 13 of this example, each of the four corners is chamfered.

The accommodating member 20 is formed of an insulating material such as synthetic resin. The accommodating member 20 may be formed into a box shape such as a housing, or may be formed as a so-called block that is accommodated and held in the housing. .. Here, the accommodating member 20 formed as a block is illustrated.

In the accommodating member 20, the component accommodating chamber 21 shown above is formed. The electronic component 80 is inserted into the component accommodating chamber 21 from the two terminal portions 52 side through the opening (electronic component insertion port) 21a (FIGS. 1 and 2). In the electronic component 80, two terminal portions 52 are projected from the main body 81 in the insertion direction thereof. Therefore, in the accommodating member 20, when the main body 81 is in the accommodating completed position with respect to the component accommodating chamber 21, the two terminal portions 52 are projected to the outside of the component accommodating chamber 21. The accommodating member 20 includes a terminal accommodating chamber 22 in which a terminal portion 52 projecting outward from the component accommodating chamber 21 is accommodated (FIGS. 1 to 8).

The terminal accommodating chamber 22 also accommodates the female screw member 10 and the connecting portion 51. Therefore, the terminal accommodating chamber 22 can be rephrased as a female screw accommodating chamber. The terminal accommodating chamber 22 is provided for each combination of the female screw member 10, the male screw member 40, the connecting portion 51, and the terminal portion 52 (FIGS. 3 to 5 and 7). The terminal accommodating chambers 22 are arranged side by side along the screw axis direction. The terminal accommodating chamber 22 has an opening 22a on the side opposite to the opening 21a in the insertion / removal direction of the electronic component 80 with respect to the component accommodating chamber 21 (FIGS. 1 to 6 and 8). The female screw member 10 and the connecting portion 51 are inserted into the terminal accommodating chamber 22 through the opening 22a in the direction opposite to the insertion direction of the electronic component 80. That is, the accommodating member 20 has the connecting portion 51 as the fastening object 50 and the female screw member 10 on the other side in the second orthogonal direction Go2 from the accommodation completion position of the female screw member 10 and the connecting portion 51 as the fastening object 50. It has an opening 22a for insertion when accommodating the member 10.

The connecting portion 51 and the terminal portion 52 are fastened by the female screw member 10 and the male screw member 40 in the terminal accommodating chamber 22. In the terminal accommodating chamber 22, an opening (work opening) 22b for screwing the female screw member 10 and the male screw member 40 is formed on the extension line of the screw shaft of the female screw member 10 in the accommodation completed state. (Fig. 1 and Fig. 2).

The conductive member 70A of this example has a rectangular flat plate-shaped main body 71 (FIGS. 1, 11 and 12). The subject 71 has four sides. In the conductive member 70A of this example, a male tab terminal 72 is provided on one of the two intersecting side portions of the main body 71 on the same plane, and a connecting portion 51 is provided on the other on the same plane. (FIGS. 1, 11 and 12). The male tab terminal 72 protrudes from the main body 71 along the insertion direction of the connecting portion 51 with respect to the terminal accommodating chamber 22. In the conductive member 70A of this example, the main body 71 and the male tab terminal 72 are also housed in the housing member 20. The conductive member 70B has a main body 71 and a male tab terminal 72 in the same manner as the conductive member 70A (FIG. 12). Further, in this exemplary accommodating member 20, apart from the electronic component 80, a component accommodating chamber 23 (FIG. 1) in which an electronic component (for example, a fuse) 85 (FIG. 2) is accommodated and an electronic component (for example, a fuse) are accommodated. ) 86 (FIG. 2) is accommodated, and a component accommodating chamber 24 (FIG. 1) is formed. The male tab terminal 72 of one of the conductive members 70A is electrically connected to the electronic component 85 housed in the component storage chamber 23. Further, the male tab terminal of the other conductive member 70B is electrically connected to the electronic component 86 housed in each of the two component accommodating chambers 24.

As shown above, the temporary holding mechanism 30A is composed of the accommodating member 20 and the fastening object 50. The temporary holding mechanism 30A is provided for each terminal accommodating chamber 22 of the accommodating member 20. The temporary holding mechanism 30A is provided in the terminal accommodating chamber 22 of the accommodating member 20, and has a first locking portion 31 for locking the first wall portion 13a of the first locked portion 13c in the screw axis direction, and the accommodating member 20. The terminal accommodating chamber 22 is provided with a second locking portion 32 for locking the first wall portion 13a of the second locked portion 13d in the screw axis direction (FIGS. 3, 7, and 9). Further, the temporary holding mechanism 30A is provided in the terminal accommodating chamber 22 of the accommodating member 20, and is accommodating the third locking portion 33 that locks the second wall portion 13b of the first locked portion 13c in the screw axis direction. It is provided in the terminal accommodating chamber 22 of the member 20, and has a fourth locking portion 34 that locks the second wall portion 13b of the second locked portion 13d in the screw axis direction (FIGS. 3 and 7). Further, the temporary holding mechanism 30A is provided in the terminal accommodating chamber 22 of the accommodating member 20, and is provided on the fifth locking portion 35 for locking the female screw member 10 on one side in the second orthogonal direction Go2 and the fastening object 50. It has a sixth locking portion 36 that locks the female screw member 10 on the other side in the second orthogonal direction Go2 (FIGS. 6 and 8). Further, the temporary holding mechanism 30A is provided in the terminal accommodating chamber 22 of the accommodating member 20, and has a seventh locking portion 37 for locking the female screw member 10 on one side in the first orthogonal direction Go1 and a terminal of the accommodating member 20. It is provided in the accommodation chamber 22 and has an eighth locking portion 38 for locking the female screw member 10 on the other side in the first orthogonal direction Go1 (FIGS. 3, 7, and 8). The temporary holding mechanism 30A temporarily holds the female screw member 10 by the first to eighth locking portions 31-38 until the male screw member 40 is in the screwing completed state.

The first locking portion 31 and the second locking portion 32 extend along the second orthogonal direction Go2. The female screw portion 11 of the female screw member 10 is interposed between the first locking portion 31 and the second locking portion 32, and protrudes from the space (FIG. 7).

The first locking portion 31 and the third locking portion 33 are formed so that the first locked portion 13c can be relatively moved along the screw axis direction between them (FIGS. 3 and 7). Then, the second locking portion 32 and the fourth locking portion 34 are formed so that the second locked portion 13d can be relatively moved along the screw axis direction between them (FIGS. 3 and 7). That is, in this temporary holding mechanism 30A, with respect to the flange portion 13 between the first locking portion 31 and the third locking portion 33 and between the second locking portion 32 and the fourth locking portion 34. By leaving a space in the screw axis direction, the female screw member 10 is relatively moved along the screw axis direction with respect to the accommodating member 20. Therefore, in the temporary holding mechanism 30A, when a force in the screw axis direction toward the third locking portion 33 and the fourth locking portion 34 acts on the female screw member 10, the female screw is applied in the direction in which the force is applied. The member 10 can be moved.

The fifth locking portion 35 may lock the female screw portion 11 in the second orthogonal direction Go2, or locks the third locked portion 13e in the second orthogonal direction Go2. May be good. In this example, the wall portion of the terminal accommodating chamber 22 arranged to face the third locked portion 13e in the second orthogonal direction Go2 is used as the fifth locking portion 35 (FIGS. 6 and 8).

The sixth locking portion 36 may lock the female screw portion 11 in the second orthogonal direction Go2, or locks the fourth locked portion 13f in the second orthogonal direction Go2. May be good. The sixth locking portion 36 projects from the fastening object 50 to the locked position on the female screw member 10 and is arranged to face the locked position. The sixth locking portion 36 of this example is formed to lock the fourth locked portion 13f. Here, the sixth locking portion 36 is provided on the conductive member 70 (70A, 70B) having the connecting portion 51 as the fastening object 50 (FIGS. 6 and 8). That is, the conductive member 70 (70A, 70B) of this example has a sixth locking portion 36 protruding from the connecting portion 51 (FIGS. 3 to 6, 11 and 12). Here, a piece bent from the connecting portion 51 in a direction orthogonal to the plane of the connecting portion 51 is used as the sixth locking portion 36.

Here, when the connecting portion 51 as the fastening object 50 with respect to the accommodating member 20 is in the accommodating completed state, the fifth locking portion 35 and the sixth locking portion 36 are along the second orthogonal direction Go2 between them. The female screw member 10 is formed so as to be relatively movable (FIGS. 6 and 8). Therefore, in this example, when the connecting portion 51 as the fastening object 50 with respect to the accommodating member 20 is in the accommodating completed state, the fifth locking portion 35 and the third locked portion 13e are second orthogonal to each other. A gap in the direction Go2 is provided, and a gap in the second orthogonal direction Go2 is provided between the sixth locking portion 36 and the fourth locked portion 13f.

The seventh locking portion 37 may lock the female screw portion 11 in the first orthogonal direction Go1, or locks the first locked portion 13c in the first orthogonal direction Go1. May be good. For example, when the female screw portion 11 is locked, the seventh locking portion 37 may be shared with the first locking portion 31. In this example, the wall portion of the terminal accommodating chamber 22 arranged to face the first locked portion 13c in the first orthogonal direction Go1 is used as the seventh locking portion 37 (FIGS. 3, 7, and 8). ).

The eighth locking portion 38 may lock the female screw portion 11 in the first orthogonal direction Go1, or locks the second locked portion 13d in the first orthogonal direction Go1. May be good. For example, when the female screw portion 11 is locked, the eighth locking portion 38 may be shared with the second locking portion 32. In this example, a wall portion arranged to face the second locked portion 13d in the first orthogonal direction Go1 is used as the eighth locking portion 38 (FIGS. 3, 7, and 8).

Here, the seventh locking portion 37 and the eighth locking portion 38 of this example are formed so that the female screw member 10 can be relatively moved along the first orthogonal direction Go1 between them (FIGS. 3 and 3). 7 and FIG. 8). Therefore, in this example, a gap in the first orthogonal direction Go1 is provided between the first locking portion 31 and the female screw portion 11 and between the second locking portion 32 and the female screw portion 11, respectively, and the first 7 A gap in the first orthogonal direction Go1 is provided between the locking portion 37 and the first locked portion 13c and between the eighth locking portion 38 and the second locked portion 13d, respectively. Here, the total value of the gap on the flange portion 13 side of the latter is made smaller than the total value of the gap on the female screw portion 11 side of the former.

By the way, the first to fourth locking portions 31-34 extend along the second orthogonal direction Go2 to the opening 22a of the terminal accommodating chamber 22 (FIGS. 6 and 8). As a result, in the temporary holding mechanism 30A, the first to fourth locking portions 31-34 guide the female screw member 10 inserted from the opening 22a of the terminal accommodating chamber 22 to the accommodating completion position. It is used as a mechanism. In this example, the female screw member 10 can be guided toward the accommodation completion position immediately after being inserted into the opening 22a.

Need to be provided. However, such a locking portion collides with the female screw member 10 when the female screw member 10 is accommodated in the terminal accommodating chamber 22. Therefore, when the locking portion receives the pushing force from the female screw member 10, it is necessary to temporarily retract the locking portion with an arm body or the like having flexibility. In the electrical connection box 1 of the present embodiment, since the sixth locking portion 36 is provided in the fastening object 50, the fastening object 50 is accommodated in the terminal after the female screw member 10 is accommodated in the terminal accommodating chamber 22. By accommodating it in the chamber 22, the movement of the female screw member 10 toward the opening 22a can be locked by the sixth locking portion 36 of the fastening object 50. As described above, the electric junction box 1 of the present embodiment does not need to be provided with a complicated mechanism such as an arm body having flexibility, so that the durability is improved while reducing the cost. Can be done.

Furthermore, in the electrical connection box 1 of the present embodiment, the female screw member 10 can be relatively moved with respect to the accommodating member 20 in the directions orthogonal to the screw axis direction (first orthogonal direction Go1 and second orthogonal direction Go2). it can. Therefore, in the electrical connection box 1, the misalignment of the screw shaft of the female screw member 10 with respect to the center of the through hole 51a of the connecting portion 51 and the through hole 52a of the terminal portion 52 can be corrected. Therefore, in the electrical connection box 1, workability when the female screw member 10 and the male screw member 40 are screwed together can be improved.

In the electrical connection box 1 of the present embodiment, when the female screw member 10 and the male screw member 40 are in the screwing completed state, the female is female with respect to the first locking portion 31 and the second locking portion 32. A pressing force can be applied from the first wall portion 13a of each of the first locked portion 13c and the second locked portion 13d in the flange portion 13 of the screw member 10. Then, in the electrical connection box 1, as long as the screwing completion state continues, the pressing force can be continuously applied, so that the female screw member 10 can be fixed to the accommodating member 20. Therefore, in the electrical connection box 1, as long as the screwing completion state continues, the object to be fastened by the female screw member 10 and the male screw member 40 (the connecting portion 51 of the conductive member 70 and the terminal portion 52 of the electronic component 80). Can be maintained in the fastened state.

When the conductive member 170 is completely accommodated with respect to the accommodating member 120, the connecting portion 151 brings one flat surface into surface contact with the holding portion 12 of the female screw member 10. In the accommodating member 120, the female screw member 10 is accommodated before the conductive member 170, and when the conductive member 170 is in the accommodation completed state, the connecting portion is substantially coaxial with the screw shaft of the female screw member 10. A through hole 151a of 151 is arranged. However, since the female screw member 10 can move relative to the accommodating member 120 as described later, the screw shaft may be eccentric with respect to the center of the through hole 151a within the range of the relative movement amount. .. The male tab terminal 172 is electrically connected to an electronic component (for example, a fuse) 185 (FIGS. 13 and 14).
