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).

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 6 to 8). The flange portion 13 includes one first wall portion in the screw axis direction (that is, a first wall portion arranged on the holding portion 12 side in the screw axis direction) 13a (FIGS. 3, 6 and 7). 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 and 8) is provided. doing. 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. And FIG. 8) and the third locked portions 13e and the fourth cover at both ends of the second orthogonal direction Go2 (FIGS. 1, FIG. 2 and FIGS. 4 to 6) orthogonal to the screw axial direction and the first orthogonal direction Go1. It has a locking portion 13f (FIGS. 6 to 8).

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, 7, and 8). 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. In the flange portion 13 of this example, each of the four corners is chamfered.

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.

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 6 and 9).

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). 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, FIG. 2, FIGS. 4 to 6 and 9). 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.

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).

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. (Fig. 1). 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. Although not shown, the conductive member 70B has a main body and a male tab terminal like the conductive member 70A. 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.

The temporary holding mechanism 30A is provided in the terminal accommodating chamber 22. The temporary holding mechanism 30A is provided for each terminal accommodating chamber 22. The temporary holding mechanism 30A includes a first locking portion 31 that locks the first wall portion 13a of the first locked portion 13c in the screw axial direction, and a first of the second locked portions 13d in the screw axial direction. It has a second locking portion 32 that locks the wall portion 13a (FIG. 3). Further, the temporary holding mechanism 30A includes a third locking portion 33 that locks the second wall portion 13b of the first locked portion 13c in the screw axial direction, and a second locked portion 13d in the screw axial direction. It has a fourth locking portion 34 that locks the second wall portion 13b (FIGS. 3 and 9). Further, the temporary holding mechanism 30A locks the fifth locking portion 35 that locks the female screw member 10 on one side in the first orthogonal direction Go1 and the female screw member 10 on the other side in the first orthogonal direction Go1. It has a sixth locking portion 36 (FIGS. 3 and 9). Further, the temporary holding mechanism 30A locks the female screw member 10 on one side in the second orthogonal direction Go2 and the female screw member 10 on the other side in the second orthogonal direction Go2. It has an eighth locking portion 38 and (FIG. 6). 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. 3).

The third locking portion 33 is provided on the double-sided first arm body 39a having both ends fixed (FIGS. 3, 6 and 9). The third locking portion 33 is provided on the first flexible portion 39a ₁ capable of elastically deforming in the screw axis direction between the fixed ends of the first arm body 39a by the first arm body 39a (the third locking portion 33). 3, FIG. 6 and FIG. 9). A first arm member 39a, if the fixed end 39a ₂ on one side in the second orthogonal direction Go2 toward the other side (in other words, fixed end of the side which is disposed in the seventh engaging portion 37 39a ₂ The first flexible portion 39a ₁ is extended (toward the side where the eighth locking portion 38 is arranged) (FIGS. 6 and 9). Here, the first flexible portion 39a ₁ extending along the second orthogonal direction Go2 is used as the third locking portion 33.

The fourth locking portion 34 is provided on the double-sided second arm body 39b having both ends fixed (FIGS. 3 and 9). The fourth locking portion 34 is provided on the second flexible portion 39b ₁ capable of elastically deforming in the screw axis direction between the fixed ends of the second arm body 39b at the second arm body 39b ( 3 and 9). Its second arm member 39b, if the fixed end 39b ₂ on one side in the second orthogonal direction Go2 toward the other side (in other words, fixed end of the side which is disposed in the seventh engaging portion 37 39b ₂ The second flexible portion 39b ₁ is extended (toward the side where the eighth locking portion 38 is arranged) (FIG. 9). Here, the second flexible portion 39b ₁ extending along the second orthogonal direction Go2 is used as the fourth locking portion 34.

In this way, the third locking portion 33 can be elastically deformed in the screw axial direction, so that when a force is received from the second wall portion 13b of the first locked portion 13c along the screw axial direction, the third locking portion 33 can be elastically deformed. , Can be bent in the direction in which the force is applied. Similarly, since the fourth locking portion 34 can be elastically deformed in the screw axial direction, the fourth locking portion 34 receives a force along the screw axial direction from the second wall portion 13b of the second locked portion 13d. At that time, it can be bent in the direction in which the force is applied. Therefore, in the third locking portion 33 and the fourth locking portion 34, a force in the screw axis direction acting on the female screw member 10 acts on the female screw member 10, and the force is applied to the first locked portion 13c of the flange portion 13. When received from each of the second wall portions 13b of the second locked portion 13d, the female screw member 10 can be moved in the direction in which the force is applied along with the elastic deformation. Therefore, the temporary holding mechanism 30A can move the female screw member 10 relative to the accommodating member 20 along the screw axis direction.

The first arm body 39a and the second arm body 39b of this example are provided with one fixed end 39a ₁ , 39b ₁ and a shared fixed end 39c sharing the other fixed end. It is formed as an arm body 39 (FIG. 9). The arm body 39 can be elastically deformed in the screw axial direction provided between the first flexible portion 39a ₁ and the common fixed end 39c and between the second flexible portion 39b ₁ and the common fixed end 39c. It has a third flexible portion 39d (FIGS. 6 and 9). The third flexible portion 39d is formed in a T-shaped single body shape. The arm body 39 is provided for each temporary holding mechanism 30A (that is, for each terminal accommodating chamber 22) (FIG. 3). The arm bodies 39 are arranged so as to be spaced apart from each other along the arrangement direction of the terminal accommodating chambers 22 (that is, the screw axis direction), and the third flexible portions 39d are connected to each other via the common fixed end 39c. I'm letting you. In this example, the common fixed end 39c is formed in the shape of a rectangular flat plate having a plane along the screw axis direction. The common fixed end 39c of this example is arranged between the openings 22a of the respective terminal accommodating chambers 22. A space of at least a size that does not hinder the elastic deformation of the first flexible portion 39a ₁ , the second flexible portion 39b _1, and the third flexible portion 39d is provided between the arm bodies 39.

Here, the first locking portion 31 and the third locking portion 33 of this example are arranged to face each other so as to sandwich the first locked portion 13c in the screw axis direction. Then, the second locking portion 32 and the fourth locking portion 34 of this example are arranged to face each other so as to sandwich the second locked portion 13d in the screw axis direction. The term "sandwiched" as used herein means that the first locked portion 13c is sandwiched between the first locking portion 31 and the third locking portion 33, and the second locking portion 32 and the fourth locking portion 34 When the second locked portion 13d is sandwiched between the two, or the first locked portion 13c is interposed with a gap in the screw axis direction between the first locking portion 31 and the third locking portion 33. It shows one of the cases where the second locking portion 13d is interposed with a gap in the screw axis direction between the second locking portion 32 and the fourth locking portion 34. The gap is designed to sandwich the first locked portion 13c and the second locked portion 13d, but is caused by tolerance variation or the like, or is provided as a design value. To say.

When the first locked portion 13c and the second locked portion 13d are sandwiched, the third locking portion 33 and the fourth locking portion 34 of this example are forced in the screw axial direction toward them. Acts on the female screw member 10 to move the female screw member 10 in the direction in which the force is applied while immediately elastically deforming. On the other hand, when the first locked portion 13c and the second locked portion 13d are sandwiched with a gap, the third locking portion 33 and the fourth locking portion 34 of this example are directed toward them. When a force in the axial direction of the screw acts on the female screw member 10, the second wall portions 13b of the first locked portion 13c and the second locked portion 13d come into contact with each other, and then elastically deformed. The female screw member 10 is moved in the direction in which the force is applied. Therefore, the temporary holding mechanism 30A sandwiches the first locked portion 13c and the second locked portion 13d with a gap (particularly a design gap), so that the temporary holding mechanism 30A and the first locked portion 13c are sandwiched. The relative movement amount of the female screw member 10 with respect to the accommodating member 20 in the screw axis direction can be increased as compared with the case where the second locked portion 13d is sandwiched. The first to fourth locking portions 31-34 shown here are 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. Is formed so as to sandwich the first locked portion 13c and the second locked portion 13d of the flange portion 13.

Here, the first locking portion 31 and the second locking portion 32 extend along the second orthogonal direction Go2 toward the common fixed end 39c side of the eighth locking portion 38 (FIG. 6). Further, the first locking portion 31, the second locking portion 32, and the third flexible portion 39d have a flange portion between the first locking portion 31, the second locking portion 32, and the third flexible portion 39d. It is formed so as to sandwich the 13. As a result, in the temporary holding mechanism 30A, the first locking portion 31, the second locking portion 32, and the third flexible portion 39d are inserted into the female screw member from the opening 22a of the terminal accommodating chamber 22. It is used as a guide mechanism for guiding the 10 to the accommodation completion position. Therefore, the first locking portion 31 and the second locking portion 32 of this example extend to the opening 22a of the terminal accommodating chamber 22 so that the third flexible portion 39d also extends to the opening 22a. Together with this, the female screw member 10 can be inserted into the opening 22a and immediately guided toward the accommodation completion position. In this example, the fifth locking portion 35 and the sixth locking portion 36 are also extended along the second orthogonal direction Go2 toward the common fixed end 39c side of the eighth locking portion 38 (FIG. 9). ). Here, the fifth locking portion 35 and the sixth locking portion 36 extend to the opening 22a of the terminal accommodating chamber 22.

It should be noted that the sandwiching is when the collar portion 13 is sandwiched between the first locking portion 31, the second locking portion 32, and the third flexible portion 39d, or the first locking portion 31 and the second engaging portion. It shows one of the cases where the flange portion 13 is interposed with a gap in the screw axis direction between the stop portion 32 and the third flexible portion 39d. The gap is designed to sandwich the flange portion 13, but is caused by tolerance variation or the like, or is provided as a design value within a range that does not interfere with the guide function.

The fifth locking portion 35 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 fifth locking portion 35 may be shared with the first locking portion 31. In this example, a wall portion arranged to face the first locked portion 13c in the first orthogonal direction Go1 is used as the fifth locking portion 35 (FIGS. 3 and 9).

The sixth locking portion 36 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 sixth locking portion 36 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 sixth locking portion 36 (FIGS. 3 and 9).

The seventh locking portion 37 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 arranged to face the female screw portion 11 in the second orthogonal direction Go2 is used as the seventh locking portion 37 (FIG. 6).

The eighth locking portion 38 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. In this example, since the female screw member 10 is inserted into the terminal accommodating chamber 22 from the third locked portion 13e side, the fourth locked portion 13f is locked so as not to interfere with the insertion. The eighth locking portion 38 is formed as. The eighth locking portion 38 of this example is formed in a claw shape, and locks a substantially central portion of the fourth locked portion 13f in the second orthogonal direction Go2 (FIGS. 6 and 9). Here, the eighth locking portion 38 is provided on the third flexible portion 39d of the arm body 39. The eighth locking portion 38 is formed so as to project from the third flexible portion 39d in the direction of the screw axis in a claw shape, and the screw shaft is formed from the flange portion 13 of the female screw member 10 inserted into the terminal accommodating chamber 22. When a pressing force is applied in a direction, the third flexible portion 39d is elastically deformed in the direction of the force. After the flange portion 13 gets over the eighth locking portion 38, the elastic deformation of the third flexible portion 39d is eliminated and the eighth locking portion 38 returns to the original position, and becomes the fourth locked portion 13f in the second orthogonal direction Go2. Arranged facing each other.

Here, the fifth locking portion 35 and the sixth locking portion 36 of this example are formed so that the female screw member 10 can be relatively moved in the first orthogonal direction Go1 (FIGS. 3 and 9). 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 5 A gap in the first orthogonal direction Go1 is provided between the locking portion 35 and the first locked portion 13c and between the sixth locking portion 36 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. Further, 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 in the second orthogonal direction Go2 (FIG. 6). Therefore, in this example, a gap in the second orthogonal direction Go2 is provided between the seventh locking portion 37 and the female screw portion 11, and between the eighth locking portion 38 and the fourth locked portion 13f. Is provided with a gap in the second orthogonal direction Go2. The accommodating member 20 is not provided with a wall portion that is arranged to face the third locked portion 13e in the second orthogonal direction Go2. Therefore, the temporary holding mechanism 30A can move the female screw portion 11 relative to the accommodating member 20 in the first orthogonal direction Go1 and the second orthogonal direction Go2.

In the electrical connection box 1 of the present embodiment shown above, the third locking portion 33 and the fourth locking portion 34, which receive a force in the screw axial direction from the female screw member 10, can be bent in the direction of the force. Therefore, the female screw member 10 can be relatively moved in the direction of the force with respect to the accommodating member 20. Therefore, in the electrical connection box 1, when the fastening object 50 is installed on the holding portion 12 of the female screw member 10 in order to fasten the fastening object 50 between the female screw member 10 and the male screw member 40. Even if the female screw member 10 receives a force in the screw axial direction from the fastening object 50, the female screw member 10 can be relatively moved in the direction of the force with respect to the accommodating member 20. Therefore, in the electrical connection box 1, the force when the fastening object 50 is installed on the holding portion 12 of the female screw member 10 can be reduced, so that the installation workability can be improved.

Specifically, in the electrical connection box 1 of this example, the gap between the holding portion 12 of the female screw member 10 housed in the terminal accommodating chamber 22 and the connecting portion 51 of the conductive member 70 is the terminal of the electronic component 80. Even if it is narrower than the plate thickness of the portion 52, the terminal portion 52 that has begun to be inserted between the terminal portions 52 can push the female screw member 10 in the screw axis direction and widen the gap between them. Therefore, in the electrical connection box 1, the insertion force when the terminal portion 52, which is the object to be fastened 50, is inserted between the sandwiching portion 12 of the female screw member 10 and the connecting portion 51 of the conductive member 70 can be reduced. Therefore, the workability of inserting the terminal portion 52 can be improved, and the workability of inserting the electronic component 80 into the component storage chamber 21 can be improved accordingly.

Further, 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). .. 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.

Even if the connecting portion 151 of the conductive member 170 comes into contact with the conductive member 170, if the connecting portion 151 can be guided to the sandwiching portion 12 by continuing to insert the conductive member 170, the connecting portion 151 is female to the connecting portion 151 in the screw axis direction. The screw member 10 can be pushed. For example, in this example, the corner portion on the outer peripheral wall side of the tip portion of the female screw portion 11 is chamfered, and the chamfered portion guides the connecting portion 151 to the holding portion 12. Therefore, in the electrical connection box 101, the insertion force when the conductive member 170 provided with the connecting portion 151 as the object to be fastened 150 is inserted into the accommodating member 120 can be reduced, so that the conductive member 170 can be reduced. Insertion workability can be improved.

Further, in the electrical connection box 101 of the present embodiment, the female screw member 10 can be relatively moved with respect to the accommodating member 120 in the directions orthogonal to the screw axis direction (first orthogonal direction Go1 and second orthogonal direction Go2). .. Therefore, in the electrical connection box 101, the misalignment of the screw shaft of the female screw member 10 with respect to the center of the through hole 151a of the connecting portion 151 can be corrected. Therefore, in the electrical connection box 101, the workability when the female screw member 10 and the male screw member 40 are screwed together can be improved.

In the electrical connection box 101 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 131 and the second locking portion 132. 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 electric connection box 101, 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 120. Therefore, in the electrical connection box 101, as long as the screwing completion state continues, the fastening state of the object to be fastened 150 (connecting portion 151 of the conductive member 170) by the female screw member 10 and the male screw member 40 can be maintained. it can.
