The storage chamber 11B is a space in which the electronic control unit 90A is housed, and is formed according to the external shape of the housing 91 of the electronic control unit 90A. Therefore, the storage chamber 11B is formed as a square-shaped recessed space according to the external shape of the square-shaped housing 91.

The electronic control unit 90A is accommodated in the accommodating chamber 11B by being fitted and inserted while rotating around the axis of the rotating shaft 92 (FIG. 4). The rotation shaft 92 may be provided in either the accommodation chamber 11B or the electronic control unit 90A. In this example, two concentric rotation shafts 92 are provided at two corners of the housing 91 of the electronic control unit 90A in a protruding state. Each rotation shaft 92 protrudes from one of the four side walls (first side wall 91a) of the housing 91, and is inserted into the groove 21 (FIG. 3) of the accommodation chamber 11B, and each groove is inserted. It is rotatably arranged in 21.

The electronic control unit 90A includes a connector (hereinafter, referred to as “counterpart connector”) 93 at a position separated from each rotation shaft 92 along the intersecting direction (here, an orthogonal direction) of the axes connecting them. (Fig. 5). The position is on the side of the second side wall 91b as one of the outer wall portions of the housing 91 facing the first side wall 91a. The counterparty connector 93 of this example is a wall portion 91c of the housing 91 facing the wall portion 20a of the accommodating member 20 after the accommodation is completed, and is provided on the second side wall 91b side of the wall portion 91c.

In the electrical connection box 1, a connector 40 that is fitted to the mating connector 93 and physically and electrically connects the electrical connection portions (for example, terminals) to each other is arranged in the accommodation chamber 11B (FIG. FIG. 3). An electric wire We is physically and electrically connected to the connector 40, for example, in the accommodation chamber 11A inside the accommodation member 20. One of the connector 40 and the mating connector 93 is formed as a female connector and the other as a male connector, and the electronic control unit 90A is fitted and inserted into the accommodation chamber 11B and fitted between the connector 40 and the mating connector 93. It is inserted together.

In the electrical connection box 1, the electronic control unit 90A is accommodated up to the temporary accommodation position with respect to the accommodation chamber 11B (FIGS. 6 and 7), and the electronic control unit 90A is rotated around the axis of the rotation shaft 92 from the temporary accommodation position. It is fitted and inserted into the storage chamber 11B while being moved (FIGS. 1 and 2). The temporary accommodation position is a position where the rotating shaft 92 is inserted into the groove portion 21, and for example, the connector 40 and the mating connector 93 are in contact with each other at least before the mating insertion between the two starts. ..

The electrical connection box 1 includes a fitting structure 50 for assisting the fitting insertion work of the electronic control unit 90A into the accommodation chamber 11B (including the fitting insertion work of the mating connector 93 into the connector 40). (FIGS. 1 to 3 and 5 to 7). The fitting structure 50 fits and inserts the electronic control unit 90A into the accommodation chamber 11B while rotating the electronic control unit 90A accommodated to the temporary accommodation position with respect to the accommodation chamber 11B around the axis of the rotation shaft 92. The mating connector 93 and the connector 40 are configured to be fitted and inserted. Therefore, the fitting structure 50 is configured to apply a fitting insertion force at the time of each fitting insertion to the electronic control unit 90A. The point of action of the fitting insertion force on the electronic control unit 90A in the fitting structure 50 is provided so that the mating connector 93 is located on the action line along the action direction of the fitting insertion force, for example. Further, at the point of action of the fitting insertion force, the mating connector 93 is adjacently provided via the outer wall portion of the housing 91 of the electronic control unit 90A in the intersecting direction of the action lines along the action direction of the fitting insertion force. It may be provided as follows.

By providing such a fitting structure 50, the electrical connection box 1 of the present embodiment applies a fitting insertion force to the fitting insertion position between the mating connector 93 and the connector 40 or in the vicinity of the fitting insertion position. Can act. If the fitting structure 50 is not provided, for example, the direction of action of the fitting insertion force may vary from worker to worker, but in this electrical connection box 1, the direction of action of the fitting insertion force is set to a desired direction. Can be restricted. Therefore, since the electric connection box 1 can push the electronic control unit 90A along the regular fitting insertion locus as designed, the electronic control unit 90A is suppressed from being displaced with respect to the fitting insertion locus. Can be fitted and inserted into the accommodating chamber 11B while suppressing the deviation between the mating connector 93 and the connector 40. Therefore, the electrical connection box 1 can improve the workability of assembling the electronic control unit 90A to the storage chamber 11B. Further, the electrical connection box 1 can accommodate the electronic control unit 90A in the accommodation chamber 11B in the correct posture. Therefore, the electrical connection box 1 can establish an electrical connection state between the mating connector 93 and the connector 40, and the electronic control unit 90A and itself represented by the mating connector 93 and the connector 40. Durability can be improved. Furthermore, the electrical connection box 1 has a fitting insertion force because, for example, the frictional resistance between the mating connector 93 and the connector 40 at the time of fitting insertion becomes smaller as the fitting insertion is realized while suppressing the displacement. Can also be reduced. Therefore, in this electrical connection box 1, for example, it is not necessary for the operator to push the electronic control unit 90A into the storage chamber 11B with an excessive force, and from this point as well, the work of assembling the electronic control unit 90A into the storage chamber 11B is performed. It can be seen that the property is improved and the durability of the electronic control unit 90A and itself is also improved.

Hereinafter, one of specific examples of the fitting structure 50 will be described.

The fitting structure 50 is referred to as a fitting structure 51 provided in the housing 10 (here, the accommodating member 20) and a fitting structure provided in the electronic control unit 90A (hereinafter, referred to as “counterpart fitting structure”. ) 52 and (FIGS. 3 and 6). The fitting structure 51 is provided on the wall portion 20b of the accommodation member 20 facing the second side wall 91b of the electronic control unit 90A after the accommodation is completed. On the other hand, the mating structure 52 is provided on the second side wall 91b thereof.

The fitting structure 51 applies a fitting insertion force to the electronic control unit 90A via the mating structure 52. The fitting structure 51 includes an operation member 53 operated by an operator when generating the fitting insertion force, a fitting insertion force applying member 54 that applies a fitting insertion force to the electronic control unit 90A, and a fitting insertion force applying member 54. To be equipped. The fitting structure 51 is provided on the wall portion 20b of the accommodation member 20 facing the second side wall 91b of the electronic control unit 90A after the accommodation is completed.

The operating member 53 has a first rotating shaft 53a (FIG. 8) arranged parallel to the rotating shaft 92 at intervals, and the relative rotation of the first rotating shaft 53a with respect to the accommodating member 20 around the axis. It can be performed. The first rotating shaft 53a is rotatably attached to a projecting body 22 (FIGS. 1, 3 and 6) projecting outward from the wall portion 20b of the accommodating member 20. Further, the operating member 53 has a force point portion 53b to which an operator applies a force when generating a fitting insertion force. The power point portion 53b is a portion that is pushed along the axis of the first rotation shaft 53a, and is arranged at a position spaced apart from the first rotation shaft 53a in a direction orthogonal to the axis of the first rotation shaft 53a. To do. In the operating member 53, a rectangular flat plate portion having a plane parallel to the axis of the first rotating shaft 53a is used as the power point portion 53b.

The fitting insertion force applying member 54 has a second rotating shaft 54a (FIG. 8) arranged in parallel with the first rotating shaft 53a at intervals, and the second rotating shaft 54a with respect to the operating member 53. Relative rotation around the axis is possible. The second rotating shaft 54a is rotatably attached to the operating member 53 on the power point portion 53b side of the operating member 53 with respect to the first rotating shaft 53a. Therefore, the fitting insertion force applying member 54 is interlocked with the relative rotation of the operating member 53 with respect to the accommodating member 20, and with respect to the accommodating member 20, the direction of action of the fitting insertion force or the acting direction of the fitting insertion force. Can make relative movements in the opposite direction.

Here, the fitting insertion force applying member 54 is hooked on the mating insertion force 52 and relatively moved in the acting direction of the fitting insertion force in that state, thereby passing through the mating structure 52. A fitting insertion force is applied to the electronic control unit 90A. Therefore, in the fitting structure 50, the hooking portion 54b (FIG. 8) is provided on the fitting insertion force applying force member 54, and the hooked portion 52a (FIGS. 3 to 6) is provided on the mating fitting structure 52. .. The hook portion 54b is arranged so that the first rotation shaft 53a is positioned between the hook portion 54b and the second rotation shaft 54a. The hooked portion 52a is arranged so as to project from the second side wall 91b of the electronic control unit 90A. Here, the projecting body 52b is projected from the second side wall 91b, and the hooked portion 52a is formed on the projecting body 52b. For example, the hooked portion 52a is formed as a plate-like object protruding from the square-shaped projecting body 52b. The hooked portion 54b and the hooked portion 52a are arranged so that they can be hooked on each other when the electronic control unit 90A is in the temporary accommodation position.

The fitting structure 50 hooks the hooked portion 54b of the fitting insertion force applying member 54 to the hooked portion 52a of the electronic control unit 90A when the electronic control unit 90A is in the temporary accommodation position (FIGS. 6 and 7). FIG. 9). In the fitting structure 50, in the hooked state, a pushing operation is performed on the force point portion 53b of the operating member 53 in the direction of action of the fitting insertion force. As a result, in the fitting structure 50, the fitting insertion force applying member 54 rotates relative to the operating member 53 as well as the operating member 53 relative to the accommodating member 20 accompanying the pushing operation to the force point portion 53b. While moving relative to the accommodating member 20 in the direction of action of the fitting insertion force. In the fitting structure 50, along with the relative movement of the fitting insertion force applying member 54, the fitting insertion force is transmitted from the hooking portion 54b of the fitting insertion force applying member 54 to the electronic control unit 90A via the hooked portion 52a. Make it work. That is, in the fitting structure 50, the contact point between the hooked portion 54b and the hooked portion 52a is the point of action of the fitting insertion force on the electronic control unit 90A. The fitting structure 50 continues to exert a fitting insertion force on the electronic control unit 90A by continuing the pushing operation of the operating member 53 with respect to the power point portion 53b, and the accommodation chamber 11B of the electronic control unit 90A. Containment in (FIGS. 1 and 2). Therefore, the electronic control unit 90A is fitted and inserted into the accommodation chamber 11B with a lighter force than when the operator directly pushes it.

As described above, the fitting structure 50 utilizes the principle of leverage, and enables further reduction of the fitting insertion force. Therefore, the electrical connection box 1 of the present embodiment can further improve the workability of assembling the electronic control unit 90A to the accommodation chamber 11B by using the fitting structure 50.

Here, in the fitting structure 50, the electronic control unit 90A is accommodated by completing the fitting insertion of the electronic control unit 90A into the accommodation chamber 11B and the fitting insertion between the mating connector 93 and the connector 40. Even after the accommodation in the chamber 11B is completed, the hooked portion 54b and the hooked portion 52a are hooked on each other. That is, in the fitting structure 50, the hooked portion 54b and the hooked portion 52a form a holding mechanism for the electronic control unit 90A in the accommodation chamber 11B. Therefore, the fitting structure 50 can also maintain the accommodation state of the electronic control unit 90A in the accommodation chamber 11B after the accommodation of the electronic control unit 90A is completed.

In the fitting structure 50, after the electronic control unit 90A is completely accommodated, the flat surface of the flat plate-shaped force point portion 53b of the operating member 53 is substantially parallel to the outer flat surface of the flat plate-shaped wall portion 20b of the accommodating member 20. Therefore, it is desirable that the fitting insertion force applying member 54 stops at a position equivalent to the plane of the force point portion 53b or on the wall portion 20b side of the plane of the force point portion 53b when viewed from the plane of the wall portion 20b. .. As a result, the fitting structure 50 can suppress the amount of protrusion of the electric connection box 1 to the outside as much as possible, and contributes to the suppression of the increase in the physique of the electric connection box 1.

Further, in the electric connection box 1 adopting the fitting structure 50, the electric connection box 1 is hooked by performing a pushing operation on the power point portion 53b of the operating member 53 in the direction opposite to that at the time of assembling the electronic control unit 90A. The hook between the portion 54b and the hooked portion 52a is released. However, since the fitting structure 50 does not apply a force to the electronic control unit 90A when the hook is released, the electronic control unit 90A is still housed in the storage chamber 11B. Therefore, in this electrical connection box 1, when the electronic control unit 90A is removed from the accommodation chamber 11B, a separate lever member (hereinafter, referred to as “removal lever”) L is used (FIGS. 10 and 11). Then, the electrical connection box 1 is provided with a storage state release structure 60 for releasing the storage state of the electronic control unit 90A in the storage chamber 11B with the removal lever L.

The accommodation state release structure 60 is configured by utilizing the protrusion 22 of the accommodation member 20 and the protrusion 52b of the mating structure 52 of the electronic control unit 90A. In the accommodation state release structure 60, the protrusion 22 of the accommodation member 20 is arranged on the side in the acting direction of the fitting insertion force with respect to the protrusion 52b of the electronic control unit 90A. Then, the respective projecting bodies 22 and 52b are formed and arranged so that the gap C between them is of a size that allows the removal lever L to be inserted. Here, the tip L1 of the removal lever L is formed in a plate shape so that the plate-shaped tip L1 is inserted into the gap C.

The removal lever L is formed so as to protrude from the gap C with the tip L1 inserted in the gap C. In this removal lever L, a force point portion L2 is provided at a protruding portion thereof, and when the electronic control unit 90A is removed, an operator applies a force to the force point portion L2. Further, the removal lever L removes the electronic control unit 90A by utilizing the principle of leverage according to the force thereof, and a fulcrum and an action point are provided at the tip L1.

The gap C between the protruding bodies 22 and 52b is opposite to the direction of action of the fitting insertion force or the direction of action of the fitting insertion force on the force point portion L2 of the removal lever L inserted into the gap C. When an directional force is applied, one of the contact points between the projecting body 22 of the accommodating member 20 and the tip L1 of the removing lever L and the contact point between the projecting body 52b of the electronic control unit 90A and the tip L1 of the removing lever L It is formed so that it becomes a fulcrum and the other of them becomes a force point. In other words, here, the projecting bodies 22 and 52b are formed and arranged so that such a gap C is formed.

In the accommodation state release structure 60, the operator moves the removal lever L in this way, so that the second side wall 91b side of the electronic control unit 90A is pushed out from the accommodation chamber 11B. Therefore, it is desirable that the respective projecting bodies 22 and 52b are formed and arranged so that the electronic control unit 90A is pushed out to at least the temporary accommodation position. As a result, the electronic control unit 90A can be easily removed from the storage chamber 11B.

By the way, in the fitting structure 50 shown above, the operating member 53 can freely rotate around the axis of the first rotating shaft 53a and the fitting insertion force is applied until the hooked portion 54b and the hooked portion 52a are hooked on each other. The member 54 can also freely rotate around the axis of the second rotation shaft 54a. Therefore, in the fitting structure 50, the positions of the operating member 53 and the fitting insertion force applying member 54 with respect to the accommodating member 20 are not determined until the hooking operation is performed. There is a possibility of getting caught in such things.

Therefore, the electrical connection box 1 is provided with a temporary locking structure 70 for temporarily fixing the operating member 53 and the fitting insertion force applying member 54 to the accommodating member 20 (FIGS. 12 and 13). The temporary locking structure 70 locks the fitting insertion force applying member 54 with respect to the accommodating member 20 to suppress the relative rotation of the operating member 53 with respect to the accommodating member 20 and operate the fitting insertion force applying member 54. It is configured to suppress the relative rotation with respect to the member 53.

For example, the temporary locking structure 70 is provided in the locking portion 71 provided on the flexible body 23 protruding from the accommodating member 20, and the locking portion 71 provided in the fitting insertion force applying member 54. A locked portion 72 that can be locked against the vehicle is provided.

For example, two L-shaped L-shaped bodies 24 are projected outward from the wall portion 20b on the accommodating member 20. In each L-shaped body 24, the first piece of each rectangle extending in the direction of action of the fitting insertion force is vertically hung from the wall part 20b toward the outside, and each first piece is a protruding body. 22 are arranged facing each other at intervals so as to intervene. Further, in each L-shaped body 24, the second piece portion is arranged at the end portion of the first piece portion on the protruding direction side, and each second piece portion is projected toward the other. The flexible body 23 is arranged at each end of the second piece thereof on the protruding direction side. For example, the flexible body 23 is formed as a piece extending in the protruding direction from the wall portion 20b of the first piece, and the central portion in the extending direction is on the protruding direction side of the second piece. Integrate at the end. For example, the flexible body 23 uses a joint portion with the second piece portion as a fulcrum, and applies a force to one wall surface of the two piece-shaped parts protruding from the joint portion to allow the other. The whole is tilted so as to move away from or closer to the flexible body 23. Further, the flexible body 23 may be formed so that such a tilting operation is performed while moving integrally with the L-shaped body 24 by giving the L-shaped body 24 flexibility as well.

The locking portion 71 is provided on the side opposite to the wall portion 20b among the respective piece-shaped portions. For example, the locking portion 71 is on the other flexible body 23 side in the one-sided portion to be installed so that the movement of the fitting insertion force applying member 54 in the intersecting direction with respect to the plane of the wall portion 20b can be locked. It is formed as a concave shape with respect to the wall surface of. As the concave one, a groove-shaped one, a concave one, and the like can be considered. The locking portion 71 of this example is formed as a groove portion. The groove-shaped locking portion 71 extends, for example, in the direction of action of the fitting insertion force so that the wall surface of each side wall intersects the intersection axis with respect to the plane of the wall portion 20b.

Two locked portions 72 are provided with respect to the fitting insertion force applying force member 54 in accordance with the positions of the two locking portions 71. The locked portion 72 is arranged on the hooking portion 54b side of the second rotating shaft 54a. The locked portion 72 of this example is a protruding portion that protrudes outward from the fitting insertion force applying force member 54, and is formed in a shape that is fitted into the groove-shaped locking portion 71.

In this temporary locking structure 70, by fitting the protruding locked portion 72 into the groove-shaped locking portion 71, the second rotating shaft 54a of the fitting insertion force applying force 54 to the accommodating member 20 Relative rotation around the axis is locked. At that time, the flexible body 23 is bent by being pushed by the locked portion 72 in a piece-shaped portion protruding to the opposite side of the wall portion 20b. Along with this, in the temporary locking structure 70, the relative rotation of the second rotating shaft 54a between the operating member 53 and the fitting insertion force applying member 54 is restricted, and as a result, the relative rotation around the axis is restricted. The relative rotation of the operating member 53 with respect to the accommodating member 20 around the axis of the first rotating shaft 53a is also locked. Therefore, the electrical connection box 1 is durable because it can suppress inadvertent contact with parts around the operating member 53 and the fitting insertion force applying member 54, for example, when the electrical connection box 1 is being conveyed. It is possible to improve sex and yield.

Further, the temporary locking structure 70 may include a structure for releasing the locked state. For example, in this temporary locking structure 70, the flexible body 23 is pushed and flexed by the pushing body 94 of the electronic control unit 90A until the electronic control unit 90A is accommodated to the temporary housing position. It is formed so that the locked state between the locked portion 71 and the locked portion 72 is released (FIGS. 13 and 14). The pushing body 94 is provided for each flexible body 23 with respect to the housing 91 of the electronic control unit 90A. The pushing body 94 is a protruding body that protrudes outward from the second side wall 91b of the housing 91. In the process of accommodating the electronic control unit 90A to the temporary accommodating position, the pushing body 94 is in the flexible body 23 so that the one-sided portion on the opposite side of the wall portion 20b of the flexible body 23 is further bent. The one-sided portion on the wall portion 20b side is pushed. Therefore, the pushing body 94 of this example is formed and arranged so as to push the wall surface of the other flexible body 23 side in the one-sided portion on the wall portion 20b side. Here, at least one of the contact portions of the flexible body 23 and the pushing body 94 is formed in a tapered shape so that the pushing body 94 does not get caught in the flexible body 23 until the pushing starts. As described above, since it is not necessary for the operator to separately release the locked state of the temporary locking structure 70, the electrical connection box 1 can be assembled to the accommodation chamber 11B of the electronic control unit 90A from this point as well. Workability can be improved.

When the electronic control unit 90A is accommodated to the temporary accommodation position, the flexible body 23 and the pushing body 94 are released from the contact state between the flexible body 23 and the pushing body 94, and the pushing body 94 can be used. It is desirable that the shape and arrangement of the flexible body 23 eliminate the bending (FIG. 14). Further, it is desirable that the flexible body 23 is formed and arranged so as not to come into contact with other peripheral parts so that the electronic control unit 90A does not bend when it is completely accommodated in the accommodation chamber 11B (FIG. FIG. 15). As a result, in the electrical connection box 1, an unnecessary load does not act on the flexible body 23, so that the durability can be improved.

As shown above, the electrical connection box 1 of the present embodiment can obtain various effects as shown above. Since the wire harness WH of the present embodiment includes the electric connection box 1, the effect of the electric connection box 1 can be exhibited.

The connecting portion 153 can be used as a lever operating portion when the operator rotates the lever member 150A.

When the lever member 150A is rotated relative to the projecting body 122 by applying a force to the connecting portion 153, each of the second lever pieces 152b is placed on the wall portion 91d of the housing 91 or the wall in the housing 91. It is formed so as to abut the boundary portion (corner portion) between the portion 91d and the second side wall 91b (FIGS. 16 to 18). In the fitting structure 150, the contact portion between the second lever piece 152b and the housing 91 is the point of action of the fitting insertion force. For example, the lever member 150A is formed and arranged so that the point of action approaches the wall portion 20b of the accommodating member 20 as the relative rotation progresses. In the fitting structure 150, by continuing to rotate the lever member 150A relative to each other, the electronic control unit 90A is fitted and inserted into the accommodation chamber 11B, and the accommodation of the electronic control unit 90A in the accommodation chamber 11B is completed. (FIGS. 19 and 20).

[Modification 2]
Reference numerals 3 in FIGS. 21 to 24 indicate an electrical connection box of this modification. The electric connection box 3 of this modification corresponds to the one in which the fitting structure 50 is replaced with the following fitting structure 250 in the electric connection box 1 of the above-described embodiment. Here, for convenience of explanation, the same parts and parts as the electric connection box 1 of the embodiment, strictly speaking, parts and parts different from the electric connection box 1 but substantially equivalent to the electric connection box 1 are referred to in the electric connection box 1. The same reference numerals are given to those of the same, and the specific description thereof will be omitted.

In the fitting structure 250 of this modification, similarly to the fitting structure 50 of the embodiment, the electronic control unit 90A housed up to the temporary storage position with respect to the storage chamber 11B is rotated around the axis of the rotation shaft 92. The electronic control unit 90A is fitted and inserted into the accommodation chamber 11B, and the mating connector 93 and the connector 40 are fitted and inserted. Therefore, also for this fitting structure 250, the point of action of the fitting insertion force on the electronic control unit 90A is, for example, such that the mating connector 93 is located on the line of action along the direction of action of the fitting insertion force, or. The mating connector 93 is provided adjacent to the electronic control unit 90A via the outer wall portion of the housing 91 in the intersecting direction of the action lines along the action direction of the fitting insertion force.

The fitting structure 250 includes a guided body 251 provided in the electronic control unit 90A and a first guide portion 252a for guiding the guided body 251, and the guide member 252 that can move relative to the accommodating member 20. , A guide portion provided on the accommodating member 20, and includes a second guide portion 253 for guiding the guided body 251.

The guided body 251 is a projecting body that protrudes outward from the second side wall 91b of the housing 91 of the electronic control unit 90A. The guided body 251 of this example is formed as a cylinder or a cylinder whose protruding direction is the axial direction.

The guide member 252 is formed in a plate shape (FIG. 25), and is arranged on the accommodating member 20 with one wall surface facing the outer wall surface of the wall portion 20b of the accommodating member 20. The guide member 252 is attached to the accommodating member 20 so that it can move relative to the wall surface of the wall portion 20b. The housing member 20 of this example is formed with a storage space 222 in which the wall surface of the wall portion 20b is one of the inner wall surfaces. The accommodation space 222 is a space for accommodating the guide member 252 in a relatively movable state, and also serves as a guide portion of the guide member 252 during the relative movement.

The first guide portion 252a is formed so as to guide the guided body 251 and exert a fitting insertion force on the guided body 251. The first guide portion 252a may exert a fitting insertion force itself along a desired acting direction on the guided body 251, and the fitting insertion force acts as a component force. There may be. For example, the first guide portion 252a is formed in the guide member 252 as a groove portion or a through hole portion in which the guided body 251 is housed, and has two side walls facing the peripheral wall of the guided body 251. .. With the relative movement of the guide member 252, one of the two side walls of the first guide portion 252a abuts on the peripheral wall of the guided body 251 and exerts a fitting insertion force on the guided body 251 from the side wall. The guided body 251 is guided while being guided. In the fitting structure 250, the contact portion between the side wall of the first guide portion 252a and the peripheral wall of the guided body 251 is the point of action of the fitting insertion force.

The second guide portion 253 is a through hole along the acting direction of the fitting insertion force, and is formed on the second side wall 91b of the housing 91. The second guide portion 253 regulates that when a force is applied to the guided body 251 from the first guide portion 252a, the moving direction of the guided body 251 does not deviate from the acting direction of the fitting insertion force. It is a thing.

For example, the guide member 252 of this example is moved relative to the wall surface of the wall portion 20b and in a direction orthogonal to the acting direction of the fitting insertion force. When the guide member 252 is relatively moved in one of the relative movement directions, the first guide portion 252a is directed from the side wall thereof to the peripheral wall of the guided body 251 at least in the direction of action of the fitting insertion force. It is formed in an arc shape so that the force of can be applied.

By configuring the fitting structure 250 in this way, for example, the guide member 252 is relatively moved in one relative movement direction from the state shown in FIGS. 21 and 22 (for example, the temporary accommodation position of the electronic control unit 90A). , The guided body 251 can be guided in the direction of action of the fitting insertion force, and the electronic control unit 90A can be fitted and inserted into the accommodation chamber 11B. Then, the fitting structure 250 completes the accommodation of the electronic control unit 90A in the accommodation chamber 11B by continuing the relative movement of the guide member 252 (FIGS. 23 and 24).

Further, in the fitting structure 250, the guide member 252 is relatively moved from the accommodation completion position of the electronic control unit 90A to the other relative movement direction, so that the guided body 251 is set to the action direction of the fitting insertion force. Can guide in the opposite direction. Therefore, the fitting structure 250 can push the electronic control unit 90A out of the accommodation chamber 11B to the temporary accommodation position only by performing the operation opposite to that at the time of accommodation. That is, the fitting structure 250 can facilitate the removal of the electronic control unit 90A without using the removal lever L as in the embodiment.

Here, in the fitting structure 250, an operation lever member 254 that is operated when the guide member 252 is relatively moved is provided. The operation lever member 254 is arranged, for example, on one end side of the guide member 252 in the relative movement direction so that it can be rotated. The fitting structure 250 includes a power conversion mechanism 255 that converts the rotational torque associated with the rotational operation of the operating lever member 254 into a force in the relative moving direction of the guide member 252 (FIG. 25). The power conversion mechanism 255 is interposed between the guide member 252 and the operating lever member 254. For example, as the power conversion mechanism 255, a so-called rack and pinion mechanism including a rack gear 255a provided on the guide member 252 and a pinion gear 255b provided on the operating lever member 254 can be used. In the fitting structure 250, the guide member 252 is relatively moved to one side by rotating the operation lever member 254 to one side, and the electronic control unit 90A is housed in the storage chamber 11B. On the other hand, when the operation lever member 254 is rotated to the other side, the guide member 252 can be relatively moved to the other side, and the electronic control unit 90A can be pushed out from the accommodation chamber 11B.

Even if such a fitting structure 250 is used, the electric connection box 3 of the present modification can obtain various effects equivalent to those of the electric connection box 1 of the above-described embodiment. Since the wire harness WH (not shown) of this modified example includes the electric connection box 3, the effect of the electric connection box 3 can be exhibited.

Reference numeral 4 in FIGS. 26 and 27 indicates an electrical connection box of this modification. The electric connection box 4 of this modification corresponds to the one in which the fitting structure 50 is replaced with the following fitting structure 350 in the electric connection box 1 of the above-described embodiment. Here, for convenience of explanation, the same parts and parts as the electric connection box 1 of the embodiment, strictly speaking, parts and parts different from the electric connection box 1 but substantially equivalent to the electric connection box 1 are referred to in the electric connection box 1. The same reference numerals are given to those of the same, and the specific description thereof will be omitted.

In the fitting structure 350 of this modification, similarly to the fitting structure 50 of the embodiment, the electronic control unit 90A housed up to the temporary storage position with respect to the storage chamber 11B is rotated around the axis of the rotation shaft 92. The electronic control unit 90A is fitted and inserted into the accommodation chamber 11B, and the mating connector 93 and the connector 40 are fitted and inserted. Therefore, also for this fitting structure 350, the point of action of the fitting insertion force on the electronic control unit 90A is, for example, such that the mating connector 93 is located on the line of action along the direction of action of the fitting insertion force, or. The mating connector 93 is provided adjacent to the electronic control unit 90A via the outer wall portion of the housing 91 in the intersecting direction of the action lines along the action direction of the fitting insertion force.

This fitting structure 350 corresponds to the fitting structure 250 of the second modification described above in which the operation lever member 254 and the power conversion mechanism 255 are omitted. Therefore, the fitting structure 350 includes a guided body 351 similar to the guided body 251, a guide member 352 similar to the guide member 252, and a second guide portion 353 similar to the second guide portion 253. A first guide portion 352a similar to the first guide portion 252a is formed on the guide member 352.

Since the guide member 352 can be relatively moved in the accommodation space 222 of the accommodation member 20 in the fitting structure 350 as in the fitting structure 250 of the modification 2, the accommodation chamber 11B of the electronic control unit 90A Can be accommodated and removed. Therefore, the electric connection box 4 and the wire harness WH (not shown) of the present modification can obtain the same effect as the electric connection box 3 and the wire harness WH of the modification 2. Further, in the electric connection box 4 and the wire harness WH, the fitting structure 350 does not require an operation lever member or a power conversion mechanism, so that the cost is reduced as compared with the electric connection box 3 and the wire harness WH of the second modification. And the size of the physique can be reduced. On the other hand, if the operability of the fitting structure is prioritized over the cost reduction and the miniaturization of the physique, it is desirable to use the fitting structure 250 of the modified example 2 instead of the fitting structure 350.

The combination of the guided portion 422a and the guide portion 452b _{1 and} the combination of the guided portion 422b and the guide portion 452b ₂ are guided to each other by each combination, so that the guide member 452 is eccentric with respect to each plate-shaped portion 422. It is formed and arranged so as to move relative to the direction of action of the fitting insertion force while rotating. So to speak, the guide member 452 is attached to each plate-shaped portion 422 while being configured to act like a so-called LIF lever.

By performing the relative movement of the guide member 452 from, for example, the temporary accommodation position of the electronic control unit 90A, the guide member 452 is moved from the side wall of the first guide portion 452a to the peripheral wall of the guided body 451 at least in the direction of action of the fitting insertion force. Apply force. At that time, since the movement of the guided body 451 is restricted by the second guide portion 453, the guided body 451 moves in the action direction of the fitting insertion force. Therefore, the electronic control unit 90A is fitted and inserted into the accommodation chamber 11B, and finally the accommodation in the accommodation chamber 11B is completed.

On the other hand, the guide member 452 can guide the guided body 451 in the direction opposite to the acting direction of the fitting insertion force by moving the guide member 452 in the direction opposite to the relative moving direction. Therefore, the fitting structure 450 can push the electronic control unit 90A out of the accommodation chamber 11B to the temporary accommodation position only by performing the operation opposite to that at the time of accommodation. That is, the fitting structure 450 can facilitate the removal of the electronic control unit 90A without using the removal lever L as in the embodiment.

Even if such a fitting structure 450 is used, the electric connection box 5 of the present modification can obtain various effects equivalent to those of the electric connection box 1 of the embodiment shown above. Since the wire harness WH (not shown) of this modification includes the electric connection box 5, the effect of the electric connection box 5 can be exhibited.
