On the other hand, the second columnar part 22 enters between the adjacent first plate-like parts 11 and is locked by the two first plate-like parts 11.

  As shown in FIG. 6, the first plate-like portion 11 of the first locking portion 10 is inserted between the second plate-like portion 21 of the second locking portion 20 and the wall surface 31 a (second surface) . The size of the gap between the second plate-like portion 21 and the wall surface 31 a is slightly larger than the thickness of the first plate-like portion 11. Therefore, the second plate-like portion 21 can hold the first plate-like portion 11 between the second plate-like portion 21 and the wall surface 31 a, and can suppress rattling of the supported member 2. In addition, the second plate-like portion 21 is inserted between the first plate-like portion 11 and the side surface 2 a (first surface) of the supported member 2. The size of the gap between the first plate-like portion 11 and the side surface 2 a is slightly larger than the thickness of the second plate-like portion 21. Therefore, the first plate-like portion 11 can hold the second plate-like portion 21 between the first plate-like portion 11 and the side surface 2 a, and can suppress rattling of the supported member 2.

  As shown in FIG. 7, the one side engaging protrusion 14 a of the first locking portion 10 is the one side (the upper side in FIG. 7) of the second columnar portion 22 in the sliding direction (the upper side). Engage from the upper side of FIG. The locking surface 141 of the one side engaging protrusion 14 a faces the end face 22 a of the second columnar portion 22 in the sliding direction. The locking surface 141 of the one side engagement protrusion 14 a restricts the movement of the second columnar portion 22 toward one side (the upper side in FIG. 7) in the sliding direction. On the other hand, the other side engagement protrusion 14b engages with the end on the other side (lower side in FIG. 7) of the second columnar portion 22 in the sliding direction from the other side (lower side in FIG. 7). The locking surface 141 of the other side engagement protrusion 14 b faces the end face 22 b of the second columnar portion 22 in the sliding direction. The locking surface 141 of the other side engagement protrusion 14 b restricts the movement of the second columnar portion 22 toward the other side (the lower side in FIG. 7) in the sliding direction. Thus, the first locking portion 10 sandwiches the second columnar portion 22 from both sides in the sliding direction by the pair of engagement protrusions 14a and 14b, and the supported member 2 moves relative to the support 3 in the sliding direction Regulate to do.

  As shown in FIG. 8, the one side engaging protrusion 24 a of the second locking portion 20 is the one side (the upper side in FIG. 8) of the first columnar portion 12 in the sliding direction. It engages from the upper side of FIG. The locking surface 241 of the one side engaging protrusion 24 a faces the end surface 12 a of the first columnar section 12 in the sliding direction. The locking surface 241 of the one side engaging protrusion 24 a restricts the movement of the first columnar portion 12 toward one side (the upper side in FIG. 8) in the sliding direction. On the other hand, the other side engagement protrusion 24b engages with the end on the other side (lower side in FIG. 8) of the first columnar section 12 in the sliding direction from the other side (lower side in FIG. 8). The locking surface 241 of the other side engagement protrusion 24 b faces the end surface 12 b of the first columnar section 12 in the sliding direction. The locking surface 241 of the other side engagement protrusion 24 b restricts the movement of the first columnar portion 12 toward the other side (the lower side in FIG. 8) in the sliding direction. Thus, the second locking portion 20 sandwiches the first columnar portion 12 from both sides in the sliding direction by the pair of engagement protrusions 24a and 24b, and the supported member 2 moves relative to the support 3 in the sliding direction Regulate to do.

  When the supported member 2 is inserted into the first accommodation space 3 a, the one side support 15 a or the other side support 15 b is bent and deformed to allow the second column 22 to pass. For example, as shown by arrow Y1 in FIG. 9, when the first locking portion 10 is inserted upward in the sliding direction with respect to the support 3, the inclined surface 142 of the one side engagement protrusion 14a is the second Contact the columnar part 22. When the first locking portion 10 is further inserted upward in the sliding direction, the inclined surface 142 is pressed in the width direction by the second columnar portion 22. The pressing force from the second columnar portion 22 causes the one side support portion 15a to be bent and deformed. The bending deformation of the one side support portion 15 a causes the one side engagement protrusion 14 a to move in the width direction in the direction of separating from the second columnar portion 22 as shown by the arrow Y 2. The second columnar portion 22 deforms the one side support portion 15a and slides on the one side engagement protrusion 14a while inserting the space between the one side engagement protrusion 14a and the other side engagement protrusion 14b in the insertion direction. Moving. When the second columnar portion 22 reaches the space, the elastic restoring force of the one side support portion 15 a moves the one side engagement protrusion 14 a in the direction opposite to the arrow Y 2 direction, and engages with the second columnar portion 22. As a result, the second columnar section 22 is locked by the engagement protrusions 14a and 14b from both sides in the sliding direction, and is held in the first accommodation space 3a.

  Conversely, when the first locking portion 10 is inserted toward the lower side in the sliding direction with respect to the support 3, the inclined surface 142 of the other side engagement protrusion 14 b contacts the second columnar portion 22. It will be done. In this case, the other side support portion 15b is bent and deformed so that the other side engagement protrusion 14b moves in the width direction, and the second columnar portion 22 is allowed to pass.

  Further, the operation when the engaging projections 24a and 24b of the second plate-like portion 21 engage with the first columnar portion 12 is the same as that described above. When the supported member 2 is inserted into the first accommodation space portion 3a, the one side support portion 25a or the other side support portion 25b of the second plate-like portion 21 is bent and deformed to pass the first columnar portion 12 Tolerate.

  As described above, the locking structure 1 and the electrical connection box 100 of the present embodiment have the first locking portion 10 and the second locking portion 20. The first locking portion 10 has a first plate-like portion 11 and a first columnar portion 12. The first plate-like portion 11 has a first engagement protrusion 14 that locks the second columnar portion 22 in the sliding direction, and a flexible first support 15 that supports the first engagement protrusion 14. The first support portion 15 bends so that the first engagement protrusion 14 moves in a direction parallel to the first surfaces 2 a and 2 b and intersecting the slide direction. The first engagement protrusion 14 locks the second columnar portion 22 from one side in the sliding direction, and the other engagement engages the second columnar portion 22 from the other side in the sliding direction. It has a projection 14b.

  Therefore, according to the locking structure 1 and the electrical connection box 100 of the present embodiment, the supported member 2 can be inserted into and engaged with the support 3 from any direction in the sliding direction. Therefore, the locking structure 1 and the electrical connection box 100 of the present embodiment improve the degree of freedom of the assembling process (coupling process) for connecting the supported member 2 to the support 3.

  Further, the second plate-like portion 21 of the present embodiment has a second engaging protrusion 24 for locking the first columnar portion 12 in the sliding direction, and a flexible second support for supporting the second engaging protrusion 24. And a unit 25. The second support portion 25 bends so that the second engagement projection 24 moves in a direction parallel to the second surfaces 31a and 32a and intersecting the slide direction (for example, the width direction of the second surfaces 31a and 32a). . The second engagement protrusion 24 locks the first columnar portion 12 from one side in the slide direction, and the other engagement engages the first columnar portion 12 from the other side in the slide direction. It has a projection 24b.

  Therefore, according to the locking structure 1 and the electrical connection box 100 of the present embodiment, the engagement between the first columnar portion 12 and the second engagement protrusion 24, and the second columnar portion 22 and the first engagement protrusion 14 The supported members 2 are locked to the support 3 by the respective engagements of Thus, the stability of the locked state is improved by the supported member 2 being locked by the double lock structure.

  Further, the first locking portion 10 and the second locking portion 20 of the present embodiment respectively have male portions (engaging protrusions 14 and 24) and female portions (columnar portions 12 and 22) of a locking structure. There is. Therefore, the first locking portion 10 and the second locking portion 20 simultaneously function as both a male side and a female side depending on the configuration of the mating counterpart member. It is also possible. Therefore, the locking structure 1 of the present embodiment improves the degree of freedom of the connection process. For example, the support 3 having the first locking portion 10 (or the second locking portion 20) can be received by the supported member 2 having either the male or female locking structure.

  Further, since the first locking portion 10 and the second locking portion 20 have both the male portion and the female portion, they can be fitted with the locking portion having the same shape as itself. That is, the first locking portion 10 (or the second locking portion 20) can be made to have a standard shape of one type of lock, and it becomes unnecessary to design the male side and the female side separately.

  Moreover, the 1st latching | locking part 10 and the 2nd latching | locking part 20 of this embodiment have the strength of T-shaped rib, as it demonstrates below. In addition, "T-shaped rib" shows the rib whose cross-sectional shape orthogonal to the direction in which the rib extends is substantially T-shaped. For example, in the portion surrounded by the broken line R1 in FIG. 7, the adjacent second columnar portions 22 sandwich the first plate-like portion 11 from both sides in the width direction. That is, the plurality of second columnar portions 22 protruding from the second surfaces 31 a and 32 a are connected to each other by the first plate-like portion 11. The configuration of the R1 portion has strength against external force in the width direction, and can achieve the same strength improvement as that of the T-shaped rib. The same strength improvement can be realized also in the portion where the first columnar portion 12 and the second plate-like portion 21 are alternately adjacent to each other.

  With respect to the external force in the sliding direction, the engagement margin between the first engagement projection 14 and the second columnar section 22 and the engagement margin between the second engagement projection 24 and the first columnar section 12 have strength. Note that this strength can be adjusted by the width and area of the contact margin, the dimensions of the necks of the support portions 15 and 25, and the like. For external force in the direction orthogonal to the first surfaces 2a and 2b and in the direction orthogonal to the second surfaces 31a and 32a, the first locking portion 10 and the second locking portion 20 themselves are similar to T-shaped ribs. It has strength.

  The strength against twist will be described with reference to FIG. When an external force in the direction indicated by arrow Y3 in FIG. 8 (counterclockwise direction in FIG. 8) acts on the second locking portion 20, the contact portion between the second plate-like portion 21 and the first columnar portion 12 Has strength. The end faces of the second plate-like portion 21 and the first columnar portion 12 facing in the width direction are in surface contact with each other. The first columnar portion 12 supports the main body portion 23 of the second plate-like portion 21 against the external force in the twisting direction at the portion in surface contact. On the other hand, when an external force in the direction indicated by arrow Y4 in FIG. 8 (clockwise direction in FIG. 8) acts on the second locking portion 20, the support portions 25a and 25b bend and some twisting occurs. The engagement portion between the second engagement protrusion 24 and the first columnar portion 12 is increased, so that the locking portion has strength. Note that the arrangement of the engagement protrusions 24a and 24b in at least a part of the second plate-like portion 21 is changed from the rotationally symmetrical (diagonal) position to a laterally symmetrical (linearly symmetrical) position or a T-shaped arrangement. It is possible to control the deflection due to the external force in the twisting direction.

  Next, the strength against bending will be described with reference to FIG. As can be seen from FIG. 6 etc., in the VII-VII cross section, the second columnar parts 22 and the first plate-like parts 11 are alternately and adjacently arranged, and in the VIII-VIII cross section, the first columnar part 12 and the second The plate-like parts 21 are arranged alternately and adjacent to each other. Therefore, the locking structure 1 of this embodiment has the same strength as that of the T-shaped rib even when any of the external force in the bending direction shown by the arrow Y5 in FIG. 6 and the external force in the bending direction shown by the arrow Y6 acts. Demonstrate.

  Further, in the locking structure 1 and the electrical connection box 100 according to the present embodiment, when the supported member 2 is inserted into the support 3, the support portions 15, 25 have the first surface 2a, 2b and the second surface. It bends not in the direction orthogonal to 31a and 32a but in the direction parallel to these planes. Therefore, when setting the gap between the first surfaces 2a and 2b and the second surfaces 31a and 32a, an extra space for bending the support portions 15 and 25 becomes unnecessary. Therefore, space saving can be realized by narrowing the gap between the first surfaces 2a and 2b and the second surfaces 31a and 32a. Moreover, since the first locking portion 10 and the second locking portion 20 of the present embodiment do not have a hole or the like, the slide of the mold is not necessary at the time of manufacture.

More specifically, the other casing 102 can be assembled to one casing 102 from any direction in the sliding direction. Thus, the degree of freedom of the connection process for connecting the housings 102 is high. Moreover, it is also possible to connect one housing 102 and the other housing 102 such that the mounting surfaces 102a face in the opposite directions.

  The plurality of connected casings 102 may be housed in the case 103. FIG. 26 is a plan view showing an example of a case 103 for housing the case 102. As shown in FIG. The case 103 is a hollow or bottomed cylindrical member. The plurality of housings 102 connected to one another are housed inside the case 103 and held by the case 103. On the inner surfaces 103a and 103b along the long side of the case 103, a plurality of second locking portions 20 are arranged at predetermined intervals along the long side direction. The housing 102 is held by the case 103 by engagement of the first locking portion 10 of the housing 102 and the second locking portion 20 of the case 103. In connection between the housing 102 and the case 103, one of the housing 102 and the case 103 corresponds to a first member, and the other corresponds to a second member.

  In the case 102, the first locking portion 10 may be provided on the side surface other than the side surfaces 102b and 102c along the long side, for example, the side surface 102d along the short side. In this way, it is also possible to connect a plurality of casings 102 along the long side direction. In the case 103, the second locking portion 20 may be provided on the inner surfaces 103c and 103d along the short side. Further, the second locking portion 20 may be provided in the housing 102, and the first locking portion 10 may be provided in the case 103.
