Summary of the Invention

Problems to be Solved by the Invention

[0004] Incidentally, as a locking mechanism, for example, as in the protector of Patent Document 1 mentioned above, there is a first locking part that is flexible and provided between two through holes, and the first locking part and the second locking part are locked together by hooking the claw at the tip of the second locking part, which is inserted into one of the two through holes, onto the flexible part. In this type of locking mechanism, the first locking part is bent by the claw while the second locking part is inserted into one of the through holes, and when the claw comes out of the through hole, the deformation of the first locking part is released, so that the claw is positioned to be able to hook onto the first locking part. The other through hole is provided as a relief space for the first locking part to allow for deformation of the first locking part. In the protector of Patent Document 1 mentioned above, a cover plate for preventing misinsertion is placed over the other through hole to prevent the second locking part from being mistakenly inserted into the other through hole. However, in locking mechanisms, the second locking portion may also be made flexible, in which case there is a possibility that the deformed second locking portion may be guided into the other through-hole.

[0005] Therefore, the object of the present invention is to provide an assembly structure and a protector that can contribute to preventing the incorrect insertion of a locking mechanism. [Means for solving the problem]

The partition wall has a projection that extends from the orthogonal plane, and the peripheral edge of the through hole in the orthogonal wall has a first peripheral edge that is positioned opposite the partition wall with a gap on the side of the first through hole, a second peripheral edge that is positioned opposite the partition wall with a gap on the side of the second through hole, a third peripheral edge that is connected to the first peripheral edge and the partition wall, and a fourth peripheral edge that is positioned opposite the third peripheral edge with a gap and is connected to the first peripheral edge and the partition wall, and the first through hole is, The assembly member is formed in a rectangular shape enclosed by the first peripheral edge, the partition wall, the third peripheral edge, and the fourth peripheral edge. The second assembly member has a main body and a contact wall that extends vertically from the main body in the assembly direction and whose tip abuts against the orthogonal plane of the first peripheral edge at the completed assembly position. The locking mechanism utilizes the flexible partition wall as the first locking part, and the second locking part protrudes in the assembly direction with the contact wall side as the fixed end and is inserted into the first through hole at the completed assembly position. The assembly comprises a piece and a locking claw provided on the free end of the locking piece that exits the first through hole at the assembly completion position, which hooks onto the first locking portion at the assembly completion position to lock it in place, wherein the projection protrudes from the orthogonal plane on the second through hole side of the first through hole at the third peripheral edge, and when the second locking portion is inserted into the second through hole, it locks the tip of the contact wall, causing the second assembly member to float higher than when the second locking portion is inserted into the first through hole.

[0007] The protector according to the present invention comprises a housing member for housing the harness body through an opening, a cover member for attaching to the housing member to close the opening, and a locking mechanism that holds the housing member and the cover member in the assembled position by a first locking portion provided on the housing member and a second locking portion provided on the cover member locking together, wherein the housing member comprises an orthogonal wall provided with a plane perpendicular to the assembly direction of the cover member, a through hole provided in the orthogonal wall, and a partition wall that divides the through hole into a first through hole and a second through hole. The through-hole in the orthogonal wall has a projection extending from the orthogonal plane, and the peripheral edge of the through-hole in the orthogonal wall has a first peripheral edge positioned opposite the partition wall with a gap on the side of the first through-hole, a second peripheral edge positioned opposite the partition wall with a gap on the side of the second through-hole, a third peripheral edge connected to the first peripheral edge and the partition wall, and a fourth peripheral edge positioned opposite the third peripheral edge with a gap and connected to the first peripheral edge and the partition wall, and the first through-hole is the first The cover member is formed in a rectangular shape surrounded by the peripheral edge, the partition wall, the third peripheral edge, and the fourth peripheral edge. The cover member has a main body that closes the opening, and a contact wall that extends vertically from the main body in the assembly direction, with its tip contacting the orthogonal plane of the first peripheral edge at the completed assembly position. The locking mechanism utilizes the flexible partition wall as the first locking part, and the second locking part protrudes in the assembly direction with the contact wall side as the fixed end, and is inserted into the first through hole at the completed assembly position. The cover member comprises a locking piece and a locking claw provided on the free end of the locking piece that exits the first through hole at the completed assembly position, which hooks onto the first locking portion at the completed assembly position to lock it in place. The projection protrudes from the orthogonal plane on the second through hole side of the first through hole at the third peripheral edge, and when the second locking portion is inserted into the second through hole, it locks onto the tip of the contact wall, causing the cover member to float higher than when the second locking portion is inserted into the first through hole. [Effects of the Invention]

[0008] The protector (assembly structure) according to the present invention allows workers to recognize the incorrect insertion of the second locking portion even if it is inserted into the wrong second through-hole adjacent to the first through-hole, by using the projection of the housing member (first assembly member) to lift up the cover member (second assembly member). In this way, the protector (assembly structure) according to the present invention contributes to preventing incorrect insertion of the locking mechanism, and even if incorrect insertion of the second locking portion occurs, it can guide workers to reinsert the second locking portion into the correct first through-hole. Therefore, the protector (assembly structure) according to the present invention allows the housing member (first assembly member) and the cover member (second assembly member) to be assembled in the correct positions.

[Modes for carrying out the invention]

[0010] Embodiments of the assembly structure and protector according to the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to these embodiments.

[0011] [Embodiment] One embodiment of the assembly structure and protector according to the present invention will be described with reference to Figures 1 to 7.

[0012] Reference numeral 1 in Figures 1 to 4 indicates an assembly structure of this embodiment. This assembly structure 1 comprises a first assembly member 10, a second assembly member 20 to be assembled to the first assembly member 10, and a locking mechanism 30 to hold the first assembly member 10 and the second assembly member 20 in the assembled position (Figures 1 to 4). An example of this assembly structure 1 is a protector 1A that houses a part of the harness body (not shown) inside the room and protects it from the surroundings (Figures 1 to 4). This protector 1A comprises a housing member 10A as the first assembly member 10 that houses the harness body through the opening 10a, and a cover member 20A as the second assembly member 20 that is assembled to the housing member 10A to close the opening 10a (Figures 1 to 4). Furthermore, this protector 1A is equipped with a locking mechanism 30A that holds its housing member 10A and cover member 20A in the assembled position (Figures 1 to 4).

[0013] The housing member 10A (first assembly member 10) has a perpendicular wall 11 on which a plane 11a perpendicular to the assembly direction of the cover member 20A (second assembly member 20) is provided (Figures 1 to 4). The housing member 10A (first assembly member 10) has a through hole 12 provided in its perpendicular wall 11, a partition wall 13 that divides the through hole 12 into a first through hole 12a and a second through hole 12b, and a projection 14 that protrudes from the perpendicular plane 11a of the perpendicular wall 11 (Figures 1 to 4). The partition wall 13 is formed in a straight line shape that is flexible and can be deformed toward the first through hole 12a side and the second through hole 12b side.

[0014] For example, the housing member 10A has a bottom wall 15 and a pair of side walls 16 that form a housing chamber 10b along the wiring path of the harness main body (Fig. 5). The pair of side walls 16 are cantilevered wall bodies that are vertically provided from the bottom wall 15 at intervals from each other. In the housing member 10A, the space between the free ends of each of the pair of side walls 16 serves as the opening 10a of the housing chamber 10b. In this housing member 10A, an orthogonal wall 11 having an orthogonal plane 11a orthogonal to the vertical direction of the side wall 16 is provided in a continuous form at the free end of one of the side walls 16 (Fig. 5).

[0015] The peripheral edge 17 of the through-hole 12 in the orthogonal wall 11 includes a first peripheral edge 17a that is disposed opposite to the partition wall 13 with a space on the side of the first through-hole 12a, a second peripheral edge 17b that is disposed opposite to the partition wall 13 with a space on the side of the second through-hole 12b, a third peripheral edge 17c that is connected to the first peripheral edge 17a and the partition wall 13, and a fourth peripheral edge 17d that is disposed opposite to the third peripheral edge 17c with a space and is connected to the first peripheral edge 17a and the partition wall 13 (Figs. 1 to 4).

[0016] In the orthogonal wall 11, the first peripheral edge 17a and the second peripheral edge 17b are formed in a linear shape parallel to the linear partition wall 13 (Fig. 4). And in this orthogonal wall 11, the third peripheral edge 17c and the fourth peripheral edge 17d are formed in a linear shape in a form orthogonal to the first peripheral edge 17a, the second peripheral edge 17b, and the partition wall 13 (Fig. 4). Therefore, the first through-hole 12a is formed in a rectangular shape surrounded by the first peripheral edge 17a, the partition wall 13, the third peripheral edge 17c, and the fourth peripheral edge 17d.

[0017] Incidentally, the third peripheral edge 17c shown here is provided at the free end of one of the side walls 16 in the housing member 10A. Further, the peripheral edge 17 of the through-hole 12 shown here has a fifth peripheral edge 17e that connects the second peripheral edge 17b and the third peripheral edge 17c and obliquely connects the second peripheral edge 17b and the fourth peripheral edge 17d (Figs. 1, 2, and 4).

[0018] The cover member 20A (second assembling member 20) includes a main body 21 and an abutting wall 22 that is perpendicularly provided from the main body 21 in the assembling direction with respect to the accommodating member 10A (first assembling member 10), and the tip of which abuts on the orthogonal plane 11a of the first peripheral edge portion 17a at the assembling completion position with the accommodating member 10A (first assembling member 10) (FIGS. 1 to 4). In the cover member 20A, the opening 10a of the accommodating member 10A is closed by the main body 21.

[0019] The main body 21 has a flat plate portion 21a that is parallel to the orthogonal wall 11 at least around the orthogonal wall 11 at the assembling completion position (FIGS. 1 to 4). The abutting wall 22 protrudes in a flat plate shape from the flat plate portion 21a with a uniform protruding amount.

[0020] The locking mechanism 30A (locking mechanism 30) is provided as one of, for example, one or more of the same type of locking mechanisms 30A (locking mechanisms 30) at a plurality of locations or one of a plurality of types of locking mechanisms at a plurality of locations in the protector 1A (assembling structure 1). This locking mechanism 30A (locking mechanism 30) includes a first locking portion 31 provided on the accommodating member 10A (first assembling member 10) and a second locking portion 32 provided on the cover member 20A (second assembling member 20) (FIGS. 1 to 4). This locking mechanism 30A (locking mechanism 30) keeps the accommodating member 10A (first assembling member 10) and the cover member 20A (second assembling member 20) in the assembling completion position by the first locking portion 31 and the second locking portion 32 locking to each other.

[0021] This locking mechanism 30A (locking mechanism 30) uses the flexible partition wall 13 as the first locking portion 31.

[0022] The second locking portion 32 has a locking piece 32a that protrudes in the assembly direction of the cover member 20A (second assembly member 20) with the abutment wall 22 side as the fixed end, and is inserted into the first through hole 12a when the housing member 10A (first assembly member 10) and the cover member 20A (second assembly member 20) are assembled (Figures 1 to 4). This locking piece 32a is formed in a cantilever beam shape with the outer wall surface side of the abutment wall 22 as the fixed end, and is a flat plate shape parallel to the abutment wall 22, and protrudes beyond the tip of the abutment wall 22. The free end of this locking piece 32a is removed from the first through hole 12a when the assembly is completed.

[0023] The second locking portion 32 is provided at the free end of the locking piece 32a that exits the first through hole 12a when assembled, and has a locking claw 32b that hooks onto the first locking portion 31 when assembled (Figures 1 and 4). This locking claw 32b protrudes from the plane of the free end of the locking piece 32a.

[0024] In this locking mechanism 30A (locking mechanism 30), when the cover member 20A (second assembly member 20) is assembled to the housing member 10A (first assembly member 10), the second locking portion 32 is inserted into the first through hole 12a from the free end of the locking piece 32a, and the locking claw 32b at the free end of the second locking portion 31 bends toward the second through hole 12b. Then, in this locking mechanism 30A (locking mechanism 30), when the cover member 20A (second assembly member 20) reaches the completed assembly position with respect to the housing member 10A (first assembly member 10), the free end of the locking piece 32a comes out of the first through hole 12a together with the locking claw 32b, and the bending deformation of the first locking portion 31 is eliminated. As a result, in this locking mechanism 30A (locking mechanism 30), when the second locking portion 32 moves out of the first through hole 12a, the locking claw 32b catches on the first locking portion 31. Therefore, this locking mechanism 30A (locking mechanism 30) can keep the housing member 10A (first assembly member 10) and the cover member 20A (second assembly member 20) in the assembled position.

[0025] In this locking mechanism 30A (locking mechanism 30), a second through-hole 12b is provided adjacent to the first through-hole 12a in order to cause the first locking part 31 to bend and deform as the second locking part 32 is inserted into the first through-hole 12a. Therefore, in this locking mechanism 30A (locking mechanism 30), there is a possibility that the second locking part 32 may be mistakenly inserted into the second through-hole 12b. The projection 14 is provided to prevent the erroneous insertion of the second locking part 32.

[0026] The projection 14 protrudes from the orthogonal plane 11a on the side of the second through-hole 12b rather than the first through-hole 12a in the third peripheral edge 17c (Figures 1 to 4). When the second locking portion 32 is inserted into the second through-hole 12b, the projection 14 locks the tip of the contact wall 22, causing the cover member 20A (second assembly member 20) to lift up more than when the second locking portion 32 is inserted into the first through-hole 12a (Figures 6 and 7). Therefore, the projection 14 protrudes from the portion adjacent to the partition wall 13 to the portion located on the periphery of the second through-hole 12b in the orthogonal plane 11a of the third peripheral edge 17c.

[0027] For example, when assembling the cover member 20A (second assembly member 20) to the housing member 10A (first assembly member 10), the worker can visually confirm that the cover member 20A (second assembly member 20) is lifting up, thereby realizing that the second locking portion 32 in the locking mechanism 30A (locking mechanism 30) has been incorrectly inserted into the second through-hole 12b. Therefore, the projection 14 is made to protrude to a height that allows the lifting of the cover member 20A (second assembly member 20) to be visually confirmed when the tip of the contact wall 22 is locked. For example, the projection 14 is made to protrude to a height that creates a large gap between the orthogonal plane 11a of the orthogonal wall 11 in the housing member 10A (first assembly member 10) and the cover member 20A (second assembly member 20).

[0028] Incidentally, when the second locking portion 32 is inserted incorrectly, it is positioned inside the second through-hole 12b with a gap between it and the peripheral portion of the second through-hole 12b (partition wall 13, second peripheral portion 17b, third peripheral portion 17c, fourth peripheral portion 17d). Therefore, the shape and position of the projection 14 and the contact wall 22 must be adjusted so that they can lock together regardless of the position in the second through-hole 12b into which the second locking portion 32 is inserted. Accordingly, the projection 14 extends along the third peripheral portion 17c so that it can lock the tip of the contact wall 22 regardless of the position in the second through-hole 12b into which the second locking portion 32 is inserted. The contact wall 22 extends along the main body 21 so that its tip can lock onto the projection 14 regardless of the position in the second through-hole 12b into which the second locking portion 32 is inserted.

[0029] As described above, even if the second locking portion 32 of the protector 1A (assembly structure 1) of this embodiment is inserted into the wrong second through-hole 12b adjacent to the first through-hole 12a, the projection 14 of the housing member 10A (first assembly member 10) lifts up the cover member 20A (second assembly member 20), allowing the worker to recognize the incorrect insertion of the second locking portion 32. In this way, the protector 1A (assembly structure 1) of this embodiment contributes to preventing the incorrect insertion of the locking mechanism 30A (locking mechanism 30), and even if the incorrect insertion of the second locking portion 32 occurs, it can guide the worker to reinsert the second locking portion 32 into the correct first through-hole 12a. Therefore, the protector 1A (assembly structure 1) of this embodiment allows the housing member 10A (first assembly member 10) and the cover member 20A (second assembly member 20) to be assembled in the correct positions. Furthermore, the protector 1A (assembly structure 1) of this embodiment allows the worker to recognize the incorrect insertion of the second locking portion 32, thereby preventing situations such as continuing to push the second locking portion 32 into the wrong second through hole 12b, and thus preventing a decrease in the durability of the locking mechanism 30A (locking mechanism 30).
