[0001] The present invention relates to terminal parts. Background Art
[0002] The terminal part of Patent Document 1 is an L-shaped metal plate as a whole, and has a bent portion, a terminal box portion extending from the bent portion in a first direction, and a wire connecting portion extending from the bent portion in a second direction intersecting the first direction. The terminal part is shaped to be bent in the plate thickness direction at the bent portion.
[0003] In contrast, Fig.13 As shown, a terminal part 3 bent in the plate width direction at the bending portion 2 can also be used. The terminal part 3 has a pair of first side wall parts 5 protruding from both ends of the terminal box part 4 side of the bending portion 2, and a pair of second side wall parts 7 protruding from both ends of the wire connection part 6 side of the bending portion 2. For forming reasons, the first side wall part 5 and the second side wall part 7 are cut off at the inner and outer corners 8 of the bending portion 2. Here, for example, if a load is applied to the wire connection part 6 from above, the terminal part 3 may bend along an imaginary line 9 connecting the inner and outer corners 8 of the bending portion 2. Therefore, it is desirable to strengthen the bending portion 2. The terminal parts of patent documents 2-7 have a tab structure at the peripheral portion of the opening of the terminal box part. For example, it is considered to apply these tab structures to Fig.13 The terminal part 3 shown is used to reinforce the bent portion 2. Prior art literature Patent Literature

[0010] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples. The terminal part of the present invention, (1) The terminal part is in the shape of a plate and is bent in the direction of the plate width, and comprises: a bending portion, which is arranged at the bending position; a first connecting portion, which extends from the bending portion in the first direction; a second connecting portion, which extends from the bending portion in the second direction intersecting with the first direction; a pressing portion, which protrudes from the end of the bending portion on the second connecting portion side in the plate thickness direction of the bending portion to direct the plate surface toward the first direction and the direction opposite to the first direction; and a deformation limiting portion, which protrudes from the pressing portion in the first direction and is opposite to the locking portion on the bending portion side. According to the above structure, when a load is applied to the second connecting portion, the deformation limiting portion contacts the engaging portion on the bending portion side, thereby suppressing the deformation of the bending portion. In addition, the terminal component can be assembled to an assembly object such as a housing by the operator pressing the pressing portion in the first direction. In particular, since the deformation restricting portion is shaped to protrude from the pressing portion in the first direction, the deformation restricting portion and the pressing portion are compactly assembled as an integrated protruding piece structure, and thus the structure can be prevented from becoming complicated.
[0011] (2) Preferably, the engaging portion comprises: a rising portion, which protrudes from the end of the bending portion on the first connecting portion side toward the plate thickness direction of the bending portion; a top portion, which extends from the top end of the protruding direction of the rising portion toward the second direction; and a vertical portion, which protrudes from the top end of the top in the second direction toward the bending portion side, and the engaging portion and the bending portion form a cylindrical shape. According to the above structure, since the engaging portion and the bending portion form a cylindrical structure, the rigidity of the bending portion can be improved. In particular, when a load is applied to the second connecting portion from the plate thickness direction, the top end of the protruding direction of the vertical portion contacts the plate surface of the bending portion, which can suppress the deformation of the bending portion.
[0012] (3) Preferably, the first connection portion includes a cylindrical box portion opened in the first direction, and the engaging portion is formed continuously with the box portion. According to the above configuration, the rigidity of the engagement portion can be improved, and complexity of the structure can be further avoided.
[0013] (4) Preferably, the first connection portion includes a cylindrical box portion opened in the first direction, and the engaging portion is formed separately from the box portion. According to the above structure, the engaging portion can be formed without being restricted by the shape of the box portion, so the shape freedom of the engaging portion can be increased. For example, the engaging portion is lower than the box portion, which can improve the yield.
[0014] (5) It is preferable that the deformation restricting portion is arranged to face the engaging portion in the plate thickness direction of the bent portion. According to the above configuration, when a load is applied to the second connection portion from the plate thickness direction, the deformation restricting portion comes into contact with the engaging portion, thereby suppressing deformation of the bent portion.
[0015] (6) Preferably, the vertical portion has a convex portion that protrudes in a direction opposite to the first direction, and the convex portion is arranged in an internal space formed between the pressing portion, the deformation restricting portion, and the bent portion. According to the above structure, even if a load is applied to the second connecting portion from either side in the plate thickness direction, the convex portion arranged in the internal space can contact any one of the deformation limiting portion and the bent portion, thereby further suppressing the deformation of the bent portion. In addition, not only the entire convex portion but also only a part of the convex portion can be arranged in the internal space.
[0016] (7) It is preferable that the deformation restricting portion is arranged so as to overlap with the outer surface side of the top portion. According to the above structure, when a load is applied to the second connecting portion from the plate thickness direction, the deformation of the top portion is suppressed by the deformation limiting portion. In particular, since the deformation limiting portion is in contact with the top portion for a long time in the second direction, the engagement margin between the top portion and the deformation limiting portion can be sufficiently ensured. In addition, by lowering the height of the top portion, the yield rate can be improved.
[0017] (8) It is preferable that the deformation restricting portion is arranged on the inner side of the engaging portion so as to face the inner surface of at least one of the vertical portion and the rising portion. According to the above structure, when a load is applied to the second connecting portion from the plate width direction, the deformation of the bent portion can be suppressed by the deformation limiting portion contacting the inner surface of either the vertical portion or the rising portion. In particular, it is not necessary to form a dedicated structure for locking in the engaging portion, which can further avoid structural complexity.
[0018] [Details of Embodiments of the Invention] Specific examples of the present invention are described below with reference to the drawings. The present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
[0019] <Implementation Method 1> The terminal component 10 according to the first embodiment of the present invention is integrally formed by bending a conductive metal plate or the like. Figure 1 As shown in FIG. 1 , the terminal part 10 is connected to the terminal end of the electric wire 80 and assembled to the housing 60 as an assembly object. Figure 1 and Figure 2 The outer side of the paper thickness direction and Figure 3 , Figure 4 and Figure 5 The upper side of each figure is taken as the upper side. Figure 1 and Figure 2 The left side is the front. Figure 3 The left side is the left. In each figure, arrow mark U, arrow mark F and arrow mark L represent the top, the front and the left, respectively. In addition, the front is sometimes also referred to as the first direction. The left is sometimes also referred to as the second direction. These directions are not necessarily consistent with the directions in a state where the terminal part 10 is assembled in the housing 60 and mounted on a vehicle, etc. In addition, the standards for these directions can also be applied to the later-described embodiments 2 and 3.
[0020] (case) The housing 60 is made of synthetic resin and is L-shaped when viewed from above, although not shown in detail. Figure 1 As shown, the housing 60 has a first cavity 61 extending in the front-rear direction and a second cavity 62 extending in the left-right direction and communicating with the rear end of the first cavity 61. The first cavity 61 opens at the front end surface of the housing 60 via a joint insertion port 63.
[0021] The second cavity 62 is open at the rear end face and the left end face of the housing 60. The terminal part 10 is inserted into the first cavity 61 and the second cavity 62 from the rear and assembled to the housing 60. After the terminal part 10 is assembled, a cover (not shown) is installed on the housing 60 from the rear. The rear end opening of the second cavity 62 is closed by the cover. In addition, a ferrite core (not shown) is installed on the terminal part 10 before being assembled to the housing 60.
[0022] (Terminal parts) like Figure 2As shown, the terminal part 10 is L-shaped when viewed from above and is bent in the plate width direction. The terminal part 10 has: a bending portion 11, which is located at a bending position in the middle of the length direction; a first connecting portion 12, which extends from the bending portion 11 in the first direction; and a second connecting portion 13, which extends from the bending portion 11 in the second direction. The bending portion 11 is in a rectangular flat plate shape when viewed from above and is formed flat along the front-back direction and the left-right direction.
[0023] like Figure 4 and Figure 5 As shown in FIG. 1 , the first connecting portion 12 has a box portion 14 in a square tube shape. The box portion 14 is open in the front-to-back direction. However, the rear open surface of the box portion 14 is partially covered by the pressing portion 31 and the deformation limiting portion 32 described later. The lower wall of the box portion 14 is connected to the front end of the bending portion 11 without a step. Figure 2 As shown in FIG. 1 , an elastic contact piece 15 is disposed inside the box portion 14. The elastic contact piece 15 is in a mountain shape extending in the front-rear direction and can be elastically deformed with the front end portion connected to the left wall of the box portion 14 (specifically, the inner wall of the left inner and outer double walls) as a fulcrum. Figure 3 As shown, a rib portion 16 bent toward the elastic contact piece 15 is formed on the right wall of the box portion 14 .
[0024] The first connection portion 12 is inserted into the first cavity 61 from the rear of the housing 60. When the housing 60 is mated with a not-shown counterpart housing, a not-shown tab-shaped counterpart terminal component mounted on the counterpart housing is inserted into the inner side of the box portion 14 from the tab insertion port 63. The counterpart terminal component is sandwiched between the elastic contact piece 15 and the reinforcing rib portion 16 and is electrically connected to the terminal component 10.
[0025] like Figure 2 As shown, the second connecting portion 13 comprises: a base 17 connected to the left end of the bent portion 11 without a step; a pair of wire barrel pieces 18 rising from the front and rear ends of the base 17 opposite to each other; and a pair of insulating barrel pieces 19 rising from the front and rear ends of the base 17 opposite to each other at a position to the left of each wire barrel piece 18. Figure 1 As shown, each wire barrel piece 18 is bent by a crimping jig (not shown) to sandwich the core wire portion 81 of the wire 80 between the base 17 and the wire 80, thereby being electrically connected to the wire 80. Each insulating barrel piece 19 is also bent by a crimping jig (not shown) to sandwich the insulating sheath 82 of the wire 80 between the base 17 and the wire 80, thereby being mechanically connected to the wire 80.
[0026] like Figure 2 As shown, the second connecting portion 13 has a pair of side walls 21 at positions between each insulating barrel piece 19 and each wire barrel piece 18 and at positions to the right of each wire barrel piece 18 in the left-right direction, and each pair of side walls 21 stands oppositely from the front and rear ends of the base 17. The standing dimensions of each side wall 21 are smaller than the standing dimensions of each wire barrel piece 18 and each insulating barrel piece 19.
[0027] like Figure 3 As shown, the terminal part 10 has: a rising portion 22 protruding upward from the right end of the bent portion 11; a top portion 23 extending from the upper end of the rising portion 22 in the second direction; and a vertical portion 24 protruding downward from the left end of the top portion 23. The rising portion 22, the top portion 23 and the vertical portion 24 constitute an engaging portion 25 that can engage with a deformation limiting portion 32 described later.
[0028] like Figure 5 As shown, the upright portion 22 is a longitudinal wall along the front-to-back direction and the up-down direction, and the front end is connected to the wall on the right side of the box portion 14 without a step. The top portion 23 is a transverse wall along the front-to-back direction and the left-right direction, and the front end is connected to the wall on the upper side of the box portion 14 without a step. In addition, the top portion 23 is bridged between the upper ends of the upright portion 22 and the vertical portion 24, and is arranged parallel to the bent portion 11.
[0029] like Figure 4 As shown, the vertical portion 24 is a longitudinal wall along the front-to-back direction and the up-down direction, and the front end is connected to the left wall of the box portion 14 (specifically, the inner wall of the left inner and outer double walls) without a step. In addition, the vertical portion 24 is arranged parallel to the rising portion 22. The lower end of the vertical portion 24 is close to the upper surface of the bent portion 11 and is arranged along the front-to-back direction.
[0030] The outer surface (left side surface) of the box portion 14 connected to the vertical portion 24 is partially covered by the extended side wall 26. The extended side wall 26 is connected to the side wall 21 of the second connection portion 13 via a curved wall 27 formed at the inner corner of the bent portion 11.
[0031] like Figure 4 As shown, the rear end of the engaging portion 25 has a recessed portion 28 in a shape cut between the right end of the top portion 23 and the lower end of the vertical portion 24. The lower end of the rear end of the vertical portion 24 is formed as a convex portion 29 that protrudes relatively backward relative to the recessed portion 28. The lower surface of the convex portion 29 is a part of the lower end of the vertical portion 24 and is arranged in the front-to-back direction. The upper surface of the convex portion 29 is a part of the inner surface of the recessed portion 28 and is also arranged in the front-to-back direction.
[0032] In addition, if Figure 5As shown, the terminal part 10 has: a pressing portion 31 protruding upward from the end portion on the rear side of the bending portion 11; and a deformation limiting portion 32 protruding from the upper end of the pressing portion 31 toward the first direction. The pressing portion 31 is a vertical wall along the left-right direction and the up-down direction, and the left end is connected to the side wall 21 of the second connecting portion 13. The right end of the pressing portion 31 is located to the left of the vertical portion 22 in the left-right direction. Among the front surface and the rear surface of the plate surface serving as the pressing portion 31, the front surface is arranged to face the first direction, and the rear surface is arranged to face the direction opposite to the first direction. The rear surface of the pressing portion 31 is continuous with the rear surface of the side wall 21 without a step, and is configured as a pressing surface 33 that is pressed when the first connecting portion 12 is inserted into the first cavity 61.
[0033] The deformation restricting portion 32 is formed by bending forward from the upper end of the pressing portion 31 and has the same width in the left-right direction as the pressing portion 31. A notch 34 is formed between the upper left end of the pressing portion 31 and the upper right end of the side wall 21.
[0034] In the case of the first embodiment, the protruding dimension of the deformation limiting portion 32 to the front is set to be smaller than the protruding dimension of the convex portion 29. However, contrary to the first embodiment, the protruding dimension of the deformation limiting portion 32 to the front is set to be larger than the protruding dimension of the convex portion 29. By making the protruding dimensions of the deformation limiting portion 32 and the convex portion 29 different from each other, the formability can be improved. Furthermore, the protruding dimension of the deformation limiting portion 32 to the front can also be the same as the protruding dimension of the convex portion 29, thereby improving the strength of the bending portion 11 and the engaging portion 25. The deformation limiting portion 32 is opposite to the upper surface of the bending portion 11. Figure 4 As shown in the figure, an internal space 35 open to the first direction is formed between the bent portion 11 and the pressing portion 31. The convex portion 29 enters from the front and is arranged at the left end of the internal space 35. Here, the upper surface of the convex portion 29 is arranged opposite to the lower surface of the left end of the deformation restricting portion 32 so as to be in contact (including contact). The lower surface of the convex portion 29 is arranged opposite to the upper surface of the bent portion 11 so as to be in contact.
[0035] (effect) The first connecting portion 12 is inserted into the first cavity 61 by pressing the pressing surface 33 of the pressing portion 31 with a finger (not shown) and pressing the pressing portion 31 from the rear (see FIG. 1 ). Figure 1 ). At the same time, the second connection portion 13 is also inserted into the second cavity 62, and the terminal component 10 is assembled to the housing 60. Then, a cover (not shown) is mounted on the housing 60. Thus, the terminal component 10 is accommodated in the housing 60 in a state of being prevented from coming off.
[0036] However, during the crimping process of the electric wire 80 or due to vibration of the electric wire 80 after crimping, a load (external force) is applied to the second connecting portion 13 , and this load is transmitted to the bent portion 11 , sometimes generating a large stress in the bent portion 11 .
[0037] Assuming that a load is applied to the second connecting portion 13 from above (above the plate thickness direction of the base 17), the left end of the deformation limiting portion 32 contacts the upper surface of the protrusion 29, and the downward displacement (deformation) of the deformation limiting portion 32 is restricted, and the downward displacement of the bent portion 11 continuous with the deformation limiting portion 32 is also restricted (refer to Figure 4 ). In addition, when a load is applied to the second connecting portion 13 from below (below the plate thickness direction of the base 17), the bent portion 11 contacts the lower end of the convex portion 29 and the vertical portion 24, and the upward displacement of the bent portion 11 is restricted. Furthermore, when a load is applied to the second connecting portion 13 from the rear (rear of the plate width direction of the base 17), the left end of the deformation limiting portion 32 contacts the inner surface of the recess 28 (the rear end of the vertical portion 24), and the extended side wall 26 contacts the outer surface of the box portion 14 connected to the vertical portion 24, and the forward displacement of the second connecting portion 13 is also restricted.
[0038] Thus, according to the first embodiment, the terminal component 10 can be assembled to the housing 60 by pressing the pressing portion 31 from the rear. In addition, when a load is applied to the second connecting portion 13, the deformation limiting portion 32 contacts the convex portion 29 of the engaging portion 25, etc., and thus the deformation of the bent portion 11 can be suppressed. In particular, in the case of the first embodiment, since the deformation limiting portion 32 is a shape continuous from the pressing portion 31, and the deformation limiting portion 32 and the pressing portion 31 form an integral protruding piece structure, the structure can be simplified compared to the case where the deformation limiting portion 32 and the pressing portion 31 are formed separately.
[0039] In addition, since the engagement portion 25 and the bent portion 11 form a tubular structure, the rigidity of the bent portion 11 itself can be improved. Furthermore, since the engagement portion 25 is continuous from the box portion 14 of the first connecting portion 12, the rigidity of the engagement portion 25 itself can be improved.
[0040] Furthermore, by configuring the protrusion 29 in the internal space 35 formed between the pressing portion 31, the deformation limiting portion 32 and the bending portion 11, even if a load is applied to the second connecting portion 13 from either side in the plate thickness direction, the protrusion 29 configured in the internal space 35 can contact either the deformation limiting portion 32 or the bending portion 11, thereby further suppressing the deformation of the bending portion 11.
[0041] <Implementation Method 2> like Figures 6 to 9As shown, the shapes of the bending portion 11 and the peripheral portions of the bending portion 11 of the terminal part 10A of the second embodiment of the present invention are different from those of the first embodiment. The rest is the same as the first embodiment, and the same reference numerals are given to the same or corresponding parts as the first embodiment, and repeated descriptions are appropriately omitted.
[0042] like Fig. 9 As shown, the bent portion 11 has a receiving portion 36 in the central portion in the plate width direction, and the receiving portion 36 is a shape bent upward by stamping. The receiving portion 36 is L-shaped when viewed from above, and has a portion extending in the front-to-back direction and a portion extending in the left-to-right direction. The upper surface of the receiving portion 36 is formed flat along the front-to-back direction and the left-to-right direction.
[0043] Similar to the first embodiment, an engaging portion 25 composed of a rising portion 22, a top portion 23 and a vertical portion 24 is formed above the bent portion 11. Figure 7 As shown, the lower end of the vertical portion 24 is opposite to the upper surface of the receiving portion 36 in a contactable manner along the front-to-back direction. Figure 8 and Fig. 9 As shown, the rear end of the rising portion 22 has a notch-shaped recess 37 in a portion other than the upper end. Unlike the first embodiment, the engaging portion 25 is not formed with the recess 28 and the projection 29 .
[0044] Similar to the first embodiment, the terminal part 10A has: a pressing portion 31 protruding upward from the end portion on the rear side of the bending portion 11; and a deformation limiting portion 32 protruding from the upper end of the pressing portion 31 toward the first direction. The upper and lower dimensions of the pressing portion 31 (the protruding dimension protruding from the bending portion 11) are set larger than the upper and lower dimensions of the first embodiment. The upper end position of the pressing portion 31 (the height position of the deformation limiting portion 32) corresponds to the upper end position of the recess 37. In the case of the second embodiment, since the upper end position of the pressing portion 31 is relatively high, a structure equivalent to the cutout portion 34 of the first embodiment is not formed between the pressing portion 31 and the side wall 21, and the right end of the side wall 21 is connected to the pressing portion 31 as a whole.
[0045] The front-to-back dimension of the deformation restricting portion 32 (the protruding dimension from the pressing portion 31) is set larger than the front-to-back dimension of the embodiment 1. The deformation restricting portion 32 enters and is arranged inside the engaging portion 25 surrounded by the rising portion 22, the top portion 23 and the vertical portion 24. Figure 8 As shown, the left end of the deformation restricting portion 32 is disposed opposite to the inner surface (right side surface) of the upper portion of the vertical portion 24 so as to be contactable. The right end of the deformation restricting portion 32 is disposed opposite to the inner surface of the upper portion of the rising portion 22 with a gap therebetween.
[0046] When the terminal part 10A is assembled to the housing 60, the pressing surface 33 of the pressing portion 31 is pressed from the rear, as in the first embodiment. In the case of the second embodiment, the area of the pressing surface 33 is ensured to be wider than that of the first embodiment. Therefore, the assembly operation of the terminal part 10A can be stabilized.
[0047] Assuming that a load is applied to the second connecting portion 13 from the front (front of the base 17 in the plate width direction), the left end of the deformation limiting portion 32 contacts the inner surface of the upper portion of the vertical portion 24, and the displacement of the deformation limiting portion 32 in the second direction and rearward is restricted, and the displacement of the bending portion 11 continuous with the deformation limiting portion 32 in the second direction and rearward is also restricted.
[0048] Thus, according to the second embodiment, when a load is applied to the second connecting portion 13 from the front, the deformation limiting portion 32 contacts the inner surface of the vertical portion 24, thereby suppressing the deformation of the bent portion 11. In particular, it is not necessary to form a dedicated structure for locking in the engaging portion 25, thereby further avoiding the complication of the structure. Furthermore, according to the second embodiment, when a load is applied to the second connecting portion 13 from below (below the plate thickness direction of the base 17), the receiving portion 36 contacts the lower end of the vertical portion 24, and the upward displacement of the bent portion 11 is limited.
[0049] <Implementation Method 3> like Figures 10 to 12 As shown, the shapes of the bent portion 11 and the peripheral portions of the bent portion 11 of the terminal part 10B of the third embodiment of the present invention are different from those of the first embodiment. The rest is the same as the first embodiment, and the same reference numerals are given to the same or corresponding parts as the first embodiment, and repeated descriptions are appropriately omitted.
[0050] like Fig.12 As shown, similarly to the second embodiment, the bent portion 11 has an L-shaped receiving portion 36 bent upward. Similar to the first embodiment, an engaging portion 25 composed of a rising portion 22, a top portion 23, and a vertical portion 24 is formed above the bent portion 11. The vertical dimension of the rising portion 22 (the protruding dimension protruding from the bent portion 11) and the vertical dimension of the vertical portion 24 (the protruding dimension protruding from the top portion 23) are set smaller than the vertical dimension of the first embodiment.
[0051] The engaging portion 25 is separated from the box portion 14 of the first connecting portion 12. Fig.11 As shown, the top 23 and the vertical portion 24 each have a front end at a position closer to the rear of the box portion 14. Fig.12 As shown, a notch 38 is provided between the front end of the upper portion of the rising portion 22 and the right wall of the box portion 14. Fig.11As shown, the outer surface (left side) of the front part of the vertical part 24 is arranged opposite to the rear end extension 39 of the left side wall (more specifically, the outer wall of the left inner and outer double walls) of the box part 14 so as to be contactable. The lower end of the vertical part 24 is arranged opposite to the upper surface of the receiving part 36 in the front-to-back direction so as to be contactable.
[0052] like Fig.12 As shown, the rear end of the engagement portion 25 has a recessed portion 41 in a shape notched from the left end of the top portion 23 to the rising portion 22. Unlike the first embodiment, the engagement portion 25 is not formed with the recessed portion 28 and the convex portion 29.
[0053] As in the first embodiment, the terminal part 10B includes: a pressing portion 31 protruding upward from the rear end of the bent portion 11; and a deformation limiting portion 32 protruding from the upper end of the pressing portion 31 in the first direction. The pressing portion 31 and the deformation limiting portion 32 are formed with the same width in the left-right direction, and have a left end at the same position as or close to the left side surface of the engaging portion 25 (see Fig.10 ), and has a right end to the left of the right side surface of the rising portion 22. A structure equivalent to the cutout portion 34 of the first embodiment is not formed between the pressing portion 31 and the side wall 21, and the right end of the side wall 21 is connected to the pressing portion 31 as a whole.
[0054] like Fig.11 As shown, the vertical dimension of the pressing portion 31 (the protruding dimension protruding from the bending portion 11) is set larger than the vertical dimension of the engaging portion 25. The front-to-back dimension of the deformation limiting portion 32 (the protruding dimension protruding from the pressing portion 31) is set larger than the front-to-back dimension of the first embodiment. The deformation limiting portion 32 is arranged to be contactable with the upper surface of the top 23 in the left-right direction in a manner covering the rear upper surface of the top 23 of the engaging portion 25. More specifically, the deformation limiting portion 32 is arranged to overlap with the outer surface side of the top 23. The pressing portion 31 is arranged to be contactable with the end portion on the left side of the top 23 at the rear end of the engaging portion 25 and the vertical portion 24.
[0055] When the terminal fitting 10B is assembled to the housing 60 , the pressing surface 33 of the pressing portion 31 is pressed from the rear, similarly to the first embodiment. Assuming that a load is applied to the second connecting portion 13 from above (above the plate thickness direction of the base 17), the deformation limiting portion 32 contacts the upper surface (outer surface) of the top portion 23, and the displacement of the deformation limiting portion 32 downward is restricted, and the displacement of the bent portion 11 continuous with the deformation limiting portion 32 downward is also restricted. In particular, in the case of the third embodiment, the deformation limiting portion 32 can contact the top portion 23 over the entire width of the deformation limiting portion 32 in the left-right direction, so that the engagement margin between the top portion 23 and the deformation limiting portion 32 can be fully ensured. In addition, since the engaging portion 25 is formed separately from the box portion 14, the engaging portion 25 can be formed without being restricted by the shape of the box portion 14. In the case of the third embodiment, since the engaging portion 25 is formed lower than the box portion 14, the yield rate can be improved.
[0056] In addition, if a load is applied to the second connecting portion 13 from the rear (the rear of the plate width direction of the base 17), the pressing portion 31 contacts the rear end of the engaging portion 25, the pressing portion 31 is restricted from being displaced forward, and the bending portion 11 continuous with the pressing portion 31 is also restricted from being displaced forward. Further, if a load is applied to the second connecting portion 13 from the front (the front of the plate width direction of the substrate), the vertical portion 24 contacts the rear end extension portion 39 of the box portion 14, the engaging portion 25 including the vertical portion 24 is restricted from being displaced backward, and the bending portion 11 continuous with the engaging portion 25 is also restricted from being displaced backward. Further, according to the third embodiment, when a load is applied to the second restricting portion from the bottom (the bottom of the plate thickness direction of the base 17), the receiving portion 36 contacts the lower end of the vertical portion 24, and the bending portion 11 is restricted from being displaced upward.
[0057] [Other embodiments of the present invention] It should be considered that the above-mentioned Embodiments 1 to 3 disclosed this time are illustrative and non-restrictive in all aspects. In the above-mentioned embodiments 1-3, the first direction is defined as the front and the second direction is defined as the left. In contrast, in other embodiments, the first direction may be defined as a direction other than the front and the second direction may be defined as a direction other than the left and intersecting the first direction. In the case of the above-mentioned Embodiments 1-3, the first direction and the second direction are orthogonal to each other. On the other hand, in the case of other embodiments, the first direction and the second direction only need to intersect each other and do not need to be orthogonal. In the case of the above-mentioned embodiments 1-3, the engaging portion is formed by the rising portion, the top portion and the vertical portion. In contrast, in the case of other embodiments, the engaging portion may also be a structure without a vertical portion, where the top portion overlaps the bent portion without a gap and forms a double-walled structure together with the bent portion. In the case of the second embodiment, the left end of the deformation limiting portion is disposed opposite to the inner surface of the vertical portion so as to be in contact with each other. In contrast, in the case of other embodiments, the right end of the deformation limiting portion may be disposed opposite to the inner surface of the upright portion so as to be in contact with each other. Alternatively, the left and right ends of the deformation limiting portion may be disposed opposite to the inner surface of the vertical portion and the inner surface of the upright portion, respectively.
