Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a shielded connector. [Background technology]
[0002] The connector described in Patent Document 1 includes an inner conductor, an outer conductor, a housing, and a plate-shaped conductive member. The outer conductor has a tubular portion electrically connected to a mating outer conductor. The plate-shaped conductive member extends from the inside to the outside of the housing and has a first connection portion electrically connected to a grounding member outside the housing and a second connection portion electrically connected to the tubular portion inside the housing. Patent Document 2 discloses a connector in which a shell-side ground connection portion is provided on a shell that covers the housing. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Publication No. 2024-033887 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-207411 Summary of the Invention [Problem to be solved by the invention]
[0004] As shown in FIG. 10 of the present disclosure, the ground connection member 1 (corresponding to the plate-shaped conductive member in Patent Document 1 and the shell-side ground connection portion in Patent Document 2) may extend upward from a holding portion 5 held by the housing 2, diagonally leftward from the housing 2, so that the upper end of the ground connection member 1 contacts the grounding member 3 from below. The holding portion 5 has a locking portion (not shown) that is locked to the housing 2. Here, the ground connection member 1 receives a force in the direction of rotation (see arrow B in FIG. 10 ) away from the housing 2 due to contact with the grounding member 3. At this time, the holding portion 5 serves as the center of rotation of the ground connection member 1. As a result, a large load is applied to the holding portion 5, which may cause the locking position of the locking portion to shift relative to the housing 2, weakening the locking force of the ground connection member 1. If the locking force of the ground connection member 1 weakens, the shielding performance of the connector 4 may be reduced.
[0005] An object of the present disclosure is to provide a shielded connector that can ensure a locking force when a connection member that contacts a ground is locked to a housing. [Means for solving the problem]
[0006] The shielded connector of the present disclosure comprises: an insulating housing; a conductive outer conductor held in the housing; a conductive plate-shaped connecting member connected to the outer conductor, The housing has a groove that opens to one side surface of the housing, The connecting member is a base portion disposed along one side surface of the housing; an elastically deformable extension portion extending from a connecting portion connected to the base portion to a contact portion that contacts an external ground; a locking piece bent from the base and placed in the groove, the extension portion is inclined in one direction away from the one side surface of the housing toward the contact portion, The locking piece has a plurality of locking projections that are locked to the inner surface of the groove. [Effects of the Invention]
[0007] According to the present disclosure, it is possible to provide a shielded connector that can ensure a locking force when a connection member that contacts a ground is locked in a housing. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The shielded connector of the present disclosure comprises: (1) A shielded connector comprising an insulating housing, a conductive outer conductor held in the housing, and a conductive plate-shaped connecting member connected to the outer conductor, wherein the housing has a groove opening to one side of the housing, and the connecting member has a base arranged with its plate surface aligned along one side of the housing, an elastically deformable extension extending from a connecting portion connected to the base to a contact portion that contacts an external ground, and a locking piece bent from the base and arranged in the groove, the extension inclined in one direction away from the one side of the housing toward the contact portion, and the locking piece has a plurality of locking protrusions that lock onto the inner surface of the groove.
[0010] According to the above (1), even if a force is applied to the connection member in a rotational direction away from one side surface of the housing due to contact between the connection member and an external ground, the locking force of the multiple locking protrusions can resist the force, thereby preventing the connection member from rotating.
[0011] (2) In the shielded connector described in (1) above, it is preferable that some of the multiple locking protrusions protrude in one direction in the thickness direction of the locking piece, and other parts protrude in the other direction in the thickness direction of the locking piece.
[0012] According to (2) above, when the locking pieces are inserted into the grooves, some of the locking protrusions are locked onto one surface of the inner surface of the groove, and the other of the locking protrusions are locked onto the other surface of the inner surface of the groove. This prevents the sliding traces (movement trajectories) of the locking protrusions of the one and the other parts from overlapping on the inner surface of the groove, and allows each locking protrusion to be stably held on the inner surface of the groove.
[0013] (3) In the shielded connector described in (2) above, it is preferable that the multiple locking protrusions are arranged on the plate surface of the locking piece in a line extending in the bending direction of the locking piece.
[0014] According to (3) above, the plate width of the locking piece (the width dimension of the plate surface of the locking piece in the direction perpendicular to the bending direction of the locking piece) can be reduced, which allows for miniaturization of the shielded connector.
[0015] (4) In the shielded connector described in (1) above, it is preferable that the width direction of the base is oriented in the width direction of one side of the housing, the grooves are provided at both ends of the width direction of one side of the housing, the locking pieces are bent in pairs from both ends of the base in the width direction, and the base is gradually formed wider from the connecting portion toward the locking pieces.
[0016] According to the above feature (4), when the connecting member comes into contact with an external ground, the stress generated at the base can be dispersed to the wide portion extending from the coupling portion toward the locking piece, making it more difficult for the connecting member to rotate in the direction away from the side surface of the housing.
[0017] (5) In the shielded connector described in (1) above, the extension portion has a root portion including the connecting portion, a tip portion including the contact portion, and an intermediate portion arranged between the root portion and the tip portion, and it is preferable that the plate width dimension of the root portion is larger than the plate width dimension of the tip portion, and that the intermediate portion is gradually narrower from the root portion toward the tip portion.
[0018] According to the above (5), since the plate width dimension of the root portion is larger than that of the tip portion, the strength of the root portion can be improved compared to when the plate width dimensions of the root portion and the tip portion are the same. Also, since the plate width dimension of the tip portion is smaller than that of the root portion, the elastic force of the connecting member can be reduced compared to when the plate width dimensions of the root portion and the tip portion are the same. Also, since the intermediate portion is gradually narrowed from the root portion to the tip portion, stress generated in the intermediate portion can be dispersed.
[0019] (6) In the shielded connector described in any one of (1) to (5) above, it is preferable that the extension portion extends linearly from the connecting portion to the contact portion.
[0020] According to the above (6), the processing steps for the connection member can be easily simplified, thereby reducing the cost of the shielded connector.
[0021] [Details of the embodiments of the present disclosure] Specific examples of embodiments of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.
[0022] [Embodiment 1] A specific example of the first embodiment of the present disclosure will be described with reference to FIGS. 1 to 9. As shown in FIG. 1, the shielded connector 10 includes an inner conductor 11, a dielectric 12, an outer conductor 13, a housing 14, and a connecting member 15. As shown in FIG. 2, the connecting member 15 is electrically connected to an external ground 16. The ground 16 is a metal housing. The shielded connector 10 is a board connector mounted on a circuit board 17. In each figure, the X direction, Y direction, and Z direction represent the front, right, and upward, respectively. In the first embodiment, the upward direction is the side where a mating connector 34 is mated with the shielded connector 10. The left-right direction coincides with the width direction of the housing 14. Note that the reference directions for these directions do not necessarily coincide with the reference directions when the shielded connector 10 is mounted on a vehicle or the like (not shown).
[0023] (Inner conductor 11) As shown in FIG. 1, the inner conductor 11 is a conductive metal plate and has a tab or pin shape. In the first embodiment, the shielded connector 10 includes two inner conductors 11 of the same shape. Each inner conductor 11 has a mating connection portion 18, a relay portion 19, and a board connection portion 20. The mating connection portion 18 extends in the vertical direction. As shown in FIG. 2, the lower portion of the mating connection portion 18 is held by the dielectric 12. The upper portion of the mating connection portion 18 protrudes above the dielectric 12. The relay portion 19 is disposed between the mating connection portion 18 and the board connection portion 20. The relay portion 19 extends from the lower end of the mating connection portion 18 at an inclined downward and forward. The board connection portion 20 extends forward from the lower end of the relay portion 19. The board connection portion 20 is disposed along the upper surface of the circuit board 17 and is connected to a conductive portion of the circuit board 17 by soldering.
[0024] (Dielectric 12) The dielectric 12 is made of synthetic resin. As shown in FIG. 2, the dielectric 12 has an L-shaped block shape in a side view. The dielectric 12 has a terminal mounting portion 21 and a terminal lead-out portion 22. The terminal mounting portion 21 has a shape that extends in the vertical direction. The terminal lead-out portion 22 is connected to the lower end of the terminal mounting portion 21 and extends forward.
[0025] The terminal mounting portion 21 has a plurality of mounting holes 23. Each mounting hole 23 penetrates in the vertical direction. In the case of the first embodiment, two mounting holes 23 are provided spaced apart in the horizontal direction. The mating connection portion 18 of the inner conductor 11 is inserted into the mounting holes 23 from below. The lower part of the mating connection portion 18 is press-fitted into the mounting holes 23 and held therein.
[0026] (Outer conductor 13) The outer conductor 13 is conductive and formed by die-casting. As shown in Fig. 2, a dielectric 12 with an inner conductor 11 attached thereto is disposed inside the outer conductor 13. The outer conductor 13 has, from bottom to top, a bottom portion 24, a flange portion 25, and a cylindrical portion 26, in that order.
[0027] 3, flange 25 is flat and has a rectangular outer shape when viewed from the bottom. Bottom 24 protrudes downward from flange 25. Bottom 24 has a gate-like shape when viewed from the bottom, and is open forward and downward.
[0028] As shown in Fig. 4, the tubular portion 26 protrudes upward from the flange portion 25. The tubular portion 26 has a rectangular cylindrical shape with rounded corners and is open upward. As shown in Fig. 2, the outer conductor 13 has an insertion hole 27 that passes through in the vertical direction from the flange portion 25 to the tubular portion 26.
[0029] The terminal mounting portion 21 of the dielectric 12 is inserted into the insertion hole 27 from below the outer conductor 13 through the inside of the bottom portion 24. The upper end surface of the terminal mounting portion 21 is arranged in the vertical middle of the insertion hole 27 of the tubular portion 26. The upper end of the mating connection portion 18 of the inner conductor 11 protrudes from the upper end surface of the terminal mounting portion 21 and is arranged in the insertion hole 27 of the tubular portion 26. The relay portion 19 of the inner conductor 11 protrudes downward from the insertion hole 27 of the flange portion 25 and is arranged inside the bottom portion 24 except for its lower end. The board connection portion 20 of the inner conductor 11 is arranged forward from the inside of the bottom portion 24 and is connected to the circuit board 17. The terminal pull-out portion 22 of the dielectric 12 is housed inside the bottom portion 24.
[0030] 4, a plurality of protrusions 28 are formed on the upper surface of the flange 25. The protrusions 28 are arranged at intervals in the circumferential direction on the outer peripheral surface of the tubular portion 26. The protrusions 28 are connected to the outer peripheral surface of the tubular portion 26 while extending in the up-down direction. The protrusions 28 can be engaged with recesses 29 of the housing 14, which will be described later.
[0031] A plurality of board mounting portions 30 are formed to protrude from the underside of the flange 25. As shown in FIG. 3, each board mounting portion 30 is cylindrical, and five board mounting portions 30 are formed in total here. Four of the board mounting portions 30 are connected to the four corners of the bottom 24 from the underside of the flange 25 to a position partway down, and the remaining one is connected to the left-right middle part of the rear surface to the same position. As shown in FIG. 2, the lower end of each board mounting portion 30 (the portion below the bottom 24) is positioned and inserted into a plurality of mounting holes 31 provided in the circuit board 17.
[0032] (Housing 14) The housing 14 is made of synthetic resin and has a rectangular cylindrical shape, as shown in Fig. 5. The housing 14 has a bottom wall portion 32 and a fitting portion 33.
[0033] The bottom wall 32 has a rectangular plate shape when viewed from the bottom, and constitutes the lower end of the housing 14. The mating portion 33 protrudes upward from the outer peripheral edge of the upper surface of the bottom wall 32. A mating connector 34 is mated with the mating portion 33. As shown in FIG. 2 , the housing 14 has an insertion hole 35 that extends vertically from the bottom wall 32 to the mating portion 33. The tubular portion 26 of the outer conductor 13 is inserted into the insertion hole 35 from below.
[0034] As shown in Fig. 5, a plurality of recesses 29 are formed on the lower surface of the bottom wall portion 32. Each recess 29 is provided corresponding to each protrusion 28. Each recess 29 opens to the lower surface of the bottom wall portion 32 and also opens to the inner circumferential surface of the insertion hole 35. Each protrusion 28 of the outer conductor 13 is inserted into and locked in each recess 29. This connects the outer conductor 13 and the housing 14 in a state where separation in the vertical direction is suppressed.
[0035] A pair of protrusions 36 are formed to protrude from a rear surface 58 (corresponding to one side surface in the present disclosure) of the housing 14. Each protrusion 36 is shaped like a rectangular pillar. The protrusions 36 are arranged at the lower end of the rear surface 58 with a gap between them in the left-right direction. Each protrusion 36 is fitted into a receiving portion 37 of the connecting member 15, which will be described later.
[0036] A pair of grooves 38 are formed at the lower end of the rear surface 58. Each groove 38 is located on the rear surface 58, outward of each protrusion 36 in the left-right direction. Each groove 38 is slit-shaped. The width of each groove 38 is determined by the distance between the inner surfaces facing each other in the left-right direction. Each groove 38 extends in the front-rear direction and opens to the rear surface 58 and also to the lower surface of the bottom wall portion 32. The inner surfaces of each groove 38 each have a first surface 39, which is the inner wall surface in the left-right direction, and a second surface 40, which is the outer wall surface in the left-right direction. The first surface 39 and the second surface 40 face each other in the left-right direction. When the outer conductor 13 and the housing 14 are connected, the lower opening of each groove 38 is closed by the flange portion 25. A locking piece 41 (described later) of the connection member 15 is inserted into the groove 38.
[0037] (connecting member 15) The connecting member 15 is made of a conductive metal plate. As shown in Fig. 6, the connecting member 15 has a base 42, a plurality of elastically deformable extensions 43, an outer conductor connecting portion 44, and a plurality of locking pieces 41.
[0038] The base 42 has a flat plate shape with its width oriented in the left-right direction. As shown in Fig. 3, the base 42 is disposed along the rear surface 58 of the housing 14 so as to cover the lower end of the rear surface 58. The plate width of the base 42 (the left-right dimension of the base 42) is smaller than the width of the rear surface 58 of the housing 14 (the left-right dimension of the rear surface of the housing 14).
[0039] As shown in Fig. 6, the base 42 has a pair of end portions 45 located at both left and right ends of the base 42, and a central portion 46 located at the left-right center of the base 42. The vertical dimension of the central portion 46 is larger than the vertical dimension of the end portions 45. The end portion 45 has a pair of left and right receiving portions 37. Each receiving portion 37 is located on the left and right inner sides of the end portion 45 and has a concave opening at the lower end of the end portion 45. As shown in Fig. 3, each protrusion 36 of the housing 14 is fitted into each receiving portion 37 from below.
[0040] As shown in Fig. 6, the outer conductor connecting portion 44 has its plate surface facing the vertical direction. The outer conductor connecting portion 44 is connected to the lower end of the central portion 46. Specifically, as shown in Fig. 2, the outer conductor connecting portion 44 has an outer conductor contact portion 47 that bends upward in a mountain shape and extends forward in side view. The front portion of the outer conductor connecting portion 44 extends diagonally downward and forward from the outer conductor contact portion 47. The outer conductor connecting portion 44 can elastically deform in the vertical direction with the connecting portion with the central portion 46 as a fulcrum. In the case of the first embodiment, the outer conductor connecting portion 44 contacts the lower surface of the flange portion 25 of the outer conductor 13. This electrically connects the outer conductor connecting portion 44 to the outer conductor 13.
[0041] 7, the base 42 has a pair of inclined portions 48 that taper upward on the left and right edges of each end 45. The base 42 is formed so that its width gradually increases from top to bottom in the vertical range corresponding to each inclined portion 48.
[0042] 6, each locking piece 41 is bent (protrudes) forward from a portion below the inclined portion 48 on the left and right edges of each end 45. The thickness direction of the locking piece 41 faces the left-right direction.
[0043] The locking piece 41 also has a plurality of locking protrusions 49 that protrude in the left-right direction, i.e., the thickness direction, from the plate surfaces (left and right surfaces, front and back surfaces) of the locking piece 41. Each locking protrusion 49 is formed by bending the plate surface of the locking piece 41, for example, by punching or hammering, such as louvering. As shown in FIG. 8, a rear end surface 59 of each locking protrusion 49 is a plate thickness surface (extruded surface or cut-out surface) of each locking piece 41 and is arranged along the up-down direction. The outer periphery of the rear end surface 59 forms an arc shape that bulges out in the left-right direction when viewed from behind.
[0044] The amount of protrusion of each locking projection 49 in the left-right direction gradually increases from the front end toward the rear end face 59. In addition, each locking projection 49 has a triangular shape in a side view, and the dimension in the up-down direction gradually increases from the front end toward the rear end face 59.
[0045] As shown in FIG. 9, each locking piece 41 has a first locking protrusion 50 and a second locking protrusion 51 as the locking protrusions 49. The first locking protrusion 50 protrudes inward in the left-right direction of the locking piece 41 (toward the left-right center of the housing 14). The second locking protrusion 51 protrudes outward in the left-right direction of the locking piece 41 (away from the left-right center of the housing 14). As shown in FIG. 6, the first locking protrusion 50 is disposed at the front end of the locking piece 41. The second locking protrusion 51 is located rearward of the first locking protrusion 50 and at the rear end of the locking piece 41. In each locking piece 41, the top and bottom centers (tops) of the first locking protrusion 50 and the second locking protrusion 51 are aligned on a straight line in the front-rear direction.
[0046] As shown in Fig. 7, each locking piece 41 is inserted into the groove 38 of the housing 14 from the rear. As shown in Fig. 9, the first locking projection 50 bites into the first surface 39 and is locked. Similarly, the second locking projection 51 bites into the second surface 40 and is locked.
[0047] As shown in FIG. 6, the extensions 43 are arranged in three rows in the left-right direction on the connecting member 15. The plate width direction of each extension 43 faces the left-right direction. The extensions 43 are formed in a polygonal line shape that extends linearly in one direction (diagonally upward and rearward) from a connecting portion 52 (described later) to a contact portion 53, gradually moving away from a rear surface 58 of the housing 14. The connecting portion 52 is connected to the upper end of the base 42 along the left-right direction. As shown in FIG. 2, the extensions 43 are connected to the base 42 at the connecting portion 52 at an obtuse angle. The extensions 43 can elastically deform in the up-down direction with the connecting portion 52 as a fulcrum.
[0048] As shown in FIG. 6 , the extension portion 43 has a root portion 54, a tip portion 55, and an intermediate portion 56. The root portion 54 is a portion extending from the connecting portion 52. The width dimensions of the root portion 54 and the tip portion 55 are constant in the extension direction of the extension portion 43. The width dimension of the root portion 54 is larger than the width dimension of the tip portion 55. The tip portion 55 is located at the end of the extension portion 43 in the extension direction. The intermediate portion 56 is located between the root portion 54 and the tip portion 55. The width of the intermediate portion 56 gradually narrows from the root portion 54 to the tip portion 55.
[0049] The contact portion 53 is the upper end of the tip portion 55. As shown in Fig. 2, the contact portion 53 protrudes from the upper end of the tip portion 55 toward the ground 16, and the curved upper surface of the contact portion 53 contacts the lower surface of the ground 16. In the case of the first embodiment, the lower surface of the ground 16 is a horizontal plane extending in the front-rear and left-right directions.
[0050] A bent tip portion 57 is connected to the contact portion 53 of the extension portion 43. The bent tip portion 57 is the rear end of the tip portion 55, and is bent obliquely downward and rearward from the contact portion 53 to extend a short distance. The connecting member 15 has a symmetrical shape on both the left and right sides of the left-right center of the connecting member 15.
[0051] (Assembly procedure for shielded connector 10) As shown in Fig. 2, the mating connection portion 18 of the inner conductor 11 is inserted from below into the mounting hole 23 of the dielectric 12. After the inner conductor 11 is mounted, the dielectric 12 is mounted on the outer conductor 13. Specifically, the terminal mounting portion 21 of the dielectric 12 is inserted from below into the insertion hole 27 of the outer conductor 13. Furthermore, the tubular portion 26 of the outer conductor 13 is inserted from below into the insertion hole 35 of the housing 14. At this time, the upper surface of the flange portion 25 of the outer conductor 13 faces the lower surface of the bottom wall portion 32 of the housing 14.
[0052] After the outer conductor 13 and the housing 14 are assembled, as shown in FIG. 7 , the locking pieces 41 of the connecting member 15 are inserted into the grooves 38 of the housing 14 from behind, and the connecting member 15 is attached to the housing 14. During the process of inserting the locking pieces 41 into the grooves 38, the locking protrusions 49 may scrape the inner surface (first surface 39 or second surface 40) of the groove 38, leaving a trace. In the case of the first embodiment, the first locking protrusion 50 is locked to the first surface 39, and the second locking protrusion 51 is locked to the second surface 40. Therefore, the second locking protrusion 51 does not pass through a trace that may be formed on the first surface 39. Therefore, the second locking protrusion 51 is properly locked to the second surface 40.
[0053] 3, when the connecting member 15 is attached to the housing 14, the outer conductor connecting portion 44 of the connecting member 15 is disposed along the lower surface of the flange portion 25 of the outer conductor 13. The outer conductor connecting portion 44 of the connecting member 15 comes into contact with the lower surface of the flange portion 25, thereby electrically connecting the connecting member 15 to the outer conductor 13. This completes the assembly of the shielded connector 10.
[0054] (Function of connecting member 15) 2, the shielded connector 10 is placed on a circuit board 17. Furthermore, the contact portion 53 of the extension portion 43 contacts the lower surface of the ground 16 from below.
[0055] Due to a downward contact load acting on the contact portion 53, the connecting member 15 receives a force in a rotational direction (see arrow A in FIG. 2 ) away from the housing 14, with the locking piece 41 or the vicinity of the locking piece 41 as a fulcrum. As described above, the first locking projection 50 is engaged with the first surface 39 of the corresponding groove 38, and the second locking projection 51 is engaged with the second surface 40 of the corresponding groove 38 (see FIG. 9 ). Each locking piece 41 is inserted into each groove 38 on both the left and right sides of the housing 14, and each locking projection 49 is provided in pairs, for a total of four. Therefore, in the case of the first embodiment, the locking action of these multiple locking projections 49 can prevent the connecting member 15 from rotating in the direction of arrow A (see FIG. 2 ), and the base 42 can be maintained in face-to-face contact with the rear surface 58 of the housing 14. Ensuring the locking force of the connecting member 15 with respect to the housing 14 in this manner results in improved shielding performance.
[0056] 8, in the case of the first embodiment, the first locking projection 50 and the second locking projection 51 are arranged side by side on a straight line extending in the front-to-rear direction, which is the bending direction of the locking piece 41, on the plate surface of the locking piece 41 (left and right surfaces, front and back surfaces of the locking piece 41). This allows the plate width dimension of the locking piece 41 to be smaller than if the first locking projection 50 and the second locking projection 51 were arranged offset from the straight line in the plate width direction of the locking piece 41 (up and down direction of the locking piece 41). This allows the shielded connector 10 to be made smaller.
[0057] 7, in the first embodiment, the pair of inclined portions 48 are formed so as to gradually widen in the left-right direction from the coupling portion 52 downward toward the position where the locking piece 41 is located. This allows the stress generated in the base portion 42 when the connection member 15 comes into contact with the ground 16 to be dispersed along the inclined portions 48. This further prevents the connection member 15 from rotating in the direction of arrow A (see FIG. 2).
[0058] In addition, in the case of the first embodiment, as shown in Fig. 6, the width dimension of the tip portion 55 is smaller than the width dimension of the root portion 54. Therefore, the elastic force acting on the connecting member 15 can be reduced compared to when the width dimensions of the root portion 54 and the tip portion 55 are the same. The width dimension of the root portion 54 is larger than the width dimension of the tip portion 55. Therefore, the strength of the root portion 54 can be improved compared to when the width dimensions of the root portion 54 and the tip portion 55 are the same. By forming the intermediate portion 56 to gradually narrow from the root portion 54 to the tip portion 55, stress generated in the intermediate portion 56 can be dispersed.
[0059] 6, in the first embodiment, the extension portion 43 extends linearly from the coupling portion 52 to the contact portion 53. This makes it easy to simplify the processing steps of the connection member 15.
[0060] [Another embodiment of the present disclosure] The first embodiment disclosed herein should be considered to be illustrative in all respects and not restrictive. In the first embodiment, two locking projections are provided for each locking piece, whereas in other embodiments, three or more locking projections may be provided for each locking piece. In the first embodiment, the locking protrusions are formed by louver processing. However, in other embodiments, the locking protrusions are not limited to being formed by louver processing. For example, the locking protrusions may be formed by cutting and raising or embossing. In the first embodiment, the locking protrusions are configured to protrude only in the thickness direction of the locking pieces. In contrast, in other embodiments, the locking protrusions may be configured to have a mixture of locking protrusions that protrude in the thickness direction of the locking pieces and locking protrusions that protrude in the width direction of the locking pieces. In the first embodiment, the first locking projection protrudes inward in the left-right direction. The second locking projection protrudes outward in the left-right direction. In contrast, in other embodiments, the first locking projection may protrude outward in the left-right direction, and the second locking projection may protrude inward in the left-right direction. Alternatively, both the first locking projection and the second locking projection may protrude only inward or outward in the left-right direction. In the first embodiment, three extensions are arranged side by side in the left-right direction. In contrast to this, in other embodiments, two or less extensions or four or more extensions may be arranged side by side in the left-right direction. [Explanation of symbols]
