[0011] <Embodiment> Hereinafter, with reference to the drawings, the clamp locking structure and the locked portion according to the embodiment of the present invention will be described. For the convenience of explanation, as shown in each figure, "front," "back," "left," "right," "up," and "down" will be defined. The "front-back direction," "left-right direction," and "up-down direction" are perpendicular to each other. The "front-back direction" corresponds to the "first sliding direction" of the present invention, the "up-down direction" corresponds to the "second sliding direction" of the present invention, and the "left-right direction" corresponds to the "width direction" of the present invention. As shown in Figures 1 and 2, the clamp locking structure 1 comprises a wire clamp 10 and a protector 20 as a locked portion to which the wire clamp 10 is locked.

[0012] <Wire clamp 10> As shown in Fig. 3, the wire clamp 10 has a band portion 11 to which a wire (not shown) such as a wire harness is attached, a column portion 12 protruding from the band portion 11, and a flange portion 13 provided at the tip of the column portion 12. The band portion 11 is formed in a substantially strip shape that is long in the front-rear direction and is locked to the protector 20 so that the thickness direction is along the left-right direction. The band portion 11 is provided with a flange portion 14 that protrudes to the right from the front end (one end side in the longitudinal direction).

[0013] The column portion 12 has a large-diameter portion 15 and a small-diameter portion 16 having a flat cylindrical shape that protrude to the right side of the band portion 11 and are coaxially arranged. The large-diameter portion 15 has a diameter dimension D1, and the small-diameter portion 16 has a diameter dimension D2 and an axial direction dimension L2. The flange portion 13 is formed in a substantially square plate shape, and chamfered portions 17 are provided at each corner. This flange portion 13 has a width dimension W1 and a thickness dimension T3 in the front-rear direction.

[0014] <Protector 20> Returning to Figs. 1 and 2, the protector 20 has a substantially strip-shaped bottom wall 30 on which a wire is mounted, first side walls 40 and 41 erected from both sides in the left-right direction of the bottom wall 30, a pair of second side walls 50 and 50 erected from the first side wall 41, and a third side wall 60 supported by the second side walls 50 and 50. Further, the protector 20 is provided with a first slide hole 70 and a second slide hole 80 along the vertical direction and the front-rear direction, respectively, in the first side wall 40 in a substantially T shape.

[0015] The bottom wall 30 is formed in a stepped strip shape in which the bottom wall portions 31 and 32 have a step in the up-down direction. The first side wall 40 is erected upward from the right end of the bottom wall portions 31 and 32. The first side wall 41 is erected upward from the left end of the bottom wall portion 31.

[0016] As shown in Fig. 4, the second upright walls 50, 50 are erected on the outer surface 42 facing away from the first upright wall 41 of the first upright wall 40. These second upright walls 50, 50 are substantially in the shape of a prism. The second upright walls 50, 50 are arranged along the vertical direction and are arranged parallel to each other. The third upright wall 60 is in the shape of a flat plate arranged across the second upright walls 50, 50. The third upright wall 60 is arranged parallel to the first upright wall 40. The separation dimension G1 between the first upright wall 40 and the third upright wall 60 is not less than the thickness dimension T3 of the flange portion 13.

[0017] As shown in Fig. 5, the first slide hole 70 is provided extending along the vertical direction, and an opening 71 into which the column portion 12 can be inserted is provided at the upper end (open end edge). This first slide hole 70 has a wide portion 72 provided on the opening 71 side and a narrow portion 73 provided on the second slide hole 80 side. The width dimension W2 of the wide portion 72 and the width dimension W3 of the narrow portion 73 are less than the width dimension W1 of the flange portion 13, less than the diameter dimension D1 of the large diameter portion 15, and not less than the diameter dimension D2 of the small diameter portion 16.

[0018] The second slide hole 80 communicates with the lower end (bottom wall 32 side) of the first slide hole 70, that is, the narrow portion 73, and is provided extending along the front-rear direction. The vertical dimension H1 of the second slide hole 80 is less than the diameter dimension D1 of the large diameter portion 15 and not less than the diameter dimension D2 of the small diameter portion 16.

[0019] Also, the third upright wall 60 is provided so as to cover the wide portion 72 and not cover the narrow portion 73. A locking portion 90 is provided on the third upright wall 60 so as to face the wide portion 72 of the first slide hole 70. The locking portion 90 has a pair of ribs 91, 91 and a rib 92 protruding from the inner surface of the third upright wall 60. The pair of ribs 91, 91 extend along the vertical direction from the upper end to the lower end of the third upright wall 60 and are arranged side by side in the front-rear direction.

[0020] The pair of ribs 91, 91 are provided in a wedge shape, rising to the left as they extend downwards. Rib 92 is provided between the lower ends of the pair of ribs 91, 91 and runs along the front-to-back direction. The third vertical wall 60 is provided with notches 93, 93 that penetrate in the thickness direction on both the left-to-right sides of the pair of ribs 91, 91. The notches 93, 93 are provided along the vertical direction from the lower end of the third vertical wall 60 to slightly below the upper end.

[0021] Therefore, the locking portion 90 is such that the rib 92 provided at the lower end of the ribs 91, 91 can be elastically deformed in the left-right direction, with the upper end of the ribs 91, 91 acting as a fulcrum. As shown in Figure 4, the distance G2 between the rib 92 provided at the lower end of the locking portion 90 and the stopping surface 44 is set to be greater than or equal to the width W1 of the flange portion 13. A rib 43 is provided on the outer surface 42 of the second vertical wall 40 that protrudes directly below the locking portion 90, and the upper end surface of the rib 43 serves as the stopping surface 44.

[0022] <Assembly Instructions> Next, the assembly procedure for the clamp locking structure according to the embodiment of the invention will be described. First, the electric wire, such as a wire harness, is placed along the side of the band portion 11 of the electric wire clamp 10 that does not have a column portion 12, and the electric wire and the band portion 11 are wrapped together with adhesive tape or cable ties. At this time, since the band portion 11 is provided with a flange portion 14, there is no risk of the adhesive tape or cable ties falling off the band portion 11.

[0023] Next, as shown in Figure 6, the flange portion 13 of the band portion 11 is inserted between the first vertical wall 40 and the third vertical wall 60, guiding the column portion 12 of the band portion 11 into the opening 71 of the first slide hole 70. At this time, since the flange portion 13 is provided with a chamfered portion 17, the flange portion 13 is smoothly guided between the first vertical wall 40 and the third vertical wall 60. When the flange portion 13 is inserted between the first vertical wall 40 and the third vertical wall 60, the edge of the end face 18 of the flange portion 13 presses against the ribs 91, 91, causing the locking portion 90 to elastically deform, and the small diameter portion 16 of the column portion 12 is guided from the wide portion 72 to the narrow portion 73 of the first slide hole 70 and into the second slide hole 80.

[0024] As shown in Figure 7, when the small-diameter portion 16 of the column portion 12 reaches the second slide hole 80, the locking portion 90 returns to its initial shape, causing the rib 92 of the locking portion 90 to face one end face 18 of the flange portion 13, and the other end face 18 of the flange portion 13 to rest on the stopping surface 44 of the rib 43. The elastic deformation of the locking portion 90 and its return to its initial shape described above can be visually observed by the operator from the wide portion 72 of the first slide hole 70. Furthermore, since the width dimension W2 of the wide portion 72 and the width dimension W3 of the narrow portion 73 are less than the width dimension W1 of the flange portion 13, less than the diameter dimension D1 of the large-diameter portion 15, and greater than or equal to the diameter dimension D2 of the small-diameter portion 16, only the small-diameter portion 16 is guided relative to the wide portion 72 and the narrow portion 73.

[0025] As described above, when the small-diameter portion 16 of the column portion 12 reaches the second slide hole 80 and the locking portion 90 returns to its initial shape, the column portion 12 can move along the longitudinal direction of the second slide hole 80, but it can no longer move toward the opening 71 of the first slide hole 70. When the column portion 12 moves along the longitudinal direction of the second slide hole 80, the other end face 18 of the flange portion 13 is placed on the stopping surface 63 of the rib 62, so the column portion 12 is not strongly pressed against the inner surface of the second slide hole 80, and there is no risk of wear on the column portion 12 and the second slide hole 80.

[0026] <Effects of the Embodiment> As described above, according to the clamp locking structure according to the embodiment of the present invention, the protector 20 has a first slide hole 70 and a second slide hole 80 into which the column portion 12 can be inserted, and a locking portion 90 that locks the flange portion 13 when the column portion 12 is inserted up to the second slide hole 80 at the other end of the first slide hole 70. Therefore, the excess length of the wire, such as a wire harness, can be absorbed by the column portion 12 moving along the second slide hole 80, and even if a twisting external force is applied to the wire clamp 10 including the wire, the wire clamp 10 will not easily fall off the protector 20.

[0027] Furthermore, according to the clamp locking structure of the embodiment of the present invention, the protector 20 has a bottom wall 30, a first vertical wall 40, a second vertical wall 50, 50, and a third vertical wall 60, and a locking portion 90 is provided on the third vertical wall 60, so the locking portion 90 can be positioned at a desired location.

[0028] Furthermore, according to the clamp locking structure according to the embodiment of the present invention, since the first slide hole 70 has a wide portion 72 and a narrow portion 73, the operator can see the locking portion 90 from the wide portion 72.

[0029] Furthermore, according to the protector 20 according to the embodiment of the present invention, it has a first slide hole 70 and a second slide hole 80 into which the column portion 12 can be inserted, and a locking portion 90 that locks the flange portion 13 when the column portion 12 is inserted up to the second slide hole 80 at the other end of the first slide hole 70. As a result, the excess length of the wire harness or the like can be absorbed as the column portion 12 moves along the second slide hole 80, and the wire clamp 10 will not easily fall off even if a twisting external force is applied to the wire clamp 10 including the wire.

[0030] <Other forms> It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. Furthermore, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited as long as they can achieve the present invention.
