The pair of arc portions 461a and 461b face each other. On the other hand, the first recess 463a and the second recess 463b sandwich the claw portion 12 and restrain the terminal 10 in the plane direction (XY plane direction in the drawing). The pair of recesses 463a and 463b are also opposed to each other, and the distance L _h between the bottom surfaces 463c and 463d is slightly larger than the width W _c (see FIG. 5) of the claw portion 12 (L _h > W _c ).

The first concave portion 463a is connected to the first arc portion 461a via the first convex portion 462a, and the rotation direction of the claw portion 12 (θ in FIGS. 12A and 12B described later). In the direction (the clockwise direction in FIG. 12A, the counterclockwise direction in FIG. 12B), it is located on the terminal side of the first arc portion 461a. The first arc portion 461 a is recessed in a curved shape toward the outside of the terminal holding hole 46. The first recess 463 a is also recessed toward the outside of the terminal holding hole 46. The distance W _h between the parallel surfaces 463e and 463f facing each other of the first recess 463a is slightly larger than the thickness t _c (see FIG. 5) of the claw portion 12 (W _t > t _c ).

The second slit 467 in the present embodiment corresponds to an example of a slit in the present invention.

  Note that the second slit 467 may not be provided in the terminal holding hole 46. In this case, the claw portion 12 is inserted into the terminal holding hole 46 by causing the claw portion 12 to approach the terminal holding hole 46 from the front.

As shown in FIGS. 6 to 8 and 10, the protruding piece 47 protrudes toward the main body 43 by a predetermined distance from the main body 43, and is in a direction substantially parallel to the main body 43 ( It extends in the XY plane direction in the figure. Therefore, a groove 471 is formed between the protruding piece 47 and the main body 43. The groove 471 has a width W _g (see FIG. 8) slightly larger than the thickness t _t (see FIG. 5) of the main body 11 of the terminal 10 (W _g > t _t ). When a part of the main body portion 11 of the terminal 10 enters the groove 471, the groove 471 causes the terminal 10 to be substantially orthogonal to the plane direction of the terminal 10 (XY plane direction in the drawing) ( Restrained in the Z direction in the figure.

  As shown in FIG. 10, the bottom surface 472 of the groove 471 has a shape along the side surface 112 of the main body 11 of the terminal 10. Thereby, when the main body 11 enters the groove 471, the main body 11 comes into close contact with the bottom surface 472, and the groove 471 restrains the terminal 10 also in the plane direction (XY plane direction in the drawing). The groove 471 in the present embodiment corresponds to an example of the groove in the present invention, and the bottom surface 472 of the groove 471 in the present embodiment corresponds to an example of the bottom surface of the groove in the present invention.

  Below, the manufacturing method of the wire harness 1 in this embodiment is demonstrated, referring FIGS.

  FIG. 11 is a front view showing a first stage of the manufacturing method in the present embodiment, and FIGS. 12A and 12B are a front view showing second and third stages of the manufacturing method in the present embodiment. FIG. 13 is a rear view, and FIG. 13 is an enlarged view of a portion XIII in FIG.

  First, as shown in FIG. 11, in the first stage, the claw portion 12 of the terminal 10 is inserted into the second slit 467 from the opening 467 b (see FIG. 9) of the terminal holding hole 46 of the connector holder 40. Then, the claw portion 12 is slid along the second slit 467 and moved to the first and second arc portions 461 a and 461 b of the terminal holding hole 46.

  Next, as shown in FIGS. 12A and 12B, in the second stage, the claw portion 12 is rotated along the first and second arc portions 461a and 461b. With this rotation, a part of the main body 11 of the terminal 10 starts to enter the groove 471.

When the claw portion 12 is further rotated in the terminal holding hole 46, as shown in FIG. 13, as the claw portion 12 approaches the first and second convex portions 462a and 462b, the claw portion 12 has the first arc. The first piece 44 is slid to the side of the portion 461 a and presses the first piece 44, and the first piece 44 is elastically deformed and separated from the second piece 45. In this case, in the present embodiment, since the length L _t from the tip of the main body portion 11 to the rear end is longer than the width W _t of the main body portion _{11 (L t> W t)} , the principle of leverage It is possible to easily elastically deform the first piece 44 using the above.

  When the first piece 44 is separated from the second piece 45, the rotating claw portion 12 gets over the first and second convex portions 462a and 462b, and in the third stage, the first and second , And the elastic deformation of the first piece 44 is released. As described above, when the claw portion 12 is rotated 90 degrees in the terminal holding hole 46, the claw portion 12 enters the first and second recesses 463 a and 463 b and the first bolt insertion hole 111 of the terminal 10. And the second bolt insertion hole 481 of the connector holder 40 overlap.

At this time, as shown in FIG. 9, the distance L _h between the bottom surfaces 463c and 463d of the first and second recesses 463a and 463b is slightly larger than the width W _c of the claw portion 12 (L _h > W _c ), the distance W _h between the parallel surfaces 463e and 463f of the first recess 463a is slightly larger than the thickness t _c of the claw portion 12 (W _h > t _c ), and the second recess The distance W _h between the parallel surfaces 463g and 463h of 463b is also slightly larger than the thickness t _c of the claw portion 12 (W _h > t _c ). Therefore, the claw portion 12 is engaged with the first and second recesses 463a and 463b, and the first and second recesses 463a and 463b connect the claw portion 12 to the plane direction of the terminal 10 (XY in the drawing). Constraint in the plane direction).

Further, as the claw portion 12 rotates, a part of the main body portion 11 further enters the groove 471. In the state where the claw portion 12 is locked to the first and second recesses 463 a and 463 b, the side surface 112 of the main body portion 11 is in contact with the bottom surface 472 of the groove 471. At this time, since the width W _{g of the} groove 471 is slightly larger than the thickness t _t of the main body portion 11 (W _g > t _t ), the groove 471 connects the terminal 10 to the plane direction of the terminal 10. Restraining in a substantially orthogonal direction (Z direction in the figure).

  In the present embodiment, the bottom surface 472 of the groove 471 has a shape along the side surface 112 of the main body 11. For this reason, the main-body part 11 closely_contact | adheres to the bottom face 472 of the groove | channel 471, and the groove | channel 471 restrains the terminal 10 also in a plane direction (XY plane direction in a figure).

  Although the electric wire 20 is not shown in FIGS. 11 to 13, it is preferable that the electric wire 20 is connected in advance to the terminal 10 before the terminal 10 is temporarily fixed to the connector holder 40. Further, before temporarily fixing the terminal 10 to the connector holder 40, the connector 30 to which the electric wire 35 is connected may be attached to the connector holder 40 in advance. Alternatively, after temporarily fixing the terminal 10 to the connector holder 40, the connector 30 to which the electric wire 35 is connected may be attached to the connector holder 40.

  As described above, in the present embodiment, the terminal 10 has the claw portion 12, and the connector holder 40 has the first and second recesses that restrain the claw portion 12 in the plane direction (XY plane direction in the drawing). A terminal holding hole 46 having 463a and 463b is included. In addition, the connector holder 40 includes a groove 471 that restrains the terminal 10 held in the terminal holding hole 46 in a direction substantially perpendicular to the plane direction (Z direction in the drawing). For this reason, it is possible to simplify the structure while reliably holding the terminal 10 without newly adding a part for temporarily fixing the terminal 10.

  The embodiment described above is described for facilitating the understanding of the present invention, and is not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.
