Figure 4 As shown, the second positioning portion 40, for example, has a convex portion 41 and a concave portion 42 for the convex portion 41 to fit in. In the present embodiment, the convex portion 41 is provided on the lower surface 31b of the protruding portion 31, and the concave portion 42 is provided on the inner surface of the lower wall 32b of the pocket portion 32. In addition, the second positioning portion 40 is not limited to this example, and for example, the convex portion 41 may be provided on the upper surface 31a of the protruding portion 31, and the concave portion 42 may be provided on the inner surface of the upper wall 32a of the pocket portion 32. In addition, the second positioning portion 40, for example, may also provide the convex portion 41 on the upper wall 32a or the lower wall 32b on the pocket portion 32 side, and provide the concave portion 42 on the upper surface 31a or the lower surface 31b on the protruding portion 31 side.

Figure 3 ) is set to be substantially the same as the opening width of the insertion space 32f in the pocket 32 ​​in the width direction Y. Furthermore, the protrusion 31 is mounted in the insertion space 32f of the pocket 32 ​​by press-fitting.

[0040] Figure 5 1 is a cross-sectional view of the first positioning portion 30 and the second positioning portion 40 of the electronic component unit 1, and is a diagram showing a state after being pressed in. Figure 5As shown, in the present embodiment, when the convex portion 41 and the concave portion 42 of the second positioning portion 40 are engaged, the first through hole 31e of the protrusion 31 and the second through hole 32e of the pocket portion 32 are arranged in a straight line in the fastening direction Z and aligned in position, and the movement of the protrusion 31 relative to the pocket portion 32 in the axial direction X and the width direction Y is restricted.

[0041] In this embodiment, when the protrusion 31 is pressed into the insertion space 32f, that is, when Figure 4 Status and Figure 5 In the state between the states, the upper wall 32a and the lower wall 32b of the resin pocket 32 ​​are elastically deformed along the fastening direction Z, thereby making it relatively easy to fit the convex portion 41 of the second positioning portion 40 into the concave portion 42 without shaking. In addition, when the convex portion 41 and the concave portion 42 are fitted, the first tapered surface 43 can be used to guide the convex portion 41 to fit into the concave portion 42 and to release the convex portion 41 from the concave portion 42.

[0042] In addition, in the present embodiment, a second tapered surface 34 is provided at the open end of the insertion space portion 32f of the pocket portion 32. The second tapered surface 34 is inclined so as to expand toward both sides of the fastening direction Z as it moves toward one side in the axial direction X (the electrical connection box 20 side). Figure 3 ) is inclined in a manner that expands toward both sides of the width direction Y as it moves toward one side of the axial direction X. That is, the second tapered surface 34 is provided at the open ends of the upper wall 32a, the lower wall 32b, and the pair of side walls 32c of the pocket portion 32. In the present embodiment, the insertability of the protrusion 31 into the insertion space portion 32f is improved by the guiding function of the second tapered surface 34.

[0043] As described above, the electronic component unit 1 and the wiring harness WH of the present embodiment include: a connection unit 10 having a connector 11 provided at the end of a wiring material W having conductivity; and an electrical connection box 20 having a counterpart connector 21 electrically and mechanically connected to the connector 11; a first positioning portion 30 having a protrusion 31 and a pocket 32, the protrusion 31 being provided on the electrical connection box 20 and protruding along the axial direction X of the wiring material W, and the protrusion 31 being provided with a first through hole 31e for fastening a bolt 33 in a fastening direction Z intersecting the axial direction X, and the pocket 32 ​​being provided on the connection unit 10 and being provided with an insertion space portion 32f and a second through hole 32e, the axial direction of the insertion space portion 32f being provided with a first through hole 31e for fastening a bolt 33 One end of the line direction X is open for the protrusion 31 to be inserted, and a pair of second through holes 32e are provided in the upper wall 32a on one side of the fastening direction Z of the insertion space portion 32f and the lower wall 32b on the other side of the fastening direction Z, and are aligned with the first through hole 31e in the fastening direction Z for the bolt 33 to be inserted; and a second positioning portion 40, which has an annular recess 42 and an annular convex portion 41, the recess 42 is provided at the peripheral portion of the second through hole 32e on the inner surface of the lower wall 32b of the pocket portion 32 and is recessed in the fastening direction Z, and the convex portion 41 is provided at the peripheral portion of the first through hole 31e in the lower surface 31b of the protrusion 31 opposite to the lower wall 32b and protrudes along the fastening direction Z and fits with the recess 42.

[0047] In addition, in the electronic component unit 1 and the wiring harness WH of the present embodiment, the upper wall 32a and the lower wall 32b of the pocket 32 ​​can be elastically deformed along the fastening direction Z, and the protrusion 31 is installed in the insertion space 32f of the pocket 32 ​​by being pressed in. According to this structure, when the protrusion 31 is pressed into the insertion space 32f of the electronic component unit 1 and the wiring harness WH, the upper wall 32a and the lower wall 32b of the pocket 32a are elastically deformed along the fastening direction Z, so that the convex portion 41 of the second positioning portion 40 can be relatively easily fitted into the concave portion 42 without shaking.

[0048] In addition, in the electronic component unit 1 and the wire harness WH of the present embodiment, a second tapered surface 34 is provided at the open end of the insertion space 32f of the pocket 32 ​​so as to be inclined in a manner that expands at least to both sides of the fastening direction Z as it moves toward one side of the axial direction X.
