The O-ring 5 is disposed between the retainer 4 and the step surface 303 a (the inner peripheral surface of the interposition part 303) between the large-diameter cylindrical part 302 and the small-diameter cylindrical part 301. In the present embodiment, the stepped surface 303 a is tapered such that the inner diameter increases toward the large-diameter cylindrical portion 302, but the stepped surface 303 a is an annular shape orthogonal to the central axis direction of the main body 30 of the housing 3. It may be a flat surface.

  The ferrule 6 is made of a highly conductive metal such as brass, and the braided shield 23 folded back in the large-diameter cylindrical portion 302 in the main body 30 of the housing 3 is disposed between the inner peripheral surface of the large-diameter cylindrical portion 302. A cylindrical shape sandwiched between the two. In the main body 30 of the housing 3, the folded braided shield 23 is pressed against the outer peripheral surface of the ferrule 6 by caulking the large-diameter cylindrical portion 302. Thereby, the braided shield 23 is electrically connected to the housing 3 and the ferrule 6.

  The spacer 7 is a cylindrical member that is softer and less elastic than the ferrule 6 and is made of, for example, PVC (polyvinyl chloride) or rubber. The spacer 7 is interposed between the ferrule 6 and the unfolded braided shield 23 in a radially compressed state, and presses the braided shield 23 toward the outer peripheral surface of the electric wire body 20 by its restoring force. Yes.

  The ferrule 6 and the spacer 7 are disposed closer to the opening end 302 a side of the large-diameter cylindrical portion 302 in the main body portion 30 of the housing 3 than the retainer 4. The thickness of the ferrule 6 is, for example, 0.5 to 2.0 mm, and the thickness of the spacer 7 is, for example, twice the thickness of the ferrule 6. Moreover, the outer diameter of the electric wire main body 20 is 10 mm, for example, and the outer diameter of the large diameter cylindrical part 302 is 12-13 mm, for example.

  The wire harness 1 is assembled by the following procedure, for example. That is, a part of the braided shield that covers the electric wire body 20 of the shielded electric wire 2 is removed, the end of the braided shield 23 that remains without being removed is folded back, and the ferrule is placed inside the braided shield 23 that is folded back. 6 and the spacer 7 are arranged. Next, the retainer 4 and the O-ring 5 through which the electric wire main body 20 is inserted inside, the ferrule 6 and the spacer 7 are accommodated in the large-diameter cylindrical portion 302 of the housing 3, and the large-diameter cylindrical shape corresponding to the outside of the ferrule 6 The part 302 is crimped from the outside. The O-ring 32 is fitted into the circumferential groove 301 a formed on the outer peripheral surface of the small diameter cylindrical portion 301 before or after the large diameter cylindrical portion 302 is crimped. Thereby, the wire harness 1 is assembled.

  FIG. 3 is a cross-sectional view showing a state in which the housing 3 is fixed to the shield case 8 that is a member to be attached. For example, an electric motor or an inverter is accommodated in the shield case 8. In FIG. 3, a part of the shield case 8 around the portion to which the housing 3 is fixed is shown in cross section.

  The shield case 8 is formed with a through hole 8a into which the small diameter cylindrical portion 301 of the housing 3 is fitted. A space between the inner peripheral surface of the through hole 8 a and the small diameter cylindrical portion 301 of the housing 3 is sealed with an O-ring 32. The flange portion 31 of the housing 3 is fixed to the shield case 8 with bolts 81. The bolt 81 has a shaft portion 811 in which a male screw is formed and a head portion 812 provided at an end portion of the shaft portion 811, and the shaft portion 811 is inserted into the bolt insertion hole 31 a of the flange portion 31 so as to be shielded. 8 is screwed into the screw hole 8b.

  When the shielded electric wire 2 is mounted on a vehicle, the shielded electric wire 2 bends as shown in FIG. In this case, if the wire harness 1 does not have the retainer 4 and the large-diameter cylindrical portion 302 of the housing 3 is formed to be as short as the retainer 4, the phantom line (two-dot chain line) in FIG. Although the electric wire main body 20 can be greatly bent, the compression rate of the O-ring 5 is reduced outside the curve, and the sealing performance is reduced. However, in the present embodiment, the bending of the electric wire body 20 inside the O-ring 5 is regulated by the retainer 4, and the compression rate of the O-ring 5 is maintained in an appropriate range, so that the sealing performance is kept good.

  That is, when the electric wire main body 20 is bent and curved, the bending of the electric wire main body 20 is regulated by the retainer 4 on the small diameter cylindrical portion 301 side than the retainer 4, and the posture of the electric wire main body 20 is kept linear. As a result, the radial gap between the inner peripheral surface of the large-diameter cylindrical portion 302 and the outer peripheral surface of the electric wire body 20 is not greatly opened outside the curve of the electric wire body 20, and the sealing performance by the O-ring 5 is maintained. Be drunk. For this reason, it is possible to reliably prevent foreign matter from entering the shield case 8 from the open end 302 a of the large-diameter cylindrical portion 302 by the O-ring 5.

  The retainer 4 also has a function of preventing the braided shield 23 from contacting the O-ring 5. That is, the retainer 4 is interposed between the O-ring 5 and the folded portion of the braided shield 23, so that the O-ring 5 is prevented from being worn at the contact portion with the braided shield 23 due to vibration of the shielded electric wire 2 or the like. Thus, the sealing performance by the O-ring 5 is maintained.

(Comparative example)
Next, the wire harness 11 according to the comparative example will be described with reference to FIG. In FIG. 4, members that are the same as or correspond to those of the wire harness 1 according to the first embodiment are given the same reference numerals, and redundant descriptions are omitted.

  The wire harness 11 includes a shielded electric wire 2, a housing 3, a ferrule 6, and a heat shrinkable tube 9. The shielded electric wire 2 includes an electric wire body 20, a braided shield 23 that is folded back in the housing 3, and a sheath 24 that covers the braided shield 23. The housing 3 includes a main body portion 30 and a flange portion 31, and the main body portion 30 includes a small diameter cylindrical portion 301, a large diameter cylindrical portion 302, and an interposition portion 303. Further, the housing 3 according to the comparative example has an outer diameter smaller than the outer diameter of the large-diameter cylindrical portion 302 on the outer peripheral surface of the small-diameter cylindrical portion 301 on the larger-diameter cylindrical portion 302 side than the flange portion 31. A constricted portion 301b is formed.

  In the heat shrinkable tube 9, one end on the flange portion 31 side of the housing 3 is accommodated in the constricted portion 301 b, and the inner surface at the other end is in close contact with the outer peripheral surface of the sheath 24 of the shielded electric wire 2. The hot melt adhesive G is filled inside the end portion on the opening end 302 a side of the large-diameter cylindrical portion 302 of the housing 3. The hot melt adhesive G prevents foreign matter from entering the small diameter cylindrical portion 301 from the gap between the outer peripheral surface of the sheath 24 and the inner peripheral surface of the large diameter cylindrical portion 302.

  When the wire harness 11 is manufactured, the hot melt adhesive G in a solid state is disposed inside the end portion on the opening end 302a side of the large-diameter cylindrical portion 302, and the heat-shrinkable tube 9 before contraction is disposed outside the solid-state hot melt adhesive G. Then, by heating the hot melt adhesive G and the heat shrinkable tube 9, the hot melt adhesive G is melted and the heat shrinkable tube 9 is contracted. At this time, leakage of the molten hot melt adhesive G is suppressed by contraction of the heat shrinkable tube 9.

  Further, when the wire harness 11 is manufactured, the heat-shrinkable tube 9 in the vicinity of the opening end 302a of the large-diameter tubular portion 302 is contracted, so that the force in the direction in which the large-diameter tubular portion 302 is pushed out of the heat-shrinkable tube 9 is received. As the reaction force, a moving force from the small diameter cylindrical portion 301 side to the large diameter cylindrical portion 302 side acts on the heat shrinkable tube 9. However, the movement of the heat-shrinkable tube 9 in this direction is suppressed by accommodating one end of the heat-shrinkable tube 9 in the constricted portion 301b of the housing 3.

In the wire harness 11 according to this comparative example, it is necessary to form the constricted portion 301b on the outer peripheral surface on the larger diameter tubular portion 302 side than the flange portion 31 in the small diameter tubular portion 301. the length L ₁₁ to the opening end 302a of the large-diameter cylindrical portion 302 from the flange portion 31 in the axial direction, than the dimension L ₁ of the same portion of the wire harness 1 according to the first embodiment _(shown in FIG. 1) Also gets longer. In other words, in the wire harness 1 according to the first embodiment, since it is not necessary to provide the constricted portion 301b, the protruding length of the housing 3 at the portion protruding from the shield case 8 can be shortened. The mountability of is improved.

(Operation and effect of the first embodiment)
According to the first embodiment described above, the following operations and effects can be obtained.

(1) Since the bending of the electric wire main body 20 inside the O-ring 5 is restricted by the retainer 4, the O-ring 5 is provided between the inner peripheral surface of the large-diameter cylindrical portion 302 of the housing 3 and the outer peripheral surface of the electric wire main body 20. Can be surely sealed. For this reason, for example, the hot-melt adhesive G of the wire harness 11 according to the comparative example and the heat-shrinkable tube 9 that suppresses leakage of the hot-melt adhesive G are not necessary, and it is not necessary to provide the constricted portion 301b in the housing 3. Therefore, the axial length of the main body 30 of the housing 3 can be shortened, and the mounting property to the vehicle is improved.

(2) Since the wire harness 1 according to the first embodiment does not have the sheath 24 of the shielded electric wire 2 of the wire harness 11 according to the comparative example, the shield is compared with the wire harness 11 according to the comparative example. The diameter of the electric wire 2 can be reduced and the shielded electric wire 2 can be flexibly bent. Therefore, the mounting property on the vehicle is further improved.

(3) The braided shield 23 is folded back within the large-diameter cylindrical portion 302 of the housing 3, and the folded braided shield 23 is sandwiched between the inner peripheral surface of the large-diameter cylindrical portion 302 and the ferrule 6. The braided shield 23 can be reliably electrically connected to the housing 3.

(4) Since the braided shield 23 in the unfolded portion is elastically pressed toward the outer peripheral surface of the electric wire main body 20 by the spacer 7, the braided by the braided shield 23 sliding on the outer peripheral surface of the electric wire main body 20 The axial displacement of the shield 23 is suppressed.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. The wire harness 1A according to the second embodiment is configured in substantially the same manner as the wire harness 1 according to the first embodiment, but the shielded electric wire 2 of the wire harness 1A according to the second embodiment is The configuration in which a sheath 24 is provided on the outer periphery of the braided shield 23 and the end of the sheath 24 is disposed inside the ferrule 6 is different. The sheath 24 is made of, for example, soft polyurethane having excellent flexibility and durability. The thickness of the sheath 24 is larger than that of the ferrule 6, and the braided shield 23 in an unfolded portion is elastic toward the outer peripheral surface of the electric wire body 20. Is pressed against.

  Since the other configuration of the wire harness 1A according to the second embodiment is the same as that of the wire harness 1 according to the first embodiment, the wire harness 1 according to the first embodiment in FIG. About the common member etc., the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

  Also with the wire harness 1A according to the second embodiment, the same actions and effects as the actions and effects (1) to (3) described in the first embodiment can be obtained. Further, since the end portion of the sheath 24 is disposed between the unfolded braided shield 23 and the ferrule 6, the braided shield 23 slides on the outer peripheral surface of the electric wire body 20. Axial displacement is suppressed.
