(Method for manufacturing wire harness 2)
Next, with reference to FIG.6 and FIG.7, the manufacturing method of the wire harness 2 is demonstrated. FIG. 6 is an explanatory diagram showing a process of attaching the tube 27 to the first to fifth electric wires 21 to 25 and the sheath 26. FIG. 7 is an explanatory view showing a step showing a step of winding the adhesive tape 28 around the tube 27 and its peripheral part.

  In the wire harness 2, waterproof plugs 291 to 295 are attached to the first step of removing the end of the sheath 26 and the first to fifth electric wires 21 to 25 exposed from the openings 26a of the sheath 26 formed in the first step. The second step of fitting, and the first to fifth terminals 210, 220, 230, 240, 250 on the center conductors 211, 221, 231, 241, 251 at the tip ends of the first to fifth electric wires 21-25. A third step of connecting (crimping), a fourth step of fixing the first to fifth terminals 210, 220, 230, 240, 250 and the waterproof plugs 291 to 295 to the housing 200 of the connecting connector 20, Manufactured through a fifth step of mounting the tube 27 on the outer peripheral side of the first to fifth electric wires 21 to 25 and the sheath 26, and a sixth step of winding the adhesive tape 28 around the tube 27 and its peripheral portion. It is. Hereinafter, among these steps, the fifth step and the sixth step will be described in more detail with reference to FIGS. 6 and 7.

  As shown in FIG. 6, the tube 27 is formed in a C-shaped cross section in which an axial cut is formed at one place in the circumferential direction. When the tube 27 is attached to the first to fifth electric wires 21 to 25 and the sheath 26, the notches are expanded to elastically deform the tube 27. And the 1st thru | or 5th electric wires 21-25 and the sheath 26 are inserted in the tube 27 from between the circumferential direction end surfaces 27c and 27d of the tube 27 which opposes on both sides of a notch.

  When the tube 27 is attached to the first to fifth electric wires 21 to 25 and the sheath 26, the shape of the tube 27 is restored and, as shown in FIG. 7, along the axial direction between the circumferential end surfaces 27c and 27d. Thus, a slit S is formed. That is, the tube 27 can be externally mounted on the first to fifth electric wires 21 to 25 and the sheath 26 by expanding the slit S.

  After sheathing the tube 27 on the first to fifth electric wires 21 to 25 and the sheath 26, the sheath 26 exposed from one end 271 of the tube 27 and the first to fifth electric wires exposed from the other end 272 of the tube 27 In the range including 21 to 25, the wire harness 2 is obtained by winding the adhesive tape 28 spirally so that the ends thereof overlap each other.

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

(1) Since the tube 27 is sheathed by the first to fifth electric wires 21 to 25 and the sheath 26, the first to fifth terminals 210, 220, 230, When connecting 240 and 250 (third step), and when fixing the first to fifth terminals 210, 220, 230, 240 and 250 and the waterproof plugs 291 to 295 to the housing 200 (fourth step) The operation can be performed in a state where the tube 27 is not attached to the outside of the first to fifth electric wires 21 to 25. That is, over the first through fifth wires 21 to 25 that is exposed from the opening 26a of the sheath 26 to the length of the distance D _1, since it is possible to freely bend to each other, the third step and the fourth step The work in is easy. Thereby, workability | operativity in the case of the assembly of the wire harness 2 improves.

(2) Since the first to fifth electric wires 21 to 25 exposed from the opening 26a of the sheath 26 are partially covered with the tube 27 on the opening 26a side, the first to fifth electric wires 21 to 25 are connected to the wire harness. It is possible to prevent the insulators 212, 222, 232, 242, and 252 from being worn due to vibrations and impacts associated with the traveling of the vehicle. Thereby, durability with respect to the impact and vibration of the wire harness 2 can be enhanced.

(3) Since the first to fifth electric wires 21 to 25 of the portion exposed from the other end 272 of the tube 27 are bundled by the adhesive tape 28, the first to fifth electric wires 21 to 25 are connected to each other by vibration or impact. Rubbing is suppressed. Thereby, it becomes possible to further improve the durability against impact and vibration of the wire harness 2. Further, since the vibrations of the first to fifth electric wires 21 to 25 are suppressed by bundling the first to fifth electric wires 21 to 25, the central conductors 211, 221, 231, 241, and 251 are connected to the terminal 201. It is also possible to suppress the removal from ~ 205. In addition, the outer circumferences of the first to fifth electric wires 21 to 25 exposed from the sheath 26 are covered with the tube 27 and the adhesive tape 28, and the corresponding portions are formed from the first to fifth electric wires 21 to 25 and the sheath 26. It becomes a highly rigid part whose rigidity is higher than the vehicular cable. This high rigidity portion makes it possible to suppress vibration at the end of the connection connector 20 of the wire harness 2 and further suppress the central conductors 211, 221, 231, 241, and 251 from coming out of the terminals 201 to 205. It becomes possible to do.

(4) The tube 27 has a cylindrical shape, and one end portion 271 is fixed to the sheath 26 and the other end portion 272 is fixed to the first to fifth electric wires 21 to 25 by the adhesive tape 28. It is suppressed that the 1st thru | or 5th electric wires 21-25 are bent largely in the vicinity of the opening 26a. That is, due to the rigidity of the tube 27, the first to fifth electric wires 21 to 25 are prevented from being greatly bent in the tube 27. Further, since the tube 27 has flexibility, when the first to fifth electric wires 21 to 25 are bent, the tube 27 is gently bent along the first to fifth electric wires 21 to 25, It is also suppressed that the first to fifth electric wires 21 to 25 are bent greatly in the vicinity of the other end 272. Thereby, it becomes possible to suppress disconnection or the like in a portion where the first to fifth electric wires 21 to 25 are repeatedly bent by vibration or impact.

(5) Since the tube 27 has a bellows structure, flexibility can be enhanced while maintaining the thickness of the tube 27. That is, when flexibility is improved by thinning the tube 27, tearing and deformation are likely to occur. However, by adopting a bellows structure having a large diameter portion 27a and a small diameter portion 27b, the tube 27 It is possible to increase flexibility while maintaining the strength of.

(6) Since the tube 27 is sheathed by the sheath 26 and the first to fifth electric wires 21 to 25 by expanding the slit S, the tube 27 is connected to the ends of the first to fifth electric wires 21 to 25. The tube 27 can be assembled after the connector 20 is connected. Thereby, workability | operativity in the case of the assembly of the wire harness 2 improves.

(7) Since the adhesive tape 28 is wound around the tube 27, the sheath 26 at one end 271 of the tube 27, and the first to fifth electric wires 21 to 25 at the other end 272 of the tube 27, the tube 27 Intrusion of moisture into the tube 27 from the slit S and both ends 271 and 272 is suppressed.

(8) Since the distance _{D 1} of the the connector 20 along the first to fifth wire 21-25 to the opening 26a of the sheath 26 is a 5cm above, facilitates the work in the third step and the fourth step It is possible to carry out reliably. Further, since the distance _{D 2} from the connector 20 to the other end 272 of the tube 27 is 4cm or less, the first to fifth wire 21 in between the other end 272 of the tube 27 to the connector 20 The rubbing of ~ 25 can be suppressed and durability can be improved. Furthermore, the distance _{D 2} is a 1.5cm above, inner hole for inserting the first to fifth wire 21 to 25 in the waterproof plug 291-295 is pulled by the first through fifth wires 21 through 25 Therefore, it is possible to increase the waterproof property of the housing 200.

  Moreover, although the said embodiment demonstrated the case where the tube 27 was mounted by expanding the slit S, it is not restricted to this, The tube 27 may be a cylindrical body which does not have a slit. In this case, instead of the fifth step, the tube 27 is placed before the fourth step of fixing the first to fifth terminals 210, 220, 230, 240, 250 and the waterproof plugs 291 to 295 to the connector 20 for connection.
