  An appropriate number of attachment portions S for attaching the holder H1 to the attachment object, two here, are provided, and a through hole 121 through which a bolt 101 (see FIG. 14) is inserted is formed. The attachment portion S will be described later.

  Next, with reference to FIGS. 6-13, the manufacturing method of the wire harness W hold | maintained at the holders H1-H7 is demonstrated. This manufacturing method includes a pre-process, an element manufacturing process, an installation process, a routing process, a covering process, a joining process, a component mounting process, and an inspection process as main processes. 6, 10, 12, and 13, the support tool 64 is omitted for convenience.

  Referring to FIG. 7, in the previous step, the coated insulator is peeled off or peeled off at both ends of the electric wire 60 cut to a predetermined length, and terminals 61 are attached to the respective ends. As a result, the element wire 1 is manufactured.

  In the element manufacturing step, each terminal 61 or a part of the terminals 61 is connected to a coupler C as a connection tool at both ends or one end of the element wire group 2 composed of a plurality of element wires 1, and is shown in FIG. As described above, various types of harness elements 62 having the length and the number of element wires 1 and the coupler C according to the device to be connected are manufactured.

  Referring to FIG. 9, in the installation process, the holder body H1a to H7a is installed on the jig plate 63 at a predetermined position via the support tool 64, and the harness element 62 to be routed is connected to the holder body H1a to H7a. As a wiring holder for holding in cooperation with each other, an electric wire holder 65 (see also FIG. 11) for holding the element electric wire 1 and a coupler holder 66 (see also FIG. 11) for holding the coupler C are respectively provided. It is installed at a predetermined position.

  The support tool 64 is provided with a plurality of pins 67 supported by the support tool 64 (see also FIG. 11), and each pin 67 passes through the plurality of through holes 15 of the holder main bodies H1a to H7a and extends upward. Extend.

  Furthermore, in this embodiment, since the lead-out portion E is provided close to the holder main body H2a, it is difficult to attach the exterior part and tape winding at the end of the branch line portion Wb near the coupler C in the covering step. For, a temporary routing is performed in which the harness element 62 routed to an appropriate number of the leading portions E among the plurality of leading portions E is routed at a position different from the original leading portion E. For the temporary wiring, a temporary coupler holder 66a as a temporary wiring jig is used as a work space in which the exterior parts can be easily attached and wound with tape, and another electric wire holder 65 and coupler holder 66 are provided. The harness element 62 is routed and arranged according to the temporary routing jig provided in a relatively small empty space 63s.

  Referring to FIG. 10, in the routing process, a plurality of harness elements 62 are mounted on the jig plate 63 on which the holder main bodies H1a to H7a, the electric wire holder 65, the coupler holder 66, and the temporary coupler holder 66a are installed. It is routed inside and outside the main bodies H1a to H7a. Specifically, the element wire group 2 is held by the holder main bodies H1a to H7a and the wire holder 65, and the coupler C is held by the coupler holder 66. The coupler C is held by the temporary coupler holder 66a for the holder main body H2a in which temporary wiring is performed. Further, when the element wire 1 is routed in the holder main bodies H1a to H7a, as shown in FIG. 11, the element wire 1 is routed using the pin 67 as a guide portion, and a branch portion Wc is also formed. The Then, in a state where the holder main bodies H1a to H7a are positioned and installed on the jig plate 63, the height of each pin 67 is higher than the side wall J2, so that the space is partitioned by the pin 67 in the upper space of the side wall J2. Since the element wire group 2 can be routed at a position beyond the side wall J2, the efficiency of the routing operation is improved.

  At this time, as shown in FIG. 11, it is guided to the pins 67a, 67a1, and 67a2, and the unbound element wire group 2 constituting the branch portion Wc is branched and guided to the pins 67b, 67b1, and 67a2. Thus, the curved portion 2a of the element wire group 2 in the unbound state is routed at a position away from the side end portion J2a or the corner portion J2b, and is guided by the pin 67c, so that the element wire group 2 in the unbound state is It is routed at a position further away from the side wall J2.

Holder covers H1b to H7b are placed over the openings D so as to be inserted into the holes 16 (see FIGS. 1, 2 and 5), and the respective engagement claws 57 are engaged with the engagement receiving portions 58. The holder covers H1b to H7b are coupled to the holder bodies H1a to H7a so as to cover the element wire group 2 arranged in the holder bodies H1a to H7a.

  In the component mounting step, the clip N and the grommet R (see FIG. 1) are mounted on the jig plate 63 at predetermined positions of the main line portion Wa and the branch line portion Wb.

  As for the holder H1, after the holder cover H2b is coupled to the holder main body H2a in the state shown in FIG. 13, the holder main body H2a is removed from the support 64, and as shown in FIG. The covering portion 3a covered with the corrugated pipe 20a is disposed in the lead-out portion E5 of the holder main body H1a, and the trunk portion Wa1 and the branch line portion Wb1 wound with tape are disposed in the lead-out portion E0, and then positioned by the pin 67. The holder cover H1b is placed on the holder body H1a so as to cover the opening D, and is coupled to the holder body H1a by the coupling means T. Then, with the holder cover H1b coupled to the holder body H1a, the pins 67 including the pins 67a, 67a1, 67a2, 67b, 67b1, 67c are removed from the holder body H3a. In the lead-out part E0, the main line part and the branch line part wound with tape are fixed and held on the holder main body H1a by tape or a band clip.

  After going through the above steps, the wire harness W held by the holders H1 to H7 is completed. The completed wire harness W is removed from the jig plate 63. At this time, the holder main bodies H1a to H7a in a state where the holder covers H1b to H7b are coupled are removed from the support 64, and at the same time, the pins 67 are removed from the holder main bodies H1a to H7a. Thereafter, in the inspection process, each coupler C is connected to a continuity tester, and a continuity inspection is performed to inspect for disconnection or terminal crimping failure. Further, the holders H1 to H7 and the coupler C are inspected for scratches and the like Inspection is performed.

The thickness of the second flange portion 105 having the abutment surface 105a that abuts the attachment surface 141 of the attachment object M in the screwing completed state is set according to the thickness of the attachment portion S at the portion where the seat surface 124a is formed. Then, the distance in the screwing direction A2 between the contact surface 104a and the mounting surface 141 in the screwing completed state is defined. In the screwing completed state, the first flange portion 104 that contacts the seat surface 124a is defined by the thickness of the second flange portion 105 having a thickness larger than the thickness of the first flange portion 104 in this embodiment. The attachment portion S is tightened in a state where the interval is maintained. Here, “thickness” is a length in the screwing direction A2.

  The attachment portion S includes a base portion 122 and a cylindrical tube portion 123 that protrudes from the base portion 122 in a direction opposite to the screwing direction A2. The through-hole 121 has one central axis L2 coinciding with the central axis of the screw hole 140, and a cross section in a plane orthogonal to the central axis L2 (hereinafter referred to as “cross section”) extends from the central axis L2. It consists of a circular hole that is a circle of different diameter at the position in the direction. The through-hole 121 formed with the inner peripheral surface of the mounting portion S as the peripheral wall surface 124 has an opening 125 sequentially provided in the screwing direction A2 parallel to the central axis L2, a first accommodating portion 126, and a second A housing portion 127.

  The opening 125 is an insertion port for the bolt 101 inserted through the through-hole 121, and is formed of a circle having a diameter d3 that is not less than the diameter d4 of the first accommodating portion 126 and larger than the diameter d5 of the second accommodating portion 127. . The first accommodating portion 126 is capable of accommodating at least a part of the first flange portion 104 in the screwing direction A2 in the screwing completion state, and in this embodiment, the first flange portion 104 so that the entire first flange portion 104 can be accommodated. The diameter d4 is larger than the outer diameter d1. The second accommodating portion 127 has a diameter d5 smaller than the outer diameter d1 of the first flange portion 104, and is external to the second flange portion 105 so that the entire second flange portion 105 can be accommodated in the screwed state. The diameter d5 is larger than the diameter d2. In this embodiment, the protruding height of the cylindrical portion 123 in which the opening 125 and the first accommodating portion 126 are formed is substantially the same as or slightly higher than the height of the head portion 102 of the bolt 101 in the screwing completed state. It is set (see FIG. 16E).

  Referring also to FIG. 15, the first accommodating portion 126 expands toward the opening 125 in at least a part of the range in the screwing direction A2, that is, the diameter of the cross section continues toward the opposite direction. It has a guide part 126a as a first guide part that becomes larger.

  In this embodiment, the first accommodating portion 126 includes a guide portion 126a that is sequentially formed in the screwing direction A2, and a restricting portion 126b that is continuous with the guide portion 126a. The minimum diameter of the guide portion 126a is set to be equal to or larger than the diameter of the restricting portion 126b, which is a portion where the first flange portion 104 is located in the screwed state, here, the diameter d4. A frustoconical guide portion 126a continuous with the opening 125 is formed by a guide surface 124b as a first guide surface, which is a portion formed of a tapered surface of the peripheral wall surface 124, and the cylindrical restricting portion 126b The wall surface 124 is formed by a peripheral wall surface portion 124c formed of a cylindrical surface. The diameter d4 of the restricting portion 126b is slightly larger than the outer diameter d1 of the first flange portion 104 in order to restrict the first flange portion 104 from moving in the radial direction. Here, the radial direction means a radial direction of the bolt 101, that is, a radial direction centered on the central axis L1 of the bolt 101.

  The second accommodating portion 127 includes a guide portion 127a as a second guide portion that is sequentially formed in the screwing direction A2, and a restricting portion 127b that is continuous with the guide portion 127a. The guide portion 127a that is continuous with the first housing portion 126 is a portion of the peripheral wall surface 124 that is formed by a curved surface having a circular cross-section in a plane including the central axis L2 (hereinafter, referred to as a “longitudinal cross section”). Is formed by a guide surface 124d as a second guide surface. The guide surface 127a is formed over a partial range in the screwing direction A2, and expands toward the first accommodating portion 126, that is, the diameter of the cross section continuously increases toward the opposite direction. Become. Further, the columnar restricting portion 127b is formed by a peripheral wall surface portion 124e formed from a cylindrical surface of the peripheral wall surface 124. The diameter of the restricting portion 127b is slightly smaller than the outer diameter d2 of the second flange portion 105 as long as the second flange portion 105 can be accommodated in order to restrict the movement of the second flange portion 105 in the radial direction. A large value is set as close as possible to the outer diameter 2d of the second flange portion 105.

  Further, the maximum diameter of the guide portion 127a is such that when the bolt 101 is screwed in a state where the first flange portion 104 is in contact with the peripheral wall surface portion 124c, the second flange portion 105 is seen from the screwing direction A2. It is located within the range of 127a, and is set to a value at which the second flange portion 105 abuts against the guide surface 124d by subsequent screwing. Further, the minimum diameter of the guide portion 127a is equal to the diameter of the restricting portion 127b.

  Further, the head 102, the shaft 103, the screw 103a, the first flange 104 and the second flange 105 in the bolt 101 are dimensioned in the screwing direction A2, and the first housing 126 and the second housing in the through-hole 121. The dimension of the portion 127 in the screwing direction A2 is appropriately set so as to satisfy the following condition.

  As shown in FIG. 16 (A), the bolt 101 is in the process of being screwed into the mounting object M, and the second flange portion 105 is in the middle state where the bolt 101 is partially screwed into the screw hole 140. 2 is not partially accommodated in the accommodating portion 127, and a gap G2 in the screwing direction A2 is formed between the second flange portion 105 and the second accommodating portion 127. A gap G1 in the screwing direction A2 is formed between the one flange portion 104 and the guide portion 126a and the opening portion 125, or the first flange portion 104 is partially accommodated in the first accommodating portion 126. It may be accommodated only in the guide part 126a. In this intermediate screwing state, the gap G2 in the screwing direction A2 formed between the second flange portion 105 and the second housing portion 127 is larger than the gap G1, and the shaft portion 103 is the second housing portion. By abutting on the peripheral wall surface portion 124e of 127 (see FIG. 16B), a restricted state in which relative movement in the radial direction is restricted between the mounting portion S and the bolt 101 is achieved. In this restricted state, the first flange portion 104 is positioned within the range of the guide portion 126a when viewed from the screwing direction A2.

Next, the screwing process will be described with reference to FIGS.
As shown in FIG. 14, the mounting portion S is applied to the mounting surface 141 of the mounting object M so that the entire screw hole 140 is located in the through hole 121 when viewed from the screwing direction A2, and then from the opening 125. The inserted bolt 101 is partially screwed into the screw hole 140 to be in a screwing intermediate state shown in FIG. In this screwed intermediate state, the first flange portion 104 is located outside the guide portion 126a and is not accommodated in the guide portion 126a or the first accommodation portion 126. Similarly, the second flange portion 105 is It is located outside the accommodating portion 127 and is not accommodated in the guide portion 127a or the second accommodating portion 127. A gap G1 between the first flange portion 104 and the opening 125 and a gap G2 between the second flange portion 105 and the guide portion 127a are formed. Further, in this screwing intermediate state, a case is shown in which both central axes L1 and L2 are coincident with each other, and the first flange portion 104 is located within the range of the guide portion 126a when viewed from the screwing direction A2. Further, the shaft portion 103 is not in contact with the peripheral wall surface portion 124e.

  In FIG. 16 (B), the attachment portion S and the attachment object M are moved relative to each other in the radial direction from the state shown in FIG. 16 (A), and the center axis L1 and the center axis L2 are displaced from each other. The bolt 101 is further screwed in. Also in this state, the bolt 101 is partially screwed into the mounting object M, and the second flange portion 105 is not housed in the second housing portion 127, and is another screwing intermediate portion from FIG. It is a state.

  In this screwed intermediate state, the attachment portion S is relatively moved so that the central axis L1 and the central axis L2 are displaced from each other, but the relative movement is caused by the shaft 103 contacting the peripheral wall surface portion 124e. Thus, the relative movement between the mounting portion S and the bolt 101 is restricted so as to prevent the center axis lines L1 and L2 from being further shifted. At this time, the first flange portion 104 is positioned within the range of the guide portion 126a as viewed from the screwing direction A2, and the first flange portion 104 is guided at a position slightly closer to the accommodating portion 127 from the opening 125. It abuts on the surface 124b. Thereafter, when the bolt 101 is further screwed in, the mounting portion S so that the central axis L1 of the bolt 101 and the central axis L2 of the through hole 121 approach each other according to the shape of the guide surface 124b in contact with the first flange portion 104. However, by moving with respect to the mounting object M, that is, the bolt 101 that is partially screwed, the mounting portion S and the mounting object M move relatively.

  Then, after the contact portion between the first flange portion 104 and the mounting portion S is shifted from the guide surface 124b to the peripheral wall surface portion 124c, a small amount or a relatively small amount of the bolt 101 is screwed in, so that FIG. ), The second flange portion 105 abuts on the guide surface 124d. Then, by subsequent screwing, according to the shape of the guide surface 124d that is in contact with the second flange portion 105, the central axis L1 and the central axis L2 approach each other so that both the central axes L1 and L2 coincide or substantially coincide with each other. When the mounting portion S moves with respect to the mounting target M, the mounting portion S and the mounting target M move relatively, and the mounting portion S has the shape of the guide surface 124d with which the second flange portion 105 is in contact. Accordingly, the central axis L1 and the central axis L2 move so as to approach each other.

  Then, when further screwed, the second flange portion 105 moves from the guide portion 127a to the restricting portion 127b. At this time, as shown in FIG. 16D, the second flange portion 105 starts to be accommodated in the restricting portion 127b of the second accommodating portion 127 in a state where both the central axes L1 and L2 are coincident or substantially coincident. Thereafter, when the bolt 101 is further screwed in, as shown in FIG. 16 (E), the second flange portion 105 abuts against the mounting surface 141 and the first flange portion 104 abuts against the seating surface 124a comprising the step surface. When the screwing is completed, the tightening force of the bolt 101 acts on the seating surface 124a, and the mounting holder H1a is fastened to the mounting object M.

Next, operations and effects of the embodiment configured as described above will be described.
The holder body H1a to H7a of each holder H1 to H7 is provided with a pin 67 that constitutes the guiding means for guiding the element wire group 2 in the unbound state of the wire harness portion Wp, and the pin 67 (for example, the pin 67a, 67a1, 67a2) branches the unbound element wire group 2 constituting the branch portion Wc, and the holder covers H1b to H7b cover the unbound element wire group 2 constituting the branch portion Wc so as to cover the holder body H1a. The element wire group 2 of the wire harness portion Wc in the holder main body H1a to H7a is covered with the covering member in a non-bundled state, that is, the element wire group 2 constituting the branch portion Wc. Since the holder covers H1b to H7b are coupled to the holder main bodies H1a to H7a and are accommodated in the mounting holders H1 to H7 in a state in which the element wire group 2 is covered with the covering member, the holder cover H1b to H7b is reduced.
