  In the method for manufacturing the wire harness according to the sixth aspect, (a) a set concave portion in which the clamp portion of the first wire harness fixing clamp can be inserted from the distal end side is formed, and a restriction convex is formed in the set concave portion. The first wire harness fixing clamp setting jig provided with a portion, and a set concave portion which is erected on the drawing board main body and into which the clamp portion of the second wire harness fixing clamp can be inserted from the front end side are formed. And a second wire harness fixing clamp set jig provided with a restriction convex portion in the set concave portion, and the width of the restriction convex portion of the first wire harness fixing clamp set jig is The clamp set jig for fixing the first wire harness is larger than the width of the restricting convex portion of the clamp set jig for fixing the second wire harness. The distance between the position of the restriction surface on the opening side of the set recess and the opening of the set recess is the set recess of the second wire harness fixing clamp setting jig. Is set larger than the distance between the position of the restriction surface on the opening side and the opening of the set recess, and the bottom side of the set recess of the clamp setting jig for fixing the first wire harness and for fixing the second wire harness A step of preparing a wire harness assembling drawing board in which a detection part for detecting a set state of the clamp part to the set concave part is provided on each bottom side of the set concave part of the clamp setting jig; ) A wire fixing portion that can be attached to the wire bundle; and a pair of pillars and a pair of locking pieces that extend while inclining outward from the distal end portion to the proximal end portion of the pillar portions. A first wire harness fixing clamp comprising a clamp portion in which a groove defined by a side surface and a bottom surface facing the tip end side of the pillar portion is formed, with respect to the first wire harness fixing clamp set jig Thus, the clamping projection can be set in the set recess by fitting the regulating projection into the groove, and the clamp portion is configured for the second wire harness fixing clamp setting jig. A step of preparing the regulating convex portion in contact with the clamp portion at the bottom surface of the groove in the course of setting in the set concave portion, (c) an electric wire fixing portion attachable to the electric wire bundle, and a column portion A pair of locking pieces extending outwardly from the distal end portion of the column portion toward the proximal end portion, and defined by the pair of side surfaces and the bottom surface facing the distal end side of the column portion. Groove to be shaped A clamp for a second wire harness comprising a clamp portion formed, and for the clamp set jig for fixing the second wire harness, the restricting convex portion is fitted in the groove, and the clamp A portion can be set in the set recess, and for the first wire harness fixing clamp set jig, the restricting convex portion of the groove is set in the middle of setting the clamp portion in the set recess. (D) preparing the thing which contacts the said clamp part in both sides, (d) setting the said 1st wire harness fixing clamp to the said setting recessed part of the said 1st wire harness fixing clamp set jig, e) setting the second wire harness fixing clamp in the set recess of the second wire harness fixing clamp setting jig; (F) A plurality of electric wires are arranged on the wire harness assembling drawing board, and the plurality of electric wire fixing portions of the first wire harness fixing clamp set in the first wire harness fixing clamp setting jig Fixing the wire fixing portion of the second wire harness fixing clamp set to the second wire harness fixing clamp setting jig to the bundle portion of the plurality of electric wires, .

  According to the 1st aspect, the control convex part which can be inserted in the groove | channel of a clamp part is provided in the set recessed part. For this reason, if a groove width is smaller than the width | variety of a control convex part, a clamp part cannot be set in the setting recessed part to the back, and it cannot set. In addition, if the bottom surface of the groove is formed in a position where the clamp part is fitted into the set recess and is set in a position that contacts the restriction surface on the opening side of the set recess, the clamp part is set. It cannot be set by being fitted all the way into the recess. For this reason, even if the outer shape and size of different types of wire harness fixing clamps are similar, if the width of the groove formed on each wire harness fixing clamp and the position of the bottom surface are different, both wire harnesses The clamp for fixing can be distinguished and set on the jig. When the correct wire harness fixing clamp is set on the jig, the set state is detected by the detection unit. For this reason, even when the outer shape and size of different types of wire harness fixing clamps are similar, it is possible to easily detect whether or not the correct wire harness fixing clamp is set in the jig.

  According to the second aspect, if the correct wire harness fixing clamp is set in the jig, the clamp part is inserted into the set part to the back, and the clamp part presses the switch. Thereby, it can be easily detected whether or not the correct wire harness fixing clamp is set on the jig.

  According to the 3rd aspect, when the clamp for wire harness fixation is inclined, it can be in the state where a plurality of switches are not pushed simultaneously. Thereby, it can be detected more reliably whether or not the correct clamp for fixing the wire harness is set on the jig.

  According to the fourth aspect, when all of the plurality of switches are pushed in by the clamp portion, all of the plurality of switches are closed, and the entire switch circuit becomes energized. Thereby, it is possible to detect whether or not all of the plurality of switches have been pressed with a simple configuration.

  According to the fifth aspect, the width of the restriction convex portion of the first wire harness fixing clamp set jig is set larger than the width of the restriction convex portion of the second wire harness fixing clamp set jig. Therefore, when trying to set the clamp part suitable for the clamp set jig for fixing the second wire harness to the clamp set jig for fixing the first wire harness, the regulating convex part of the clamp set jig for fixing the first wire harness Both side portions of the groove are in contact with the clamp portion at both side portions of the groove, and the clamp portion cannot be fitted into the set recess and set. The distance between the restriction surface on the opening side of the set recess and the opening of the set recess among the restriction projections of the clamp set jig for fixing the first wire harness is the second wire harness fixing clamp. Since the distance between the position of the restriction surface on the opening side of the set concave portion and the opening of the set concave portion among the restriction convex portions of the setting jig is set, the clamp setting jig for fixing the first wire harness When trying to set a suitable clamp part on the clamp set jig for fixing the second wire harness, the control surface of the control convex part of the clamp set jig for fixing the second wire harness comes into contact with the clamp part at the bottom of the groove, The clamp part cannot be set by being fully inserted into the set recess. For this reason, even if the outer shape and size of different types of wire harness fixing clamps are similar, if the width of the groove formed on each wire harness fixing clamp and the position of the bottom surface are different, both wire harnesses The clamp for fixing can be distinguished and set on the jig. And if a correct clamp part is set to each of the clamp setting jig for 1st wire harness fixation and the clamp set jig for 2nd wire harness fixation, those set states will be detected by the detection part. For this reason, even when the outer shape and size of different types of wire harness fixing clamps are similar, it is possible to easily detect whether or not the correct wire harness fixing clamp is set in the jig.

  According to the sixth aspect, the first wire harness fixing clamp is set on the first wire harness fixing clamp set jig, and the second wire harness fixing clamp is correctly set on the second wire harness fixing clamp set jig. When set, the set state is detected by the detection unit. In this state, a plurality of electric wires can be arranged on the wire harness assembly drawing board, and the first wire harness fixing clamp and the second wire harness fixing clamp can be fixed at an accurate position of the electric wire bundle.

  Hereinafter, the clamp set jig for wire harness fixation which concerns on embodiment, the board for wire harness assembly, the manufacturing method of a wire harness, and a wire harness are demonstrated.

<Wire harness>
FIG. 1 is a schematic view showing a wire harness WH. The wire harness WH has a configuration in which a plurality of electric wires are bundled while branching along a wiring route in a vehicle or the like to be assembled. A form in which a plurality of electric wires are bundled while branching along a wiring path is referred to as a wire harness body WHa. The wire harness WH is bound by winding an adhesive tape, a binding band, or the like. At each end of the wire harness WH, the terminal at the end of the electric wire is connected to the connector C. Then, in a state where the wire harness WH is assembled to a vehicle or the like, each connector C is connected to various electrical components mounted on the vehicle or the like. Thereby, the wire harness WH plays a role as a wiring member for electrically connecting various electrical components to each other in a vehicle or the like.

  A wire harness fixing clamp is attached to the wire harness WH as a component that can be fixed to a vehicle or the like. Here, the first wire harness fixing clamp 20 and the second wire harness fixing clamp 30 are attached to the wire harness WH.

  In addition, protective components such as a clamp and a corrugated tube may be attached to the wire harness WH as necessary.

<Wire harness fixing clamp>
Different types of first wire harness fixing clamps 20 and second wire harness fixing clamps 30 are attached to the wire harness WH.

  FIG. 2 is a partial schematic front view showing the first wire harness fixing clamp 20, and FIG. 3 is a schematic bottom view showing the first wire harness fixing clamp 20.

  The first wire harness fixing clamp 20 includes an electric wire fixing portion 21 and a clamp portion 24.

  The electric wire fixing portion 21 is a portion fixed to a bundle portion of a plurality of electric wires. Here, the wire fixing portion 21 includes a band portion 22 and a band fixing portion 23.

  The band portion 22 is formed in a long band shape and is formed so as to be wound around a bundle of electric wires. A plurality of locking recesses are formed on one main surface of the band portion 22 (a surface facing inward when wound around the bundle portion) along the extending direction thereof. The locking recess is formed such that a band locking projection described later can be selectively locked.

  The band fixing part 23 is connected to one end of the band part 22 and is formed so that the band part 22 can be fixed in a state where the band part 22 is wound around the bundle part of the electric wire.

  Specifically, the band fixing part 23 is formed in a flat shape. An insertion hole 23 h is formed so as to penetrate the band fixing portion 23. The insertion hole 23h is formed in a shape that allows the band portion 22 to be inserted, and a locking projection 23a that can be selectively locked in a plurality of locking recesses of the band portion 22 is formed in the insertion hole 23h. ing.

  And the band part 22 is penetrated in the penetration hole 23h from the front-end | tip part in the state in which the band part 22 was wound around the bundle part of the electric wire. When the tip of the band portion 22 is pulled, the locking protrusion 23 a is locked to the locking recess of the band portion 22 in a state where the band portion 22 is fastened to the bundle portion of the electric wire. Thereby, the electric wire fixing | fixed part 21 is fixed to the bundle part of a some electric wire.

  The electric wire fixing portion does not need to have the above configuration. For example, the electric wire fixing portion may be formed in an elongated plate shape, and the electric wire fixing portion may be wound and fixed to the bundle portion of the electric wire with an adhesive tape or the like. Moreover, the electric wire fixing portion has a protector shape that covers a bundle portion of the electric wires, and may be fixed in a state of covering the bundle portion of the electric wires.

  The clamp portion 24 is a portion that is fixed to a fixing target portion such as a vehicle body. Here, the clamp portion 24 includes a column portion 25 and a pair of locking pieces 26.

  The clamp part 24 is formed so as to protrude outward from one main surface of the electric wire fixing part 21. The pair of locking pieces 26 are formed to extend while inclining outward from the distal end portion of the column portion 25 toward the proximal end portion. The base end side portions of the pair of locking pieces 26 are formed thinner (thin) than the other portions, and the pair of locking pieces 26 are mainly inward so as to elastically deform the base end side portions. Can be elastically deformed. A plurality of stepped portions are formed on the outward portions of the distal end portions of the pair of locking pieces 26, and the clamp portion 24 is inserted into the fixing hole of the portion to be fixed, One selectively locks to the periphery of the fixing hole.

  In addition, a disc spring portion 28 that expands toward the distal end side of the clamp portion 24 is formed at the base end portion of the clamp portion 24 (base end portion of the column portion 25).

  The clamp part 24 is fixed to the fixing target portion as follows. That is, a fixing hole is formed in the fixing target portion, and the clamp portion 24 is inserted into the fixing hole. Then, the outward surfaces of the pair of locking pieces 26 come into contact with the peripheral edge portion of the fixing hole, and the pair of locking pieces 26 are elastically deformed inward. When the most outwardly projecting portion of the pair of locking pieces 26 exceeds the peripheral edge of the fixing hole, the pair of locking pieces 26 elastically return to the original shape, and the pair of locking pieces 26 Any one of the plurality of stepped portions at the distal end is secured to the peripheral edge of the fixing hole. The disc spring portion 28 contacts the portion to be fixed from the opposite side. Thereby, the peripheral part of a fixing hole is pinched | interposed between the disc spring part 28 and the front-end | tip part of a pair of latching piece 26 among fixation object parts, and, thereby, the clamp part 24 is fixed to a fixation object part.

  A groove 27 is formed in the column part 25. Here, the groove 27 is formed on both sides of the pillar portion 25 between the pair of locking pieces 26. But the groove | channel 27 may be formed only in the surface of one side between a pair of locking pieces 26 among the pillar parts 25. FIG.

  The groove 27 is defined by a pair of side surfaces 27 a along the extending direction of the column part 25, and a bottom surface 27 b that continues to the base end side of the column part 25 with respect to the pair of side surfaces 27 a and faces the distal end side of the column part 25. Has been. The distance between the pair of side surfaces 27a and the position of the bottom surface 27b will be further described in detail in relation to the groove 37 formed in the second wire harness fixing clamp 30.

  4 is a partial schematic front view showing the second wire harness fixing clamp 30, and FIG. 5 is a schematic bottom view showing the second wire harness fixing clamp 30.

  The second wire harness fixing clamp 30 includes an electric wire fixing portion 31 and a clamp portion 34.

  The electric wire fixing part 31 is a part fixed to a bundle of electric wires in the same manner as the electric wire fixing part 21.

  Similar to the clamp portion 24, the clamp portion 34 includes a column portion 35 corresponding to the column portion 25 and a pair of locking pieces 36 corresponding to the pair of locking pieces 26. Further, the clamp portion 34 includes a disc spring portion 38 corresponding to the disc spring portion 28, similarly to the clamp portion 24. And it is fixed to a fixing object part by the structure similar to the clamp part 24 being fixed to a fixing object part.

  The outer shapes of the clamp part 24 and the clamp part 34 are the same or similar. Here, the fact that the outer shapes of the clamp part 24 and the clamp part 34 are similar is that even if a recess for setting (see a set recess described later) having a shape corresponding to each of the clamp parts 24 and 34 is formed. The clamp portions 24 and 34 are similar to the extent that they can be fitted into recesses formed on the opposite sides. In particular, the distance between the pair of locking pieces 26 of the clamp part 24 and the distance between the pair of locking pieces 36 of the clamp part 34 are the same or approximate, and are the thicknesses of the column parts 25 and 35 also the same? The external shape and size of the disc spring portions 28 and 38 are the same or approximate.

  However, the first wire harness fixing clamp 20 and the second wire harness fixing clamp 30 are not exactly the same in terms of shape and function, except for the configuration relating to the following grooves 27 and 37. For example, in the first wire harness fixing clamp 20, the band fixing portion 23 protrudes on one side of the disc spring portion 28, and accordingly, the bundle portion of the electric wires is supported at a position shifted laterally from the clamp portion 24. On the other hand, in the second wire harness fixing clamp 30, the band fixing portion 33 does not protrude from the disc spring portion 38, and accordingly, the bundle portion of the electric wires is supported immediately above the clamp portion 34. For this reason, it is necessary to avoid improperly fixing the first wire harness fixing clamp 20 and the second wire harness fixing clamp 30 to the wire harness body WHa.

  Therefore, the shapes of the grooves 27 and 37 are changed between the first wire harness fixing clamp 20 and the second wire harness fixing clamp 30.

  That is, the width W1 between the pair of side surfaces 27a of the groove 27 formed in the clamp portion 24 of the first wire harness fixing clamp 20 is equal to the width of the groove 37 formed in the clamp portion 34 of the second wire harness fixing clamp 30. It is larger than the width W2 between the pair of side surfaces 37a. Moreover, the space | interval D1 of the bottom face 27b which faces the front end side of the clamp part 24 among the groove | channels 27 formed in the clamp part 24 of the clamp 20 for 1st wire harness fixation and the base end part of the clamp part 24 is 2nd wire harness. Of the grooves 37 formed in the clamp portion 34 of the fixing clamp 30, the distance D <b> 2 is greater than the distance D <b> 2 between the bottom surface 37 b facing the distal end side of the clamp portion 34 and the proximal end portion of the clamp portion 34. It can be understood that the length of the groove 27 is shorter than the length of the groove 37.

  By changing the widths and lengths of the grooves 27 and 37 (positions of the bottom surfaces 27b and 37b) in this way, the first wire harness fixing clamp 20 and the second wire harness fixing clamp 30 are connected to the wire harness body WHa. On the other hand, it is possible to avoid fixing at a wrong position.

<Wire Harness Manufacturing Method and Wire Harness Assembly Drawing>
A configuration and method for avoiding fixing the first wire harness fixing clamp 20 and the second wire harness fixing clamp 30 at the wrong positions will be described.

  FIG. 6 is a schematic plan view showing a wire harness assembly drawing board 40 used for manufacturing the wire harness WH.

  The wire harness assembling drawing board 40 includes a drawing board main body 42, a wire harness holder 44, a first wire harness fixing clamp set jig 50 (hereinafter sometimes simply referred to as a first set jig 50), And a second wire harness fixing clamp setting jig 60 (hereinafter simply referred to as a second setting jig 60).

  The figure board main body 42 is formed in a rectangular plate shape, and is supported at a predetermined height position by a frame or the like. In the drawing board main body 42, route information corresponding to the wiring route of the wire harness WH is drawn.

  The wire harness holder 44 is a jig that holds an end portion, a branch portion, and the like of the wire harness WH. For example, the wire harness holder 44 is a jig in which a U-shaped portion is formed at the upper end portion. Then, the bundle of electric wires is held so as to be hung on the wire harness holder 44.

  FIG. 7 is a schematic plan view showing the first setting jig 50, and FIG. 8 is a schematic front view showing the first setting jig 50. The first set jig 50 is a jig that is erected on the figure body 42 and supports the first wire harness fixing clamp 20.

  More specifically, the first setting jig 50 is configured such that a rectangular parallelepiped block-shaped jig main body 52 is supported on the drawing board main body 42 by a bar-like member or the like.

  The jig main body 52 is formed with a bottomed set recess 53 that opens upward. The upper portion of the set recess 53 is formed in a concave disc spring accommodating recess 53 a that can accommodate the disc spring portion 28, and the lower (back side) portion of the set recess 53 can accommodate the clamp portion 24. It is formed in a concave clamp portion receiving recess 53b.

  The disc spring accommodating recess 53a is formed to be the same size or larger (slightly larger) than the shape and size of the disc spring portion 28 when viewed in plan, and the clamp portion accommodating recess 53b is a shape when the clamp portion 24 is viewed in plan And larger than or equal to the size. And although the clamp part 24 and the disc spring part 28 of the clamp 20 for 1st wire harness fixation can be completely accommodated in the set recessed part 53, a larger clamp part and a disc spring part cannot be completely accommodated in the said set recessed part 53. It is like that.

  Further, in the set recess 53, a restricting convex portion 54 that can be fitted into the groove 27 of the first wire harness fixing clamp 20 is provided. The width W11 of the restricting convex portion 54 is the same as or smaller than the width W1 of the groove 27 of the first wire harness fixing clamp 20, but the width W2 of the groove 37 of the second wire harness fixing clamp 30 and the restriction described later. The width of the convex portion 64 is set to be larger than the width W12. A distance D11 between the restriction surface 54f on the opening side of the set concave portion 53 in the restriction convex portion 54 and the opening of the set concave portion 53 is set with the restriction surface 64f on the opening side of the set concave portion 63 in the restriction convex portion 64 described later. It is set to be larger than the distance D12 with respect to the opening of the recess 63. The restriction convex portion 54 may be integrally formed on the inner peripheral surface of the set concave portion 63 in the jig main body 52, or may be additionally fixed by a screw, a fitting structure, or the like.

  Then, as shown in FIG. 9, when the clamp portion 24 of the first wire harness fixing clamp 20 is fitted into the set concave portion 53, the restricting convex portion 54 is fitted into the groove 27, and the column of the clamp portion 24. The portion 25 and the pair of locking pieces 26 fit into the clamp portion receiving recess 53b, and the disc spring portion 28 fits into the disc spring receiving recess 53a, so that the entire clamp portion 24 and disc spring portion 28 are provided. Is fitted into the set recess 53. In this state, the entire peripheral edge of the disc spring portion 28 comes into contact with the peripheral edge of the bottom of the disc spring accommodating recess 53a, and the clamp portion 24 is stably set in the set recess 53.

  On the other hand, as shown in FIG. 10, when the clamp portion 34 of the second wire harness fixing clamp 30 is fitted into the set concave portion 53, the restricting convex portion 54 comes into contact with the column portion 35 at both sides of the groove 37. For this reason, in the middle of fitting the clamp part 24 into the set recess 53, the clamp part 24 cannot be fitted all the way.

  In other words, the first wire harness fixing clamp 20 can be fitted and set to the first setting jig 50, but the second wire harness fixing clamp 30 cannot be fitted to the back. For this reason, the operator recognizes that the second wire harness fixing clamp 30 is not set correctly and that the second wire harness fixing clamp 30 is about to be set in an improper manner. Can do.

  A detection unit 70 that detects the set state of the clamp unit 24 in the set recess 53 is provided on the bottom side of the set recess 53. The detection unit 70 is a switch that switches an open / close state in response to a pressing operation on the pressing surface facing upward, and more specifically, a switch that switches from an open state to a closed state in response to the pressing operation. .

  A plurality (two in this case) of the detection unit 70 is provided on the bottom side of the set recess 53. The plurality of detection units 70 are dispersed in the long direction (here, the direction in which the pair of locking pieces 36 are arranged) as viewed from the direction orthogonal to the axial direction of the distal end portion (lower portion) of the clamp unit 24. It is preferable to be provided. When the clamp part 24 is set to be inclined, the difference in the vertical position of the tip part of the clamp part 24 increases in the long direction, so that it becomes difficult to push the plurality of detection parts 70 at the same time. For this reason, it can detect more reliably that the clamp part 24 is not set with the normal attitude | position.

  The plurality of detection units 70 are connected in series. Here, one end of one detection unit 70 is connected to the notification unit 72, the other end is connected to one end of the other detection unit, and the other end of the other detection unit is connected to the notification unit 72. For this reason, in the initial state, all the detection units 70 are in an open state, and a switch circuit including a plurality of detection units 70 connected in series is in an open state. Even if some of the plurality of detection units 70 are closed, the entire switch circuit is kept open. And when all the detection parts 70 are pushed in and will be in a closed state, it will be in the closed state as the whole switch circuit. When this switch circuit is in a closed state, that fact, that is, that the normal first wire harness fixing clamp 20 is set in the set recess 53 is notified through the notification unit 72. As the notification unit 72, a lamp, a sounding body (buzzer) or the like connected to the switch circuit together with a power source can be used. As the notification unit 72, a control unit connected to the switch circuit, a display device (liquid crystal display device or the like), a speaker, or the like can be used.

  Thereby, the operator can recognize that the correct first wire harness fixing clamp 20 has been set if there is a notification by the notification unit 72.

  FIG. 11 is a schematic plan view showing the second setting jig 60, and FIG. 12 is a schematic front view showing the second setting jig 60. The second set jig 60 is a jig that is erected on the drawing board main body 42 and supports the second wire harness fixing clamp 30.

  More specifically, the second setting jig 60 is configured such that a rectangular parallelepiped block-shaped jig main body 62 is supported on the drawing board main body 42 by a bar-like member or the like.

  The jig main body 62 is formed with a bottomed set recess 63 that opens upward. The upper portion of the set recess 63 is formed in a concave disc spring accommodating recess 63 a that can accommodate the disc spring portion 38, and the lower (back side) portion of the set recess 63 can accommodate the clamp portion 34. It is formed in a concave clamp portion receiving recess 63b.

  Between the first wire harness fixing clamp 20 and the second wire harness fixing clamp 30, the clamp portions 24 and 34 and the disc spring portions 28 and 38 have the same or approximate shape and size. The receiving recess 63a and the clamp portion receiving recess 63b have the same configuration as the disc spring receiving recess 53a and the clamp portion receiving recess 53b.

  Further, in the set recess 63, a regulation protrusion 64 that can be fitted into the groove 37 of the second wire harness fixing clamp 30 is formed. The width W12 of the restricting convex portion 64 is equal to or smaller than the width W2 of the groove 37 of the second wire harness fixing clamp 30, but the width W1 of the groove 27 of the first wire harness fixing clamp 20 and the restricting convex portion. It is smaller than the width W11 of 54. Further, the distance D12 between the restriction surface 64f on the opening side of the set concave portion 63 and the opening of the set concave portion 63 in the restriction convex portion 64 is equal to the restriction surface 54f on the opening side of the set concave portion 53 in the restriction convex portion 54 and the set concave portion 53. Is set to be smaller than the distance D11 to the opening.

  Then, as shown in FIG. 13, when the clamp portion 34 of the second wire harness fixing clamp 30 is fitted into the set concave portion 63, the regulating convex portion 64 is fitted into the groove 37, and the column of the clamp portion 34. The portion 35 and the pair of locking pieces 36 are fitted in the clamp portion receiving recess 63b, and the disc spring portion 38 is fitted in the disc spring receiving recess 63a, so that the entire clamp portion 34 and disc spring portion 38 are provided. Is fitted into the set recess 63. In this state, the entire periphery of the disc spring portion 38 contacts the periphery of the bottom of the disc spring accommodating recess 63a, and the clamp portion 34 is stably set in the set recess 63.

  On the other hand, as shown in FIG. 14, when the clamp portion 24 of the first wire harness fixing clamp 20 is fitted into the set recess 63, the restricting projection 64 comes into contact with the bottom surface 27 b of the groove 27. For this reason, in the middle of fitting the clamp part 34 into the set recess 63, the clamp part 34 cannot be fitted all the way.

  In other words, the second wire harness fixing clamp 30 can be fitted and set to the second setting jig 60, but the first wire harness fixing clamp 20 cannot be fitted to the back. For this reason, the operator recognizes that the first wire harness fixing clamp 20 is about to be set incorrectly when the first wire harness fixing clamp 20 cannot be fully inserted into the set recess 63. Can do.

  Further, a detection unit 70 is provided on the bottom side of the set recess 63 in the same manner as described above, and the notification by the notification unit 72 is made according to the detection result by the detection unit 70.

  As specific sizes, for example, the width W1 of the groove 27 is 6 mm, the depth (the length along the insertion direction of the clamp portion) is 4 mm, the width of the restricting convex portion 54 is 5.7 mm, and the depth (clamp) The length along the insertion direction of the portion) is less than 4 mm, the width W2 of the groove 37 is 1.7 to 2.0 mm, and the depth (the length along the insertion direction of the clamp portion) is 8 mm. It is conceivable that the width of the restricting convex portion 64 is 1.5 mm and the depth (the length along the insertion direction of the clamp portion) is less than 8 mm.

  For this reason, similarly to the above, the operator can recognize that the correct second wire harness fixing clamp 30 has been set if there is a notification by the notification unit 72. The grooves 27 and 37 are preferably 1.5 mm or more in consideration of the durability of the restricting convex portions 54 and 64 fitted into the grooves 27 and 37.

  The manufacturing method of the wire harness main body using the said wire harness assembly drawing board 40 is demonstrated.

  First, as shown in FIG. 15, a wire harness assembly drawing board 40 is prepared in which a wire harness holder 44, a first setting jig 50, and a second setting jig 60 are erected on the drawing board main body 42 (steps). (A)).

  Then, as shown in FIG. 16, the first wire harness fixing clamp 20 and the second wire harness fixing clamp 30 are prepared (step (b) and step (c)).

  Subsequently, the clamp portion 24 of the first wire harness fixing clamp 20 is fitted into the set recess 53 of the first set jig 50, and the clamp portion 24 is set in the first set jig 50 (step (d) )). At this time, if the first wire harness fixing clamp 20 and the second wire harness fixing clamp 30 are mistakenly inserted and the second wire harness fixing clamp 30 is to be fitted into the first set jig 50, the clamp portion 34. Cannot be fitted into the set recess 53 as far as it will go. Further, the notification operation of the notification unit 72 is not performed. For this reason, the operator can notice that he was trying to set the wrong second wire harness fixing clamp 30 in the first setting jig 50. Further, when the correct first wire harness fixing clamp 20 is to be fitted into the first setting jig 50, the clamp portion 24 can be fitted into the set concave portion 53, and the notification operation of the notification portion 72 is performed. . Therefore, the correct first wire harness fixing clamp 20 can be set on the first setting jig 50.

  Also, before and after this, the clamp portion 34 of the second wire harness fixing clamp 30 is fitted into the set recess 63 of the second set jig 60 and the clamp portion 34 is set in the second set jig 60 ( Step (e)). At this time, if the first wire harness fixing clamp 20 and the second wire harness fixing clamp 30 are mistakenly inserted and the first wire harness fixing clamp 20 is to be fitted into the second set jig 60, the clamp portion 24. Cannot be fitted into the set recess 63 as far as it will go. Further, the notification operation of the notification unit 72 is not performed. For this reason, the operator can notice that he was trying to set the wrong first wire harness fixing clamp 20 in the second setting jig 60. Further, when the correct second wire harness fixing clamp 30 is to be fitted into the second set jig 60, the clamp portion 34 can be fitted into the set recess 63 as far as it can be, and the notifying operation of the notifying portion 72 is performed. . For this reason, the correct second wire harness fixing clamp 30 can be set in the second setting jig 60.

  Thereafter, as shown in FIG. 17, the plurality of electric wires W are arranged on the wire harness assembly drawing board 40. Specifically, a plurality of electric wires are appropriately branched and hung on the wire harness holder 44, or on the first wire harness fixing clamp 20 and the second set jig 60 on the first set jig 50. It arrange | positions on the clamp 30 for 2nd wire harness fixing. Then, the band portion 22 of the first wire harness fixing clamp 20 is wound around the bundle portion of the electric wires W and passed through the band fixing portion 23 to be fastened and fixed. Further, the band portion 32 of the second wire harness fixing clamp 30 is wound around the bundle portion of the electric wire W and is passed through the band fixing portion 33 to be fastened and fixed. Thereby, the clamp 20 for 1st wire harness fixation, and the clamp 30 for 2nd wire harness fixation can be fixed to a correct position with respect to the wire harness main body WHa.

  Before and after this, bundling a plurality of wires with an adhesive tape, a bundling band, etc., and fixing a protector, a corrugated tube, etc. are performed as necessary.

  Thereby, the wire harness WH can be manufactured.

<Effect>
As described above, according to the present embodiment, the restriction convex portions 54 and 64 that can be fitted into the grooves 27 and 37 of the clamp portions 24 and 34 are provided in the set concave portions 53 and 63. For this reason, for example, if W2 of the groove 37 is smaller than the width W11 of the restricting convex portion 54, the clamp portion 34 cannot be fitted into the set concave portion 63 and set. In addition, if the bottom surface 27b of the groove 27 is formed at a position in contact with the restriction surface 64f on the opening side of the set concave portion 63 in the restrictive convex portion 64 while the clamp portion 24 is fitted and set in the set concave portion 63. The clamp portion 24 cannot be set by being fitted into the set recess 63 as far as it will go. For this reason, even when the outer shapes and sizes of the different types of the first wire harness fixing clamp 20 and the second wire harness fixing clamp 30 are similar, the widths of the grooves 27 and 37 and the positions of the bottom surfaces are different. If they are different, they can be distinguished and set on the setting jigs 50 and 60.

  Moreover, since the detection part 70 is provided in the back | inner side of the set recessed parts 53 and 63, when the correct clamp parts 24 and 34 can be normally set to the set recessed parts 53 and 63, this can be detected.

  Thereby, the wire harness WH in which the correct first wire harness fixing clamp 20 and the second wire harness fixing clamp 30 are attached to each position can be manufactured.

  In addition, when a switch for switching the open / close state in response to a pushing operation is used as the detection unit 70, if the correct wire harness fixing clamps 20, 30 are set in the jigs 50, 60, the clamp units 24, 34 are Since the set recesses 53 and 63 are inserted all the way into the set recesses 53 and 63, the clamp units 24 and 34 press the detection unit 70. Thereby, it is possible to easily detect whether or not the correct wire harness fixing clamps 20 and 30 are set on the jigs 50 and 60.

  Moreover, since the several detection part 70 is provided, when the clamps 20 and 30 for wire harness fixation are inclined, it will be easy to be in the state which does not press the some alerting | reporting part 72 simultaneously. Thereby, it can be detected more reliably whether the correct clamps 20 and 30 for fixing the wire harness are set on the jigs 50 and 60.

  Further, since the plurality of detection units 70 are connected in series, when all of the plurality of detection units 70 are pushed by the clamp units 24 and 34, all of the plurality of detection units 70 are in a closed state, and the switch The entire circuit is ready for energization. Thereby, it is possible to detect whether all of the plurality of detection units 70 have been pressed with a simple configuration.
