  The pair of mini electric wire holding bars 21 is a pair of mini electric wire holding bars 21 removed from the connecting portion 31 in the connecting electric wire holding bar 20 described above (see FIGS. 5 and 6). Here, an example in which the long electric wire with terminal 7 held by the two pairs of mini electric wire holding bars 21 is supported will be described.

  The electric wire holding bar support portion 60 is a portion that supports the pair of mini electric wire holding bars 21 at intervals. The electric wire holding bar support portions 60 are configured to support the mini electric wire holding bars 21 one by one, and here, two pairs are provided to hold the two pairs of mini electric wire holding bars 21. The electric wire holding bar support portion 60 has a support base portion 62, a presser portion 64, and a retaining portion 66 (see FIG. 13).

  The support base part 62 is a part which supports the mini electric wire holding bar 21 in a mounting shape. More specifically, the support base 62 has a substantially rectangular placement surface, and has a side wall 63 standing upright at one side edge thereof. The support base 62 supports the mini electric wire holding bar 21 in a posture in which the plurality of electric wire holding portions 22 face one side in the width direction (here, the width direction of the mini electric wire holding bar 21 is substantially parallel to the height direction). To do. The support posture of the mini electric wire holding bar 21 by the electric wire holding bar support portion 60 will be described later together with the description of the fixing bracket 68.

It is good to set to the dimension below the dimension to 24 front-end | tip parts. In other words, a portion of the elastic pinching piece 23 of the mini electric wire holding bar 21 supported on the support base portion 62 that protrudes from the tip end portion of the pinching piece fixing portion 24 protrudes to the side of the support base portion 62. Further, the longitudinal dimension of the support base 62 may be set to a dimension larger than half of the longitudinal dimension of the mini electric wire holding bar 21. But the dimension of the support base 62 is not restricted to said dimension.

  The presser part 64 is a part that regulates the upward movement (floating or the like) of the mini electric wire holding bar 21 supported on the support base part 62. The presser portion 64 has a wall portion facing upward above a portion of the base end side of the support base portion 62. That is, the mini electric wire holding bar 21 is disposed at a position where a part (mainly the end member 28) including the end on one side in the longitudinal direction is sandwiched between the support base 62 and the presser 64.

  The retaining portion 66 is a portion for preventing the mini electric wire holding bar 21 supported by the electric wire holding bar support portion 60 from coming out (see FIG. 14). In the opposing location in the support base 62 and the pressing part 64, it forms in the convex shape which protrudes in the space enclosed by both from the support base 62 or the pressing part 64. As shown in FIG. Here, the retaining portion 66 projects from the inner surface of the presser portion 64 toward the support base portion 62.

  The retaining portion 66 is disposed in a retaining recess 29 a that opens on the side surface of the mini electric wire holding bar 21, thereby maintaining the state in which the mini electric wire holding bar 21 is supported. Here, the retaining recess 29 a of the mini electric wire holding bar 21 is formed on at least one side surface of at least one end member 28 in the bar main body 25. Here, the retaining recesses 29 a are formed on both surfaces of both end members 28.

  But the structure which suppresses the pull-out | removal from the electric wire holding bar support part 60 of the mini electric wire holding bar 21 is not restricted to said structure. For example, the retaining portion 66 may protrude from the inner surface of the support base portion 62 toward the presser portion 64. In the mini electric wire holding bar 21, the retaining recess 29 a may also be used as the locking recess 29, and the retaining portion 66 may be formed at a position where it can be disposed in the locking recess 29. Moreover, the uneven | corrugated relationship of the retaining structure in the mini electric wire holding bar 21 and the electric wire holding bar support part 60 may be reversed.

  The electric wire holding bar support 60 is fixed to the main body 52 by a fixing bracket 68. The fixing bracket 68 is a member that is formed by bending a plate-like metal material or the like and can be fixed to the pipe member of the main body 52. More specifically, the fixing bracket 68 is formed in a substantially P-shape in a side view in which a band plate-shaped metal material has a ring portion at an intermediate portion and is screwed by overlapping the end portions. Yes.

  The wire holding bar support 60 is fixed to the fixing bracket 68 by screwing or the like. Further, the fixing bracket 68 adjusts the inclination angle with respect to the height position and the depth direction by changing the fixing position of the main body portion 52, the fixing posture, and the fixing posture of the electric wire holding bar support portion 60, thereby adjusting the electric wire holding bar. The support part 60 can be supported (refer FIG. 9, FIG. 13). Hereinafter, the support aspect of the electric wire holding bar support part 60 is demonstrated.

  Here, the pair of electric wire holding bar support portions 60 is a pair of long electric terminals with terminals in which a pair of mini electric wire holding bars 21 holding the respective ends of the long electric wires 7 with terminals are set on the plural electric wire holding portions 22. The end portion of the electric wire 7 faces upward and is supported in such a posture that the end portion can be taken out sideways (see FIG. 11). Here, the fact that the end of the long electric wire 7 with terminal faces upward is not limited to the posture along the height direction of the wire support device 50 but also the posture inclined toward the height direction and facing upward. Shall be included. Further, the phrase “the end portion can be taken out sideways” includes not only the case where the end portion can be taken out along the width direction of the electric wire support device 50 but also the case where the end portion can be taken out sideways in a direction inclined with respect to the width direction. .

  Further, the pair of electric wire holding bar support portions 60 supports the pair of mini electric wire holding bars 21 with substantially the same extraction direction P for taking out the end portion of the long electric wire 7 with terminal from the electric wire holding portion 22. That is, the pair of wire holding bar support portions 60 are provided in parallel. Here, the other pair of wire holding bar support portions 60 are also provided in parallel with the pair of wire holding bar support portions 60.

  Moreover, the electric wire holding bar support part 60 is provided in the attitude | position which inclines with respect to the depth direction of the electric wire support apparatus 50 in planar view. More specifically, the electric wire holding bar support portion 60 supports the mini electric wire holding bar 21 in a posture in which the electric wire holding portion 22 is oriented in a direction inclined sideways toward the front side in the depth direction of the electric wire support device 50. (See FIG. 11). That is, this posture is a posture in which the end portion of the long electric wire 7 with a terminal held by the mini electric wire holding bar 21 can be taken out obliquely toward the front side. Here, the electric wire holding bar support portion 60 is provided in a posture in which the longitudinal direction of the support base 62 is inclined 20 degrees with respect to the depth direction of the electric wire support device 50 in plan view.

  Further, the pair of electric wire holding bar support portions 60 supports one of the pair of mini electric wire holding bars 21 located on the rear side in the take-out direction P at a higher position than the other located on the front side in the take-out direction P (FIG. 10). (See FIG. 13). That is, the pair of electric wire holding bar support portions 60 are fixed to the main body portion 52 by the fixing bracket 68 at different height positions. Thereby, when taking out the edge part of the long electric wire 7 with a terminal from the electric wire holding part 22 of the mini electric wire holding bar 21 supported by the electric wire holding bar support part 60, it is possible to secure an operation space of the operator's hand. It is possible to suppress the collision of the hand with respect to the adjacent electric wire holding bar support 60 and the like. Here, the other pair of wire holding bar support portions 60 are also supported at different height positions from the pair of wire holding bar support portions 60, and the pair of wire holding bar support portions 60 are provided in a step shape when viewed from the front. (See FIG. 10).

  But the structure which supports the electric wire holding bar support part 60 at the same height position, and supports each mini electric wire holding bar 21 in the same height position may be sufficient. Moreover, the electric wire holding bar support portion 60 is fixed in a posture along the depth direction of the electric wire support device 50 in a plan view, and the electric wire holding portion 22 of each mini electric wire holding bar 21 is oriented in the width direction of the electric wire support device 50. The structure to be made may be sufficient. Moreover, the structure which supports the electric wire holding bar support part 60 in the attitude | position which orient | assigns the electric wire holding part 22 upwards may be sufficient. Further, the electric wire holding bar support portion 60 is fixed in a posture in which the tip portion is inclined downward, and supports the mini electric wire holding bar 21 in an posture in which the mini electric wire holding bar 21 is inclined downward toward the front side in the depth direction of the electric wire support device 50. It may be a configuration.

  The intermediate support part 70 is a part that hooks and supports an intermediate part of the long electric wire 7 with terminals held by the pair of mini electric wire holding bars 21 supported by the pair of electric wire holding bar support parts 60 (FIG. 10). reference). That is, the long electric wire with terminal 7 is supported in a substantially W shape in front view by the pair of mini electric wire holding bars 21 and the intermediate support portion 70.

  The intermediate support part 70 is provided with a drop-off prevention part 74 for preventing the long-side electric wire 7 with a terminal from dropping out from the rod-like part 72 mainly at the tip of the rod-like part 72 to which the long electric wire 7 with terminal is hooked. It is a configuration. More specifically, the rod-shaped portion 72 is a portion that is formed in a cylindrical (or column) rod shape, and the long electric wire 7 with a terminal is hooked along the peripheral surface thereof. Further, the drop-off prevention part 74 is formed in a shape that protrudes to the outer peripheral side at the tip part of the rod-like part 72. More specifically, the drop-off prevention part 74 is externally fitted to the tip part of the rod-like part 72 and has a disk portion having a larger cross-sectional shape than the rod-like part 72. That is, the long electric wire 7 with a terminal hooked on the rod-like portion 72 is brought into contact with the proximal surface of the disc portion of the drop-off prevention portion 74 and is prevented from dropping.

  Further, the intermediate support portion 70 is provided at an intermediate position between the pair of electric wire holding bar support portions 60 in a plan view and at a height position higher than the pair of electric wire holding bar support portions 60. The intermediate support portion 70 is provided in a posture parallel to the pair of electric wire holding bar support portions 60. Here, the rod-like portion 72 is cantilevered at its base end portion by a height adjusting portion 76 fixed to the main body portion 52 so that the height position can be adjusted, whereby the intermediate support portion 70 is It is provided in position and posture.

  The height adjuster 76 is attached to the pipe member provided along the height direction in the main body 52 so as to be slidable and maintainable (see FIGS. 10 and 11). For example, the height adjusting portion 76 is a cylindrical slide member that is fitted to the pipe member, and a female screw member that can be tightened with respect to a male screw portion that is elastically deformable on the inner peripheral side of the slide member. A combination with can be employed. That is, by moving the slide member in the height direction with the female screw member loosened and tightening the female screw member, the male screw portion is elastically deformed to the inner peripheral side to maintain the height position of the slide member. Further, the posture of the intermediate support portion 70 can be adjusted by rotating the slide member with respect to the main body portion 52 in a state where the female screw member is loosened.

  However, the height adjusting unit 76 is not limited to the above-described configuration, and by tightening a male screw member that can be protruded inside the cylindrical slide member, the tip of the male screw member is fitted to a pipe member into which the slide member is fitted. It is also possible to adopt a configuration in which the height position is maintained by being pressed.

  Further, the intermediate support portion 70 is provided with a terminal from the rod-shaped portion 72 by omitting the drop-off preventing portion 74 and supporting the rod-shaped portion 72 so as to be inclined upward from the base end portion toward the distal end portion. You may be comprised so that omission of the length electric wire 7 may be suppressed.

  The pair of hook portions 80 are portions formed so as to be hookable with the respective U-turn portions of the long electric wire 7 with a terminal hanging between the pair of mini electric wire holding bars 21 and the intermediate support portion 70 (FIG. 10). FIG. 12). The hook 80 includes a hook base 82 and a curved portion 84.

  The hook base 82 is a portion on which the U-turn portion of the long electric wire 7 with a terminal is hooked, is formed in a rod shape (cylindrical or cylindrical rod shape here), and is provided along the depth direction in plan view (see FIG. 11). The hook base 82 is supported by the main body 52 at the base end. Here, the hooking base portion 82 is supported in a posture that gradually inclines downward toward the distal end portion (toward the front side in the depth direction of the wire support device 50) (see FIG. 12). The curved portion 84 is formed in a rod shape (here, a cylindrical or columnar rod shape) that is continuous with the distal end portion of the hooking base portion 82 and is curved in an arc shape that protrudes downward.

  Here, the hook portion 80 is configured by a pipe member assembled in a substantially U shape, and both end portions thereof are fixed to the main body portion 52 in the following posture. That is, the substantially U-shaped pipe member constituting the hook portion 80 has a posture in which the bottom side is directed to the front side in the depth direction of the electric wire support device 50, and a pair of opposed straight portions are in front of the depth direction in a side view. It fixes to the main-body part 52 with the attitude | position which inclines below toward the side. In this substantially U-shaped pipe member, a portion located below a pair of opposing straight portions is a hooking base portion 82, and a curved portion continuing from the bottom portion is a curved portion 84.

  Then, in a state where each U-turn portion of the long electric wire 7 with terminal passes below the pair of hook portions 80, the height adjustment portion 76 adjusts the height position of the intermediate support portion 70 to hook the U-turn portion. The hook 80 is hooked in the vicinity of the base end of the hook base 82 of the portion 80. Thereby, the long electric wire 7 with a terminal hooked on the hooking portion 80 is maintained in a state in which it cannot be pulled out when the end portion is held by the electric wire holding portion 22 of the mini electric wire holding bar 21. That is, since the hook base 82 is formed with the tip inclined downward, the U-turn portion of the long electric wire 7 with a terminal hooked on the base end is restricted from moving toward the tip of the hook base 82. Is done. For this reason, as long as an edge part is not taken out from the electric wire holding part 22 of the mini electric wire holding bar 21, it is suppressed that the U-turn part of the long electric wire 7 with a terminal remove | deviates from the hook part 80. FIG. In other words, it is possible to remove only the long terminal-attached electric wire 7 whose end portion has been taken out from the electric wire holding portion 22 from the hooking portion 80 and take it out. In FIG. 12, the long electric wire 7 with a terminal hooked near the base end portion of the hook base portion 82 in the hook portion 80, and a terminal whose one end portion is taken out from the electric wire holding portion 22 of the mini electric wire holding bar 21. The attached long electric wire 7 is indicated by a two-dot chain line. In addition, the U-turn portion of the terminal-attached long electric wire 7 removed from the hook portion 80 is smoothly taken out along the curved portion 84 that is continuous with the tip portion of the hook base portion 82.

  Moreover, the electric wire support device 50 may have a side guide portion 59 that suppresses the protruding of the long electric wire 7 with a terminal to the side on the side of the pair of hook portions 80. The side guide portion 59 is formed in a plate shape, and is provided so that the posture can be changed from a posture orthogonal to the width direction of the electric wire support device 50 to a posture that is opened outwardly around an axis along the height direction. Yes.

  Up to now, the electric wire support device 50 has been described by taking as an example the configuration for supporting the long electric wire 7 with terminals held by the two pairs of mini electric wire holding bars 21. The structure which supports the long electric wire 7 with a terminal hold | maintained at a pair of mini electric wire holding bar 21 is also employable. For example, the wire support device 150 that supports the long electric wires 7 with terminals held by the four pairs of mini wire holding bars 21 shown in FIG. 60, the intermediate support part 70, and a pair of hook part 80 can be provided symmetrically. That is, two sets of two pairs of electric wire holding bar support portions 60 and two intermediate support portions 70 are provided in such a posture that the tip portions are directed outward in the width direction and inclined with respect to the depth direction. However, the four pairs of wire holding bar support portions 60 and the four intermediate support portions 70 may all be supported in a posture inclined in the same direction.

  Moreover, although demonstrated in the example which supports the long electric wire 7 with a terminal in the electric wire support apparatus 50, you may support the general electric wire 5 with a terminal.

  The wire support device 50 supplies the long electric wire 7 with terminal to the temporary bundling step after the cutting pressure setting step, and also the long electric wire 7 with terminal in the intermediate processing step, the main bundling step (wire harness assembly step) and the like. Can be used for the purpose of supplying.

<Wire harness manufacturing method>
Next, the manufacturing method of the wire harness 1 is demonstrated in the example using the said connection type electric wire holding bar 20 and the electric wire support apparatus 50 (refer FIG. 1).

  First, a terminal is crimped | bonded to the edge part of the general electric wire and long electric wire which were obtained by elongating and cutting an electric wire, and the general electric wire 5 with a terminal and the long electric wire 7 with a terminal are manufactured. This operation may be performed by a cutting pressure mechanism 92 including a scale cutting machine opening and a terminal crimping mechanism.

  The general electric wire 5 with a terminal is set on the general electric wire holding bar 10. More specifically, the end portions of the plurality of types of general electric wires 5 with terminals are individually set so as to be arranged in the order in which they are taken out into the plurality of electric wire holding portions 12 of the general electric wire holding bar 10 (see step (a) and FIG. 2). . Here, the order of taking out is the work order such as the order of inserting the terminals in the general electric wire 5 with terminals into the connector housing or the like in the temporary binding step. Moreover, it is good for one general electric wire holding | maintenance bar 10 to hold | maintain the multiple types of general electric wire 5 with a terminal used in order to produce the one temporary binding 2. FIG.

  The long electric wire with terminal 7 is set on the connection type electric wire holding bar 20. More specifically, the end of the long electric wire 7 with a terminal is set to a plurality of electric wire holding portions of the connection type electric wire holding bar 20 (step (b)). Here, while setting one edge part of the long electric wire 7 with a terminal to the some electric wire holding part 22 in one mini electric wire holding bar 21 of a pair of mini electric wire holding bars 21, it is the long electric wire 7 with a terminal. Is set on the plurality of electric wire holding portions 22 in the other mini electric wire holding bar 21 (see FIG. 3). Here, the plurality of long electric wires 7 with terminals may be set so that both ends thereof are arranged in the same order in both the pair of mini electric wire holding bars 21. For example, the pair of mini electric wire holding bars 21 connected in series can be set in order from the circulation mechanism 96 side to the cutting pressure mechanism 92 side. That is, if a pair of mini electric wire holding bar 21 is hold | maintained in parallel, the hold | maintained long electric wire 7 with a terminal can be extended and supported in parallel, without mutually crossing. Moreover, it is good for one connection type electric wire holding bar 20 to hold | maintain the long electric wire 7 with a terminal of the same type or the kind with which the length dimension of an electric wire part is the same or near.

  The operation of setting the end portions of the general electric wire 5 with terminals and the end portions of the long electric wires 7 with terminals in the electric wire holding portions 12 and 22 may be performed by the transfer mechanism portion 94.

  The general electric wire holding bar 10 holding the general electric wire 5 with terminal and the connection type electric wire holding bar 20 holding the long electric wire 7 with terminal are transferred from the transfer mechanism portion 94 to the circulation mechanism portion 96, and on the same path. Support and circulate with. When the general electric wire holding bar 10 or the connection side electric wire holding bar 20 is moved from the delivery position to the extraction position, the general electric wire holding bar 10 or the connection side electric wire holding bar 20 is taken out at the extraction position.

  One or a plurality of general electric wire holding bars 10 taken out from the circulation mechanism unit 96 are supported as they are on a dedicated carriage or the like and used for the temporary binding step.

  On the other hand, the connection type electric wire holding bar 20 taken out from the circulation mechanism part 96 is handled with the pair of mini electric wire holding bars 21 removed from the connection part 31. That is, one mini electric wire holding bar 21 is removed from the connecting portion 31 and supported by one electric wire holding bar support portion 60 of the pair of electric wire holding bar support portions 60, and the other mini electric wire holding bar 21 is removed. It supports to the other electric wire holding bar support part 60 (refer FIG. 10). More specifically, one mini electric wire holding bar 21 is supported by one electric wire holding bar support portion 60, and an electric wire portion spanned between the pair of mini electric wire holding bars 21 is passed under one hook portion 80. The intermediate portion of the electric wire portion is hooked on the intermediate support portion 70, and the further portion is passed below the other hook portion 80 to support the other mini electric wire holding bar 21 on the other electric wire holding bar support portion 60. . That is, the pair of mini electric wire holding bars 21 and the intermediate support portion 70 support the plurality of long electric wires 7 with terminals in a substantially W shape when viewed from the front. And the height position of the intermediate | middle support part 70 is adjusted, and each U-turn part hanging down between a pair of mini electric wire holding bar 21 and the intermediate | middle support part 70 is made into the state caught on each hook part 80 (refer FIG. 12). ).

  Thereafter, the other connection type electric wire holding bar 20 is taken out, the mini electric wire holding bar 21 is supported on all of the plural pairs of electric wire holding bar support portions 60 in the electric wire support device 50, and the plurality of long electric wires 7 with terminals are attached. It is supported by the electric wire support device 50. Thereby, it uses for the temporary binding process in the state which supported the long electric wire 7 with a terminal by the electric wire support apparatus 50. FIG.

  In addition, the general electric wire holding bar 10 and the connection type electric wire holding bar 20 taken out from the circulation mechanism unit 96 may be used for an intermediate processing step such as twist processing in addition to the temporary binding step.

  Then, in the temporary binding step, the general electric wire 5 with terminal and the long electric wire 7 with terminal are taken out from the general electric wire holding bar 10 and the mini electric wire holding bar 20 and are bundled together to create the temporary binding 2 (step (step ( c)).

  When taking out the long electric wire 7 with a terminal from the electric wire support device 50, one end thereof is taken out from the electric wire holding part 22 of the one mini electric wire holding bar 21 while being lowered downward (making slack). The U-turn portion is removed from the hook portion 80 (see FIG. 12), and the one end portion is set in a connector housing or the like. Further, the long electric wire 7 with terminal is removed in order from the intermediate support portion 70 and the other hooking portion 80, and the other end portion is taken out from the electric wire holding portion 22 of the other mini electric wire holding bar 21 and set in the connector housing or the like. .

  In this temporary bundling step, the processed electric wire processed through the intermediate treatment step may be bundled together with the general electric wire 5 with terminal and the long electric wire 7 with terminal.

  Then, the created plurality of temporary bundles 2 are subjected to a wire harness assembling process to be bundled, and the wire harness 1 is assembled. The wire harness assembly process may be provided with a processed electric wire processed through an intermediate processing process.

  But even if the general electric wire 5 with a terminal and the long electric wire 7 with a terminal are manufactured by another cutting pressure mechanism part 92, the general electric wire holding bar 10 and the connection type electric wire holding bar 20 are circulated by another circulation mechanism part 96. Good.

  According to the method for manufacturing the wire harness according to the embodiment, the ends of the general electric wires 5 with terminals are individually set in the order in which they are taken out to the plurality of electric wire holding portions 12 of the general electric wire holding bar 10, so that the binding work can be efficiently performed. it can. Moreover, after handling the long electric wire with a terminal separately from the general electric wire 5 with the terminal and setting the end portions thereof to the plural electric wire holding portions 22 of the connection type electric wire holding bar 20, the general electric wire 5 with the terminal and the long electric wire with the terminal are set. Since the electric wires 7 are bundled together, the long electric wires 7 with terminals can be handled while suppressing tangling, and the bundling operation including the long electric wires 7 with terminals can be performed smoothly. Thereby, workability | operativity of the manufacturing process of the wire harness 1 can be improved.

  Moreover, while setting one edge part of the long electric wire 7 with a terminal to the some electric wire holding part 22 in the one mini electric wire holding bar 21, the other edge part of the long electric wire 7 with a terminal hold | maintains the other mini electric wire. Handling of the long electric wire 7 with a terminal in a subsequent process such as supporting the hanging portions of the long electric wire 7 with a terminal between the pair of mini electric wire holding bars 21 in order to set the plural electric wire holding portions 22 in the bar 21. And the workability of the manufacturing process of the wire harness 1 can be further improved.

  Further, in the electric wire support device 50, a pair of mini electric wire holding bars 21 in which the ends of the long electric wires 7 with terminals are set on the electric wire holding portions 22 are supported by the pair of electric wire holding bar support portions 60 with a space therebetween. The intermediate portion of the long electric wire with terminal 7 held by the pair of mini electric wire holding bars 21 is hooked and supported by the intermediate support portion 70. According to this arc configuration, the long electric wire 7 with a terminal can be supported in a W shape, so that space can be saved, and the hang-up of the long electric wire 7 with a terminal is suppressed and the entanglement is suppressed. The workability of the manufacturing process 1 can be improved.

  In addition, each U-turn portion that hangs down between each of the pair of mini electric wire holding bars 21 and the intermediate support portion 70 is hooked on the pair of hook portions 80, so that the entanglement between the hanging portions can be suppressed.

  Moreover, since the hook part 80 is supported by the base end part and formed in a shape that is inclined downward toward the tip part, the U-turn part of the long electric wire 7 with terminal is prevented from coming off from the hook part 80, It can be removed from the hook portion 80 only when the end portion of the long electric wire 7 with terminal is taken out from the electric wire holding portion 22 of the mini electric wire holding bar 21.

  Moreover, since the intermediate support part 70 has the height adjustment part 76 and is comprised so that adjustment of a height position is possible, the height which supports the intermediate part of the long electric wire 7 with a terminal is adjusted, and the length with a terminal is adjusted. It is possible to suppress the hanging of the electric wire 7 to the floor. Further, by adjusting the height of the intermediate support portion 70 to a position where each U-turn portion is hooked by the pair of hook portions 80, it is possible to more reliably suppress the U-turn portion from coming off the hook portion 80. Only the long electric wire 7 with a terminal to be taken out can be taken out.

  In addition, the mini electric wire holding bar 21 has a posture in which the end portion of the long electric wire 7 with a terminal set in the electric wire holding portion 22 faces upward and the end portion can be taken out in the horizontal direction. Therefore, it is easy to take out the long electric wire 7 with a terminal. In other words, since the end of the long electric wire 7 with terminal can be taken out to the side, it is possible to suppress the U-turn portion from being caught by the hooking portion and to pull the U-turn portion to the hooking portion as compared with the case where it is taken out upward. The end part of the electric wire with a terminal can be taken out from the electric wire holding part of the electric wire holding bar in the hung state.

  The electric wire holding bar support 60 supports the pair of mini electric wire holding bars 21 in the same taking-out direction and positions one of the pair of mini electric wire holding bars 21 located on the rear side in the taking-out direction on the front side. When the end of the long electric wire 7 with a terminal is taken out from one mini-wire holding bar 21 of the pair of mini-wire holding bars 21, the other mini-wire holding bar 21 is connected to the other mini-wire holding bar 21. Interference can be suppressed and the long electric wire 7 with terminal can be taken out smoothly.

  Further, according to the electric wire support device 50, the long electric wire 7 with a terminal is accommodated inside the hook-shaped member, and compared with an apparatus configured to be able to be pulled out from the hook-shaped member in temporary binding work or the like. The drawing work can be omitted. For this reason, while being able to suppress the external rubbing of the long electric wire 7 with a terminal accompanying extraction, the deformation | transformation etc. by the catch of a terminal can also be suppressed. Moreover, the electric wire support apparatus 50 can omit the winding form preparation work for conveyance of the some long electric wire 7 with a terminal, and the injection | throwing-in work to a bowl-shaped member compared with the said apparatus.

  Moreover, since the connection type electric wire holding bar 20 connects the pair of mini electric wire holding bars 21 detachably in series at intervals by the connecting portion 31, it can be handled in the same manner as the general electric wire holding bar 10 in the connected state. it can. Further, in the disconnected state, the pair of mini electric wire holding bars 21 can be handled separately. That is, in the disconnected state, the long electric wire 7 with a terminal can be handled by holding each end portion of the pair of the mini electric wire holding bars 21 and supporting a portion hanging between them. Thereby, even if it is a case where the long electric wire 7 with a terminal is comparatively long, drooping to a floor, a tangle, etc. can be suppressed and the workability | operativity of the manufacturing process of the wire harness 1 can be improved.

  Moreover, the connection part 31 has the rail part 32 which supports a pair of mini electric wire holding bar 21 in series, and the positioning part 35 which regulates each position of a pair of mini electric wire holding bar 21 in the longitudinal direction of the rail part 32. Since it has, the connection space | interval of a pair of mini electric wire holding bar 21 can be adjusted with the positioning part 35. FIG. And when connecting so that it may become the same length dimension as the general electric wire holding bar 10 as a whole, handling becomes convenient.

  Moreover, since the positioning part 35 has the latching | locking part 37 which can be latched to the recessed part 29 for latching of the mini electric wire holding bar 21, it can maintain the connection state of a pair of mini electric wire holding bar 21 reliably. Can do.
