Description

  The present invention relates to a technique for manufacturing a wire harness by arranging an electric wire on an assembly drawing board.

  One method of manufacturing a wire harness is a method of bundling wired wires while wiring the wires on an assembly drawing board. In this case, a wiring jig such as a U-shaped jig or a jig for holding a connector is used for wiring the electric wire on the assembly drawing board.

  Here, Patent Document 1 discloses a jig that is erected on an assembly drawing board and holds an electric wire from which a terminal is cut off on the assembly drawing board.

Japanese Patent Laid-Open No. 11-16243

  The free wire end held by the jig or the like described in Patent Document 1 is press-connected to the connector in a later process. Thus, connecting the end of the electric wire to the connector later in the wiring process or the like is also referred to as post-insertion. However, as shown in FIG. 10, the jig 90a that holds the end portion of the free electric wire 80a is connected to the end portion of the electric wire 80a because of the space for standing the jig on the assembly drawing plate 100. The jig 90b holding the connector 82 to be inserted later may be arranged at a position crossing another electric wire 80b. In this case, when the electric wire 80a and the electric wire 80b are arranged in a crossing manner, when the electric wire 80a is removed from the jig 90a and connected to the connector 82 held by the jig 90b, the electric wires 80a and 80b are connected to each other. There is a risk of tangling. When the electric wires 80a and 80b are entangled, it may be necessary to release the entanglement, leading to a decrease in productivity.

  Then, an object of this invention is to provide the technique which can suppress that the electric wire inserted into a connector crosses with another electric wire at the time of wiring of an electric wire.

  In order to solve the above-mentioned problem, a wiring jig according to a first aspect is provided with a figure board attaching portion that can be attached to an assembly drawing board, and a support that can support an electric wire or a connector. And a holding part that is provided in the main body part and can hold the end of the electric wire.

  The manufacturing method of the wire harness which concerns on a 6th aspect is the assembly drawing by which the jig | tool for wiring provided with (a) the support part which can support an electric wire or a connector, and the holding part which can hold | maintain an electric wire edge part was arranged. A step of preparing a plate, (b) a step of holding the wire end portion in the holding portion, and wiring a connection target connector of the wire end portion, and (c) the electric wire held in the holding portion. Connecting an end to the connector to be connected.

  According to the first to fourth aspects, when the holding portion for holding the wire end portion is provided in the main body portion including the drawing plate attaching portion and the supporting portion, there is little space for standing on the assembly drawing plate. However, it is possible to arrange the holding portion at a position that does not cross another electric wire with respect to the support portion that supports the connector of the connection partner. Thereby, it can suppress that the electric wire which the said holding part holds crosses another electric wire.

  In particular, according to the second aspect, since the support portion is formed so as to be able to support the connector, for example, by using the holding portion to hold the electric wire to be inserted into the connector supported by the support portion, the electric wire Is difficult to cross with another wire. Moreover, the connector which should connect the electric wire which an operator inserts later can be recognized easily, and it becomes difficult to mistake the connecting point of an electric wire.

  In particular, according to the third aspect, an existing U jig or connector support jig or the like can be used as the main body. As a result, it is only necessary to start a new construction of the holding unit, and an increase in the number of component types and an increase in cost can be suppressed.

  Usually, the figure board mounting part of the existing U jig and the figure board mounting part of the connector support jig often include a rod-shaped part. For this reason, in particular, according to the fourth aspect, the holding part can be attached to both the U jig and the connector supporting jig with the structure of the common jig attaching part. An increase or the like can be suppressed.

  According to the fifth aspect, when the end holding portion for holding the end portion of the electric wire is provided in the support jig provided with the drawing plate attaching portion and the supporting portion, there is little space for standing on the assembly drawing plate. However, it is possible to arrange the holding portion at a position that does not cross another electric wire with respect to the support portion that supports the connector of the connection partner. Thereby, it can suppress that the electric wire which the said holding part holds crosses another electric wire. Further, an existing U jig, a connector support jig, or the like can be used as the support jig. Thereby, it is only necessary to newly start the wire end holding jig, and it is possible to suppress an increase in the number of component types and an increase in cost.

  According to the 6th aspect, the electric wire edge part which a holding part hold | maintains is connected to a connection object connector by positioning a holding part in the jig | tool side which supports a connection object connector rather than the jig | tool which supports another electric wire. At this time, the electric wire can be prevented from crossing with another electric wire.

{Embodiment}
Hereinafter, the wiring jig according to the embodiment will be described. FIG. 1 is a schematic perspective view showing a wiring jig 30 according to an embodiment and an assembly drawing board 10 including the same.

  The wiring jig 30 is attached to the assembly drawing board 10 for manufacturing a wire harness.

  Here, the assembly drawing board 10 for manufacturing the wire harness and wire harness used as manufacture object first is demonstrated.

<Wire harness>
The wire harness has a configuration in which a plurality of electric wires W are bundled while being branched as necessary in a form corresponding to a wiring route in a vehicle or the like. A terminal T is attached to the end of each electric wire W constituting the wire harness, and this terminal T is inserted and connected to the cavity Ca of the connector C (see FIG. 4). And in the state where this wire harness was incorporated in the vehicle, various electrical devices are electrically connected through this wire harness by connecting connector C to various electrical devices. Moreover, in the middle part of the wire harness, if necessary, a binding member (adhesive tape, binding band, etc.) for maintaining a plurality of wires W in a bundled state, an exterior member for protecting the wires W (corrugated tube, etc.) ) Is installed.

  In manufacturing the wire harness, an operation of arranging the electric wire W in a form corresponding to the wiring path, an operation of connecting the end of the electric wire W to the connector C, an operation of binding a plurality of electric wires W, and the like are required. . In the assembly drawing board 10, at least a part of the operations including the operation of arranging the electric wires W in a form corresponding to the wiring path is performed among these operations. Therefore, in the assembly drawing board 10, in order to arrange the electric wire W in a form corresponding to the wiring route, the jig 20 that supports the electric wire W or the connector C or the like is appropriately arranged at a position along the wiring route ( (See FIG. 1). However, if the above work is performed simultaneously on the assembly drawing board 10, the work burden on the operator is large.

  Therefore, a method of dividing the wire harness into a plurality of sub-harnesses may be employed. In this construction method, the ends of the plurality of electric wires W are connected to the connector C in advance for each sub-harness. Then, a plurality of sub-harnesses are combined on the assembly drawing board 10 and assembled into a single wire harness.

  By the way, when dividing a wire harness into a plurality of sub-harnesses, an unconnected electric wire W may be generated at least at one end of the connector C (hereinafter also referred to as a connection target connector C). The unconnected end portion of the electric wire W is connected to the connection target connector C in a state where a plurality of sub-harnesses are wired on the assembly drawing board 10, for example. In this case, the end portion of the unconnected electric wire W does not interfere with the wiring work of other sub-harnesses until it is connected to the connection target connector C after being wired on the assembly drawing board 10. It is preferable to be held in At this time, it is preferable that the unconnected electric wire W is held so as not to get entangled with other electric wires W during the wiring work or during connection after the wiring work. The wiring jig 30 according to the present embodiment is for suitably holding an unconnected electric wire W end on the assembly drawing board 10.

  The wiring jig 30 itself is not limited to the sub-harness. When a part of the electric wire W constituting the wiring harness is in an unconnected state at the time of wiring, the end of the unconnected electric wire W is used. It can be used to wire the electric wire W while holding it.

<Assembly drawing board 10>
The assembly drawing board 10 includes a plate portion 12. The plate part 12 is formed in a square plate shape, for example. The plate portion 12 may be supported in a horizontal posture (a posture in which the main surface of the plate portion 12 extends in the horizontal direction) or in a vertical posture (a posture in which the main surface of the plate portion 12 extends in the vertical direction). May be. Moreover, the board part 12 may be supported by the diagonal attitude | position in the middle of a horizontal attitude | position and a vertical attitude | position. The board portion 12 is provided with a wiring diagram, for example, and the wiring harness can be correctly wired by wiring the electric wires W along the wiring diagram. A plurality of jigs 20 are erected on the plate portion 12.

  The plurality of jigs 20 are fixed on the plate portion 12 at positions corresponding to the wiring form of the wire harness. For example, the plurality of jigs 20 are erected on the portion where the branch line portion branches from the trunk portion of the wire harness, or on the end portion of the branch line portion. And if the some electric wire W is supported by the some jig | tool 20, the said some electric wire W will be maintained in the state according to the wiring form of the wire harness. The state in which the plurality of electric wires W are maintained in a state corresponding to the wiring form of the wire harness is usually along a route in which the plurality of electric wires W two-dimensionally expand the three-dimensional wiring route of the wire harness in the vehicle. Is maintained.

  The plurality of jigs 20 include, for example, a U jig 22 having an upper portion formed in a U shape. The lower part of the U jig 22 is formed in a rod shape, and is formed in a bifurcated shape as a whole. The U jig 22 can support the electric wire W at the top. Further, a branch support jig 24 formed in a trifurcation or more (in the example shown in FIG. 1, in a quadrangular shape) as a whole is erected at the branch portion. In addition, examples of the jig 20 include a connector support jig 26 that supports the connector C. The wiring jig 30 is one of a plurality of jigs 20 erected on the plate portion 12.

<Jig for wiring>
FIG. 2 is a partially exploded perspective view showing the wiring jig 30 according to the embodiment.

  The wiring jig 30 includes a main body portion 32 that can support the electric wire W or the connector C, and a holding portion 40 that can hold the end portion of the electric wire W.

  The main body portion 32 includes a drawing plate attachment portion 34 formed so as to be attachable to the assembly drawing plate 10 and a support portion 36 formed so as to be able to support the electric wire W or the connector C. Here, the jig | tool 20 conventionally used for wiring is assumed as the main-body part 32. As shown in FIG. In particular, a connector support jig 26 (also referred to as a connector frame jig or a connector holding jig) that supports the connector C is assumed as the main body portion 32 here.

  The drawing plate attaching portion 34 includes a rod-like portion 35. The figure board attaching part 34 is attached to the assembly figure board 10 as follows, for example. That is, a through-hole through which the rod-like portion 35 can be inserted is formed in the plate portion 12 of the assembly drawing board 10. A flange is provided in the middle portion of the rod-shaped portion 35, and a screw is cut in the rod-shaped portion 35 at the tip of the rod-shaped portion. Then, a nut is attached to the screw of the rod-shaped portion 35 in a state where the tip of the rod-shaped portion 35 is inserted into the through-hole of the plate portion 12 and the flange portion is caught on the periphery of the through-hole. As a result, the plate portion 12 is sandwiched between the nut and the flange portion, and the rod-like portion 35 is attached to the plate portion 12, so that the plate attachment portion 34 is attached to the assembly drawing plate 10.

  The support portion 36 is provided on the drawing plate attachment portion 34. Here, the support portion 36 is formed to be able to support the connector C. The support part 36 is formed in a rectangular parallelepiped box shape, and the support part 36 is formed with a recess 36h. The recess 36h is formed so that the connector C can be inserted. At this time, the connector C supported by the support portion 36 opens the opening of the cavity Ca. For this reason, the end portion of the electric wire W can be connected to the empty cavity Ca of the connector C in a state where the connector C is supported by the support portion 36. Thereby, the end portion of the electric wire W can be easily inserted into the connection target connector C on the assembly drawing board 10.

  But the shape of the support part 36 is not restricted to what was mentioned above. For example, the support portion 36 may be formed in a U shape similarly to the upper portion of the U jig 22. In this case, the U-shaped portion supports the portion close to the connector C among the electric wires W extending from the connector C, or the housing of the connector C is caught by the U-shaped portion with the electric wires W stretched. Then, the support portion 36 supports the connector C. In addition, as the support portion 36, a configuration in which a plate member is fitted to the U-shaped portion and the connector C is placed on the plate member, or an electric wire W extending from the connector C to a comb-shaped portion instead of the U-shape. The structure etc. which catches are also considered. In these cases, when the end of the electric wire W is connected to the connector C, the connection of the connector C by the support portion 36 may be temporarily released.

  In the example shown in FIG. 1, the support portion 36 is formed so as to be able to support one connector C, but the support portion 36 may be formed so as to be capable of supporting a plurality of connectors C.

  The holding part 40 is provided in the main body part 32. Here, the holding part 40 is formed separately from the main body part 32. The holding | maintenance part 40 is formed so that the edge part of the electric wire W can be hold | maintained. Specifically, the holding part 40 includes an end holding part 42 and a jig mounting part 46.

  The end holding part 42 is formed so as to hold the end of the electric wire W. More specifically, the end holding portion 42 includes a frame 43 and an elastic piece 44. The frame 43 is formed in a U shape using a resin or the like as a material. Hereinafter, the side having the U-shaped opening in the frame 43 may be referred to as an upper portion, and the side opposite to the upper portion may be referred to as a bottom portion. The elastic piece 44 is attached to the inner peripheral side of the frame 43 using an elastic material such as rubber. Here, the elastic piece 44 is formed with a slit 44s having a width equal to or smaller than the diameter of the electric wire W to be held. The slit 44 s reaches the upper edge of the elastic piece 44. Thereby, the intermediate part of the electric wire W can be inserted in the said slit 44s from the upper side. Then, by inserting the electric wire W into the slit 44 s, the elastic piece 44 sandwiches the electric wire W, so that the holding unit 40 holds the electric wire W.

  But the structure of the edge part holding | maintenance part 42 is not restricted to what was mentioned above. For example, the end holding part may be a part in which the resin frame directly holds the end of the electric wire W. Further, for example, the end holding portion may be one in which the terminal T is caught on the periphery of the slit of the elastic piece when the electric wire W is pulled without holding the electric wire W. Preferably, the end holding portion 42 may be configured so that the holding state of the electric wire W is not canceled even if the electric wire W is accidentally pulled when the other electric wires W are wired.

  The jig attaching portion 46 is formed to be detachably attached to the main body portion 32. Here, the jig attachment portion 46 is formed to be attachable to the rod-like portion 35. Specifically, the jig attachment portion 46 includes an extension piece 47 and an attachment piece 48. The extension piece 47 extends from the frame 43. Here, the extending piece 47 extends from the bottom of the frame 43 in a direction perpendicular to the surface on which the U-shaped frame 43 spreads. However, the extending piece may extend in other directions. The attachment piece 48 is provided at the tip of the extension piece 47. The attachment piece 48 is formed wider than the extension piece 47, and a through hole 48 h is formed in the attachment piece 48. The through hole 48h is formed so that the rod-like portion 35 can be inserted therethrough. For example, it is conceivable that the through hole 48h is formed to be slightly smaller than the rod-shaped portion 35 and the rod-shaped portion 35 can be press-fitted. The jig attachment portion 46 is attached to the rod-like portion 35 by press-fitting the rod-like portion 35 into the through hole 48h. At this time, the extending direction of the extending piece 47 around the rod-shaped portion 35 and the position of the mounting piece 48 with respect to the extending direction of the rod-shaped portion 35 are fixed.

  In the example shown in FIG. 2, the rod-like portion 35 is inserted into the through hole 48 h from the side attached to the assembly drawing board 10. In this case, it is conceivable that the through hole 48h is inserted before being attached to the assembly drawing board 10. However, for example, when the support portion 36 and the rod-like portion 35 are fastened with a screw or the like so as to be able to be released from the union, the support portion 36 of the rod-like portion 35 is attached after the rod-like portion 35 is attached to the assembly drawing board 10. It is conceivable that the rod-like portion 35 is inserted into the through hole 48h from the side to be provided.

  However, the jig attaching portion 46 may be attached by a method other than press fitting. For example, the jig mounting portion may be sandwiched between a flange portion and a nut provided on the rod-shaped portion 35. The jig attaching portion is preferably fixed and attached around the rod-like portion 35 so as not to rotate. In addition, the jig attachment portion is preferably fixed and attached so as not to move in the extending direction of the rod-like portion 35.

  Thus, the holding part 40 formed separately from the main body part 32 can also be regarded as an example of an electric wire end holding jig that can be attached to the conventional supporting jig 20 such as the connector supporting jig 26.

  In the example shown in FIG. 1, one holding part 40 is provided for one main body part 32, but a plurality of holding parts 40 may be provided for one main body part 32.

<Manufacturing method>
Next, the manufacturing method of the wire harness using the said assembly drawing board 10 is demonstrated. FIG. 3 is a perspective view showing a state in which the end of the electric wire Wa is held by the wiring jig 30. FIG. 4 is a perspective view showing a state where the connector-attached electric wire is wired on the assembly drawing board 10. FIG. 5 is a perspective view showing a state in which the end of the electric wire Wa held by the wiring jig 30 is connected to the connector C. FIG. FIG. 6 is a perspective view showing a state in which the end of the electric wire Wa held by the wiring jig 30 is connected to the connector C. FIG. In addition, in FIG. 6, the electric wire W previously inserted in the connector C is shown with the dashed-two dotted line.

  First, as shown in FIG. 1, an assembly drawing board 10 in which a jig 20 including a wiring jig 30 is arranged in accordance with the wiring form of the wire harness is prepared (step (a)). At this time, the wiring jig 30 is preferably arranged so that the holding portion 40 is positioned closer to the support portion 36 that supports the connection target connector C than the jig 20 that supports another electric wire Wb. Here, since the wiring jig 30 includes the support portion 36 and the holding portion 40, the holding portion 40 is positioned closer to the support portion 36 than the U jig 22 that supports another electric wire Wb. For this reason, it is suppressed that electric wire Wa crosses with other electric wires Wb.

  In the example shown in FIG. 3, one holding unit 40 holds the end of one electric wire Wa, but one holding unit 40 holds the end of a plurality of electric wires W. Good.

  Next, as shown in FIG.3 and FIG.4, while holding | maintaining the edge part of the electric wire Wa to the holding | maintenance part 40, the connection object connector C is wired (process (b)). Here, as shown in FIG. 3, the end portion of the electric wire Wa is inserted into the elastic piece 44 by inserting the end portion of the electric wire Wa into the slit 44 s of the elastic piece 44 while hooking the electric wire Wa on the branching support jig 24. Let At this time, the electric wire Wb is also wired while being hooked on the branching support jig 24 and the U jig 22. One end of each of the electric wires Wa and the electric wires Wb extends in a different direction with respect to the branching support jig 24 and the other ends extend in the same direction. At this time, since the end holding portion 42 is positioned on the support portion 36 side with respect to the U jig 22, the electric wire Wa and the electric wire Wb are wired without crossing. Next, as illustrated in FIG. 4, the connection target connector C is inserted into the recess 36 h of the support portion 36 of the wiring jig 30 while the electric wire W extending from the connection target connector C is hooked on the branch support jig 24. Is inserted and supported.

  Next, as shown in FIG.5 and FIG.6, the edge part of the electric wire Wa hold | maintained at the holding | maintenance part 40 is connected to the connector C for a connection (process (c)). Specifically, as shown in FIG. 5, the end portion of the electric wire Wa is removed from the slit 44 s of the elastic piece 44. Then, as shown in FIG. 6, the end portion of the removed electric wire Wa is inserted into a predetermined empty cavity Ca of the connection target connector C supported by the support portion 36. At this time, since the wire Wa and the wire Wb are wired without crossing, even if the wire Wa is directly connected to the connector C from the end holding portion 42, the wire Wa and the wire Wb are not entangled. It will be in the state. At this time, since the holding portion 40 that holds the end portion of the electric wire Wa and the support portion 36 that supports the connection target connector C are provided in the same wiring jig 30, the operator can use the end portion of the electric wire Wa. It is easy to recognize the connector C to be connected. Thereby, the erroneous insertion of the edge part of the electric wire Wa can be suppressed.

  When the wiring of the electric wire W is finished and the end portion of the electric wire Wa is connected to the connector C, the wire harness is completed by appropriately attaching and binding the exterior member and removing it from the assembly drawing board 10.

  According to the wiring jig 30 configured as described above and the method of manufacturing the wire harness using the same, the holding portion 40 that holds the end portion of the electric wire Wa includes the drawing plate attachment portion 34 and the support portion 36. By providing the main body portion 32, the holding portion 40 does not cross another electric wire Wb with respect to the support portion 36 that supports the connection target connector C even when the space for standing on the assembly drawing board 10 is small. Can be placed in position. Thereby, it can suppress that the electric wire Wa which the said holding | maintenance part 40 hold | maintains with another electric wire Wb.

  Moreover, since the support part 36 is formed so that the connector C can be supported, for example, by using the holding part 40 to hold the electric wire Wa to be inserted into the connector C supported by the support part 36, the electric wire Wa is used. However, it becomes difficult to cross with another electric wire Wb. In addition, it is possible to easily recognize the connection target connector C of the electric wire Wa to be inserted later by the operator, and it is difficult to mistake the connection destination of the electric wire Wa.

  Further, since the holding part 40 is formed separately from the main body part 32 so as to be detachable from the main body part 32, the existing U jig 22 or the connector support jig 26 can be used as the main body part 32. Thereby, it is only necessary to newly start the holding unit 40, and it is possible to suppress an increase in the number of component types and an increase in cost.

  In addition, the jig attachment portion 46 of the holding portion 40 is formed so as to be attachable to the rod-like portion 35. Usually, the figure board attaching part 34 of the existing U jig 22 and the figure board attaching part 34 of the connector support jig 26 often include a rod-like part 35. For this reason, the holding part 40 can be attached to both the U jig 22 and the connector support jig 26 with the structure of the common jig attaching part 46, and the increase in the number of types of holding parts 40 and the increase in cost are suppressed. be able to.

{Modifications}
Next, a modified example of the wiring jig 30 will be described.

  In the embodiment, it has been described that the holding portion 40 is attached to the connector support jig 26 that supports the connector C, but this is not essential. As in the wiring jig 30A according to the modification shown in FIG. 7, the holding portion 40 may be attached to the U jig 22 that supports the electric wire Wb. That is, in this case, the U jig 22 forms the main body 32A of the wiring jig 30A. At this time, the holding portion 40 may be disposed on the side close to the connector support jig 26 that supports the connection target connector C with respect to the U jig 22. Thereby, as shown in FIG. 7, it is suppressed that the electric wire Wa and the electric wire Wb cross. In the example shown in FIG. 7, the holding portion 40 is attached to the U jig 22 that supports the electric wire Wb, but may be attached to a jig 20 that supports the other electric wires W. For example, the holding part 40 may be attached to the branching support jig 24.

  In the embodiment, the jig attaching portion 46 is described as being attached to the rod-like portion 35 by inserting the rod-like portion 35 into the through hole 48h from one end side, but this is not essential. Like the jig attachment part 46B of the wiring jig 30B according to the modification shown in FIG. Specifically, the attachment piece 48B of the jig attachment portion 46B of the holding portion 40B has a groove 48s extending from the through hole 48h to the outer edge in a part of the attachment piece 48B, and is formed in a C shape as a whole. . At this time, the width of the groove 48s is set to be equal to or smaller than the diameter of the rod-shaped portion 35, and the attachment piece 48B is formed to be elastically deformable so that the width of the groove 48s is widened. Accordingly, when both ends of the mounting piece 48B sandwiching the groove 48s are pressed against the rod-shaped portion 35, the groove 48s expands, and the rod-shaped portion 35 can be passed from the groove 48s into the through hole 48h. Thereby, even if the connector support jig 26 is erected first on the assembly drawing board 10, the holding portion 40B can be attached to the erected connector support jig 26 later.

  Moreover, although the holding | maintenance part 40 was demonstrated in the embodiment as what was provided separately from the main-body part 32, this is not essential. Moreover, although the holding | maintenance part 40 was demonstrated as what is provided in the board attachment part 34 among the main-body parts 32, this is not essential.
