Thus, by holding the temporarily assembled or main assembly wire harness with the assembly aid, the wire harness can be transported while sufficiently protecting the electric wire.
In particular, when an elastic member is provided along the longitudinal direction of the bottom portion, the wire harness can be held while being prevented from falling off by elastically deforming the end side edges of the pair of side wall portions together, The wire harness can be easily taken out by being elastically deformed so as to open the front end side edge portions of the pair of side wall portions. For this reason, transfer of a wire harness etc. can be performed easily.

  In this case, if the portion of the elastic receiving member on the opening side of the notch is formed in a protruding shape that reduces the opening width, the electric wire is unlikely to drop off from the elastic receiving member.

  Moreover, when at least one of the bottom part and the pair of side wall parts is transparent, it is easy to recognize the state inside the assembly aid.

  Moreover, according to the manufacturing method of the wire harness assembly auxiliary tool of this invention, a notch part is formed in the side wall part of a bowl-shaped member, and an elastic receiving member is attached to this notch part. Can be easily manufactured. In particular, by changing the position and number of notches formed in the bowl-shaped member, assembly aids corresponding to various wire harness configurations can be easily manufactured.

  Hereinafter, the wire harness assembly auxiliary tool which concerns on embodiment of this invention is demonstrated. FIG. 1 is a perspective view showing a wire harness assembly aid.

  The wire harness assembly assisting tool 10 includes a holding main body 20 and an elastic receiving member 30.

  The holding main body portion 20 is formed as a bowl-shaped member having a bottom portion 22 and a pair of side wall portions 24 provided on both side portions of the bottom portion 22. Here, the bottom portion 22 is formed in a long plate shape, and a pair of side wall portions 24 are erected on both side edges of the bottom portion 22 so as to rise in a substantially orthogonal posture. Further, the width dimension (height dimension) of the side wall part 24 is set to be sufficiently larger than the width dimension of the bottom part 22. In the holding main body 20, an accommodation space is formed that can accommodate the trunk portion Wa of the wire harness W and a connector C described later.

  Further, at least one notch portion 26 is formed in the pair of side wall portions 24. The notch 26 has a size that allows the branch line portion Wb of the wire harness W to be inserted. Here, the notch 26 is formed in a substantially rectangular shape. A plurality of notches 26 are formed according to the number of branch line portions Wb branched from the target wire harness W. Moreover, each notch part 26 is formed in the position according to the branch position of the branch line part Wb branched from the wire harness W used as object. When the main wire portion Wa of the predetermined wire harness W is accommodated in the holding main body portion 20, each branch wire portion Wb can be drawn to the outside through the corresponding cutout portion 26. The notch 26 is formed, for example, by punching with a tool having a punching die having a predetermined shape.

  The holding body 20 is made of a resin such as polyvinyl chloride or polyethylene terephthalate (PET), and in particular, at least one member of the bottom 22 and the pair of side walls 24 is made of a transparent resin. It is preferable.

  Such a holding main body 20 is processed as follows. That is, as shown in FIG. 2, a bowl-shaped member 20B having a pair of side wall portions 24B provided on both side portions of the bottom portion 22B is prepared. The hook-shaped member 20B is manufactured by, for example, extrusion molding together with an elastic member 28 described later, and a common member is used regardless of the form of the target wire harness W. The member 20B manufactured by extrusion of such a resin has an advantage that it is relatively thin and can ensure a relatively excellent strength.

  And as shown in FIG. 3, the notch part 26 is formed in the side wall part 24B of the said bowl-shaped member 20B by the position according to the wire harness W used as object, and the number according to the wire harness W. As shown in FIG. Thereby, the holding body 20 is formed.

  The elastic receiving member 30 is a member provided in the notch 26, and is formed of an elastic material such as rubber or foam material (for example, sponge). The elastic receiving member 30 is attached to the notch 26 and has a function of covering the peripheral edge of the notch 26 so as not to directly contact the branch line portion Wb.

  That is, the elastic receiving member 30 has a receiving recess 32 capable of holding the branch line portion Wb. The receiving recess 32 is formed in a concave shape smaller than the notch 26. The branch line portion Wb held in the receiving recess 32 is prevented from coming into direct contact with the peripheral edge of the notch 26.

  Here, the receiving recess 32 has a configuration in which a guide portion 33, a retaining projection 34, and a holding recess 35 are connected from the opening side toward the depth direction. The guide portion 33 has a shape that expands toward the opening side of the receiving recess 32, and is configured to be smoothly inserted into the receiving recess 32 while guiding the branch line portion Wb by the guide portion 33. The holding recess 35 is formed in an opening shape that can accommodate the branch line portion Wb. With the branch line portion Wb accommodated and held in the holding recess 35, the wire harness W described later is transferred, transported, or the like. Is to be done.

  Further, the retaining projection 34 is formed at a portion on the opening side of the holding recess 35 and has a protruding shape whose opening width is smaller than the opening width of the holding recess 35 on the far side. In other words, as a whole, the portion of the elastic receiving member 30 on the opening side of the notch 26 is formed in a protruding shape that reduces (narrows) the opening width. Then, the branch line portion Wb is pressed by the retaining projection 34 while being accommodated in the holding recess 35, and is prevented from falling outside.

  The shape of the receiving recess 32 is not limited to the above example. For example, the guide part 33 may be removed, and the holding recess 35 may be a circular or substantially square hole. Furthermore, the overall shape of the receiving recess 32 may be a substantially U-shaped recess, or may simply be a shape with linear cuts. In short, various shapes that can hold a single or a plurality of electric wire groups constituting the branch line portion Wb without being brought into direct contact with the peripheral edge of the notch 26 can be adopted.

  Here, the elastic receiving member 30 is formed by processing a plate-like elastic material into the shape shown in FIG. 4 to form an elastic sheet 30B and sticking it to the peripheral edge of the cutout portion 26 of the side wall portion 24. 26.

  That is, the elastic sheet 30B is formed by forming a plate-like elastic material in a substantially rectangular shape and forming a cutout 32B that forms the receiving recess 32 in the plate-like elastic material.

  The elastic sheet 30B is attached to the notch 26 in a state of being folded in two as shown in FIGS. 4, 5A, and 5B. That is, the one side portion folded in half is attached to the inner surface side of the peripheral portion of the notch portion 26 in the side wall portion 24, and the other side portion folded in half is the outer surface side of the peripheral portion of the notch portion 26 in the side wall portion 24. Affixed to. In addition, in the notch part 26 part, the part folded in half among the elastic sheets 30B has adhere | attached.

  The elastic sheet 30B is bonded with an adhesive or the like. As the elastic sheet 30B, when an adhesive is applied to one side in advance and a release paper is pasted on the surface to which the adhesive is applied, the elastic sheet 30B is punched into a predetermined shape. This is convenient because the above-described mounting operation can be performed simply by peeling off the release paper. In this case, it is preferable to divide the release paper along the left-right center line of the elastic sheet 30B so that the center of the elastic sheet 30B can be easily aligned.

  Moreover, as shown in FIGS. 1-3, the elastic member 28, such as rubber | gum, is provided in the bottom part 22 of the said holding | maintenance main-body part 20 along the longitudinal direction. The elastic member 28 is formed by, for example, extruding simultaneously with the other part of the holding body 20.

  And during the operation | work which accommodates and hold | maintains the trunk part Wa of the wire harness W in the holding | maintenance main-body part 20, as shown in FIG. 6, the front end side edge part of a pair of side wall part 24 is made into the open state. Further, when the wire harness W is transferred or being transported, as shown in FIG. 7, the elastic member 28B is elastically deformed to close the front edge portions of the pair of side wall portions 24. The closed form is maintained manually or by a binding band or the like depending on the situation. Thereby, it is possible to prevent the wire harness W from being inadvertently dropped from the assembly aid 10.

  The elastic member 28 may be provided in a portion of the bottom portion 22 that is connected to the side wall portion 24.

  In addition, a protrusion 29 is formed on the outer surface of the side wall 24 of the holding body 20. Here, the protrusion 29 is formed in the middle in the height direction of the side wall 24 and is formed in a ridge shape along the longitudinal direction of the side wall 24.

  Then, when the assembly assisting tool 10 is inserted into the harness holder 50 described later, the protrusion 29 is brought into contact with the opening side portion of the harness holder 50 so that the assembly assisting tool 10 is deep inside the harness holder 50. (See FIG. 11).

  Such a wire harness assembly assisting tool 10 is prepared, for example, by providing the bowl-shaped member 20B, forming at least one notch 26 on the side wall of the member 20B, and attaching the elastic receiving member 30 to the notch 26. Manufactured by installing. For this reason, what is necessary is just to form the appropriate number of notch parts 26 in an appropriate position according to the form of the wire harness W, and irrespective of the form of the wire harness W, the bowl-shaped member 20B and the elastic sheet 30B can be used. . Moreover, since each notch part 26 has the same shape, it is sufficient to prepare only one type as a tool for forming each notch part 26.

  The usage example of the said wire harness assembly auxiliary tool 10 is demonstrated.

  FIG. 8 is a view showing a state in which the wire harness assembly assisting tool 10 holds the wire harness W. For example, the trunk portion Wa of the wire harness W temporarily assembled halfway is accommodated in the holding body 20. In addition, a plurality of branch line portions Wb branched from the main line portion Wa are appropriately drawn out via the elastic receiving members 30 of the respective notches 26. At this time, as shown in FIG. 7, the tip side edges of the pair of side wall portions 24 are closed as necessary. In this state, the wire harness W is appropriately transported together with the assembly aid 10 from a predetermined production line in the factory to another production line, or from a predetermined factory to another factory.

  At this time, in order to protect the terminal portion (particularly the connector portion) of each branch line portion Wb, it may be as shown in FIG. That is, another wire harness assembly assisting tool 10 provided with the notch 26 and the elastic receiving member 30 at an appropriate position is prepared, and this is arranged next to the assembly assisting tool 10 holding the trunk portion Wa. Then, the branch line portion Wb drawn to the outside from the assembly assisting tool 10 holding the main line portion Wa is appropriately guided into the other assembly assisting tool 10 via the notch portion 26 and the elastic receiving member 30, and the branch The terminal portion of the line portion Wb is stored in the holding main body portion 20. Thereby, the terminal portion (particularly the connector portion) of the branch line portion Wb is protected in the holding main body portion 20.

  FIG.10 and FIG.11 has shown the process of transferring the wire harness hold | maintained in the wire harness assembly auxiliary tool to the substantially U-shaped harness holder erected on the drawing board for wire harness assembly.

  First, as shown in FIG. 10, the assembly assisting tool 10 is inserted into the harness holder 50 so that the opening side of the assembly assisting tool 10 faces downward. At this time, the operator closes the front end side edges of the pair of side wall portions 24. Thereby, it is possible to prevent the wire harness W from falling off the assembly assisting tool 10 before the assembly assisting tool 10 is inserted into the harness holding tool 50.

  And while opening the front end side edge part of a pair of side wall part 24, the assembly auxiliary tool 10 is pushed in back. Due to gravity, the wire harness W is detached from the assembly aid 10 and dropped into the harness holder 50.

  At this time, when the assembly assisting tool 10 falls deeply into the harness holder 50, the front side edges of the pair of side wall parts 24 are closed so as to follow the U-shape, and the wire harness W becomes the assembly assisting tool. It becomes difficult to leave 10. However, in this assembly assisting tool 10, the protrusions 29 of the pair of side wall parts 24 abut against the opening side edge of the harness holder 50, and the assembly assisting tool 10 is prevented from dropping deep into the harness holder 50. is doing. Thereby, the front end side edge part of a pair of side wall part 24 is prevented inadvertently closing in the harness holder 50.

  In order to ensure that the protruding portion 29 comes into contact with the opening side edge of the harness holder 50, the outer width dimension of the assembly assisting tool 10 is substantially the same as the inner width dimension of the harness holder 50. Preferably there is.

  Further, the assembly assisting tool 10, for example, arranges the electric wire in the holding main body portion 20 along the longitudinal direction thereof, and leads it out from the notch portion 26 and the elastic receiving member 30 as appropriate. By binding, it can also be used for temporary assembly of the wire harness W. Moreover, it can also be used as a jig for performing terminal processing such as connector attachment on each branch line portion Wb led out to the outside while keeping the wire harness W in a fixed form.

  In addition, when assembling the wire harness W, it can be used for various purposes.

  According to the wire harness assembly assisting tool 10 configured as described above, for example, the trunk portion Wa of the temporarily assembled or main assembly wire harness W is accommodated in the holding main body portion 20 and each branch portion Wb is accommodated. The wire harness W can be held in a certain form by being pulled out from the elastic receiving member 30 of the notch 26. And in the state which hold | maintained the wire harness W in this way, processing, such as connector attachment, can be given to each branch line part Wb, and the wire harness W can be transferred, conveyed, etc. Furthermore, while passing each branch line part Wb of the wire harness W through the elastic receiving member 30 of the notch part 26, the end part of each branch line part Wb was accommodated in the holding | maintenance main-body part 20, and the wire harness was hold | maintained. The wire harness W can be transported in the state. Therefore, the wire harness W can be transported or the like while sufficiently protecting the electric wire by holding the temporarily assembled or main assembly wire harness W with the assembly aid.

  In addition, since the portion of the elastic receiving member 30 on the opening side of the cutout portion 26 is formed in a protruding shape that reduces the opening width (prevention protruding portion 34), the branch line portion Wb extends from the elastic receiving member 30. It is hard to drop off.

  Furthermore, since the elastic member 28 is provided in the bottom part 22 along the longitudinal direction, the wire harness W is prevented from falling off by being elastically deformed so as to close the front side edges of the pair of side wall parts 24. The wire harness W can be easily taken out by being elastically deformed so as to open the distal end side edge portions of the pair of side wall portions 24. For this reason, transfer of the wire harness W etc. can be performed easily.

  Further, when at least one of the bottom portion 22 and the pair of side wall portions 24 is transparent, it is easy to recognize the state inside the assembly aid. In particular, when the wire harness W is transferred to the harness holder 50, it is convenient to check whether the wire harness W has fallen into the harness holder 50 smoothly and smoothly.

  Moreover, in such an assembly assisting tool 10, by using the common bowl-shaped member 20B or the like, the position or number of the notch portions 26 formed in the member 20B is changed according to the form of the wire harness W.
