DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, the cause of the twist according to the present embodiment will be described with reference to FIG. FIG. 1 is a diagram for explaining the cause of the occurrence of twisting. In particular, FIG. 1 (A) and FIG. 1 (B) are respectively a partial perspective view and a front view of a wire harness to be designed in this embodiment. is there. In this embodiment, as shown to FIG. 1 (A), a wire harness is comprised from several branch line 1b1, 1b2 each branched from the trunk line 1a and the trunk line 1a in a different direction. A support member for a wire harness such as a connector or a clamp (not shown) is also attached to the wire harness. Such a wire harness, for example, predetermined constraints on the predetermined portion of the vehicle, is-installing so as to satisfy the constraint conditions, ie for wire harness resulting from the interference of the wiring portion and the vehicle wire harness in the vehicle The In reality, the number of trunk lines 1a and branch lines 1b1, 1b2 may be larger than the number shown in FIG. 1, but here, representatively, only one trunk line 1a and two branch lines 1b1, 1b2 are provided. Is shown. In general, the trunk line 1a is thicker than the branch lines 1b1 and 1b2, but they may have the same thickness. Further, the trunk line and the branch line are names given for convenience to the wire constituting the wire harness, and may be named in reverse or other names.
[0023]
Connectors connected to electrical components (not shown) are attached to the tip ends of the trunk line 1a and the branch lines 1b1, 1b2, and various clamps (not shown) are also attached to intermediate portions thereof. When the wire harness shown in FIG. 1 (A) is viewed from the front of the wire harness , as shown in FIG. 1 (B), the branch lines 1b1 and 1b2 are in different directions, that is, with an angle difference θ, the trunk line 1a. Branch from. Further, the angle difference θ may be an angle formed by a plurality of straight lines v1 and v2 that pass through torsion action points p1 and p2 with respect to the trunk line 1a by the support member and are orthogonal to the central axis of the trunk line 1a. Such an angle difference θ is a cause of twisting of the trunk line 1a . In the present specification, the twist or the amount of twist means a change angle from a normal position when a torque is applied to an object such as a rod or a wire.
[0024]
Next, a virtual jig surface according to an embodiment will be described. FIG. 2 is a view showing a basic type of a virtual jig surface according to an embodiment of the present invention. FIG. 3 is a diagram illustrating a virtual jig surface that is twisted and deformed within a range of an allowable twist amount.
[0025]
As shown in FIG. 2, the trunk line 1 a and the branch lines 1 b 1, 1 b 2 constituting the wire harness to be designed are parallel to the central axis and along the portions defined on both side surfaces in the longitudinal direction, respectively. Virtual jig surfaces 2a and 2b1 having a predetermined width extending in a fin shape (corresponding to the main virtual jig surface and the sub virtual jig surface in claims) are set. The virtual jig surface 2b1 is set with respect to a plurality of straight lines v1 (or v2) passing through the torsion action points p1 (or p2) caused by the support member and orthogonal to the central axis of the trunk line 1a. You may think that However, in the following description, the present embodiment will be described based on the relationship between the trunk line 1a and the branch lines 1b1, 1b2.
[0026]
The virtual jig surface is set within a range of a predetermined allowable twist amount of the trunk line or the branch line, and is deformed along with the twist. For example, in a state where the trunk line or branch line is extended in a straight line without twisting, the virtual jig surface immediately extends in a strip shape along a predetermined portion on both side surfaces of the trunk line or branch line. Further, in a state where the trunk line or branch line is twisted, the virtual jig surface extends in a curved shape twisted along a predetermined portion on both side surfaces of the trunk line or branch line. In any of the above cases, the virtual jig surface is along a predetermined portion on both side surfaces of the trunk line or branch line. Although not shown here, the same applies to the branch line 1b2 and other trunk lines and branch lines.
[0027]
As shown in FIG. 3, the trunk line and the branch line can be twisted to the limit of the predetermined allowable twist amount, and the corresponding virtual jig surface 2a ′ is twisted accordingly. The allowable twist amount is, for example, the limit twist amount (rad / m) per unit length of the trunk line and the branch line. The limit twist amount per unit length is obtained by, for example, obtaining in advance a twist amount within a range in which the wire rod and the protective member constituting the trunk line and the branch line have plasticity without being damaged. To leave. By adopting such a limit twist amount, a more accurate shape of the wire harness can be designed. Note that the virtual jig surface cannot be set outside the range of the allowable torsional amount.
[0028]
A wire harness design method, manufacturing method, and assembly method using the virtual jig surface as described above will be described below. FIG. 4 is a view showing a virtual jig surface propagated from a trunk line to a branch line by the method of the present embodiment. FIG. 5 is a view showing a state in which the wire harness is developed on a flat jig plate based on the virtual jig surface shown in FIG. 4.
[0029]
At the time of design, first, the virtual jig surfaces 4a and 4b1 and 4b2 are set as described above for the trunk line 3a and the branch lines 3b1 and 3b2 constituting the target wire harness. Next, the virtual jig surfaces 4a and 4b1, 4b2 are deformed by, for example, twisting the trunk line 3a within the allowable torsion amount range as described above, while taking into account predetermined parts to be assembled and interferences. Then, as shown in FIG. 4, the portions of the virtual jig surface 4a of the trunk line 3a and the virtual jig surfaces 4b1 , 4b2 of the branch lines 3b1, 3b2 that are in contact with each other are made to be the same surface. In other words, by twisting the trunk line 3a within the range of the allowable twisting amount to form the same surface, the virtual jig surface 4a of the trunk line 3a is changed to the virtual jig surfaces 4b1, 4b2 of the branch lines 3b1, 3b2. Propagating. At this time, the trunk line 3a and the branch lines 3b1 and 3b2 are respectively on the virtual jig surfaces 4a and the virtual jig surfaces 4b1 and 4b2 that are formed on the same plane.
[0030]
The propagation as described above can be applied not only to a part of the wire harness but also to the entire wire harness . In this case, naturally, the propagated virtual jig surface grows from the same plane as the branching virtual jig surface. When forming the same surface, the trunk line 3a is basically twisted as described above, but both the trunk line 3a and the branch lines 3b1, 3b2 or only the branch lines 3b1, 3b2 may be twisted.
[0031]
Note that an allowable range may be set in the branching direction of the branch lines 3b1 and 3b2. Specifically, the design is made such that the branching direction of the branch lines 3b1, 3b2 is closer to the intended branching direction. That is, even if the branching direction of the branch line does not completely match the target direction, considering the shape of the attachment part of the wire harness, etc., by adjusting the branching direction within an allowable range, If it is possible to form the same surface, it is also added to the design options. In this way, by setting a predetermined allowable range in the branch direction of the branch lines 3b1, 3b2, the design flexibility of the wire harness that minimizes torsion at the time of assembly is widened and more practical. Increases nature.
[0032]
As described above, the wire harness designed to ride on the virtual jig surfaces 4a and 4b1, 4b2 can be unfolded straight on the flat jig plate 5 as shown in FIG. And since the wire harness is manufactured based on this, manufacturing efficiency is also improved. Moreover, such a wire harness which is prepared, since as assembled above satisfying the constraint condition site that was considered in the design, can be assembled in Re smallest screw. Further, since Re screw minimum, the shape after assembly is also stabilized.
[0033]
Thus, according to the present embodiment, by assuming the virtual jig surface as described above, it is possible to easily minimize torsion during assembly without depending on the skill level of the designer. The wire harness can be designed. In addition, since a jig surface can be assumed at the time of designing, it becomes possible to design a wire harness in consideration of work efficiency at the time of manufacture. Moreover, since the virtual jig surface as described above is developed on a flat jig plate and a wire harness is manufactured based on this, the development work is facilitated and the manufacturing efficiency is improved. . Further, the thus produced wire harness, since the so assembled so as to satisfy the constraint condition into account in the design, assembly work becomes easy, thereby improving stability after assembly. In particular, the present embodiment is strictly constraint becomes very effective applied to the wire harness-installing the vehicle under vibration many environments.
[0034]
In addition, in the said embodiment, although the relationship between a trunk line and a branch line was illustrated, this invention is applicable similarly to the wire harness which the trunk line and the supporting member, or the trunk line, the branch line, and the supporting member were mixed. . The virtual jig surface as described above can be realized by image processing using a computer, for example. In the above embodiment has illustrated a wire harness-installing in the vehicle, it is equally applicable to a wire harness-installing in electrical equipment.
