BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling support for supporting an electric wire when assembling a wire harness.

[0002]

2. Description of the Related Art In general, a wire harness includes a wiring board on which an assembly diagram of the wire harness after assembly is drawn, and a plurality of assembling supports arranged on the wiring board along the assembly diagram. It is assembled using an assembly drawing board having and. To assemble a wire harness, a plurality of electric wires cut into a predetermined length are received by an assembling support and wired on a wiring board. As a result, a branch-shaped electric wire bundle is formed according to the assembly diagram. Then, in order to prevent the bundle of electric wires from coming apart, a tape or the like is wrapped around the outer periphery, and finally, accessory parts such as clamps and protectors are attached.

By the way, each of the assembling supports is a support fixed to a wiring board, and an electric wire support provided with an upper end of the support and a substantially U-shaped receiving portion for receiving an electric wire. And have. It is preferable to set the inner width dimension of the receiving portion of the electric wire supporting portion according to the thickness of the bundle of electric wires to be received. That is, when the electric wire diameter of the electric wire to be received is large and the number of electric wires is large, the electric wire bundle becomes thick, and accordingly, the inner width dimension of the receiving portion is increased accordingly. On the other hand, when the diameter of the electric wire is small and the number of electric wires to be received is small, the electric wire bundle becomes thin, and accordingly, the inner width dimension of the receiving portion is reduced accordingly. This is preferable because no gap is formed between the wire bundle and the receiving portion and the wire bundle can be received well.

[0004]

However, in the conventional assembling support, the inner width dimension of the receiving portion and the length dimension of the column are fixed. Therefore, there are the following problems. If you want to match the inner width of the receiving part to the thickness of the bundle of electric wires to be received, prepare a large number of assembling supports in stock that have an inner width dimension that matches the diameter of each electric wire bundle to be received. I have to go.

Depending on the specifications of the wire harness to be assembled, it may be necessary to strictly adhere to the height dimension from the wiring plate surface to the receiving portion.

Conventionally, an assembling support tool as disclosed in JP-A-2-65008 has been provided.

In this supporting tool for assembly, a pair of movable elements with pins for supporting the bundle of electric wires can be driven by a rack and pinion mechanism or a screw mechanism to widen or narrow the distance between them. Thus, it is possible to adapt the thickness of the supported wire bundle. However, such a rack and pinion mechanism or a screw mechanism has a complicated structure, which increases the manufacturing cost of the assembling support.

Since the receiving portion is substantially U-shaped,
The wire bundle can be supported but cannot be held in the receiving portion. For this reason, the electric wire supported by the receiving portion may fall off during the wiring work, and the dropped electric wire must be returned to the receiving portion again each time.
Therefore, in view of the above problems and the first problem of the present invention

A plurality of small holes 44 (six in this embodiment) similar to the small holes 14 and 24 are provided on the peripheral surface of the reinforcing pipe 40.
The connecting pin 30 can be inserted even when 0 is attached.

Focusing on FIG. 1, above the large diameter portion 22 of the second support portion 20, a large diameter portion 2 formed in a crank shape is formed.
A crank portion 25 made of a round bar having a diameter smaller than 2 is integrally provided. Explaining in detail, this crank part 2
5 has an extended portion 25a continuous with the large diameter portion 22 and a substantially L-shaped L-shaped portion 25b extended in the extended portion 25a. The L-shaped portion 25b constitutes a part of a receiving portion U of the electric wire supporting portion A2 described later. Further, the extension portion 25a is provided with a screw hole 26 in which a female screw is formed, and the small diameter portion 61a of the slide pin 61, which will be described in detail later, is screwed into the screw hole 26.

Next, the electric wire support portion A2 will be described.
The electric wire support portion A2 includes the crank portion 25, a slide member 50 that slides on and off the crank portion 25 (as indicated by a chain double-dashed line in the figure), and a slide member that slides the slide member 50. Rotation for opening / closing the mechanism 60, the coil spring 62 for urging the slide member 50 toward the crank portion 25, and the open end portion of the U-shaped receiving portion U formed by the crank portion 25 and the slide member 50. And a lever 70.

The slide member 50 and the crank portion 25 form a pair. When the slide member 50 slides horizontally with respect to the crank portion 25, the distance between the two changes, whereby the electric wire can be clamped and received. The slide member 50 is formed in a crank shape, and has a slide portion 51 and a substantially inverted L-shaped extension portion 52 extending from the slide portion 51. That is, the receiving portion U is formed by the inverted L-shaped extending portion 52 and the L-shaped portion 25b of the second support portion 20.

The slide mechanism 60 includes a through hole indicated by reference numeral 51a and a slide pin indicated by reference numeral 61. The through hole 51a is provided in the slide portion 51,
It has a rectangular shape. The slide pin 61 is inserted into the through hole 51a. Slide pin 61
Is a stepped bolt having a small diameter portion 61a and a large diameter portion 61b. The large diameter portion 61b has a quadrangular cross section and is engaged with the through hole 51a. Also,
A male screw is formed on the small diameter portion 61a and is screwed into a screw hole 26 formed in the extending portion 25a of the second support portion 20. A lock nut N3 is hooked on the tip of the small diameter portion 61a.

The coil spring 62 is fitted into the large-diameter portion 61b of the slide pin 61, and is disposed between the head of the slide pin 61 and the slide portion 51 via a washer 63. As a result, the slide member 50 is always elastically biased toward the crank portion 25, that is, in the direction of narrowing the inner width dimension of the receiving portion U, and the width of the receiving portion U is the largest when the electric wire is not received. It is designed to be narrow.

The rotating lever 70 can be constituted by, for example, a round bar member, and one end portion 71 thereof is supported by the tip portion of the extending portion 52 of the slide member 50. More specifically, a pair of opposed plates 52a is provided at the tip of the extended portion 52. The one end portion 71 of the rotating lever 70 is rotatably supported by the pair of opposed plates 52a via a rotating pin 72.

Further, a finger hooking portion 71a is formed on the one end portion 71, and the restriction is released by hooking a finger on the finger hooking portion 71a and turning the turning lever 70 (a state indicated by a chain line). be able to. This allows
The electric wire bundle received by the receiving portion U can be taken out.

According to this embodiment, by grasping and pulling the slide member 50 with a hand, the interval between the receiving portions U is expanded (the state shown by the chain double-dashed line in FIG. 1). Then, after inserting the electric wire included in the wire harness to be assembled between the receiving portions U and releasing the hand, the coil spring 62
The slide member 50 urged by the L-shaped portion 25b
It is urged to move to the side. Thereby, the electric wire is clamped. By repeating this operation, the bundle of electric wires can be held between the receiving portions U. In this case, the slide member 5
Since 2 is elastically biased, the inner width dimension of the receiving portion U can be changed according to the thickness of the bundle of electric wires to be clamped, and the bundle of electric wires can be clamped.

Therefore, even if the specification of the wire harness changes and the thickness of the wire bundle to be supported changes, the wire harness can be favorably supported without a gap between the wire bundle and the receiving portion U. It is possible to provide the support tool A which can be adapted to the assembly work of the wire harnesses of a plurality of types even with the support tools A of the above types. As a result, it is not necessary to stock a plurality of types of supports in advance, and maintenance of the supports is facilitated. Moreover, the support A has a simple structure in which the slide member 52 slides along the slide pin 61, so that the support A can be manufactured at low cost.

Particularly, in this embodiment, the following operational effects are further exhibited. Since the slide member 50 is guided by the slide pin 61 and smoothly slides toward the crank portion 25 side, the wiring work of the electric wire can be smoothly performed. Since the slide pin 61 is engaged with the rectangular through hole 51a, it is possible to prevent the slide member 50 from rotating around the slide pin 61 during sliding. As a result, once the slide member 50
Even if the user releases the hand after widening the gap of the receiving portion U by sliding the electric wire, the electric wire can be reliably held between the slide member 50 and the crank portion 25, and the wiring work can be performed more smoothly. You can

The desired small holes 14 and 24 are selected from the plurality of small holes 14 and 24 provided in the first strut portion 10 and the second strut portion 20, and the positions thereof are aligned to form the connecting pin 3.
By connecting with 0, the length in the longitudinal direction of the column A1 can be adjusted. Therefore, the height dimension from the wiring board B to the receiving portion U can be determined according to the specifications of the wire harness to be assembled. Thereby, even one type of support tool A can be adapted to the assembly work of the wire harness of a plurality of types of specifications. As a result, it is not necessary to stock a plurality of types of supports in advance, which makes it easier to maintain and manage the supports.

The reinforcing pipe 40 can improve the strength of the connecting portion between the first support column 10 and the second support column 20. Therefore, a thick and heavy wire bundle can be supported. By rotating the rotating lever 70 to close the open end of the receiving portion U, the electric wire once received is received.
Can be prevented from falling off. This allows
When the once-supported electric wire falls off from the receiving portion U, smoother wiring work can be performed without the troublesome work of reinserting the electric wire into the receiving portion U. On the other hand, by rotating the rotating lever 70 (see FIG.
In the state shown by the middle dashed line), the wire bundle can be taken out from the receiving portion U.

The present invention is not limited to the above embodiment, and the following modifications can be considered. First Modified Example FIG. 4 is a partial cross-sectional front view of the electric wire support portion A2 showing a first modified example. With reference to FIG. 4, the difference between the first modification and the above-described embodiment is that the extending portion 25a of the crank portion 25 has an L-shaped portion 25.
b, a receiving rod 25c is provided on the opposite side, a slide member 50 is provided with an insertion hole 50a into which the receiving rod 25c is inserted, and a slide pin 65 is a hexagon bolt. Cage,
The sliding member 50 is provided with a round through hole 51b. Since the other configurations are similar to those of the above-described embodiment, the same reference numerals are given and the description thereof is omitted.

According to the first modification, the receiving rod 25c constitutes the bottom of the receiving portion U even when the slide member 50 slides. As a result, even if the slide member 50 slides to receive the thick bundle of electric wires, the electric wires included in the bundle of electric wires can be connected to the L-shaped portion 25b and the slide member 5.
It does not fit in between 0. Therefore, the wiring work of the electric wire can be performed more smoothly.

Further, in the above embodiment, the slide member 50 is used.
The rotation is regulated by the square through hole 51a and the slide pin 61 having the large diameter portion 61b having a square cross section which engages with the through hole 51a. However, by inserting the receiving rod 25c into the insertion hole 50a. , Slide member 50
The rotation around the slide pin 65 can be restricted. As a result, the same effect as that of the above embodiment can be obtained. Further, the slide pin 65 has an advantage that a general-purpose hexagon bolt can be used. However, as in the above-described embodiment, the through hole 51b may be formed in a polygonal shape, and the slide pin 65 may be formed in a polygonal cross section that engages with the through hole 51b.

Second Modified Example FIGS. 5 and 6 show a second modified example of the electric wire support portion A.
2 is an enlarged view of an open end portion of the receiving portion U of FIG. 2, FIG. 5 is a front view, and FIG. 6 is a plan view. Referring to FIGS. 5 and 6,
The second modification is different from the above embodiment in that a hole 75 having a predetermined depth is formed in the upper end surface portion 52d of the extending portion 52 of the slide member 50. One end portion of the rotating lever 70 A pivot pin 76 inserted into the hole 75 is formed at 71. A pivot lever 70 closes the open end of the receiving portion U at the tip portion 25d of the L-shaped portion 25b of the crank portion 25. A concave portion 78 into which the tip portion 77 of the rotating lever 70 enters when the posture is set to "1" is formed. Since the other configurations are similar to those of the above-described embodiment, the same reference numerals are given and the description thereof is omitted.

According to this second modification, the rotating lever 7
0 is rotatable about the rotating pin 76 in the direction shown by the arrow in FIG. As a result, the rotation lever 7
When 0 is in the posture shown in the figure, the falling of the electric wire received in the receiving portion U can be regulated, and in the posture shown by the alternate long and short dash line in FIG. It can be taken out from the part U. Therefore, also in this second modified example, the same effect as that of the above-described embodiment is obtained. Moreover, when the turning lever 70 is in the posture of restricting the falling of the electric wire, the tip end 77 of the turning lever 70 enters the recess 78, so that the turning lever 70 may come off the slide member 50. There is no.

As a modification of the design of the second modification, as shown in FIGS. 7 and 8, the rotation lever 70 may be lengthened so as to penetrate the recess 78. Even in this case, the same operational effect as that of the second modification can be obtained. Third Modified Example FIG. 9 is an enlarged front view of the open end portion of the receiving portion U of the electric wire support portion A2, showing a third modified example.

Referring to FIG. 9, the third modification is different from the above embodiment in that the L-shaped portion 25b of the crank portion 25 is different.

As described above, also in the third modification, the same effect as that of the above-described embodiment is obtained. Moreover, since the rubber plate 79 is used as a means for controlling the dropping of the electric wire,
There is an advantage that the support tool A can be manufactured at a lower cost.

Further, in the above-mentioned embodiment and each of the modified examples, a part of the electric wire supporting portion A2, that is, the crank portion 25 is formed integrally with the second supporting portion 20 of the supporting column A1. Then, the column A1 and the electric wire support portion A2 can be separately configured.
