Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a convergence or wiring jig that is fixed on a wiring plate for manufacturing a wire harness and is used for manufacturing a wire harness.

[0002]

[Prior Art]

 FIG. 4 is a schematic perspective view showing a jig for manufacturing a wire harness (JP-A-2-65008).

In this manufacturing jig, the wiring jig 3 is fixed at a predetermined position on the wiring plate 1. The wiring jig 3 includes a base portion 5 and a fork portion 7. As shown in FIG. 5, the base portion 5 is provided with a fixing notch 9 and is fixed to the wiring board 1 by a structure in which a bolt 11 is passed through the notch 9. The fork portion 7 has a plurality of electric wire hooks 8 protruding from the tip side of the base 5, and the electric wire hooks 8 have a U-shaped opening 10 at the upper side. Then, a plurality of electric wires 13 can be inserted into the opening 10 of the electric wire hooking portion 8 of the fork portion 7, hooked to the electric wires 13 and wired, and the tape 15 can be wound to form the wire harness in a predetermined shape.

Further, as a proposal for improving the slack of the method of converging the electric wire by such a wiring jig, there is one disclosed in Japanese Patent Laid-Open No. 57-53009.

This method is a method of interposing a flexible sheet material with an adhesive at the wire harness converging point, and thereby prevents loosening of the electric wire.

[0006]

[Problems to be solved by the device]

 However, in the former case, as shown in FIG. 5, when the number of the electric wires 13 increases, the electric wires 13A may protrude from the tip of the fork portion 7. Each electric wire 13 is pulled with a predetermined tension, and length accuracy at the time of completion is required. Due to this tension, the protruding electric wire 13A is stretched between the wiring jigs 3 as shown in FIG. 6, and when the tape 15 is wound around in this state, the electric wire 13A protrudes. When I notice it, the length of the electric wire 13A is insufficient, and eventually the work is redone.

In the former case, as shown in FIG. 7, the opening 10 has a large U-shape so that the electric wire 13 can be easily inserted or inserted. There is no problem if you do this, but as shown in FIG. 8, when laying the wires 13, one or two wires 13A pop out from the U-shaped opening 10 or stick out, or There was a problem that the work was troublesome because the worker manually re-converged it at the final tape winding stage at that time.

Further, in the latter case, although there is an effect of preventing sagging, it is necessary to interpose a sheet-like object, so that there is a problem that the cost is increased and the work is troublesome.

In view of the above, the present invention provides a converging jig capable of suppressing the wires from protruding or coming apart while maintaining the ease of inserting or easing the wires without making the cost expensive and the work troublesome. For the purpose of providing.

[0010]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a converging jig having a base portion fixed on a wiring board for manufacturing a wire harness, and a wire hooking portion having an opening above the base portion. The wire hook comprises a flange formed with a V-shaped space that extends upward and outward from the opening, and a circular link-shaped main body, and the wire hook has a predetermined opening. The configuration is such that adjustment means capable of adjustment is provided.

[0011]

[Action]

 Since the opening has a V-shaped shape that widens upward, the wire can be easily inserted or inserted through the wide upper opening. Further, after the insertion, since the lower part of the opening is V-shaped, it is narrowed, so that the electric wire is prevented from jumping out from there. After the convergence, it can be adjusted so that the opening interval can be widened against the elastic force of the spring or the like, so that it can be freely removed from the widened opening.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

First, the configuration will be described. In the converging (also referred to as wiring) jig 3, an electric wire hooking portion 21 having an upper opening 20 is formed on the same base portion 5 as in the conventional case. The opening 20 has a V-shape that extends upward and outward when viewed from the direction of the wire 13 (arrow X). That is, the shape is such that the obtuse angle A formed by the flange portion 20a is about 120 °, the width (receiving width of the electric wire 13) B is about the same as the diameter of the circle of the hanging portion 21 (described later), and the narrowest interval. (Dimension in which the electric wire 3 can be inserted) 22 is provided. The electric wire hooking portion 21 further includes a main body 23 and a circumferential portion 24 so as to form a circular ring shape having a diameter similar to that of a conventional V-shaped width when viewed from the direction of the arrow X. Have. The main body 23 receives the 3/4 circumference, and the portion 24 receives the ¼ circumference. Both are connected by a pin 25 directly below the center so that they can be folded at their respective bases 22a and 24a. .. The main body 23 and the portion 24 are provided with a spring 26 that acts in a toggle manner so that the main body 23 and the portion 24 can be in two states, that is, the circumferential holding state of FIG. 1 and the circumferential releasing state of FIG. Is connected to the main body 23 by a pin 28 and the other end is connected to one end of the spring 26, and one end is connected to the part 24 by a pin 30 and the other end is connected to the other end of the spring 26. The adjusting means 31 including the second lock lever 29 is provided. In FIG. 2, reference numeral 32 denotes a convergent electric wire, that is, a wire harness.

Next, the operation of the above embodiment will be described. As shown in FIG. 1, when the wire 13 is inserted into the wire hook 21 in the direction of the arrow Y due to the converging wiring, the opening 20 is widened in a V shape, and therefore, it is slightly displaced from the center. However, it is guided by the flange portion 20a inclined in the V shape, passes through the space 22, and enters the hanging portion space 21a. Therefore, the electric wire 13 can be easily inserted or inserted as in the conventional case.

Next, after inserting several wires 13 (FIG. 1 shows one wire, it is assumed that there are several wires), and then inserting another wire from above for wiring. However, the several electric wires 13 that have already been inserted are prevented from jumping upward because the gap 22 between the openings 20 is narrow. In other words, the plug-in wire does not stick out or pop out, preventing the wire from coming loose.

When the electric wires are converged and taken out from the jig as a wire harness after the wiring is finished, as shown in FIG. 2, the portion 24 of the electric wire hooking portion 21 is attached to the main body 23 and the clock is centered around the pin 25. Rotate around. Then, the spring 26 acts as a toggle and becomes a substantially linear shape beyond the dead point, so that the first lock lever 27 and the second lock lever 29 both rotate and release the lock, releasing the circumference of FIG. Then, the opening 20 is opened wide. Therefore, the wire harness 22 can be easily taken out from the hanging space 21a (direction of arrow Z). In addition, it can be easily reattached for complementation, and can be attached and detached automatically.

FIG. 3 shows another embodiment. In this embodiment, an electric wire hooking portion 21 having a V-shaped opening 20 similar to that of the above embodiment is formed of a material such as resin in the same shape as left-right symmetry with respect to a vertical straight line YY. Is.

In this case as well, the wires can be easily inserted as in the previous embodiment, and the wire harness 32 can be attached and detached laterally (laterally) by the elasticity of resin or the like when the wire harness 32 is attached and detached after the winding of the convergent tape. ) Direction (arrow C-C), the opening 20 can be widened, which is easy. In this case, there is no equivalent to the means 31 of the previous embodiment, but its function is also served by the elastic (flexible) member of the wire hooking portion 21.

[0019]

As described above, the converging (wiring) jig of the present invention prevents the electric wire from sticking out, sagging, or loosening, and has the additional effect of facilitating the winding of the converging tape.
