[Industrial applications]

 The present invention facilitates the connection between the wired wire end and the connector when the wire group is laid on the drawing jig on the drawing board to form the wire harness. The present invention relates to a wire wire temporary holding jig for wire laying, which is used to arrange and temporarily hold wires.

[0002]

[Prior Art]

 When a wire harness is formed by laying a group of electric wires, a wiring jig having a U-shaped electric wire receiving portion, which is disclosed in Japanese Utility Model Laid-Open No. 62-136015, is used. A wire harness of a required form is formed by the standing wire arranging jig, and a wire harness is formed by processing such as connecting a connector to a terminal at the wire end of the wire bundle.

In order to efficiently insert the terminals of the electric wire group into the common connector, the postures of the electric wire ends are aligned and temporarily held in correspondence with the arrangement of the terminal accommodating chambers on the connector side. After connecting to the connector, it is necessary to quickly release the temporary alignment holding posture.

Therefore, conventionally, as shown in FIG. 5, the wiring jig 10 is utilized to wind the wire end 8 around the frame bar 11 of the wiring jig 10, or as shown in FIG. Using the temporary holding jig 13 in which the coil spring 12 is horizontally fixed, the wire end 8 is inserted between the coil pitches of the coil spring 12 to temporarily hold it, or as shown in FIG. A temporary holding jig 13 composed of a holding column 15 having a holding portion 14 is used, and the wire ends 8 are sequentially inserted in a row from above the electric wire holding portion 14 to be temporarily held. The temporary holding means of is adopted.

[Problems to be Solved by the Invention] According to the above-mentioned conventional temporary holding means for the wire end, there are the following problems. That is, in the case of FIG. 5, the wire end 8 is easily disengaged from the frame bar 11, and in addition, when it is wound around the frame bar 11, the root of the terminal 17 (the intermediate portion between the contact portion and the wire crimping portion is exposed to external force). The weak part) may bend, and the connector may not be connected smoothly. In addition, in the case of the one shown in FIG. 6, the wire end 8 is easily disengaged, the small-diameter wire rattles, the large-diameter wire is difficult to insert, and it is difficult to insert the large-diameter wire into the spring. Occurs, resulting in poor electric wire holding performance and durability. Further, in the case of FIG. 7, since the clasping column 15 forms an elongated vertical beam with the lower end fixed and the upper end free, when the wire end 8 is press-fitted, the clinging column 15 elastically deforms like an open leg. Therefore, as shown in the figure, when the wire end 8A of the large-diameter electric wire is inserted first, the wire end 8B of the small-diameter electric wire that is inserted later cannot be attached.

The present invention provides an electric wire end temporary holding jig that solves the above-mentioned drawbacks of the prior art.

[0007]

[Means for Solving the Problems]

 The wire end provisional holding jig of the present invention which solves the above technical problem is that "a U-shaped holding frame having an upper end opening is formed in a skeleton portion, and the holding frame is provided inside each of the opposing frames. An air cushion portion formed of an elongated air layer extending along the inner side of the frame and elastically sandwiching the wire ends vertically between the tip portions of the air cushion portion ".

“A U-shaped holding frame having an upper end opening is formed in the skeleton portion, and sandwiching plates of elastic material sheets extending along the inside of each of the facing frames of the holding frame are arranged to face each other. The clasping plate has a base portion fixed to the facing frame, and the tip ends facing each other are joined or close to each other substantially along the longitudinal center line of the facing frame, and the wire ends are elastically aligned in a line between the cladding plates. It is composed of the second device of "Claim structure".

[0009]

[Action]

 The wire end temporary holding jig of the first invention is characterized in that the wire is held by the "air cushion part composed of the air layer" provided in the U-shaped holding frame forming the skeleton part. While the posture of the cushion portion is held by the rigid holding frame, the air layer of the cushion portion functions as an elastic floor in terms of material mechanics to form an elastic floor beam on the rigid holding frame. Therefore, this air cushion part has uniform elasticity at any of the upper and lower positions, and compresses the air layer at each position depending on the resistance of the individual wires that are stuck, and the individual wires of the sandwiched wire are compressed. A concave displacement is generated along the outer circumference of the wire to elastically attach the wire end group. Therefore, even if there is a difference in the diameters of the wires that are held together, the displacement of the air cushion part due to the large wires has very little effect on the holding of the small wires. The group enjoys a substantially even elastic clamping action by the air cushion portion, and the temporary holding posture in one vertical row is extremely stable.

In the wire end temporary holding jig of the second invention, the elastic plate material holding plates are arranged to face each other on the U-shaped holding frame forming the skeleton, and the tip ends of the pair of holding plates. Since it has the structural feature that the wire ends are held vertically in a row between the parts, as in the first invention, at each position where the wire ends are held, the holding plate extends along the outer circumference of the wire end. “Flip over” and stick together. Therefore, at almost any position on the holding plate, a substantially uniform holding force is generated according to the wire diameter, and displacement of the holding plate by the large diameter wire has very little effect on the holding of the small diameter wire. The different diameter wire group enjoys a substantially even elastic clinging action by the clasping plate, and the temporary holding posture in a vertical row is stabilized. Then, the temporary holding jig of the first and second inventions described above can collectively release the temporary holding state by pulling it downward after connecting the wire end and the connector.

【Example】

 Hereinafter, a detailed description will be given based on examples. First, referring to FIG. 1 showing an embodiment of the first invention, the wire end temporary holding jig of the present invention is a rigid metal U-shaped holding frame 1 composed of a facing frame 2A2B having an upper opening. Is formed as a skeleton portion, and inside the opposing frame 2A 2B, an air cushion portion 5A5B of a rubber elastic body made of an elongated air layer 3 which is elongated and extends along the inside of the holding frame 1 is provided. 1, the wire end 8 to be temporarily held is inserted between the pair of air cushion portions 5A5B and sandwiched, and the compression reaction force of the air layer 3 caused by the clasping force causes the wire end 8 group. Have a structure in which they are aligned vertically and held temporarily.

Specifically, the air cushion portion 5A5B of this embodiment is integrally formed with a holding frame mounting portion 7 having an insertion hole 6 into the opposing frame 2A2B, and the opposing frame 2A2B is inserted into the insertion hole 6. An air cushion portion 5A5B is attached to the holding frame 1 by inserting it, and an air cushion portion 5A5B that extends the air layer 3 along the inside of the holding frame 1 is attached. In this embodiment, the left and right air cushion parts 5A5B forming a pair are formed as a continuous one piece, and are attached from the center before being inserted into the holding frame 1. Reference numeral 4 in the drawing denotes a handle used to hold the jig by hand or to erect it.

In the wire end temporary holding jigs of the above embodiments, the air cushion portion 5A5B has an elastic floor beam structure in which the air layer 3 is interposed between the air cushion portion 5A5B and the facing frame 2A2B of the skeleton portion. Elasticity at each position in the vertical direction of the parts 5A5B becomes uniform, and a concave displacement is formed along the outer circumference of the individual wire ends 8 that are sandwiched, so that even if wire ends 8 of different sizes are adjoined, , They receive uniform elastic elasticity and the temporary holding posture becomes stable. Due to the structural characteristics, the air cushion portions 5A5B are less likely to be "damaged or settled" and can be used with high durability, and the terminal of the temporarily held wire end is not damaged or deformed.

The air cushion portion 5A5B according to the present invention is not limited to the above-described embodiment, and the air layer 3 forming the air cushion portion 5A5B is structured to communicate with outside air, and the air back pressure of the air layer 3 causes the air layer 3 to communicate. In some cases, the ends of the wires are elastically attached. Further, as for the air cushion portion 5A5B, see FIG. 2, the cross-sectional shape of the air layer 3 may be formed into a circular shape, a triangular shape, a square shape or the like, or only the air cushion portion 5A5B without the holding frame mounting portion 7 However, it may be provided directly on the facing frame 2 or may be formed of an elastic material such as a resin material other than rubber.

Next, an embodiment of the second invention will be described with reference to FIGS. 3 and 4.

Further, elastic plates made of rubber or resin, which extend along the inside of each of the facing frames 2A2B, are provided so as to face each other, and the holding plates 9A9B are fixed to the facing frame 2A2B at their bases. At the same time, the front end portion 9'is joined or close (almost 1.0 gap or less) along the vertical center line 16 of the opposing frame 2A2B. Then, the electric wire ends 8 are vertically inserted in a row between the front end portions 9'of the holding plates 9A9B, and the electric wires 8 are held by being held. The clasping plate 9A9B of this example has a thickness of 1.5 m, and the length from the base to the tip 9'is approximately 15 m.

In the temporary holding jig shown in FIG. 3, the base of the holding plate 9A9B is held by the holding frame 1 forming the skeleton, and the wire end 8 is inserted between the opposing tips of the holding plate 9A9B. Therefore, referring to FIG. 4, the tip portion 9 ′ of the clamping plate 9 </ b> A <b> 9 </ b> B easily “turns and displaces” at each portion according to the wire diameter of the wire end 8 and individually elastically clamps the wire end 8. Therefore, even if the electric wire end groups of different sizes are held together in the same group, the respective electric wire ends have the above-mentioned effect of being stably held by the substantially uniform holding force.
