2. Description of the Related Art When a wire harness is formed by arranging a group of electric wires, a wiring jig having a U-shaped electric wire receiving portion disclosed in Japanese Utility Model Laid-Open Publication No. 62-136015 is used.
A wire bundle of a required form is formed by a wiring jig erected on the drawing board, and a process such as connection of a connector to a terminal at a wire end of the wire bundle is performed to form a wire harness.

In order to efficiently insert the terminals of the group of wires into a common connector, the ends of the wires are aligned and temporarily held in accordance with the arrangement of the terminal receiving chambers on the connector side. After connecting with the connector, it is necessary to quickly release the temporary holding posture.

Therefore, conventionally, as shown in FIG.
The wire end 8 is wrapped around the frame bar 11 of the wiring jig 10 by using the wire holding jig, or as shown in FIG. The wire ends 8 are inserted and temporarily held between the coil pitches of the springs 12, or as shown in FIG.
A temporary holding jig 13 composed of a holding column 15 having a wire is provided, and the wire ends 8 are sequentially inserted in a line from above the wire holding portion 14 and inserted and temporarily held. Has been adopted.

[Problems to be Solved by the Invention] According to the conventional wire end temporary holding means described above, there are the following problems. That is, in the case of FIG.
1 and, when wound around the frame bar 11, the root of the terminal 17 (the middle portion between the contact portion and the wire crimping portion, which is weak against external force) may be bent. In some cases, it cannot be done smoothly. In the case of FIG. 6, the wire end 8 is easily detached, the thin wire is loose, the large wire is difficult to insert, and the spring is set by forcibly inserting the large wire. Inferior in electric wire holding performance and durability. Further, the one shown in FIG.
Forms an elongated vertical beam having a fixed lower end and a free upper end. When the wire end 8 is press-fitted, the clamping column 15 is elastically deformed into an open leg shape. Therefore, as shown in the drawing, when the wire end 8A of the large diameter wire is inserted first, the wire end 8B of the small diameter wire inserted later cannot be clamped.

The present invention provides a wire end temporary holding jig which solves the above-mentioned disadvantages of the prior art.

[0007]

The wire end temporary holding jig according to the present invention which solves the above technical problem is composed of a frame having a U-shaped holding frame having an upper end opening and a frame facing the holding frame. A structure in which an air cushion portion formed of an elongated air layer extending along the inside of the opposed frame is provided inside each of the above, and the ends of the electric wires are elastically clamped vertically in a row between the tip portions of the air cushion portion. " The first idea of

[0008] A U-shaped holding frame having an upper end opening is formed as a skeleton portion, and a holding plate of an elastic material sheet extending along the inside of each of the opposing frames of the holding frame is disposed to face each other. The clamping plate has a base fixed to the opposing frame, and the opposing distal end is joined or approached substantially along the vertical center line of the opposing frame, and the ends of the wires are elastically arranged vertically in a row between the clamping plates. Structure to clamp "
It consists of the second device.

[0009]

The wire end temporary holding jig of the first invention is characterized in that it has a structure in which the wires are clamped by an "air cushion portion composed of an air layer" provided in a U-shaped holding frame forming a skeleton. The posture of the air cushion portion is held by a rigid holding frame, and the air layer functions as an elastic floor due to material dynamics, and forms an elastic floor beam on the rigid holding frame. Therefore, this air cushion portion has uniform elasticity at any point in the vertical position, compresses the air layer at each position in accordance with the resistance of each pinched electric wire, and separates each outer periphery of the pinched electric wire. A concave displacement is generated along the line to elastically clamp the wire end groups. Therefore, even if there is a difference in diameter between the electric wires to be clamped at the same time, the displacement of the air cushion portion by the large-diameter electric wires has very little effect on the clamping to the small-diameter electric wires. With the air cushion portion, a substantially equal elastic clamping action is enjoyed by the air cushion portion, and the temporary holding posture in a vertical line is extremely stable.

In the wire end temporary holding jig of the second invention, a holding plate made of an elastic sheet material is opposed to a U-shaped holding frame forming a skeleton, and the front ends of the pair of holding plates are provided. It has a structural feature in which the ends of the wires are sandwiched vertically in a row between the parts, so that, as in the first invention, at each portion where the ends of the wires are sandwiched, the holding plates extend along the outer periphery of the ends of the wires. "Fold up" and clamp. Therefore, at any position of the holding plate, a substantially equal holding force corresponding to the wire diameter is generated, and the displacement of the holding plate by the large diameter wire has little effect on the holding of the small diameter wire. The different-diameter electric wire group enjoys a substantially equal elastic clamping action by the clamping plate, and the vertical temporary holding posture is stabilized. And the temporary holding jig of the above first and second inventions,
After the connection between the wire end and the connector, the temporary holding state can be released collectively by pulling it down.
