Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a wire harness corrugating jig used for winding a wire harness with a corrugated (bellows-shaped protective tube).

[Related Art] In a conventional wire harness, a corrugated wire is inserted by manually pushing the harness into the corrugated wire.

Therefore, there are drawbacks such as a painful hand and a long working time, and the harness coating is damaged at the edge of the slit of the corrugate, thereby deteriorating the quality.

In general, various jigs for inserting a wire cable and a corrugate are known. For example, in Japanese Utility Model Laid-Open No. 1-93907, a slit is pushed and expanded with a V-shaped blade, and the cable is inserted while pushing the cable with a roller. A jig is disclosed. However, in the known technique, the cable is suppressed by the roller, so that the connector is attached,
It is difficult to work when there is a branch.

Further, Japanese Utility Model Application Laid-Open No. 56-152015 discloses a working tool for opening a slit of a corrugated tube using a guide tube and inserting a wire bundle. However, such known techniques require a considerable amount of force in the insertion operation and cannot be applied to cables having connectors or branches.

[Problem to be Solved by the Invention] Accordingly, an object of the present invention is to provide a wire harness corrugating jig which can relatively easily attach and detach the wire harness and can easily push the wire harness into the corrugate. To be.

[Means for Solving the Problems] According to the present invention, in a wire harness corrugating jig used for winding a wire harness with a corrugate, the jig guides a harness (c) to one end. The guide means (1) comprises a cylindrical portion (2) having a first slit (4) extending in the axial direction on one side; A second slit (5) extending in a direction orthogonal to the first slit (4) is formed in the cylindrical portion (2).
A long hole (6) is provided in the slit (5) continuously in the axial direction, and a slope portion (7) is formed on the grip portion (8) side of the edge of the long hole (6). A triangular guide piece (10), which is long in the axial direction, is provided on the opposite side of the elongated hole (6) of the cylindrical portion (2), and the triangular guide piece (10) has a triangular base. It is located in the section (2), and its tip protrudes from the tubular section (2).

[Explanation of Operation and Effect] Therefore, the wire harness is inserted into the cylindrical portion through the first and second slits. For example, when there is a terminal, the terminal is located on the distal end side of the tubular body, and the wire harness enters from the distal end and comes out of the elongated hole. Then, when the triangular guide piece is inserted into the slit of the corrugate from the tip of the corrugate, the slit of the corrugate is pushed open, and the tip of the tubular portion is inserted into the inner hole of the corrugate. In this state, if one side of the guide piece is brought into contact with the peripheral wall of the corrugate and the jig is moved, the wire harness is automatically inserted into the corrugate. At this time, the wire harness is smoothly guided into the cylindrical portion by the long hole and the slope, and is not damaged.

Therefore, according to the present invention, the wire harness can be easily inserted into the corrugate irrespective of the presence or absence of the terminal, and can also be inserted from the middle of the corrugate. Since the guide piece is formed in a triangular shape, the size is reduced, which can be used for guidance.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a winding jig A is made of, for example, a mechanical nylon or polypropylene bar (eg, an outer diameter of 20 mm and a length of 200 m).
m) is machined to form a guide means generally indicated by reference numeral 1 at one end and a grip portion 8 at the other end, and a grip portion 9 of the grip portion 8
The knurls 9a are machined into narrow anti-slip grooves.

The guide means 1 is formed as a whole in a cylindrical portion 2 having an outer diameter D / inner diameter d of, for example, 8 mm / 5 mm and a length of, for example, 60 mm. Have been.

On one side of the tubular portion 2, a width W is, for example, 3 mm and a length L1.
For example, a first slit 4 of 20 mm is engraved. In FIG. 2, a second slit 5 having a width W1 of, for example, 3 mm which is continuous with the first slit 4 and is orthogonal to the left is formed. A long hole 6 continuous with the second slit 5 and extending in the axial direction is formed. The long hole 6 has a radius R of, for example, 2.5 mm centered on the position of the end of the first slit 4, that is, the position of the length L 1 from the tip of the cylindrical portion 2, and has a length L 2
Is formed, for example, at 9 mm, and a slope portion 7 for guiding a harness having a length L3 of, for example, 15 mm from the opposite edge of the elongated hole 6 is formed on the grip portion 8 side.

On the other hand, a guide piece 10 is adhered in the axial direction on the side facing the long hole 6 of the cylindrical portion 2.

In FIG. 3, the guide piece 10 is made of the same material as the jig A, and the cylindrical part 2 side is, for example, a bottom side of a length L4 of 27 mm, the tip part protrudes from the cylindrical part 2, and is formed in a scalene triangle. ing. The thickness T on the joining side is, for example, 7 mm, the thickness T1 on the apex side is, for example, 2 mm, and the thickness T2 is on both sides.
Is formed, for example, to be about 1 mm.

When winding the harness with a corrugate, the harness C connected to the terminal E is inserted through the first and second slits 4 and 5 of the jig A into the long hole 6 as shown in FIG.

Next, the grip part 9 of the jig A is gripped, the slit B1 of the corrugate B is pushed and expanded by the guide piece 10, and the jig is moved while the long side of the guide piece 10 is in contact with the peripheral wall of the inner hole B2 of the corrugate B. Pull A toward you. Then, harness C
Is automatically inserted into the inner hole B2 of the corrugate C from the inner hole 4 of the jig. In the case where there is no terminal E and the harness C is a single unit, the end of the harness C is fixed to the end of the tubular portion 2 with an adhesive tape or the like.

[Effects of the Invention] As described above, according to the present invention, the following excellent effects can be obtained.

(A) The wire harness can be inserted from the middle of the corrugate by the triangular guide piece, and one side also serves as a guide, so that the insertion is easy.

(B) The combination of the elongated hole and the slope portion makes it easy to insert the wire harness and does not damage the wire harness.

(C) Smooth insertion is possible regardless of the presence or absence of a branch portion or terminal of the wire harness.
