Abstract

PURPOSE:To improve the appearance of a wire harness and wiring property in a narrow part by converging the electric wire's looseness caused on a bundled electric wire on a protector and fixing the base part of the looseness. CONSTITUTION:A bundled electric wire 3 (a base wire 3a and divided wires 3b) is wired on supporting pins 2 of a harness spread wiring board 1. At the same time, a protector 4 made of a synthetic resin is set in the middle part of the bundled electric wire 3 by using a mounting stand 6. An adhesive vinyl tape 5 are coiled on the bundled electric wire 3 from both end parts of the bundled electric wire 3 to the protector 4. Then, the looseness of the base wire 3a and the divided wires 3b is converged to the protector 4, following the coiling of the tape. By this way, the looseness of the electric wire can be converged on the protector, so that the appearance of the harness becomes good and the production value rises and moreover no rising up is caused in the middle of the harness and thus wiring in a narrow part of a vehicle can be carried out easily.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness in which looseness of a bundle of electric wires is collected in a protector to prevent electric wires from protruding in the middle of the harness, and a method for manufacturing the same.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional method for manufacturing a wire harness described in Japanese Utility Model Laid-Open No. 61-180416. In this manufacturing method, a plurality of electric wires 29 are laid on a bifurcated support pin 28 which is erected at a main part of a harness wiring board 27, and a branch line 30b is branched from a main line 30a, and the main line is indicated by an arrow. The adhesive vinyl tape 31 is wound from one end a of the 30a to the other end or the branch line 30b,
The bundled electric wires 30 are bundled into one wire harness.

However, in the above-described conventional manufacturing method, a margin is set for the length of the electric wire 29 in order to ensure the connection with the connector of the terminal (not shown). Since the slack 32 is generated on the slack and the tape is wound from above the slack 32, the harness is partially raised and the appearance is not good (the product value is reduced), and the installation property to a narrow portion of the vehicle is deteriorated. There was a problem.

[0004]

SUMMARY OF THE INVENTION In view of the above points, the present invention provides a wire harness and a method for manufacturing the same, which can improve the appearance and the installation property to a narrow portion without causing the wire to loosen in the middle of the harness. The purpose is to provide.

[0005]

In order to achieve the above object, the present invention provides a wire harness in which a protector is arranged in the middle of a bundled wire, and the looseness of the wire generated in the bundled wire is contained in the protector. In a method of manufacturing a wire harness characterized by being assembled, and a wire harness in which a protector is arranged in the middle of a bundled electric wire, slack of the electric wire generated in the bundled electric wire is collected in the protector, and in the protector. A method of manufacturing a wire harness is characterized in that the slack base portion of the bundled electric wire is fixed by a fixing means such as a holding pin or a band.

[0006]

The bundled electric wire is handled by hand or tape-wrapped from both ends toward the protector, so that the slack is gradually brought closer to the protector side and finally gathered in the protector. The slack in the protector is held without wobbling by fixing the slack base portion of the bundled electric wires with a fixing means such as a holding pin or a band, and interference with the protector due to vehicle vibration (because of abnormal noise or damage to the harness) ) Is prevented.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a method for manufacturing a wire harness according to the present invention. In this manufacturing method, a bundled electric wire 3 (main line 3a and branch line 3b) is arranged on a support pin 2 of a harness wiring board 1, and a mounting table 6 is used at an intermediate portion of the bundled electric wire 3 to make a synthetic resin. Protector 4 is arranged, and the adhesive vinyl tape 5 is attached to the bundled electric wire 3 from both ends of the bundled electric wire 3 toward the protector 4, that is, each end portion (connector connection base portion) a of the trunk line 3a and the branch line 3b. , B toward the protector 4 as shown by the arrow.
Then, the slack of the trunk line 3a and the branch line 3b is sequentially gathered in the direction of the protector 4 along with the tape winding, and the protector 4
Gather inside.

FIG. 2 shows a state in which the protector 4 and the harness 7 are assembled.
The slacks 8 gathered as shown in (1) are collected in a convex shape in the center of the protector 4, and the left and right slack bases 8a of the bundled electric wires 3 are
8a is fixed by a pair of left and right holding pins 9 as a fixing means without backlash. The winding of the bundle of electric wires 3 is performed from the end of the protector 4 to a portion slightly inward, and the adhesive tape 10 for fixing is wound onto the protruding piece 11 at the end of the protector from above.

As shown in FIG. 3, the protector 4 has projecting pieces 11 and 11 extending from both ends of a bottom plate 12 and standing walls 13 and 14 standing in front and rear of the bottom plate 12 in a substantially gutter shape. Then, the accommodating portion 15 for the wire slack portion 8 is formed to bulge at the center of the one enclosure wall 13, and the accommodating portion 1 of the bottom plate portion 12 is formed.
5, each pair of the holding pins 9 and 9 in the transverse direction of the bottom plate portion 12 (direction orthogonal to the harness insertion direction) near both sides of
And a main body 4a provided with a cover engaging projection 16 on the outer surface of the other surrounding wall 14, and an upper opening 1 of the main body 4a.
7 to the top plate portion 18 for the enclosure wall 13, 1 of the main body 4a.
4 and an engaging edge portion 19 for the upper edge of the housing portion 15 is provided vertically, and the engaging claw 20 for the engaging protrusion 16 is provided on the edge portion 19.
And a cover 4b formed by hanging and connecting the.

The holding pin 9 is provided with an enclosing wall 13 of the main body 4a,
The electric wire which is projected at substantially the same height as 14 and is inserted between the holding pins 9 and 9 after the cover is closed does not come out of the pin. Then, as shown in FIG. 2, the slack portion 8 of the electric wire is accommodated in the accommodating portion 15 while being bent in a substantially U shape.

The accommodating portion 15 may not be provided when the slack portion 8 of the wire is small and the protector 4 has a large volume. Further, the slack portion 8 may be wound around and fixed to the holding pin 9, or the slack portion 8 and the slack base portion 8a may be wound with a tape.

Further, as shown in FIG. 4, instead of the holding pin 9, a pair of inward projections 21 and 21 may be integrally provided on the surrounding walls 13 'and 14' of the protector 4 '. The slack bases 8a 'and 8a' of the bundled electric wire 3'are stably held between the pair of opposed protrusions 21 and 21 without rattling.

Alternatively, as shown in FIG. 5, the slack base portions 8a "and 8a" of the bundled electric wire 3 "are bound by the resin bands 22 and 22, and the clip portion 23 of the band 22 is protected by the protector 4".
It may be locked in the insertion hole 24 of the surrounding wall 14 ″.

[0014]

As described above, according to the present invention, since the slack of the electric wire can be collected in the protector, the appearance of the harness is improved and the commercial value is improved, and the slack is not generated in the middle of the harness. Therefore, it is possible to easily route the vehicle to a narrow area. Furthermore, since the slack base is held by the fixing means in the protector,
Problems such as abnormal noise and harness wear due to vehicle vibration are also prevented.
