Abstract

PURPOSE:To very easily achieve electromagnetic shielding of wire harnesses. CONSTITUTION:Braids 15 are formed in connection with a plurality of wire harnesses using a braiding machine, and the braid 15 between adjacent wire harnesses 3 is cut out to separate the wire harnesses 3 from one another. Therefore, electromagnetic shielding of the wire harnesses 3 is very easily achieved by simply cutting out the braid 15 between adjacent wire harnesses 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness shielding method for applying an electromagnetic shield to the outside of a wire harness.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, when an electromagnetic shield is applied to the outside of a wire harness 3 which is formed by connecting a connector 2 to both ends of several electric wires 1 bundled by a tape or the like, as shown in FIG. In this way, the wire harness 3 is electromagnetically shielded by inserting the wire harness 3 into the braided tube 4 prepared in advance.

The technique of inserting the wire harness into the braided tube is disclosed in, for example, Japanese Utility Model Laid-Open No. 3-120624.

[0004]

However, in the conventional shield method, the wire harnesses 3 must be inserted one by one into the braided tube 4, which is very troublesome.

Therefore, the present invention has been made to solve the above problems, and an object thereof is to make it possible to perform electromagnetic shielding of a wire harness extremely easily.

[0006]

SUMMARY OF THE INVENTION A method for shielding a wire harness according to the present invention comprises a braiding machine for forming a braid on the outside of a long member such as an electric wire, in which a connector is connected to both ends of several bundled electric wires. It is characterized in that the braids are continuously braided on the outer side of the plurality of wire harnesses formed as described above, and then the braids between the adjacent wire harnesses are cut to separate the respective wire harnesses.

[0007]

According to the present invention, the braids are continuously braided into a plurality of wire harnesses by the braiding machine, and then the braids between the adjacent wire harnesses are cut, so that the wire harnesses are separated by cutting the braids. The electromagnetic shield of the wire harness can be performed only by itself, and it is possible to extremely easily perform the electromagnetic shield of the wire harness without the labor required in the past.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view of a step in the middle of one embodiment of the method for shielding a wire harness of the present invention, and FIG. 2 is a perspective view.
3 is a perspective view of a part of FIG. 2, FIG. 4 is an explanatory view of a step different from FIG. 1, and FIG. 5 is an explanatory view of an electromagnetically shielded wire harness.

The wire harness 3 is continuously inserted (broken line arrow in FIG. 1) from below the braiding part of the braiding machine 11 having a well-known structure for forming a braid on the outside of a long member such as an electric wire. Braid the braid into 3.

By the way, the braiding machine itself is disclosed in, for example, Japanese Unexamined Patent Publication No.
This is well known as disclosed in Japanese Patent No. 214489, and there are various configurations other than the configuration described in this publication, and the braiding machine 11 in FIG. 1 is also a known configuration and its schematic configuration. To explain, as shown in FIG.
A plurality of wire reels 14 are arranged along the inner circumference of the short cylindrical frame body 13, and each wire reel 14 simultaneously rotates in the same direction along the inner circumference of the frame body 13 so that the braided portion is formed. In, the braid 15 is formed, and the braid 15 is wound up by the take-up reel (not shown) via the guide reel 16 provided above the frame 13.

The braiding portion of the braiding machine 11 is a cylindrical body 1 fixedly installed in the center of the frame 13 as shown in FIG.
As shown in FIG. 3, the wire harness 3 is inserted into the inside of the cylindrical body 17 from below, and the wire harness 3 is inserted into the outside of the wire harness 3 by the rotation of each wire reel 14 above the cylindrical body 17. The braid 15 is formed.

Next, of the braids 15 wound on the take-up reel as described above, the braids 15 between the adjacent wire harnesses 3 are cut as shown in FIG. 4 (1 in FIG. 4).
As shown in FIG. 5, by separating each wire harness 3 with both connectors 2 covered with the braid 15 as shown in FIG. 5, and then unraveling both ends of the braid 15 to expose both connectors 2, the same as in the conventional case. The wire harness 3 in which only the electric wire portion is covered with the braid 15 and electromagnetically shielded is completed.

Therefore, the electromagnetic shielding of the wire harness 3 can be performed only by continuously forming the braids 15 on the plurality of wire harnesses 3 by the braiding machine 11 and then cutting the braids 15 between the adjacent wire harnesses 3. Therefore, compared to the conventional case where the wire harness is inserted through the braided tubes one by one, the labor can be significantly reduced.

It goes without saying that the structure of the braiding machine 11 is not limited to the above.

[0015]

As described above, according to the wire harness shielding method of the present invention, the braid is continuously formed on the plurality of wire harnesses by the braiding machine, and the braid between the adjacent wire harnesses is cut. As a result, the electromagnetic shielding of the wire harness can be performed much more easily than before, and the work efficiency can be improved.
