The outer surfaces of the pair of insertion pieces 18 are formed flush with the outer surface of the cylindrical portion 16 without providing a step or the like between the outer surfaces of the cylindrical portion 16.

  Since the pair of insertion pieces 18 are spaced apart from each other, they are disposed at a distance from each other along the circumferential direction of the electric wire 3 covered by the shield component 10 to which the shield fitting 11 is attached. Further, since the pair of insertion pieces 18 are spaced apart from each other, the shield insertion portion 17 is elastically deformable so that the pair of insertion pieces 18 come in contact with and away from each other. That is, the shield insertion part 17 is elastically deformable so that the insertion piece 18 side is particularly reduced in diameter (which means that the inner and outer diameters are reduced).

  The shield insertion portion 17 is elastically deformed in a direction in which the insertion pieces 18 approach each other, and is press-fitted into the braided wire 12. The shield insertion portion 17 presses the braided wire 12 from the inner side toward the outer side over substantially the entire circumference by the elastic restoring force of the insertion piece 18.

Then, the caulking blade 25 abuts on the outer sheath 13 of the shield component 10 and breaks through the outer sheath 13. The caulking blade 25 is in contact with the braided wire 12. Thus, the caulking portion 20 clamps the braided wire 12 with the braided wire 12 sandwiched between the insertion piece 18 of the shield insertion portion 17.

  In the shield metal 11 having the above-described configuration, the insertion piece 18 is inserted into the braided wire 12. Then, as shown in FIGS. 2 and 3, the braided wire 12 is caulked with a caulking piece 22. In this way, the braided wire 12, that is, the shield component 10 is attached to the shield metal 11. That is, the shield structure 1 having the above-described configuration is assembled. Hereinafter, the assembly method of the shield structure 1 will be described in detail.

The caulking blade 25 passes through the outer sheath 13 and comes into contact with the braided wire 12. Thus, as shown in FIG. 13, the braided wire 12 of the shield component 10 is crimped by being sandwiched between the caulking blade 25, that is, the caulking portion 20 and the insertion piece 18 of the shield insertion portion 17. Thus, the shield structure 1 having the above-described configuration is assembled.

  After the terminal fitting 6 is attached to the end of the electric wire 3, the component insertion portion 21 of the shield fitting 11 is press-fitted into the shield component 30 embedded in the connector housing 7, and the shield structure 1 is attached to the connector 2.

Therefore, the shield insertion part 17 can be easily inserted into the braided wire 12, and the labor involved in assembling the shield structure 1 can be suppressed. Furthermore, since the shield insertion part 17 can be easily inserted into the braided wire 12, the shield structure 1 can be assembled easily and accurately.

  Since the caulking portion 20 includes the caulking piece 22, the braided wire 12 can be caulked by the caulking portion 20 by bending the caulking piece 22. For this reason, the shield structure 1 can be assembled by inserting the shield insertion portion 17 into the braided wire 12 while the braided wire 12 is covered with the outer sheath 13 by bending the caulking piece 22 or the like.

  A plurality of caulking pieces 22 are provided, and the plurality of caulking pieces 22 are arranged side by side along the circumferential direction of the electric wire 3 as a shielded object. For this reason, when caulking with the caulking piece 22, that is, the caulking portion 20, the caulking piece 22, that is, the caulking blade 25, is arranged in parallel along the circumferential direction of the electric wire 3. Therefore, the shield metal 11 can be reliably fixed without rattling with the braided wire 12.

  The shield insertion portion 17 includes a plurality of insertion pieces 18, and the insertion pieces 18 are arranged in the circumferential direction of the electric wire 3.
