Abstract

A terminal fitting includes a cylindrical portion having a first crimping region and a second crimping region. A crimped state of a braided body extending through the terminal fitting is formed between the terminal fitting and a cable at the first crimping region such that relative movements of the terminal fitting and the braided body are prevented, and an end of the braided body is then folded back and positioned to face an outer surface of the cylindrical portion in a radial direction. The crimped state of the braided body is then formed between a sleeve and the terminal fitting at the second crimping region, so that the terminal fitting is fixed to the braided body.

First claim

What is claimed is:

1. A terminal fitting fixing structure comprising:
a braided body covering part of a cable including a core wire and an insulator, the braided body being formed by braided metal wires;
a terminal fitting having a cylindrical portion through which the braided body passes, and configured to be electrically connected with a ground member; and
a sleeve through which the cylindrical portion passes in a state in which a first end of the braided body being folded back at a first end of the terminal fitting in an axial direction is sandwiched between the sleeve and the cylindrical portion, wherein
the cylindrical portion has a first crimping region and a second crimping region in the axial direction,
in the first crimping region, the cylindrical portion is deformed radially inward and forms a crimped state of the braided body between the terminal fitting and the cable,
in the second crimping region, the sleeve is deformed radially inward, and forms a crimped state of the braided body at least between the sleeve and the terminal fitting,
the first crimping region and the second crimping region are disposed apart from each other in the axial direction so as to not overlap each other, and
the first crimping region is disposed closer to the first end of the terminal fitting than the second crimping region in the axial direction.

2. The terminal fitting fixing structure according to claim 1 , wherein
the terminal fitting has a flange protruding radially outward at a second end in the axial direction, and
the first end of the braided body is at least partially in contact with the flange.

3. The terminal fitting fixing structure according to claim 1 , wherein
the second crimping region is formed on a position closer to a second end of the terminal fitting than the first crimping region.

4. The terminal fitting fixing structure according to claim 2 , wherein
the second crimping region is formed on a position closer to the second end of the terminal fitting than the first crimping region.

5. The terminal fitting fixing structure according to claim 1 , wherein
the terminal fitting includes an inner surface, and
the braided body includes an outer surface that abuts the inner surface of the terminal fitting in the first crimping region.

6. The terminal fitting fixing structure according to claim 1 , wherein
the cylindrical portion extends in the axial direction from the first end of the terminal fitting to a second end of the terminal fitting,
the first crimping region extends axially from the first end of the terminal fitting to an intermediate location between the first end of the terminal fitting and a second end of the terminal fitting, and
the second crimping region extends axially from the second end of the terminal fitting to the intermediate location.

7. A wire harness comprising:
a cable including a core wire and an insulator;
a braided body covering part of the cable and being formed by braided metal wires;
a terminal fitting having a cylindrical portion through which the braided body passes, and configured to be electrically connected with a ground member; and
a sleeve through which the cylindrical portion passes in a state in which a first end of the braided body being folded back at a first end of the terminal fitting in the axial direction is sandwiched between the sleeve and the cylindrical portion, wherein
the cylindrical portion has a first crimping region and a second crimping region in the axial direction,
in the first crimping region, the cylindrical portion is deformed radially inward and forms a crimped state of the braided body between the terminal fitting and the cable,
in the second crimping region, the sleeve is deformed radially inward, and forms a crimped state of the braided body at least between the sleeve and the terminal fitting,
the first crimping region and the second crimping region are disposed apart from each other in the axial direction so as to not overlap each other, and
the first crimping region is disposed closer to the first end of the terminal fitting than the second crimping region in the axial direction.
