Abstract

A shield structure includes a hollow tubular shield member, a shield shell having a plate-like shell body which is formed with a through hole, and a plate-like bent piece which is extended from an inner edge of the shell body that defines the through hole and which is bent to rise from the shell body, and an annular member which surrounds and fastens the bent piece, wherein at least one bent piece of the shield shell is extended from the inner edge of the shell body, and when the annular member surrounds and fastens the bent piece an outer surface of which is covered with a leading end in the longitudinal direction of the shield member, the leading end is clamped between the annular member and the bent piece.

First claim

What is claimed is:

1. A shield structure comprising:
a hollow tubular shield member, the shield member being hollow in a longitudinal direction and having a first end and a second end, opposite to the first end, in the longitudinal direction;
a shield shell having a plate-like shell body which is formed with a through hole, and a plate-like bent piece which is extended from an inner edge of the shell body that defines the through hole and which is bent to rise from the shell body; and
an annular member which surrounds and fastens the bent piece,
wherein at least one bent piece of the shield shell is extended from the inner edge of the shell body, and
when the annular member surrounds and fastens the bent piece, with an outer surface of the bent piece being covered with the first end of the shield member, the first end of the shield member is clamped between the annular member and the bent piece.

2. The shield structure according to claim 1 , wherein the shield shell has a plurality of bent pieces including the at least one bent piece, the plurality of bent pieces being extended from the inner edge of the shell body, and
two of the plurality of the bent pieces are formed so that planes including the bent pieces which are bent are parallel to each other or intersect.

3. The shield structure according to claim 2 , wherein at least two of the plurality of bent pieces are formed to be parallel to each other and the entire surfaces of the at least two of the bent pieces face each other.

4. The shield structure according to claim 1 , further comprising a housing which holds an electric wire,
wherein an outer surface of the housing, which faces an inner surface of the bent piece when the shell body is attached to penetrate the through hole, is flat, and
the inner surface of the bent piece which is fastened by the annular member is supported on the outer surface of the housing.

5. The shield structure according to claim 1 , wherein the outer surface of the bent piece is provided with a protrusion or a ridge.

6. The shield structure according to claim 5 , wherein an inner surface of the bent piece is formed with a concave or a groove at a position corresponding to the protrusion or the ridge.

7. A method of manufacturing a shield connector with electric wire comprising:
a pressing step of forming a shield shell by pressing a metal plate, the shield shell having a plate-like shell body formed with a through hole, and at least one bent piece extended from an inner edge of the shell body that defines the through hole, the at least one bent piece being bent to rise from the shell body;
an arranging step of arranging a first end, in a longitudinal direction, of a shield member to the shell body to surround the through hole, the shield member being formed in a hollow tubular shape, wherein the shield member is hollow in the longitudinal direction and includes the first end and a second end, opposite to the first end, in the longitudinal direction; and
a fastening step of clamping the first end of the shield member between the bent piece and an annular member by surrounding and fastening the bent piece, an outer surface of which is covered with the leading end of the shield member, with the annular member.
