Abstract

A sleeve surrounds an exposed part extending forward of the sheath, out of the shield layer, and is crimped to an outer peripheral surface of the insulation coating. A crimping portion of an outer conductor of a shield terminal is crimped to the sleeve while surrounding the sleeve and a region behind the sleeve, out of the insulation coating. An inner peripheral side locking portion and an outer peripheral side locking portion are formed in a region covering the insulation coating, out of the crimping portion. The inner peripheral side locking portion is located more radially inward than a region surrounding the sleeve, out of the crimping portion. The outer peripheral side locking portion is locked to the inner peripheral side locking portion while being accommodated in a recess in an outer peripheral surface of the inner peripheral side locking portion.

First claim

1 . A shielded electrically conductive path, comprising:
a shielded cable including an insulation coating surrounding a core wire, a shield layer surrounding the insulation coating and a sheath surrounding the shield layer; a sleeve surrounding an exposed part extending forward of the sheath, out of the shield layer, the sleeve being crimped to an outer peripheral surface of the insulation coating; and a shield terminal including an outer conductor, a crimping portion in the form of an open barrel formed in a rear end part of the outer conductor being crimped to the sleeve while surrounding the sleeve and a region behind the sleeve, out of the insulation coating, an inner peripheral side locking portion and an outer peripheral side locking portion being formed in a region covering the insulation coating, out of the crimping portion, the inner peripheral side locking portion being located more radially inward than a region surrounding the sleeve, out of the crimping portion, and the outer peripheral side locking portion being locked to the inner peripheral side locking portion while being accommodated in a recess in an outer peripheral surface of the inner peripheral side locking portion.

2 . The shielded electrically conductive path of claim 1 , wherein the crimping portion is formed with a retaining portion arranged at a position in contact with the sleeve from behind or closely facing the sleeve from behind.

3 . The shielded electrically conductive path of claim 2 , wherein the retaining portion continuously extends over at least more than a semiperimeter in a circumferential direction.

4 . The shielded electrically conductive path of claim 2 , wherein the inner peripheral side locking portion is formed in the retaining portion.

5 . The shielded electrically conductive path of claim 1 , wherein a depth of the recess is equal to or larger than a plate thickness of the crimping portion.

6 . The shielded electrically conductive path of claim 1 , wherein:
one of the inner peripheral side locking portion and the outer peripheral side locking portion is formed with a locking hole, and the other of the inner peripheral side locking portion and the outer peripheral side locking portion is formed with a locking protrusion to be locked into the locking hole.

7 . The shielded electrically conductive path of claim 6 , wherein an opening dimension in a front-rear direction of the locking hole is set to be larger than a dimension in the front-rear direction of the locking protrusion.

8 . The shielded electrically conductive path of claim 6 , wherein an opening dimension in a circumferential direction of the locking hole is set to be larger than a dimension in the circumferential direction of the locking protrusion.

9 . The shielded electrically conductive path of claim 6 , wherein:
the locking hole is formed in the inner peripheral side locking portion, and the locking protrusion is formed on the outer peripheral side locking portion.

10 . The shielded electrically conductive path of claim 6 , wherein the locking protrusion is shaped by bending a part of the inner peripheral side locking portion or the outer peripheral side locking portion into a folded shape.

11 . The shielded electrically conductive path of claim 6 , wherein the locking protrusion is shaped by cutting and raising a part of the inner peripheral side locking portion or the outer peripheral side locking portion in a plate thickness direction.

12 . The shielded electrically conductive path of claim 6 , wherein the locking protrusion is shaped by bending the inner peripheral side locking portion or the outer peripheral side locking portion along a fold line in a circumferential direction.
